Detailed Description
As described above, when negative pressure cupping treatment is performed, negative pressure is formed in the cupping device and adsorbed on the skin of a user, if negative pressure in the cupping device is large, adverse reactions such as capillary rupture, tissue fluid exudation, skin bleeding, tissue shedding and the like can occur on the skin of the cupping device, tissue necrosis can be easily caused in the later stage, and even cross infection can occur due to incomplete disinfection. In order to monitor the condition of the skin in the cupping device during the negative pressure cupping treatment, the method adopted at present is to detect the negative pressure in the cupping device, judge the condition of the skin in the cupping device according to the negative pressure in the cupping device, and although the condition of the skin in the cupping device has a certain relation with the negative pressure in the cupping device, the skin of different users under the same negative pressure has different conditions due to different tolerance of different individuals, so the condition of the skin in the cupping device cannot be accurately determined according to the negative pressure in the cupping device.
In the embodiment of the invention, when the suction cup is adsorbed on the skin of a user to start negative pressure suction cup treatment on the user, an initial impedance value is calculated according to the impedance value of the skin in the suction cup in an initial period of time, one or more skin impedance thresholds are determined according to the initial impedance value, then the periodically acquired impedance value of the skin in the suction cup is compared with each skin impedance threshold, and the condition of the skin in the suction cup is determined according to the magnitude relation between the acquired impedance value and each skin impedance threshold. Therefore, the skin impedance threshold value for the individual user is determined according to the skin impedance value in the cupping device at the initial stage of negative pressure cupping treatment, and then the skin condition in the cupping device is determined according to the skin impedance threshold value and the acquired impedance value, on one hand, the skin impedance value can directly reflect the skin condition, on the other hand, the skin impedance threshold value is determined for the individual user, and the different individual tolerance is considered, so that the skin condition in the cupping device can be determined more accurately.
The following describes in detail the skin condition monitoring method and apparatus for cupping device according to the embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, one embodiment of the present invention provides a method for monitoring skin conditions in a cupping device, which may include the steps of:
step 101: collecting a negative pressure value in the cupping device once every a preset first collecting period and collecting an impedance value of the skin in the cupping device once every a preset second collecting period from the moment that the cupping device is adsorbed on the skin of a user;
step 102: for at least two preset reference time periods, sequentially calculating average values of at least two negative pressure values acquired in each reference time period according to the sequence of the corresponding time length of the reference time periods from small to large until the average value of the at least two negative pressure values acquired in one reference time period is determined to be positioned in a reference negative pressure range corresponding to the reference time period, and determining the reference time period as a target reference time period, wherein the starting point of the reference time period is the time when the cupping device is adsorbed on the skin of a user, and different reference time periods correspond to different reference negative pressure ranges;
step 103: calculating an initial impedance value according to at least two impedance values acquired in a target reference period;
step 104: determining at least one skin impedance threshold from the initial impedance value;
Step 105: for each impedance value acquired after determining the at least one skin impedance threshold, determining a condition of skin within the cupping device according to a magnitude relation of the impedance value and the at least one skin impedance threshold.
In the embodiment of the invention, in the process of negative pressure cupping treatment, the impedance value of the skin in the cupping device is related to the damage degree of the skin in the cupping device, specifically, the higher the damage degree of the skin is, the smaller the impedance value of the skin is, so that the condition of the skin in the cupping device can be judged according to the impedance value of the skin in the cupping device. However, since the tolerance of different individuals is different, it is necessary to determine a corresponding skin resistance threshold for each user performing the negative pressure cupping treatment, so as to determine whether and to what extent skin damage occurs in the cupping device according to the skin resistance threshold and the resistance value of the skin in the cupping device.
In the embodiment of the invention, the skin impedance threshold is required to be determined according to the initial impedance value of the skin in the cupping device at the initial stage of the negative pressure cupping treatment, namely, the skin of the user is not damaged when the negative pressure cupping treatment is started, and the impedance value of the skin in the cupping device is in a normal range. Because the impedance value of the skin in the cupping device measured for a single time may have fluctuation, in order to ensure that the skin impedance threshold value determined according to the initial impedance value has higher accuracy, the average value of the skin impedance value in the cupping device in a period of time when the negative pressure cupping treatment is started can be used as the initial impedance value.
