Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a skin impedance acquisition device and method, and a negative pressure monitoring system in a cupping device. Background Art

[0002] Cupping device is a device used for negative pressure cupping therapy. During negative pressure cupping therapy, negative pressure is formed inside the cupping device so that the cupping device is attached to the skin, which in turn causes congestion of subcutaneous tissue and superficial muscles, stimulating the skin, tendons, and meridian acupoints of the human body to eliminate toxins, dredge meridians, promote qi and blood circulation, strengthen the body, promote metabolism, and mobilize the functions of internal organs.

[0003] When using a cupping device for negative pressure cupping therapy, the skin may experience adverse symptoms such as capillary rupture, tissue fluid exudation, and tissue necrosis due to the large negative pressure. These adverse symptoms are related to the skin impedance inside the cupping device. Generally, the more severe the adverse reaction symptoms, the smaller the skin impedance inside the cupping device. Due to the different tolerances of different individuals, the condition of the skin inside the cupping device cannot be determined based on the negative pressure inside the cupping device. Therefore, the value of the skin impedance inside the cupping device can be used to judge whether the negative pressure inside the cupping device is safe and effective.

[0004] Since the cupping device is adsorbed on the skin, the existing skin impedance acquisition device cannot be inserted into the cupping device to detect the impedance of the skin inside the cupping device, and therefore it is impossible to determine whether the negative pressure inside the cupping device is safe and effective based on the skin impedance inside the cupping device.

[0054] As mentioned above, when performing negative pressure cupping therapy, negative pressure is formed in the cupping device and adsorbed on the user's skin. If the negative pressure in the cupping device is large, it may cause capillary rupture, tissue fluid exudation, skin bleeding, and tissue shedding in the skin of the cupping device. It is easy to cause adverse reactions such as tissue necrosis in the later stage, and even cause cross infection due to incomplete disinfection. Since different users have different tolerances to negative pressure, it is impossible to simply determine whether the negative pressure in the cupping device is safe and effective based on the size of the negative pressure in the cupping device. The adverse reactions of the skin in the cupping device are correlated with the impedance of the skin in the cupping device. Specifically, the more severe the adverse reactions of the skin, the smaller the skin impedance. Therefore, it is possible to determine whether the negative pressure in the cupping device is safe and effective by detecting the impedance of the skin in the cupping device. However, since the cupping device is adsorbed on the user's skin, the existing skin impedance acquisition device cannot be inserted into the cupping device to detect the impedance of the skin. Therefore, it is impossible to determine whether the negative pressure in the cupping device is suitable for the corresponding user based on the impedance of the skin in the cupping device, that is, it is impossible to determine whether the negative pressure in the cupping device is safe and effective based on the impedance of the skin in the cupping device.

[0055] In the embodiment of the present invention, the impedance acquisition sheet is composed of a substrate and a conductive electrode arranged on the substrate. The substrate surface is adhered to the inner wall of the cupping tube by adhesive, and the first end of the substrate is flush with the cupping mouth of the cupping device, while the second end of the substrate is connected to the acquisition component, the acquisition component is fixed in the cupping device and the conductive electrode on the substrate is connected to the impedance detection circuit in the acquisition component. When the cupping device is adsorbed on the user's skin, the user's skin contacts the conductive electrode on the first end of the substrate, so that the impedance detection circuit and the user's skin form a loop, so that 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 the external monitoring host by wireless communication through the Tonggu wireless communication module, so that the monitoring host can determine whether the negative pressure in the cupping device is suitable for the user according to the skin impedance value, thereby realizing the judgment of whether the negative pressure in the cupping device is safe and effective according to the impedance of the skin in the cupping device.

[0056] The skin impedance acquisition device, method and cupping device internal negative pressure monitoring system provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a skin impedance acquisition device, comprising: an impedance acquisition sheet 10 and an acquisition component 20;

[0058] The acquisition component 20 includes: an impedance detection circuit 21, a processor 22 and a wireless communication module 23, wherein the processor 22 is connected to the impedance detection circuit 21 and the wireless communication module 23 respectively;

[0059] The impedance collection sheet 10 includes: 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, 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;

[0060] The back side of the substrate 11 is adhered to the inner wall of the cupping device 30 by adhesive, the first end of the substrate 11 is flush with the cupping mouth of the cupping device 30, and the second end of the substrate 11 is connected to the collection component 20 to fix the collection component 20 in the cupping device 30, and each conductive electrode 12 is connected to the impedance detection circuit 21;

[0061] When the cupping device 30 is attached to the user's skin 40, the user's skin 40 contacts the conductive electrodes 12 at the first end of the substrate 11, so that the user's skin 40 and the impedance detection circuit 21 form a loop, and 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;

[0062] 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 via the wireless communication module 23 in a wireless communication manner, 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.

