Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a sphygmomanometer. BACKGROUND

[0002] Blood pressure refers to the pressure exerted by blood on the vessel wall, which is determined by the heart pumping and the resistance of blood vessels. The measurement of blood pressure is very important for assessing cardiovascular health and monitoring disease status.

[0003] Many existing diseases (such as subclavian artery occlusion, multiple aortitis and aortic dissection, etc.) can cause blood pressure asymmetry between the two upper arms, resulting in excessive blood pressure difference between the two upper arms (systolic pressure difference ≥10mmHg or diastolic pressure difference ≥5mmHg). The blood pressure difference can be used to screen and diagnose the specific condition of the patient, determine whether there is peripheral arterial vascular disease, predict the risk of the patient suffering from the disease, and promote the treatment of the disease. Currently, ordinary sphygmomanometers need to measure the blood pressure of the left and right upper limbs respectively to determine whether there is excessive blood pressure difference between the two upper arms. When measuring blood pressure with a sphygmomanometer, the height of the sphygmomanometer and the position of the patient's heart should be on the same horizontal plane. For the elderly or children, etc. who are not physically fit, the arm will inevitably vibrate slightly when using an ordinary sphygmomanometer, resulting in inaccurate blood pressure measurement.

[0024] Further, a motor box is arranged in the middle of the inside of the lifting box 13. An upper motor 1301 and a lower motor 1302 are fixedly arranged in the motor box. The output end of the upper motor 1301 is connected with a first driving wheel 1303. The first driving wheel 1303 is engaged with a first driven wheel 1304.

A first guide rod 1306 is arranged above the first double-section screw rod 1305. The two ends of the first guide rod 1306 are fixedly connected with a limiting plate 1307. The limiting plate 1307 is also used to prevent the outer support block 151 and the inner support block 152 from colliding due to excessive distance.
