Appl. No.:

09/561047

Inventors:

David J. McNally - Salt Lake City UT
Al Halbert - Bluffdale UT

Assignee:

Zevex, Inc. - Salt Lake City UT

International Classification:

A61M 500

US Classification:

604250, 604246, 604251, 248 681, 211 601, 211 8701

Abstract:

A pinch clip occluder system for infusion sets includes a housing and a clamp movably disposed within the housing to selectively occlude an infusion set. The pinch clip nests in an adapter placed on an enteral feeding pump such that when the pinch clip occluder is properly position, flow is allowed through the infusion set, but when the pinch clip occluder is not properly positioned in the adapter, flow through the infusion set is prevented.

Appl. No.:

10/016669

Inventors:

David J. McNally - Sandy UT, US
Alejandro Flores - West Newton MA, US

Assignee:

Zevex, Inc. - Salt Lake City UT

International Classification:

A61M001/00

US Classification:

604 32, 60410303, 604332

Abstract:

An enterostomy device for providing fluids and nutrients through a stoma formed through the abdominal wall of a patient is described. The enterostomy device, which may be configured as either a gastrostomy device or a jejunostomy device, comprises a low-profile retaining member which is configured to be unobtrusively positioned within the stomach or the intestine, and which is configured to provide sufficient surface area for contacting the stomach or intestine to prevent unintentional removal or release of the enterostomy device from the patient. The enterostomy device is also structured with a low-profile port hub for facilitating the inflation of the retaining member and feeding and venting through the stoma.

Assignee:

Zevex, Inc. - Salt Lake City UT

International Classification:

A61M 5/00

US Classification:

604246, 604247, 604256, 604 30

Abstract:

An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. When a pair of occluders are used in sequence, an in-line pump may be formed.

US Classification:

604246, 604247, 604256

Abstract:

An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. The occluder may also be configured to allow flow when the infusion set adjacent the occluder is moved sideways relative to the occluder or maintained at an angle relative to the occluder. When a pair of occluders are used in sequence, an in-line pump may be formed.
