Abstract

The utility model relates to a breathing mask which is suitable to the surgical of the patient of oral jaw surgery. The structure of the existing breathing mask is improved by the breathing mask. When the breathing mask is used, the hypoventilation problem of the patient who dose not breathe is solved by increasing the spiracular total area. The required surgical maxillofacial region is avoided by an elastic wearing rod which is suited for the head of the patient and fixed in a style of longitudinal position, and this structure is convenience for the wear of the patient as well. An adjustment sheet with free rotation and a plurality of circular holes fixed on the external side of the breathing mask can adjust the effective ventilation area conveniently and extend the use field of the utility model. The utility model has simple structure and has the advantages of convenience and availability.

Description

Breathing mask

(1) technical field:

This utility model relates to a kind of breathing mask, the breathing mask that uses when especially jaw surgical patient in oral cavity performs the operation.

(2) background technology:

In the prior art, when oral cavity jaw surgical patient performs the operation,,, often need wear breathing mask for avoiding causing the patient respiration difficulty owing to the disinfecting towel of bedding, singly be close to mouth and nose.The breathing mask of clinical no special use can be used, and often replaces with oxygen absorption mask.This oxygen absorption mask is approximately conical cup-shaped, be buckled in during use on patient's the mouth and nose, rim of a cup has ring-shaped gasbag, in be filled with gas, and there is a valve to link to each other with air bag, it is coniform that cup is approximately, the cup front portion has a spot of passage, in addition, this position also has one to be used to connect the connection tube of oxygen hose, a fixture that is used for conveniently wearing, and its shortcoming is: because the passage in the oxygen absorption mask is few, when the oxygen uptake patient does not use this face shield, often feel uncomfortable in chest, dyspnea because of hypoventilation; In addition, after band need laterally lie in brain through the jaw face by fixture when this face shield was worn, often operation is constituted influence.

(3) summary of the invention:

This utility model aims to provide a kind of breathing mask that uses when being suitable for oral cavity jaw surgical patient and performing the operation.

Technical solution of the present utility model is as follows:

A kind of breathing mask, be and be similar to conical cup-shaped, rim of a cup has ring-shaped gasbag, and there is a valve to be attached thereto, cup has some passages on the anterior side, and in addition, this position also is fixed with one and is used to connect the connection tube of oxygen hose, a fixture that is used to wear, it is characterized in that: described passage is a plurality of, and its area sum is more than or equal to the required area of eupnea ventilation.

This technical scheme has solved the problem that oxygen uptake patient not uses the hypoventilation of this face shield.

Further technical scheme is:

Fix the corresponding arcual elasticity of the capitiform with the people of vertically settling on the described fixture and wear bar, extend to pillow through forehead, the crown when this is worn bar and wears after.

This technical scheme can be worn on breathing mask on the head easily, has avoided the jaw face simultaneously, has avoided the probability of influence operation.

Above-mentioned elasticity is worn bar and also can be adopted telescopic structure of length such as antenna to draw the pole structure to adapt to the patient of multiple capitiform.

Another improvements are:

The anterior cup of breathing mask is the taper shape of rule, described passage is the circular hole of the spacing of even regular distribution on the anterior conical surface of cup greater than the aperture, this breathing mask comprises that also one has the adjustment sheet of a plurality of same circular holes on it, this adjustment sheet has formed a round table-like space, and it is connected in the outside, cup front portion and free to rotate.Rotate this adjustment sheet, the registration of the circular hole on the circular hole on the dependence adjusting adjustment sheet and the anterior cup of breathing mask is the area of scalable effective ventilatory volume.

Technique scheme makes this utility model both be adapted to the oxygen uptake patient and uses, and being adapted to not again, the oxygen uptake patient uses.

This utility model is simple in structure, easily and effectively, and one-object-many-purposes.

(4) description of drawings:

Below with reference to drawings and Examples this utility model is described in further details:

Accompanying drawing 1 is the structural representation of this utility model embodiment.

Each sequence number is respectively in the accompanying drawing 1: 1, wear bar; 2, connection tube; 3, hold-down nut; 4, passage; 5, adjustment sheet; 6, ring-shaped gasbag; 7, valve

(5) specific embodiment:

Referring to accompanying drawing 1, this utility model embodiment totally is and is similar to conical cup-shaped, rim of a cup has ring-shaped gasbag 6, make that breathing mask and patient are facial closely to be contacted and increase comfort level, and have a valve 7 to link to each other with air bag, so that inflation, the cup front portion is the taper shape of rule, have the passage 4 that wait circle of some equally distributed spacings greater than the aperture on the anterior side, the area sum of these passages is greater than the required area of eupnea ventilation.An adjustment sheet 5 that is used to regulate the effective ventilatory volume area that has a plurality of round holes such as same is equipped with in the cup front portion outside, and this adjustment sheet has formed a round table-like space, and it is free to rotate.In addition, the cup front portion also is fixed with the end that a connection tube that is used to connect oxygen hose 2, corresponding arcual elasticity of the capitiform with the people of vertically settling wear bar 1 and is fixed in the cup front portion by hold-down nut 3, extend to pillow through forehead, the crown when this other end of wearing bar is worn after.Like this, breathing mask can be worn easily.When this adjustment sheet turns to overlapping fully of circular hole on the cup of the circular hole regulated on the adjustment sheet and breathing mask, effective ventilation area maximum, the breathing mask of this moment is fit to not oxygen uptake patient use.When this adjustment sheet turns to staggering fully of circular hole on the cup of the circular hole regulated on the adjustment sheet and breathing mask, the effective ventilation area is zero, the breathing mask of this moment becomes an oxygen absorption mask, and patient relies on fully from the connection tube that connects oxygen hose and obtains oxygen.

This utility model has solved the problem of hypoventilation when the oxygen uptake patient does not use face shield by increasing the gross area of passage; Wear bar by installing the corresponding elasticity of the capitiform with the people of vertically settling additional, both made things convenient for and worn, needing to have avoided the jaw face of operation again; Have a plurality of circular holes and adjustment sheet free to rotate by installing one additional in the breathing mask outside, conveniently adjusted effective ventilation area has increased the scope of application of the present utility model.This utility model is simple in structure, easily and effectively, and one-object-many-purposes.

Certainly, under inventive concept of the present utility model, this utility model has multiple form of implementation, as the adjustment sheet structure is not to regulate the only resource of effective ventilation area, the specific constructive form that technique scheme is also not exclusive, also can reach the purpose of regulating the effective ventilation area as on breathing mask, being connected to the breather that can control open and close, those skilled in the art read need not pay after this description creative work promptly similarly replacement scheme reveal again, just do not described in detail at this.
