Description

Technical Field

[0001] The utility model belongs to the technical field of mother and baby products, and particularly relates to a cold and hot compress milk sucking device, and also relates to a breast pump. Background Art

[0002] A breast pump is an instrument for pregnant women to use after childbirth. During lactation, a mother can use the breast pump to suck out breast milk from the breast and store it. This not only facilitates the work and life of lactating women, but also effectively avoids the waste of breast milk. At the same time, it can also be used when the mother's nipple is damaged (such as chapped), and the baby cannot directly suck. Therefore, it is popular in the market.

[0003] At present, a conventional breast pump includes a breast pump assembly and a negative pressure source. The breast pump assembly includes a connecting part with a three-way connection, a breast shield, a milk bottle. The negative pressure source, the breast shield are respectively connected to the three interfaces of the three-way connection. When in use, the breast shield is pressed against the mother's breast, and then under the action of negative pressure, the milk is sucked out and drips into the milk bottle. However, in actual operation, there are the following difficulties:

[0004] 1) Once the mother has milk stasis but without redness, swelling or pain, hot compress is needed, which can accelerate blood circulation, help the breast relax and stimulate lactation, and at the same time make the breast softer, and then the milk can be squeezed out; on the contrary, when there is redness, swelling, pain or lumps, cold compress is needed to reduce the local temperature, reduce swelling, relieve pain, and control inflammation (severe cases may cause mastitis). However, ordinary breast pumps do not have the function of hot compress or cold compress at all, so they cannot meet the needs of use;

[0005] 2) Once the mother's nipple is damaged, due to the pulling and release of suction force during milk sucking with negative pressure, the nipple will be extremely pulled, resulting in pain during milk sucking. At the same time, during the extreme pulling process, even if a silicone soft pad is used, friction between the nipple and the silicone soft pad will still occur. Therefore, there is a probability of nipple damage and discomfort during milk sucking. If the nipple is already uncomfortable, the pain and damage will surely be aggravated. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a brand-new cold and hot compress milk sucking device.

[0007] At the same time, the utility model also relates to a breast pump.

[0008] To solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A cold and hot compress milk sucking device has a thermal conductivity of 1-2 W / m·K, and includes a nipple part with a milk channel, a fitting part that is flared outwards from the nipple part with an increasingly larger outer diameter, and an external connection part that is arcuately curved from the outside of the fitting part towards the nipple part. The nipple part forms a receiving space that matches the user's nipple. When in use, it is inserted into the breast shield of the breast pump from the nipple part so that the milk channel communicates with the milk sucking channel, and the external connection part is matched and docked with the flared opening of the breast shield.

[0010] Preferably, the cold and hot compress milk sucking device is integrally formed, and the inner wall surface is a smooth surface. Integral forming is convenient for processing, and at the same time, under the contact of the smooth surface, the probability of contact damage is reduced.

[0011] In some specific embodiments, the material of the cold and hot compress milk sucking device is ceramic or glass. The thermal conductivity of metal is too large, reaching 80 W / m·K, and the heat dissipation or heat absorption is too fast, while plastics are only about 0.2 W / m·K, which is not conducive to heat storage; neither of them is an ideal medium for cold and hot compresses; at the same time, the density of ceramic or glass is very high, and the friction coefficient of the smooth surface is very low, so it can effectively protect the nipples and areolas of new mothers, reduce tenderness, avoid pulling, and thus protect the damaged and edematous nipples to continue milk sucking.

[0012] According to a specific implementation and preferred aspect of the present invention, the nipple part includes a nipple body and a nipple head, and a plurality of milk channels are formed on the nipple head, and the nipple body is docked with the fitting part.

[0013] Preferably, the nipple head is spherical, and each of the milk channels extends along the radial direction of the sphere. Here, the extension direction is still relatively important because it determines the direction of milk extraction. If the milk is extracted in the same direction, there is a high probability of causing pulling or wrinkling and squeezing, resulting in discomfort during milk sucking, while the relative opening in multiple directions can enable the milk to be extracted from different angles, avoiding nipple wrinkling or squeezing and reducing the probability of discomfort during milk sucking.

