Description

A disposable closed sputum suction and collection device

technical field

The invention relates to the field of medical devices, in particular to a disposable closed sputum suction and collection device.

Background technique

With the gradual aggravation of respiratory tract patients, the number of critically ill patients such as endotracheal intubation and mechanical ventilation gradually increases, and sputum suction is often required for patients. At present, the widely used method for removing artificial airway secretions is the closed suction technique, which connects the closed suction tube with the artificial airway, the Y-shaped tube of the ventilator and the negative pressure suction equipment to form a closed system. The sputum operation is performed in a relatively closed space, and there is no need to disconnect the ventilator during the treatment process, which can effectively reduce the occurrence of alveolar collapse caused by sputum suction, and can significantly reduce tissue hypoxia caused by sputum suction; Effectively reduce the occurrence of VAP; at the same time, using a closed sputum suction tube to suck sputum can effectively reduce cross-infection, especially avoid cross-infection of medical staff and other patients, can effectively protect medical staff, improve the safety of nursing work, and reduce the incidence of nosocomial infection. occur.