[0063] In the embodiment of the present invention, the front side of the substrate 11 is provided with a conductive electrode 12, and the back side of the substrate 11 can be adhered to the inner wall of the cupping device 30 by adhesive, the first end of the substrate 11 is flush with the cupping mouth of the cupping device 30, and the second end of the substrate 11 is connected to the collection component 20, so that the impedance collection sheet 10 and the collection component 20 can be fixed in the cupping device 30, and the conductive electrode 12 is connected to 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 will enter the cupping device 30 and contact each conductive electrode 12 on the first end of the substrate 11, so that the skin 40 of the user forms a loop with the impedance detection circuit 21, and then 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 by wireless communication 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 collection component 20 can collect the skin impedance value of the skin 40 in the cupping device 30 through the impedance collection sheet 10, and send 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 based on the received skin impedance value, thereby being able to determine whether the negative pressure in the cupping device 30 is safe and effective based on the impedance of the skin in the cupping device 30.

[0064] Optionally, in Figure 2 Based on the skin impedance acquisition device shown in Figure 3 As shown, the acquisition component 20 further includes: a pressure sensor 24 and a pressure signal processor 25;

[0065] The pressure sensor 24 is connected to the pressure signal processor 25, and the pressure signal processor 25 is connected to the processor 22;

[0066] When the cupping device 30 is attached to the user's skin 40, the pressure sensor 24 can detect the pressure inside the cupping device 30, obtain a first pressure signal according to the detected pressure, and send the obtained first pressure signal to the pressure signal processor 25;

[0067] The pressure signal processor 25 can amplify and compensate the first pressure signal to obtain a second pressure signal, and send the obtained second pressure signal to the processor 22;

[0068] The processor 22 can send the second pressure signal to the monitoring host 50 by wireless communication through the wireless communication module 23, so that the monitoring host 50 can display the pressure in the cupping device 30 according to the second pressure signal, and determine 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.

[0069] In the embodiment of the present invention, the pressure sensor 24 can collect the pressure in the cupping device 30. The collected pressure will be sent to the monitoring host 50 after signal processing, and then the monitoring host 50 can display the pressure in the cupping device 30, so that the user can easily determine the pressure in the cupping device 30. In addition, the monitoring host 50 can also combine the pressure in the cupping device 30 and the impedance of the skin in the cupping device 30 to determine whether the negative pressure in the cupping device 30 is appropriate, thereby ensuring that it can more accurately judge whether the negative pressure in the cupping device 30 is suitable for the user's skin.

[0070] The pressure sensor 24 can be an absolute negative pressure type pressure sensor, and the maximum nominal value of the negative pressure is 50-100 kPa. Since the pressure sensor 24 is placed in the cupping device 30 where negative pressure exists, what needs to be detected is the pressure difference between the inside of the cupping device 30 and the outside of one atmosphere. Therefore, a sensor with one atmosphere of pressure inside (absolute pressure sensor) is selected as the pressure sensor 24.

[0071] 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 can amplify and compensate the first pressure signal. The amplification process mainly amplifies the first pressure signal so that the obtained second pressure signal can more clearly reflect the magnitude of the pressure in the cupping device 30; the compensation process mainly includes precision compensation and temperature compensation for the first pressure signal. Since the pressure is affected by factors such as temperature, the precision compensation and temperature compensation for the first pressure signal can make the obtained second pressure signal more accurately reflect the magnitude of the pressure in the cupping device 30.

[0072] The pressure signal processor 25 obtains a second pressure signal after amplifying and compensating the first pressure signal, so that the second pressure signal can more clearly and accurately reflect the pressure in the cupping device 30, thereby enabling the monitoring host 50 to accurately display the pressure in the cupping device 30 and improve the accuracy of judging whether the negative pressure in the cupping device 30 is suitable for the user.

[0073] Optionally, in Figure 1 and Figure 2On the basis of the skin impedance acquisition device shown, the acquisition component 20 further includes a shell made of high temperature resistant polymer material, and other components included in the acquisition component 20, such as the impedance detection circuit 21, the processor 22 and the wireless communication module 23, are all located in the shell.

