Description

Technical Field

[0001] The utility model relates to the technical field of bandages, in particular to a first aid bandage. Background Art

[0002] Medical bandages are a very common medical product. With the continuous development of medical technology, different types of bandages and binding methods can be selected according to the different needs of patients. Among them, patients after pulmonary artery puncture need to be tied with medical bandages at the thigh root, and usually removed after 24 hours. However, most bandages cannot adjust the tension of the bandages.

[0003] In order to solve the problem of adjusting the tension of the bandage, a solution of a medical bandage with adjustable binding tension (Announcement No.: CN215273869U) was discovered through a search. When in use, the end of the bandage body and the shell can be closed into a ring through the fitting component, so that the bandage body can be tied to the patient's leg. At this time, by operating the adjustment component, the roller can drive the bandage body closed into a ring to relax or tighten, so as to facilitate the adjustment of the tension of the bandage body tied on the patient's thigh, thereby effectively preventing the patient's skin from being torn after the bandage body is removed due to excessive tightness of the bandage body.

[0004] In the existing process of using the above-mentioned bandage body, although the tension of the bandage body can be adjusted, one end of the bandage body is attached to the Velcro thorn surface by the Velcro fleece surface, and when the bandage body is wrapped around the injured skin surface of the patient, the injured skin surface of the patient will move unconsciously, thereby folding the Velcro fleece surface and the Velcro thorn surface, causing the Velcro fleece surface to separate from the Velcro thorn surface, thereby causing the bandage body to be released from the injured skin surface of the patient, and the bandage body is not fixed firmly enough.

[0005] In view of this, we launched a first aid bandage. Utility Model Content

[0006] The purpose of the utility model is to provide a first aid bandage to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a first aid bandage, comprising:

[0028] A fixed box 2, wherein a worm 8 is connected to the interior of the fixed box 2, and a worm wheel 7 is meshed on the surface of the worm 8;

[0029] A rotating roller 24, one end of which is connected to the surface of the worm gear 7, the surface of which is connected to the bandage body 1, and the bandage body 1 is fixedly connected to the rotating roller 24;

[0030] A connecting plate 5, wherein the connecting plate 5 is connected to one side of the fixing box 2, the connection between the connecting plate 5 and the fixing box 2 is a fixed connection, and a fixing frame 9 is fixedly connected to the top of the connecting plate 5;

[0031] A connecting cavity 10, wherein the connecting cavity 10 is provided inside the fixing frame 9, and one end of the bandage body 1 extends into the connecting cavity 10;

[0032] A fixing mechanism is disposed inside the fixing frame 9 , and the lifting plate 14 of the fixing mechanism drives the plug-in column 15 to penetrate the bandage body 1 , so that the bandage body 1 can be fixed inside the fixing frame 9 .

[0033] The fixing mechanism includes a fixing cavity 13 opened inside the fixing frame 9, and the fixing cavity 13 and the fixing frame 9 are integrally formed. The lifting plate 14 is slidably connected to the inside of the fixing cavity 13, and the plug-in column 15 is connected to the bottom of the lifting plate 14. When the lifting plate 14 is driven, the lifting plate 14 will drive the plug-in column 15 to move. A fixing groove 19 is opened inside the fixing frame 9, and a first spring 21 is connected to the inside of the fixing groove 19. A moving plate 20 is connected to one side of the first spring 21, and a fixed block 18 is connected to one side of the moving plate 20. The first spring 21 can use its own elastic force to push the moving plate 20 and the fixed block 18 to the initial position. Plug-in grooves 17 for plugging in the fixed block 18 are respectively opened on both sides of the interior of the lifting plate 14. The surface of the plug-in column 15 is sleeved with a second spring 16. After the lifting plate 14 drives the plug-in column 15 to move, the second spring 16 on the surface of the plug-in column 15 will be squeezed.

[0034] The top of the lifting plate 14 is connected with a fixing rod 12 , and the fixing rod 12 passes through the fixing frame 9 and is connected with a pressing plate 11 , and the pressing plate 11 and the fixing rod 12 are fixedly connected.

[0035] An elastic rope 23 is connected to the surface of the fixing frame 9, and one end of the elastic rope 23 is connected to a latch 22, which passes through the fixing rod 12. After the latch 22 passes through the fixing rod 12, the fixing rod 12 can be fixed to prevent the operator from accidentally touching it, and the fixing rod 12 cannot find the latch 22.

[0036] The bottom of the fixing box 2 is connected with a protective pad 6, which can protect the patient's skin and prevent the fixing box 2 from directly contacting the patient's skin.

[0037] The top of the worm 8 is connected with a rotating column 3, and the rotating column 3 passes through the fixed box 2 and is connected with a turntable 4. The surface of the turntable 4 is connected with anti-skid grooves, so that the operator's hands can better hold the turntable 4.

[0038] Specifically, when in use, the bandage body 1 is wrapped around the injured part of the patient. After wrapping, one end of the bandage body 1 is inserted into the interior of the connecting cavity 10, and then the latch 22 is taken out, so that the latch 22 cancels the fixation of the fixing rod 12. In order to prevent the latch 22 from falling, the elastic rope 23 presses the pressing plate 11, so that the pressing plate 11 drives the fixing rod 12 to move, and the fixing rod 12 drives the lifting plate 14 to move downward in the fixing cavity 13. The lifting plate 14 drives the plug-in column 15 to penetrate the bandage body 1 and then insert it into the interior of the fixing frame 9, and the second spring 16 on the surface of the plug-in column 15 is compressed, so that the bandage body 1 can be fixed, and the fixation is more firm.

[0039] During the movement of the lifting plate 14, the lifting plate 14 will squeeze the fixed block 18, and the fixed block 18 will drive the moving plate 20 to move into the fixed groove 19, and the moving plate 20 will squeeze the first spring 21 to compress the first spring 21. After the lifting plate 14 moves to a certain position, the plug-in groove 17 inside the lifting plate 14 will be aligned with the fixed block 18, so that the elastic force of the first spring 21 itself is used to insert the fixed block 18 into the plug-in groove 17, thereby fixing the lifting plate 14 to prevent the lifting plate 14 from moving upward;

[0040] Then, rotate the turntable 4 to allow the turntable 4 to drive the rotating column 3 to rotate, thereby allowing the rotating column 3 to drive the worm 8 to rotate. Since the worm 8 is meshing with the worm wheel 7, the worm wheel 7 will be driven, and the worm wheel 7 drives the rotating roller 24 to rotate. Since the surface of the rotating roller 24 is connected to the other end of the bandage body 1, the bandage body 1 can be wrapped around the surface of the rotating roller 24, thereby adjusting the tightness of the bandage body 1, which is more convenient to use.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
