Description
Technical field
The present invention relates to a kind of vertebral body tractive bed, particularly relate to a kind of control method of automatic vertebral body tractive bed.
Background technology
The programming Control circuit of micro computer vertebral body tractive bed is made up of main circuit board and control circuit plate two part now, main circuit board runs for controlling electric pushrod, control circuit plate is connected with main circuit board, control circuit plate is for inputting operational factor, control circuit plate arranges thin film switch or silica gel push-button formation manipulation screen, manipulation screen is provided with sign name and is called setting, + 1,-1, run, stop, enter, move back, the button such as neck and waist, operation screen is also provided with a display screen, traction force can be shown, cycle-index, the tractive time, the operational factors such as off time.Be provided with force transducer in the control system of micro computer vertebral body tractive bed now, when motor runs, traction force that user vertebral body bears can be detected in real time and display on a display screen.During use, user can set 4 parameters such as traction force, tractive time, off time, cycle-index on manipulation screen, when setting traction force parameter, one or subtract an operation and be adjusted to desired value can be added to traction force, add one that is tractive force value increase by one kilogram, subtract one that is tractive force value reduce one kilogram.After starting, the parameter according to setting is run by tractive bed automatically, in a pull-pull cycles, when traction force reaches setting value electric pushrod by out of service and traction force is maintained one setting the tractive time, at the end of the timing of tractive time, electric pushrod is discharged toward the traction force that rollback makes human body bear and is maintained an off time, at the end of timing off time system will enter next time pull-pull cycles until EP (end of program).
Micro computer vertebral body tractive bed uses step to generally include tensile test step, Parameter setting step, automatic pull step now.
Tensile test step comprises the value of thrust that method testing human vertebral body manually can bear;
Parameter setting step comprises the operational factors such as setting traction force, tractive time, off time, cycle-index.In this step, corresponding patient can be marked for different operational factors, and by operational factor storage in systems in which, when different patients uses, my the direct startup optimization of operational factor applicable can be recalled.In existing tractive bed, tractive unit of force is kilogram, the unit of tractive time be second or minute, the unit of off time be second or point kind.In setting procedure, to be set as example to the tractive time, if unit is second, adding the tractive time set first increases by one second, subtracts the tractive time decreased that sets first one second.
Automatic pull step comprise automatically complete first time pull-pull cycles, automatically complete second time pull-pull cycles until complete last pull-pull cycles.Repeatedly pull-pull cycles can be comprised in an automatic running program, such as, if cycle-index is set as 4, then will comprise 4 pull-pull cycles in an automatic running program.After entering automatic running program, system will complete first time pull-pull cycles, second time pull-pull cycles successively automatically until complete last 4th pull-pull cycles.In pull-pull cycles process each time, system needs to carry out following process successively: 1st, motor advances, and traction force progressively increases, and when traction force reaches the parameter value of setting, motor halts and maintains value of thrust; 2nd, when motor maintains the value of thrust of setting, the tractive time starts to enter timing until timing terminates; 3rd, at the end of the timing of tractive time motor toward rollback and system enters timing off time until timing terminates; 4th, at the end of timing off time, this pull-pull cycles terminates, and system then enters pull-pull cycles next time.
Existing vertebral body broaching machine has two kinds of control modes, and the first needs to assist manipulation by doctor or nurse; The second is omnidistance by patient's autonomous operation, and disclosed in China Patent Publication No. 204219120U, 204428236U, vertebral body tractive bed belongs to the second control mode.In the first control mode, after patient lies on tractive bed, first doctor will fix fixing strap of waist and head harness for patient, and then operation manipulation screen starting device runs.Because tractive bed is manipulated by doctor, in tensile test step, manually tested by doctor and advance by key control motor, along with the progressively increase of pulling force, when pulling force arrives desired value, patient must halt Xiang doctor's feedback information so that doctor controls motor in time.In actual use, send information from patient and control motor to doctor and stop often there is the time difference, easy Yin Lali is excessive and pull accident, and this is a serious potential safety hazard of existing product existence.Therefore, in order to ensure the safety of testing procedure, in existing equipment, also independently arranging one stops button by the urgency of Patient controlled, and in case of emergency, patient can utilize and suddenly stop halting by key control motor, avoids Yin Lali excessive and injured.And in the second control mode, be that the operation of the fixing of traction belt or manipulation screen all has be by patient's autonomous operation.
For prior art, starting device runs automatically can following three kinds of approach, the first approach, manipulator can complete tensile test step, Parameter setting step successively, in Parameter setting step, 4 parameters such as traction force, tractive time, off time and cycle-index are set, then preserve operational factor starting device enters automatic running program; The second approach, manipulator can without testing procedure, and enter from setting procedure and to set operational factor and to preserve, then starting device runs automatically; The third approach, manipulator also can directly recall without test and setting two steps and select the direct starting device of suitable operational factor stored in systems in which to enter automatic running program on manipulation screen.
