Embodiment 1

[0042] Cooperate figure 2 and image 3 As shown, in this embodiment, each side airbag 2 is set separately, so that the middle part of the digestive drainage tube can be directly inserted into the junction of adjacent side airbags 21, and the side edges on both sides of the digestive drainage tube Adjusting the air pressure of the air bag 21 can seal the digestive drainage tube and the side air bag 21 to prevent air leakage, and it is not easy to cause the sealing and blockage of the digestive drainage tube, which can solve the problem that the existing medical mask has a digestive drainage tube that will damage the mask The sealing problem between the air bag 2' and the patient's cheek; in addition, the middle part of the digestive drainage tube can be directly pulled out from between the side air bags 21 on both sides to directly remove the digestive drainage tube, which will not cause the digestive drainage tube to attach Pollutants pollute the mask airbag 2. It should be...

Embodiment 2

[0046] Cooperate Figures 4 to 6 As shown, in the present embodiment, a sealing partition 5 is provided in the mask body 1, and the sealing partition 5 divides the inner cavity of the mask body 1 into a nose cavity 12 and a mouth cavity 13, and the nozzle 11 and the mouth cavity The nose cavity 12 communicates, and the sealing partition 5 is provided with a vent hole 51, and the vent hole 51 is provided with a one-way ventilation device 6 that can make gas flow from the mouth cavity 13 to the nose cavity 12 in one direction; the sealing The lower end of the partition 5 is provided with an intermediate airbag 7 for sealing and separating the nasal cavity 12 and the mouth cavity 13. The intermediate airbag 7 is used to interfere with the face between the upper lip and the nose. The intermediate airbag 7 is not connected to each side airbag 21. , the middle airbag 7 is equipped with an air nozzle 3, and the two ends of the middle airbag 7 are sealed with the mask airbag 2; when t...

Abstract

The present invention discloses an air leakage prevention medical face mask. The face mask comprises a face mask body; the upper end of the face mask body is provided with a pipe orifice; the peripheral edge of the lower end of the face mask body is provided with a face mask airbag in seal fit with the peripheral edge of the lower end of the face mask body; the face mask airbag comprises a plurality of side airbags which are annularly distributed on the peripheral edge of the lower end of the face mask body and can be in seal fit with one another after being inflated; the side airbags are connected with the peripheral edge of the lower end of the face mask body and do not communicate with one another; and each side airbag is equipped with an air nozzle. The face mask airbag comprises the plurality of side airbags which are annularly distributed on the peripheral edge of the lower end of the face mask body, and the side airbags can be in seal fit with one another after being inflated, so that the side airbags can be subjected to air pressure adjustment for enabling the side airbags to be matched with the faces of different patients, and the face mask airbag can closely abut againstthe faces of the patients to prevent air leakage.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an anti-leakage medical mask. Background technique [0002] Cooperate figure 1 As shown, at present, the medical mask used for clinically implementing anesthesia or oxygen supply to patients includes a mask body 1', the upper end of the mask body 1' is provided with a nozzle 11', and the peripheral edge of the lower end of the mask body 1' is provided with a nozzle 11' connected with the mask body 1'. The lower edge of the mask airbag 2' is hermetically fitted, and one side of the mask airbag 2' is provided with an air nozzle 3' for inflation and deflation. The shortcoming that existing medical mask exists mainly contains: [0003] (1) Since the patient's facial appearance is different, and the current mask airbag 2' has an integrated structure, the mask airbag 2' cannot completely fit the patient's face during pressurized oxygen supply, and air leakage will occur. Even hypoxe...
