Description

Control method of automatic vertebral body pulling bed

Technical field

The invention relates to a vertebral body pulling bed, in particular to a method for controlling an automatic vertebral body pulling bed.

Background technique

The programming control circuit of the micro-computer vertebral body pulling bed is composed of a main circuit board and a control circuit board. The main circuit board is used to control the operation of the electric push rod, the control circuit board is connected with the main circuit board, and the control circuit board is used for input. Operation parameters, set the membrane switch or silicone button on the control circuit board to form the control panel, and set the buttons on the control panel with the name of setting, +1, -1, running, stop, advance, retreat, neck and waist. The operation screen is also provided with a display screen, which can display operating parameters such as pulling force, number of cycles, pulling time, and gap time. Nowadays, a force sensor is arranged in the control system of the micro-computer vertebral pull-up bed. When the motor is running, the pulling force of the user's vertebral body can be detected in real time and displayed on the display screen. When using, the user can set four parameters such as pulling force, pulling time, gap time and cycle number on the control panel. When setting the pulling force parameter, the pulling force can be increased by one or Subtract one operation to adjust it to the appropriate value, plus one, the pulling force value is increased by one kilogram, minus one, that is, the pulling force value is reduced by one kilogram. After starting, the pulling bed will automatically run according to the set parameters. In a pulling cycle, when the pulling force reaches the set value, the electric push rod will stop running and the pulling force will maintain a set pulling time. At the end of the pulling time, the electric push rod is retracted to release the pulling force of the human body and maintain a gap time. At the end of the gap time, the system will enter the next pulling cycle until the end of the program.

The current micro-computer vertebral traction bed use steps usually include a tensile test step, a parameter setting step, and an automatic pulling step.

The tensile test step includes testing the tensile force that the human vertebral body can withstand by a manual method;

The parameter setting steps include setting operating parameters such as pulling force, pulling time, gap time, and number of cycles. In this step, the corresponding disease number can be marked for different operating parameters, and the running parameters are stored in the system. When different patients use, they can call up the operating parameters suitable for the person to start the operation directly. In the existing pulling bed, the unit of pulling force is kilogram, the unit of pulling time is seconds or minutes, and the unit of gap time is second or minute. In the setting step, the pull time is set as an example. If the unit is seconds, the set pull time is increased by one second, and the set pull time is decreased by one second.

The automatic pulling step includes automatically completing the first pulling cycle, automatically completing the second pulling cycle, and completing the last pulling cycle. An automatic running program can include multiple pulling cycles. For example, if the number of cycles is set to 4, an automatic running program will include 4 pulling cycles. After entering the automatic running program, the system will automatically complete the first pulling cycle and the second pulling cycle in sequence until the last fourth pulling cycle is completed. During each pulling cycle, the system needs to perform the following processes in sequence: first, the motor advances, the pulling force is gradually increased, and when the pulling force reaches the set parameter value, the motor stops advancing and maintains the tensile value; 2. When the motor maintains the set tension value, the pulling time begins to enter the timing until the end of the timing; 3, when the pulling time is over, the motor retreats and the system enters the gap time until the timing ends; 4th, the gap time At the end of the timing, the pull cycle ends and the system then proceeds to the next pull cycle.

The existing vertebral body broaching machine has two kinds of manipulation modes, the first one needs to be assisted by a doctor or a nurse; the second type is operated by the patient independently, and the vertebral body pulling bed disclosed in Chinese Patent Publication No. 204219120U, 204428236U belongs to the second type. Control method. In the first mode of operation, after the patient is lying on the pulling bed, the doctor first fixes the waist strap and the head strap for the patient, and then operates the control panel to start the device operation. Since the pulling bed is controlled by a doctor, in the pulling test step, the doctor controls the motor to advance by manually testing the button. As the pulling force is gradually increased, the patient must promptly feed back information to the doctor when the pulling force reaches a suitable value so that the doctor can control the motor. Stop moving forward. In actual use, there is often a time difference from the patient sending a message to the doctor controlling the motor to stop, and it is easy to cause a strain accident due to excessive pulling force, which is a serious safety hazard existing in the existing product. Therefore, in order to ensure the safety of the test procedure, an emergency stop button controlled by the patient is separately set in the existing device. In an emergency situation, the patient can use the emergency stop button to control the motor to stop advancing to avoid injury due to excessive pulling force. In the second control mode, both the fixation of the traction belt and the operation of the control panel are operated by the patient.

