The present invention relates to a specimen processing method, a specimen processing system, and a sealing device used for measuring a urine specimen.
Japanese Laid-Open Patent Publication No. 2017-44631 discloses a urine analyzer for analyzing a urine specimen. When a urine specimen is analyzed, a urine specimen of a subject is collected in a urine collection cup, a fixed quantity of the urine specimen is taken into a specimen container from the urine collection cup, and the specimen container is set in a urine analyzer. The urine analyzer aspirates the urine specimen from an upper opening of the specimen container by using an aspiration tube, and analyzes the urine specimen.
The scope of the present invention is defined solely by the appended claims, and is not affected to any degree by the statements within this summary.
Odor of the urine specimen contained in the specimen container set in the urine analyzer is released from the container during measurement, or odor of the urine specimen preserved in the specimen container for a retest leaks through the container during preservation. Such odor makes a user feel unpleasant.
A specimen processing method according to a first aspect of the present invention is, as shown in
A specimen processing system (100) according to a second aspect of the present invention, as shown in
A specimen processing method according to a third aspect of the present invention is, as shown in
A sealing device (300) according to a fourth aspect of the present invention is, as shown in
A specimen processing method according to a fifth aspect of the present invention is a method of processing, by a specimen processing device, a urine specimen contained in a specimen container (80) having an opening. The method includes: sealing, with a seal, an opening of the specimen container (80) containing the urine specimen; forming, by a puncture member of the specimen processing device, a through-hole in the seal with which the specimen container (80) is sealed; aspirating the urine specimen in the specimen container (80) through the through-hole by using an aspiration tube (32); and processing the aspirated urine specimen.
Hereinafter, embodiments will be described with reference to the drawings.
With reference to
The specimen processing system 100 shown in
In the example of
Each unit will be described with reference to
The loading unit 110 has a function of providing a place for the specimen containers 80 to be loaded into the specimen processing system 100, and sending each loaded specimen container 80 toward the downstream side. Each specimen container 80 contains a urine specimen 90 (see
The loading unit 110 (see
The controller 113 described later in detail is configured to be communicable with a host computer 500. The controller 113 can acquire specimen information registered in the host computer 500, by using identification information acquired by the information reader 114. The specimen information includes various kinds of information, related to specimen processing, such as items to be measured by the specimen processing unit 140 and the specimen processing unit 150, presence/absence of a cap, necessity of sealing with a seal, and the like. The transport controller 112 includes a processor and a memory. The transport controller 112 controls the transport device 111 so as to transport the specimen rack 85 to the uncapping unit 120. The transport controller 112 performs mutual communication with transport controllers of the other units in the specimen processing system 100, and controls a transport start timing for the specimen rack 85 in accordance with the states of the transport device in the respective units.
The uncapping unit 120 is configured to receive the specimen rack 85 from the loading unit 110, and perform an uncapping process on each specimen container 80 set in the specimen rack 85. That is, the uncapping unit 120 is configured to remove a cap 84 from a specimen container 80 having an opening 81 to which the cap 84 is attached. The uncapping unit 120 is configured to send, to the sealing unit 130, the specimen container 80 from which the cap 84 has been removed through the uncapping process.
The uncapping unit 120 (see
The sealing unit 130 is configured to seal, with a film 75, a specimen container 80 from which a cap 84 has been removed. Thus, the specimen processing method of the present embodiment further includes a step of removing a cap 84 from a specimen container 80 having an opening 81 to which the cap 84 is attached, and a step of sealing, with a film 75, the specimen container 80 from which the cap 84 has been removed. Thus, even when the cap 84 has been attached to the specimen container 80 in advance, the cap 84 can be replaced with the film 75 through which an aspiration tube 32 can penetrate. Therefore, the user need not remove a cap 84 from each specimen container 80 before loading the specimen containers 80 into the specimen processing unit 140. Moreover, a time period during which the opening 81 of each specimen container 80 is opened can be limited to a time period from when the cap 84 is removed to when the opening 81 is sealed with the film 75. Therefore, it is possible to effectively reduce release of odor of the urine specimen 90 to the outside of the specimen container 80.
The sealing unit 130 (see
The specimen processing unit 140 aspirates, by using the aspiration tube 32, the urine specimen 90 (see
The specimen processing unit 140 (see
The transport device 141 includes a first transport path 141a, a second transport path 141b, a loading/storage part 141c, and a sending/storage part 141d, and is capable of receiving/transporting a specimen rack 85 from/to the second transport path 141b. The first transport path 141a, the second transport path 141b, the loading/storage part 141c, and the sending/storage part 141d form a loop path, so that the transport device 141 can circularly transport the specimen rack 85 for a retest. The second transport path 141b allows the transport device 141 to transport the specimen rack 85 from the sealing unit 130 to the specimen processing unit 150 not through the specimen processing device 145.
The controller 143 acquires measurement order information from the host computer 500 on the basis of identification information read by the information reader 144. On the basis of the measurement order information, the controller 143 controls the operation of the specimen processing device 145 so as to perform or so as not to perform specimen aspiration from each of individual urine specimens 90 (individual specimen containers 80). The controller 143 controls the operation of the specimen processing device 145 so as not to perform specimen aspiration from a specimen container 80 for which specimen processing by the specimen processing unit 140 is not required according to the measurement order information.
The transport controller 142 includes a processor and a memory. The transport controller 142 controls the transport device 141 so as to receive the specimen rack 85 from the sealing unit 130 and transport the specimen containers 80 held in the specimen rack 85 one by one to the reading position P4 and the aspiration position P5. The transport controller 142 controls the transport device 141 so as to transport, to the specimen processing unit 150, the specimen rack 85 holding the specimen containers 80 having been subjected to specimen aspiration.
