As Figure 1-3, label is represented respectively:
Shown in Fig. 1-3, a kind of subjective pain metrization apparatus for evaluating is provided in the present embodiment, this device comprises that mainly computing machine 3 and the input mechanism 1 that at least one is connected with these computing machine 3 communications constitute.Wherein:
Wherein, housing is made up of four side plates, a base plate and a panel, and those side plates, base plate and panel are enclosed an accommodation space.Wherein, panel constitutes the guidance panel 7 of input mechanism 1, and this axis, guidance panel 7 upper edge has guide channel 8, and described guide channel 8 directions in guidance panel 7 upper edges are formed with the scale marker 5 of indication subjective feeling quantized value.
Linear potentiometer and data acquisition unit are arranged in the housing, and the push button 4 of linear potentiometer is disposed on this guidance panel 7 and can slides along described guide channel.When the linear potentiometer two ends are access in constant voltage, the voltage of its output terminal output has just reacted the position of slide plate, in other words, when promoting push button 4, its output voltage values is linear the change thereupon, by the judgement for its magnitude of voltage, can determine the slide plate position on the linear potentiometer, and then definite operator's subjective feeling quantized value.
When adopting linear potentiometer input quantized value, the judgement of making each time all moves to current location with push button 4 from last position, still in 0 to 10, select a numerical value to represent that the pain degree of oneself is example, scale marker 5 shows numerical value 0-10 successively, the pain degree in last judgement cycle is 3, current pain degree increases, the experimenter judges that according to the variation of pain degree the pain degree should be 5, and input the time need move to scale 5 from scale 3 with push button 4, this input mode obviously and experimenter's judgment model very identical.And the moving direction of push button 4 is represented enhancing or the weakening of subjective feeling, and shift motion is represented amplitude of variation, and very directly perceived of this input mode helps the experimenter accurately to judge, especially helps the relatively poor relatively experimenter of abstract thinking ability.
Data acquisition unit is mainly finished following function:
Voltage sample to linear potentiometer output keeps;
The voltage of gathering is carried out the A/D conversion, generate digital signal;
Send information to computing machine;
Accept the control of computing machine.
That is to say that data acquisition unit should comprise that sampling keeps module, analog-to-digital conversion module and communication module three parts, in the present embodiment, anti-interference in order to improve circuit, simplify circuit structure, use the single-chip microcomputer SAK-XC164CS-F20 that is programmed to finish the function of data acquisition unit.Signals sampling keeps and the A/D translation function is finished by the A/D modular converter of used single-chip microcomputer, and this module can be carried out accurate control able to programme switching time to signal sampling retention time and A/D.The output resistance that promotes the frequency of push button and input signal according to the testee is determined signal sampling and A/D switching time, and by calculating and the verification experimental verification sampling retention time is 1.664 milliseconds, A/D is 6.4 delicate switching time, uses 15 passages to carry out A/D and changes.

In addition, another main functional modules that computing machine 2 also comprises is the indication unit, default multiple different indication panel is tested different subjective feeling kinds, for example pain degree, stressed weight, depressed degree etc., and can set a plurality of different indication panels at each subjective feeling kind, for example the classification of pain degree can be divided into 10 grades, also can only be divided into 6 grades (painless, mild pains, moderate pain, severe pain, extremely pain and pain).Like this, guidance panel 7 only keeps basic graduated scale, and by selecting indication panel to make different explanations for graduated scale, a set of equipment can be used for different mental and physiology perception input like this.Therefore, because the classification difference of the subjective feeling quantized value that different indication panels are determined, therefore, computing machine 2 carries out normalized and is based on current selected indication panel and carries out, and change the corresponding movement of slider position on the display 3 on the shown indication panel with the subjective feeling quantized value that this normalized obtains.
In technique scheme, the stroke of linear potentiometer is not less than 40cm.The purpose of She Zhiing is like this: just as described in the background art, the experimenter often can accurately the decision content value by input the time.In this case, the hesitation degree in experimenter's input process/be sure of that degree can be reflected on the curve accurately when a judgement cyclic curve slope is more big, illustrates that the experimenter is more definite for the judgement of quantized value; More hesitate before shifting final selection quantized value onto, then jitter amplitude is more big, and vice versa.Therefore by calculating jitter amplitude and gradient, can give each flexible strategy of quantized value of judging the cycle and obtain to revise numerical value and fair curve, this flexible strategy scope then is the reaction of experimenter's certainty factor.For accurately with above-mentioned characteristic reaction on curve, the input travel of linear potentiometer should be not less than 40cm.
Above-mentioned each flexible strategy should be understood to a span, and it can be expressed as 1 ± x, and x is positive number, and when slope is more big, x is more big; Jitter amplitude is more big, and x is more big.In addition, the calculating of flexible strategy, also relevant with following factor:
The maximum slope of same experimenter in continuous a plurality of judgement cycles, this maximum slope can be understood as the experimenter and judges once the most firm in being subjected to the examination process.Different experimenters are when executable operations is moved, often because there is larger difference in the factor of personality or physical qualification, for example advanced in years the old is obviously agile not as juvenile, therefore at first select the most definite of same experimenter once to judge as judgement basis, and this maximum slope is as reference slope, and the slope in this other cycle of experimenter and the ratio of maximum slope then can reflect the hesitation degree in other cycle.
Subjective feeling kind and test-types, obviously, the different different then experimenters with the subjective feeling kind of test-types react different, and are therefore also very big to the influence of flexible strategy value.
Through applicant's protracted experience accumulation, the span of x is 0.25, that is to say that the flexible strategy scope should be between 0.75-1.25.
More than form for the structure of installing in the present embodiment, describe its principle of work below with reference to the said apparatus structure:
