Patch type non-pressure pulse blood pressure measuring device

A blood pressure measuring device, in particular, a patch type non-pressure pulse blood pressure measuring device.

According to the sphygmomanometer used in the market, it is mainly divided into a manual pump sphygmomanometer, a listening sphygmomanometer, and an Oscillation blood pressure. Among them, the manual pump type sphygmomanometer is most widely used. When measuring blood pressure, an arm band containing an air bag is wound around the upper arm of the test subject, and the operator manually presses a pump to make the pump Air is supplied to the balloon to inflate and pressurize the upper arm, and when the balloon is inflated to compress the upper arm artery of the subject, temporarily restricting blood flow through the upper arm artery. Then, the operator opens a deflation valve in communication with the arm band, and gradually reduces the pressure in the arm band. When the air bag pressure is lower than the pressure generated by the upper arm artery being blocked, the blood in the upper arm artery is from the arm band. The compression position is ejected to form a vortex, and at the same time, a sound wave commonly known as Krotkoff is emitted. At this time, the first K sound heard by the operator by a stethoscope, and the pressure on the corresponding mercury thermometer is the so-called systolic pressure. Thereafter, during the pressure relief of the airbag, the operator can continuously hear the K sound until the last K sound is heard, and the pressure measured on the mercury pressure gauge is the so-called diastolic pressure. The listening sphygmomanometer is also implemented in the same concept. The amplitude of a pulse obtained by measuring the test subject is converted into a voltage signal, and the voltage signal is compared with a voltage reference. Assume the voltage reference line At 0.5 volt (V), when the voltage value of the voltage signal converted from the amplitude of the pulse wave is greater than 0.5 volt, the listening sphygmomanometer emits a sound like a K sound (such as a voice), and is obtained by prompting the sound. The diastolic pressure and the systolic pressure. On the other hand, the oscillating sphygmomanometer calculates the diastolic pressure and the systolic blood pressure by looking for a large amplitude value in the pulse wave amplitude and confirming the pressure values corresponding to 0.5 Amax and 0.8 Amax.

However, the manual pump sphygmomanometer described above cannot be easily and arbitrarily operated, and it is still necessary to operate through a professional nursing staff or trainee to obtain a more accurate blood pressure value. With the advancement of the times, some manufacturers have designed these various sphygmomanometers into electronic sphygmomanometers, which measure the pressure on the arm or wrist mainly by a pressure sensing component, and pass the measured sense of pluralism. The measured parameters are used to calculate the diastolic blood pressure and the systolic blood pressure, but the heart beat characteristics of each of the test subjects are not the same, and the normal or not the cardiac pressure is estimated by using the sensing parameters alone, and it is impossible to actually introduce each of the waiting pressures. The heart characteristic of the tester is easy to sense the problem of misalignment. In addition, with the change of the concept of home care, there are many patients with inconvenient movements, long-term multi-home detection of blood pressure or blood sugar and other values, returned to the hospital for medical personnel to remotely monitor, but from the above can be known, many tests The instrument cannot be operated by itself, and it is inconvenient to carry, which limits the living space of the patient.
