  • Publication number: 20250032303
    Abstract: A device for connecting and transferring contents between a surgically created first orifice and a surgically created second orifice is provided. The device comprises a hollow body member and first and second tubular legs depending from the hollow body, and being adapted for insertion into the first and second surgically created orifices respectively. The device further comprises a cap for closing the hollow body and completing a sealed pathway between the tubular legs for passively conveying contents between the first and second surgically created orifices. Sealing features of the device are provided that in combination operate to keep the contents away from unwanted skin areas and/or provide an easy-to-use device.

  • Patent number: 12178340
    Abstract: A liquid control tool enables users to control the timing and amount of liquid to be consumed. The liquid control tool includes a handle and a head attached to the handle. The handle has a cavity (e.g., for storing liquid). The head has a concave surface defining a bowl. The liquid control tool also has two one-way valves to control the flow of liquid into and out of the cavity. The first one-way valve allows fluid to transfer, through a first opening in the bowl, from an external environment into the cavity. The second one-way valve allows fluid to transfer, through a second opening in the bowl, from the cavity into the bowl. A user can use the liquid control tool to hold and combine their food with a liquid when the user squeezes the handle and is ready to eat the food.

  • Publication number: 20240189193
    Abstract: An improved feeding catheter is provided for feeding/recycling chyme to a distal stoma. The improved catheter includes a hollow tube having an end for insertion into stoma, and a second end adapted to be connected to a fluid source. The first end includes a retention feature comprising a plurality of ribs extending outwardly and longitudinally away from the tube and terminating at a nose junction. Web walls extend between at least one pair of adjacent ribs and the ribs further define a side facing opening configured for fluid to exit into the gastrointestinal tract. Further the retention feature can be moved between a relaxed condition and a stretched condition for insertion through the distal opening, wherein the maximum width of the retention feature in the stretched condition is less than the maximum width of the retention feature in the relaxed condition.

  • Patent number: 8920615
    Abstract: A salt water chlorinator (30) for a swimming pool includes an electrolysis cell having two anodes (98) and a cathode (94). Two scrapers (102), each of which is of titanium and includes scraping portions in the form of ribs (106) in contact with the opposite surfaces of the cathode, are reciprocated relative to the cathode (94) to remove scale deposits from the cathode (94). The scrapers (102) are mounted in a frame (110) and their scraping ribs (106) are curved such that the ribs (106) are self-biased against the cathode surfaces. A mechanism for reciprocating the scrapers (102) includes two solenoid coils (116) which act on cores (114) in a stem (112) of the frame (110). A control circuit for the electrolysis cell is contained in a housing (86) which is attached to a housing (82) for the electrolysis cell. The control circuit includes a flow sensor for sensing salt-water flow through the electrolysis cell.

  • Patent number: 8631995
    Abstract: The present invention consists of developing a technology with different processes to realize an optimal solar approach using a solar concentrator where distance screws are used that, when moving, allow the positioning of the mirrors whereby the reflected solar beam is directed to a focal point; the advantage of these processes is that each movement of the screws involves adjusting the position of all the neighboring mirrors, which allow a perfect alignment and adjustment of the mirrors.

  • Publication number: 20070289457
    Abstract: Methods of forming images on an outer surface of a golf bag are provided. A method can include the step of obtaining a photographic-type image to be formed onto a substantially flat side outer surface portion of a golf bag having a main bag body including an open end, a closed end, a club chamber positioned between the open and closed ends, and the substantially flat side outer surface portion. The method can also include controlling image production by sending the photographic-type image to a printer and activating at least one printer motor to form the photographic-type image onto the flat side outer surface portion of the golf bag, and printing the photographic-type image onto the substantially flat side outer surface portion of the golf bag so that the photographic-type image is readily visible and substantially permanently affixed.
