Description

The present invention relates to a chemical cassette for supporting a dispensing operation in a hospital pharmacy or the like, and more particularly to a chemical cassette that stores and arranges chemicals and discharges them in order from the end.
In addition, the medicines are applicable as long as the medicines and auxiliary medicines can be arranged and stored.

Chemical cassettes that are arranged to sequentially discharge by sequentially energizing and storing aligned chemicals toward the chemical discharge port, and chemicals that are sequentially stored and discharged on a gently sloping sliding surface Several types of cassettes have been developed and put into practical use (for example, see Patent Documents 1 to 5).
Specifically (for example, refer to Patent Document 1), in a chemical cassette that arranges and stores chemicals contained in a container that can rotate on its axis, such as an injection ampule, a movable lid having a cut-off portion into which the chemicals can be inserted. The top chemicals are discharged sequentially by rotating the shaft.

In addition, in a chemical cassette suitable for the sequential discharge of chemicals such as an infusion bottle (for example, see Patent Document 2), a discharge member that connects a flat plate portion and a curved plate portion has a flat plate portion that extends over the sliding surface. In the state where the rocking center is placed on the sliding surface, it is provided in the vicinity of the falling end of the sliding surface, and the chemicals are discharged one by one each time the rocking is performed.
Further (see, for example, Patent Document 3), the discharge mechanism is composed of a swash plate portion, a cam mechanism, and a link so that the drive source and the like are located below the sliding surface, and the follower is moved up and down alternately when the chemicals are discharged. There is a chemical cassette.

In addition, for example (see Patent Document 4), in order to stabilize the advancement of the aligned and stored chemicals, the discharge mechanism is composed of an attachment part, a roller array part, a stopper, and an elevating mechanism. There is a chemical cassette that is designed to raise the roller array to the top of the stop.
Also, for example (see Patent Document 5), the slide mechanism is configured with a plurality of followers linked so as to simplify the slide face forming member by allowing an increase in the slope of the slide face and to perform the discharge operation with simplicity and small size. There is also a chemical cassette in which the discharge mechanism is strengthened by alternately moving the follower up and down during the discharge of the chemical.

In such a conventional chemical cassette, the method of sequentially discharging the top chemical being inserted by rotating the movable lid about the axis has a simple discharging mechanism, but the chemical to be stored and discharged is a so-called round object such as an ampule. It was limited to. On the other hand, a swinging type or a vertically moving type discharging mechanism has been adopted for sequentially discharging chemicals that are difficult to roll, such as a box.
However, the swinging and up-and-down type discharging mechanisms have been sufficiently solved, such as the large number of parts, which makes it difficult to reduce costs, and the time and effort required to ensure smooth discharging operations. There are no complaints either.
Therefore, by further devising the discharge mechanism, it becomes a technical problem to realize a chemical cassette that can sequentially discharge chemicals that are difficult to roll, such as a box, by rotating the shaft of the discharge member.

  The chemical cassette of the present invention (Solution 1) was created in order to solve such a problem. The chemical cassette is aligned and stored in an aligned storage space that is inclined with the discharge side lowered. In the chemical cassette that sequentially discharges, the discharge mechanism disposed on the discharge side of the aligned storage space includes a horizontal support shaft that is orthogonal to the chemical alignment direction of the aligned storage space, and a short diameter portion. An eccentric member formed with a long diameter portion and supported by the support shaft so as to be axially rotatable, and intermittently pushes the long diameter portion from below the alignment storage space into the alignment storage space as the shaft rotates. Further, it is provided further on the discharge side than the eccentric member, and prevents the chemicals in the aligned storage space from passing over the eccentric member, but the chemicals pushed up by the long diameter portion of the eccentric member. Allow overcoming Characterized in that it comprises a output regulating member.

  Further, the chemical cassette of the present invention is (Solution means 2), the chemical cassette of the above-mentioned solution means 1, wherein the discharge restriction member or the upper end portion of the discharge restriction member is a rotatable roller. It is characterized by.

