The present invention relates to an organism sample measurement sensor, such as a blood sugar level sensor, and a housing container that houses the same.
A configuration of a conventional organism sample measurement sensor, such as a blood sugar level sensor, is as follows.
That is, as shown in
However, the conventional organism sample measurement sensor and the housing container that houses the same have very low convenience.
That is, blood sugar level sensor 101 as the conventional organism sample measurement sensor has sensor body 102 having a long plate shape, and as described above, a plurality of blood sugar level sensors 101 are housed in the housing container having a bottomed cylindrical shape (not shown) to be overlapped and in close contact with each other. It is difficult to draw blood sugar level sensors 101 that are overlapped and in close contact with each other out of the housing container one by one. Sometimes, a plurality of blood sugar level sensors 101 can be taken out to drop one or more of them.
Consequently, a user needs to slowly and carefully draw one blood sugar level sensor 101 out of the housing container. As a result, blood sugar level sensor 101 as the organism sample measurement sensor cannot be easily taken out of the housing container.
Accordingly, an object of the present invention is to easily take an organism sample measurement sensor out of a housing container.
PTL 1: Unexamined Japanese Patent Publication No. 2010-173674
The present invention is provided with a sensor body having a long plate shape, a measurement part provided in a front end section of the sensor body, a connection terminal provided in a rear end section of the sensor body, and a connection part electrically connecting the measurement part and the connection terminal in the sensor body. Close contact prevention parts having the same plate shape are provided in the same position of both a front surface and a back surface of the sensor body, the position not overlapping with a position of a center of gravity of the sensor body, the measurement part, and the connection terminal. A length in a longitudinal direction of the sensor body of the close contact prevention parts is shorter than a length thereof orthogonal to the longitudinal direction.
This can easily take a sensor out of the housing container.
That is, in the present invention, the close contact prevention parts having substantially the same shape adhere into the same position of both the front surface and the back surface of the sensor body. Therefore, a plurality of blood sugar level sensors cannot come into close contact with each other in a housing container, and can be individually separated.
In addition, the close contact prevention parts are provided on the sensor body between the position of the center of gravity of the sensor body and the measurement part (that is, on a measurement part side). The sensor body is housed in the housing container so that the measurement part side is located toward an opening side of the housing container. Therefore, the close contact prevention parts on the sensor body are arranged near an opening in a top surface of the housing container.
Therefore, a user can insert e.g., his/her forefinger from the opening of the housing container to abut the inserted forefinger onto the close contact prevention parts near the opening.
As a result, only one of the individually separated sensors can be easily taken out of the housing container.
Hereinafter, an organism sample measurement sensor according to a first exemplary embodiment of the present invention applied to a blood sugar level sensor measuring a blood sugar level will be described with reference to the accompanying drawings.
As shown in
As shown in
That is, as is well known, blood spotted onto measurement part 3 reacts with reagent 9 to change a terminal current of connection terminals 4 according to a blood sugar level in the blood. The terminal current corresponding to the blood sugar level is transmitted to a measurement device (not shown) via connection part 5 and connection terminal 4.
As shown in
As shown in
A thickness of close contact prevention parts 10, that is, a thickness vertical to a surface of sensor body 2, is smaller than a thickness of sensor body 2 (e.g., 0.5 mm). More specifically, the thickness of close contact prevention parts 10 is substantially the same as a thickness of cover 8, and is approximately one-third of the thickness of sensor body 2. Since the thickness of close contact prevention parts 10 is smaller than the thickness of sensor body 2, as shown in
In this exemplary embodiment, close contact prevention parts 10 configured by plate-like bodies having substantially the same rectangular shape adhere into the same position of both the front surface and the back surface of sensor body 2. Therefore, sensor bodies 2 cannot come into close contact with each other in housing container body 12, so that a plurality of blood sugar level sensors 1 can be individually separated.
At this time, it is important that close contact prevention parts 10 having a rectangular shape be provided on both the front surface and the back surface of sensor body 2. For instance, when close contact prevention parts 10 are provided only on the front surfaces of sensor bodies 2 to abut the back surfaces of sensor bodies 2 onto each other, the entire back surfaces thereof come into close contact with each other to be difficult to be separated.