[0074] In the embodiment of the present invention, since the collection component 20 is fixed in the cupping device 30 when in use, and the thermotype cupping device that relies on consuming oxygen in the cup body to achieve adsorption will have a short high temperature during use, the collection component 20 will be in short contact with the high temperature. In order to prevent the collection component 20 from being damaged due to short contact with high temperature, the impedance detection circuit 21, processor 22, wireless communication module 23 and other components included in the collection component 20 are arranged in a shell made of high temperature resistant polymer material. When the collection component 20 is in short contact with high temperature, the shell made of high temperature resistant polymer material can be insulated to protect the various components arranged therein, ensuring that the collection component 20 will not be damaged due to short contact with high temperature.

[0075] In addition, the shell of the collection component 20 is made of high temperature resistant polymer material, which ensures that the collection component 20 will not be damaged due to short-term contact with high temperature. On the other hand, since the polymer material has a small density, the collection component 20 can be ensured to have a small weight, thereby facilitating the collection component 20 to be fixed in the cupping device 30.

[0076] Optionally, in Figure 1 and Figure 2 Based on the skin impedance acquisition device shown, the material of the substrate 11 can be polyphenylene sulfide (PPS) or cardboard.

[0077] In the embodiment of the present invention, for a thermal prototype cupping device that relies on consuming oxygen in the cup body to achieve adsorption, such cupping devices will have a short-term high temperature during use. Using polyphenylene sulfide to make the substrate 11 of the impedance acquisition sheet 10 can prevent the impedance acquisition sheet 10 from being damaged due to short-term contact with high temperature. For a non-thermal prototype cupping device, such cupping devices will not have a high temperature during use, so the substrate 11 of the impedance acquisition sheet 10 can be made of cardboard to ensure that the impedance acquisition sheet 10 has a low production cost.

[0078] Optionally, in Figure 1 and Figure 2 Based on the skin impedance acquisition device shown in Figure 4 As shown, the substrate 11 includes a first backing plate 111 and a second backing plate 112;

[0079] The first lining plate 111 and the second lining plate 112 are both rectangular sheet structures;

[0080] The first lining plate 111 and the second lining plate 112 are connected to form an L-shaped structure, and the second lining plate 112 can be folded along the connection line between the first lining plate 111 and the second lining plate 112 to make the plane where the first lining plate 111 is located perpendicular to the plane where the second lining plate 112 is located;

[0081] When the back surface of the first lining plate 111 is adhered to the inner wall of the cupping device 30 by adhesive, the second lining plate 112 whose plane is perpendicular to the plane of the first lining plate 111 is connected to the collecting component 20 .

[0082] In the embodiment of the present invention, the substrate 11 is composed of a first lining plate 111 and a second lining plate 112 connected to each other. The first lining plate 111 and the second lining plate 112 can be relatively flattened or folded. When the first lining plate 111 and the second lining plate 112 are in a flattened state, Figure 4 As shown in the left figure, the first lining plate 111 and the second lining plate 112 are in the folded state. Figure 4 When the first lining plate 111 and the second lining plate 112 are in the folded state, the first lining plate 111 can be adhered to the inner wall of the cupping device 30 by adhesive, and the plane where the second lining plate 112 is located is perpendicular to the plane where the first lining plate 111 is located, so that the collection component 20 can be easily connected to the second lining plate 112.

[0083] The substrate 11 adopts a foldable structure. When the impedance acquisition sheet 10 is not in use, the first lining plate 111 and the second lining plate 112 are in a flat state, which is convenient for the storage of the impedance acquisition sheet 10. When the impedance acquisition sheet 10 is in use, the first lining plate 111 and the second lining plate 112 can be folded to a folded state, which is convenient for connecting the acquisition component 20 with the impedance acquisition sheet 10.

[0084] It should be noted that the end of the first backing plate 111 away from the second backing plate 112 is the first end of the substrate 11 , and the end of the second backing plate 112 away from the first backing plate 111 is the second end of the substrate 11 .

[0085] In the embodiment of the present invention, Figure 4 As shown, two parallel conductive electrodes 12 are arranged on the front side of the substrate 11, and the two conductive electrodes 12 penetrate the first backing plate 111 and the second backing plate 112, so that the user's skin 40 and the impedance detection resistor 21 can form a loop through the two conductive electrodes 12. The conductive electrodes 12 can be conductive silver paste electrodes made by a printing process, that is, silver paste is brushed on the substrate 11 by a printing process to form electrodes.

