Description

Technical Field

[0001] The present invention relates to a blood pressure detection device and a use method, in particular to a wrist arterial blood pressure detection device and a use method, belonging to the technical field of medical auxiliary products. Background Art

[0002] The wrist blood pressure monitor uses a cuff to pressurize the radial artery in the wrist to block arterial blood flow. The blood pressure monitor then begins to slowly depressurize the artery and monitors the sound and small pressure pulses transmitted from the arm to the cuff during the process. The instrument can automatically identify these small pulses and identify the systolic and diastolic pressures to derive the blood pressure value.

[0003] Existing wrist blood pressure monitors measure the radial artery blood pressure at the wrist, and the arteries in this area are thinner and easily affected by hand movements. Therefore, its measurement accuracy may be slightly lower than that of an arm blood pressure monitor. For special groups with severe arteriosclerosis, arrhythmias, peripheral circulatory disorders, etc., the measurement results may not be accurate enough. At the same time, factors such as incorrect measurement posture may also affect the accuracy of the measurement. Moreover, for most middle-aged and elderly people or patients with vascular system diseases, using a wrist blood pressure monitor may not produce accurate measurement results.

Start the infrared calibrator on the blood pressure meter. Use the infrared calibrator to rotate the infrared calibrator so that the light spot of the infrared calibrator is aligned with the user's heart. Adjust the wrist level according to the prompts of the level calibrator. Specifically: When the arm is lifted upward, the infrared calibrator rotates inside the infrared calibrator rotating slot and always keeps a horizontal state under the action of the gravity block, and adjusts the height of the arm through the infrared meter; Then, the wrist is in a horizontal position upward.

[0016] The present invention has at least the following beneficial effects: 1. The belt is tightened by driving the gear, the structural strength is high, and the service life is greatly improved. The air pump is used to inflate the inside of the pressurized airbag to achieve the purpose of rapid inflation and pressurize the wrist. After the pressurized airbag is inflated, it is evenly distributed inside the belt through multiple guide sliders. Therefore, the wrist can be pressurized in all directions at the same time, greatly improving the efficiency of detection.

[0017] 2. When the wrist moves, the infrared calibrator is always in a horizontal state under the action of the gravity block. An infrared meter is fixed inside the infrared mounting slot. Under the action of the infrared calibrator, the infrared meter is in a horizontal state. After starting the infrared meter, the red dot emitted by the infrared meter is always in a horizontal state. Therefore, the height of the wrist can be determined by the position of the red dot, which facilitates adjusting the wrist to a position flush with the heart, thereby improving the accuracy of detection.

[0018] 3. Turning the wrist upward helps improve the accuracy of the test. In order to ensure that the wrist is flush with the horizontal plane, a horizontal calibrator is fixed on the dial cover of the blood pressure meter. A metal ball is rolled inside the horizontal calibrator. That is to say, when the wrist turns, the metal ball inside the horizontal calibrator will roll to the lower side of the wrist. When the metal ball passes through one of the protrusions and reaches the pressure switch, the corresponding indicator light will flash, and then the wrist can be adjusted according to the indication.

[0019] 4. Under the action of the gravity circle, the limit circle on the support mechanism rotates and becomes perpendicular to the desktop. The multi-section electric telescopic rod starts to counteract the desktop and support the wrist to prevent the shaking of the wrist from affecting the detection accuracy and improve the stability of the wrist. An anti-slip pad is fixed at the bottom of the gravity circle.

10. A method for using a wrist arterial blood pressure detection device, characterized in that: A wrist arterial blood pressure detection device according to any one of claims 1 to 9 is used, comprising the following steps: Step 1: Wearing, first pull the strap (2) outwards, put the patient's wrist inside the strap (2), and adjust the arm; Step 2: Calibration. Start the infrared calibrator (8) on the blood pressure meter dial (1). Use the infrared calibrator (8) to rotate the infrared ray meter (802) to aim the light spot at the user's heart. Adjust the wrist level according to the prompt of the level calibrator (17). Specifically: When the arm is lifted upward, the infrared calibration instrument (8) rotates inside the infrared calibration instrument rotation slot (103) and always maintains a horizontal state under the action of the gravity block (801), and the height of the arm is adjusted by the infrared instrument (802); Then, when the wrist is in an upward horizontal state, once the wrist is tilted, the metal ball (19) will be triggered to roll inside the level calibration instrument (17), and the horizontal degree of the wrist will be adjusted according to the prompt of the indicator body (21); Step 3: Support, the gravity ring (603) on the support mechanism (6) rotates the vertical tabletop downward under the action of gravity, and the multi-section electric telescopic rod (602) is activated to support the hand; Step 4: Pressurize, continue to start the band motor (4) to drive the free end of the band (2) into the interior of the blood pressure dial (1), and pressurize the wrist through the pressurized air bag (3) until the blood flow of the radial artery is blocked; Step 5: Decompression and monitoring: After the pressure is increased to a certain level, the pressure is slowly reduced through the quick exhaust solenoid valve (11).
