The Bi-Flow D/R is designed to provide manual mechanical ventilation triggered by the operator to a nonbreathing patient. This is accomplished by providing the patient a source of oxygen from the Bi-Flow D/R through a device such as a facemask or endotracheal tube. Between the oxygen source and the patient interface is the Bi-Flow valve, which allows for the release of oxygen from its source when triggered by the operator thus providing emergency respiratory support. For the spontaneous breathing patient, the Bi-Flow D/R may be used as an Inhalator. This is accomplished by the patient triggering the valve with his/her negative inspiratory force and the saurce gas being delivered to the patient through a face mask.
Additionally, there is a non-rebreathing valve (reusable version or single patient use version) attached to the Bi-Flow D/R which directs the patient's exhalation back to atmosphere. The combination of the Bi-Flow D/R and the non—ebreathing valve as a single device is commonly referred to as a Demand Valve.
The power for the device is provided by the compressed oxygen source. There is no additional source of power for this device.
The Bi-Flow D/R will be sold by Spiracle Technology only by or on the order of a physician and is intended to be used exclusively by trained health care professionals. The Bi-Flow D/R will be sold as a component of a respiratory support system to be configured by the health care provider. As such, it will be compatible with all commonly available oxygen source and face mask connections.
