A syringe assembly includes (i) a syringe with a cylindrical body, luer tip at a first end, finger grip at a second end and a cannula extending from the luer tip into the cylindrical body, and (ii) a plunger unit having an adapter portion, receiving cavity, finger grip and piston. A channel extends the length of the adapter portion to receive the cannula in one end and a variety of connectors, valves and/or syringes in a second end. The end of the channel accessible in the receiving cavity mates with or engages any number of commercially available valves, connectors and/or syringes while the luer tip similarly connects to any number of valves, catheters, connectors, etc., depending on the task being undertaken with the syringe assembly.

Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.

An ergonomic suction syringe and method for performing medical procedures in which suction is generated and can be delivered to a medical device by a single-handed compression motion, with suction actuated by forward motion of a piston into a cylinder, and in which suction can be maintained essentially permanently once activated without any further effort by the operator, even hands-free.

A device is used in combination with a fluid pressure source and a replaceable sampling tube having a pointed cannula section and a hollow for capillary blood collection. The device is provided with: a body defining a bore extending along an axis; a first flow path in fluid communication with the fluid pressure source; a rotor fitting in the bore and being capable of spinning in both directions about the axis; a boss section extending along the axis and so dimensioned as to rotatably support the sampling tube coaxially with the axis and expose the cannula section out of the boss section; and a detachable fastening binding the sampling tube to the rotor so as to set the sampling tube into rotation concentric with the axis and establish fluid communication between the first flow path and the hollow of the sampling tube.

Medical device assemblies capable of aspirating liquid into a syringe barrel or other medical devices while evacuating any air from the syringe are described. An exemplary medical device includes a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within either the stopper or the plunger rod. Described is a medical device including a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within chamber between the stopper and plunger rod wherein the plunger rod includes a sealing edge and is moveable relative to the stopper. Exemplary medical devices may include a vent for allowing air that permeates through the porous portion to escape to atmosphere. Methods for aspirating a syringe barrel with a liquid are also provided.

Disclosed is an apparatus and method for accessing blood located within a flash chamber of an IV catheter insertion device, the apparatus is a separate from the IV catheter insertion device assembly and sized to be attached to a structure of the IV catheter insertion device to secure it thereto (the separate apparatus may be a portion of a protective cover which shields the needle of the device during shipment, a cover which is removed prior to use of the IV catheter insertion device to expose the needle). Once in position, movement of the device from its rearward position to a forward position advances the plunger into contact with the flash chamber plug (or flash filter). Further advancement of the device then advances the flash chamber filter into flash chamber which expresses blood from the flash chamber of the IV catheter insertion device

A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter extending distally from a distal end of the catheter adapter. The catheter system may also include a needle assembly, which may include a needle hub and an introducer needle. The needle hub may include: a distal end coupled to the proximal end of the catheter adapter; a proximal end; a wall disposed between the distal end of the needle hub and the proximal end of the needle hub; and a flashback chamber proximate the wall. The introducer needle may be press-fit within a through-hole of the wall. The catheter system may also include a plug coupled to the proximal end of the needle hub. A blood collection device may be coupled to a proximal end of the plug to collect blood from a patient.
