Negative-pressure suction device with automatic pressure regulation

Abstract

The invention discloses a negative-pressure suction device with automatic pressure regulation. The negative-pressure suction device comprises a liquid collecting bottle, a liquid concentration sensor,a negative-pressure bottle body and a pressure regulating meter, wherein a connecting cover body is mounted on the upper end face of the liquid collecting bottle, a liquid collecting bag is fixed inside the connecting cover body, a left pipe connector penetrates through the upper end face of the connecting cover body, the liquid concentration sensor is mounted at an upper port of the left pipe connector, the pressure regulating meter is arranged at the right upside of the liquid concentration sensor, the negative-pressure bottle body is mounted at a lower port of the pressure regulating meter, a gage float is arranged inside the negative-pressure bottle body, and a negative-pressure interface is mounted on the side end face of the negative-pressure bottle body. The negative-pressure suction device with automatic pressure regulation has the main characteristics that automated negative pressure regulation can be achieved during flushing liquid suction and diversion liquid suction in phlegm sucking and surgery operating processes through automatic pressure regulation, so as to replace manual regulation by medical care personnel during appropriate negative pressure selecting as required, and thus, the complexity of operations of the medical care personnel is lowered.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure suction device with automatic pressure regulation. Background technique [0002] Tracheal suction is the primary and key measure in the airway management of mechanically ventilated patients. Its purpose is to keep the airway unobstructed, prevent partial or complete airway intubation obstruction, and play an important role in the control of respiratory infection. Suction operation itself will increase the risk of certain complications, including airway mucosal injury, infection, atelectasis, bronchospasm, hypoxemia, irritant asphyxia, increased intracranial pressure, and severe cases may cause cardiac arrest. Sudden arrest or even death. [0003] Negative pressure is the driving force of sputum suction operation. Some data show that the magnitude of suction negative pressure is directly proportional to the degree of airway mucosal damage. Different su...

Problems solved by technology

[0004] The purpose of the present invention is to provide a negative pressure suction device with automatic pressure regulation, which solves the problem that the existing suction devices on the market need to manually adjust the suitable negative pressure due to the difference in the thickness of the sputum when performing the sputum suction operation. Increased the workload of medical staff, there are problems of blind and cumbersome operation
