Description

  The present invention relates to a medicine container for containing a tablet and taking out the tablet according to a prescription.

  Conventionally, in hospitals, pharmacies, and the like, drug storage containers that store tablets and take them out according to prescriptions are used (see, for example, Patent Document 1). This medicine container is provided with a distribution rotor for discharging a predetermined number of tablets while rotating around the vertical axis in a medicine container which is an internal region of the container body (cassette body). On the outer peripheral portion of the distribution rotor, concave drug storage passages in which the tablets can be individually arranged are formed at predetermined intervals.

  The upper surface of the wall portion between the medicine storage paths is a guide surface having an arc shape in plan view for guiding the tablet. Then, on the rear side of the peripheral surface of the container main body, a predetermined amount of tablets arranged in the medicine storage path are provided in the discharge holes arranged in the lower part of the container main body (there may be one or a plurality of determined numbers). A partition plate is provided for discharging each one.

  In the medicine container 1 shown in FIG. 14, the guide surface 2 is formed with a flat surface portion 3 and a drop surface 5 that is coupled to the flat surface portion 3 so as to curve the adjacent wall portion 4 side. . The partition plate 6 is arranged such that a tip 7 thereof is positioned on the guide surface 2.

  In such a medicine container 1, when the distribution rotor 8 rotates, the tablets 10 stored in the medicine storage portion 9 are aligned with the medicine storage path 11, and when the medicine storage path 11 is positioned above the discharge hole, a partition is formed. The tablet 10 below the position defined by the plate 6 is discharged.

JP 10-314277 A

  In the conventional medicine container 1, the partition plate 6 is arranged such that the tip 7 is positioned on the guide surface 2. Therefore, it is at the same height as the starting height of the drop surface 5. For this reason, for example, when the tablet 10 to be handled is a half tablet (semi-circular), the edge portion 10 a of the tablet 10 is easily bitten between the partition plate 6 and the dropping surface 5.

  Then, this invention makes it a subject to provide the chemical | medical agent storage container which can store a tablet reliably in a chemical | medical agent storage path in view of the said subject.

  The drug storage container of the present invention is provided with a rotatable distribution rotor around the vertical axis in the internal storage part, which is an internal region of the storage container body, and is rotatable around the vertical axis on the lower outer periphery of the distribution rotor. A wall portion is provided in the wall portion, and a plurality of vertical drug storage paths are formed in the circumferential direction in which the tablet can be stored in the wall portion, and the upper surface of the wall portion is stirred while the tablet is stirred by relative rotation between the distribution rotor and the wall portion. A guide surface that guides the tablets toward the medicine storage path, a partition body that partitions the tablets stored in the medicine storage path is fixed to the container body, and a tablet below the partition body is provided below the partition body A medicine container that is allowed to drop into the discharge hole, wherein at least an upstream end portion of the partition from which the tablet moves is disposed below the guide surface.

  In the medicine container having the above structure, when the distribution rotor and the wall portion are rotated, a predetermined number of tablets are stored in the medicine storage path while being agitated, and another tablet is agitated on the guide surface. Since the partitioning body operates to move with the rotation of the distribution rotor and the wall while being placed, and at least its end is below the guide surface, another tablet placed and guided on the guide surface is When the medicine storage path storing the tablets is positioned below the partition body without being bitten between the partition body and the medicine storage path, the inside of the medicine storage path In this case, only the tablet below the partition body falls into the discharge hole.

  The medicine container of the present invention is characterized in that at least an upstream end of the partition body from which the tablet moves is dropped between the outer peripheral side of the guide surface and the container body.

  In the above configuration, another tablet that has been placed and guided on the guide surface by dropping at least the end of the partition body between the outer peripheral side of the guide surface and the container main body is separated by the partition body below it. It will be in a state to be.

  The drug container of the present invention is formed on the outer peripheral portion side of the guide surface with a concave stepped portion that is recessed downward over the entire circumferential direction of the wall portion. It is characterized in that an upstream end where the tablet moves is arranged.

