Abstract

The utility model provides an improved structure of gas outlet holes of an oxygen face mask. A soft valve plate with elasticity is arranged at the ends of a plurality of gas outlet holes of the face mask. A convex body is arranged on a center post at the center of the lateral surface of the valve plate. The face mask is clamped and fixed at a neck part between the valve plate and the convex body, so that the valve plate is tightly combined and is difficult to fall off, and thus, a patient can inhale more pure oxygen without inhaling the outside mixed air.

Description

The structure-improved of oxygen face mask venthole

Technical field

This creation system refers to the valve block of a kind of innovation and difficult drop-off especially relevant for a kind of structure-improved of oxygen face mask venthole, can make sufferer can suck more purity oxygen person.

Background technology

Press; General traditional type covers on the oxygen face mask that sufferer face supply oxygen is given sufferer; As shown in Figure 1, these face shield 100 top cordings have a sheet metal 101, so that be clipped on the sufferer bridge of the nose; The air inlet pipe 102 of face shield 100 bottoms can be connected to oxygen supply pipe 1021, and face shield 100 central both sides are respectively equipped with several ventholes that is arranged in annular 103; When sufferer is being drawn oxygen simultaneously; Because of open venthole 103 is not sealed; When so sick loyalty is drawn oxygen by air inlet pipe 102; Blended air for public use also can be sucked in the patient by open venthole 103, and the mode of this kind supply oxygen can't provide more purity oxygen to be supplied to sufferer, thereby haves much room for improvement.

Therefore the dealer is arranged is the oxygen face mask of research and development second type; As shown in Figure 2; These face shield 200 tops also have a sheet metal 201, so that be clipped on the sufferer bridge of the nose, the air inlet pipe 202 of face shield 200 bottoms can be connected to oxygen supply pipe 2021; Face shield 200 central both sides are respectively equipped with several ventholes that is arranged in annular 203; The valve block 204 that one salient point, 2031, one soft materials are set outside annular venthole 203 mediads is to utilize the centre bore 2041 of valve block 204 to be nested with on salient point 2031, so that valve block 204 closes each venthole 203; Yet 204 of this soft valve blocks are fixed on the slight salient point 2031, are easy to cause come off, and under valve block 204 was coming off state, sufferer just can't be drawn more purity oxygen, so still treat the improver.

Novel content

Edge is that the main purpose of this creation is to provide a kind of structure-improved of oxygen face mask venthole, wishes design by this, provide a kind of soft valve block closely to be combined on the face shield, and difficult drop-off can suck more purity oxygen for making sufferer, is its purpose person.

Take off purpose for before reaching, the face shield that this creation designed, this face shield top has a sheet metal, and the air inlet pipe of face shield bottom is connected to the oxygen supply pipe, and face shield central authorities both sides are respectively equipped with several ventholes and are arranged in ring-type,

One valve block system is installed in several nose ends of giving vent to anger; This valve block side central authorities tool one newel; The nearly valve block end of newel tool one convex body forms cervical region between convex body and the valve block, several venthole central authorities tool one centre bores of face shield; This centre bore is run through in stem system among the valve block, and face shield system fixes on the cervical region between valve block and the convex body.

In order to let your juror that this creation is had understanding further, Zi Zuo with graphic this creation of detailed description as follows:

The specific embodiment

See also shown in one of Fig. 3 and Fig. 3; This creation supplies the face shield 10 of patient's use; These face shield 10 tops have a sheet metal 11 and can be clipped on the bridge of the nose of sufferer; The air inlet pipe 12 of face shield 10 bottoms can be connected to oxygen supply pipe 121, and face shield 10 central both sides are respectively equipped with several ventholes 13 and are arranged in ring-type;

Several ventholes 13 can be sealed up by the valve block 14 of this creation improvement, this valve block 14 sides central authorities tool one newel 141, and newel 141 nearly valve block 14 end tools one convex bodies 142 form cervical region 143 (like Fig. 3 A) between convex body 142 and the valve block 14; Several venthole 13 central tool one centre bores 131 of face shield 10; Stem 141 is to run through this centre bore 131 among the valve block 14; User is haled this newel 141 with hands; Make face shield 10 fix on the cervical region 143 between valve block 14 and the convex body 142, so that valve body 14 is combined closely with face shield 10, this kind compound mode makes valve block 14 be not easy to come off.

Moreover; The valve block 14 of this creation is a soft materials; Can be for materials such as silica gel, rubber or plastics, because of soft silica gel, rubber or plastics itself have elasticity, when sufferer is felt elated and exultant (carbon dioxide spues); The external world's (shown in Fig. 4 arrow) that can spue by venthole 13 ends of face shield 10, and the elastic valve block 14 of soft tool can return to the state of sealing at once; When sufferer is drawn oxygen by the air inlet pipe 12 of face shield 10; Valve block 14 can seal up the venthole 13 of face shield 10; To prevent extraneous blended air inspiration face shield 10 interior entering in the patient, therefore can make sufferer can suck more purity oxygen, and can not suck extraneous blended air person.In sum, the structure-improved of this creation oxygen face mask venthole, several nose ends of giving vent to anger that mainly lie in general oxygen face mask are installed a soft valve block; Tool one convex body on the stem when user passes the centre bore of face shield at newel, can be haled this newel among this valve block one end; Make face shield closely fix the cervical region between valve block and convex body; And difficult drop-off so just can be supplied sufferer and suck more purity oxygen, is its purpose person.Its practical effect is when unquestionable, and this creation is never made known publicly or be shown in other publication, the real regulation that has met Patent Law, hence propose in accordance with the law patent application it.
