Detailed description of the invention

The physiological structure of nose shows as the bridge of the nose moved towards up and down, forms nose in bridge of the nose lower end, and in the inner side of nose and nose, two nostrils are about symmetrical in nose, and meanwhile, two wings of nose are also about symmetrical in nose, and the maximum end of nose is wing of nose part.

Generally about 15 degree are become with horizontal plane, from face outwards obliquely on the downside of nose.

Ear upper limb is usually less than on the downside of nose.

Nostril form is not the circle of rule, neither be oval, and shape difference is relatively large, but generally shows as near facing side comparatively large, relatively little away from facing side.

See a kind of child's double-side-hole Oxygen tube shown in accompanying drawing 1-4, its basic structure comprises:

One matrix 3, be plates, material can be chosen as silica gel, also can be chosen as multiple structure, wherein, is chosen as such as silica gel with the layer of contact skin, and remainder layer selects plastics or other materials.

Matrix 3 entirety can show as the relatively soft material of employing and make, and plasticity is stronger, easily structure sealed engagement face, and easily mates the nose type of different people according to its elasticity.

When adopting multiple structure, such as layer of silica gel coordinates with other structure sheafs, layer of silica gel can be combined by chemical bond with other layer, biogum is such as adopted to bond, also mechanical closing component structure can be adopted to carry out sealed, securing member need not be depended on, by structure jaw arrangement to the combination of layer of silica gel and other layer.

Matrix 3 is regarded as plates but does not represent that it does not have thickness, there are two faces upwards vertical with the party in a thickness direction, or be normal direction with this direction two faces, a face is towards skin, specifically on the downside of nose, we are referred to as first surface, the face relative with this first surface we be referred to as second, thus form two base surfaces of flaky matrix.

Wherein, as shown in Figure 1, be formed with caulking groove 5 on the first face, this caulking groove 5 makes for being conducive to, triangularity substantially, and the limit be wherein positioned in figure is below arc-shaped side, the physiological structure of coupling people upper lip.

The position of matrix 3 residing for caulking groove 5 can adopt elasticity material relatively preferably, does not require that it has higher coefficient of elasticity, avoids the too much compressing wing of nose, it should be noted that the wing of nose of children's is very soft, can produce air-flow not smooth under compressing.

Due to the cooperation of the bottom land of caulking groove 5 and the lift effect of other parts, do not require that the cell wall of caulking groove 5 has very good coordinating with the wing of nose, nose, can be formed based on three limits and reliably locate, and non-tight.

As previously mentioned, the base shape of caulking groove 5 is trianglees, specifically isosceles triangle, then some finishings can be done for the physiological structure of this triangle map people, the drift angle of the isosceles triangle such as shown in Fig. 1 cuts circle, for the location of nose part, base adopts arcuate structure, the physiological structure of coupling people upper lip part.

Two waists also can make finishing, such as, mate dilator naris and divide and set out curve (coupling cell wall is curved surface).But comparatively speaking, as previously mentioned, too much finishing is not done to two waists herein, only for triangle polyester fibre, and non-tight, and also therefore, it is possible to evade the different problem of human physiological structure.

Use the bottom land of this caulking groove 5 in order to relative with on the downside of nose, be similar to holding on the downside of nose, fit in cell wall and the wing of nose and nose side, laminating here does not indicate the laminating without any gap, only for representing location.

In Fig. 1, the bottom land of caulking groove 5 is in its normal direction, and the namely thickness direction of matrix 3, has two locating holes, in order to mate two nostrils.

Then configure trachea to introduce oxygen, mating two locating holes and respectively have one, usual trachea and locating hole sealing-in, is generally by chemical bond, such as biogum bonding, also can be that trachea and matrix 3 are directly made as integrally.Recommendation chemical bond.

Wherein, one end of described trachea is passed from second and is positioned corresponding locating hole, trachea at the end face of this end between caulking groove 5 bottom land and first surface, too much the leaning out of restriction trachea, avoid long tracheal injury nasal mucosa, this part leant out is defined as and leans out head, body head 6 as shown in Figure 1.

And then configuration connector, connect two tracheas in side, second place (referred to as second side), thus can be formed in the power of tractive two trachea each other, independent explanation can be made to this structure below.

Also configure tighting device for support in addition, be furnished with two and point be located on the downside of matrix 3 two ends, one end coupling of this tighting device for support each is connected to the corresponding side of matrix 3, and the other end is tightened in order to be connected with trachea after corresponding to pick up the ears piece at trachea.

During use, allow caulking groove 5 be positioned on the downside of nose, utilize the left and right of caulking groove 5 to locate and make to lean out head aligning nostril, trachea is because ride on ear, form ear loop 1 as shown in Figure 1, ear loop 1 does not design separately, only represents that trachea hangs over hook part ear having self-assembling formation shown in figure.

Adopt omissive representation in Fig. 1 in addition, omit the main pipe 2 of opposite side, to express schematic structure more clearly, those skilled in the art is to be understood that.

Obviously, this illustrated ear loop 1 utilizing the deflection deformation of trachea self to produce has stronger practicality, can mate the head circumference that child is different.

