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.

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.
摘要:
A multi-port syringe with a fluid chamber in communication with an inlet valve assembly and an outlet valve assembly disposed intermediate the fluid chamber and the inlet valve assembly, the inlet valve assembly has an inlet valve member operable in an open position and a closed position, the inlet valve member being biased in a closed position by a resilient member. The outlet valve assembly has an outlet valve member operable between a closed position and an open position, and the outlet valve member is maintained in a closed position by a sealing member, and includes anchoring member engaging the outlet valve assembly. With the outlet valve member in the closed position, the inlet valve member is forced open by compressing the resilient member, thus allowing fluid into the chamber, and with the fluid chamber primed and the inlet valve member in a closed position, the outlet valve member is forced open by disengaging the anchoring member and defeating the sealing member to allow fluid discharge from the chamber.
摘要:
A non-luer apparatus for controlled flow of medical fluid materials for use as an adapter in a covered outlet of a medical fluid container, has a body with a hollow interior, a first open end adapted for attachment with the medical fluid container outlet, and a second open end adapted for fit with a medical accessory. The first open end also has a piercing portion for piercing the covered outlet. The second open end further includes an upstanding circumferential wall and associated retaining means for releasable attachment with the medical accessory. A fluid flow control means is disposed within the body to control the flow of medical fluid materials between the medical fluid container and the medical accessory where the fluid flow control means is motivated to open or close fluid communication when the medical accessory is attached or disengaged from the second open end.
摘要:
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. The valve member is motivated to open fluid communication between the medical fluid container and the medical accessory when the medical accessory is attached to the second open end and the valve member is motivated to close fluid communication between the medical fluid container and the medical accessory when the medical accessory is disengaged from the second open end.
摘要:
An apparatus for controlled flow of fluid materials for use with medical accessories has a first housing with a body, a first open end, a second open end, and a hollow interior. The second end fits with a first medical accessory for flow of fluid materials from the first medical accessory. A fluid flow control means is disposed within the housing for controlling the flow of fluid materials through the hollow interior from the first medical accessory. The apparatus also has a second housing with an open end, a first open end, a hollow interior, and a second open end having an axial bore coaxial with the hollow interior of the first housing. The second end of the second housing fits with the first open end of the first housing. The first open end of the second housing fits with a second medical accessory, whereby the second medical accessory receives fluid materials from the first medical accessory by way of the hollow interior of the body.
