Because tumor thermotherapy is a kind of application thermal source carries out warming therapeutic method to malignant tumor, this utility model in use, heater and temperature measuring equipment all near and act on pathological changes body, so with regard to thermotherapy itself, it is a kind of pure physical property treatment, the organizational structure that its concrete principle is just tumor self is unsound, heat radiation compared with normal tissue is slow, make tumor temperature compared with normal tissue exceed 5 DEG C～10 DEG C, and malignant cell is thermo-responsive to height, result is that after high heat, tumor cell is killed or apoptosis gradually, and normal structure is injury-free.
This device utilizes the output of single-chip microcomputer level signal control heater to change, by temperature sensor, experience the situation of change of pathological changes organism temperature, again measured temperature value is sent to single-chip microcomputer, utilize single-chip microcomputer internal processes to compare and revise, ensure stability and the adjustability of pathological changes organism temperature.Due to the inner integrated A/D conversion of single-chip microcomputer and data storage cell, simplify to a great extent conventional peripheral redundant circuit.Being used in conjunction with of temperature sensor and discharge circuit, can improve certainty of measurement, boostfiltering effect, thus effectively avoid and reduce the interference of electromagnetism clutter to therapeutic process.
Because device is taking low-consumption wireless single-chip microcomputer as core, so wireless interconnected by signal control device and signal receiving device, can realize the real-time demonstration to therapeutic state, the real-time preservation of overtemperature early warning and data, the seriality that ensures data with can comparative, misdescription or error of omission while avoiding manual record treatment data, while being particularly useful for treating studying for a long period of time property of patient, the complete preservation for the treatment of data can help to set up the discrete domain of pointed fuzzy control, more common PID Temp. control method safety and reliability, there is very high clinical value, can more effectively improve medical worker's work efficiency and accuracy rate.
Brief description of the drawings
Fig. 1 is composition structure chart of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of mode of wireless transmission tumor thermotherapy device, the heater 2 that comprises signal control device 1 and be connected respectively with it, temperature measuring equipment 3 and signal receiving device, signal control device 1 and signal receiving device are by wireless connections, heater 2 interconnects with temperature measuring equipment 3, signal control device 1 includes wireless receiving and dispatching formula singlechip chip 4 with signal receiving device, temperature measuring equipment 3 by temperature sensor 5 and connect discharge circuit and form, heater 2 comprises electric radiation plate or microwave applicator, signal receiving device also comprises data storage 8 and display alarm unit 9.
This utility model is in the time designing and producing, and singlechip chip can be selected NRF9E5 type single-chip microcomputer, not only has radio transmission-receiving function, also built-in A/D module and data storage cell; Temperature sensor can be selected platinum resistance formula or thermistor-type, the former selects PT100 series conventionally, the latter mostly is negative temperature coefficient, select semi-conducting material, volume is little, also fast to the response of variations in temperature, is quick on the draw, there is good precision, so be particularly applicable to the control application scenario that needs carry out fast and smart temperature is measured; Selected discharge circuit, comprise two parts, a part is signal amplifier 6, i.e. common mode disturbances inhibition type differential amplifier circuit, the outer optionally connected slide rheostat of amplifying circuit, can realize the adjusting of amplification, for the processing to output signal, another part is band filter 7, comprises bandwidth-limited circuit, can be used for boostfiltering effect, thereby effectively avoid and reduce the interference of electromagnetism clutter to therapeutic process.
This device utilizes the output of single-chip microcomputer level signal control heater to change, taking heating element heater as electric radiation plate is as example, it is taking electricity as the energy, electrical heating elements raises working surface temperature by conduction pattern, working surface in infrared emanation mode to radiant in space, people in space and object absorb heat, reach intensification effect, the built-in heater element of electric radiation plate is not luminous, not oxygen consumption, the flames of anger, heat its working surface, as aluminium alloy face, working surface is emitted infrared ray and in space, is carried out heat radiation, utilize the level signal of single-chip microcomputer output, control the size of heating output power adjustable, heating comprises rustless steel armouring electrothermal tube or heating wire, electric heating cloth etc., electric thermal power is generally 500W～5000W, if when heating element heater is microwave applicator, level signal control microwave frequency, heating is from interior of articles, and homogeneous heating, has the features such as firing rate is fast, thermal loss is little, easy to operate.
Research shows, 42 DEG C in vitro, continue within 120 minutes, to carry out thermotherapy, and can make the cancer effect of going out of some chemotherapeutics strengthen 10～100 times.In clinical practice application, thermotherapy and chemotherapy combined application, its curative effect is far longer than the addition of two kinds of curative effects.In the situation that reaching same curative effect index, chemotherapeutics consumption just can reduce, thereby has reduced the harm to human body.Taking design temperature as 42 DEG C as example, after heater starts, by temperature sensor, experience the situation of change of pathological changes organism temperature, then measured temperature value is sent to single-chip microcomputer, because the temperature of pathological changes body is real-time change, institute thinks maintenance steady temperature, need to utilize single-chip microcomputer internal processes to compare and revise, regulate the output of heater, ensure stability and the adjustability of pathological changes organism temperature.
Wireless singlechip built-in linear A/D converter, can pass through the time of software set sampling adjustment, carries out start/stop pattern, is digital signal to be sent by date processing after conversion.Taking wireless singlechip NRF9E5 as example, it the is built-in 433MHz of NRF905,868MHz, 915MHz transceiver, makes can complete the functions such as wireless transmission, reception and monitoring between single-chip microcomputer.Real-time data transmission to be sent is given and is received after single-chip microcomputer, and on the one hand, data can show in real time in display alarm unit, or carry out overload alarm, and on the other hand, data are stored in data storage EEPROM automatically, edit and call for data base.Wherein, data storage is connected with the general purpose I/O pin that receives single-chip microcomputer NRF9E5 by IIC interface bus, realizes data interconnection.The continuous preservation for the treatment of data has ensured data base's integrity, can help to set up the discrete domain of pointed fuzzy control, in actual mechanical process, first obtain the accurate amount of current information, contrast a large amount of practical data experiences, by its obfuscation, how analyze judgement reply input quantity adjusts, make fuzzy decision, again fuzzy decision is converted into the accurate amount of input, go to control concrete operation, if fuzzy control is applied among thermotherapy temperature control, PID Temp. control method safety and reliability that will be more common, there is very high clinical value, can more effectively improve medical worker's work efficiency and accuracy rate.
