Description

Technical Field

[0001] The present invention relates to the technical field of rheumatism external application devices, and in particular to a rheumatism external application device with an auxiliary heating function. Background Art

[0002] Currently, the treatment methods for rheumatism mainly include oral administration and external application. Although oral medications can achieve certain treatment effects in the short term, their drawbacks cannot be ignored. On the one hand, this method has a difficult-to-sustain curative effect on rheumatism; on the other hand, long-term use of oral medications will bring a greater burden to organs such as the kidneys and liver of patients, and may even cause organ lesions, threatening the health of patients. Currently, for rheumatism, especially chronic rheumatism, the treatment method is mostly external application. External application is further divided into drug external application and non-drug external application. Medical research shows that moderately warm external application can significantly improve the treatment effect of rheumatism, especially for patients with chronic rheumatism.

[0003] For example, the patent application document with the Chinese invention publication number CN114733059A discloses a rheumatism external application device with an auxiliary heating function. Although this device can perform auxiliary heat treatment on the rheumatism external application package by installing a heating module, which helps to promote the rapid exertion of drug efficacy, is warmer and more comfortable to use in the cold seasons of autumn and winter, and is convenient to move the external application position, there are still the following problems in the process of use, that is, it is difficult to achieve high-degree adaptive tracking of the patient's neck shape to ensure stable transmission and accurate positioning during the treatment process, and there are still certain limitations in promoting the exertion of drug efficacy only by the method of heat-assisted external application.

A sewage discharge port is opened on one of the mounting plates, and the sewage discharge port is located at the lowest point of the diversion plate. A sewage collection box is detachably mounted on the mounting plate, and the sewage collection box is connected to the sewage discharge port through a pipeline.

[0017] Compared with the existing technology, the advantages of the present invention are as follows:

[0018] 1. In this device, multiple rollers with silica gel layers are symmetrically arranged in the external application device. The rollers are installed on the guide rods and move up and down along the guide under the action of the first spring, realizing precise fitting to the neck; the silica gel layer improves the contact comfort, and the guide rail seat and rotating shaft structure ensure that the rollers can freely rotate and slide in multiple directions, providing a stable, fitting and comfortable basic environment for subsequent treatment.

[0019] 2. This device is equipped with a stainless steel conveyor belt and guide wheels. Through the front and rear open design of the guide rail, the guide wheels are smoothly guided to enter and slide along the guide rail; as the rollers are pressed down by force, the support carries the guide rail seat to move, and the guide rail bends and slides in the chute and rotates around the rotating shaft, ensuring the smooth cooperation between the conveyor belt and the guide rail; through the coordinated action of the guide wheels and the guide rail, the stainless steel conveyor belt realizes highly adaptive tracking of the shape of the patient's neck, ensuring stable transmission and precise positioning during the treatment process.

[0020] 3. During the treatment process of this device, the first auxiliary heating rod and the second auxiliary heating rod heat the water in the first material box to about 42°C. The charged spray head charges the atomized water droplets positively and then slowly sprays them upward; the negatively charged skin surface combines with the positively charged water droplets, and the neck warms up under the fumigation, the blood vessels dilate, the circulation is enhanced, and the pain sensitivity is reduced, realizing the relief of soreness and pain; the condensed water droplets converge to the sewage collection box through the inclined diversion plate. At the same time, the cleaning sponge and the wool felt wipe the neck to remove sweat and stains, keep the skin clean, and prevent cross-infection.

[0021] 4. After the water mist fumigation and cleaning are completed, the charged spray head charges the rheumatism medicine liquid positively and atomizes and sprays it. Because the temperature of the lesion area is relatively high and dry, more negative charges accumulate on the skin surface, prompting the atomized medicine liquid to preferentially adhere to the lesion; then the stainless steel conveyor belt moves the penetration promoting part close to the neck, and under the action of electrostatic repulsion, the penetration of the medicine liquid into the dermis layer is enhanced, improving the targeted absorption efficiency; this process significantly reduces the systemic drug dose and side effects, and is especially suitable for patients with drug intolerance and long-term medication, improving the treatment safety and effect.

[0022] In summary, the present device realizes the fitting and comfortable support for the neck through the headrest and the silica gel rollers, and cooperates with the heating, ionization of water mist and cleaning and wiping to effectively relieve pain, keep the skin clean and prevent cross-infection; then, by using the targeted aggregation of static charges and the drug penetration acceleration part to accelerate the penetration of the medicinal liquid, the absorption rate of the lesion is significantly improved, the systemic side effects of the drug are reduced, and the rheumatic symptoms are improved.

