The embodiment of the present invention provides an information feedback method, wherein each surgical site is set to correspond to at least one group of electrodes; the connection position of each group of electrodes is determined, and the connection between the two electrodes in each group of electrodes is connected with the The surgical site corresponding to the electrodes is in contact; the impedance threshold range corresponding to each group of electrodes is determined, and the current impedance value corresponding to each group of electrodes is obtained; when it is detected that the current impedance value corresponding to any group of electrodes is not within the corresponding impedance threshold range When , determine the abnormality report information corresponding to this group of electrodes; output the abnormality report information and carry out abnormality processing. According to each group of electrodes corresponding to the surgical site, by monitoring the impedance changes of each group of electrodes, the recovery effect of the surgical site can be monitored in real time, so that when the monitoring of the poor recovery effect of the surgical site is detected, timely treatment can be performed to ensure the safety of patients after surgery. Therefore, the embodiment of the present invention can timely process the surgical site with poor recovery effect.

In an embodiment of the present invention, in order to illustrate an electrode connection method, the electrode includes: one end includes an adhesive layer, and the other end includes an electrode with an alternating voltage joint;

The method further includes: connecting the alternating voltage connections of two electrodes in each group of electrodes to two supply voltage ports in a group of alternating voltage ports of the transformer, respectively;

Determining the connection positions of each group of electrodes and contacting the connection line between the two electrodes in each group of electrodes with the surgical site corresponding to the group of electrodes includes: determining two connection positions of each group of electrodes, wherein , each of the connection positions is located on the skin surface near the surgical site corresponding to the group of electrodes, and the shortest connecting line between the two connection positions is in contact with the surgical site corresponding to the group of electrodes; The adhesive layers of the electrodes are respectively adhered at the two determined connection positions, wherein the minimum distance between each of the connection positions and the corresponding outer edge of the surgical site is between 0 and 10 cm.

In one embodiment of the present invention, the transformer can convert the 220V voltage of the peripheral power supply system into a voltage that the human body can withstand.

In detail, since the human body is a conductor, for each set of electrodes, when one end of the two electrodes is respectively adhered to the two connection positions on the surface of the human body, and the other ends of the two electrodes are respectively connected with the transformer's When two voltage supply ports in a group of alternating voltage ports are connected, a closed circuit can be formed, and the body part between the two electrodes is equivalent to an electrical impedance. Wherein, when the blood flow at the body part is smooth, the electrical impedance is relatively small, and when the blood flow is blocked, the electrical impedance is relatively large.

Therefore, when the transformer outputs voltage to two voltage supply ports in a group of alternating voltage ports, current will flow through the body part between the two electrodes connected to the two voltage supply ports. Wherein, when the output voltage is fixed, the magnitude of the current is inversely proportional to the electrical impedance at the body part, and both are related to the blood flow state at the body part.

In this embodiment of the present invention, the same surgical site may correspond to multiple groups of electrodes, and the connection positions of each group of electrodes are different. Since there are usually differences in the blood flow direction, blood flow velocity, etc. between different groups of electrodes, the blood flow state between each group of electrodes may be different, resulting in different impedance values between each group of electrodes. Therefore, for each group of electrodes, when the current impedance value corresponding to the group of electrodes is monitored in real time, in order to be able to judge the blood flow state at the corresponding surgical site according to the current impedance value, on the one hand, each group of electrodes can be determined. The initial impedance value corresponding to the electrodes, on the other hand, the impedance threshold range corresponding to each group of electrodes can be determined.

In detail, for the determination of the initial impedance value:

In one embodiment of the present invention, in the initial stage of recovery after a patient's operation, the blood flow at the operation site is usually normal, that is, there is usually no thrombosis or bleeding symptoms. The impedance value calculated from the current value or voltage value is used as the initial impedance value, and the initial impedance value can be the comparison standard for each current impedance value afterward.

Of course, in an embodiment of the present invention, the average value of multiple impedance values initially calculated when each group of electrodes is initially connected to the corresponding connection position can also be recorded as the initial impedance value, and used as the value of each current impedance value thereafter. Compare standard.

