Example 5
The invention discloses an application of a quantitative superficial sensation comprehensive analysis early warning system, which comprises the following steps: the subject in this embodiment may be skin, or other object.
Firstly, the test of the skin is specifically explained:
1. the specific testing steps are as follows:
(1) the probe was set to the temperature varying mode by the PC10 and the test initial temperature was set to 30-32 ℃ (no cold or heat was felt by contact for several seconds in this temperature) and then transmitted to the microprocessor 9;
(2) after the microprocessor 9 receives the temperature change instruction, the microprocessor 9 changes the temperature of the contact surface of the temperature change device 4 (semiconductor refrigeration sheet) and the heat conduction spring 13 through the temperature control relay 6, and then the temperature is conducted to the infrared silicon lens 11 through the heat conduction spring 13, so that the temperature change of the infrared silicon lens 11 is realized within-5-50 ℃; the temperature of the infrared silicon lens 1 is monitored in real time through a temperature detection device 7 (a thermistor), and the monitored temperature is transmitted to a microprocessor 9;
(3) the upper limit and the lower limit of the safe skin temperature are set to 44 ℃ and 10.8 ℃ through PC10, the skin is detected through an infrared silicon lens of a probe, and an infrared temperature sensor 1 detects the skin temperature through an infrared silicon lens 11 and transmits the detected temperature to a microprocessor 9; the microprocessor 9 transmits the data detected by the temperature detection device 7 and the infrared temperature sensor 1 to the PC10 for data storage, data analysis and filing;
(4) when the skin temperature reaches a threshold value, an acousto-optic alarm device in the PC10 sends out early warning to remind the user of paying attention for 30 s; when the infrared temperature sensor 1 detects that the accumulated temperature of the measured object exceeds the warning temperature for more than 30s, the microprocessor 9 sends out an alarm signal and automatically changes the voltage at the two ends of the temperature changing device 4 to carry out a cold and heat source rewarming mode, so that the skin temperature returns to a safer temperature range of 30-32 ℃; the speed of the temperature rise and the speed of the temperature fall of the infrared silicon lens are 1 ℃/s;
the sequence is that firstly the cold threshold is measured by the infrared temperature sensor, then the cold pain threshold is measured, after 5 minutes, the initial temperature of the monitored skin is the same as that before monitoring, the measurement of the hot threshold and the hot pain threshold is carried out (considering that the peripheral sensation is not sensitive to the cold stimulus, the use of the process can reduce the sensitivity to the cold sensation after the thermal stimulus is carried out to the maximum extent, in addition, the influence of the cold perception state on the hot perception state is avoided at proper time intervals, thereby improving the measurement precision)
(5) When the invention is used, the invention is controlled by a dual control system (namely, automatic control by components such as a sensor, a microprocessor and the like and manual control by a mouse), when the threshold values of cold, heat, cold pain and hot pain are measured, a patient clicks a button by using the mouse, and the accumulated skin temperature, the heat source temperature and the heating (refrigerating) time when the button is clicked are recorded. On the other hand, the pressure sensor attached to the probe can identify protective reactions (such as hand contraction reaction, at the moment, the pressure sensor can detect the movement of the infrared silicon lens) caused by cold pain and hot pain, and carries out signal conversion through the sensor and the microprocessor to record the accumulated temperature of the skin, the temperature of a heat source and the heating (refrigerating) time. The method greatly improves the accuracy of the threshold value of quantitative measurement (cold, hot, cold and hot pain) and the application range of people. When recording, the recording time is selected from the time before.
The invention quantitatively obtains an index capable of judging the self-protective capability of the skin, and determines the cumulative temperature and time of the skin when the skin is heated by a constant-temperature heating source (a milder heat source can not generate obvious protective reaction when contacting the skin), a thermal pain threshold value or the self-protective reaction (similar hand shortening reaction, at the moment, a pressure sensor can detect the movement of an infrared silicon lens) based on the hot plate experiment principle. The skin accumulated temperature is monitored in real time through the infrared temperature sensor, an early warning system with set upper limit and lower limit of skin safety temperature is established, and secondary damage to the skin caused by the detection process is prevented.
