Optical fiber continuous detection type blood pressure sensor and wearing device

The present invention relates to a blood pressure sensor, and more particularly to a fiber-optic continuous detection type blood pressure sensor and a wearable device thereof.

At present, the detection of blood pressure generally adopts a non-invasive detection method, and the non-invasive detection mainly includes an auscultation method (Korot's method) and an oscillation method (oscillometric method). The principle of auscultation is to collect Korotkoff sounds. The entire device includes a deflated cuff, a mercury pressure gauge and a stethoscope. The principle of the oscillation method is to determine the systolic blood pressure and the diastolic blood pressure by using the oscillometric principle of the pulse waveform, which is the method adopted by most non-invasive automatic blood pressure monitors at home and abroad.

However, both methods require charging and deflation of the cuff. The disadvantages are: due to the structure including the cuff, pump and valve, it is usually bulky and not portable; the filling and deflation process of the cuff can cause discomfort to the subject; if the cuff is used frequently, the tissue under the cuff And blood vessels may be damaged by frequent compression; continuous detection of blood pressure cannot be achieved because it takes a certain amount of time to charge and deflate.

In addition, recent research has shown that cuffless non-invasive blood pressure testing has become possible. It is a method of detecting blood pressure using the propagation speed of a pulse wave. The speed of pulse wave propagation refers to the speed at which the pulse wave propagates along the artery. A number of studies have shown that the speed of pulse wave propagation is related to blood pressure. One common method of detecting pulse wave velocity is to detect pulse wave travel time, which is the time it takes from the heart to a point on the radial artery. The pulse wave propagation time can be determined using a reference point on the ECG signal and a reference point on the pulse wave detected on the peripheral artery within the same cardiac cycle. Pulse waves can be detected optically, and this method is photoplethysmography. Photoelectric plethysmography expresses the change of blood flow under tissue by hitting light onto body tissue and detecting reflected, transmitted or scattered light from body tissue.

However, the detection device that uses the pulse wave propagation time or speed to detect blood pressure has the disadvantage that the detection of the pulse wave propagation time requires the use of the electrocardiographic detection device and the pulse wave detection device, and the detection device is numerous; and, in detection, in order to be accurate The time required for the pulse wave to travel from the heart to a reference point on the radial artery is not allowed to move freely. If the subject is active, the reference point will be inaccurate and repositioned. Therefore, the existing pulse wave detecting device is not suitable for continuous detection for a long time, and is only suitable for use in a clinic.

In the wristband-type human blood pressure non-invasive continuous detecting device disclosed in Chinese Patent No. CN 101288587, a pulse wave sensor probe having a spherical shape is used to detect a pulse wave of a human wrist and a radial artery, and a probe is secured by a compression spring. Good contact with the brachial artery of the human wrist, and through the positioning of the dimple and the olecranon, ensure the repeated positioning of the wristband and ensure that the wristband does not occur during the continuous detection process.

However, there is also the problem that the area in contact with the probe is the area where the pulse wave sensor detects the pulse wave of the human wrist and the radial artery, that is, the point-to-point area detection, and therefore, the wristband type blood pressure is non-invasively used. When continuously detecting the device, the probe of the pulse wave sensor must be aligned with the radial artery of the human wrist to align the dimple with the olecranon, and in the process of detection, if the wrist movement of the subject is inevitable The wristband is rotated, and the positioning of the probe and the wrist and iliac artery of the human wrist will be displaced. Therefore, the wristband-type human blood pressure non-invasive continuous detecting device will not accurately locate the wrist and iliac artery of the human body, and the blood pressure of the human body cannot be achieved. Non-invasive continuous testing of hours.

In view of the above, the present invention provides a fiber-optic continuous detection type blood pressure sensor, which aims to solve the complicated structure of the existing blood pressure detecting mode, not carrying the belt, damaging the skin of the subject, causing discomfort of the subject, and the subject is not free.

In this way, when the subject is active and causes the sensing belt to rotate or shift on the wrist of the human body, the sensing area can sense the pulse wave of the radial artery of the human wrist, that is, the wearing of the sensing belt does not require special positioning.

In addition, the outer surface of the induction belt is covered with an elastic layer, and the elastic layer can be elastically contracted so that the induction belt can be worn on different human wrists. The elastic layer has a certain elastic force, which makes the induction belt maintain a certain elastic contact stress on the wrist. Therefore, the induction belt is firmly worn on the wrist, and during the blood pressure detection, even if the subject has an activity, It is not easy to cause the phenomenon that the sensor belt and the wrist of the human body are dislocated.
