Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tablet slicing device for pouring oral tablets for treating or preventing a disease into a receiver and dividing or crushing the tablets.

[0002]

BACKGROUND OF THE INVENTION Oral drugs for treating or preventing diseases include tablets, powders or granules, capsules or liquids. The liquid can be easily taken from infants to the elderly. The powder can be taken relatively easily by taking it with water or hot water. The capsules differ depending on the size, and it is difficult for infants and the elderly to take large capsules, but it is possible to take only the powder from the capsules as needed. Tablets also come in various sizes, but tablets with a particularly large outer diameter may cause a throat clogging for infants or the elderly, and caution should be exercised when taking them. In addition, although relatively small pet animals such as dogs and cats take tablets, they may be crushed into powder or granules in order to prevent the drug from being recognized. Furthermore, one tablet is divided into half tablets, etc. And then take it.

As described above, when orally administering a tablet having a relatively large outer diameter, in order to avoid the risk of clogging the throat, it is necessary to crush or crush the tablet into powder and then take the tablet. Yes, it becomes easier to drink. Figure 10
The method generally used for pulverizing or pulverizing into powder is generally shown. That is, the tablet 1 is placed on a table made of a hard material, and the hammer 100 is placed on the tablet 1 from above.
The tablet 1 is crushed or broken into small pieces by hitting. In addition, as another method, a tablet 1 is attached to pliers (not shown).
A method of sandwiching and crushing or breaking into small pieces by pressure is also adopted.

However, the hammer 10
In the method of crushing the tablet 1 by 0, a part of the tablet 1 is pulverized but the other part is turned into a large piece and scattered outward, resulting in significant variation in size. For this reason, the hammer 100 is again attached to the scattered large tablets.
The powder or particles were smashed by repeating the above process a plurality of times to obtain powder or particles having a substantially uniform size as a whole. In order to prevent such scattering, it is also practiced to wrap the tablet 1 in a paper or cloth and then crush it by giving a plurality of hits with a hammer 100. However, the impact of the hammer 100 may break the paper or cloth, and some of the tablets 1 may be scattered outward. Further, even in the method of crushing using pliers, the size of the particles of the tablet 1 becomes non-uniform and the particles scatter outward.

As described above, the method of crushing using the hammer 100 or the pliers has a problem that much time is required to make the size of the particles of the tablet 1 substantially uniform. Furthermore, some of the scattered tablets 1 are difficult to find because they have been shredded into small pieces, and if left unattended, a prescribed amount of the drug cannot be taken and prescribed treatment or prevention cannot be performed. A problem arises. Further, it is difficult to carry a hammer 100 or pliers for crushing tablets.

In view of the above problems, the present invention can easily make a tablet into small pieces without scattering, and

A knob 6 is fixed to the other end of 3. The knob portion 6 is fixed by being screwed into the other end of the screw portion 13. As the fixing means of the knob portion 6, any means can be adopted as in the embodiment described above. Further, it is optional to form the knob portion 6 into various shapes such as a shape of a popular character.

Next, a method of using the tablet slicing device having the above structure will be described, but it is basically the same as the above-described embodiment. That is, the receiver 10 and the lid 11 are relatively rotated to separate them from each other. Then, the disk-shaped tablet 1 is put into the recess 10 a of the receiver 10. At this time, the pressing portion 12 is retracted toward the lid 11. Then, the protrusion 11a of the lid 11 is screwed into the open end of the receiver 10 to be crowned. At this time, since the pressing portion 12 is retracted, the tablet 1 is not pressed. After that, the pressing portion 12 is advanced toward the tablet 1 by rotating the knob portion 6, and the tablet 1 is pressed by the tip of the pressing portion 4 to be broken from the center.

Further, the knob portion 6 is further rotated so that the screw hole 11c is formed.
The tablet 1 is crushed by the pressing part 12 when the pressing part 12 is gradually advanced with a strong force by the inclined surface of the screw of the screw part 13. As a result, the tablet 1 is

FIG. 4 shows a third embodiment of the tablet shredding device according to the present invention. In FIG. 4, the receiver 20 formed in a circular cup shape has a recess 20a into which the tablet 1 is put, and the receiver 1 shown in FIG.
The configuration is almost the same as 0. The inner diameter of the recess 20a is also set to, for example, about 12 mm. Further, a screw portion 20b having a predetermined length is formed on the inner peripheral surface of the open end of the receiver 20. The open end of the receiver 20 is capped by screwing a lid 21 into it.

