Abstract
The foam dressing is mainly used for protecting a wound surface after dressing change, a disposable traditional dressing patch needs to be replaced after dressing change every time, the consumable cost is increased, and due to the fact that the dressing patch is prone to being adhered to the wound, secondary damage to the normal skin of a patient and the wound surface of the wound can be caused by tearing the foam dressing when the wound is replaced. The foam dressing device capable of adding the medicine comprises a commercially available foam dressing basic patch, a medicine adding device and a sealing layer, the medicine adding device and the sealing layer are arranged in the foam dressing basic patch, and the foam dressing basic patch is sequentially composed of a water blocking layer, a foam layer, a bonding layer and an anti-adhesion layer structure. According to the technology, during secondary dressing change, the whole foam dressing patch does not need to be taken down or replaced, dressing change operation can be completed only by adding medicine through the medicine adding opening, consumables and related expenses are saved, and the technology is simple and convenient to operate. Damage to normal skin or wounds caused by replacement and tearing of the foam dressing is reduced, and wound healing can be promoted through the comprehensive effect.
