Breathing circuit for respiratory infectious diseases

Abstract

The invention relates to the field of medical instruments, in particular to a breathing circuit for respiratory infectious diseases. The breathing circuit comprises a conversion joint, the conversionjoint opposite to the machine end of a trachea cannula extends into a cannula as one, an isolation sleeve is inserted into and sleeved by the cannula orifice, the bottom of the isolation sleeve is provided with crossing grooves that sputum suction tubes can pass through, at least three branch parts of the crossing grooves are provided, the top of the isolation sleeve extends outwards to form a outer edge, the lower end surface of the lower outer edge is in stop fit with the end surface of the cannula orifice, the cannula orifice is provided with a sealing ring which is in limit fit with the lower outer edge of the isolation sleeve, and the sealing ring is provided with a sealing cover which is in sealing fit with the opening of the sealing ring; and a blocking plate is arranged below the isolation sleeve. The breathing circuit can protect medical personnel, effectively controls the spread of diseases such as bacteria and viruses, is convenient and practical in structure, not only protects the health of patients, but also protects the health of medical personnel and the air environment of medical places.

Description

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. 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 ...

[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
