Sputum aspirator

Abstract

The invention is a medical instrument, especially a sputum aspirator. The sputum aspirator comprises a tube body and a sputum aspirating channel, wherein the tube body is provided with an observing cavity and an oxygen injecting channel; the port of the observing cavity at the sputum aspirating end of the tube body is transparent and closed; the observing cavity is provided with a minitype camera or an optical fiber; and the other end of the minitype camera or the optical fiber is connected with the signal output end of a visual device. By adopting the above tri-cavity structure, the invention has the advantages of simplifying sputum aspirating process, improving working efficiency of nursing personnel, alleviating pain of patients and lowering medical cost for patients.

Description

technical field [0001] The invention relates to a clinical medical device, in particular to a sputum suction device which integrates sputum suction and oxygen injection and has high safety. Background technique [0002] Clinically, many patients cannot expectorate sputum on their own, and need artificial assisted sputum suction to keep the airway unobstructed and facilitate lung ventilation. Therefore sucking sputum with a sputum suction device is a kind of medical device commonly used in clinical medicine. [0003] In the prior art, the sputum suction and oxygen inhalation catheters are single-lumen. When the patient needs sputum suction and oxygen inhalation, two catheters are inserted. Repeated catheter insertion will directly cause damage to the tracheal mucosa, including congestion and edema, epithelial exfoliation, cilia Loss and granuloma formation, and increase the chance of bleeding and infection in patients, and often cause hypoxemia in patients due to irritating ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the sputum suction and oxygen inhalation catheters are single-lumen. When the patient needs sputum suction and oxygen inhalation, two catheters are inserted. Repeated catheter insertion will directly cause damage to the tracheal mucosa, including congestion and edema, epithelial exfoliation, cilia Loss and granuloma formation, and increase the chance of bleeding and infection in patients, and often cause hypoxemia in patients due to irritating cough or insufficient oxygen supply

And when in use, the medical staff judges where to insert according to experience, and the safety is low

[0004] However, in the prior art, if the suction tube is inserted too shallow, the sputum in the upper part of the airway can only be sucked out, and all the sputum cannot be completely sucked out. The sputum in the deep part of the trachea is likely to form a sputum scab to block the airway or cause complications of pulmonary infection.

Sputum suction can also be performed under the guidance of laryngoscope or bronchofiberscope, but the former can only observe part of the airway, which is not helpful for deep suction, while the latter needs to be performed on the basis of local anesthesia, which is cumbersome to operate. The cost is expensive and requires high technical level of medical staff

[0005] To sum up, the sputum suction device in the prior art has a single function, increases the pain and cost of the patient during use, requires relatively high operating skills for the operator, and has low safety
