An apparatus includes a transfer adapter, a puncture member, a disinfection member, and a fluid reservoir. The transfer adapter has a proximal end portion and a distal end portion, and defines an inner volume configured to receive the puncture member. The transfer adapter is coupled to the disinfection member. The distal end portion of the transfer adapter includes a port fluidically coupled to the puncture member and configured to be placed in fluid communication with a bodily-fluid of a patient. The proximal end portion is configured to receive a portion of the fluid reservoir to allow the fluid reservoir to be moved within the inner volume between a first position, in which a surface of the fluid reservoir is placed in contact with the disinfection member, and a second position, in which the puncture member punctures the surface to place the puncture member in fluid communication with the fluid reservoir.

A flow restriction device may include a proximal housing including an internal fluid channel, a distal housing including an internal fluid channel, and an intermediate housing interposed between the proximal and distal housings. The intermediate housing may include an internal chamber, and a slider reciprocally disposed in the internal chamber. The slider may include an internal fluid channel and a seal overlaying an outer surface of slider excluding the fluid channel, and may be reciprocally movable between (i) a first position where the internal fluid channel of the slider is axially aligned with the internal fluid channels of the proximal and distal housings to allow a fluid to flow therethrough, and (ii) a second position where the internal fluid channel of the slider is not aligned with the internal fluid channels of the proximal and distal housings and the seal blocks fluid connection between the proximal and distal housings.

A blood collection apparatus comprising: (i) a test tube for storing blood extracted from a patient, the test tube comprising a vacuum facilitating an extraction of blood; (ii) a heat transfer element encapsulating the test tube and storing at least two reagents capable of initiating a heat transfer process contemporaneously with the extraction of the blood, the heat transfer element further comprising a fracturable element that when fractured enables the at least two reagents to initiate the heat transfer process; and (iii) an insulation element encapsulating the heat transfer element, the insulation element inhibiting a loss of a temperature change of the blood, wherein test tube is removable, contemporaneously with an initiation of a blood test, from the insulation element encapsulating the heat transfer element, and wherein the apparatus comprises a circumference suitable to be mated with a general purpose test tube needle holder.

Peripheral intravenous catheter assemblies with capabilities for both blood sampling and catheterization can have a blood collection holder with a needle hub attached to a catheter hub. The combination catheter assembly and blood sampling holder can be called a catheter and holder assembly. Blood sampling can be done directly through the needle and the blood collection holder after cannulation. After blood sampling, the blood collection holder and the needle can be removed, leaving the catheter hub with the patient for IV infusion. The catheter hub can be a straight catheter hub or can include a side fluid port for use in as an integrated IVC.

A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.

A system for verifying a sample volume includes a sample reservoir and a volumetric verification device. The sample reservoir defines an inner volume and is configured to receive a volume of bodily fluid. The inner volume of the sample reservoir contains an additive. The volumetric verification device includes a first indicator and a second indicator. The volumetric verification device is configured to selectively engage the sample reservoir to (1) place the first indicator in a first position along a length of the sample reservoir such that the first indicator is substantially aligned with a surface and/or meniscus of the additive and (2) place the second indicator in a second position along the length of the sample reservoir such that the second indicator is substantially aligned with a predetermined fill volume when bodily fluid is transferred to the inner volume.

A bodily-fluid transfer 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 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.

A method for analyzing thrombogenic capacity or blood coagulation capacity, the method comprising adding calcium, a blood coagulation factor XII (FXII) inhibitor, and a kallikrein inhibitor to blood collected with a blood collection tube containing sodium citrate, to allow initiation of blood coagulation reaction, is provided. Preferably, heparin, heparan sulfate, and tissue factor are further added to the blood, and thrombogenic capacity or blood coagulation capacity is analyzed.
