The present invention proposes and apply the technology of above-mentioned several improvement limbs pressurization physiotherapy table design.Relate to the electrical equipment of naturopathy.Comprise: 1 pressure transducer.2 single-chip microcomputers.3 touch display screens.4EEPROM。5 air pumps.6 pressure retaining valves.7 gas circuit valves.8 overvoltage protection valves.9 independent overvoltage protective modules.10 connecting lines.11 air bags.Be further described below:
1 pressure transducer.Adopt the pressure transducer MPX5050 that REESCALE company of the U.S. produces.Convert the gas pressure being added to air bag to the signal of telecommunication.
2 single-chip microcomputers.The C8051F02X series SOC(system on a chip) (SOC adopting SL company of the U.S. to produce; System On Chip) single-chip microcomputer controls equipment and carries out overvoltage protection; it is powerful, includes 12 ADC and carries out process acquisition force value to the signal of telecommunication that pressure transducer is brought.
3 touch display screens.The 8 inch TFT intelligence color touch display screen HMT080EA-C adopting Shenzhen Tuo Puwei company to produce, can show treatment situation in real time with animation and provide man-machine conversation interface.
4EEPROM。For storing and calling prescription
5 air pumps.Air bag is carried out pneumatic compression.Controlled by enhancement mode zero cross fired solid-state relay.
6 pressure retaining valves.Carry out pneumatic compression when opening, during closedown, carry out pressurize.
7 gas circuit valves.Receive pressure retaining valve when pressurization and pressurize, during release of pressure, receive air.
8 overvoltage protection valves.Pressure exceedes equipment setting and will exit.
9 independent overvoltage protective modules.Pressure exceedes equipment setting and will exit.Break down in control system and also can normally work.
10 connecting lines.Connection device and air bag.
11 air bags.Conventional lower limb air bag and upper limb body air bag, 2,4,8 chambeies are more conventional.Be used for the treatment of.
The specific embodiment of the present invention is:
The treatment prescription of 1 various ways stores and calling technology.Design is specifically designed to the EEPROM of the memory capacity 256KBIT that treatment prescription stores and calls, once edit conventional prescription and carried out storing just need not compile again calling at any time later, usual editor prescription needs button tens of time, and calls a prescription and only need button 3 times.
The treatment prescription of various ways stores and calling technology refers to that user one of three kinds of modes below choice for use can carry out the start Automatically invoked for the treatment of prescription: the treatment prescription calling last use before shutdown; The start treatment prescription of invocation facility acquiescence; Other prescription stored by equipment and user that invoke user is specified, therefore just can be called in prescription without the need to depresses button after start automatically.
Make prescription editor both can use online edit pattern that the treatment prescription of various ways also can be used to store and calling technology after improvement, equipment use is more convenient.
The order of the inflation/deflation of each air bag, being stored in the control method that the control sequence in EEPROM relates to is prior art, if called in the storage of EEPROM, and in multiple prescription, selecting a method run, is all that those skilled in the art are normally used.
2 adopt AC air pump.Adopt the 220V AC air pump KPT38A that Xiamen company of section produces, domestic direct current air pump the reason life-span such as constantly to wear and tear less than 1000 hours due to carbon brush and rotor, and the domestic AC air pump life-span selected can reach 3000 hours, and AC air pump is with the obvious advantage.
3 enhancement mode zero cross fired solid-state relays carry out AC air pump control technology: alternating current generator uses 220V alternating voltage, audion can not be used to control, because the motor that acts frequently is again that inductive load uses relay, bidirectional triode thyristor, plain edition solid-state relay all easily damages, and enhancement mode zero cross fired solid-state relay can blocking voltage high, can tolerate higher dv/dt, it is optimum selection that appropriate bands inductive load uses enhancement mode zero cross fired solid-state relay to carry out AC air pump control technology.
4 low-power consumption standby technology: due to often holding state can be in after device power-up; electromagnetic valve is the element that in equipment, power consumption is maximum; the configuration of rational gas circuit valve, pressure retaining valve, overvoltage protection valve electromagnetic valve is have selected in design process; be respectively 23 usual valve closing, 22 usual valve closing, 22 usual valve opening; all electromagnetic valve all power-off under the prerequisite of air all received by whole air bag by guarantee safety when such performance configuration makes holding state, now Overall Power Consumption drops to 20% of rated disspation.
5 independent overvoltage protective module technology: control system inherently has over-voltage protecting function; devise independent overvoltage protective module simultaneously; it includes independently pressure transducer MPX5050, comparator LM311, depositor CD4013, driver ULN2066B and independently overvoltage protection valve; even if also can complete independently overvoltage protection task when control system breaks down, substantially increase the safety of equipment.
Suppose that the probability that the over-voltage protecting function that control system inherently has breaks down is P (A)=10
-6, the probability that independent overvoltage protective module occurs is P (B)=10
-7, be P (AB) according to the probability that these two independent events of theory of probability break down simultaneously;
P(AB)＝P(A)*P(B)＝10
-13
Visual security improves greatly.Above-mentioned described control method is prior art.
6 two-stage self-checkings: two-stage self-checking is respectively printed panel level and device level self-check program composition, and whether the master control plated circuit that printed panel level self-check program is used for checkout equipment is normal; Device level self-check program is used for equipment pressure calibration test and the test of automatic leakage air rate, can rapid automation checkout equipment whether normal, thus make equipment quality be able to dual guarantee.
