Featured Case Studies

Case Study 1: Medical Bassinet

Next generation medical bassinet

New standard of care

A “couplet” refers to the mother and newborn as a single patient. Increased access and interaction with the infant has better patient outcomes and post-partum experience. Product allows the infant to safely stay with the mother.

• Fewer dropped infants
• Fewer infant smothering events
• Lowers burden on nursing staff and reduces hospital floor space needs

TRN was responsible for full engineering design, with external industrial design support
