Description

Technical Field

[0001] The invention relates to the field of treatment of paronychia, and in particular to a paronychia treatment device which can be adjusted in steps and is developed for patients to treat paronychia at home by themselves. Background Art

[0002] Paronychia is a common disease that occurs in people of all ages. Most patients develop this disease because their nails change shape after trauma or excessive trimming, and then penetrate deep into the nail groove. Paronychia is particularly prone to occur on the big toes of both feet, and the disease may occur in the nail grooves on both sides. Although paronychia is not fatal, the resulting open skin is prone to wound infection, and in severe cases, it may induce osteomyelitis. And because the nail groove is densely populated with nerve endings, once it is accidentally touched, it will cause severe pain, seriously affecting the patient's normal life.

[0003] For paronychia, the existing treatment technology is mainly to remove the nail. However, nail removal cannot correct the structure of the nail. Paronychia cannot be eradicated by simply removing the nail. Paronychia may still recur, causing great pain to the patient's body and mind. In addition, there are some plasters for treating paronychia on the market, but different paronychia patients cannot be generalized. The medicine that is effective for some patients may not work at all for other patients, and may even cause irritation, inflammation and infection of the wound.

[0004] Based on this situation, in recent years, some treatment products that correct the shape of nails have gradually emerged. They achieve the purpose of treating mild and moderate paronychia by inducing the nails to return to their normal shape. This has been proven to be a feasible method by the medical community. As in the prior art, Chinese patent document CN104921787A discloses a paronychia treatment device, which includes a spring piece, a lower gasket and a nail hook, wherein the spring piece is arranged above the nail, and the spring piece is bent along the upper end surface of the nail, the gasket is arranged below the nail and fixed to the spring piece by bolts, and the nail hook includes a hook handle and an arc portion. The hook handle of the nail hook is fixed to the end of the spring piece by a thread, the hook handle of the nail hook is connected to the hook arc portion, and the hook arc end of the nail hook is stuck on both sides of the lower end of the nail.

[0005] The paronychia treatment device in the above-mentioned prior art can prevent the nail from growing into the flesh by clamping the curved end of the hook of the nail hook under the nail, thereby achieving the purpose of treatment. However, the paronychia treatment device in the above-mentioned prior art still has many shortcomings. On the one hand, it is directly fixed to the nail through shrapnel, gasket, and nail hook, but due to the limited length of human nails, this fixing method is not stable and is easy to fall off during use; on the other hand, due to the differences in nails and shapes of each person, the treatment device in the above-mentioned prior art is difficult to achieve universality. Therefore, the inventor of this application hopes to develop a new type of paronychia treatment device, which can treat paronychia while also having the advantages of not easy to fall off and strong universality, so as to ensure the convenience and comfort of patients. Summary of the invention

[0006] The present application aims to solve the technical problems in the prior art that the paronychia treatment device is easy to fall off during use, has poor versatility, and has poor convenience and comfort, and thus provides a paronychia treatment device that is not easy to fall off, has strong versatility, and is comfortable and can be adjusted step by step for patients to use at home.

[0007] The technical solution adopted by this application to solve the above technical problems is:

[0008] A paronychia treatment device with step-adjustable adjustment comprises: a sleeve, the sleeve being provided with a tension adjustment structure in a circumferential direction; a step-adjustment mechanism fixedly connected to the sleeve, the step-adjustment mechanism being provided with a ratchet, the position of the ratchet being suitable for adjustment in a vertical direction; a treatment pad fixedly connected to the ratchet, the treatment pad being located outside an opening at one end of the sleeve and extending toward the sleeve.

[0009] The upper cylinder of the sleeve fits against the nail when in use, and the lower cylinder of the sleeve is in an arc shape.

[0010] The tightness adjustment structure is located on the upper cylinder.

[0011] A V-shaped structural groove is formed on the upper surface of the treatment pad, and the V-shaped opening of the V-shaped structural groove gradually shrinks along the direction extending from the outer side of the sleeve to the sleeve.

[0012] The thickness of the groove wall of the V-shaped structural groove gradually decreases along the direction extending from the outer side of the sleeve to the sleeve.

[0013] The step adjustment mechanism includes: a ratchet bar, which is mounted on a fixed rod extending in a vertical direction and is suitable for sliding along the fixed rod. A ratchet is arranged on one side of the ratchet bar, and the ratchet is arranged facing downward; an active rod, on which an active claw is arranged, and the active claw is installed on the active rod through a rotating shaft and extends upward obliquely from the active rod; the active rod drives the claw tip of the active claw to fit the ratchet and move downward through positive rotation, and drives the active claw to push the ratchet to move upward through reverse rotation; a stopping claw and a first biasing member, and the stopping claw is clamped in the ratchet of the ratchet bar under the biasing force of the first biasing member.

