Further, the pressure gauge is a common pointer pressure gauge, and the pressure gauge is in the prior art, and is not described herein in any more detail.

Furthermore, the inflating device is a needleless injector, the head of the injector is hermetically inserted into the third opening and detachably connected with the third opening, after the nipple and the pressure gauge are connected, a certain amount of gas is collected by using the injector, then the head of the injector is inserted into the third opening, and a certain amount of gas is injected into the three-way pipe, so that the nipple can be expanded, the hardness degree is moderate, and the injector is not drawn out during the sucking process of the premature infant; in addition, the piston of the injector cannot move in the sucking process of the premature infant, generally, the piston of the injector can be fixed by the friction force of the piston of the injector, and the piston of the injector can also be fixed by hand or by using a device, the fixing method is the prior art, and the fixing method is easy to think by a person skilled in the art and is not described herein in detail.

Furthermore, still be equipped with sealing valve in the third opening, set up sealing valve and can seal the third opening, only need open sealing valve aerify in the time of aerifing can, after the gas filling, close sealing valve and just can extract the syringe, sealing valve can provide better sealed effect, improves measurement accuracy.

The utility model has the advantages that: the utility model discloses can accurate measurement premature infant suck the negative pressure value, device simple structure, low in manufacturing cost is honest and clean, and the third opening of three-way pipe can fill into gas, can change the atmospheric pressure in the nipple, increases atmospheric pressure gradually, and then improves premature infant's sucking ability gradually.

The utility model can provide quantitative data of oral cavity negative pressure during sucking, and provide objective basis for evaluation of transition oral feeding; when sucking and pressure measuring, non-nutrition sucking training is synchronously carried out, the coordinated development of facial muscles, mandible, soft palate, tongue and the like is promoted, and finally good coordination of sucking, swallowing and breathing is realized.
