Abstract: A sterile fluid mixing reservoir for storing premeasured quantities of fluids for subsequent combination is disclosed. The reservoir has a flexible outer bag which fully encloses one or more inner containers. The inner containers have self-opening mechanisms thereon which are manipulable through the outer bag. The bottles can be manufactured from a flexible material which facilitates intermixing of the fluids contained within the bag and inner containers.

Abstract: A multiple-dose reservoir syringe and manifold fluid delivery system are disclosed. The multiple-dose syringe has an inner cylindrical chamber which is selectively communicable with an outer annular fluid reservoir. The fluid can be withdrawn from the outer reservoir to the inner chamber for subsequent ejection therefrom. Means are provided for maintaining the sterility of the fluid stored in the outer reservoir.

Abstract: A method and an appartus for safely infiltrating an area of subcutaneous tissue from a single entry point with an elongated needle which avoids puncturing blood vessels. The needle is substantially blunt so as to be capable of penetrating subcutaneous tissue and to divert blood vessels around the needle on insertion. Toxic local anesthetics can be injected during insertion of the needle without having to first retract the needle to verify that a blood vessel has not been punctured.

Abstract: The infiltration pump has an outer cylinder and an inner piston mounted for reciprocal motion within the cylinder. A fluid displacing seal is attached to one end of the piston. A coil biasing spring is placed within the cylinder between the piston and the fluid dispensing end of the cylinder. One end of the spring is seated against the fluid dispensing end of the cylinder. The other end of the spring is seated against an adaptor section which transfers the biasing force of the spring evenly over the face of the fluid displacing seal.

Abstract: A method and system of administering a dissociative unconscious type of anesthesia are disclosed. The method and system are designed for use in office surgical units and outpatient facilities. Administration by a nurse or a physician without anesthesia training can be done with minimum danger to the patient and minimum recovery time. The method and system utilizes the intravenous titration method of administration of a combination of drugs by which the patient is placed in a dissociative, unconscious state and maintained in this state until completion of the procedure, at which time the effect of the drugs is reversed by other drugs as desired. The intravenous anesthesia is supported by infiltration of a local anesthetic, such as Xylocaine. The combination of drugs include the basal hypnotic diazepam (Valium), a dissociated unconsciousness and general analgesia phencyclidine (Ketamine) and the narcotic analgesic Nisentil.
