Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a dermatological aid for the care of paronychia. Background Technology

[0002] Paronychia is a common dermatological infectious disease, mainly an inflammatory reaction of the nail groove and surrounding tissues caused by factors such as minor trauma, ingrown nails, and bacterial infection. It often manifests as redness, swelling, pain, and suppuration in the nail groove area. In mild cases, there may only be slight local inflammation. As the inflammation worsens, pus will gradually accumulate. If not treated in time, the infection may spread, causing more serious damage to the periungual tissues and even affecting limb movement and daily life.

[0003] The core of paronychia treatment lies in timely relieving inflammation, clearing pus, preventing the infection from worsening, and creating conditions for normal nail growth. In clinical and daily home care, it's necessary to widen the narrow nail groove to increase the operating space, facilitating the cleaning of pus and the implementation of subsequent treatment measures. Furthermore, due to individual differences in nail size, nail groove width, and the extent of the lesion, different application scenarios need to be considered to ensure the targeted and effective nature of the care procedures. In addition, timely cleaning of pus is crucial to preventing the spread of infection; this requires efficient removal of pus while widening the nail groove to reduce residual irritation.

[0004] Currently, most nursing tools for paronychia are designed for a single function, which makes it difficult to simultaneously meet the core requirements of opening the nail groove, accurately cleaning pus, and adapting to the needs of different patients. In existing technologies, some tools can only open the nail groove, and pus cleaning needs to be done separately with the help of other instruments. The operation steps are cumbersome, and the gap between the nail grooves is easy to close after opening, resulting in pus residue and affecting the treatment effect. Summary of the Invention

[0005] In view of the problems in the existing technology, some tools can only open the nail groove, and the cleaning of pus needs to be completed separately with the help of other instruments. The operation steps are cumbersome, and the gap between the nail groove is easy to close after opening, resulting in pus residue and affecting the treatment effect. The purpose of this invention is to provide a dermatological auxiliary tool for the care of paronychia.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A dermatological auxiliary tool for paronychia care includes a frame, on which a stretching component is provided. The stretching component is used to match and stretch the patient's nail groove to assist in treatment.

[0008] The spreading assembly includes a main nail plate, which is connected to a pre-suction assembly. The pre-suction assembly is used to suction and clean the pus during the spreading process.

[0009] An adjustment component is disposed on the main armor plate and is used to adjust the support range of the main armor plate.

[0010] Optionally, the spreading assembly further includes a pair of curved spreading frames rotatably mounted on the frame, with an elastic strip installed on the curved spreading frames. A main armor plate is connected to the curved spreading frames via an adaptive connecting assembly. A pull cylinder is fixedly mounted on the frame, and a pull rod controlled by a drive component is slidably mounted inside the pull cylinder. An adjusting frame is fixedly mounted on the pull rod, and a pair of rollers are rotatably mounted on the adjusting frame, with the rollers abutting against the curved spreading frames.

[0011] Optionally, the driving component is an electric telescopic rod, and the pull tube is provided with a switch electrically connected to the electric telescopic rod.

[0012] Optionally, the adaptive connection assembly includes a pivot rotatably mounted on a curved support frame, and the main armor plate is detachably mounted on the pivot.

[0013] Optionally, the curved support frame has a movable groove, a first movable shaft is slidably installed in the movable groove, a cover plate is fixedly installed on the first movable shaft, a limiting protrusion is fixedly installed on the cover plate, a limiting groove that cooperates with the limiting protrusion is opened on the rotating shaft, a second movable shaft is fixedly installed on the cover plate, and the second movable shaft is slidably connected to the inner wall of the limiting groove.

[0014] Optionally, the pre-suction assembly includes suction holes formed in the main armor plate, with multiple suction holes arranged at different angles. The main armor plate has an integrated hole communicating with the suction holes. A connecting pipe communicating with the integrated hole is fixedly installed on the main armor plate. A piston is fixedly installed on the pull rod. When the piston moves, negative pressure can be generated inside the pull tube. A connecting pipe communicating with the inside of the pull tube is fixedly installed on the pull tube. The end of the connecting pipe away from the main armor plate is connected to the connecting pipe through a locking assembly. A collection bag is provided on the connecting pipe.

[0015] Optionally, a sealing block is slidably installed inside the integrated hole, and a spring is fixedly installed on the sealing block. The other end of the spring is fixedly connected to the inner wall of the integrated hole. An expansion cavity is opened inside the integrated hole, and the diameter of the expansion cavity is larger than that of the sealing block.

