Description

Background
At present, a volume compensation method (also called as a "blood vessel unloaded method") is generally used for non-invasive blood pressure measurement, and utilizes the principle that when the external pressure of a blood vessel is equal to the internal pressure of the blood vessel at any time, the diameter of the blood vessel is not embedded on the diameter of the blood vessel in an unloaded state along with the change of the waveform of the internal pressure of the blood vessel (namely, no pulsation occurs). Such methods generally comprise a balloon (or sac) for externally pressurizing the artery and a photosensor for monitoring the arterial pulse, and further a feedback control system for controlling the pressure of the balloon by the detected arterial pulse, wherein the photosensor is disposed on the inner wall of the balloon, see fig. 5. The reflection type photoelectric sensor is used for measuring the blood pressure of the radial artery on the wrist, the pulse rate wave signal is detected while the pressure is applied to the blood vessel of a detected person, then the pulse rate wave signal is used as a feedback signal, the pressure of the air bag applied to the blood vessel is adjusted to change according to the waveform of the pulse wave, so that the pressure opposite to the blood pressure waveform inside the radial artery is applied to the radial artery, and once the diameter of the blood vessel of the radial artery does not change along with the blood pressure waveform inside the blood vessel any more, namely when the blood vessel is in an unloaded state, the pressure value and the waveform inside the air bag, namely the continuous blood pressure value and the blood pressure waveform inside the artery, are continuously measured.
The prior volume compensation method has the following defects:
1. the existing photoelectric sensor is adhered to the inner side of the air bag, and the light incidence path is light-emitting part-air bag-gap between the air bag and the positioning rubber ring-gap between the positioning rubber ring and the skin-skin tissue-blood vessel; the reflection path is a blood vessel-skin tissue-a gap between the skin and the positioning rubber ring-a gap between the positioning rubber ring and the air bag-the photoelectric receiving part. Attenuation such as absorption, reflection, refraction and the like occurs in the light propagation path, and noise is easily introduced due to the influence of external factors.
2. Because the half-power angle of a light-emitting part in the original photoelectric sensor is small and the emission distance is long, the radiation intensity of the original sensor irradiated on the radial artery changes along with the movement of the air bag in the blood pressure measurement process, so that the variation of non-blood volume change is introduced, and the blood pressure measurement distortion is caused.
3. The existing photoelectric sensor production process is limited by factors such as the structure of the existing air bag, and the matching bonding with the air bag is completed through procedures such as positioning, bending, bonding, pressing and the like.
4. The existing photoelectric sensor is influenced by an air bag structure, and the expansibility of the array layout is limited.
It is therefore desirable to develop a device for fixing or positioning the photoelectric sensor so as to avoid the influence of the air bag.

Layout and analysis of transmitting 311 and receiving 312 components
The volume compensation method utilizes the principle of photoplethysmography to measure blood pressure, and photoplethysmography (PPG) is a non-invasive detection method for detecting blood volume change in living body tissue by means of photoelectric means. Wherein the absorption of light by skin, muscle and tissue is kept constant in the whole blood circulation, and the blood volume in the skin is pulsated under the action of the contraction and relaxation of the heart. When the heart contracts, the blood volume of the peripheral blood vessel is the maximum, the light absorption amount is also the maximum, and the detected light intensity is the minimum; in diastole, on the contrary, the peripheral blood vessel has the least blood volume and the maximum detected light intensity, so that the light intensity detected by the photoelectric receiver is in pulsatile change.
The main parameters of the infrared light-emitting diode are as follows: peak wavelength λ p, radiation intensity Ie, half-power angle θ 1/2, and the like.
λ p: the wavelength corresponding to the maximum intensity of the relative light radiation.
Ie: the radiation energy delivered by a point radiation source in a unit solid angle in a certain direction is proportional to the input current and proportional to the emission distance.
As shown in fig. 4, in the simple optical path model for measuring the volume change of blood in the radial artery for the transmitting unit 311 and the receiving unit 312, due to human variability, the radial artery of most people has a depth L from the skin in an interval of about 2-10mm, where θ is the half-power angle of the light emitting/receiving unit, S is the distance between the transmitting unit 311 and the receiving unit 312, and L is the distance between the center of the radial artery and the skin surface.
Assuming that the transmitting unit 311 and the receiving unit 312 are uniformly distributed on two sides of the radial artery, and the distance is constant, for different people, since the depths of the radial artery from the skin are different, that is, L is different, when the radial artery is closer to the skin, since the half-power angle θ of the transmitting unit 311 and the receiving unit 312 is an inherent parameter of the device, with the decrease of L, the radial artery is greatly likely not in the normal radiation range of the optoelectronic device; when the radial artery is far from the skin, the radial artery is in the normal radiation range of the photoelectric device, the radiation intensity is weakened along with the increase of the emission distance, and the radiation intensity can be enhanced by increasing the input current of the emission part 311.
Assuming that the distance L from the radial artery to the skin is constant, the transmitting unit 311 and the receiving unit 312 are uniformly distributed on both sides of the radial artery, and by reducing the distance between the transmitting unit 311 and the receiving unit 312, both the transmitting unit 311 and the receiving unit 312 gradually reach the optimal operating state as the distance S between the light emitting unit and the receiving unit is reduced; when the distance S between the transmitting section 311 and the receiving section 312 increases, both the transmitting section 311 and the receiving section 312 gradually deviate from the normal operating interval as the distance S between the transmitting section 311 and the receiving section 312 increases.
In summary, it is desirable that the distance between the transmitting unit 311 and the receiving unit 312 is as small as possible, and the transmitting unit 311 and the receiving unit 312 have a half power angle as large as possible. The distance of the radial artery of a normal person from the surface of the skin is within the range of 2-10mm, the external diameter of the radial artery is within the range of 1.6-3.2 mm, and after a large number of tests, under the condition of meeting the measurement requirement, meeting the structural limitation of a positioning rubber ring and improving the comfort of a human body in the measurement process, the utility model discloses a photoelectric component with a half-power angle of 130 degrees is adopted, the interval is 7.5mm, and in order to improve the testable range of a sensor, 3 transmitting parts 311 are adopted and are connected in series and arranged in parallel to the radial artery; 3 receiving elements 312 are used, receiving independently, arranged parallel to the radial artery.
Under the condition of meeting the test requirement, when the distance between the transmitting part 311 and the receiving part 312 is less than 7.5mm, a photoelectric device with a slightly smaller half-power angle theta can be selected; greater than 7.5mm, photovoltaic devices with larger half power angles θ may be selected.
When the transmitting unit 311 and the receiving unit 312 are arranged parallel to the radial artery, the number of the transmitting unit 311 and the receiving unit 312 can be increased or decreased, not only the number of the transmitting unit 311 and the receiving unit 312 is equal, but also the number of the transmitting unit 311 and the number of the receiving unit 312 are more; there may be fewer transmitting units 311 and more receiving units 312.
