Description

Wrist type sphygmomanometer

Technical Field

The application belongs to the technical field of blood pressure measurement, and particularly relates to a wrist sphygmomanometer.

Background

Because blood pressure is an important index for measuring the health condition of a human body, the sphygmomanometer is a medical appliance which is commonly used in daily family stock and clinical medicine. Most of the existing home sphygmomanometers are wrist sphygmomanometers, and a common wrist sphygmomanometers generally includes a host and a wrist band. The user can place the host computer at the pulse position of the wrist and fix the wrist strap around the wrist. When the measuring button or the power switch of the host machine is started, the air bag in the wrist strap is inflated and pressurized to a preset air pressure value, and then the air in the air bag is released to reduce the pressure. The pulse and blood pressure of the user are measured in the decompression process and are displayed on a liquid crystal screen of the host in a digital form for the user to read.

In order to improve the measurement accuracy of the wrist type sphygmomanometer, a user is required to wear the sphygmomanometer on the wrist and place the sphygmomanometer at the same height with the heart during measurement. However, in the actual use process, it is difficult for users to ensure that the height is equal, and various methods are tried in the industry to solve the problem. For example, a user is reminded to keep the blood pressure meter at the same height as the heart through voice broadcast; the position change of the sphygmomanometer is detected through the acceleration sensor, so that the action that the user lifts the wrist is fuzzily recognized, and whether the user moves the sphygmomanometer to the position of the heart or not is judged. The voice broadcasting method only plays a role in reminding, and a user cannot identify the voice broadcasting method at all. For the method for detecting position changes, only the motion of a wrist raising is identified in a fuzzy way, and the position of the heart cannot be identified without accurate placement. Therefore, the existing schemes can not ensure the accuracy of blood pressure measurement, and the scheme for measuring the position change has higher implementation cost and is inconvenient for popularization of products.
