The utility model discloses an innovation technical point and beneficial effect lie in at least:

1. the device adopts a mode of abdicating the mouth part and the nose part of the human face to achieve a mode of gapless fit of the contour of the middle area of the face. Main part structure toper vomiting cover 1, reverse shutoff sleeve pipe 2, handle sleeve 5 all adopt hard material, can not take place to warp, can be so that the patient singlehanded lower part can easily realize the cover of pasting of oral area and nasal part periphery, and the effect of closely laminating can be reached to the seal ring 17 around the cooperation ring, can not take place the phenomenon that the side direction spills over. Compared with the existing simple film bag material for the vomiting bag 6, the patient needs to press two sides of the bag opening with both hands to cling to the face and then vomit, and the vomiting bag 6 needs to be controlled by both hands, so that other operations cannot be carried out. In the case of acute vomiting, there is a risk that the attached edge may splash out from the edge of the vomiting bag 6 if it is not tight. Simultaneously press the bag mouth edge through both hands and paste tight face and fix vomiting bag 6, because vomitus falls into can aggravate suddenly in vomiting bag 6 weight when vomiting, lead to vomiting bag 6 very easy slippage to drop in vomiting.

2. The reverse plugging valve arranged in the reverse plugging sleeve 2 can ensure that vomitus can smoothly pass through and enter the lower part when falling in the forward direction. When the device is reversely placed or rightly placed, when the vomitus at the bottom reversely impacts the reverse plugging valve, the reverse plugging cover 14 can be more tightly pressed on the port of the reverse plugging valve casing 13 under the action of gravity of the vomitus, so that the reverse plugging valve only allows one-way circulation from top to bottom and cannot reversely flow back. Meanwhile, when no vomitus falls in the vomit interval, the reverse blocking cover 14 can automatically seal under the action of the self balancing weight 16, and the smell of the vomitus in the lower vomit bag 6 can be isolated to a great extent. Compared with the prior art, the vomit bag 6 has no anti-reflux structure, can not shake greatly to avoid the vomit from spilling at any time during the vomit, has no shielding effect on the smell in the vomit bag 6, and can cause the strong discomfort of the patient easily due to the bad smell of the vomit.

3. This device major structure adopts rotatory screens fixed and screw thread rotation to press from both sides tight fixed dual mode, can fix and dismantle upper portion and lower part respectively, conveniently unpicks and washes, guarantees that the whole inside washing of device disappears and kills. Simultaneously in handle sleeve 5 inside vomiting bag 6 and the opening 6 two regions of vomiting bag that are provided with the winding respectively, the vomiting bag 6 of being convenient for outwards pull after using one by one is torn, and the suit is convenient, easy operation.

4. The inner side of the sealing washer 17 is integrally connected with a reverse rib 18, and the reverse rib 18 extends downwards in an inclined way towards the inner side surface, so that when the device is in a skew state or a shaking state, liquid vomitus in a flowing state in the device can not slide out of the port of the conical vomitus cover 1 along the inner wall of the conical vomitus cover 1 to cause liquid leakage or overflow, and the outer part of the device is polluted.

5. The water in the container 29 is intermittently sucked under negative pressure by connecting the water spraying pipe 26 with the negative pressure water sucking balloon 27, and water is sprayed through the front end port of the water spraying pipe 26 for cleaning the inside of the oral cavity of the patient. Can be to the inside instant cleanness of patient's oral cavity at the vomiting in-process, can remove the flavor to oral cavity inside again, very big increase patient's comfort degree. Meanwhile, the negative pressure water absorption balloon 27 can be continuously cleaned only by continuously extruding with one hand.

6. The both sides of toper vomiting cover 1 are provided with respectively by upper end outer wall punishment and hang rope 25 and can hang fixedly to patient's ear, have further guaranteed that whole device can not take place to drop.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
