As shown in fig. 1, the stimulator structure of the method for detecting wear of an implanted electrode according to the embodiment of the present application shown in fig. 1 is schematically shown.
With the rapid development of the medical field, implantable neurostimulators are widely used in the treatment of the nervous system. Implantable neurostimulators are surgically implanted at specific locations to treat a patient's disease or condition.
The physician will evaluate whether a neurostimulator needs to be implanted according to the patient's condition and implant it into the corresponding component. The patient needs to monitor periodically after implantation of the neurostimulator in order to adjust the parameters of the stimulator according to the condition. Electrodes in neurostimulators are an important component thereof for delivering electrical signals to specific tissues or nervous systems. Electrodes are interfaces connecting between the neurostimulator and the target tissue, and are typically made of a conductive material. To ensure proper operation of the neurostimulator, the status of the electrodes needs to be monitored periodically. When the electrode is abnormal, the electrode needs to be replaced in time. Currently, the detection of neurostimulator electrodes is largely dependent on periodic examination by a medical professional and the determination of whether or not the electrode is worn by the professional medical equipment. The whole manual detection process is complicated, and user experience is affected.
Therefore, how to change the existing manual detection of the stimulator electrode is complicated, and further, the problem that needs to be solved at present is satisfied for user experience. The method for detecting the abrasion of the implanted electrode, provided by the embodiment of the application, is applied to terminal equipment. The terminal device of the present application may be a platform for serving a medical institution, and fig. 2 is a first flow chart of a method for detecting wear of an implanted electrode according to an embodiment of the present application, and referring to fig. 2, the method includes the following steps S201-S204.
S201: and acquiring impedance data of the user, wherein the impedance data is human body impedance data of the user acquired by the stimulator.
In S201, after the neurostimulator is implanted in the patient, the body impedance data of the patient is collected when the various body parameters of the patient are in a relatively stable state according to the work and rest habits of the patient. The user refers to the patient in whom the stimulator is implanted.
Before the impedance data of the user are acquired, the mode of acquiring the impedance data of the user can be determined based on the time period of implanting the stimulator into the user, different implantation time periods correspond to different acquisition modes, and different acquisition modes are set so as to better adapt to the requirements and physical states of the user, and then the normal work of the stimulator is ensured. As shown in fig. 3, fig. 3 is a second flow chart of a method for detecting wear of an implanted electrode according to an embodiment of the present application, and the method includes steps S301 to S303.
S301: and acquiring an implantation time period of the stimulator, wherein the implantation time period is a time period from the implantation date of the stimulator to the current time.
In S301, the current time is obtained by obtaining the implantation date of the stimulator into the human body, and the current time refers to the specific time at which the implantation date is obtained. And calculating the time period of implanting the stimulator into the human body, namely the implantation time period according to the implantation time and the current time. The use time and the use condition of the stimulator can be known according to the implantation time period. The implantation time of the stimulator is different for different patients, so the implantation time period corresponding to each stimulator is different.
S302: judging whether the implantation time period is within a preset time period or not, wherein the preset time period comprises a preset first time period and a preset second time period; the preset second time period is greater than the preset first time period.
In S302, after the implantation time period of the stimulator is obtained, it is determined whether the implantation time period is in a preset time period, where the preset time period is a normal operation time period of the electrode in the stimulator, and the preset time period includes a preset first time period and a preset second time period, where the preset first time period is a time period in which the electrode in the stimulator works normally in a front period, and the preset second time period is a time period in which the electrode in the stimulator works normally in a rear period, and the time corresponding to the preset second time period is greater than the time corresponding to the preset first time period.
For example, the user a implants the stimulator in 2019, 3/12, at a certain part of the body, the current time is 2021, 3/14, the implantation time period is 2 years, the preset first time period may be set between 3 years, the preset second time period may be set between 3-6 years, the preset second time period is set to be greater than the preset first time period, and it is determined whether the implantation time period is within the preset time period.
S303: if the implantation time period is within a preset first time period, confirming that the first acquisition mode is used for acquiring the human body impedance of the user, wherein the first acquisition mode is used for acquiring the user when the stimulator works, and the preset first time period corresponds to the first acquisition mode.
