Description

Technical Field

[0001] This utility model relates to the field of scraping auxiliary components, specifically to a scraping device for internal medicine in traditional Chinese medicine. Background Technology

[0002] Gua sha in traditional Chinese medicine internal medicine is guided by the theory of meridians and acupoints in traditional Chinese medicine. It involves using gua sha tools and corresponding techniques, applying a certain medium, and repeatedly scraping and rubbing the skin to cause local skin changes such as red millet-like spots or dark red bleeding points, thereby achieving the effect of promoting blood circulation and removing sha.

[0003] Specifically, in the scraping operation, not only is a scraping board needed, but essential oil also needs to be applied to the skin surface during the scraping process. Moreover, the operation of applying essential oil and the scraping operation need to be repeated throughout the scraping process. However, in the current technology, since the scraping tool and the tool for applying essential oil are usually separate and independent, the operator needs to constantly pick up and put down the tool to repeat the operation of applying essential oil and scraping. This not only prolongs the scraping process, but is also not very convenient to use. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-8As shown, this utility model provides a traditional Chinese medicine internal medicine scraping device, including a base plate 2, a scraping board body 3, and an syringe body 5. The scraping board body 3, which is used to perform scraping operations by contacting the skin, can be detachably assembled on the front bottom of the base plate 2 via a disassembly and assembly assembly 4. The scraping board body 3 is arranged vertically along the horizontal direction. Specifically, the disassembly and assembly assembly 4 includes a U-shaped bracket 401 and a locking rod 404. The U-shaped bracket 401 is fixed vertically along the horizontal direction on the front bottom of the base plate 2, and the top of the scraping board is locked by the U-shaped bracket 401 in a vertical sliding engagement manner. Locking holes 405 are provided on both sides of the top front of the scraping board along the longitudinal direction, and mating holes 403 are provided on both sides of the front front of the U-shaped bracket 401 along the longitudinal direction. The 03 and locking hole 405 are longitudinally coaxially aligned. At the same time, each set of coaxially aligned mating holes 403 and locking holes 405 are coaxially and detachably inserted with locking rods 404. The purpose of this arrangement is that by using the U-shaped card holder 401 of the disassembly and assembly assembly 4 to lock the top of the scraping board body 3 in a vertical sliding engagement, and by using the locking rods 404 to sequentially engage with the mating holes 403 and locking holes 405 in a coaxial manner, the scraping board body 3 can be detachably assembled on the front of the bottom of the substrate 2. It is only necessary to release the locking rods 404 sequentially from the locking holes 405 and mating holes 403 to remove the scraping board body 3 from the front of the bottom of the substrate 2. The assembly and disassembly of the scraping board body 3 on the front of the bottom of the substrate 2 is simple and easy to implement.

[0034] See Figures 1-6 As shown, a syringe body 5 for replenishing essential oil is detachably assembled to the rear top surface of the substrate 2 via a syringe holder 7. The axis of the syringe body 5 is arranged laterally. Specifically, the syringe holder 7 includes a sleeve 703 and a clamping stud 702. The sleeve 703 is assembled and fixed to the rear top surface of the substrate 2 via a connecting seat 704 at the bottom periphery. Both ends of the sleeve 703 are open, and the syringe barrel of the syringe body 5 passes coaxially through the sleeve 703 in a laterally sliding fit. The top of the sleeve 703 has a vertically arranged mounting hole 705 in the radial direction. The mounting hole 705 is a through hole, and a clamping stud is coaxially inserted into the mounting hole 705 in a threaded fit. The bottom end of the stud 702 is coaxially fixed with an elastic pressure block 706 whose outer diameter is smaller than that of the mounting hole 705. The purpose of this arrangement is that the syringe body 5 can be detachably fixed to the rear of the top surface of the substrate 2 by means of axial sliding engagement between the syringe barrel and the sleeve 703 and by tightening the stud 702 to press the elastic pressure block 706 against the outside of the syringe barrel of the syringe body 5. Only by loosening the stud 702 can the syringe barrel of the syringe body 5 be axially slid out of the sleeve 703 and removed from the rear of the top surface of the substrate 2. The assembly and disassembly of the syringe body 5 on the rear of the top surface of the substrate 2 is simple and easy to implement.

