Embodiment 1

[0066] Example 1 3D printing a band-aid that fits the arm

[0067] Step 1: Image recognition and modeling of the wound

[0068] First cut three incisions of different shapes on the pigskin, and use a scanner or smartphone to take pictures of the front of the wound (such as figure 1 shown), wirelessly transfer the photos to the PC. The PC processed the photos sequentially through black-and-white processing, binarization processing, and the eight-connected method to determine the coordinate data of the wound contour, and then imported them into Adobe illustrator (Ai) software. After running the customized Ai plug-in, it automatically traced to generate a two-dimensional vector map of the wound contour. After further importing into Autodesk 3ds max software, the outline size can be appropriately modified, and the extrusion command can be used to generate a three-dimensional model matching the corresponding wound shape (such as figure 2 shown), save it as an STL file and store ...

Embodiment 2

[0079] Example 2 3D printing a Band-Aid that fits fingertips

[0080] Step 1: Scanning and modeling of wound and fingertip

[0081] The scanning modeling process of the wound is basically the same as that of the implementation case 1: firstly, a circular opening is made on the tip of the index finger of the dummy mannequin. Use a smart phone to take photos of the front of the wound, and run the customized Ai plug-in to automatically trace to generate a two-dimensional vector map of the wound outline. After further importing into the Autodesk 3ds max software, the outline size can be modified appropriately, and the three-dimensional model can be generated with the extrusion command, saved as an STL file format and stored in the SD card for printing. Scanning and modeling process of the injured part: Use a smart phone to take photos of the injured index finger. The photos taken are superimposed and converted into stereoscopic images through image converters and transmission con...

Abstract

The invention belongs to the field of hygienic products, and particularly relates to a preparation method of a 3D printed wound customized adhesive bandage matched with the size, the shape and the injured part of a trauma wound through 3D printing. The wound customization program comprises image information acquisition of a wound shape and an injured part, computer image recognition and modeling to generate a model file to match the shape, the size and the injured part of the wound; and performing 3D printing on the model file to generate the adhesive bandage base material. The adhesive bandage base material can integrate one or more functions of antibiosis, blood coagulation, moisturizing, ventilation, inflammation diminishing and the like so as to accelerate wound healing. The 3D printedwound customized adhesive bandage provided by the invention can be attached to different injured parts, and can be matched with the outline and the size of a wound. The adhesive bandage is adjustablein shape, accurate in medicine application, simple to manufacture, convenient and rapid, and particularly suitable for accurate treatment of traumatic wounds of different shapes and different parts.

Description

technical field [0001] The invention belongs to the field of hygienic products, and in particular relates to a preparation method of a 3D printed wound-customized wound plaster that fits the size and shape of a traumatic wound and a wound site. Background technique [0002] The skin is the largest organ of the human body and the primary barrier to isolate the internal environment of the human body from the external environment. Wounds (especially surgical wounds) are the rapid response of the human body to skin injuries such as cuts and tears. Adopting effective diagnosis and treatment measures is crucial to reduce the mortality and morbidity rate caused by wound infection: effective and timely wound treatment can make it heal quickly; Systemic infection, life-threatening. Using a wound dressing is an effective way to manage a wound. As a mature commercial wound dressing product, medical band-aid can play the basic functions of anti-inflammation, hemostasis and wound prot...
