[0026] The data integration mechanism 35 includes an insulating mounting shell 351, to which the light-emitting optical fiber 33 and the photosensitive optical fiber 34 are fixedly connected on their sides by cables, a PCB board 352 is fixedly connected inside the insulating mounting shell 351, a filter chip 353 is fixed by soldering at the lower right front end of the PCB board 352, a feature extraction module 354 is fixed by soldering at the upper left front end of the PCB board 352, a difference information classifier 355 is fixed by soldering at the center of the front end of the PCB board 352, and a signal transmission module 356 is fixed by soldering at the lower left front end of the PCB board 352.

[0027] A through groove for installing the light-emitting optical fiber 33 and the photosensitive optical fiber 34 is arranged inside the gel interlayer 32, a detection area 321 is arranged on the middle side of the gel interlayer 32, and the through groove arranged at the detection area 321 is an interpenetrating structure; the front and rear sides of the detection area 321 of the gel interlayer 32 are penetrated and fixedly connected with the vertical fibers of the fiber fabric 31; the inner wall of the channel of the gel interlayer 32 is a fine conical structure aerogel material, and the aerogel material contains an ultraviolet light absorbing layer. Example

[0028] See also Figure 1~Figure 4, a pain intelligent feedback system with pressure recognition of the present invention, compared with the first embodiment, this embodiment also includes: an internal pressure recognition mechanism 4 includes an elastic bracket 41 fixedly connected to the inner wall of the fabric of the doll body 1; the first low-resistance conductive layer 42 and the second low-resistance conductive layer 43 are fixedly arranged on the inner and outer sides of the elastic bracket 41 respectively; a flexible substrate 44 with a protective function is fixedly arranged on the outer side of the second low-resistance conductive layer 43; a flexible circuit board 45 is fixedly connected to the inner side of the first low-resistance conductive layer 42; an electrode point 46 is fixedly arranged on the outer side of the flexible circuit board 45; a conductive coating is applied on the first low-resistance conductive layer 42 and the second low-resistance conductive layer 43, and a conductive path is formed between the first low-resistance conductive layer 42 and the electrode point 46 of the flexible circuit board 45 to generate a position recognition signal; a data integration mechanism 35 with data output is arranged on the side of the internal pressure recognition mechanism 4 through a cable.

[0029] The working principle of the pain intelligent feedback system with pressure recognition based on the above is:

[0030] First, when using the device, first place the device in the working area, and then connect the signal transmission module 356 in the data integration mechanism 35 in the device to the control terminal at the external doctor, so as to form a data sensing communication structure between the signal source of the doll body 1 and the terminal at the doctor;

[0031] Second, when the patient wants to express which part of the body feels pain / itching, he touches the corresponding part of the doll body 1. When the surface of the doll body 1 is squeezed, the fiber fabric 31 and the gel interlayer 32 are both deformed by external force. The gel interlayer 32 is deformed to reduce the internal channel of the detection area 321. Then, the cable outputs electrical energy to the light-emitting optical fiber 33, causing a photosensitive phenomenon between it and the photosensitive optical fiber 34. Since the inner wall of the channel of the detection area 321 is a fine conical structure aerogel material, and the aerogel material contains an ultraviolet light absorbing layer, part of the light power is incident on the ultraviolet light absorbing layer and escapes through the ultraviolet light absorbing layer, changing the photosensitive data of the photosensitive optical fiber 34. Since the fiber fabric 31 and the gel interlayer 32 are both soft materials, slight pressure can be detected without affecting the feel of the doll body 1.

[0032] Third, when the entire doll body 1 is squeezed, the flexible substrate 44 and the second low-resistance conductive layer 43 inside the doll body 1 are squeezed and contact the first low-resistance conductive layer 42. Since the electrode point 46 on the flexible circuit board 45 receives the constant voltage excitation from the cable connected to the first low-resistance conductive layer 42, a stable potential distribution is first formed on the first low-resistance conductive layer 42. The potential data of the first low-resistance conductive layer 42 is changed due to the approach of the second low-resistance conductive layer 43, and the measuring electrode on the flexible circuit board 45 generates a corresponding voltage signal, which is output to the control terminal via the data integration mechanism 35 connected to the flexible circuit board 45;

[0033] Fourth, the data signal of the photosensitive optical fiber 34 is transmitted to the filter chip 353 through a cable, and after the electric signal is filtered by the filter chip 353, the data feature is extracted by the feature extraction module 354, and the extracted data feature is compared with the standard value by the difference information classifier 355 to form a line graph, and then the signal transmission module 356 integrates and processes the collected data information and transmits it to the doctor's control terminal, and controls the display of the lamp tube assembly inside the toe 2 to display different colors according to the line graph data formed by the aforementioned difference information classifier 355, and expresses the grading of the degree of pain / itching according to the displayed color; at the same time, the doctor can more accurately display the pain / itching degree through the display end of the control terminal The pressure condition of the doll body 1 is accurately and real-time judged, and the touched area and part are automatically fed back to the doctor's terminal as the front / back / 3D image of the human figure according to the detection data, and the corresponding skin areas reflecting the pain are displayed in different colors for distinction, so as to realize the feedback of different pain / itching degrees of different parts in the three-dimensional image of the human figure by color; the spinal cord segment distribution, spinal nerve root distribution, and peripheral nerve innervation indicated by the skin area data here are automatically and intelligently analyzed and recorded in the doctor's terminal, and the dynamic curve of intelligent follow-up is combined with the display of the internal lamp tube component of the toe 2 to reflect the range and grading degree of pain / itching; it is recorded as a percentage of the body surface skin to reduce the risk of misjudgment of a single parameter.

[0034] The present invention provides an intelligent pain feedback system with pressure recognition through improvement. By setting a surface pressure recognition mechanism 3, the soft material of the fiber fabric 31 and the gel interlayer 32 can detect slight pressure without affecting the feel of the doll body 1, and part of the light power is incident on the ultraviolet light absorbing layer through the detection area 321 and escapes through the ultraviolet light absorbing layer, thereby changing the photosensitive data of the photosensitive optical fiber 34; by setting an internal pressure recognition mechanism 4, the measuring electrode is set inside the sensitive element, thereby improving the detection accuracy of the sensor in the entire sensitive area, and the flexible double-layer material combined with the elastic bracket 41 can be set into different shapes according to the shapes of various parts of the doll body 1, which has the advantages of flexibility, simple operation, easy production, low cost, high detection accuracy, etc. At the same time, the surface pressure recognition mechanism 3 and the internal pressure recognition mechanism 4 have intelligent analysis functions, data storage, and intelligent follow-up dynamic curves to reflect the range of pain / itching.
