Description

Drainage pipe squeezing device

The present invention relates to a drain pipe squeezing device capable of automatically squeezing the drain pipe.

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

The drainage tube is used to remove the drainage from the body after surgery, and has a tube shape made of a flexible material. However, if there are hematomas, necrosis, clots, etc. in the drainage from the surgical site to the drainage tube, the viscosity of the drainage increases. As a result, as the drain is stored in the drain tube, the drain tube is clogged. Therefore, in the medical field, medical personnel frequently squeezing or milking the drainage pipe to pierce it.

Here, the squeezing of the drain pipe means squeezing the drained material stored in the drain pipe by pressing the drain pipe in the longitudinal direction. In addition, the milking of the drain tube means to soften the drained material stored in the drain tube by pressing the drain tube.

Conventionally, squeezing or milking of the drain pipe was performed manually by medical personnel.

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