Detailed Embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Refer toFigures 1 to 7 , a rheumatism external application device with auxiliary heating function, which is applied to the treatment of cervical rheumatism, including a headrest 1 and an external application device 2. The headrest 1 is placed on one side of the external application device 2 for the patient to support the head, while the external application device 2 is aligned with the patient's neck and acts on the patient's neck.

[0033] The external application device 2 includes two parallel mounting plates. A stainless steel conveyor belt 23 is installed between the two mounting plates. The stainless steel conveyor belt 23 is a prior art, and its specific structural design will not be elaborated here. The stainless steel conveyor belt 23 is positively charged, and a hollow part 231 is provided on one side of the surface of the stainless steel conveyor belt 23. On the other side, a cleaning sponge 28 and a wool felt 29 are sequentially installed by means of magic tape or bonding. A drug penetration promoting part 232 is provided on a section of the stainless steel conveyor belt 23 between the hollow part 231 and the cleaning sponge 28. The drug penetration promoting part 232 keeps a certain distance from the patient's neck during use, and promotes the penetration of the liquid medicine into the skin through the dermis under the action of positive electric repulsion to improve the absorption efficiency.

[0034] A plurality of supports 211 are linearly arrayed at the middle position above the mounting plate. A roller 21 is rotatably installed inside the support 211. A silica gel layer is bonded to the surface of the roller 21 to improve the comfort of the patient. Both sides of the lower end of the support 211 are fixedly connected with guide rods 214. The lower ends of the guide rods 214 are located inside the mounting plate and are slidably connected to the mounting plate, so that the support 211 can move up and down in the vertical direction. A first spring 213 is fixedly connected to the middle position of the lower end of the support 211. The lower end of the first spring 213 is fixedly connected to the top surface of the mounting plate. The roller 21 contacts the patient's neck and is pressed down by a certain distance accordingly. The first spring 213 ensures the close contact between the roller 21 and the patient's neck.

[0035] A rotating shaft 2111 is fixedly connected to one side of the support 211 close to the stainless steel conveyor belt 23. The rotating shaft 2111 itself does not rotate. A guide rail seat 212 is rotatably sleeved on the rotating shaft 2111. A guide rail 216 is slidably penetrated through the inside of a plurality of guide rail seats 212 on the same side. The guide rail 216 is made of a deformable material, so that the guide rail 216 can generate corresponding deformation following the up and down movement of the support 211. A plurality of guide wheels 233 are rotatably connected to both sides of the stainless steel conveyor belt 23. A chute 2161 is provided inside the guide rail 216. The guide wheels 233 are located inside the chute 2161 and are rotatably connected to it. The stainless steel conveyor belt 23 can generate corresponding deformation following the guide rail 216.

[0036] Openings are provided at both the front and rear ends of the guide rail 216 (as shown in the attached instructions Figure 4As shown, on the one hand, the opening can prevent the guide rail 216 from slipping out of the guide rail seat 212, and on the other hand, it can guide the guide wheels 233 on the stainless steel conveyor belt 23, so as to ensure that the guide wheels 233 smoothly enter the guide rail 216. One end of the mounting plate is provided with a moving groove penetrating left and right. The end of the driven wheel in the stainless steel conveyor belt 23 is slidably and rotatably connected to the moving groove, and a second spring 221 is fixedly connected between the end of the driven wheel and the inner wall of the moving groove, which is beneficial to the corresponding deformation of the stainless steel conveyor belt 23.

[0037] A support plate is fixedly connected between the mounting plates. The support plate is located inside the stainless steel conveyor belt 23. A first material box 217 and a second material box 218 are fixedly installed on the upper end of the support plate. A first auxiliary heating rod 219 is arranged inside the first material box 217, and a second auxiliary heating rod 220 is arranged inside the second material box 218. Both the first auxiliary heating rod 219 and the second auxiliary heating rod 220 are electrically connected to an external power supply device. One end of the first material box 217 is communicated with a first liquid pipe 26, and one end of the second material box 218 is communicated with a second liquid pipe 27. Through holes 24 are opened on both the front and back sides of the mounting plate. Both the first liquid pipe 26 and the second liquid pipe 27 pass through the through holes 24 and extend to the outside. Water is stored in the first material box 217, and rheumatism liquid medicine is stored in the second material box 218. A plurality of charged spray nozzles 22 are installed on the tops of both the first material box 217 and the second material box 218. The charged spray nozzles 22 are used to charge the sprayed liquid. A diversion plate 210 is provided above the first material box 217 and the second material box 218. The diversion plate 210 is inclined and its two ends are respectively fixedly connected to the corresponding mounting plates. The tops of the charged spray nozzles 22 pass through the diversion plate 210, so that the diversion plate 210 can collect the excess liquid and other waste liquid sprayed by the charged spray nozzles 22.