In this third embodiment, the lid 21
A pressing portion 22 that fits into the recess 20a of the receiver 20 integrally with
Is formed in a protruding manner, and the screw portion 2 is provided on the lid 21 side of the pressing portion 22.
2a is formed. The pressing portion 22 has an outer diameter smaller than the inner diameter of the recess 2a of the receiver 2 and has a tip formed in a substantially conical shape. It is desirable that the angle of the tip should match the angle of the substantially mortar-shaped portion formed on the bottom surface of the recess 20a, as in the above-described embodiments.

Next, a method of using the tablet fragmentation device of the third embodiment described above will be described. First, the lid 21 is rotated and separated from the receiver 20, and then the receiver 20
The disk-shaped tablet 1 is put into the concave portion 20a of the. afterwards,
The pressing portion 12 integrally formed on the lid 21 so as to project from the opening end of the receiver 20 is fitted and crowned. Then, when the knob portion 6 is rotated, the pressing portion 12 comes into contact with the tablet 1 and
The tip of the pressing portion 4 presses the tablet 1 to break it from the center, and the inclined surface of the screw 20b and the screw portion 22a presses the tablet 1 with a strong force to crush the tablet 1. The tablet 1 crushed in this way is taken using the receiver 20 after the lid 21 is rotated in the reverse direction to separate from the receiver 20.

As described above, when the tablet 1 crushed using the receptor 20 is to be drunk, there is a risk that the receptor 20 is accidentally ingested because the diameter of the receptor 20 is as small as about 20 mm. . In order to prevent this, in the third embodiment shown in FIG. 4, the ends of the connecting band 23 are attached to the receiver 20 and the lid 21, respectively. As a means for attaching the connecting band 23, as shown in FIG.
The ends of the are fixed to the receiver 20 and the lid 21 by screws 24. In addition to this example, as a mounting means, through holes 25 are formed in the receiver 20 and the lid 21, respectively.

As a result, even if the receiver 20 and the lid 21 are separated, they are joined by the connecting band 23, so that even if the receiver 20 is accidentally swallowed, it is blocked by the connecting band 23 in the mouth and avoided in advance. can do. Further, the connecting band 23 also has a function of preventing loss of one of the receiver 20 and the lid 21 when they are separated. The connecting band 2 is provided between the receiver 20 and the lid 21.
Attaching 3 is also applicable to the first to third embodiments described above and the embodiments described later.

FIG. 5 is a modified example of the first embodiment shown in FIG. 1, in which the bottom surface of the recess 2a formed in the circular cup-shaped receiver 2 is formed into a flat surface and the recess 2 is formed.
The difference is that the tip end surface of the pressing portion 30 that fits into the inside of a to make the tablet 1 into small pieces is formed as a flat surface.

In such an apparatus, the method of crushing the tablet 1 into small pieces is substantially the same as the embodiment shown in FIG. That is, by rotating the knob portion 6 and advancing the pressing portion 30, the tablet 1 is gradually pressed by the screw hole 3d and the inclined surface of the screw of the screw portion 5 with a strong force to be pulverized into a substantially powdery state. According to the apparatus of the fourth embodiment, the bottom surface of the recess 2a of the receiver 2 and the tip end surface of the pressing portion 30 are formed flat, and therefore, the apparatus according to the above-described first to third embodiments is shown. Although the efficiency of fragmentation of the tablet 1 is slightly lower than that of the device, since the tablet 1 is pressed uniformly over the entire surface, the tablet 1 has a feature that it can be miniaturized into a uniform size.

FIG. 6 shows a further modification based on the modification of the first embodiment shown in FIG. 5, in which the bottom surface side of the recess 40a of the circular cup-shaped receiver 40 is substantially conical. On the other hand, the pressing portion 41 fitted in the concave portion 40a is formed to have a flat tip end surface. In this embodiment, on the bottom surface of the recess 40a of the receiver 40, as shown in FIG. 7, a columnar protruding piece 42 having a substantially conical tip and a flat other end is fixed by screws 44. is doing. Other configurations are similar to those of the embodiment shown in FIG. 5, and detailed description thereof will be omitted.

In this embodiment, after the tablet 1 is put into the recess 40a of the receiver 40, the above-mentioned knob portion 6 is inserted.
The tablet 1 is pressed between the protruding piece 42 and the pressing portion 41 to be made into small pieces by rotating the pressing portion 41 to advance the pressing portion 41, which is almost the same as the above-described embodiment. However, in this embodiment, the recess 40a of the receiver 40 is
Since the side projects and the pressing portion 41 side is flat, a space 43 is formed between the two, and the crushed tablet 1 retracts into this space 43, so that it is not made into a substantially powder form.
Therefore, it is suitable when the tablet 1 is divided into particles larger than powder. In this embodiment, the bottom surface of the recess 40a of the receiver 40 may be formed flat while the tip of the pressing portion 41 is formed in a substantially conical shape, which may be changed to the opposite relationship. Further, not limited to this embodiment, in each of the above-described embodiments, the bottom surface of the recess of the receiver is formed into a substantially conical shape by the protruding piece 42 and the like, while the tip of the pressing portion is formed into a substantially mortar shape. The tablet 1 may be pressed.

