Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an acupuncture treatment rehabilitation auxiliary device. Background Art

[0002] Acupuncture is a general term for both acupuncture and moxibustion. Acupuncture involves inserting needles at a specific angle, guided by Traditional Chinese Medicine (TCM) principles, to stimulate specific body parts using techniques such as twisting and lifting. Moxibustion involves heating acupuncture points to achieve the desired therapeutic effect. Currently, moxibustion heating is typically performed using fumigation, which can cause unintended harm to patients if not performed properly, and is unsafe.

[0003] In order to solve the above technical problems, a Chinese invention patent with authorization announcement number CN114869757B discloses a clinical acupuncture treatment device for rehabilitation department. The device is implemented by filling heating material in the tube body, and the tail end of the needle body is inserted into the tube body by a sealing plug. When the vent is in the conducting state, the outside air will enter the tube body through the vent, and the oxygen contained in the air will react with the heating material. The heating material heats the tail end of the needle body through the reaction heat, transfers the heat to the needle body, and then introduces the heat into the corresponding stimulation acupuncture point to achieve the moxibustion effect. It abandons open flames and uses controllable chemical reaction to generate heat, eliminating burns and fire hazards, and solving the technical problems of inconvenience and safety of traditional moxibustion.

[0004] However, the above technology has the following defects: first, there is the problem of selection of heating materials. Common materials that generate heat through oxidation reactions, such as iron powder, will produce solid iron oxide by-products after the reaction. The accumulation of these solids will clog the vents, causing the heating effect to decrease. Although it is recorded in the manual that a filter can be used to block the vents so that the heating material and by-products cannot penetrate the filter and enter the vents, only air can penetrate the filter. However, the filter itself will also be clogged. Therefore, how to solve the blockage of the vents is a very meaningful technical problem. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an acupuncture treatment rehabilitation auxiliary device to solve the technical problem that the vent holes of the existing acupuncture treatment devices are easily blocked during use.

[0006] Based on the above objectives, the present invention provides an acupuncture treatment rehabilitation auxiliary device, which utilizes the heat released by the oxidation reaction of the heating material to heat the acupuncture needles, comprising: a tube body, the interior of which is hollow to form a heating chamber for accommodating a heating material, a tube wall of the tube body being provided with a first vent hole, and a lower end of the tube body being open; a temperature control adjustment structure, which is used to adjust the opening size of the first vent hole; A filter screen is disposed in the tube body and can rotate axially synchronously with the tube body; A sealing plug is rotatably disposed in the opening, and the sealing plug is provided with a positioning hole for inserting the tail end of the puncture needle; A scraper, one end of which is fixed to the top of the sealing plug and the other end of which is in contact with the inner surface of the filter screen. When the tube body rotates relative to the sealing plug, the scraper can slide along the surface of the filter screen to generate a scraping force on the solid by-products attached to the inner surface of the filter screen.

[0007] As a preferred technical solution of the present invention, the temperature control and adjustment structure includes: An inner lining tube is hollow inside and has a through hole at the bottom. A second air hole corresponding to the first air hole is provided on the side wall of the inner lining tube. The outer diameter of the inner lining tube is adapted to the inner diameter of the tube body so that the inner lining tube can be axially rotated after being inserted into the tube body. The contact between the heating material and the air is controlled by aligning or staggering the second air hole and the first air hole.

[0008] As a preferred technical solution of the present invention, at least one spring piece is formed at the upper edge of the inner lining tube extending along the axial length direction, and a clamping block is formed on the inner side of the spring piece. The clamping block cooperates with a plurality of clamping grooves opened on the outer wall of the tube body. By rotating the inner lining tube, the spring piece can be driven to rotate synchronously, so that the clamping block is engaged with any one of the clamping grooves, thereby adjusting the opening size of the first vent hole.

[0009] As a preferred technical solution of the present invention, a top groove is provided at the top end of the inner liner tube, and a top cover is detachably provided in the top groove.

