Description

Technical Field

[0001] This utility model relates to the field of blood pressure measurement technology, and more specifically, to a blood pressure measuring instrument host and a blood pressure measuring instrument. Background Technology

[0002] Blood pressure is one of the important physiological parameters for measuring a person's health status, and it is also an important standard for determining whether a person has hypertension.

[0003] With the improvement of people's living standards and the aging population, the incidence of hypertension is also on the rise. Compared with traditional mechanical blood pressure monitors, home electronic blood pressure monitors are simpler to operate and can be used by users at home, thus becoming increasingly popular.

[0004] The blood pressure monitor uses an air pump to inflate the cuff, compressing the arteries and completely occluding them. Then, the deflation valve is opened, allowing the pressure inside the cuff to slowly decrease. As the pressure decreases, the arteries undergo a process of complete occlusion, gradual opening, and then full opening. During this process, a pressure sensor collects the changing cuff pressure, converts it into a digital signal, and sends it to the CPU. Embedded software identifies the corresponding pressure points during the arterial blood flow obstruction and, based on accumulated software algorithms, calculates the diastolic, systolic, and mean blood pressure.

[0005] Existing electronic blood pressure monitors are generally used to measure blood pressure when the subject is sitting. However, some patients with hypertension only develop high blood pressure when lying down. In this case, doctors usually recommend a 24-hour blood pressure test, which generally requires a professional blood pressure monitor (ABPM) arranged by a doctor. However, professional blood pressure monitors (such as ambulatory blood pressure monitoring, ABPM) are professional instruments and are not suitable for home use. This makes it difficult for patients to detect their own lying hypertension early and miss the best treatment opportunity. Utility Model Content

The air outlet is located at the position corresponding to the connecting pipe 63, and a venting column 124 is installed on it. The interface of the connecting pipe 63 is sleeved on the venting column, thereby allowing airflow to flow between the main unit 100 and the cuff to realize the inflation and deflation functions. The clearance hole is located at the center of the bottom shell 12, and the probe of the pressure sensor 1 extends into the clearance hole, with at least a part of the probe protruding from the clearance hole.
