## Abstract

Disclosed herein are different disposable assemblies for the same reusable assembly. The different disposable assemblies include a first disposable assembly and a second disposable assembly. The first disposable assembly may be configured to be operatively coupled to the reusable assembly to deliver fluid, and the second disposable assembly may be configured to be operatively coupled to the reusable assembly to deliver fluid when the first disposable assembly is not operatively coupled to the reusable assembly. The first disposable assembly may have a first set of one or more characteristics, and the second disposable assembly may have a second set of one or more characteristics that is different from the first set of one or more characteristics.

## Claims

### Claim 1

A plurality of disposable assemblies comprising:
a first disposable assembly configured to be operatively coupled to a reusable assembly to deliver fluid, the first disposable assembly having a first plunger pusher and a first set of one or more characteristics; and
a second disposable assembly configured to be operatively coupled to the reusable assembly to deliver fluid when the first disposable assembly is not operatively coupled to the reusable assembly, the second disposable assembly having a second plunger pusher and a second set of one or more characteristics that is different from the first set of one or more characteristics.

### Claim 2 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first disposable assembly is configured to dispense a first amount of fluid with each rotation of a motor rotor included in the first disposable assembly, and wherein the second disposable assembly is configured to dispense a second amount of fluid with each rotation of a motor rotor included in the second disposable assembly.

### Claim 3 (depends on 2)

The plurality of disposable assemblies of claim 2, wherein the first amount is the same as the second amount.

### Claim 4 (depends on 2)

The plurality of disposable assemblies of claim 2, wherein the first amount is different from the second amount, wherein the first disposable assembly is configured to communicate the first amount to the reusable assembly when the first disposable assembly and the reusable assembly are coupled, and wherein the second disposable assembly is configured to communicate the second amount to the reusable assembly when the second disposable assembly and the reusable assembly are coupled.

### Claim 5 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first set of one or more characteristics comprises a fluid reservoir having a first volume, and wherein the second set of one or more characteristics comprises a fluid reservoir having a second volume that is different from the first volume.

### Claim 6 (depends on 5)

The plurality of disposable assemblies of claim 5, wherein the first volume and the second volume have different lengths but the same cross-sectional area.

### Claim 7 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first set of one or more characteristics comprises a cannula having a first length, and wherein the second set of one or more characteristics comprises a cannula having a second length that is different from the first length.

### Claim 8 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first set of one or more characteristics comprises an adhesive material having a first adhesive strength, and wherein the second set of one or more characteristics comprises an adhesive material having a second adhesive strength that is different from the first adhesive strength.

### Claim 9 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first set of one or more characteristics comprises a connection interface for an infusion set tube, and wherein the second set of one or more characteristics does not comprise a connection interface for an infusion set tube.

### Claim 10 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first set of one or more characteristics comprises a first connection interface for an infusion set tube, wherein the second set of one or more characteristics comprises a second connection interface for an infusion set tube, wherein the first interface is different from the second interface.

### Claim 11 (depends on 1)

The plurality of disposable assemblies of claim 1, wherein the first disposable assembly comprises a first gear train coupled to the first plunger pusher, and wherein the second disposable assembly comprises a second gear train coupled to the second plunger pusher.

### Claim 12

An infusion pump system comprising:
a disposable assembly selected from a plurality of disposable assemblies, the plurality of disposable assemblies including a first disposable assembly and a second disposable assembly, the first disposable assembly having a first set of one or more characteristics, and the second disposable assembly having a second set of one or more characteristics that is different from the first set of one or more characteristics, wherein each of the plurality of disposable assemblies comprises a plunger pusher disposed within the housing; and
a reusable assembly configured to deliver fluid when operatively coupled to any disposable assembly of the plurality of disposable assemblies.

### Claim 13 (depends on 12)

The system of claim 12, wherein the first disposable assembly is configured to dispense a first amount of fluid with each rotation of a motor rotor included in the first disposable assembly, and wherein the second disposable assembly is configured to dispense a second amount of fluid with each rotation of a motor rotor included in the second disposable assembly.

### Claim 14 (depends on 13)

The system of claim 13, wherein the first amount is the same as the second amount.

### Claim 15 (depends on 13)

The system of claim 13, wherein the first amount is different from the second amount, wherein the first disposable assembly is configured to communicate the first amount to the reusable assembly when the first disposable assembly and the reusable assembly are coupled, and wherein the second disposable assembly is configured to communicate the second amount to the reusable assembly when the second disposable assembly and the reusable assembly are coupled.

### Claim 16 (depends on 12)

The system of claim 12, wherein the first set of one or more characteristics comprises a fluid reservoir having a first volume, and wherein the second set of one or more characteristics comprises a fluid reservoir having a second volume that is different from the first volume.

### Claim 17 (depends on 16)

The system of claim 16, wherein the first volume and the second volume have different lengths but the same cross-sectional area.

### Claim 18 (depends on 12)

The system of claim 12, wherein the first set of one or more characteristics comprises a cannula having a first length, and wherein the second set of one or more characteristics comprises a cannula having a second length that is different from the first length.
