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 the negative pressure in the cupping device is large, capillary rupture, tissue fluid exudation, skin bleeding and tissue shedding may occur in the skin of the cupping device, adverse reactions such as tissue necrosis are easily caused in the later stage, and even cross infection caused by incomplete disinfection may be caused. Because different users have different tolerance to negative pressure, whether the negative pressure in the cupping device is safe and effective cannot be determined according to the magnitude of the negative pressure in the cupping device, and adverse reactions of skin in the cupping device and the impedance of skin in the cupping device are related, particularly, the skin impedance is smaller as the adverse reactions of skin are more serious, so that whether the negative pressure in the cupping device is safe and effective can be determined by detecting the impedance of the skin in the cupping device. However, since the cupping device is adsorbed on the skin of the user, the existing skin impedance acquisition device cannot extend into the cupping device to detect the impedance of the skin, so that whether the negative pressure in the cupping device is suitable for the corresponding user or not cannot be judged according to the skin impedance in the cupping device, namely whether the negative pressure in the cupping device is safe and effective or not cannot be determined according to the skin impedance in the cupping device.

In the embodiment of the invention, the impedance acquisition sheet is formed by the substrate and the conductive electrode arranged on the substrate, the surface of the substrate is adhered to the inner wall of the cup body of the tube cup through back glue, the first end of the substrate is flush with the mouth of the cup, the second end of the substrate is connected with the acquisition component, the acquisition component is fixed in the cup, and the conductive electrode on the substrate is connected with the impedance detection circuit in the acquisition component. When the cupping device is adsorbed on the skin of a user, the skin of the user is contacted with the conductive electrode on the first end of the substrate, so that the impedance detection circuit and the skin of the user form a loop, the impedance detection circuit can detect the skin impedance value of the skin in the cupping device, and then the processor can send the skin impedance value detected by the impedance detection circuit to an external monitoring host computer in a wireless communication mode through the bronze drum wireless communication module, so that the monitoring host computer can determine whether the negative pressure in the cupping device is suitable for the user according to the skin impedance value, and whether the negative pressure in the cupping device is safe and effective or not is judged according to the skin impedance in the cupping device.

The skin impedance acquisition device, the skin impedance acquisition method and the negative pressure monitoring system in the cupping device provided by the embodiment of the invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, one embodiment of the present invention provides a skin impedance collecting apparatus including an impedance collecting piece 10 and a collecting member 20;

the acquisition component 20 comprises an impedance detection circuit 21, a processor 22 and a wireless communication module 23, wherein the processor 22 is respectively connected with the impedance detection circuit 21 and the wireless communication module 23;

The impedance acquisition piece 10 comprises a substrate 11 and at least two conductive electrodes 12, wherein each conductive electrode 12 is arranged on the front surface of the substrate 11, and each conductive electrode 12 is parallel to each other and extends from a first end of the substrate 11 to a second end of the substrate 11;

The back of the substrate 11 is adhered to the inner wall of the cup body of the cup 30 through back glue, the first end of the substrate 11 is flush with the cup mouth of the cup 30, and the second end of the substrate 11 is connected with the collecting component 20 so as to fix the collecting component 20 in the cup 30 and connect each conductive electrode 12 with the impedance detection circuit 21;

When the cupping device 30 is adsorbed on the skin 40 of the user, the skin 40 of the user is contacted with each conductive electrode 12 at the first end of the substrate 11, so that the skin 40 of the user and the impedance detection circuit 21 form a loop, the impedance detection circuit 21 detects the skin impedance value of the skin 40 and sends the detected skin impedance value to the processor 22;

after receiving the skin impedance value from the impedance detection circuit 21, the processor 22 sends the received skin impedance value to the external monitoring host 50 in a wireless communication manner through the wireless communication module 23, so that the monitoring host 50 determines the adaptability between the negative pressure in the cupping device 30 and the skin 40 according to the skin impedance value.

