Under the voltage status different compared to A, B, C, middle 3.3V, 3.4V, 3.5V, voltage is bigger(Ultraviolet ray intensity is bigger), i.e. table Show under the intensity of illumination of different ultraviolet lights, identical irradiation time, illumination colors are deeper;
Therefore, the color and variation presented according to different light application times, the adjustable emulation epidermis of intensity of illumination.
In order to make the structure for emulating epidermis closer to human body or can be attached on simulation architecture, can be placed in mold Simulation architecture, such as simulation skeleton can touch simulation skeleton in body surface so that the planform of basal layer 3 is changeable, be medico It carries out providing bony landmark when treatment operation, to meet the needs of different.As shown in Fig. 2, emulation knot is placed in mold in advance Structure 4, specific preparation method include:
A) basal layer 3 is prepared:Mixed liquor C is configured, by 6016 two-component liquid-state silicon gels with 6016A component and 6016B component with 10: 1 ratio is sufficiently mixed, and is added in the mold for placing simulation architecture 4 in advance, to be solidified;
B) skin layer 2 is prepared:Mixed liquid B is configured, by 8608 two-component liquid-state silicon gels with 8608A component and 8608B component 1:1 After ratio is sufficiently mixed, it is added to the mold with basal layer 3, it is to be solidified;
C) epidermis 1 is prepared:Mixed liquor A, including 8608 two-component liquid-state silicon gels and ultraviolet color changing powder are configured, wherein 8608 pairs of groups Part liquid-state silicon gel is by 8608A component and 8608B component with 1:1 ratio mixing, ultraviolet color changing powder weight are 8608 two-component liquid After being sufficiently mixed, mold is added in the 1% of state silica gel weight, to be solidified;
In order to preferably simulate human body complexion, in the above preparation method, can also be prepared in epidermis 1 and/or skin layer 2 Toner is added in journey into mixed liquor A and/or mixed liquid B, wherein the weight of toner can be the 0.05%- of liquid-state silicon gel weight 2.5%。
In the above-mentioned methods, mixed liquor A, B, C in the curing process, combine closely between adjacent layer, are integrally formed, and have Toughness, tear-proof, are not susceptible to lamination under external force.
Due to the difference of human body, the imitative of different-thickness can also be formed by controlling the weight of every layer of liquid-state silicon gel True epidermis, with the simulation closer to human body real skin.
Embodiment two:
As shown in Figure 3, Figure 4, the simulation model applied to cupping training comprising the emulation of emulation epidermis, support emulation epidermis Structure 4 and Electronic cupping jar 5 for operation,
Wherein emulation epidermis includes:
Epidermis 1 with ultraviolet color changing powder:With a thickness of 2mm, shore hardness HA20, by 8608 two-component liquid-state silicon gels, purple Outer color-change powder, toner curing molding, wherein 8608 two-component liquid-state silicon gels are by 8608A component and 8608B component with 1:1 ratio Mixing, ultraviolet color changing powder weight are the 2% of 8608 two-component liquid-state silicon gel weight, and toner weight is 8608 two-component liquid-state silicon gels The 2% of weight;
