Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to a breast pump and a breast shield thereof. Background Art

[0002] The applicant disclosed a self-adhesive breast pumping device in Chinese utility model patent publication number CN118787802A, which includes a one-way valve, a self-adhesive cover, a negative pressure generating unit, and a feeding bottle. The negative pressure generating unit has a negative pressure chamber, a gas exchange channel, a milk suction chamber, an assembly opening, and a milk discharge channel. The gas exchange channel is connected to the negative pressure chamber, and the assembly opening and the milk discharge channel are respectively connected to the milk suction chamber. The milk suction chamber and the negative pressure chamber are separated by a deformable component of the negative pressure generating unit. The self-adhesive cover is mounted on the assembly opening of the negative pressure generating unit. The one-way valve is provided on the negative pressure generating unit to selectively open and close the milk discharge channel. The feeding bottle is mounted on the negative pressure generating unit and covers the one-way valve. The self-adhesive cover includes a horn cover body with a movable space between the horn cover body and the negative pressure generating unit. The movable space enables the horn cover body to cover a portion of the breast after being turned over and restored, thereby allowing the self-adhesive breast pumping device to be reliably attached to the breast. During the milking process, as milk production increases, the weight of the self-adhesive breast pump increases. The active space can cause the bell housing to deform, causing the nipple to lose balance within the milking cavity of the negative pressure generating unit. After the milk is extracted, its direction of ejection relative to the negative pressure generating unit is altered, causing the milk to first be ejected onto the walls of the milking cavity and then reflected between the bell housing and the areola, rather than entering the milk discharge channel of the negative pressure generating unit. This can lead to milk leakage, which not only affects the milking effect but also the suction performance. Furthermore, the deformation of the self-adhesive housing caused by the active space can also affect the suction performance of the bell housing and the breast. Utility Model Content

[0038] With reference to the accompanying drawings of the present utility model Figures 1 to 4 A breast pump according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the breast pump includes a milk pumping device 10 and a breast shield 20 mounted on the milk pumping device 10.

[0039] Specifically, the breast shield 20 includes a self-adhesive shield 21 and a support portion 22, wherein the support portion 22 is protrudingly provided on the outer wall of the self-adhesive shield 21. Preferably, the self-adhesive shield 21 and the support portion 22 are integrally formed, for example, by injection molding of silicone material. The self-adsorption cover 21 can be installed on the milk suction device 10. After the self-adsorption cover 21 is installed on the milk suction device 10, an activity space 100 is formed between the self-adsorption cover 21 and the milk suction device 10. The support part 22 is located in the activity space 100 and can be against the milk suction device 10. The lower side of the self-adsorption cover 21 and the milk suction device 10 are supported by the support part 22. In this way, during the milk suction process, the milk suction device 10 will not fall with the increase of its own weight, causing the nipple to lose balance in the milk suction cavity 101 of the milk suction device 10, thereby preventing milk leakage and ensuring the adsorption of the breast shield 20, so that the breast pump is reliably adsorbed on the breast.

[0040] In addition, it can be understood that the support portion 22 supports the self-adhesive shield 21 and the breast pump device 10 on the lower side of the self-adhesive shield 21, so that the deformation amplitude of the breast shield 20 can be greatly reduced to ensure the adsorption of the breast shield 20 and the breast, so that the breast pump can be reliably adsorbed on the breast.

[0041] It is worth mentioning that in one example of the breast pump of the present invention, after the self-adhesive cover 21 is installed on the milk suction device 10, the support portion 22 can directly abut against the milk suction device 10. In another example of the breast pump of the present invention, after the self-adhesive cover 21 is installed on the milk suction device 10, a gap can be provided between the support portion 22 and the milk suction device 10. When the user uses the breast pump to express milk, the self-adhesive cover 21 can be slightly deformed, and the support portion 22 can abut against the milk suction device 10, thereby supporting the lower side of the self-adhesive cover 21 and the milk suction device 10.

[0042] Continue to refer to the attached Figures 1 to 4 The breast pump device 10 further has a milk discharge passage 102 and an assembly opening 103, both of which are connected to the milk suction chamber 101, wherein the self-adhesive cap 21 is installed on the breast pump device 10 at the position of the assembly opening 103. When a user uses the breast pump to express milk, the self-adhesive cap 21 can be self-adhesive to the breast, and the nipple is inserted into the milk suction chamber 101 of the breast pump device 10. As the pressure in the milk suction chamber 101 of the breast pump device 10 changes rhythmically, milk is sucked in and can be discharged from the milk suction chamber 101 through the milk discharge passage 102 of the breast pump device 10. Since the support portion 22 supports the self-adsorption cup 21 and the breast pump device 10 at the lower side of the self-adsorption cup 21, the relative positions of the nipple and the breast pump device 10 can be kept stable during the entire milk pumping process, thereby preventing the nipple from losing balance in the milk suction cavity 101 of the milk pump device 10, thereby preventing milk leakage and ensuring the adsorption performance of the breast cup 20, so that the breast pump can be reliably adsorbed on the breast.

