  • Patent number: 10835680
    Abstract: A bladder syringe for a fluid delivery system includes a cylindrical body, a cap-bladder assembly, a plunger element disposed in the cylindrical body, and a mounting assembly to secure the cap-bladder assembly to the cylindrical body. The cylindrical body has a distal end and a proximal end and defines a throughbore. The cap-bladder assembly is adapted for connection to the distal end of the cylindrical body, and includes a cap body and a bladder. The cap body defines an interior cavity and a distal discharge conduit and is adapted to engage the distal end of the cylindrical body. A disc-shaped bladder is disposed within the interior cavity and typically includes a central membrane portion. The plunger element is disposed in the throughbore of the cylindrical body and is vented to enable evacuation of the space between the plunger element and the cap-bladder assembly in the cylindrical body.

  • Publication number: 20200222634
    Abstract: A syringe for a fluid delivery system includes a pressure jacket having a distal end, a proximal end, and a throughbore therebetween. The syringe further includes a rolling diaphragm having a proximal end with an end wall for engaging a plunger, a distal end received within the throughbore of the pressure jacket. The distal end of the rolling diaphragm has a nozzle and a sidewall extending between the proximal end and the distal end of the rolling diaphragm along a longitudinal axis. At least a portion of one of the sidewall and the end wall has non-uniform thickness. At least a portion of the sidewall is flexible and rolls upon itself when acted upon by the plunger such that an outer surface of the sidewall at a folding region is folded in a radially inward direction as the plunger is advanced from the proximal end to the distal end of the rolling diaphragm.

  • Publication number: 20140276452
    Abstract: Spikes, spike and tubing sets and fluid administrations systems are disclosed. A fluid administration system may include a fluid container having a septum and containing a fluid, a spike, and a flexible tube. The spike may include a hollow access tube extending from a proximal end to a distal end of the spike, a platform surrounding the hollow access tube at a location between the distal and proximal ends, and a sharp tip-end at the distal end. The access tube has a central bore and a sidewall, each extending from the proximal to the distal end. The access tube may include at least one opening extending from the central bore to the sidewall and located between the platform and the sharp tip-end. The flexible tube is configured to connect to the access tube and to deliver fluid from the access tube to a fluid administration location.
