Multifunctional safety vacuum blood drawing ergonomic syringe

Abstract

The multifunctional safe phlebotomizing syringe includes one hollow needle tube with one eccentric opening in the top and one guide slot in the side, one inner sleeve inside the needle tube with one pressing board and one needle seat, and one double-L shaped needle fixed to the inner sleeve with lower tip in the axis of the needle tube. The present invention may be combined with one vacuum bloodsampling cup, and by means of the said structure the needle may be fixed inside the needle tube or detached conveniently to protect medical staff and protect environment.

Description

【Technical field】 [0001] The invention relates to a blood-drawing syringe, in particular to a multifunctional and safe vacuum blood-drawing syringe conforming to ergonomics. [Background of the invention] [0002] For general medical institutions, it is common and frequent work to conduct blood analysis tests on patients, to understand the bacteria or diseases infected by patients through blood analysis, and to detect whether the physiological functions of the human body are normal. After drawing blood from the patient, the medical staff often need to cover the needle back to the needle head. This action often causes the medical staff to accidentally stab themselves, increasing the possibility of the medical staff being infected with fatal diseases. Therefore, the choice of blood drawing tools is particularly important.

Problems solved by technology

[0002] For general medical institutions, it is common and frequent work to conduct blood analysis tests on patients, to understand the bacteria or diseases infected by patients through blood analysis, and to detect whether the physiological functions of the human body are normal. After drawing blood from the patient, the medical staff often need to cover the needle back to the needle head. This action often causes the medical staff to accidentally stab themselves, increasing the possibility of the medical staff being infected with fatal diseases. Therefore, the choice of blood drawing tools is particularly important.

[0003] In addition, since the syringe and the needle are made of different materials, on the one hand, because the needle is a sharp object, it must be recycled separately from the syringe in the recycling of medical waste. Traditionally, the medical staff puts the needle cover back on. It is necessary to twist the needle by hand and place the needle in the recycling bin. This process also puts medical personnel in danger, and it is easy to cause disease infection due to the problem of handling the needle
