Abstract

A pressure restricted type oxygen supply / attracting machine used for checking a fiberbronchoscope comprises an air mixer which is arranged in a shell; the air mixer is connected with a pressure regulator, a central oxygen supply system and an air compressor, wherein, an oxygen flow meter and an air flow meter are arranged between the air mixer and the air compressor and between the central oxygensupply system and the air compressor respectively; the pressure regulator is respectively connected with an attracting hole of the fiberbronchoscope and a central negative pressure source by a three-way pipe. The invention solves the problem of hypoxia for patients in fiberbronchoscope checking, and the patient can be supplied oxygen by the pressure restricted type oxygen supply / attracting machine without pulling out the fiberbronchoscope, thus avoiding complication, barotrauma and oxygen poisoning by inserting the fiberbronchoscope again and again, improving security and success ratio of thefiberbronchoscope, and extending the utilization scope of the fiberbronchoscope. The pressure restricted type oxygen supply / attracting machine has the advantages of simple structure, convenient use and high safety and is particular suitable for patients with critical illness and babies, especially a new born baby.

Description

technical field [0001] The invention relates to a medical device, in particular to a pressure-limited oxygen supply / suction machine for fiberoptic bronchoscopy. Background technique [0002] Fiberoptic bronchoscope is more and more widely used clinically, and it plays an increasingly important role in pediatric clinical diagnosis and treatment. With in-depth research, the scope of application of fiberoptic bronchoscopy will become wider and wider. In foreign countries, fiberoptic bronchoscope has been widely used in neonatal patients. In China, there are also individual reports of fiberoptic bronchoscopic application in neonatal patients. The main complication of fiberoptic bronchoscopy is hypoxemia. In critically ill patients, children, especially newborns, the incidence and severity of hypoxemia are more obvious. Therefore, fiberoptic bronchoscopy and treatment cannot be performed. , thus delaying the disease until the patient dies. [0003] Chinese Patent Document No. ...
