Description

TECHNICAL FIELD

[0001] The utility model relates to elastic bandage technical field, specifically point to a kind of elastic bandage of back call. BACKGROUND

[0002] The elastic bandage locking principle on the market is basically the same as the structure and principle of ordinary industrial cable tie, and it is easy to tighten by pulling forward. In order to prevent reverse loosening, the reverse slope angle of the pull bar slot on the structure is more than 80°, which is beneficial to ensure the self-locking reliability of the product.

[0003] When the pull handle needs to be loosened to adjust the tightness of the bandage during clinical use, only a sharp object such as tweezers can be used to push the pull handle out of the pull bar slot, which is very inconvenient to operate, and even the wound can be easily touched, resulting in poor patient experience.

[0004] The present application provides an elastic bandage that can be adjusted back, which changes the structure of the pull handle. When the pull handle needs to be loosened to adjust the tightness of the bandage during clinical use, the patient can slightly press the tail of the pull handle with his hand, and the front end of the handle will exit the pull bar slot, making the operation more convenient. SUMMARY

[0005] The present application aims to solve the problem of poor back call flexibility and poor patient experience in the prior art.

[0006] The present application provides an elastic bandage that can be adjusted back, which changes the structure of the pull handle. When the pull handle needs to be loosened to adjust the tightness of the bandage during clinical use, the patient can slightly press the tail of the pull handle with his hand, and the front end of the handle will exit the pull bar slot, making the operation more convenient.

[0007] Preferred technical solution one: the pull handle seat is fixed on one side of the bottom layer two, the pull handle seat rear wall is provided with a window, and the locking degree adjustment handle is located at one end of the front side of the pull handle seat. The pull handle passes through the window and is carded with the protrusion at the end of the locking degree adjustment handle.

[0008] Preferred technical solution two: the locking degree adjustment handle is fixed to the pull handle seat, and the locking degree adjustment handle has a certain toughness, so that when force is applied, the rear end of the locking degree adjustment handle can be pressed to make the front protrusion away from the pull handle.

[0009] Preferred technical solution three: the other end of the front side of the pull handle seat is provided with an extension section, the extension section and the locking degree adjustment handle are located on both sides of the pull handle respectively, and the extension section and the pull handle are in sliding contact.

[0010] Preferred technical solution four: the bottom side of the bottom layer one and the bottom layer two is adhered with release paper.

[0011] The fifth preferred technical solution is that the plurality of groups of the pull strips and the pull strip seats are distributed on the first bottom layer and the second bottom layer.

[0012] The above structure makes the present solution have the following beneficial effects:

[0013] 1. By changing the structure of the pull strip seat, the callback operation is convenient and simple, and the patient experience is improved.

[0014] 2. The material is reasonably selected to ensure that the automatic locking function is firm and reliable. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-5The adjustable elastic bandage includes a bottom layer 1 with a fixed pull strip base 4 and a bottom layer 2 with a fixed pull strip 5. Release paper 8 is adhered to the bottom sides of the bottom layer 1 and the bottom layer 2. A locking adjustment handle 3 is provided on the pull strip base 4. After the pull strip 5 slides through the pull strip base 4, the groove 52 on one side of the pull strip 5 engages with the protrusion 31 at the end of the locking adjustment handle 3 to fix the position of the pull strip 5. When in use, the bottom surfaces of the bottom layer 1 and the bottom layer 2 are pasted to both sides of the wound. After the pull strip 5 is tightened, it engages with the locking adjustment handle 3 to close the wound. When it is necessary to adjust back, press the locking adjustment handle 3 to move the end protrusion 31 away from the pull strip 5 to release the locking state and adjust the tension of the wound closure.

[0024] The bottom side of the pull strip 4 is fixedly connected to the first convex plate 41 and bonded to the bottom layer 1. At the same time, the top surface of the first convex plate 41 is covered with non-woven fabric 6. The first convex plate 41 is bonded to the bottom layer 1 through a set of foam 7. The rear end of the pull strip 5 is fixedly connected to the second convex plate 51 and bonded to the bottom layer 2. At the same time, the top surface of the second convex plate 51 is also covered with non-woven fabric 6. The second convex plate 51 is also bonded to the bottom layer 2 through a set of foam 7.

[0025] Multiple sets of pull rod 5 and pull rod seat 4 are distributed on bottom layer 1 and bottom layer 2.

[0026] Please see Figure 1 and Figure 5 The adjustable elastic strap has a protrusion 42 fixed on the side of the pull bar seat 4 near the bottom layer 2. A window 421 is opened on the rear wall of the protrusion 42. The locking adjustment handle 3 is located at one end of the front side of the protrusion 42. The pull bar 5 passes through the window 421 and engages with the protrusion 31 on the locking adjustment handle 3.

[0027] The locking adjustment handle 3 is fixedly connected to the pull bar seat 4 in the middle. The protrusion 31 on the locking adjustment handle 3 is located on the front side. The rear end of the locking adjustment handle 3 functions as a handle. The locking adjustment handle 3 has a certain degree of toughness and is preferably made of nylon material with good toughness and rigidity. This allows the front protrusion 31 to be pushed out of the slot 52 and away from the pull bar 5 when the handle is retracted by pressing the rear end of the locking adjustment handle 3. Due to the lever principle, the front protrusion 31 is pushed out of the slot 52 and away from the pull bar 5 without breaking the locking adjustment handle 3. At the same time, the front side wall of the slot 52 on the side of the pull bar 5 is flat, and the rear side... The wall is sloped, so that the protrusion 31 on the locking adjustment handle 3 contacts the flat surface of the front side of the slot 52 on the pull bar 5, achieving stable engagement under the action of wound tension. When the pull bar 5 is pulled forward, the slope of the slot 52 on the pull bar 5 slides over the protrusion 31 on the locking adjustment handle 3 in sequence, which facilitates the tightening operation of the pull bar 5. After the position of the pull bar 5 is adjusted to the correct position, the pressing state of the rear end of the locking adjustment handle 3 is released, and the protrusion 31 at the front end of the locking adjustment handle 3 automatically springs back into the slot 3 of the pull bar 5, automatically locking again.

[0028] Please see Figure 1 andFigure 5 The adjustable elastic strap has an extension section 43 fixed at the front end of the protrusion 42 away from the locking adjustment handle 3. The extension section 43 contacts the other side of the pull bar 5 without the slot 52. The extension section 43 provides limiting support for the pull bar 5, ensuring that the pull bar 5 will not be tilted when engaged with the locking adjustment handle 3. The handle part on the rear side of the locking adjustment handle 3 is provided with an anti-slip structure.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
