Handheld liquid quantitative distribution device

Abstract

The invention relates to a handheld liquid quantitative distribution device which comprises a handheld peristaltic pump and a container for distributed liquid, the handheld peristaltic pump comprises a manual driving part, a pump head and a distribution pipe, one end of the distribution pipe is connected with the container, and the other end of the distribution pipe penetrates through the pump head; the pump head comprises a rotating part used for extruding the distribution pipe, and the manual driving part is in driving connection with the rotating part and used for driving the rotating part to rotate so as to quantitatively send out liquid in the container through the distribution pipe.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a handheld liquid quantitative distribution device. Background technique [0002] Varicose veins of the lower extremities are common diseases in vascular surgery, which refer to vascular diseases characterized by dilated lesions due to venous return obstruction caused by the insufficiency of the superficial venous valves of the lower extremities. A healthy venous valve will help the normal return of venous blood. However, once the venous valve expands or its function becomes weak, the blood will flow back to the lower extremity veins, increasing the pressure in the lower extremity veins, which will become tortuous, dilated, and form varicose veins. [0003] The main risk factors associated with varicose veins are prolonged standing, prolonged sitting, increasing age, obesity, pregnancy, etc., and are also affected by genetic inheritance. According to statistics, the inci...
