QurumFit

About

A helmet that is built with over 130 years of manufacturing expertise and by Japan's top physicians.


ヘルメット
To provide proper helmet therapy that stays with each child throughout their future, we work with medical institutions and physicians who meet the standards set by the Japan Helmet Therapy Evaluation and Certification Organization. We ask every partner medical institution and physician to commit to two things: "Examine the shape and development of the head at monthly checkups" and "Provide custom-made helmet therapy tailored to the child's growth at each monthly checkup." We believe the ideal helmet therapy cannot be achieved without close collaboration between physicians and the manufacturer. And our commitment doesn't end once the helmet is made.

We promise care that looks ahead to the child's entire life.

An unrelenting pursuit of medical craftsmanship
— "Qurum Fit," the latest medical device that realizes ideal helmet therapy

As a pioneer in cranial remolding helmet manufacturing,
we continue to pursue the ideal helmet, drawing on our expertise gained from over 20,000 treatment cases (*2).

    • Developed together with physicians at the forefront of infant cranial checkups and cranial remolding
    • Retains Qurum's breathability while introducing a newly developed, domestically made inner cushion for an even better fit
    • Washable cushions for easy and comfortable care

"Greater comfort. Lighter weight. A more natural fit."
We've created the ideal helmet that truly fits your baby.

  • A reassuring design that doesn't hinder growth

    A newborn baby's head circumference grows at a rapid pace. QurumFit gently cradles your baby's head with our uniquely developed low-resilience inner cushion, allowing treatment to proceed without hindering head growth. We prioritize your baby's safety and comfort just as much as treatment effectiveness.

  • 100% made in Japan, fully custom-made

    Made with state-of-the-art 3D printing technology, the helmet combines strength and lightness. Each one is fully custom-made for your baby, designed with hot and humid climates in mind.

  • Industry-leading lightness

    QurumFit weighs just 100–160g (*3) — lighter than your smartphone. A baby's head weighs approximately 1,000–1,500g. Through research into a weight that places no strain on the head or neck, and can be worn with peace of mind, we achieved a helmet weighing roughly 1/10 of the baby's head weight.
    *3 As this is a custom-made product, the weight varies depending on the size of the baby's head.

  • A fresh inner cushion at every checkup, matched to your baby's growth

    At each monthly checkup, the inner cushion is adjusted in millimeter increments to match your child's growth. This high level of precision maximizes treatment effectiveness. Because the cushion is renewed every month, the inside of the helmet also stays clean.

  • Breathable and easy to care for — comfortable helmet therapy for both baby and family.

    With its distinctive diamond-shaped ventilation holes and our uniquely developed, highly breathable inner cushion, the helmet offers comfortable therapy in any season. The inner cushion, as well as the helmet itself, can be washed with water, keeping it clean at all times.

Voices of the physicians involved in development

Babies cannot tell us when something hurts or feels uncomfortable. To catch that unspoken voice, collaboration between physicians and the manufacturer is essential. QurumFit was co-developed with physicians specializing in neurosurgery, pediatrics, neonatology, pediatric surgery, and plastic surgery.

The result is a helmet designed with babies and their parents in mind, down to the smallest detail.

We developed this new helmet in collaboration with leading physicians from various medical fields across Japan. For a baby's cranial remolding treatment, having the right support system is just as important as having the optimal helmet. We recommend helmet therapy that is properly supported by both physicians and the manufacturer, based on accurate diagnosis by doctors experienced in this field.

To maximize the degree of improvement from helmet therapy, we held repeated discussions with physicians across multiple specialties.

To maximize the improvement achieved through helmet therapy, it's important that families can put the helmet on easily, accurately, and without it shifting out of place. We have made repeated improvements together with physicians from each specialty and the manufacturer to achieve this. More and more families are concerned about their baby's head shape each year. If you have any concerns, please don't put it off. Consult a medical institution with a proper care system in place.