[0043] Specifically, the milking device 10 includes a three-way component 11, a deformable negative pressure generating portion 12, a shell 13, a one-way valve 14 and a milk bottle 15, wherein the three-way component 11 has a front opening 111, a rear opening 112 and a bottom opening 113, the front opening 111 of the three-way component 11 forms the assembly opening 103 of the milking device 10, and the bottom opening 113 of the three-way component 11 forms the milk discharge channel 102 of the milking device 10, wherein the shell 13 is mounted on the three-way component 11, and the negative pressure generating portion 12 is clamped on the three-way component The milk suction device 10 is provided with a milk suction chamber 101 between the rear portion of the three-way component 11 and the housing 13, and the negative pressure forming portion 12 closes the rear opening 112 of the three-way component 11. In this way, the milk suction chamber 101 is formed between the three-way component 11 and the negative pressure forming portion 12. When the negative pressure forming portion 12 is deformed, the negative pressure in the milk suction chamber 101 changes. The one-way valve 14 and the milk bottle 15 are respectively installed at the bottom of the three-way component 11, and the one-way valve 14 selectively opens and closes the bottom opening 113 of the three-way component 11, and the milk bottle 15 covers the one-way valve 14. Specifically, when the negative pressure in the milk suction chamber 101 of the milk suction device 10 increases, the one-way valve 14 closes the bottom opening 113 of the three-way component 11, that is, the milk discharge channel 102 of the milk suction device 10 is closed. Correspondingly, when the negative pressure in the milk suction chamber 101 of the milk suction device 10 decreases, the one-way valve 14 opens the bottom opening 113 of the three-way component 11, that is, the milk discharge channel 102 of the milk suction device 10 is opened.

[0044] Furthermore, the top of the housing 13 is rotatably mounted on the upper side of the tee component 11 at the rear of the tee component 11, and the bottom of the housing 13 is detachably mounted on the lower side of the tee component 11 at the rear of the tee component 11. After the bottom of the housing 13 is separated from the lower side of the tee component 11, the housing 13 can be flipped over so that the negative pressure generating portion 12 can be removed for easy cleaning. After the bottom of the housing 13 is mounted on the lower side of the tee component 11, the tee component 11 and the housing 13 clamp the negative pressure generating portion 12, so that the negative pressure generating portion 12 closes the rear opening 112 of the tee component 11, allowing the milk suction device 10 to form the milk suction chamber 101 between the tee component 11 and the negative pressure generating portion 12.

[0045] It is worth mentioning that the specific structure in which the bottom of the housing 13 and the lower side of the three-way component 11 are detachably mounted is not limited in the breast pump of the present invention. Figures 1 to 4In this specific example of the breast pump of the present invention, opposite sides of the bottom of the shell 13 are provided with a buckle 131, and opposite sides of the lower side of the three-way component 11 are provided with a slot 114, respectively. The two buckles 131 of the shell 13 can be respectively snapped into the two slots 114 of the three-way component 11, wherein when the two buckles 131 of the shell 13 are respectively snapped into the two slots 114 of the three-way component 11, the bottom of the shell 13 and the lower side of the three-way component 11 are installed, and when the two buckles 131 of the shell 13 are respectively detached from the two slots 114 of the three-way component 11, the bottom of the shell 13 and the lower side of the three-way component 11 are separated.

[0046] Preferably, the negative pressure forming portion 12 has an annular groove 121, and the rear portion of the tee component 11 is inserted into the annular groove 121 of the negative pressure forming portion 12. In this way, when the bottom of the housing 13 is mounted on the lower side of the tee component 11 and the negative pressure forming portion 12 is clamped between the housing 13 and the tee component 11, the negative pressure forming portion 12 can reliably seal the rear opening 112 of the tee component 11. In addition, when the negative pressure forming portion 12 is installed between the tee component 11 and the housing 13, after the rear portion of the tee component 11 is inserted into the annular groove 121 of the negative pressure forming portion 12, the negative pressure forming portion 12 can be pre-installed on the tee component 11, so that when the housing 13 is turned over and the bottom of the housing 13 is allowed to be installed on the lower side of the tee component 11, the negative pressure forming portion 12 can be automatically clamped between the tee component 11 and the housing 13.

