A means and method to facilitate connecting, more specifically a means and method to facilitate the connecting of tubes or hoses that may be interspersed by and attached to connectors. They may be from an aseptic material container with a material connector attached to a terminus connector, that may have tubes or hoses attached, that may then lead to a terminus. The connectors may be within or critical elements may be within an enclosure that creates an environment in which to make the process and completion of connecting the connectors sterile or aseptic.
A continuing need exists to prevent contamination of a material, such as a fluid, where a material is needed to be transitioned from a container to a terminus in an uncontaminated condition. The means and method of making connections of hoses or tubes could be comprised of interspersed connectors that lead from a material container through hoses or tubes, that may have additional connectors and through to other hoses or tubes and other connectors that then lead to a terminus. Its use would be applicable in a multitude of industries among them medical, bio-medical, food and beverage.
It is the object of the invention to improve upon systems that allow for making an aseptic connection so that all parts of a system that may need to be, are sterilized to be made sterile. It draws upon asepsis concepts used in isolating procedures such as in glove boxes, clean rooms, aseptic fillers and others to sterilize and prevent exposing relevant parts of the system to contaminants.
It is another objective of the apparatus to provide for the means and method to make a sterile or aseptic connection that may be simple to make, may be simple to use, may use what may be less complex connectors, may use what may be modified connectors, may use what may be added parts to existing connectors and may be able to easily replace parts as needed.
A means and method embodying the invention are hereinafter described, by way of example, referenced to the accompanying drawings.
While this invention includes embodiments in different forms, the embodiments shown in the drawings and described herein are to be considered exemplifications of the principles of the invention and are not intended to limit the broad aspect of the invention to the embodiments illustrated and described herein.
A means and method
To operate, enclosure 1 may be part of or may be pre-attached to the terminus side connector 4. While terminus side connector 4 and enclosure 1 is elevated with the foramen that will fit over the material side connector 3 being the elevated portion, sterilant 10 is dispersed gradually into enclosure 1 by means of alternative sterilant connector 9 through attached hose or tube 2 leading from sterilant source 13 propelled by sterilant propulsion mechanism 11. This begins the internal sterilization of terminus side connector 4 and the parts within enclosure 1 before continuing the connection process. When sterilant 10 reaches the unattached foramen of enclosure 1, sterilant propulsion mechanism 11 is halted and enclosure 1 is attached to material side connector 3 using enclosure attachment 5 and that may use securing means 12. This begins to allow for the sterilization of material side connector 3 and other exposed areas within enclosure 1. After a pre-determined time, sterilant propulsion mechanism 11 is started, then a material propulsion mechanism is started. Sterilant 10 is drawn from enclosure 1 into an internal material conduit of the terminus side connector 4, then through the hose or tube 2 that leads to terminus 8 and may continue through to the point it leaves the terminus by using a propulsion mechanism and dispersing mechanism for terminus 8. After a predetermined amount of time the various propulsion mechanisms are turned off. Sterilant 10 has sterilized the internal portions of Terminus side connector 4, internal portions of hose or tube 2, then sterilized internal portions of a conduit through terminus 8 and possibly through it to the point a material exits terminus 8. Once a predetermined amount of time has been completed for the completion of the sterilization process, connectors 3 and 4 are then brought towards each other decreasing the length of enclosure 1 until a connection is completed within enclosure 1. It is maintained in place as a completely enclosed system that has been sterilized and thus prevents further exposure to contaminates. Sterilant propulsion mechanism 11 may be but not limited to a peristaltic pump, reciprocating pump or other types that would prevent contact between the fluid and pump. It may have variable speeds.
Sterilant connectors may contain check valves 7 to prevent backflow from enclosure 1 into hose or tube 2 leading to sterilant source 13. Connectors 3 and 4 may also contain check valves 7 to prevent backflow into other portions of the system such as but not limited to the material container 6.
Securing means 12 may be a plurality of types and may include but not limited to screw on, clamp, wire clamp, banjo, slip joint nut with slip joint washer and compression clamp.
A means and method
In this embodiment enclosure 1 is part of terminus side connector 4 and may have two hoses or tubes connected by an additional means of attachment, one for sterilant dispersal and the other for material transmission. A conduit of transmittal for sterilant might run parallel to a material transmission conduit within terminus side connector 4. Enclosure 1 that surrounds and may be a part of terminus side connector 4 or may be attached to it by means of enclosure attachment 5.
To operate enclosure 1 with terminus side connector 4 are attached to material side connector 3 using enclosure attachment 5 and may use securing means 12. A sterilant propulsion mechanism 11 is initiated to propel sterilant 10 from sterilant source 13 through hose or tube 2 that is connected to terminus side connector 4 and then through a means of transmittal which is then dispersed into enclosure 1. When sterilant 10 completely fills enclosure 1 sterilant propulsion mechanism 11 is stopped. After a predetermined amount of time sterilant 10 has sterilized all within enclosure 1. Sterilant propulsion mechanism 11 is started, then a material propulsion mechanism and what may be a dispersing mechanism of terminus 8 are started. Sterilant 10 is drawn from enclosure 1 into a material conduit in terminus side connector 4, then through the hose or tube 2 that leads to terminus 8 possibly through it to the point a material exits the terminus 8. After a predetermined amount of time sterilant propulsion mechanism 11, a material propulsion mechanism, and a dispersing mechanism are turned off. Sterilant 10 has then sterilized the internal portions, including what might be a material conduit of terminus side connector 4, tubes or hoses 2, to terminus 8 and as well as possibly through what may be a conduit to the point a material exits the terminus 8. At this point, connectors 3 and 4 are brought together by possibly using the portion of terminus side connector 4 that remains outside of enclosure 1 to bring them together until the connection within enclosure 1 is completed. A means of securing the internal connection may be used. It is maintained in place as a completely enclosed system that has been sterilized to prevent exposure to contaminates. Enclosure 1 and terminus side connector 4 may be of types that can be replaced as needed.
Seals such as but not limited to gaskets or O rings may be employed on connector 3 and 4 to create a seal for prevention of sterilant or material escaping and introduction of organisms into enclosure 1 and other parts of the system, as well as for creating a tighter fit for connector 3 and 4 at points of contact to perform a function that might assist in securing the connection.
An alternative sterilant connector 9 on enclosure 1 may be utilized, as well as other means such as but not limited to a bayonet connector to facilitate the dispersing of the sterilant 10 into enclosure 1.
Sterilant propulsion mechanism 11 may be a but not limited to a peristaltic pump, reciprocating pump, gravity, pistons, bellows, pressure pumps, or other types that would prevent contact between the fluid and pump. It may have variable speeds.
Sterilant connectors may contain check valves 7 to prevent backflow from enclosure 1 into hose or tube 2 leading to sterilant source 13. Connectors 3 and 4 may also contain check valves 7 to prevent backflow into other portions of the system such as but not limited to the material container 6.
Securing means 12 may be but not limited to a plurality of types and may be but not limited to include screw on, clamp, wire clamp, banjo, slip joint nut with slip joint washer, lever lock and compression clamp.
