Syringe-Carpule Assembly
US Patent:
2010010, Apr 29, 2010
Filed:
Oct 28, 2009
Appl. No.:
12/607498
Inventors:
Steven Schulhof - Teaneck NJ, US
International Classification:
A61M 5/32
US Classification:
604518, 604 92
Abstract:
A syringe-carpule assembly comprising first and second carpules, a housing holding the first and second carpules in an end-to-end relationship, an outer hollow plunger rod supported by and slidable relative to the housing, and an inner hollow rod having first and second openings and being slidably arranged inside the outer hollow plunger rod. The inner hollow rod is slidable between first and second positions. The inner hollow rod in the first position has the first opening disposed within the first carpule and the second opening disposed within the second carpule. This allows liquid solvent in the second carpule to flow into the first carpule, which comprises an evacuated chamber containing solid matter that dissolves in the presence of that solvent to form a mixture. The second carpule is then removed and the mixture in the first carpule is injected into the patient.
Stopper/Plunger For Carpules Of Syringe-Carpule Assembly
US Patent:

Filed:
Aug 1, 2011

Assignee:
SYNCHROJET LLC - Teaneck NJ
International Classification:
A61M 5/31
US Classification:
604520, 604187, 604200
Abstract:
An elastomeric stopper that can be partially inserted in a rear opening of a glass carpule and that also serves, when fully inserted in the carpule, as a plunger for forcing fluid inside the carpule out through a front opening thereof. The stopper has a thin central portion at its front end that can be readily pierced by a pointed hollow rod of a syringe. When the hollow rod is removed, the elastomeric material of the thin central portion will “seal itself” around the puncture hole. The stopper also has a retractable lip at its rear end that allows the entirety of the stopper to be pushed down and into a fluid-containing glass carpule, thereby acting as a plunger and ejecting fluid from the front opening of the carpule.
