Telescopic floating type medical care negative pressure drainage device

Abstract

The invention discloses a telescopic floating type medical care negative pressure drainage device which comprises a telescopic mechanism. The telescopic mechanism is additionally arranged at the bottom of the liquid storage tank, the lower screw hole plate and the floating tank are driven to float up and down by rotating the driving screw rod, and meanwhile the telescopic ring body is driven to stretch out and draw back, so that the volume of the bottom of the liquid storage tank is adjusted, volume adjustment is achieved, and use is more flexible.

Description

technical field [0001] The invention relates to a telescopic floating medical nursing negative pressure drainage device. Background technique [0002] Surgical drainage refers to the extraction of fluids in body cavities, joint cavities, organs or tissues, including blood, pus, inflammatory discharge, bile, secretions or cystic fluid, etc., so as to prevent or treat the accumulation of fluid in the body. The damage caused; the existing negative pressure drainage device generally pushes the piston plate through the push rod to exhaust and inhale, forming the negative pressure suction structure of the drainage tube, and in addition, the drainage is realized through the extrusion and expansion of the air bag The negative pressure of the tube is formed, but whether it is through the structure of pushing the piston plate or the extrusion and expansion of the air bag, sometimes the user may mistakenly push the protruding piston push rod or squeeze the expanded state. Airbag, when...

[0002] Surgical drainage refers to the extraction of fluids in body cavities, joint cavities, organs or tissues, including blood, pus, inflammatory discharge, bile, secretions or cystic fluid, etc., so as to prevent or treat the accumulation of fluid in the body. The damage caused; the existing negative pressure drainage device generally pushes the piston plate through the push rod to exhaust and inhale, forming the negative pressure suction structure of the drainage tube, and in addition, the drainage is realized through the extrusion and expansion of the air bag The negative pressure of the tube is formed, but whether it is through the structure of pushing the piston plate or the extrusion and expansion of the air bag, sometimes the user may mistakenly push the protruding piston push rod or squeeze the expanded state. Airbag, when the shut-off valve on the drainage tube is not closed, the airflow will be discharged from the drainage tube and the drainage liquid will be splashed, which will make the reliability of the device worse. In addition, the way of pushing the piston or squeezing the airbag is generally through the spring Rebound, so it is not easy to control the degree of negative pressure drainage in real time, which causes the problem of excessive negative pressure or too small negative pressure during drainage. In addition, the existing drainage device does not have the filtering function, and the existing drainage device does not have the function of filtering. No capacity adjustment function
