Abstract
Description
Technical Field
[0001] This invention relates to consumer goods, particularly medical devices, and especially to a device for preventing skin and clothing from coming into contact. Background Technology
[0002] For certain types of skin lesions, such as the acute phase of shingles, postherpetic neuralgia, burns, and skin pustules, it is crucial to avoid contact between clothing and the affected area during treatment to prevent further aggravation and impaired healing. For patients with postherpetic neuralgia or postherpetic recurrent pain, friction between the skin and clothing can cause contact-induced pain and hyperalgesia, leading to limited mobility and impacting quality of life. Existing devices to prevent skin contact with clothing are generally large, designed for bedside or surface placement, and not portable. Other devices are designed for shingles patients, but their application is limited by the inability to flexibly adjust to the affected area. Summary of the Invention
[0003] The purpose of this invention is to provide a skin-clothing contact prevention device that solves the technical problems of existing skin-clothing contact prevention devices being large in size, poor in portability, and unable to be flexibly adjusted.
[0004] This invention discloses a skin-and-clothing contact-prevention device, comprising a first retractable main rod and a second retractable main rod arranged parallel to each other. Each of the first and second retractable main rods includes a first retractable end and a second retractable end. A telescopic locking mechanism is provided between the second retractable end and the first retractable end. The first and second retractable main rods are connected by an extension-contraction structure. A support structure is provided at the bottom of each of the first and second retractable ends, and an adhesive structure is provided at the bottom of each support structure. A rotating support and fixing structure is provided at the top of each of the first and second retractable ends. Each rotating support and fixing structure includes a fixing tube and a rotating rod. The fixing tube is fixedly connected to its corresponding first or second retractable end. A circumferential rotating joint and an axial limiting structure are provided between the lower end of the rotating rod and the fixing tube. At least four claw-shaped structures are distributed circumferentially along the upper end of the rotating rod, and at least four fine tooth-shaped protrusions are provided on the upper surface of each claw-shaped structure.
[0005] Furthermore, the extension and retraction structure includes a first linkage mechanism and a second linkage mechanism. Each linkage mechanism includes a first pivot and a second pivot. The first and second pivots of the first linkage mechanism are respectively connected to the first telescopic end of the first telescopic main rod and the first telescopic end of the second telescopic main rod. The first and second pivots of the second linkage mechanism are respectively connected to the second telescopic ends of the first and second telescopic main rods. The first pivot is hinged to one end of a first link, the other end of the first link is hinged to one end of a second link via a third pivot, and the other end of the second link is hinged to the third link via a fourth pivot. One end of the first linkage is hinged, and the other end of the third linkage is hinged to one end of the fourth linkage via a fifth pivot. The other end of the fourth linkage is hinged to one end of the fifth linkage via a sixth pivot. The other end of the fifth linkage is hinged to one end of the sixth linkage via a seventh pivot. The other end of the sixth linkage is hinged to the second pivot. The fourth pivot of the first linkage mechanism is connected to the fourth pivot of the second linkage mechanism via a seventh linkage. The sixth pivot of the first linkage mechanism is connected to the sixth pivot of the second linkage mechanism via an eighth linkage. Each of the first, second, third, fourth, fifth, sixth, and seventh pivots is equipped with a damping structure.
[0006] Furthermore, a pivot angle locking mechanism is provided between the first link and the second link, between the second link and the third link, between the third link and the fourth link, between the fourth link and the fifth link, and between the fifth link and the sixth link.
[0007] Furthermore, the support structure includes a support plate and a telescopic rod. The upper end of the telescopic rod is connected to the first telescopic main rod, and the lower end of the telescopic rod is connected to the support plate through a shock-absorbing spring. The adhesive structure is set on the bottom surface of the support plate.
[0008] Furthermore, each of the first and second telescopic main rods has an eighth rotating shaft in the side wall facing each other. The eighth rotating shaft, together with the first and second telescopic main rods, forms a circumferential rotating pair. The two ends of the extension and retraction structure are respectively connected to the eighth rotating shaft.
