て病原菌に感染する危険もあるし、能率も悪い。Conventionally, in order to protect medical personnel from the risk of being infected with pathogenic bacteria via used injection needles, various containers have been proposed in which the injection needle is pulled out from the syringe barrel and discarded, but these are both Press the container with one hand to fix it, and with the other hand hook the injection needle on this container and remove it from the syringe barrel.
It is dropped into a container for storage and disposal. Both hands must be used for use, there is a risk of accidentally touching the injection needle to be infected by pathogenic bacteria, and inefficiency.

る。(Construction of the Invention) The present invention integrally includes a hole portion having a size capable of inserting the needle base of the injection needle and a hole portion smaller than the thickness of the needle base in the chamber for accommodating the used injection needle. And the virtual plane including this hole intersects the bottom surface of the chamber in an inclined state, so that the injection needle inserted from the large hole portion is moved to the small hole portion side, and the needle tip of the syringe is While moving the piston pressing part on the opposite side downward, press the needle tip downward to squeeze the injection needle, do not touch the injection needle and press the container to fix it. Therefore, it is an object of the present invention to obtain a product that can be easily withdrawn with one hand without any risk, can be safely and efficiently processed without the risk of being infected by pathogenic bacteria.

以下実施例とともに述べれば、使用済みの注射針を収納

のであれば、更に適宜の材料を使用することができる。Speaking with the examples below, there is a means for withdrawing the injection needle of the chamber that houses the used needle, and this chamber is usually polypropylene, polyethylene, ABS resin, AS resin, vinyl chloride resin or other hard synthetic resin. It is preferably formed of a resin, but an appropriate material can be used as long as the discarded injection needle does not pierce or the drug solution does not exude and the pathogenic bacteria can be enclosed in the chamber.

抜取り操作ができて更に好ましいことが多い。Shown is a box-shaped chamber with a stepped upper part (1).
A neck (3) protruding from the upper rising surface (2) of
A substantially triangular extraction hole (4) serving as extraction means is formed at the tip of the neck. One side of this extraction hole is formed as a large hole through which the needle base (6) of the injection needle (5) can be inserted, and the other side is formed as a small hole smaller than the thickness of the needle base. . Virtual plane (7) where this extraction hole is located
Is inclined with respect to the bottom surface (8) of the chamber and intersects the bottom surface of the chamber. In this case, it is often more preferable to form the virtual plane so that the angle (α) with the bottom surface of the container is about 45 degrees or more, because an effective extraction operation can be performed with a compact chamber.

まま落下して収納される。When using this, hold the used syringe (9) in one hand, insert the injection needle through the hole with a large extraction hole until the needle base is hidden in the chamber, and then insert the needle base with a small extraction hole. The needle tip of the syringe comes into contact with this small hole portion. Then, by pushing the needle tip downward while moving the piston pressing portion on the side opposite to the needle tip of the syringe downward, the needle base of the injection needle is at the small hole portion of the extracting means. As it gets twisted, the injection needle loosens from the needle tip (10) of the syringe and falls out and is stored in the chamber as it is.

きる。As shown in FIG. 2, the withdrawal action when withdrawing the injection needle is such that an imaginary plane including the hole of the withdrawing means intersects the bottom surface of the chamber, and the imaginary plane is behind the front end of the chamber bottom surface. Since it is located at, the force of pushing the syringe into the hole acts on the virtual plane, and the force of pushing the syringe downward acts to push the chamber against the ground surface of a desk or the like. Therefore, even if you do not hold this chamber with your other hand, it will not fall down, you can reliably and stably remove the injection needle, and you can safely dispose of the used injection needle. .

容室内に使用済みの注射針が詰まったら、頸部のネジ
（11）にキャップ（図示略）を嵌めたり、その他の方法
で蓋をすれば、安全に処分することができる。If a used needle is clogged in the chamber, it can be safely disposed of by fitting a cap (not shown) to the screw (11) on the neck or by covering the lid with another method.

できる。また、構造も簡素で経済的に製造できる。(Effects of the Invention) According to the present invention, it is possible to easily remove the injection needle from the syringe barrel by holding the syringe in one hand without the need to hold the chamber by hand as described above. Since the needle can be stored in the chamber and discarded, there is no risk of infection with pathogenic bacteria and it can be efficiently treated, so it is convenient when handling a large number of patients and a large amount of It can be widely used for blood sampling, drip infusion, etc. using an injection needle. In addition, the structure is simple and can be manufactured economically.
