Abstract

The utility model relates to a spiral type negative pressure milk sucker, one end of a screw rod is fixedly connected with a piston at the inner cavity of a milk suction cylinder, wherein the outer diameter of the piston is anastomosed with the inner diameter of the milk suction cylinder, the other end of the screw rod is matched with a screw thread of the bottom of the milk suction cylinder, and the open mouth end of the milk suction cylinder is provided with a smooth convex edge. When the utility model is used, the open mouth end of the milk suction cylinder is buckled on a breast, a left hand supports the milk sucker, a right hand adjusts the movement of the screw rod, and a vacuum is formed. Negative pressure is gradually increased, milk is slowly sucked out, the suction force of the milk sucker is big, and operation is convenient.

Description

Spiral negative pressure breast pump

This utility model relates to medical apparatus and instruments, particularly the breast pump that uses between age of sucking of puerpera.

Breast pump is the essential product of puerpera between age of sucking, and its main uses is: 1, the milk that the baby is eaten up sucks out.The timely emptying of milk can promote galactopoiesis in reflexive ground.2, in the time of can not being baby's suckling at any time at breast distension milk and because of certain reason, available breast pump keeps the milk sucking-off so that continue to offer the baby.3, the milk in the breast should not accumulate overlong time, otherwise can cause bacterial infection, causes mastitis, uses breast pump can avoid pushing the bad habit of milk ejection, thereby prevents and reduce the generation of mastitis.In case 4, have mastitis to take place between age of sucking then must suspend suckling, and the most important treatment of mastitis is exactly in time to inhale empty milk, keep lactiferous ducts unobstructed, breast pump then is the instrument that can not be substituted so, breast pump still has the other purposes, as retracted nipple, cracked nipple person are arranged individually, is not suitable for or when suspending suckling, available breast pump sucking-off milk is used the soupspoon feeding infant.

Breast pump is women's indispensable articles for use between age of sucking, yet the breast pump that existing market is sold is all because of the too little sucking-off effectively of negative pressure milk, and as employed bell-jar breast pump for a long time, its negative pressure is that the rubber bulb by afterbody forms.Because of the restriction that is subjected to rubber bulb elasticity and capacity can't reach ideal negative pressure, even the milk about also can only sucking-off 10ml during the breast distension, suctorial type breast pump for another example, be that translucent cover is buckled in connection rubber tube in back on the breast, the strength of sucking rubber tube by the puerpera oral cavity forms negative pressure, and its negative pressure is also very little naturally.

The breast pump that provides a kind of suction big, easy to operate is provided the purpose of this utility model.

Technical solution of the present utility model is: spiral negative pressure breast pump comprises being buckled in supramammary container and negative pressure device that at the barrel cavity that sucks, an end of screw rod is fixedlyed connected with the piston that barrel internal diameter that sucks coincide with external diameter; The threaded engagement of the other end of screw rod and the drum head that sucks; Barrel opening end that sucks has slick convex edge.Screw-internal thread fit on the screw rod hole wall on the screw rod and the drum head that sucks, perhaps cooperate with the outer nut of drum head that sucks, pore is arranged on the drum head, screw rod has not been held spiro rod cap, suck the bucket opening end be equipped with the band papillary foramina leather cup, the elasticity apron left-hand thread on the leather cup is on barrel convex edge that sucks.

According to technique scheme, the puerpera is buckled in barrel opening end that sucks of breast pump on the breast, nipple exposes from the papillary foramina on the leather cup, puerpera's left hand is breast pump fixedly, the right hand is adjusting screw(rod) gently, and piston moves to the drum head that sucks, and air is discharged from the drum head pore, negative pressure is changed from small to big, with slowly sucking-off of milk.Leather cup shields to breast when forming negative pressure, avoids being inhaled length, sagging because of negative pressure makes mammary areola too greatly.Suck or when being filled milk, make air admission with have gentle hands by breast top, breast pump promptly is removed, and at last milk is poured out.The volume of evacuation can reach 250ml.

Accompanying drawing 1 is this utility model cross-sectional schematic;

Accompanying drawing 2 is for adopting this utility model signal of transparent material.

In conjunction with the accompanying drawings, embodiment of the present utility model is described.Spiral negative pressure breast pump comprises being buckled in supramammary container and negative pressure device, and at bucket 6 inner chambers that suck, an end of screw rod 5 is fixedlyed connected with the piston 4 that bucket 6 internal diameters that suck coincide with external diameter; The other end of screw rod 5 and the bucket threaded engagement at 6 ends that sucks; Bucket 6 opening ends that suck have slick convex edge 2.Piston 4 is a rubber stopper, with the clamping that is fixedly connected as of screw rod 5.Screw-internal thread fit on the screw rod hole wall on the screw rod 5 and bucket 6 drum head that suck perhaps cooperates with the nut 8 of bucket at 6 ends that suck, and has pore 7, screw rod 5 not to hold on the drum head spiro rod cap 9 is arranged.Opening end at the bucket 6 that sucks is equipped with the leather cup of being with papillary foramina 3, and elasticity apron 1 left-hand thread on the leather cup is on convex edge 2.Breast pump can adopt stainless steel material, for meeting puerpera's applied mental, preferably adopts transparent material, as glass, transparent plastic etc.
