Description

Breast pumping device

Technical Field

The utility model relates to a breast-feeding auxiliary article, in particular to a breast-pumping device.

Background

The prior art breast pump 1, as shown in fig. 1, includes a cup 11, a suction conversion chamber 12, a secondary conversion chamber 13, an air tube 14, an electromagnetic valve 15, an air pump 16 and a feeding bottle 17. The suction generated by the air pump 16 reduces the space of the suction conversion cavity 12, so that the secondary conversion cavity 13 (through which milk flows) forms negative pressure to suck milk, and then the electromagnetic valve 15 discharges air to recover the volume of the suction conversion cavity 12, so that the milk flows into the feeding bottle 17 after the air pressure in the secondary conversion cavity 13 is equal to the external air pressure. Since the air intake and exhaust functions must be provided, two-stage conversion must be provided to eliminate the influence of exhaust on the pumping process, and thus, a relatively large number of fitting parts and a relatively large volume space are required to provide the functions, and noise is generated.

The utility model solves the technical problems in the prior art and provides a breast pumping device, which comprises a cover body and a suction unit, wherein the cover body is in a bowl shape, and a breast outlet is arranged in the central area of the cover body; the suction unit comprises a silicone tube and a one-way valve; one end of the silicone tube is an inlet, and the other end of the silicone tube is an outlet; the inlet is butted with the milk outlet; the one-way valve is disposed adjacent the outlet; the silicone tube is pressed to correspond to the opening of the one-way valve, the inlet is communicated with the outlet, the silicone tube is reset to correspond to the closing of the one-way valve, and the inlet is not communicated with the outlet.

Further improvements of the present invention are as follows.

And the outlet of the silicone tube is provided with a thread structure.

Comprises a milk storage bag; the bag opening of the milk storage bag can be connected to the outlet of the silicone tube.

The milk storage bag is a vacuum bag.

The silicone tube is a straight tube.

The silicone tube is a bent tube, and the included angle between the entering direction and the flowing direction is 0-90 degrees.

Compared with the prior art, the beneficial effects of the utility model are that: the breast pump has the advantages of exquisite structure, small volume, convenient operation and no noise.

Detailed Description

The present invention will be further described with reference to the following description and embodiments.

As shown in fig. 1 to 5, a breast pump device 2 comprises a housing 21 and a suction unit 22, the housing 21 having a bowl shape with a milk outlet 211 provided in a central region thereof; the suction unit 22 comprises a silicone tube 221 and a one-way valve 222; one end of the silicone tube 221 is an inlet, and the other end is an outlet; the inlet is butted with the milk outlet 211; a one-way valve 222 is disposed adjacent the outlet; the silicone tube 221 is pressed to correspond to the opening of the one-way valve 222, the inlet is communicated with the outlet, the silicone tube 221 is reset to correspond to the closing of the one-way valve 222, and the inlet is not communicated with the outlet. The breast pump device 2 of the present invention, in which the suction unit 22 is a power unit, is a key for generating negative pressure to suck milk. The working principle is as follows: the cover body 21 is attached to the mother breast and is in sealing contact with the breast, the nipple on the breast is aligned with the breast outlet 211, and when the silicone tube 221 is pressed and reset to reciprocate, negative pressure is formed inside the silicone tube 221 to suck breast milk. The pressure of the silicone tube 221 can be controlled to change the cavity variation and frequency of the silicone tube 221, so as to change the suction force and the milk sucking speed. When the breast is stimulated by the suction force, the milk is sucked out and flows out through the outlet of the silicone tube 221.

The outlet of the silicone tube 221 of the present invention is provided with a screw structure. Meanwhile, the breast pump device 2 of the utility model comprises a milk storage bag 23; the mouth 231 of the milk storage bag 23 can be connected to the outlet of the silicone tube 221. The breast milk thus discharged is collected by the milk storage bag 23.

The utility model discloses milk storage bag 23 is the vacuum bag for breast milk is in vacuum state relatively, can avoid the secondary to open, or with the air contact, thereby improves the quality of preserving of breast milk.

The utility model discloses silicone tube 221 can be a straight tube, as shown in fig. 2, also can be an elbow, and its entering direction is 0 degree to 90 degrees with the contained angle of outflow direction, as shown in fig. 5 to the parent uses.

The breast pump device 2 of the utility model has the advantages of exquisite structure, small volume, convenient operation and no noise.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
