SYRINGE FOR OBTAINING A TARGET VOLUME OF BLOOD
20230008783 · 2023-01-12 ·

A syringe for obtaining a target volume of blood is presented. The syringe (1) comprises a barrel (2), wherein a plunger (4) is arranged within the barrel (2) to be displaceable along a displacement direction (X). Furthermore the barrel (2) and the plunger (4) together provide for a first stop (20) and second stop (22), wherein the first stop (20) is configured for positioning a filter (100) at a predetermined location along the displacement direction (X) thereby defining a target volume of blood and a buffer volume. Moreover, the second stop (22) is configured to stop the plunger (4) from expelling more than the buffer volume from the syringe (1) for obtaining the target volume of blood when the plunger (4) is pushed towards the distal end (30) of the syringe (1) along the displacement direction (X). In addition, the syringe (1) facilitates that the syringe (1) fills itself with the target volume of blood by a self-filling procedure using blood that is under pressure, like arterial blood, and using the filter (100) located in the plunger (4).

SENSOR APPLICATOR ASSEMBLY FOR CONTINUOUS GLUCOSE MONITORING SYSTEM

Fluid transfer device, system and method

A fluid transfer device includes a syringe barrel having a chamber, a first plunger slidably movable inside the chamber, and a second plunger slidably movable inside the chamber. The distal end portion of the first plunger is engageable with the proximal end portion of the second plunger such that when the distal end portion of the first plunger and the proximal end portion of the second plunger are engaged, the second plunger is movable by the first plunger. A check valve may be incorporated into the distal end portion of the second plunger to allow a fluid to pass therethrough in a direction towards the proximal end portion of the second plunger and prevent a fluid to pass therethrough in a reverse direction. A fluid transfer assembly and a sampling method are also described.

Syringe-based fluid diversion mechanism for bodily fluid sampling

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.

APPARATUS AND METHOD FOR DRAWING BLOOD AND OTHER BODILY FLUIDS
20220322983 · 2022-10-13 ·

An adapter for a syringe having a barrel, a pair of syringe flanges secured to the barrel, and a plunger with a plunger top, the plunger being slidably disposed within the barrel, the adapter having a barrel guide configured to movably surround the barrel, a plunger lock configured to secure the plunger to the adapter, a support body disposed between and associated with the barrel guide and the plunger lock and a front grip associated with the barrel guide. By compressing the syringe flanges and the front grip toward each other, the barrel may travel forward through the barrel guide, thus drawing fluid into the syringe. The adapter, by allowing a compression force to be used to draw a fluid into the syringe, allows an individual to quickly and easily perform a blood draw or other fluid drawing operation with one hand, removing the need for a second user.
