This application claims priority to Japanese Patent Applications Nos. 2013-195673 and 2013-235702, the disclosures of which are incorporated herein by reference in their entirety.
The present invention relates to a detecting device that is used for checking whether a drug has been discharged from a package with the drug housed therein.
It is required to provide optimal conditions, such as the dose of the drugs taken by the patient, and the dosing time (hereinafter referred also to drug taking conditions) in order to provide expected effects of the drugs prescribed to the patient. Therefore, it is desirable to manage the information on whether the patient has taken the drugs under the optimal dosing conditions (hereinafter referred also to drug taking information).
For managing the drug taking information, a detecting device, which electrically detects that a drug has been taken out of a package with the drug packed therein (a blister pack or the like, for example), is used (see Patent Literature 1). Specifically, the package includes a body that includes a housing part for housing a drug, and an aluminum foil that is attached to the body to close the housing part. The aluminum foil is provided with an electrically-conductive wire. The detecting device is electrically connectable to the conductive wire provided in the aluminum foil of the package. With this, the detecting device is configured to detect the current flowing state of the conductive wire. Specifically, when a drug is taken out of the package, the aluminum foil is torn while the conductive wire is cut, thereby causing a change in current flowing state of the conductive wire, and hence enabling the detection device to detect such a change. The detected information (date and time at which a change in current flowing state of the conductive wire has occurred, for example) is recorded and checked so that the drug taking information can be managed.
According to the detecting device described above, an end portion of the package is inserted into a groove formed in the detecting device to electrically connect the detecting device to the conductive wire of the package within the groove. Since the detecting device is used in a state where it is attached to a package such as a blister pack, the detecting device having a smallest possible size is preferable. Such a detecting device makes it difficult to have the end portion of the package inserted into the groove of the detecting device. Therefore, it is difficult to attach the detecting device to the package provided with the conductive wire. In addition, when the end portion of the package is inserted into the groove of the detecting device, the end portion may contact the detecting device and break, which results in incomplete electrical connection between the conductive wire of the package and the detecting device.

An object of the present invention is to provide a detecting device that is capable of being easily attached to a conductive-wire mounted package provided with a conductive wire that allows for electric current to flow to the package with a drug housed therein, and ensuring the electrical connection to the conductive wire.
According to the present invention, there is provided a detecting device electrically connectable to a conductive wire of a conductive-wire mounted package provided with the conductive wire that allows for electric current to flow to the package with a drug housed therein to detect a change in current flowing state of the conductive wire which is cut along with discharging of the drug from the conductive-wire mounted package, the detecting device including:
a holding part configured to hold therein the conductive-wire mounted package and electrically connectable to the conductive wire;
the holding part including a pair of holding pieces that are movable toward and away from each other, and a positioning structure that is provided in at least one of the pair of holding pieces to position the conductive-wire mounted package relative to the holding part, wherein the conductive wire and the holding part are held into an attached state where both are electrically connected to each other by holding in the holding part the conductive-wire mounted package which has been positioned by the positioning structure;
the positioning structure including at least one of a positioning recess and a positioning projection that are recessed and projected from a surface of at least one of the holding pieces that abuts the conductive-wire mounted package;
the positioning recess being configured to be brought into projection and recess fitting with a fitting projection that is formed in the conductive-wire mounted package to be insertable into the positioning recess; and
the positioning projection being configured to be brought into projection and recess fitting with a receiving recess that is formed in the conductive-wire mounted package to be capable of receiving the positioning projection.
According to the above configuration, since the pair of holding pieces are movable toward and away from each other, the distance between the pair of holding pieces are increased by moving the pair of holding pieces away from each other. Whereby, the conductive-wire mounted package can be easily placed between the pair of holding pieces. Thus, attaching the detecting device to the conductive-wire mounted package (electrical connection between the conductive wire and the detecting device) can be easily achieved.
