Description

Technical Field

[0001] This utility model relates to the field of dressing technology, and in particular to a dressing for hydrofluoric acid burns. Background Technology

[0002] Hydrofluoric acid is a mixture of water and hydrogen fluoride, primarily used in industrial applications such as glass etching, metal cleaning, and pesticide production. It is a weak acid, mainly existing in its unsplit state, allowing it to penetrate deep into the skin and soft tissues. When fluoride is released from the hydrofluoric acid in tissues, it can cause liquefactive necrosis of soft tissues and bones. Electrolyte imbalances occur when free fluoride ions combine with calcium and magnesium ions. Due to its tissue-penetrating ability, exposure to hydrofluoric acid can cause systemic toxicity; the degree of toxicity depends on the duration of exposure, the concentration of hydrofluoric acid, the route of exposure, and the size of the affected surface area.

[0003] Currently, there are no special external dressing devices for hydrofluoric acid burns in clinical practice. When applying external dressings to supplement calcium and magnesium ions, the dressing can only be soaked in a solution containing these two ions before being applied as a wet dressing. It is difficult to ensure that the dressing continuously contains these ions for absorption. Furthermore, when the dressing is too wet, the solution may overflow from the patient's body, which can easily cause skin ulceration and, in severe cases, lead to serious consequences such as suffocation.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1

[0041] Please refer to Figure 1-3 A dressing for hydrofluoric acid burns includes a waterproof layer 100, an infusion line 200, a diffusion layer 500, several diffusion membranes 400, a reservoir layer 600, and a skin-friendly adhesive layer 700. The infusion line 200 is disposed below the waterproof layer 100, and an infusion control device 300 is adapted to the input end of the infusion line 200. The several diffusion membranes 400 are all horizontally connected to the output end of the infusion line 200. The top surface of the diffusion layer 500 is fixedly connected to the bottom surfaces of the infusion line 200 and the diffusion membranes 400. The reservoir layer 600 is disposed below the diffusion layer 500, and the bottom surface of the reservoir layer 600 is fixedly connected to the top surface of the skin-friendly adhesive layer 700.

[0042] The waterproof layer 100 is a PVC plastic film covering the top layer, which can effectively prevent the solution from overflowing upwards; the terminal of the infusion pipeline 200 connects to each diffusion membrane 400, and its starting end is injected with calcium and magnesium ion solution through the infusion device, which can effectively flow into the diffusion membrane 400 through the infusion pipeline 200; the diffusion membrane 400 can effectively penetrate in the horizontal direction, so that the dressing is evenly diffused in the same horizontal direction; the diffusion layer 500 is a soft non-woven fabric layer made of needle-punched non-woven fabric material, which is conducive to rapid penetration in the vertical direction; the liquid storage layer 600 is a sponge, which is conducive to storing the solution.

[0045] Specifically, the dressing for hydrofluoric acid burns also includes several ventilation holes 800, all of which connect from top to bottom to the reservoir layer 600 and the skin-friendly adhesive layer 700.

[0046] Through the above structural design, the vent 800 enhances the breathability of the dressing and also increases the vertical permeability of the dressing, which is conducive to the solution being able to fully act on the patient's wound and fully absorb the drug effect.

[0047] Specifically, a number of vents 800 are arranged in a matrix uniformly in the liquid storage layer 600 and the skin-friendly adhesive layer 700.

[0048] Through the above structural design, the vent holes 800 are evenly arranged and connected in the liquid storage layer 600 and the skin-friendly adhesive layer 700.

[0049] Specifically, the internal pore diameter of the liquid storage layer 600 is 2-4 mm.

[0050] Through the above structural design, in this embodiment, the pore size of the liquid storage layer 600 is 2mm, but it can also be other sizes depending on different needs.

[0051] Specifically, the diffusion membrane 400 is a natural bamboo fiber membrane or a polyacrylic acid membrane with a pore size of 0.5~1mm.

[0052] Through the above structural design, in this embodiment, the dispersion membrane 400 is a polyacrylic acid membrane with a pore size of 0.5 mm. Under different requirements, it can also be other materials and sizes. Example 2

[0053] The dressing for hydrofluoric acid burns provided in Example 1 has been further optimized, specifically, as follows: Figure 1-3 As shown, the dressing for hydrofluoric acid burns also includes a suture strip 900, which is sealed on the sides of the waterproof layer 100, the infusion line 200, the diffusion layer 500, the reservoir layer 600 and the skin-friendly adhesive layer 700, as well as the outer periphery of the top surface of the waterproof layer 100.

[0054] Through the above structural design, the stitching strip 900 is used to seal the sides and bottom edges, preventing the solution from overflowing from the side of the membrane, effectively reducing resource waste.

[0055] Specifically, the diffusion layer 500 is a non-woven soft layer with a thickness of 0.6~1.4mm.

[0056] Through the above structural design, in this embodiment, the diffusion layer 500 is a non-woven soft layer with a thickness of 0.6mm. It can also be other sizes depending on different needs.

[0057] Specifically, the bonding surface of the 900 stitching strip has weak adhesion.

[0058] Through the above structural design, the bonding surface of the suture strip 900 has weak adhesion, which is conducive to tightly adhering to the sides of the waterproof layer 100, the infusion pipeline 200, several diffusion membranes 400, the diffusion layer 500, the liquid storage layer 600 and the skin-friendly adhesive layer 700, as well as the outer periphery of the top surface of the waterproof layer 100. Example 3

[0059] The dressings for hydrofluoric acid burns provided in Example 1 or 2 were further optimized, such as... Figure 4-5 As shown, the infusion control device 300 includes a trapezoidal control guide 310 disposed on the input end of the infusion pipeline 200. The control guide 310 is provided with a clearance groove 320 and a serrated through groove 330. A roller 340 is disposed on the clearance groove 320. Guide posts 350 extending out of the through groove 330 are adapted on the left and right sides of the roller 340. The roller 340 is in contact with the infusion pipeline 200.

[0060] Through the above structural design, the infusion line 200 passes through the control guide 310, which is equipped with a roller 340. The guide post 350 of the roller 340 is locked in the through groove 330. The position of the roller 340 in the through groove 330 can be adjusted by hand. The horizontal direction of the through groove 330 forms an angle with the bottom edge of the control guide 310. When the roller 340 is closer to the angle, the squeezing force of the roller 340 in the infusion line 200 is greater, and the flow rate of the solution in the infusion line 200 is slower. Conversely, when the roller 340 is farther away from the angle, the squeezing force of the roller 340 in the infusion line 200 is smaller, and the flow rate of the solution in the infusion line 200 is faster, thereby achieving the effect of controlling the solution flow rate.

[0061] Specifically, the control guide 310 and the roller 340 are made of copper, stainless steel or PVC.

[0062] Through the above structural design, copper, as the manufacturing material, can have greater durability. In this embodiment, copper is selected as the manufacturing material for roller 340 and control guide 310.
