A needle set includes a needle guard and a winged needle. The needle guard has upper and lower jaws, each of the upper and lower jaws defining a channel and coming together at a hinge. The upper and lower jaws are separated by slots in sides of the needle guard, which slots divide the sides into upper and lower side walls, respectively. The winged needle can be inserted between the upper and lower jaws, with wings of the winged needle passing through the slots. The hinge has an opening and a tube connected to the winged needle passes through the opening.

An inserting device includes a main casing, a bracket, a first elastic component, an inserting assembly and a second elastic component. The main casing has a position-limiting portion and a first holding portion. The bracket is disposed in the main casing and has a second holding portion. The first elastic component is disposed between the main casing and the bracket, and the first holding portion holds the bracket. The inserting assembly is disposed in the main casing. The second elastic component is disposed between the inserting assembly and the bracket. The position-limiting portion limits the second holding portion, such that the second holding portion holds the inserting assembly on the bracket. When the bracket is released by the first holding portion, the bracket, the second elastic component and the inserting assembly move by the elastic force of the first elastic component, the second holding portion is departed from the position-limiting portion, and the inserting assembly is restored by an elastic force of the second elastic component. Moreover, a blood collection device including the inserting device is also provided.

A precision syringe plunger includes a plunger rod and a separately manufactured plunger arm. The plunger rod includes a base formed at a proximal end of the plunger rod and a first interference fit connector formed below the base. The plunger rod is configured to extend longitudinally into a syringe barrel. The plunger arm includes a second interference fit connector formed at a proximal end of the plunger arm. The second interference fit connector is configured to be irreversibly coupled to the first interference fit connector so that the plunger arm extends longitudinally along an outer surface of the syringe barrel. The plunger arm further includes a distally located projection. The projection is configured to receive an applied force that causes an entirety of the syringe plunger to move relative to the syringe barrel so that the plunger rod is actuated through a portion of the syringe barrel.

A specimen transfer device adapted to receive a blood sample is disclosed. The specimen transfer device includes a housing and an actuation member. A deformable material is disposed within the housing and is deformable from an initial position in which the material is adapted to hold the sample to a deformed position in which at least a portion of the sample is released from the material. A viscoelastic member is disposed within the housing between the material and the housing and between the material and the actuation member. The viscoelastic member is engaged with the actuation member and the material such that movement of the actuation member from a first position to a second position deforms the material from the initial position to the deformed position.

A lancing device with an ejector that is movably retained with a housing in proximity to a lancet and is selectively movable between a home position, a first eject position, an intermediate position defined by contact of the ejector with the lancet, and a second eject position. The ejector is rotatable to move from the home to first eject position and is linearly translatable to move between the first and second eject positions. The ejector includes an arm that extends within the housing and engages the lancet, an exterior portion that is actuated by a user, and a post extending therebetween. The post extends through a slot in the housing which limits the linear movement and direction of the ejector. Upon rotation of the ejector, the arm extends through an opening at the rear of the carriage holding the lancet to permit access to the lancet.

A precision syringe includes a syringe barrel and plunger that has a base, an internal portion, and an external portion. The internal portion of the plunger extends longitudinally into the syringe barrel. The internal portion has a first end coupled to the base and a second end that is configured to push fluid out of and/or suction fluid into the syringe barrel. The external portion extends longitudinally along an outer surface of the syringe barrel. The external portion has a first end coupled to the base and a second end that is configured to receive an applied force that causes the plunger to move relative to the syringe barrel so that the second end of the internal portion is actuated through a portion of the syringe barrel (e.g., to dispense fluid from or suction fluid into the syringe barrel).

An apparatus includes a catheter, an introducer, and an actuator. A distal end portion of the introducer is configured to be coupled to a peripheral intravenous line. The introducer defines an inner volume having a first portion that defines an axis parallel to and offset from an axis defined by a second portion. A first portion of the actuator is movably disposed in the first portion of the inner volume. A second portion of the actuator is movably disposed in the second portion of the inner volume and coupled to the catheter movably disposed in the second portion of the inner volume. The actuator moves the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which at least a portion of the catheter is disposed within the peripheral intravenous line.

A flow restriction device may include a male luer connector portion, a female luer connector portion, a tube, and an overmolded body portion. The male luer connector portion defies a first lumen. The female luer connector portion defines a second lumen. The tube defines a third lumen. The third lumen is in fluid communication with the first lumen and the second lumen. The third lumen has a diameter less than 0.025 inches. The overmolded body portion is formed around the tube.

A collection device (10) which directs a flow of blood into a container (14) and provides a controlled blood flow path that ensures blood flow from a collection site to a collection container is disclosed.

A point-of-care blood collection and dispensing device for use with a luer lock access device, the point-of-care collection and dispensing device including a distal engagement portion, wherein at least a part of the distal engagement portion is configured to engage a needle of the luer lock access device, and a sidewall portion, wherein at least part of the sidewall portion is formed of a flexible material capable of being compressed. The device also includes a fluid chamber configured to hold a blood sample, the fluid chamber bound at least partially by the distal engagement portion and the sidewall portion, as well as an opening, wherein the opening is sized and configured to dispense a small volume of the blood sample held within the fluid chamber when the sidewall portion is compressed.
