Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments.

Example one

Please refer to fig. 1, this embodiment discloses a circuit module for pelvic floor muscle repairing apparatus. The circuit module comprises an electrical stimulation module, a pelvic floor muscle electromyographic signal detection module, a positive electrode, a negative electrode, a reference electrode and a change-over switch. In fig. 1, one of the electrode sheet 1 and the electrode sheet 2 is a positive electrode, and the other is a negative electrode. The reference electrode is spatially located between electrode sheet 1 and electrode sheet 2. The relay is used as a change-over switch to switch the connection between the positive electrode and the negative electrode and the electrical stimulation module and the connection between the positive electrode and the negative electrode and the pelvic floor myoelectric signal detection module. When the change-over switch is at a first change-over position, the positive electrode and the negative electrode are electrically connected with the electrical stimulation module; when the change-over switch is in a second change position, the positive electrode and the negative electrode are electrically connected with the pelvic floor myoelectric signal detection module; the reference electrode is electrically connected with the pelvic floor myoelectric signal detection module all the time.

Preferably, in the circuit module, in order to reduce power consumption, a normally closed point of the relay needs to be connected to the electrical stimulation module (stimulation time is longer than collection time), when the pelvic floor electromyography signals need to be detected, the coil of the relay is electrified, the electrode plate is switched to the electromyography signal detection module, and the electrified coil has adverse effects on the electromyography signals. In order to solve the influence, a self-holding relay is adopted, the electric shock switching of the relay only needs to supply positive and negative pulses to the coil, continuous power supply is not needed, the problem of power consumption is solved, and meanwhile the influence of the electrified coil on the electromyographic signals is avoided.

The reference electrode is connected to the reference potential of the main board, is connected when electromyographic signals are collected, and needs to be cut off when stimulation is carried out, so that the stimulation current is prevented from flowing between the two electrode plates instead of flowing through the reference electrode bypass when the electrical stimulation physiotherapy is carried out. The reference potential to which the reference electrode is connected serves as a reference for comparing the acquired signals, so that the acquired signals are more accurate and stable.

In this embodiment, the adopted electrostimulation module and the pelvic floor myoelectric signal detection module can be replaced by the existing module in the prior art, and the reduction of the electrode plates required by this embodiment to realize the miniaturization of the whole structure will not cause influence. For example, the electrical stimulation module can output random combined square waves with variable pulse width (50 us-400 us), variable frequency (5-200 Hz) and variable intensity (0-70 mA) to the positive electrode and the negative electrode to generate electrical stimulation. The pelvic floor myoelectric signal detection module adopts a myoelectric signal detection module commonly used in the prior art.

Wherein the front end housing 11 is in contact with the human vagina in use. The positive electrode and the negative electrode are respectively attached to the outer walls of the two sides of the front end shell 11. The electrode sheet 2 in fig. 2 is a positive electrode or a negative electrode, and the other electrode sheet is symmetrically positioned at the back of the electrode sheet 2. And the reference electrode 3 is located at a position between the positive and negative electrode sheets below the front end case 11. The electrical stimulation module, the pelvic floor muscle electromyographic signal detection module and the relay are located inside the main shell body and inside the front end shell body 11 in the embodiment. The front end shell 11 is also internally provided with a heater to play a heating function, so that the front end shell 11 has proper temperature when contacting with a human body to improve the comfort of the human body. And the rear end shell 12 is provided with a key 4 and an indicator light, so that the operation is convenient.

As can be seen from the second embodiment, the electrodes, the electrical stimulation module, and the pelvic floor myoelectric signal detection module are integrated in the front-end housing 11. Therefore, the whole structure does not need external wires and more than two groups of positive and negative electrode plates. The whole product structure is integrated and is more compact and portable. Meanwhile, the positive and negative electrodes are shared by the pelvic floor myoelectric signal detection module and the electrical stimulation module, so that only three parts contacting the human body are provided, and the parts are divided into the positive and negative electrodes and the reference electrode. The area of the positive electrode and the negative electrode can be larger, so that the contact area of pelvic floor muscles is larger, the treatment effect is better, and the treatment is easier to realize on equipment processing.
