Problems solved by technology

However, the plunger protruding from the syringe barrel makes handling and delivery of the arterial blood collection syringe difficult and special care must be taken not to dislodge the plunger, thus hindering pneumatic tube delivery and increasing the time and resources required to deliver and analyze the collected blood sample

Abstract

A fluid collection assembly (10) and method for use thereof is provided including a fluid collection cartridge (20) having a tubular member (21) with a plunger assembly slidably inserted. The plunger assembly includes a stopper (32) and a plunger rod (31). The stopper and plunger rod are removably interlocked together which enables the plunger rod to exert a force in a distal direction on the stopper and to be removed from the stopper upon the application of a proximal force thereto. The fluid collection assembly is particular useful in the collection of arterial blood. In use, the assembly is primed with a liquid anticoagulant, the plunger rod is removed, and a blood sample is collected with the arterial pressure causing the stopper to travel in a proximal direction along the cartridge.

Description

technical field [0001] The present invention relates to a fluid collection assembly and methods of use thereof, and more particularly to a fluid collection assembly having a removable piston rod for collecting a fluid sample, such as for collecting an arterial blood sample. Background technique [0002] Arterial blood collection syringes are used to draw and collect samples of arterial blood from a patient's body. Once a blood sample is collected, it is subjected to diagnostic analysis for gases, electrolytes, metabolites, and other elements indicative of the patient's condition. Various types of syringes have been designed for collecting arterial blood samples, mainly comprising elements from hypodermic syringes, namely plastic or glass syringe barrels, sealing elastomer stoppers and plunger rods. Additionally, some arterial blood collection syringes include self-sealing filters that allow air to escape through the syringe while preventing blood from passing during blood c...