When trachea hangs on ear, a natural holding power obliquely can be produced, the physiology inclined-plane just on the downside of coupling nose, produce location reliably, and this holding power can be utilized to form sealing, nature, coordinate the shape of caulking groove again, can be formed and seal more reliably.

Trachea will be connected in the air distribution system of hospital, and general air distribution system is positioned on the head of a bed metope of sick bed, and pipe arrangement pulls down in air distributing device, and trachea is wanted drop-downly to put in place, and therefore, ear loop 1 can self-assembling formation, but built on the sand.

Therefore, need to configure tighting device for support, can be sagging after ear after trachea is drop-down, by connecting trachea on the downside of ear, form two effects, one is allow the state of ear loop 1 be kept, another is then increase holding point, and caulking groove 5 better and on the downside of nose is fitted.

Should be noted that in addition, due to traction action, two tracheas can be made at matrix 3 place to produce the power to both sides deflection, and cause tracheal deviation, such as, pore 7 deflection in Fig. 1, therefore, when taking trachea as positioning element, needing coupling two tracheas, being interconnected by described connector, not only eliminate the problem of tracheal deviation, and make overall framework more stable.

In said structure, utilize the location of caulking groove 5 can ensure positional precision relatively reliably, sealing effectiveness is slightly poor, and the sealing mainly by contact surface realizes.

In some preferred embodiments, in the bottom land of described caulking groove 5, coupling leans out head and is provided with the nostril support ring 4 being centered around and leaning out a periphery, and allow nostril support ring be supported on nostril place, there is not nasal mucosa at naris position, simple support can not produce too large injury.

Strut produced power and can increase sealing effectiveness between composition surface, even if thus supporting surface area is less, also can play reasonable sealing function.

Nostril form the circle of non-critical, not more oval, through long-term research, determine that described nostril support ring 4 is for ellipsoidal structure, but do not represent that other structures can not use, ellipsoidal structure adopts at nostril support ring 4 that possess such as silica gel makes must resilience force, utilizes the metamorphosis of self and rebound effect can match the shape in nostril and form location and sealing reliably, and can adapt to the nostril of various trait.

The major axis of oval structure and minor axis should not have big difference, and the ratio of major axis and minor axis generally adopts 1.2:1 to be advisable, maximum can not more than 1.5:1.

Further, the height of nostril support ring 4 is consistent with the degree of depth of caulking groove 5, long and affect it and insert to limit nostril support ring 4, and avoids it directly to contact with nasal mucosa.

Preferably, the major axis of described nostril support ring 4 is downwardly towards outer incline, and the major axis of two nostril support rings 4 normally becomes splayed, and it is oval geometry major axis that major axis is here expressed as nostril support ring.

Here be outwards that proportion both sides are outward, in being with reference to position in nose in nose.

Further, in order to mate the physiological location in nostril, the axis leaning out head is positioned on the downside of major axis, and between nostril support ring 4 center and downside focus, nostril support ring 4 substantially can be made to be relatively uniform with the combination in nostril.

Preferably, described nostril support ring 4 is silica gel material, and matrix 3 at least first surface be silica gel material, caulking groove 5 part is also configured to silica gel material, and silica gel is soft, light, non-stimulated to children's's skin.

About described connector 13, can be pure connector, in some preferred embodiments, adopt a connection tube, in order to connect and to be communicated with two tracheas, form connectivity structure simultaneously, there is better adaptability, and connection tube be vertical with two tracheas.

In concrete use, child is often in without cognitive competence to the concern of periphery things, the situation of extruding trachea exists, when side, it closes extruding, opposite side trachea often makes connection, therefore, occurred by the situation can effectively avoiding side trachea to be extruded that arranges of communicating pipe.

Preferably, for convenience of adjusting according to concrete use object, described tighting device for support comprises and is fixed on the other end on matrix 3 is connected to lasso trick 10 on lasso 11 for being enclosed within lasso 11 on trachea and one end.Like this can be different according to the head circumference of such as child, type difference in face carries out the adjustment of lasso 11 in position of trachea, with the pulling force of the tension force and lasso trick 10 that adjust trachea, can directly adopt adhesive plaster to be bonded on trachea by lasso 11 after adjustment, keeps fixing.

In some embodiments, described lasso 11 is cushion rubber, and the circle body section of lasso 11 is rectangle, and the long limit of this rectangle is in the axis of lasso 11, and length-width ratio is 10:1, facilitates the adhesion of adhesive plaster on trachea.In addition, often there is between cushion rubber and trachea certain adhesion effect, after adjusting to the right place, often do not need extra article to adhere to, thus can free hand to the bonding operation carrying out adhesive plaster.

Frequent investigation finds, the length of described trachea is 1.5 ~ 2 meters and has better practicality, is for child, often needs household to accompany, take in one's arms it, and what this will certainly affect trachea walks pipe.This programme adopts relatively long trachea, and than conventional Oxygen tube extended length, family members or nursing staff embrace children's can certain activity space, fools the child cry and screamed the most applicable especially to bosom.

In some preferred embodiments, be provided with positioning convex 8 in the downside coupling people of described matrix 3, the location of matrix 3 can be carried out better.
