Description

  The present invention relates to an easy-to-use tablet dispenser from a PTP sheet.

  Tablets and capsules that are used on a daily basis during drug administration are often individually packaged and distributed one by one to prevent deterioration and breakage due to ultraviolet light and moisture absorption. At that time, a PTP sheet, that is, a package in which a tablet or capsule is placed in a hollow sheet made of hard plastic and covered with an aluminum film or the like is often used. Aluminum film and the like can be easily broken, and the tablet is taken out. Hereinafter, in the present specification, the term “tablet” includes a capsule, the hard plastic side of the PTP sheet is referred to as the front side, and the side covered with an aluminum film or the like is referred to as the back side.

Some people who are taking medication on a daily basis may not be able to successfully take out PTP-packed tablets due to physical conditions. Also, since the size of the tablets varies, some people can take out large ones but not small ones. Therefore, there is a need for a tool for easily taking out PTP-packed tablets.

Various tablet ejectors have been disclosed in which a PTP-packed tablet is placed on the upper surface of a box having a tablet-sized hole on the upper surface, and only the tablet is dropped into the box by pressing the tablet from above.
Specifically, an extruding bar provided on the tip of a plate with a spring (Patent Documents 1 and 8), a PTP sheet placed on a box and pressed with a finger (Patent Document 2), an extrusion for extruding a tablet When the stick pushes the tablet, the drum is rotated to shift the PTP sheet so that the tablets can be taken out one after another (Patent Document 3). Furthermore, there are three types of holes on the upper surface with different sizes, a groove through which the PTP sheet passes in parallel with the holes, and a push-out method with a finger (Patent Document 4), and a push-up lever in the box. There are also disclosed those which are pushed out (Patent Document 5), those which are provided with a handle on the box, and which take out the tablet by utilizing the principle of the lever (Patent Documents 6-8).

  In addition, there has also been disclosed a method in which a cylinder is cut obliquely and is set up with an inclined surface facing upward, and a PTP sheet is sandwiched between the extruded plate and the cylindrical oblique surface and pushed out by the extruded plate (Patent Document 9).

  The problem to be solved by the present invention is to provide a tablet take-out device that allows a physically handicapped person or an elderly person who is handicapped or insufficient in force to easily take out a tablet held on a PTP sheet.

  The tablet take-out device of the present invention includes an outer box having a partition wall having a through hole therein, a rotatable drum having a hemispherical projection, and a tablet held on a PTP sheet between the partition wall and the drum. A gap for insertion, and the drum is rotated to take out the tablet from the PTP sheet.

  It is preferable to use an outer box in the shape of a letter “e” of katakana when viewed from above. A partition wall having a through hole exists at the position of the vertical bar of the letter “e” of the outer box, and includes a rotatable drum having a protrusion on one side of the partition wall, and is held by a PTP sheet between the partition wall and the drum. Insert the prepared tablets.

If the gap between the drum and the partition wall is about the thickness of the PTP sheet, the PTP sheet holding the tablet can be easily inserted into the gap. At this time, it is necessary to hold the tablet at a position facing the center of the drum with the front side of the PTP sheet facing the drum, the back side facing the partition wall. When the PTP sheet holding the tablet is inserted and the drum is rotated, the protrusion of the drum eventually presses the front side of the PTP sheet. Then, the back side of the PTP sheet is broken, and the tablet rolls out to the other side of the partition wall through the through hole of the partition wall.
The protrusions on the drum are preferably hemispherical.

The PTP sheet can be cut in advance for each tablet, and one piece of the PTP sheet holding one tablet can be inserted into the gap.
In many cases, a PTP sheet usually holds ten tablets in two rows of five. Such a PTP sheet can be cut vertically and inserted while shifting a PTP sheet holding five tablets in a row, and the tablets can be taken out one after another.

By using the rotation of the drum, even a physically handicapped person or an elderly person who has insufficient power or can use only one hand can easily take out the tablet from the PTP sheet.

Examples of the present invention are shown below, but the present invention is not limited to the examples.

FIG. 1 shows a principle diagram of the tablet takeout device according to the present embodiment as viewed from above. The outer box 10 has a partition wall 11 in the center. The space on the left side of the partition is shown as 12, and the space on the right side is shown as 13. The right space 13 has a bottom. A through hole 14 is provided in the center of the partition wall 11. Considering taking out tablets of various sizes from various PTP sheets, the through-holes should be large. Further, it is preferable that the through hole 14 is inclined from the left to the right because the tablet is easy to roll out.
In addition, although each corner is a right angle in FIG. 1, it is preferable to manufacture so that it may become roundish.