  In the above configuration, since at least the upstream end of the partition where the tablet moves is arranged in the concave stepped portion, and this is positioned below the guide surface, it is placed on the guide surface. Another tablet that has been placed and guided is in a state of being squeezed by the partition below it.

  In the medicine container of the present invention, the distribution rotor is formed in a conical shape having a convex shape on the upper side, and the inclined surface for moving the tablet upward is directed toward the downstream side from the upstream end of the partitioning body. It is characterized by being formed.

  According to the above configuration, the tablet is lifted upward by the inclined surface of the partition, and when the tablet is moved (dropped) again when the partition is exceeded, the cone shape of the distribution rotor (conical surface) and the partition Combined with the body, particularly its inclined surface, it excels in tablet stirring function.

  According to the medicine container of the present invention, since at least the upstream end of the partition body is below the guide surface, another tablet placed and guided on the guide surface is separated by the partition body below the guide surface. It is possible to avoid a state in which the tablet bites between the partition and the medicine storage path.

  Hereinafter, a medicine container according to an embodiment of the present invention will be described with reference to the drawings. 1 is an overall schematic perspective view of a medicine container showing an embodiment of the present invention, FIG. 2 is a perspective view from above in a state in which a distribution rotor and a wall portion are incorporated in a holding frame, and FIG. 3 is a perspective view from below. 4 is a plan view with the holding frame omitted, FIG. 5 is a front view with the holding frame omitted, FIG. 6 is a longitudinal sectional view in the direction perpendicular to FIG. 5, and FIG. It is a perspective view which shows the movement of the tablet of a state.

  The medicine container 20 (cassetter) in this embodiment is used in combination with another medicine container 20 so as to form a ring shape in plan view. As shown in FIG. 1 to FIG. 4, the medicine container 20 (cassetter) includes a main body 21 that contains medicines, in particular tablets 22, and a case 23 having a hollow fan shape in plan view and a lower part of the case 23. A cylindrical holding frame 39 having an open upper side and a base 24 are formed. The main body 21 is connected to a front frame portion 25A having a semi-cylindrical portion 25 having a release portion 29 by opening the rear so as to be integrated from the rear. The distribution rotor 26, the wall portion 27 formed in an annular shape, and the holding frame 39 are mounted so as to be relatively rotatable, that is, rotatable in the same direction at different speeds.

  The distribution rotor 26 is formed in a conical shape having a convex shape on the upper side, and a plurality of plane portions 30 cut in the circumferential direction are formed on the outer circumferential conical surface 28 at predetermined intervals. That is, the conical surface 28 is formed by a composite surface of a curved surface and a flat surface. The maximum diameter of the outer peripheral side edge 26a of the lower surface of the distribution rotor 26 is set to be smaller than the inner diameter of the holding frame 39 by a thickness t1 of a medicine guide portion 38 (described later) of the wall portion 27. The distribution rotor 26 has a vertical support shaft 35 formed at the center thereof, and is configured to be rotatable in one direction around the support shaft 35 (axial center).

  The apex portion 31 of the distribution rotor 26 is located at a position lower than the upper edge 23a of the case 23. The case 23 is covered with a lid (not shown) after the tablet 22 is put into the case 23. The side wall of the case 23 is inclined toward the semi-cylindrical portion 25.

  The wall portion 27 is disposed on the lower outer peripheral portion of the distribution rotor 26, and the wall portion 27 is rotatable around a vertical support shaft 36 (axial center) in a state of being substantially in sliding contact with the lower surface 26 b of the distribution rotor 26. Is provided. The support shafts 35 and 36 are concentric and are configured to rotate in the same direction at different speeds, that is, relative speeds.

