Description

Technical Field

[0001] The present invention relates to the technical field of prenatal care for pregnant women, in particular to a prenatal care device for pregnant women. Background Art

[0002] During pregnancy, especially in the third trimester, pregnant women's bodies undergo significant changes, including weight gain, increased pressure on the lower back, and poor blood circulation. These changes often cause pregnant women to feel uncomfortable in their daily lives, especially when sitting for long periods of time, which can easily lead to symptoms such as back pain and lower limb edema. Most existing maternity care devices have a single function and cannot meet the diverse needs of pregnant women at different stages. For example, traditional maternity chairs usually lack adjustable support structures and cannot be personalized according to the physical condition of the pregnant woman, resulting in insufficient comfort. In addition, existing care devices also have deficiencies in cushioning and breathability, and cannot effectively relieve the discomfort of pregnant women when sitting for long periods of time.

[0003] Therefore, we propose a prenatal care device for pregnant women. Summary of the Invention