The specimen processing unit 150 aspirates, by using the aspiration tube 32, the urine specimen 90 (see
The specimen processing unit 150 (see
The transport device 151 is configured to transport the specimen rack 85 between the specimen processing unit 140 and the second sealing unit 160. The transport device 151 transports the specimen containers 80 held in the specimen rack 85 to a reading position P6 (see
The transport device 151, similar to the transport device 141, includes the first transport path 151a, a second transport path 151b, a loading/storage part 151c, and a sending/storage part 151d. The second transport path 151b allows the transport device 151 to transport the specimen rack 85 from the specimen processing unit 140 to the collection unit 170 not through the specimen processing device 155. The controller 153 acquires measurement order information from the host computer 500 on the basis of identification information read from the information reader 154. On the basis of the measurement order information, the controller 153 controls the operation of the specimen processing device 155 so as to perform or so as not to perform specimen aspiration from each of the individual urine specimens 90 (individual specimen containers 80). As for a specimen container 80 having been subjected to specimen aspiration in the upstream-side specimen processing unit 140, the film 75 thereof is again punctured by the aspiration tube 32 of the specimen processing device 155.
The transport controller 152 controls the transport device 151 so as to receive the specimen rack 85 from the specimen processing unit 140 and transport the specimen containers 80 held in the specimen rack 85 one by one to the reading position P6 and the aspiration position P7. The transport controller 152 controls the transport device 151 so as to transport, to the second sealing unit 160, the specimen rack 85 holding specimen containers 80 having been subjected to specimen aspiration or specimen containers 80 not to be subjected specimen processing.
The second sealing unit 160 is configured to re-seal, with a film 75, the opening 81 of each specimen container 80 from which the urine specimen 90 has been aspirated. Thus, the specimen processing method of the present embodiment further includes a step of re-sealing, with a film 75, an opening 81 of a specimen container 80 whose film 75 has been punctured by the aspiration tube 32 and from which a urine specimen 90 has been aspirated. The second sealing unit 160 performs the re-sealing process such that the previously attached film 75 is not removed from the specimen container 80 and is covered with the new film 75.
Thus, even when the through-hole TH is formed by the aspiration tube 32 in the film 75 attached to the opening 81 before aspiration, the opening 81 can be re-sealed with the new film 75, whereby release of odor of the urine specimen 90 to the outside of the specimen container 80 can be reduced more effectively. Moreover, since the opening 81 can be re-sealed with the film 75, the specimen container 80 having been subjected to specimen aspiration can be preserved for a retest or the like.
The hardware configuration of the sealing unit 160 is similar to that of the upstream-side sealing unit 130. The transport device 161 is configured to transport the specimen rack 85 between the specimen processing unit 150 and the collection unit 170. Moreover, the transport device 161 transports the specimen containers 80 held in the specimen rack 85 to a sealing position P8 (see
The transport controller 162 controls the transport device 161 so as to receive the specimen rack 85 from the specimen processing unit 150 and transport the specimen containers 80 held in the specimen rack 85 one by one to the sealing position P8 in the sealing device 300. The transport controller 162 controls the transport device 161 so as to transport, to the collection unit 170, the specimen rack 85 holding the specimen containers 80 having been subjected to the sealing process.
The collection unit 170 has a function of receiving the specimen containers 80 having been subjected to specimen processing by the specimen processing system 100, and providing a storage place for the received specimen containers 80. The collection unit 170 includes a transport device 171 and a transport controller 172. The transport device 171 is configured to receive the specimen rack 85 from the sealing unit 160, and transport the received specimen rack 85 to the storage position. The transport controller 172 includes a processor and a memory. The transport controller 172 controls a timing to receive the specimen rack 85 by the transport device 171, and controls the transport device 171 so as to transport the received specimen rack 85 to the storage position.

When the specimen container 80 to be uncapped is located at the uncapping position P2 (see
The container holder 210 includes hand members 211 for holding a specimen container 80, an opening/closing drive part 212 for the hand members 211, and an up-down drive part 213 for the hand members 211. Specifically, a pair of hand members 211 are disposed opposing each other such that a specimen container 80 can be placed therebetween. As shown in
The cap holder 220 (see
As shown in
Referring back to
The horizontal drive part 225 includes a holding member 225a which holds the hand members 221, the opening/closing drive part 222, the up-down drive part 223, and the rotation drive part 224, on a rail 225b, movably in the horizontal direction. The rail 225b extends along the Y direction. The horizontal drive part 225 causes a motor 225c to rotate a driving pulley 225d attached to an output shaft of the motor 225c, thereby rotating a belt 225f between the driving pulley 225d and a driven pulley 225e. The holding member 225a is connected to the belt 225f. Thus, the horizontal drive part 225 horizontally moves the pair of hand members 221 held by the holding member 225a to a position above the specimen container 80 held by the container holder 210 (i.e., a position immediately above the uncapping position P2) and to a stand-by position P2a off from the position above the specimen container 80. A chute part 204 connected to a collection container 203 is disposed beneath the stand-by position P2a.
The controller 123 (see
In step S11 shown in
In step S12, the controller 123 controls the horizontal drive part 225 so as to move the pair of hand members 221 to the position above the uncapping position P2.
In step S13, the controller 123 controls the container holder 210 and the cap holder 220 so as to remove a cap 84 from the specimen container 80. Firstly, the controller 123 controls the up-down drive part 213 so as to pull the specimen container 80 held by the hand members 211 upward from the specimen rack 85. Moreover, the controller 123 controls the up-down drive part 223 so as to move the pair of hand members 221 downward such that the cap 84 is placed between the pair of hand members 221.
Next, the controller 123 controls the opening/closing drive part 222 (pressure source 202) so as to close the pair of hand members 221. The cap 84 of the specimen container 80 is held by the pair of hand members 221. Next, the controller 123 controls the up-down drive part 223 and the rotation drive part 224 such that the pair of hand members 221 are moved upward while being rotated (see
The controller 123 changes the rotation angle of the hand members 221 on the basis of the identification result of the container identification part 201. According to the type of the cap 84 identified, the rotation angle is set to a predetermined angle, e.g., 450° for a screw-type cap 84, 90° for a push-in type cap 84, or the like. The pair of hand members 221 may be rotated while being closed, may be rotated in a reverse direction while being opened, and may be rotated again while being closed. This control is useful when the angle of rotation of the hand members 221 by the rotation drive part 224 is limited. The cap 84 can be rotated by an arbitrary angle by performing the rotation operation a plural number of times.
