Description

Pulse condition collecting device

Technical field

This utility model relates to a kind of tcm diagnosis device, is specifically related to a kind of pulse condition collecting device.This utility model also relates to a kind of pulse-tracing collection method.

Background technology

Traditional Chinese medical science diagnostic method commonly used comprises prestige, hears, asks, cuts, and wherein, pulse-taking is one of important diagnostic method of the traditional Chinese medical science.Traditional Chinese medical science finger feeling the pulse is finger tip applies the condition of different pressures to the radial artery pipe under (promptly floating, in, heavy pressure), relies on sense of touch, pressure sensation, vibration sense sensor to survey pulse condition information.Comprising to number, the rhythm and pace of moving things, drift along, power, thickness, information such as hard and soft, fluent, involved and abstruse.Therefore, to be construed as be the beat set of power of feeling the pulse pressure and pulse wave to the Chinese medicine pulse signal.

In existing human body pulse condition detection device, usually adopt the pressuring method of manual type, for example Chinese utility model patent description CN2420975Y (the February 28 calendar year 2001 day for announcing) disclosed a kind of intelligent Chinese medicine pulse checkout gear (seeing also Fig. 1), the defective of said apparatus is to find out best measurement position accurately, and the position of acquired signal can't repeat to realize.

Development along with technology; people also begin to adopt automatic pressurization metering system, but the pressuring method of setting does not adopt the structure of limit protection normally by program or computer-controlled on the hardware; like this, can damage when the program pulse that sensor heads presses to the people that breaks down always.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of pulse condition collecting device, and it can realize the pulse signal collection automatically, and gatherer process has the limit protection structure.For this reason, this utility model also will provide a kind of pulse-tracing collection method.

In order to solve above technical problem, this utility model provides a kind of pulse condition collecting device; Comprise a sensor cluster, described sensor cluster comprises that one is fixed on motor, the screw mandrel of fixedlying connected with described motor on the shell, is set in the outer lifting structure of described screw mandrel, and the sensor heads that is fixed on the lifting structure bottom.

This utility model adopts said structure to have the following advantages:

1, the gatherer process of pulse signal is realized automatically by motor, and the number of turns that motor rotates determines the stroke of probe lifting, has promptly guaranteed the accuracy and the repeatability of collection position.

2, utilize photoelectrical coupler that the extreme limit of travel position of lowering or hoisting gear is set, sensor heads damages human body to avoid program to make mistakes afterwards.

The specific embodiment

Be illustrated in figure 2 as a kind of embodiment of pulse condition collecting device of the present utility model, this device comprises base 1, positioning component 2 and sensor cluster 3.Earlier positioning component 2 is fixed on the staff wrist during use, sensor cluster 3 is installed on the positioning component detects again.

Fig. 4 and Fig. 5 are a kind of embodiment of sensor cluster of the present utility model, and Fig. 4 is outside sketch map, and Fig. 5 is the internal structure sketch map.Sensor cluster 3 of the present utility model comprises that one is fixed on motor 31, the screw mandrel 33 of fixedlying connected with motor 31 on the shell, is set in the outer lifting structure 34 of screw mandrel 33, and the sensor heads 35 that is fixed on lifting structure 34 bottoms.Between lifting structure 34 and the screw mandrel 33 by being threaded, the bottom of lifting structure 34 has a guide part 342, this guide part 342 is fastened in the non-circular acquisition window 36 (for example being square or rectangle) of sensor cluster 3 bottoms, when motor 31 clockwise or drive screw mandrel 33 when rotating counterclockwise and rotate, because guide part 342 and acquisition window 36 non-circular designs, thereby guide part 342 is stuck in the acquisition window 36 and can not rotates with screw mandrel, and then can make lifting structure 34 relative screw mandrels 33 rise or descend.

Preferably, lifting structure 34 has a protuberance 341, and sensor cluster 3 comprises that also at least one is fixed on the photoelectrical coupler 32 on the side wall of outer shell, and in the process that lifting structure 34 rises or descends, protuberance 341 passes photoelectrical coupler 32.As shown in Figure 5, up and down two photoelectrical couplers 32 can be set, the position of protuberance 341 when being separately positioned on the initial position of sensor heads and extreme position.The spacing range of two photoelectrical couplers is 0-25mm.

Be illustrated in figure 3 as a kind of embodiment of positioning component of the present utility model, has anchor window 21 on the positioning component 2, the bottom of sensor cluster 3 has acquisition window 36 (referring to Fig. 4), and sensor heads can pass acquisition window 36 and anchor window 21 is pressed in staff wrist collection pulse signal.

The shell of sensor cluster 3 is provided with buckle 37 (referring to Fig. 4), has draw-in groove 23 on the housing of positioning component 2, and buckle 37 is fastened in the draw-in groove 23 during installation.

Has the telltale mark 22 that is used to aim at the pulse position around the anchor window 21.Telltale mark 22 can be arranged on the center on anchor window 21 4 limits, and corresponding sensor heads is positioned at the center of acquisition window.

Pulse-tracing collection method detailed process of the present utility model comprises the steps:

(1) motor rotates and drives the lifting structure rising, to lifting structure arrival initial position.Judge that the method whether lifting structure reaches the limit of the position is: judge whether the protuberance of lifting structure arrives the position of first photoelectrical coupler.

(2) motor rotates the distance that drives a setting of lifting structure decline, judges whether lifting structure reaches the limit of the position, if then stop to measure, if otherwise sensor heads is gathered pressure signal.Judge that the method whether lifting structure reaches the limit of the position is: judge whether the protuberance of lifting structure arrives the position of second photoelectrical coupler.Preferably, sensor heads is 0-25mm in the stroke range of initial position and extreme position, easily the people is not caused injury if do not set extreme position.

(3) repeating step (2), the pressure signal of once gathering before whether the pressure signal of judging current collection is better than is if otherwise stop to measure.In the process of signals collecting, sensor heads is pressed in the pressure signal that the degree of depth decision of wrist senses, the signal that the too light pick off of pressing receives is very faint, the too ghost image of pressing has rung the signal that the pick off of beating of radial artery receives also can decay, and therefore the signal of suitable pressure acquisition is the strongest in the process of gathering.In the gatherer process from the initial position to the extreme position, signal strengthens gradually, when the signal of a certain station acquisition is weaker than a preceding signal, once is optimum pressure before then showing, Measuring Time is saved in the collection after can stopping.
