Human body sensory checkout gear based on thermal stimulus
Technical field
This utility model relates to a kind of sensation checkout gear, specifically, relates to a kind of human body sensory checkout gear based on thermal stimulus.
Background technology
Sensory recovery program is absolutely necessary the patient that sensation rehabilitation training loses sensibility or all loses sensibility for body part.Utilize rehabilitation training equipment to carry out systematic training to the out of the count limb part of patient, thereby patient's sensation is progressively recovered be comparatively conventional rehabilitation mode at present.Yet, often volume is larger for existing sensation rehabilitation training equipment, for example, for patient's part (wrist, shank, back, waist) with it, can not carry out effective sense culture, this has also caused training effect cannot reach best, and sensory recovery is slow.And existing rehabilitation training equipment is all to carry out manual detection by professional medical personnel conventionally when judgement rehabilitation situation, judgement by rule of thumb, very trouble, not directly perceived yet, entirely with working experience, substantially assesses, and is also easy to occur error.
Utility model content
The purpose of this utility model is to provide a kind of human body sensory checkout gear based on thermal stimulus, for rehabilitation training provides intuitively, thermoesthesia detects and shows effectively, thereby for medical personnel judge rehabilitation situation, provide accurate foundation, solve the defect that error easily appears in the judgement by rule of thumb existing in prior art.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Human body sensory checkout gear based on thermal stimulus, comprise for being tied to carrier on human body, be arranged on this carrier inside protective pad, be fixed on the cold and hot transducer mount on this protective pad, and be fixed on this protective pad the temperature sensor for detection of carrier inside temperature, and be positioned on described carrier outer surface and the display unit being electrically connected to this temperature sensor.
Preferably, described carrier is bandage.
Further, display unit comprises the display screen that is arranged on described bandage outer surface, with the amplifier being connected with described temperature sensor, the wave filter being connected with this amplifier, and the central processing unit being connected with display screen with this wave filter respectively.
Again further, described cold and hot transducer mount comprises heating wire and the semiconductor chilling plate being arranged on protective pad, and the control circuit being electrically connected to this heating wire and semiconductor chilling plate, this control circuit comprises power supply, gauge tap, variable resistance and electric fuse, wherein, described variable resistance, electric fuse, heating wire, semiconductor chilling plate and gauge tap are connected to form loop with described power supply after mutually connecting.
Further, described power supply, gauge tap, variable resistance and electric fuse are all arranged at the outer surface of described bandage.
Compared with prior art, the utlity model has following beneficial effect:
(1) this utility model design is ingenious, simple in structure, during use, only bandage need to be tied on people's limbs, makes inner protective pad be close to human body skin, very convenient.
(2) this utility model is by regulating variable resistance to change the size of current in circuit, thereby make heating wire and semiconductor chilling plate produce different caloric stimulations, utilize temperature sensor to detect Current Temperatures simultaneously, and show, so patient can be carried out directly detecting and showing to the perception of temperature, thereby for medical personnel provide basis for estimation accurately, avoid the error that occurs by micro-judgment, for solid foundation is established in patient's follow-up rehabilitation training.
(3) this utility model is installed in the equipment such as the gauge tap of display screen and circuit, power supply the outside of bandage, so can be patient's operation great convenience is provided.
(4) this utility model is fixed on cold and hot transducer mount on human body skin by bandage; both for cold and hot transducer mount provides fixing carrier; also for human body provides supercool or overtemperature protection, avoid too high or too low for temperature human body skin is damaged, kill two birds with one stone.
(5) electric fuse that this utility model arranges in circuit is the voltage in control circuit effectively, prevents from that voltage is excessive human body is damaged, thereby provide reliable safety guarantee for human body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
1-bandage, 2-protective pad, 3-heating wire, 4-semiconductor chilling plate, 5-temperature sensor.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the human body sensory checkout gear based on thermal stimulus, mainly comprises the carrier being formed by bandage 1, is arranged on the protective pad 2 of bandage inside, cold and hot transducer mount, temperature sensor 5, and the display screen and the control circuit that are positioned at bandage outside.
Specifically, cold and hot transducer mount is fixed on protective pad, comprises heating wire 3 and semiconductor chilling plate 4, and they are connected with power supply after connecting with gauge tap, electric fuse, the variable resistance of bandage outside, and power supply is generally used 5V or 12V power supply.By regulating variable-resistance size to change the size of current in circuit, thus the stimulation that makes heating wire or semiconductor chilling plate produce different temperatures, to detect the perception of patient to cold and hot temperature.Meanwhile, the real-time detected temperatures of temperature sensor, and carry out, after signal processing, being presented on the display screen of bandage outside through amplifier, wave filter.When a certain moment patient represents to have felt caloric stimulation, the temperature that now shows screen display is patient's perception to temperature in during rehabilitation training, the temperature that medical personnel can show according to display screen directly judges whether patient recovers the perception to temperature completely, without relying on micro-judgment, accurately, conveniently.
This utility model is all arranged on power supply, electric fuse, variable resistance, gauge tap the outside of bandage, can directly be fixed on bandage outer surface, also can design separately an operation panel, does not limit herein.So design not only can facilitate patient to operate this device, and also the later maintenance for equipment provides convenience, kills two birds with one stone.
Above-described embodiment is only preferred embodiment of the present utility model; the not restriction to this utility model protection domain; in every case adopt design principle of the present utility model, and carry out non-creativeness work on this basis and the variation made, within all should belonging to protection domain of the present utility model.
