Description

Bionic baby nipple matched with breast pump

Technical Field

The utility model belongs to the technical field of milk suction, and particularly relates to a bionic baby nipple matched with a breast pump for use.

Background

As is known, when a lying-in woman gives birth to a baby, the lying-in woman cannot secrete milk in time, so that the baby cannot naturally and smoothly breast-feed, and needs to use a milk sucking tool to give milk in time; some puerpera have excessive sucking capacity relative to the baby after milk production, so that the breasts of the puerpera are distended and painful, and the excessive milk needs to be sucked out by a sucking tool.

At present, breast pumps on the market comprise electric breast pumps and manual breast pumps, and the basic principle of the breast pumps is that milk is sucked out in a negative pressure adsorption mode.

However, in the actual use process, the milk sucking nipple adopted by the prior milk sucking device is horn-shaped, and is abutted against the breast of a user from the horn opening part, and is communicated with the negative pressure cavity from the horn closing-in part, therefore, the sucked milk flows into the milk bottle from the horn closing-in part under the action of negative pressure, and meanwhile, in the milk sucking process, the cavity formed by the milk sucking nipple cannot be changed, so that the milk sucking nipple belongs to mechanical milk sucking, and further relative movement of the upper jaw and the lower jaw of a baby during milk sucking can not be simulated, so that the effects of massage and lactation promotion can not be achieved, and the puerpera can not be very uncomfortable and can feel painful when using the milk sucking nipple.

As shown in fig. 1, the bionic baby nipple used with a breast pump according to the present embodiment includes a trumpet-shaped milk sucking portion, and includes an inner plug 1 inserted into an inner cavity of the milk sucking portion, a plug sleeve 2 disposed at an outer end of the inner plug 1 and sleeved on an opening edge of the trumpet of the milk sucking portion, and a plug 3 disposed at an inner end of the inner plug 1.

In this embodiment, the sleeve 2, the inner plug 1 and the nozzle 3 are integrally formed, and are made of the same material, which is silica gel. The plug sleeve of the silica gel is arranged, so that the comfort level of contact with the skin is high; the inner plug body and the plug nozzle of the silica gel are arranged, so that the state that the baby sucks breast milk can be effectively simulated.

As shown in fig. 2, the end of the nozzle 3 remote from the inner plug 1 forms a flat milk outlet 30 a.

Referring to fig. 3 and 4, a milk sucking cavity 10 is formed inside the inner plug body 1, and the milk sucking cavity 10 is arranged to be smaller from the opening of the trumpet to the closing-in.

Specifically, the inner plug body 1 comprises a first plug body 11, a second plug body 12 and a third plug body 13 which are sequentially arranged from the horn opening to the closing-in.

The first plug body 11 is located between the sleeve 2 and the second plug body 12, and is formed to have a thickness gradually increasing from the flared opening to the mouth, in this example, the minimum thickness is d1, and the maximum thickness is d 4.

The second plug body 12 is provided with a wall thickness gradually decreasing from both end portions to a middle portion, and has a minimum thickness d 2.

The third plug body 13 extends from the end of the second plug body 12 to the end of the horn, and has the same thickness d 3.

In the example, d2 < d1 < d3 < d4, when the negative pressure sucks milk, the second plug body 12 deforms correspondingly from the thin wall, and the two opposite sides of the joint of the first plug body 11 and the second plug body 12 simulate the relative movement of the upper jaw and the lower jaw of the baby.

At the same time, the cross-sectional area of the milk outlet 30a is smaller than the cross-sectional area of the lumen of the third plug body 3. The nipple is mainly provided with a milk outlet with a small area, and the deformation of the second plug body can be ensured on the premise of meeting the requirement of negative pressure milk suction so as to realize the effect of the best bionic baby nipple.

The milk outlet 30a is flat, and the length of the long side corresponding to the flat shape is smaller than the inner diameter of the third plug body 13. In this way, the relative movement of the upper and lower jaws on opposite sides is facilitated.

The inside of the nozzle 3 forms a milk channel 30 which tapers from the inlet to the outlet and has a minimum wall thickness d5, where d2 < d 5. The deformation of the plug mouth is prevented from influencing the relative movement of the upper jaw and the lower jaw, and meanwhile, the milk is convenient to concentrate.

In particular, the maximum thickness of the stopper 3 is d6, where d6= d 3.

Meanwhile, the milk channel 30 is symmetrically arranged relative to the center of the long side, the longitudinal section of the milk channel 30 comprises a semicircular section a and a trapezoidal section b which are communicated, the diameter of the semicircular section a is equal to the inner diameter of the third plug body 13, the trapezoidal section b is communicated with the bottom surface of the semicircular section a from the upper bottom and forms a milk outlet 30a from the lower bottom, and the width of the upper bottom is greater than that of the lower bottom. The relative movement of the upper jaw and the lower jaw is realized optimally, and the dropping of milk is facilitated.

The plug sleeve 2 is covered on the edge 20 of the horn opening.

In this example, the flange 20 is connected to the end of the first plug body 11 remote from the second plug body 12. Therefore, the nipple is very convenient to disassemble, and the nipple is more beneficial to cleaning treatment.

Specifically, the wrapping 20 includes a first sheet 201 attached to an outer end surface (front surface) of a horn-shaped edge of the breast-sucking portion, and a second sheet 202 wrapped inward from an outer periphery of the first sheet 201.

In this example, the second blade 202 includes a first fold z1 that is attached to the circumferential side surface of the bell mouth edge, and a second fold z2 that is folded and wrapped from the first fold z1 toward the opposite surface (back surface) of the outer end surface of the bell mouth edge.

In summary, the present embodiment has the following advantages:

1. by changing different wall thicknesses of the inner plug body, the state that a baby sucks breast milk can be simulated when sucking milk under negative pressure, and the simulated upper jaw and lower jaw move relatively, so that the effects of massage and lactation promotion are achieved, and a parturient feels very comfortable and free of pain when using the nursing pad;

2. the plug sleeve is arranged, so that the bionic baby nipple and the breast pump can be conveniently disassembled and assembled, and the cleaning and the disinfection of the bionic baby nipple are further facilitated;

3. the arrangement of the milk channel and the milk outlet can optimally simulate the relative movement of the upper jaw and the lower jaw when a baby sucks the breast milk, further improve the milk sucking effect, and meanwhile, the sucked milk can quickly drip from the milk outlet;

4. the bionic baby nipple is made of silica gel, is integrally formed, is non-toxic and harmless, is convenient to clean, is comfortable in contact with skin, and is convenient to process and produce.

The present invention has been described in detail in order to enable those skilled in the art to understand the utility model and to practice it, and it is not intended to limit the scope of the utility model, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
