Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a pulse adaptive regulation method and therapeutic equipment. Background Art

[0002] The pneumatic ballistic extracorporeal shock wave therapy device is a physical therapy device used to treat skeletal muscle diseases. Its working principle is to convert the internal energy of compressed air into mechanical energy to act on human muscle tissue. The air from the air compressor pushes the bullet head of the treatment handle through the opening and closing of the solenoid valve, and accelerates the movement in the pipe of the treatment handle to hit the treatment head. The treatment head acts on the trigger point of the human body, improves the functional disorder of the area affected by the trigger point, decomposes the accumulated metabolic products, stimulates the affected area muscle group, blocks the centripetal pain transmission, and thus achieves the therapeutic effect of relieving pain.

[0003] When the existing pneumatic ballistic extracorporeal shock wave therapy device is working, the pulse width corresponding to each frequency and shock pressure is fixed. This will cause the treatment handle to be unable to collide back and forth normally in a low-frequency or high-frequency state due to differences in the assembly structure of different treatment handles or normal aging reasons, so as to output the ideal penetration depth and energy density to the patient's diseased part. The error may even exceed 50% of the target shock pressure, seriously affecting the treatment accuracy and treatment effect of the treatment handle, and failing to achieve the purpose of precise treatment. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a pulse width adaptive regulation method and a therapeutic device, which achieve the purpose of pulse width adaptive regulation and solve the problems in the background technology.

[0005] A pulse width adaptive adjustment method of the present invention is applied to a shock wave therapy device, wherein the shock wave therapy device comprises a treatment handle, wherein the treatment handle comprises a bullet body and a treatment head, wherein the treatment head is provided with a pressure detection device, wherein the method comprises the following steps:

[0006] S01, setting a target frequency at which the bullet body impacts the treatment head and a target impact pressure generated during the impact;

[0007] S02, detecting, by the pressure detection device, the actual impact pressure generated by the bullet body hitting the treatment head when working at the target frequency;

[0008] S03, calculating the difference between the actual impact pressure and the target impact pressure, and determining whether the difference is within a first threshold range;

[0009] S04, if the difference is not within the first threshold range, adjusting the pulse width corresponding to the target frequency by a unit value, and storing the adjusted pulse width data in a storage unit, and returning to step S02;

[0010] S05. Repeat steps S02 to S04 until the difference is within the first threshold range.

[0011] As a preferred solution, in step S04, if the actual impact pressure is greater than the target impact pressure, the pulse width is reduced by one unit value;

[0012] If the actual impact pressure is less than the target impact pressure, the pulse width is increased by one of the unit values.

[0013] As a preferred solution, in step S05, if the difference is still not within the first threshold range after all pulse width values ​​have been adjusted, the first threshold range is adjusted to the second threshold range, and a pulse width that satisfies the difference within the second threshold range is searched in the storage unit, wherein the range of the second threshold range is larger than the range of the first threshold range.

[0014] As a preferred solution, if all pulse width values ​​found in the storage unit correspond to actual impact pressure data and do not meet the condition that the difference is within the second threshold range, it is determined that the treatment handle has failed and the failure information is reported.

[0015] The present invention also provides a treatment device, including a main unit and a treatment handle, wherein the treatment handle includes a bullet body and a treatment head, and the treatment head is provided with a pressure detection device; when the treatment device is working, the pulse width adaptive adjustment method of any of the above schemes is executed.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: when the bullet body hits the treatment head at the target frequency, the actual impact pressure generated when the bullet body hits the treatment head is detected in real time by the pressure detection device arranged on the treatment head, and the difference between the actual impact pressure and the target impact pressure is calculated, and it is judged whether the difference is in the first threshold interval, so as to judge whether the actual impact pressure meets the expected target. If the difference is not in the first threshold interval, the difference between the actual impact pressure and the target impact pressure is returned to the first threshold interval by adjusting the pulse width corresponding to the target frequency, so as to realize the dynamic adjustment of the pulse width according to the impact pressure fed back in real time, so that the actual impact pressure is maintained within the expected target impact pressure range, thereby obtaining an ideal penetration depth and energy density. The problem that the penetration depth and energy density of the treatment handle do not meet the expected requirements when working is solved, and the purpose of precision treatment is achieved.

They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0021] Combination Figure 1 As shown, a pulse width adaptive adjustment method of the present invention is applied to a shock wave therapy device, wherein the shock wave therapy device comprises a main unit and a treatment handle, wherein the treatment handle comprises a bullet body and a treatment head, wherein the treatment head is provided with a pressure detection device, wherein the method comprises the following steps:

[0022] S01, setting a target frequency at which the bullet body impacts the treatment head and a target impact pressure generated during the impact;

[0023] S02, detecting, by the pressure detection device, the actual impact pressure generated by the bullet body hitting the treatment head when working at the target frequency;

[0024] S03, calculating the difference between the actual impact pressure and the target impact pressure, and determining whether the difference is within a first threshold range;

[0025] S04, if the difference is not within the first threshold range, adjusting the pulse width corresponding to the target frequency by a unit value, and storing the adjusted pulse width data in a storage unit, and returning to step S02;

[0026] S05. Repeat steps S02 to S04 until the difference is within the first threshold range.