On the contrary, in this exemplary embodiment, close contact prevention parts 10 are provided on both the front surface and the back surface of sensor body 2. Therefore, even when the front surfaces or the back surfaces of sensor bodies 2 are abutted onto each other, sensor bodies 2 cannot come into close contact with each other in housing container body 12, so that blood sugar level sensors 1 can be individually separated.
As a result, a user can draw only one of individually separated blood sugar level sensors 1 out of housing container body 12 very easily.
This drawing-out will be specifically described. As shown in
Therefore, the user can insert e.g., his/her forefinger from the opening of housing container body 12 to abut the inserted forefinger onto close contact prevention parts 10 near the opening.
Here, the length in the longitudinal direction of sensor body 2 of close contact prevention parts 10 is shorter. Since close contact prevention parts 10 are made smaller, the user lightly presses close contact prevention parts 10 in a direction of an inner wall surface of housing container body 12 with a cushion of the inserted forefinger to reliably catch close contact prevention parts 10. In addition, adjacent close contact prevention parts 10 that are made smaller can be prevented from coming into close contact with each other.
When sensor body 2 is moved by moving the forefinger from this state to the opening side of housing container body 12, each of individually separated blood sugar level sensors 1 can be drawn out of housing container body 12.
In addition, close contact prevention parts 10 are provided from end to end in the lateral direction of sensor body 2. Therefore, the user can draw out sensor body 2 by catching an end section on a connection terminal 4 side of either of close contact prevention parts 10 with the cushion of the inserted forefinger. The drawing-out ability of sensor body 2 can thus be enhanced.
As a result, the user can take one blood sugar level sensor 1 out of housing container body 12 very easily.
Such blood sugar level sensor 1 has been made smaller in recent years. Therefore, when blood sugar level sensor 1 is taken out of housing container body 12 to be set in the measurement device (not shown), blood sugar level sensor 1 can be accidentally dropped.
Accordingly, as shown in
Therefore, for instance, sensor body 2 that is accidentally dropped onto a desk makes a line contact with a surface of the desk at connection terminal 4 and the end section on the connection terminal 4 side of either of close contact prevention parts 10. Then, by the line contact at two locations, sensor body 2 is tiltably held with respect to the surface of the desk. Therefore, sensor body 2 cannot come into close contact with the top surface of the desk.
To house a maximum number of blood sugar level sensors 1 in housing container 11, the thickness of close contact prevention parts 10 is smaller than the thickness of sensor body 2. This makes a gap between dropped sensor body 2 and the surface of the desk smaller, so that sensor body 2 is difficult to be taken up. Accordingly, in this exemplary embodiment, the line contact at two locations tiltably holds dropped sensor body 2 to forcefully lift an end section on the measurement part 3 side of sensor body 2.
By this lifting, the gap between the end section on the measurement part 3 side of sensor body 2 and the surface onto which sensor body 2 is dropped becomes larger. Therefore, the user can hold sensor body 2 between e.g., his/her fingers in the gap to easily take up sensor body 2.
At this time, since sensor body 2 only makes a line contact with the surface of the desk at two locations, the user can easily slide and move sensor body 2 to a place appropriate for taking up sensor body 2. Since close contact prevention parts 10 are provided on the front surface and the back surface of sensor body 2, even when either of the front surface and the back surface of dropped sensor body 2 is directed downward, blood sugar level sensor 1 can be handled in the same manner.
As a result, blood sugar level sensor 1 can be easily handled even after blood sugar level sensor 1 is taken out of housing container 11.
Further, opposite surfaces of close contact prevention parts 10 of this exemplary embodiment of surfaces thereof adhering onto sensor body 2, that is, surfaces thereof onto which the forefinger of the user is abutted, are rough surfaces. Therefore, the user can reliably catch the rough surfaces of close contact prevention parts 10 with the cushion of the inserted forefinger.
In the above description, close contact prevention parts 10 are configured by rectangular plate-like bodies, but, in place of that, close contact prevention parts 10 may be configured by printing. More specifically, even when close contact prevention parts 10 are configured by screen printing with silica gel in the same position on the front surface and the back surface of sensor body 2 on the measurement part 3 side between measurement part 3 and connection terminal 4, one blood sugar level sensor 1 can be drawn out of housing container body 12 very easily.
