Background

The pelvic floor muscles of women have the function of maintaining the normal anatomical positions of pelvic organs, participate in urination and defecation, maintain the normal muscle tension and play an important role in the physical and mental health of women. The female pregnancy and childbirth may cause damage to pelvic floor muscles, generate great traction and shear force to the muscles, delay nerve conduction, reduce the contraction strength of the muscles, cause decrease in muscle tension, and cause relaxation of pelvic floor tissues. As women age, pelvic floor dysfunctional diseases can be caused, and the psychology and the life of the women are seriously influenced.

The pelvic floor muscle electrical stimulation is a method for electrically stimulating pelvic floor tissues by using an internal electrode and an external electrode of a vagina or an anus so as to enhance the capability of the pelvic floor muscles. Pelvic floor muscle electrical stimulation is mainly classified into implantable, invasive and non-invasive, wherein an implantable electrode implants an electrode patch under the skin, an invasive electrode usually places a rod-shaped electrode in the pudendum or anus, and a non-invasive electrode places the electrode on the skin surface or inside underwear.

The main pelvic floor electrical stimulation device on the market mostly adopts invasive double-electrode acupuncture stimulation. Invasive electrodes cause local discomfort to the patient and the current density of the tissue surrounding the invasive electrode is high, causing small amplitude damage to the tissue.

The following describes the medical electrical stimulation treatment device according to the present embodiment with reference to the drawings.

Referring to fig. 1, fig. 1 is a schematic view of a medical electrical stimulation treatment device according to an embodiment of the present invention, and the embodiment provides a medical electrical stimulation treatment device including: an electrical stimulation circuit 10 for providing a stimulation current; three electrodes 20, said electrodes 20 being intended to be applied against respective predetermined sites (in particular against the skin of the patient, each electrode 20 being applied against a corresponding skin site, depending on the site actually to be treated); any two electrodes 20 are used for forming a loop with the electrical stimulation circuit 10, and it can be understood that three electrodes 20 can form three loops together with the stimulation circuit, the loops are used for circulating the stimulation current, and the electrodes 20 are attached to the patient, so that the electrical stimulation treatment on the patient is realized; the medical electrical stimulation treatment device is used for driving one of the three circuits to operate, namely the three circuits cannot operate simultaneously, a doctor can select any one circuit to operate, and when the circuit operates, the other two circuits are in a stop state. Compared with the conventional non-invasive electrostimulation device in the prior art, which is composed of two external electrodes 20, the medical electrostimulation treatment device has weaker and unstable current intensity, and the application can understand that the third electrode 20 is introduced to form a different stimulation loop, so that stronger and complementary current stimulation can be formed, a stable treatment process for a patient is facilitated, and the treatment effect is improved. In addition, compared with the prior invasive electrical stimulation device which needs to place the electrode 20 in the body of the patient (for example, inserting a long acupuncture needle into the muscle tissue of the patient), the electrode 20 of the present application is attached to a predetermined position (i.e., the skin of the patient), and does not need to be placed in the body of the patient, so that the uncomfortable experience of the patient can be avoided, and the operation process is simpler.

In this embodiment, the operation sequence of the three circuits is not limited. The third loop is sequentially marked as a first loop, a second loop and a third loop, wherein the second loop is operated after the first loop is operated for a period of time, and the third loop is operated after the second loop is operated for a period of time, namely the three loops are operated in a round-robin manner; one of the circuits may be operated all the time, such as the first circuit; it may be that the second circuit is operated after the first circuit is operated for a certain period of time. It should be noted that, in general, after each circuit is operated for a certain period of time (preset time), the next circuit is operated at a preset rest time interval, or the originally selected circuit is continuously operated. It can be understood that after the stimulation current flows in one loop for a preset time, the stimulation current is selected to continue flowing in the original loop or another loop for a rest time. The preset duration and the rest duration can be configured according to practical choices by those skilled in the art, and are described in detail herein.

Optionally, at least a part of the surface of the medical electrical stimulation treatment device is configured as a treatment cushion 30, wherein the treatment cushion 30 is used for a predetermined object (patient) to sit down; three of the electrodes 20 are disposed on the therapeutic cushion 30.

