Improved drainage device special for thoracic surgery department

Abstract

The invention relates to the field of medical instruments, and particularly to an improved drainage device special for the thoracic surgery department. The improved drainage device special for the thoracic surgery department comprises a hydrops bottle, wherein the cover body is in threaded connection with the upper end of the hydrops bottle, and the negative pressure air bag assembly is communicated with the effusion bottle through a negative pressure catheter. The right end of the negative pressure guide pipe penetrates through the cover body and extends into the upper part of the effusion bottle; a hydrops conduit is arranged at the left part of the cover body; the left end of the effusion guide pipe penetrates through the cover body and extends into the upper part of the effusion bottle; a buffer ball is connected to the right end of the hydrops catheter, a liquid outlet pipe in interference fit with the right end of the hydrops catheter is arranged on the lower portion of the buffer ball, a liquid inlet pipe in interference fit with the left end of the drainage pipe is arranged on the right portion of the buffer ball, and a dredging assembly is connected to the left portion ofthe buffer ball through a threaded pipe and comprises a piston pipe; the drainage device is simple in structure, low in cost, convenient to use, convenient to disassemble and assemble and convenient to clean and disinfect, meanwhile, the dredging frame is driven to penetrate into the drainage tube by continuously pressing the small air bag, the drainage tube is dredged, and therefore the drainageeffect of hydrops is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an improved special drainage device for thoracic surgery. Background technique [0002] Thoracic surgery is a medical specialty that specializes in the study of thoracic organs, mainly referring to the diagnosis and treatment of esophagus, lung, and mediastinal lesions. The field of breast surgery is also included in this specialty, of which pulmonary surgery and esophageal surgery are the main ones. In the process of thoracic surgery diagnosis and treatment or postoperative care, it is often encountered that the patient has too much fluid in the body caused by various reasons, and it is necessary to perform negative pressure drainage on the patient. [0003] At present, the negative pressure drainage device mainly includes a drainage tube, an effusion bottle connected with the drainage tube, and a negative pressure device. The negative pressure is generated by the negative pre...
