The state’s quasi-public technology investment agency has increased its support of a Farmington-based company that is designing information systems to enable to hospitals to better communicate with their patients.

Connecticut Innovations officials announced Monday that the agency has made a second $500,000 investment in Innovatient Solutions Inc. The agency had already invested $500,000 in the company last year.

Innovatient first product, nVision Information Therapy Solution, uses the existing in-room television system that most hospitals have to facilitate communication between patients and hospital staff. Using their in-room televisions, patients can communicate with hospital staff about pain levels, meal preferences and other matters.

The patient messages are delivered to hospital staff via personal computers or hand-held devices.
