Description

Technical Field

[0001] The invention relates to a medical device, in particular to a therapeutic device for acupoint medication. Background Art

[0002] Nowadays, with the development of society, people's living standards have improved, but more and more diseases have come along, which seriously threaten people's health. For the treatment of these diseases, people usually have to take medicine or be hospitalized. The hospitalization cost is high, the treatment effect is not ideal, the side effects of taking medicine are large, the treatment is not safe, the treatment cycle is long, the duration of drug effect is short, and the treatment effect is not good. Nowadays, people's health awareness has improved. With the development of science and technology, some high-tech medical and health care equipment have been produced, and the treatment method of acupoint medication has emerged.

[0003] In the existing medical treatment field, acupoint application or drug administration treatment methods achieve the purpose of rehabilitation treatment by preparing drugs and administering drugs to acupoints. This treatment method targets pain points or acupoints to treat internal diseases and external diseases, penetrates the skin, stimulates heat therapy, and quickly infiltrates all drugs into the affected area to quickly solve the problem. The effect is good and quick, avoiding the adverse reactions caused by various other moxibustion and external medications to the human body.

[0004] However, in the existing drug delivery treatment devices, when the top surface of the negative pressure chamber is connected to the negative pressure source, the air inlet is directly facing the skin, and the air is inhaled directly up and down. The silicone plate and the skin are both tough. As the pressure in the negative pressure chamber increases, the degree of deformation of the silicone plate and the skin increases, which causes the negative pressure air inlet to suck the skin. The overall treatment time is relatively long. The skin is under negative pressure for a long time, and blood marks are easily generated at the position of the air inlet.

[0005] Tablets soaked in Chinese medicine are attached to the bottom of the positive pressure chamber for heating. As the heating time increases, the drug content in the tablets gradually decreases, and the tablets themselves have their own gravity, which reduces the adhesion to the bottom of the tablets, making it easy to stick to the skin and cause burns to the skin. There will also be problems with insufficient heating of the medicine. In addition, when the negative pressure is working, part of the gas in the positive pressure chamber will be sucked away, causing negative pressure in the positive pressure chamber. The temperature sensor in the middle is installed in a place that is easy to contact with the skin, and it is easy to produce indentations during long-term treatment. The positive pressure chamber is prone to air leakage, and drug molecules are easy to escape, affecting the treatment effect. Summary of the invention

[0006] In order to overcome the technical deficiencies in the prior art of pills falling off and scalding people and temperature sensors leaving indentations on the skin, the purpose of the present invention is to provide a treatment device with an increased position in the medicine cabin, a pressurized positive pressure cabin, and a duckbill valve for the air inlet of the positive pressure cabin.

[0030] The present invention is further described in detail below in conjunction with the embodiments and drawings.

[0031] like Figure 1 As shown, the present invention comprises a mobile base 1 at the bottom, a housing 2 in the middle and a control mainboard inside, a water film instrument 3 outside the housing 2, an operating table 4 at the top, a disinfection cabin 5 at the upper front of the housing 2, a plurality of Y-shaped silica gel plates 6 in the disinfection cabin 5, and a storage compartment 7 at the lower front of the housing 2. A mobile base 1 is provided under the housing 2 to facilitate the movement of the instrument. The operating table 4 at the top of the housing 2 is a touch screen, which eliminates the need for keyboard operation and is practical.

[0032] The front part of the housing 2 is provided with a disinfection cabin 5, which is provided with an ultraviolet disinfection lamp, and the Y-shaped silicone plate 6 is disinfected by ultraviolet radiation after each use. The disinfection cabin 5 is provided with three Y-shaped silicone plates 6, and the ultraviolet disinfection lamp faces the Y-shaped silicone plates 6.

