[0026] The utility model provides a breast shield 1.
[0027] In the embodiment of the present utility model, in combination with reference Figures 1 to 3 One side of the breast shield 1 is used to fit the breast, and the other side is formed with a milk suction channel 11 for placing the nipple. The end of the milk suction channel 11 away from the breast is provided with a milk outlet 12, and the milk outlet 12 is connected to a fixing seat 13, and the fixing seat 13 is used to install a milk collecting bag, and the milk collecting bag collects milk through the milk outlet 12; the fixing seat 13 is provided with an air vent 131, and the air vent 131 is connected to the inside of the milk collecting bag.
[0028] In this embodiment, the side of the breast shield 1 that fits the breast can be made of soft and skin-friendly materials, such as silicone or rubber, to improve the user's comfort. A milk suction channel 11 is formed on the other side of the breast shield 1, and the outer peripheral wall of the milk suction channel 11 can be made of hard materials, such as hard rubber or plastic. The milk suction channel 11 is tilted downward relative to the central axis of the breast shield 1, so that the milk flows directly from the milk outlet 12 under the action of its own gravity.
[0029] The breast shield 1 proposed in the technical solution of the utility model has one side for fitting the breast and the other side for forming a milk suction channel 11 for placing the nipple. A fixing seat 13 is provided at the milk outlet 12. The opening of the milk collecting bag can be sleeved on the outer peripheral wall of the fixing seat 13. A vent is provided on the fixing seat 13. The vent 131 is connected with the interior of the milk collecting bag. When the milk is sucked out from the breast, it flows into the milk collecting bag from the milk outlet 12 opened at the end of the milk suction channel 11 away from the breast, and the air in the milk collecting bag is discharged from the vent, so that the milk can flow into the milk collecting bag more smoothly from the milk suction channel 11. When the milk collecting bag is full, the filled milk collecting bag can be directly removed from the fixing seat 13, covered with a suitable lid, and directly frozen for storage to prevent secondary contamination of the milk.
[0030] In one embodiment of the present application, a ventilating gap 132 is provided between the fixing seat 13 and the milk collecting bag. The ventilating gap 132 is used to connect the vent hole 131 with the interior of the milk collecting bag, and the ventilating gap 132 can prevent milk from leaking out of the vent hole 131 .
[0031] In this embodiment, the fixing seat 13 is provided with an air hole 131. After installation, the one-way valve 14 and the fixing seat 13 have a narrow air permeable gap 132. After the fixing seat 13 is covered with a milk collecting bag, the air hole 131 is connected to the outside world, and the air hole 131 is connected to the air permeable gap 132, so as to ensure that the air output of the milk collecting bag through the air hole 131 is less than the air input through the milk inlet, so as to ensure that the milk collecting bag can be expanded by the gas entering the milk suction channel 11 during milk extraction, so as to facilitate the milk collecting bag to receive milk. At the same time, the small air permeable gap 132 can utilize the viscosity of milk while exhausting air, so as to ensure that milk will not overflow from the milk collecting bag opening when the user disassembles and installs the milk collecting bag upside down, that is, the milk collecting bag can be ventilated but not leaked.
[0032] In one embodiment of the present application, the ventilation gap 132 includes at least one ventilation groove, and the ventilation groove is in a strip shape.
[0033] In this embodiment, the ventilation gap 132 includes at least one strip-shaped ventilation groove, through which the air in the milk collecting bag can be discharged. The strip-shaped ventilation groove can increase the exhaust area, thereby increasing the exhaust speed and improving the milk collecting rate of the breast shield 1.
[0034] In one embodiment of the present application, the breast shield 1 further comprises a one-way valve 14, which is connected to the fixing seat 13 and communicates with the milk outlet 12; when in use, the one-way valve 14 is at least partially located in the milk collecting bag, and the air permeable gap 132 is provided between the fixing seat 13 and the one-way valve 14.
[0035] In this embodiment, the one-way valve 14 is arranged on the fixing seat 13 and is connected with the milk outlet 12. When negative pressure is applied, the one-way valve 14 is tightly attached to the milk outlet 12, and the milk will not flow back into the milk suction channel 11 from the milk storage component, thereby reducing the risk of milk contamination. When the negative pressure is stopped, the one-way valve 14 is away from the milk outlet 12, and the milk can flow from the milk outlet 12 into the milk storage container under the action of gravity and its own liquid pressure.
[0036] In one embodiment of the present application, the fixing seat 13 is provided with an inserting groove 133 , the one-way valve 14 is at least partially inserted into the inserting groove 133 , and the milk inlet end of the milk collecting bag is connected to the one-way valve 14 and the outside of the fixing seat 13 .