Taking the prior art as an example, there are three ways to start the automatic operation of the device. In the first way, the controller can complete the tensile test step and the parameter setting step in sequence, and pull and pull in the parameter setting step. Set 4 parameters such as time, gap time and cycle number, then save the running parameters and start the device to enter the automatic running program. In the second way, the controller can enter the running parameters from the setting step without going through the testing steps. Set and save, then start the device to run automatically; the third way, the controller can also directly launch the device by directly calling up the control panel and selecting the appropriate operating parameters stored in the system without testing and setting two steps. Enter the automatic running program.

The problem is that in the actual use process, since the pulling force parameter is adjusted and adjusted by the controller through the button in the setting step, it is inevitable that an error occurs in the data adjustment. On the other hand, even in the same patient, if the position of the waist strap is fixed or the degree of tightness is different, the amount of traction that the patient can withstand when pulling is different. Therefore, the pull force parameter is tested by the controller in the test step and is adjusted and adjusted in the setting step, then saved and started automatically, or directly tested and set without two steps of testing and setting. The operating parameters in the system start the device to run automatically. These methods have certain safety hazards and may cause the patient to be strained.

BRIEF DESCRIPTION OF THE DRAWINGS:

FIG. 1 is a schematic diagram of a button arrangement of a control panel of the present invention.

Specific embodiment 1

In the present embodiment, referring to the arrangement diagram of the control panel buttons of FIG. 1, the method for controlling an automatic vertebral body pulling bed according to the present invention comprises the following steps:

First, the tensile test step: in the initial state, the system enters the waist test mode through the waist button. In the waist test mode, the motor is controlled to advance or retreat by the push button or the back button. At this time, the pull force value of the display is for the human body to pull. The measured value of the force, when the human body feels that the pulling force is appropriate, the long pull button is used to automatically deposit the current pulling force as the reference value of the pulling force setting into the system, and at the same time, the system enters the waist setting mode, In the waist setting mode, one of the three parameters, such as the number of cycles, the pulling time and the gap time, will be flashing.

In the initial state, the system enters the neck test mode by the neck button. In the neck test mode, the motor is controlled to advance or retreat by the push button or the back button. At this time, the pull force value of the display is the measured value of the human body to withstand the pulling force. When the tension is felt to be appropriate, the current pull force is automatically stored in the system as a reference value for the pull force setting by pressing the long button, and the system enters the neck setting mode. In the neck setting mode, the display is displayed. One of the three parameters, such as the number of cycles on the screen, the pull time, and the gap time, will be in a blinking state.

Second, the parameter setting step, in the waist setting mode, only three parameters such as the pulling time, the gap time, and the number of cycles can be adjusted. By setting the button, the parameter to be adjusted can be selected, and each time the setting is performed, When the button is pressed, the next parameter will flash. When a parameter on the display is flashing, the parameter can be adjusted by the +1 or -1 adjustment button. For example, when the number of cycles in the waist setting mode is flashing, you can adjust the parameter by +1 or -1 adjustment button, and then press the setting button again. The pull time parameter will flash and can be performed. Add or subtract adjustment, then press the set button again, the gap time parameter will flash and can be adjusted, then press the set button again, the loop count parameter will return to the flashing state again, after the parameter setting is completed. The operating parameters are saved to the system through the long ammonium setting button. The system enters the waist automatic mode. The system only saves the current set of operating parameters, and the original parameters are automatically overwritten. At this time, the parameters on the display are no longer flashing.

In the neck setting mode, only three parameters such as the pulling time, the gap time, and the number of cycles can be adjusted. The parameter to be adjusted can be selected by the setting button. Each time the setting button is pressed, the next parameter will flash. When a parameter on the display is flashing, the parameter can be adjusted by adding or subtracting by +1 or -1 adjustment key. For example, when the number of cycles in the neck setting mode is flashing, the parameter can be adjusted by the +1 or -1 adjustment button, and then the setting button is pressed again. The pull time parameter will flash and can be performed. Add or subtract adjustment, then press the set button again, the gap time parameter will flash and can be adjusted. If you want to return to the cycle number setting, you can press the setting button again, and the cycle number parameter will be returned again. To the flashing state, after the parameter setting is completed, save the running parameters to the system by long pressing the setting button. The system enters the neck automatic mode. The system only saves the current set of operating parameters, and the original parameters are automatically overwritten. The parameters are no longer flashing.

Third, the automatic pulling step: in the waist automatic mode, by running the button system to enter the waist automatic running program, the system will automatically complete The first pull cycle, the second pull cycle until the last pull cycle is completed, and the system automatically resets to the initial state at the end of the last pull cycle.

