Respirator system having functions of expectoration and vibration

Abstract

The invention relates to a respirator system having functions of expectoration and vibration. The respirator system comprises a pressure generator or flow generator arranged on a respirator, one or more sensors located on gas channel pipelines of the respirator and a central processing unit device, wherein the pressure generator or flow generator is connected with the central processing unit device; each sensor is connected with the central processing unit device; and under the assistance of the pressure generator or flow generator and each sensor, the central processing unit device can deliver respiratory gases for treating the disease of a patient object to the trachea of the patient object under definite pressure characteristics or under definite volume characteristics to be used for treating the disease of the patient object. Through the adoption of the respirator system provided by the invention, the functions of respiration and expectoration can be integrated to one equipment, sothat the treatment effect of expectoration can be greatly improved.

Description

technical field [0001] The invention belongs to the field of medical and health technologies, and in particular relates to a ventilator system with functions of expectoration and oscillation. Background technique [0002] For patients who are on a ventilator, especially after the artificial airway is established, the cough reflex is weakened, or due to severe decline in lung function, respiratory muscle weakness, etc., most of them cannot expel sputum spontaneously, which can easily cause secretions to stay and block the airway Make lung infections worse. Therefore, for mechanically ventilated patients, manual sputum removal is required on a regular basis. [0003] At present, it is commonly used clinically to suck sputum with a sputum suction tube, but the invasive sputum suction method of sputum suction tube is easy to damage the airway due to the high local negative pressure and the insertion and movement of the catheter. Cause injury or airway scarring, at the same tim...

AI Technical Summary

Problems solved by technology

[0007] Use the sputum machine alone: ​​the sputum machine has the ability to inflate the patient's lungs, for example: Cough Assist E70, there are two defects in such equipment, first, the air source (fan) of the equipment is only one, inhalation and exhalation The function is only to switch the airway between the suction port and the exhaust port of the fan through the valve, which brings the risk of secondary pollution and cross-infection of exhaled matter
