Problems solved by technology

However, in the face of high-viscosity thick sputum, bronchoscope suction often fails to suck it out, and eventually the patient cannot be rescued in time
If a higher negative pressure is used for suction, it is easy to cause damage to tracheal tissue or pulmonary edema

Abstract

The invention discloses a wire conduction ultrasonic bronchoscope for liquefying thick sputum. The wire conduction ultrasonic bronchoscope comprises a probe, a catheter, a handle and a transducer, wherein the catheter comprises a conduction wire; the probe is connected with one end of the catheter, and the other end of the catheter is connected with the handle; and the conduction wire penetrates through the catheter, one end of the conduction wire extends out of the handle and is connected with the transducer, and the other end of the conduction wire extends out of the probe. The transducer generates ultrasonic vibration and transmits the ultrasonic vibration to the probe through the conduction wire to perform ultrasonic vibration and cavitation on the thick sputum, so that the local temperature is increased, the thick sputum is liquefied and the binding force of the thick sputum is reduced, and favorable conditions are created for sputum suction of the bronchoscope.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a wire conduction ultrasonic bronchoscope for liquefying thick phlegm. Background technique [0002] According to the case reports of COVID-19 and the anatomical analysis of deceased patients, it was found that COVID-19 would cause the patient's lungs and trachea to secrete a large amount of sputum, which in turn would block the alveoli and trachea, causing phlegm obstruction. When the sputum blocks more alveoli and trachea, the patient cannot breathe normally, the blood oxygen concentration drops severely, and eventually causes tissue and organ damage, shock and even death. [0003] Bronchoscopic sputum suction is an important method to solve the problem of sputum blockage of alveoli and trachea in patients with new coronary pneumonia, especially in critically ill patients. However, in the face of high-viscosity thick sputum, bronchoscope suction often fails to suck...
