Description

Artificial nose

Technical Field

The utility model relates to a nose mask.

Background

The prosthesis was initially used by patients with limb or organ disabilities. At present, along with the higher acceptance of people on micro-plastic, the use of the prosthesis to improve the self image becomes more and more fashionable. Humping the nose is a common plastic approach. However, in the actual use process, the nose humping is an operation for improving the appearance of the nose by filling the nose with autologous or allogeneic tissues or tissue substitutes to cushion the external nose. Because the filling requires surgery, and the filled tissue cannot be easily replaced, there is also a health risk after long-term use, and thus, the existing nose augmentation methods cannot be completely safe. Moreover, once the hump nose is finished, its shape is fixed and cannot be easily changed.

The artificial nose can be used as a model of the artificial nose to simulate the effect of the artificial nose, so that a user can change different artificial nose effects to determine the nose type.

The nose mask has the following effects: 1. by mixing colors of the flexible photosensitive material and multi-layer covering type photocuring, the natural transition of the color of the prosthesis can be realized, and the simulation effect is achieved. 2. The prosthesis in the utility model does not need a mould when being manufactured, thereby accelerating the process and saving the cost. 3. The color difference can be continuously adjusted in the layered photocuring process, and the defective rate is eliminated. 4. The production cycle required only 3 days and each adjustment required only 2 minutes. 5. The photosensitive material has a low density and an optional fill factor in the initial printing further reduces weight.

Detailed Description

As shown in fig. 1 and 2, a nose prosthesis 100 comprises a dressing layer 101, a middle layer 102 and a surface layer 103. The adhesive garment layer 101 is used for contacting with the skin of a human body; the intermediate layer 102 is arranged on one surface of the clothing layer 101; the surface layer 103 is disposed on the surface of the intermediate layer 102, and the intermediate layer 102 is located between the garment layer 101 and the surface layer 103. The hardness of the dressing layer 101 is lower than the hardness of the intermediate layer 102 and/or the surface layer 103. The shore hardness of the adhesive layer 101 is 0-15HD, and according to the acceptable or favorite degree of a user, the shore hardness of the adhesive layer 101 can be selected to be proper within the range, such as 1HD, 3HD, 6HD, 8HD, 11HD, 13HD and 15 HD. The shore hardness of the middle layer 102 is 15-20HD, and 15HD, 16HD, 17HD, 18HD and 20HD can be selected in the range according to the preference degree of a user. The shore hardness of the surface layer 103 is 20-30HD, and the hardness of the surface layer 103 can be selected within the range to achieve favorable visual effects, such as 20HD, 23HD, 26HD, 27HD, and 30 HD. The adhesive layer 101, the middle layer 102 and/or the surface layer 103 are two-component room temperature curing human silica gel.
