Description

Technical Field

[0001] The present invention relates to the technical field of maternal and infant medical equipment, and in particular to a maternal and infant blood sampling and lactation device. Background Art

[0002] Breast milk is the juice produced by women's breasts after childbirth to feed babies. The nutrition of breast milk is natural and irreplaceable, and it is the best and indispensable source of natural immunity for babies. However, some mothers need to breastfeed after childbirth. In addition, blood sampling for infants and young children after childbirth is also a common sampling and inspection operation.

[0003] Most of the existing lactation needles have a simple structure and need to be manually operated based on the experience and judgment of medical staff. When dealing with different parturient women, the lactation effect is likely to be poor due to lack of experience. At the same time, the blood collection device for infants cannot be adjusted according to specific circumstances, has poor adaptability, and is prone to poor blood collection results.

[0004] Therefore, there is an urgent need for a maternal and infant blood sampling and lactation device to solve the above-mentioned problems. Summary of the invention
