Valve Device for Controlling a Flow of a Fluid Through a Fluid Channel, Arrangement as Well as Multi-Way Device

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

This patent describes a valve device designed to precisely control the flow of fluids through flexible tubing by using a specialized crushing element that can regulate, restrict, or completely stop the flow. The valve uses a movable guide section and a crushing mechanism to adjust flow dynamically, suitable for both high-frequency and single-use operations. It is especially intended for integration into medical and cosmetic dosing and injection devices, enabling accurate administration of substances, even under back pressure.

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

• Automated and manual medical injection devices for precise dosing of drugs, vaccines, or therapeutic substances
• Cosmetic procedures like tattooing, permanent make-up, dermal fillers, and mesotherapy requiring controlled fluid delivery
• Microdosing systems for high-value, sensitive, or viscous fluids
• Devices for simultaneous or sequential injection of multiple agents (e.g., combination therapies)
• Medical dispensers or microvalves for minimally invasive treatments, including microneedle drug delivery systems
• Fluid control in laboratory instrumentation or diagnostic tools where contamination-free, disposable valve systems are beneficial
• High-frequency dispensing systems for precise droplet formation, such as jetting or pulsing applications
• Systems for cosmetic or medical extraction procedures (e.g., tattoo removal involving both injection and aspiration)

BenefitsContent extracted from patent full text and abstract with AI.

• Enables highly precise and adjustable fluid dosing, including very small volumes, improving treatment accuracy
• Supports both high-frequency and manual operation modes, increasing versatility for various devices
• Reduces risk of contamination since the fluid path is confined to easily replaceable/disposable components
• Easy integration into single-use, low-cost injection and dispensing devices due to simple, compact design and potential for mass production via injection molding
• Allows for parallel or multi-channel dosing by combining several valves, facilitating multi-agent therapies or high-throughput applications
• Works reliably even when injecting against tissue pressure, making it suitable for intradermal or subcutaneous treatments
• Minimizes cleaning and maintenance requirements, especially important for sensitive reagents or medications
• Adaptable to both contact and non-contact dosing/injection, widening application range from traditional injections to dispenser-type systems

Patent Abstract

The valve device comprises a section of a fluid channel which is formed in an inner tube (2) that is made of a flexible material. A crushing element (10) is formed on a valve component (1) which is provided for the inner tube. A guide section (13) is formed on the valve component. An independent claim is also included for an arrangement with a pressurization device.