[0010] As a preferred technical solution of the present invention, a first groove is formed on the outer side wall of the sealing plug, and a second groove is formed on the inner side wall of the tube body at a corresponding position, and sealing rings are provided in the first groove and the second groove.

[0011] As a preferred technical solution of the present invention, the scraper is obliquely arranged at the top of the sealing plug, one end of the scraper is sharp, and a through groove is opened on the surface of the scraper. The through groove is used to reduce the contact area between the scraper and the heating material to reduce the resistance during rotation.

[0012] As a preferred technical solution of the present invention, a heat-conducting structure is rotatably provided on the upper end of the sealing plug, and an insertion space adapted to the tail end of the needle is formed inside the heat-conducting structure to isolate the needle from the heating material to avoid contamination of the needle.

[0013] As a preferred technical solution of the present invention, the heat conducting structure includes: A heat pipe with a hollow interior and an open bottom end, wherein the upper end of the heat pipe is closed; The fin has one end fixed on the outer side wall of the heat conducting pipe and the other end extending outward along the radial direction of the heat conducting pipe to increase the contact area with the heat-generating material.

[0014] As a preferred technical solution of the present invention, the bottom end of the heat-conducting tube forms a nested tube, and the nested tube is rotatably matched with the embedding groove opened at the top end of the sealing plug. The inner diameter of the positioning hole is smaller than the outer diameter of the tail end of the needle, so that the clamping force of the sealing plug on the needle is greater than the force exerted by the heat-conducting tube on the needle.

[0015] As a preferred technical solution of the present invention, the scraper is made of two metals with different thermal expansion coefficients. When the scraper is heated, it bends in a preset direction, driving the sharp part of the scraper to insert into the filter cake layer formed by solid by-products on the inside of the filter screen.

[0016] Beneficial effects of the present invention: The present invention arranges the sealing plug on the lower end opening of the tube body in a rotatable manner, and arranges a scraper at the top end of the sealing plug, so that the other end of the scraper extends along the inside of the tube body to a position in contact with the inner wall of the filter screen, especially the contact area between the filter screen and the air vent. When the filter screen is clogged with solid by-products produced by the oxidation reaction, the sealing plug can be rotated relative to the tube body to drive the scraper to slide along the surface of the filter screen to scrape off the solid by-products attached to the inner side of the filter screen and restore the permeability of the filter screen.

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, an acupuncture treatment rehabilitation auxiliary device utilizes the heat released by the oxidation reaction of the heating material to heat the needle 3, comprising: a tube body 1, the interior of which is hollow to form a heating chamber for accommodating the heating material, the tube wall of the tube body 1 being provided with a first vent 8, and the lower end of the tube body 1 being open; a temperature control adjustment structure, which is used to adjust the opening size of the first vent 8; a filter 13, which is arranged in the tube body 1 and can rotate axially synchronously with the tube body 1, and the filter 13 is used to prevent the heating material from leaking out of the tube body 1 through the first vent 8; a sealing plug 2, which is rotatably arranged in the opening, and the sealing plug 2 is provided with a positioning hole 24 for inserting the tail end of the needle 3; a scraper 14, one end of which is fixedly provided at the top end of the sealing plug 2 and the other end is kept in contact with the inner side surface of the filter 13. When the tube body 1 rotates relative to the sealing plug 2, the scraper 14 can slide along the surface of the filter 13 to generate a scraping force on solid by-products attached to the inner surface of the filter 13. The heating material is commonly found in the prior art, such as iron powder. For example, the patented technology mentioned in the background technology uses a mixture of graphite powder and iron powder. The activated carbon acts as the positive electrode of the primary battery, and the iron powder acts as the negative electrode of the primary battery. The two constitute the primary battery. The heat generated by the oxidation of the iron powder serves as the heat source for the needle 3. Vermiculite can also be added to the heating material. Vermiculite is a ferromagnesian aluminum silicate mineral that expands rapidly when heated. Vermiculite is a super thermal insulation material that can retain the heat generated by the reaction of the heating material and oxygen for a long time. The above technical solution can clear the filter 13. Since the heating material closest to the filter 13 is the first to contact the oxygen in the air, it reacts first, producing iron oxide solid by-products after the reaction. These solids accumulate and clog the inner side of the filter 13 near the first vent 8, affecting the permeability of the filter 13. As a result, the oxygen in the air cannot pass through the filter 13 through the first vent 8 and enter the tube body 1 to react with the heating material. Therefore, after the auxiliary device has been used for a period of time, it will be found that the heating effect on the needle 3 has deteriorated. At this time, maintenance is required. The medical staff holds the tube body 1 with one hand and the sealing plug 2 with the other hand. Then, the sealing plug 2 is rotated around its own axis, thereby driving the scraper 14 to slide along the surface of the filter 13 to generate a scraping force on the solid by-products attached to the inner surface of the filter 13, thereby clearing the solid by-products clogging the filter 13 and preventing the accumulation of solid by-products from causing the permeability of the filter 13 to decrease.

