A system and method for automatic cleaning of respiratory tract sputum

Abstract

The invention provides a system and method for automatic cleaning of respiratory sputum, including a sputum suction device and a monitoring and control system. The sputum suction device includes an outer shell, an inner shell, and a closed sputum suction tube. The closed sputum suction tube passes The outer shell and the inner shell, the inner shell is provided with a transmission mechanism for automatically controlling the forward and backward push of the sputum suction tube, and the outer shell is provided with a swing mechanism for swinging the inner shell along the circumferential direction of the sputum suction tube; The monitoring and control system includes single-chip microcomputer, limit sensor, motor driver, infrared remote controller and display screen. In the present invention, the operation of the sputum suction device can be automatically controlled through the monitoring and control system, so the closed sputum suction tube can be controlled to perform automatic sputum suction operation on the patient instead of the manual sputum suction operation, which not only reduces the workload of medical staff, but also ensures the safety of patients. safety. The invention is easy to operate, can realize the automatic pushing control of the sputum suction tube without professional knowledge, can ensure the accuracy of pushing, and achieves efficient and safe sputum suction.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a system and method for automatic cleaning of respiratory tract sputum. Background technique [0002] At present, in the intensive care unit of the hospital, the death of critically ill patients due to airway blockage often occurs. At present, the main solution is to manually operate sputum suction. However, there are many deficiencies in manual operation of sputum suction. On the one hand, the operation requirements for medical staff are relatively high, because the objects of sputum suction are all critically ill patients and belong to high-risk groups. Tract bleeding affects the safety of patients. On the other hand, there are very high restrictions on medical staff, and it is necessary to arrange medical staff to take care of them 24 hours a day, so as to cope with the needs of patients with sputum suction at any time, including at night, which is very inconvenient...
