The present application relates to the technical field of medical apparatus and instruments, in particular to a general surgery incision recovery nursing device, which comprises a covering frame ring, the inside of the covering frame ring is provided with a covering control assembly, the covering control assembly comprises an assembly sliding groove which is arranged on the upper part of the inner side of the inside of the covering frame ring, a covering gauze layer is fixedly installed inside the two ends of the covering frame ring, one end of the covering gauze layer which is close to the middle position of the covering frame ring is fixedly installed with an assembly sliding rod, the front and rear ends of the assembly sliding rod are both fixedly installed with an expansion pull wire, the inside of the front and rear ends of the expansion pull wire is both provided with a penetrating hole, and the inside of the penetrating hole is movably provided with a contraction pull wire. The covering control assembly can adjust the sealing and air permeability effect of the incision according to the nursing needs of the incision, the size, position and recovery speed of the wound of each patient can be different, the structure design allows medical staff to make personalized adjustment according to the specific condition of the patient, and the best nursing effect is ensured.

The utility model discloses a local wound of face's sub -parent formula pressurization bandaging device for wound bandaging technical field, including sub -bottom plate and parent bottom plate, and the two side surfaces of sub -bottom plate and parent bottom plate are face skin surface and tensile band adhesion surface respectively, and face skin surface is provided with the mucilage that can be fixedly attached to patient's face, and the tensile band adhesion surface of sub -bottom plate and parent bottom plate is fixedly provided with a plurality of sub -tensile band and a plurality of parent tensile band respectively, every sub -tensile band can be connected with corresponding parent tensile band and is independently adjusted tightness, to press tightly fixed in the wound position with the dressing arranged between two tensile bands and skin, and ensure that local pressure is in the preset pressure range, sub -bottom plate can be tailor along the extension direction of sub -tensile band, and parent bottom plate can be tailor along the extension direction of parent tensile band, so that the size of sub -bottom plate and parent bottom plate and the number of sub -tensile band and parent tensile band are matched with the size of wound, realize local accurate pressurization bandaging.

The application discloses a medical debridement nursing device and relates to the technical field of medical debridement, which comprises an ultrasonic debridement machine body, a mounting rack is fixedly connected to the top of the debridement machine body, and a mounting ring is arranged on the mounting rack. The radial self-adaptive adjusting structure composed of a transmission plate, a transmission groove, a transmission column and a transmission pipe can automatically drive a plurality of water absorption pipes to gather towards the center according to the size of a wound, realizes self-adaptive surrounding and adhesion to wounds of different sizes, and simultaneously cooperates with a water absorption mechanism formed by a medical-grade diaphragm vacuum pump to form stable negative pressure on the transmission pipe through a second hose, a water absorption ring pipe and a third hose. After a medical staff member flushes a wound with a cleaning gun head, sewage flowing around the wound is quickly absorbed into the sewage tank through the water absorption pipe, and the medical staff member does not need to manually clean the sewage in the whole process, thereby effectively preventing the sewage from polluting the clothes of a patient and an operation table and significantly improving the cleanliness and work efficiency of debridement operation.

This invention discloses a portable intelligent wound measurement method and system based on the fusion of Hough circle transform and deep network, belonging to the field of artificial intelligence medical image processing. The method includes the following steps: acquiring wound images containing circular calibration objects and ensuring standardized image capture through a pose awareness mechanism; performing feature enhancement and preprocessing on the images; anchoring the calibration objects using an adaptive parameter Hough circle transform algorithm and obtaining pixel radii to establish a spatial scale; inputting the images into a pre-trained U-Net++ deep semantic segmentation network, extracting features using dense skip connections, and outputting a binary segmentation mask of the wound surface; finally, retrieving the true area and size based on the mask features and the scale. This invention uses a deep network to extract the wound surface and combines it with Hough circle transformation for scale fixation and pixel calculation, effectively improving the segmentation accuracy and measurement accuracy of complex wounds, achieving automated quantification of wound size and area, reducing manual measurement errors, and improving the efficiency of wound assessment and management.