Thereafter, in step S14, the controller 123 controls the up-down drive part 213 so as to move the specimen container 80 held by the hand members 211 downward and return the specimen container 80 to the specimen rack 85. Then, the controller 123 controls the opening/closing drive part 212 (pressure source 202) so as to open the pair of hand members 211. Thus, holding of the uncapped specimen container 80 is released, and the specimen container 80 held by the pair of hand members 211 is returned to the specimen rack 85. In this case, the controller 123 may control the amount of the downward movement of the pair of hand members 211 by the up-down drive part 213 so as to adjust the depth at which the specimen container 80 is inserted in the specimen rack 85. This avoids peeling of the identification label 83 (see
In step S15, the removed cap 84 is collected. The controller 123 controls the horizontal drive part 225 so as to move the pair of hand members 221 to the stand-by position P2a. The controller 123 controls the opening/closing drive part 222 (pressure source 202) so as to open the pair of hand members 221. Then, the cap 84 held by the pair of hand members 221 falls downward from the stand-by position P2a into the chute part 204. The cap 84 is collected into the collection container 203 through the chute part 204. When a predetermined number of caps 84 have been stored in the collection container 203, the collection container 203 is removed by the user, and the caps 84 are discarded, or washed and reused.
With reference to
A seal that the sealing unit 130 uses for sealing an opening 81 of a specimen container 80 is obtained by adhering a thin member made of a resin, a metal, or the like, to an edge of the opening 81 and a peripheral wall, near the edge, of the specimen container 80 through bonding, thermal welding, cohesion, or the like.
As described above, in the present embodiment, the seal (second seal) is the film 75. In this specification, “film” means a thin film-like member, and represents a broad concept including “sheet”, “membrane”, and “foil”. As for the film 75 as the seal, a combination of a constituent material and a thicknesses thereof is limited within a range in which the aspiration tube 32 can puncture the film 75.
Therefore, the opening 81 of the specimen container 80 can be easily sealed with the film 75 which can be easily punctured, and release of odor can be effectively reduced by the film 75. Although a rubber cap is conceivable as a seal that can be punctured by the aspiration tube 32, great force is required for puncturing through the rubber cap. The film 75, which is sufficiently thinner than such a rubber cap, is preferable because it allows use of an aspiration mechanism having a simple structure.
Specifically, the film 75 is a stretchable resin film. The stretchable resin film has excellent sealability, and therefore can effectively reduce release of odor of a urine specimen from a specimen container. As the stretchable resin film, a film that is irreversibly stretchable and exhibits self-adhesiveness when being stretched is preferably used.
Thus, the film 75 can be stretched and adhered to the specimen container 80. Therefore, it is possible to realize a sealing structure by which the opening 81 of the specimen container 80 can be easily sealed and the sealing is not easily released.
The stretchable resin film is a plastic paraffin film, for example. The thickness of the resin film is, for example, 1 mm or less, preferably 0.5 mm or less, and more preferably 0.2 mm or less.
Each of the sealing unit 130 and the sealing unit 160 (see
A schematic configuration of the sealing device 300 of the present embodiment will be described. As shown in
The film holder 41 is configured to hold a film 75 as a seal. The container holder 42 is configured to hold a specimen container 80 containing a urine specimen 90. The up-down drive part 43 is configured to drive the film holder 41 in the up-down direction (Z direction). The rotation drive part 44 is configured to drive and rotate the film holder 41 around the center axis of the specimen container 80. The up-down drive part 43 may drive the container holder 42 in the up-down direction, and the rotation drive part 44 may drive and rotate the container holder 42 around the center axis of the specimen container 80.
The controller (133, 163) is configured to perform control of winding the film 75 held by the film holder 41 around the specimen container 80 by operating the rotation drive part 44 while the film 75 is pressed by the up-down drive part 43 against the opening edge of the specimen container 80 held by the container holder 42.
As shown in
As described above, the sealing device 300 of the present embodiment is provided with the controller (133, 163) which performs control of winding the film 75 held by the film holder 41 around the specimen container 80 by operating the rotation drive part 44 while the film 75 is pressed against the opening edge of the specimen container 80 held by the container holder 42. Thus, the opening 81 of the specimen container 80 is sealed with the film 75. Therefore, specimen aspiration can be performed by the aspiration tube 32 penetrating through the film 75 while the opening 81 is sealed with the film 75. Therefore, release of odor can be reduced when the urine specimen is aspirated in the specimen processing. Although a hole is formed in a portion of the film 75 after the specimen aspiration, release of odor can be effectively reduced as compared to the case where the opening 81 is fully opened.
In the specimen processing method of the present embodiment, the step of sealing the opening 81 of the specimen container 80 with the seal includes: the step of stretching the film 75 by pressing the opening edge of the specimen container 80 against the film 75; and the step of winding the seal around the specimen container 80 by rotating the stretched film 75 around the center axis of the specimen container 80.
Therefore, sealing can be performed such that the film 75 is wound around the opening edge and the side surface of the specimen container 80 after the opening 81 of the specimen container 80 is sealed with the film 75. As a result, the opening 81 of the specimen container 80 can be firmly sealed, thereby effectively preventing not only leakage of odor but also leakage of the urine specimen 90 when the specimen container 80 is tilted or the urine specimen 90 is agitated.
As shown in
The film piece supply mechanism 310 is configured to hold a film roll FR (i.e., rolled film 75), and feed the film 75 to the film holder 331 disposed at the film holding position P11 (see
The film piece supply mechanism 310 includes a film feeder 311 and a cutter mechanism 312. As shown in
The cutter mechanism 312 cuts the film 75 fed out from the pair of feeding rollers 311b to separate the film 75 fed to the film holder 331 from the film roll FR. As shown in
As shown in
The container holder 321 is composed of a pair of hand members 321a for holding a specimen container 80. The pair of hand members 321a are disposed opposing each other so that the specimen container 80 can be placed therebetween. The opening/closing drive part 322 (see
The sealing mechanism 330 (see
The film holder 331 holds a film piece supplied from the film piece supply mechanism 310. As shown in
In the configuration example shown in
The pressing part 335 is disposed at the inner side of the recess 331d of the second member 331b so as to oppose the held film piece. The pressing part 335 has a shape protruding from the second member 331b toward the first member 331a (protruding downward). The pressing part 335 is formed of an elastic body, and is rotatably mounted to the second member 331b. Examples of the elastic body include rubber, sponge, and elastomer. When the opening 81 of the specimen container 80 is sealed (see
As shown in
The rotation drive part 333 causes a motor 333a to rotate a driving pulley 333b attached to an output shaft of the motor 333a, thereby rotating, via a belt 333c, a driven pulley 333d connected to the film holder 331. Thus, the rotation drive part 333 causes the film holder 331 including the first member 331a and the second member 331b to rotate around a center axis of the specimen container 80 (i.e., a vertical axis along the Z direction).
