Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a crusher for crushing syringes, injection needles, drip needles, etc.

[Prior art and its issues]

In the past, syringes were mainly made of glass, but recently disposable syringes made of plastic are increasingly being used. This syringe has the advantage that it does not need to be sterilized each time, and there is no risk of bacterial infection due to repeated use. However, on the other hand, it has become necessary to promptly dispose of used syringes and the like to render them unusable. That is,
Ambiguous disposal methods run the risk of developing social problems, such as promoting the spread of stimulants, so careful disposal of used syringes and the like, which are generated in large quantities at hospitals, has been desired. The same is true when discarding a needle used for a glass syringe or a needle used for an intravenous drip, but no one with sufficient functionality has been proposed yet. Incidentally, Japanese Utility Model Application Publication No. 49-101565 discloses an apparatus for cutting empty cans and the like. In this device, the distance between the pair of pressure rollers installed on the upper stage is constant, so if you adjust the spacing to suit the pressure of empty cans with a small diameter or a syringe, you can use the pressure rollers to The crusher cannot penetrate into the body and simply moves on the pressure roller, making it practically unusable as a crusher that needs to process syringes of multiple sizes.

[Purpose of the invention] The purpose of the invention is to provide a syringe crusher that can promptly dispose of used syringes, Ringer's solution containers, etc. of different sizes to render them unusable. .

[Configuration of the present invention]

The structure of the present invention taken to achieve the above object is as follows. That is, the present invention includes a feeding chute, a feeding roller arranged below the feeding chute and arranged in parallel with a required interval, and a feeding roller arranged in parallel with a required spacing below the feeding roller, and a syringe, etc. a compression roller that compresses the material to make it easier to cut; an upper cutting roller that is placed below the compression roller and cuts the syringe, etc.;
and a lower cutting roller disposed below the upper cutting roller, the cutting direction of the syringe or the like intersecting the cutting direction of the upper cutting roller, and the feed roller changes the distance between the two rollers by rotating. One or both of the rollers are eccentrically provided so that the upper cutting roller and the lower cutting roller each include a smooth roller having a smooth circumferential surface and a cutting blade having a cutting blade formed on the circumferential surface. The smooth roller and the cutting blade roller are arranged so that the smooth surface and the cutting blade are in contact with each other or have a slight gap therebetween, and the cutting direction of the upper cutting roller and the lower cutting roller is is a crusher of crossed syringes, etc. The syringes, injection needles, drip needles, drip containers, etc. placed in the hopper are then sent from the feed roller to the compression roller, where they are compressed as they pass through the compression roller and sent to the next upper cutting roller. severed,
It is sent to the lower cutting roller. Since the lower cutting roller cuts in a direction that intersects the cutting direction of the upper cutting roller, even large pieces can be cut into smaller pieces using the upper cutting roller alone.

