Arid drainage valve and burden pressure drainage device

Abstract

The invention discloses an arid drainage valve and a burden pressure drainage device. The arid drainage valve comprises a valve body, an air inlet and an air outlet communicated with a valve chamber are arranged on the valve body; sensing diaphragms transformable by air force are arranged in the valve chamber; the medial surface close to the air inlet side in the valve chamber is a smooth structure wide on the top and narrow at the bottom. The burden pressure drainage device comprises indigestion cavities connected with pleural cavities of the patients through the drainage pipe; the arid drainage valve is arranged on the burden pressure drainage device in the shell of the indigestion cavities; the air inlet of the arid drainage valve is communicated with the internal of the indigestion cavity, and an air exhaust port is arranged oriented outside the shell. By the device, the remnant gas in the pleural cavities the patients is able to be released comfortably, the pain at the stress release is not arisen, at the same time a water envelope structure of the old burden pressure drainage device is removed, and the volume of the burden pressure drainage device is conduced to decrease. Fast use is manageable without water origin. The arid drainage valve and the burden pressure drainage device are suitable for first aid ambulances at combat readiness and emergencies, and have significances in militaries and disaster salvages.

Description

technical field [0001] The invention relates to a one-way valve and the application of the one-way valve in the field of medical equipment, in particular to a dry drainage valve and a negative pressure drainage device. Background technique [0002] The pleural cavity of the human body is a closed cavity, which is in a negative pressure state under healthy conditions, so that the organs in the thoracic cavity can maintain normal functions. Any trauma, car accident, compound chest injury, pneumothorax surgery and other reasons that cause pleural cavity damage and rupture will cause gas or liquid to enter the pleural cavity, causing the original negative pressure to become positive pressure, resulting in atelectasis, cardiac mediastinal pressure, etc. Displacement can cause cardiopulmonary failure. During treatment, it is necessary to drain the gas or liquid entering the pleural cavity through a drainage device to restore the original negative pressure state of the pleural cav...
