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

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

This patent describes a valve device for controlling the flow of fluids through a flexible hose. The core mechanism uses a cantilever arm with a squeezing element that presses against the hose to modulate or completely stop the fluid flow. This pressure is adjustable, and the device can be actuated by various means (electric, magnetic, mechanical, pneumatic, etc.). The system is scalable with multi-way valves and is suitable for high-frequency and precise dosing, making it particularly useful in medical and cosmetic procedures.

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

• Precise injection of medical drugs or vaccines at controlled depths and dosages.
• Cosmetic procedures such as tattooing, permanent makeup, or injection of fillers and therapies (e.g., carboxytherapy).
• Micro-dosing and accurate dispensing of multiple substances, possibly with on-demand mixing.
• High-frequency droplet dispensing systems in laboratory automation and diagnostics.
• Fluid handling in pharmaceutical or cosmetic manufacturing equipment.
• Miniaturized liquid handling in analytical devices or point-of-care diagnostic devices.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables highly accurate and repeatable fluid dosing, even at high frequencies.
• Simple mechanical design allows for miniaturization and low-cost, potentially disposable components.
• Reduces risk of contamination, as the fluid only contacts easily replaceable parts (hose and valve).
• Can handle a wide variety of fluids, including viscous medications, particulates, or mixtures.
• Adaptable to multiple actuation methods, offering flexibility for different applications and equipment.
• Supports both single and multi-channel operation for versatile use, including simultaneous dosing of multiple fluids.

Patent Abstract

Valve device for controlling a flow of a fluid through a fluid channel, with a hose (2), which is made of flexible material and in which a section of a fluid channel is formed, with a valve component (1) assigned to the hose (2), with a cantilever arm (8) which, on the valve component (1), is reversibly movable counter to a restoring force provided at least partially by the cantilever arm (8) itself, with a squeezing element (10), which is arranged on a distal end of the cantilever arm (8) for supporting the cantilever arm (8) on the valve component (1) and which is designed to press against an outer surface of the hose (2) and thereby control a flow of a fluid through the fluid channel, optionally until the fluid channel is closed, and with an actuator (11), which is assigned to the squeezing element (10) and which is designed to move the squeezing element (10) counter to the restoring force on the cantilever arm (8) into different control positions, as a result of which the pressure of the squeezing element (10) on the outer surface of the hose (2), and therefore the flow through the fluid channel, is controllable. The invention further relates to an arrangement with at least one valve device and a pressurizing mechanism, and also to a multi-way valve device.
