Fully automatic injections that reduce anxiety

Remove the cap with a simple twist, apply OnePush to your chosen injection site—even over clothing—and press the large activation button to self-administer your medication. In a fraction of a second, the fully automatic, hidden needle inserts smoothly, delivers the dose, auto‑retracts, and locks the device for safe disposal. OnePush's smooth, controlled deployment is engineered to minimize needle sensation, offering calm, confident self‑injection at home.

Our science and engineering

Why hidden‑needle design matters.

Fear of needles and injections is common in chronic care and is associated with delayed initiation, poorer control, and lower adherence—making device design central to outcomes. OnePush hides the needle before, during, and after use and automates insertion and retraction with controlled motion, design attributes shown to increase patient acceptance and reduce anxiety for self‑injection.

Designed for at‑home persistency.

Patients managing weekly injectables prefer devices with fewer steps and minimal preparation. Multiple studies highlight strong preference for weekly dosing with simple, single‑use auto‑injectors. OnePush is engineered to support long‑term compliance and persistency for chronic disease therapies.

The economics of home injection.

Shifting appropriate injections from clinical settings to home can reduce visits and resource use, with systematic reviews showing lower overall costs when patients self‑inject compared to in‑clinic administration. Self‑injection also increases autonomy and reduces reliance on providers, contributing to cost and time savings.