Problem is, in actual use, due in setting procedure, traction force parameter carries out plus-minus adjustment by manipulator by button, the problem gone wrong when this is with regard to occurring in unavoidably and carrying out data point reuse.On the other hand, even same patient, if the fixing position of fixing strap of waist is different or tightness is different, the pull strength size that when drawing, patient can bear is not identical yet.Therefore, traction force parameter is carried out testing by manipulator and in setting procedure, is carried out plus-minus adjustment and then to preserve and starting device runs automatically or without test and setting two steps and directly recall and select the operational factor starting device stored in systems in which automatically to run in testing procedure, all there is certain potential safety hazard in these methods, patient may be caused to be pulled.

Specific embodiment one
In the present embodiment, with reference to the manipulation screen key layout schematic diagram of Fig. 1, the control method of a kind of automatic vertebral body tractive bed that the present invention proposes comprises carries out following steps successively:
First, tensile test step: make system enter waist test pattern by waist button under initial state, in waist test pattern, advance or retrogressing by key control motor by entering or moving back, now display upper pulling force numerical value is the measured value that human body bears traction force, when human feeling is in suitable to traction force, the reference value that current pulling force sets as traction force is deposited in system automatically by waist button by long, make system enter waist set model simultaneously, under waist set model, display screen cocycle number of times, a parameter is had to be in blink states in three parameters such as tractive time and off time.
Under initial state, make system enter neck test pattern by neck button, in neck test pattern, advance or retrogressing by key control motor by entering or moving back, now display upper pulling force numerical value is the measured value that human body bears traction force, when human feeling is in suitable to traction force, the reference value that current pulling force sets as traction force is deposited in system automatically by neck button by long, make system enter neck set model simultaneously, under neck set model, display screen cocycle number of times, a parameter is had to be in blink states in three parameters such as tractive time and off time.
The second, Parameter setting step, under waist set model, only can adjust three parameters such as tractive time, off time, cycle-indexes, the parameter needing adjustment can be selected by setting button, often by setting button next time, next parameter will be glimmered, and then can carry out plus-minus adjustment by+1 or-1 adjustment key to this parameter when certain parameter on display screen is in blink states.Such as, when under waist set model, cycle-index is in blink states, plus-minus adjustment can be carried out to this parameter by+1 or-1 adjustment key, and then by once setting button, appearance flicker also can be carried out plus-minus adjustment by tractive time parameter, and then by once setting button, off time, appearance flicker also can be carried out plus-minus adjustment by parameter, if then again by once setting button, cycle-index parameter gets back to blink states once more, after parameter setting completes, by long ammonium setting button, operational factor is saved in system in system and enters waist automatic mode, system is only preserved when last group of operational factor, raw parameter is covered automatically, parameter now on display screen is no longer glimmered.
Under neck set model, only can adjust three parameters such as tractive time, off time, cycle-indexes, the parameter needing adjustment can be selected by setting button, often by setting button next time, next parameter will be glimmered, and then can carry out plus-minus adjustment by+1 or-1 adjustment key to this parameter when certain parameter on display screen is in blink states.Such as, when under neck set model, cycle-index is in blink states, plus-minus adjustment can be carried out to this parameter by+1 or-1 adjustment key, and then by once setting button, appearance flicker also can be carried out plus-minus adjustment by tractive time parameter, and then by once setting button, off time, appearance flicker also can be carried out plus-minus adjustment by parameter, if finally also want to get back to cycle-index setting, can again by once setting button, cycle-index parameter gets back to blink states once more, after parameter setting completes, by setting button, operational factor is saved in system in system by length and enters neck automatic mode, system is only preserved when last group of operational factor, raw parameter is covered automatically, parameter now on display screen is no longer glimmered.
Three, automatic pull step: under waist automatic mode, waist automatic running program is entered by running key system, system will complete first time pull-pull cycles, second time pull-pull cycles automatically until complete last pull-pull cycles, at the end of last pull-pull cycles, system automatically resets to initial state
Under neck automatic mode, neck automatic running program is entered by running key system, system completes first time pull-pull cycles, second time pull-pull cycles automatically until complete last pull-pull cycles, and at the end of last pull-pull cycles, system automatically resets to initial state
In the process of pull-pull cycles each time of an automatic running program, system needs to carry out following process successively: 1st, motor advances, and traction force progressively increases, and when traction force reaches the parameter value of setting, motor halts and maintains value of thrust; 2nd, when motor maintains the value of thrust of setting, the tractive time starts to enter timing until timing terminates; 3rd, at the end of the timing of tractive time, motor enters timing off time until timing terminates toward rollback simultaneity factor; 4th, at the end of timing off time, this pull-pull cycles terminates, and system then enters pull-pull cycles next time,
In this example, in third step, the traction force that system sets automatically in each pull-pull cycles of an automatic running program equals reference value.Such as, in a first step, if the suitable traction force of human feeling is 20KG in waist test, then the reference value that 20KG sets as traction force is deposited in system automatically by waist button by long; In third step, the traction force that system sets automatically in each pull-pull cycles of an automatic running program all equals 20KG.