[0035] See Figures 1-8As shown, an essential oil dispersing component 6 for dispersing essential oils onto the skin surface is assembled and installed on the rear bottom surface of the substrate 2. The essential oil dispersing component 6 is connected to the dispensing tube 501 of the syringe body 5. Specifically, the essential oil dispersing component 6 includes a dispensing tube 602 and a connecting hose 601. The dispensing tube 602 is horizontally positioned below the rear bottom surface of the substrate 2. Multiple drip holes 604 are vertically opened on the bottom surface of the dispensing tube 602. Both ends of the dispensing tube 602 are assembled and installed on the rear bottom surface of the substrate 2 through a clamp 603. One end of the dispensing tube 602 is closed, and the other end of the dispensing tube 602 is open and connected to the connecting hose 601. The syringe body 5 is connected to the dispensing tube 501. The reason for this design is that after the syringe body 5 has finished drawing in the essential oil, it is coaxially fixed by the syringe barrel fixing part 7. The dispensing tube 501 of the syringe body 5 is connected to the dispensing tube 602 through the connecting hose 601. This allows the syringe body 5 to squeeze the essential oil into the dispensing tube 602 through the connecting hose 601. Then, the essential oil is infused through the dispensing tube 602 and discharged through multiple drip holes 604, so that it can fall on the skin surface for rapid replenishment of essential oil. In addition, since the syringe body 5 has the function of quantitative liquid aspiration and discharge, it can also avoid wasting essential oil to a certain extent.

[0036] See Figures 1-8 As shown, the following optimizations were made to the base plate 2, the disassembly assembly 4, and the syringe fixing component 7. Specifically, for the base plate 2, both sides of the front front of the top surface of the base plate 2 are vertically fixed with a grip plate 1, and the top of each grip plate 1 has a grip groove 101 for easy hand gripping, so that medical personnel can hold the base plate 2 stably by gripping the grip groove 101 with both hands and perform scraping operation with the scraping board body 3. Specifically, for the disassembly assembly 4, the front end of the locking rod 404 extending out of the mating hole 403 is coaxially fixed with a handle 402 for easy gripping, so that the locking rod 404 can be quickly assembled and disassembled with the mating hole 403 and the locking hole 405 by applying force with the handle 402. Optionally, both the mating hole 403 and the locking hole 405 are threaded through holes, and the locking rods 404 are all screws. The locking rods 404 are coaxially and detachably connected to the mating holes 403 and 405 via threaded engagement. This configuration allows for quick assembly and disassembly of the locking rods 404 and 405 by screwing. Alternatively, both the mating hole 403 and the locking hole 405 are circular through holes, and the locking rods 404 are all rubber cylindrical rods. The locking rods 404 are coaxially and detachably connected to the mating holes 403 and 405 via tension engagement. This configuration allows for quick assembly and disassembly of the locking rods 404 and 404 via axial pressure and pulling. Specifically, the top end of the clamping stud 702 is coaxially fixed with an end 701 so that the clamping stud 702 can be screwed by applying force by holding the end 701.

[0037] With the above structure, specifically when used in Gua Sha (scraping therapy) in Traditional Chinese Medicine internal medicine, the Gua Sha board body 3 is detachably assembled at the front of the base plate 2 via the disassembly and assembly assembly 4. Simultaneously, an essential oil dispersing component 6 and an essential oil replenishing syringe body 5 are assembled at the rear of the base plate 2. Furthermore, the liquid outlet tube 501 of the syringe body 5 is connected to the liquid distribution tube 602 of the essential oil dispersing component 6 via a connecting hose 601. This integrates the Gua Sha function and the essential oil replenishment function, facilitating the operator's use during Gua Sha. Repeatedly applying essential oil and performing gua sha (scraping) helps improve gua sha efficiency and ease of use. Specifically, regarding the assembly 4, the U-shaped bracket 401 of the assembly 4 vertically slides and engages with the top of the gua sha board body 3. The locking rod 404 then coaxially engages with the mating hole 403 and the locking hole 405, allowing the gua sha board body 3 to be detachably assembled onto the front bottom of the base plate 2. This is achieved simply by disengaging the locking rod 404 from the locking hole 405 and the mating hole 403. The scraping board body 3 is detached from the front of the bottom of the base plate 2. The assembly and disassembly of the scraping board body 3 on the front of the bottom of the base plate 2 is simple and easy to implement. It is convenient to assemble the scraping board body 3 on the front of the bottom of the base plate 2 for scraping operation, and it is also convenient to disassemble the scraping board body 3 for cleaning and maintenance later. As for the syringe barrel fixing part 7, the syringe barrel of the syringe body 5 and the sleeve 703 slide axially and the elastic pressure block 706 is pressed against the outside of the syringe barrel of the syringe body 5 by tightening the clamping stud 702. The enclosed design allows the syringe body 5 to be detachably fixed to the rear top surface of the substrate 2. By simply loosening the clamping stud 702, the syringe barrel of the syringe body 5 can be axially slid out of the sleeve 703 and removed from the rear top surface of the substrate 2. The assembly and disassembly of the syringe body 5 on the rear top surface of the substrate 2 is simple and easy to implement. It is convenient to assemble the syringe body 5 on the rear top of the substrate 2 for essential oil replenishment, and it is also convenient to disassemble the syringe body 5 for subsequent essential oil aspiration replenishment and cleaning and maintenance.
