Embodiment 1

[0020] figure 1 It is the frame principle diagram of the blood pressure monitor of the first embodiment of the present invention. like figure 1 As shown, the sphygmomanometer includes a cuff 1 , an inflation and deflation device 2 , a pressure sensor 3 , a digital display unit 4 , a stethoscope head 5 , a microphone 6 , an audio processing device 7 , a speaker 8 and a power supply 15 . The cuff 1 has an air bag. The inflation and deflation device 2 communicates with the airbag and is used to inflate the airbag or release the air from the airbag. The pressure sensor 3 is used to measure the pressure in the airbag. Preferably, the airbag is connected to the main body of the sphygmomanometer through a catheter, and the pressure sensor 3 is installed in the main body of the sphygmomanometer to measure the pressure of the airbag through the catheter of the airbag. The digital display unit 4 is connected with the pressure sensor 3 for displaying the measured value of the pressure...

Embodiment 2

[0023] figure 2 It is the frame principle diagram of the blood pressure monitor of the second embodiment of the present invention. like figure 2 Shown, the sphygmomanometer of this embodiment and figure 1 The difference of the shown sphygmomanometer is that the sphygmomanometer of this embodiment also includes a main control unit 9, the main control unit 9 can be a processor (CPU) chip or a single-chip microcomputer, and the inflation and deflation device 2 is a device with an air pump. Fully automatic inflation and deflation device. The main control unit 9 is connected with the inflation and deflation device 2, the pressure sensor 3, and the digital display unit 4, receives the pressure value output by the pressure sensor 3, and controls the inflation and deflation of the inflation and deflation device according to the pressure value, and converts the received The pressure value is output to the digital display unit 4 in real time for display. In addition, the main cont...

Embodiment 3

[0025] image 3 It is the frame principle diagram of the blood pressure monitor of the second embodiment of the present invention. image 3 Sphygmomanometer shown with figure 2 The sphygmomanometer shown differs in that, image 3 The sphygmomanometer shown also comprises a memory 10 and a recording trigger 11 . The memory 10 is connected to the main control unit 9 , and the main control unit 9 can access values ​​to the memory 10 and also read data in the memory 10 . The memory 10 may be a permanent memory, a volatile memory, etc. commonly used in the industry, and may also be a cache of the main control unit 9 . That is, the main control unit 9 and the memory 10 can be integrated, for example, in the form of a microprocessor with a cache.

[0026] The recording triggering device 11 is connected with the main control unit 9, and is used to send control instructions to the main control unit 9, for example, instruct the main control unit 9 to store the currently received pr...

Abstract

The invention relates to a sphygmomanometer, which comprises a cuff (1) with a gasbag, a inflation and deflation device (2), a pressure sensor (3), a digital display unit (4), a stethoscope head (5), a microphone (6), an audio processing circuit (7), a speaker (8) and a power supply, wherein, the inflation and deflation device (2) is communicated with the gasbag of the cuff, the pressure sensor (3) is used for detecting the pressure of the gasbag, the digital display unit (4) is connected with the pressure sensor (3) and used for displaying pressure value, the stethoscope head (5) is used for getting pulse sound, the microphone (6) is arranged in an sound induction tube of the stethoscope head (5) and used for receiving the pulse sounds get by the stethoscope head (5), the audio processing circuit (7) is connected with the microphone (6) and receives and linearly processes outputted audio signal from the microphone (6), the speaker (8) which is connected with the audio processing circuit (7) and is used for broadcasting the processed audio signal by the audio processing circuit (7), the power supply supplies power to the sphygmomanometer. The sphygmomanometer has the advantages of accurate and reliable measuring result, convenient hear korotkoff sounds and environmental protection without needing to use mercury.

Description

technical field [0001] The present invention relates to a sphygmomanometer, more particularly, to a sphygmomanometer using the Korotkoff sound principle. Background technique [0002] Blood pressure is one of the important physiological parameters of the human body. Accurate measurement of blood pressure is conducive to early detection and identification of hypertension types, and reasonable treatment suggestions are put forward. At present, methods for measuring blood pressure are divided into two types: the Korotkoff method and the oscillometric method. [0003] The Korotkoff sound method is to pressurize the blood vessel through the cuff to block the blood flow, and then slowly deflate it. At the same time, listen to the pulse sound with a stethoscope. You can hear a strong pulse sound through the stethoscope, and it gradually becomes lighter. Until you hear a smoother, more normal pulse. The high pressure corresponding to the first pulse sound is the systolic blood pre...
