Disposable self-destructing safety anesthesia syringe

Abstract

The present invention is one disposable self-destructing safety syringe with built-in medicine bottle and incapable of being reused. The safety syringe includes one outer sleeve, one hand guard with one end for the outer sleeve to be fixed in, one medicine bottle located inside the outer sleeve, and one fixing seat inside the outer sleeve capable of sliding inside the outer sleeve and with one end for the needle to be set in and the other end for the head of the medicine bottle to be clamped. The inside cavity of the outer sleeve has two lobes separately in its two end, one for limiting the fixing seat to avoid slipping out and the other for matching the fixing seat. The fixing seat has outer lobe set between the hand guard and the outer sleeve; and the medicine bottle has back plug with inserted push rod for pulling out the medicine bottle. The present invention can avoid reuse to prevent cross infection.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable self-destruct safety anesthesia needle syringe with a built-in medicine bottle and ensuring that the syringe cannot be reused after injection. Background technique [0002] Among the traditional syringes, one is a glass syringe that is repeatedly sterilized, and the other is a plastic syringe that is disposable and discarded. When using these two types of syringes, the needle needs to be inserted into the medicine bottle containing the liquid medicine first. In the process, the patient is injected after inhaling the liquid medicine. The syringe and the medicine bottle are set separately, and the work efficiency is low and the operation is cumbersome during injection. In order to overcome the above-mentioned defects, various syringes combining syringes and medicine bottles have also appeared at present, such as the utility model patent of patent No...

Problems solved by technology

[0002] Among the traditional syringes, one is a glass syringe that is repeatedly sterilized, and the other is a plastic syringe that is disposable and discarded. When using these two types of syringes, the needle needs to be inserted into the medicine bottle containing the liquid medicine first. In the process, inject the patient after inhaling the liquid medicine, the syringe and the medicine bottle are set separately, the work efficiency is low and the operation is cumbersome during injection

In order to overcome the above-mentioned defects, various syringes combining syringes and medicine bottles have also appeared at present, such as the utility model patent of patent No. CN98249286.3, which discloses a dental anesthetic syringe used in dentistry. Bottles and needles are disposable, but syringes are reusable, so this kind of syringe cannot ensure the self-destructability of the syringe itself after the injection is completed, fundamentally prevents the phenomenon of repeated use, and cannot guarantee people's health

At the same time, after the existing syringes are used up, the collectors of the syringes will accidentally be stabbed by the exposed syringe needles when collecting the discarded syringes, which is very poor in safety.
