Our Valved Tee adapters make it easy to deliver aerosolized medication to your ventilator patients. Used in conjunction with a nebulizer, the Valved Tee adapter offers a safe and convenient way to introduce medication into the circuit. Unlike other tee adapters that require time-consuming and potentially hazardous breaks in the system, the Valved Tee adapter becomes a permanent part of the ventilator circuit. Its spring-loaded valve opens and closes the circuit during nebulizer insertion and removal. Because the adapter maintains a closed system, the risk of condensate being accidently sprayed into the air is greatly reduced. Choose from three sizes for placement at different locations in the circuit. With spring-loaded valve and cap.
