Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection needle processing device.

[0002]

2. Description of the Related Art A used injection needle may come into contact with blood, which may cause blood infections such as AIDS and hepatitis. There is a risk of contacting and injuring many people. Therefore, it is difficult to avoid the accident because the shape of the injection needle is easily pierced by itself, though the treatment requires careful attention.

For this reason, at least the tip of an injection needle is destroyed immediately after use to prevent it from being pierced. As the device, for example, Japanese Patent Laid-Open No. 2-13
In No. 456, when the injection needle is inserted into the hole, it reaches a spot welding device in which a pair of positive pressure contactor and negative pressure contactor for discharge are installed to face each other, and discharge when the needle tip is pressed down. It is heated red by and is crushed between both pressure contactors.

Further, in Japanese Patent Laid-Open No. 193052/1993,
It is configured such that an electric current is passed while the tip of the injection needle is in contact with the electrode to melt the tip. Japanese Unexamined Patent Publication No. 3-254747 proposes a structure in which an arc-shaped guide surface is formed on an electrode portion with which the needle tip hits, so that the needle tip is rounded.

Further, US Pat. No. 5,138,124 proposes a structure in which one of the electrodes is rotated and the needle is pressed against the rotating electrode so that an electric current is caused to flow to destroy the needle.

[0006]

In any of the above constructions, an injection needle is inserted, and an electric current is caused to flow by contacting the injection needle between the electrode terminals, and the injection needle is pressed against one of the electrode terminals. It is common in that it has a structure that electrically destroys the tip of the.

However, in any of the techniques, the distance between the two electrode terminals is constant and fixed,
Only the tip of the injection needle, that is, the sharp tip is destroyed. Further, in Japanese Patent Laid-Open No. 3-254747,
The tip of the injection needle has a structure that can be bent in a spiral shape.

In the former case, it can be said that the sharp tip is destroyed, most of the long injection needle remains, the blood contacting part is as it is, and the shape of the broken tip is not safe. However, there is a risk that the skin of hands and fingers will be damaged.

Also in the latter case, it is difficult to form a shape in which the sharp tip portion is neatly wound and the skin is not damaged. Therefore, in any case, it must be said that in the post-use treatment of the injection needle, the treated injection needle may cause damage to the skin.

[0010]

Therefore, in the present invention,
By destroying not only the sharp part of the tip of the injection needle, but also most of the injection needle, and leaving only the fitting part to the syringe barrel and the root part of the injection needle, By eliminating the part that damages the skin of the injection needle and making it smaller, it is safe and easy to dispose of,
