A transfer device includes an introducer coupleable to a peripheral intravenous catheter, with the introducer having a proximal end portion and a distal end portion, a catheter having a proximal end portion and a distal end portion and defining a lumen, a secondary catheter having a proximal end portion and a distal end portion and defining a lumen, and an actuator receiving the proximal end portion of the catheter and the distal end portion of the secondary catheter. The actuator is moveable within introducer from a first position where the distal end portion of the catheter is positioned within the introducer to a second position where the distal end portion of the catheter is positioned outside of the introducer.

The present disclosure is a blood collection assembly that has a needle assembly fixedly coupled to a finger-activated actuator and tubing and the needle assembly has a needle. Further, the blood collection assembly has a hub that houses the needle assembly and the hub has a channel in a top surface of the hub. Additionally, the channel slidably engages the finger-activated actuator such that when the finger-activated actuator is moved from a distal end of the hub to a proximal end of the hub the needle retracts within the hub.

A shieldable needle device (12) with a needle cannula (28), a hub (44) supporting the needle cannula, and a tip guard (24) axially movable along the needle cannula where, upon transition, the tip guard protectively surrounds the distal end (42) of the needle cannula. The needle device includes a pair of wings (60) extending laterally from opposing sides of the tip guard and connected to the hub. The pair of wings are transitionable between a first position and a second position, wherein transition of the pair of wings advances the tip guard from a proximal position to a shielding distal position. The wings include protrusions (66) which cause the longitudinal axis of the needle cannula to become offset from the opening (52) of the tip guard during advancement of the tip guard preventing the needle cannula from being reinserted through the tip guard after the tip guard has been transitioned to the distal position.

An apparatus comprises a housing, a testing member rotatably mounted in the housing, a lancet protruding from an edge of the testing member and having a piercing end, and a cover configured to cover at least the piercing end of the lancet and to be displaced from the piercing end of the lancet during actuation of the testing member.

The invention relates to a safety needle device, for a medical instrument, to insert a needle into a patient's body to a determined insertion depth. The safety needle device, in two variants with a fixed insertion depth and with an insertion depth adjustment, comprises a hub, a needle, a protecting shield, longitudinal resilient means, transverse resilient means, a housing, and is provided with different technical means configured to cooperate with each other in order to perform different functions of the device. The safety needle device enables to control a state of use of the device, wherein the device is a disposable one and it ensures its user a protection against an accidental or intentional prick of the needle before and after the due use of the device for the purpose for which it is intended.

A needle guard (10) has an elongate concave channel member (22) having a longitudinally extending opening between two longitudinally extending sides (30) and defining part of a passageway (36) having a forward end (40) and a rear end (64). A tongue member (24), in an open position, extends longitudinally adjacent the opening and defines at least one slot (34) between itself and at least one of the sides (30) adapted to receive at least one wing of a winged needle block. The tongue member (24) is movable to a closed position to lie within the channel member (22) to close, block or substantially close or block the passageway (36).

Further, the blood collection assembly has a hub that houses the needle assembly and the hub has a channel in a top surface of the hub. Additionally, the channel slidably engages the finger-activated actuator such that when the finger-activated actuator is moved from a distal end of the hub to a proximal end of the hub the needle retracts within the hub.

A needle assembly. The needle assembly enabling the analysis of fluid trapped in a flashback chamber after an insertion needle has been inserted into a patient's vein.

An apparatus includes a catheter, an introducer, and an actuator. A distal end portion of the introducer is configured to couple to an indwelling peripheral intravenous line. The actuator is movably coupled to the introducer and is configured to move the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which a distal end portion of the catheter is distal to the introducer. A first portion of the actuator is disposed outside of the introducer and in contact with an outer surface of the introducer such that (1) a longitudinal axis defined by a second portion of the actuator is nonparallel to a longitudinal axis defined by the introducer and (2) the second portion of the actuator exerts a force on a proximal end portion of the catheter operable to increase an internal stress within a portion of the catheter.
