Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an auxiliary bandaging device for hand and foot wounds. Background Technology

[0002] Due to the multi-joint structure of the hands, fingers / feet, and toes, and their location at the extremities, applying existing elastic mesh bandages to incisions / wounds presents certain difficulties and low efficiency. The pressure supplied by existing dressings is unstable (too loose can lead to poor hemostasis, while too tight can cause ischemia or even necrosis of the hands, fingers, feet, and toes), thus increasing the risk of postoperative complications. Currently, common methods for bandaging hands, fingers, feet, and toes include covering with ordinary gauze and securing with adhesive tape, ordinary gauze and securing with elastic bandages, adhesive bandages, and applying antibacterial gel to the exposed area, with gauze and elastic bandages applying pressure being the most prevalent. Furthermore, current bandaging methods largely rely on manual application by medical staff, especially when opening the elastic mesh and attempting to accurately bandage the wound. Insufficient opening can make it difficult to slip the mesh onto the wound or cause friction, hindering wound healing.

[0003] Therefore, there is an urgent need to provide a bandaging tool for hand and foot wounds that can both efficiently bandage and stably apply appropriate pressure. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides an auxiliary bandaging device for hand and foot wounds. The opening angle of the umbrella end of the device can be flexibly adjusted, making it convenient for medical staff to bandage wounds using an elastic net, thus solving the problems of difficult adjustment and complicated operation during the bandaging process.

[0005] The present invention adopts the following technical solution:

[0006] A device for assisting in bandaging hand and foot wounds, characterized in that it comprises a screw, a cylindrical ring, several fan-shaped blades, and several threaded inner tubes;

[0007] The inner side of the threaded inner liner is provided with threads, and the outer side is provided with several pairs of rings. An elastic structure passes through the rings. Several threaded inner liners are combined to form a hollow frustum shape, so that the surface of the hollow channel forms a complete internal thread.

[0008] The tip of the fan blade is fixed to the outside of the threaded inner liner. The tip of the fan blade and the threaded inner liner are located inside the cylindrical ring, forming an umbrella end on the outside of the cylindrical ring. The fan blade is provided with fixing buckles on both sides. Several pairs of rings are provided at the bottom of the inner side of the cylindrical ring. The fixing buckles match the rings, so that the fan blade and the threaded inner liner can rotate around the bottom of the cylindrical ring.

[0009] The front section of the screw is an external thread that mates with the threaded inner liner, the diameter of the middle section gradually increases, and the tail section is a holding section; when the screw is screwed in, the threaded inner liner is opened, causing the diameter of the umbrella end to decrease.

[0010] Preferably, the elastic structure is a spring ring or a rubber ring, so that the threaded inner liner maintains a hollow frustum shape in its natural state.

[0011] Preferably, the outer diameter of the cylindrical ring is 2 to 5 cm.

[0012] Preferably, the maximum diameter of the umbrella tip is 13-15 cm, and the minimum diameter is 3-6 cm.

[0013] Preferably, the tip of the fan blade is fixed to the outside of the threaded inner liner by welding or bonding.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an auxiliary bandaging device for hand and foot wounds. When bandaging wounds, the diameter of the opening of the umbrella end of the device can be changed by adjusting the degree of screw screwing in, which makes it convenient for medical staff to use the elastic net to bandage the wound and solves the problems of difficult adjustment and complicated operation in the bandaging process.

[0024] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or it can be indirectly fixed or connected to the other feature. Furthermore, the descriptions of "upper," "lower," "left," and "right" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.

[0025] A hand and foot wound auxiliary bandaging device, referring to Figures 1-6 , including screw 3, cylindrical ring 2, several fan blades 1 and several threaded inner tubes 4;

[0026] Combination Figure 3 and 5 The inner side of the threaded inner liner 4 is provided with a thread 403, and the outer side is provided with several pairs of rings 401. An elastic structure 402 passes through the rings 401. Several threaded inner liners 4 are combined to form a... Figure 5 The hollow frustum shape shown on the left has a hollow channel surface that forms a complete internal thread;

[0027] Combination Figure 4 The tip of the fan blade 1 is fixed to the outside of the threaded inner liner 4. The tip of the fan blade and the threaded inner liner 4 are located inside the cylindrical ring 2, forming an umbrella end on the outside of the cylindrical ring 2; combined Figure 6 The fan blade 1 has fixing buckles 101 on both sides, and the inner bottom of the cylindrical ring 2 has several pairs of fixing rings 201. The fixing buckles 101 match the fixing rings 201, so that the fan blade 1 and the threaded inner liner 4 rotate around the bottom of the cylindrical ring 2.

