The invention discloses a biological patch material with dry-state adhesion and wet-state easy stripping characteristics and application thereof, and belongs to the field of biological medicine. The biological patch material is prepared according to the following steps: by taking water-soluble protein as a template and copper ions in water-soluble copper salt as a metal coordination center, carrying out self-assembly on the template and drug molecules with phenolic hydroxyl structures to form nanoflowers; mixing the acrylamide, the sodium alginate, the water-soluble calcium salt and the nano-flowers to obtain the water-soluble calcium-based water-soluble nano-flower fertilizer. The biological patch material is adhered to the skin through electrostatic interaction, covalent bonds, physical interpenetration and topological tissues. The patch has skin adhesion in a dry state, so that the patch is convenient to fix; after the patch is in contact with burnt skin, the patch absorbs water and swells, the adhesive force is obviously reduced, and painless, easy and non-invasive stripping is realized. In addition, the patch has immunoregulation performance, can prevent stimulation and anaphylaxis caused by long-term contact with the skin, and promotes burn repair.

The invention discloses an application device for burn wound repair, and belongs to the technical field of burn application equipment.The application device comprises a body surface application layer, a reagent limiting and releasing layer and a medicine storage layer, the body surface application layer is tightly attached to burn skin, net-shaped small holes are formed in the body surface application layer, the reagent limiting and releasing layer is arranged above the body surface application layer, and the medicine storage layer is arranged above the reagent limiting and releasing layer. The body surface pasting layer is fixedly connected with the reagent limiting and releasing layer, and the medicine storage layer is connected with the reagent limiting and releasing layer. In order to overcome the defects that an existing burn application is inconvenient to change medicine, uneven in medicine absorption, poor in application adaptability and the like, the invention provides the application device for repairing burn wounds, and the problems that secondary trauma is easily caused when a traditional application is replaced, residual medicine affects new medicine effect exertion, and the traditional application is difficult to attach to wounds in different shapes are effectively solved.

The invention belongs to the technical field of skin medicine application devices, and particularly provides a burn skin nursing medicine application device which comprises a housing mechanism, a supporting frame is arranged in the middle of the housing mechanism, a springing type push plate mechanism is slidably arranged in the supporting frame, and an overturning type application mechanism is rotatably arranged on the springing type push plate mechanism; according to the medicine application device for burn skin care, ventilation drying and continuous moisturizing application can be achieved, the pre-acting principle is adopted, ventilation and sealing of the inner space of the supporting frame are controlled through the ventilation mechanism, ventilation of an affected part is kept during cold compress, and accumulated water, moisture and skin frostbite are avoided; moist application is kept during medicine application, water loss is reduced, the medicine effect is guaranteed, healing is accelerated, and the infection risk is reduced; in addition, a wearable structure is combined with an elastic push plate mechanism, so that dressing change operation is simple, and the use convenience and comfort of the patient are improved.

This invention discloses a method for assessing the recovery degree of burned skin based on skin image recognition. The method includes: acquiring visible light and infrared thermal images of a patient with a skin burn, preprocessing them, and fusing them into a skin burn image; performing feature extraction, recognition, and segmentation to obtain an image of the burn area; constructing a static feature set based on burn feature parameters, and constructing a three-dimensional model of the burn wound based on the burn area image and depth image to construct a dynamic feature set; inputting the extracted static and dynamic features into an optimized deep learning-support vector machine fusion model for training, performing final classification of the recovery stage, and calculating the time required for complete healing. The method provided by this invention can not only effectively capture the static feature information of the burn area, but also dynamically monitor the recovery trend of the wound in real time and accurately predict the time required for complete healing, significantly improving the accuracy and personalized assistance of burn diagnosis and treatment.

The invention relates to a mechanical arm control technology, and discloses a path planning method of a mechanical arm for massaging burnt skin, which comprises a pressure control module, a path planning module, a motor driving module and an error correction module. The pressure control module and the motor driving module achieve control over pressure and the pose of the mechanical arm through closed-loop design, and the precision and the anti-interference capacity are improved. The path planning module uses an RANSAC algorithm and mechanical arm pose requirements of discrete path points obtained through path fitting to obtain inverse kinematics through a numerical method, and the rotation angle of each motor is obtained; the error correction module achieves smooth and stable operation of the mechanical arm through methods such as PID control. Through the combination of the modules, the mechanical arm can automatically massage a burnt part, and the mechanical arm can replace part of the requirement for manual massage due to burn, and has a good medical instrument application prospect.

The invention discloses a high-frequency nevus removing device based on medical laser, relates to the technical field of laser nevus removing instruments, and provides the following scheme that the high-frequency nevus removing device comprises a laser nevus removing instrument body, the laser nevus removing instrument body is provided with a laser head, a bracket is installed on the side wall of the laser head, a clamping block is inserted into the bracket, and a sliding rod is slidably connected to the clamping block; a mounting rod is inserted into the bottom end of the sliding rod, a guide wheel is rotationally connected to the bottom end of the mounting rod, a cotton thread is wound around the guide wheel, a suction pipe is mounted on the mounting rod and communicates with one end of the cotton thread, the laser head is connected with an abutting ring, and a smoke inlet hole is formed in the inner side of the abutting ring; by pressing the pressing rod, the cotton thread at the tail end of the guide wheel abuts against the skin at the burning position, and when the motor works, the cotton thread is driven to move to wipe the burnt skin, so that whether the burnt skin is completely removed or not is conveniently determined, smoke can be pumped away when generated, normal saline is applied to the cotton thread to wet the wiped cotton thread, and the wiping effect is improved. The scorched skin can be conveniently removed, and friction stimulation is reduced.
