Dalcon Communication Systems, Nashville, which makes inpatient communication tools for nurses, has changed its name to Amplion Clinical Communications on the heels of a financing round.

The technology company said in an e-mailed news release that it has raised $3.75 million in a financing round led by Solidus and Council Capital, two Nashville venture-capital firms. The funds are part of TNInvestco, a program set up to support businesses in the state.

Amplion plans to use the funds to expand its sales efforts to hospitals across the country, the release said. The 33-year-old company said the name change reflects its focus on inpatient nurse communication systems.

The company's flagship product, the Amplion Alert, is a wireless communications system that allows nurses and other clinicians to monitor patients in real time. It tracks physician rounds, bed turns, pain scores and patient needs.

It is designed to reduce complications such as falls and prevent "alarm fatigue" among nurses, the release noted.
