Description

Technical Field

[0001] The present application relates to the technical field of breast milk collection, and in particular to a breast milk collector for gynecological care. Background Art

[0002] Breast milk is the most natural, safest and most complete natural food for infants. It contains all the nutrients and antibodies that infants need for growth. Sometimes, when mother and baby are separated for special reasons, breastfeeding is also necessary. Correct breastfeeding is increasingly valued and is crucial to improving nutrition and avoiding cross infection. Since breast milk collection is prone to contamination, which may lead to deterioration or affect the quality of breast milk, it is particularly important to collect breast milk correctly.

[0003] Using a breast milk collector can reliably collect excess milk, such as a multifunctional breast milk collector with publication number CN212282355U, which includes a milk collecting bottle, a tight pressure connection structure connected to the milk collecting bottle, and a functional component. The top of the milk collecting bottle is detachably connected to at least one functional head through the tight pressure connection structure. The tight pressure connection structure includes an inner screw sleeve, an outer screw sleeve, and an extension connector on the top of the milk collecting bottle and a sealing head provided on each functional head. The outer sleeve of the extension connector is connected to the outer sleeve and locked with each other. The sealing head of the functional head is detachably connected with the inner screw sleeve. The inner screw sleeve and the outer screw sleeve are threadedly connected to each other so that the end plane of the extension connector and the end plane of the sealing head are sealed and fitted with each other, and the functional head and the milk collecting bottle are tightly pressed and locked. The threaded connection between the inner screw sleeve and the outer screw sleeve adopts an interference thread connection; the functional head tightly pressed on the top of the milk collecting bottle is a milk suction cover, and the bottom of the milk collecting bottle is provided with a suction cup.

[0004] However, the above-mentioned prior art still has some defects when collecting breast milk: 1. The above-mentioned prior art ensures that the breast shield is sealed with the milk collecting bottle through a tight pressure connection structure, and utilizes the sealing performance of the tight pressure structure to completely prevent the entry of external air, so that the adsorption force and adsorption bearing capacity of the breast shield are stronger. However, during use, due to the different breast sizes between people, the adsorption force of the breast shield may be weakened.

[0005] 2. In the prior art, the index finger and thumb are used to squeeze the concave parts on the left and right side walls of the milk collecting bottle at the same time to separate them by vacuum negative pressure, so that the breast cup is adsorbed on the breast of the breastfeeding mother. However, this method of collecting breast milk cannot control the suction force when the breastfeeding mother is sucking milk. The suction force may be too small to suck out the breast milk, or too large to cause discomfort to the breastfeeding mother.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for collecting breast milk. Summary of the invention

A rotating ring 33 is rotatably installed on the outer side of the connecting ring 32, and a mounting groove 34 is opened inside the rotating ring 33. A mounting ring 35 is rotatably installed on the mounting groove 34. A plurality of limiting sliding holes 36 are uniformly opened on the side end of the connecting ring 32 in the circumferential direction. A sliding stopper 37 is slidably connected to the limiting sliding hole 36, and the sliding stopper 37 is tilted upward at one end facing the center of the connecting ring 32. The sliding stopper 37 is connected to the mounting ring 35 through a reset spring 38. The rotational connection between the ring 33 and the mounting ring 35 enables the return spring 38 to normally pop out the sliding block 37 when the rotating ring 33 rotates. An arc groove 39 is provided at the upper end of the mounting groove 34. A limiting slide post 310 is provided at the upper end of the sliding block 37, and the limiting slide post 310 slides in the arc groove 39. The sliding arrangement of the limiting slide post 310 in the arc groove 39 enables the sliding block 37 to slide in the limiting slide hole 36 when the rotating ring 33 is rotated.

The connecting plate 94 is connected to the inside of the breast shield 62 by a connecting spring 95, so that the pressure relief hole 91 remains in a closed state. Pressure relief grooves 96 are also uniformly opened on the side wall of the pressure relief column 92 in the circumferential direction to facilitate air exchange.

[0056] Before removing the breast shield 62, the air pressure inside the breast shield 62 is lower than the outside air pressure, and it is not easy to remove it. At this time, the pressure relief column 92 is pulled out through the pressure relief lifting plate 93, and the air outside the breast shield 62 enters the breast shield 62 through the pressure relief groove 96, so that the air pressure inside the breast shield 62 is consistent with that outside, so that the breast shield 62 can be removed. After the pressure relief lifting plate 93 is released, the pressure relief column 92 is reset under the action of the connecting spring 95.

[0057] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