FIG. 2 shows a plan view (upper) and a side view (lower) of the tablet take-out device of this example. A plastic drum 21 is attached to the space 12 on the left side of the tablet take-out device. A space 13 with a bottom on the right side is a place where the extracted tablets are held.
In FIG. 2, among the member numbers shown in FIG. 1, some of the member numbers are omitted for easy understanding of the drawing. In the partition wall, a holding table 15 for holding the PTP sheet and a spring 16 for supporting the holding table 15 are provided.

A plastic drum 21 is manufactured as shown in FIG. Although this drum is cylindrical, the central part is recessed, and a hemispherical projection 22 is provided in the recess. The height of the protrusion is about the outer periphery of the drum. This drum is rotatably held in the left space 12.
In order to facilitate the rotation of the drum 11, it is preferable to perform knurl processing on the portion 23 having a large diameter outside the drum. Furthermore, in the tablet take-out device of the embodiment, a notch (not shown) is provided in a part of the drum so that it can be easily turned with a finger.

The width of the gap 17 between the drum 21 and the partition wall 11 is set such that the PTP sheet can be slid in. Specifically, the thickness is made slightly larger than the thickness of the PTP sheet where no tablet is present. Since the thickness of the PTP sheet itself is slightly different for each PTP sheet, the width of the gap in this portion is suitably about 0.5 to 3 mm.

The operation of the tablet extractor is shown in FIG. A tablet 20 is an oval shape with a diagonal line in the figure. In this figure, the member numbers are shown in FIGS.
The tablet held by the PTP sheet is inserted into the gap 17 between the drum 21 and the partition wall 11 (FIG. 3A: plan view). The PTP sheet is held by the holding table 15. When the drum 21 is rotated, the drum protrusion 22 pushes the PTP sheet (FIG. 3 (b): side view), and the PTP sheet on the holding table also pushes the spring 16 and goes down. When the drum 11 is further rotated, the front side of the tablet portion of the PTP sheet is pushed, the thin surface on the back side of the PTP sheet is torn and the tablet 20 is taken out, and the taken out tablet passes through the through-hole 14 of the partition wall 11 to the right. Rolls down into the space 13 (FIG. 3 (c): side view). Here, FIG. 3 (c) shows an arrow and a tablet in two positions to show how the tablet rolls down.
When the tablet rolls down and then releases the drum, the PTP sheet is returned to the top by the force of the spring 16.

In order to hold the PTP sheet, it is necessary that the front side of the tablet is directed toward the protrusion of the drum and the thin part on the back side of the tablet is directed toward the hole of the partition wall.
When the PTP sheet holding the tablet 20 is sandwiched in the gap 17, the tablet is sandwiched so as to be held in the center. The portion where the width of the gap is narrowed (the outer peripheral portion 23 of the drum) is between the tablets, and the PTP sheet can be firmly held in the groove.
When a PTP sheet holding a tablet is sandwiched in this groove, it is held on a holding table. When the drum is rotated, the PTP sheet is lowered into the groove. As the tablet 20 descends, the tablet 20 is compressed by the hemispherical projection 22 of the drum, and eventually the tablet breaks through the back surface and is discharged from the through hole 14 of the partition wall 11 to the right space 13.

  The tablet take-out device of the present embodiment can also be used for wrapping a drug oblate. If a bag-type wafer is placed in the right space 13 at a position where the taken-out tablet rolls, an oblate-wrapped tablet can be obtained. Bag-type wafers are commercially available, but you can also make your own from a single flat wafer.

Those who take tablets may also take powder. At that time, if a bag-type wafer is placed in the right space 13 and the powdered medicine is put and sealed here, it becomes easy to put the powder into the wafer.
Even when taking both tablets and powders, a bag-type wafer is placed in the right space 13, the tablets are first taken out of the PTP sheet, and then powders are added to seal the wafers.

In the first and second embodiments, the number of protrusions of the drum is one, but a plurality of protrusions may be used. When it is desired to take out a plurality of tablets one after another, it is more convenient to have a plurality of protrusions.
The partition may be pluggable and replaceable. In this case, it is preferable to prepare ones having different hole sizes and to use ones having holes that just fit the tablets. When taking out tablets of different sizes, it is preferable to use a partition wall having holes of a size suitable for the tablets.
A method for holding the drum rotatably is a design matter, in which a shaft may be used.