[0027] For example, before the shock wave therapy device starts working, the target frequency of the bullet body hitting the treatment head is set to 1Hz (Hertz), and the target impact pressure generated during the impact is set to 1bar (bar). Then start working, so that the bullet body reciprocates and hits the treatment head at the target frequency of 1Hz. At this time, the actual impact pressure generated by the bullet body hitting the treatment head for the first time is detected by the pressure detection device set on the treatment head. The detection device transmits the pressure data obtained by the detection back to the host of the shock wave therapy device, and the difference between the actual impact pressure and the target impact pressure is calculated by the host of the shock wave therapy device, and the difference is compared with the first threshold interval in the database to determine whether the difference is in the first threshold interval. If the difference is not in the first threshold interval, the pulse width corresponding to the target frequency is adjusted by a unit value, and the adjusted pulse width data is stored in the storage unit, thereby completing the first pulse width adjustment. The adjustment of the pulse width can indirectly change the actual impact pressure generated by the bullet body hitting the treatment head.

[0028] When the pulse width is adjusted for the next time, the projectile body is reciprocated to hit the treatment head at the target frequency, and then the actual impact pressure generated by the projectile body hitting the treatment head is detected by the pressure detection device arranged on the treatment head. The detection device transmits the pressure data obtained by the detection back to the host of the shock wave therapy device, and the host of the shock wave therapy device calculates the difference between the actual impact pressure and the target impact pressure, and compares the difference with the first threshold interval in the database to determine whether the difference is within the first threshold interval. If the difference is not within the first threshold interval, the pulse width corresponding to the target frequency is adjusted by a unit value, and the adjusted pulse width data is stored in the storage unit, thereby completing the second pulse width adjustment.

[0029] The pulse width is adjusted by continuously repeating the above steps until the difference between the actual impact pressure and the target impact pressure is within the first threshold range.

[0030] Preferably, in step S04, if the actual impact pressure is greater than the target impact pressure, the pulse width is reduced by one unit value. For example, taking the target frequency as 1 Hz (hertz) and the target impact pressure generated during the impact as 1 bar (bar) as an example, assuming that the first threshold interval is (-0.05, 0.05). If the measured actual impact pressure is 1.07 bar (bar), at this time, the difference with the target impact pressure of 1 bar (bar) is 0.07, the difference is not within the first threshold interval, and the actual impact pressure is greater than the target impact pressure, then the pulse width is reduced by 0.1 ms (milliseconds).

[0031] Furthermore, if the actual impact pressure is less than the target impact pressure, the pulse width is increased by one unit value. For example, taking the target frequency of 1 Hz (hertz) and the target impact pressure of 1 bar (bar) as an example, assuming that the first threshold interval is (-0.05, 0.05). If the measured actual impact pressure is 0.93 bar (bar), at this time, the difference with the target impact pressure of 1 bar (bar) is -0.07, the difference is not within the first threshold interval, and the actual impact pressure is less than the target impact pressure, then the pulse width is increased by 0.1 ms (milliseconds).

[0032] In step S05, if all pulse width values ​​are adjusted, but the difference between the actual impact pressure and the target impact pressure corresponding to all pulse width values ​​is still not within the first threshold interval, the first threshold interval is adjusted to the second threshold interval, and the pulse width corresponding to the actual impact pressure whose difference is within the second threshold interval is searched in the storage unit, wherein the second threshold interval range is larger than the first threshold interval range. For example, still taking the target frequency as 1 Hz (Hertz) and the target impact pressure generated during the impact as 1 bar (bar) as an example, assuming that the first threshold interval is (-0.05, 0.05) and the second threshold interval is (-0.1, 0.1). After all pulse width values ​​are adjusted, the pulse width values ​​recorded when multiple adjustments are made will be stored in the storage unit. Each pulse width value corresponds to an actual impact pressure value. If the actual impact pressure corresponding to a certain pulse width record value is found in the storage unit to be 0.93 bar, the difference between the actual impact pressure and the target impact pressure is -0.07. This difference is not within the first threshold range, but within the second threshold range. The actual impact pressure can also be considered to be in line with the expected impact pressure.

[0033] If all pulse width values ​​found in the storage unit correspond to actual impact pressure data, and none of them meet the condition that the difference is in the second threshold interval, it is determined that the treatment handle has failed, and the fault information is reported. For example, still taking the target frequency as 1 Hz (Hertz) and the target impact pressure generated during the impact as 1 bar (bar), it is assumed that the first threshold interval is (-0.05, 0.05) and the second threshold interval is (-0.1, 0.1). After all pulse width values ​​are adjusted, multiple pulse width values ​​recorded during the adjustment will be stored in the storage unit, and each pulse width value corresponds to an actual impact pressure value. If the difference between the actual impact pressure and the target impact pressure corresponding to all pulse width record values ​​found in the storage unit is neither in the first threshold interval nor in the second threshold interval, it is determined that the treatment handle has failed, and the fault information is reported.

[0034] The present invention also provides a treatment device, including a main unit and a treatment handle, wherein the treatment handle includes a bullet body and a treatment head, and the treatment head is provided with a pressure detection device; when the treatment device is working, the pulse width adaptive adjustment method of any of the above schemes is executed.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] When the bullet body hits the treatment head at the target frequency, the actual impact pressure generated when the bullet body hits the treatment head is detected in real time by the pressure detection device set on the treatment head. The difference between the actual impact pressure and the target impact pressure is calculated, and it is determined whether the difference is in the first threshold interval to determine whether the actual impact pressure meets the expected target. If the difference is not in the first threshold interval, the difference between the actual impact pressure and the target impact pressure is returned to the first threshold interval by adjusting the pulse width corresponding to the target frequency, so that the pulse width is dynamically adjusted according to the real-time feedback impact pressure, so that the actual impact pressure is maintained within the expected target impact pressure range, thereby obtaining an ideal penetration depth and energy density. The problem that the penetration depth and energy density of the treatment handle do not meet the expected requirements when working is solved, and the purpose of precision treatment is achieved.