[0047] Continue to refer to the attached Figures 1 to 4The self-absorbing cover 21 of the breast shield 20 further includes a shoulder ring 211, a mounting ring 212, and a deformable horn cover 213. The mounting ring 212 extends toward one side from the inner edge of the shoulder ring 211, and the horn cover 213 extends toward the opposite direction from the outer edge of the shoulder ring 211. The support portion 22 is provided at the connection between the shoulder ring 211 and the horn cover 213. The assembly ring 212 of the self-adhesive cup 21 can extend through the front opening 111 of the three-way component 11 to the interior of the three-way component 11, so that the self-adhesive cup 21 is installed on the breast pumping device 10 at the position of the assembly opening 103 of the breast pumping device 10, and the support portion 22 supports the self-adhesive cup 21 and the breast pumping device 10 on the lower side of the self-adhesive cup 21. In this way, the deformation amplitude of the breast pumping cup 20 can be greatly reduced to ensure the adsorption of the breast pumping cup 20 and the breast, so that the breast pump can be reliably adsorbed on the breast. Optionally, in other examples of the breast pump of the present invention, the support portion 22 can be provided on the shoulder ring 211 of the self-adhesive cup 21.

[0048] Preferably, refer to the attached Figure 4 The support portion 22 is annular and surrounds the shoulder ring 211 of the self-adhesive cup 21. Thus, the support portion 22 acts as a framework to maintain the shape of the breast shield 20, reduce the deformation of the breast shield 20, and ensure the adhesion between the breast shield 20 and the breast. That is, by configuring the support portion 22 to be circular, on the one hand, the support portion 22 can support the self-adhesive cup 21 and the milk pump 10 at the bottom side of the self-adhesive cup 21, so that during milk pumping, the milk pump 10 does not fall due to its own weight, causing the nipple to lose balance within the milk suction chamber 101 of the milk pump 10, thereby preventing milk leakage and ensuring the adhesion of the breast shield 20 and the breast pump to the breast. On the other hand, the support portion 22 itself can maintain the shape of the breast shield 20, reduce the deformation of the breast shield 20, and ensure the adhesion between the breast shield 20 and the breast.

[0049] Continue to refer to the attached Figures 1 to 4The self-adsorption cover 21 includes a blocking portion 214, and the blocking portion 214 further includes a mounting ring 2141 and a deformable blocking ring 2142, wherein the blocking ring 2142 extends inward from one end of the mounting ring 2141, wherein the mounting ring 2141 is mounted on the assembly ring body 212, for example, based on the friction generated between the mounting ring 2141 and the assembly ring body 212, the mounting ring 2141 can be mounted on the assembly ring body 212, the blocking ring 2142 is maintained at the connection position between the shoulder ring body 211 and the assembly ring body 212, and the blocking ring 2142 extends inward at the connection position between the shoulder ring body 211 and the assembly ring body 212. When a user uses the breast pump to express milk, the nipple extends into the milk suction chamber 101 of the milk suction device 10 through the central through hole of the blocking ring 2142 of the blocking portion 214, and the areola is blocked by the blocking ring 2142. When the space of the milk suction chamber 101 of the milk suction device 10 is reduced, resulting in an increase in the negative pressure in the milk suction chamber 101, the nipple is pulled toward the milk suction chamber 101 of the milk suction device 10, and the areola is squeezed due to being blocked by the blocking ring 2142, so that the milk is squeezed out and temporarily stored in the milk suction chamber 101 of the milk suction device 10. When the space of the milk suction chamber 101 of the milk suction device 10 is increased, resulting in a decrease in the negative pressure in the milk suction chamber 101, the one-way valve 14 opens the milk discharge channel 102 of the milk suction device 10 to allow the milk to be discharged into the feeding bottle 15. That is to say, the blocking ring 2142 of the blocking portion 214 of the breast pump of the present invention can squeeze out milk, thereby improving the comfort and milk suction efficiency of the user when using the breast pump to suck milk, and because the blocking ring 2142 is deformable, when the nipple is pulled toward the milk suction cavity 101 of the milk suction device 10, the blocking ring 2142 will be deformed toward the milk suction cavity 101 of the milk suction device 10 while blocking the areola, that is, the blocking ring 2142 provides flexible blocking, thereby improving the comfort of the user when using the breast pump to suck milk.