In addition, provision of the positioning structure enables determination of the positional relation of the conductive-wire mounted package relative to the holding part (specifically, the pair of holding pieces). Thus, electrical connection between the conductive wire and the detecting device can be ensured. Further, since the conductive-wire mounted package can be held in the holding part (specifically, sandwiched by the pair of holding pieces), the attached state of the conductive-wire mounted package to the detective device can be securely maintained.
The positioning structure is composed of at least one of a positioning recess and a positioning projection that is formed in at least one of the holding pieces. With this, when the conductive-wire mounted package is held in the detecting device, the conductive-wire mounted package is brought into projection and recess fitting with the positioning recess and/or the positioning projection. Thus, the positional relation between the detecting device and the conductive-wire mounted package can be securely determined, and electrical connection between the conductive-wire mounted package and the detecting device can be easily achieved.
The detecting device is preferably configured so that the conductive-wire mounted package is composed of a sheet shaped label provided with a conductive wire and a package to which the label is bonded, the label includes a connection part that is electrically connected to the holding part, the package includes a detachable area that is formed to cover the connection part and is detachable, and the holding part is is electrically connectable to the connection part of the label, the connection part being exposed through the cutout part formed by detaching the detachable area from the package.
According to the above configuration, in a state before the detecting device is attached to the conductive-wire mounted package, the connection part of the label is covered by the detachable area of the package. Therefore, it is possible to prevent dust or moisture from adhering to the connection part, or the connection part from being broken. That is, the connection part is protectable by the detachable area. On the other hand, the connection part of the label is exposed through the cutout part by detaching the detachable area from the package (that is, by forming the cutout part). Therefore, the electrical connection between the holding part and the connection part can be easily achieved.
Thus, according to the present invention, it is possible to provide a detecting device that is capable of being easily attached to the conductive-wire mounted package provided with a conductive wire that allows for electric current to flow to the package with a drug housed therein, and ensuring the electrical connection to the conductive wire.
An embodiment of the present invention is hereinafter described with reference to
A detecting device according to the present invention is configured to detect that a drug has been discharged from a package with the drug packed therein. Specifically, the detecting device is electrically connectable to a conductive-wire mounted package provided with a conductive wire that allows for electric current to flow to the package. Whereby, the detecting device is configured to detect a change in current flowing state of the conductive wire. Because of this, the description is made for the conductive-wire mounted package corresponding to the detecting device, prior to the description for the detecting device of the present invention.
In this embodiment, as shown in
The package X also includes a detachable area X2, which is part of an outer peripheral shape of the package X, and is detachable from the package X. The detachable area X2 is composed of an area surrounded by a cutting structure X2a (specifically, perforation or half-cutting) that cuts the package X, specifically of an area surrounded by an edge of the package X and the cutting structure X2a. The detachable area X2 is formed to cover a hereinafter described connection part Z1 of the label Z in a state where the label Z is bonded to the package X. As shown in
The body X4 is molded by a sheet shaped member (a sheet of thermoplastic resin or the like, for example) to be recessed at one or more places. In this embodiment, the sheet shaped member is molded to be recessed at plural places to have plural housing parts X of recessed shape, and have plural discharge openings X6, through which the drugs Y are discharged from the housing parts X3. The body X4 includes fitting projections X7 that project toward the side opposite to the surface to which the label Z is bonded. Plural projections X7 are formed with a distance from an end portion of the body X4. In this embodiment, two fitting projections X7 are provided and these two fitting projections are located with the cutout part X8 therebetween.
The closing member X5 is configured to be layered on the sheet shaped body X to close the discharge openings X6 of the body X4. Specifically, the closing member X5 is composed of a sheet shaped material, and layered on or more specifically bonded to the body X4 to cover the discharging openings X6 of the body X4.