The horizontal drive part 334 has a holding member 334a that holds the film holder 331 so as to be horizontally movable on a rail 334b. The rail 334b extends along the Y direction. The horizontal drive part 334 causes a motor 334c to rotate a driving pulley 334d attached to an output shaft of the motor 334c, thereby rotating a belt 334e between the driving pulley 334d and a driven pulley 334f. The holding member 334a is connected to the belt 334e. Thus, the horizontal drive part 334 horizontally moves the film holder 331 and the rotation drive part 333 held by the holding member 334a to the position P12 above the specimen container 80 held by the container holder 321 (i.e., immediately above the sealing position P3), the film holding position P11, and the film disposal position P13.
In the present embodiment, a portion, of the film 75 held by the film holder 331 (see
Specifically, the controller (133, 163) (see
Thus, a tensile fracture of the film 75 is caused by rotation, and the film 75 wound around the specimen container 80 can be separated from the film holder 331. As a result, both sealing of the opening 81 with the film 75 and removal of the residual portion of the sealed film 75 can be realized by rotation which is a simple operation. Since the excess film 75 is removed from the specimen container 80, handling of the sealed specimen container 80 is facilitated.
Specifically, firstly, as shown in
As shown in
As shown in
Thereafter, as shown in
As described above, in the configuration of separating the residual portion RP of the film 75 from the specimen container 80, the residual portion RP (see
Thus, the residual portion RP, of the film 75, which has been separated from the specimen container 80 and held on the film holder 331 side, can be removed by the film removal part 341, whereby the subsequent sealing process can be readily performed.
As shown in
With the first member 331a of the film holder 331 being apart from the second member 331b, the film removal part 341 catches a part of the residual portion RP of the film 75 and brings the residual portion RP to the disposal part 345, thereby discarding the residual portion RP.
As shown in
In the first member 331a and the second member 331b of the film holder 331, a cutout 336 is formed such that a part of the residual portion RP of the film 75 is exposed. When the film holder 331 is located at the film disposal position P13 with the distance between the pair of sandwiching members 342 being increased, the residual portion RP of the film 75 exposed from the cutout 336 of the film holder 331 is placed between the pair of sandwiching members 342.
At this time, the controller 133 controls the opening/closing drive part 332 so as to increase the distance between the first member 331a and the second member 331b such that holding by the film holder 331 is released, and controls the sandwiching drive part 343 so as to close the pair of sandwiching members 342 such that the film removal part 341 grasps the residual portion RP. Then, the controller 133 controls the up-down drive part 344 so as to move the pair of sandwiching members 342 downward to the disposal part 345. When the pair of sandwiching members 342 sandwiching the residual portion RP moves downward, the residual portion RP is removed from the film holder 331. Thereafter, the controller 133 controls the sandwiching drive part 343 so as to open the pair of sandwiching members 342 that has entered the disposal part 345. Thus, the residual portion RP having been sandwiched by the pair of sandwiching members 342 is collected into the disposal part 345.
The operation flow of the above sealing process will be described with reference to
In step S21, the controller 133 performs control of causing the film piece supply mechanism 310 to supply the film 75 to the film holder 331. The controller 133 controls the horizontal drive part 334 so as to locate the film holder 331 at the film holding position P11. The controller 133 controls the roller drive part 311c so as to feed the film 75 to a space between the first member 331a and the second member 331b of the film holder 331. The controller 133 controls the cutter drive part 312c so as to cut the fed film 75 and separate the same from the film roll FR.
In step S22, the film 75 is held. The controller 133 controls the opening/closing drive part 322 such that the film 75 supplied from the film piece supply mechanism 310 is sandwiched by the first member 331a and the second member 331b.
In step S23, the specimen container 80 is held. The controller 133 controls the opening/closing drive part 322 such that the pair of hand members 321a holds a specimen container 80 in the specimen rack 85 transported to the sealing position P3. The controller 133 controls the horizontal drive part 334 so as to locate the film holder 331 to the position P12 above the sealing position P3. The controller 133 controls the up-down drive part 323 such that the pair of hand members 321a holding the specimen container 80 is moved upward and placed in a space (corresponding to the through-hole 331c and the recess 331d) in the film holder 331. Thus, the opening edge at the upper end of the specimen container 80 is adhered to the film 75, and the film 75 is pushed into the opening 81 by the pressing part 335 (see
In step S24, the opening 81 is sealed. The controller 133 controls the rotation drive part 333 so as to rotate the film holder 331 such that the film 75 held by the film holder 331 is wound around the outer peripheral surface of the specimen container 80. The controller 133 operates the rotation drive part 333 until the film 75 wound around the specimen container 80 is separated from the film 75 held by the film holder 331. Thus, the specimen container 80 is sealed with the film 75, and the film 75 wound around the specimen container 80 is separated from the residual portion RP of the film 75 held by the film holder 331 (see
In step S25, holding of the specimen container 80 is released. The controller 133 controls the up-down drive part 323 so as to move the pair of hand members 321a holding the specimen container 80 downward, and return the sealed specimen container 80 to the specimen rack 85. The controller 133 controls the opening/closing drive part 322 so as to increase the distance between the pair of hand members 321a, and release holding of the specimen container 80 by the pair of hand members 321a. After the holding is released, the transport controller 132 controls the transport device 131 so as to transport the specimen rack 85 such that a specimen container 80 to be sealed next is located at the sealing position P3.
