Abstract:
An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.
Abstract:
A system for electronic patient care includes a hub. The hub is configured to monitor a patient-care device. The sandbox may be configured to control access to at least one of a hardware resource and a software resource. The hub is further configured to identify the patient-care device and execute an application to monitor the patient-care device. The hub executes the application within the sandbox component such that the application accesses the at least one of the hardware resource and the software resource through the sandbox component. The hub may be further configured to control the patient-care device. The hub may be further configured to receive an identification from the patient-care device and download the application from a server associated with the identification. The hub may be further configured to receive an identification from the patient-care device and update the application from a server associated with the identification.
Abstract:

The system includes a controller configured to calculate a trajectory for delivering infusible fluid, the trajectory comprising at least one volume of fluid, and determine a schedule for delivering the at least one volume of fluid according to the trajectory, wherein the schedule comprising an interval and a volume of infusible fluid for delivery. The system also includes a volume sensor assembly for determining the at least one volume of fluid delivered, wherein the controller recalculates the trajectory based on the volume of fluid delivered.
Abstract:
A wearable infusion pump assembly. The wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an externa! infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from {lie reservoir and providing the quantity of infusible fluid to the volume sensor assembly- The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system also includes at least one optical sensor assembly, a first valve assembly configured to selectively isolate the pump assembly from the reservoir. The fluid delivery system further includes a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set. The at least one optica! sensor assembly is configured to sense the movement of the pump assembly.
Abstract:
A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user. A dynamic support apparatus for supporting the prosthetic arm apparatus has a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic support apparatus has a control system that is operably connected to the dynamic interface and controls the dynamic interface to change its geometry.
Abstract:
A system and method for controlling a device such that device operates in a smooth manner. The system may switch between control architectures or vary gain coefficients used in a control loop to control the device. As the architecture or gains are switched, the control signal may be smoothed so that the device does not experience an abrupt change in the control signal it receives. In one embodiment, the control signal may be smoothed by adding a decaying offset value to the control signal to create a smoothed control signal that is applied to the device.
Abstract:
A number of racks which are configured to allow a number of devices to couple thereto are provided. In some embodiments, the racks are for use with a number of medical devices. Devices may be coupled to a rack by clamps. The racks may include a number of connectors which provide power and/or a network connection to devices coupled thereto. The racks may include a clamp which allows the racks to couple to a supporting structure such as a pole.
Abstract:
A system includes first and second hubs. The first hub is configured to communicate data with a medical device through a Local Area Network and package the data into at least one application-layer packet. The second hub is configured to receive the at least one application-layer packet from the first hub operatively through at least one cellular network.
Abstract:
A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen. The processor is configured to detect an anomaly in the tubing using the data from a position sensor on the position of the plunger.
