DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used for treating a used injection needle for medical use, and is used for a syringe or a wing-shaped needle for drip used by being fitted or screwed to a tip of a holder. The present invention relates to a processing device for removing a needle that is no longer needed after use from a holder and disposing the needle, and more particularly, to a device of a type in which the needle is burned off.

[0002]

2. Description of the Related Art Until now, injection needles have been frequently used for various types of business, for example, medical use and experimental research, and industrial sewing needles and general sewing needles have been frequently used for sewing. When these needles are discarded, most of them are collected without any special processing, and are disposed of as industrial waste by treating them as they are in a dedicated disposal site by packing them in a cardboard box, bag, or the like. Some of them are mixed with general waste and discarded without any safe processing, which is a major social problem.

[0003] Disposable injection needles are widely used and used in large quantities for safety from the viewpoint of epidemic prevention, and as a result, a large amount of injection needle dust is generated and safety measures are not thoroughly implemented. Injury accidents, such as when a disposal company passes by during the disposal process and stabs a finger or the like, are not stopped. This accident may lead to serious accidents such as blood infections caused by hepatitis B virus, C virus adhering to the needles, etc. Therefore, it is instructed to pay close attention to disposal. As a safety measure in the disposal, a bulky but non-piercing syringe holder part and a dangerous injection needle are separated, and especially only the injection needle is thoroughly managed and safely disposed of. As the separation method, there are a method in which a nurse pulls out with a finger and a method in which the separation is performed mechanically using a processing tool.

[0004] In the former case, it is inevitable that the hand is slid and the fingers are stabbed during processing, or the fingers are dropped and stabbed in the feet, etc., which is more dangerous than another case. The nature was high. In the latter case, as a simple method, a guide hole is provided in the box body, the hole is formed so that the connection base of the injection needle can be hooked, and a device to be hooked and removed by the removal hole is a real opening flat 3-88548. Many proposals have been made and provided. This type which is simply inserted into the removal hole and removed can be used for the type in which the injection needle is fitted to the syringe holder, but the type which is screwed in does not come off simply by trying to withdraw. So could not be used.

[0005] In order to remove even the screw-in type, the base of the injection needle is formed so as to be pressed into the removal hole, and the holder is rotated by hand to remove it (Japanese Patent Application Laid-Open No. Hei.
9) was proposed. However, rotating the holder one by one was a rather cumbersome operation even if it seemed easy. Therefore, as a further improvement of the method, a method has been proposed in which the base of the injection needle is rotated and removed with power while holding the holder (Japanese Patent Laid-Open No. 3-76). However, although the above-mentioned method makes it easy to remove the needle tip, the needle tip itself remains sharp and sharp, so that it is still not possible to prevent an accidental injury caused by a finger or the like during the disposal process. In addition, a device that mechanically bends the needle tip and pulls out (Japanese Utility Model Laid-Open No. 2-111448) is proposed. In the case of this processing, even if the needle is bent and it is possible to reduce the piercing in a straight line, the tip of most needles remains sharp and sharp.

[0006] For this reason, there has been proposed an injection needle processing apparatus in which the needle tip is burned off and processed as proposed in JP-A-60-5155. Here, injury accidents can be prevented at last. However, this device has many problems as follows. (1) Screw-type screw-off processing cannot be performed. (2) Processing cannot be performed with only one hand. (3) Since the used portion of the electrode is always at the same position, if the melt melted and deformed by the electrode is easily fixed to the needle tip and is to be pulled out, the melt will not be caught by the electrode or will be damaged. (4) The molten material solidifies and adheres to the electrode, thereby preventing the current from flowing and preventing the burnout. (5) It is difficult to insert the needle tip into the electrode. As described above, there are many difficulties as described in (1) to (5), and it has not been used until now because it is extremely difficult to use.

