Winnoz’s vacuum-assisted Haiim makes finger prick blood draws more efficient

Winnoz's Haiim is designed to make collecting blood from fingertips easier, increasing the volume drawn so it can be used for more types of tests. The New Taipei City, Taiwan-based company's vacuum-assisted device can collect up to 150 to 500 microliters of blood from a finger prick, depending on the person, in about two minutes.

Winnoz is currently presenting Haiim and eGGi, its molecular detection device that supports isothermal DNA/RNA amplification methods, at CES' Taiwan Tech Arena pavilion, with the goal of finding new partners and investors.

Haiim was inspired by founder and chief executive officer Joses Hsiung's childhood memories of watching his mother go into clinics for regular blood testing. Since his mother's veins were hard to see, it often took multiple punctures for phlebotomists to draw enough blood. Eventually, her veins collapsed. Hsiung began working on the device to maximize the amount of blood that can be taken from finger pricks.

While finger blood draws are typically used for tests that require less than 10 microliters of blood, like glucose monitoring or cholesterol panel, Haiim can draw enough for ones that need a larger volume, potentially helping patients avoid venipuncture blood draws.

The device consists of two parts, the main unit and single-use cartridges that stores the blood until it is tested. Since many clinics and hospitals are understaffed, it is designed so personnel can start using it with less training than traditional blood collection methods. Haiim was approved by the Taiwan Food and Drug Administration in 2019 and is intended for use by health care organizations, clinics and hospitals.