In detail, for the determination of the impedance threshold range:

In this embodiment of the present invention, the impedance threshold range may be determined in at least the following two implementation manners, and each of the manners corresponds to a different judgment manner for judging the current impedance value according to the impedance threshold range, as described in detail as follows:

Method A: The impedance threshold range is a standard comparison range based on the initial impedance value. When it is determined that the current impedance value is not within the standard comparison range, it means that the surgical site is abnormal;

Mode B: The impedance threshold range is the initial impedance value, which is used as a standard threshold value. When it is determined that the current impedance value obtained multiple times in a row is greater than or less than the standard threshold value, it means that the surgical site is abnormal.

In detail, for the above method A:

In an embodiment of the present invention, the determining an impedance threshold range corresponding to each group of electrodes includes: for each group of electrodes, determining an initial impedance value of the group of electrodes; and determining a corresponding impedance threshold according to the initial impedance value The range is (R _min , R _max ),

Wherein, R _min =K ₁ ×R ₀ , R _max =K ₂ ×R ₀ , and R ₀ is the initial impedance value, K ₁ is any value in the range of 0.85-0.90; K ₂ is any value in the range of 1.05-1.10 any value.

In an embodiment of the present invention, the value ranges of K ₁ and K ₂ can be adjusted according to the requirements of different practical application scenarios.

Since the blood flow state at the surgical site can vary slightly, the current monitored impedance value may fluctuate slightly compared to the initial impedance value, but these small changes or fluctuations usually do not cause thrombosis or bleeding at the surgical site Therefore, an appropriate impedance threshold range can be determined based on the initial impedance value corresponding to each group of electrodes. As long as the monitored current impedance value is within the impedance threshold range, it can be considered that the current blood flow state of the surgical site is normal.

In detail, the judgment rule for the current impedance value may be: for each group of electrodes, when the current impedance value of the group of electrodes is lower than the corresponding impedance threshold range, it is determined that bleeding occurs at the surgical site; the current impedance value of the group of electrodes is higher than the corresponding impedance threshold range. When the current impedance value of the group of electrodes is within the corresponding impedance threshold range, it is determined that the blood flow at the surgical site is normal.

In detail, for the above-mentioned way B:

In an embodiment of the present invention, the determining the impedance threshold range corresponding to each group of electrodes includes: for each group of electrodes, determining an initial impedance value of the group of electrodes, and the initial impedance value is the impedance corresponding to the group of electrodes threshold;

When it is detected that the current impedance value corresponding to any group of electrodes is not within the corresponding impedance threshold range, the abnormal report information corresponding to the group of electrodes is determined, including: for each group of electrodes, when the group of electrodes is continuously monitored at least once When the current impedance values corresponding to the electrodes are all smaller than the impedance threshold corresponding to the electrodes of the group, it is determined that the abnormal report information corresponding to the electrodes of the group is bleeding at the surgical site; When the impedance threshold corresponding to the electrodes of the group is determined, the abnormal report information corresponding to the electrodes of the group is determined to be thrombosis at the surgical site.

In an embodiment of the present invention, according to the requirements of different practical application scenarios, the number of times that the current impedance value is continuously monitored is greater than or less than the corresponding impedance threshold value can be adjusted, for example, it can be set to 5 times, 10 times, 30 times any of the following. Wherein, the longer the time interval between two monitoring operations, the less the number of settings can be relatively. By setting the appropriate time interval and the corresponding number of times, the effect of accurate judgment and timely processing can be achieved.

In detail, the judgment rule for the current impedance value may be: for each group of electrodes, when the current impedance value of the group of electrodes is lower than the corresponding impedance threshold for several consecutive times, it is determined that bleeding occurs at the surgical site; the current impedance value of the group of electrodes is determined to be bleeding. When the impedance is higher than the corresponding impedance threshold for several consecutive times, it is determined that a thrombus occurs at the surgical site; in any other situation except the above two cases, it is determined that the blood flow at the surgical site is normal.

It can be seen from the above content that, according to the monitored current impedance value, the blood flow state of the surgical site can be reflected, that is, the postoperative recovery of the surgical site can be reflected.

In detail, for each group of electrodes, when the output voltage between the two pressure supply ports corresponding to the group of electrodes is fixed, if bleeding occurs at the surgical site corresponding to the group of electrodes, the blood flow is enhanced, so the surgical site is The impedance value of the surgical site decreases, resulting in an increase in the current value; if a thrombus occurs at the surgical site, the blood flow decreases, so the impedance value at the surgical site increases, resulting in a decrease in the current value; if the blood flow at the surgical site is normal, Then the impedance value at the surgical site is usually constant, so the current value does not change.