In the embodiment of the invention, the front surface of the substrate 11 is provided with the conductive electrode 12, while the back surface of the substrate 11 can be adhered to the inner wall of the cup body of the cup 30 through back glue, the first end of the substrate 11 is flush with the mouth of the cup 30, and the second end of the substrate 11 is connected with the collecting member 20, so that the impedance collecting piece 10 and the collecting member 20 can be fixed in the cup 30, and the conductive electrode 12 is connected with the impedance detecting circuit 21. When the cupping device 30 is adsorbed on the skin 40 of the user, the skin 40 of the user enters the cupping device 30 to be contacted with each conductive electrode 12 on the first end of the substrate 11, so that the skin 40 of the user and the impedance detection circuit 21 form a loop, the impedance detection circuit 21 can detect the skin impedance value of the skin 40 in the cupping device 30, and then the processor 22 can send the skin impedance value detected by the impedance detection circuit 21 to the external monitoring host 50 in a wireless communication mode through the wireless communication module 23, so that the monitoring host 50 determines whether the negative pressure in the cupping device 30 is suitable for the user according to the skin impedance value. It can be seen that the collecting member 20 can collect the skin impedance value of the skin 40 in the cupping device 30 through the impedance collecting tab 10 and transmit the detected skin impedance value to the monitoring host 50 located outside the cupping device 30 through wireless communication, and the monitoring host 50 can determine whether the negative pressure in the cupping device 30 is suitable for the user according to the received skin impedance value, thereby determining whether the negative pressure in the cupping device 30 is safe and effective according to the skin impedance in the cupping device 30.

Optionally, on the basis of the skin impedance acquisition device shown in fig. 2, as shown in fig. 3, the acquisition component 20 further comprises a pressure sensor 24 and a pressure signal processor 25;

The pressure sensor 24 is connected with the pressure signal processor 25, and the pressure signal processor 25 is connected with the processor 22;

When the cupping glass 30 is adsorbed on the skin 40 of the user, the pressure sensor 24 may detect the pressure inside the cupping glass 30, obtain a first pressure signal according to the detected pressure, and transmit the obtained first pressure signal to the pressure signal processor 25;

The pressure signal processor 25 may amplify and compensate the first pressure signal to obtain a second pressure signal, and transmit the obtained second pressure signal to the processor 22;

The processor 22 may send the second pressure signal to the monitoring host 50 through the wireless communication module 23 in a wireless communication manner, so that the monitoring host 50 displays the pressure in the cupping device 30 according to the second pressure signal, and the monitoring host 50 determines the suitability between the negative pressure in the cupping device 30 and the skin condition according to the received skin impedance value and the second pressure signal.

In the embodiment of the present invention, the pressure sensor 24 may collect the pressure in the cupping device 30, and the collected strong pressure is sent to the monitoring host 50 after being processed by the signal, so that the monitoring host 50 may display the pressure in the cupping device 30, so that a user may conveniently determine the pressure in the cupping device 30, in addition, the monitoring host 50 may determine whether the negative pressure in the cupping device 30 is suitable by combining the pressure in the cupping device 30 and the impedance of the skin in the cupping device 30, so as to ensure that whether the negative pressure in the cupping device 30 is suitable for the skin of the user can be more accurately determined.

The pressure sensor 24 may be an absolute negative pressure type pressure sensor, and the maximum nominal value of the negative pressure is 50-100kpa, and since the pressure sensor 24 is disposed in the cupping device 30 having the negative pressure, it is necessary to detect the pressure difference between the inside and the outside of the cupping device 30 and one atmosphere pressure, and thus a sensor (absolute pressure sensor) having one atmosphere pressure inside is selected as the pressure sensor 24.

In the embodiment of the present invention, after the pressure sensor 24 forms the first pressure signal according to the pressure in the cupping device 30, the pressure signal processor 25 may amplify and compensate the first pressure signal. The amplifying process mainly amplifies the first pressure signal to make the obtained second pressure signal more clearly reflect the pressure in the cupping device 30, and the compensating process mainly comprises precision compensation and temperature compensation for the first pressure signal, wherein the pressure is influenced by factors such as temperature, and the second pressure signal can more accurately reflect the pressure in the cupping device 30 by performing precision compensation and temperature compensation for the first pressure signal.

