Multifunctional non-invasive ventilator mask

Abstract

The invention discloses a multifunctional non-invasive ventilator mask, and relates to the field of medical equipment. The mask comprises a mask shell. The back end surface of a mask ring is providedwith a pressure-sore-proof sealing device, and the front side of the mask shell is provided with an oral sealing care device. The pressure-sore-proof sealing device comprises two annular elastic air tubes; each mounting groove is provided with an elastic air tube in a matching mode, the right side of each elastic air tube is communicated with an air outlet tube, and the left side of each elastic air tube is communicated with an air inlet branch. The oral sealing care device comprises a sealing tube. The rear part of the sealing tube is cylindrical, and the front part is elliptical. The front part of the mask shell is provided with an insertion hole, the rear part of the sealing tube is in insertion sealing connection with the insertion hole, and a front port of the sealing tube is in insertion fit with a sealing cover. The mask has the advantages of utilizing the modes of bonding position change and heat conduction and cooling to prevent pressure sores, and achieving stable pressurizing and air supply during oral care.

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