[0016] Optionally, the positioning assembly includes a positioning block fixedly installed on the connecting pipe, an installation block fixedly installed on the connecting pipe, a rotating locking rod rotatably installed on the installation block to cooperate with the positioning block, a spring piece fixedly installed on the rotating locking rod, and the end of the spring piece away from the rotating locking rod being fixedly connected to the connecting pipe.

[0017] Optionally, the adjustment assembly includes a pair of secondary armor plates that are slidably mounted within the main armor plate.

[0018] Optionally, a rack is fixedly mounted on the secondary armor plate, and an adjusting gear that meshes with the rack is rotatably mounted on the main armor plate, with a turntable fixedly mounted on the adjusting gear.

[0019] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0020] In the above scheme, a spreading component is set up. The core of the spreading component is a pair of curved spreading frames that are rotatably mounted on the frame. The elastic strip on the curved spreading frame provides a restoring elastic force to ensure that the spreading action is smooth and recoverable. The curved spreading frame is connected to the main armor plate through an adaptive connection component, so that the main armor plate can adjust its angle synchronously with the rotation of the curved spreading frame to better fit the contour of the nail groove. The pull cylinder on the frame provides a sliding guide for the pull rod. The drive component controls the pull rod to move along the axial direction in the pull cylinder. The pull rod drives the adjustment frame to move synchronously. A pair of rollers on the adjustment frame abut against the curved spreading frame. As the adjustment frame moves, the rollers generate a lateral thrust on the curved spreading frame, forcing the curved spreading frame to rotate around the mounting point on the frame and move closer to each other. When the main armor plate is inserted into the nail groove, it drives the pull rod in the opposite direction. The elastic force of the elastic strip drives the curved spreading frame and the main armor plate to move to realize the nail groove spreading action. The spreading force is uniform and controllable.

[0021] By setting up adaptive connection components, the main nail plate can adjust its angle around the pivot point, ensuring that the main nail plate always conforms to the skin contour around the nail groove. This adapts to the nail groove structure of different patients, achieving adaptive angle adjustment of the main nail plate, improving fit, and ensuring the stretching and suction effects. At the same time, the detachable design of the main nail plate facilitates replacement, cleaning, disinfection, and maintenance. Attached Figure Description

[0045] like Figures 1 to 8As shown, this embodiment of the invention provides a dermatological auxiliary tool for paronychia care, including a frame 10, on which a spreading component 20 is provided. The spreading component 20 is used to match the patient's nail groove and spread it to assist in treatment.

[0046] The spreading component 20 includes a main armor plate 22, which is connected to a pre-suction component 40. The pre-suction component 40 is used to suction and clean the pus during the spreading process.

[0047] Adjustment component 60, which is disposed on the main armor plate 22, is used to adjust the support range of the main armor plate 22;

[0048] The frame 10 serves as the overall support base. After the expansion component 20 is precisely matched with the patient's nail groove, the mechanical structure generates force to open the narrow nail groove gap, expand the treatment operation space, avoid the surrounding tissue of the nail groove from squeezing the wound, and create conditions for subsequent pus cleaning and treatment.

[0049] The pre-aspiration component 40 is activated at the same time as the opening component 20 to aspirate the pus in the nail groove, so that opening and cleaning are carried out simultaneously, reducing the irritation of the wound by residual pus.

[0050] The adjustment component 60 can flexibly adjust the support range of the main nail plate 22 according to individual differences such as the patient's nail size and nail groove width, ensuring that the expansion component 20 can adapt to the usage needs of different patients and improve the versatility and fit of the device.

[0051] The expansion assembly 20 also includes a pair of curved expansion frames 21 rotatably mounted on the frame 10. An elastic strip 26 is installed on the curved expansion frames 21. A main armor plate 22 is connected to the curved expansion frame 21 through an adaptive connection assembly 30. A pull cylinder 28 is fixedly mounted on the frame 10. A pull rod 23 controlled by a drive component 27 is slidably mounted inside the pull cylinder 28. An adjustment frame 24 is fixedly mounted on the pull rod 23. A pair of rollers 25 are rotatably mounted on the adjustment frame 24. The rollers 25 abut against the curved expansion frames 21.

