## Abstract

A medical device for caring for a patient includes a patient utility for measuring a patient parameter or administering a therapy to the patient and an alarm system that has a receiver to accept status information about the medical device. A use detector of the alarm system is structured to determine when the medical device is being prepared for use and a status detector of the alarm system is adapted to determine from the status information that the medical device is in a ready state. The alarm system further includes an alarm that is activated when the medical device is both being prepared for use and not in the ready state. This description also includes methods of generating an alarm when the medical device is both being prepared for use and not in the ready state.

## Claims

### Claim 1

A medical device, comprising:
a patient utility configured to one or both of monitor a patient parameter and administer a patient therapy;
a status detector configured to determine a readiness state of the medical device, the readiness state determined by one or both of:
detecting a component readiness state of at least one component of the medical device, and
detecting one or both of a device maintenance status of the medical device and a component maintenance status of at least one component of the medical device;
a use detector configured to determine a change in a use status of the medical device, the use status based on sensing a transition of the medical device from a not-in-use condition; and
an indicator configured to be activated based on the readiness state of the medical device and the change in the use status of the medical device.

### Claim 2 (depends on 1)

The medical device of claim 1, wherein the at least one component of the medical device is a consumable component and the status detector includes a consumable aging component configured to determine an age of the consumable component relative to an expiration date associated with the consumable component, the status detector causing the readiness state of the medical device to indicate a not ready state in response to the age of the consumable component exceeding the expiration date.

### Claim 3 (depends on 1)

The medical device of claim 1, wherein the status detector includes a maintenance schedule component configured to:
determine if one or both of the medical device and the at least one component of the medical device exceeds a service date respectively associated with the medical device and the at least one component of the medical device,
wherein the status detector is further configured to cause the readiness state of the medical device to be a not ready state in response to one or both of the medical device or the at least one component of the medical device exceeding a service date.

### Claim 4 (depends on 3)

The medical device of claim 3, wherein the service date is associated with a software update of the medical device.

### Claim 5 (depends on 1)

The medical device of claim 1, wherein the status detector is configured to:
receive the component readiness status of the at least one component of the medical device, and
determine the component readiness status of the at least one component of the medical device to be at least one of greater than a threshold value, less than a threshold value, and outside of threshold range.

### Claim 6 (depends on 5)

The medical device of claim 5, wherein the status detector is further configured to cause the readiness state of the medical device to be a not ready state in response to the component readiness status being at least one of greater than a threshold value, less than a threshold value, and outside of a threshold range.

### Claim 7 (depends on 1)

The medical device of claim 1, further comprising a user interface configured to accept user input to configure at least one of the status detector or the indicator.

### Claim 8 (depends on 1)

The medical device of claim 1, wherein the use detector includes a motion detector component configured to:
generate a motion signal in response to the transition of the medical device from a not-in-use condition, and
cause the change in the use status of the medical device.

### Claim 9 (depends on 1)

The medical device of claim 1, wherein the use detector includes a power detector component configured to:
generate a remove signal in response to the medical device separating from an external power source, and
cause the change in the use status of the medical device.

### Claim 10 (depends on 1)

The medical device of claim 1, wherein the not-in-use condition includes one or both of an ideal condition and an at rest condition.

### Claim 11 (depends on 1)

The medical device of claim 1, wherein the indicator includes an alarm.

### Claim 12 (depends on 1)

The medical device of claim 1, wherein the indicator includes an output that one or both of the medical device and a component of the medical device requires service.

### Claim 13

A medical device, comprising:
a status detector configured to determine a ready state or a non-ready state of the medical device based on:
one or more of a component readiness status of at least a component of the medical device, and
a maintenance status of at least one of the medical device or the at least a component of the medical device,
a use detector configured to detect a change in a use status of the medical device based on determining a transition of the medical device from a not-in-use condition; and
an indicator that is activated based on the status detector determining the medical device is in the non-ready state and the use detector detecting the change in the use status of the medical device.

### Claim 14 (depends on 13)

The medical device of claim 13, wherein the at least a component is a consumable component having an expiration date and the status detector includes a consumables aging component, the non-ready state determined based on a current date being later than the expiration date of the consumable.

### Claim 15 (depends on 13)

The medical device of claim 13, wherein the at least a component is a consumable component having a usable age and a current age associated therewith, and the status detector includes a consumables aging component, the non-ready state determined based on the status detector determining that the current age is greater than the usable age.

### Claim 16 (depends on 13)

The medical device of claim 13, wherein the status detector includes a maintenance schedule component, the non-ready state determined based on the at least a component of the medical device or the medical device being beyond a service date associated therewith.

### Claim 17 (depends on 16)

The medical device of claim 16, wherein the service date is associated with a software update.

### Claim 18 (depends on 13)

The medical device of claim 13, wherein the change in the use status is not based on a user supplied input to the medical device.

### Claim 19 (depends on 13)

The medical device of claim 13, wherein the change in the use status is based on a change in one of a physical location, physical arrangement, or a physical orientation of the medical device.

### Claim 20 (depends on 13)

The medical device of claim 13, wherein the not-in-use condition includes an idle condition or an at rest condition of the medical device.
