Abstract: Disclosed herein is a syringe assembly for discharging gaseous materials from a syringe, comprising an elongate container with a plunger slidably and sealingly engaged therein to form a fluid material receiving cavity, the container further comprising an outlet for dispensing fluid materials from the cavity; the plunger including transfer means for transferring gas constituents from the cavity to a region outside the cavity.

Abstract: A syringe including a releasable lock means for allowing discharge of a treated biological fluid sample to the patient in response to a release signal to the releasable lock means. The release signal is issued following a positive outcome from a verification process dependent upon temporal data from certain events in the collection, treatment and delivery of the biological fluid sample, and identity data of the patient and the second device with the treated biological fluid.

Abstract: A device for controlling the collection and delivery of materials to a patient, the device has a dispenser-engaging portion, the dispenser-engaging portion being operable in a release position to receive a materials dispenser when the dispenser is in a materials-containing configuration, the dispenser-engaging portion being operable in a lock condition for locking the dispenser therewith, and access control means for controlling the release and lock positions according to a material transaction condition.

Abstract: A syringe comprising a chamber and material transfer portion with a cavity in communication with an inlet portion and an outlet portion. The inlet portion includes an inlet valve means for controlling material flow therethrough, and the material transfer portion includes a control valve operable between a first position to control the inflow of material from the inlet portion to the material container portion, and a second position to control the flow of material from the chamber to the outlet portion, and the outlet portion includes a releasable lock means for allowing discharge the material through the outlet portion.

Abstract: A syringe includes a releasable lock means for allowing discharge of a treated biological fluid sample to the patient in response to a release signal to the releasable lock means. The release signal is issued following a positive outcome from a verification process dependent upon temporal data from certain events in the collection, treatment and delivery of the biological fluid sample, and identity data of the patient and the syringe with the treated biological fluid.

Abstract: A vessel having a chamber for receiving an untreated material sample, a chamber inlet for releasably mounting a first syringe and establish a dedicated first fluid coupling therewith to dispense an untreated material sample to the chamber; a chamber outlet for releasably mounting a second syringe and establish a dedicated second fluid coupling with the chamber outlet to dispense a treated material sample following treatment to the second syringe; a gas inlet port coupled to an inlet conduit for carrying at least one gas into the chamber; a gas outlet port coupled to an outlet conduit for carrying at least one gas from the chamber, and a temperature sensor.

Abstract: A system for the collection, treatment and delivery of an autologous blood sample, comprising a first syringe for drawing an untreated blood sample from a patient, a blood sample treatment chamber having a chamber inlet for receiving untreated blood from the first syringe and chamber outlet for passage of treated blood to a second syringe coupled thereto. The second syringe includes a releasable lock means for allowing discharge of the treated blood to the patient in response to a release signal. The release signal is issued following a positive outcome from a verification process dependent upon temporal data from certain events in the collection, treatment and delivery of the blood sample, and identity data of the patient and the second syringe with the treated blood.

Abstract: An apparatus for controlled flow of medical fluid materials for use as an adapter in place of a septum in an outlet of a medical fluid container, has a body with a hollow interior, a first open end adapted for fluid tight fit with the outlet of the medical fluid container, and a second open end adapted for fit with a medical accessory. A fluid flow control means is disposed with the body for controlling the flow of medical fluid materials through the hollow interior between the medical fluid container and the medical accessory. The fluid flow control means comprises a valve member, a valve seat, and biasing means operating on the valve member to bias the valve member against the valve seat for fluid tight fit.

Abstract: A medical delivery device comprising an elongate body having a plunger slidably and sealingly engaged to form a cavity to receive fluid materials and a first outlet disposed at an end of said body and has a male luer end portion and a valve assembly is disposed within the first outlet. The valve assembly has a valve means movable between an open position and a closed position and biasing means for biasing the valve means to a closed position. Actuating means are disposed within the male luer end portion and coupled to the valve means such that the valve means is movable to an open position when a female luer end portion of a medical accessory is coupled with the male luer end portion. A second outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the environment to said cavity under the action of the plunger.

Abstract: Disclosed herein is a system for the collection, treatment and delivery of an autologous blood sample, comprising a first syringe having a first body portion. A first sample transfer portion has a first syringe inlet for drawing an untreated blood sample from a patient and a first syringe outlet for dispensing the untreated blood sample. A blood sample treatment chamber having a chamber inlet, the first syringe outlet being operable to establish a dedicated first fluid coupling with the chamber inlet to dispense the untreated blood sample to the blood sample treatment chamber. The blood sample treatment chamber having a chamber outlet for dispensing a treated blood sample following treatment. The second syringe has a second body portion and a second sample transfer portion, the second sample transfer portion having a passage with a first access location which is operable to form a dedicated second fluid coupling with the chamber outlet.

Abstract: A medical treatment process and system, in which a patient fluid is subjected to extracorporeal handling and treatment prior to administration to the patient, is provided. The system includes two or more treatment units which successively handle the fluid, and a token associated with the patient. The token includes a patient identification and, as the treatment proceeds, more information is added to the token as the fluid moves around the system until the token contains a record of the treatment conducted on the sample, the times of various treatments, and a verification that treatment has been conducted in accordance with pre-determined criteria. The token, provided it contains information verifying the identity of the patient and treatment according to specification, allows administration of the treated fluid to the patient and provides an audit record of the treatment.
