Patent number: 11458241Abstract: Implementations described herein include a system for guiding medical waste fluid into a medical waste collection canister. The system includes a manifold and a filter. The manifold includes a top surface and a sidewall extending from the top surface in a first direction. The top surface and the sidewall define an interior chamber of the manifold. The top surface includes an inlet port and a vacuum port disposed therein. The inlet port connects to a source of medical waste fluid and the vacuum port connects to a vacuum source. The manifold can be formed from a first polymer. A filter is positioned within the interior chamber of the manifold and immediately upstream of the vacuum port so as to filter air flowing into the vacuum port. The filter extends away from the top surface of the manifold in the first direction and the filter is formed from a second polymer.Type: GrantFiled: July 24, 2020Date of Patent: October 4, 2022Assignee: Zimmer, Inc.Inventors: Larry C.

Patent number: 8920394Abstract: A suction canister liner including a body portion having a sidewall and a bottom. An annular tapered sealing surface is positioned over the sidewall of the canister liner body portion to allow ease of loading and unloading. The annular tapered sealing surface has a top diameter and a bottom diameter, where the top diameter is greater than the bottom diameter. The canister liner may be placed within the interior of a canister. The canister sidewall includes a vacuum port adapted to communicate with a vacuum source. A lid having a patient port and a suction port engages and removably covers the open top end of the canister liner. The annular tapered sealing surface of the canister liner seals against the interior surface of the rim of the canister when a vacuum is applied to the canister interior through the vacuum port by the vacuum source.Type: GrantFiled: December 19, 2012Date of Patent: December 30, 2014Assignee: Dornoch Medical Systems, Inc.Inventors: Larry C.

Patent number: 8834432Abstract: An injection site (12) for infusion of parenteral fluids has a pressure-actuated valve (20) and a split septum unit (24), which prevent reflux of blood into the assembly (10). The septum unit (24) includes a resilient split septum body (64) precompressed so that the septum body (64) is caused to protrude proximally (78) upon insertion of a cannula (16). Consequently, upon removal of the cannula (16), there is essentially no “drumming” or creation of friction-induced negative pressures sufficient to generate blood reflux. The preloaded septum body (64) also has its proximal surface (74) essentially flush and coplanar with the adjacent proximal end (66b) of the tubular septum holder (66) to enhance the cleanliness of the unit (24).Type: GrantFiled: July 2, 2012Date of Patent: September 16, 2014Assignee: Nexus Medical, LLCInventors: Chris Winsor, Larry C.
