Detailed Description

The tracheostomy mask is a device for inhaling oxygen of a patient through tracheotomy, but the prior art tracheostomy mask clinically used in hospitals has a plurality of defects, such as inconvenient cleaning of sputum flowing out and expectoration at the tracheotomy of the patient, and the patient can be cleaned only by removing the mask; the height cannot be adjusted and is easily jacked up by the outer-end autogenous cutting pipe, so that the oxygen supply effect is poor; the expiration status cannot be adjusted according to the difference and feeling of the patient, and the practicality and the patient experience can be greatly improved by overcoming the defects.

The air-cutting mask provided by the invention has the functions of heightening and adjusting the exhalation state, and by arranging two exhalation holes (an air outlet and an air exhaust hole) with adjustable air output/aperture size and one-way air exhaust hole, an openable and closable sputum suction opening is additionally arranged, and the telescopic pipe is arranged, so that the height of the air-cutting mask can be changed, patients with different respiratory states or respiratory requirements can be conveniently satisfied, the practicability of the air-cutting mask is improved, the oxygen supply effect of the air-cutting mask can be improved, the external splashing of secretion which is expectorated by choking is prevented, and the sputum suction operation is convenient.

For convenience of description, the exhalation vent (vent hole) that can adjust the amount of gas out/the size of the aperture may be referred to herein simply as an "adjustable vent hole".

The term "autogenous cutting mask" may also sometimes be referred to herein as a "mask," autogenous cutting mask, "or" autogenous cutting shield. For simplicity of description, the "mask" may be abbreviated, and they are used interchangeably in the same sense. Similarly, the term "strap" may also be referred to as a "securing strap," "tie strap," or "bungee cord"; the term "exhalation port" may also be referred to as "exit port" or "vent hole" or the like.

The design improvement comprises that the left side and the right side of the air-breathing face cover are respectively provided with an air-breathing hole, and the air-breathing mode of the air-breathing hole can be adjusted by rotating the rotary disk. The middle position is provided with a sputum suction hole which can be closed when not in use. And the inside of the autogenous cutting mask cover is provided with a telescopic extension area, so that the placement position of the autogenous cutting mask can be heightened. The adjusting rotary disc on the breathing hole can effectively adjust the breathing amount/aperture size and the breathing mode, and adapt to the breathing requirements of different patients, for example, when the oxygen demand of the patients is high, one-way breathing can be selected, the concentration of the diluted inhaled air by air is reduced, and the oxygen concentration of the inhaled air is ensured; when the carbon dioxide of the patient is accumulated, a large-aperture expiration Kong Chuqi can be selected to increase the gas circulation; the type of the bilateral breathing holes can be freely selected, and the secretion splashing caused by choking can be reduced.

The autogenous cutting face mask of the invention can adapt to patients with different autogenous cutting guide pipes and different breathing states by means of the design of the adjustable aperture size and the breathing hole of the breathing way, and conforms to clinical indexes, thereby improving the applicability of the face mask.

As will be readily appreciated by those skilled in the art, the present invention differs from the prior art mainly in the improvement of mechanical construction, and each component may be made of the same functional component materials in the prior art mask or other general medical exhalations, for example, the mask body may be made of transparent or opaque soft polymer materials such as medical PVC materials, silica gel, etc.; the turntable may be made of a hard plastic. The choice of such prior art materials does not increase the production costs too much, which is economically advantageous.
