Abstract

The invention discloses an auxiliary device for artificial pneumatic control coughs. The auxiliary device comprises a pneumatic control switch valve and an air bag, wherein the pneumatic control switch valve is a normally open valve body; the pneumatic control switch valve is arranged along a ventilation pipe and is arranged at a position close to the mouth of a patient; and the air bag is arranged outside the body and is connected with the pneumatic control switch valve through a pipeline. According to the device, the pneumatic control switch valve is combined with the simple air bag, the patient can hold breath through the pneumatic control switch valve, the breath holding time is autonomously controlled through the air bag held in the hand, and when the patient feels that coughs are needed, the patient can inhale deeply by himself and hold the air bag before expiration, so that the pneumatic control switch valve is closed and then loosened, and a higher gas outlet flow is formed; and therefore, the purposes of removing sputum in small airways, promoting the control of pulmonary infection and the rehabilitation of the patient and reducing the risk of nosocomial infection are achieved, and the device is simple in overall structure, low in cost and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more particularly to an artificial air-controlled cough assisting device and an assisting method. Background technique [0002] At present, endotracheal intubation technology has been widely used in the rescue and nursing of critically ill patients. The glottis of patients using endotracheal intubation is restricted by intubation. Even if they are conscious, they cannot close the glottis voluntarily, so they cannot produce spontaneous coughing. , resulting in sputum accumulation in the patient's respiratory tract, which may cause mucus plugs to obstruct the respiratory tract, form pulmonary lobules or alveolar atelectasis, cause or aggravate inflammation, reduce oxygenation, and even cause breathing difficulties and suffocation. Therefore, it is particularly important to expel sputum from the respiratory tract, especially deep sputum, in a timely manner. [0003] The existing technol...
