Appl. No.:

09/434974

Inventors:

Michael W. Kleeman - Sudbury MA
David R. Brengle - San Diego CA
Marc S. Lieberman - Poway CA

Assignee:

Tandem Medical - San Diego CA

International Classification:

A61M 3700

US Classification:

604131, 604151, 417229, 222100, 222101, 222401

Abstract:

The present invention comprises a medication delivery pump that is configured to administer an infusion therapy using a medication delivery container. Medications in a flexible bag are expelled from the bag and delivered to an infusion site. A fluid delivery pump of the invention may have a constant force spring and a mechanical timer. The constant force spring is configured to compress a flexible fluid container. The mechanical timer assembly is coupled to the constant force spring and limits the maximum rate at which the spring compresses the fluid container. The pump may include first and second doors for charging the spring. Opening the first pump door partially charges the constant force spring and opening the second pump door fully charges the constant force spring. The pump provides improved administration of infusion therapy which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

International Classification:

A61M 3700

US Classification:

604131, 604191

Abstract:

The present invention comprises a medication delivery system for administering an infusion therapy using a medication delivery pump and related fluid container. Medications in a flexible bag of the container are expelled from the bag by the pump into an administration set and delivered to an infusion site. The administration set limits the rate at which a spring compresses the bag. The system provides improved infusion therapy administration which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

International Classification:

A61M031/00

US Classification:

604/500000, 604/151000

Abstract:

The present invention relates to delivery containers designed to deliver fluids for infusion to patients in a predetermined sequence, and methods for their construction and use. The containers described herein integrally comprise a plurality of non-fluidly connected chambers. The containers may be configured to deliver a volume of each medication of an infusion therapy in a predetermined sequence, duration, and/or interval from these chambers; alternatively, a container may be part of a larger device that provides the necessary hardware to perform such predetermined delivery. The container provides improved infusion therapy administration by reducing opportunities for error, infection, adverse drug interactions, or other complications.

International Classification:

A61M 500

US Classification:

604191

Abstract:

In accordance with the present invention, there is provided a medication delivery container that is preconfigured to administer an infusion therapy upon activation by a pump mechanism. The configuration of the bag can determine the sequence and amount of medication to be delivered. In one embodiment of the invention, the medication delivery container includes a multi-chamber bag, a manifold assembly and an administration set. The manifold assembly is configured with internal conduits and valves to direct output from each chamber of the bag to an output port in the manifold, and into the administration set. In additional embodiments, there are provided structures in the container to alleviate pressure drop during the application of pressure to the container. Invention containers provide improved infusion therapy administration which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

Abstract:

A physical therapy management system including a motion sensor mounted to a user's leg brace to sense and wirelessly transmit movement of the leg when the user is performing a prescribed exercise therapy routine. An app on the user's computing device receives the sensor motion data and compares the patient's exercise performance to the patient's therapy prescription. Real-time animation of the user's performance is shown on the user's computing device along with exercise guidance. The user may view general and custom videos of exercise routines on the user's computing device. A health care practitioner stores the user's prescription, a list of pre-recorded video therapy exercise files, custom exercise files and the order in which the exercises are to performed under the prescription.
