Abstract
A finger ring type physiological information monitor for acquiring, processing and displaying the physiological information of a user, such as cardiac rhythm and blood pressure, is composed of main body, finger supporting band, measuring unit, display unit, processing unit and finger ring.
Description
Technical field
The present invention relates to a kind of independent sets accepted way of doing sth physiologic information monitoring device, relate in particular to a kind of stand-alone integrated finger ring type physiologic information monitoring device.
Technical background
World population is aging day by day.Statistical data shows, expects the year two thousand fifty, and the quantity of 60 years old or above population will reach 2,000,000,000.Chronic disease is the subject matter that influences the senior health and fitness, and heart disease, hypertension and the diabetes sickness rate in the old people all is higher than youngster usually.Disease that the old people takes a disease is tending towards chronicity and symptom is not obvious.According to estimates, the annual whole world has 16,600, and 000 people dies from cardiovascular disease, and untreated hypertension is a major risk factors that life is had the cardiovascular disease of serious threat, thereby hypertension is the major issue that influences public health.But unfortunately most of hyperpietics do not have manifest symptom.Usually when symptom became tangible, disease had arrived very serious stage.In the U.S. 5,000 ten thousand hypertension populations are arranged approximately at present, 100,000,000 hypertension populations are arranged approximately in China.Because it is rapid to suffer from the population growth of chronic disease, it is particularly important that the physiologic information monitoring device just seems.
Now, many different physiologic information monitoring devices are arranged.Wherein a kind of is Cardio kickboxing, is widely used in family and the training athlete.Present Cardio kickboxing is normally determined heart rate according to electrocardiosignal or photoplethaysmography signal.By detecting monitor that electrocardiosignal determines heart rate at chest, detailed description is arranged in 247 and 6,553,251 at United States Patent (USP) 6,553.This monitor uses and is inconvenient, because it needs user to use a belt that has electrode to be entangled in chest, shows heart rate with a device of separating simultaneously.This kind measurement can cause discomfort, and needs the more intervention of user.
A kind of physiologic information monitoring device based on photoplethaysmography signal or electrocardiosignal is to occur with the form of wrist-watch, as United States Patent (USP) 4,407,295 and 4,230,127 disclosed like that, the device of this mode can be operated more conveniently.In use, user will be placed on a finger on the measuring unit, can't realize the long-time continuous monitoring like this.Simultaneously, the freedom of movement of user also has been limited when measuring.A method that addresses this problem is pick off to be fixed to point go up and detection photoplethaysmography signal, then signal is passed to wrist-watch.United States Patent (USP) 4,305,401 and 4,338,950 have described such design.But because it need couple together two devices that separate with a cable, thereby its design volume is bigger, inconvenient long-time the measurement and athlete's use.
Another kind of monitoring device based on the photoplethaysmography method is designed to an independently finger ring, and it can be worn on hand and need not the cable connection continuously, United States Patent (USP) 6,608, and 562 B1,5,964,701 and 6,402,690 B1 have described such design.But, its demonstration and/or calculate crucial physiologic information and still need an isolating unit.Although United States Patent (USP) 5,539,706 and Chinese patent 93,247,546 all described the self-contained unit of display device integrated, their device volume is bigger, rather than occurs with a kind of form of comfortable wearable finger ring type device.
The public recognizes that day by day hypertension is a kind of disease of serious harm health, and this has promoted the development at the blood pressure measurement technology of individual's use.The introspection blood pressure can reduce diagnosis and the required outpatient service access times of treatment hypertension.The employed technology of different blood pressure measuring devices can be divided into two classes: intrusive mood measuring device and non-intrusion measurement device.In the non-intrusion measurement device, be applicable to comparatively that based on the method in pulse wave transmission time introspection and family use.The pulse wave transmission time is meant that heart contraction and pulse wave arrive the time difference of body extremity position.The systaltic time can be represented with a characteristic point (the after one's own heart summit of the R type ripple in each cardiac cycle in the electric signal waveform).The time of pulse wave arrival body extremity position can be represented with the characteristic point in each cardiac cycle in the light Power Capacity trace signal.In case obtained the pulse wave transmission time, corresponding pressure value just can obtain by the regression equation of setting up when calibrating in advance.The method of this definite blood pressure is a non-intrusion type, need not to use the cuff that can charge and discharge gas, and can obtain corresponding to the pressure value of heartbeat each time.United States Patent (USP) 4,869,262,5,316,008 and 20010012916 disclose the blood pressure measuring device based on the pulse wave transmission time.Although these devices are of portable form, they are typically designed to the form of wrist-watch or handheld device.And the finger ring type design can conveniently wear, be easy to use, the application scenario is wide, and makes blood pressure measurement more convenient.
Utilize the device of photoplethaysmography method detection signal to comprise a measuring unit, it has a light-emitting device, as light emitting diode, light is injected into the surface of measuring position, as finger, ear-lobe or forehead and an optical pickup apparatus, as phototriode, detect from the light of measuring position reflection or transmission.Because arteriopalmus causes the variation of blood flow in the blood vessel, so the also corresponding change of the absorption of light, reflection and scattering.By the detected light intensity of optical pickup apparatus respective change takes place also, this light intensity signal can be further processed and analyze after being converted into the signal of telecommunication.Comprise in the problem that is run into when the terminal position of health detects the photoplethaysmography signal under the non-static state: 1) motion owing to measuring position blood flow circulation flip-flop and measuring unit relative measurement surface of position produces the motion noise; 2) the needed heavy current of driven for emitting lights device causes higher power consumption.
