Abstract

A system and method of recording a state of a medical device having a disposable component includes operating the medical device to provide a medical procedure using a disposable component. The disposable component is installed on an external surface of the medical device housing by a human operator and removable therefrom for disposal. The system and method include detecting an error condition on the medical device and, in response, acquiring an image from a camera coupled to the medical device. The image, representing the disposable component and the external housing, is stored in a memory of the medical device and is accessible for later retrieval.

First claim

What is claimed is:

1. A method of recording a state of an apheresis machine having a disposable component disposed thereon, the disposable component comprising tubing and a blood bag, wherein the disposable component is configured to be installed on the apheresis device by a human operator, comprising:
detecting an error condition on the apheresis device;
providing at least one of an audible alert and a visual alert in response to the detected error condition;
acquiring with a camera an image of a forward-facing external surface portion of the apheresis machine and the tubing and the blood bag of the disposable component, wherein the image is acquired automatically without requiring user input;
recording medical device information comprising the image;
generating a message comprising the image; and
transmitting the message comprising the image to a remote computer.

2. The method of claim 1 , wherein the message further comprises an indication of a failure, wherein the message is transmitted to a manufacturer of the component.

3. The method of claim 1 , further comprising providing contact information for the manufacturer to the human operator via a user interface of the apheresis device.

4. The method of claim 1 , wherein the apheresis machine has imaging hardware installed for the camera.

5. The method of claim 1 , wherein the image is acquired automatically in response to the error condition.

6. The method of claim 1 , wherein the medical device information comprises a make, model or type of medical device.

7. A method of recording a state of a medical device having a programmed processing circuit and a disposable component disposed on an external surface of a medical device housing, wherein the disposable component is configured to be installed on the external surface by a human operator and removable therefrom for disposal, comprising:
operating the medical device to provide a medical procedure using the disposable component;
detecting an error condition on the medical device using the processing circuit, wherein the processing circuit, in response to the detection of the error condition, acquires an image from a camera coupled to the medical device, the image representing portions of the disposable component comprising a plurality of lines and at least one blood product bag and ft portions of the external housing of the medical device; and
storing the image in a memory of the medical device, wherein the memory is accessible for later retrieval of the image.

8. The method of claim 7 , wherein the medical procedure is an apheresis procedure.

9. The method of claim 7 , wherein the error condition results in the processing circuit stopping the medical procedure.

10. The method of claim 7 , the processing circuit detecting error conditions of a first type and error conditions of a second type, wherein the processing circuit acquires the image when error conditions of the first type are detected and does not acquire the image when error conditions of the second type are detected.

11. The method of claim 10 , further comprising providing at least one of a visual and audible alarm on a user interface of the medical device in response to the error conditions of the first type and the error conditions of the second type.

12. The method of claim 7 , further comprising transmitting the image stored in the memory over a network to a remote computing device without requiring input from a human operator.

13. The method of claim 7 , further comprising transmitting the image stored in the memory over a network to a remote computing device in response to input from a human operator.

14. The method of claim 7 , further comprising receiving a request for the image over a network at the processing circuit from a remote computer and, in response, transmitting the image over the network to the remote computer.

15. The method of claim 7 , further comprising using the camera and processing circuit to detect improper installation of the disposable component and providing an audible and/or visual alert to a user interface of the medical device in response to detection of improper installation of the disposable component.

16. A medical device, comprising:
a medical device housing having an external surface;
a disposable component disposed on the external surface of the medical device housing, wherein the disposable component is configured to be installed on the external surface by a human operator and removable therefrom for disposal;
a camera coupled to the medical device and configured to acquire an image representing the disposable component and at least a portion of the external surface, the camera coupled to the medical device in a position to image a plurality of lines of the disposable component and at least one blood product bag of the disposable component; and
a programmed processing circuit configured to:
operate the medical device to provide a medical procedure using the disposable component, wherein the medical procedure is an apheresis procedure,
detect an error condition on the medical device,
in response to the detection of the error condition, acquire an image from the camera; and
store the image in a memory of the medical device, wherein the memory is accessible for later retrieval of the image.

17. The medical device of claim 16 , wherein the programmed processing circuit is configured to store a plurality of images, each image acquired in response to a detection of an error condition.

18. The medical device of claim 17 , further comprising a network interface circuit configured to transmit the stored images over a network to a remote computer.

19. The medical device of claim 18 , further comprising a user interface device coupled to the programmed processing circuit, wherein the programmed processing circuit is configured to transmit the stored images in response to a user input provided via the user interface device.
