Description

A fixture for syringe drainage

technical field

The invention relates to the technical field of medical devices, in particular to a fixing device for syringe drainage.

Background technique

Syringe negative pressure drainage uses the principle of negative pressure suction to generate a pressure lower than atmospheric pressure at the wound surface to suck out the liquid under the wound surface. The application of disposable syringe negative pressure drainage after plastic surgery can not only maintain effective drainage, but also facilitate the observation of the nature of the drainage fluid and the accurate recording of the drainage volume, thereby reducing the occurrence of complications such as flap necrosis and infection.

Orthopedic patients usually leave a disposable syringe for continuous negative pressure drainage after surgery. In clinical practice, a needle is often set between the bottom of the syringe and the piston rod to support the piston rod to fix the piston, thereby ensuring negative pressure in the syringe. However, in the long-term fixation process, due to the patient's own activities or external reasons, the needle is easy to fall off, resulting in the movement of the piston and the inability to maintain a negative pressure in the syringe. And because the length of the needle cannot be adjusted, such syringes cannot meet the requirements of different degrees of negative pressure suction. In addition, paper breathable adhesive tape is used to fix the syringe on the patient in clinical practice. However, due to the long-term sticking and the patient turning over or getting out of bed, the tape is not sticky, and there is a danger of the tube falling off. Furthermore, in the process of negative pressure drainage, the syringe needs to be removed at regular intervals to discharge the accumulated fluid in it. After removal, the syringe needs to be fixed on the patient with adhesive tape again, which is not only troublesome to operate, but also reduces the burden of medical staff. work efficiency.
