Further, as shown in FIG. 9A, the discharge section 36 is further provided with a sensor 46 and a stopper section 45 . Here, the sensor 46 senses the tablets 10b ejected from the ejection port 42 depending on how much the laser beam 50 emitted from the irradiation unit (not shown) is received. For example, when the tablet 10b passes through the ejection port 42 and the laser light 50 is blocked by the tablet 10b, it is sensed that the tablet 10b has been ejected. The stopper portion 45 opens and closes together with the door portion 40, and as shown in FIG. 9B, when the door portion 40 is closed, the stopper portion 45 is also closed. As a result, the tablet 10b does not pass through the discharge port 42, so that the sensor 46 does not detect the tablet 10b when the door portion 40 is closed.

A projection 38 to be inserted into the groove 32 of the storage section 16 is formed on one longitudinal side surface of the joint section 37 on the cassette section 4 side, as shown in FIG. In addition, a printed circuit board (not shown) connected to the sensor 46 and a communication unit (not shown) for transmitting information that the sensor 46 has detected a tablet to an external personal computer or the like are built in the joint portion 37.

In the present invention, the fixing portion 12 (supporting portion) and the pushing portion 14c (the shaft portion 14h, the arm 22a, the button 22b) constitute an pushing mechanism for pushing out the tablet, which is the object to be pushed, using the principle of leverage. ing. The object to be pushed is pushed out by the pushing part 14c. Such an extrusion mechanism itself can be used in addition to the medication management device 2 . In this case, the object to be extruded does not necessarily have to be a tablet, and it is not necessary to fix the PTP packaging sheet 10 to the fixing part 12 as described above. In this case, the holding sheet (corresponding to the PTP packaging sheet 10) holding the object to be extruded is supported by the supporting portion (corresponding to the fixed portion 12), and the arm is rotated with the shaft portion 14h as a fulcrum, and the button 22b is pressed. to extrude the object to be extruded.

Next, an assembly procedure and a usage method of the medication management device 2 according to the embodiment will be described with reference to the drawings. When assembling the medication management device 2, first, the button cover 14 and the storage section 16 shown in FIG. 2 are prepared. Then, the projecting portion 19 of the button cover 14 is fitted into the hole portion 21 of the storage portion 16, and the button cover 14 is attached to the storage portion 16 so as to be rotatable. Since there is elasticity between the holes 21 of the storage portion 16 , the button cover 14 can be easily assembled to the storage portion 16 . Moreover, the projecting portion 19 can be made difficult to come off from the hole portion 21 by forming the projecting portion 19 to have a thick tip.

Next, the fixed part 12 is prepared, and the PTP packaging sheet 10 is placed on the mounting part 12a of the fixed part 12 in the opened state, as shown in FIG. 3(b). In addition, the PTP packaging sheet 10 is placed on the placement portion 12a with the center folded in a mountain shape. Next, the fixing portion 12 is folded in a state where the position of the lid portion 12b is aligned with the position of the tablet pocket 10a of the PTP packaging sheet 10, and the claw portion 12f of the lid portion 12b is placed on the claw receiving portion 12e of the placing portion 12a. By engaging them, the PTP packaging sheet 10 is sandwiched between the mounting portion 12a and the lid portion 12b. As a result, the fixed part 12 is locked and the PTP packaging sheet 10 cannot be easily removed. In addition, since the PTP packaging sheet 10 is fixed while maintaining the folded state, it is possible to prevent the lid part 12b from floating when the PTP packaging sheet 10 originally in a flat plate shape tries to return to its original state. In addition, since the portion of the PTP packaging sheet 10 other than the tablet pocket 10a is covered with the fixed portion 12, it is possible to prevent the button 22b from being displaced when pushing out the tablet 10b.

Next, the projecting portion 12d of the fixing portion 12 holding the PTP packaging sheet 10 is aligned with the position of the notch 28, and the projecting portion 12d is inserted into the notch 28 to insert the fixing portion into the space 26 of the storage portion 16. Set 12. After the fixing portion 12 is set, the button cover 14 is rotated and closed, and the claw portions 15 of the button cover 14 are engaged with the claw portions 17 of the storage portion 16 . When the button cover 14 is put on the storage portion 16 , the projecting rib 13 formed on the fixing portion 12 is inserted into the hole portion 23 formed on the button cover 14 . As a result, the positional relationship between the button cover 14 and the fixing portion 12 is fixed, and the push-out portion 14c can be prevented from being displaced. As described above, the assembly of the cassette unit 4 is completed.

Next, the electrical component 6 is prepared, and the convex portion 38 of the electrical component 6 is inserted into the groove 32 of the storage portion 16 . Then, the cassette part 4 is slid to the discharge part 36 side, the electrical equipment part 6 is fixed to the cassette part 4, and the cover 8 is put thereon to complete the medicine administration device 2. - 特許庁By enabling the cassette part 4 to be attached to the electrical component part 6 in this way, it becomes possible to replace a plurality of cassette parts 4 . This makes it possible to accommodate PTP packaging sheets 10 of various sizes.

When using the medication management device 2, as shown in FIG. 10(a), the subject presses the pushing portion 14c corresponding to the position of the desired tablet. When the pushing portion 14c is pushed down, the arm 22a rotates around the shaft portion 14h, and the first rib 22c first contacts the tablet pocket 10a. Here, since the fixed portion 12 is formed to have a V-shaped cross section and corresponds to the turning angle of the extruded portion 14c, it is possible to secure a wide space for the arm 22a to turn. In addition, in the longitudinal direction of the button cover 14, only the central shaft portion 14b exists as a structure, and there is no structure such as a frame that blocks a finger pressing the push-out portion 14c. can do. In addition, the arm 22a is pivoted on the principle of leverage, and the outer side of the arm 22a is pushed down as a force point, so the tablet 10b can be pushed out with a small pushing force.