[0037] In this embodiment, a plug-in groove 133 is provided in the fixing seat 13, and the one-way valve 14 is inserted into the plug-in groove 133. The milk inlet end of the milk collecting bag is sleeved on the one-way valve 14 and the outer peripheral wall of the fixing seat 13. The milk flows into the milk collecting bag from the milk outlet 12 of the milk suction channel 11 and the one-way valve 14 to be collected and temporarily stored.
[0038] In an embodiment of the present application, the one-way valve 14 includes an inserting portion 141 and a valve plate 142 connected to the inserting portion 141 . At least a portion of the inserting portion 141 is inserted into the inserting groove 133 . The valve plate 142 is used to seal or open the milk outlet 12 .
[0039] In this embodiment, the plug-in portion 141 can be made of a material with an outer layer of soft rubber covering an inner layer of hard rubber, which can have a certain hardness and can be directly inserted into the plug-in slot 133, and can also prevent the one-way valve 14 from falling out of the plug-in slot 133 through the friction between the soft rubber and the plug-in slot 133. When the plug-in portion 141 is inserted into the plug-in slot 133, the valve plate 142 is attached to the edge of the milk outlet 12. When negative pressure is applied to the milk suction channel 11, the valve plate 142 of the one-way valve 14 can be adsorbed and tightly attached to the milk outlet 12, preventing the milk from being sucked back into the milk suction channel 11, causing secondary contamination of the milk.
[0040] In an embodiment of the present application, the insertion groove 133 extends along the axial direction of the milk suction channel 11 .
[0041] In this embodiment, the opening direction of the insertion groove 133 is the same as the axial direction of the milk suction channel 11, so that the insertion part 141 of the one-way valve 14 can be inserted into the insertion part 141 in a direction parallel to the milk suction channel 11, so that the valve plate 142 can better fit with the edge of the milk outlet 12, and negative pressure is applied in the milk suction channel 11. The valve plate 142 of the one-way valve 14 can be adsorbed and tightly attached to the milk outlet 12, preventing milk from being sucked back into the milk suction channel 11 and causing secondary contamination of the milk.
[0042] In one embodiment of the present application, a buckle 143 is provided on the one-way valve 14 , and a clamping groove 134 is formed on the side wall of the insertion groove 133 . The buckle 143 is used to be clamped in the clamping groove 134 .
[0043] In this embodiment, the one-way valve 14 and the fixing seat 13 are connected by a buckle 143, which improves the connection strength between the one-way valve 14 and the fixing seat 13, and prevents the one-way valve 14 from falling during use, causing the check function to fail. The buckle 143 is formed on one end of the one-way valve 14 inserted into the fixing seat 13, and a groove 134 is formed on one wall of the insertion groove 133 of the fixing seat 13. The buckle 143 can be connected to the groove 134 to prevent the one-way valve 14 from slipping out of the fixing seat 13.
[0044] In an embodiment of the present application, the fixing seat 13 is disposed at an upper end portion of the milk suction passage 11 .
[0045] In this embodiment, the fixing seat 13 is arranged at an upper position of the end of the milk suction channel 11. When the plug-in portion 141 of the one-way valve 14 is inserted into the fixing seat 13, the valve plate 142 just fits the edge of the milk outlet 12. The plane where the milk outlet 12 is located forms an angle with the vertical plane. The angle range is an acute angle, and the inclination direction from top to bottom is inclined away from the flange direction, so that milk can flow out of the milk outlet 12 of the milk suction channel 11 more smoothly.
[0046] The utility model also proposes a breast pump 100, comprising a breast shield 1, a negative pressure chamber 2, a suction component 3 and a shell 4. The breast shield 1 is the breast shield 1 described above; the negative pressure chamber 2 is used to provide negative pressure to the milk suction channel 11; the suction component 3 is arranged in the negative pressure chamber 2, and the suction component 3 can be deformed to apply negative pressure to the breast shield 1 and prevent milk from flowing to the negative pressure source; the shell 4 is connected to the breast shield 1 and encloses the breast shield 1 to form a accommodating cavity, and the accommodating cavity is used to accommodate a milk collection bag.
[0047] In this embodiment, the negative pressure chamber 2 is made of a non-deformable plastic material, a through hole is opened in a chamber wall of the negative pressure chamber 2 to communicate with the milk suction channel 11, the suction component 3 can be a diaphragm or a suction bowl, etc., the negative pressure source can indirectly apply negative pressure to the negative pressure cavity in the negative pressure chamber 2 through the diaphragm or the suction bowl, and then indirectly apply negative pressure to the milk suction channel 11, so that the milk can be sucked out of the breast, and the suction component 3 can prevent the milk from being sucked into the negative pressure source, causing the negative pressure source to short-circuit and fail or contaminate the milk. The shell 4 can be made of hard plastic material or light metal material, which is not further limited here.