[0014] When the active claw rotates along the rotation axis to a position, the claw tip leaves the ratchet tooth.

[0015] A second biasing member is also provided, and the second biasing member is arranged on the movement path of the active rod for positive rotation.

[0016] A limiting device is arranged on the motion path of the active rod for reverse rotation.

[0017] The side wall of the sleeve rotates from the starting point to the end point along the circumferential direction, and the sleeve rotates from the starting point side to the end point side along the circumferential direction, forming an overlap between the starting point side and the end point side, and a ratchet adjustment structure is provided on the overlapping portion.

[0018] The step-adjustable paronychia treatment device of the present invention comprises a sleeve, a treatment gasket and a step-adjustment mechanism. The sleeve is used to fix the treatment device to the big toe, and has a flat upper portion and an arc-shaped lower portion, which can be used to fit the physiological curve of the toe (finger). As a preferred embodiment, the sleeve is provided with a tightness adjustment structure, so that the size of the sleeve can be adjusted, so that the sleeve can be suitable for being mounted on different toes (fingers), so that the device can be stably fixed to prevent the device from falling off during use. Also as a preferred embodiment, the upper portion of the paronychia treatment device of the present invention is an overlapping design, and is interconnected by ratchets, so as to achieve tightness adjustment, suitable for different toe (finger) types.

[0019] The treatment pad of the present invention is formed with a V-shaped groove structure on its upper surface, the opening of the V-shaped structure is arranged upward, and gradually shrinks along the direction extending from the outer side of the sleeve to the sleeve, so that a narrow groove structure is formed on the side facing the sleeve. This structure is consistent with the structure of a normal person's toe (fingernail) bed, and can be inserted into the side edge of the nail bed, thereby separating the toe (fingernail) from the flesh, preventing the occurrence of inflammation, and thus achieving the purpose of treatment. At the same time, the present invention arranges that the thickness and width of the treatment pad gradually decrease along the direction extending from the outer side of the sleeve to the sleeve, so that a thin "end" structure is formed on the side of the treatment pad facing the sleeve, making it easy to insert into the nail bed.

[0020] The step adjustment mechanism of the present invention realizes the step adjustment of the height of the treatment pad through the spines, the active claws and the stop claws, and can always keep the pad in close contact with the nail inserted into the nail bed during the treatment, so it has good versatility and accelerates the nail remodeling process. The operation of the device described in the present invention is very convenient and does not affect the normal daily life of the patient, and is very suitable for the home treatment of paronychia.

[0021] In order to make the technical solution of the step-adjustable paronychia treatment device described in the present invention more clear, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

DETAILED DESCRIPTION

[0027] In the present embodiment, the directions such as "up", "down", "left" and "right" are relative to the use state of the device, that is, when the device is put on the user's fingers (toes), the side that fits with the nail is the "up" side, and the opposite side is the "down" side. The two sides on the line extending from top to bottom are the "left" side and the "right" side respectively.

[0028] The present embodiment provides a paronychia treatment device, including a sleeve 1, wherein the sleeve 1 is provided with a tension adjustment structure in a circumferential direction; as a preferred embodiment, the sleeve 1 in the present embodiment rotates from a starting side edge to an end side edge along a circumferential direction, and an overlap is formed between the starting side edge and the end side edge, and a ratchet adjustment structure 2 is provided on the overlapping portion, wherein the ratchet adjustment structure 2 is a ratchet arranged at the overlapping portion, and the ratchet is arranged on a pair of surfaces that are in contact with each other at the overlapping portion, and the ratchet forms a bite. In the present embodiment, the sleeve 1 is made of stainless steel, and as an optional embodiment, the sleeve 1 can be made of metal, plastic or other materials, and in the initial state, the overlapping portion of the sleeve 1 is as follows Figure 1 and Figure 2 The figure shows the state of the sleeve when it is the tightest, that is, the smallest size. When the sleeve needs to be adjusted to be larger, it is only necessary to open the sleeve so that the two overlapping parts move to both sides. At this time, under the action of stress, the two overlapping parts tend to return to the initial position state, but due to the bite of the ratchet, the sleeve will form a stable state, thereby achieving size adjustment. The upper cylinder of the sleeve 1 is in a gentle arc shape, which fits the nail when in use, and the lower cylinder of the sleeve 1 is in a circular arc shape. In this embodiment, the overlapping part of the sleeve 1 is located on the upper cylinder. In this embodiment, the circumference of the sleeve 1 in the initial state is 40mm, and the circumference when adjusted to the maximum size is 80mm, which can be fitted on fingers (toes) of different sizes.

