Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figure 1-5 The present invention discloses an activated carbon fiber medical excipient, wherein an excipient sheet 101 is disposed on the inner wall of an isolation sleeve 100, a first attachment rubber ring 102 is disposed on the bottom wall of the isolation sleeve 100, a second attachment rubber ring 103 is disposed on the bottom wall of the isolation sleeve 100, the second attachment rubber ring 103 is located in the inner cavity of the first attachment rubber ring 102, and drainage holes are evenly opened on the bottom wall of the isolation sleeve 100, the drainage holes being located between the second attachment rubber ring 103 and the first attachment rubber ring 102.
[0023] In this embodiment: the dressing sheet 101 is attached to the wound, and the second adhesive ring 103 and the first adhesive ring 102 are attached to the skin for adhesion. The second adhesive ring 103 and the first adhesive ring 102 are used to bond and seal the gap between the dressing sheet 101 and the skin. The double-layer seal of the second adhesive ring 103 and the first adhesive ring 102 can effectively prevent surface seepage leakage. When seepage affects the adhesion of the second adhesive ring 103 and causes a gap leading to leakage, the seepage can be guided through the drainage hole to the dressing sheet 101 for absorption. When there is no leakage, ventilation can be carried out through the drainage hole. This allows the device to fit tightly to the skin at the wound site, preventing leakage. The double-layer adhesive seal helps to improve the sealing performance and facilitates the absorption of seepage.
[0024] The auxiliary sheet 101 includes a mesh layer 104, the inner cavity of which is provided with an activated carbon fiber layer 105, and the upper and lower sidewalls of the activated carbon fiber layer 105 are provided with a non-woven fabric layer 106.
[0025] In this embodiment: the activated carbon in the activated carbon fiber layer 105 facilitates the adsorption of exudate, eliminates the odor in the exudate, and thus improves the comfort of use. The non-woven fabric layer 106 facilitates the protection of the activated carbon fiber layer 105. At the same time, the non-woven fabric layer 106 can also adsorb the exudate to a certain extent, which can reduce the risk of wound maceration.
[0026] The bottom walls of the first adhesive ring 102 and the second adhesive ring 103 are provided with a protective film layer 107, and the top wall of the upper non-woven fabric layer 106 is provided with a polyurethane film layer 108.
[0027] In this embodiment: by setting a protective film layer 107, the second adhesive ring 103 and the first adhesive ring 102 are protected, avoiding contact between the second adhesive ring 103 and the first adhesive ring 102 and the outside world, which affects the adsorption. This is conducive to sealing with the skin and improving practicality. By setting a polyurethane film layer 108, it can play a waterproof role and also play a bacteriostatic role.
[0028] The mesh of the mesh layer 104 is hexagonal, and the activated carbon fiber layer 105 is made of bamboo charcoal fiber.
[0029] In this embodiment: the hexagonal mesh is designed to be strong and tear-resistant, thus preventing tearing; bamboo charcoal fiber is used, which is readily available, has low production costs, and strong adsorption capacity.
[0030] The isolation sleeve 100 and the auxiliary material sheet 101 are bonded together by thermal bonding, and the non-woven fabric layer 106 and the activated carbon fiber layer 105 are bonded together by strip-shaped or dot-shaped adhesive application.
[0031] In this embodiment: during production, the sleeve is placed on the upper and lower side walls of the auxiliary material sheet 101, and the sleeve is laminated into an isolation sleeve 100 by thermal bonding, which facilitates the bonding of the isolation sleeve 100 and the auxiliary material sheet 101. The bonding of the non-woven fabric layer 106 and the activated carbon fiber layer 105 can avoid misalignment and facilitates adhesion to the wound for adsorption.
