Description

Tongue pressure sphygmomanometer

Technical field

The invention relates to an electronic sphygmomanometer, in particular to a tongue pressure sphygmomanometer. Background technique

Current blood pressure measurement techniques: divided into direct and indirect methods.

The direct method is a traumatic method; the indirect method has two main types: Korotkoff sound method: Detecting the appearance and disappearance of Korotkoff sound. In 1905, it was proposed by former Soviet doctor N. Korotkov. The advantage is that the measurement is simple, the disadvantage is that it has certain subjectivity and is susceptible to environmental noise interference; oscillometric method: detecting the static pressure and shock wave of the gas in the cuff, that is, the method used by the second and third generation electronic sphygmomanometer. The principle is to detect gas oscillations in the cuff and to calculate the data by multiple calculations. The advantages are simple operation, high repeatability and consistency. The disadvantage is that it is susceptible to external shocks and can cause data misalignment after complicated calculations.

Current status of blood pressure measuring instruments:

Mercury sphygmomanometer and stethoscope. The advantage is that the measurement is simple and conforms to the Kosher sound method specified by the International Health Organization. The disadvantage is that mercury is highly volatile and has a total ban. On the other hand, due to the large proportion of mercury, mercury manometers are difficult to accurately reflect the instantaneous changes in blood pressure during each stroke. Blood Pressure Monitor. At present, the technology of electronic blood pressure monitors is divided into three generations. From the measurement at the time of decompression to the measurement at the time of pressurization, that is, the measurement from the systolic pressure to the diastolic pressure is converted from the diastolic pressure to the systolic pressure, and the technique is oscillometric. (Because the wrist electronic sphygmomanometer is not suitable for patients with blood circulation disorders, only the upper arm electronic sphygmomanometer is described here). The disadvantages are: Not recognized by the World Health Organization; b) Because the air sleeve exhaust speed is usually set according to the medium and thin arms, the actual user's arm thickness is different, which affects the measurement accuracy; the rubber used in the trachea is roughly half a year to one year old. Therefore, the exhaust speed and pressure are affected, further affecting the measurement accuracy; when the air sleeve is pressurized to 200mmHg, people are prone to pressure and discomfort; because the electronic sphygmomanometer mainly uses servo-pressurized air pump, electronically controlled exhaust valve and Software, and the popularity of this technology patent is huge. The intelligent pressurization technique predicts the systolic pressure of the user, and the air pump has a large disturbance during pressurization, which makes it difficult to detect the blood pressure signal.

Current status of blood pressure measurement methods and locations:

The current method of blood pressure measurement is mainly air sleeve pressure measurement. The disadvantage is due to the user's muscle fat The difference in fat causes a difference in pressure when the blood vessels are blocked, so the measurement data may be out of alignment. The current position of blood pressure measurement is:

Brachial artery: Wrap the cuff around the upper arm of the user, with the lower end of the cuff 2-3 from the elbow. cm.

Lower limbs: Wrap the cuff around the radial artery, 3-5 cm from the armpit at the lower end. The disadvantage is that the size of the cuff is quite different from that of a conventional sphygmomanometer and is not accurate. In addition, there are many branches of the radial artery, and it is difficult to obtain the required data.