[0029] The paronychia treatment device also includes a step adjustment mechanism, which is fixedly connected to the sleeve 1. In this embodiment, a fixing plate 14 is provided on the side of one end surface of the sleeve 1. The fixing plate 14 is fixed to the sleeve 1 by welding or the like, and the step adjustment mechanism is installed on the fixing plate 14.

[0030] The step adjustment mechanism in this embodiment specifically includes: a ratchet 10, which is mounted on a fixed rod 16 extending in the vertical direction and is suitable for sliding along the fixed rod 16; the fixed rod 16 is fixedly connected to the fixed plate 14, and a stopper is provided at the bottom end of the fixed rod to prevent the ratchet 10 from falling off the fixed rod when it falls. A ratchet is provided on one side of the ratchet 10, and the ratchet is arranged obliquely downward, that is, the tip of the tooth portion of the ratchet is arranged obliquely downward, and the lower surface of the tooth portion of the ratchet forms an acute angle with the axial direction of the ratchet 10. In this embodiment, the length of the ratchet 10 is 10-20mm, and the ratchet 10 has a plurality of ratchet teeth, and the ratchet teeth are evenly distributed on the ratchet 10. A therapeutic pad 11 is fixed to the top of the ratchet 10.

[0031] The step adjustment mechanism also includes:

[0032] An active rod 8 is provided with an active claw 6. The claw tip of the active claw 6 is located between the ratchet teeth of the ratchet bar 10, that is, between two adjacent ratchet teeth of the ratchet bar 10. The active rod 8 is basically horizontal in the initial state, and the active claw 6 extends from the active rod 8 to the oblique upper side of the active rod 8. The active rod 8 described in this embodiment is suitable for rotating along a first rotation axis 12, and the first rotation axis 12 is arranged close to the ratchet bar 10. The active claw 6 is installed on the active rod 8 through a second rotation axis 13, and the active claw is suitable for rotating freely along the second rotation axis 13. The active rod 8 is suitable for driving the active claw to move downward in contact with the ratchet teeth of the ratchet bar through forward rotation, and pushing the ratchet teeth to move upward through reverse rotation.

[0033] The stop pawl 7 and the first biasing member 3, the stop pawl 7 is clamped in the ratchet teeth of the ratchet bar 10 under the biasing force of the first biasing member 3. The first biasing member 3 described in this embodiment is an arc-shaped elastic sheet, which is arranged to abut against the stop pawl 7, and the opening direction of the arc-shaped elastic sheet is arranged to face away from the stop pawl 7, so that the arc-shaped elastic sheet bends toward the stop pawl 7, and applies a force pointing to the direction of the ratchet bar 10 to the stop pawl 7, so that the stop pawl 7 is clamped in the ratchet teeth of the ratchet bar 10. In order to make the operation smoother, the side of the stop pawl 7 in contact with the first biasing member 3 is also set as an arc-shaped side. As a preferred embodiment, the step adjustment mechanism is also provided with a stop rod 4, and the stop rod 4 is connected to the stop claw 7, and the two are fixedly connected and do not rotate relative to each other. The stop rod 4 is suitable for driving the stop claw 7 to rotate along the third rotation axis and disengage from the ratchet. In this embodiment, the connecting axis between the stop rod 4 and the stop claw 7 is the third rotation axis (not shown in the figure).

[0034] Also as a preferred embodiment, this embodiment is further provided with a second biasing member 9, and the second biasing member 9 is arranged on the motion path of the active rod 8 for forward rotation. In the initial state, the active rod 8 is basically in a horizontal state, and the second biasing member 9 is located directly below the active rod. In this embodiment, the second biasing member 9 is also an arc-shaped spring sheet, and the arc-shaped opening direction of the arc-shaped spring sheet is arranged opposite to the active rod 8, so that the arc-shaped spring sheet bends toward the active rod 8. When the active rod 8 is pressed down, the arc-shaped spring sheet applies a force in the opposite direction to the active rod 8, and the side surface of the active rod 8 facing the second biasing member 9 is also arranged as an arc surface.

[0035] In addition, a limiting device 15 is also provided on the motion path of the active rod 8 for reverse rotation. In this embodiment, in the initial state, the limiting device 15 is in conflict with the active rod 8 and is located above the active rod 8, that is, on the side opposite to the second biasing member 9. The limiting device 15 is used to limit the active rod 8 so that the active rod 8 does not continue to rotate after returning to the initial state through reverse rotation, thereby completing the reset operation of the active rod 8. In this embodiment, the limiting device 15 is a limiting rod.

