Abstract: A system and method for remote monitoring and/or management of infusion therapies. A user can monitor and manage server-connected pumps at a remote location, such as a computer or PDA. Pumps located at an institution, such as a hospital or patients home, are connected, for example, via the Internet to a server that includes a database of information. A user can operate the pump, from a remote location, by using an interface displayed on the remote site. The operator can manage pump operations by use of the interface. In this context, the user can turn the pump on and off, select infusion rates, dose amounts, etc. all from the convenience of the remote location.

Abstract: A linear peristaltic pump for pumping fluid through a resilient tube has a pair of pumping fingers, a pair of pinching fingers, and a strain gauge to monitor pressure inside the tube. The first pumping finger squeezes the tube at a first location, and the second pumping finger squeezes the tube at a second location. Additionally, the first pumping finger is configured and operated to displace approximately twice the fluid volume displaced by the second pumping finger. The first pinching finger occludes the tube upstream to the first pumping finger and the second pinching finger occludes the tube between the first and second pumping fingers. To monitor dimensional changes in the outer diameter of the tube and thereby indicate pressure inside the tube, the strain gauge is mounted on the pump between the second pinching finger and first pumping fingers. Finally, a leaf spring and photoelectric sensor are associated with the first pumping finger to indicate when the finger is in its fully withdrawn position.

Abstract: A dual controller for an IV infusion system comprises a microprocessor to concurrently control the rate of infusion through two IV units. The control of the rate of infusion is provided by a stepper motor driven regulator which is selectively positionable for compressibly engaging the IV tubing. A flow sensor employs a case of infrared transparent material which mounts to a drip chamber of the infusion unit. The flow sensor provides an output pulse to the microprocessor in response to a drop of fluid in the drip chamber interrupting a light path extending from an array of light emitting diodes and a photo transistor. The light emitting diodes are pulsed between energized and non-energized states so that changes in the ambient light level do not adversely effect the sensed drop rate.

Abstract: Apparatus controls the rate of passage of fluid drops through a drip controller in accordance with a preset rate. When the rate of passage of the fluid drops is less than the preset rate, a stepper motor is incrementally operated at progressive instants of time to open the drip chamber until the measured rate is equal to the preset rate. When the rate of passage of the fluid drops is greater than the preset rate, the stepper motor is operated instantaneously to close the passage through a number of increments corresponding to the difference in the measured and preset rates.An alarm is energized when the stepper motor is positioned to provide for a maximum flow of fluid and the rate is still below the preset rate. An alarm is also energized when the passage is closed and the preset rate indicates a desired flow of fluid.An emergency motor is also provided to control the opening in the passage. Before the operation of the apparatus is instituted, the stepper motor is operated to close the drip chamber.

Abstract: A rate meter senses successive drops of fluid flowing through a conduit and produces gating periods with time durations corresponding to the period of time between such successive drops. The rate meter then determines the number of incremental time periods in each gating period. The rate meter generates the reciprocal of this determination to obtain an indication of the rate of fluid flow. The rate meter may be self-contained. It includes a housing having a vertically disposed channel constructed to retain the conduit and a horizontally disposed channel communicating with the vertically disposed channel. The horizontally disposed channel is constructed to receive a cross bar made from a resilient material and fixedly disposed on the conduit. The cross bar supports the rate meter in a freestanding relationship. The cross bar may be provided with slots near its ends to enhance its resiliency.