[0028] The front section of screw 3 is an external thread that mates with the internal thread of the threaded inner liner 4. The diameter of the middle section gradually increases, and the tail section is the holding section. When screw 3 is screwed in, the threaded inner liner 4 is opened, which causes the diameter of the umbrella end of the device to decrease.

[0029] Please combine Figures 1-2 This is a schematic diagram of the bandaging device of this utility model in two different states. Figure 1 When the screw is screwed in, the diameter of the umbrella end of the device decreases; Figure 2 In its natural state, the diameter of the umbrella end of the device is relatively large.

[0030] The following is combined with Figures 3-6 Explain the principle by which this utility model device achieves the change in umbrella tip diameter, such as... Figure 3 ,5 The outer side of the threaded inner liner is provided with a ring, and an elastic structure passes through the ring. Under natural conditions, the elastic structure contracts, causing the threaded inner liner to form as follows: Figure 5 The frustum shape shown on the left is formed by welding the tips of the fan blades to the outer side of the threaded inner liner. Figure 4 The component shown has blades that move together with the threaded inner liner. In its natural state, the several threaded inner liners, under the contraction tendency of the elastic structure, exhibit the following characteristics: Figure 5 As shown on the left in its natural state, the umbrella tip of the device presents as... Figure 2 As shown, the screw has a larger diameter; when screwed in, the larger diameter section in the middle of the screw expands the threaded inner core, and the diameter of the elastic structure also increases accordingly, making it appear as shown... Figure 5 As shown on the right, the umbrella end of the device presents the following state: Figure 1 The diameter shown is decreasing. (Example:) Figure 6 The fan blades are movably connected to the fixing ring 201 at the bottom inner side of the cylindrical ring via the fixing buckle 101, allowing the fan blades to rotate around the axis of the fixing buckle at the bottom of the cylindrical ring while maintaining connection with the cylindrical ring. As the diameter of the umbrella end changes, the fan blades can move smoothly without obstruction.

[0031] Specifically, the elastic structure 402 is a spring ring or a rubber ring, which allows the threaded inner liner 4 to remain in its natural state. Figure 5 The hollow frustum shape shown on the left.

[0032] Specifically, the outer diameter of the cylindrical ring is 2 to 5 cm.

[0033] More specifically, in cases such as Figure 2 In the state shown, the maximum diameter of the umbrella tip is 13-15 cm; in the case of... Figure 1 In the state shown, the minimum diameter of the umbrella tip is 3-6 cm.

[0034] More specifically, the number of fan blades and threaded inner liner is 6, 8, 10, or 12.

[0035] The method of using this utility model when bandaging wounds is as follows:

[0036] 1. Adjust the umbrella tip diameter: Rotate the screw. The front thread of the screw engages with the internal thread of the threaded inner liner. As the screw is screwed in, the threaded inner liner is expanded, causing the umbrella tip diameter to decrease, adapting to wound areas of different sizes.

[0037] 2. Insert the elastic netting: Insert the elastic netting from the end of the umbrella, ensuring that the netting covers the wound smoothly.

[0038] 3. Secure the netting: Adjust the diameter of the umbrella end to a suitable size so that the netting fits tightly against the wound, avoiding it being too loose or too tight.

[0039] 4. Bandaging complete: After confirming that the netting is secure, remove the device to complete the bandaging.

[0040] The diameter of the umbrella end is adjusted by rotating the screw, simplifying the process of putting on and fixing the elastic netting and improving bandaging efficiency. This device allows for adjustment of the layers of the elastic netting according to the pressure requirements of the limb wound, thereby regulating pressure and finding the appropriate pressure treatment for the patient. This reduces complications such as bleeding due to insufficient pressure or limb ischemia due to excessive pressure.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
