Description

Protection system for accelerating recovery of burns and scalds Technical Field The invention relates to the technical field of medical equipment, in particular to a protection system for accelerating recovery of burns and scalds. Background The skin is the biggest organ of human body, can protect human internal tissue from bacterial hazard, and the wound that causes by surgery, wound and superficial burn etc. needs to be wrapped with dressing in order to prevent bacterial invasion, thereby avoid the wound inflammation to accelerate wound healing process, wherein burn and scald is more easy to infect, recovery time is longer than other types of wound, is a wound that is great to skin damage. The severity of the burn is dependent on the extent and depth of the injured tissue, and the burn depth can be divided into degree I, degree II and degree III. The first degree burn injury is the least. Burn skin redness, pain, apparent tenderness, exudation or edema. The injured part was partially whitened by light pressure, but no blister was present. The II degree burn injury is deeper. The skin has blisters. The blister bottom is red or white and filled with a clear, viscous liquid. Tenderness and whitening upon compression. Degree III burn injury is the deepest. The burn surface may be whitish, soft or black, carbonized leather-like. The burned skin becomes pale, and is often mistaken for normal skin in white skin people, but does not discolor when pressed. The destroyed red blood cells can make the burned local skin appear bright red, occasionally have blisters, the hair of the burned area is easy to be pulled out, and the sense is reduced. The wound dressing is widely applied to the surface of scalds, burns, ulcers or other traumated skin, has temporary protection and treatment effects on the damaged part of the skin, can protect the wound from exogenous pollution such as bacteria and the like and promote wound healing. The wound dressing has the action mechanism of protecting the wound from exogenous pollution by absorbing wound exudates, and providing a favorable environment for the wound surface, thereby promoting wound healing. The ideal wound dressing should have good biocompatibility, be able to provide a moist environment for the wound, allow gas exchange, protect the wound from microorganisms such as bacteria, and be non-toxic and non-allergenic. In the prior art, as proposed in the patent document with the publication number of CN103893815B, the scald and burn dressing is a nanofiber membrane with a core/shell structure, the shell is made of natural biological polymer materials, the core is made of degradable synthetic polymer materials loaded with astragaloside, and the mass ratio of the astragaloside to the degradable synthetic polymer materials is 1:2-50. The prior art can utilize the electrostatic spinning technology to prepare the dressing for treating the burn and scald wound, but has the defects that the dressing is prepared in advance through the corresponding electrostatic spinning device, the equipment for directly treating the burn and scald wound is not involved, the fiber dressing prepared by the prior device needs to be subjected to secondary packaging and storage, the labor and space cost are consumed, the best treatment effect of the dressing is not beneficial to the dressing, growth factors in the fiber dressing or other treatment factors which are beneficial to the healing of the burn and scald wound can gradually lose activity in the long-time storage process, the healing promoting effect of the fiber dressing on the burn and scald wound is also reduced, the healing time is prolonged, and the infection and inflammation preventing effects on the burn and scald wound by utilizing the dressing can be influenced. Furthermore, since the inventors herein have studied numerous documents and patents, on the one hand, and have not set forth in detail all the details and content of the invention for the purpose of understanding the differences to those skilled in the art, on the other hand, the invention is by no means lacking in the features of the prior art, but rather the invention has all the features of the prior art, and the applicant retains the right of the prior art in the background of this invention. Disclosure of Invention Aiming at the defect that the medical effect is lost due to the fact that secondary packaging and preservation are needed for the fiber dressing manufactured by the technical scheme provided by the prior art, the application provides a protection system for accelerating recovery of burns and scalds, which is characterized by comprising a bearing mechanism, a wire outlet mechanism, a monitoring module and a control module, wherein the bearing mechanism is used for providing a lying environment for a patient suffering from burns and scalds, the wire outlet mechanism is used for coating spinning stock solution at a burn and scald wound surface in a fiber dressing mode
