International Classification:

A61M 5/168

US Classification:

604151

Abstract:

The present invention provides an infusion pump control system comprises a plurality of computing components positioned on discrete hardware modules to complete an infusion task. Those discrete processors, which are internally redundant and communicate through a common medium that provides for redundancy of the communication ability to react to internal failures in a known manner, implement capabilities specific to infusion pump functions, to complete an infusion task. Also, this invention provides automatically switchable redundant power supplies and a new mechanism for firmware provisioning using multi-dropped JTAG for a plurality of computing components.

Abstract:

An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.

International Classification:

A61M 5/145
A61M 5/145

Abstract:

An infusion apparatus for use with a syringe includes a housing enclosing a drivetrain. The drivetrain includes a pinion, spur gears, and a worm gear. One spur gear is arranged to engage with the pinion and another spur gear is arranged to engage with the worm gear. The housing also includes a carriage movable with respect to the housing. A frame on the carriage receives a syringe plunger. A rack on the carriage engages with the pinion to move the carriage parallel to a longitudinal axis of the housing. A pusher assembly of the housing securely engages with the syringe plunger. A motor in the apparatus rotates a worm drive that meshes with the worm gear to drive the drivetrain. A trigger of the apparatus is configured to disengage the worm drive from the worm gear to allow free movement of the carriage relative to the housing.