[0009] Compared with existing technologies, the effects of this invention are positive and significant. The support structure is adhered to the surface of normal human skin using an adhesive structure, and the rotating support and fixing structure fits snugly against clothing. The fine tooth-like protrusions increase friction with the clothing. The unfolded length of the stretchable and contractile structure is adjusted according to the area of the patient's skin injury, thereby adjusting the distance between the first and second retractable main rods, allowing for flexible adjustment of the support area to accommodate different skin injury areas. This invention is lightweight and portable, and can be used simply by adhering it to the skin. By setting four rotating support and fixing structures and a support structure, the unfolded stretchable and contractile structure forms a bridge-like structure that can withstand pressure from clothing. It is more convenient to apply to specific body parts, such as the chest and rib areas, isolating clothing from the damaged area. Medication can be applied to the damaged area without the need for gauze coverage, increasing breathability and accelerating skin repair. Attached Figure Description

[0017] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar structures and similar variations of the present invention should be included within the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of description and is not intended to limit the technical solution of the present invention.
[0018] like Figures 1-7As shown, a skin-clothing contact-prevention device of the present invention includes a first retractable main rod 1 and a second retractable main rod 2 arranged in parallel at intervals. Each of the first retractable main rod 1 and the second retractable main rod 2 includes a first retractable end 3 and a second retractable end 4. A telescopic locking mechanism is provided between the second retractable end 4 and the first retractable end 3. The first retractable main rod 1 and the second retractable main rod 2 are connected by an extension-contraction structure 5.
[0019] Each of the first telescopic ends 3 and the second telescopic ends 4 has a support structure 6 at its bottom, and each of the support structures 6 has an adhesive structure at its bottom. Each of the first telescopic ends 3 and the second telescopic ends 4 has a rotating support fixing structure 7 at its top. Each of the rotating support fixing structures 7 includes a fixing tube 8 and a rotating rod 9. The fixing tube 8 is fixedly connected to the corresponding first telescopic end 3 or second telescopic end 4. A circumferential rotating pair and an axial limiting structure are provided between the lower end of the rotating rod 9 and the fixing tube 8. At least four claw-shaped structures 10 are distributed at intervals along the circumferential direction on the upper end of the rotating rod 9. Each of the claw-shaped structures 10 has at least four fine tooth-shaped protrusions 11 on its upper surface.
[0020] Specifically, the adhesive structure is a double-sided circular adhesive disposable consumable, with one side adhering to the skin and the other side adhering to the bottom surface of the support structure 6.
[0021] In use, the support structure 6 is attached to the surface of normal human skin using an adhesive structure. The rotating support and fixing structure 7 is then placed tightly against clothing, and the fine tooth-like protrusions 11 increase the friction with the clothing. The unfolded length of the stretching and contracting structure 5 is adjusted according to the area of the patient's skin injury, thereby adjusting the distance between the first retractable main rod 1 and the second retractable main rod 2, allowing for flexible adjustment of the support area to accommodate different skin injury areas.
[0022] This invention is lightweight and portable, and can be used simply by sticking it to the skin. By setting four rotating support fixing structures 7 and support structures 6, the overall structure formed by the unfolding and contraction structure 5 can withstand the pressure from clothing. It is more convenient to apply to special body parts, such as the chest and rib areas, to isolate clothing from the damaged area. The damaged area can be covered with medicine without the need for gauze, which increases breathability and accelerates skin repair.
[0023] This invention can be used for patients with shingles, burns, and other skin injuries where contact between the skin and clothing needs to be avoided. This invention is portable, does not interfere with daily activities, and avoids damage caused by skin-clothing contact, promoting wound healing. For patients with postherpetic neuralgia, it can also reduce contact-induced pain and hyperalgesia caused by friction between clothing and skin. For patients with contact neuralgia and hyperalgesia, the absence of contact between clothing and the affected area reduces pain caused by friction, making activities that previously caused pain no longer taboo or frightening.