[0036] According to this embodiment Figure 2As shown in the perspective in the figure, in the initial state, the tip of the active claw 6 is located between the first ratchet tooth and the second ratchet tooth, and the active rod 8 is basically in a horizontal state. When the active rod 8 rotates clockwise relative to the first rotation axis 12, that is, when the active rod 8 is pressed down, the active rod 8 drives the active claw 6 to move downward in contact with the ratchet teeth of the ratchet strip 10. At this time, the active claw 6 rotates counterclockwise relative to the active rod 8 along the second rotation axis 13 under the action of gravity, so as to fall to the second ratchet tooth and the position located at the second ratchet tooth. The active rod 8 is released between the third ratchet teeth below. The active rod 8 rotates in the opposite direction, that is, counterclockwise, under the action of the biasing force applied by the second biasing member 9. At this time, the active claw 6 rotates clockwise relative to the active rod 8 along the second rotation axis 13 under the combined action of the thrust of the active rod 8 and the reaction force of the ratchet teeth of the ratchet bar, and pushes the second ratchet teeth to move upward. When the active rod 8 returns to the initial state again, it stops moving under the prevention of the limit device 15. At this time, the ratchet bar 10 completes an upward movement. By repeating the above operation, the ratchet bar can be continuously moved upward, thereby increasing the height of the treatment pad relative to the sleeve. In the process of lifting the ratchet bar, the stop claw 7 is stuck in the ratchet teeth of the ratchet bar under the action of the biasing force, the ratchet teeth rise, and the stop claw slides relative to the ratchet bar to a ratchet tooth located below, and transmits the biasing force from the first biasing member to the ratchet teeth, thereby preventing the ratchet bar from sliding downward. When the ratchet 10 needs to move downward, it is only necessary to operate the stop rod 4 to drive the stop claw 7 to rotate along the third rotation axis and disengage from the ratchet, and then operate the active claw 6 to rotate along the second rotation axis 13 in a direction away from the ratchet, so that the active claw disengages from the ratchet, and the ratchet 10 can automatically fall back under the action of gravity. As a preferred embodiment, the two side surfaces of the active claw 6 extending from the claw tip to the tail located at the second rotation axis, that is, the two side surfaces located on the clockwise side and the counterclockwise side, are both set as arc surfaces, so as to prevent it from being "stuck" with the ratchet, and also facilitate it to be rotated out from between the ratchet teeth of the ratchet.

[0037] As a preferred embodiment, in this embodiment, the width of the treatment pad 11 in the direction extending from the outside of the sleeve 1 to the sleeve 1 gradually decreases, and a groove is formed on the upper surface of the treatment pad. The groove in this embodiment is a V-shaped structural groove 111, and the opening of the V-shaped structural groove 111 gradually shrinks along the direction extending from the outside of the sleeve to the sleeve to form a V-shaped opening, and the opening is set upward, and the thickness of the groove wall of the V-shaped structural groove in the vertical direction gradually decreases along the direction extending from the outside of the sleeve to the sleeve to form a wedge shape, so that the treatment pad has a thin and narrow end, which is convenient for insertion into the nail groove and matches the shape of the nail at the nail groove.

[0038] In this embodiment, the step adjustment mechanism and the treatment pad 11 are arranged on one side of the sleeve 1. As an optional embodiment, the step adjustment mechanism and the treatment pad 11 can be arranged on the left or right side of the sleeve 1, so as to treat the symptoms of paronychia on one side. Also as an optional embodiment, the step adjustment mechanism and the treatment pad 11 can be arranged in two sets, and are respectively located on both sides of the sleeve 1, so as to treat the symptoms of paronychia on both sides of the nail at the same time.

[0039] The method of using the paronychia treatment device described in this embodiment is:

[0040] The sleeve 1 is put on the finger or toe to be treated, and the size of the sleeve 1 is adjusted by the tension adjustment structure so that the sleeve 1 can be stably fixed on the finger or toe. In the initial state, the spine 10 is located at the bottom end of the fixing rod. When the height needs to be adjusted, the active rod 8 can be operated to lift the position of the spine 10, thereby driving the treatment pad 11 to rise, so that the position of the treatment pad 11 corresponds to the position of the nail groove of the nail to be treated, and the front end of the treatment pad 11 is inserted into the nail groove for treatment. When the treatment process is over, the sleeve 1 can be removed, and the stop rod 4 is pressed down to disengage the stop claw 7 from the ratchet, and the active claw 6 is rotated at the same time to disengage it from the ratchet. The spine 10 can fall off to the bottom along the fixing rod under the action of its own gravity.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the claims.