[0086] In the embodiment of the present invention, it is defined that the length side of the first lining plate 111 is connected to the width side of the second lining plate 112, then the length of the first lining plate 111 is in the range of 20-50 mm, the width of the first lining plate 111 is in the range of 3-12 mm, the length of the second lining plate 112 is in the range of 10-20 mm, the width of the second lining plate 112 is in the range of 5-10 mm, and the thickness of the first lining plate 111 and the second lining plate 112 is in the range of 1-3 mm.

[0087] It should be noted that since the impedance collection sheet 10 is adhered to the inner wall of the cupping device 30 by adhesive, the adhesive is difficult to remove after use. In addition, in order to avoid cross infection caused by different users using the same impedance collection sheet 10, the impedance collection sheet 10 is designed as a disposable product.

[0088] Optionally, in Figure 4 As shown in the impedance acquisition sheet 10, Figure 5 As shown, the collection component 20 further includes: an electrode connector 26;

[0089] The electrode connector 26 is provided with two connector springs 261, and the two connector springs 261 are connected to two terminals of the impedance detection circuit 21, wherein each connector spring 261 is connected to one terminal of the impedance detection circuit 21;

[0090] When the second lining plate 112 is inserted into the electrode connector 26 , the two connector springs 261 clamp and fix the second lining plate 112 , and the two conductive electrodes 12 arranged on the front side of the second lining plate 112 contact the two connector springs 261 , wherein different conductive electrodes 12 contact different connector springs 261 .

[0091] In the embodiment of the present invention, the collection component 20 is provided with an electrode connector 26, and the electrode connector 26 includes two connector springs 261. When the second lining plate 112 is inserted into the electrode connector 26, the two connector springs 261 are elastically deformed to clamp and fix the second lining plate 112, and the first lining plate 111 connected to the second lining plate 112 is adhered to the inner wall of the cupping device 30, thereby achieving the collection component 20 being fixed in the cupping device 30. In addition, the two connector springs 261 included in the electrode connector 26 are respectively connected to the two terminals of the impedance detection circuit 21. When the second lining plate 112 is inserted into the electrode connector 26, the two conductive electrodes 12 provided on the front of the second lining plate 112 are respectively in contact with the two connector springs 261, so that the impedance detection circuit 21 and the user's skin 40 form a loop, so that the impedance detection circuit 21 can detect the impedance of the skin in the cupping device 30.

[0092] In the embodiment of the present invention, an electrode connector 26 is provided on the collection component 20, and two connector springs 261 are provided on the electrode connector 26.

[0093] Optionally, in Figure 3 Based on the skin impedance acquisition device shown in Figure 6 As shown, the acquisition component 20 further includes: a rechargeable battery 27, a battery management module 28, a charging module 29, a power conversion module 210 and a detection circuit power supply module 211;

[0094] The charging module 29 is connected to the battery management module 28, the battery management module 28 is connected to the rechargeable battery 27, and the rechargeable battery 27 is connected to the power conversion module 210;

[0096] The current output end of the detection circuit power supply module 211 is connected to one end of the sampling resistor R, the other end of the sampling resistor R is connected to a connector spring 261 on the electrode connector 26, and the current input end of the detection circuit power supply module 211 is connected to another connector spring 261 on the electrode connector 26;

[0097] Two terminals of the impedance detection circuit 21 are connected to two ends of the sampling resistor R respectively.

[0098] In the embodiment of the present invention, the battery management module 28 is used to monitor the power of the rechargeable battery 27 in real time, and control the charging module 29 to charge the rechargeable battery 27. The charging module 29 can charge the rechargeable battery 27 by inductive charging or contact charging, wherein the inductive charging is to charge the rechargeable battery 27 by receiving the power from the monitoring host 50 through the induction coil, and the contact charging is to charge the rechargeable battery 27 by receiving the power from the monitoring host 50 through the charging connection line.

[0099] In an embodiment of the present invention, the power conversion module 210 is used to perform corresponding DC / DC conversion on the voltage output by the rechargeable battery 27 to provide it to components such as the detection circuit power supply module 211, the processor 22, the pressure sensor 24 and the pressure signal processor 25 for use.

[0100] In the embodiment of the present invention, since the user's skin 40 is connected in parallel with the sampling resistor R, the impedance detection circuit 21 detects the voltage or current across the sampling resistor R, and then determines the impedance of the user's skin 40 based on the detected voltage or current combined with the resistance value of the sampling resistor R.

