Problems solved by technology

In this method, no matter whether the alkaline drug or the acidic drug is in contact with the wound, there is a risk of chemical burns to the wound. Movement to the direction of the barrier to complete the preparation reaction significantly increases the risk of chemical burns
Moreover, the water molecules in the air pass through the three layers in turn to cause the reaction speed to be too slow, and the drug concentration is difficult to guarantee

Embodiment 1

[0019] Embodiment 1: It is formed by separately supporting chlorite and acidic substances on the fiber material.

[0020] The fiber material is one of PVA-gelatin fibers, chitin fibers, alginate fibers, polyvinyl alcohol fibers, cellulose fibers, modified cellulose fibers, polyacrylonitrile fibers, konjac fibers, and acrylic fibers or a mixture of several;

[0021] Described chlorite is sodium chlorite solution;

[0022] The acidic substance is a citric acid solution as an activator;

[0023] The medical antibacterial dressing is formed by impregnating and drying fibers in sodium chlorite solution and mixing them with fibers impregnated in citric acid solution and drying.

[0024] When the medical antibacterial dressing is in use, it utilizes the moisture in the wound exudate to complete the activation reaction of sodium chlorite to generate chlorine dioxide. When the chlorine dioxide is produced, it completes its mixing with the wound exudate, and can immediately Disinfect...

Embodiment 2

[0025] Embodiment 2: It is formed by separately loading chlorite and acidic substances on the fiber material.

[0026] The fiber material is one or a mixture of solid fibers, hollow fibers, superfine fibers, and shell structure fibers.

[0027] Described chlorite is sodium chlorite solution;

[0028] The acidic substance is a citric acid solution as an activator;

[0029] The medical antibacterial dressing is formed by impregnating and drying fibers in sodium chlorite solution and mixing them with fibers impregnated in citric acid solution and drying.

[0030] When the medical antibacterial dressing is in use, it utilizes the moisture in the wound exudate to complete the activation reaction of sodium chlorite to generate chlorine dioxide. When the chlorine dioxide is produced, it completes its mixing with the wound exudate, and can immediately Disinfect the wound and its exudate.

Abstract

The invention discloses a medical antibacterial dressing and belongs to a medical surgical wound care material. The fiber is supported with chlorite and an acidic material, and after plasma or body fluid infiltrates the fiber, the chlorite and the acidic material are dissolved and mixed in the infiltrated material, chlorine dioxide is released, and the fiber absorbs the wound exudate while achieving an antibacterial effect. Because the antibacterial component is supported on the fiber material, is convenient to store, good in water solubility, is very easily mixed with the infiltrated material, is stable in effect, achieves broad-spectrum sterilization and the antibacterial substance is gradually released with the increasing proportion of the infiltrated material to achieve the sustained release effect, so that the action time is further prolonged, the medical antibacterial dressing is especially suitable for chronic wounds such as ulcers and burns, and absorbs wound exudate while reducing the chance of wound infection.

Description

technical field [0001] The invention relates to the technical field of medicine, and specifically discloses a medical antibacterial dressing, which belongs to a medical surgical wound care material. Background technique [0002] Antibacterial dressings currently on the market are mainly quaternary ammonium salt products, nano-silver or copper ion products, etc. For example, a bacterial cellulose composite cuprous oxide antibacterial dressing disclosed by CN105311668A and its preparation method, or directly use antibacterial used in combination with wound dressings. [0003] As the current mainstream disinfectant quaternary ammonium salt product, its effect is safe and powerful in daily disinfection, etc., but because its bactericidal band is not fully covered, especially in places like hospitals, it may appear It is a very serious problem. In recent years, the emergence of cross-infection, drug-resistant bacteria and even super viruses is sounding the alarm to people. More ...
