Abstract
The utility model provides a flexible pulse detecting probe based on pressure sensing array, which mainly comprises a special flexible silicon rubber substrate, a liquid sack, a pressure sensor, a wire and a rigid bottom board. A pressure sensitive unit is formed by the liquid sack and the pressure sensor in the liquid sack, can convert pressure signals into electric signals and obtain pressure information, and a certain number of the pressure sensitive units are arranged on the special flexible silicon rubber substrate, and are arranged in a M*N lattice array to form a pressure sensitive surface of a simulation finger surface. And the pressure sensitive units on the flexible pulse detecting probe have relevance with each other. A pulse wave under certain pressure sensitive unit can simultaneously affect other pressure sensitive units while offering the pressure data thereof. And the pressure information acquisition process similar to fingers of a doctor of traditional Chinese medicine can be accurately realized through utilizing interactional information.
Description
Technical field
This utility model belongs to biomedical detecting instrument field, relates generally to a kind of pulse condition detection device.
Background technology
Pulse-taking is a kind of diagnostic mode most characteristic in China's traditional medicine, and is with a long history, abundant in content, is the embodiment and the application of the traditional Chinese medical science " organic conception ", " dialectical opinion is controlled " essence spirit.From the 1950's, the scientific worker of China just is devoted to the research that pulse-taking objectifies, feature to common arteries and veins is explained with the mode of math equation, mechanical model or ideograph, aspect the formation of pulse condition mechanism and the physiological and pathological meaning more deep understanding is being arranged.
In the feeling the pulse of medical finger experience pulse condition information according to finger tip sense of touch, pressure sensation and vibration sense, the detection means of pulse condition is the objectify primary study content of research of pulse-taking.At present, single pressure sensor type detection scheme is comparatively commonly used, and it is simple in structure, but the pulse condition information that can detect is fewer, and the arteries and veins figure of output is single vascular pressure waveform.Though this waveform has the most information feature of pulse condition, can not reflect comprehensive sphygmogram characteristic.Relying on single pressure sensor that feeling the pulse process and fingering are simulated is unusual difficulty.
Facts have proved, it is more to want pulse condition detection device can be used to instruct tcm clinical practice to extract, science more, more intuitive information, by more perfect information analysis and processing, with the mutual confirmation of pulse wave spectrum practice, so the utility model proposes a kind of flexible pulse condition detection probe based on the pressure sensing array, traditional Chinese medical science corresponding angle from information retrieval, be to adopt flexible propagated sensation apparatus (corresponding to doctor's finger), after by damping system (corresponding to patient's epidermis and subcutaneous tissue) flexible conduit (corresponding to patient's radial artery) and pulsation flow of liquid wherein (corresponding to patient's blood flow) being carried out complicated dynamic analysis, through the doctor relatively, comprehensively, the pulse-taking conclusion that obtains at last.
Summary of the invention
A kind of flexible pulse condition detection probe that the utility model proposes based on the pressure sensing array.Its main purpose is to gather the pulse wave information at human body the area on the wrist over the radial artery where the pulse is felt for diagnosis place to make up three-dimensional pulse condition detection dynamic image by this flexibility pulse condition detection probe.Mainly comprise: special flexible silicone rubber matrix; The liquid capsule; Pressure transducer; Lead; Stiff baseplate, as shown in Figure 1.Pressure sensitive cells is made of liquid capsule and pressure transducer, settled pressure transducer in the liquid capsule, its work ultimate principle is the liquid capsule pressure-sensitive face pressurized after strain of being made by thin film, and liquid blister cavities body pressure inside pick off is converted to the signal of telecommunication with pressure signal, obtains pressure information.Settle the pressure sensitive cells of this some on the special flexible silicone rubber matrix, pressure sensitive cells is arranged into M * N lattice array, constitutes the presser sensor surface that simulation refers to face.
By each pressure sensitive cells in the flexible pulse condition detection probe, obtain the original pressure data of the pulse wave of each pressure sensitive cells below, there is relatedness between each pressure sensitive cells on this flexible pulse condition detection probe.When the itself pressure information is given in contribution, also affect other each pressure sensitive cells at the pulse wave under certain pressure sensitive cells simultaneously.Utilize these interactional information, then can realize the pressure information gatherer process of similar Chinese physician's finger comparatively exactly.

Specific embodiment:
The embodiments of the invention pressure sensitive cells adopts minor diameter liquid capsule.As shown in Figure 2, pressure sensitive cells is arranged into 8 * 8=64 lattice array, selects suitable liquid capsule size and its spacing to obtain the related information between each unit better when obtaining original pressure data.The liquid capsule diameter of present embodiment pressure sensitive cells is 1.2mm; Centre-to-centre spacing is 2mm.Pressure sensitive cells is imbedded at special flexible silicone rubber matrix surface.
Present embodiment adopts multichannel pmultiple amplifier to gather the real-time pressure value of each pressure sensitive cells, and these are sent into computer after signal digitalized.Under the cooperation of the related information between each pre-set pressure sensitive cells, obtain one group of non-isolated pulse wave data that contain interactive information that are used to present the two-dimensional pressure scattergram, the two-dimensional pressure scattergram of these fluctuating signals of continuous acquisition obtains visual three-dimensional pulse condition and detects dynamic image.
