Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a portable breastfeeding milking device. Background Art

[0002] A breast milk expression device simulates a baby's natural sucking action, creating negative pressure (suction) and appropriate massage stimulation to draw milk from the mammary glands and collect it in a container. This device is essential for breastfeeding mothers, especially those who work. Failure to express breast milk can lead to breast engorgement and pain, and in severe cases, blockage of the mammary glands, resulting in cessation of milk secretion.

[0003] Traditional breast milking devices, whether manual or electric, usually require lactating women to hold the device before they can perform the milking operation. A milking operation usually takes 10 to 20 minutes or even half an hour, and milking needs to be performed every few hours. For women who want to work, this is not only very uncomfortable to operate, but also a waste of time. Summary of the Invention

The horizontal sliding of the adjusting rod 44 can drive one end of the second connecting rod 43 to slide horizontally in the first limiting groove 22, thereby adjusting the height of the crossbeam 41. The change in the height of the crossbeam 41 drives the height of the bracket mechanism 5 to change. A clamping seat 613 is provided on one side of the three-way valve body 61, a clamping block 512 is fixedly provided on one side of the push rod 51, and a clamping holder 513 is fixedly provided below the clamping block 512. The clamping seat 613 can be clamped on the clamping block 512, and the bottleneck 621 can be clamped on the clamping holder 513, so that the milking mechanism 6 is clamped on one side of the push rod 51. The two bottom bars 52 can be moved to any position on the track 412, and the distance between the two bottom bars 52 can be adjusted arbitrarily. The two bottom bars 52 can be moved closer to or farther away from each other by stretching or compressing, thereby adjusting the distance between the two bottom bars 52. The third connecting bar 54 and the fourth connecting bar 55 can maintain the distance between the two bottom bars 52, that is, maintain the distance between the two top bars 51, thereby adjusting the distance between the two milking mechanisms 6. At the same time, after the front side of the push rod 51 is raised, the diagonal support rod 53 is inserted into different slots 523, so that the push rod 51 can be fixed to different pitch angles, thereby achieving the pitch angle adjustment of the milking mechanism 6. In conjunction with the height adjustment of the crossbeam 41 and the adjustment of the distance between the two push rods 51, it can adapt to different body shapes of lactating women; Then, the main unit 1 and the milking mechanism 6 are connected through the air guide tube 12. The lactating woman sits at the table and starts the main unit 1. The negative pressure pump in the main unit 1 drives the three-way valve body 61 through the air guide tube 12 to squeeze the milk into the milk bottle 62. After the milking operation is completed, the milk bottle 62 filled with milk is covered with a lid and sealed, the bottleneck 621 of the milk bottle 62 is clamped on the clamping tray 513, the push rod 51 is moved above the bottle holder 23, the height of the crossbeam 41 is adjusted, and the bottom of the milk bottle 62 is driven to clamp on the bottle holder 23, so that the milk bottle 62 can be fixed on the bottom plate assembly 2. At this time, the host 1 can power the refrigeration plate through the power cord, so that the milk bottle 62 can be refrigerated after milking. Then the dust cover 3 is covered above the crossbeam 41, and cooperates with the folding sealing curtain 21 to form a heat-insulating space, effectively extending the storage time of the milk in the milk bottle 62, providing convenience for women who feed their babies through the milk bottle 62 after milking. The three-way valve body 61 and the milk bottle 62 can be separately clamped on one side of the push rod 51, or the three-way valve body 61 and the milk bottle 62 can be clamped on one side of the push rod 51 at the same time, so that the milking mechanism 6 is easy to disassemble and clean after disassembly; The bracket mechanism 5 can be removed from the crossbeam 41. At this time, the bracket mechanism 5, the milking mechanism 6 and the main machine 1 can be used alone. The distance between the two milking mechanisms 6 and the pitch angle of the milking mechanism 6 can be adjusted by the bracket mechanism 5, which can facilitate breastfeeding women to perform lying milking operations and meet the different operating needs of breastfeeding women.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
