Abstract
A method and system for foot-actuated device to switch between a vacuum supply and an oxygen supply in a medical environment. The system enables a user to press down on the device to compress a first tube and open a second tube. When the user releases the device, the first tube is opened and the second tube is compressed.
Claims21
A foot-actuated device for alternately switching fluid flow from a plurality of different fluid sources, comprising:
- at least one first port configured to connect to a first fluid source;
- at least one second port configured to connect to a second fluid source;
- at least one output port configured to connect to a medical device configured to provide fluid flow from at least one of the plurality of different sources to a patient;
- at least one first tube in fluid communication with the at least one first port;
- at least one second tube in fluid communication with the at least one second port;
- a tube connector in fluid communication with the at least one first tube, the at least one second tube, and the at least one output port;
- a first occluder configured to compress the at least one second tube;
- a pedal configured to be pressed and change a configuration of the foot-actuated device;
- and
- a second occluder configured to compress the at least one first tube;
- wherein, when the pedal is not pressed, the foot-actuated device is in a first configuration wherein the second occluder is not compressing the first tube and the first occluder is compressing the second tube, allowing a first fluid to flow from the first fluid source to the medical device and blocking a flow of a second fluid from the second fluid source to the medical device and, wherein, when the pedal is pressed, the foot-actuated device is in a second configuration wherein the second occluder is compressing the first tube and the first occluder is not compressing the second tube, allowing the flow of the second fluid from the second fluid source to the medical device and blocking the flow of the first fluid from the first fluid source to the medical device.

A method for operating a foot-actuated device for alternately switching fluid flow from a plurality of different fluid sources, wherein the foot actuated device comprises:
- at least one first port configured to connect to a first fluid source;
- at least one second port configured to connect to a second fluid source;
- at least one output port configured to connect to a medical device configured to provide fluid flow from at least one of the plurality of different sources to a patient;
- at least one first tube in fluid communication with the at least one first port;
- at least one second tube in fluid communication with the at least one second port;
- a tube connector in fluid communication with the at least one first tube, the at least one second tube, and the at least one output port;
- a first occluder configured to compress the at least one second tube;
- a pedal configured to be pressed and change a configuration of the foot-actuated device from a first configuration to a second configuration;
- and a second occluder configured to compress the at least one first tube, wherein, in the first configuration, the second occluder is not compressing the at least first tube and the first occluder is compressing the at least one second tube and, in the second configuration, the second occluder is compressing the at least one first tube and the first occluder is not compressing the at least one second tube, the method comprising:
- operating the medical device, when the clamp of the foot-actuated device is in the first configuration, to provide a first fluid from the first fluid source to the medical device;
- pressing the pedal to change the foot-actuated device from the first configuration to the second configuration, causing the second occluder to compress the at least one first tube and the first occluder to release from the at least one second tube, to provide a second fluid from the second fluid source to the medical device.