In S303, when the implantation time period is within the preset time period, it is determined that the implantation time period is specifically within the preset first time period or the preset second time period. When the implantation time period is within a preset first time period, the first acquisition mode is used for acquiring the human body impedance of the user, wherein the first acquisition mode is used for acquiring the human body impedance of the user when the stimulator works, namely, the impedance detection module is used for acquiring the human body impedance of the user when the stimulator is used for treating the implanted part. The technology involved in how the impedance detection module specifically collects the impedance of the human body is merely a conventional technical means adopted by those skilled in the relevant art, and therefore, further description is omitted herein. And when the acquisition mode is determined to be the first acquisition mode according to the implantation time period of the user, acquiring the impedance data of the user by using the first acquisition mode. When the stimulator does not work, the human body impedance of the user cannot be collected independently, and when the stimulator is in an abnormal working state, the human body impedance of the user is prevented from being collected by the impedance detection module, so that the user experience is poor.
In the above example, when the implantation time period of the user a is within the preset first time period, it is confirmed that the first acquisition mode is used to acquire the human body impedance of the user a, that is, the stimulator uses the impedance detection module to acquire the human body impedance of the user a when treating the user a, and the impedance data is fed back to the energy controller through bluetooth, so that the energy controller sends the impedance data to the terminal device.
In addition, when the implantation time period is within a preset second time period, the human body impedance of the user is confirmed to be acquired by using a second acquisition mode, wherein the second acquisition mode is that the user is acquired at least once every day, and the preset second time period corresponds to the second acquisition mode. The second acquisition mode is to acquire the user at least once every day, so that enough impedance data acquisition can be ensured every day, and the human body impedance condition of the user can be known more accurately, so that the subsequent analysis of the data is facilitated. In order to ensure that the acquired impedance data are acquired when the body parameters are relatively stable, an acquisition time point can be selected, for example, the impedance data of the user can be acquired in the early morning, the acquisition time point can be set according to the work and rest habits of the user, and the method is not particularly limited.
For example, when the implantation time period of the user a is 4 years, when the implantation time period is within the preset second time period, it is confirmed that the second acquisition mode is used for acquiring the human body impedance of the user a, that is, the impedance data is acquired for the user a from day to day, and when the selected time point is 6 a.m., the user a is automatically acquired at 6 a.m. every day, the impedance data acquired by the impedance detection module is transmitted by using bluetooth. When the second collection mode is used for the user, the collection touch of the impedance detection module can be set to be noninductive collection by default, and the influence on user experience due to the fact that the collection touch is large is avoided.
Further, when the implantation time period is within the preset second time period, the impedance data is collected at least once a day for the user, i.e., at least once a day. When the stimulator is in a working state, after the human body impedance data of the user are acquired, the impedance detection module can be used for continuously acquiring the impedance data of the user when the stimulator works, and the impedance data are recorded, so that the acquired impedance data can be analyzed one by one.
S202: and judging whether the impedance data meets the preset condition.
In S202 described above, by determining whether the impedance data satisfies the preset condition, it can be quickly determined whether the electrode is in an abnormal state. The preset conditions comprise three sub-conditions, and the first sub-condition comprises impedance data; the second piece includes a first duration of use of the stimulator; the third sub-condition includes impedance data and a second duration of use of the stimulator. Judging whether the impedance data meet any one of the preset conditions, and determining the abnormal state of the electrode of the stimulator according to the preset conditions met by the impedance data.
S203: if the impedance data meets the preset condition, confirming that the electrode of the stimulator is in an abnormal state, wherein the abnormal state is electrode abrasion.
In S203, any one of three sub-conditions of the preset conditions may be used alone to confirm the abnormal state of the electrode of the stimulator. Therefore, three ways of confirming that the electrodes of the stimulator are in an abnormal state are constructed for three sub-conditions among the preset conditions, and the three ways of confirming that the electrodes of the stimulator are in an abnormal state are described below. The abnormal state includes a first abnormal state, a second abnormal state, and a third abnormal state.
