Abstract
An improved tubing device, preferably for use in the medical industry is provided. The tubing device provides a seamless transport path by using the tubing itself as the transport means without any other internally wetted parts, or connections, to provide a substantial reduction in the number of fluid contact components, and eliminate the need for cutting tubes into segments to be later bonded via tubing connectors. This can reduce the risk of contamination of the transported materials and can also reduce the use of chemicals such as adhesives and bonding agents.
Claims58
A tubing device for transporting fluids comprising:
- a support member, said support member comprising:
- a curvilinear channel formed therein for receiving a tube;
- and
- an adhesive disposed in said channel for securing a tubing into the channel.
A tubing device for use in the medical industry, said tubing device comprising:
- a tube support comprising a curvilinear channel disposed therein for receiving a piece of tubing;
- and
- means for holding a piece of tubing in said channel.
A tubing device for transporting a biological fluid, said tubing device comprising:
- a tube support comprising a curvilinear channel disposed therein for receiving a piece of tubing;
- and
- structure to hold a piece of flexible tubing in said channel.
A method for transporting a fluid for a medical application, said method comprising:
- providing a piece of flexible tubing, the tubing comprising a single piece and having no adhesives on the interior surfaces;
- providing a support device for the flexible tubing, the support device being configured to prevent flow constricting areas from forming in the flexible tubing;
- and
- transporting a fluid through the flexible tubing.
A kink-resistant tubing apparatus comprising a support structure, said support structure being configured to substantially prevent kinking in a weight bearing flexible tube disposed within said support structure.
A kink-resistant tubing apparatus comprising a support structure, said support structure being configured to substantially prevent kinking in a weight bearing flexible tube disposed within said support structure, and said support structure being configured so that said flexible tubing is adjustable within said support structure.
A kink-resistant tubing apparatus comprising a support structure, said support structure being configured to be weight bearing to substantially prevent kinking in a flexible tube disposed within said support structure when weight is applied to said flexible tube.
A kink-resistant tubing apparatus comprising a support structure, said support structure being configured to substantially prevent kinking in a flexible tube disposed within said support structure when weight is applied to said flexible tube, and said support structure being configured so that said flexible tubing is adjustable within said support structure.
A kink-resistant tubing apparatus which is weight bearing.
An adjustable kink-resistant tubing apparatus which is weight bearing.
A biological fluid filtration system comprising:
- a blood container;
- a leukocyte depletion device, said leukocyte depletion device having an inlet and an outlet with a filter media disposed therebetween, said leukocyte depletion device being disposed downstream from said blood container;
- a first conduit, said blood container and said inlet of said leukocyte depletion device being in fluid communication through said first conduit;
- a blood-receiving container, said blood receiving container being disposed downstream of said leukocyte depletion device;
- a second conduit, said outlet of said leukocyte depletion device being in fluid communication with said blood receiving bag through said second conduit;
- a bypass line, said bypass line providing fluid communication between said blood container and said blood receiving container;
- said bypass line comprising a loop, said loop of said bypass line being configured to be disposed above said blood container at a sufficient height to prevent the passage of fluid around the leukocyte depletion device;
- and
- a tube support device, said loop of said bypass line being disposed in said tube support device, and said tube support device being configured to support substantially the entire weight of said biological fluid filtration system without substantially crimping said bypass line.
A kink resistant tubing apparatus comprising a support member, said support member comprising:
- at least two channels through said support member for retaining tubing;
- and
- structure to support the weight of said tubing apparatus without substantially deforming tubing retained by said support member.
