Abstract
A bypass system for respiratory therapy and anaesthesia having a first bypass conduit for receiving a gas flow and for receiving a filtration device. The bypass system also has an activation device for redirecting the gas flow within the first bypass conduit. A second bypass conduit is also present in the bypass system which has a passive control valve to redirect air flow within the second bypass conduit. A conduit interconnects the first and second bypass conduit for providing a passage of gases between the first and second bypass conduits.
Claims9
A bypass system for respiratory therapy and anaesthesia comprising:
- a) a first bypass conduit for receiving a gas flow and for receiving a filtration device;
- b) an activation device for redirecting the gas flow within the first bypass conduit, the activation device moveable between an open position and a closed position;
- c) a second bypass conduit for receiving the gas flow from the first bypass conduit and the filtration device;
- d) a passive control valve moveable between a first position and a second position in response to a corresponding position of the activation device, the passive control valve located within the second bypass conduit to redirect air flow within the second bypass conduit;
- e) a conduit interconnected to the first and second bypass conduit for providing a passage of gases between the first and second bypass conduit when activated by the activation device;
- and,
- wherein the activation device is activated when the first bypass conduit is not connected to the filtration device;
- and,
- wherein a pressure differential is created when the activation device is moved between the open position and the closed position, and the pressure differential a correspondingly moves the passive control valve from the first position to the second position.
A method for bypassing air flow for use in respiratory therapy and anaesthesia comprising the steps of:
- a) providing an air flow passage to a patient for assistance in artificial ventilation having an air flow passage;
- b) disconnecting a first bypass conduit from the air flow passage which activates a passive control valve within a second bypass conduit, the passive control valve moveable between a first position and a second position;
- and
- c) diverting the air flow into a conduit interconnecting the first bypass conduit and the second bypass conduit,
- wherein the disconnection of the first bypass conduit from the air flow passage increases a gas flow pressure in the first bypass conduit, thereby moving the passive control valve from the first position to the second position.
