Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, and specifically relates to a foldable internal fistula protection cover. Background Art

[0002] The foldable internal fistula protection cover is a medical device designed specifically for protecting internal fistulas (such as arteriovenous internal fistulas of hemodialysis patients). Its main feature lies in its foldability, which facilitates carrying and storage. At the same time, it can effectively protect the internal fistula area and reduce interference and damage from external factors.

[0003] The Chinese utility model with the publication number CN216824311U proposes a foldable internal fistula protection cover: The folding structure is provided with draw grooves. The draw grooves are opened on the third split body. There are two draw grooves, which are respectively opened on the left and right sides of the third split body. The first split body and the second split body are respectively arranged in the two draw grooves in a matching manner. In the prior art, according to the individual characteristics of the patient, the first split body and the second split body can be taken out from the corresponding draw grooves.

[0004] The prior art has the following defects:

[0005] 1. Since the first split body and the second split body are arranged in the corresponding draw grooves in a matching manner, after long-term use, the contact surfaces between the first split body and the second split body and the draw grooves will gradually wear due to friction. This wear may reduce the friction coefficient between the two, making the fixation of the first split body and the second split body in the draw grooves less firm, resulting in looseness in the fit between the first split body and the second split body and the draw grooves, and it is difficult to fix them in the desired position.

[0006] 2. Since the first split body and the second split body are arranged in the corresponding draw grooves in a matching manner, the sizes of the first split body and the second split body must be smaller than that of the third split body. When the first split body and the second split body are pulled out, there are gaps between the first split body, the second split body and the third split body, resulting in the first split body and the second split body being unable to effectively adhere to the patient's arm. Content of the Utility Model

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model proposes a foldable internal fistula protection cover, which solves the problems in the prior art that the fit between the first split body and the second split body and the draw grooves becomes loose, it is difficult to fix them in the desired position, and the first split body and the second split body are unable to effectively adhere to the patient's arm.

[0008] To achieve the above object, according to an embodiment of the first aspect of the present utility model, a folding internal fistula protection cover is proposed, which includes: a first split body and two second split bodies. Pulling slots are symmetrically opened inside the first split body, and the second split bodies are arranged in the corresponding pulling slots in a matching manner. Screws are symmetrically and threadedly connected to the first split body, and threaded holes for connecting the screws are opened on both the first split body and the second split bodies. An arc-shaped plate is detachably installed on the inner side of the second split body, and placing slots are symmetrically opened on the surface of the first split body, and the placing slots are adapted to the arc-shaped plate.

[0009] As a further solution of the present utility model: both the first split body and the second split body are arc-shaped structures, the pulling slot is arc-shaped and communicates with the outside. Limiting slots are opened on the upper and lower slot walls of the pulling slot, and limiting rods are symmetrically and fixedly connected to the second split body, and the limiting rods are slidably connected in the corresponding limiting slots.

[0010] As a further solution of the present utility model: multiple threaded holes are provided on the second split body, the number of threaded holes on the first split body is the same as the number of screws, and the threaded holes on the first split body are close to the edge part of the first split body.

[0011] As a further solution of the present utility model: a pull rod is fixedly connected to the end face of the second split body.

[0012] As a further solution of the present utility model: multiple clamping blocks are fixedly connected to one side of the arc-shaped plate, clamping slots adapted to the clamping blocks are opened on the inner side of the second split body, and a fixing belt is commonly connected to the lower ends of the two second split bodies.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Gradually pull out the second split body from the corresponding pulling slot until the second split body meets the individual characteristics of the patient. At this time, the threaded hole of the first split body overlaps with one of the threaded holes of the second split body, and rotate the screw so that the screw is threadedly connected to the overlapping threaded hole to fix the second split body. Using the threaded connection method does not need to consider the problem of fitting loosening.

[0015] 2. In order to make the second split body fit the patient's arm more closely, an arc-shaped plate is detachably installed on the inner side of the second split body. The design of the arc-shaped plate can fill the gap between the second split body and the first split body to a certain extent, reducing the shaking or instability caused by the gap.

[0021] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4 shown, a foldable internal fistula protection cover includes: a first split body 1 and two second split bodies 2. The second split body 2 can be received into the first split body 1, and both the first split body 1 and the second split body 2 are arc-shaped structures.

[0023] Pulling grooves 102 are symmetrically formed inside the first split body 1. The pulling grooves 102 are arc-shaped and communicate with the outside. The second split body 2 is arranged in the corresponding pulling grooves 102 in a matching manner. The second split body 2 can be received into the pulling grooves 102 or pulled out from the pulling grooves 102.

[0024] Screws 5 are symmetrically threadedly connected to the first split body 1. Thread holes 7 for connecting the screws 5 are formed on both the first split body 1 and the second split body 2. Among them, multiple thread holes 7 are provided on the second split body 2. The number of thread holes 7 on the first split body 1 is the same as the number of screws 5, and the thread holes 7 on the first split body 1 are close to the edge part of the first split body 1.

[0025] The wrist sizes and shapes of different patients are different. The second split body 2 is gradually pulled out from the corresponding pulling groove 102 until the second split body 2 meets the individual characteristics of the patient. At this time, one of the thread holes 7 of the second split body 2 overlaps with the thread hole 7 of the first split body 1. The screw 5 is rotated so that the screw 5 is threadedly connected to the overlapping thread hole 7 to fix the second split body 2.

[0026] In order to prevent the second split body 2 from being overly pulled, resulting in the second split body 2 being completely pulled out from the inside of the pulling groove 102, limiting grooves are formed on the upper and lower groove walls of the pulling groove 102. Limiting rods are symmetrically and fixedly connected to the second split body 2, and the limiting rods are slidably connected in the corresponding limiting grooves.

[0027] A pull rod 6 is fixedly connected to the end face of the second split body 2. By providing the pull rod 6, it is convenient to pull out the second split body 2 from the inside of the draw slot 102.

[0028] In order to make the second split body 2 fit more closely to the patient's arm, an arc-shaped plate 3 is detachably installed on the inner side of the second split body 2. A plurality of clamping blocks 31 are fixedly connected to one side of the arc-shaped plate 3, and clamping grooves adapted to the clamping blocks 31 are formed on the inner side of the second split body 2. The arc-shaped plate 3 can be fixed on the second split body 2 by clamping the clamping blocks 31 with the clamping grooves.

[0029] Placement grooves 101 are symmetrically formed on the surface of the first split body 1 and are adapted to the arc-shaped plate 3. When the arc-shaped plate 3 is not in use, the arc-shaped plate 3 is clamped with the corresponding placement groove 101 to fix the arc-shaped plate 3 on the first split body 1.

[0030] A fixing belt 4 is commonly connected to the lower ends of the two second split bodies 2. The device can be connected to the hospital bed railing through the fixing belt 4.

[0031] Working principle:

[0032] The wrist sizes and shapes of different patients are different. The second split body 2 is gradually pulled out from the corresponding draw slot 102 until the second split body 2 meets the individual characteristics of the patient. At this time, the threaded hole 7 of the first split body 1 overlaps with one of the threaded holes 7 of the second split body 2, and the screw rod 5 is rotated so that the screw rod 5 is threadedly connected to the overlapping threaded hole 7 to fix the second split body 2.

[0033] In order to make the second split body 2 fit more closely to the patient's arm, an arc-shaped plate 3 is detachably installed on the inner side of the second split body 2. The design of the arc-shaped plate 3 can fill the gap between the second split body 2 and the first split body 1 to a certain extent, reducing the shaking or instability caused by the gap.

[0034] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
