Needle Free Injection Gets Real with FlowBeams

Rethinking Injection: FlowBeams and Needle-Free Delivery

The use of needles in medicine is widespread, but it’s not without complications — from medical waste to needle-stick injuries and widespread patient anxiety. FlowBeams offers a different approach: a needle free injection system based on high-velocity fluid mechanics that delivers drugs through the skin without piercing it.

This method isn't intended to replace all traditional syringes, but it does present a promising alternative in cases where reducing pain, waste, or complexity is a priority.

What Is FlowBeams?

FlowBeams is a needle-free drug delivery device designed to administer medication using a narrow, pressurized liquid jet. The liquid is accelerated to high velocity and directed through a micro-orifice, producing a stream that penetrates the outer layer of skin — the stratum corneum — without the need for a metal needle.

This process relies on the physical force of the fluid itself to deliver the drug to the desired depth, whether intradermal, subcutaneous, or shallow intramuscular.

How It Works: Technical Overview

FlowBeams likely operates using the following jet injection principles:

• Pressure Generation: A mechanical or electromagnetic actuator rapidly builds pressure within a sealed drug chamber.

• Jet Formation: The pressurized fluid is expelled through a very fine nozzle (typically around 100 microns), forming a narrow jet of liquid.

• Skin Penetration: The jet travels fast enough (100–200 m/s) to pass through the outer skin layer without cutting or puncturing tissue.

• Controlled Delivery: Flow rate, jet speed, and duration are calibrated to deliver a precise dose at a target depth.

This approach allows for injections without needles, potentially minimizing pain and reducing the risk of contamination from sharp waste.

Where It Applies

Needle-free injectors like FlowBeams are not intended to replace all injection methods. However, they can be beneficial in settings where:

• Patient discomfort or needle phobia is a barrier to care

• Sharps disposal is difficult or hazardous

• Mass vaccination or frequent injections are required

• Minimal training or faster administration is needed

FlowBeams may be suitable for delivering medications such as vaccines, insulin, low-viscosity biologics, and hormone therapies, provided the formulations are compatible and delivery depth is sufficient.

Benefits and Limitations

Potential Benefits:

• No needle-stick injuries or sharps waste
• Reduced pain and anxiety for many patients
• Faster workflow in some clinical environments
• Portability for use in field settings or mass campaigns

Important Limitations:

• Not all drugs are compatible with jet injection
• Intramuscular delivery may not be achievable with all devices
• Calibration is critical to ensure accurate depth and dosage
• Regulatory approval must be obtained for specific medical applications and regions

FlowBeams, like all needle-free systems, must be carefully evaluated for safety, efficacy, and drug compatibility before clinical use.

The Broader Context: Evolving Drug Delivery

FlowBeams is part of a broader movement toward less invasive, more efficient drug delivery. From microneedle patches to oral biologics, innovators are working to simplify the way medications are administered — particularly in global health, chronic care, and vaccine distribution.

While needle-based injections will remain essential for many therapies, needle free injection systems can reduce barriers to access and improve patient compliance when deployed appropriately.