Correspondingly, based on the same implementation principle, for each group of electrodes, when the input current between the two pressure supply ports corresponding to the group of electrodes is fixed, the magnitude of the voltage value can be related to the blood flow state at the surgical site.

Therefore, the current impedance value at the surgical site can be determined according to the measured current value or voltage value, thereby reflecting the blood flow state at the surgical site. Based on this implementation, the recovery of the surgical site can be monitored by monitoring the blood flow state at the surgical site during the initial postoperative recovery of the patient.

From the above, there are at least two possible implementations for determining the current impedance value at the surgical site:

Mode 1: The voltage value is fixed, and the current impedance value is determined according to the monitored current value;

Mode 2: The current value is fixed, and the current impedance value is determined according to the monitored voltage value.

In detail, for the above method 1:

In an embodiment of the present invention, the acquiring the current impedance value corresponding to each group of electrodes includes: outputting a fixed voltage to each group of electrodes, and collecting the current current value corresponding to each group of electrodes in real time; according to the formula R _i = U/I _i , calculate the current impedance value corresponding to each group of electrodes,

Wherein, R _i is the current impedance value, U is the fixed voltage, and I _i is the current current value.

In this embodiment, since the voltage is fixed, the current monitored current value and the current impedance value calculated according to the current current value are inversely proportional.

In detail, for the above-mentioned way 2:

In an embodiment of the present invention, the acquiring the current impedance value corresponding to each group of electrodes includes: inputting a fixed current to each group of electrodes, and collecting the current voltage values across each group of electrodes in real time; according to the formula R _i = U _i /I, calculate the current impedance value corresponding to each group of electrodes,

Wherein, R _i is the current impedance value, U _i is the fixed current, and I is the current voltage value.

In this embodiment, since the current is fixed, the monitored current voltage value is proportional to the current impedance value calculated according to the current voltage value.

In addition, in an embodiment of the present invention, the comparison between the current impedance value and the initial impedance value may not be performed, and the blood flow state at the surgical site may also be determined to monitor the recovery of the surgical site. For example, when the output voltage corresponding to each group of electrodes is fixed, if the current value of the current corresponding to the group of electrodes monitored multiple times in a row is higher than the corresponding initial current value, it means that the surgical site corresponding to the group of electrodes has hemorrhage. ; If the current current value corresponding to the group of electrodes monitored multiple times in a row is lower than the corresponding initial current value, it means that the operation site corresponding to the group of electrodes has thrombosis; otherwise, it means that the blood flow at the operation site is normal. Correspondingly, when a fixed current is input to each group of electrodes, if the current voltage value monitored several times in a row is higher than the initial voltage value, it means that thrombosis occurs at the surgical site; if the current voltage value monitored several times in a row is higher than the initial voltage value If the values are all lower, it means the bleeding at the surgical site; otherwise, the blood flow at the surgical site is normal.

In the embodiment of the present invention, when an abnormal current impedance value corresponding to any group of electrodes is monitored, it indicates that there may be bleeding or thrombosis symptoms in the surgical site corresponding to the group of electrodes, so relevant doctors and nurses can be notified for timely treatment, so it is necessary to Determine the abnormal report information corresponding to this group of electrodes.

In an embodiment of the present invention, the abnormality report information includes at least one of: the identification of the surgical site corresponding to the group of electrodes, the abnormal symptoms corresponding to the group of electrodes, and the current time,

Wherein, when the current impedance value of the group of electrodes is lower than the corresponding impedance threshold range, the abnormal symptom is bleeding at the surgical site, and when the current impedance value of the group of electrodes is higher than the corresponding impedance threshold range, the abnormal symptom is surgery. Thrombosis at the site.

By determining the abnormality report information, it is possible to quickly know which surgical site of the patient is abnormal, the specific abnormality of the surgical site, and the discovery time of the abnormality in the surgical site.

