Technique effect of the present utility model is: it have advantages of simple in structure, cost is low and be convenient for carrying, and for field first aid, can avoid directly contacting mouth to mouth with first-aid patients, convenient and sanitary.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of this utility model diaphragm.
The specific embodiment
As illustrated in fig. 1 and 2, it comprises the intubate 2 that is provided with check valve 1, and the outer wall of described intubate 2 is provided with the anti-ease cover 3 that prevents gas leakage that an oral area external form with people adapts, and anti-ease cover 3 is stretched out in the lower end of intubate 2.The part that stretch out intubate 2 lower ends is for being placed on by between rescuer's upper lower tooth, closed to prevent its ability to speak.
The upper end of described intubate 2 is provided with that an oral area external form with people adapts is convenient to the air blowing shield 4 of blowing, and described check valve 1 is located at 4 of intubate 2 and air blowing shields.Downward, 4 of air blowing shields are towards top for anti-ease cover 3.
Described check valve 1 comprises valve seat 5 and diaphragm 6, has passage 7 on valve seat 5, has " U " interruption-forming " U " shape valve 8 on diaphragm 6, and diaphragm 6 is located at the below of valve seat 5, and the valve 8 of diaphragm 6 covers passage 7 places at valve seat 5.
Described check valve 1 is threaded connection the upper end in intubate 2.Diaphragm 6 is extruded fixing.
The top of described check valve 1 is provided with the filter screen 9 that can stop drop to be come in and gone out.Check valve 1 can be made into one with air blowing shield 4, also can connect by the mode such as be spirally connected, and filter screen 9 can be located at the interior optional position of air blowing shield 4, also can fix by movable connected mode extruding such as employings are spirally connected.
The wall of described intubate 2 between anti-ease cover 3 and check valve 1 is provided with transpiration hole 10.When blowing, available finger is blocked transpiration hole 10, prevents that air-flow from escaping, and while stopping blowing, can unclamp the finger of blocking, and helps to discharge fast the intraoral pressure of patient.
