Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher for used medical device waste such as a syringe and a filter for artificial dialysis.

2. Description of the Related Art Used medical devices such as injection needles and filter catheters for artificial dialysis are all disposed of in order to prevent secondary infections such as hemophilia and hepatitis B. However, this disposal is mainly buried in the ground, but recently incineration at a high temperature has also been performed, but air pollution due to smoke exhaustion has become a problem.

[Problem to be Solved by the Invention] Since this medical waste is a large amount and reaches as much as three 4t trucks a month at large hospitals, it is considered to reduce the amount by grinding once. However, filters for artificial dialysis use a polypropylene-based hard resin, so it is usually inefficient with a crusher for molding wood chips, and since they are accompanied by rubber tubes and bandages, they are entangled and crushed. It was impossible.

SUMMARY OF THE INVENTION According to the present invention, a blade is put in a rotating body of a conventional crusher and rotated to cut tangled rubber tubes, bandages and the like, thereby enabling crushing. .

The hammer used in this crusher is a free hammer that is freely suspended around the mounting shaft.
Since it is swung by the rotating centrifugal force, even if an accident such as a rubber tube or bandage entangles and the rotation of the main body stops, the hammer is reversed by the impact of this stop and attached to the hammer. The tangled rubber tube, bandage and the like can be cut by the blade, and the main body of the crusher starts rotating again. In addition, in the crusher of the present invention, not only the blade is planted on the hammer mounting shaft, but also the cutting edge of the fixing plate of the hammer mounting shaft is provided with a blade-shaped cut to efficiently cut rubber tubes and bandages which are easily entangled. Can do well.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing a mounting structure of a hammer (1) of a crusher body A, (1) is a hammer, and (2) is a hammer mounting. Show the axis. (3) is a fixing plate of the hammer mounting shaft, and (5) is a rotating shaft. Therefore, the engine rotates at a high speed as indicated by an arrow by driving the engine. FIG. 2 is a side view showing the configuration of the hammer (1), in which a slightly larger through hole (4) is formed at the tail end of the hammer (1), and the through hole (4) has a smaller diameter. The hammer mounting shaft (2) is inserted, and the hammer (1) is loosely attached to the mounting shaft (2). (10) is a blade at the tip of the hammer, and (6) is a blade drilled on the side surface of the hammer. Therefore, the hammer (1) normally rotates as indicated by an arrow X by the rotation of the rotation shaft (5). And this hammer (1)
Is suspended on the rotating shaft (2), so that if the rubber tube or bandage becomes entangled during the grinding and the rotation is suddenly stopped, the impact of this stop causes the hammer (1) to reverse as shown by the arrow Y. By action, the entangled rubber tube or bandage can be cut by the blade (6) and the rotation is started again. FIG. 3 is a front view showing a state in which the hammer (1) is mounted on the hammer mounting shaft (2), and (7) shows a cutting tool implanted on the hammer mounting shaft (2). FIG. 4 shows a fixed plate of the hammer mounting shaft (2), which is a disk fixed to the rotating shaft (5), and provided with an edge-shaped notch (8) at several places on the periphery thereof. Since the medical device waste crusher of the present invention is based on the above structure, synthetic resin products and glass products such as syringes and filters for artificial dialysis are crushed and crushed by the impact of a hammer. Most of the attached rubber tube, bandage, etc. are rotated in the normal X direction, and the blade (6) provided on the side surface of the hammer (1) and the blade (7) implanted on the hammer mounting shaft (2). ) And the blade-shaped notch (8) provided on the periphery of the hammer mounting shaft fixing plate (3), but the rubber tube, bandage, etc. are entangled with the rotating shaft or the like and stop rotating. In this case, the hammer (1) suspended in a free state by the impact of the stop is inverted in the Y direction so that the hammer (1)
The rubber tube, bandage, etc., which are entangled by the blade (6) provided in the above, can be cut.

[Effect] The medical waste crusher of the present invention crushes waste equipment by hitting with a hammer by providing a blade in a rotating body and rotating as described above, and furthermore, a rubber tube or a bandage entangled with a rotating shaft. Crushing efficiency is very good because it can also be cut, and the amount of medical waste generated is large, so it is convenient to handle even when burying in the ground or when burning it The effect is extremely large in practical use.
