The specific embodiment

For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present invention and beneficial effect more, the applicant general elaborates in the mode of embodiment below, but all be not restriction to the present invention program to the description of embodiment, any according to the present invention's design done only for pro forma but not substantial equivalent transformation all should be considered as technical scheme category of the present invention.

Please be referring to Fig. 1 and Fig. 2, provided preferably by nonmetallic materials such as plastics or lucite is that make and nose suitable face shield body 1 shape and human organ, this face shield body 1 has a cover chamber 11, cover chamber 11 under user mode towards by the rescuer.Be combined with an air bag 12 on face shield body 1 and towards the position, edge of a side of covering chamber 11, the self-evident effect of this air bag 12 is to make face shield body 1 and formed sealing by rescuer's fabric.Middle position one formation at face shield body 1 has a socket 13, and socket 13 is essentially an insertion pipe, thereby formation has a socket cavity 131 that communicates with cover chamber 11.Each formation has a webbing to buckle 15 back to the edge of the wall body of cover chamber 11 1 sides and in aspectant position at face shield body 1, placed or claimed to wear at a pair of webbing button 15 and be furnished with a webbing 151, in use, webbing 151 is placed on by rescuer's head, preferably, webbing 151 adopts elastic cord or other similarly to have the belt of flex effect.

Consisting of on face shield body 1 and in the side one back to cover chamber 11 has one spigot jointly 14, and spigot joint 14 is furnished with a gag 141 at this.When the rescuer to after by rescuer artificial respiration a period of time, and had inadequate when the respiratory function by the rescuer, can spigot joint 14 be connected with the ventilation channel of oxygen supply apparatus such as oxygen cylinder by this, thereby can not occur manually and the discrepancy between the apparatus oxygen supply.

Be equipped with an air filter 2 in the side of aforesaid socket 13 towards cover chamber 11, preferably but not the structure of the air filter 2 that definitely is limited to is as follows: comprise a filter membrane seat 21, a filter membrane 22 and a filter membrane tabletting 23, filter membrane seat 21 is extended with a connector 211 towards the central part of a side of socket 13, connector 211 and socket 13 insertings, this connector 211 consists of one group of passage 2111, makes connector constitute the hollow out structure by this passage 2111.Filter membrane seat 21 consists of towards a side of filter membrane 22 a filter membrane container cavity 212 just as basin shape, and filter membrane 22 is laid in this filter membrane container cavity 212, filter membrane tabletting 23 and filter membrane container cavity 212 scarves, and by it filter membrane 22 is pushed down.Shown in figure, filter membrane tabletting 23 has one group of through hole 231, makes filter membrane tabletting 23 form the hollow out structure by this group through hole 231.Aforesaid filter membrane 22 preferred non-woven fabrics or the similar materials with minute aperture that use also can use the porous sterilization film that is impregnated with disinfectant solution.

Technical essential as technical scheme provided by the invention, be inserted with a preventer at aforesaid socket 13 back to the end in described cover chamber 11, preferred preventer comprises a preventer body 3, this preventer body 3 comprises a valve body 31 and a valve block 32, valve body 31 has a socket connector 311 towards the central part formation of a side of socket 13, this socket connector 311 inserts in the aforesaid socket cavity 131, communicate with socket cavity 131, and socket cavity 131 communicates with cover chamber 11 undoubtedly, the central part of valve body 31 side outward, that is to say that valve body 31 has a blowing nozzle 312 back to the central part formation of a side of socket connector 311, this blowing nozzle 312 is for the rescuer.Wall body at the middle part of valve body 31 offers an outlet chamber 313, and this outlet chamber 313 communicates with the blowing nozzle through hole 3121 of blowing nozzle 312 and with valve pocket 314.Valve block 32 is fixed in the valve pocket 314, and is positioned at the below of aforesaid outlet chamber 313.The gas of breathing out and enter in the valve pocket 314 of being sued and laboured can only be drawn from outlet chamber 313, because when the rescuer stops to blow, under gas pressure corresponding to the valve block 32 at the position, aperture of blowing nozzle through hole 3121 pathway closure with blowing nozzle through hole 3121, thereby ensured safe and sanitary, avoided by the rescuer rescuer's communicate illness.

Use when of the present invention, webbing 151 is placed on by rescuer's head, the cover chamber 11 of face shield body 1 is aimed at by rescuer's mouth nose, the rescuer aims at blowing nozzle 312 and blows, air-flow top is opened valve block 32 and is entered cover chamber 11 through valve pocket 314 and socket cavity 131 successively, under the effect of the pressure in cover chamber 11, the air (oxygen) in the cover chamber 11 is entered by in rescuer's body.When the rescuer aimed at blowing nozzle 312 air blowing, because valve block 32 is unlocked, with outlet chamber 313 sealings, vice versa just for the valve block 32 of therefore opening.

By the above-mentioned explanation of applicant, can know that fully the present invention program has the strong point of safety and sanitation with respect to prior art
