Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical and nursing technology and relates to a closed thoracic drainage tube clamp. Background Technology
[0002] Thoracoscopic lobectomy is the most important method for treating pulmonary nodules. After thoracoscopic lobectomy, to help expel gas or collect pleural fluid, a closed thoracic drainage tube is often placed postoperatively. Maintaining the drainage tube's connection to the outside environment plays a crucial role in improving surgical outcomes and reducing postoperative complications. However, during closed thoracic drainage, when the patient needs to be transported for examinations or to change the drainage bottle, medical staff must clamp the drainage tube with hemostats to interrupt fluid flow before proceeding with nursing procedures. However, hemostats are large and heavy, and during transport, their weight can easily cause traction or insecure clamping, leading to dislodgement. This can result in drainage fluid leakage or outside air entering the patient's pleural cavity, endangering their life.
[0003] Patent CN207591103U discloses a portable closed thoracic drainage tube clamp, comprising: a U-shaped body having an upper body, a lower body, a first connector, and a second connector; the first connector is fixedly connected to one end of the upper body and one end of the lower body; the lower end of the second connector is connected to the other end of the lower body, and the upper end is closably fastened to the other end of the upper body; a support part having an upper support body and a lower support body; and an engagement part having an upper engagement body and a lower engagement body; the upper engagement body is fixed to the fixed end of the upper support body, and the lower engagement body is mounted on the fixed end of the lower support body. Both the first and second connectors have through holes. When the upper end of the second connector is fastened to the other end of the upper body, the upper and lower engagement bodies are misaligned, with the upper engagement body being closer to the lower body than the lower engagement body. However, this patent does not allow adjustment of the clamping degree of the drainage tube.
[0004] Patent CN220344813U discloses a clampable closed thoracic drainage tube clamp, including a first clamp and a second clamp, both of which are slidably connected to a fixing member. One end of the first clamp and the second clamp are engaged, and the first clamp and the second clamp are used to bidirectionally close the drainage tube. However, this patent does not have a suitable clamping position to fix the drainage tube, and only uses an arc-shaped groove to clamp the drainage tube, which makes the drainage tube very easy to slide.
