Abstract

PURPOSE:To make processing of an object to be processed, for example used injection needles, safely and simply and eliminate anxiety of secondary infection by igniting the tip of the object to cause melting or deformation so that it can no more be used and at the same time, performing high temp sterilization. CONSTITUTION:To dispose of an injection needle 2 fitted on an injector 1, it 2 is inserted in a hole in a guide 4 formed at the top surface of a case 21. At the time, an electrode pushing rod 11 is intruded into the case 2, and an electrode 6 mating with the tip of the rod is set in the condition as pushed back against the action of a spring 7 so that insertion of the injection needle 2 is facilitated. After insertion of the injection needle 2, intrusion of the rod 11 is disengaged, and the electrode 6 is put in pressure contact with the injection needle 2 by the force of the spring 7, or otherwise, another electrode 13 is advanced by screw so that it contacts the injection needle 2. Current is fed to electrode in the condition that either of the electrodes 6, 13 is in contact with the injection needle 2 as described, and the needle 2 is heated, melted, and deformed, and at the same time sterilization is performed, and the processed needle 2 is accommodated in a drawer 22.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention safely and conveniently treats injection needles and therapeutic needles used for medical treatment.

[0002]

2. Description of the Related Art In order to prevent infections such as so-called AIDS (Congenital Immunodeficiency Syndrome), single-use disposable syringes have become popular. It was sometimes discarded.

There is also a method of completely preventing misuse two or more times, such as breaking the needle immediately after use, but there is a risk that the needle may get stuck in a finger or a secondary infection may occur.

[0004]

[Problems to be Solved by the Invention] Immediately after use, the needle tip or the entire needle is safely and conveniently heated to completely prevent misuse two or more times, and high temperature sterilization prevents accidents caused by used injection needles and therapeutic acupuncture needles. It is an attempt to make it absolutely.

[0005]

The present invention will be described with reference to the drawings. According to a concrete embodiment as shown below, the tip (3) of the needle (2) or the entire needle-shaped portion is instantly supplied with electric power or the like. It is made unusable or easy to identify and sterilized by heating and melting or deforming or discoloring it at high temperature.

【Example】

[0006] For example, a guide (4) for easily inserting the needle (2), an electrode A (6) made of carbon or metal for elastically contacting the needle-shaped portion to conduct electricity, and a tip (3) of the needle ) Is provided in contact with or in proximity to the electrode B (13) for discharging or energizing.

As an example for pushing back the electrode A (6) to secure the passage of the needle (2) when the needle (2) is inserted, an electrode push rod () having an elongated U-shaped groove (9) is provided. 1
1) should be provided.

Alternatively, if the hole (5) of the guide (4) into which the needle (2) is inserted can be elastically expanded and contracted so that it can be energized by making strong contact with the needle-like portion, electrode A (6)
Can be omitted.

The bearing (14) is used in order to avoid wear and insulating film due to repeated use of the same part of the electrode B (13).
It is attached to the electrode feed screw rod (15) having the inner diameter of the female screw by a replaceable nut (16) and the electrode feed knob (17) is turned to enable rotation and forward movement.

In order to prevent the electrode feed screw rod (15) from reversing and retracting, the bearing (14) is combined with the ratchet (18).

As an example of simplifying the structure and facilitating the insertion of the needle (2), the hole (5) of the guide (4) is made slightly larger, and an electromagnetic induction coil (20) surrounds the hole (5), and the inserted needle ( Secondary power may be induced in 2).

[0012]

In the example using the electrode A (6), the guide (4)
When the electrode push rod (11) is pushed when inserting the needle (2) into the needle, the elongated U-shaped groove (9) advances along the guide pin (10), pushes back the electrode A (6), and the groove ( 9) serves as a passage for the needle (2), and when the electrode push rod (11) is released, it returns to the stopper ring (12), and the electrode A (6) is pushed by the spring (7) and strongly contacts the needle (2). Do

In the case of using the electrode B (13), when the electrode feed knob (17) is turned, the electrode B (13) is also rotated by one tooth of the ratchet (18), and the electrode feed knob (17) is turned to 1.
When rotated, the electrode B (13) turns the electrode feed screw rod (1
By advancing by one tooth of the bearing (14) together with 5), even if the same portion is repeatedly used and wear or an insulating film occurs, it is possible to shift the position and use a good electrode surface.

When the good electrode surface is used, the nut (16) can be removed and the electrode B (13) can be easily replaced.
Free the ratchet (18) and the electrode feed knob (1
7) Turn to restore the electrode feed screw rod (15) to the starting position.

When instantaneously heated by electric power or the like, the sharp tip (3) burns and melts and deforms earlier than other parts. A wide range of the needle-shaped portion is heated to a high temperature due to electric resistance or conduction, and is deformed or discolored, and is sterilized simultaneously.

In the case of utilizing electric energy such as energization, discharge or dielectric, it can be sufficiently heated with a low voltage or a small current, and if a known technique such as storing electricity in a capacitor for intermittent use is applied, a power source can be used. Is commercial 10
It may be 0 volt or less, and may be a desktop type or other small device that is easy to carry.

[0017]

[Effect] According to the present invention, a used injection needle or a therapeutic needle can be safely and simply processed immediately after use.

It becomes unusable or easy to distinguish by melting or deforming or discoloring, and it is possible to completely prevent misuse of two or more times.

By high temperature sterilization, there is no risk of secondary infection, and all accidents involving used injection needles and therapeutic acupuncture needles, including after disposal, can be eliminated.