In the neck automatic mode, by running the button system to enter the neck automatic running program, the system automatically completes the first pulling cycle, the second pulling cycle until the last pulling cycle is completed, and the system automatically resets at the end of the last pulling cycle. To the initial state,

In this example, in the third step, the pulling force automatically set by the system in each pulling cycle of an automatic running program is equal to the reference value. For example, in the first step, if the appropriate pulling force of the human body in the waist test is 20KG, the 20KG is automatically stored in the system as a reference value for the pulling force setting by pressing the waist button; In the step, the pulling force automatically set by the system in each pulling cycle of an automatic running program is equal to 20KG.

In the first, second or third step, in the event of an emergency, the system can be reset to the initial state by a stop button, and saved to the system by the test step each time the system is automatically reset to the initial state. The pull force setting reference value will be automatically deleted, the system displays the measured value of the pulling force and only saves the last set of operating parameters including the pulling time, the gap time, and the number of cycles.

Based on the technical features of the first embodiment, the present invention also proposes the following preferred embodiments:

In another embodiment of the present invention, in the third step, the system automatically sets the first pulling force equal to the reference value minus 2KG and the second pulling force equal to each other in each pulling cycle of an automatic running program. The reference value is reduced by 1KG, and the pulling force of the third and subsequent times is equal to the reference value. For example, in the first step, if the appropriate pulling force of the human body in the waist test is 20KG, the 20KG is automatically stored in the system as a reference value for the pulling force setting by pressing the waist button; In the step, in the respective pulling cycle of an automatic running program, the system automatically sets the first pulling force equal to the reference value 20KG minus 2KG, that is, 18KG, and the second pulling force is equal to the reference value 20KG minus 1KG, that is, 19KG. The pulling force of the third and subsequent times is equal to the reference value of 20KG. In this example, the first three pulling forces are gradually increased in each cycle of the automatic pulling process, while the pulling forces from the third and subsequent are kept the same.

In another embodiment of the present invention, the system sets the ultimate tensile force safety value of the waist at 25KG-30KG, and sets the ultimate tensile force safety value of the neck to 15KG-20KG. Therefore, in this example, referring to FIG. 1, in the first step, in the waist test mode, the motor is advanced by the push button, and when the sensor detects that the pulling force of the human lumbar vertebra reaches the system-set waist safety limit value, the motor In the neck test mode, the motor is advanced by the push button. When the sensor detects that the tensile force of the human cervical vertebra reaches the neck safety limit set by the system, the motor will stop moving forward. Since the advancement or retreat of the motor in the test mode is manually controlled by the controller, setting the safety limit value can effectively prevent human error and avoid overloading the tension. At the same time, since the pull force setting reference value in the running parameter in an automatic running program is saved to the system by the button in the test step and cannot be adjusted in the subsequent setting step, the system is in the automatic running process. The actual pulling force of the waist is naturally controlled below the set waist safety limit, and the actual pulling force of the neck is controlled below the set neck safety limit. More effectively ensure the safe operation of the equipment. In order to ensure safety, the system's ultimate tensile safety value is solidified in the system, and the controller cannot adjust the safety value during use.

In another embodiment of the present invention, in the first step, the waist test mode and the neck test mode can be switched by buttons. In this example, referring to Figure 1, when in the waist test mode, the system can be switched to the neck test mode by the neck button. Similarly, when in the neck test mode, the system can be switched to the waist test mode by the waist button.

In another embodiment of the present invention, in the second step, in the waist setting mode, when the operating parameters are successfully saved to the system, the motor first automatically retreats for 1-2 seconds and then enters the waist automatic mode; In the mode, when the operating parameters are successfully saved to the system, the motor first automatically retreats for 1-2 seconds and then enters the neck automatic mode.

In another embodiment of the present invention, in the third step, in each pulling cycle of an automatic running program, the system automatically rolls back for 1-2 seconds at the end of the pulling time, and then the system enters the gap time again. Timing, after the end of the timer, enter the next pull cycle, the system automatically resets to the initial state at the end of the last pull cycle.

In another embodiment of the present invention, in the third step, when the system enters the automatic running program, the system automatically resets to the initial state when the sensor data line or the controller data line in the system falls off.

The control method of the automatic vertebral body pulling bed proposed by the present invention has the following technical features: the first and the pulling force are automatically saved in the system by the button in the test step of the first step and are in the first The pull force parameter in the two-step setting step cannot be adjusted. Second, each time the system is reset to the initial state, the pull force setting reference value originally saved to the system will be automatically deleted, and the system will display the measured value of the pulling force and save only the last set of pulling time. , gap time, cycle number of operating parameters. This ensures that the tension test must be passed before each time the automatic running program is entered, and the tension parameter can no longer be adjusted in the setting step. The pulling force set in the system is only set for the subsequent one. The running program is effective, which can eliminate the hidden dangers of the existing technology and effectively ensure safety.
