Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to effectively treat patients, the treatment modes comprise first-line behavior treatment, second-line medicine treatment, three-line injection of botulinum toxin, sacral nerve regulation, tibial nerve stimulation treatment and the like. The tibial nerve stimulation treatment is to use a tibial nerve stimulation device, attach an electrode plate on the skin of a user, input current parameters required by treatment according to personal diagnosis experience by a doctor, generate corresponding stimulation current by the tibial nerve stimulation device, and transmit the stimulation current to the skin of a patient through the electrode plate to finally transmit the stimulation current to the tibial nerve for treating the patient.
However, the current common tibial nerve stimulation device has the following technical problems that in the process of transmitting the stimulation current to the tibial nerve through skin, waveform distortion, amplitude attenuation and the like of the stimulation current can occur, so that the current reaching the tibial nerve is different from the current displayed by the tibial nerve stimulation device, the displayed current value is different from the current value actually reaching the user tibial nerve, and the doctor treatment is misled.
In order to solve the above problems, a current parameter visualization method for percutaneous tibial nerve stimulation provided by the embodiments of the present application will be described and illustrated in detail by the following specific examples.
Referring to fig. 1, a flow chart of a method for visualizing electrical parameters for percutaneous tibial nerve stimulation is shown in accordance with an embodiment of the present invention.
In one embodiment, the method is applicable to a tibial nerve stimulation device provided with electrode pads that can be applied to the skin of a patient. The tibial nerve stimulation device can be connected with a user terminal or a control terminal, and the user terminal and the control terminal can be a controller or a mobile phone terminal. The mobile phone terminal can set an app, and the app controls operations such as parameter, start or adjustment of the tibial nerve stimulation device.
Wherein, as an example, the current parameter visualization method for percutaneous tibial nerve stimulation may include:
S11, acquiring impedance characteristic parameters related to the skin of a patient.
In one embodiment, the impedance characteristic parameter may be an impedance value of the user's skin.
In this embodiment, the impedance characteristic parameter includes a plurality of impedance characteristic values.
As an example, step S11 may include the following sub-steps:
s111, after a stimulation area of a patient is determined, arbitrarily selecting a plurality of points to be detected skin points from the stimulation area.
S112, randomly combining the plurality of detection skin points in pairs according to a preset interval to obtain a plurality of detection combinations.
S113, detecting skin resistance between two detected skin points contained in each detection combination, and obtaining a plurality of impedance characteristic values.
For example, the stimulation area of the patient to be subjected to the stimulation treatment is an arm, and a plurality of points can be arbitrarily selected in the arm area as the detected skin points. For example, 6 points, a, b, c, d, e and f points, respectively, were selected.
If the distance between two points is too small, two points can be defaulted to be the same point, and the impedance characteristic value is negligible. The 6 can be combined in pairs according to a preset interval to obtain a plurality of detection combinations. For example, the distances between the points a, b, c, d, e and f are larger than the preset distance, the 5 points a, b, c, d, e and f can be combined two by two to obtain 5 detection combinations, the distances between the point b and the two points e and f are larger than the preset distance, the 2 points b and e and f are combined two by two to obtain 2 detection combinations, and so on.
Finally, the skin resistance between the two detected skin points included in each detection combination is detected, so that a plurality of impedance characteristic values can be obtained.
S12, calculating an attenuation proportion value corresponding to the impedance characteristic parameter by using an artificial intelligence algorithm.
After the impedance characteristic parameters are determined, the attenuation proportion value corresponding to the attenuation of the current generated by the tibial nerve stimulation device in the human body can be calculated based on the impedance characteristic parameters.
In this embodiment, the impedance characteristic parameter includes a plurality of impedance characteristic values.
As an example, step S12 may include the following sub-steps:
s121, simulating and generating a human body simulation circuit according to the plurality of impedance characteristic values.
In one embodiment, an analog circuit for human body impedance may be preset, then a plurality of impedance characteristic values may be summed and averaged, and finally the average value is substituted into the analog circuit to obtain the human body analog circuit.
Referring to fig. 2, a schematic circuit diagram of a human body simulation circuit according to an embodiment of the present invention is shown.
Specifically, the analog circuit can be two common human body impedance analog circuits, namely a weighted sensing current circuit or a weighted getting-out current circuit, and the average impedance value of summation can be substituted into R2 or R3 of FIG. 2 to form the human body analog circuit.
S122, calculating corresponding analog current values of the human body analog circuit under a plurality of different stimulation voltages by using an artificial intelligence algorithm, wherein the plurality of different stimulation voltages are extracted from a treatment-bearable voltage interval section of a patient at will.
In one embodiment, a treatment voltage interval that the patient being treated can withstand may be obtained, and then a plurality of different stimulation voltages may be arbitrarily selected from the interval, e.g., interval 5-10 volts, within which 5 volts, 5.2 volts, 5.5 volts, 6 volts, 6.9 volts, 7.3 volts..9.2 volts, etc. may be selected.
Then each stimulating voltage is added into the human body simulation circuit, and the current value of the human body under the action of each stimulating voltage is acquired.
S123, according to a preset mapping relation table, obtaining a set current value corresponding to each stimulation voltage, and calculating a difference value between each set current value and each corresponding analog current value to obtain a plurality of current difference values.
In an embodiment, the preset mapping table may include a stimulus voltage and a set current value corresponding to the stimulus voltage, where the set current value is a set current value expected to reach the tibial nerve of the user.
