Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine physiotherapy, specifically relating to a knee fumigation device for traditional Chinese medicine physiotherapy. Background Technology

[0002] Traditional Chinese medicine (TCM) is a long-standing medical practice that emphasizes holistic balance and natural treatment methods. Knee problems are common in TCM, including arthritis and sprains. Traditionally, TCM advocates using herbal fumigation therapy to promote blood circulation, relieve pain, and accelerate recovery. Fumigation allows the active ingredients released by the herbs to penetrate the skin and reach the knee joint, promoting blood circulation, relieving pain, reducing inflammation and swelling, and thus treating knee injuries. However, current knee fumigation devices simply spray steam onto the knee, which can easily lead to waste of steam and medicinal solutions and may reduce the effectiveness of the fumigation. Furthermore, directly applying steam to the knee in an exposed environment leaves the knee unprotected, increasing the risk of colds and other knee problems. Some devices wrap the knee completely, with the steam trapped inside, severely restricting knee movement. During prolonged fumigation, the knee may be immobile, sometimes even causing difficulty urinating.

[0003] In summary, the problems with the existing technology are as follows:

[0004] 1. Existing traditional Chinese medicine physiotherapy knee fumigation devices severely restrict the patient's knees, limiting their movement;

[0005] 2. Existing TCM physiotherapy knee fumigation devices cannot adjust the fixing device according to patients of different body types, resulting in some patients being unable to use TCM physiotherapy knee fumigation devices;

[0006] 3. Existing TCM physiotherapy knee fumigation devices are troublesome to replace the medicinal solution in the fumigation steam generator, and the device is also troublesome to clean after the fumigation is completed. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention designs a knee fumigation device for traditional Chinese medicine physiotherapy. By incorporating a quantitatively adjustable and rotatable fumigation device, the problems of cumbersome medication replacement and device cleaning are solved. A fixing device is included, whose diameter can be adjusted according to the patient's leg size to accommodate patients of different body types. A flexible connecting element is provided in the middle of the fixing device to facilitate patient movement.

[0008] To achieve the above-mentioned technical effects, the present invention is implemented through the following technical solution: a traditional Chinese medicine physiotherapy knee fumigation device, comprising: a fumigation device, a fixation device, and a conduit;

[0009] The fumigation device is movably connected to the fixed device via a conduit;

[0010] The fixing device includes a fixing mechanism and a plastic corrugated pipe. The fixing mechanism is connected to both ends of the plastic corrugated pipe. The fixing mechanism includes a sleeve, a threaded sleeve, a threaded pipe, a first telescopic component, a second telescopic component, an arc-shaped plate, and a plastic layer. The sleeve is divided into an upper sleeve and a lower sleeve. The lower end of the upper sleeve has an annular groove for movably connecting to the threaded sleeve. A plastic layer is provided on the inner wall of the upper sleeve. The front end of the plastic layer is fixedly connected to the arc-shaped plate. Multiple hinge components are arrayed on the inner wall of the lower end of the plastic layer of the upper sleeve, and several first telescopic components are hinged to the hinge components. The upper end of the lower sleeve has an annular groove for movably connecting to the threaded pipe. Multiple hinge components are arrayed on the inner wall of the lower sleeve. Several hinged components are used to hinge a second telescopic component. The inner wall of the threaded sleeve is threadedly connected to a threaded tube. A double-layered annular pressure rod is provided on the inner wall of the upper end of the threaded tube. The second telescopic component is movably installed in the middle of the double-layered annular pressure rod. The upper end of the telescopic sleeve is hinged to a first telescopic component. By controlling the rotation of the threaded sleeve, the threaded tube is driven to move up and down along the annular groove of the lower sleeve. The double-layered annular pressure rod on the inner wall of the threaded tube drives the second telescopic component to rotate around the lower hinge point. The front end of the first telescopic component is fixedly connected to an arc-shaped plate, and the lower part of the front end is hinged to the second telescopic component. By rotating the second telescopic component around the lower hinge point, the first telescopic component drives the arc-shaped plate to move back and forth.

