Description

Technical Field

[0001] The present invention relates to a cupping main unit, in particular to a multifunctional visual intelligent multi-head cupping main unit, belonging to the technical field of innovative traditional Chinese medicine equipment. Background Art

[0002] Cupping is a Traditional Chinese Medicine (TCM) therapeutic procedure that uses a cupping device to create negative pressure on the skin through combustion, suction, steam, and other methods. This prolonged application can cause localized congestion or congestion of blood, providing a beneficial stimulation that can help treat illness. It's commonly used clinically to treat colds, coughs, asthma, lumbar disc herniation, cervical spondylosis, frozen shoulder, soft tissue injuries, stomachache, abdominal pain, vomiting, dysmenorrhea, and stroke.

[0003] The three most common types of cupping are fire cupping, medicine cupping, and water cupping. Based on the material, they are further categorized into bamboo cupping, ceramic cupping, glass cupping, plastic vacuum cupping, metal cupping, magnetic negative pressure cupping, and rubber cupping. Based on the operating technique, they are further categorized into single cupping, multiple cupping, moving cupping, flash cupping, blood-letting cupping, and needle cupping.

[0004] Currently, most common vacuum tanks use piston-type pumping, with multiple independent tanks. The negative pressure generated by the pumping volume is measured by the piston's travel, requiring a certain amount of manual labor. When the tanks are combined with fire cupping or medicine cupping, the pressure and temperature inside the tank cannot be manually monitored. Furthermore, individual physical conditions vary, and this can occasionally cause localized skin damage to some people.

DETAILED DESCRIPTION

[0044] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] A multi-cup holder main unit is provided, with a chassis 1 as a main body.

[0046] Preferably, a column and a base are provided at the bottom of the chassis 1, and rollers may be provided at the bottom of the base to facilitate the movement of the chassis 1 and provide convenience for use.

[0047] The chassis 1 is provided with a negative pressure chamber 13 and a vacuum pump 15. A pressure sensor 14 is located within the negative pressure chamber 13. One side of the negative pressure chamber 13 is connected to the vacuum pump 15, and the other side is connected to a plurality of negative pressure tubes 4. Each negative pressure tube 4 is equipped with a solenoid three-way valve 12. The negative pressure tubes 4 terminate at a tank connector 3, which is used to connect to the tank body 11.

[0048] The vacuum pump 15 , the pressure sensor 14 and the electromagnetic three-way valve 12 are all connected to the control device.

[0049] like Figure 1 and 2 As shown, the electromagnetic three-way valve 12 has a B port, an A port and an X port, wherein the B port is connected to the negative pressure chamber 13, the A port is connected to the fire cup, and the X port is connected to the pressure relief port. When the electromagnetic three-way valve 12 is energized, the state is as follows Figure 1 As shown, BA is a passage, X port is blocked, and the negative pressure chamber 13 continuously provides negative pressure to the tank body 11 through the negative pressure pipe 4; when the electromagnetic three-way valve 12 is powered off, the state is as follows Figure 2 As shown, under the elastic force of the end spring, the piston is displaced, XA becomes a passage, port B is blocked, and the negative pressure chamber 13 no longer provides negative pressure for the tank body 11; at the same time, the negative pressure in the tank body 11 is released through port X, and the tank body 11 can be separated from the skin.

[0050] During use, the pressure in the negative pressure chamber 13 can be preset to P0, and a certain amplitude range ΔP can be set. When multiple tank bodies 11 are connected or after a period of use, P0 changes and increases to >P0+ΔP. The control device starts the vacuum pump 15 based on the feedback from the pressure sensor 14 to adjust the real-time pressure P in the negative pressure chamber 13 back to the range of P0±ΔP. Preferably, when P<P0-ΔP, the vacuum pump 15 is turned off. Through the negative pressure chamber 13, multiple tank bodies 11 can share the same negative pressure source. Only one vacuum pump 15 is required, and there is no need to frequently start and close it to provide negative pressure for a single tank body 11. And it can provide stable and uniform negative pressure for multiple tank bodies 11.

[0051] Preferably, P0=-0.03 MPa, ΔP=0.02 MPa, that is, the range of P0±ΔP is (-0.05)-(-0.02) MPa.

[0052] Preferably, an annular sealing ring 6 may be provided at the connection between the tank connector 3 and the tank body 11. When the tank connector 3 and the tank body 11 are connected, the sealing ring 6 is attracted by the negative pressure within the tank body 11 to seal the connection between the tank connector 3 and the tank body 11, further ensuring the stability of the negative pressure within the tank body 11. The connection between the tank connector 3 and the tank body 11 may be threaded or plugged.