[0038] A sewage outlet 215 is opened on one of the mounting plates. The sewage outlet 215 is located at the lowest point of the diversion plate 210. A sewage collection box 25 is detachably installed on the mounting plate. The sewage collection box 25 is connected to the sewage outlet 215 through a pipeline. By setting the sewage outlet 215, the waste liquid can enter the sewage collection box 25 through the pipeline, so as to realize the collection of the waste liquid.

[0039] When the present application is working, first, ensure that the on-site environment is sufficiently suitable and comfortable. The patient places the head on the headrest 1 and places the neck on the external application device 2. The rollers 21 contact the patient's neck and are pressed down a certain distance accordingly. The first spring 213 ensures the close contact between the rollers 21 and the patient's neck. As the rollers 21 are pressed down accordingly, the support 211 carries the guide rail seat 212 to move. The guide rail 216 bends accordingly and slides within the guide rail seat 212. The guide rail seat 212 rotates a certain angle accordingly following the guide rail 216 to ensure the smooth bending and sliding of the guide rail 216.

[0040] The driven wheel on the stainless - steel conveyor belt 23 moves correspondingly to ensure the deformation of the stainless - steel conveyor belt 23. The stainless - steel conveyor belt 23 follows the guide rail 216 through the guide wheel 233, enabling the stainless - steel conveyor belt 23 to move along with the shape of the patient's neck. The second spring 221 ensures the reset of the driven wheel. At the same time, the stainless - steel conveyor belt 23 is positively charged. Medical staff draw out the first liquid pipe 26 and the second liquid pipe 27 through the maintenance port 24 and connect the interfaces to replace and supplement the stored liquid in the first material box 217 and the second material box 218.

[0041] Before the treatment starts, the stored liquid in the first material box 217 and the second material box 218 is heated to about 42 °C by the first auxiliary heating rod 219 and the second auxiliary heating rod 220. Then, the charged nozzle 22 sprays the atomized water droplets upwards slowly and evenly after charging them positively. The negatively charged skin quickly combines with the water droplets and is continuously fumigated by the temperature of the water droplets. Under the continuous fumigation, the patient's neck gradually warms up, causing the blood vessels in the patient's neck to dilate, increasing the blood flow and reducing the sensitivity of pain - sensing nerves, relieving the soreness and pain caused by rheumatism and improving the patient's comfort. At the same time, after the water droplets condense, they drip onto the inclined deflector 210 and finally drain into the sewage collection box 25 for collection. After a period of time, the charged nozzle 22 stops working. After waiting for about fifteen minutes and observing that the patient is no longer sweating, the device is started and the stainless - steel conveyor belt 23 rotates. The cleaning sponge 28 and the wool felt 29 are installed on the stainless - steel conveyor belt 23 through Velcro. As the stainless - steel conveyor belt 23 rotates, the cleaning sponge 28 wipes along the patient's neck to remove dirt such as water and sweat on the patient's neck skin to ensure cleanliness. Due to reasons such as the high blood flow velocity in the lesion area and continuous heat production by inflammatory cells, the cooling of the lesion area is significantly lower than that of normal tissues, making the temperature of the lesion area higher than that of the surrounding area and the water drying quickly. Subsequently, the wool felt 29 contacts and rubs against the neck skin, causing negative charges to accumulate on the skin surface. The more charges accumulate and are retained in the warmer and drier parts of the lesion area. Then, the charged nozzle 22 atomizes and sprays the rheumatism medicament after charging it positively. The positively charged atomized medicament quickly adheres to the skin surface. More medicament adheres to the lesion area with more negative charges. Then, the charged nozzle 22 stops working. The stainless - steel conveyor belt 23 rotates to move the penetration - promoting part 232 to a certain distance from the patient's neck. Under the action of positive - charge repulsion, the medicament is promoted to penetrate into the skin and pass through the dermis layer, greatly improving the absorption efficiency. The more medicament penetrates closer to the lesion area, enabling more medicament to directly act on the lesion area, enhancing the alleviating effect on inflammation and pain, and reducing the side effects of the drug on the whole body, which is especially suitable for patients intolerant to drugs or those who have been taking drugs for a long time. For rheumatism patients who need to take drugs for a long time, it greatly reduces the side effects of the drug and improves the patient's physical health.

[0042] Subsequently, the stainless-steel conveyor belt 23 rotates, and the cleaning sponge 28 and the wool felt 29 repeat the cleaning and charge loading operations. The previous external application operation is repeated to improve the remission and treatment effects on rheumatic diseases through liquid medicine fumigation and promoting penetration, and to eliminate the influence of dirt such as sweat in the conventional external application device on the treatment effect, ensuring cleaning, preventing cross-infection, and improving the quality of treatment and the patient experience.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
