Abstract
A dual injection site for use in transmitting parenteral fluid is provided in the illustrative embodiment, by joining a pair of symmetrically shaped members each having a passage serving as either an inlet or an outlet for parenteral fluid flow. A pair of pierceable, self-sealing diaphragms are sandwiched between the members and each diaphragm is aligned with a respective passage.
Claims23
An injection site for location between a parenteral source of fluid and a patient, which comprises:
- a first inlet for coupling to a conduit from a first liquid container;
- a second inlet having a pierceable, self-sealing diaphragm positioned therein;
- a third inlet having a pierceable, self-sealing diaphragm positioned therein;
- an outlet for coupling to a conduit for connection to a patient;
- and a main body portion having a chamber coupling said first, second and third inlets to said outlet, said first inlet and said outlet being oppositely positioned and said second and third inlets being oppositely positioned, said second inlet and said outlet being substantially coaxial, and said third inlet being substantially coaxial with said first inlet.
An injection site for enabling the introduction of a supplementary parenteral fluid into a primary parenteral fluid being transmitted from a source to a patient, the improvement comprising:
- a body having first and second ports for use either as an inlet or a outlet for passing said primary parenteral fluid through said body from said first port to said second port or for passing said primary parenteral fluid through said body from said second port to said first port, and pierceable diaphragm means enabling said supplementary fluid to be injection into said primary fluid at a position in said body intermediate said ports, said pierceable diaphragm means including a first diaphragm coaxially positioned with respect to said first port and a second diaphragm coaxially positioned with respect to said second port.
An injection site for location between a parenteral source of fluid and a patient, which comprises:
- a main body portion;
- a first inlet on one side of said body portion for coupling to a conduit from a first liquid container;
- a second inlet on said one side of said body portion, laterally displaced from said first inlet, and having a pierceable, self-sealing diaphragm positioned therein and held under compression;
- an outlet on the opposite side of said body portion and laterally displaced from said inlet for coupling to a conduit connected to a patient, a third inlet on said opposite side of said body portion and laterally displaced from said outlet, said third inlet having a pierceable, self-sealing diaphragm positioned therein and held under compression;
- said main body portion having a chamber coupling said first, second and third inlets and said outlet, said second inlet being positioned for injection from said first side and said third inlet being positioned for injection from said opposite side.
An injection site for location between a parenteral source of fluid and a patient, which comprises:
- a main body portion, said main body portion comprising a first member and a second member, said first member having a first inlet and means laterally displaced from said first inlet receiving a pierceable diaphragm, said second member having an outlet and means laterally displaced from said outlet receiving a pierceable diaphragm, said first and second members being interconnectable with each other, said first and second members each carrying on its connecting side a bead extending substantially through one-half the distance around said side and a recess extending from one end of the bead to the other end of the bead, with said recess being symmetrical with said bead, whereby said first member and said second member can be interconnected with each other with the bead from the first member engaging the recess of the second member and the bead of the second member engaging the recess of the first member.
