Abstract
A device for enclosing a positive end valve (PEEP valve) and converting the PEEP valve to an inline valve for use in a differential multi-ventilation system is described. The device includes a housing configured to enclose the PEEP valve. The housing also includes a ventilator-side arm, a pass-through arm and a patient-side arm. The pass-through arm permits extension of the multi-ventilation system to add one or more patients to the system.
Claims23
A device for enclosing a positive end valve (PEEP valve) and converting the PEEP valve to an inline valve for use in a differential multi-ventilation system, the device comprising:
- a housing configured to enclose the PEEP valve, the housing including a ventilator-side arm, a pass-through arm and a patient-side arm,
- wherein the device is configured such that, when the PEEP valve is installed:
- gas flow is permitted between the ventilator-side arm and the pass-through arm;
- the ventilator-side arm and the pass-through arm are isolated from the patient-side arm by the PEEP valve when the PEEP valve is closed;
- gas flow between the patient-side arm and the ventilator-side arm is permitted when the PEEP valve is open;
- and
- the pass-through arm is configured to permit extension of the multi-ventilation system to add one or more patient circuits to the system.
A set of devices for assembling and connecting inspiratory and expiratory inline valves to each other, the set for use in a differential multi-ventilation system, the set comprising:
- an inspiratory device comprising:
- a housing configured to enclose a positive end valve (PEEP valve), the housing including a ventilator-side arm, a pass-through arm and a patient-side arm, wherein the inspiratory device is configured such that, when the PEEP valve is installed:
- gas flow is permitted between the ventilator-side arm and the pass-through arm in either direction,
- the ventilator-side arm and the pass-through arm are isolated from the patient-side arm by the PEEP valve when the PEEP valve is closed,
- gas flow from the ventilator-side arm to the patient side arm is permitted when the PEEP valve is open, and
- the pass-through arm is configured to permit extension of the multi-ventilation system to add one or more patient circuits to the system, and
- further including:
- a first connector on the housing of the inspiratory device;
- and
- an expiratory device comprising:
- a housing configured to enclose a PEEP valve, the housing including a ventilator-side arm, a pass-through arm and a patient-side arm, wherein the expiratory device is configured such that, when the PEEP valve is installed;
- gas flow is permitted to flow between the ventilator-side arm and the pass-through arm in either direction,
- the ventilator-side arm and the pass-through arm are isolated from the patient-side arm by the PEEP valve when the PEEP valve is closed,
- gas flow from the patient side arm to the ventilator-side arm is permitted when the PEEP valve is open, and
- the pass-through arm is configured to permit extension of the multi-ventilation system to add one or more patient circuits to the system, and
- further including:
- a second connector on the housing of the expiratory device,
- wherein the first connector and the second connector are configured to connect to each other.
