Description

Bionics feeding bottle with steady negative pressure

This utility model belongs to a kind of bottle-feeding device, the bionical feeding bottle of particularly a kind of stable negative-pressure type.

The crowd knows that healthy infant birth promptly began suckling after 12 hours.Normal breast suckling should be satisfied competent milk, the suitable continual and steady power of sucking, and this is not only the needs of infant physiological function, and the basic exercise that also is related to infant is taken exercise with healthy.Yet the puerperal that becomes a mother, it is imperative that artificial feeding promptly becomes when not possessing the suckling condition.Feeding bottle is the utensil that artificial feeding generally uses, and up to now, owing to the too simple reason of its structure, has obvious defects and inconvenience, so that influence the normal suckling and the health of infant always.Traditional totally enclosed type feeding bottle (its principle is shown in Fig. 1-first), increase along with sucking the milk that in the use, can cause a bottle interior negative pressure to strengthen, when air can't chew from milk the hole enter the bottle in the time, milk then can occur chews sunken and has to suspend suckling, could continue after the adjustment, the defective of such feeding bottle can cause infant physiology not accommodate operation inconvenience.Continue after, a kind of modified model feeding bottle (principle such as Fig. 1-second) appears, promptly make and keep atmospheric pressure state in the bottle by a fine duct that is in communication with the outside on the feeding bottle, such feeding bottle has overcome the interior defective that easily produces continuous value-added negative pressure of bottle of traditional feeding bottle, but new contradiction has appearred again simultaneously, need hardly when being the infant sucking milk is flowed out naturally under atmospheric pressure and action of gravity with the much power of sucking, make the sucking youngster " milk of choking " phenomenon often occur, so that easily cause the danger of aspiration pneumonitis, in addition because such feeding bottle exists and extraneous communication channel, so also there is the trouble of easily " leakage " to produce.

The purpose of this utility model is to provide a kind of stable negative-pressure type bionical feeding bottle, it can overcome the different shortcomings and inconvenience that above-mentioned feeding bottle exists, the feeding bottle that artificial suckling is used meets the mechanical characteristic of normal breast for milk more, thereby has guaranteed healthy development and the suck the breast needs of infant when artificial feeding.

The technical solution of the utility model: the bionical feeding bottle of a kind of stable negative-pressure type, comprise that nursing bottle body, screw cap and rubber milk chews, it is characterized in that milk chew interior and bottleneck between install one additional and stablize negative pressure device, this device is made up of mamillary passage, funnel stand, liquid check valve, passage disk and gas unidirectional valve; Said mamillary passage is a middle mamillary elastomer that leaves passage, said funnel stand is the funnel-form support, its big opening end has a positive stop lug boss, said liquid check valve is a circular piece, one concentric-ring pattern opening flap valve is arranged in the circular piece, this flap valve does not disconnect mutually with the outer ring sheet, said passage disk is a hollow stent, the one gridle edge that can insert funnel stand is arranged at its top, there is the hollow tubule that stretches out its underpart, the outer edge place of disk leaves the radial clearance groove, this clearance groove is connected with the hollow tubule of its underpart according to concentric grooves or shrinkage pool, is with the false blind head of an elastomeric material on the external end head of hollow tubule, and longitudinal cut is left in a promptly blind outer end; Above-mentioned mamillary passage is placed in the little opening of funnel stand, funnel stand is intercalated in the gridle edge on passage disk top, the liquid check valve of packing between funnel stand and the passage disk, the outer circumferential edge of this valve block is along being compressed by funnel stand, its concentric circular flap valve is in the spacing scope of the positive stop lug boss of funnel stand big opening end, and cover the hollow open of passage disk, the hollow tubule of the false blind head of the band of passage disk bottom, be that the gas unidirectional valve places in the feeding bottle, this disk places between bottleneck and milk chews, funnel stand and mamillary passage place milk to chew interior and chew inner face with milk and coincide, and its outside is screwed by screw cap.

Operation principle (see figure 7) of the present utility model: when feeding bottle handstand places in the sucking youngster mouth, because the sucking youngster sucks, make milk wash the flap valve of liquid check valve open and pass through funnel stand, mamillary passage and milk are chewed in mouthful inflow entrance, along with continuously outflowing of liquid, gas pressure intensity descends with liquid level and reduces to be small negative pressure state in the bottle, when difference reaches certain numerical value between the atmospheric pressure outside this negative pressure and the bottle, then the gas unidirectional valve of passage disk bottom (promptly being enclosed within the false blind head that leaves otch on the hollow tubule) is opened (seeing A place arrow) automatically and is made bottle outer air along clearance groove on the passage disk outer edge and the hollow tubule inflow bottle interior (seeing B place arrow) that is communicated with groove, during less than certain numerical value, air check valve is auto-closing again until the bottle inside and outside differential pressure.The pressure difference of above-mentioned said decision gas unidirectional opening of valves is relevant with the coefficient of elasticity of the false blind head of the elastomeric material that leaves otch.

Superiority of the present utility model is: 1, simple in structure, design liquid check valve and gas unidirectional valve and auxiliary device thereof cleverly, on the basis that does not change original tradition milk bottle structure, defective and inconvenience in the existing feeding bottle use have more ideally been overcome, shorten the distance between artificial feeding and mother's suckling, had good bionical effect; 2, use (comprising operation and cleaning) convenient; 3, can make separately, building block system is installed, and is with low cost, and the wide development prospect is arranged.

Below in conjunction with drawings and Examples further specify present technique,
