Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a biological adhesive coating device for preparing artificial skin.
Background
The skin defect refers to skin loss caused by burn, scald, mechanical injury, etc. If the damage depth of the skin defect part reaches the dermis and below, the human body can not be completely regenerated, but heals by the fibroblast growing-in mode and the like, scar tissue is formed at the defect part after healing, the color and the shape of the scar tissue are greatly different from those of normal skin, and the scar tissue is extremely unattractive, so that psychological burden is easily brought to patients; moreover, scar tissue has poor elasticity, lacks pores, has poor air permeability and is easy to cause discomfort for patients. Therefore, skin should heal as normally as possible to avoid scar tissue when treating skin defects.
Clinically, the damaged part is usually repaired by stretching the skin around the damaged part or transplanting the skin of other parts, but when the area of the deep defect part is very large (such as severe burns and scalds), because the number of undamaged parts of a patient is small, the requirement of covering the defect part cannot be met by the obtained normal skin, so the methods cannot be applied. However, because the defect parts are usually different in depth and irregular in shape, and the existing artificial skin has long preparation period and high cost, the artificial skin is usually difficult to achieve an ideal attaching state, so that the treatment effect is not ideal enough.
In order to overcome the defects of the artificial skin, the concept of treating a wound surface by using biogel is generated in the prior art, the biogel is a novel medical product, has the characteristics of antibiosis, infection resistance, degradation, absorption, acceleration of cell growth, rapid hemostasis, pain relief and the like, and has a wide application range in the medical field.
When large-area skin injury is treated, a layer of biological glue is applied to the scalded wound surface, so that the healing of the wound surface can be effectively accelerated, and the scalded wound surface can automatically fall off after the wound is healed. The biological glue can quickly stop bleeding, reduce the exudation of blood of a wound, provide an optimal moist environment for the healing of a burn wound and prevent the formation of scars.
However, current biological glue coating, mostly crowd skin injury department through medical personnel's manual with biological glue, then even is paintd with biological glue through the cotton swab to rethread cotton swab, like this when painting biological glue, not only partly biological glue can be taken away to the cotton swab, when carrying out the skin injury treatment of large tracts of land, need use a lot of cotton swabs, increase medical personnel working strength, and the cotton swab still can produce the stimulation to the wound part, cause the patient to be uncomfortable, and paint through the manual work, cause very easily and paint inhomogeneously, the nursing effect that leads to skin injury is not good, and hardly master and paint the dose, and skin injury face exposes outside for a long time, arouse the infection risk easily.