The pressure signal processor 25 amplifies and compensates the first pressure signal to obtain a second pressure signal, so that the second pressure signal can more clearly and accurately reflect the pressure in the cupping device 30, and further the monitoring host 50 can accurately display the pressure in the cupping device 30, and the accuracy of judging whether the negative pressure in the cupping device 30 is suitable for a user can be improved.

In the embodiment of the present invention, since the collecting member 20 is fixed in the cupping device 30 in use, and the thermal prototype cupping device which relies on consuming oxygen in the canister to achieve adsorption has a short high temperature in use, the collecting member 20 is in contact with the high Wen Duanzan. In order to avoid the damage of the collecting component 20 caused by short-term contact with high temperature, the impedance detection circuit 21, the processor 22, the wireless communication module 23 and other components included in the collecting component 20 are arranged in a housing made of high-temperature resistant polymer material, when the collecting component 20 is in short-term contact with high temperature, the housing made of high-temperature resistant polymer material can insulate heat to protect each component arranged in the housing, so that the collecting component 20 is prevented from being damaged due to short-term contact with high temperature.

In addition, the shell of the collecting part 20 is made of high-temperature resistant polymer materials, so that the collecting part 20 is not damaged due to short-time contact with high temperature, and the collecting part 20 can be ensured to have smaller weight due to the smaller density of the polymer materials, and the collecting part 20 is conveniently fixed in the cupping device 30.

In an embodiment of the present invention, the processor 22 is configured to perform overall coordination and processing of the other various modules within the acquisition component 20.

As shown in FIG. 7, one embodiment of the present invention provides an intra-cupping device negative pressure monitoring system, comprising a monitoring host 50 and at least one skin impedance acquisition device 60 provided in any of the above embodiments, wherein a skin impedance acquisition device 60 is provided in the canister of each cupping device 30;

the monitoring host 50 is configured to receive the skin impedance values from the skin impedance acquisition devices 60 respectively through wireless communication, determine suitability between the negative pressure in each cupping device 30 and the skin condition according to the received skin impedance values, and display the determined suitability between the negative pressure in each cupping device 30 and the skin condition.

In the embodiment of the present invention, the skin impedance collecting devices 60 are disposed in each cupping device 30, each skin impedance collecting device 60 can collect the impedance value of the skin in the cupping device 30, and each skin impedance collecting device 60 can send the collected skin impedance value to the monitoring host 50, so that the monitoring host 50 can determine whether the negative pressure in each cupping device 30 is suitable for the user according to the received skin impedance value, and determine whether the negative pressure in the cupping device 30 is suitable according to the skin impedance in the cupping device 30.

Optionally, based on the in-cupping device negative pressure monitoring system shown in fig. 7, the monitoring host 50 may also receive the pressure signal sent by each skin impedance acquisition device 60, so as to determine whether the negative pressure in each cupping device 30 is suitable for the user according to the pressure in each cupping device 30 and the impedance of the skin. The specific implementation mode is as follows:

The monitoring host 50 receives second pressure signals from each skin impedance acquisition device 60 in a wireless communication mode, wherein the second pressure signals are used for representing negative pressure values in the cupping device 30 where the corresponding skin impedance acquisition device 60 is located;

The monitoring host 50 calculates a first skin impedance threshold value and a second skin impedance threshold value from the skin impedance values and the second pressure signals acquired by the respective skin impedance acquisition devices 60 during a preset period of time after the negative pressure is generated from the inside of the cupping device 30, and performs the following processing for each skin impedance acquisition device 60 from the calculated first skin impedance threshold value and second skin impedance threshold value:

If the skin impedance value acquired by the skin impedance acquisition device 60 is greater than or equal to the first skin impedance threshold, safety is displayed for the skin impedance acquisition device 60;

If the skin impedance value acquired by the skin impedance acquisition device 60 is less than the first skin impedance threshold and greater than or equal to the second skin impedance threshold, displaying that the pressure is too great for the skin impedance acquisition device 60;

If the skin impedance value acquired by the skin impedance acquisition means 60 is smaller than the second skin impedance threshold value, it is displayed for the skin impedance acquisition means 60 that it should be stopped immediately.