[0101] In the embodiment of the present invention, the detection circuit power supply module 211 is used to deliver direct current or alternating current to the impedance detection circuit 21. The impedance detection circuit 21 forms a conductive loop with the user's skin through the conductive electrode 12 on the impedance acquisition sheet 10, and detects the impedance value of the user's skin in the cupping device 30 in real time. The detection circuit power supply module 211 can deliver direct current or alternating current to the impedance detection circuit 21 in a constant voltage or constant current manner, wherein the current value range of the detection circuit power supply module 211 in a constant current manner is 50μA-10mA, and the voltage value range of the detection circuit power supply module 211 in a constant voltage manner is 1-12V. If alternating current is delivered, the frequency range of the alternating current is 5-100Hz.

[0102] In the embodiment of the present invention, the wireless communication module 23 is used to send the pressure signal obtained by the pressure sensor 24 and the pressure signal processor 25, the skin impedance value obtained by the skin impedance detection circuit 21, and the power information obtained by the battery management module 28 to the monitoring host 50 by wireless communication, so that the monitoring host 50 can display the pressure in the cupping device 30, the power of the rechargeable battery 27, and the suitability of the negative pressure in the cupping device 30 with the user's skin. In addition, when the user performs negative pressure cupping therapy, it is usually necessary to simultaneously adsorb multiple cupping devices 30 on the skin, and each cupping device 30 is provided with a skin impedance acquisition device, and each skin impedance acquisition device needs to send information to the monitoring host 50. In order to enable the monitoring host 50 to distinguish the information sent by different skin impedance acquisition devices, the wireless communication module 23 can adjust the address code, so that different skin impedance acquisition devices include wireless communication modules 23 with different addresses, so that the monitoring host 50 can determine which skin impedance detection device sent the information according to the address code included in the received information.

[0103] In addition, the wireless communication module 23 can communicate with the monitoring function host 50 via wireless communication methods such as Bluetooth and WiFi.

[0104] In the embodiment of the present invention, the processor 22 is used to coordinate and process other modules in the acquisition component 20 as a whole.

[0105] like Figure 7As shown, an embodiment of the present invention provides a negative pressure monitoring system in a cupping device, 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 cup body of each cupping device 30;

[0106] The monitoring host 50 is used to receive the skin impedance values ​​from each skin impedance acquisition device 60 respectively through wireless communication, and determine the 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.

[0107] In the embodiment of the present invention, a skin impedance acquisition device 60 is provided in each cupping device 30, and each skin impedance acquisition device 60 can respectively collect the impedance value of the skin in the cupping device 30, and each skin impedance acquisition device 60 can send the collected skin impedance value to the monitoring host 50, and then 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 values, thereby determining whether the negative pressure in the cupping device 30 is appropriate according to the impedance of the skin in the cupping device 30.

[0108] Optionally, in Figure 7 Based on the negative pressure monitoring system in the cupping device shown, the monitoring host 50 can also receive the pressure signal sent by each skin impedance acquisition device 60, and then 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 skin impedance. The specific implementation method is:

[0109] The monitoring host 50 receives the second pressure signal from each skin impedance acquisition device 60 by wireless communication, wherein the second pressure signal is used to represent the negative pressure value in the cupping device 30 where the corresponding skin impedance acquisition device 60 is located;

[0110] The monitoring host 50 calculates the first skin impedance threshold and the second skin impedance threshold according to the skin impedance values ​​and the second pressure signals collected by each skin impedance collection device 60 within a preset time period after the negative pressure is generated in the cupping device 30, and performs the following processing for each skin impedance collection device 60 according to the calculated first skin impedance threshold and second skin impedance threshold:

[0111] If the skin impedance value collected by the skin impedance collection device 60 is greater than or equal to the first skin impedance threshold, the skin impedance collection device 60 is displayed as safe;

[0112] If the skin impedance value collected by the skin impedance collection device 60 is less than the first skin impedance threshold and greater than or equal to the second skin impedance threshold, the skin impedance collection device 60 displays that the pressure is too high;

[0113] If the skin impedance value collected by the skin impedance collection device 60 is less than the second skin impedance threshold, the display of the skin impedance collection device 60 should be stopped immediately.

[0114] In the embodiment of the present invention, after each cupping device 30 is adsorbed onto the user's skin, each skin impedance acquisition device 60 respectively acquires the pressure and skin impedance in the cupping device 30 in which it is located in real time, and sends the acquired pressure and skin impedance to the monitoring host 50. When the duration of negative pressure generated in each cupping device 30 reaches a preset time period, the monitoring host 50 calculates the first skin impedance threshold and the second skin impedance threshold according to the second pressure signal and skin impedance value acquired in real time by each skin impedance acquisition device 60 within the preset time period, and then the monitoring host 50 compares the skin impedance value acquired by each skin impedance acquisition device 60 thereafter with the first skin impedance threshold and the second skin impedance threshold, and determines whether the negative pressure in the corresponding cupping device 30 is appropriate according to the relationship between the real-time skin impedance value and the first skin impedance threshold and the second skin impedance threshold.