Then, the difference between each set current value and each corresponding analog current value can be calculated to obtain a plurality of current difference values.
The current difference is the difference of current attenuation in the human body.
S124, calculating the ratio of each current difference value to the corresponding set current value to obtain a plurality of current ratios.
And S125, summing and averaging the current ratios to obtain an attenuation ratio value.
Dividing each current difference value by the corresponding set current value to obtain a corresponding current ratio value of each current difference value.
And finally, summing and averaging the current ratios to obtain the attenuation ratio value.
And S13, determining the stimulation current parameters reaching the tibial nerve of the user based on the attenuation proportion value, and visually displaying the stimulation current parameters.
After the attenuation proportion value of the human body is determined, the stimulation current parameter which actually reaches the user tibial nerve can be calculated based on the attenuation proportion, and the actual parameter is displayed so as to reduce errors.
Since the skin impedance of users of different ages may also be different, the impedance value obtained by calculation is also only a reference value, in order to further fit the personal reality of the user, in one of the embodiments the stimulation current parameter comprises several different stimulation current values.
As an example, step S13 may include the following sub-steps:
s131, adding the attenuation ratio value with a plurality of different preset ratio values respectively to obtain a plurality of different adjustment ratio values.
The preset proportion value may be an error value set by a user, for example, the attenuation proportion is 5%, the preset proportion value may be +0.5%, -0.5%, +1%, -1%, and after the attenuation proportion values are respectively added to different preset proportion values, 5.5%, 4.5%, 6%, and 4% of total 4 adjustment proportion values are obtained.
S132, calculating the stimulation current reaching the user tibial nerve according to each adjustment proportion value to obtain a plurality of different stimulation current values.
The stimulation current to the user's tibial nerve is then calculated based on the adjustment scale value.
Specifically, in combination with the above examples, 4 adjustment ratio values of 5.5%, 4.5%, 6%, and 4% are obtained, and assuming that the stimulus voltage is 10 v and the corresponding set current value is 1 a, the calculated stimulus current values are 0.945 a, 0.955 a, 0.94 a, and 0.96 a, respectively, based on the four adjustment ratio values.
To facilitate the doctor to view patient information corresponding to the different stimulation current values for reference by the doctor, in one embodiment, step S13 may further include the following substeps:
s133, based on preset quantity values, respectively searching patient medical record information about the recovered patient corresponding to each stimulation current value, wherein the patient medical record information comprises disease symptom information and treatment feedback information.
Assuming that the preset number value is 5, 5 patient medical record information corresponding to each stimulation current value can be searched, and each patient medical record information is medical record information about a recovered patient.
In one embodiment, the patient medical record information includes disease symptom information and treatment feedback information.
In the case of searching for a plurality of patient medical records, there may be a patient having the same symptoms as the current patient, and in order to facilitate the doctor to view the same information, in an embodiment, after step S133, the method may include:
S21, acquiring personal symptom information of a patient, and calculating information similarity of the personal symptom information and each disease symptom information to obtain a plurality of information similarities.
Specifically, the information similarity between two pieces of information may be calculated by a neural network.
S22, selecting the target similarity with the largest value from the information similarities.
And S23, dynamically rendering and displaying the stimulus current value corresponding to the target similarity on a terminal screen if the target similarity is larger than a preset similarity.
And S24, if the target similarity is smaller than the preset similarity, dynamically rendering and displaying the patient medical record information corresponding to the target similarity on a terminal screen.
When the target similarity is larger than the preset similarity, the stimulation current value corresponding to the target similarity can be sent to the control terminal, and the stimulation current value is dynamically rendered and displayed on the terminal screen by the control terminal, so that a doctor can check the similarity and let the previous patient recover.
When the target similarity is smaller than the preset similarity, patient medical record information corresponding to the target similarity can be sent to the control terminal, and the patient medical record information is dynamically rendered and displayed on a terminal screen by the control terminal, so that a doctor can first check the similar patient medical record information recovered by a previous patient for reference by the doctor.
In an embodiment, the dynamic rendering mode may be a pop-up window or a prompt or vibration mode for display, and a dynamic effect, such as flashing, may be added to the screen.
S134, adopting a plurality of stimulation current values and patient medical record information corresponding to each stimulation current value to manufacture a treatment information table.
And S135, sending the treatment information table to a preset control terminal, so that the control terminal renders and visually displays different stimulation current values in the treatment information table in a terminal screen for a doctor to refer to.
Because the calculated stimulation current values are multiple, the stimulation current values and a plurality of patient medical record information corresponding to each stimulation current value can be executed into an instruction information table, and finally the treatment information table is sent to a preset control terminal, so that the control terminal can render and visually display different stimulation current values in the treatment information table in a terminal screen for a doctor to refer to.
Specifically, the treatment information table has two columns, the left column is the stimulation current value, and the right column is the patient medical record information.
The control terminal can gradually display a list of the treatment information table about the stimulation current value from hiding to highlighting in a fade-in mode.
In the embodiment, the invention provides a current parameter visualization method for percutaneous tibial nerve stimulation, which has the beneficial effects that the impedance characteristics of the skin of a patient can be obtained, then the current attenuation proportion of current in a human body caused by the impedance characteristics is determined based on an artificial intelligence algorithm, finally the stimulation current actually reaching the tibial nerve of the user is calculated by utilizing the attenuation proportion, and the stimulation current is visualized and displayed on a control terminal so as to improve the accuracy of display and provide a doctor with treatment reference.