In one possible implementation manner, the first mode of confirming that the electrode of the stimulator is in an abnormal state is to acquire impedance data of the user, and when judging whether the impedance data is greater than or equal to a preset value, the preset value refers to a value of the human body impedance of the user in a normal range, and the preset value can be determined based on historical impedance data of the user due to different impedance values corresponding to different people. When the impedance value is greater than or equal to the preset value, confirming that the impedance data meets the preset condition, wherein the preset condition is whether the impedance data is greater than or equal to the preset value. When the impedance data meets the preset condition, confirming that the electrode of the stimulator is in a first abnormal state, wherein the abnormal state comprises the first abnormal state. The collected impedance data can be fed back to the energy controller through Bluetooth, so that the energy controller can upload the impedance data to the terminal equipment for analysis.
For example, the preset value may be set to 400 ohms, when the impedance data is 700 ohms, the impedance data is greater than the preset value, and the impedance data of the human body collected by the user is higher than the preset array at this time, so as to confirm that the currently collected impedance data is in the first abnormal state. Because the electrodes are made of conductive materials, when the electrodes are made of copper sheets, the stimulator is medical equipment implanted under skin tissues of a human body, the electrodes in the stimulator are contacted with the human body, and impedance data can be generated by the electrodes. Confirming that the electrode of the stimulator is in a first abnormal state, wherein the first abnormal state is abnormal in electrode position, and the abnormal state comprises the first abnormal state. An abnormal electrode position refers to light abrasion of the electrode, and the position of the electrode can be adjusted to ensure that the electrode can be correctly contacted with a target area. Depending on the characteristics of the electrode wear data, such as the resistance data, the deviation in one direction, the deviation coefficient, is within a certain characteristic range, and the electrode wear may be considered serious or overused.
In addition, when the impedance data is smaller than the preset value, the electrode of the stimulator is confirmed to be in a normal state, and the electrode of the stimulator is continuously monitored.
In a possible implementation manner, a second mode of confirming that electrodes of a stimulator are in abnormal states is adopted, a first using time length of the stimulator is obtained, the first using time length is a working time length of the stimulator, namely, a total time length of normal working of each electrode in the stimulator, 8 electrodes in the stimulator can be arranged, and normal working time length of each electrode can be obtained in sequence. Judging whether the first using time length is greater than or equal to a first preset time length, wherein the first preset time length is the total time length of normal use of each electrode; when the first use time length is longer than or equal to the first preset time length, confirming that the first use time length meets the preset condition, wherein the preset condition is that the first use time length is longer than or equal to the first preset time length, and the electrode of the stimulator is in a second abnormal state, and the abnormal state comprises the second abnormal state. Recording the implantation time of a user for implanting the stimulator, acquiring the serial number of the implanted stimulator, and establishing an implantation time table according to the serial number of the stimulator so as to sequentially record each item of data detected by the stimulator in the table. When determining the implantation time period of the stimulator, the implantation time table of the stimulator is required to be called, and the implantation time period corresponding to the stimulator is determined according to the implantation time and the current time. The implantation time table can be stored in the cloud platform, so that the follow-up data of all aspects can be collected and analyzed conveniently.
The following is an illustration by taking the time of use of any one electrode. When the first use time length of the first electrode in the stimulator is 100 hours, the first preset time length can be set to 90 hours, the first use time length is longer than the first preset time length, the first electrode in the current stimulator is confirmed to be in a second abnormal state, the second abnormal state is abnormal in electrode acquisition, and the abnormal state comprises a second abnormal state. The abnormal electrode collection means that when the first electrode is used, the total using time of the first electrode is equal to the output charge quantity in order to ensure charge balance, but when the first charge is used for a long time, the charge balance is abnormally interrupted due to special reasons, such as power failure, the charges which are not balanced after the power failure can be accumulated, when the charges are accumulated to a certain quantity, the charge imbalance can occur, and the charge imbalance can wear the first electrode. The normal operation of the stimulator can be ensured by adjusting the working period of the first electrode. The first electrode can be reduced from being unable to work normally due to long-time continuous use.
In addition, when the first using time is smaller than the first preset time, the electrode of the stimulator is confirmed to be in a normal state, and the electrode of the stimulator is continuously monitored.