【Example】

The present invention will be explained in more detail based on embodiments shown in the drawings. Fig. 1 is a front view of an embodiment of the present invention, Fig. 2 is a cross-sectional view taken from Fig. 1, Fig. 3 is a diagram showing the arrangement of the feed rollers, and Fig. 4 is an upper cutting roller and a lower cutting roller. It is a figure which shows the arrangement|positioning relationship of a cutting blade with. Symbol A is a syringe crusher, which has a base frame 20 and a base frame 2.
The cutting section 1 compresses and cuts a syringe, injection needle, drip needle, etc. attached to the syringe 0, and a drive motor M. The base frame 20 is a metal frame body with casters 4 at its lower part, and side plates 11 and 11a are erected at the upper part of the base frame 20 at a required interval. A charging chute 1 is installed at the top of the side plates 11 and 11a.
9 has been installed. The input chute 19 is equipped with a sprayer (not shown), and the required amount of disinfectant (a mixture of disinfectant, deodorant, anticorrosion agent, etc.) is applied.
It can be sprayed into the syringe into which the liquid is injected. Below the input chute 19, four pairs of rollers are supported by bearing members 12, 12a, 13, 13a and bearing members 18, 18a attached to the outside of the side plates 11, 11a. The first stage is the feed roller 14, the bearing member 12,
Rollers 141 and 14 are arranged in parallel and supported by rollers 12a.
2, and a circumferential groove 158 is continuously formed in each of the rollers 141 and 142. The rollers 141 and 142 are eccentric, and the gap between the rollers 141 and 142 changes as it becomes wider and narrower during rotation. The second stage is a compression roller 15, bearing member 13,
Roller 15 is pivotally supported on the upper stage of roller 13a and arranged in parallel.
The rollers 151 and 152 have circumferential grooves 158 continuously formed therein similarly to the rollers 141 and 142. Although the rollers 141, 142, 151, and 152 have hook grooves 143 evenly distributed at four locations in the axial direction, the number thereof is not particularly limited and may be set as appropriate. The gap between the rollers 151 and 152 is set to be narrow so that the syringe can be compressed for smooth subsequent cutting. In addition, roller 15
The relationship between the circumferential grooves 158 and the convex portions 159 of No. 1,152 are opposite to each other, as shown in FIG. (The rollers 141 and 142 have a similar structure.) According to this, the syringe, etc. is sent to the next cutting roller 16 in an upright state by the facing grooves 158, so that the syringe can be placed diagonally or sideways. More cutting points can be obtained than in the case of cutting, and sufficient cuts can be made. The third stage is the upper cutting roller 16, and the bearing member 1
It consists of a smooth roller 161 and a cutting blade roller 162 which are pivotally supported and arranged in parallel at the lower stage of the rollers 3 and 13a. The smooth roller 161 has a cylindrical shape with a smooth peripheral surface.
The cutting blade roller 162 has a required number of cutting blades 1 on its circumferential surface.
63 is formed to protrude substantially parallel to the axial direction. The tip of the cutting blade 163 and the circumferential surface of the smooth roller 161 are in contact with each other or have a slight gap therebetween. That is, since the smooth roller 161 has a smooth circumferential surface, there is no misalignment between the circumferential surface of the smooth roller 161 and the cutting edge of the cutting blade 163 of the cutting blade roller 162, so that cutting is performed reliably. The fourth stage is the lower cutting roller 17, and the bearing member 1
8, 18a and rollers 171 arranged in parallel,
Consists of 172. One is a smooth roller 171, which has a cylindrical shape with a smooth peripheral surface. The other roller is a cutting blade roller 172, and a required number of cutting blades 173 are formed on the circumferential surface of the roller 172 in the circumferential direction. Further, the peripheral surfaces of the tip of the cutting blade 173 and the outer periphery of the smooth roller 171 are in contact with each other or have a slight gap therebetween. The cutting blade 163 formed on the cutting blade roller 162 of the upper cutting roller 16 and the lower cutting roller 17
The cutting direction of the cutting blade 173 is substantially perpendicular. Therefore, even a relatively large object to be crushed, such as a Ringer's solution container, will be cut into small lattice shapes. Note that a gear 16 is attached to the shaft end of the cutting blade roller 162.
9 is attached and is driven by a drive gear 170 of a drive motor M installed at the top of the base frame 20. In addition, each roller 141, 142, 151, 15
2, 171, and 172 are adapted to rotate inwardly by a series of gear transmission mechanisms G. Note that the rotational speed of each roller can be set arbitrarily. A lower chute 190 is installed below the lower cutting roller 17, and a receiving box 3 is provided below the chute 190. (Operation) The operation of this embodiment will be explained. (1) Activate the drive motor M, and put the syringe attached to the needle and other items to be crushed into the input chute 19 as appropriate. In addition, when only the injection needle is to be crushed, a injection needle chute with a small discharge port is arranged inside the input chute 19 so that the injection needle can stand up and fall easily. (2) The inserted syringe or the like is sent to the compression roller 15 below by the sending roller 14 which rotates eccentrically. At this time, the distance between the feed rollers 14 changes from widening to narrowing, so that large and small syringes, Ringer's liquid containers, etc. can be caught without difficulty. In addition, particularly large items such as Ringer's liquid containers are compressed to some extent by this and sent to the next compression roller 15. (3) A syringe or the like is set up in the circumferential groove 158, compressed by the compression roller 15, shaped into a flat shape so as to be easily cut, and sent to the upper cutting roller 16 below. (4) The sent syringe or the like is cut into long pieces by the upper cutting roller 16. That is, one smooth roller 16
1 has a smooth circumferential surface, so smooth roller 1
61 and the cutting edge of the cutting blade 163 of the other cutting blade roller 162, there is no misalignment or the like, so cutting can be performed reliably. (5) Next, the object to be cut is again cut in the width direction by the lower cutting roller 17, cut into a fine grid pattern, and sent to the receiving box 3 through the lower chute 190. The crushed materials stored in the receiving box 3 are then disposed of or incinerated. FIG. 5 is a sectional view of main parts showing another embodiment of the present invention. The difference from the above embodiment is that the third stage cutting roller and the fourth stage cutting roller are arranged in opposite directions. In other words, the third stage cutting roller has an arbitrary number of cutting blades 173 formed circumferentially on the outer periphery, and the fourth stage cutting roller has an arbitrary number of cutting blades 173 formed on the outer periphery in the axial direction. Cutting blade roller 1 formed with an arbitrary number of cutting blades 163
62 was used. The rest is the same as the previous embodiment. Note that the present invention is not limited to the illustrated embodiment, and the series of operations described above can be automated using various known techniques. That is, when a syringe is introduced into the injection chute 19, this is sensed by various switches and sensors, and the drive motor M is powered on. Then, the timer is activated for an arbitrary period of time (10 seconds) to crush the syringe. In addition, when any of the rollers becomes locked and a load is applied, the power is automatically turned off so that the operation can be stopped. As described above, the present invention can be modified in various ways within the scope of the claims for utility model registration.

[Effect of the idea]

The present invention has the above configuration and has the following effects. The loaded syringe, etc. is sent to the compression roller below by the eccentrically rotating feed roller, but at this time, the distance between the feed rollers changes by widening or narrowing, so the size of the processed material is Can easily hold used syringes, Ringer's solution containers, etc. of different sizes. Further, since the smooth rollers of the upper cutting roller and the lower cutting roller have smooth peripheral surfaces, the cutting edge of the cutting blade of the cutting blade roller does not shift, so that cutting can be performed reliably. Furthermore, the cutting directions of the upper cutting roller and the lower cutting roller intersect,
As a result, the processed material is cut into small pieces. Therefore, used syringes and the like can be promptly crushed to make them unusable, and problems such as promoting the spread of stimulants can be prevented.
