Abstract: An example medical device includes a container and tube set arranged and configured to couple to an endoscope, a first gas supply, and a second gas supply for use in an endoscopic procedure. The container and tube set includes a container having an interior volume configured to contain a fluid, a gas supply tube having a first end and a second end in fluid communication with the interior volume of the container, and a coupling mechanism having a first end and a second end, wherein the first end of the coupling mechanism is configured to engage with the second end of the gas supply tube and the second end of the coupling mechanism is configured to engage with both the first gas supply and the second gas supply interchangeably.

Abstract: Devices, systems, and methods for mitigating leakage from connectors and tubing of an endoscope system when the connectors and or tubing are disconnected from fluid ports of the endoscope system. A tubing assembly for connecting a fluid line to an endoscope and a fluid source may include an elongate tube having a lumen, a connector coupled to an end of the elongate tube and having a port in fluid communication with the lumen, and a fluid control component configured to selective adjust fluid flow through the lumen and the port. The fluid control component may be located in one or more of a cover for the fluid source, the tubing, the connector, and/or other components in fluid communication with the lumen. The fluid control component may be a valve. The valve may be manually actuated from a closed position to an opened position.

Abstract: Methods and systems for refilling a container during an endoscopic procedure. An illustrative reservoir may be placed in selective fluid communication with a water bottle. The water bottle may form a fluid tight seal with the reservoir to transfer water from the water bottle to the reservoir.

Abstract: The present disclosure, in its various aspects, is directed to expandable guide devices, implementation methods, and related systems. In one example, an expandable guide device is configured to receive an instrument through an instrument lumen of the device. Each of a plurality of expandable members are disposed circumferentially about a body of the device that defines the instrument lumen, and each expandable member is configured to be independently transitionable between an expanded configuration and an unexpanded configuration.

Abstract: A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. One or more charms can be included with the links to add additional aesthetic options.

Abstract: A first request to evict a first cache line that is stored in a cache memory may be received. The first cache line may be evicted based on a replacement policy. A second request to evict a second cache line from the cache memory may be received. Following the receipt of the second request, it is determined whether a condition associated with the replacement policy has been satisfied. If the condition associated with replacement policy has been satisfied, then the second cache line may be evicted based on a random replacement policy.

Abstract: The subject matter disclosed herein provides methods for detecting a user's loss of focus while reading content from an electronic device, paper, or other medium and prompting the user to refocus his/her concentration. This method can maintain a user profile that includes alert parameters. The alert parameters can include a prompt timer period and a type of prompt to be generated. The prompt timer period can specify a maximum allowable gaze time before one or more prompts are generated. The method can determine whether data received from a device tracking a movement by one or both eyes of a user is representative of active reading of content viewed by the user. One or more prompts can be generated based on the determining. Related apparatus, systems, techniques, and articles are also described.