The closing member X5 is configured to be torn more easily than the body X4. Specifically, the closing member X5 is composed of a sheet material, such as aluminum foil, and is configured to be torn by pressing, together with the housing part X3, a drug Y housed in the housing part X3 from the outside of the housing part X3 toward the closing member X5, causing the drug to be pressed against the closing member X5 and hence the closing member X5 to be torn. Whereby, the drug Y can be taken out (discharged) from a torn area of the closing member X5.
In other words, the discharging areas X1 are formed by tearable areas of the closing member X5 in the package X. The package X having the above configuration is a so-called blister pack and is known as a package for packing drugs used in the medical field. It is to be noted that, however, the package may contain drugs used in different fields.
The label Z according to this embodiment has a sheet like shape, and can be bonded to a surface in which the discharging areas Xl of the package X are formed. Specifically, the label Z includes an adhesive layer (not shown) on one surface side thereof , and is configured to be bonded through its one surface side to the package X. The label Z is formed to have an outer peripheral shape having a size substantially equal to or slightly smaller than the outer peripheral shape of the package X. With this, the label Z is configured not to project from the package X in a state where the label is bonded to the package X. The label Z includes a connection part Z1 that is electrically connectable to the detecting device of the present invention. The label Z includes a body sheet Z2 formed into a sheet like shape, a tearing structure Z3 that tears the body sheet Z2 along with discharging of the drug Y from the housing part X3, and a conductive wire Z4 that is formed on at least one of the surfaces of the body sheet Z2 so as to be electrically connectable.
The body sheet Z2 includes an insulating layer composed of a sheet material having electrically insulating properties (specifically, an insulating sheet formed of synthetic resin, synthetic paper, paper or the like), and an adhesive layer formed on one surface of the sheet material. Any sheet material is usable for the body sheet Z2 as long as it has electric insulating properties through its entire portion, and may include an insulating layer composed of plural sheet materials (not shown) stacked together.
The tearing structure Z3 is formed along a certain area within the body sheet Z2, and specifically formed to surround a certain area. In this embodiment, when the label Z is bonded to the package X, the tearing structure Z3 is formed to continuously or intermittently surround an area overlapping each discharging area X1 of the package X. The tearing structure Z3 is formed to have an annular shape (an elliptical shape in this embodiment) to correspond to the outer peripheral shape of the discharging area X1. Whereby, an area surrounded by the tearing structure Z3 of the body sheet Z2 (tearing structure inner area) Z2a is formed to overlap (specifically cover) the discharging area X1.
The tearing structure Z3 is not necessarily limited to a certain structure, and is formed, for example, by partially reducing a thickness of the body sheet Z2. Specifically, the tearing structure Z3 is formed by forming a line-shaped reduced thickness part between an inner area surrounded by the tearing structure Z3 and an area outside the inner area. Whereby, the tearing structure Z3 is configured to be torn more easily than the area other than the tearing structure Z3.
The conductive wire Z4 is formed by stacking a material having electric conductivity (silver, aluminum or the like, for example) on one surface of the body sheet Z2. A method for forming the conductive wire Z4 is not necessarily limited to a certain method, and it is possible to employ, for example, a method, in which silver ink is printed or aluminum edge treatment is performed on one surface of the body sheet Z2. The conductive wire Z4 is formed to have respective end portions converging to an end portion of the body sheet Z2 to thereby constitute a conductive circuit. That is, the connection part Z1 of the label Z is formed at a position to which the end portions of the conductive wire Z4 converge.
The conductive wire Z4 is formed to cross the tearing structure Z3, and overlaps the discharging area X1 of the package X when the label Z is bonded to the package X. Whereby, as shown in
When the detecting device according to the present invention is attached to the conductive-wire mounted package XZ, the end portion of the package X is cut by way of the cutting structure X2a, and thereby the detachable area X2 is detached from the package X. Whereby, as shown in
As the detecting device attachable to the conductive-wire mounted package XZ having the above configuration, a detecting device 1 shown in
The holding part 2 includes a first portion 2a that has a shape (rectangular shape) with an elongated side in one direction to contact the conductive-wire mounted package XZ. The holding part 2 includes a second portion 2b that is formed between the first portion 2a and the coupling part 3 to be located between both ends in the longitudinal direction of the first portion 2a (specifically, at a substantially center portion). The holding part 2 further includes a positioning structure 2c that positions the conductive-wire mounted package XZ relative to the detecting device 1.
