Abstract: A multiple-draw syringe for extraction of a fluid into at least one fluid container comprising a cylindrical body having a distal end and an open proximal end, a hollow needle extending from the distal end, a piston sealably engaging and slidable along an interior wall of the cylindrical body, a ball check valve, a plunger for moving the piston proximally or distally within the cylindrical body, and a conduit extending through the piston to an enclosed fluid collection receptacle. The distal end includes a first chamber provided with a fluid inlet at one end and a fluid outlet at an opposite end. The first chamber has a conical sidewall adjacent the fluid inlet and a plurality of radially spaced stems adjacent the fluid outlet. The distal end is open to the flow of a fluid into the cylindrical body through the first chamber when the syringe is in use.

Abstract: A tracheostomy tube assembly, particularly for pediatric use, is provided. The tracheostomy tube assembly includes a tracheostomy tube having an adjustable length and being adapted for insertion into the trachea through an opening in a patient's neck. The assembly further includes a neck collar adapted to fit on the exterior of the patient's neck. The neck collar has an opening through which the tracheostomy tube passes.