[0023] like Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment, the temperature control and adjustment structure includes: an inner liner tube 7 having a hollow interior and a through hole at the bottom end, a second vent hole 9 corresponding to the first vent hole 8 is formed on the side wall of the inner liner tube 7, and the outer diameter of the inner liner tube 7 is adapted to the inner diameter of the tube body 1 so that the inner liner tube 7 can rotate axially after being inserted into the tube body 1, and the contact between the heat-generating material and the air is controlled by aligning or staggering the second vent hole 9 with the first vent hole 8; The above technical solution can adjust the opening size of the first air hole 8. When in use, the inner lining tube 7 is rotated to make it rotate axially, thereby driving the second air hole 9 on the surface of the inner lining tube 7 to move relative to the first air hole 8 on the surface of the tube body 1. When the second air hole 9 is completely aligned with the first air hole 8, the first air hole 8 is fully open, and oxygen can enter the tube body 1 to the maximum extent, contact the heat-generating material and undergo an oxidation reaction, fully releasing heat from the oxidation reaction. Conversely, when the second air hole 9 is completely offset from the first air hole 8, the first air hole 8 is completely closed, oxygen cannot enter the tube body 1, and the oxidation reaction is prevented from releasing heat.

[0024] like Figure 11 and Figure 12 As shown, in this embodiment, at least one elastic piece 10 is formed at the upper end edge of the inner liner tube 7 along the axial length direction, and a clamping block 11 is formed on the inner side of the elastic piece 10. The clamping block 11 cooperates with a plurality of clamping grooves 12 provided on the outer side wall of the tube body 1. By rotating the inner liner tube 7, the elastic piece 10 can be driven to rotate synchronously, so that the clamping block 11 is engaged with any one of the clamping grooves 12, thereby adjusting the opening size of the first vent hole 8. The above technical solution can limit the rotation of the inner lining tube 7. When the inner lining tube 7 is rotated, it can drive the spring piece 10 to rotate synchronously. The spring piece 10 drives the internal block 11 to slide along the outer wall of the tube body 1. When the block 11 slides to the slot 12, under the elastic force of the spring piece 10, the block 11 is embedded in the slot 12, and a resistance to limit the axial rotation of the inner lining tube 7 is generated, thereby preventing the axial rotation of the inner lining tube 7. Of course, this limiting effect is not completely locked. Since the block 11 adopts a semi-cylindrical protrusion design, when the rotational force exceeds the elastic force of the spring piece 10 on the block 11, the inner lining tube 7 can continue to be rotated. There are multiple slots 12, which correspond to the maximum opening, complete closure and several intermediate gears of the first vent 8.

[0025] like Figure 3 and Figure 9 As shown, in this embodiment, a top groove 17 is formed at the top of the inner liner tube 7, and a top cover 16 is detachably provided in the top groove 17; The above technical solution can be used to conveniently pour out the expired heating material from the top groove 17 during maintenance, and add new heating material through the top groove 17, so that the device can be reused. Therefore, the device is not a disposable item.

