Wrist sphygmomanometer and blood pressure measurement method

The present invention relates to a wrist sphygmomanometer and a method of measuring blood pressure.

A typical wrist sphygmomanometer generally includes a main body and a wristband. The user can place the main unit on the wrist pulse and attach the wrist strap to the wrist. The measurement button or the power switch of the main body is activated, and the airbag in the wristband is inflated and pressurized to a predetermined air pressure value, and then the air in the airbag is started to be decompressed. The user's pulse and blood pressure are measured during the decompression process and displayed on the LCD screen of the host computer in a digital format for the user to read.

When using a wrist sphygmomanometer to measure blood pressure, it is generally recommended to lift the wrist of the fixed sphygmomanometer and make it the same height as the height of the heart, because a more accurate blood pressure value can be obtained. However, when the average user fixes the wrist sphygmomanometer to the wrist, the entire arm and wrist can move freely and rise, which tends to make the wrist sphygmomanometer unable to be high with the heart, so the measured blood pressure value is often not accurate enough.

In order to solve the problem of inaccurate blood pressure measurement caused by the aforementioned measurement position, US 6,872,182, EP1,647,222, EP1,254,629 and CN2001804954.0 The wrist sphygmomanometer disclosed in the patent can solve this problem, but it needs to include a biological information input device that can input the length of the forearm of the user and the length of the upper arm, and a posture detecting device for detecting the posture of the user. In particular, the user needs to measure information such as the length of his forearm and the length of the upper arm, and input it into the biological information input device one by one. In addition, the posture detecting device of the wrist sphygmomanometer needs to use a gravity acceleration sensor or an infrared transmitting and receiving device to obtain the position and angle of the user's forearm and upper arm. Finally, through complicated calculations, it is possible to know whether the wrist sphygmomanometer is high with the heart. Such a complicated wrist sphygmomanometer is not only time-consuming to use, but also requires multiple optical or mechanical sensors in the sphygmomanometer to capture the instantaneous information of the user's arm posture, and also causes an increase in the manufacturing cost of the sphygmomanometer. In addition, the Chinese patent CN2005101118712.4 also proposes a wrist sphygmomanometer of similar structure, and thus has the same disadvantages.

Chinese patent CN201180043220.7 proposes another invention of a wrist sphygmomanometer, which uses a microwave transmitting portion to illuminate a user's body with a microwave, and receives a reflected wave by a microwave receiving portion, thereby detecting a fixed wrist in the blood pressure measurement. The position of the wrist of the sphygmomanometer. The reflected wave is a reflected microwave that generates a Doppler shift due to the user's heartbeat. Therefore, expensive microwave components such as a microwave Doppler sensor and a microwave Doppler demodulator are required, and even complicated calculation is required. The process begins by knowing if the sphygmomanometer is at the same height as the heart.

Taiwan's new patent M445959 proposes a different wrist sphygmomanometer that uses a strap that can be placed over the neck to limit part of the movement of the wrist of a fixed wrist sphygmomanometer, and one end of the strap is fixed to the sphygmomanometer. Such a design Although the wrist sphygmomanometer has a simple structure, the wrist can still pull the belt up and down, so it is impossible to ensure that the wrist sphygmomanometer is at the same height as the heart.

In view of the problems encountered in the prior art described above, the present invention provides a wrist sphygmomanometer and a blood pressure measuring method which are not only easy to operate but also cost-effective, and more importantly, ensure that the wrist sphygmomanometer is flush with the heart.

The invention provides a wrist sphygmomanometer comprising a main body and a wristband. The main body has a top surface and a bottom surface. The host includes a measurement aid disposed on the side or top surface of the host. The measurement aid includes at least one viewing aperture and an alignment aid. At least one viewing aperture has at least one opening. The alignment aid is placed near the bottom surface. The opening of the viewing aperture to the alignment aid element defines a predetermined distance that is greater than the size of the opening. The wrist strap is combined with the bottom surface of the main body.

The invention further provides a blood pressure measuring method, which is characterized in that the wrist blood pressure meter is used for blood pressure measurement, and the measuring method comprises: fixing a wrist blood pressure monitor to a user's wrist and moving the forearm or the upper arm; seeing the pair through the observation hole a quasi-assist component; and initiates a blood pressure measurement of the host and reads the blood pressure value.
