Sputum suction device with breath simulating function

Abstract

The invention belongs to the technical field of medical instruments, and achieves a sputum suction device with a breath simulating function. The content mainly relates to the method that through simulating of breath of a patient, influence on work of a breathing machine in the working process of the sputum suction device is avoided. The sputum suction device is different from a traditional sputum suction device, the sputum suction device and the breathing machine are connected to a breathing circuit of the patient in parallel, through the self learning function of the sputum suction device, the mechanical ventilation characteristic of the patient is learned, and through simulating of a breath process of the patient, the influence on the breathing machine due to the cutting off of mechanical ventilation circuit is avoided in a sputum suction process of the sputum suction device. The sputum suction devices simulates the breath process of the patient, the influence on the breathing machine due to the cutting-off of mechanical ventilation circuit is avoided in the sputum suction process, influence on mechanical ventilation by the patient after the sputum suction is reduced, and therefore the sputum suction device has excellent popularizing prospects.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a sputum suction machine with the function of simulating breathing. Background technique [0002] The sputum suction machine effectively clears the secretions in the airway through the mouth, nasal cavity and artificial airway according to the principle of negative pressure, keeps the airway unobstructed, improves alveolar ventilation and ventilation function, and is widely used in the nursing of airway management of mechanically ventilated patients. [0003] At present, when the existing sputum suction machine is working, it is necessary to cut off the patient's mechanical ventilation circuit, because the ventilator cannot suck air from the patient's lungs, which will cause the ventilator to alarm, and the next time the patient's lungs are inflated, the air will be filled. A larger flow of air, which again causes the ventilator to alarm, and causes the patient's lung damag...