In detail, after the abnormality report information corresponding to the abnormal operation site is determined, the abnormality report information can be sent to the nurse station and the attending doctor of the patient. Therefore, in an embodiment of the present invention, outputting the abnormality report information and performing abnormality processing includes: according to the pre-established correspondence between different patient information and the identification of different surgical sites, and the identification of different surgical sites and The corresponding relationship between the identifiers of different groups of electrodes, determine the patient information corresponding to the group of electrodes that are currently abnormal; send the abnormality report information and the determined patient information to the nurse station through GPRS, and/or the attending doctor corresponding to the patient. pregnancy.

Since there are usually many patients in the hospital every day, the unique number of each patient, the contact information of the attending doctor of the patient, the unique identification of each surgical site of the patient, and the electrodes corresponding to each surgical site can be determined in advance. The unique identification of each patient, and the basic information of each patient is archived and stored. Based on this implementation, when an abnormality of any group of electrodes is monitored, the basic information of the patient corresponding to the current abnormal group of electrodes can be determined, and the determined patient information and abnormality report information can be sent to the nurse station and the corresponding attending doctor pregnancy.

In detail, the basic information of the patient may include name, age, gender, hospitalization time, operation time, operation condition, postoperative condition, and the like.

In addition, since the above-determined abnormal report information only specifies the specific measurement results, and does not involve the detailed recovery of the surgical site during the postoperative recovery process, in order to facilitate doctors and nurses to understand the detailed recovery of the abnormal surgical site, this In an embodiment of the invention, the determining of the abnormality report information corresponding to the group of electrodes includes: acquiring each impedance value corresponding to the group of electrodes, and generating a corresponding waveform diagram according to each acquired impedance value;

The outputting the abnormality report information and performing the abnormality processing includes: outputting the waveform diagram to a display in the nurse station, and triggering an alarm device in the nurse station to give an alarm reminder.

By converting each impedance value into a corresponding waveform, the medical staff can quickly and directly understand the abnormal situation of the patient's surgical site. In addition, since the symptoms of bleeding and thrombosis at the surgical site are serious and urgent, the alarm device in the nurse station can be triggered to give an alarm reminder.

As shown in FIG. 2, an embodiment of the present invention provides another information feedback method. The method takes monitoring the postoperative recovery status of a patient's surgical site as an example, and specifically includes the following steps:

Step 201: Set the surgical site to correspond to 2 groups of electrodes, and each group of electrodes includes 2 electrodes.

In detail, one end of the electrode includes an adhesive layer, and the other end includes an alternating voltage connection. Wherein, the adhesive layer of the electrode can be in contact with the skin on the surface of the human body, and the alternating voltage joint of the electrode can be connected to the voltage supply port of the transformer.

In this embodiment, the surgical site may be a wound on the patient's leg, and the surgical site may correspond to two sets of electrodes, electrode set 1 and electrode set 2 . The numbers of the two electrodes included in the electrode group 1 may be 001 and 002, and the numbers of the two electrodes included in the electrode group 2 may be 003 and 004.

In this embodiment, the transformer may include multiple groups of alternating voltage ports, and each group of alternating voltage ports is connected to a group of electrodes. For example, the electrode group 1 corresponds to the alternating voltage port 1, and the electrode group 2 corresponds to the alternating voltage port 2. The two voltage supply ports included in the alternating voltage port 1 are port a and port b, and the two voltage supply ports included in the alternating voltage port 2 are port c and port d.

Therefore, it is possible to connect the alternating voltage connection of electrode 001 to port a, the alternating voltage connection of electrode 002 to port b, the alternating voltage connection of electrode 003 to port c, and the alternating voltage connection of electrode 004 to port d connected. Therefore, when the transformer outputs a fixed voltage between each group of alternating voltage ports, the electrode 001, the surgical site, the electrode 002, the port b, and the port a can form a current loop. Correspondingly, the electrode 003, the surgical site, the electrode 004, the port d, and the port c can form a current loop.

Step 202: Determine the connection position of each group of electrodes, and contact the connection line between two electrodes in each group of electrodes with the surgical site corresponding to the group of electrodes.

In one embodiment of the present invention, the connection positions of the electrodes can be determined as follows: the connection position of the electrode 001 is directly above the surgical site, the connection position of the electrode 002 is directly below the surgical site, and the connection position of the electrode 003 is the surgical site Right to the left of the electrode 004, the connection position of the electrode 004 is to the right of the surgical site, wherein each connection position is located on the surface of the human skin, and the minimum distance between each connection position and the outer edge of the surgical site is 5cm.