[0007]

[0013]

According to the present invention, the needle S has a high temperature of about 800 ° C. when the needle S is burned off in the needle burning-off mechanism 2, so that the tip T of the needle S is melted and sterilized. Therefore, the needle is less likely to be stabbed, and even if the stab is stabbed, the needle is sterilized, so that infection with a virus or the like does not occur. With the nurse holding the syringe holder H, the needle S is first burned off by the needle burning mechanism 2, and then the needle S is guided to the needle dropping mechanism 3 to separate and drop the needle S from the holder H. Can be done continuously with one hand. This processing work can be performed on all of various injection needles having different forms.
That is, in the case of the needle tip screw type, the needle dropping mechanism 3 for rotating, in the case of the fitting type, by the fitting type needle dropping mechanism 23, and in the case of the winged needle, the needle tip insertion guide 1
6 can be inserted into the insertion guide hole 34 and processed. Anyway,
Even when the needle tip insertion guide 16 is removed, since the fixed electrode 8 and the opening / closing electrode 9 of the upper electrode 7 have the same polarity, there is no danger of electric shock, and it is safe to touch the finger. After burning out, it is thrown into the winged needle feeding hole 26.

Also, unlike the melting by the conventional one-point insertion type electrode, the electrode portion of the present invention has a long parallel electrode and dissolves the needle contact point while sliding the inclined surface 11, so that the melted material is formed by the needle tip. There is no risk that the molten material will be rubbed off from the electrode and be caught or caught in the electrode and will not damage the electrode. Further, since the melt does not adhere to the electrodes, normal energization is ensured. In addition, since the electrode S is melted while moving the electrode contact point from the tip T of the needle S toward the base, a range melting process from the tip T to the base can be performed. When the needle S is inserted into the electrode, the needle S is guided by the needle tip insertion guide 16 so that the needle can be reliably set even if the needle is roughly inserted. Further, since one of the upper electrodes 7 is the opening / closing electrode 9, the holder H Can be easily inserted into the groove 30 of the upper electrode 7 with a margin even if it is slightly inclined.

[0015]

[Usage] To use the present invention, you need a power supply,
The battery 35 is charged in advance for carrying around. The processing procedure after using the syringe is holder-H
The use portion is selected and performed according to the form of the connection base K between the needle and the needle S. In the case of the screw-on type, while the nurse holds the syringe holder-H, the needle tip is first inserted into the needle tip insertion guide 16 as shown in FIG. 8, and further as shown in FIGS. 4 and 5. Next, the needle S is burned off while being moved while being pushed down along the insertion guide groove 17. When inserting the needle tip,
Since the guide is guided by the needle tip insertion guide 16, it can be securely set even if the needle tip is roughly inserted. Further, even if the holder-H is slightly shifted or inclined by the opening / closing electrode 9, there is enough space between the fixed electrode 8 and the opening / closing electrode 9. Can be inserted into Next, FIG.
As shown in (1), the needle connecting base K is placed on the needle guiding groove 4a and passed therethrough. The needle connecting base K is guided to the needle dropping mechanism 3 shown in FIG. 10 and the needle connecting base K of the holder H is pressed against the drive switch plate 21. Then, the connecting base K of the needle S rotates and comes out of the holder-H. Then, if it is made to slightly back from the holding portion 19 and is returned to the wide introduction groove 18, it falls into the falling needle storage portion 5 from the dropout hole 31 thereunder. All of these steps can be performed continuously while holding the holder H with one hand.

In the case of the fitting type, the same process as in the case of the screw type is performed until the needle S is burned off. Then, as shown in FIG. 9, when the needle S is inserted into the stop groove 24 of the fitting type needle dropping mechanism 23, the needle S is held by the inclined surfaces 25 on both sides thereof.
It is pushed away from H and falls off. In the case of a winged needle, the needle tip insertion guide 16 is connected to the winged needle insertion guide 37.
In this case, the needle can be inserted directly between the fixed electrode 8 of the upper electrode 7 and the opening / closing electrode 9 with the wings, and sufficiently burned off. At the time of replacement, even if the fixed electrode 8 and the opening / closing electrode 9 are exposed, they have the same polarity, so that there is no danger of electric shock even if a finger comes into contact, and it is safe. After being burned out, it is pulled out and put into the winged needle input hole 26 shown in FIG. When the burned-out needles accumulate in the falling needle storage part 5, the needles are put into another container or the like and disposed of.
