The heteromorphic hydrogel functional dressing provided by the utility model has good biocompatibility and has no stimulation or sensitization to skin; the wound healing situation can be directly observed through the dressing as hydrogel has good transparency; besides, a wet environment for facilitating wound healing can be provided, so that the adhesion of the wound is avoided, scar hyperplasia is alleviated, and the wound healing is accelerated.
Description
Technical Field
The utility model relates to a special-shaped hydrogel functional dressing.
Background
In various burns and scalds, the proportion of the injured hand parts is large, and as the muscles and nerve tissues of the hand parts are the most precise, scars and scar contractures caused by the burns and scalds can affect the hand shapes by light persons, cause ugly appearances and completely lose the functions of the heavy persons. The healing process of the wound surface of the hand burn and scald is also the process of the wound surface forming new tissues and epidermal growth, and clinical application proves that the timely rehabilitation auxiliary treatment in the healing process of the wound surface can most effectively relieve scars, tissue adhesion and muscle contracture. At present, no wound nursing product which is suitable for wound nursing of hand burns and scalds and can realize function rehabilitation auxiliary treatment is reported in China. In the nursing of burn and scald wounds of hands, bandages or other sheet dressings are generally used for bandaging, and in order to avoid muscle contracture and joint stiffness of the burn and scald wounds of hands in the healing process of the wounds, the hands are usually fixed by the aid of other instruments. The main means for treating and recovering hand functions are massage and functional exercise through equipment. Since massage can only be performed after the wound surface is healed to a certain extent, passive massage therapy cannot perform functional exercise in time. At present, the rehabilitation equipment for hands mainly comprises elastic gloves, elastic balls and other similar products, the equipment is mainly made of plastic or silica gel, and due to the fact that the surface of the equipment is dry, if the equipment is directly used for the hands with unhealed wound surfaces, the wound surfaces of the hands can be adhered to the equipment, secondary damage is caused to the wound surfaces, and therefore the equipment can only be used after skin is completely healed, and functional rehabilitation auxiliary treatment cannot be timely carried out on the hands.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a special-shaped hydrogel functional dressing which can be applied to wound surface nursing and functional rehabilitation auxiliary treatment of hand burns and scalds.
The utility model provides an above-mentioned technical problem's technical scheme as follows: a special-shaped hydrogel functional dressing comprises a hydrogel functional dressing body, wherein the hydrogel functional dressing body is spherical or hemispheroid in shape, and the surface of the hydrogel functional dressing body is smooth or provided with a bulge; wherein,
the diameter of the hydrogel functional dressing body is 50-250 mm;
the number of the bulges is 5-100, and the bulges are uniformly distributed on the surface of the hydrogel functional dressing body.
The utility model has the advantages that: the material of the special-shaped hydrogel functional dressing of the utility model is medical hydrogel, which has good transparency and can directly observe the wound healing condition through the dressing; has good biocompatibility, no stimulation to skin and no sensitization; can provide a wet environment for promoting wound healing, does not adhere to the wound, reduces scar hyperplasia and accelerates wound healing; mechanical strength is moderate, can fix disease hand shape, avoids the adhesion of hand tissue, and to its gripping through patient's hand, realize the recovered adjunctie therapy of hand function, the prevention hand joint stiffness and muscle contracture realize the surface of a wound healing and function recovery and go on simultaneously, are showing the treatment that improves the hand burn and scald.
On the basis of the technical scheme, the utility model discloses can also do following improvement.
Further, the bulge is a hemisphere with the diameter of 1-10 mm or a cylinder with the diameter of 1-10 mm and the height of 1-10 mm; other shapes that maintain the functional position of the burned hand by grasping the dressing are also possible.
Further, the special-shaped hydrogel functional dressing is prepared from 5-70% by mass of a hydrophilic high-molecular polymer aqueous solution.
