Description

Squeezing device for drain pipe {SQUEEZING DEVICE FOR DRAINAGE TUBE}

The present invention relates to a drainage pipe squeezing device that can automatically squeeze a drainage pipe.

Body fluid (hereinafter referred to as “drainage”) that accumulates in tissues after surgical operations interferes with wound healing and causes complications. Therefore, to prevent the drainage fluid from accumulating in the tissue after surgery, a drainage tube is inserted into the surgical site after the surgical window is closed to discharge the fluid accumulated inside the surgical window out of the body.

A drainage tube is used to remove fluids that accumulate in the surgical area after surgery out of the body, and has a tube shape made of flexible material. However, if hematoma, necrosis, or blood clots are present in the drainage fluid delivered from the surgical site to the drainage tube, the viscosity of the drainage fluid increases. As a result, as drainage fluid accumulates in the drainage pipe, the drainage pipe becomes clogged. Therefore, in medical settings, medical personnel frequently open drainage pipes by squeezing or milking them.

Here, squeezing the drainage pipe means pressing the drainage pipe in the longitudinal direction to squeeze out the drainage fluid accumulated in the drainage pipe. In addition, milking the drainage pipe means pressing the drainage pipe to soften the drainage fluid accumulated in the drainage pipe.

Previously, squeezing or milking of drainage tubes was done manually by medical personnel.

However, in the medical field, as one medical professional cares for multiple patients, there is a problem that squeezing or milking of the drainage tube is delayed or performed inappropriately.