That is, by swelled printing ink, the front surfaces and the back surfaces of adjacent blood sugar level sensors 1 in which close contact prevention parts 10 are configured on the front surfaces and the back surfaces of sensor bodies 2 by screen printing can be prevented from coming into close contact with each other. Therefore, one blood sugar level sensor 1 can be easily taken out of housing container body 12.
When close contact prevention parts 10 are configured by screen printing with silica gel that is an example of a moisture absorber, measurement accuracy of blood sugar level sensor 1 can be prevented from being varied.
That is, measurement part 3 of blood sugar level sensor 1 reacts blood with the reagent to measure a blood sugar level, but moisture in air also reacts with the reagent. Consequently, when moisture prevention is insufficient at the time of housing blood sugar level sensor 1 in housing container 11, the measurement accuracy of blood sugar level sensor 1 can be varied.
Accordingly, in this exemplary embodiment, close contact prevention parts are configured by screen printing with silica gel, and to prevent moisture, close contact prevention parts 10 configured on blood sugar level sensor 1 by screen printing with silica gel absorb moisture in sealed housing container 11 that houses blood sugar level sensor 1.
As a result, the measurement accuracy of blood sugar level sensor 1 as the organism sample measurement sensor according to this exemplary embodiment can be prevented from being varied, and one blood sugar level sensor 1 can be taken out of housing container body 12 very easily.
In the first exemplary embodiment of the present invention, the user inserts the forefinger into housing container 11 to take out blood sugar level sensor 1. In the second exemplary embodiment of the present invention, blood sugar level sensor 1 in housing container 11 is shakingly taken out.
As shown in
Specifically, close contact prevention parts 10a configured by plate-like bodies are provided in a position between a position of a center of gravity of sensor body 2 and connection terminal 4, the position not overlapping with the position of the center of gravity of sensor body 2 and connection terminal 4. That is, as shown in
A housing container suitable for blood sugar level sensor 14 will be described below in detail.
As shown in
Shaking-out member 18 shaking out blood sugar level sensor 14 has elastic top plate 20 made of rubber as an example of an elastic body, mounted in the opening of container body 15, and having shaking-out side 19 on an outer peripheral section thereof, and a guide wall 21 opposite to shaking-out side 19 of elastic top plate 20 and hung downward from the opposite section.
Elastic top plate 20 has a substantially circular shape according to the shape of the opening of the top surface of container body 15. As shown in
As shown in
More specifically, short side shaking-out width H of shaking-out opening 22 is 1.3 times larger than the plate thickness of one sensor body 2, and close contact prevention parts thickness T of sensor body 2 is 1.6 times larger than the plate thickness of one sensor body 2. Thus, close contact prevention parts 10a on sensor body 2 can be caught into shaking-out opening 22, which will be described later in detail.
Close contact prevention parts thickness T of sensor body 2 is smaller than the plate thickness of two sensor bodies 2. More specifically, as described above, close contact prevention parts thickness T is 1.6 times larger than the plate thickness of one sensor body 2, and is smaller than the plate thickness of two sensor bodies 2. That is, close contact prevention parts thickness T is smaller to house a large number of blood sugar level sensors 14 in container body 15.
As shown in
Further, both end sections in the longitudinal direction of guide wall 21 are abutted onto inner wall surfaces of container body 15. Therefore, vibration of guide wall 21 in container body 15 due to vibration of shaken-out blood sugar level sensor 14 can be prevented.
Guide wall 21 is provided with holding part 23 holding elastic top plate 20. Elastic top plate 20 adheres onto holding part 23 with e.g., a double-faced tape near the outer peripheral section thereof on the opposite side of shaking-out side 19. Therefore, shaking-out side 19 of elastic top plate 20 is elastically held in an axial direction of container body 15 about the adhering portion.
As shown in
Then, when the user closes lid 16, lid 16 that covers elastic top plate 20 of shaking-out member 18 covers the opening in the top surface of container body 15. In this state, the user conveys container body 15 to an examining place.
An operation of the above configuration will be described below.
That is, as shown in
In this exemplary embodiment, close contact prevention parts 10a configured by plate-like bodies are provided in the same position of the front surface and the back surface on a connection terminal 4 side from a center in a longitudinal direction of sensor body 2, and close contact prevention parts 10a provided on the front surface and the back surface of sensor body 2 have substantially the same shape.
