Abstract

A collection and reporting system for infusion appliance comprising a battery operated monitoring device connected to the power source of the infusion appliance which monitors its usage for a certain period of time, whereupon the data pertaining to the various assignments are transferred to collecting means and further listed by printing means. The data include information pertaining to the monitoring device itself, the infusion appliance being monitored, the patient data and the usage data indicative of the functioning status of the infusion appliance. Usage data are logged every six minutes. The data residing in monitoring device or the meter are collected, recorded, printed and then cleared every one hundred eighty-four days or whenever the storing capacity of the RAM of the meter is exceeded. An indicator is turned on at the six month point to signal the need for collecting data.

Claims

1. In combination with an electric consuming medical appliance device or patient monitoring device, a usage monitoring device for acquiring usage data solely from input electrical means to said electrical device, said usage monitoring device comprising:

logging means for acquiring usage data from said input electrical means wherein said usage data are representative of at least two states indicative respectively of the functioning or the nonfunctioning of said input electrical means;

storing means mounted within said logging means for accumulating said usage data during a first mode of operation; and

means for retrieving said data from said storing means during a second mode of operation.

2. The combination of claim 1, wherein said logging means comprise:

means for generating a first periodic a signal; and

means responsive to said signal for setting said first mode of operation for loading said data at regular first periodic intervals.

3. The combination of claim 2, wherein said means for setting said first mode of operation comprises:

a first input port connected to said means for generating; and

means for initiating said logging means upon detection of said first periodic signal signal on said first port.

4. The combination of claim 1, which further comprises a programmable data microprocessor including said logging means, said means for setting and said means for triggering, where said microprocessor is directly attached to said medical device.

5. The combination of claim 4, wherein said microprocessor further comprises a separate power supply and means for a third mode of operation allowing replacement of said separate power supply after retrieval of usage data.

6. The combination of claim 5, wherein said means for a third mode of operation is responsive to said means for interpreting.

7. The combination of claim 1, wherein said means for retrieving said usage data comprises:

means for issuing a second periodic signal;

means responsive to said second periodic signal for triggering said second mode of operation for retrieving said stored usage data at regular second time intervals.

8. The combination of claim 1, wherein said means for triggering said second mode comprise;

a second input port connected to said means for issuing; and

means for interpreting said first and second periodic signals on said first and second ports.

9. The combination of claim 7, further comprising separate means for visually indicating that said second time interval has elapsed.

10. The combination of claim 9, which comprises means for energizing said indicating means when said storing means have no remaining capacity, said second time interval having not elapsed yet.

11. The combination of claim 9, wherein said indicating means comprise at least one electromechanical flag indicator.

12. The combination of claim 9, wherein said indicating means comprise at least one thermal flag indicator.

13. The combination of claim 7, wherein said second time intervals are set commensurately with the capacity of said storing means and the rated lifetime of said separate power supply.

14. The combination of claim 13, wherein said logging means comprise at least one programmable read-only memory and said storing means comprise at least one random-access memory.

15. The combination of claim 13, wherein said storing means also include information pertaining to a user of said medical device, and means for entering said information into said storing means before said medical device is assigned to said user.

16. The combination of claim 13, wherein said storing means also include information pertaining to said input electrical means and said logging means, said information being recorded before said input electrical means are put into use.

17. The combination of claim 13, which comprises means for clearing said storing means after said data has been retrieved.

18. The combination of claim 13 which comprises at least one fiber optic cable connecting said logging means to said input electric means.

19. The combination of claim 13 which comprises at least one coaxial cable connecting said logging means to said input electrical means.

20. The combination of claim 13, further comprising means for recording data other than said usage data connected to said retrieving means.

21. The combination of claim 20, wherein said recording means comprise at least one printer.