[0053] The side of the chassis 1 is provided with a vacuum pump button 10 connected to the control device and several tank connector buttons 7. The vacuum pump button 10 is used to start and close the vacuum pump 15. In the initial state, the vacuum pump 15 can be started by the vacuum pump button 10, so that the negative pressure chamber 13 is reduced to P0-ΔP and is ready for use. The tank connector button 7 is used to open and close the electromagnetic three-way valve 12, and a warning light 8 is provided inside the tank connector button 7 for observing the current working status. Preferably, each tank connector button 7 corresponds to each tank connector 3, that is, one tank connector button 7 is used to control the electromagnetic three-way valve 12 on one negative pressure tube 4.

[0054] Under normal conditions, that is, when the tank connector button 7 is not pressed, it is in the XA passage state, the negative pressure chamber 13 is blocked, the tank body 11 is in a normal pressure state, and the warning light 8 is constantly red.

[0055] When the tank connector button 7 is pressed, the corresponding electromagnetic three-way valve 12 is energized, switching the channel to the BA passage, the X port is blocked, and negative pressure is continuously provided to the tank body 11, so that the tank body 11 adsorbs the skin, and the warning light 8 is displayed in green.

[0056] When the tank connection button 7 is pressed again, the electromagnetic three-way valve 12 is de-energized. Under the action of the spring force, the switching channel returns to the XA passage state, the negative pressure chamber 13 is blocked, the tank body 11 is depressurized, and the warning light 8 turns red and lights up steadily, ready for use again.

[0057] To facilitate the use of the tank joint 3, several grooves can be set on the top of the chassis 1 for placing the tank joint 3, and a reel with a spring can be set inside the chassis for winding the negative pressure tube 4, and the reel is provided with a fixing structure to facilitate fixing the length of the stretched negative pressure tube 4.

[0058] To facilitate observation of the skin during cupping, a camera 5 is provided within the cupping joint 3. The camera 5 is connected to a control device via a first cable. The control device includes an image processing module. The camera 5 is used to capture a planar image of the skin within the cupping area and feed the planar image back to the control device. The control device uses the image processing module to identify whether blisters are present in the planar image. If blisters are present, the identified blister information is fed back to the control device. The control device then determines based on the blister information whether to de-energize the electromagnetic three-way valve 12. Specifically:

[0059] The bubble information includes the number n of bubbles and the area S=a*b of the bubble, where a is the width of the bubble and b is the length of the bubble.

[0060] The judgment rules are:

[0061] When n≥n0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar; n0 is the preset number of blisters;

[0062] When a≥a0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar; a0 is the preset width of the bubble;

[0063] When b≥b0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar; b0 is the preset length of the bubble;

[0064] When S≥S0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar; S0 is the preset area of ​​the bubble.

[0065] n0, a0, b0, and S0 are all preset safety values.

[0066] Preferably, n0=3, a0=b0=2mm, S0=1mm can be set 2 .

[0067] The image processing module is used to process planar images and extract image features.

[0068] For example:

[0069] Because camera 5 continuously and stably records the local skin within tank body 11, it captures multiple images of the same skin area at different times, using time as a coordinate. Consequently, these consecutive images are highly similar. When a blister forms on the skin, only the images of the blister area differ; the images of the area outside the blister remain the same.

[0070] Therefore, an image processing method can be used to obtain non-redundant information by comparing the initial image with the later acquired image, thereby obtaining a blister image and then obtaining the blister information therein. In image processing, data redundancy refers to unnecessary or repeated information contained in an image.

[0071] Specifically,

[0072] 1. Camera 5 obtains image Ia(x) of the original image I(x). Since the original image obtained by camera 5 is stored in RGB color space, it is necessary to first convert the RGB color space image I(x) into the Lab color space image. However, there is no direct conversion formula between RGB and Lab. An intermediate conversion must be performed. First, the RGB color space image is converted to XYZ space, and then the image Ia(x) is obtained through the XYZ space, as shown in the following formula:

[0073] RGB to XYZ:

[0074]

[0075] Where r, g, and b are the channel values ​​of R, G, and B of the RGB image respectively.

