The invention relates to the technical field of medical cold compress tools, in particular to a conformable surface cold compress rehabilitation device based on a 3D printing system.
Background
3D printing is typically achieved using digital technology material printers. The SLS (powder sintering) is one of the processes in 3D printing, and the SLS printing technique adopts powder spreading to spread a layer of powder material on the upper surface of a molded part and heat to a certain temperature just below the sintering point of the powder, and a control system controls a laser beam to scan the powder layer according to the cross-sectional profile of the layer, so that the temperature of the powder is raised to a melting point, and sintering is performed and bonding is realized with the molded part below. After one layer is finished, the workbench descends by one layer, the material spreading roller spreads a layer of uniform and dense powder on the material spreading roller, and the sintering of the section of a new layer is carried out until the whole model is finished. Advantages of SLS: firstly), the SLS can be made of more materials, including various powders such as high polymer, metal, ceramic, gypsum, nylon and the like; second), precision, now the precision is normally made to a tolerance of plus or minus 0.2 mm. And thirdly), without support, it needs no support structure, and the suspended layer generated in the lamination process can be directly supported by the unsintered powder. Fourthly), the utilization rate of the material is high, and the utilization rate of the material is high. Because do not need to support, need not to add the base, for material utilization is the highest among several kinds of common 3D printing techniques, and the price is cheap relatively.
The ice compress is used as a clinical common ice bag for cooling a patient, and the principle is to reduce and slow down the release of histamine and reduce the sensitivity of tissues to pain; reducing the exudation and swelling of the circulation and surrounding tissues; reducing the effects of vascular endothelial cells and thrombus formation; decrease the release of oxygen radicals, and the like.
The problems existing at present are as follows:
1. currently, it is a clinical practice to wrap the ice bag with a towel and then place the ice bag at a position of a patient where ice compress is needed. However, in this way the ice bag is easily detached.
2. After the joint operation, only the two sides of the joint are iced, and the ice bag cannot be in full-dimensional close contact with soft tissues, so that the iced effect is influenced.
3. The ice in the ice bag is solid, the ice bag is made of plastic, the solid ice can easily puncture the bag, so that solution in the ice bag leaks, water after ice cubes are melted can permeate out of a towel or fine cloth and drip on the skin of a user, and secondary injury can be caused to a patient seriously.
4. The ice blocks or the ice bags are hard and stiff and can not be completely attached to the human body according to the joint curvature, so that the corresponding ice compress effect can not be achieved;
5. the ice bag is fixed by a towel, and a patient has to use hands to assist the ice bag to fix, so that the body position of the patient is limited and the patient cannot move.
6. Blood vessels of human arms are distributed along the longitudinal derivation of the arms, and the ice bags are pressed on the skin in a whole block, so that the skin is not buffered, and the blood vessels are necrotized for a long time.