In step S26, the residual portion RP is discarded. The controller 133 controls the horizontal drive part 334 such that the film holder 331 holding the residual portion RP of the film 75 is located at the film disposal position P13. The controller 133 controls the opening/closing drive part 332 so as to increase the distance between the first member 331a and the second member 331b, and controls the sandwiching drive part 343 so as to close the pair of sandwiching members 342. Thus, the residual portion RP of the film 75 is sandwiched by the pair of sandwiching members 342 of the film removal part 341. The controller 133 controls the up-down drive part 344 so as to move the pair of sandwiching members 342 downward to the disposal part 345. Thereafter, the controller 133 controls the sandwiching drive part 343 so as to open the pair of sandwiching members 342 which has entered the disposal part 345. Thus, the residual portion RP of the film 75 having been sandwiched by the pair of sandwiching members 342 is collected into the disposal part 345.
When all the specimen containers 80 to be sealed have been subjected to the sealing process, the specimen rack 85 is transported from the sealing unit 130 to the specimen processing unit 140 (see
For example, in
The transport device 141 of the specimen processing unit 140, by using a movable member 401, moves the received specimen rack 85 from the second transport path 141b having an inlet to the loading/storage part 141c, and further moves the specimen rack 85 from the loading/storage part 141c to the first transport path 141a. Since aspiration of the urine specimen 90 from each specimen container 80 (see
Therefore, in the sealing process of the sealing unit 130, if the specimen rack 85 enters the transport device 141 of the specimen processing unit 140, the transport device 141 cannot transport the specimen rack 85 from the second transport path 141b to the loading/storage part 141c by using the movable member 401.
In the present embodiment, the transport controller 132 of the sealing unit 130 is configured to perform control of transporting the specimen rack 85 such that the K-th and subsequent specimen holding positions from the head of the specimen rack 85 are transported to the sealing position P3, on the condition that the transport device 141 can receive the specimen rack 85. The “K-th” indicates a specimen holding position that causes the head of the specimen rack 85 to enter the inlet of the transport device 141 if the K-th specimen holding position is located at the sealing position P3. The transport controller 132 is configured to perform control of suspending transport of the K-th and subsequent specimen holding positions from the head of the specimen rack 85 to the sealing position P3 if the transport device 141 cannot receive the specimen rack 85.
The state where the transport device 141 can receive the specimen rack 85 is the state where no specimen rack 85 is placed in the loading/storage part 141c. The state where the transport device 141 cannot receive the specimen rack 85 is the state where a specimen rack 85 is placed in the loading/storage part 141c. The transport controller 132 acquires the transport state of the specimen rack 85 in the transport device 141 from the transport controller 142 of the specimen processing unit 140. The transport controller 132 inhibits transport of the K-th and subsequent specimen holding positions to the sealing position P3 when a specimen rack 85 is placed in the loading/storage part 141c of the transport device 141, and permits transport of the K-th and subsequent specimen holding positions to the sealing position P3 when no specimen rack 85 is placed in the loading/storage part 141c.
Next, the specimen processing devices included in the specimen processing unit 140 and the specimen processing unit 150 shown in
The specimen processing device 145 of the specimen processing unit 140 performs measurement related to a urine qualitative test. The urine qualitative test is a test for measuring chemical components in urine related to a laboratory test. As shown in
The measurement part 410 applies the urine specimen to the test strip, and measures color reactions on the test strip, thereby measuring test item components contained in the urine specimen. The measurement part 410 feeds out a test strip from a test strip feeder 411 in which test strips are stored, to a predetermined test position inside the measurement part 410. A specimen supply part 412 supplies a urine specimen 90 aspirated from a specimen container 80 by the aspiration tube 32, to the test strip. The measurement part 410 irradiates the test strip with measurement light emitted from a light source 413, and receives the measurement light by a color sensor 414 to measure color reactions on the test strip. Examples of measurement items include glucose, protein, bilirubin, and ph (hydrogen ion exponent).
The controller 143 of the specimen processing unit 140 controls the specimen processing device 145 such that, when the aspiration tube 32 aspirates the urine specimen 90, agitation by aspiration is performed in the specimen container 80 by using the aspiration tube 32 which has penetrated through the film 75. The agitation by aspiration is a process of agitating the urine specimen 90 through aspiration of the urine specimen 90 from the specimen container 80 and discharge of the aspirated urine specimen 90 into the specimen container 80. The agitation by aspiration can reduce leakage of the urine specimen 90 from the specimen container 80 during agitation, as compared to, for example, agitation by inversion in which the urine specimen 90 is agitated by inverting the specimen container 80. Therefore, the unpleasant feeling of the user due to odor of the urine specimen 90 can be effectively reduced.
The specimen processing device 155 of the specimen processing unit 150 performs measurement related to a urinary sediment test. The urinary sediment test is a test for measuring solid components (sediments) in urine, and classifying and counting the solid components. As shown in
The measurement part 420 includes a flow cytometer. In the measurement part 420, a sample preparation part 421 prepares a measurement sample by using a reagent such as a staining liquid, from the urine specimen 90 aspirated from the specimen container 80 by the aspiration tube 32. The controller 153 of the specimen processing unit 150 controls the specimen processing device 155 such that, when the urine specimen 90 is aspirated, agitation by aspiration is performed in the specimen container 80 by the aspiration tube 32 which has penetrated through the film 75. Then, the sample preparation part 421 supplies the measurement sample to a flow cell 422. The light source 423 irradiates the flow cell 422 with measurement light. A light receiver 424, a light receiver 425, and a light receiver 426 respectively measure forward scattered light, side scattered light, and fluorescence, of the measurement light, generated from solid components in the measurement sample that flows in the flow cell 422. An optical system 427 including a lens, a spectrometer, etc., is disposed between the flow cell 422 and each of the light source 423, the light receiver 424, the light receiver 425, and the light receiver 426. The controller 153 counts and classifies the solid components by analyzing obtained light reception signals. Examples of the solid components include red blood cells, white blood cells, epithelial cells, casts, and bacteria contained in the urine specimen 90.