The holding part 2 is composed of the pair of holding pieces 2d and 2e that are configured to hold or sandwich the conductive-wire mounted package XZ therebetween. That is, the pair of holding pieces 2d and 2e each have a portion constituting the first portion 2a of the holding part 2, and a portion constituting a second portion 2b of the holding part 2. The pair of holding pieces 2d and 2e are arranged to overlap each other, and have end portions coupled with the coupling part 3. In this embodiment, the coupling part 3 has a hinge structure through which the end portions of the pair of holding pieces 2d and 2e are coupled together.
The first holding piece 2e is configured to have part not overlapping the second holding piece 2d. That is, the holding part 2 has a non-overlapping part 2f, through which the pair of holding pieces 2d and 2e do not overlap each other. The non-overlapping part 2f is formed in an end portion of the holding part 2 along the longitudinal direction of the holding part 2 (specifically, along the entire area in the longitudinal direction). The first holding piece 2e includes an abutting part 2g that abuts against the connection part Z1 of the label Z. The abutting part 2g is electrically connectable to the conductive wire Z4 constituting the connection part Z1. That is, the detecting device 1 is electrically connectable to the conductive wire Z4 at the abutting part 2g.
As shown in
The pair of holding pieces 2d and 2e are configured to hold or sandwich the conductive-wire mounted package XZ therebetween when in the closed state. Specifically, with the conductive-wire mounted package XZ held or sandwiched between the pair of holding pieces 2d and 2e, the conductive-wire mounted package XZ is urged toward the second holding piece 2d by the first holding piece 2e. Along with this, the conductive-wire mounted package XZ is urged toward the first holding piece 2e by the second holding piece 2d. Whereby, the conductive-wire mounted package XZ is held or sandwiched by the pair of holding pieces 2d and 2e. It is to be noted that the method for allowing the pair of holding pieces 2d and 2e to hold or sandwich the conductive-wire mounted package XZ therebetween is not necessarily limited to the above method, and it may be configured so that the conductive-wire mounted package XZ is held or sandwiched by the pair of holding pieces 2d and 2e through frictions between the end portions which together constitute a hinge structure of the pair of holding pieces 2d and 2e, or the conductive-wire mounted package XZ is held by way of action of a spring member provided in the hinge structure.
The holding part 2 is configured to form a space R between the pair of holding pieces 2d and 2e when the pair of holding pieces 2d and 2e are in the closed state. That is, the holding part 2 is configured to hold the conductive-wire mounted package XZ in the space R.
Returning to
The holding part 2 (specifically, at least one of the pair of holding pieces 2d and 2e) includes a detecting device that detects the current flowing state of the conductive wire Z4 of the label Z by being electrically connected to the conductive wire Z4. The detecting device may be a device that records a change in current flowing state of the conductive wire Z4, or transmits such a change to an outside equipment. Such a recording device or a transmission device may be provided in the holding part 2 separately from the detecting device. In this embodiment, the detecting device is provided in the abutting part 2g.
Next, the description is made for the method of using the detecting device 1 having the above configuration. As shown in
Then, as shown in
Then, with the detecting device 1 attached to the conductive-wire mounted package XZ, the drug Y is discharged from the housing part X3 of the package X. Along with discharging of the drug Y, the conductive wire Z4 is cut, which causes a change in current flowing state of the conductive wire Z4. Whereby, such a change is detected by the detecting device 1. In a case where the information such as date and time in which such a current flowing state change occurred (drug taking information) can be recorded by the detecting device 1, or can be transmitted to an outside equipment, whether the drug Y has been discharged or not from the package X (or whether the drug Y has been appropriately taken or not) can be checked by checking the drug taking information.
