Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a device for crushing used syringes.

"Prior Art" Conventional syringe and needle crushing devices are high-speed crushers using rotating blades. Therefore, not only was there a lot of noise, but it was also difficult to cut off a single syringe and needle immediately after use. Therefore, the inventor of the present invention conducted an experiment in which a single syringe inserted into the syringe descending guide gutter was stopped by a stopper, and in that state, the syringe in the gutter was cut by a reciprocating shear blade, but the syringe was cut by the thickness of the shear blade. tries to shift downward, but because the stopper prevents the shift, the cutting part between the shear blade and the stopper is deformed, which not only requires a large force to deform, but also prevents the cutting from occurring smoothly. caused a problem.

``Problems to be solved by the invention'' This invention involves inserting a single disposable syringe and/or needle (in the case of a glass syringe) into the gutter immediately after use, holding it in the gutter with a stopper, and then shearing it back and forth. The purpose of the blade is to cut smoothly with less force.

``Means for Solving the Problems'' In order to achieve the above objectives, this proposal provides a syringe descending guide gutter inside the machine case, a syringe cutter with a fixed blade and a reciprocating shear blade is provided at the lower end of the gutter, and the cutter A syringe lowering stopper formed by a spring plate is provided below the syringe with a gap therebetween, and the stopper lowers slightly against the elasticity due to the downward pressure of the syringe, and returns to its original state due to the elasticity when the downward pressure is released. Consists of a syringe crusher.

"Function" Therefore, when the disposable syringe 2 and/or the injection needle 3 are put into the guide trough 4 immediately after use, the syringe 2 and the injection needle 3 are stopped by the stopper 8 and held in the guide trough 4. Ru. In this state, the syringe 2 and the injection needle 3 are cut by the cutter 7 by reciprocating the reciprocating shearing blade 6 once or multiple times. At that time, the blade surface of the blade 6
The cut part (syringe needle 3 or syringe 2) located at the distance t between the stopper 8 and the stopper 8 receives the downward pressure and moves downward slightly, but the stopper 8 resists the elasticity due to the downward pressure and moves away from the solid line position in Figure 3. It lowers slightly to the position shown by the imaginary line in the same figure, returns to its original position (solid line position in Figure 3) due to elasticity when the downward pressure is released upon completion of cutting, and the above-mentioned cut part repeats the action of falling from the interval t. The syringe 2 and needle 3 are then cut into multiple parts.

Since the glass syringe is used repeatedly, only the used injection needle 3 is cut as described above.

Embodiment A syringe lowering guide trough 4 and a syringe needle lowering guide trough 4' are provided in an inclined manner inside a machine case 1 having a syringe table 9' at its upper end. A fixed blade 5 is attached to the lower end of the gutter 4, 4'.
A cutter 7 for the syringe 2 and the injection needle 3 is provided with a reciprocating shearing blade 6. This cutter 7
A lowering stopper 8 for the syringe 2 and the injection needle 3 is disposed below the syringe 2 and the syringe needle 3 at a distance t so as to be openable and closable, and one end of the stopper 8 is supported on the output shaft 10 of the reciprocating solenoid 9. It can be opened to the virtual line position and closed to the original solid line position.
The shearing blade 6 is connected to a crank 12 via a connecting rod 11, and the crank 12 is provided on the output shaft 14 of a motor 13 for one or more rotations, and the crank 12 is rotated one or more times. can be moved back and forth to cut the injection needle 3 and syringe 2 held by the stopper 8 in the gutter 4 or 4'. The stopper 8 is slightly lowered by the spring plate against the downward pressure of the cut portion by the shearing blade 6, and returns to its original position after the cutting is completed. The stopper of the guide trough 4' of the injection needle 3 may be a rigid stopper. In addition, what is indicated by 4'' in the figure is the inlet of the syringe descending guide trough 4,
4'' is an inlet of the syringe needle descending guide trough 4', 15 is an opening/closing plate for the inlet 4'', 16 is an opening/closing motor, 17 is a guide on both sides of the shearing blade 6, and 18 is a rising prevention plate for the stopper 8. , 19 is a hinge for raising and lowering the stopper 8, and FIG. 4 is a longitudinal sectional view of another embodiment of the gutter 4.
20 is a power switch, and 21 is an operation switch.

``Effect of the invention'' Since the present invention is configured as described above, only the syringe with needle 2 or the syringe needle 3 can be fixed with a small force immediately after use.
It has the advantage of being able to cut each piece smoothly, preventing noise, and miniaturizing the mechanism and prime mover.