The controller 143 of the specimen processing unit 140 and the controller 153 of the specimen processing unit 150 are configured to analyze data obtained from the corresponding specimen processing devices 145 and 155, respectively. An input device 431 through which the user inputs various kinds of information to the computer and a display 432 on which the computer displays various kinds of information can be connected to the I/O interface 454 of each of the controller 143 and the controller 153. The input device 431 and the display 432 may be built in the computer, or may be (externally) connected to the computer. For example, the input device 431 may be a keyboard, a mouse, a touch sensor, or the like. The display 432 is a display device such as a liquid crystal monitor. The display 432 may be a touch panel display integrated with a touch sensor as the input device 431.
With reference to
Firstly, a specimen rack 85 in which specimen containers 80 to be processed are set is placed in the loading unit 110 by the user. When the user has performed an input operation on a start button, specimen processing is started.
In step S51, a transport step for the specimen rack 85 is performed. The controller 113 of the loading unit 110 (see
In step S52, an uncapping step is performed by the uncapping unit 120. The transport controller 122 controls the transport device 121 so as to receive the specimen rack 85 from the loading unit 110 and sequentially transport the plurality specimen containers 80 in the specimen rack 85 to the uncapping position P2. During the transport of the specimen containers 80 to the uncapping position P2, the controller 123 controls the container identification part 201 (see
In step S53, a sealing step is performed by the sealing unit 130 (see
In step S54, a specimen processing step is performed by the specimen processing unit 140 and the specimen processing unit 150 (see
In the specimen processing unit 150, the transport controller 152 controls the transport device 151 so as to receive the specimen rack 85 from the specimen processing unit 140 and transport the plurality of specimen containers 80 in the specimen rack 85 from the second transport path 151b to the first transport path 151a. The transport device 151 sequentially transports the plurality of specimen containers 80 in the specimen rack 85 to the reading position P6, and thereafter sequentially transports the specimen containers 80 to the aspiration position P7. The controller 153 controls the information reader 154 so as to read the identification information attached to each specimen container 80 at the reading position P6. On the basis of the read identification information, the controller 153 acquires, from the host computer 500, a measurement order for the urine specimen 90 contained in each specimen container 80. As for a specimen container 80 that is set as a test target according to the measurement order, the controller 153 causes the aspiration tube 32 to sequentially aspirate the urine specimen 90 from the specimen container 80 at the aspiration position P7. The controller 153 controls the specimen processing device 155 so as to perform a specimen measurement operation, and analyzes measurement data obtained from the specimen processing device 155. The transport controller 152 controls the transport device 151 so as to transport the specimen rack 85 for which aspiration has been completed, from the first transport path 151a to the second transport path 151b, and transport the specimen rack 85 from the second transport path 151b to the second sealing unit 160.
The specimen processing unit 150 performs specimen measurement not only when an order of a urinary sediment test has been registered in advance but also when an order of a urinary sediment test is registered on the basis of an analysis result of a urine qualitative test performed by the upstream-side specimen processing unit 140. The controller 153 controls the operation of the specimen processing device 155 such that specimen aspiration is not performed on a specimen container 80 for which specimen processing (urinary sediment test) by the specimen processing unit 150 is not required according to measurement order information.
In step S55, a re-sealing step is performed by the second sealing unit 160. The transport controller 162 controls the transport device 161 so as to receive the specimen rack 85 from the specimen processing unit 150, and sequentially transport the plurality of specimen containers 80 in the specimen rack 85 to the sealing position P8.
In the present embodiment, the step of re-sealing a specimen container 80 is selectively performed on the basis of identification information. That is, the controller 163 acquires identification information having been read by at least one of the information reader 114, the information reader 144, and the information reader 154 through inter-device communication, and individually identifies the specimen containers 80 in the specimen rack 85. The controller 163 is configured to control the second sealing unit 160 so as to selectively perform re-sealing on the specimen containers 80 on the basis of the read identification information.
Thus, sealing of the specimen containers 80 can be selectively performed in accordance with difference in processes to be performed on the urine specimens 90 having been subjected to specimen processing. For example, re-sealing is performed on a specimen container 80 whose urine specimen 90 is planned to be preserved or transferred to another department, while re-sealing is not performed on a specimen container 80 whose urine specimen 90 is to be discarded.
The controller 163 acquires, from the host computer 500, information related to a process for a urine specimen 90 on the basis of identification information of the urine specimen 90. For example, the controller 163 selects to perform re-sealing on a specimen container 80 that contains a urine specimen 90 to be preserved or transferred to another test department. For example, the controller 163 selects not to perform re-sealing on a specimen container 80 that contains a urine specimen 90 to be discarded.
The controller 163 controls the sealing mechanism (sealing device 300) so as to perform the sealing process at the sealing position P8. The transport controller 162 controls the transport device 161 so as to transport the specimen rack 85 to the collection unit 170 when the specimen containers 80 to be re-sealed, set in the specimen rack 85, have been subjected to the sealing process.
In step S56, a collection step for the specimen rack 85 is performed. The transport controller 172 of the collection unit 170 controls the transport device 171 so as to receive the specimen rack 85 from the second sealing unit 160, and transport the received specimen rack 85 to the storage position.
Thus, execution of the specimen processing method by the specimen processing system 100 is completed for one specimen rack 85. When the user sets a plurality of specimen racks 85 in the loading unit 110, the aforementioned steps are sequentially performed for each of the specimen racks 85.
The specimen rack 85 transported to the storage position is collected by the user. The urine specimens 90 having been analyzed and collected are subjected to post-processing such as disposal or preservation, according to the test results or circumstances. For example, the user judges whether or not a specimen container 80 having been subjected to specimen analysis needs to be preserved for a retest or an additional test. A specimen container 80 whose urine specimen need not be preserved is transported to a disposal place and discarded by a predetermined method. A specimen container 80 whose urine specimen needs to be preserved for a predetermined period or transported to another department is preserved for the predetermined period at a predetermined place under a predetermined environment (refrigerating storage, or room-temperature storage in some cases). The user re-loads the preserved specimen container 80 to the specimen processing system 100 at a desired timing to perform a retest. Alternatively, the preserved specimen container 80 is subjected to another test in another test system. If abnormality is detected in a urine specimen 90 as a result of the analysis, this urine specimen 90 may be subjected to a bacteriological test for diagnosis of urinary tract infection.
