Description

A kind of pulse condition ultrasonic TOFD harvester and method

Technical field

The present invention relates to intelligent pulse condition collecting device and acquisition method.

Background technology

Chinese medical is seized of consequence in world's medical system, and Chinese pulse-taking is taken the course of its own, established one's own system at medical domain, has the history of more than 2,000 year.Feeling the pulse is the conventional means of tcm diagnosis, and has accumulated rich experience, becomes the representational very precious legacy of the traditional Chinese medical science.

Pulse condition refers to when doctor feels the pulse, the image that beat pulse should refer to.Its concentrated expression the depth of arteries and veins position, to speed, the rhythm and pace of moving things of number evenly, the power of the size of shape and length, strength, and whether the oncoming force of pulse fluent etc.The task of pulse-taking is exactly by the variation of position, number, shape, gesture and its character of examination pulse, to reach the position of identification disease, and the situation of character and the prosperity and decline of body good and evil.

The description of Chinese patent CN101103906B discloses a kind of pulse condition collecting device and using method thereof, comprises sensor group, pulse-tracing collection, control and processing module, and the Man Machine Interface of LCD MODULE and input key composition; Also comprise Inflatable wrist support, electromagnetic valve and micro air pump, can realize feeling the pulse lightly, in get, the maneuver such as taking the pulse heavily, to detect pulse condition; But this equipment still has more assembly, and manufacturing cost is larger, huge volume can only be also the field that is confined to Medical Instruments, is unfavorable for carrying.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and be easy to carry, show in real time the pulse condition ultrasonic TOFD harvester of pulse condition.

Technical scheme of the present invention is: a kind of pulse condition ultrasonic TOFD harvester, comprise that one is arranged near the apparatus main body of human body wrist radial artery, apparatus main body is provided with display, in apparatus main body, be provided with power supply circuits, functional circuit, storage element and microprocessor, microprocessor is also connected with ultrasonic TOFD probe, micro-pressure sensor and straight line micro machine by functional circuit, and micro-pressure sensor, straight line micro machine and ultrasonic TOFD probe are connected.

Described ultrasonic TOFD probe comprises a transmitting wafer and a reception wafer, and described transmitting wafer and reception wafer are arranged at respectively the both sides of radial artery.

Described ultrasonic TOFD probe has three groups, and three groups of described ultrasonic TOFD probes are arranged at respectively three positions of cun,guan,chi of wrist.

Described apparatus main body is intelligent watch.

A kind of pulse condition ultrasonic TOFD acquisition method, it comprises the following steps:

S1, pulse condition ultrasonic TOFD harvester is worn on to human body wrist, microprocessor sends signal driver ultrasonic TOFD probe, micro-pressure sensor and straight line micro machine.

S2, micro-pressure sensor and the aggregate motion of straight line micro machine, drive the ultrasonic TOFD probe of array to carry out the variation of the body surface degree of depth.

The transmitting wafer of S3, ultrasonic TOFD probe sends propagation compressional wave, utilizes the diffracted wave of radial artery end to measure tremulous pulse oneself height, receive wafer and receive diffracted wave, the signal of reception through Wave data converting transmission to microprocessor.

S4, microprocessor convert Wave data to word amount data, by with memory element in pulse profile data storehouse compare, by the definition format text display that meets result on display.

In the present invention, pulse condition ultrasound acquisition means is utilized the position of hyperacoustic penetrability to radial artery, size, the depth is measured, miniature linear carries out automatic probe positions adjustment, to change hyperacoustic transmitting site, simulate the " floating of theory of Chinese medical science, in, heavy ", and pop one's head in by pulse condition ultrasound acquisition means " very little, close, chi " array simulates three nine of the traditional Chinese medical science completely and examines, the transmitting wafer of pulse condition Vltrasonic device and reception wafer are placed in radial artery both sides by certain distance, by the mode of operation of one of a receipts, transmitting wafer sends compressional wave, utilize the diffracted wave of radial artery end to measure contraction and the diastole of tremulous pulse, can depict the peak valley oscillogram of arterial pulse.

The invention has the beneficial effects as follows: the present invention adopts ultrasonic TOFD probe simulation traditional Chinese medical science maneuver to gather pulse condition, and all devices are integrated in intelligent watch, compared with prior art simpler, small and exquisite, are more suitable in portable type measuring, and cost is lower simultaneously.

Brief description of the drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is overall appearance schematic diagram of the present invention.

Detailed description of the invention

Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.

Shown in Fig. 1 and Fig. 2, wherein 1 is ultrasound wave compressional wave probe, and frequency probe is 2MHZ, and main work is to find wrist position of radial artery, 2 is blood oxygen red light sensor, operation wavelength is 950nm, by the spectrum analysis of the reflection remaining light after hemoglobin is absorbed, draw corresponding blood oxygen levels, by the calculation of data model, oximetry data is fitted to pressure value simultaneously, 3 is body temperature infrared excess derivative sensor, wave-length coverage at 5-14 μ m is carried out temperature sensing, and by computational model, body temperature is collected to system database, 4 is ultrasonic TOFD double crystal probe, the object using is in pairs to accomplish receipts, composition TOFD group pattern, by to very little, close, the chi three not linear transducer array of position can be simulated doctor's maneuver hands position completely, and the aggregate motion with stepping straight line micro machine 6 by micro-pressure sensor 5, the body surface degree of depth of array TOFD probe is changed, with floating of simulation doctor, in, heavy maneuver, pulse condition ultrasound acquisition means is that transmitting wafer and reception wafer are placed in radial artery both sides by certain distance, transmitting wafer sends propagation compressional wave, utilize the diffracted wave of radial artery end to measure tremulous pulse oneself height, in the place that there is no tremulous pulse, the signal obtaining is only the echo in the lateral wave of human body surface propagation and surface of bone reflection, but in the place that has tremulous pulse, also can receive the diffracted wave from tremulous pulse upper end and lower end, so time difference arriving by each signal gathering on figure, can obtain the degree of depth and the size of tremulous pulse, fight in number to rapid pulse at one, the contraction of tremulous pulse and expansion variation can be reflected to the position of diffracted wave in real time with strong and weak, these signals of collecting also can be through Wave data conversion, processed by FPGA, be transformed into digital data, by with SD card in pulse profile data storehouse compare, the result feedback meeting to output module, and utilize data base to carry out watch displays to the definition format text that meets result.