Therefore, in a state where a plurality of blood sugar level sensors 14 are housed in container body 15, close contact prevention parts 10a are present in the same position between overlapped blood sugar level sensors 14, so that sensor bodies 2 of blood sugar level sensors 14 can be prevented from coming into close contact with each other.
At this time, it is important that close contact prevention parts 10a configured by rectangular parallelepiped plate-like bodies be provided on both the front surface and the back surface of sensor body 2.
That is, for instance, when close contact prevention parts 10a are provided only on the front surfaces of sensor bodies 2 to abut the back surfaces of sensor bodies 2 onto each other, the back surfaces come into close contact with each other to be difficult to be separated. However, in this exemplary embodiment, close contact prevention parts 10a are provided on both the front surface and the back surface of sensor body 2.
Therefore, even when the front surfaces or the back surfaces of sensor bodies 2 of a plurality of blood sugar level sensors 14 are abutted onto each other, sensor bodies 2 cannot come into close contact with each other and can be easily individually separated.
Blood sugar level sensor 14 in
As described above, in blood sugar level sensor 14 of this exemplary embodiment, close contact prevention parts 10a are provided in the position between the position of the center of gravity of sensor body 2 and connection terminal 4, the position not overlapping with the position of the center of gravity of sensor body 2 and connection terminal 4. Therefore, in a state where blood sugar level sensor 14 is laid sideways, a measurement part 3 side of blood sugar level sensor 14 is lowered toward shaking-out opening 22.
As shown in
As described above, in this exemplary embodiment, short side shaking-out width H of shaking-out opening 22 that is horizontally long is larger than the plate thickness of one sensor body 2, and is smaller than the plate thickness of two sensor bodies 2. Therefore, two overlapped sensor bodies 2 cannot enter shaking-out opening 22, so that only the lowest one of stacked blood sugar level sensors 14 can be taken out of container body 15.
As described above, in this exemplary embodiment, close contact prevention parts 10a can prevent sensor bodies 2 from coming into close contact with each other and can be easily separated. Therefore, only the lowest blood sugar level sensor 14 can easily enter shaking-out opening 22.
As a result, as shown in
As shown in
Therefore, the end sections on the measurement part 3 side of close contact prevention parts 10a are caught onto elastic top plate 20 in shaking-out opening 22. That is, close contact prevention parts 10a configured by plate-like bodies function as stoppers. As a result, blood sugar level sensor 14 becomes stationary in a state where measurement part 3 of sensor body 2 is projected out of container body 15 from shaking-out opening 22.
The user draws stationary sensor body 2 out of container body 15.
In this exemplary embodiment, elastic top plate 20 adheres onto holding part 23 with e.g., a double-faced tape near the outer peripheral section thereof on the opposite side of shaking-out side 19. Therefore, shaking-out side 19 of elastic top plate 20 is elastically held in the longitudinal direction of container body 15 about the adhering portion.
When the user draws blood sugar level sensor 14 out of container body 15, elastic top plate 20 is pushed by close contact prevention parts 10a to be slightly warped out of container body 15, so that sensor body 2 can be drawn out of container body 15.
As a result, the user can take one blood sugar level sensor 14 out of container body 15 very easily.
As shown in
Therefore, the user may draw out one of sensor bodies 2 that can be drawn out most easily. In this respect, a plurality of blood sugar level sensors 14 can be easily taken out of shaking-out opening 22 one by one.
In this exemplary embodiment, even last blood sugar level sensor 14 can be easily taken out. That is, conventionally, for instance, since the sensor body of last blood sugar level sensor that is shaken out of the container body does not have close contact resistance with respect to other sensor bodies, the sensor body can be vigorously jumped out of the container body.
However, as described above, in this exemplary embodiment, close contact prevention parts 10a are provided on sensor body 2. Therefore, close contact prevention parts 10a are caught onto elastic top plate 20 in shaking-out opening 22, so that sensor body 2 of blood sugar level sensor 14 is projected halfway out of container body 15 to be stationary. Therefore, even last blood sugar level sensor 14 cannot be jumped out of container body 15.
As a result, even last blood sugar level sensor 14 can be taken out of container body 15 very easily.
As described above, for instance, the present invention can be widely used as the organism sample sensor, such as the blood sugar level sensor, and the housing container that houses the same.