  The wall portion 27 has a medicine guide portion 38 that protrudes radially outward from the outer peripheral side edge 26 a of the lower surface of the distribution rotor 26. A plurality of drug storage paths 40 in the vertical direction capable of storing one tablet 22 are formed in the drug guide portion 38 at predetermined intervals in the circumferential direction. In the case of this embodiment, the height of the medicine storage path 40 is set to be equal to the height of the wall portion 27, and the circumferential width b1 thereof is a width in which only one half tablet 22 is stored. Is set. Between the outer peripheral surface 27a of the wall portion 27 and the inner peripheral surface 39a of the holding frame 39, a slight annular gap through which the tablet 22 cannot enter is formed.

  In the wall portion 27, the upper surface of the medicine guide portion 38 is a horizontal plane, and this horizontal plane is downstream from the upstream side A of the medicine storage path 40 while stirring the half-tablet tablet 22 by the relative rotation of the distribution rotor 26 and the wall portion 27. A guide surface 41 having an arc shape in a plan view that guides toward the side B is provided. The guide surface 41 is formed with a flat surface portion 41a and a drop surface 43 that is coupled to the flat surface portion 41a so as to curve the adjacent wall portion 27 side, that is, the upstream side.

  By the way, a stepped recess 45 (corresponding to a concave step) that is recessed downward is provided on the outer peripheral side of the guide surface 41 over the entire circumferential direction of the wall 27 (not in the medicine storage path 40). Formed. That is, this stepped recess 45 is also arc-shaped in plan view, and the vertical drop amount δ, that is, the vertical height from the guide surface 41 to the bottom surface 45a of the stepped recess 45, is described later. The amount is set such that the upstream end 46a can enter. The radial width b <b> 2 of the stepped recess 45 is smaller than the thickness of the tablet 22. The circumferential width b3 of the stepped recess 45 is set to be larger than the circumferential width b1 of the medicine storage path 40.

  Here, the configuration of the partition 46 will be described in detail with reference to FIGS. 8 is a perspective view from above showing the overall structure of the partition body 46, FIG. 9 is a perspective view from below, FIG. 10 is a horizontal sectional view at the boundary between the upper body portion and the lower body portion, and FIG. FIG. 8 is a longitudinal sectional view at the center in the length direction in FIG.

  As shown in these drawings, the partition body 46 is provided with a flat plate-like fixing portion 47 fixed to the rear portion of the holding frame 39 and the fixing portion 47 so as to be integrated with the fixing portion 47 so that the tablet 22 can be received from the upstream side to the downstream side. A main body 50 having an inclined surface 48 inclined upward toward the side. The fixing portion 47 is formed of metal (for example, stainless steel is used) or a synthetic resin (for example, ABS resin is used), and the main body portion 50 is an example of a silicon resin (a material rich in elasticity). Rubber may be used). The main body 50 is disposed near the lower part of the front surface 47 a (half-cylindrical portion 25 side) of the fixed portion 47.

  A pair of left and right elongate holes 51 and 52 are formed on one end side (upstream side in this case) of the fixing portion 47, and the fixing portion 47 inserts screws 53 and 54 into the elongate holes 51 and 52. The container body 21 is fixed through screw holes 56 and 57 formed in the support piece 55 protruding rearward from the holding frame 39. A plurality of screw holes 56 and 57 are formed in the vertical direction.

  The main body 50 is integrated with a base 60 fixed to the front surface 47 a of the fixing portion 47, a scooping portion 61 integrally formed so as to protrude further forward from the base 60, and a downstream side B of the scooping portion 61. The stirring assisting part 62 is formed. The bottom face 63 of the main body part 50 (the scooping part 61 and the stirring auxiliary part 62) is formed in a horizontal plane. The front surface 50 a of the main body 50 is curved so as to follow the curvature of the distribution rotor 26. In addition, a tapered surface 64 that is inclined forward is formed at an upper corner portion where the upper surface and the front surface of the main body 50 are continuous.

  Further, the main body portion 50 is configured such that an upper main body portion 66 and a lower main body portion 67 are coupled via a stepped surface 65 that is recessed backward in the vertical direction. It becomes a surface which opposes the circular arc surface 68 of the stepped recess 45 of the portion 27 with a slight gap in the front and rear. The lower surface 66a of the upper main body portion 66 is a surface that faces the guide surface 41 of the wall portion 27 in the vertical direction with a slight gap.

