Abstract

Abstract A programmable infusion system includes a disposable IV tubing apparatus for conveying intravenous fluid from a source to a patient. A compact, portable case has a receptacle for removably receiving a segment of the disposable apparatus. A peristaltic pump is mounted in the case for engaging the segment of the disposable apparatus and pumping intravenous fluid therethrough. A motor is mounted in the case and is connected for driving the pump upon energization thereof. A bar code reader is mounted in an edge portion of the case for sensing a bar code label attached to the source of intravenous fluid, such as a bag. The bar code label represents the prescribed fluid delivery parameters. These are read and displayed in alphanumeric form by the system when the edge portion of the case containing the bar code reader is passed over the label. A micro-controller mounted in the case energizes the motor so that the peristaltic pump conveys the fluid through the disposable apparatus in accordance with the delivery rate parameters.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 209 words
A programmable infusion system, comprising: disposable IV tubing means for conveying intravenous fluid from an IV fluid bag to a patient; a compact, portable case having a receptacle for removably receiving an intermediate pliant segment of the disposable IV tubing means; peristaltic pump means mounted in the case for engaging the intermediate pliant segment of the disposable IV tubing means and pumping intravenous fluid therethrough; motor means mounted in the case for driving the peristaltic pump means upon energization thereof; bar code reader means mounted in an edge portion of the case for sensing a bar code label associated with the IV fluid bag representing a plurality of fluid delivery parameters when the edge portion of the case is passed over the label and for generating bar code signals representative thereof; display means mounted in the case for visualizing information in alphanumeric form; and control means mounted in the case for receiving the bar code signals and causing the display means to display the delivery rate parameters in alphanumeric form for verification by the patient and for energizing the motor means so that the peristaltic pump means will pump the intravenous fluid through the intermediate segment of the disposable IV tubing means in accordance with the delivery rate parameters.
Claim 2
Dependent Claim 209 words
A programmable infusion system, comprising: disposable IV tubing means for conveying intravenous fluid from an IV fluid bag to a patient; a compact, portable case having a receptacle for removably receiving an intermediate pliant segment of the disposable IV tubing means; peristaltic pump means mounted in the case for engaging the intermediate pliant segment of the disposable IV tubing means and pumping intravenous fluid therethrough; motor means mounted in the case for driving the peristaltic pump means upon energization thereof; bar code reader means mounted in an edge portion of the case for sensing a bar code label associated with the IV fluid bag representing a plurality of fluid delivery parameters when the edge portion of the case is passed over the label and for generating bar code signals representative thereof; display means mounted in the case for visualizing information in alphanumeric form; and control means mounted in the case for receiving the bar code signals and causing the display means to display the delivery rate parameters in alphanumeric form for verification by the patient and for energizing the motor means so that the peristaltic pump means will pump the intravenous fluid through the intermediate segment of the disposable IV tubing means in accordance with the delivery rate parameters.
Claim 3
Dependent Claim 28 words
A programmable infusion system according to claim 1 and further comprising keypad means mounted in the case for enabling a user to send commands to the control means.
Claim 4
Dependent Claim 40 words
A programmable infusion system according to claim 1 and further comprising means positioned inside the case adjacent the receptacle for detecting a bubble inside the disposable IV tubing means and for sending a bubble detect signal to the control means.
Claim 5
Dependent Claim 50 words
A programmable infusion system according to claim 1 and further comprising means mounted to a bottom wall of the receptacle for detecting an expansion of the segment of the disposable IV tubing means indicating the existence of an occlusion and for sending an occlusion detect signal to the control means.
Claim 6
Dependent Claim 38 words
A programmable infusion system according to claim 1 and further comprising means for communicating with a remote computer for receiving and conveying to the control means commands for causing the control means to modify the delivery rate parameters.
Claim 7
Dependent Claim 21 words
A programmable infusion system according to claim 1 wherein the delivery rate parameters include volume per unit time and total volume.
Claim 8
Dependent Claim 28 words
A programmable infusion system according to claim 1 wherein the delivery rate parameters include a delivery mode selected from the group consisting of continuous, Bolus, periodic and aperiodic.
Claim 9
Dependent Claim 51 words
A programmable infusion system according to claim 1 and further comprising means mounted in the case for generating an audible warning signal, and further wherein the control means includes means for detecting when the source of intravenous fluid is nearly empty and for activating the audible warning means in response thereto.