  In such a chemical cassette according to the present invention (Solution 1), in the standby state / non-discharge state where the discharge mechanism stops operating after the chemicals are discharged, the eccentric member has the short diameter portion. Because it is stationary with the long diameter part facing down, the top of the chemicals that have slid down the aligned storage space tries to pass over the eccentric member, but is blocked by the discharge restriction member. Stay there. When the eccentric member rotates at the time of discharging, the short diameter portion of the eccentric member goes down, and instead, the leading chemicals are pushed up by the long diameter portion of the eccentric member coming up.

As a result, the discharge restricting member is released and the leading chemicals pass over the eccentric member and the discharge restricting member and are discharged from the chemical cassette. In addition, at that time, when the front end part does not catch up with the long diameter part of the eccentric member, the next chemicals come into contact with the discharge restriction member and stop. Since the speed is reduced, the chemicals are discharged one by one regardless of whether the shaft rotation of the eccentric member is fast or slow.
Therefore, according to the present invention, it is possible to realize a chemical cassette that can sequentially discharge chemicals that are difficult to roll, such as a box, by rotating the shaft of the discharge member.

  Further, in the chemical cassette of the present invention (Solution means 2), when the chemical being discharged gets over the discharge regulating member, the roller rotates, so that Therefore, the chemicals can be discharged smoothly.

Example 1 of the present invention shows the structure of a chemical cassette, (a) is a perspective view of the chemical cassette in which chemicals are aligned and stored, (b) is a perspective view of only the chemical cassette, and (c) is discharged. The side view of the partial cross section which concerns on a mechanism and its peripheral part, (d) is a perspective view of an eccentric member. The discharge operation is shown in time series, and (a) to (c) are all side views of a partial cross section related to the discharge mechanism and its peripheral part. About Example 2 of this invention, the structure of a chemical | medical agent cassette is shown, and it is a perspective view of a baseplate front-end | tip part and an eccentric member.

About the chemical | medical agent cassette of such this invention, the specific form for implementing this is demonstrated by the following Examples 1-2.
The embodiment 1 shown in FIGS. 1 and 2 embodies all the above-described solving means 1 and 2 (claims 1 and 2 as originally filed), and the embodiment 2 shown in FIG. It is a modification.
In the illustration, for the sake of simplicity, fasteners such as bolts, coupling tools such as hinges, electric circuits such as motor drivers, electronic circuits such as controllers, etc. are omitted from the illustration. The illustrations focus on what is needed and what is relevant.

  About the Example 1 of the chemical | medical agent cassette of this invention, the specific structure is demonstrated with reference to drawing. 1A is a perspective view of a chemical cassette 10 in which the chemicals 8 are aligned and stored, FIG. 1B is a perspective view of only the chemical cassette 10, and FIG. 1C is a diagram relating to the discharge mechanism 20 and its peripheral portion. FIG. 5D is a perspective view of the eccentric member 22 of the discharge mechanism 20.

  The chemical cassette 10 includes a bottom plate 11 and left and right side plates 12 and 12 as members that define an alignment storage space for arranging and storing the chemicals 8 in a line. The bottom plate 11 is inclined and the upper surface is smooth and is a sliding surface for the chemicals 8, and the aligned storage space on the bottom plate 11 is inclined with the discharge side lowered. The side plate 12 is formed at an appropriate height so that the chemicals 8 do not get over even if the chemicals 8 swing left and right or slightly move up and down. The front plate 13 located at the forefront of the discharge direction is not essential, but is equipped with a discharge sensor 14 that detects the discharge of the chemicals 8, and the discharge side of the aligned storage space immediately behind the front plate 13 has a chemical on the discharge side. A discharge mechanism 20 for sequentially discharging the class 8 and an origin sensor 16 for determining the rotation reference position are arranged, and a motor 15 for rotating the discharge mechanism 20 is arranged behind the bottom plate 11 behind it. ing.

  The discharge mechanism 20 includes a support shaft 21 that is axially rotated by an appropriate transmission member such as the rotation drive motor 15 and a reduction gear, an eccentric member 22 that is supported by the support shaft 21 so as to be rotatable, and a front plate 13 A discharge restriction roller 23 (discharge restriction member) provided above is provided. The support shaft 21, the eccentric member 22, and the discharge restriction roller 23 both have a horizontal axial direction and extend to the left and right, and the chemical alignment direction of the aligned storage space is orthogonal to the axial direction. Both the support shaft 21 and the discharge regulating roller 23 are supported by the side plate 12 in the illustrated case, but may be supported by a member other than the side plate 12, such as a dedicated support column.