[0115] 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 signal and the skin impedance value acquired by each skin impedance acquisition device 60, and then determines whether the negative pressure in the corresponding cupping device 30 is appropriate according to the magnitude relationship between the skin impedance value acquired in real time and the first skin impedance threshold and the second skin impedance threshold. Since the first skin impedance threshold and the second skin impedance threshold are determined according to the changes in the negative pressure and skin impedance in each cupping device 30, they are not uniform fixed values ​​for all users, but dynamic thresholds determined according to the tolerance of different individuals, and then it can be judged whether the negative pressure in the cupping device 30 is appropriate according to the tolerance of the user's skin to negative pressure, so that when the negative pressure in the cupping device 30 is large, the cupping device 30 can be removed from the user's skin in time to ensure the safety of negative pressure cupping therapy.

[0116] In the embodiment of the present invention, for any cupping device 30, if the skin impedance value sent by the skin impedance acquisition device 60 in the cupping device 30 is greater than or equal to the first skin impedance threshold, it means that the negative pressure of the cupping device 30 will not cause skin damage to the user, and "safe" is displayed accordingly; if the skin impedance value sent by the skin impedance acquisition device 60 in the cupping device 30 is less than the first skin impedance threshold and greater than or equal to the second skin impedance threshold, it means that the negative pressure in the cupping device 30 is relatively large and causes skin damage to the user, and "pressure is too high" is displayed accordingly; if the skin impedance value sent by the skin impedance acquisition device 60 in the cupping device 30 is less than the second skin impedance threshold, it means that the negative pressure in the cupping device 30 is too large and has caused serious damage to the user's skin, and "stop immediately" is displayed accordingly.

[0117] In the embodiment of the present invention, the monitoring host 50 can specifically determine the first skin impedance threshold and the second skin impedance threshold in the following manner, and determine the condition of the skin in the cupping device according to the first skin impedance threshold and the second skin impedance threshold:

[0118] S1: starting from when the cupping device is attached to the user's skin, the negative pressure value in the cupping device is collected once every preset first collection period, and the impedance value of the skin in the cupping device is collected once every preset second collection period;

[0119] S2: for at least two preset reference time periods, the average values ​​of at least two negative pressure values ​​collected in each reference time period are calculated in order from small to large according to the corresponding time lengths of the reference time periods, until it is determined that the average value of at least two negative pressure values ​​collected in a reference time period is within the reference negative pressure range corresponding to the reference time period, and the reference time period is determined as the target reference time period, wherein the starting point of the reference time period is the time when the cupping device is adsorbed on the user's skin, and different reference time periods correspond to different reference negative pressure ranges;

[0120] S3: Calculate the average of at least two impedance values ​​collected during the target reference period as the initial impedance value;

[0121] S4: taking the product of the initial impedance threshold and the first preset coefficient as the first skin impedance threshold, and taking the product of the initial impedance threshold and the second preset coefficient as the second skin impedance threshold, wherein both the first preset coefficient and the second preset coefficient are greater than zero and less than 1, and the first preset coefficient is greater than the second preset coefficient;

[0122] S5: For each impedance value collected after determining the first skin impedance threshold and the second skin impedance threshold, compare the impedance value with the first skin impedance threshold and the second skin impedance threshold; if the impedance value is greater than or equal to the first skin impedance threshold, determine that the skin in the cupping device is normal; if the impedance value is less than the first skin impedance threshold and greater than or equal to the second skin impedance threshold, determine that the skin in the cupping device is damaged; if the impedance value is less than the second skin impedance threshold, determine that the skin in the cupping device is severely damaged.

[0123] During negative pressure cupping therapy, the impedance value of the skin inside the cupping device is related to the degree of damage to the skin inside the cupping device. Specifically, the higher the degree of skin damage, the smaller the skin impedance value. Therefore, the condition of the skin inside the cupping device can be judged based on the impedance value of the skin inside the cupping device. However, due to the different tolerance of different individuals, it is necessary to determine the corresponding skin impedance threshold for each user who undergoes negative pressure cupping therapy, so as to determine whether the skin inside the cupping device is damaged and the degree of damage based on the skin impedance threshold and the impedance value of the skin inside the cupping device.

