Description

Technical Field

[0001] The utility model relates to the technical field of blood pressure measurement, in particular to a blood pressure monitoring device during pregnancy. Background Art

[0002] Pregnancy-induced hypertension is a common pregnancy-specific disorder that can cause varying degrees of harm to the mother and fetus, even endangering their lives. Pregnancy-induced hypertension typically develops after 20 weeks of gestation and is characterized by hypertension, proteinuria, and other systemic dysfunction, with an incidence rate of 2.5% to 3%. To ensure the safety of both the mother and the fetus, pregnant women require long-term blood pressure monitoring to detect and intervene promptly.

[0003] Traditional blood pressure monitoring involves two methods: self-measurement at regular intervals daily, and monitoring with a fitness tracker. The former is cumbersome and difficult for pregnant women to perform independently, requiring assistance. The data also needs to be manually recorded for a doctor's assessment. The latter is simpler to use, but the accuracy of fitness trackers is poor, making them unsuitable for evaluation.

[0004] To sum up, traditional blood pressure monitors cannot automatically measure blood pressure, and each measurement requires manual operation and recording. For scenarios where long-term and regular blood pressure measurement is required, the operation is cumbersome, time-consuming, and labor-intensive, and it is not convenient for digital analysis. Although sports bracelets have a high degree of automation and digitization, the blood pressure data they measure is not accurate enough and can only be used for simple daily monitoring. The qualitative blood pressure data cannot be used for quantitative analysis in hospitals. Utility Model Content