[0033] like Figure 1-Figure 9 As shown, the present invention is provided with a negative pressure source and a positive pressure source (an air suction pump and an air charging pump, respectively) in the housing 2. Figure 1 Three Y-shaped silicone plates 6 are shown in the figure. On the inner surface of each Y-shaped silicone plate 6, a concave negative pressure chamber 23 and a positive pressure chamber 33 are provided. The negative pressure chamber 23 is isolated from the positive pressure chamber 33 and does not cross-flow. A negative pressure air pipe 13 and a positive pressure air pipe 14 are provided on the handle on the outer surface of the Y-shaped silicone plate 6. The negative pressure chamber 23 is connected to the negative pressure source in the housing 2 in sequence through the negative pressure air passage 17 on the surface of the Y-shaped silicone plate 6, the negative pressure air pipe 13, the negative pressure air passage 16, and the negative pressure connecting pipe. The positive pressure chamber 33 is connected to the positive pressure source in the housing 2 in sequence through the positive pressure air passage 27 on the surface of the Y-shaped silicone plate 6, the positive pressure air pipe 14, the positive pressure air passage 15, and the positive pressure connecting pipe. Figure 1 There are no positive pressure or negative pressure connecting pipes.

[0034] like Figure 3-Figure 7As shown, the positive pressure airway 27 on the disk of the Y-shaped silicone disk 6 is connected to the positive pressure airway 15 on the handle, and the negative pressure airway 17 on the disk is connected to the negative pressure airway 16 on the handle, and the Y-shaped silicone disk 6 is fixedly connected to the handle as a whole. The pipe between the negative pressure airway 16 and the negative pressure airway 13 is the pipe of the handle, and the pipe between the positive pressure airway 15 and the negative pressure airway 13 is the pipe of the handle. The handle is provided with an integrated positive pressure pipe and a negative pressure pipe, as well as wires for the temperature sensor. The negative pressure airway 13 and the positive pressure airway 14 on the Y-shaped silicone disk 6 and the handle at the rear are Y-shaped. The positive pressure connecting pipe and the negative pressure connecting pipe are silicone pipes, which are durable and convenient. The positive pressure connecting pipe and the negative pressure connecting pipe are connected to the rear end of the handle. The wires of the temperature sensor are integrated with the positive pressure connecting pipe and the negative pressure connecting pipe in one pipe for transmission, which is both beautiful and practical.

[0035] An annular negative pressure cabin 23 is provided on the outer ring of the inner surface of the Y-shaped silicone plate 6, and an annular positive pressure cabin 33 is provided on the middle part of the inner surface of the Y-shaped silicone plate 6. The negative pressure cabin 23 is sleeved outside the positive pressure cabin 33, and the lower ends of the two are flush. The two are flush so that when the Y-shaped silicone plate 6 contacts the skin for treatment, there will be no air leakage to each other. The two sides of the negative pressure cabin 23 are the outer wall (including the left outer wall 19 and the right outer wall 20) and the inner wall (including the left inner wall 21 and the right inner wall 22), and the top is the first top wall 30. That is, the left outer wall 19 and the left inner wall 21, while the right inner wall 22 and the right outer wall 20, and the first top wall 30 form the negative pressure cabin 23. In terms of the negative pressure suction method, in the negative pressure cabin 23, the suction port of the negative pressure airway 17 on the disk is a horizontal side suction type. Adopt side suction to avoid direct suction, so as to avoid direct negative pressure adsorption of skin damage. The positive pressure cabin 33 has a left inner wall 21 and a right inner wall 32 on both sides and a second top wall 26 on the top. The inner wall, the right inner wall 32 and the second top wall 26 together form a positive pressure cabin 33 .

[0036] Figure 6 1 is a cross-sectional schematic diagram of a Y-shaped silicone plate 6 without a handle according to an embodiment of the present invention. Figure 7 AA is a cross-sectional view of the disk negative pressure airway 17. The disk negative pressure airway 17 leading down from the first top wall 30 turns 90 degrees and then opens, so that the suction airflow does not directly hit the skin and does not damage the skin. The width of the negative pressure chamber 23 is 0.3-1.0 cm. If it is too wide, the skin will be sucked into the negative pressure chamber 23, leaving suction marks on the skin.

