Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a sponge product PH is neutral, reducing substance content is low, biological safety is high, and the inside aseptic space that is of aluminium foil bag can be preserved for a long time, use the negative pressure drainage sponge that infects the risk low.
Technical Field
The negative pressure drainage technique is known as a brand new method for treating various complex wound surfaces and for deep drainage, and is originally initiated by doctor Fleischmann, university of ULM, germany, in 1992 and is firstly used for treating soft tissue defects and infectious wound surfaces in the field of orthopedics. By using the negative pressure drainage sponge and matching with the negative pressure sealing principle, the sponge is used as a new treatment technology for repairing the damaged surface, and since the first creation in the 90 s of the 20 th century, the application effect is determined quickly and recommended to the clinical treatment of various soft tissue defects and infections.
The negative pressure drainage sponge is used as the most core component, and the performance of the sponge plays a key role in the negative pressure drainage technology. Most of the negative pressure drainage sponges sold in the market at present adopt an irradiation sterilization process, the irradiation sterilization achieves the effect of killing bacteria by providing electron beams and energy, in the sterilization process, due to the introduction of high-energy electron beams, molecular cross-linking points of wet sponges can be damaged, partial small molecular substances are decomposed to cause the rise of reducing substances in products, the pH value of the products is reduced to be acidic, the sponges are used for wound surfaces, a strong acid environment is provided, the granulation tissue growth process is damaged, the reducing substances in sponge products can also cause the cytotoxicity test range of the sponge products to be lower, and the sponge products are not beneficial to wound surface healing. Meanwhile, in order to ensure that the sponge keeps a wet state for a long time, a layer of aluminum foil bag outer package is required to be added on the outer layer of the sponge of the commercially available negative pressure sponge, and due to the existing sterilization process, the inside of the sponge cannot be well sterilized through the aluminum foil bag no matter ethylene oxide sterilization or irradiation sterilization, so that a non-sterile space exists between the aluminum foil bag outer package and the inner package, and the risk of wound infection is high in the using process of the product.
