Improved thoracic cavity closed drainage device

Abstract

The invention relates to the field of medical instruments, in particular to an improved thoracic cavity closed drainage device which comprises a main drainage device, an auxiliary drainage device anda connecting assembly connected to the main drainage device and the auxiliary drainage device through threads, and the main drainage device is divided into a drainage chamber and a saline chamber. According to the device, through the connecting assembly arranged in the middle, the main drainage device is connected with the auxiliary drainage device; after drainage liquid of the main drainage device is drained into the auxiliary drainage device through the connecting assembly, only the auxiliary drainage device needs to be detached for measurement and toppling over, meanwhile, the leakproofnessof a drainage chamber of the main drainage device is guaranteed under the action of the connecting assembly, and the problem that an original drainage device is exposed and prone to pollution when detached is solved. The detachable filter cotton is additionally arranged at the saline water injection port of the saline water chamber, so that the safety is further improved, the clinical use is facilitated, and the medical requirements are met.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an improved closed chest drainage device. Background technique [0002] At present, in the medical field, when there is accumulation of air and fluid in the pleural cavity of a patient, it may lead to lung collapse, decreased respiratory function, and even life-threatening, and closed pleural drainage is usually performed on such patients. The closed chest drainage device used in the hospital is replaced once a week, and the drainage fluid is poured out every day and the amount of drainage fluid is recorded. When pouring, two blood vessel forceps are required to clamp the drainage tube, and the drainage cover is opened to expose it to the air. The drainage device after dumping There are blood clots, mucus, etc. on the inner wall. After pouring, you need to cover the lid and inject 500ml of sterile water for injection. It is inconvenient to clean. After opening the device, it is eas...

Problems solved by technology

The closed chest drainage device used in the hospital is replaced once a week, and the drainage fluid is poured out every day and the amount of drainage fluid is recorded. When pouring, two blood vessel forceps are required to clamp the drainage tube, and the drainage cover is opened to expose it to the air. The drainage device after dumping There are blood clots, mucus, etc. on the inner wall. After dumping, you need to cover the lid and inject 500ml of sterile water for injection. It is inconvenient to clean. After opening the device, it is easy to cause artificial secondary pollution and cause potential retrograde chest infection risk to the patient.