It should be noted that the embodiment disclosed herein is merely illustrative in all aspects and should not be considered as being restrictive. The scope of the present disclosure is not defined by the description of the above embodiment but by the scope of the claims, and further includes meaning equivalent to the scope of the claims and all changes (modifications) within the scope of the claims.
For example, in the embodiment described above, one loading unit 110 is disposed. However, a plurality of loading units 110 may be disposed. In the loading unit 110, all the specimen containers 80 have the caps 84 attached thereto. However, specimen containers 80 having caps 84 and specimen containers 80 having no caps 84 may coexist.
For example, in an example shown in
In the above configuration, when a specimen container 80 to be sealed and a specimen container 80 not to be sealed are present, the specimen container 80 to be sealed can be set in the first loading unit 601 while the specimen container 80 not to be sealed can be set in the second loading unit 603. The specimen container 80 set in the first loading unit 601 can be sealed by the sealing unit 602 while the specimen container 80 set in the second loading unit 603 can be transported not through the sealing unit 602, whereby specimen processing can be efficiently performed.
In examples shown in
In the configuration shown in
In the configuration examples shown in
In an example shown in
Thus, specimen processing using one or a plurality of specimen processing units 622 can be performed for one specimen container 80. Since the plurality of second sealing units 623 are disposed, a specimen container 80 having been subjected to specimen processing in any of the specimen processing units 622 can be re-sealed by any of the second sealing units 623, whereby odor of the urine specimen 90 released from the specimen container 80 can be reduced.
Although the configuration example of the above embodiment includes the uncapping unit 120, the uncapping unit 120 may be dispensed with as shown in
In the above embodiment, an opening 81 of a specimen container 80 is sealed with a film 75 through which the aspiration tube 32 can penetrate, before the specimen is aspirated by the aspiration tube 32 in the specimen processing device 145. However, the present disclosure is not limited thereto. In
A third specimen processing method of the present embodiment is a method of processing a urine specimen 90 contained in a specimen container 80 having an opening 81 by using a specimen processing device 31 as shown in
In
The step (2) of performing the specimen processing on the aspirated urine specimen 90 is performed by the specimen processing device 31. The processing performed by the specimen processing device 31 is not particularly limited but can be specimen measurement similar to that of the above embodiment.
In the step (3) of sealing the opening 81 of the specimen container 80, from which the urine specimen 90 has been aspirated, with the seal 71 through which the aspiration tube 32 can penetrate, the opening 81 of the specimen container 80 is sealed with the seal 71 for the first time. The sealing process can be performed by the sealing unit 10. The specimen container 80 having been subjected to specimen processing and sealed is subjected to post-processing such as disposal or preservation according to the test results, circumstances, or the like as described above.
According to the third specimen processing method, since the opening 81 is sealed with the seal 71 after aspiration of the urine specimen 90, release of odor from the specimen container 80 can be reduced while the urine specimen 90 is preserved for a retest or the like. When the specimen container 80 sealed with the seal 71 is again subjected to specimen processing for a retest or the like, the aspiration tube 32 can penetrate through the seal 71 and aspirate the urine specimen 90, which makes an uncapping operation unnecessary. Therefore, complication of uncapping and capping operations can be reduced. Moreover, even when an uncapping operation is performed on a specimen container 80 sealed with a cap, the removed cap need not be stored for recapping, thereby reducing complication of uncapping and capping operations.
In the above embodiment, only one example has been described for the sealing method by the sealing device 300. However, the specimen processing method of the present disclosure is not limited thereto, and a sealing method to be performed may be selected from among a plurality of sealing methods in the step of sealing a specimen container with a seal.
Thus, sealing of each specimen container 80 can be performed by a more appropriate sealing method. For example, different sealing methods can be selected according to the specimen type, whether it is a first test or a retest, the content of specimen processing, whether or not preservation is required, the transport destinations, or the like. For example, as for a specimen container 80 to be subjected to agitation by inversion, a sealing method capable of more reliable sealing can be selected. Moreover, different sealing patterns make it possible to discriminate specimen containers 80 by the appearances of the seals 71.
In the above embodiment, the sealing method shown in
With reference to
(A) With a film 75 being held by the film holder 331, an upper end portion of a specimen container 80 is pressed against the film 75 from below via the through-hole 331c of the first member 331a. The film 75 is adhered to the opening edge and the opening 81 is covered with the film 75.
(B) The film holder 331 is rotated at a rotation angle of about 240°. The film 75 is wound around the outer peripheral surface of the specimen container 80.
(C) With the distance between the first member 331a and the second member 331b of the film holder 331 being increased, the film holder 331 is rotated at a rotation angle of about 120°. The film 75, which has been sandwiched and adhered to the lower first member 331a, is removed from the first member 331a.
(D) The specimen container 80 held by the container holder 321 is moved downward. The specimen container 80 is moved downward until an outer peripheral portion of the film 75 is left on the first member 331a and a portion, of the film 75, inside the outer peripheral portion is placed in the through-hole 331c of the first member 331a.
(E) The distance between the first member 331a and the second member 331b is reduced, and the outer peripheral portion of the film 75 present on the first member 331a is sandwiched by the first member 331a and the second member 331b. Thus, in the second sealing method, the portion, of the film 75, held by the film holder 331 is changed during sealing.
(F) The film holder 331 is rotated at a rotation angle of about 240°. The film 75 is wound upward such that it is folded back upward from a lower end of the portion already wound around the specimen container 80 through the first rotation, and is superposed on the already wound portion. On the upper side of the upper end portion of the specimen container 80, a residual portion, of the film 75, which is not wound around the specimen container 80 is twisted and bundled immediately above the opening 81.
(G) With the distance between the first member 331a and the second member 331b of the film holder 331 being increased, the film holder 331 is rotated at a rotation angle of about 120°. The outer peripheral portion, of the film 75, which has been adhered to the lower first member 331a is removed from the first member 331a.
