摘要:
A syringe-based device includes a housing, a pre-sample reservoir, and an actuator. The housing defines an inner volume between a substantially open proximal end portion and a distal end portion that includes a port couplable to a lumen-defining device. The pre-sample reservoir is fluidically couplable to the port to receive and isolate a first volume of bodily fluid. The actuator is at least partially disposed in the inner volume and has a proximal end portion that includes an engagement portion and a distal end portion that includes a sealing member. The engagement portion is configured to allow a user to selectively move the actuator between a first configuration such that bodily fluid can flow from the port to the pre-sample reservoir, and a second configuration such that bodily fluid can flow from the port to a sample reservoir defined at least in part by the sealing member and the housing.

An apparatus includes a housing, defining an inner volume, and an actuator mechanism movably disposed therein. The actuator mechanism is configured to be transitioned from a first configuration to a second configuration to define a pre-sample reservoir fluidically couplable to receive a pre-sample volume of bodily-fluid via an inlet port of the housing. The actuator mechanism is movable from a first position to a second position within the housing after the pre-sample reservoir receives the pre-sample volume such that the housing and the actuator mechanism collectively define a sample reservoir to receive a sample volume of bodily-fluid via the inlet port. The outlet port is in fluid communication with the sample reservoir and is configured to be fluidically coupled to an external fluid reservoir after the sample volume is disposed in the sample reservoir to transfer at least a portion of the sample volume into the external fluid reservoir.

A method for delivering a fluid to an animal with a drug delivery device without causing contamination to the drug delivery device. The drug delivery device used by the method may comprise a fluid subsystem with a switching device, disposable syringes, fluid reservoirs, disposable tubing, and a catheter. In one embodiment, the method allows a user to deliver multiple drugs to an animal without contaminating the valves that control the flow of fluid.

Bodily fluid sample collection systems, devices, and method are provided. The device may comprise a first portion comprising at least a sample collection channel configured to draw the fluid sample into the sample collection channel via a first type of motive force. The sample collection device may include a second portion comprising a sample container for receiving the bodily fluid sample collected in the sample collection channel, the sample container operably engagable to be in fluid communication with the collection channel, whereupon when fluid communication is established, the container provides a second motive force different from the first motive force to move a majority of the bodily fluid sample from the channel into the container.
摘要:
A specimen mixing and transfer device adapted to receive a sample is disclosed. The specimen mixing and transfer device includes a housing, a material including pores that is disposed within the housing, and a dry anticoagulant powder within the pores of the material. In one embodiment, the material is a sponge material. In other embodiments, the material is an open cell foam. In one embodiment, the material is treated with an anticoagulant to form a dry anticoagulant powder finely distributed throughout the pores of the material. A blood sample may be received within the specimen mixing and transfer device. The blood sample is exposed to and mixes with the anticoagulant powder while passing through the material.
摘要:
A system with three nested syringes that allows for either a larger volume of ACP, or a larger combined output of PRP (platelet rich plasma) and PPP (platelet poor plasma). The different outputs are based upon different centrifuge spin regimes. The system of the present invention produces up to 15mL of ACP, or 3mL of PRP plus 25mL of PPP. The system of the present invention solves the problem of a larger volume of ACP and with a higher cellular concentration. The multi-syringe system allows for the connection of two or more additional syringes. The fractions may be extracted with the multi-syringe system of the present invention at different sequential times, or at the same time.
