In the prior art, electrical stimulation training for pelvic floor muscles is usually an electrical stimulation cycle method. For example, the current intensity setting during electrical stimulation needs to be set based on human subjective experience, and cannot be based on quantitative parameters, resulting in the electrical stimulation current intensity used not matching the actual value that should be required.

[0003] Therefore, a new technical solution is needed to solve the above problems. Summary of the invention

[0004] Purpose of the invention: The present invention provides a method of pelvic floor ultrasonic electromyographic pressure combined with electrical stimulation to solve the problem that the current intensity of electrical stimulation cannot be set according to quantitative parameters.

[0009] The cavity is expanded to a first state by inflating the elastic body to a first volume, and a first pressure value P1 to which the elastic body is subjected when the elastic body is at the first volume is recorded;

[0010] After the cavity is changed from the first state to the second state, the second pressure value P2 to which the elastic body is subjected when in the first volume is recorded and the first pressure difference △P1=P2-P1 is calculated;

[0011] Inflate the elastic body to a second volume, record a third pressure value P3 to which the elastic body is subjected when the elastic body is at the second volume, and detect the width of the cavity expanded by the elastic body by an ultrasonic probe until the width reaches a preset width L1, and then stop inflating the elastic body;

[0013] Furthermore, when △P2=0.5△P1-2△P1, the cavity width changes from width L' to width L0, and the current value is adjusted to M0≈(L ’ *M ’ ) / L0.

[0014] Furthermore, when the electrical stimulation is generated by the current value M' or the current value M0, a pressure-following electrical stimulation scheme is adopted: when the conductive electrode generates electrical stimulation, the elastic body is inflated synchronously, and when the conductive electrode does not generate electrical stimulation, the elastic body is deflated synchronously;

[0015] Furthermore, when electrical stimulation is generated by the current value M' or the current value M0, a pressure-free electrical stimulation scheme is adopted: when the conductive electrode generates electrical stimulation, the elastic body maintains a fixed pressure.

[0016] Furthermore, when the electrical stimulation is generated by the current value M' or the current value M0, a partial pressure following electrical stimulation scheme is adopted: a free combination scheme of pressure following for part of the time and pressure not following for part of the time.

[0017] Furthermore, the ultrasonic frequency of the ultrasonic probe is 4 MHz-9 MHz.

Furthermore, when the cavity width changes from width L' to width L0, the corresponding current value is adjusted to M0≈(L ’ *M ’ ) / L0, the requirement of electrical stimulation can still be met, and the current value M0 still has an objective and quantifiable reference value as a parameter.

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 The present invention is a flow chart of the method of pelvic floor ultrasonic electromyographic pressure combined with electrical stimulation. DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please combine Figure 1 As shown, this embodiment provides a method for pelvic floor ultrasound electromyography combined with electrical stimulation, comprising:

[0032] A probe is provided, which has an elastic body and a conductive electrode located on the surface of the elastic body; the elastic body expands or contracts by inflating or deflating air; the elastic body is used to collect pressure values, and the conductive electrode is used to generate electrical stimulation. The elastic body is connected to a pressure sensor in a host, and the pressure value of the elastic body is obtained through the pressure sensor. In this embodiment, the probe can be a probe with an inflatable elastic body and an electrode in the prior art.

[0033] The cavity is expanded to a first state by inflating the elastic body to a first volume, and a first pressure value P1 exerted on the elastic body at the first volume is recorded, where P1=0-30 mmHg. In this embodiment, the cavity is a simulated cavity for testing, and the probe is expanded in the human vagina and records the pressure value generated by the pelvic floor muscles in a real use scenario.

[0034] After the cavity is changed from the first state to the second state, the second pressure value P2 exerted on the elastic body at the first volume is recorded and the first pressure difference △P1=P2-P1 is calculated. In this step, the "cavity is changed from the first state to the second state" can be contracted as needed in the simulated cavity. In the actual use scenario, the user performs the Valsava maneuver, inhales and exhales, and holds for about 6 seconds before recording the second pressure value generated by the pelvic floor muscles.

[0035] The elastic body is inflated to a second volume, a third pressure value P3 to which the elastic body is subjected at the second volume is recorded, and the width of the cavity expanded by the elastic body is detected by an ultrasonic probe until the preset width L1 is reached, and then the inflating of the elastic body is stopped. When the preset width L1 is reached, it is considered that the third pressure value P3 has met the requirement.

[0036] Generate electrical stimulation through conductive electrodes, record the fourth pressure value P4 to which the elastomer is subjected when the conductive electrodes generate electrical stimulation, and calculate the second pressure difference △P2==P4-P3; adjust the current value used for electrical stimulation until △P2=0.5△P1~2△P1, and record the current value M' used at this time and the width L' of the cavity detected by the ultrasonic probe at this time; the current value M' and width L' at this time are recorded as the current value data and width data of the cavity that meet the requirements of electrical stimulation. Thus, the user can use the current value M' and the cavity width L' obtained by inflating the elastomer as the initial setting value each time. With this solution, there is no need to set the current value M' subjectively by humans, but the current value M' of electrical stimulation is calculated in combination with the initial setting of the cavity width L' as a reference value, so that the current value M' of the electrical stimulation is set with an objective and quantifiable reference value as a parameter.

[0037] When △P2=0.5△P1~2△P1, if the width of the cavity changes from width L' to width L0, the initially set current value M' is no longer applicable, and the current value needs to be adjusted to M0≈(L ’ *M ’ ) / L0, it can still meet the requirements of electrical stimulation.

[0038] When electrical stimulation is generated by the current value M' or the current value M0, a pressure-following electrical stimulation scheme, a pressure-non-following electrical stimulation scheme, or a pressure-partially-following electrical stimulation scheme may be selected.

[0039] The pressure-following electrical stimulation scheme is: the elastic body is inflated synchronously when the conductive electrode generates electrical stimulation, and the elastic body is deflated synchronously when the conductive electrode does not generate electrical stimulation;

[0040] The pressure does not follow the electrical stimulation scheme: when the conductive electrode generates electrical stimulation, the elastic body maintains a fixed pressure.

[0041] The partial pressure-following electrical stimulation program is a free combination of pressure-following for part of the time and pressure-non-following for part of the time.

[0042] In addition, there are many specific implementation methods and approaches of the present invention, and the above is only a preferred implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