  The eccentric member 22 is illustrated as a rod-like member in which a hard cylindrical body is covered with a soft cylindrical body, but the cross-sectional shape perpendicular to the axial direction is the same everywhere in the axial direction, apart from a conductive portion such as a rotating pulley. In addition, in the cross section, the short diameter portion 22a and the long long diameter portion 22b having a short outer diameter viewed from the support shaft 21 at the rotation center are of different diameters. Further, the support shaft 21 is located where the height difference between the center position of the support shaft 21 and the line extending from the upper surface of the bottom plate 11 to the discharge side is larger than the diameter r of the short diameter portion 22a and smaller than the diameter R of the long diameter portion 22b. Since the eccentric member 22 rotates about the support shaft 21, the eccentric member 22 intermittently pushes the long diameter portion 22b from the bottom of the aligned storage space into the aligned storage space. ing.

  Since the discharge restriction roller 23 is provided above the front plate 13 and is located further on the discharge side than the eccentric member 22, the discharge restriction roller 23 interferes with the extension line to the discharge side of the bottom plate 11 or is positioned slightly above. If the chemicals 8 that have slid down the upper surface of the inclined bottom plate 11 do not interfere with the eccentric member 22, they are abutted. In addition, the discharge restriction roller 23 is held horizontally so that the shaft can freely rotate, and the height is suppressed to such an extent that it interferes with the lower part of the chemicals 8 but does not interfere with the upper part or the intermediate part. Therefore, the chemicals 8 in the aligned storage space are prevented from passing over the short diameter portion 22a of the eccentric member 22, but the chemicals 8 pushed up by the long diameter portion 22b of the eccentric member 22 are allowed to get over. It is a regulating member.

  About the chemical | medical agent cassette of this Example 1, the use aspect and operation | movement are demonstrated referring drawings. FIGS. 2A to 2C are side views of partial cross sections of the discharge mechanism 20 and its peripheral part, and show the operation of the discharge mechanism 20 for discharging the leading chemicals 8 in time series. ing.

  The chemical cassette 10 is used as a single unit, and the chemicals 8 are stored in a line in the aligned storage space that is surrounded by the bottom plate 11 and the side plate 12 from three sides and opened upward. Then, when the rotation drive motor 15 is actuated in response to an operation of an operation member (not shown) or a discharge command from the outside, and the support shaft 21 and the eccentric member 22 perform 360 ° shaft rotation, the discharge mechanism 20 leads the head. The chemicals 8 are discharged forward. The chemicals 8 may be rectangular such as a box or round such as a bottle. The discharge operation will be described below with reference to FIG. 2 by taking the square box-shaped chemicals 8 as an example.

  First (see FIG. 2 (a)), in the standby state / non-discharge state in which the discharge mechanism 20 stops operating after waiting for the discharge of the chemicals 8, the eccentric member 22 faces the short diameter portion 22a upward and the long diameter portion 22b. Since the entire eccentric member 22 is lower than the extension line of the bottom plate 11, the chemicals 8 stored in the aligned storage space slide down on the upper surface of the bottom plate 11 due to the inclination, of which the top Since the discharge side and front side portions of the chemicals 8 pass over the eccentric member 22 and come into contact with the discharge restriction roller 23, they cannot move to the discharge side any more and stop. The rear portion remains on the bottom plate 11 and remains above the eccentric member 22. The second and subsequent chemicals 8 are also stopped in order in the crushing state and remain on the bottom plate 11.

  And (see FIG. 2 (b)), the eccentric member 22 is axially rotated around the support shaft 21 at the time of discharging, and the direction of the rotation is a direction that contributes to discharging the leading chemicals 8 (clockwise in the figure). )It has become. Specifically, the long diameter portion 22b rises from the lower side toward the bottom plate 11 and close to the bottom plate 11, and then the long diameter portion 22b protrudes upward from the extension line of the bottom plate 11 and protrudes into the aligned storage space. Therefore, the discharge side / front side portions of the chemicals 8 are pushed up by the long diameter portion 22b. Further, the long diameter portion 22b rises while moving forward toward the discharge side, so that the leading end of the top chemicals 8 is pushed away from the discharge restriction roller 23 and becomes higher than that roller.

