Devices and adapters that enable the sterile and secure transfer of liquids, such as medications or diluents, between containers (vials, syringes, IV bags) while minimizing exposure to contaminants or air.
Couplings and fittings designed for specific fluid properties (e.g., cryogenic, chemical, medical, high-pressure) or requiring aseptic conditions, low-spill characteristics, or antimicrobial features to ensure safety and integrity.
Systems that integrate digital technology, sensors, or connectivity to monitor, track, or automate aspects of medication administration, often providing data feedback, personalized recommendations, or secure logging.
Devices or systems designed to precisely measure and deliver specific doses of medication, often incorporating automated mechanisms, dose-limiting features, or hands-free operation.
Mechanical or electromechanical systems designed for precise, often self-administered, delivery of medicaments, including features for dose setting, needle insertion/retraction, and safety mechanisms to prevent premature activation.
Mechanisms allowing rapid, secure, and often sealed attachment and detachment of pipes, tubes, or hoses, frequently featuring locking, sealing, and release components for efficient assembly and maintenance.
Tubes, hoses, or ducts incorporating additional components or features beyond simple fluid conveyance, such as embedded electronics (sensors, heaters), structural reinforcement, or segregated compartments for cable routing.
Minimally invasive medical devices, typically flexible tubes, inserted into body lumens to deliver substances, remove obstructions, or perform localized treatments like ablation, dialysis, or drainage.
Valves engineered to automatically open or close based on pressure differentials, preventing over-pressurization, controlling flow direction, or suppressing backflow in fluid systems.
Mechanisms and control systems for precisely moving valve elements, often involving electric motors, cams, solenoids, or pneumatic/hydraulic pilots, to achieve desired flow or position.
Design and application of devices that are inserted into the body or implanted to treat diseases, modulate physiological functions, or repair anatomical structures.
Devices that assist in the physical modification or mixing of medications prior to administration, such as crushing solid drugs, cutting pills, reconstituting lyophilized products, or extracting from other devices.
Incorporating sensors and processing capabilities directly into valve systems to monitor operational state, detect malfunctions, measure flow parameters, or verify proper installation.
Specialized valve designs for domestic and commercial applications involving water distribution, temperature control, and air conditioning, often focusing on integration, materials, and specific flow characteristics.
Methods and devices for generating, transferring, storing, and utilizing electronic or digitally encoded keys and access credentials, including physical keys with integrated digital information for enhanced security or convenience.
Valves specifically designed for managing fluid power in hydraulic or pneumatic systems, including components for pressure regulation, flow direction, and system centering.
Systems that manage and enforce entry or usage privileges using digital credentials, biometric identification, or remote control, often incorporating network connectivity and real-time status updates.
Systems and methods for non-invasive or minimally invasive collection and analysis of physiological data (e.g., blood pressure, electrolytes, genetic markers, B cell repertoire) to assess patient health status, screen for conditions, or aid in diagnosis.
Locks integrating electronic components for remote control, wireless communication, internet connectivity, and digital credential management, often including features for user identification and access monitoring.
Hollow-fiber and flat-sheet membranes for blood purification, hemodialysis, hemofiltration, and related extracorporeal therapies.
