Abstract
A disposable flow path having a manifold system that provides pressure resistance for the disposable device. The disposable device is comprised of a first rigid plastic sheet and a second rigid plastic sheet. Each sheet has two major surfaces and a thickness between them. At least one sheet surface has flow channels formed in it. The flow channels extend away from a first major surface and beyond the normal plane of a second major surface of the sheet. The sheets are liquid tightly sealed to each other at their adjoining first major surfaces. When each sheet contains a flow channel, the flow channels are aligned and in register with each other. One or more fittings can be secured in the flow channel(s) at an edge of the two liquid tightly sealed sheets. Alternatively, tubing is placed in the channels before the sheets are secured to one another.
Description
- The present application is Divisional U.S. Application of copending U.S. application Ser. No. 13/170, 926 filed on Jun. 28,2011 and U.S. Provisional Patent Application No. 61/360,644, filed on Jul. 1, 2010, the entire content of which is incorporated by reference herein in its entirety.
- This invention relates to a rigid disposable flow path for disposable manufacturing such as in pharmaceutical, biopharmaceutical, nutriceutical, food or beverage processing and the like. Moreover the invention relates to a rigid top and bottom portion attached to each other with a flow path formed in the adjoining faces of the top and bottom portion.
- Traditionally, fluid products such as biopharmaceuticals, food and beverages have been processed in stainless steel path ways. The steel, piping and fluid path ways need to cleaned such as with a hot caustic solution and then rinsed with several volumes of hot water and steam sterilized in between each use.
- One problem with such a system is making sure the system is properly cleaned and sterilized in between each use. Another issue is that the system is incapable of being flexible in size or configuration, limiting the user to a set volume and methodology dictated by the configuration.
- This has led to the recent adoption of plastic flexible containers and systems based on them. Most simply are plastic assemblies such as bags connected to each other by plastic tubing. One problem with such systems is that the system cannot be used at any high pressures due to the limitations of the plastic itself. A second issue is that it needs to be stabilized or retained to the surface on which it is used.
- One approach has been to use a clam shell or two piece manifold having a flow channel configuration or a relatively flat compressible surface between which the tubing of an assembly and/or the entire assembly can be held so that it can be kept in place and provided with some pressure resistance. See WO 2009/017614.
- Another option is to use a flat or unconfigured bag and manifolds that contain the desired flow channels in the manifolds. The bag is placed between the manifolds and slightly constrained. The bag portions corresponding to those portions below the flow channels of the bag are then slightly inflated with a gas or liquid such that the bag portions fill the flow channels of the manifolds. The manifolds are then closed around the bag forming the desired flow path within the bag while in the manifolds. See PR 0959435 filed Jan. 23, 2009.
- These devices have their limitations in terms of their complexity of operation and manufacture and their potential for leakage at pressure. For example, the use of separate components such as bags and tubes or an unconfigured bag and placing them in a manifold still limits one to the pressures at which the device may be run as the bag and often the tubes pressure resistance is only marginally improved by the use of the shell or manifolds. This is even more accentuated in the system using only a bag and forming the fluid pathways by inflating portions of the bag into the channels formed in the manifold inner surfaces. In this instance, the seal between the layers of the bag limits the amount of pressure that can be used. Additionally, when using individual components such as tubes connected to bags through a plastic port welded to the bag, one has to deal with obtaining and maintaining a good liquid tight seal between all the components. Most often a leak will occur where the tube is secured to the hag. The manifold devices do not stop such leaks from occurring and running the system at higher pressure and exacerbate the leak in some instances.
- The present invention provides a different device for forming a disposable pathway that is capable of holding and operating at high pressures and eliminating the leaks that may occur in other assemblies.
- The present invention provides a disposable rigid flow path which by itself or in conjunction with a clam shell or manifold system provides additional pressure resistance for the disposable device.
- In a first embodiment, the device is comprised of a first sheet of rigid plastic material and a second sheet of plastic material. Each sheet has a first major surface and a second major surface and a thickness between the first and second major surfaces. At least one and preferably both have flow channels formed in them. The flow channels are formed in the sheet (s) in manner such that the area of the sheet where the flow channels are formed extend away from the first major surface of the sheet and beyond the normal plane of the second major surface of the sheet. The first and second sheets are liquid tightly sealed to each other at their adjoining first major surfaces. In the embodiment where each sheet contains a flow channel, the flow channels of the two sheets are aligned and in register with each other. One or more fittings are secured in the flow channel(s) at an edge of the two liquid tightly sealed sheets so as to function as an inlet, outlet or other port for the system.
- In a second embodiment, the device is comprised of a first sheet of rigid plastic material and a second sheet of plastic material. Each sheet has a first major surface and a second major surface and a thickness between the first and second major surfaces. Both sheets have flow channels formed in them. The flow channels are formed in the sheets in a manner such that the area of the sheet where the flow channels are formed extends away from the first major surface of the sheet and beyond the normal plane of the second major surface of the sheet. The first and second sheets are liquid tightly sealed to each other at their adjoining first major surfaces. The flow channels of the two sheets are aligned and in register with each other. A tubing is run in the flow channels between the two sheets and one or more fittings are secured to the tubing in the flow channels at an edge of the two liquid tightly sealed sheets so as to function as an inlet outlet or other port for the system.

In this instance both sheets have the one ormore flow channels 14 formed in eachsheet sheets flow channels 14 are formed extend away from the firstmajor surface 8A or B of eachsheet major surface 10A and B of eachsheet sheet sheets sheet -
FIG. 10A-F shows various cross-sectional profiles of the flow channel of the second embodiment. For example the cross-sectional profile of each sheet can be a semi circle or semi oval as shown inFIGS. 10A and B respectively.