[0124] The skin impedance threshold needs to be determined based on the initial impedance value of the skin in the cupping device at the initial stage of negative pressure cupping therapy, that is, when the user's skin is not damaged at the beginning of negative pressure cupping therapy, the skin impedance value in the cupping device is in the normal range. Since the skin impedance value in the cupping device measured at a single time may fluctuate, in order to ensure that the skin impedance threshold determined based on the initial impedance value has a high accuracy, the average value of the skin impedance value in the cupping device within a period of time after the negative pressure cupping therapy begins can be used as the initial impedance value.

[0125] The greater the negative pressure in the cupping device, the greater the probability of causing skin damage in the cupping device. In order to minimize the probability of user skin damage due to large negative pressure, if the negative pressure in the cupping device is large when negative pressure cupping therapy begins, the skin impedance threshold should be determined in a relatively short time so that the skin condition in the cupping device can be monitored as soon as possible based on the skin impedance threshold. If the negative pressure in the cupping device is small when negative pressure cupping therapy begins, the time required to determine the skin impedance threshold can be appropriately extended, that is, the skin impedance threshold is determined based on the skin impedance values ​​collected over a long period of time at the beginning of negative pressure cupping therapy to ensure the accuracy of the determined skin impedance threshold.

[0126] In order to determine the duration of collecting impedance values ​​required to calculate the skin impedance threshold value according to the negative pressure in the cupping device, multiple reference time periods are pre-set, each of which has a different duration, and each reference time period starts timing when the cupping device is adsorbed on the user's skin, and different reference time periods correspond to different reference negative pressure ranges. When the timing length of a reference time period reaches the duration of the reference time period, the average value of each negative pressure value collected in the reference time period is calculated. If the calculated average value is within the reference negative pressure range corresponding to the reference time period, the reference time period is determined as the target reference time period, and then the skin impedance threshold is calculated according to the impedance value collected in the target reference time period. After that, other reference time periods are no longer timed. If the calculated average value is not within the reference negative pressure range corresponding to the reference time period, the subsequent reference time periods continue to time until the timing length of the next reference time period reaches the corresponding duration, and the next reference time period is processed in the same manner as above until the target reference time period is determined.

[0127] After determining the target reference period, the initial impedance value is calculated based on the impedance values ​​collected during the target reference period, and then one or more skin impedance thresholds are determined based on the calculated initial impedance value. After obtaining the skin impedance threshold, each time an impedance value is collected, the collected impedance value is compared with each skin impedance threshold, and then the condition of the skin in the cupping device is determined based on the magnitude relationship between the impedance value and each skin impedance threshold.

[0128] After the cupping device is attached to the user's skin, 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 cycle, and a period of time from the time the cupping device is attached to the user's skin is determined as a target reference period based on the negative pressure value in the cupping device, and then the skin impedance threshold is determined based on each impedance value collected during the target reference period, and then the newly collected impedance value can be compared with the skin impedance threshold, and the condition of the skin in the cupping device can be determined based on the relationship between the impedance value and the skin impedance threshold. On the one hand, since there is a specific relationship between the impedance value of the skin and the degree of skin damage, and on the other hand, since the skin impedance threshold is determined based on the impedance value of the skin in the cupping device in the initial stage of negative pressure cupping therapy, the condition of the skin in the cupping device can be determined based on the skin impedance threshold determined for the individual user and the impedance value of the skin in the cupping device, so that the condition of the skin in the cupping device can be monitored more accurately.

[0129] The first skin impedance threshold and the second skin impedance threshold are determined according to the initial impedance threshold, wherein the first skin impedance threshold is the critical threshold at which the skin in the cupping device begins to be damaged, and the second skin impedance threshold is the critical threshold at which the skin in the cupping device is seriously damaged. By comparing the collected impedance value with the first skin impedance threshold and the second skin impedance threshold, it can be determined whether the skin in the cupping device is damaged and the extent of the skin damage, and then according to different monitoring results, "safe", "excessive pressure" or "should stop immediately" can be displayed to ensure the safety of negative pressure cupping therapy.

[0130] 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.

