A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

An arterial blood module (16) that is removably connectable to an arterial blood collection element (14) is disclosed. The arterial blood module includes a housing (30), a needle (32), a cap (34) removably securable over the needle, a mixing chamber (36), and a safety shield (38) engaged with a portion of the housing and transitionable from a first shield position in which a portion of the needle is exposed to a second shield position in which the needle is shielded by a portion of the safety shield. In one embodiment, the present disclosure includes an arterial blood collection system (10) that includes an arterial blood collection element (14) defining a collection chamber (20) and an arterial blood module (16) removably connectable to a portion of the arterial blood collection element.

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.

A safety needle device includes a housing including a passageway with a needle cannula extending therefrom. A shielding member is movable between a first position in which a puncture tip of the needle cannula is exposed therefrom and a second position in which the puncture tip of the needle cannula is encompassed therein. The shielding member is maintained in the first position against a biasing force which biases the shielding member toward the second position. A fluid and/or a temperature activation material is associated with the shielding member and is adapted to deform upon contact with a fluid medium and/or a certain temperature or temperature range. The fluid medium flowing through the needle cannula causes the fluid activation material to deform, such as through expansion, thereby releasing the shielding member from the first position and allowing a drive member to bias the shielding member toward the second position.

A safety needle device is disclosed comprising a hub, needle cannula, housing, tether, retractable sleeve, locking member and spring element. The tether is slidably disposed in the housing, the tether having a slot with an enlarged first guide path and a narrowed second guide path extending distally from the enlarged first guide path. The retractable sleeve is configured to move between an initial position, retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula.

Needle protector assemblies including needle assemblies and needle protectors for housing used blood collection needles are disclosed. The needle protectors are single-piece protectors that include an open distal end for receiving a needle hub (with a needle mounted thereon). A retaining member locks the needle hub when the needle hub is substantially retracted. A stop engages the needle hub in a fully retracted position such that a needle post is completely contained within an interior chamber of the needle protectors. A viewing slot in the needle protectors is provided.

A biological fluid collection system (10) including a collection module (14) for collecting a small sample of blood and transferring a portion of the sample into a device or instrument for analyzing the sample such as a point-of-care or a near-patient-testing device including blood collection devices for collecting and transferring venous and arterial blood samples are disclosed.

A syringe needle shield (10) and a method of using the syringe needle shield (10) that is configured to enclose a needle el (4) of a syringe (2), the syringe needle shield (10) comprising a proximal end (20) providing access to an inner cavity (50), a distal end (22) including a flange (30), and an outer surface (24) including a plurality of ribs (40) disposed adjacent to the flange (30), each of the plurality of ribs (40) including a substantially flat surface (42) and a concave surface (44), wherein the substantially flat surface (42) is adjacent to the concave surface (44).

A liquid collection-injection needle assembly is provided including a needle cap that accommodates and protects a needle, and that is designed to be used for other purposes as well, so that the needle cap is effectively used, and the number of parts required for assembly is reduced. The assembly includes a needle holding member that holds a needle after needle has been inserted into holding member, and a needle cap that is configured to be connected detachably to a front part of needle holding member, and to protect the exposed portion of needle that is exposed from the needle holding member after needle has been inserted into needle holding member. In the state where needle cap communicates with needle holding member, an end portion of the needle cap is capable of communicating with a rear part of needle holding member.

A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.
