医疗器械外壳是指医疗器械本身的外部保护壳，其主要作用是保护医疗器械内部结构和电路，防止外部物质和杂质进入，同时也可以起到美观和舒适的作用。医疗器械外壳的材料一般选用具有高温、耐腐蚀、抗紫外线等特性的工程塑料或金属材料，常用材料有ABS、PC、PMMA、铝合金等。

The medical device shell refers to the external protective shell of the medical device itself. Its main function is to protect the internal structure and circuit of the medical device, prevent external substances and impurities from entering, and also play a beautiful and comfortable role. The materials used for medical device housings are generally engineering plastics or metal materials with high temperature, corrosion resistance, UV resistance, and other characteristics. Common materials include ABS, PC, PMMA, aluminum alloy, and so on.

医疗器械外壳的设计需要考虑以下因素：

The design of medical device housings needs to consider the following factors:

细节设计：医疗器械外壳需要考虑细节设计，如表面光洁度、壳体厚度、拉手、固定螺丝等，细节设计可以提高产品的外观质量和易用性。

Detailed design: The shell of medical devices needs to consider detailed design, such as surface finish, shell thickness, handles, fixing screws, etc. Detailed design can improve the appearance quality and ease of use of the product.

材料选择：医疗器械外壳的材料选择需要考虑其特性和适用性，如耐高温、耐腐蚀、抗紫外线等，同时还需要考虑材料的成本和可加工性。

Material selection: The selection of materials for medical device housings requires consideration of their characteristics and applicability, such as high temperature resistance, corrosion resistance, UV resistance, etc., as well as the cost and processability of the materials.

结构设计：医疗器械外壳的结构设计需要考虑其与医疗器械内部结构的契合度和固定方式，同时还需要考虑外壳的拆装方便性和维修性。

Structural design: The structural design of the medical device housing needs to consider its compatibility with the internal structure of the medical device and its fixation method, as well as the ease of disassembly and maintenance of the housing.

医疗设备外壳设计的几点要素：

Several elements of medical device housing design:

(1)几何形状和精度。吸塑外壳的几何尺寸包括有：吸塑产品切割面到成型面的尺寸、切割面到切割面的尺寸，它与板材厚度、材料特性、成型工艺有直接的关联。

(1) Geometry and accuracy. The geometric dimensions of the blister shell include: the dimensions from the cutting surface to the molding surface of the blister product, and the dimensions from the cutting surface to the cutting surface, which are directly related to the thickness of the plate, material characteristics, and molding process.

(2)脱模角度。吸塑模具由脱模角度不同的凹模和凸模构成，通常来说，凹模的脱模角度为0．5o-1o，凸模的脱模角度为2o-5o。

(2) Release angle. The blister mold consists of a concave mold and a convex mold with different release angles. Generally speaking, the release angle of the concave mold is 0.5o-1o, and the release angle of the convex mold is 2O-5o.

(3)外壳圆角。吸塑外壳应当设计成尽量大的圆角，不可设计成尖角并要进行倒角处理，确保吸塑外壳产品的应力适宜。

(3) Shell fillet. The blister shell should be designed with a rounded corner as large as possible, and cannot be designed with sharp corners. Chamfering should be performed to ensure that the stress of the blister shell product is appropriate.

(4)宽深比。医疗设备外壳吸塑产品的宽深比是衡量吸塑成型难易程度的重要指标，表示的是产品的小宽度与深度的比例，其值越大表明吸塑产品成型越容易，其值越小则表明吸塑产品成型越难。

(4) Aspect to depth ratio. The width-to-depth ratio of a blister product for a medical device shell is an important indicator of the difficulty of blister molding, indicating the ratio of the small width to depth of the product. A larger value indicates that the blister product is easier to mold, while a smaller value indicates that the blister product is more difficult to mold.

总之，医疗器械外壳是医疗器械中不可或缺的组成部分，其设计需要综合考虑产品的功能、美观、易用性等多个方面，选用合适的材料和加工工艺，以满足医疗器械的使用要求和市场需求。更多相关内容就来我们网站http://www.metferro.com咨询！