[0052] The core of the spreading assembly 20 is a pair of curved spreading frames 21 rotatably mounted on the frame 10. Elastic strips 26 on the curved spreading frames 21 provide a restoring force, ensuring a smooth and recoverable spreading action. The curved spreading frames 21 are connected to the main armor plate 22 via an adaptive connection assembly 30, allowing the main armor plate 22 to adjust its angle synchronously with the rotation of the curved spreading frames 21, better conforming to the contour of the nail groove. A pull cylinder 28 on the frame 10 provides a sliding guide for the pull rod 23, and a drive component 27 controls the pull rod 23's movement within the pull cylinder. The inner part moves along the axial direction, and the pull rod 23 drives the adjustment frame 24 to move synchronously. A pair of rollers 25 on the adjustment frame 24 abut against the curved support frame 21. As the adjustment frame 24 moves, the rollers 25 generate a lateral thrust on the curved support frame 21, forcing the curved support frame 21 to rotate around the mounting point on the frame 10 and move closer to each other. When the main armor plate 22 is inserted into the armor groove, it drives the pull rod 23 in the opposite direction. The elasticity of the elastic strip 26 drives the curved support frame 21 and the main armor plate 22 to move to realize the armor groove opening action. The opening force is uniform and controllable.

[0053] The driving component 27 is an electric telescopic rod, and the pull tube 28 is equipped with a switch that is electrically connected to the electric telescopic rod;

[0054] When the switch is pressed, the electric telescopic rod is powered on and generates a linear driving force, pushing the pull rod 23 to slide within the pull cylinder 28. When the switch is pressed again, the electric telescopic rod resets, and the pull rod 23 moves back synchronously with the telescopic rod under the reset force of the elastic strip 26. The extension and retraction stroke of the electric telescopic rod is precisely controllable, and the moving distance of the pull rod 23 can be adjusted according to the treatment needs, thereby controlling the rotation angle of the curved support frame 21 and the degree of nail groove opening. Compared with manual drive, the electric telescopic rod provides a more stable driving force, and the opening force and stroke can be precisely controlled, reducing human operation errors.

[0055] The adaptive connection assembly 30 includes a rotating shaft 31 rotatably mounted on a curved support frame 21, and the main armor plate 22 is detachably mounted on the rotating shaft 31;

[0056] The main nail plate 22 can adjust its angle around the pivot 31, so that the main nail plate 22 can always fit the skin contour around the nail groove, adapt to the nail groove structure of different patients, realize the adaptive adjustment of the angle of the main nail plate 22, improve the fit, and ensure the opening and suction effect. At the same time, the detachable design of the main nail plate 22 makes it easy to replace the main nail plate 22 and facilitates the cleaning, disinfection and replacement maintenance of the main nail plate 22.

[0057] The curved support frame 21 has a movable groove 36, a first movable shaft 32 is slidably installed in the movable groove 36, a cover plate 33 is fixedly installed on the first movable shaft 32, a limiting protrusion 35 is fixedly installed on the cover plate 33, a limiting groove 34 is opened on the rotating shaft 31 to cooperate with the limiting protrusion 35, a second movable shaft 37 is fixedly installed on the cover plate 33, and the second movable shaft 37 is slidably connected to the inner wall of the limiting groove 34;

[0058] The movable groove 36 on the curved support frame 21 provides sliding space for the first movable shaft 32. The first movable shaft 32 is fixedly connected to the cover plate 33, allowing the cover plate 33 to move along the movable groove 36. The limiting protrusion 35 on the cover plate 33 cooperates with the limiting groove 34 on the rotating shaft 31. After the main armor plate 22 is installed, the cover plate 33 is moved to make the limiting protrusion 35 embed into the limiting groove 34, thereby fixing the angle of the main armor plate 22. Moving the cover plate 33 in the opposite direction will disengage the limiting protrusion 35 from the limiting groove 34, at which point the angle of the main armor plate 22 can be freely adjusted. The second movable shaft 37 on the cover plate 33 is slidably connected to the inner wall of the limiting groove 34, providing guidance and support for the movement of the cover plate 33, ensuring that the cooperation between the limiting protrusion 35 and the limiting groove 34 is precise and stable, preventing the main armor plate 22 from loosening or shifting after installation, and enabling quick fixing and release of the angle of the main armor plate 22, making operation convenient.

