Clinical innovation that puts people first.
BleedingBlocks has been developed with regulatory compliance and clinical readiness as guiding priorities.
Designed to complement—not replace—traditional phlebotomy, the device is single-use and sterile, aligning with infection control standards and designed to integrate seamlessly into existing laboratory workflows without modification. Clinical evaluation, conducted in collaboration with the University of Melbourne under ethical approval, demonstrated reduced blood loss, improved patient comfort, and confirmed that samples are suitable for accurate pathology analysis.
BleedingBlocks is progressing through the Therapeutic Goods Administration (TGA) pathway, supported by evidence from early clinical trials and compliance processes that ensure patient safety and data integrity. These steps form the foundation for broader clinical adoption in hospitals, oncology clinics, paediatric wards, and community care settings.
How it works
Gentle Venipuncture
A standard butterfly needle is inserted with routine technique — requiring minimal training and no change to existing practice.
Passive Collection
Blood flows naturally into the capillary tubes through passive venous pressure and gravity — no suction involved, reducing strain on fragile veins.
Small-Volume, No Trauma
Only 2 mL is collected per draw, dramatically reducing patient trauma and the risk of anaemia.
Seamless Lab Integration
Samples are sealed and transported directly into existing lab workflows — no modifications or extra equipment needed.
Who BleedingBlocks is for
Pathology services
A cost-neutral solution that integrates seamlessly with existing laboratory workflows, improving sample integrity without the need for new equipment or processes.
Paediatric Wards
Gentle, low-volume blood draws designed for children with fragile veins, reducing pain, trauma, and the need for repeated attempts.
Oncology Clinics
Supports patients vulnerable to iatrogenic anaemia by collecting significantly smaller blood volumes, making frequent testing safer and less invasive.
Home Nursing Teams
Provides an easy-to-use, minimally trained method for safe blood collection in the home, offering comfort and reliability outside of hospital settings.