When the tablet 10b is pushed down by the first rib 22c, the tablet 10b breaks the aluminum sheet 10d covering the lower side of the tablet pocket 10a. When the arm 22a further rotates, the tablet 10b is pushed down after the second rib 22d abuts on the tablet pocket 10a, and the tablet 10b drops into the space 26 as shown in FIG. 10(b). In this way, by using the principle of leverage, the first rib 22c and the second rib 22d are brought into contact with the tablet pocket 10a with a time lag, and the tablet is pressed step by step, whereby the tablet 10b can be reliably pushed out. can. Therefore, it is possible to prevent a situation in which the tablet 10b is caught between the torn aluminum sheets 10d and cannot be completely pushed out from the tablet pocket 10a.

If the fixing portion 12 is formed to have a V-shaped cross section, as shown in FIG. becomes clear, the tablet 10b can be reliably pushed out when the push-out portion 14c is pressed. Further, since a space of a predetermined height can be secured between the storage portion 16 and the fixed portion 12, the extruded tablet 10b is securely stored in the storage portion 16 without being caught on the torn aluminum sheet 10d. be done.
After the tablet 10b is extruded, the height position of the extruded portion 14c is lowered, so that the subject can recognize at a glance which tablet 10b has been extruded.

Next, the subject tilts the medication management device 2 and takes out the tablet 10b stored in the space 26 of the storage section 16. FIG. FIG. 11 is a cross-sectional view of the medication management device 2 explaining how the tablet 10b is taken out. When the medication management device 2 is tilted so that the outlet 42 faces downward, and the door 40 is slid to open the outlet 42, the tablet 10b moves toward the outlet 42 as shown in FIG. Here, since the height of the discharge port 42 is regulated by the regulating portion 12p formed on the projecting portion 12d, the plurality of tablets 10b do not overlap and the orientation of the tablets 10b can also be regulated. Therefore, the sensor 46 disposed inside the joint 37 can accurately sense the number of tablets 10b to be taken one by one.

Furthermore, the tablet 10b passing through the discharge port 42 is guided to the slope portion 44. As shown in FIG. Since the slope surface 43 has a predetermined curvature, the tablet 10b moves along the slope surface 43 while changing the inclination according to the position of the slope portion 44. FIG. Therefore, there is a difference in moving speed between the tablet 10b in front of the discharge port 42 and the tablet 10b in the rear. Therefore, immediately after the front tablet 10b is taken out, the rear tablet 10b is not ejected immediately, so that each tablet passes through the sensor 46 and the passing tablets 10b are accurately counted.
The slope surface 43 does not have to be curved as long as a difference in movement speed can be generated between the tablet 10b in front of the discharge port 42 and the tablet 10b in the rear.

According to the extrusion mechanism of this embodiment, the first rib 22c and the second rib 22d are brought into contact with the tablet pocket 10a with a time lag using the principle of leverage, and the tablet 10b is pushed down step by step. The tablet 10b can be reliably pushed out. Further, according to the medication management device 2 of this embodiment, the number of tablets 10b to be taken can be accurately detected one by one, so medication administration can be performed with high accuracy. Further, by providing the sensor 46 at the discharge port 42, it is not necessary to provide the sensor 46 for each extruded portion 14c, so that a simple structure can be realized and the manufacturing cost can be suppressed.

In addition, in the above-described embodiment, the pushing portion 14c may include a plurality of buttons 22b. For example, as shown in FIG. 12(a), a first button 25a and a second button 25b may be provided. In this case, as shown in FIG. 12(b), it is preferable to design so that the positions of the first button 25a and the second button 25b from the shaft portion 14h are different. As a result, the first button 25a and the second button 25b come into contact with the tablet 10b through the tablet pocket 10a with a time lag when the push-out portion 14c is pressed. As a result, the tablet 10b that hits the tablet pocket 10a first breaks the aluminum sheet 10d, and the tablet 10b that is pushed out later can break the aluminum sheet 10d with a greater force.

If the first button 25a and the second button 25b are positioned at the same distance from the shaft portion 14h, the force will be distributed to the two tablets 10b, so the force of two tablets will be required. By arranging the second button 25b at different distances from the shaft portion 14h and setting a time lag, it is possible to push out the tablet 10b with less than twice the force. It is more effective if the heights of the first button 25a and the second button 25b are different. In particular, it is effective when combining and extruding a plurality of tablets 10b.
In the above-described embodiment, the medication management device 2 does not necessarily have to be used for clinical trials in the process of developing new drugs.

Here, the wall portion 12x is formed so as to surround the lower portion of the mounting portion 12a. The wall portion 12x is formed with a guiding portion 12z that is inclined toward the projecting portion 12d (the side of the discharge port 42) while narrowing the width X of the wall portion 12x on both sides in the width direction of the mounting portion 12a. there is By forming the guide portion 12z in this way, when the medication management device 2 is tilted, the tablet stored in the space 26 of the storage portion 16 is guided to the ejection port 42 by the guide portion 12z, and the tablet can be accurately ejected. can be guided to the discharge port 42 immediately.

Further, the supporting portion 12y has a columnar shape, and a plurality of supporting portions 12y are formed at predetermined intervals in the longitudinal direction at the center of the lower surface of the mounting portion 12a in the lateral direction. The upper end of the support portion 12y is fixed to the lower surface of the mounting portion 12a, and the lower end abuts on the bottom surface of the storage portion 16 when the fixing portion 12 is fixed to the storage portion 16. As shown in FIG. By providing the support portion 12y in this manner, it is possible to prevent the fixing portion 12 from being distorted when pushing down the pushing portion 14c to push out the tablet from the tablet pocket 10a.