In the embodiment of the invention, the greater the negative pressure in the cupping device is, the greater the probability of skin damage in the cupping device is, in order to reduce the probability of skin damage of a user due to the greater negative pressure as much as possible, if the negative pressure in the cupping device is greater when the negative pressure cupping treatment is started, the skin impedance threshold value should be determined in a shorter time, so that the skin condition in the cupping device can be monitored according to the skin impedance threshold value as soon as possible, and if the negative pressure in the cupping device is smaller when the negative pressure cupping treatment is started, the time required for determining the skin impedance threshold value can be prolonged appropriately, namely, the skin impedance threshold value is determined according to each skin impedance value acquired in a longer period of time when the negative pressure cupping treatment is started, so that the accuracy of the determined skin impedance threshold value is ensured.
In order to determine the duration of the acquired impedance value required for calculating the skin impedance threshold according to the negative pressure in the cupping device, a plurality of reference time periods are preset, each reference time period has different durations, each reference time period starts to be timed when the cupping device is adsorbed onto the skin of a user, and different reference time periods correspond to different reference negative pressure ranges. When the timing length of one reference period reaches the duration of the reference period, calculating the average value of all the negative pressure values acquired in the reference period, if the calculated average value is positioned in the reference negative pressure range corresponding to the reference period, determining the reference period as a target reference period, further calculating the skin impedance threshold according to the impedance value acquired in the target reference period, and then, not timing other reference periods, if the calculated average value is not positioned in the reference negative pressure range corresponding to the reference period, continuing to time each subsequent reference period until the timing length of the next reference period reaches the corresponding duration, and processing the next reference period in the same mode as the above until the target reference period is determined.
In an embodiment of the present invention, after determining the target reference period, an initial impedance value is calculated from each impedance value acquired during the target reference period, and then one or more skin impedance thresholds are determined from the calculated initial impedance values. After the skin impedance threshold is obtained, each time an impedance value is acquired, the acquired impedance value is compared with each skin impedance threshold, and the condition of the skin in the cupping device is determined according to the magnitude relation between the impedance value and each skin impedance threshold.
In the embodiment of the invention, after the cupping device is adsorbed on the skin of a user, the negative pressure value in the cupping device and the impedance value of the skin in the cupping device are collected according to a preset period, a period of time from the adsorption of the cupping device on the skin of the user is determined according to the negative pressure value in the cupping device and is used as a target reference period, the skin impedance threshold value is determined according to each acquired impedance value in the target reference period, then the newly acquired impedance value can be compared with the skin impedance threshold value, and the condition of the skin in the cupping device is determined according to the size relation between the impedance value and the skin impedance threshold value. On one hand, the skin impedance value and the damage degree of the skin have a specific relation, and on the other hand, the skin impedance threshold value is determined according to the skin impedance value in the cupping device at the initial stage of negative pressure cupping treatment, so that the condition of the skin in the cupping device is determined according to the skin impedance threshold value determined for a user individual and the skin impedance value in the cupping device, and the condition of the skin in the cupping device can be monitored more accurately.
Optionally, on the basis of the method for monitoring skin conditions in the cupping device shown in fig. 1, a first acquisition period for periodically acquiring a negative pressure value in the cupping device and a second acquisition period for periodically acquiring an impedance value of skin in the cupping device are preset, where the first acquisition period and the second acquisition period may be the same or different.
In the embodiment of the invention, when the first acquisition period is the same as the second acquisition period, the negative pressure value in the cupping device and the impedance value of the skin in the cupping device are acquired according to the same frequency, so that the acquisition process of the negative pressure value and the impedance value can be more conveniently controlled, the number of the negative pressure values and the impedance values acquired in the same time period is the same, and the average value of the negative pressure values acquired in each reference period and the initial impedance value according to the various impedance values acquired in the target reference period are conveniently calculated.
For example, the first acquisition period and the second acquisition period are both set to 1s in advance, that is, the negative pressure value in the cupping device and the impedance value of the skin in the cupping device are acquired once every 1s from the time when the cupping device is adsorbed onto the skin of a user.
It should be noted that, the collection mode of the negative pressure value in the cupping device and the collection mode of the skin impedance value in the cupping device do not belong to the technical content to be protected in the invention, specifically, the negative pressure value in the cupping device and the skin impedance value in the cupping device can be collected by adopting the existing mode, and the negative pressure value in the cupping device and the skin impedance value in the cupping device can also be collected by adopting the innovative mode. For example, a pressure sensor with a wireless communication function can be arranged in the cupping device to collect negative pressure values in the cupping device, and an impedance collecting circuit with a wireless communication function can be arranged in the cupping device to collect impedance values of skin of the cupping device.
