US Classification:

604192, 604110, 604198

Abstract:

A fixed needle syringe has a syringe barrel with its distal portion modified to accept a needle protective housing. In particular, the distal portion is formed with the a groove dimensioned to accept a collar that is attached to the housing. The inside surface of the collar is provided with a number of flanges that fit within the groove formed at the distal portion of the syringe barrel of the fixed needle syringe. Protrusions are provided at the inside surface of the collar to frictionally act against the syringe barrel, so that the needle protective housing does not freely rotate, but is rotatable relative to the syringe barrel by the application of a predetermined torque to either the collar or the housing attached thereto. An internal hook is provided in the housing to grasp the needle of the syringe, when the housing is pivoted to cover the needle extending from the needle hub of the syringe. Coacting locking members are provided at the base of the housing and the outside of the collar for fixedly retaining the housing relative to the collar, once the housing has been pivoted along the alignment position of the syringe.

US Classification:

604132, 604257

Abstract:

A fluid reservoir for a medical infusion system includes an expandable elastomeric bladder defining a chamber for receiving and containing a volume of therapeutic substance and exerting pressure thereon to dispense the therapeutic substance from the bladder. The bladder has preferably a single port formed through the thickness thereof. A bi-directional valve is in fluid communication with the chamber of the elastomeric bladder and is used for filling the bladder chamber with the therapeutic substance and for connecting to a catheter assembly for dispensing the therapeutic substance to a patient undergoing treatment. The single port of the elastomeric bladder is connected to a medical grade flexible tubing, which is also connected to the bi-directional valve.
