Abstract
A device for placing a lung in a variety of different inflation states using positive air pressure. An exemplary device includes a housing and an air supply component. The housing includes a platform receives at least one of a synthetic lung or a real lung. The platform is at the same air pressure as a surrounding environment. The air supply component is located within the one or more internal cavities of the housing. The air supply component inflates the synthetic lung or the real lung with positive pressure.
Claims18
A system to simulate breathing in an ex vivo lung, the system comprising:
- a pneumatic pump including an input pneumatically coupled to external air;
- a valve comprising:
- a first port pneumatically coupled to an output of the pneumatic pump;
- a second port configured to be in pneumatic communication with the ex vivo lung;
- and
- a third port for venting;
- a controller configured to allow air from the pneumatic pump to cause the ex vivo lung to simulate breathing by causing the valve to alternate between connecting the first port to the second port and the second port to the third port;
- and
- a sealable access port configured to be located between the second port and the ex vivo lung, wherein the sealable access port is configured to allow a medical device to pass therethrough, the sealable access port comprising:
- a first opening configured to be coupled to the ex vivo lung;
- a second opening coupled to the second port of the valve;
- and a third opening,
- wherein when the ex vivo lung is connected to the first opening, the sealable access port is configured to allow a medical device to pass into the ex vivo lung via the first and third openings;
- wherein the system simulates inhalation when the first port is connected to the second port and exhalation when the second port is connected to the third port.
11 more elements
A device comprising:
- a housing configured to receive an ex vivo lung, the housing being at the same pressure as a surrounding environment;
- an air supply component configured to inflate the ex vivo lung with positive pressure, thereby causing the ex vivo lung to simulate breathing;
- a minimum lung size control device configured to allow a user to set a minimum air pressure threshold value for the air supply component;
- a maximum lung size control device configured to allow a user to set a maximum air pressure threshold value for the air supply component selected to inflate the ex vivo lung;
- and
- a breath rate control device configured to allow a user to control speed for the air supply component,
- wherein the air supply component comprises:
- a pneumatic pump;
- a valve comprising:
- a first port pneumatically coupled to an output of the pneumatic pump;
- a second port configured to be in pneumatic communication with the ex vivo lung;
- and
- a third port for venting;
- and
- a controller configured to cause the valve to alternate between connecting the first port to the second port and the second port to the third port, and
- wherein the air supply component further comprises a fitting comprising:
- a first opening configured to be coupled to the ex vivo lung;
- a second opening coupled to the second port of the valve;
- and
- a third opening,
- wherein when the ex vivo lung is connected to the first opening, the fitting is configured to allow a medical device to pass into the ex vivo lung via the first and third openings.
