A subcutaneous catheter set is disclosed in which a multilumen catheter tube has a tissue cuff connected about its outer circumference. A lock adapter has a plurality of conduits in communication with the lumens of the multilumen catheter tube. A complementary lock adapter is connected to either another multilumen catheter tube, a plurality of single lumen lines, a plurality of injection tubes or may be plugged to act as a seal. The two lock adapters can be locked together so that the subcutaneous multilumen catheter may be connected directly to any of the items attached on the complementary lock adapter.

Multilumen catheter set

A method of sequential intravenous infusion of a plurality of fluid solutions is disclosed in which a spacer solution is administered alternately with the fluid solutions to prevent the fluid solutions from substantially mixing with one another.

Method for sequential intravenous infusion of multiple fluids

An infusion pump is disclosed in which a canister of compressed gas is regulated to provide a continuous source of pressure to one or more compressible fluid sources. Valves on the outlets of the sources prevent fluid from escaping except when the valves are opened. The valves are opened by solenoids which are selectively activated to open the valves.

Infusion pump

A valve is disclosed which includes a hollow cylindrical housing having a plurality of input sites and a rotary core member having an output pasageway. The input sites which are not in communication with the output passageway are sealed. The valve may also include a primary input site connected to a conduit surrounding the rotary core member of the valve. The valve is demountable on a control apparatus for performing a method of administering a plurality of fluids intravenously to a patient. According to the method of the present invention, a neutral solution is provided in between each of the other different fluid solutions being infused into the patient. The control apparatus of the present invention may be programmed to automatically provide the patient with a prescribed amount of each fluid solution through the catheter tube.

Apparatus and method for administering multiple fluid infusions

A subcutaneously tunneled catheter set is disclosed in which a first multilumen catheter is connected to a second reinforced multilumen catheter. A tissue cuff is located near the connection between the two catheter tubes. The disclosure includes a multilumen connector made from a housing that provides conduits between two sets of ports which connect to catheter tubes at either end. The tissue cuff is connected around the outside of the multilumen connector. A multilumen locking connector is provided so that the subcutaneously tunneled multilumen catheter set may be connected directly to an exterior multilumen catheter tube.