[0014] Preferably, one of the plurality of milk channels is formed as a central through hole on the center line of the nipple, and the remaining plurality of milk channels are evenly spaced circumferentially around the central through hole. Generally, there is one through hole in the middle and a circle of through holes in the circumferential direction, with a total of 7-8. As for the aperture size, as long as the nipple is not pinched or squeezed during milk sucking.

[0015] According to another specific implementation and preferred aspect of the present invention, the length of the nipple body matches the length of the user's nipple, and the nipple fits against the inner wall of the receiving space. This can select a suitable model, avoid pulling during milk sucking, and meet the needs of different parturients.

[0016] Preferably, the material of the cold and hot compress milk sucking device is ceramic, and an extension frame body is formed on the outer periphery of the nipple head, and the end face of the nipple head is located inside the support surface formed by the extension frame body. The extension frame body mainly facilitates a relatively supported part during molding, for example, ceramic firing.

[0017] In addition, the outer connection part has a rounded corner transition and extends towards the nipple part to form a wrapping edge. In this way, the abutment is comfortable and it is also convenient for assembly.

[0018] Another technical solution of the present utility model is: a breast pump, which includes a breast pump assembly and a negative pressure source. The breast pump assembly includes a connecting part with a three-way connection, a breast shield, a milk bottle, the negative pressure source and the breast shield are respectively communicated with the three interfaces of the three-way connection, and the breast pump assembly further includes a cold and hot compress milk sucking device, and the cold and hot compress milk sucking device is disassembled and assembled on the breast shield.

[0019] Due to the implementation of the above technical solutions, the present utility model has the following advantages compared with the prior art:

[0020] When the existing breast pump is used for milk sucking, once the mother has milk stasis but no redness, swelling or pain, hot compress is needed, which can accelerate blood circulation, help the breast relax and stimulate lactation, and at the same time make the breast softer, and then squeeze out the milk; on the contrary, when there is redness, swelling, pain or lumps, cold compress is needed to reduce the local temperature, reduce swelling, relieve pain and control inflammation (in severe cases, it will cause mastitis). However, ordinary breast pumps do not have the function of hot compress or cold compress at all, so they cannot meet the usage needs; in addition, once the mother's nipple is damaged, due to the pulling and release of suction force during milk sucking by negative pressure, the nipple will be extremely pulled, causing pain during milk sucking. At the same time, during the extreme pulling process, even if a silicone soft pad is used, friction between the nipple and the silicone soft pad will be caused. Therefore, there is a probability of nipple damage and discomfort during milk sucking. If the nipple is already uncomfortable, it will inevitably exacerbate the pain and damage, etc. The present invention cleverly solves various deficiencies of the existing structure through the overall design of the cold and hot compress milk sucking device. After adopting this cold and hot compress milk sucking device, the cold and hot compress milk sucking device is cooled or heat-treated according to the working conditions, and then inserted into the breast shield of the breast pump from the nipple part so that the milk channel is communicated with the milk sucking channel, and the outer connection part is matched and docked with the bell mouth of the breast shield. During use, it is directly abutted against the mother's breast, the nipple is placed in the accommodating space, the cold and hot compress milk sucking device fits the breast, and finally milk sucking is carried out under cold compress or hot compress. Therefore, on the one hand, the cold and hot compress milk sucking device formed in cooperation with the breast pump based on the thermal conductivity coefficient can not only implement cold and hot compress during milk sucking, but also maintain the persistence of cold and hot compress; on the other hand, based on the formation of the accommodating space, it is avoided that the nipple during milk sucking is extremely pulled or generates movement friction, reducing the discomfort during milk sucking, especially when the nipple is damaged (such as chapped), reducing pain and further damage.

