Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention relates to a container for discarding an injection needle, an injection cylinder, or the like used for injection, blood collection, drip, or the like.

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 in a container and stored and discarded, both hands must be used to use it, there is a risk of accidentally touching the injection needle to be infected with pathogenic bacteria, and the syringe with the injection needle removed Often processed separately from the needle,
It is dangerous because it often causes dripping of liquid medicine, blood, etc. remaining in the syringe, and it is also unclean and inefficient.

(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 a container portion for accommodating a used injection needle. And a container chamber adjacent to this container for accommodating the used syringe, and a virtual plane including this hole intersects with the bottom surface of the container for accommodating the syringe in an inclined state. By moving the injection needle inserted from the large hole to the small hole side and moving the piston pressing part on the side opposite to the needle tip of the syringe downward,
Push the needle tip downward to squeeze the injection needle, and without having to touch the injection needle, you can easily pull it out with one hand without pressing and fixing the container. By making it possible to dispose of the injection syringe after it has been put into the chamber through the adjacent inlet, it is intended to obtain a safe and efficient treatment without the risk of being infected by pathogenic bacteria. .

Speaking with the examples below, there is a means for withdrawing the injection needle in the container that holds the used injection needle, and this container is usually made of 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.
Adjacent to this container is a container containing a used syringe barrel, and the container is made of the same material as that of the container.

The illustrated one is provided with a neck portion (3) protruding from the front surface (2) of a small box-shaped container (1), and an extraction hole (4) serving as an extraction means is formed at the tip of this neck portion. There is. 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. . Although the shape shown in the drawing is triangular, it may be shaped like a keyhole or any other suitable shape. A large box-shaped chamber (7) projecting forward is located under the container. The container portion is detachably fitted from the container chamber (8), but it can be integrally formed by, for example, preventing the contents stored in the container from being mixed with each other.

The virtual plane (9) in which the extraction hole (4) provided in the container is located is inclined with respect to the bottom surface (10) of the container (7) and intersects with the bottom surface of the container. There is. In this case, the angle (α) formed by the virtual plane with the bottom of the container is about 45.
If it is formed so as to have a number of times or more, it is more preferable in some cases because a compact chamber allows an effective extraction operation.

The inlet for discarding the injection cylinder provided in the chamber is usually preferably provided adjacent to the extraction hole, and in the illustrated case, a cylindrical inlet (1
1) is located below the extraction hole. The container and the chamber may have a tubular shape or any other suitable shape.

When using this, hold the used syringe barrel (12) in one hand and insert the injection needle through the hole with the large extraction hole until the needle base is hidden inside the volume. It is moved to the hole side so that 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 injection barrel downward, the needle base of the injection needle is at the small hole portion of the extracting means. As the needle is twisted, the injection needle loosens from the needle tip (13) of the syringe and falls out and is stored as it is in the container.

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. . When the above-mentioned injection needle is pulled out, the drug solution, blood, etc. remaining in the syringe barrel may flow down, but since the inlet of the chamber is located below this withdrawal hole, this drug solution, blood Etc. are received from the input port, do not scatter around and become dirty, and if this syringe is also input from the input port, it can be disposed of cleanly in the chamber.

When needles and syringes have accumulated in this vessel and chamber, insert the cap (15) into the screw (14) on the neck of the vessel and cap (17) with the screw (16) at the inlet of the chamber. After fitting or closing the lid by another method, the container and chamber are separated and discarded, but if they are integrated, they may be discarded together.

(Effect 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. The needle can be stored in the chamber, and the used syringe from which the injection needle has been removed can be stored in the adjacent chamber and discarded, so there is no risk of infection by pathogenic bacteria, and there is no risk of chemicals, blood, etc. It can be processed efficiently without getting dirty, so it is convenient when dealing with a large number of patients or a large amount of it.
It can be widely used for those using an injection needle such as blood collection and infusion. In addition, the structure is simple and can be manufactured economically.
