Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crusher for crushing syringes, injection needles, drip needles, etc.

[Conventional technology 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 Publication No. 51-33813 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 It cannot bite into the syringe, and only moves on the pressure roller, making it practically unusable as a crusher that needs to process syringes of multiple sizes.

[Purpose of invention]

An object of the present invention is to provide a syringe shredder that can promptly dispose of used syringes of different sizes to render them unusable.

[Structure of the idea]

The structure of the present invention taken to achieve the above object is as follows. That is, the present invention includes: an input chute; a feed roller disposed below the input chute and arranged in parallel at a required interval; a compression roller that compresses the material to make it easier to cut; a cutting roller that is placed below the compression roller and that cuts the syringe, etc.; and the feed roller rotates to change the distance between the two rollers. One or both of the rollers are eccentrically provided so that the cutting roller has a smooth circumferential surface;
Consists of a cutting blade roller with cutting blades formed on the circumference,
The smooth roller and the cutting blade roller are crushers, such as syringes, in which the smooth surface and the cutting blade are arranged so that they are in contact with each other or are spaced apart from each other by a small distance.

〔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, and FIG. 3 is a diagram showing the arrangement of the feed rollers.

Symbol A is a device for crushing syringes, etc., which compresses syringes, injection needles, drip needles, etc. to make them easier to crush.
It includes a cutting section 1 for cutting, and a crushing section 2 for crushing syringes and the like.

Cutting Section Side plates 11 and 11a are erected at the upper part of the base frame 20, which is a metal frame body, at a required interval. A charging chute 19 is installed at the top of the side plates 11, 11a. The input chute 19 is equipped with a sprayer (not shown), which allows a necessary amount of disinfectant (such as a mixture of sterilizing, deodorizing, and anticorrosive agents) to be sprayed into the syringe. Below the input chute 19, three pairs of rollers are mounted on the side plate 11,
11a.

The upper stage is the feed roller 14, which is made up of rollers 141 and 142 arranged in parallel, each of which has a continuous circumferential groove 158 formed therein. The rollers 141, 142 are provided eccentrically, and the distance between the rollers 141, 142 changes during rotation. Although the rollers 141 and 142 are formed with hook grooves 143 distributed evenly at four locations in the axial direction, the hook grooves 143 are not limited thereto and may be set as appropriate.

The middle stage is a compression roller 15, and bearing members 13, 13
Rollers 151, 1 are pivotally supported and arranged in parallel on the upper stage of a.
Consists of 52. The rollers 151 and 152 have a circumferential groove 1.
58 are formed continuously, and the hooking grooves 143 are formed at four locations evenly distributed in the axial direction, but this is not limited and may be set as appropriate. roller 15
The gap between 1 and 152 is narrowed to allow compression of the syringe for smooth subsequent cutting. In addition, roller 1
The relationship between the circumferential grooves 158 and the convex portions 159 of 51 and 152 is, as shown in FIG. 3, opposed to each other. (The same applies to the rollers 141 and 142.) According to this, the syringe, etc. is placed in a standing state by the opposing circumferential grooves 158 and sent to the next cutting roller 16, so a larger number of cutting points can be obtained and sufficient cutting can be achieved. I can do it.

The lower stage is the cutting roller 16, and the bearing members 13, 13
Smooth roller 16 that is pivotally supported and arranged in parallel at the lower stage of a

Reference numeral 61 has a cylindrical shape with a smooth circumferential surface. The cutting blade roller 162 has a required number of cutting blades 163 on the circumferential surface.
is formed so as to protrude substantially parallel to the axial direction. Is the distance between the tip of the cutting blade 163 and the circumferential surface of the smooth roller 161 small?
I'm touched. That is, since the smooth roller 161 has a smooth circumferential surface, the gap between the circumferential surface of the smooth roller 161 and the cutting edge of the cutting blade 163 of the cutting blade roller 162 does not cause misalignment, so that cutting can be performed reliably.

FIG. 4 is a front view showing another embodiment of the cutting blade. The cutting blade 169 of this embodiment is formed in a serrated shape in the width direction, and can sufficiently cut the syringe or the needle even if it falls sideways.

A gear 169 is attached to the shaft end of the roller 162, and is driven by a drive gear 170 of a motor M1 installed at the top of the base frame 20.

In addition, each roller 141, 142, 151, 15
2, 161, and 162 are rotated in opposite directions by a transmission mechanism G using a series of gears.

Note that the rotational speed of each roller can be set arbitrarily. A lower chute 17 communicating with the crushing section 2 is installed below the cutting roller 16.

Crushing Section An installation stand 21 is provided in the middle part of the base frame 20. A motor M2 is installed on the installation stand 21, and a crushing device 22 is adjacent thereto. Furthermore, casters 4 are attached to the bottom of the base 20.

The crushing device 22 includes a horizontally placed drum body 23,
The rotating body 25 is arranged at the center of the drum body 23 and has a required number of crushing blades 24.

An inlet 26 communicating with the lower chute 17 is provided in the upper part of the drum body 23 . Further, a discharge port 27 is provided at the bottom of the drum body 23.
The discharge port 27 is equipped with a grid-shaped fixed blade 28.

The inner wall of the drum body 23 is slightly larger than the rotation locus of the cutting edge of the crushing blade 24, and has a shape that does not make contact with it.

Then, the rotating body 25 is connected to the gear 20 by the motor M2.
1,202.

Note that a receptacle 3 that can be pulled out is installed below the discharge port 27.

(effect) The operation of this embodiment will be explained.

(1) Activate motors M1 and M2 and insert the syringe with the needle attached into the injection chute 19.

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 is sent to the compression roller 15 below by the sending roller 14 which rotates eccentrically. At this time, the inner distance between the feed rollers 14 changes from widening to narrowing, so that whether the syringe is thick or thin, the syringe can be bitten easily.

(3) The syringe is compressed by the compression roller 15, shaped into a slightly flat shape so as to be easily cut, and sent to the cutting roller 16 below.

(4) The sent syringe is cut by the cutting roller 16. At this time, since the smooth roller 161 of the cutting roller 16 has a smooth circumferential surface, the distance between the circumferential surface of the smooth roller 161 and the cutting edge of the cutting blade 163 of the cutting blade roller 162 is such that no misalignment occurs, so that cutting is possible. It will definitely be done.

Then, the cut syringe is placed in the lower chute 1.
7 to the crushing device 22.

(5) When the cut syringe is sent by the crushing blade 24 and falls from the outlet 27, the crushing blade 24
and the fixed blade 28, and are crushed, cut into smaller pieces, and stored in the receiving box 3. The contents are then disposed of or incinerated.

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 motors M1 and M2 are turned on. Then, the timer is activated for an arbitrary period of time (2 to 3 minutes) 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, various modifications are possible within the scope of the claims for utility model registration.

[Effect of 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 inner sides of the feed roller changes as it becomes wider or narrower, so it is difficult to detect whether the syringe is being processed or not. No matter how thick or thin the syringe is, you can bite into it without any difficulty. Further, since the smooth roller of the cutting roller has a smooth circumferential surface, the distance between the cutting roller and the cutting edge of the cutting blade will not be misaligned, so that cutting can be performed reliably. 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.