2. When the invention is tested, the initial temperature of the skin can be obtained quantitatively by combining the ninth method, the heat dissipation capability of the skin or peripheral nerve and blood vessel diseases can be judged comprehensively, and the method comprises the following specific steps:
1) equally dividing the detected skin part into 9 areas, measuring the skin temperature of the skin of a target area, recording the temperature of each area by using a PC (personal computer), repeatedly measuring each area, automatically carrying out rank sum test by using a microprocessor according to 9 numerical values measured by the two areas, and judging whether the skin temperature is normal or not;
2) measuring the skin temperature of the skin of the corresponding healthy area on the healthy skin on the opposite side or around the detected skin part in the same way, and recording the temperature of each area by using a PC (personal computer), wherein each area can be repeatedly measured;
the two steps are completed, the PC automatically performs rank sum check on the 9 values measured in the two areas recorded in the two steps, and if the two values have statistical difference, the PC performs comprehensive judgment by combining other clinical indexes;
if the local skin temperature is higher, the skin may have the pathological changes of hypofunction of heat dissipation (hypofunction of sweat glands) or local skin inflammation and the like; if the local skin temperature is low, it is suspected to be related to peripheral vascular disease and peripheral nerve dysfunction.
And the progress of the disease or the effectiveness of the treatment is analyzed synthetically by recording at different times and keeping a record of the skin temperature.
3. After the microprocessor of the present invention transmits the data to the PC, the PC saves the data, forms an archive for individual patients and can combine L OESS model, analyze the course of disease change of the patient, and automatically combine the obtained data with rank test (rank sum test and kruscal willis test) to perform statistical test.
The system of the invention can obtain the accumulated skin temperature when various thresholds are generated on the basis of improving the accuracy of the measured threshold (cold, hot, cold pain and hot pain). In addition, the temperature probe can be adjusted to be constant at 47 +/-3 ℃ and 0 +/-3 ℃, the time required for protective reaction or thermal pain and the accumulated temperature of the skin are measured, the index capable of judging the self-protective performance of the skin is obtained quantitatively, and the comprehensive analysis can be carried out by combining the measured (cold, heat, cold pain and thermal pain) threshold value result through the index, so that whether the self-peripheral superficial sensation (pain and temperature sensation) is abnormal or not and the abnormal weight are judged and identified quantitatively. In addition, due to the real-time temperature detection early warning system and the intelligent rewarming system, skin damage to a subject caused by detection can be avoided. The determined crowd with peripheral superficial paresthesia can set the skin safety temperature in advance when some heat treatment or cold treatment (such as hip bath) is carried out, and monitor the skin accumulated temperature in real time, and can protect and early warn the skin safety of the crowd by alarming when reaching the safety threshold. The infrared silicon lens and the infrared temperature sensor can quantitatively measure the skin temperature of the skin at a specific position, and can comprehensively judge the heat dissipation capacity of the skin by combining with sweat gland function detection. Therefore, the system plays an important role in diagnosis, identification, adjuvant therapy and long-term monitoring of diseases.
Secondly, the quantitative superficial sensation comprehensive analysis early warning system is used as a heat source or a cold source and becomes auxiliary medical equipment for thermal therapy or cold therapy: the probe is set to be in a constant temperature mode through the PC, and the microprocessor controls the voltage applied to two ends of the semiconductor refrigeration piece after receiving the instruction to control the temperature of the temperature changing device, so that the temperature of the infrared silicon lens is fixed at 47 +/-3 ℃ or 0 +/-3 ℃ and is used as a heat source or a cold source; can be used as auxiliary medical equipment in the thermal therapy or cold therapy process to realize the skin safety protection of people with peripheral superficial feeling hypoesthesia, dullness or disappearance.
1) When the population is treated by heat therapy or cold therapy, the probe is fixed above the skin to detect the patient;
2) the upper limit of the safe skin temperature is set to be 44 ℃ and the lower limit is set to be 10.8 ℃, so that the thermal therapy or the cold therapy is adopted, the early warning is carried out when the accumulated skin temperature exceeds the set warning temperature, the mode of rewarming is automatically changed when the duration time is more than 30s, and the skin temperature damage caused by the therapy is prevented.
If the skin temperature is normal, the probe temperature is fixed at 47 +/-3 ℃, and the time and the skin accumulated temperature for the skin to generate the thermal pain and the protective reaction are recorded. When the skin accumulated temperature exceeds the set warning temperature, early warning is carried out, the mode is automatically changed into the rewarming mode when the duration time is more than 30s, and skin temperature damage caused by treatment is prevented.
The quantitative superficial sensory comprehensive analysis early warning system is used as an instrument for measuring nerve conduction: the nerve conduction of animals can be measured in animal experiments, and the animal does not have the autonomous consciousness to record thermal pain, cold pain and the like passing through the system, so that the pressure sensor records multiple indexes of time of protective reaction (foot contraction reaction), heat source temperature and skin accumulated temperature, and the peripheral nerve conduction condition of the animal is quantitatively analyzed.