[0011] The plastic corrugated pipe is rotatable and ensures a tight seal;

[0012] The fumigation device includes a housing, a temperature control mechanism, a cleaning mechanism, a drug injection mechanism, and an integrated display screen. The housing is hollow inside, with a heating element and temperature sensor installed at the bottom for temperature control. The cleaning mechanism is installed in the middle cavity, and the drug injection mechanism is fixedly installed at the top. The integrated display screen is fixedly installed on the upper outer wall, and a conduit is fixedly installed in the middle. The integrated display screen has a microcontroller for the temperature control mechanism, a switch for the cleaning mechanism, and an analog-to-digital converter for the drug injection mechanism embedded inside. The cleaning mechanism includes a tray, a pressure pump, a motor, a spray pipe, and a switch. The tray is movably installed in a circular hole in the middle of the housing, with a hollow cylinder in the middle. The outer wall of the hollow cylinder is equipped with gears that mesh with the motor output shaft. The pressure pump is fixedly installed on the upper outer periphery. The tray is hollow inside, and the spray pipe is fixedly connected to the lower end. The motor is fixedly installed on the upper inner wall of the housing. When the switch is turned on, the motor drives the tray to rotate around the circular hole. The pressure pump pumps pressurized external rinsing liquid, which is injected into the tray and sprayed into the internal cavity of the fumigation device through the spray pipe to rinse the fumigation device.

[0013] The injection mechanism includes a funnel, a solenoid valve, a flow sensor, and an analog-to-digital converter. The lower end of the funnel is movably connected to the solenoid valve and the flow sensor, and the tail end of the funnel is fixedly connected to the housing. The injection volume is set through an integrated display screen, and the flow sensor detects the injection volume. When the calibrated injection volume is reached, the analog-to-digital converter controls the solenoid valve to close and stop the injection.

[0014] Furthermore, the sleeve is divided into an upper sleeve and a lower sleeve, with a diameter range of 20-30 cm;

[0015] Furthermore, the telescopic range of the first telescopic component is 10-15cm;

[0016] Furthermore, the maximum telescopic length of the second telescopic member is greater than the vertical distance from the lower hinge of the second telescopic member to the first telescopic member;

[0017] Furthermore, the integrated display internally houses a microcontroller for the heating mechanism, a switch for the cleaning mechanism, and an analog-to-digital converter for the drug injection mechanism. The heating temperature, drug injection volume, and opening and closing of the cleaning mechanism can be set by clicking the touch screen.

[0018] Furthermore, the temperature control mechanism includes a heating element, a temperature sensor, and a microcontroller. The heating element and the temperature sensor are movably mounted at the bottom of the housing, and the operation of the heating element is controlled by the microcontroller.

[0019] Furthermore, the threaded sleeve is a hollow cylinder with threads on the outer wall and several connecting rods arranged in a row on the upper end of the inner wall. The front end of the connecting rods is connected to a double-layered annular rod, and a telescopic component two is movably installed inside the double-layered annular rod.

[0020] The beneficial effects of this invention are:

[0021] This invention designs a knee fumigation device for traditional Chinese medicine physiotherapy, and sets up a fixing device, which includes a plastic corrugated pipe and a fixing mechanism. By setting up the fixing mechanism, rotating the threaded sleeve drives the threaded pipe to move up and down. The double layer at the front end of the threaded rod drives the second telescopic component to rotate around the lower hinge position. The rotation of the second telescopic component around the lower hinge position drives the upper telescopic mechanism to move back and forth. The back and forth movement of the arc plate is controlled to adapt to patients of various body types, solving the problem that the existing device is not adjustable and some patients cannot use the fumigation device.

[0022] The plastic corrugated tube is flexible and rotatable. After connecting the fixing mechanisms at both ends, the patient's knees can bend and move through the plastic corrugated tube, which solves the problems in the existing technology where patients cannot move when they are fumigating, resulting in discomfort from sitting for a long time or difficulty in using the toilet.

[0023] The fumigation device is equipped with a cleaning mechanism. By turning on the switch on the integrated display screen, the pressure pump and motor work to draw the cleaning solution into the tray. The cleaning solution in the tray is then injected into the internal cavity of the fumigation device through the spray nozzle. The motor drives the tray and spray nozzle to rotate and clean more thoroughly. This solves the problem in the existing technology that it is necessary to open the cover and take out the internal medicine storage chamber for manual cleaning, which is troublesome.