[0050] Preferably, the end of the blocking ring 2142 extends in a curved manner toward the milk suction chamber 101 of the milk suction device 10, so that the breast shield 20 can prevent the nipple from contacting the end of the blocking ring 2142, thereby protecting the nipple.

[0051] Optionally, in the attached Figure 5In this specific example of the breast pump of the present invention, the blocking ring 2142 may integrally extend inward from the connection between the shoulder ring 211 and the mounting ring 212. In other words, the self-absorbing cover 21 and the support portion 22 of the breast shield 20 are an integrated structure. For example, the integrated breast shield 20 may be formed from silicone material through an injection molding process.

[0052] Attachment Figure 6 A modified example of the breast pump according to the present invention is shown. Figures 1 to 4 The breast pump shown is different in that Figure 6 In this specific example of the breast pump shown, the support portion 22 is provided on the milk suction device 10. When the self-adhesive cover 21 is installed on the milk suction device 10 and the activity space 100 is formed between the self-adhesive cover 21 and the milk suction device 10, the support portion 22 supports the self-adhesive cover 21 at the lower side of the self-adhesive cover 21. Therefore, during the milk suction process, the milk suction device 10 will not fall with the increase of its own weight, causing the nipple to lose balance in the milk suction cavity 101 of the milk suction device 10, thereby preventing milk leakage and ensuring the adsorption of the breast shield 20 and the reliable adsorption of the breast pump on the breast.

[0053] Attachment Figure 7 A modified example of the breast pump according to the present invention is shown. Figures 1 to 4 The breast pump shown is different in that Figure 7 In this specific example of the breast pump shown, the breast shield 20 further includes a closing portion 23, which is arranged at the periphery of the self-adsorbing shield 21 at the external opening of the self-adsorbing shield 21, and the thickness of the closing portion 23 is greater than the thickness of the periphery of the self-adsorbing shield 21 at the external opening. In this way, on the one hand, the closing portion 23 can prevent the self-adsorbing shield 21 from breaking due to its thin periphery at the external opening. On the other hand, the closing portion 23 can increase the strength of the periphery of the self-adsorbing shield 21 at the external opening, which is conducive to maintaining the peripheral shape of the self-adsorbing shield 21 at the external opening, so that the self-adsorbing shield 21 can be reliably adsorbed on the breast.

[0054] Attachment Figure 8 A modified example of the breast pump according to the present invention is shown. Figures 1 to 4 The breast pump shown is different in that Figure 8In this specific example of the breast pump, the self-adhesive cup 21 includes a mounting ring 212 and a flared cup 213. The mounting ring 212 extends rearward from the flared cup 213 and is used to attach the self-adhesive cup 21 to the breast pump 10. The curvature of the inner wall of the lower side of the flared cup 213 is greater than the curvature of the inner wall of the upper side. This allows the shape of the flared cup 213 to match the shape of the breast, facilitating reliable attachment of the breast shield 20 to the breast.

[0055] In addition, in the attached Figure 8 In this specific example of the breast pump shown, after the self-adhesive cover 21 is installed on the milk suction device 10, the activity space 100 is formed between the horn cover body 213 of the self-adhesive cover 21 and the milk suction device 10, and the support part 22 is protrudingly provided on the horn cover body 213, and the support part 22 supports the self-adhesive cover 21 on the lower side of the self-adhesive cover 21, so that during the milk suction process, the milk suction device 10 will not fall with the increase of its own weight, causing the nipple to lose balance in the milk suction cavity 101 of the milk suction device 10, thereby preventing milk leakage and ensuring the adsorption of the breast shield 20 and the reliable adsorption of the breast pump on the breast.

[0056] With attached Figure 7 The breast pump shown is similar in that Figure 8 In this specific example of the breast pump shown, the breast shield 20 includes the closing portion 23, which is arranged at the periphery of the self-adsorbing shield 21 at the external opening of the self-adsorbing shield 21, and the thickness of the closing portion 23 is greater than the thickness of the periphery of the self-adsorbing shield 21 at the external opening, that is, the closing portion 23 is arranged at the periphery of the trumpet cover body 213 facing away from the assembly ring body 212, and the thickness of the closing portion 23 is greater than the thickness of the periphery of the trumpet cover body 213 facing away from the assembly ring body 212. In this way, the closing portion 23 can prevent the trumpet cover body 213 from breaking due to its thin periphery thickness.