[0033] Embodiment 1

[0034] As Figures 1 to 4As shown, the cold and hot compress milk sucking device x3 involved in this embodiment has a thermal conductivity of 1 to 2 w / m.K, and includes a nipple part 1 having a milk channel 10, a fitting part 2 that is flared outwards from the nipple part 1 with an increasingly larger outer diameter, and an external connection part 3 that is arcuately bent from the outside of the fitting part 2 towards the nipple part 1. Among them, the nipple part 1 forms an accommodation space that matches the user's nipple. When in use, it is inserted into the milk sucking cover of the breast pump from the nipple part 1 so that the milk channel is communicated with the milk sucking channel, and the external connection part 3 is matched and docked with the flared opening of the milk sucking cover.

[0035] In some specific embodiments, the nipple part 1 includes a nipple body 1a and a nipple head 1b. Among them, a plurality of milk channels 10 are formed on the nipple head 1b, and the nipple body 1a is docked with the fitting part 2.

Among them, one of the plurality of milk channels 10 is located on the center line of the nipple to form a central through hole, and the remaining plurality of milk channels 10 are evenly spaced along the circumferential direction around the central through hole. Here, the extension direction is relatively important because it determines the direction of milk suction. If suction is in the same direction, there is a high probability of causing pulling or wrinkling and squeezing, resulting in discomfort during milk sucking. However, the relative opening in multiple directions can enable milk to be sucked out from different angles, avoiding nipple wrinkling or squeezing and reducing the probability of discomfort during milk sucking. Generally, there is one through hole in the middle and a circle of through holes are formed in the circumferential direction, with a total of 7 to 8. As for the aperture size, as long as the nipple is not pinched or squeezed during milk sucking.

[0037] In some specific embodiments, the cold and hot compress milk sucking device x3 is integrally formed, and the inner wall surface is a smooth surface. At the same time, the material of the cold and hot compress milk sucking device x3 is ceramic (of course, glass is also possible). However, for the convenience of ceramic firing, an extension frame 1c is formed on the outer periphery of the nipple head 1b, and the end surface of the nipple head 1b is located inside the support surface formed by the extension frame 1c.

[0038] In addition, the external connection part 3 has a rounded transition and extends towards the nipple part 1 to form a wrap-around edge.

[0039] Specifically, first, heat or refrigerate the cold and hot compress milk sucking device x3 according to the usage requirements, then install the cold and hot compress milk sucking device x3 on the milk sucking cover, and then bring the cold and hot compress milk sucking device x3 into contact with the mother's breast. Place the nipple in the accommodation space, and the fitting part 2 fits against the breast, so as to suck milk under the required cold compress or hot compress working conditions.

The thermal conductivity coefficient of metal is too large, reaching 80w / m.K, and the heat dissipation or heat absorption is too fast, while plastics are only about 0.2w / m.K, which is not conducive to heat storage; neither of them is an ideal medium for cold / hot compress; at the same time, the density of ceramic or glass is very high, and the friction coefficient of the smooth surface is very low, so it can effectively protect the mother's nipple and areola, reduce tenderness, avoid pulling, and thus protect the damaged and swollen nipple to continue sucking milk; on the fifth hand, each of the milk channels extends along the radial direction of the spherical surface. Here, the extension direction is relatively important because it determines the direction of milk extraction. If milk is extracted in the same direction, there is a high probability of causing pulling or wrinkling and squeezing, resulting in discomfort during milk suction. The relative opening in multiple directions can enable milk to be extracted from different angles, avoid nipple wrinkling or squeezing, reduce the probability of discomfort during milk suction. Generally, there is one through hole in the middle and a circle of through holes are formed in the circumferential direction, with a total of 7 to 8. As for the aperture size, as long as the nipple is not pinched or squeezed during milk suction; on the sixth hand, the length of the nipple body matches the length of the user's nipple, and the nipple fits the inner wall of the accommodation space, so that a suitable model can be selected to avoid pulling during milk suction and meet the needs of different parturients; on the seventh hand, the outer extension frame body is mainly to facilitate a relatively supporting part during molding, for example: ceramic firing; on the eighth hand, the external connection part has a rounded transition and extends towards the nipple part to form a wrap-around edge, so that the contact is comfortable and it is also convenient for assembly.
