What are the standards for medical device casings? In the medical device industry, the cases serve as the first line of defense for products, and its customization standards directly affect the quality, safety, and user experience of the product. This article discusses material selection and geometric shapes.

The core standards for customizing medical device casings are elaborated in detail in terms of shape and precision, structure and functional design, surface treatment and labeling, as well as packaging and transportation. The aim is to provide comprehensive and professional guidance for the industry and promote medical care standardization and standardized development of customized instrument casings.

1. Material selection criteria

The selection of materials for medical device casings must strictly comply with relevant regulatory requirements, ensuring that the materials have good biocompatibility, corrosion resistance, high temperature resistance, and mechanical strength. For medical devices that require a sterile state, the shell material also needs to have excellent antibacterial performance. Common materials include plastics (such as PC, ABS, PC/ABS alloys, etc.) and metals (such as stainless steel, titanium alloys, etc.). When selecting materials, it is necessary to fully consider the product's usage environment.

Ensure that material performance matches product requirements based on functional requirements and cost factors. For example, for portable monitoring products, handheld ultrasound, etc., it is recommended to use PC materials with a fire rating of V2 or above or ABS+PC materials to meet fire and machine requirements. For desktop or wheeled products, it is recommended to use ABS material with a fire rating of V2 or higher to reduce costs and meet general usage needs.

2. Geometric shape & accuracy standards

The geometric shape of the medical device casing must meet the product design requirements to ensure assembly accuracy and ease of use. During the customization process, it is necessary to strictly control the geometric dimensions of the shell, including the dimensions from the cutting surface to the forming surface, and from the cutting surface to the forming surface.

The dimensions of the cutting surface are directly related to the thickness of the board, material properties, and forming process. At the same time, factors such as demolding angle, shell fillet, and aspect ratio need to be considered to ensure the forming quality and stress distribution of the shell the fabric is suitable. The demolding angle is an important parameter in mold design, usually ranging from 0.5-1°C for concave molds and 2-5°C for convex molds. The rounded corners of the shell should be designed to be as large as possible, avoiding sharp corner designs to reduce stress concentration. The aspect ratio is an important indicator for measuring the difficulty of vacuum forming, and the larger its value, the easier it is to form vacuum formed products.

3. Structural & functional design standards

The structural design of medical device casings should fully consider the functional requirements and ease of use of the product. The shell should have good sealing, waterproof, dustproof, and impact resistance to protect internal components from external environmental influences ring. At the same time, the ease of disassembly and maintenance of the casing should also be considered to facilitate the repair and maintenance of the product. In terms of functional design, the shell needs to coordinate with the product's operating interface, display interface, and other components to ensure that users can operate the product conveniently and intuitively. For example, the layout of the operating interface should follow ergonomic principles, and high-frequency function keys should be placed within the natural gesture radius of the operator; The color temperature of the display interface should be controlled within the range of 5000-6000K comply with medical display requirements.

4. Surface treatment & labeling standards

The surface treatment of medical device casings is of great significance for improving the aesthetics, corrosion resistance, and antibacterial performance of products. Common surface treatment techniques include polishing, spraying, electroplating, etc. When choosing surface treatment techniques, it is necessary to fully consider the characteristics of the material and the usage environment of the product to ensure that the treatment effect meets the product requirements. At the same time, clear and accurate product information, including production date, expiration date, batch number, manufacturer, etc., should be marked on the shell.

These information should be identified in a wear-resistant and easily recognizable way for users to query and trace.

5. Packaging & transportation standards

The packaging of medical device casings must comply with relevant regulatory requirements to ensure that the products are not damaged during transportation and storage. Packaging materials should have good physical protection performance, chemical stability, and environmental adaptability, and be able to withstand protect the product from external pressure and impact to prevent damage. At the same time, the packaging also needs to have good sealing to prevent microbial invasion and ensure the sterile state of the product. During transportation, appropriate protective measures should be taken, using shock-absorbing materials, fixing devices, etc. to reduce the vibration and impact on the product. In addition, it is necessary to label the packaging, including fragile, moisture-proof, sunscreen and other warning signs indicate signs to facilitate proper handling of products by transportation personnel.

Conclusion

The customized standard for medical device casings is an important cornerstone for ensuring product quality and improving industry standards. By establishing scientific and reasonable customization standards, it is possible to ensure the material selection, geometric shape and accuracy, and structure of medical device casings. The structure and functional design, surface treatment and labeling, as well as packaging and transportation, all meet relevant requirements, providing users with safe, reliable, and convenient medical device products. In the future, with the continuous advancement of technology and the development of the industry, the customization standards for medical device casings will be continuously improved and optimized, providing strong support for the healthy development of the industry.
