Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a portable oxygen supply and sputum suction device. Background Art

[0002] Suctioning is a common operation method in clinical practice. It refers to sucking out respiratory secretions through the mouth, nose or artificial airway, so as to keep the respiratory tract open and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. It is mainly suitable for people who are unable to cough and produce sputum; those who need suction to help clear the respiratory tract after endotracheal intubation or tracheotomy; those who are drowning or have massive hemoptysis; those who are critically ill, unconscious, elderly, under general anesthesia, after major surgery, and have chest trauma; patients whose respiratory tracts are blocked by vomitus and secretions and who have various breathing difficulties and cannot cough effectively for various reasons.

[0003] Effective respiratory management can effectively reduce complications and improve symptoms of hypoxia. At present, the suction devices used in hospitals include central negative pressure suction systems and electric suction devices. Among them, the central negative pressure suction system can only be used in hospital wards, which is very inconvenient for patients who need to be transferred or go out. The electric suction device is more flexible in use than the central negative pressure suction system, but the structure of the electric suction device is relatively simple and the function is relatively single, which has certain limitations for patients who need long-term suction. In addition, most of the current open suction tubes are disposable, which greatly increases the economic burden of patients who need repeated suction. In order to reduce the hypoxia symptoms of patients during suction, oxygen suction tubes have also begun to be used in clinical practice, but the current oxygen suction tube is a double-lumen tube and there are no small holes in the wall of the oxygen supply tube, resulting in limited oxygen absorption.
