Hand-held Device for Local Piercing of Human or Animal Skin, Drive Module, Needle Module and Method for Coupling

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a handheld device designed for locally piercing human or animal skin, particularly for applications like injecting substances, tattooing, or applying permanent makeup. The device is modular, consisting of a drive unit and a needle module, which can be easily and securely coupled and decoupled. The coupling mechanism ensures simple, reliable, and safe connection and disconnection between the drive and needle modules, improving usability and hygiene. The device includes features for precise alignment, secure attachment, and potential for disposable needle modules.

Use CasesContent extracted from patent full text and abstract with AI.

• Professional tattoo machines with enhanced safety and ease of needle replacement
• Devices for medical microinjections, such as drug delivery or vaccinations
• Cosmetic tools for applying permanent makeup (micropigmentation)
• Veterinary tools for injecting medications into animals
• Microneedling devices for dermatological treatments

BenefitsContent extracted from patent full text and abstract with AI.

• Easy and secure coupling/decoupling of needle modules, reducing risk of misuse or contamination
• Improved hygiene due to potential use of disposable needle modules or parts
• Minimized user error through mechanical guidance and alignment features
• Enhanced safety by automatically retracting needles in the powered-off state
• Efficient switching of needle modules, supporting different operations or rapid maintenance
• Reduction of injury risk to users and patients/animals
• Mechanical and/or magnetic mechanisms allow reliable operation and reduce operational noise

Patent Abstract

The device has a movable actuating element (11) functionally coupled to a needle connection device (14) and formed at a drive module. A functional element (10) is assigned to the actuating element and formed at a needle module. The actuating element and the functional element are configured to shift the actuating element from a displacement position into another displacement position during coupling of the needle module at the drive module. The needle connection device is brought in to a coupling position in which a needle device is coupled to the needle connection device for operation. An independent claim is also included for a method for coupling a needle module to a drive module of a handheld device.