As described above, according to the detecting device of the present invention, it is possible to achieve ease of attachment to the conductive-wire mounted package provided with a conductive wire that allows for electric current to flow to the package with a drug housed therein, and ensured electric connection with the conductive wire.
That is, since the pair of holding pieces 2d and 2e are movable toward and away from each other, the distance between the pair of holding pieces 2d and 2e can be increased by moving the pair of holding pieces 2d and 2e away from each other. Whereby, the conductive-wire mounted package XZ can be easily placed between the pair of holding pieces 2d and 2e. Thus, the detecting device 1 can be easily attached to the conductive-wire mounted package XZ, or electrical connection between the conductive wire Z4 and the detecting device 1 can be easily achieved.
In addition, provision of the positioning structure 2c enables the conductive-wire mounted package XZ to be positioned or preferably fixed relative to the holding part 2 (specifically, the pair of holding pieces 2d and 2e). Therefore, the electrical connection between the conductive wire Z4 and the detecting device 1 can be ensured. Further, the conductive-wire mounted package XZ can be held in the holding part 2 or sandwiched between the pair of holding pieces 2d and 2e. Therefore, the attached state of the conductive-wire mounted package XZ to the detecting device 1 can be securely maintained.
The positioning recess 2h formed in the first holding piece 2e is brought into projection and recess fitting with the conductive-wire mounted package XZ (fitting projections X7) when the conductive-wire mounted package XZ is held in the detecting device 1. Therefore, the relative positioning between the detecting device 1 and the conductive-wire mounted package XZ can be securely determined (preferably fixed), so that the electrical connection between the conductive wire Z4 and the detecting device 1 can be more ensured.
Further, in a state before the detecting device 1 is attached to the conductive-wire mounted package XZ, the connection part Z1 of the label Z is covered by the detachable area X2 of the package. Therefore, it is possible to prevent dust or moisture from adhering to the connection part Z1, or the connection part Z1 from being broken. That is, the connection part Z1 can be protected by the detachable area X2. On the other hand, the connection part Z1 of the label Z is exposed to the outside through the cutout part X8 by detaching the detachable area X2 from the package X, that is, by forming the cutout part X8. Therefore, the electrical connection between the holding part 2 and the connection part Z1 can be easily achieved.
The detecting device of the present invention is not necessarily limited to the above embodiments, and may be subjected to various modifications within the gist of the present invention. Also, the configurations or methods of the above-described embodiments may be optionally employed and combined together (a configuration or method of one embodiment may be optionally combined with a configuration or method of another embodiment. Further, it is a matter of course that a configuration or method according to each of various modified examples mentioned below may be optionally selected, and employed in a configuration or method of the above-described embodiments.
For example, in the above-described embodiments, the pair of holding pieces 2d and 2e are coupled together by way of the hinge structure, and the conductive-wire mounted package XZ can be held or sandwiched by the pair of holding pieces 2d and 2e through friction of the hinge mechanism or the action of the spring member within the hinge mechanism. However, the present invention is not necessarily limited to this.
For example, a detecting device 10 shown in
The spring member 5 is located between the pair of gripping pieces 4a and 4b, and the pair of gripping pieces 4a and 4b are urged in a direction in which they are pivotally moved away from each other about the coupling part 3 by the action of the spring member 5. Therefore, the pair of holding pieces 2d and 2e are held in the opened state by applying a force to move the pair of gripping pieces 4a and 4b toward each other against the urging force of the spring member 5. Whereby, the conductive-wire mounted package XZ can be easily placed between the pair of holding pieces 2d and 2e. In other words, the conductive-wire mounted package XZ can be securely held or sandwiched by the pair of holding pieces 2d and 2e, since they are held in the closed state by the action of the spring member 5.