[0131] In the embodiment of the present invention, after the initial impedance value is determined in S3, a warning of damage to the skin inside the cupping device can be issued according to the initial impedance value, which can include the following steps:

[0132] S6: Determine a corresponding target warning reference period according to the reference negative pressure range corresponding to the target reference period, wherein reference negative pressure ranges corresponding to different reference periods correspond to different warning reference periods;

[0133] S7: After each target warning reference cycle, based on at least two negative pressure values ​​collected in the most recent target warning reference cycle, determine the inequality Is it true, where n represents the number of negative pressure values ​​collected in the most recent target warning reference period, R i represents the i-th negative pressure value collected in the most recent target warning reference period, and R1 represents the initial impedance value;

[0134] S8: Inequality If it is established, a warning signal is issued, wherein the warning signal is used to indicate that there is a risk of injury to the skin inside the cupping device.

[0135] The reference negative pressure range corresponding to each reference time period corresponds to a warning reference cycle, and the reference negative pressure ranges corresponding to different reference time periods have different warning reference cycles. Specifically, the larger the value in the reference negative pressure range, the shorter the corresponding warning reference cycle. After determining the target reference time period, determine the target warning reference cycle corresponding to the reference negative pressure range corresponding to the target reference time period. After each target warning reference cycle, the inequality is determined based on the impedance values ​​and initial impedance values ​​collected within the target warning reference cycle. Is it true that if the inequality If established, a warning signal is issued to indicate that there is a risk of injury to the skin inside the cupping device.

[0136] Since the greater the degree of damage to the skin in the cupping device, the smaller the impedance of the skin in the cupping device, by comparing the average value of the impedance of the skin in the cupping device over a period of time with the initial impedance value, it can be determined whether the impedance value of the skin in the cupping device is continuously decreasing. If it is determined that the impedance value of the skin in the cupping device is continuously decreasing and decreases to a certain level, it means that there is a risk of damage to the skin in the cupping device, and then a warning signal is issued. Preliminary treatment can be performed in time before the skin in the cupping device is damaged to prevent damage to the skin in the cupping device, which can further improve the safety of negative pressure cupping therapy.

[0137] like Figure 8 As shown, one embodiment of the present invention provides a skin impedance acquisition method based on the skin impedance acquisition device provided by any of the above embodiments, and the method may include the following steps:

[0138] Step 801: Adhere the back side of the substrate to the inner wall of the cupping device by means of adhesive, so that the first end of the substrate is flush with the cupping device;

[0139] Step 802: Connecting the collecting component to the second end of the substrate to fix the collecting component in the cupping device, and connecting at least two conductive electrodes to the impedance detection circuit;

[0140] Step 803: attaching the cupping device to the user's skin so that the user's skin contacts at least two conductive electrodes at the first end of the substrate;

[0141] Step 804: using the impedance detection circuit to detect the skin impedance value of the user, and sending the detected skin impedance value to the processor;

[0142] Step 805: Using the processor, the skin impedance value is sent to an external monitoring host via the wireless communication module in a wireless communication manner, so that the monitoring host determines the suitability between the negative pressure in the cupping device and the skin condition according to the skin impedance value.

[0143] In an embodiment of the present invention, after the impedance acquisition sheet and the acquisition component are fixed to the inside of the cupping device, the cupping device is adsorbed on the user's skin. Thereafter, the acquisition component may acquire the impedance of the skin in the cupping device through the impedance acquisition sheet, and send the acquired skin impedance value to the monitoring host through wireless communication. The monitoring host may then determine the suitability between the negative pressure in the cupping device and the user's skin condition based on the received skin impedance value, thereby being able to determine whether the negative pressure in the cupping device is appropriate based on the impedance of the skin in the cupping device.

[0146] Amplifying and compensating the first pressure signal using a pressure signal processor to obtain a second pressure signal;

[0147] The processor sends the second pressure signal to the monitoring host through the wireless communication module by wireless communication, so that the monitoring host can display the pressure in the cupping device according to the second pressure signal, and determine the suitability between the negative pressure in the cupping device and the skin condition according to the skin impedance value and the second pressure signal.

[0148] In the embodiment of the present invention, after the cupping device is attached to the user's skin, the collecting component can also collect the pressure signal in the cupping device, and send the collected pressure signal to the monitoring host after processing, so that the monitoring host can display the pressure in the cupping device, so that the doctor can view the pressure in the cupping device in real time, so that the doctor can accumulate the experience of negative pressure cupping treatment. In addition, the monitoring host can judge whether the negative pressure in the cupping device is appropriate by combining the strong pressure in the cupping device and the impedance value of the skin in the cupping device, thereby ensuring the accuracy of determining whether the negative pressure in the cupping device is appropriate according to the skin impedance in the cupping device.
