Description

Drainage tube stopcock assembly

technical field

The utility model relates to the technical field of medical devices, and more precisely relates to a drainage tube cock valve assembly.

Background technique

In the clinical treatment and nursing of thoracic surgery, the drainage tube is widely used. One end of the drainage tube is inserted into the chest cavity of the patient, and the other end is connected to a drainage bottle or drainage bag lower than the position, so as to discharge gas or collect fluid in the chest cavity. In the process of using the drainage tube, it is necessary to ensure the airtightness of the chest drainage. Since the chest cavity is under negative pressure, in order to prevent the reflux of air accumulation and fluid, causing artificial pneumothorax or chest infection, it is necessary to keep the drainage bottle or drainage bag lower than the chest drainage. The mouth plane is at least 60cm, and the patient cannot move freely. When the patient must get out of bed, the way of clamping the drainage tube with double clamp of blood vessel clamp is usually adopted now. There are some obvious defects in the method of clamping the drainage tube with vascular clamp. First, the material of the vascular clamp is heavy and the volume is large. It is easy to cause discomfort to the patient when clamped on the drainage tube, and it will drag the drainage tube, which increases the The risk of drainage tube slipping, the patient cannot effectively prevent pneumothorax or infection caused by gas and fluid reflux when getting out of bed and going out for inspection. In the daily nursing process, due to factors such as lack of patient knowledge, inadequate education by medical staff, accidents and other factors, the use of existing vascular clamps to clamp the drainage tube has major defects in terms of safety and convenience of operation.