In one possible implementation manner, a third mode of confirming that the electrodes of the stimulator are in an abnormal state is adopted, a second use duration of the stimulator is obtained, the second use duration is a working duration of the stimulator, that is, a total duration of normal working of each electrode in the stimulator, and a normal working duration of each electrode can be obtained in sequence. Judging whether the impedance data is larger than or equal to a preset value and whether the second using time length is larger than or equal to a second preset time length; and when the impedance data is greater than or equal to a preset value and the second using time period is greater than or equal to a second preset time period, confirming that the electrode of the stimulator is in a third abnormal state, wherein the abnormal state comprises the third abnormal state. At this time, the preset condition is that the impedance data is greater than or equal to a preset value, and the second use time period is greater than or equal to a second preset time period. The first use duration and the second use duration refer to the total duration of the operation of each electrode, and the first preset duration and the second preset duration refer to the total duration of the normal use of each electrode.
For example, the preset value may be set to 500 ohms, the second preset duration may be set to 90 hours, the acquisition mode of the human body impedance data of the user a is determined according to the implantation time period of the stimulator implanted by the user a, when the second acquisition mode is used for the user a, the impedance data of the user a is obtained 630 ohms, the use duration of each electrode in the stimulator is obtained, and the total working duration of the first electrode is 95 hours, i.e. the second use duration is 95 hours. When the impedance data is larger than the preset value and the second use time is longer than the second preset time, confirming that the stimulator electrode of the user A is in a third abnormal state, wherein the third abnormal state is a serious abrasion abnormal state of the electrode, and ensuring normal operation of the stimulator by replacing the electrode. Avoiding the influence on the performance and the function of the electrode due to serious abrasion of the electrode.
In addition, when the impedance data is smaller than the preset value and the second use time period is longer than or equal to the second preset time period, the electrode of the stimulator is confirmed to meet the second sub-condition, but not meet the third sub-condition, and the electrode of the stimulator is confirmed to be in the second abnormal state. When the impedance data is larger than or equal to the preset value and the second using time is smaller than the second preset time, the electrode of the stimulator is confirmed to meet the first sub-condition, but not meet the third sub-condition, and the electrode of the stimulator is confirmed to be in the first abnormal state. And when the impedance data is smaller than the preset value and the second using time is smaller than the second preset time, confirming that the electrode of the stimulator is in a normal state, and continuing to monitor the electrode of the stimulator.
Further, in addition to the above three ways, the electrode of the stimulator may be determined to be in an abnormal state, and the above three ways may be arbitrarily combined, and the combined way may also determine whether the electrode of the stimulator is in an abnormal state, specifically how to perform the combination, and may be set according to the actual situation, which is not limited herein specifically.
S204: and displaying the abnormal state through a display screen of the terminal equipment, and prompting a user to replace the electrode.
In S204, after determining that the electrode of the stimulator is in an abnormal state, the abnormal state may be displayed through the display screen of the terminal device, and the user may be prompted to replace the electrode. The user can know the abnormal condition of the electrode in time, the problem that the manual detection process is complicated is solved, and the user experience is improved. Medical staff does not need to carry out a complicated manual detection process, can take measures in time according to the abnormal state of the electrode, and improves detection efficiency and accuracy.
In addition, the abnormal states comprise a first abnormal state, a second abnormal state and a third abnormal state, when the electrode of the stimulator is in the first abnormal state, the first abnormal state is abnormal in electrode position, and the electrode can be adjusted and tested by adjusting the position of the electrode, so that the electrode can be ensured to be in contact with a detection area correctly, and further the normal operation of the stimulator is ensured.
When the electrode of the stimulator is in a second abnormal state, the second abnormal state is abnormal electrode collection, the electrode can be adjusted from a first collection period to a second collection period, the first collection period is the current collection period of the electrode, and the first collection period is larger than the second collection period. For example, the first collection period of the electrode is collected once in 8 days, and the second collection period is set to be collected once in 1 day, so that the first collection period is larger than the second collection period, the collection period is adjusted, and then the normal work of the stimulator is determined. When the acquisition period is determined, different electrodes in the stimulator can be used for acquisition in sequence, so that the problem that one electrode is continuously used for a long time and severely worn is avoided.
When the electrode of the stimulator is in a third abnormal state, the third abnormal state is abnormal in electrode abrasion, and the electrode can be replaced by replacing the electrode, namely the electrode implanted into a human body is replaced by a surgery or other related operations. The treatment modes mentioned in the application are all carried out by a professional doctor or a technician, and patients cannot treat according to abnormal conditions.