[0026] like Figure 4 and Figure 6 As shown, in this embodiment, a first groove 4 is formed on the outer wall of the sealing plug 2, and a second groove 6 is formed on the inner wall of the tube body 1 at a corresponding position. A sealing ring 5 is provided in the first groove 4 and the second groove 6; The above technical solution can seal the gap between the outer wall of the sealing plug 2 and the inner wall of the tube body 1. Since the two are connected in rotation, there will be a certain gap. In order to prevent air from entering the tube body 1 through the gap and to avoid powdered heating material from leaking from the gap, it is necessary to provide a sealing ring 5 at the connection between the sealing plug 2 and the tube body 1. The gap is sealed by the expansion of the sealing ring 5, and rotation can be ensured at the same time. The sealing ring 5 is preferably a wear-resistant O-type sealing rubber ring and must have certain flame retardant properties.

[0027] like Figure 8 and Figure 14 As shown, in this embodiment, the scraper 14 is obliquely arranged at the top of the sealing plug 2, one end of the scraper 14 is sharp, and a through groove 15 is provided on the surface of the scraper 14. The scraper (14) is made of two metals with different thermal expansion coefficients, that is, the scraper 14 is a bimetallic strip, and the bimetallic strips are bonded together along the length direction, and a sharp portion is formed at one end of the bimetallic strip close to the filter screen 13; The above technical solution can reduce the contact area between the scraper 14 and the heating material to reduce the resistance during rotation. Since the heating material is provided inside the tube body 1, these powdered heating materials are in contact with the scraper 14. When the scraper 14 rotates, it will encounter greater resistance. Therefore, by tilting the scraper 14, only a smaller surface is subject to head-on resistance during rotation, which makes it convenient and effortless to rotate the scraper 14. When the scraper 14 is heated, it will bend in a preset direction, driving the sharp part of the scraper 14 to insert into the filter cake layer formed by solid by-products on the inside of the filter screen 13 to generate radial cutting force, thereby improving the cleaning effect of the filter screen 13. The two metals with different thermal expansion coefficients can be copper and iron. Generally, the acupuncture temperature is controlled between 40-50 degrees, and the inside of the tube body 1 is relatively dry. Therefore, the scraper 14 composed of the bimetallic strip oxidizes relatively slowly and has a longer service life. It should be noted that, in addition to cleaning the filter 13, the scraper 14 can also properly stir the heating material. Since the outermost heating material undergoes oxidation reaction first to produce solid by-products, such as iron oxide, as the reaction occurs, this layer of structure will become thicker and thicker, forming an iron oxide layer that prevents oxygen from contacting the heating material. This iron oxide layer is usually dense and airtight, or has very poor air permeability. It covers the surface of the unreacted internal heating material like a "shell" or "barrier". This shell prevents the diffusion of oxygen in the external air to the internal unreacted material. Therefore, the stirring of the scraper 14 can mechanically break this structure, and the fresh surface of the internal heating material that has not been fully oxidized is exposed, restoring the contact channel between oxygen and the unreacted heating material, maintaining the continuity of the oxidation heating reaction, so that oxygen can contact the innermost heating material and prevent oxygen isolation.

[0028] like Figure 3 and Figure 4 As shown, in this embodiment, a heat-conducting structure is rotatably provided on the upper end of the sealing plug 2, and an insertion space adapted to the tail end of the needle 3 is formed inside the heat-conducting structure to isolate the needle 3 from the heating material to avoid contamination of the needle 3; for details, refer to the attached Figure 7 and attached Figure 10 The heat conduction structure includes: a heat conduction pipe 19 with a hollow interior and an open bottom end, and the upper end of the heat conduction pipe 19 is closed; a fin 20, one end of which is fixed to the outer wall of the heat conduction pipe 19, and the other end extends outward in the radial direction of the heat conduction pipe 19 to increase the contact area with the heating material. The upper end of the heat conduction pipe 19 forms a cone top 21, which can facilitate the guidance of the heating material when adding the heating material, ensuring that the heating material is dispersed throughout the tube body 1; The above technical solution can prevent the needle 3 from being contaminated and minimize the reduction in thermal conductivity efficiency. Since the needle 3 does not directly contact the heating material, it can prevent the needle 3 from being contaminated. However, correspondingly, the thermal conductivity efficiency will decrease to a certain extent. By adding the fins 20, it is beneficial to increase the contact area between the heat pipe 19 and the heating material, thereby concentrating the heat to the tail of the needle 3. The heat pipe 19 and the fins 20 are preferably made of metal materials with good thermal conductivity, such as copper.

