Filed:

May 4, 1999

Appl. No.:

09/304934

Inventors:

David M. Reilly - Glenshaw PA
Alan D. Hirschman - Glenshaw PA
Eugene A. Gelblum - Mt. Lebanon PA

Assignee:

Medrad, Inc. - Indianola PA

International Classification:

A61M 3700

US Classification:

604131, 604154, 604151, 128DIG 1

Abstract:

The pressure jacket systems of the invention are used to permit the front loading and removal of a syringe from an injector and include a first jacket segment and a second jacket segment surrounding the exterior surface of the syringe, interior surfaces comformable to the exterior surface of the syringe, a mechanism which allows movement of the first jacket segment in relation to the second jacket segment to permit insertion and removal of the syringe from the pressure jacket, and a mechanism for securing the first and second jacket segments in a fixed relationship upon insertion of the syringe.

Abstract:

A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.

International Classification:

A61M 500

US Classification:

604181

Abstract:

A syringe includes a body and a plunger disposed therein. The body includes a nozzle formed therein and at least one hub member connected thereto or integrally formed thereon for holding an end of a connector tube. The connector tube includes two ends, each end preferably being connected to a respective hub member to retain the connector tube in contact with the syringe. Preferably, the syringe and the connector tube are packaged in a pre-connected condition for ease of use by the customer. Furthermore, flexible inlet tubing for connection to a syringe for filling the syringe with contrast media, for example, is described. The inlet tubing permits filling of the syringe from either a bag or a bottle and may remain attached to the syringe so that it forms at least a part of the connection to the patient. In addition, an apparatus for facilitating the purge of air from a connector tube that will ultimately be connected between a syringe and a patient is described. The apparatus includes a purging tube connected to the distal end of the connector tubing from the syringe.