In detail, the adhesive layer of each electrode may be adhered to the human skin surface at the corresponding connection location.

In detail, in order to use electrode set 1 and electrode set 2 to monitor the blood flow of the surgical site respectively, the shortest connection between the connection positions of electrode 001 and electrode 002 can be in contact with the surgical site, and the connection between electrode 003 and electrode 004 The shortest connecting line between the connecting locations can make contact with the surgical site.

Step 203: For each group of electrodes, determine an initial impedance value of the group of electrodes, and determine a corresponding impedance threshold range according to the initial impedance value.

In detail, since the voltage corresponding to each group of electrodes is fixed, the current current value corresponding to each group of electrodes can be collected in real time, and the current impedance value corresponding to each group of electrodes can be calculated according to the formula R _i =U/I _i ,

Among them, R _i is the current impedance value, U is the fixed voltage, and I _i is the current current value.

During the initial postoperative recovery period at the surgical site, blood flow at the surgical site is usually normal, and there are no symptoms such as bleeding or blood clots. Therefore, the first impedance value calculated, or the average value of the first several impedance values calculated can be recorded as the initial impedance value. For example, the initial impedance value of electrode group 1 is R _0-1 , and the initial impedance value of electrode group 1 is R _0-2 .

In detail, according to the initial impedance value, the corresponding impedance threshold range can be determined as (R _min , R _max ), where R _min =K ₁ ×R ₀ , R _max =K ₂ ×R ₀ , and R ₀ is the initial impedance value, K ₁ is any value from 0.85 to 0.90; K ₂ is any value from 1.05 to 1.10.

Therefore, for example, it can be determined that the impedance threshold range of electrode group 1 is (0.90×R _0-1 , 1.10×R _0-1 ), and the impedance threshold range of electrode group 2 is (0.90×R _0-2 , 1.10× R _0-2 ).

Step 204: Acquire the current impedance value corresponding to each group of electrodes.

From the above, according to the fixed voltage value, when each current current value is acquired, the corresponding current impedance value can be calculated.

Step 205 : when it is detected that the current impedance value corresponding to any group of electrodes is not within the corresponding impedance threshold range, determine the abnormality report information corresponding to the group of electrodes.

In detail, the abnormality report information may include: at least one of the identification of the surgical site corresponding to the group of electrodes, the abnormal symptoms corresponding to the group of electrodes, and the current time,

Wherein, when the current impedance value of the group of electrodes is lower than the corresponding impedance threshold range, the abnormal symptom is bleeding at the surgical site, and when the current impedance value of the group of electrodes is higher than the corresponding impedance threshold range, the abnormal symptom is thrombosis at the surgical site.

For example, since the newly acquired current impedance value of electrode group 1 is not within the range of (0.90×R _0-1 , 1.10×R _0-1 ) and is less than 0.90×R _0-1 , it is necessary to determine electrode group 1 Corresponding exception information. Among them, the abnormal symptom in the abnormal information is bleeding.

Step 206: Determine the patient information corresponding to the electrode group 1 according to the pre-established correspondence between the different patient information and the identifiers of different surgical sites, and the correspondence between the identifiers of different surgical sites and the identifiers of different groups of electrodes.

In detail, the patient information may include name, age, gender, hospitalization time, operation time, operation condition, postoperative condition, and the like.

Step 207: Acquire each impedance value corresponding to the electrode group 1, and generate a corresponding waveform diagram according to each acquired impedance value.

By converting each impedance value into a corresponding waveform, the medical staff can quickly and directly understand the abnormal situation of the patient's surgical site.

Step 208: Send the determined abnormal report information and patient information to the nurse station and the attending doctor corresponding to the patient through GPRS, and output the generated waveform to the display in the nurse station, and trigger the alarm device in the nurse station to perform the operation. Alarm reminder.

Because the bleeding and thrombosis symptoms at the surgical site are usually serious and urgent, in addition to sending abnormal report information and patient information to the nurse station and the corresponding attending doctor in a timely manner, the alarm device in the nurse station can also be immediately triggered to give an alarm reminder.