(H) The specimen container 80 held by the container holder 321 is moved downward, and the specimen container 80 is returned to the specimen rack 85. At this time, a bundle BD, of the residual portion of the film 75, which is formed by the rotation passes through the through-hole 331c of the first member 331a, whereby the bundle BD of the residual portion is shaped such that it does not spread in the horizontal direction but rises upward from the specimen container 80. Thereafter, holding of the specimen container 80 by the container holder 321 is released.
For example, in the re-sealing process shown in step S55 in
In the above embodiment, in the sealing device 300, the rotation drive part 333 rotates the film holder 331. However, the rotation drive part 333 may rotate the container holder 321, or the rotation drive part 333 may rotate both the film holder 331 and the container holder 321.
In the above embodiment, in the sealing device 300, the rotation drive part 333 is operated until the film 75 wound around the specimen container 80 is separated from the portion of the film 75 held by the film holder 331, whereby the portion of the film 75 wound around the specimen container 80 is separated from the residual portion RP of the film 75. However, the present disclosure is not limited thereto. The film 75 wound around the specimen container 80 may be left as it is. That is, after the film 75 has been wound around the specimen container 80 as shown in
In the above embodiment, the up-down drive part 323 drives the container holder 321 in the up-down direction. However, the up-down drive part 323 may drive the film holder 331 in the up-down direction, or may drive both the container holder 321 and the film holder 331 in the up-down direction.
In the above embodiment, the cutter mechanism 312 separates the film 75 from the film roll FR. However, the present disclosure is not limited thereto. Instead of the cutter mechanism 312, the following configuration may be adopted. That is, lines of perforations (continuous small holes which transverse the film 75) are formed in the film 75 at regular intervals. After the film 75 is sandwiched by the film holder 331, the film holder 331 is rotated to apply horizontal force to the film 75, thereby cutting the film 75 along the perforations.
In the above embodiment, a specimen container 80 is held by the container holder 321. However, the present disclosure is not limited thereto. For example, when the sealing device 300 is configured as a single device, the user may manually hold a specimen container 80 to be sealed, instead of the container holder 321.
In the above embodiment, the film 75 is wound around a specimen container 80 by relatively rotating the film 75 and the specimen container 80 with the film 75 being in contact with the opening edge of the specimen container 80. However, the present disclosure is not limited thereto. As shown in
In the above embodiment, the film holder 331 sandwiches the film 75 by using the first member 331a and the second member 331b. However, the present disclosure is not limited thereto. As shown in
In the above embodiment, the protruding pressing part 335 disposed in the film holder 331 pushes the film 75 into an opening 81 of a specimen container 80. However, the present disclosure is not limited thereto. As shown in
In the above embodiment, the specimen containers 80 are subjected to the sealing process one by one. However, the present disclosure is not limited thereto. The openings 81 of a plurality of specimen containers 80 may be collectively sealed through one sealing process. In the example of
In the above embodiment, the seal (second seal) is the film 75. However, the present disclosure is not limited thereto. The seal may have a cap-like structure in which, for example, an upper end surface of an annular peripheral wall member formed of a hard resin or the like is covered with a film or a thin member through which the aspiration tube 32 can penetrate.
The specimen containers 80 shown in
In the example of
In the above embodiment, the specimen processing system 100 including two specimen processing units, i.e., the specimen processing unit 140 and the specimen processing unit 150, has been described. However, the specimen processing system 100 may include one specimen processing unit as shown in
In the above embodiment, the transport device 20 (transport devices 111 to 171) transports the specimen rack 85 holding the specimen containers 80. However, the present disclosure is not limited thereto. The transport device 20 may directly transport the specimen containers 80 one by one without using the specimen rack 85.
In the above embodiment, the transport device 20 (transport devices 111 to 171) is configured to be able to transport the specimen rack 85 holding the specimen containers 80 from the loading unit 110 to the collection unit 170. However, the present disclosure is not limited thereto. In the present disclosure, the transport device 20 may be configured to be able to transport the specimen rack 85 between some of the units.
In the above embodiment, the specimen containers 80 are transported by the transport device 20. However, an operator may manually transport a specimen container 80 to the position of the sealing device 300 (sealing unit 10) or the position of the aspiration tube 32 of the specimen processing device. For example, in a case where a specimen processing unit and a sealing unit are not connected to each other but are installed as separate and independent devices, the operator may transport a specimen container 80 to a sealing device for a sealing process, and may transport the sealed specimen container 80 to the specimen processing unit for specimen aspiration and specimen processing.
In the above embodiment, the aspiration tube 32 of the specimen processing device penetrates through the seal (film 75). However, the present disclosure is not limited thereto. In the present disclosure, a puncture member for forming a through-hole TH may be provided separately from the aspiration tube 32, and this puncture member may penetrate through the seal (film).
That is, a fourth specimen processing method of the present embodiment is a method of processing a urine specimen 90 contained in a specimen container 80 having an opening 81, by using a specimen processing device. The method includes (1) a step of sealing, with a seal, the opening 81 of the specimen container 80 containing the urine specimen 90, (2) a step of forming, by using a puncture member of the specimen processing device, a through-hole TH in the seal with which the specimen container is sealed, (3) a step of aspirating, by using an aspiration tube 32, the urine specimen 90 in the specimen container 80 via the through-hole TH, and (4) a step of performing specimen processing on the aspirated urine specimen 90.
As the puncture member, a known needle member may be used. The puncture member forms the through-hole TH in a part of the seal, and the aspiration tube 32 is inserted into the specimen container 80 through the through-hole TH, whereby the urine specimen 90 is aspirated. The outer diameter (diameter) of the puncture member may be sufficiently smaller than the inner diameter of the opening 81 because the through-hole TH is only required to let the aspiration tube 32 pass through it.
Thus, the urine specimen 90 can be aspirated through the through-hole TH while the opening 81 of the specimen container 80 is sealed with the seal. Therefore, release of odor can be reduced when the urine specimen 90 is aspirated during the specimen processing. After aspiration of the urine specimen 90, the through-hole TH is left in a part of the seal. However, since the through-hole TH formed in the seal is sufficiently smaller than the opening 81 of the specimen container 80, release of odor can be effectively reduced as compared to the case where the opening 81 is fully opened.