  Then (see FIG. 2 (c)), the eccentric member 22 continues to rotate, and the long diameter portion 22b advances to the discharge side. Therefore, the leading chemicals 8 also move forward a little, and the discharge side of the chemicals 8 The front part moves on the discharge regulation roller 23. Then, the long diameter portion 22 b starts to move downward and away from the leading chemicals 8, so that the discharge side / front side portions of the leading chemicals 8 ride on the discharge restriction roller 23. Even in this state, since the top chemicals 8 are inclined with the discharge side lowered, the top chemicals 8 slide on the bottom plate 11 and the discharge regulation roller 23 and are discharged from the chemical cassette 10. In addition, at this time, the forward movement of the long diameter portion 22b urges the leading chemicals 8 toward the discharge side, and the discharge regulating roller 23 is rotatable, so that the leading chemicals 8 are smoothly discharged.

After the discharge, the shaft rotates further and the eccentric member 22 rotates 360 ° in total, and the short diameter portion 22a goes up and the long diameter portion 22b goes down to return to the standby state / non-discharge state. And wait for the next chemical 8 to be discharged. In this state, the second and subsequent chemicals 8 slide down the upper surface of the bottom plate 11, and the second chemical 8 is stopped by the discharge restriction roller 23 so as to pass over the eccentric member 22, and discharged. It becomes the waiting top chemicals 8.
In this way, even with the chemical cassette 10 equipped with the simple discharge mechanism 20 with a small number of parts, the chemicals 8 are discharged forward one by one without causing inconvenient continuous discharge.

About the Example 2 of the chemical | medical agent cassette of this invention, the specific structure is demonstrated with reference to drawing. FIG. 3 is a perspective view of the tip of the bottom plate 11 and the entire eccentric member 22.
This chemicals cassette is different from that of Example 1 described above in that the end on the discharge side of the bottom plate 11 has a comb shape, and the long diameter portion 22b of the eccentric member 22 has a comb shape. The point and the comb-tooth-shaped part of both the members 11 and 22 are the points which are loosely fitting alternately.
In this case, the end on the discharge side of the bottom plate 11 is extended to the vicinity of the short diameter portion 22a of the eccentric member 22, and the gap between the bottom plate 11 and the discharge restricting roller 23 is narrowed. It will be discharged smoothly without coming into contact with 22a.

[Others]
In the above-described embodiment, the short diameter portion 22a and the long diameter portion 22b formed on the eccentric member 22 are one each, but a plurality of short diameter portions 22a and long diameter portions 22b are formed if they are alternately formed. In this case, the rotation amount of the eccentric member 22 in one discharging operation may be smaller than 360 °.
Further, in the above embodiment, the discharge restricting member is constituted by only the roller 23 supported so as to be axially rotatable by the both side plates 12. However, the discharge restricting member is constituted by a fixed member having a raised front plate 13, for example. Furthermore, you may comprise by the combination of such a fixing member and the roller 23 of the upper end part.
Further, the support shaft 21 is not limited to the one passing through the eccentric member 22 as described above, and may be divided at both ends of the eccentric member 22, and is formed integrally with the eccentric member 22. Also good.

The chemical cassette of the present invention can be used alone as described above, or may be incorporated in a medicine dispensing device. In typical built-in use, a large number of medicine dispenser shelves are arranged in a shelf, but in that case, if the bottom plate of the chemical cassette alone is not tilted in advance, the shelf plate should be tilted forward. The necessary inclination can be given to the aligned storage space.
In addition, the chemical cassette of the present invention is suitable for automatic discharge and automatic dispensing for drugs that are difficult to roll, such as boxed set drugs, but the chemicals in this specification are difficult to roll. It is not limited, it may be easy to roll, in addition to box-shaped drugs, injection drugs in containers such as ampoules, vials, contrast agents, etc., and pharmaceuticals such as tablets, powders, ointments, eye drops contained in bottles, etc. Other auxiliary chemicals are applicable if they can be stored in a line.
