Novel multifunctional pleuroperitoneal cavity drainage tube

Abstract

The invention relates to a novel multifunctional pleuroperitoneal cavity drainage tube which comprises a double-cavity drainage tube formed by a main drainage tube and an auxiliary drainage tube. Thecross sections of the main drainage tube and the auxiliary drainage tube are semicircular; the main drainage tube and the auxiliary drainage tube are attached together back to back to form the double-cavity drainage tube with a round cross section, the tail ends of the main drainage tube and the auxiliary drainage tube are separated and are both provided with fasteners, and a flow rate control valve is arranged at the tail end of the main drainage tube. The double-cavity drainage tube is provided with a conical air bag. By utilizing the double-cavity drainage tube, the situation can be avoidedthat a single-cavity drainage tube needs to be re-punctured and replaced due to blockage of the single-cavity drainage tube, pain of a patient is relieved, and workload of medical staff is relieved;continuous drainage is executed through the main drainage tube, and continuous flushing or medicine injection is executed through the auxiliary drainage tube; after the conical air bag is expanded, the conical air bag can be tightly attached to the skin, exudate at a wound can also be prevented from seeping outward; the flow rate control valve can control the drainage speed. The novel multifunctional pleuroperitoneal cavity drainage tube is simple in structure, low in cost, convenient to use, good in fixation, controllable in flow rate, convenient for washing and medicine injection, small in trauma to patients and free of repeated drainage bag replacement.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a novel multifunctional thoracoabdominal cavity drainage tube. Background technique

[0002] In clinical work, thoracic surgery, respiratory medicine and oncology often have patients with pleural effusion, peritoneal effusion or pneumothorax and need to place chest or peritoneal drainage tubes. The purpose of the drainage tube is to drain the effusion, blood or air accumulation, promote lung recruitment and relieve compression symptoms. The traditional drainage tube has no fixing device, and the adhesive tape is easy to fall off due to skin oil, dandruff or unintentional dragging when it is fixed on the skin. Some of them need to suture the drainage tube to the skin at the puncture point, which brings pain, movement disorder and wound at the puncture point to the patient. Delayed healing, etc. Traditional drainage tubes are mostly single-lumen flexible tubes with thin lumens, and...