[0037] like Figure 5 , Figure 6As shown, the center of the inner surface of the Y-shaped silicone plate 6 is convex downward toward the positive pressure cabin 33, so a groove is provided on the upper surface of the Y-shaped silicone plate 6, which is the temperature sensor mounting hole 31. The lower bottom end of the temperature sensor mounting hole 31 is higher than the bottom end of the negative pressure cabin 23 or the positive pressure cabin 33, and is 1.2 to 2.0 mm apart. A wire hole 18 is also provided on the handle on the upper surface of the Y-shaped silicone plate 6. The wires of the temperature sensor pass through the wire hole 18 of the handle. One end of the wire (heating wire and temperature control wire) passing through the wire hole 18 is respectively connected to the heating diaphragm 34 and the temperature sensor of the Y-shaped silicone plate 6, and the other end is also connected to the control main board inside the housing 2. The temperature sensor mounting hole 31 is installed to detect the temperature in the positive pressure cabin 33 and feed it back to the control main board for temperature control.

[0038] like Figure 5 , Figure 6 , Fig. 9 As shown, the second top wall 26 is annular, and the center thereof is a temperature sensor mounting hole. From the Y-shaped silicone plate 6 on both sides of the second top wall 26, a left wall 25 and a right wall 36 are provided upward, and the left wall 25 and the right wall 36 form a horizontal annular cabin 35. A heating diaphragm 34 is fixed in the annular cabin 35, and the lower surface of the heating diaphragm 34 contacts the second top wall 26. The heating diaphragm 34 is divided into a plurality of heating fan blades, so that the heating can be uniform. The lower surface of the second top wall 26 contacts and is fixed with a tablet 28.

[0039] A plurality of (four) bosses 29 are evenly arranged on the annular wall at the upper part of the positive pressure chamber 33 toward the center. The tablet 28 is clamped under the second top wall 26 by the four bosses 29 and one duckbill boss 29 to prevent the tablet 28 from falling off. By heating the tablet 28, the drug molecules can evaporate quickly to increase the therapeutic effect.

[0040] like Figure 6 , Figure 8 As shown, one side of the disk positive pressure airway 27 is connected to the left wall 25 as a whole. After the air outlet 24 of the disk positive pressure airway 27 turns ninety degrees, it is opened laterally toward the horizontal center of the positive pressure cabin 33 and is set as a one-way valve duckbill type. Among them, one end connected to the disk positive pressure airway 27 is wide, and one end of the air outlet 24 (duckbill boss 29) is narrow and flat, which is a silicone air outlet 24. A slit is made on the silicone air outlet 24. Because the silicone material is tough, it will not open by itself after the slit is made. It will only open when a certain pressure of gas passes through it, playing the role of a one-way valve to cut off the air flow. When the pressure reaches the standard, the positive pressure airway 15 stops supplying air, and the pressure in the positive pressure cabin 33 is greater than the pressure in the positive pressure airway 15, so the gap of the silicone air outlet 24 is pressed tightly to form a closed cabin.

[0041] A water film instrument 3 is provided on the housing 2 and fixed on one side of the housing 2. The housing 12 comprises a water storage tank 8 at the top, a spray port 9 at the bottom, a cold and hot spray switch 10, and a main power switch 11.

[0042] Working principle:

[0043] The drug molecules are evaporated by heating the tablets 28 in the Y-shaped silica gel disk 6, and then precisely targeted at the acupuncture points in the closed positive pressure chamber 33 to deliver the drugs and exert the therapeutic effect to achieve the therapeutic effect.