In each of the above embodiments, the tablet 1 is divided into small pieces and formed into powder or particles, but it may be necessary to divide the tablet 1 into two pieces in some cases. In this case, in the embodiment shown in FIG. 6, it is possible to use the protruding piece 45 shown in FIG. 8 instead of the protruding piece 42 fixed to the bottom surface of the recess 40a of the receiver 40 with the screw 44.

That is, the protruding piece 45 shown in FIG. 8 has an edge 45a having a ridge line at the tip thereof. Then, after the tablet 1 is put into the recess 40a of the receiver 40, the knob portion 6 is rotated to advance the pressing portion 41, so that the tablet 1 moves between the edge 45a of the protruding piece 45 and the pressing portion 41. Pressed between, the tablet 1 can be divided into two pieces by the edge 45a.

When it is desired to divide the tablet 1 into, for example, three or four parts, it can be realized by forming three or four edges having a ridgeline at the tip of the protruding piece 45 from the center. As a result, the tablet 1 placed in the recess 40a of the receiver 40 is divided into a plurality of pieces by the pressing portion 41 according to the number of edges. Even if the edge having such a ridge is formed at the tip of the pressing portion 41 and the bottom surface of the recess 40a of the receiver 40 is formed flat,
Similarly, it can be divided into a plurality of pieces.

FIG. 9 shows a modification of the means for connecting the receiver and the lid. That is, a rod-shaped pin 51 having a tip projecting into the recess 50a is fixed to the opening end side of the receptacle 50 formed in the shape of a circular cup by implantation. On the other hand, one end of the lid body 52, which is capped on one end of the receiver 50,
Small diameter portion 52a having an outer diameter dimension to be inserted into the recess 50a
Are formed. The pin 5 is attached to the small diameter portion 52a.
An L-shaped engaging groove 52b that engages with 1 is engraved.
The engagement groove 52b is formed in a shape that extends from one end of the lid 52 in the axial direction and is then bent in the circumferential direction.

To cap the receiver 50 with the cover 52, first, the pin 51 on the receiver 50 side and the engaging groove 52 on the cover 52 side.
After matching b, the receiver 50 and the lid body 52 are relatively pushed, and the pin 51 reaches the bending point of the engagement groove 52b. After that, the receiver 50 and the lid 52 are relatively rotated to engage the pin 51 with the circumferential portion of the engaging groove 52b, so that the two are capped irremovably in the axial direction. . As a result, when the tablet 1 is thereafter made into small pieces, even if the pressing portion is pressed against the tablet 1, the pin 51 and the engaging groove 5 are
Since the axial movement is blocked by the engagement with the circumferential portion of 2b, the lid 52 does not separate from the receiver 50.

The tablet fragmentation device described above is constructed in a small size, which is particularly suitable for carrying. Therefore, the receptor,
The lid, the pressing portion, and the like are preferably made of a material that is lightweight and has excellent workability. Examples of such materials include metals such as titanium and aluminum. Further, even if a synthetic resin having a strength necessary for making tablets into small pieces is formed by molding, the weight and safety can be improved. However, this tablet slicing device has an inner diameter of the recess of the receiver of 12 m.
Since it is formed in a small size of about m, another metal material may be used, and a stainless material is suitable as the material. Further, it is also possible to combine the materials such that only the part that comes into contact with the tablet is made of metal and the other part is made of synthetic resin. In addition, it is desirable to perform surface treatment such as electrolytic or electroless plating on the receiver, the lid, and the pressing portion which are made of a metal material or synthetic resin in order to improve appearance and prevent rust.

In each of the embodiments, the screw portion is integrally formed so as to project from one end of the pressing portion fitted into the recess of the receiver, but it is also possible to form these separately and then fix them integrally. At this time, the pressing part and the screw part may be configured to be rotatable, and the screw part may be rotated when pressing the tablet, but the pressing part may be stopped together with the tablet. Further, the inner diameter of the recess of the receiver described above is about 12 mm, but the invention is not limited to this inner diameter dimension.
If necessary, the size can be changed to several mm to several tens of mm. In addition to the above, it is needless to say that various modifications can be made without departing from the present invention.
