Multi-functional non-invasive breathing machine face mask

Abstract

The invention discloses a multi-functional non-invasive breathing machine face mask, and relates to the field of medical facilities. The multi-functional non-invasive breathing machine face mask comprises a face mask housing. The rear end face of a face mask ring is provided with a pressure-sore-resistant sealing device. The front side of the face mask housing is provided with an oral cavity sealing nursing device. The pressure-sore-resistant sealing device comprises two annular elastic air pipes. The right side of each elastic air pipe is communicated with an air outlet pipe, and the left side of each elastic air pipe is connected with an air inlet branch pipe. The end of the air inlet pipe is communicated with a three-way control valve. A permanent magnet is inserted and installed in a groove. The oral cavity sealing nursing device comprises a sealing pipe. The sealing pipe is formed by sealing and butting two upper and lower semi-bodies. The front part of the face mask housing is provided with an inserting hole. The rear part of the sealing pipe is in inserting and sealing connection with the inserting hole. A port at the front of the sealing pipe is in inserting fit with a sealing cover. The multi-functional non-invasive breathing machine face mask has the beneficial effects of achieving the pressure-sore-resistant effect by using an adhesion position change and heat conduction temperature reduction mode, and synchronously and stably pressurizing and feeding air while nursing an oral cavity.

Description

technical field [0001] The invention relates to the technical field of medical equipment. Background technique [0002] Non-invasive positive pressure ventilation is mainly used to connect the man-machine interface through nasal or oronasal masks to treat toxic respiratory failure. When using an oronasal mask, it is necessary for the patient's face to be well sealed with the mask, and pressure sores are likely to occur under pressure if used for a long time; at the same time, due to long-term sealing contact, the temperature at the contact position is also likely to be high, which is easy to cause Discomfort and pressure sores, etc., in many mask designs, the temperature of the contact position is not considered, and the temperature of the contact position cannot be well cooled; when using an oral and nasal mask, due to the need for pressurized air supply, it is very influential Necessary care for the patient's oral cavity, insufficient operating space or inconvenient opera...

Problems solved by technology

When using an oral and nasal mask, it is necessary for the patient's face to be well sealed with the mask, and pressure sores are likely to occur under pressure if used for a long time; at the same time, due to long-term sealing contact, the temperature at the contact position is also likely to be high, which is easy to cause Discomfort and pressure sores, etc. In many mask designs, the temperature of the contact position is not considered, and the temperature of the contact position cannot be well cooled; when using an oral and nasal mask, due to the need for pressurized air supply, it is very influential Necessary care for the patient's oral cavity, insufficient operating space or inconvenient operation, affecting the nursing effect
