Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of burn care, in particular to a bandage winding device for burn care. Background Art
[0002] Burns refer to a type of trauma that causes damage to body tissues due to external heat sources, chemicals, electric current, radiation, etc. This damage includes damage to the skin, tissues, blood vessels, nerves, etc. The severity of burns can be divided into first-degree burns (mild), second-degree burns (moderate), and third-degree burns (severe) based on skin histology.
[0003] In clinical practice, bandages are common medical care products. For burn patients, bandages need to be used to protect the damaged skin surface.
[0004] For example, a Chinese utility model patent with publication number CN210698016 discloses a bandage winding device for pediatric burn care, including a base frame, a first vertical pole fixedly connected to one side of the base frame, a sleeve pole movably connected to the top end of the first vertical pole, a rotating rod movably connected to the inner wall of the sleeve pole, a fixing rod fixedly connected to one end of the rotating rod, a bandage rod movably connected to one end of the fixing rod, a bandage rod movably connected to the middle part of the bandage rod, a fixing bolt threadedly connected to one end of the bandage rod away from the bandage, a second vertical pole fixedly connected to the side of the base frame away from the first vertical pole, and an arc plate fixedly connected to the top end of the second vertical pole.
[0005] However, this solution has certain defects: during the rotation of the bandage rod, for each rotation, the bandage is released by a length equivalent to the circumference of the bandage roll surface, and is wrapped around the patient's affected limb once. However, as the bandage roll is used, the circumference of the bandage roll surface decreases, and the bandage wrapped around the patient's affected limb will gradually tighten. At the same time, the limbs of different patients are of different sizes and parts, which will lead to different tightness of the bandage wrapping process. A bandage that is too loose will cause the gap to be too large, thereby increasing the space for bacteria and pollutants in the air to enter, and increasing the risk of infection. Wrapping too tightly will slow down the blood circulation in the affected area, leading to edema and even local tissue hypoxia. Utility Model Content

[0025] The bandage tension control assembly includes two drive blocks 18 disposed on the outer side of the bandage tube 14 at the two ends of the outlet slot 17. The two drive blocks 18 have the same structure and are arranged opposite to each other. A movable slot 20 is opened on the side of each drive block 18 facing the other drive block 18. Two parallel tensioning shafts 19 are disposed between the two drive blocks 18. Both ends of each tensioning shaft 19 are respectively connected to a sliding block 21. The sliding block 21 is slidably installed in the movable slot 20. A tension spring 22 is connected between the two sliding blocks 21 located in the same movable slot 20.
[0026] The limb protector 3 is an arc-shaped plate, one end of which is connected to a flexible protective belt 5, and the other end of which is provided with a fixing groove 4 that matches the width of the protective belt 5; round hairs are provided on the outer side of the protective belt 5, one end of which is connected to a Velcro 6, and the surface of the Velcro 6 is provided with bristles.
[0027] The principle and use process of this utility model:
[0028] First, open the refueling door 15 through the handle 16, put in a new bandage roll, and pass the head of the bandage through the outlet slot 17. Use a pressure plate or tweezers or other objects to spread the two tensioning shafts 19 apart. The tensioning shaft 19 pushes the sliding blocks 21 at both ends to both sides along the movable slot 20. At the same time, the tension spring 22 is stretched open. Then, pass the bandage between the two tensioning shafts 19, and loosen the tensioning shaft 19. The tension spring 22 pulls back the tensioning shaft 19 to generate friction on the bandage. Put the refueling door 15 back to complete the installation of the bandage.
[0029] When the patient needs to be bandaged, the patient's affected limb is placed on the limb support 3 so that the part to be bandaged faces the outlet slot 17, and then the protection belt 5 is picked up and inserted into the fixing slot 4 and tightened, and then the Velcro 6 at the top is attached to the protection belt 5 to complete the fixation of the limb;
[0030] Then, stick the head of the bandage to the patient's affected limb, hold the handle 11 and rotate it, so that the bandage tube 14 can be driven to rotate around the affected limb through the threaded rod 9 and the connecting rod 13. During the rotation, the bandage is automatically pulled out of the bandage tube 14, and due to the friction of the tensioning shaft 19 on the bandage, the bandage will automatically tighten when it is wrapped, and the bandage can rotate freely in the bandage tube 14. The rotation speed of the bandage roll is not affected by the rotation speed of the handle 11, thereby ensuring a balanced bandage winding effect. At the same time, when the threaded rod 9 rotates in the threaded sleeve 8, it will automatically move due to the action of the thread, so that the bandage can be automatically wound forward or backward along the patient's affected limb to keep the bandage thickness uniform.
