る。Function To remove a used syringe needle from the tip of the outer barrel of a syringe barrel using the syringe needle disposal container of this invention,
First, turn the syringe barrel with the needle attached sideways,
Place the proximal end of the syringe barrel into the indentation and move it inside the container. At this time, first, the minimum thickness portions of the thickened portions present on both sides of the indented portion enter between the proximal end of the base of the injection needle and the end surface of the syringe barrel. and,
As the syringe barrel is moved toward the inlet, one side of the thick wall portion touches one of the end face of the syringe barrel and the proximal end of the needle base, and the other face touches either the end face of the syringe barrel and the proximal end of the needle base. Each of the proximal ends abuts on the other. If you move the syringe further,
The thickened portion gradually becomes thicker, and a force is applied to the needle base to pull it inward into the container, and this force causes the needle base to come off the barrel tip. And the needle that came off,
It is housed in a container through a long hole for inserting a syringe needle.
In this way, the syringe needle is removed from the syringe barrel. When the container is full of used needles, discard the entire container. In addition, the elongated hole for inserting the syringe needle is located on the peripheral wall of the container,
When formed in the surrounding wall provided around the elongated injection needle insertion hole, the injection needle is prevented from falling by the outwardly protruding injection needle fall prevention wall.