[0059] The pre-suction assembly 40 includes suction holes 41 formed in the main armor plate 22. Multiple suction holes 41 are provided and arranged at different angles. An integrated hole 42 communicating with the suction holes 41 is formed in the main armor plate 22. A connecting pipe 43 communicating with the integrated hole 42 is fixedly installed on the main armor plate 22. A piston 45 is fixedly installed on the pull rod 23. When the piston 45 moves, negative pressure can be generated in the pull cylinder 28. A connecting pipe 46 communicating with the inside of the pull cylinder 28 is fixedly installed on the pull cylinder 28. The end of the connecting pipe 43 away from the main armor plate 22 is connected to the connecting pipe 46 through a locking assembly 50. A collection bag 44 is provided on the connecting pipe 43.

[0060] The core of the pre-aspiration component 40 consists of multiple aspiration holes 41 at different angles within the main nail plate 22. These multiple holes at various angles cover different areas of the nail groove, ensuring thorough aspiration of pus. An integrated hole 42 within the main nail plate 22 connects all the aspiration holes 41, allowing the pus drawn in by the multiple holes 41 to be concentrated within the integrated hole 42. A connecting tube 43 on the main nail plate 22 connects to the integrated hole 42, and the connecting tube 43 is fixedly connected to the connecting tube 46 on the pull tube 28 via a locking component 50. A complete suction channel is formed. The piston 45 on the pull rod 23 slides inside the pull tube 28 with the pull rod 23. When the pull rod 23 is pulled outward, the piston 45 creates a negative pressure environment inside the pull tube 28. This negative pressure is transmitted to the integration hole 42 through the connecting tube 46 and the connecting tube 43, and then distributed to each suction hole 41. This generates an adsorption force to draw in the pus from the nail groove. The collection sac 44 on the connecting tube 43 is used to store the suctioned pus. This multi-angle suction hole 41 increases the coverage of pus and makes suction more thorough.

[0061] A sealing block 47 is slidably installed inside the integrated hole 42, and a spring 48 is fixedly installed on the sealing block 47. The other end of the spring 48 is fixedly connected to the inner wall of the integrated hole 42. An expansion cavity 49 is opened inside the integrated hole 42, and the diameter of the expansion cavity 49 is larger than that of the sealing block 47.

[0062] The sealing block 47, which is slidably installed inside the integrated hole 42, cooperates with the spring 48. The spring 48 always applies an elastic tension to the sealing block 47, so that the sealing block 47 is normally in contact with the inner wall of the integrated hole 42, ensuring the sealing of the integrated hole 42. When a negative pressure is generated inside the pull tube 28, the negative pressure force overcomes the elastic force of the spring 48 and pushes the sealing block 47 towards the expansion cavity 49. The channel inside the integrated hole 42 is opened, and the pus flows smoothly through the suction hole 41 and the integrated hole 42 into the connecting tube 43. When suction stops, the spring 48 resets and pushes the sealing block 47 back to the initial position, resealing the integrated hole 42. The diameter of the expansion cavity 49 is larger than that of the sealing block 47 to ensure the flow cross-sectional area when the channel is open, without affecting the efficiency of pus suction. The cooperation between the sealing block 47 and the spring 48 realizes the automatic sealing of the integrated hole 42, preventing the pus from flowing back to the wound surface and causing secondary infection when suction stops.

[0063] The locking assembly 50 includes a locking block 51 fixedly installed on the connecting pipe 46, an installation block 52 fixedly installed on the connecting pipe 43, a rotating locking rod 53 that cooperates with the locking block 51 rotatably installed on the installation block 52, a spring piece 54 fixedly installed on the rotating locking rod 53, and one end of the spring piece 54 away from the rotating locking rod 53 is fixedly connected to the connecting pipe 43.

[0064] The locking block 51 of the locking assembly 50 is fixed to the connecting pipe 46. The mounting block 52 on the connecting pipe 43 provides mounting support for the rotating locking rod 53. The rotating locking rod 53 can rotate around the mounting block 52. The spring piece 54 applies an elastic force to the rotating locking rod 53, so that the rotating locking rod 53 tends to be in contact with the locking block 51 under normal conditions. When the connecting pipe 43 is connected to the connecting pipe 46, rotating the rotating locking rod 53 causes the rotating locking rod 53 to engage with the locking block 51. The elastic force of the spring piece 54 will rotate the locking rod 53. The clamping rod 53 presses down to fix the connecting pipe 43 and the connecting pipe 46. When disassembling, the clamping rod 53 is rotated in the opposite direction to overcome the elastic force of the spring piece 54 and disengage the clamping rod 53 from the locking block 51, thus separating the connecting pipe 43 and the connecting pipe 46. This allows for quick assembly and disassembly of the connecting pipe 43 and the connecting pipe 46, facilitating the assembly, cleaning and maintenance of the device. The clamping action of the spring piece 54 ensures a firm connection and prevents the connection from falling off due to negative pressure or movement during the suction process, thus ensuring the sealing of the suction channel.

