Special waste liquid extraction device for emergency treatment of severe patients in internal medicine department

Abstract

The invention discloses a special waste liquid extraction device for emergency treatment of severe patients in an internal medicine department. An adjusting mechanism comprises a first micro motor welded to one side face of a middle plate, two first screw rods symmetrically arranged on the inner side of the middle plate and rotationally connected with the middle plate, inner sliding seats arranged on the two first screw rods in a threaded and sleeving mode, and a driving assembly arranged in an inner cavity of a machine part. A needle inserting mechanism comprises a liquid extraction hose connected to the side face, back to the first micro motor, of a waste liquid tank and communicating with an inner cavity of the waste liquid tank, a needle arranged at the end, away from the waste liquid tank, of the liquid extraction hose, an extension plate welded to the side face, back to the first micro motor, of the inner sliding seats and a self-adjusting assembly. A power-on control mechanism comprises an operator fixedly bonded to the side face, facing the needle head, of the waste liquid tank, a manual control assembly arranged on the operator and two communication assemblies arranged in an inner cavity of the operator. According to the special waste liquid extraction device for emergency treatment of the severe patients in the internal medicine department, the trouble of adjusting the position of the needle head by personnel and manually inserting the needle is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a special waste liquid extraction device for first aid of critically ill patients in an internal medicine department. Background technique [0002] Internal medicine is a specialty of clinical medicine and occupies an extremely important position in clinical medicine. It is not only the basis of various clinical medicine subjects, but also closely related to them. The content of internal medicine includes the definition of disease, etiology, pathogenic mechanism, epidemiology, natural history, symptoms, signs, laboratory diagnosis, imaging examination, differential diagnosis, diagnosis, treatment and prognosis. The knowledge of internal medicine comes from medical practice. In the process of treating diseases and saving lives, medical scientists have continuously accumulated experience, discarded the false and kept the true, discarded the rough and picked the ...

Problems solved by technology

However, most of the devices currently used for pumping waste liquid only connect a waste liquid tank, an infusion tube and a needle, requiring medical staff to manually find the correct position to prick the needle, and manually pinch the needle or infusion tube during the process of pumping waste liquid (so that the needle does not fall into place) Shaking), but in actual operation, it is more troublesome to prick the needle, and if the medical staff accidentally shakes their hands during the pumping process, there may be problems such as not being able to pump waste liquid