Optionally, on the basis of the skin condition monitoring method in the cupping device shown in fig. 1, a plurality of reference time periods with different durations are preset, and different reference time periods correspond to different reference negative pressure ranges. For any one of the first reference period and one second reference period of the set reference periods, if the time length of the first reference period is longer than the time length of the second reference period, the maximum reference negative pressure value of the reference negative pressure range corresponding to the first reference period is smaller than the minimum reference negative pressure value of the reference negative pressure range corresponding to the second reference period.
In the embodiment of the invention, different reference negative pressure ranges corresponding to different reference time periods are provided, so that in order to determine the unique target reference time period, the reference negative pressure ranges corresponding to the reference time periods should not overlap, and the sum of the reference negative pressure ranges corresponding to the reference time periods can cover all possible intervals of the negative pressure average value. For example, on the premise that the first acquisition period and the second acquisition period are both 1s, 5 reference periods are preset, and reference negative pressure ranges corresponding to the 5 reference periods are shown in the following table 1.
TABLE 1
| Reference period of time | Reference period 1 | Reference period 2 | Reference period 3 | Reference period 4 | Reference period 5 |
| Reference negative pressure range | ≤30 | More than 30 and less than or equal to 40 | More than 40 and less than or equal to 50 | More than 50 and less than or equal to 60 | ＞60 |
| Duration of time | 120s | 100s | 60s | 30s | 20s |
| Number of negative pressure values | 120 | 100 | 60 | 30 | 20 |
| Quantity of impedance values | 120 | 100 | 60 | 30 | 20 |
For the reference period and the settings of the first and second acquisition periods shown in table 1, after the cupping device is adsorbed on the skin of the user, the 5 reference periods start to be timed, when the timing duration is equal to 20s, the timing of the reference period 5 is completed, the average value of 20 negative pressure values acquired in the reference period 5 is calculated, if the calculated average value is greater than 60, the reference period 5 is determined as the target reference period, the other 4 reference periods stop to be timed, and if the calculated average value is less than or equal to 60, the other 4 reference periods continue to be timed. And after the timing of one reference period is finished, judging whether the average value of all the negative pressure values acquired in the reference period is in the reference negative pressure range corresponding to the reference period, if so, determining the reference period as a target reference period, stopping timing of other unfinished timing reference periods, and if not, continuing timing of other unfinished timing reference periods until the target reference period is determined.
For the reference period and the first and second acquisition periods shown in table 1, since the reference negative pressure range corresponding to the reference period 5 is greater than 60, the probability of skin damage caused by the greater negative pressure value is greater, so that the skin impedance threshold needs to be determined as soon as possible, the duration corresponding to the reference period 5 is only 20s, the reference negative pressure range corresponding to the reference period 1 is less than or equal to 30, the probability of skin damage caused by the smaller negative pressure value is smaller, so that the time for acquiring the impedance value and the negative pressure value can be prolonged to ensure that the determined skin impedance threshold has higher accuracy, and the duration corresponding to the reference period 1 reaches 120s.
Alternatively, on the basis of the skin condition monitoring method in the cupping device shown in fig. 1, after the target reference period is determined, an average value of the respective impedance values acquired in the target reference period may be calculated, and the calculated average value may be used as the initial impedance value.
In the embodiment of the invention, since the target reference period is a period of time when the cupping device is adsorbed on the skin of the user at the beginning, the skin of the user is not damaged yet because the cupping device is just adsorbed on the skin of the user, and the initial impedance value is determined according to the impedance value of the skin in the cupping device at the moment, so that the skin impedance threshold determined based on the initial impedance value can be ensured to more accurately demarcation the condition of the skin in the cupping device. In addition, the average value of all the impedance values acquired in the target reference period is used as an initial impedance value, so that the condition that a large error exists in the impedance value acquired in a single time is eliminated, and the accuracy of the determined initial impedance value can be further ensured.
Optionally, on the basis of the skin condition monitoring method in the cupping device shown in fig. 1, when the skin impedance threshold is performed according to the initial impedance value, specifically, a product of the initial impedance threshold and a first preset coefficient is taken as a first skin impedance threshold, and a product of the initial impedance threshold and a second preset coefficient is taken as a second skin impedance threshold, where the first preset coefficient and the second preset coefficient are both greater than zero and less than 1, and the first preset coefficient is greater than the second preset coefficient.