  That is, by fixing the fixing portion 47 to the support piece 55, the main body portion 50, that is, the scooping portion 61, forward from the slit 70 (which may be one or plural) formed in the rear portion of the holding frame 39. With the agitation assisting portion 62 inserted, the stepped surface 65 faces the arc surface 68 of the stepped recess 45 in the front-rear direction, and the lower surface 66a of the upper body portion 66 faces the guide surface 41 of the wall 27. .

  The inclined surface 48 is the upper surface of the scooping portion 61, the upstream side A end 61 a of the scooping portion 61 is formed thin, the tip is formed in a small arc shape, and the inclined surface 48 is the thickness of the base 60. The inclined surface 48 is formed in a plane inclined upward toward the downstream side B at a position protruding forward from the fixed portion. That is, the scooping portion 61 is formed so as to gradually become thicker from the downstream side A toward the upstream side B. The highest portion position 61 b on the downstream side B of the scooping portion 61 is located above the maximum diameter portion outer peripheral edge 26 a of the distribution rotor 26. The upper surface of the stirring assisting part 62 is a horizontal stirring assisting surface 71. A discharge hole 80 through which the tablet 22 in the medicine storage path 40 falls is formed at a position corresponding to the other side of the main body 50.

  In the medicine container 1 having the above-described configuration, the tablet 22 (half-tablet shape) is put into the case 23, and the distribution rotor 26 and the wall 27 are driven to rotate. Then, the tablet 22 slides down on the surface by the conical surface 28, and is placed on the guide surface 41 of the wall portion 27 in the vicinity of the lower peripheral edge 26 a of the distribution rotor 26, and the relative speed between the distribution rotor 26 and the wall portion 27. The tablet 22 in the case 23 is stirred while the tablet 22 placed on the guide surface 41 is guided to the downstream side B, guided to the dropping surface 43, and blocked by the bottom wall 39A of the main body 21. Thus, only one tablet is dropped and held in the medicine storage path 40. This is the same for each medicine storage path 40.

  As the wall portion 27 continues to rotate, the medicine storage path 40 storing the tablets 22 approaches the partition body 46 from the upstream side A. On the other hand, there are many tablets 22 placed on the guide surface 41, and there are tablets 22 stored in the medicine storage path 40. Here, the movement when a certain medicine storage path 40 storing the tablet 22 moves downward of the partition body 46 will be described. On the outer peripheral side of the guide surface 41, a stepped recess 45 that is recessed downward is formed. The upstream end 46 a of the partition 46 is in the stepped recess 45.

  Here, since the width b <b> 2 of the stepped recess 45 is smaller than the thickness of the tablet 22, the tablet 22 placed on the guide surface 41 does not enter the stepped recess 45. The upstream end 46 a of the partition 46 is in the stepped recess 45, that is, located below the guide surface 41, so that a certain medicine storage path 40 storing the tablet 22 is below the partition 46. The tablet 22 placed on the guide surface 41 is squeezed by the upstream end 46a of the partition 46 until it moves to. Only one tablet 22 stored in the medicine storage path 40 falls further downward from the discharge hole 80.

  On the other hand, as the wall 27 further rotates, the squeezed tablet 22 is guided upward by the inclined surface 48. As the wall portion 27 rotates, the squeezed tablet 22 sequentially moves to the downstream side B, so that the tablet 22 reaches the stirring assist surface 71 and further moves to the downstream side B to move to the downstream side B of the stirring assisting portion 62. The tablet 22 is stored in the medicine storage path 40 that has already been emptied by dropping from the discharge hole 80. The medicine container 1 in the embodiment of the present invention sequentially repeats the above operations.

