Breathing Circuits for Respiratory Transmitted Diseases

Abstract

The invention relates to the field of medical devices, in particular to a breathing circuit for respiratory diseases. Including the conversion joint, the conversion joint opposite to the end of the endotracheal intubation machine is integrally extended with an intubation tube, the intubation tube mouth is inserted with an isolation sleeve, and the bottom of the isolation sleeve is provided with a cross-shaped groove that can be inserted into the sputum suction tube There are at least three forks in the intersecting grooves, and the lower end surface of the lower outer edge formed by the outward extension of the top of the insulating sleeve cooperates with the end surface of the intubation nozzle. The intubation nozzle is provided with The sealing ring is limitedly matched with the lower outer edge of the isolating sleeve, and the sealing ring is provided with a sealing cover which is sealingly matched with the ring opening of the sealing ring; a blocking plate is provided under the isolating sleeve. The invention can protect medical personnel, effectively control the spread of diseases such as bacteria and viruses, has a convenient and practical structure, and not only protects the health of patients but also the health of medical personnel and the air environment in medical places.

technical field [0001] The invention relates to the field of medical devices, in particular to a breathing circuit for respiratory transmission diseases. Background technique [0002] In the use of existing medical devices, the breathing circuit is an important medical device in the process of general anesthesia, mechanical ventilation and respiratory support for critically ill patients. Unobstructed, etc. have an irreplaceable role; but in the process of respiratory support, the respiratory tract will produce sputum and other secretions. If excessive secretions are not eliminated in time, it will lead to atelectasis, lung infection, and decreased oxygen saturation.

[0002] In the use of existing medical devices, the breathing circuit is an important medical device in the process of general anesthesia, mechanical ventilation and respiratory support for critically ill patients. Unobstructed, etc. have an irreplaceable role; but in the process of respiratory support, the respiratory tract will produce sputum and other secretions. If excessive secretions are not eliminated in time, it will lead to atelectasis, lung infection, and decreased oxygen saturation. Symptoms such as respiratory distress occur; usually medical personnel need to remove the adapter 2, and use a suction tube to insert the end of the endotracheal tube 1 from the machine and then into the patient's respiratory tract to remove secretions from the patient's respiratory tract; especially for general anesthesia and mechanical ventilation. The patient is completely unable to expel sputum and needs to use a suction tube to expel secretions

However, during the suction operation, the suction tube will touch the mucous membrane in the patient's trachea, thereby inducing a protective airway reflex, causing the secretion to be ejected with the patient's exhaled gas and aerosol, and it is easy to splash on the face of the medical staff , may cause health hazards to medical staff; if patients with respiratory diseases, the exhaled gas, aerosol and secretions not only pollute the environment, but also pose a challenge to the hospital's infection control, and will cause great harm to medical staff. the threat of