[0029] like Figure 7 、 Figure 8 and Figure 13 As shown, in this embodiment, the bottom end of the heat conducting tube 19 forms a nested tube 22, which is rotatably engaged with the embedding groove 23 provided at the top end of the sealing plug 2. The inner diameter of the positioning hole 24 is smaller than the outer diameter of the tail end of the needle 3, so that the clamping force of the sealing plug 2 on the needle 3 is greater than the force exerted by the heat conducting tube 19 on the needle 3. The above technical solution can avoid the large area of ​​the fins 20, which will cause the sealing plug 2 to encounter excessive resistance when rotating. Therefore, by arranging the heat pipe 19 on the sealing plug 2 in a rotatable manner, when the sealing plug 2 is rotated, the heat pipe 19 will not be driven to rotate. The fins 20 and the heat pipe 19 can remain stationary, and the sealing plug 2 can rotate freely, which is more labor-saving. A recessed groove 18 is provided on the side of the sealing plug 2 to form a concave-convex structure, which is convenient for grasping the rotation.

[0030] Working principle: When in use, open the top cover 16, add the heating material into the tube body 1 through the top groove 17, cover the top cover 16, insert the tail end of the needle 3 into the tube body 1 through the positioning hole 24 of the sealing plug 2, until the tail end of the needle 3 enters the heat conducting tube 19, rotate the inner lining tube 7 so that its second vent 9 moves relative to the first vent 8 on the surface of the tube body 1, when the second vent 9 partially overlaps with the first vent 8, the air inlet channel is opened, oxygen comes into contact with the heating material, and an oxidation reaction occurs. Heat is transferred to the tail end of the needle 3 through the fins 20 and the heat conducting tube 19, and then the heat is transferred to the needle body of the needle 3 through the tail end. After the needle 3 is inserted into the corresponding part of the patient, the patient can be treated. After the treatment is completed, the needle 3 is pulled out; After the auxiliary device has been used for a period of time, the heating material closest to the filter 13 is the first to come into contact with oxygen in the air, and thus reacts first, producing solid iron oxide by-products after the reaction. These solids accumulate and clog the inner side of the filter 13 and the area near the first vent 8, affecting the permeability of the filter 13, causing the oxygen in the air to be unable to pass through the filter 13 through the first vent 8 and enter the tube body 1, where it comes into contact with the heating material and reacts, resulting in a deterioration in the heating effect on the needle 3. At this time, maintenance is required. The medical staff holds the tube body 1 with one hand and the sealing plug 2 with the other hand, and then rotates the sealing plug 2 around its own axis, thereby driving the scraper 14 to slide along the surface of the filter 13 to generate a scraping force on the solid by-products attached to the inner surface of the filter 13, thereby cleaning up the solid by-products that clog the filter 13 and preventing the accumulation of solid by-products from causing a decrease in the permeability of the filter 13. In addition to the solid by-products attached to the surface of the filter 13, there are also solid by-products inside the heating material, such as an iron oxide layer. As the reaction occurs, this layer of structure will become thicker and thicker. This iron oxide layer is usually dense and airtight. This shell hinders the diffusion of oxygen in the external air to the unreacted material inside. Therefore, the stirring of the scraper 14 can also mechanically break this layer of structure, so that the fresh surface of the heating material inside that has not been completely oxidized is exposed, and the contact channel between oxygen and the unreacted heating material is restored.
