Description

Intelligent silica gel dressing

Technical Field

The utility model relates to a dressing especially relates to an intelligence silica gel dressing.

Background

Scar tissue is a tissue structure that naturally forms during the healing process of a wound. More or less visible scar tissue is formed due to accidents, diseases and after surgery. For example, incisions have been made during operations such as mastectomy, cesarean section, and abdominal plasty, or during accidental injuries such as burns and scalds.

Silicone scar gel film dressings have long been used in clinical procedures for the prevention of scar tissue formation, but have some considerable disadvantages. Conventional silicone gel films cannot be applied to wound tissue because they may cause microbial proliferation of the wound, thereby causing infection, particularly wound tissue in which intact skin has been damaged after surgery. Therefore, the traditional silica gel membrane can only be applied to the wound after healing, or needs longer treatment time, which causes inconvenience to patients and increases the treatment cost of the patients.

Also, the formation of wounds is often accompanied by erythema, congestion and swelling, which can cause severe discomfort to the patient. Ordinary silicone membranes do not improve or alleviate this symptom. In the clinical treatment process, the use of pharmaceutical ingredients such as intelligent ointment, cream and the like in combination with the silica gel film is also tried, but the method is not feasible. First, most of the components of the intelligent cream contain antibiotics or hormonal substances, which can cause allergic reactions in wound tissues and even cause delayed healing of wounds. Meanwhile, the use of the silica gel film can be influenced by the existence of ointment pharmaceutical ingredients, so that the plaster is not firm to adhere, needs to be additionally fixed, and is not favorable for healing of wound surfaces due to frequent replacement of the medicines every day. The existing medical dressing often cannot effectively prevent scar tissues, is complex in structure and incapable of being produced in quantity, and has a lot of inconvenience for patients to use.
