Description

Safety handling device for medical devices equipped with needles

The present invention relates to a safety processing device for medical devices equipped with a needle, and more particularly, to a safety processing device for safely disposing of various types of medical devices equipped with needles without being stabbed after being used.

Syringe, one of the most commonly used medical devices, consists of a needle formed at the end of a needle penetrating the skin, and has various shapes depending on the use. It is widely used for various purposes such as supplying blood or collecting blood.

However, since a syringe once used for a patient can cause disease transmission by various infectious bacteria or viruses, medical institutions such as hospitals strictly prohibit the reuse of syringes to prevent secondary infection. The disposal of waste is also collected separately and disposed of safely.

As described above, the syringe used in the medical institution is not disposed of as it is, but is separated and discarded after separating the needle and body of the syringe.

In this case, since the operator removes the needle directly by hand in the process of separating the syringe, there is a safety problem of being frequently exposed to blood or contaminated medicine or cut accidents such as being pierced by the needle wire at the tip of the needle.

In order to prevent safety accidents such as puncture or secondary infection by the used syringe, some foreign hospitals are introducing a method of immediate disposal in the hospital using a device that melts the used syringe at high temperature. However, domestic hospitals are sticking to the existing infectious waste treatment method, which collects and separates used syringes without major changes.

In order to prevent various problems caused by the used waste syringe, various methods for safely removing the needle of the syringe have been introduced. 1), as a form of removing the needle of one syringe at a time, the efficiency of the needle removal operation was low, and there was a disadvantage that the operator had to separate and discharge the body from which the needle was removed as well as the injection of the syringe.

Republic of Korea Patent Publication No. 1995-0002795 (published date: February 16, 1995)

It is an object of the present invention to universally dispose of various syringes manufactured in various shapes according to the use with a needle formed at the end of the needle line as a basic configuration through one device, An object of the present invention is to provide a safety processing device for medical instruments equipped with needles that can safely cut needles to promote safety of workers.