[0024] With the injection mechanism set up, doctors only need to pour the fumigation solution into the funnel, set the injection volume, and once the injection volume is reached, the analog-to-digital converter can control the solenoid valve to close, eliminating the need to manually measure and control the injection volume before fumigation.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention; obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1

[0044] like Figure 1 and Figure 2 The diagram shows the overall structure of the device of the present invention. As shown, in this invention, two symmetrical fixing mechanisms are provided. One fixing mechanism fixes the patient's thigh, and the other fixing mechanism fixes the lower leg. They are connected by a plastic corrugated tube 13. The plastic corrugated tube 13 is a hollow cylindrical plastic pipe with a corrugated structure, composed of a series of interconnected nested corrugations, resembling a wave shape. It has elasticity and expandability. The two fixing mechanisms are connected by the plastic corrugated tube 13. The patient passes their leg through the fixing device from top to bottom. After being fixed by the fixing mechanism, the plastic corrugated tube 13 is positioned directly above the knee. Because the plastic corrugated tube 13 is elastic and expandable, the knee can move freely, achieving the desired effect. Figure 1 The arbitrary bending shown;

[0045] In this embodiment, a plastic corrugated tube 13 is provided, which connects the fixing mechanisms at both ends. The plastic corrugated tube 13 is positioned directly opposite the patient's knee, allowing the patient to move normally and bend the plastic corrugated tube 13 without affecting the fixation of the fixing mechanisms at both ends or the comfort of the patient's knee. Furthermore, it does not affect the continuation of fumigation, thus solving the problem in the prior art where the fumigation device severely restricts the patient's legs and prevents the patient from bending their knees.

[0046] Example 2

[0047] like Figure 4 The diagram shown is a cross-sectional view of the fixing device of the present invention. In this invention, a fixing mechanism is provided, comprising a sleeve 8, a threaded sleeve 87, a threaded tube 9, a first telescopic member 111, a second telescopic member 112, an arc-shaped plate 10, and a plastic layer. The sleeve 8 is divided into an upper sleeve 8 and a lower sleeve 8. The lower end of the upper sleeve 8 has an annular groove for movably connecting to the threaded sleeve 87. A plastic layer is provided on the inner wall of the upper sleeve 8, and the front end of the plastic layer is fixedly connected to the arc-shaped plate 10. Multiple hinge members are arrayed on the lower inner wall of the plastic layer of the upper sleeve 8, and several first telescopic members 111 are hinged to the hinge members. The upper end of the lower sleeve 8 has an annular groove for movably connecting to the threaded tube 9. Several hinge members are arrayed on the inner wall of the lower sleeve 8, and second telescopic members 112 are hinged to the hinge members. The inner wall of the threaded sleeve 87 is threaded with threads. The upper inner wall of the threaded tube 9 is provided with a double-layer annular pressure rod, and the middle of the double-layer pressure rod is movably installed with a second telescopic component 112. The upper end of the telescopic sleeve 82 is hinged to the first telescopic component 111. By controlling the rotation of the threaded sleeve 87, the threaded tube 9 is driven to move up and down along the annular groove of the lower sleeve 8. The double-layer annular pressure rod on the inner wall of the threaded tube 9 drives the second telescopic component 112 to rotate around the lower hinge. The front end of the first telescopic component 111 is fixedly connected to the arc plate 10, and the lower part of the front end is hinged to the second telescopic component 112. By rotating the second telescopic component 112 around the lower hinge, the first telescopic component 111 drives the arc plate 10 to move back and forth. This allows the diameter of the fixing device to be adjusted arbitrarily according to the different leg thicknesses of different patients and the different leg thicknesses of the same patient, adapting to the patient's leg and fixing the entire device to the patient's leg.

[0048] In this embodiment, a fixing mechanism is provided. By rotating the threaded sleeve 87, the threaded tube 9 moves up and down in the annular groove at the upper end of the lower sleeve 8. The double-layer annular rod at the front end of the threaded tube 9 drives the telescopic mechanism 2 in the middle to rotate around the hinge point with the lower sleeve 8. The forward and backward rotation of the telescopic mechanism 2 drives the telescopic mechanism 1 to move forward and backward, which in turn drives the arc plate 10 at the front end of the telescopic mechanism to move forward and backward, adjusting the relative distance of several arc plates 10 inside the fixing mechanism, so as to achieve the purpose of being suitable for patients of different body types.

[0049] In this embodiment, the sleeve 8 is divided into an upper sleeve 8 and a lower sleeve 8, with a diameter range of 20-30cm;

[0050] The telescopic range of the telescopic component 111 is 10-15cm;

[0051] The maximum telescopic length of the second telescopic member 112 is greater than the vertical distance from the lower hinge point of the telescopic member to the first telescopic member 111.