In first, second or third step, if the chance state of emergency, system reset can be made to initial state by stopping key, and when system automatically resets to initial state, set reference value by the traction force that is saved in testing procedure in system will be automatically left out, system shows traction force measured value and only preserves the operational factor that last group comprises tractive time, off time, cycle-index.
On the basis of first embodiment technical characteristic, the present invention also proposes following preferred embodiment:
Another embodiment of the present invention, in third step, in each pull-pull cycles of an automatic running program, system sets that primary traction force equals that reference value subtracts 2KG automatically, secondary traction force equals that reference value subtracts 1KG, the traction force of third time and later each time equals reference value.Such as, in a first step, if the suitable traction force of human feeling is 20KG in waist test, then the reference value that 20KG sets as traction force is deposited in system automatically by waist button by long; In third step, in each pull-pull cycles of an automatic running program, system automatically sets primary traction force and equals that reference value 20KG subtracts 2KG and 18KG, secondary traction force equals reference value 20KG and subtracts 1KG and 19KG, and the traction force of third time and later each time equals reference value 20KG.In this example, in each circulation of automatic pull program, the traction force of first three times progressively increases, and then keeps identical from third time and later traction force.
Another embodiment of the present invention, the ultimate tension safety value of waist is set in 25KG-30KG by system, and the ultimate tension safety value of neck is set in 15KG-20KG.Therefore, in this example, with reference to Fig. 1, in a first step, under waist test pattern, advance by key control motor by entering, when sensor detects that the pulling force that human body lumbar vertebra bears reaches the waist safe limit value of default, motor will halt; In like manner, under neck test pattern, advance by key control motor by entering, when sensor detects that the pulling force that human cervical spine bears reaches the neck safe limit value of default, motor will halt.Because the advance of motor in test mode or retrogressing carry out Non-follow control by manipulator, setting safe limit value effectively can prevent human operational error, avoids pulling force to transship.Simultaneously, because the traction force setting reference value in operational factor in an automatic running program to be saved in system by button in testing procedure and can not to adjust in setting procedure subsequently, so system is in automatic running, the actual traction force of waist also controls naturally below the waist safe limit value of setting, the actual traction force of neck controls, below the neck safe limit value of setting, so just more effectively to guarantee the safe operation of equipment.In order to ensure safety, the ultimate tension safety value of system is cured in systems in which, and manipulator in use can not adjust safety value.
Another embodiment of the present invention, in a first step, waist test pattern and neck test pattern can be switched mutually by button.In this example, with reference to Fig. 1, under being in waist test pattern, can by systematic evaluation to neck test pattern by neck button, in like manner, under being in neck test pattern, can by systematic evaluation to waist test pattern by waist button.
Another embodiment of the present invention, in the second step, under waist set model, when operational factor is successfully protected to system, first then automatic rollback 1-2 time second enter waist automatic mode to motor; Under neck set model, when operational factor is successfully protected to system, first then automatic rollback 1-2 time second enter neck automatic mode to motor.
Another embodiment of the present invention, in third step, in the pull-pull cycles each time of an automatic running program, system is at the end of the tractive time, motor is automatic rollback 1-2 time second first, then system enters timing off time again, enter pull-pull cycles next time after timing terminates, at the end of last pull-pull cycles, system automatically resets to initial state.
Another embodiment of the present invention, in third step, when system enters automatic running program, when sensor data cable in system or control device data wire come off, system automatically resets to initial state.
From above-mentioned all embodiments, the control method of automatic vertebral body tractive bed that the present invention proposes has following technical characteristic: 1st, traction force in the testing procedure of the first step, is automatically kept at system by button and traction force parameter can not adjust in the setting procedure of second step.2nd, when system reset is to initial state each time, the former traction force setting reference value be saved in system will be automatically left out, and system now shows traction force measured value and only preserves last group tractive time, off time, cycle-index operational factor.This just to guarantee before entering automatic running program at every turn must first through tensile test and in setting procedure pulling force parameter can not adjust again, system stored in traction force setting reference value only effective to the automatic running program of subsequently, the potential safety hazard that prior art exists can be eliminated, effectively guarantee safety.The control method of automatic vertebral body tractive bed that the present invention proposes not only can be applied on the equipment that manipulated by doctor, is especially applicable to being applied on the equipment that independently manipulated by user.The vertebral body pulling equipment independently manipulated by user needs to possess higher security reliability, the control method of the automatic vertebral body tractive bed that the present invention proposes can meet the demands completely, be suitable in hospital clinic, drop into medical treatment to use, be particularly suitable for promoting the use of in family, health care costs in community unit.
