K-Haler (Inhaler) by Tiffany Fretwell
2017 - 2018, Platinum A' Scientific Instruments, Medical Devices and Research Equipment Design Award Winner
Today 300 million people suffer from asthma, with 250000 annual deaths attributed to it worldwide. The idea of breath actuated inhalers isn’t new, but many of these require a higher force and speed of inhalation for optimal drug delivery, which can be a challenge for patients with breathing conditions. The Critikal Study suggests that up to 4 out of 10 patients don’t inhale sufficiently hard and fast with their dry powder inhalers and this is associated with poor asthma control.
k-haler was designed to address many of the issues that have persisted since the invention of the first pressurised metered dose inhaler in 1956. It is breath activated, eliminating the need for patients to coordinate their breathing, but takes lower force to trigger it than most other breath actuated inhalers. k-haler’s unique technology has the potential to be suitable for a range of inhaled products and forms a platform for future drug development by Mundipharma.
Design Challenges
Tiffany Fretwell did not encounter any design challenges while designing the award winning K-Haler Inhaler.
Production Technology
k-haler has a combination of snap fits, top loaded counter mechanism, and automated label application. The main label creates the counter window and its design helps k-haler feel clean and simple, whilst also helping orientation. Labels are tamper evident, and allow the upgrade of colourways, regulatory information and branding. k-haler has a breath triggered valve, which when patients breathe in, automatically releases a dose. This unique valve removes the need for coordination during inhalation.
