摘要:
An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes either an elastic distendable membrane, or a thin barrier member which, in cooperation with a thin planar base defines a fluid chamber having a fluid outlet. The apparatus includes an internal stored energy source which functions to controllably expel the medicinal agents from the apparatus. The stored energy source may comprise either a distendable elastomeric membrane of an expandable sponge like cellular mass.

An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, which, in cooperation with a thin planar base defines a fluid chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet.
摘要:
A device for intermixing a first component, such as a parenteral fluid with a second component, such as an immobilized drug carried by a scaffold to form a beneficial agent which, following the mixing step, can be dispensed directly from the device for infusion into a patient. The device includes novel mechanisms for mateably interconnecting a container, such as a glass vial containing the first component with a housing having a fluid outlet which houses a sealed container containing the second component, and then for controllably mixing the components under sterile conditions to form an injectable solution which is automatically dispensed through the fluid outlet of the device.
摘要:
An apparatus for controllably intermixing two or more components in a sterile, closed environment to produce a flowable substance and then for expelling the flowable substance from the apparatus at a precisely controlled rate. The apparatus is particularly useful for medical applications and includes a dispenser portion with its own stored energy member for dispensing the flowable mixture and a coupling mechanism for coupling a drug vial to the dispenser portion for the controlled mixing of a medicament contained within the drug vial with a diluent stored within the dispenser portion of the apparatus via a sterile pathway.

摘要:
An infusion apparatus for delivering beneficial agents, such as drugs to a patient at substantially a constant rate. The device uniquely includes a manifold system to which a plurality of elastomeric bladder type infusion devices are connected. Each infusion device includes an internally disposed functional substrate which carries the beneficial agent so that it can be mixed with the fluid as the fluid is being introduced into the device to distend the bladder to make it an energy source for controllably dispensing the solution mixture to the manifold system and thence to a patient. The manifold system includes control valves which permit fluid from selected infusion devices to be disposed from the apparatus.
摘要:
A liquid delivery apparatus including a housing having internal walls that define a chamber, a support disposed within the housing and having a central portion, an edge portion circumscribing the central portion and including a liquid passageway in communication with the chamber of the housing. The liquid passageway has an inlet and an outlet.

摘要:
A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as, antibiotics, oncolytics, hormones, steroids, blood clotting agents, analgesics, and like medicinal agents from prefilled containers at a uniform rate. The dispenser uniquely includes a stored energy source that is provided in the form of a substantially constant-force, compressible-expandable wave spring that provides the force necessary to continuously and uniformly expel fluid from the device reservoir. The device further includes a fluid flow control assembly that precisely controls the flow of medicament solution to the patient.