[0024] Furthermore, the telescopic structure 5 includes a first linkage mechanism and a second linkage mechanism. Each linkage mechanism includes a first rotating shaft 12 and a second rotating shaft 13. The first rotating shaft 12 and the second rotating shaft 13 of the first linkage mechanism are respectively connected to the first telescopic end 3 of the first telescopic main rod 1 and the first telescopic end 3 of the second telescopic main rod 2. The first rotating shaft 12 and the second rotating shaft 13 of the second linkage mechanism are respectively connected to the second telescopic end 4 of the first telescopic main rod 1 and the second telescopic end 4 of the second telescopic main rod 2. The first rotating shaft 12 is hinged to one end of a first link 14. Then, the other end of the first link 14 is hinged to one end of the second link 16 via a third pivot 15, the other end of the second link 16 is hinged to one end of the third link 18 via a fourth pivot 17, the other end of the third link 18 is hinged to one end of the fourth link 20 via a fifth pivot 19, the other end of the fourth link 20 is hinged to one end of the fifth link 22 via a sixth pivot 21, the other end of the fifth link 22 is hinged to one end of the sixth link 24 via a seventh pivot 23, and the other end of the sixth link 24 is hinged to the second pivot 13.
[0025] The fourth pivot 17 of the first linkage mechanism is connected to the fourth pivot 17 of the second linkage mechanism via a seventh link 25, and the sixth pivot 21 of the first linkage mechanism is connected to the sixth pivot 21 of the second linkage mechanism via an eighth link 26; each of the first pivot 12, second pivot 13, third pivot 15, fourth pivot 17, fifth pivot 19, sixth pivot 21 and seventh pivot 23 is provided with a damping structure.
[0026] Specifically, the damping structure adopts a known solution in the existing technology, which involves placing multiple shims on the rotating shaft and squeezing the shims together to increase the friction between the connecting rods, thereby keeping the rotation angle at the desired position.
[0027] In this further embodiment, such as Figure 4 As shown, the stretching / contraction structure 5 is in a contracted state. Figure 5In its extended state, the extension distance can be adjusted using the first and second linkage mechanisms based on the affected skin area. The damping pivot can fix the rotation angle of the linkage, thereby fixing the unfolded length of the extension-contraction structure 5.
[0028] Furthermore, a pivot angle locking mechanism is provided between the first link 14 and the second link 16, between the second link 16 and the third link 18, between the third link 18 and the fourth link 20, between the fourth link 20 and the fifth link 22, and between the fifth link 22 and the sixth link 24.
[0029] Specifically, the pivot angle locking mechanism can be the pivot angle locking mechanism described in patent document CN202402467U.
[0030] In this further embodiment, the connecting rods are rotated to the required angle and then locked using a pivot angle locking mechanism, thereby making the extension and retraction structure 5 more stable and preventing it from retracting and unfolding arbitrarily.
[0031] Furthermore, the support structure 6 includes a support plate 30 and a telescopic rod 31. The upper end of the telescopic rod 31 is connected to the first telescopic main rod 1, and the lower end of the telescopic rod 31 is connected to the support plate 30 through a shock-absorbing spring 32. The adhesive structure is set on the bottom surface of the support plate 30.
[0032] In this further embodiment, the shock-absorbing spring 32 can reduce pressure from clothing during use.
[0033] Furthermore, each of the first telescopic main rod 1 and the second telescopic main rod 2 has an eighth rotating shaft 33 in one of their opposing side walls. The eighth rotating shaft 33 and the first telescopic main rod 1 and the second telescopic main rod 2 form a circumferential rotating pair. The two ends of the extension and retraction structure 5 are respectively connected to the eighth rotating shaft 33.
[0034] In this further embodiment, the two ends of the stretching and contracting structure 5 can rotate around the eighth pivot 33, and the angle can be adjusted according to the actual use, making it convenient to be applied to some special parts.
[0035] Specifically, the telescopic main rod, telescopic locking mechanism, and adhesive structure in this embodiment all adopt well-known solutions in the prior art, which are already understood by those skilled in the art, and will not be described in detail here.