FIG. 11 shows a third embodiment of the present invention. In this embodiment the plastic sheets are formed as inFIGS. 1-3 with one sheet containing the flow channel(s) 14. Aflexible tubing 24 such as a rubber or polyolefinic tube is inserted into the flow channel(s) 14 before the twosheets -
FIG. 12 shows a fourth embodiment of the present invention. In this embodiment the plastic sheets are formed as inFIGS. 8-9 with eachsheet flexible tubing 24 such as a rubber or polyolefinic tube is inserted into the flow channel(s) 14 before the twosheets -
FIG. 13 shows a fitting 18A in thetubing 24 contained within theflow channel 14. If desired ahose barb 30 can be used to secure the fitting to thetubing 24. Alternatively, one can adhere, friction fit or melt bond the fitting 18A to thetubing 24. While shown with the embodiment in which bothsheets channel 14, one can use a similar device in the embodiment with only achannel 14 formed in onesheet - The sheets can be made from a plastic selected from the group consisting of polyolefins, polycarbonates, epoxies, fiberglass reinforced thermosets, carbon reinforced thermosets, carbon composites, polysulphones and polyetherimides.
- The one or more flow channels can be formed in the rigid plastic sheet(s) in a variety of manners. For example it can be vacuum formed by preparing a pattern of the flow channel configuration on a mold, heating the plastic sheet until it is soil and then applying a vacuum to the plastic sheet so as to pull it against the pattern and form the channel configuration. Alternatively, if the plastic thick enough it may be formed by removing the plastic in the areas of the desired flow path such as by a router or a CNC milling machine, a laser or chemical etching. In another embodiment, the plastic is melt cast or solvent cast over a pattern containing the pattern of the flow channel configuration (either as a positive or a negative pattern) and it is allowed to cool or evaporate the solvent. For thermosets, a similar process may be used and the thermoset is allowed to cure or set against the pattern to form the device.
- The
holes 22 may be formed as part of the process of making the sheets such as when the sheets are cast or they may be formed afterward such as by drilling or laser etching the hole in the desired location. - Once formed, the two sheets are aligned and securely held together in a liquid tight manner. This may be accomplished by adhesives that hold the two sheets together, or by solvents that selectively dissolve a portion of the adjoining plastic of each sheet and welds the two together as the solvent is evaporated. Heat sealing and heat or sonic or ultrasonic welding can also be used. Lasers and heat, platens can be used for the heat welding. Alternatively, the two sheets can be secured by clamps around their edges. This may in some instances necessitate the use of a peripheral gasket. Likewise, a series of nuts and bolts or rivets, optionally with a peripheral gasket can be used to seal the sheets together.
- At the edge of the sheets where the flow channel exits or enter the sheets, one can mount a fitting to the opening to allow for the attachment of tubing, filters, and other such ancillary-equipment. In many instances the fitting can be an elastomer material that is simply compressed and held in the flow channel as shown in
FIG. 3 . Optionally, it may be retained simply by a friction fit between the inner diameter of the flow cannel and the outer diameter of the fitting. The use of adhesives, heat or sonic welding or solvent welding may also be used depending upon the material selected. As shown inFIG. 13 , the flow channel(s) 14 may be formed with a retention device such as an undercut 100. While shown as a rectangular undercut it could be any other shape that retains the fitting. - A device according to the present invention is made in the following manner. A lay out or design of the flow channel is charted and then a mold is formed such as by laying out metal or wood half round pieces. The pieces can be bent or cut to the particular configuration desired. The pieces are attached to a flat surface such as a vacuum board for a vacuform machine. If desired or required, the pieces can be treated with a release agent such as silicone or various machine, mineral or vegetable oils or waxes (natural or synthetic) to ensure the mold does not stick to the plastic sheet. Alternatively a PTFE coating can be applied to the pieces.
- A piece of rigid plastic of a size to fit the board is then either simply placed over the board and pieces and then heated such as by a heat lamp or heat gun or the plastic sheet is heated until it is pliable first and then applied to the board. The plastic is clamped in place and a vacuum is drawn to pull the pliable plastic against the mold. The plastic is cooled and released from the board.
- If only one sheet is to contain the channel(s), it then secured to a flat sheet of plastic such that the channel(s) is formed at the interface between the faces of the two sheets.
- If both sheets are to contain the channel(s) either a second sheet is simply made or if it is complicated a second mold which mirrors the first (ie is reciprocal to the first) is made and a second sheet is formed in a similar manner to the first.
- The same type of mold can be used with plastic that is formed from molten material which is poured over the mold or fiberglass or other composites by manufacturing the sheets over the mold(s) and using squeegees or rollers to ensure a good molded surface.
- Another method making the device is to simply rout out the channel(s) with a router device or CNC machine or laser or chemical etch as described above.
- If the device will contain tubing it is inserted between the sheets before they are secured together. If no separate tubing is used, the end fittings are secured between the sheets before or during when they are secured together. In the case of no separate tubing being in the channel(s), one may want to wash or flush the channel(s) before use to remove any release agent that may be left. Alternatively, this can be done as each sheet is made.
- Once the sheets have been made and secured to each other, the fittings are attached to a supply of liquid and a means to hold the processed material such as a bag, tank, and the like. The liquid is run through the channel(s) and treated such as by a filter that is in line in the device.
