Definitions

• the pump is electrically operated and, typically, a single bag of solution is used by a patient over a 24 hour period for the controlled administration of cancer che otherapeutic agent, analgesic, insulin, or other desired medication.
• a single bag of solution is used by a patient over a 24 hour period for the controlled administration of cancer che otherapeutic agent, analgesic, insulin, or other desired medication.
• such pumps have carried batteries to power the pumping action over the 24 hour period.
• an alternate power system for the pumping of solutions to and from flexible collapsible containers is provided, being set up so that the patient cannot make the mistake of failing to change the batteries.
• the patient is better protected against accidental oversights on his part, and the critical medication can be provided to an independently living patient with greater reliability of
• each flexible solution container of critical medication is administered by the pump ⁇ being powered by a fresh battery every time, thus avoiding unnecessary and potentially critical failures of power in the pump systems.
• the invention can also be used in other areas, for example, for the administration of large volumes of parenteral solution
• a flexible, collapsible solution container and battery means having terminals are 25 permanently attached together, with the terminals being accessible to connect with electrically operated pump means for pumping the contents of the solution container.
• the battery means may be carried within a compartment of the container, the compartment being separate
• the solution container and battery means may be permanently attached together in peripherally sealed, side-by-side relation.
• the battery means may preferably be relatively flat, defining a length and width which are at
• the terminals may be positioned on the face of the battery which is opposed to the solution container.
• Flat batteries of the type described are commercially available from the Polaroid Company and may be modified by conventional means to be used in accordance with this invention, particularly in one of the embodiments described above.
• Figure 1 is a perspective view of the flexible collapsible solution container and attached battery means of this invention in the process of being installed in electrically operated pump means, for daylong, parenteral application of a critical medication to a patient who will carry the operating pump and solution container with him throughout the day while tne critical medication is administered through an intravenous catheter on a controlled, continuous basis.
• Figure 2 is a perspective view showing tne bag and battery installed in the pump of Figure 1, so that the pump now is ready for attachment to the patient's intravenous catheter.
• Figure 3 is a plan view of another embodiment of the collapsible solution container and attached battery of this invention.
• solution bag 12 being typically made in generally conventional manner of a pair of heat-sealed thermoplastic sheets of plastic such as polyvinyl chloride, with the heat sealing taking place at periphery 14.
• Flat battery 16, of a type which is available from the Polaroid Corporation, is carried on top of bag 12 as shown in Figure 1, and sealed thereto at periphery 14. This sealing may be accomplished by an ultrasonic welding technique, a solvent sealing technique, or use of an adhesive around the periphery 14, or, if desired, between the adjoining faces of bag 12 and battery 16, to render them permanently attached together.
• bag 12 carries connection tube 18 which, in turn, may connect to transfer set 20 of conventional design which, in turn, may terminate with an IV needle or a luer lock adapter 22 as may be desired, to either make an IV connection with the
• Luer lock adaptor 22 is covered with removable protector 23.
• Pump 24 may be of a design as described in the cited patent
• Housing 26 is provided which carries pump head 28 which may be of the design of the previously cited Olson patent application, with the further modification that a notch 30 is Q provided in latch 32 which locks and unlocks pivotable jaws 33, within which a portion of tubing 20 is provided.
• Tubing 20 surrounds a pressure head (not shown) which moves in a circular path of motion, compressing tubing 20 against the closed jaws 33 in the circular path of motion, and thus forcing solution
• Battery 16 carries terminals 36, 38.
• the combined battery and collapsible container 10 may be placed into pump housing 26, inverting the structure from the position shown in Figure 1 so
• terminals 36, 38 enter respectively into contact with spring terminals 40, 42 mounted in housing 26 as shown.
• Terminals 40, 42 connect to an electric motor in housing 26 for operating pump head 28.
• Tubing 18 and the adjacent section of tube 20 may be placed in trough 43, and lid 44 may be closed to
• OMPI be connected to the patient for precisely controlled administration of solution by pump 24 over an extended period of time, without risk of the battery going dead during the middle of the administration process.
• a two-chamber plastic bag 50 made in an overall conventional manner, for example, from a pair of peripherally heat sealed sheets of plastic and a transverse heat seal 52, defines a pair of chambers 54, 56.
• Chamber 54 is the chamber for the desired solution for administration and communicates with port tubing 58 which, in turn, can communicate with a transfer set 20 if desired.
• Chamber 56 isolated from solution chamber 54, carries a battery 58 which may be of the flat type, or may be another conventional type of battery, having terminals 60 protruding from the end of bag 50 for communication with a cable or wire communicating with the pump system to provide power thereto.
• a battery 58 which may be of the flat type, or may be another conventional type of battery, having terminals 60 protruding from the end of bag 50 for communication with a cable or wire communicating with the pump system to provide power thereto.
• Bag 50 can fold along line 62, if desired for insertion into a storage chamber of a pump for ambulatory use.