Further, the electrodes 20 are in a shape of a sheet, three electrodes 20 are a first electrode 21, a second electrode 22 and a third electrode 23, the first electrode 21 and the second electrode 22 are arranged in parallel and in a coplanar manner, the third electrode 23 is located on a central perpendicular line of a connecting line of the first electrode 21 and the second electrode 22, and the third electrode 23 is arranged at an angle to the first electrode 21, i.e. the third electrode 23 is arranged at an angle to the plane shared by the first electrode 21 and the second electrode 22, and, as such, the three electrodes 20 can be made to be approximately L-shaped, so that after the patient lies on the treatment cushion 30, the skin of the patient's buttocks is brought into contact with the first electrode 21 and the second electrode 22, the skin of the patient's caudal vertebra is brought into contact with the third electrode 23, then through the selected loop and the stimulation current, the electrical stimulation treatment is carried out on the hip muscle tissue and the tail vertebra muscle tissue of the patient. It should be noted that the angle of the "L" here can be adjusted, for example, can be 90 °, 120 °, etc., which is convenient for adapting to the body shapes of different patients, so that the patients have good experience, and the flexibility of the therapeutic cushion 30 is also reflected.

As shown in fig. 4 to 6, fig. 4 to 6 are schematic diagrams of a stimulation current according to an embodiment of the present invention, the stimulation current of the embodiment is a periodic stimulation current, specifically, the medical electrical stimulation treatment apparatus includes a main control circuit 40, the main control circuit 40 is connected to the electrical stimulation circuit 10, and the main control circuit 40 is configured to send a periodic pulse signal to the electrical stimulation circuit 10, so that the electrical stimulation circuit 10 converts the periodic pulse signal into the periodic stimulation current. The present embodiment does not limit the period of the stimulation current, such as 10s, and also does not limit the pulse width of the stimulation current, such as 3 μm.

With continued reference to fig. 4-6, the particular treatment process of the present invention is illustrated in the particular manner exemplified in the figures.

The duration, pulse interval and pulse width of the working stage and the rest stage can be adjusted according to actual conditions, and different modes are suitable for patients with different symptoms and different stages. Specifically, the physician selects a specific operation mode of the three circuits, and can select the three circuits to run in a round-robin manner, or run one circuit all the time, or run another circuit all the time after the operation of one circuit is finished. Referring to fig. 2, the stimulation current has a period of 10s, is discharged in the same loop for 10s, and is discharged for 10s after an interval of 5s, in such a way that the stimulation current circulates in this loop for 5 minutes, thus being considered as a treatment period (i.e., the operating time period identified in fig. 6). Then the patient takes a rest for 2 minutes and carries out the next treatment cycle, and the circuit selection of the next treatment cycle can be the original circuit or another circuit.

It should be noted that.

Further, the main control circuit 40 is configured to send a current check instruction to the electrical stimulation circuit 10 after obtaining a control instruction, and drive the electrical stimulation circuit 10 to detect the running state of the electrical stimulation circuit 10. Before the patient is subjected to electrical stimulation treatment, a doctor needs to check whether the medical electrical stimulation treatment device operates normally, so that the side effect on the patient caused by the abnormality of the device in the treatment process of the patient is avoided. Here, the electrostimulation circuit 10 detects its own operating state, including but not limited to detecting whether there is an overcurrent or short circuit phenomenon in the electrostimulation circuit 10.

Therefore, the doctor can conveniently check the running state and the current intensity of the stimulating current in real time, and the doctor can conveniently adjust the intensity and the duration of the stimulating current at any time according to the actual condition.

Optionally, the main control circuit 40 is externally connected to a control panel 60 or a wireless intelligent terminal 70 device. Specifically, the control instruction is sent to the main control circuit 40 through the control panel 60 or the wireless smart terminal 70. In addition, the embodiment is further provided with a wireless module to realize information interaction between the wireless intelligent terminal 70 and the medical electrical stimulation treatment device.
