Central authorities' control loop 1 is responsible for the whole device of master control, and it is connected with a power supply loop of voltage regulation 11, a show circuit 12, an input circuit 13, a function setting loop 14 and an interrupt circuitry 15 respectively.Wherein, power supply loop of voltage regulation 11 is connected in power supply input circuit 2, in order to be supplied to central control loop 1 after the input power supply V voltage stabilizing that power supply input circuit 2 is provided.The function that show circuit 12 provides image or picture and text, data, data etc. to show; Input circuit 13 provides the function of instruction input; Function setting loop 14 provide the pattern power of ultrasonic energy output, regularly, the memory set-up function; Interrupt circuitry 15 provides the function of every interruption timing.
Oscillation circuit 3 connects central control loop 1 via an oscillation switch loop 31, in order to the oscillator signal S that produces a sequence to output loop 4.Output loop 4 receives oscillator signal S, and via ultrasonic energy output probe 41 output ultrasonic wave energy.
Current detection circuit 5 through oscillation switch loop 31, oscillation circuit 3 is connected in output loop 4, and is connected in central control loop 1 via conversion of signals loop 51.Current detection circuit 5 is in order to the flow through current value A of output loop 4 of detection
N, and via delivering to central control loop 1 behind the conversion of signals loop 51 conversion generations one current state signal Fb.By this, constitute an intelligent detection loop 6, carry out detection safe in utilization by central control loop 1, interrupt circuitry 15, current detection circuit 5 and conversion of signals loop 51.
Consult shown in Figure 2ly, it is the control flow chart that shows first embodiment of the invention, and cooperates the 1st figure that the control flow of first embodiment of the invention is done one simultaneously to be described as follows.
At first, system start-up is by power supply input circuit 2 input power supply V (step 101).Before the beginning ultrasonic therapy, in system, determine required parameter earlier, these parameters include to be set current error scope Rt, setting-up time reference value T0 and sets working time higher limit Tw0 (step 102).These parameters are set except seeing through input circuit 13, also can be stored in the memorizer in advance.After setting is finished, start oscillation circuit 3, produce oscillator signal S to output loop 4, via ultrasonic energy output probe 41 output ultrasonic wave energy (step 103) by oscillation circuit 3.In this simultaneously, interrupt circuitry 15 picks up counting, the sampling work time T w (step 104) of sampling output ultrasonic wave energy.
After by ultrasonic energy output probe 41 output ultrasonic wave energy, at first carry out the detection of load, detect ultrasonic energy output probe 41 and whether be contacted with skin surface (step 105).When practical application, can see through the current value A that current detection circuit 5 detects the output loop 4 of flowing through
NVariation, judge whether ultrasonic energy output probe 41 is contacted with skin surface.Because ultrasonic energy output probe 41 situations that are contacted with skin surface and are not contacted with skin surface, can make the current value A that detects gained
NPresent variation, utilize this principle can learn promptly whether ultrasonic energy output probe 41 is contacted with skin surface.In addition, because when Supersonic head 41 (is not contacted with skin surface) under non-loaded situation, energy can produce high temperature because of can't loose to remove, so can utilize the mode of temperature detection, judge by the temperature that detects ultrasonic energy output probe 41 whether ultrasonic energy output probe 41 is contacted with skin surface.
When detecting ultrasonic energy output probe 41 when not being contacted with skin surface, then make ultrasonic energy output probe 41 stop or suspending the output ultrasonic wave energy, on implementing, it can produce control signal S0 to oscillation switch loop 31 by central control loop 1, make oscillation switch loop 31 become open-circuit condition, and then close oscillation circuit 3, make ultrasonic energy output probe 41 stop or suspending the output ultrasonic wave energy.Certainly, can also directly cut off the electricity supply input power supply V that input circuit 2 provided stops or suspending the output of ultrasonic energy.

N(step 106) then judges the current value A that is detected
NVariation whether maintain and set in the current error scope Rt (step 107).
Ultrasonic treatment unit 100 is in oscillatory work, and in the time of the output ultrasonic wave energy, the variation of load can cause current value A
NVery large-scale variation is arranged.According to this principle, thus in system default settings current error scope Rt as desired value, if the current value A that detects
NVariation when exceeding this and setting current error scope Rt, expression current value A
NExcursion enough big, just ultrasonic energy output probe 41 remains on and moves or sliding mode.If the current value A that detects
NVariation maintain when setting in the current error scope Rt, just represent that also ultrasonic energy output probe 41 may not move or slide, and the Long contact time same place.
In the present embodiment, judge the current value A that is detected
NVariation whether maintain and set the current value A that system is relatively detected earlier in the current error scope Rt
NWith the current value A that last time sampling time point detected
N-1, obtain current change quantity Δ A
N(step 107a) judges current change quantity Δ A again
NWhether less than setting current error scope Rt (step 107b).Utilization can be got rid of the error that parameter caused that some can be subjected to time effects with the mode that the present sampling time point and the sampling result of sampling time point last time compare, and it is more accurate to make on judging.In addition, set current error scope Rt, outside judging by central control loop 1, can also utilize conversion of signals loop 51 in conversion of signals, utilize the circuit design in conversion of signals loop 51 itself, current value A except being set in the central control loop 1
NVariation compare with setting current error scope Rt, the current state signal Fb with its back coupling is sent to central control loop 1 then, carries out follow-up judgement.
As the current value A that detects
NVariation exceed when setting current error scope Rt and (remain on and move or sliding mode), judge then whether the sampling work time T w that previous ultrasonic energy of having been taken a sample by interrupt circuitry 15 is exported probe 41 output ultrasonic wave energy arrives a predetermined setting working time higher limit (step 108), and when the sampling work time T w that judges ultrasonic energy output probe 41 output ultrasonic wave energy arrives setting working time higher limit Tw0, make ultrasonic energy output probe 41 stop or suspending the output ultrasonic wave energy, long and cause unexpected generation to avoid the working time.On implementing, it can close oscillation circuit 3, the input power supply V that the input circuit 2 of can also directly cutting off the electricity supply is provided by central control loop 1 control equally.
As the current value A that detects
NVariation maintain when setting in the current error scope Rt (move or slide), then judge current value A
NVariation maintain the sampling of setting in the current error scope Rt T that holds time and whether exceed setting-up time reference value T0 (step 109).It is implemented can be by interrupt circuitry 15 sampling (step 109a) of T of holding time of taking a sample, and judge by central control loop 1 whether the sampling T that holds time exceeds setting-up time reference value T0 (step 109b), to hold time T when surpassing setting-up time reference value T0 judging sampling, make ultrasonic energy output probe 41 stop or suspending output ultrasonic wave energy (step 110), avoid ultrasonic energy output probe 41 Long contact time same place, make the ultrasonic energy accumulation and damage.Can close oscillation circuit 3, the input power supply V that the input circuit 2 of can also directly cutting off the electricity supply is provided by central control loop 1 control equally in the enforcement.
Consult shown in Figure 3, it is the control flow chart that shows second embodiment of the invention, the step of this embodiment is identical with aforementioned first embodiment haply, so identical member is to indicate to number with components identical, its difference is to save and detects the step whether ultrasonic energy output probe 41 is contacted with skin surface, directly carries out follow-up mobile or slip and detects action.
