Problems solved by technology

[0004] In the same way, in the fifth phase of "disappearing sound", the sound changes from heavy to light until it is inaudible to the human ear, and medical science recognizes that the external pressure value corresponding to the last sound can be heard is recorded as the diastolic pressure, so hearing will also occur Therefore, doctors (measurers) with different hearings will produce auditory errors, and it is difficult to accurately obtain blood pressure Korotkoff sounds without professional training

Embodiment 1

[0021] Embodiment 1: A method for automatically detecting and acquiring blood pressure Korotkoff sounds, such as figure 1 As shown, the method steps are as follows:

[0022] a. Use the electronic auscultation probe 1 to pick up the blood pressure Korotkoff sound, first wrap the cuff 2 around the human arm, place the electronic auscultation probe 1 in the cuff 2 on the position of the human arm artery, then tighten the cuff 2, The air bag inside 2 communicates with the external inflatable device through the air bag catheter. After the air bag is inflated, the electronic auscultation probe 1 is closely attached to the position of the arm artery;

[0023] b. The decibel tester 4 is electrically connected with the electronic auscultation probe 1, the electronic auscultation probe 1 is responsible for collecting the pulse beat decibel size of the human arm artery position, and the decibel tester 4 can measure the corresponding size of the blood pressure Korotkoff sound picked up by...

Embodiment 2

[0027] Embodiment 2: A method for automatically detecting and acquiring blood pressure Korotkoff sounds, such as figure 1 and 2 As shown, the buzzer 6 is provided with a loudspeaker unit, and the loudspeaker unit has the function of amplifying the buzzer 6 to send out the sound, and the decibel value tested by the decibel tester 4 is enlarged in the buzzer 6 by the loudspeaker unit Integer multiples, the amplified sound is transmitted from the buzzer 6, and the multiple of the decibel value of the amplification unit has three gears, which will be enlarged by 1.5 times, 2 times, and 3 times respectively on the basis of the original decibel value. A remote controller and a light-emitting diode are connected in series through the circuit. The remote controller can adjust the position of the PA unit. The control unit in the remote controller is connected to the frequency module in the PA unit. The control unit adjusts the frequency of the PA unit, thereby adjusting different Gear...

Abstract

The invention discloses a method for automatically detecting and acquiring blood pressure Korotkoff sound. The method includes the steps: a picking up the blood pressure Korotkoff sound by an electronic stethoscope probe; b electrically connecting a decibel testing instrument with the electronic stethoscope probe and testing the decibel of the blood pressure Korotkoff sound picked by the electronic stethoscope probe by the decibel testing instrument; c electrically connecting a controller with the decibel testing instrument, and converting the decibel tested by the decibel testing instrument into electric signals by the controller; d electrically connecting a buzzer with the controller, controlling the buzzer to emit sound with different decibels according to different frequencies of the electric signals by the controller, and amplifying the decibel of the Korotkoff sound at the artery of a human arm by the buzzer. Testers such as medical workers with different hearings can eliminate hearing errors, and the Korotkoff sound is more accurately heard, so that more accurate blood pressure data are conveniently acquired.

Description

technical field [0001] The invention relates to the technology in the field of blood pressure measurement, in particular to a method for automatically detecting and acquiring blood pressure Korotkoff sounds. Background technique [0002] There are two main methods of non-invasive blood pressure measurement: auscultation method (Krotkoff sound method) and oscillometric method. The auscultation method is to tie the armband of the sphygmomanometer to the pulse position of the brachial artery of the upper arm, inflate and pressurize the brachial artery, and then Then deflate and decompress. As the external pressure drops, the blood flow opens the blood vessel again, and the same rhythmic sound as the heartbeat is issued, which is the Korotkoff sound. [0003] The Korotkoff sound is obtained by manual auscultation, and doctors (measurers) with different hearing will produce auditory errors. The operation is inconvenient. Without professional training, it is impossible to measur...