In the embodiment of the present invention, after each of the cupping devices 30 is adsorbed to the skin of the user, each of the skin impedance acquiring devices 60 acquires the pressure and the skin impedance in the cupping device 30 where it is located in real time, and transmits the acquired pressure and skin impedance to the monitoring host 50. After the duration of generating the negative pressure in each cupping device 30 reaches the preset time period, the monitoring host 50 calculates a first skin impedance threshold value and a second skin impedance threshold value according to the second pressure signal and the skin impedance value acquired by each skin impedance acquisition device 60 in real time in the preset time period, and then the monitoring host 50 compares the skin impedance value acquired by each skin impedance acquisition device 60 with the first skin impedance threshold value and the second skin impedance threshold value, and determines whether the negative pressure in the corresponding cupping device 30 is suitable according to the real-time relationship between the skin impedance value and the first skin impedance threshold value and the second skin impedance threshold value.

In the embodiment of the present invention, the monitoring host 50 determines the first skin impedance threshold and the second skin impedance threshold according to the pressure signals and the skin impedance values acquired by the skin impedance acquisition devices 60, and further determines whether the negative pressure in the corresponding cupping device 30 is suitable according to the magnitude relation between the skin impedance values acquired in real time and the first skin impedance threshold and the second skin impedance threshold. Because the first skin impedance threshold and the second skin impedance threshold are determined according to the negative pressure in each cupping device 30 and the change of the skin impedance, the dynamic threshold is determined not for all users but for the tolerance of different individuals, and whether the negative pressure in the cupping device 30 is proper or not can be judged according to the tolerance of the skin of the user to the negative pressure, so that the cupping device 30 can be timely taken down from the skin of the user when the negative pressure in the cupping device 30 is large, and the safety of negative pressure cupping treatment is ensured.

In the embodiment of the present invention, for any one of the cupping devices 30, if the skin impedance value sent by the skin impedance collecting device 60 in the cupping device 30 is greater than or equal to the first skin impedance threshold value, it is indicated that the negative pressure of the cupping device 30 will not cause skin injury to the user, and accordingly, the display is "safe", if the skin impedance value sent by the skin impedance collecting device 60 in the cupping device 30 is less than the first skin impedance threshold value and greater than or equal to the second skin impedance threshold value, it is indicated that the negative pressure in the cupping device 30 is greater than the first skin impedance threshold value and causes skin injury to the user, and accordingly, the display is indicated as "over pressure" if the negative pressure in the cupping device 30 is too great and has caused serious injury to the skin of the user, and accordingly, the display is indicated as "should stop immediately".

In an embodiment of the present invention, the monitoring host 50 may specifically determine the first skin impedance threshold and the second skin impedance threshold, and determine the condition of the skin in the cupping device according to the first skin impedance threshold and the second skin impedance threshold:

S1, starting from the suction of the cupping device to the skin of a user, collecting a negative pressure value in the cupping device once in a preset first collecting period, and collecting an impedance value of the skin in the cupping device once in a preset second collecting period;

S2, 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 from small to large of the corresponding duration of the reference time period 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;

s3, calculating an average value of at least two impedance values acquired in a target reference period to serve as an initial impedance value;

s4, taking the product of the initial impedance threshold and a first preset coefficient as a first skin impedance threshold, and taking the product of the initial impedance threshold and a second preset coefficient as a second skin impedance threshold, wherein the first preset coefficient and the second preset coefficient are both larger than zero and smaller than 1, and the first preset coefficient is larger than the second preset coefficient;

s5, comparing each acquired impedance value after the first skin impedance threshold value and the second skin impedance threshold value are determined, if the impedance value is larger than or equal to the first skin impedance threshold value, determining that the skin in the cupping device is normal, if the impedance value is smaller than the first skin impedance threshold value and larger than or equal to the second skin impedance threshold value, determining that the skin in the cupping device is damaged, and if the impedance value is smaller than the second skin impedance threshold value, determining that the skin in the cupping device is seriously damaged.

