The utility model provides a one-piece open-ended toe protector, as shown in figure 1 and figure 2, which is used for protecting and curing toes of patients with toe paronychia. This protective equipment passes through 3D printing technique, prints the generation after scanning patient's toes with the generative model to guarantee this protective equipment can with the perfect laminating of patient's toes. The protector is arched, can cover the upper side, the front side, the left side and the right side of the toes and does not cover the lower side of the toes, so that a patient can walk conveniently. Then the gauze coated with the gel-state dressing is pasted on the position of the inner wall of the protective clothing, which corresponds to the affected part of the patient.

The preparation and use of the protector are described below with reference to the examples.

Examples

S1, using Geomagic Studio, Materialise Magics and other software to complete the design of the protector, the steps include: the method comprises the following steps that a 3D foot type scanner is used, a laser scanning technology is adopted, a patient stands for about 2 minutes on a foot scanner workbench, a laser scanning head rotates around the foot for a circle, data collection can be completed, and a foot model is automatically established; adopting a computer aided design technology, firstly, importing a foot model of a patient; realizing model repair, so that a foot model structure established by a foot scanner has no break point; at the minimum position of the diameter of the root of the toe, a plane perpendicular to the foot is cut and created by using a plane, and the toe model is cut out, so that the toe can be fixed in the protective tool, and the protective tool is prevented from slipping off when in use; then selecting a position 4mm above the bottom surface of the toes as a horizontal tangent plane, dividing the toe model into an upper part and a lower part, and deleting the part below the tangent plane, namely deleting the corresponding section at the lower side of the toes to preliminarily form an arch-shaped mold; a carving knife with a polygonal interface is adopted to form a groove with the thickness of 1mm between the affected part and the position of the protective clothing corresponding to the affected part, and the groove is used for filling a dressing layer 4 in the subsequent step, wherein the dressing layer 4 is a gauze piece coated with gel-state dressing in the example; then, fast smoothing is carried out to eliminate uneven parts formed by the operation of the graver; in some embodiments, under the condition of ensuring that the protector has enough strength, the toe tip is avoided, the air holes 3 are designed on the toenail cover and the surrounding affected part to ensure the ventilation of the affected part and prevent the deterioration, in the embodiment, 8-20 air holes 3 are arranged, the radius of the air holes 3 is 2mm, and the stability of the protector is ensured while the ventilation is ensured; forming a 3D printing model and then printing; the 3D printing material is nylon or resin, and the two materials are light, cheap and sufficient in strength; the thickness of the protective tool is set to be 2-2.5mm, and the protective tool is small in size and convenient for a patient to wear shoes; the edge of the protective clothing is divided into a lower edge 1 and a rear edge 2 which are both provided with curved surface fillets and used for enabling the inner surface and the outer surface of the protective clothing to be connected smoothly so as to reduce the friction and the injury of the protective clothing to the toes.

S2, mixing the PBS buffer solution and a silver ion antibacterial agent (Fuhuotai) according to a ratio of 1:1 to serve as a solvent, and adding poloxamer F-127 temperature-sensitive hydrogel powder to enable the poloxamer F-127 temperature-sensitive hydrogel powder to account for 20% of the mass of the mixed solution; the solution is in a liquid state at a low temperature of 4 ℃ and can be solidified into a gel state at normal temperature, so that the solution is well sealed after preparation is finished and is placed in a refrigerator for refrigeration; the PBS buffer solution not only has a buffering effect on pH, but also has a salt balance effect on NaCl and KCl contained in the PBS buffer solution, so that the affected part can be recovered under a proper condition.

S3, as shown in figure 2, soaking the solution with 4-6 layers of gauze pieces, and then sticking the gauze pieces to the grooves; the solution is gradually solidified at room temperature, and a gel-state dressing layer 4 is formed outside the gauze piece; the affected part after the operation of the patient can directly contact the dressing after being disinfected conventionally; when the patient uses the protector, the protector can be conveniently taken out, the protector is cleaned according to the recovery condition of the affected part, the inner-layer dressing is prepared again according to the process, and the dressing is changed for one time in 3-5 days under the general condition; if the affected part is infected or has bleeding, the dressing should be changed frequently; the gel soft dressing can slowly release and resist bacteria, reduce impact and friction and improve wearing comfort.
