• Biocompatibility and Material Safety: All components in contact with the medication or skin must comply with ISO 10993 for biological safety.
• User Indication and Safety: Devices must clearly indicate when they are ready to inject and when a dose has been delivered, reducing the chances of misuse.
• Prevention of Premature Actuation: Design must prevent unintentional firing to protect both the user and the patient.
• Durability: Devices are tested for consistency after exposure to varying temperatures, lifetime operation cycles, vibration, shock, and both mechanical and electrical disturbances.
• Sterilization and Hygiene: Components intended to be sterile must undergo validated sterilization procedures.
• Acoustic Limits: To protect patients, maximum sound levels during actuation are specified.
• Clear Instructions for Use: Manufacturers must provide precise instructions, including any warnings if certain criteria (like noise limits) are exceeded.

Who Needs to Comply?

• Manufacturers and suppliers of needle-free injectors for clinical, hospital, pharmacy, and at-home patient use.
• Regulatory and quality assurance personnel in health care device companies.
• Healthcare providers using needle-free injection technologies.

Practical Implications for Implementation

Compliance means following robust design, material selection, testing, and labeling workflows. Manufacturers must ensure traceability and provide clinical data supporting device performance.