  In addition, since the partition body 46 is entirely formed of a silicon resin rich in elasticity, it is possible to avoid a state in which the tablet 22 is bitten by itself, and to smoothly squeeze the tablet 22. Even if the tablet 22 is caught between the main body portion 50 and the guide surface 41, the bottom surface 63 of the main body portion 50 (the scooping portion 61 and the stirring auxiliary portion 62) is formed in a simple horizontal plane. The tablets 22 that have been bitten are easily maintained in the bitten state, and therefore have the function of not dropping unnecessary tablets 22 into the medicine storage path 40.

  The distribution rotor 26 has a conical shape, has no vertical portion, and has a horizontal guide surface 41 immediately below the lower peripheral edge 26a of the distribution rotor 26. Further, the conical surface 28 has a flat portion 30. Since it is formed in plural, the movement of the tablet 22 is sufficiently changed, so that the drug container 1 is excellent in stirring performance, and the tablet 22 can be securely stored in the drug storage path 40. It becomes. Further, a tapered surface 64 inclined downward to the front is formed in an upper corner portion where the upper surface and the front surface of the main body 50 of the partition 46 are continuous, and this guides the tablet 22 inward in the radial direction. Since it has a function of dropping as described above, it is particularly useful when the number of tablets 22 inside the container is reduced, and a reduction in stirring performance can be suppressed.

  By the way, if the tablet 22 is temporarily bitten between the partition 46 (the scooping portion 61) and the distribution rotor 26, a load is applied to the rotation of the distribution rotor 26. If it falls into the medicine storage path 40, the load is released, and at that time, the rotation of the distribution rotor 26 is instantaneously accelerated. However, in the embodiment of the present invention, even when the rotation of the distribution rotor 26 is instantaneously accelerated, the stepped recess 45 of the stepped recess 45 is prevented from dropping more than necessary tablets 22 into the medicine storage path 40. The circumferential width b <b> 3 is set larger than the circumferential width b <b> 1 of the medicine storage path 40.

  In addition, the shape of the partition body 46 is not limited to the said embodiment. For example, as shown in the rear view of the partition 46 in FIG. 12 and the bottom view in FIG. 13, the lower main body portion 67 is curved via a stepped surface 85 so as to be recessed backward from the rear surface 61 c of the scooping portion 61. 86 may be formed to form the groove 87. With this configuration, if the tablet 22 is caught between the rear surface 61c of the scooping portion 61 and the distribution rotor 26, the tablet 22 bitten into the concave groove portion 87 of the lower main body portion 67 moves, The tablet 22 is likely to fall into the medicine storage path 40, and if the medicine 22 is not stored in the medicine storage path 40, the tablet 22 can be dropped into the medicine storage path 40. Furthermore, since the rigidity of the lower main body portion 67 is lowered by forming the concave groove portion 87, the scooping portion 61 is easily deformed when the tablet 22 is bitten as described above. The tablet 33 can be prevented from cracking or chipping.

  In the above embodiment, the medicine storage path 40 is set to a height for storing only one tablet 22 and only one tablet 22 is dispensed. However, the present invention is not limited to this. As the medicine storage path 40 having a height that can accommodate a plurality of tablets 22, the partition body 46 is installed at a height corresponding to the case, so that the tablets 22 are dispensed according to the size. It is also possible to do. Also in this case, it is possible to prevent biting of the tablet 22 as in the above embodiment.

  In the above embodiment, in order to arrange the upstream end 46a of the partition 46 at a lower position with respect to the guide surface 41, a stepped recess having a drop amount δ that is recessed downward on the outer peripheral side of the guide surface 41. 45 was formed. However, the present invention is not limited to the above embodiment, and as shown by the phantom line d in FIGS. 5 to 7, the thickness t <b> 1 of the medicine guide portion 38 is reduced and the stepped recess 45 is not formed. In this way, it is also possible to arrange the upstream end 46 a of the partition body 46 at a position lower than the guide surface 41. Also in this case, the tablet 22 placed on the guide surface 41 is on the upstream side of the partition body 46 until a certain medicine storage path 40 storing the tablet 22 moves below the partition body 46 as in the above embodiment. It will be scooped by the end 46a.
