Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a syringe breaking device with a simple structure.

[Conventional technology]

Many syringes have been used in hospitals and the like, but most of them are disposable and made of plastic.

Therefore, most syringes are disposed of without being reused, but if they are disposed of in their original form, there is a risk that they may be reused by drug patients and encourage drug crimes. If such substances were attached to the syringe, there was a risk that it could be an intermediary for infectious diseases.

Furthermore, although it is possible to destroy the syringes each time with pliers or a hammer, it is very time-consuming when there are a large number of syringes, and there is a problem that this is practically impossible.

Therefore, for example, as described in JP-A-61-157371, a rotating rotor is provided in a machine casing having an input port at the top and a discharge port at the bottom, and the rotating rotor and the blade disposed inside the machine casing are connected to each other. has proposed a waste shredding machine that shreds syringes placed in a machine casing.

[The problem that the idea attempts to solve]

However, the machine for crushing waste products such as syringes and the like described in the above-mentioned publication had the problem that it could not be installed in hospitals and the like where the amount of waste used was small because the amount of crushing was large and the device was large.

The present invention was developed in light of these circumstances, and is a relatively small and simple device that destroys the needle and barrel of a used syringe so that they cannot be reused. The purpose is to provide.

[Means for Solving the Problems] The syringe breaking device according to the present invention, which meets the above object, includes a cam plate disposed inside a case and rotationally driven by a motor rotating at a low speed, and a cam plate driven by the cam plate. The syringe breaking device has a syringe needle cutting part and a syringe barrel breaking part each driven by a syringe, the cam plate being a disc-shaped cam plate whose rotation center is at an eccentric position, a first movable blade whose handle portion slides on one side of the cam plate and rotates back and forth;
The syringe barrel has a first fixed blade that is paired with the first movable blade and has a blade portion having a circular hole, and a guide portion that guides a syringe needle to the first fixed blade. The destruction portion includes a second movable blade whose handle portion slides on the other side of the cam plate and moves back and forth;
It has a second fixed blade that is paired with the second movable blade and is formed with a blade portion consisting of a slightly larger round hole, and the handle portion of the first movable blade and the second movable blade are connected to each other. It is constructed with a tension spring that connects the handle of the blade.

Here, the first and second fixed blades and movable blades of the syringe needle cutting part and the syringe barrel breaking part are preferably made of ceramic material, but are not necessarily limited to this, for example, made of stainless steel or It is also possible to use materials such as steel.

[Effect]

The syringe breaking device according to the present invention has a needle cutting part and a syringe barrel breaking part, and the needle cutting part and the syringe barrel breaking part each include a first fixed blade, a first movable blade, and a first movable blade. It has two fixed blades and a second movable blade. The first and second movable blades have their handles slidingly in contact with both sides of a disc-shaped cam plate driven by a motor rotating at a low speed, and are alternately moved back and forth by the rotation of the cam plate. Therefore, the ends of the syringe needle and syringe barrel inserted into the blade portions formed by the round holes of the first and second fixed blades can be cut alternately without a large load.

In addition, since the blade portions of the first and second fixed blades of the syringe needle cutting section and syringe barrel breaking section are formed into round holes, the entire blade is formed firmly, and the size of the round hole is adjusted to the size of the syringe needle. By appropriately forming the syringe to match the syringe barrel, it is possible to prevent fingers from getting stuck in the syringe.

[Effect of idea]

As is clear from the above description, in the syringe destruction device according to the present invention, the first movable blade of the syringe needle cutting section and the second movable blade of the syringe barrel destruction section are mounted on a rotating disc-shaped cam plate. Since the tension springs are placed on both sides and driven alternately, the load on the motor is light, and there is no need to worry about noise like with conventional crushers, allowing for smooth operation. Since the structure is simple, there are few failures and a long service life.

Further, since the blade portions of the first and second fixed blades are each formed with a round hole, the object to be cut will not escape. By adjusting the size of the round hole to the tip of the syringe barrel or the syringe needle which is the object to be cut, there is no chance of injury to fingers or the like due to getting stuck in the syringe during use.

Therefore, the syringe destruction device is extremely useful for disposing of small amounts of syringe needles, and by using this device, syringes used in hospitals etc. are destroyed so that they cannot be reused. It will not be used for crimes, and there will be no risk of transmitting pathogens, etc.
