StableMate: Autoinjector Stabilizer


Relapsing-remitting Multiple Sclerosis (RRMS) is a widespread autoimmune disease causing neurological disability that is characterized by periods of remission and relapse. RMSS is the most common form of MS, affecting roughly 2.5 million individuals world-wide with 200 new cases diagnosed per week. During periods of relapse, patients can experience mild to severe symptoms including muscle weakness, balance problems and overall decreased physical ability. In order to reduce the occurrence of relapses, subcutaneous medications must be administered regularly using an autoinjector. With limited strength, fading tactility and overall shot anxiety, self-injection is not common. Caregivers are relied upon to help with medical administration which results in decreased autonomy for patients and possible relationship strain. Training aids are available to help patients gain confidence with self-injections, however, because disease progression is inevitable, decreased physical abilities will still hinder self-injection capabilities.

Researchers at Arizona State University have developed an easy to use device that works with autoinjectors to enable seamless medication delivery regardless of capability or dependency.  The StableMate device improves injection performance and ultimately provides patients with greater confidence in performing self-injections to decrease anxiety and give them more autonomy. Injections in the triceps region were targeted, which is one of three major sites for autoinjection. A prototype device was developed and tested with users reporting that it provided the stability required to improve a user’s confidence and decrease the anxiety and pain normally associated with self-injections.

This novel device provides the stabilization necessary to allow patients to administer their own medication and give patients their autonomy and confidence back.

Potential Applications