[0052] Example 3

[0053] like Figure 7 The diagram shows the structure of the cleaning mechanism of the present invention. The cleaning mechanism includes a tray, a pressure pump 15, a motor 5, a spray pipe 14, and a switch. The tray is movably installed in a circular hole in the middle of the housing 1. A hollow cylinder is provided in the middle. The outer wall of the hollow cylinder is equipped with gears that mesh with the output shaft of the motor 5. The pressure pump 15 is fixedly installed on the outer periphery of the upper end. The tray is hollow inside and the spray pipe 14 is fixedly connected to the lower end. The motor 5 is fixedly installed on the upper inner wall of the housing 1. When the switch is turned on, the motor 5 drives the tray to rotate around the circular hole. The pressure pump 15 pumps pressurized external rinsing liquid and injects it into the inside of the tray. The spray pipe 14 then sprays the liquid into the internal cavity of the fumigation device to rinse the fumigation device.

[0054] In this embodiment, a cleaning mechanism is provided. By activating the switch on the integrated display screen 3, the pressure pump 15 and motor 5 start working. The pressure pump 15 draws the cleaning liquid into the tray, and sprays the cleaning liquid into the internal cavity of the fumigation device through the spray pipe 14. The motor 5 drives the tray to rotate, which in turn drives the spray pipe 14 to rotate and spray the internal cavity of the fumigation device, achieving the purpose of thorough cleaning. This avoids the need for manual cleaning of the fumigation device, which is troublesome and time-consuming.

[0055] Example 4

[0056] like Figure 6 The diagram shown is a schematic diagram of the fumigation device of the present invention. In this embodiment, a drug injection device is provided. The drug injection mechanism includes a funnel 16, a solenoid valve 4, a flow sensor, and an analog-to-digital converter. The lower end of the funnel 16 is movably connected to the solenoid valve 4 and the flow sensor. The tail end of the funnel 16 is fixedly connected to the housing 1. The drug injection amount is set through the integrated display screen 3. The flow sensor detects the drug injection amount. When the calibrated drug injection amount is reached, the solenoid valve 4 is closed through the analog-to-digital converter to stop the drug injection.

[0057] In this embodiment, an injection mechanism is set up. The injection volume can be set by the analog-to-digital converter on the integrated display screen 3. After the setting is completed, the solenoid valve 4 opens and the medicine flows into the lower fumigation device. The injection volume is monitored in real time by the flow sensor. When the set injection volume is reached, the analog-to-digital converter controls the solenoid valve 4 to close, and the medicine injection is completed. This solves the problem of the troublesome injection process in the prior art, which requires manual measurement of the injection volume in advance and then pouring it into the fumigation device.

[0058] In summary, this invention provides a traditional Chinese medicine physiotherapy knee fumigation device with a fixing device, which includes a plastic corrugated pipe 13 and a fixing mechanism. By setting the fixing mechanism, rotating the threaded sleeve 87 drives the threaded pipe 9 to move up and down. The double-layered extension member 112 at the front end of the threaded rod rotates around the lower hinge position. The rotation of the extension member 112 around the lower hinge position drives the upper extension mechanism 1 to move back and forth, controlling the back and forth movement of the arc plate 10 to adapt to patients of various body types. This solves the problem in the prior art that the device is not adjustable and some patients cannot use the fumigation device.

[0059] The plastic corrugated tube 13 is flexible and rotatable. After connecting the fixing mechanisms at both ends, the patient's knees can bend and move through the plastic corrugated tube 13, which solves the problems in the prior art where patients cannot move when fumigating, leading to discomfort from prolonged sitting or difficulty in using the toilet.

[0060] The fumigation device is equipped with a cleaning mechanism. By turning on the switch on the integrated display screen 3, the pressure pump 15 and motor 5 work to draw the cleaning liquid into the tray. The cleaning liquid in the tray is injected into the internal cavity of the fumigation device through the spray pipe 14. The motor 5 drives the tray and spray pipe 14 to rotate and clean, making the cleaning more thorough. This solves the problem in the existing technology that it is necessary to open the cover and take out the internal medicine storage chamber for manual cleaning, which is troublesome.

[0061] With the injection mechanism set up, doctors only need to pour the fumigation solution into the funnel 16, set the injection volume, and once the injection volume is reached, the analog-to-digital converter can control the solenoid valve 4 to close, eliminating the need to manually measure and control the injection volume before fumigation.

[0062] The preferred embodiments of the present invention disclosed above are only for the purpose of illustrating the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation described.
