A medical needle safety protection device

Abstract

The invention discloses a medical needle safety protection device which comprises an outer housing and an inner housing. The inner housing is in eccentric sleeved connection with the outer housing, the outer housing can rotate with respect to the inner housing, a first opening for a medical needle tube to pass through is formed in the head end of the inner housing, the inner housing can axially move with respect to the medical needle tube, a second opening and a third opening which are used for a medical needle head to pass through are respectively formed in the tail end of the inner housing and the tail end of the outer housing, the second opening is located in the central position of the tail end of the inner housing, and the third opening is located in the position, biasing to the center, of the outer housing. The medical needle safety protection device can bend a needle point in a pressing mode so as to destroy the medical needle head. In addition, due to the fact that the tail ends of the housings and the protective needle point of a clamp are also not exposed outside, and personal injury is avoided.

Description

technical field [0001] The invention relates to a medical needle safety protection device, which belongs to the technical field of medical instruments. Background technique [0002] Medical needles, such as hypodermic needles, biopsy needles, intravenous introducers, trocars, guide wires, thoracentesis needles, etc., after use, these will become dangerous goods after they are contaminated with drugs or pathogens on patients, and due to accidental use by these There are too many cases to be punctured by instruments with needles. In order to avoid the health risk of being punctured by such contaminated thorns or infected thereby, there are some protective devices in the prior art, but some of the existing protective devices protect If it is not in place, it is often possible to suffer secondary injuries. [0003] Furthermore, the existing various medical needles are disposable, and after use, they are simply put on the needle cap and discarded immediately. Because the needle ...

[0002] Medical needles, such as hypodermic needles, biopsy needles, intravenous introducers, trocars, guide wires, thoracentesis needles, etc., after use, these will become dangerous goods after they are contaminated with drugs or pathogens on patients, and due to accidental use by these There are too many cases to be punctured by instruments with needles. In order to avoid the health risk of being punctured by such contaminated thorns or infected thereby, there are some protective devices in the prior art, but some of the existing protective devices protect If it is not in place, it is often possible to suffer secondary injuries

[0003] Furthermore, the existing various medical needles are disposable, and after use, they are simply put on the needle cap and discarded immediately. Because the needle cap is not firm, it will also cause harm to the staff who handle these medical wastes, and even some Lawbreakers recycle these discarded medical needles, which poses a greater safety hazard. The existing technology has not yet found a more thorough protection device for this situation, which will completely damage the used needles, which can not only avoid stab wounds but also Prevent recycling by those who care
