Abstract

A cartridge engageable with a medical device, the method of making a cartridge comprising an ordered arrangement of N electrical components each with different respective values of an electrical property, and an ordered arrangement of N conductors operably coupled to the ordered arrangement of the N electrical components.
A medical device is arranged to receive a cartridge comprises for each of N conductors on the cartridge, at least a first respective contact arranged to electrically couple with the corresponding conductor when the cartridge is engaged with the medical device; the medical device also comprises an evaluation means operable to evaluate the different respective values of an electrical property of N electrical components on the cartridge, wherein the N electrical components form an ordered arrangement which is operably coupled to the N conductors on the cartridge, and a switching arrangement operable to selectively electrically couple a respective pair of contacts to said evaluation means.

First claim

The invention claimed is:

1. A method of preparing a series of uniquely coded cartridge variants engageable with a medical device, wherein, for any of said uniquely coded cartridge variants, performing the steps of:
providing a cartridge;
selecting a unique code, responsive to intended contents of the cartridge;
selecting a value of an electrical property within a respective one of N non-overlapping sets of value ranges of the electrical property, wherein the N non-overlapping value ranges are common to the series of uniquely coded cartridge variants;
designating a respective one of the N non-overlapping value ranges to each of N conductors;
associating with the cartridge an ordered arrangement of N electrical components, each of the N electrical components having a first electrical contact and a second electrical contact, the arrangement of the N electrical components operably coupled to an arrangement of the N conductors so that the first electrical contact of each respective N electrical component connects to a respective one of the N conductors, and wherein each of N electrical component embodies a respectively corresponding one of the selected values of the electrical property; and
selecting a particular order of the N electrical components with respect to the ordered arrangement of N conductors,
wherein the selected values of electrical properties together with the selected order with respect to the N conductors of the N electrical components embodying these values signify in combination the selected unique code.

2. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , wherein within the ordered arrangement of N electrical components, the order of the N electrical components is arranged with respect to the ordered arrangement of N conductors to encode information.

3. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , wherein the electrical property is impedance.

4. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , wherein all of the N electrical components are one selected from the list consisting of:
i. resistors;
ii. capacitors;
iii. inductors; and
iv. diodes.

5. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , wherein the cartridge further comprises a conductor separate to the ordered arrangement of N conductors and not electrically coupled to the ordered arrangement of N electrical components on the cartridge.

6. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , wherein the conductors and the ordered arrangement of N electrical components are mounted on an outer surface of the cartridge.

7. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 ,
wherein the conductors and the ordered arrangement of N electrical components are mounted on a label;
the label is affixed to an outer surface of the cartridge; and
the label extends around the cartridge and overlaps itself to cover the ordered arrangement of N electrical components.

8. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , further comprising a non-conductive protective layer applied over at least the N conductors.

9. The method of preparing a series of uniquely coded cartridge variants engageable with a medical device according to claim 1 , wherein the series of uniquely coded cartridge variants exclusively comprises coded cartridge variants wherein the N electrical components have values of the electrical property selected from respective ones of said N non-overlapping value ranges of the electrical property.