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, and particularly, the impedance value of the skin is smaller as the damage degree of the skin is higher, 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.

The skin impedance threshold is determined according to an 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 order to reduce the probability of skin damage of the user due to the large negative pressure as much as possible, if the negative pressure in the cupping device is large when the negative pressure cupping treatment is started, the skin impedance threshold value should be determined in a short time so as to monitor the skin condition in the cupping device according to the skin impedance threshold value as soon as possible, and if the negative pressure in the cupping device is small 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 long 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.

After the target reference period is determined, an initial impedance value is calculated from the respective impedance values 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.

After the cupping device is adsorbed on the skin of a user, collecting a negative pressure value in the cupping device and an impedance value of the skin in the cupping device according to a preset period, determining a period of time from the adsorption of the cupping device on the skin of the user as a target reference period according to the negative pressure value in the cupping device, further determining a skin impedance threshold according to each acquired impedance value in the target reference period, and then comparing the newly acquired impedance value with the skin impedance threshold, and determining the skin condition in the cupping device according to the magnitude relation between the impedance value and the skin impedance threshold. 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.

Determining a first skin impedance threshold and a second skin impedance threshold according to the initial impedance threshold, wherein the first skin impedance threshold is a critical threshold for the occurrence of injury of the skin in the cupping device, the second skin impedance threshold is a critical threshold for the occurrence of serious injury of the skin in the cupping device, comparing the acquired impedance value with the first skin impedance threshold and the second skin impedance threshold can determine whether the skin in the cupping device is injured and the degree of the skin injury, and further displaying safety, overlarge pressure or immediate stop according to different monitoring results, so that the safety of negative pressure cupping treatment is ensured.

The first preset coefficient and the second preset coefficient are obtained by analyzing a large amount of data, for example, the first preset coefficient may be 0.6 and the second preset coefficient may be 0.4.

In the embodiment of the present invention, after determining the initial impedance value in S3, the method may further perform early warning of injury to the skin of the cupping device according to the initial impedance value, and may include the following steps:

S6, determining a corresponding target early warning reference period according to a reference negative pressure range corresponding to a target reference period, wherein the reference negative pressure ranges corresponding to different reference periods correspond to different early warning reference periods;

s7, judging inequality according to at least two negative pressure values acquired in the last target early warning reference period after each target early warning reference period passes Whether the negative pressure value is established or not, wherein n represents the number of the negative pressure values acquired in the last target early warning reference period, R _i represents the ith negative pressure value acquired in the last target early warning reference period, and R ₁ represents an initial impedance value;

s8 if inequality If so, sending out an early warning signal, wherein the early warning signal is used for indicating that the skin in the cupping device is at risk of injury.

The reference negative pressure range corresponding to each reference period corresponds to an early warning reference period, and the early warning reference periods corresponding to the reference negative pressure ranges corresponding to different reference periods are different, specifically, the larger the value in the reference negative pressure range is, the shorter the corresponding early warning reference period is. After determining the target reference period, determining a target early warning reference period corresponding to a reference negative pressure range corresponding to the target reference period, and judging inequality according to each acquired impedance value and initial impedance value in the target early warning reference period after each target early warning reference period passesWhether or not to hold, if notIf so, sending out an early warning signal to indicate that the skin in the cupping device is at risk of injury.

Because the greater the damage degree of the inner skin of the cupping device is, the smaller the inner skin impedance of the cupping device is, the average value of the inner skin impedance of the cupping device in a period of time is compared with the initial impedance value, whether the impedance value of the inner skin of the cupping device is continuously reduced can be determined, if the impedance value of the inner skin of the cupping device is continuously reduced and is reduced to a certain program, the risk of damage to the inner skin of the cupping device is indicated, and then an early warning signal is sent, the inner skin of the cupping device is timely treated in advance before the damage to the inner skin of the cupping device is caused, so that the inner skin damage of the cupping device is prevented, and the safety of negative pressure cupping treatment can be further improved.