[0065] The adjustment component 60 includes a pair of secondary armor plates 61 that are slidably installed within the main armor plate 22. The secondary armor plates 61 are provided in a pair and are symmetrically arranged.

[0066] A pair of secondary nail plates 61 of the adjusting component 60 are symmetrically slidably installed inside the main nail plate 22. The secondary nail plates 61 can slide along the length of the main nail plate 22, thereby adjusting the effective support range of the entire nail plate (main nail plate 22 + secondary nail plate 61). Depending on the length and width of the patient's nail and the size of the lesion area in the nail groove, the sliding secondary nail plates 61 extend or retract from the main nail plate 22 so that the nail plate can completely cover the lesion area, ensuring that the stretching and suction effects are accurately applied to the target area. The sliding design of the secondary nail plates 61 allows the nail plate support range to be flexibly adjusted to adapt to different nail sizes and different lesion areas, improving the versatility of the device.

[0067] A rack 62 is fixedly installed on the secondary armor plate 61, and an adjusting gear 63 that meshes with the rack 62 is rotatably installed on the main armor plate 22. A turntable 64 is fixedly installed on the adjusting gear 63.

[0068] The rack 62 on the secondary armor plate 61 meshes with the adjusting gear 63 on the main armor plate 22. The turntable 64 on the adjusting gear 63 facilitates rotation by medical staff or patients. When the turntable 64 is rotated, it drives the adjusting gear 63 to rotate synchronously. The rotational motion of the gear is converted into the linear sliding motion of the secondary armor plate 61 through the rack 62. When the turntable 64 is rotated, the secondary armor plate 61 extends out of the main armor plate 22, expanding the support range. When the turntable 64 is rotated in the opposite direction, the secondary armor plate 61 retracts into the main armor plate 22, reducing the support range. The precise adjustment of the secondary armor plate 61 is achieved through the gear and rack 62 transmission, resulting in more accurate control of the support range.

[0069] The specific workflow of the technical solution provided by this invention is as follows:

[0070] Device preparation: Based on the patient's nail size and lesion condition, adjust the support range by adjusting component 60, rotate turntable 64 to drive adjustment gear 63 to rotate, gear meshes with rack 62 on sub-nail plate 61, drive sub-nail plate 61 to slide along main nail plate 22 until the nail plate structure composed of main nail plate 22 and sub-nail plate 61 is adapted to the patient's nail size.

[0071] The adjusted main armor plate 22 is installed on the rotating shaft 31 of the curved support frame 21 by the adaptive connection component 30. The moving cover plate 33 causes the limiting protrusion 35 to be embedded in the limiting groove 34 of the rotating shaft 31. The second movable shaft 37 slides along the inner wall of the limiting groove 34 to guide and complete the fixing of the angle of the main armor plate 22.

[0072] Press the switch on the pull tube 28 to start the drive component 27. The drive rod 23 slides inside the pull tube 28. The pull rod 23 drives the adjustment frame 24 to move. The roller 25 on the adjustment frame 24 generates a lateral thrust on the curved support frame 21, forcing the curved support frame 21 to rotate around the mounting point on the frame 10. The main armor plate 22 rotates with the curved support frame 21 to open the gap in the armor groove until a suitable operating space is reached.

[0073] During the sliding process of the pull rod 23, the piston 45 at its end creates a negative pressure in the pull tube 28. The negative pressure is transmitted to the integration hole 42 of the main nail plate 22 through the connecting pipe 46 and the connecting pipe 43 (connected by the locking assembly 50, the rotating locking rod 53 engages with the locking block 51, and the spring piece 54 ensures a seal). The negative pressure overcomes the elastic force of the spring 48 and pushes the sealing block 47 to move towards the expansion cavity 49. The channel of the integration hole 42 opens, and the suction holes 41 at multiple angles on the main nail plate 22 generate suction force, drawing in the pus from the nail groove. The pus is then collected in the collection sac 44 through the integration hole 42 and the connecting pipe 43 for storage.

[0074] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
