Abstract

The present invention relates to an automatic needle separating and collecting apparatus enabling a reliable syringe removal and, more particularly, to a novel technology for a complete removal of a syringe and thus enabling accurate separation and collection when a needle is removed from the used syringe. An existing needle separating and collecting apparatus often has a needle hub of a syringe jammed in a syringe support hole of a pick-out bucket and unable to fall out while the pick-out bucket rotates and pulls the syringe out of a needle, thereby resulting in incomplete separation and collection of the syringe. The present invention provides a solution to the problem by enabling a push pin to push a needle hub of a syringe and the syringe to be completely removed from the draw bucket when a draw bucket rotates and pulls out the syringe.

Description

Needle Separator to ensure syringe is removed

The present invention relates to a new concept of technology that reliably removes a syringe when separating a needle from a used syringe to accurately carry out a separate collection.

In general, the use of syringes is strictly prohibited to reuse as classified as infectious waste in order to prevent the correct introduction of designated drugs and secondary infection of pathogens.

The general structure of such a syringe includes a syringe body configured in the form of a cylinder for the storage of the chemical liquid, and a chemical liquid through a needle formed in front of the syringe body by sucking the chemical liquid using a piston inserted into the syringe body and then pushing the piston again. It is made of a structure to discharge.

In addition, the needle is detachable from the syringe so as to be prevented from being punctured by doctors, nurses or waste handlers, and is disposed of separately.

When disposing of the needle, the needle attached to the main body of the syringe is formed of a metal needle and protrudes out of the bag and the container at the time of collection, and the worker is injured in the process of carrying and transporting it manually, exposing the risk of secondary infection. There was a problem.

In order to solve this problem, the needle is separated and collected from the main body of the syringe, but since it is still dependent on the manual operation of the operator, there is a risk of infection and the syringe body and the needle are firmly fixed during the separation operation. The problem is not easy to work with.

Accordingly, a technique for separating the needle from the syringe without infection at all has been proposed. As a representative prior art, "Patent Registration No. 1141775, Name / Automatic needle collection of syringe" has been proposed.

The prior art provides an effect of automatically removing the syringe from the needle while rotating the pick-out bucket by pressing and holding the needle to the fixed presser while the moving presser is automatically sliding when the syringe is put into the pick-out bucket.

However, in the prior art, the needle hub of the syringe is frequently caught in the syringe support hole of the pick-out bucket so that it is not detached to the outside while the pick-out bucket is rotated and the syringe is removed from the needle. A problem that cannot be achieved is caused.

The present invention seeks a technique that allows the syringe to be completely removed from the draw bucket while the pin is pushing the needle hub of the syringe when the draw bucket is rotated and the syringe is pulled out.

According to the present invention, in conjunction with the rotation operation of the draw bucket for extracting the syringe, the mil pin protruding into the inside of the draw bucket automatically pushes the needle hub of the syringe, so that the syringe stuck inside the draw bucket is completely drawn from the draw bucket. It can remove and smoothly carry out the separate collection work, and can prevent product malfunction and improve the quality.