In the above embodiments, the positioning structure 2c is composed of the positioning recess 2h. However, the present invention is not necessarily limited to this. For example, as shown in
As described above, in the case where the detecting device includes the positioning projection 2i, as shown in
In the above embodiments, as the package X, a sheet-shaped member such as a blister pack is used. However, the present invention is not necessarily limited to this. For example, a box shaped member may be used as long as it can be held or sandwiched by the pair of holding pieces 2d and 2e.
In the above embodiments, the fitting projections X7, and the receiving recesses X9 are formed in the package X. However, the present invention is not necessarily limited to this. For example, these may be formed in the label Z. Specifically, as shown in
A detecting device 12, which is to be attached to the conductive-wire mounted package XZ including the label Z provided with the fitting projection Z5 and the package X bonded thereto, includes a positioning structure 2c (specifically, the positioning recess 2h) in the first holding piece 2e, as shown in
According to the above configuration, as shown in
As shown in
The above-described detecting device 12 is attached to the thus configured conductive-wire mounted package XZ. Then, as shown in
Alternatively, as shown in
A detecting device 13, which is to be attached to the conductive-wire mounted package XZ including the label Z provided with the receiving recesses Z6 and the package Z bonded thereto, preferably includes the positioning structure 2c (specifically, the positioning projection 2i), and the abutting part 2g that abuts against the connection part Z1 of the label Z (specifically, is electrically connected to) the connection part Z1 of the label Z in the first holding piece 2e, as shown in
According to the above configuration, as shown in
In the above embodiments, the holding part 2 has the non-overlapping part 2f formed therein. However, the present invention is not necessarily limited to this. For example, the non-overlapping part 2f may not be formed by providing the pair of holding pieces 2d and 2e with substantially the same shape.
In the above embodiments, the positioning structure 2c is provided in the first holding piece 2e. However, the present invention is not necessarily limited to this. For example, the positioning structure 2c may be provided in the second holding piece 2d.
In the above embodiments, the positioning structure 2c is composed of the positioning recess 2h or the positioning projection 2i. However, the present invention is not necessarily limited to this. For example, the positioning structure 2c may be composed of the positioning recess 2h and the positioning projection 2i.
In the above embodiments, the conductive-wire mounted package XZ is formed by bonding the label Z to the package X. However, the present invention is not necessarily limited to this. For example, the conductive-wire mounted package XZ may be formed by forming a conductive fire by printing on the closing member X5 of the package X.
In the above embodiments, the cutout part X8 is formed by detaching the detachable area X2 from the package X. However, the present invention is not necessarily limited to this. For example, as shown in
As shown in
According to the above configuration, the detecting-device connection parts Z4a are located at positions separating away from each other. Thus, it is possible to prevent occurrence of failure of the electrical connection between the detecting device of each of the above embodiments and the label Z. Specifically, the abutting part 2g of the detecting device of each of the above embodiments is provided with plural areas (not shown)(hereinafter referred also to abutting areas) that are provided at positions corresponding to the respective detecting-device connection parts Z4a to abut against (being electrically connected to) the respective detecting-device connection parts Z4a. Therefore, when the detecting-device connection parts Z4a are aligned in straight line along one direction and hence have narrow intervals between the adjacent detecting-device connection parts Z4a, even slight shifting of the positional relation between the label Z and the detecting device at the time of attaching the conductive-wire mounted package XZ to the detecting device may cause one abutting area to abut against the adjacent detecting-device connection parts Z4a and hence cause occurrence of fault of the electrical connection. However, with the detecting-device connection parts Z4a being not aligned in straight line (specifically, not overlapping each other on a straight line), the distance between the adjacent detecting-device connection parts Z4a is increased. Whereby, it is possible to prevent one abutting area from abutting against plural detecting-device connection parts Z4a, and hence prevent occurrence of failure of the electrical connection as described above.