[0044] The negative pressure airway is connected to the negative pressure source, and the negative pressure source inhales air to make the negative pressure cabin 23 reach the pressure given by the system, sucking the skin. The positive pressure acts on the skin, so that the pores of the skin are opened, which is conducive to the penetration of drugs in the later treatment process. As time goes by, the temperature of the heating diaphragm 34 rises until it stabilizes to seventy (sixty-five-seventy-two) degrees. The heating diaphragm 34 heats the tablets 28 to make the drugs evaporate faster, and the concentration of drug molecules in the inner cabin continues to increase. The constant temperature also ensures the continuity of the pores opening, so that the drugs enter the acupuncture points and achieve the therapeutic effect. The existence of the negative pressure cabin 23 allows the entire positive pressure drug positive pressure cabin 33 to reach a sealed state, and the drug molecules are not easy to evaporate to the external environment, thereby increasing the amount of drug given. The Y-shaped silica gel plate 6 is relatively small and can find acupuncture points accurately. It is connected to the operating table 4 through a pipe made of silica gel, which also increases people's flexibility of use. Simple activities during treatment will not affect the therapeutic effect.

[0045] The steps of the application method of the present invention are:

[0046] (a) placing a number of Y-shaped silicone plates 6 on the surface of the acupuncture point skin;

[0047] (ii) starting the negative pressure source, connecting the negative pressure airway to the negative pressure source, and causing the negative pressure source to inhale air so that the pressure in the negative pressure chamber 23 reaches the pressure given by the system, and then stopping the operation;

[0048] (iii) Then the positive pressure source is started, the positive pressure airway is connected to the positive pressure source, the airflow rushes into the positive pressure cabin 33, and when a certain pressure is reached, the positive pressure source stops working;

[0049] (IV) Finally, the heating film 34 is heated. As time goes by, the temperature of the heating film 34 increases until it stabilizes at 65-72 degrees, preferably 70 degrees. The heat is conducted through the contact between the heating film 34 and the second top wall 26 to heat the medication sheet 28, evaporating the drug molecules to treat the acupuncture points. The temperature is maintained for 35-55 minutes until the treatment is completed.

[0050] Steps for using the water film instrument 3:

[0051] The penetration enhancer water storage tank of the water film apparatus 3 is filled with liquid soaked with the penetration enhancer.

[0052] First, a water film is sprayed on the acupuncture points with a water film instrument 3. The spray water temperature of the water film instrument 3 can be adjusted. There are two options: normal temperature and warm water. It can be adjusted according to needs. There is a heating furnace inside the water film instrument 3. The liquid is heated and sprayed out to form a spray of about 50 degrees and sprayed on the skin. Spraying a layer of water film on the acupuncture points is conducive to better fit between the Y-shaped silicone plate 6 and the skin, reducing the possibility of air leakage during treatment. Spraying a layer of water film on the acupuncture points is conducive to opening the acupuncture points and increasing the effect of treatment. The water film on the skin also plays a role in preventing scalds. If there are really scalded parts on the body, you can choose a cold spray port 9 to spray to relieve the pain. After applying the water film, control the equipment on the operating table 4, start the negative pressure source, and stop working when the negative pressure reaches the set pressure. The negative pressure cabin 23 fits tightly with the skin, so that the positive pressure cabin 33 forms a sealed space. The positive pressure starts to inflate the positive pressure cabin 33, and the positive pressure stops working when a certain pressure is reached. Due to the existence of positive pressure, the surface area of ​​the skin is compressed, so that the acupuncture points are easier to open. When the positive pressure ends, the control mainboard heats the heating diaphragm 34 and finally stabilizes it at about seventy degrees. The constant temperature ensures that the acupuncture points are always open, and the temperature also increases the concentration of the drug molecules in the positive pressure chamber 33, which is conducive to more drug molecules entering the body. The temperature is maintained for forty-five minutes until the treatment ends. After the treatment, take out the tablets 28, wipe the Y-shaped silicone plate 6 clean and put it into the disinfection chamber 5 for disinfection until the next use. This device uses a silicone pipe to connect the Y-shaped silicone plate 6 and the control mainboard (housing 2). During the treatment, the patient can move simply without affecting the treatment effect. The design of the Y-shaped silicone plate 6 can also accurately find the acupuncture points, and the device will not be unusable due to differences in body shape.

[0053] The technical principle and structure of the present invention are not limited to the above embodiments, and the approximate replacement and modification designs made by industry technicians are all to be protected by the present invention.