[0076] XYZ to Lab:

[0077] a*=500[f(X / Yn)-f(Y / Yn)] (4)

[0078]

[0079] Where Yn=100.0,

[0080] Therefore, we obtain the image Ia(x), as shown below:

[0081] Ia(x) = 500[f(X(x) / Yn)-f(Y(x) / Yn)] (5)

[0082] 2. Determine the similarity between adjacent two images

[0083]

[0084] where t is the serial number of the video time-sequence frame image, n is the total number of pictures in the sequence image data, and M*N is the size of a single sequence image.

[0085] |mean m -mean m+1 | ≤ T v , 1 ≤ m < n(7)

[0086] If the difference between adjacent two images is less than the threshold value Tv (according to actual observation and statistics, the best effect is achieved when Tv = 2), then these adjacent two images are similar. Among them, meanm = mean0.

[0087] 3. Extract the key frame summary of the similar segments of the WCE sequence images

[0088] Step 1: Assume that there are n frames in the time-sequence images. Cut each image in turn, remove the irrelevant edges and black corners, and obtain I1, I2…In cut image data and the image sequence pairs for similarity determination (I1, I2), (I2, I3)…(In-1, In). Initialize i = 1, m = 1, k = 1;

[0089] Step 2: First obtain the perceptual color images Iai(x) and Ia ( [[ID=三十二]]i +1) (x) of the sequence pair (Ii, Ii+1), i < n according to formulas (1) to (5);

[0090] Step 3: Determine the visual perceptual color similarity of the two images Ii(x) and Ii+1(x) according to formulas (6) to (7). If they are similar, then i = i + 1, and sequentially take the next sequence pair (Ii, Ii+1) to execute Step 6 until (Ii, Ii+1) is not similar. Record the dissimilar images Im(x) and Im+1(x), where m = i.

[0091] 4. Feature extraction

[0092] The image was binarized and segmented using adaptive thresholding, with pixels with grayscale values ​​greater than the threshold set to white and those below the threshold set to black. Skeletonization of the binary image was used to extract the skeletal features of the blisters. Specifically, the Guo-Hall Thinning8-neighborhood thinning algorithm was used to generate the skeleton structure lines of the binary image region. Blister information was then extracted, including the number of blisters n and their area S = a*b, where a is the width of the blisters and b is their length.

[0093] When n≥n0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar;

[0094] When a≥a0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar;

[0095] When b≥b0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar;

[0096] When S≥S0, the control device drives the electromagnetic three-way valve 12 to switch the channel to relieve the pressure of the cupping jar;

[0097] n0, a0, b0, and S0 are preset parameters, which are the preset number, preset width, preset length, and preset area of ​​bubbles, respectively.

[0098] For example, when n0=3 is preset, three blisters are generated, regardless of their size. When three blisters are detected on the skin, the control device switches channels to protect the skin and actively cuts off the cupping process.

[0099] The image processing and feature extraction in the present invention may also adopt other methods that can obtain the same results.

[0100] The first cable and the negative pressure tube 4 can be concentrated in the harness tube 2, and the harness tube 2 can be managed by the reel.

[0101] In addition to the blisters caused by the strong negative pressure on the local skin, cupping methods such as fire cupping and medicine cupping will produce thermal stimulation to the skin through a certain amount of heat, and this temperature is usually uncontrollable; some artificial integrated tank bodies 11 are equipped with heating devices and corresponding temperature sensing devices for controlling the temperature. However, in fact, when the temperature of the tank body 11 adsorbed on the human skin rises, even if the heating is stopped, the heat will still accumulate in the tank body 11, and it will not be effectively cooled or dissipated. The skin will continue to feel hot and may even cause damage, such as blisters, in a short period of time.

[0102] Therefore, a second cable connected to the control device can be added in the wiring harness tube 2, and the other end of the second cable is connected to the temperature sensor in the tank joint 3. The control device drives the electromagnetic three-way valve 12 to switch the channel according to the feedback of the temperature sensor to relieve the pressure of the cupping jar.

[0103] During the negative pressure supply process, the control device drives the electromagnetic three-way valve 12 to switch the channel under the premise that the cup connector button 7 is not pressed. When the cupping jar is depressurized, the warning light 8 flashes red to remind medical staff that it is an abnormal state, so as to facilitate timely diagnosis and treatment of the cupping patient.

[0104] Preferably, a display screen is provided on the side of the chassis 1 for displaying a planar image of the skin in the tank body 11 and information about blisters in the planar image. A number of parameter setting buttons are also provided on the side of the chassis 1 for setting preset parameters such as n0, a0, b0, and S0.

[0105] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of the present invention.
