Abstract

A remotely programmable infusion system for administering liquid to a patient includes an infusion pump unit having a pump for infusing liquids operated by means of a control including a programmed processing unit and a memory chip. The processing unit operates in accordance with delivery program data stored in the memory circuit for executing an infusion delivery sequence. An output circuit is operatively disposed between the processing unit and the pump unit to control operation of the pump unit in accordance with the infusion delivery sequence. A wireless data communication circuit is operatively connected to the control for transmitting and receiving data. A programmer remote from the pump unit includes a programmed processing unit, a memory circuit, a user interface operatively associated with the processing unit for entering program commands and configuring delivery program data for storage in the memory circuit and a modem circuit operatively connected to the processing unit for transmitting and receiving data to and from the infusion pump unit. A remote communication interface unit includes a pump interface operatively communicating, in use, with the pump wireless data communication circuit, a programmer interface, including a modem circuit operatively communicating, in use, via a telephone line with the programmer modem circuit and a control circuit operatively connected to the pump interface and the programmer interface for channeling data between the pump interface and the modem circuit.

Claims

1. A remotely programmable infusion system for administering liquid to a patient, comprising:

an infusion pump including pumping means for infusing liquids to a patient, a control including a programmed processing unit and a memory circuit, the processing unit operating in accordance with delivery program data stored in the memory circuit for executing an infusion delivery sequence, an output circuit operatively disposed between said processing unit and said pumping means to control operation of said pumping means in accordance with the infusion delivery sequence, and an infrared communication circuit operatively connected to said control for transmitting and receiving data in an infrared format;

a programmer remote from the pump including a programmed processing unit, a memory circuit, a user interface operatively associated with said processing unit for entering program commands and configuring delivery program data for storage in the memory circuit, and a modem circuit operatively connected to said processing unit for transmitting and receiving data in a modem format; and

a communication interface unit including an infrared communication circuit operatively communicating, in use, with said pump infrared communication circuit, a modem circuit operatively communicating, in use, via a telephone line with the programmer modem circuit and a control circuit operatively connected to said modem circuit and said infrared communication circuit for channeling between the modem circuit and the infrared communication circuit.

2. The remotely programmable infusion system of claim 1 wherein said programmer further includes an infrared communication circuit whereby said programmer can directly transfer data to said pump infrared communication circuit.

3. The remotely programmable infusion system of claim 1 wherein said control circuit channels data received from the infrared communication circuit to the modem circuit and channels data received from the modem circuit to the infrared communication circuit.

4. A remotely programmable infusion system for administering liquid to a patient, comprising:

an infusion pump including pumping means for infusing liquids to a patient, a control including a programmed processing unit and a memory circuit, the processing unit operating in accordance with delivery program data stored in the memory circuit for executing an infusion delivery sequence, an output circuit operatively disposed between said processing unit and said pumping means to control operation of said pumping means in accordance with the infusion delivery sequence, and a wireless data communication circuit operatively connected to said control for transmitting and receiving data;

a programmer remote from the pump including a programmed processing unit, a memory circuit, a user interface operatively associated with said processing unit for entering program commands and configuring delivery program data for storage in the memory circuit, and a modem circuit operatively connected to said processing unit for transmitting and receiving data to and from the pump; and

a remote communication interface unit including a pump interface operatively communicating, in use, with said pump wireless data communication circuit, a programmer interface including a modem circuit operatively communicating, in use, via a telephone line with the programmer modem circuit, and a control circuit operatively connected to said pump interface and said programmer interface for channeling data between the pump interface and the modem circuit.

5. The remotely programmable infusion system of claim 4 wherein said programmer further includes a wireless communication circuit whereby said programmer can directly transfer data to said pump through-the-air data communication circuit.
