Abstract

A head-mounted display device for interface with a blood processing machine using a disposable component having tubing and a blood component receptacle includes a frame configured to be mounted on a person's head and configured to hold a lens in front of an eye of the person. The display device includes a display, a wireless transceiver configured to communicate with a network, and a processing circuit. The processing circuit is coupled to the frame, the display and the wireless transceiver and receives instructions for training the person how to use the blood processing machine. The processing circuit overlays indicators, text, highlighting and/or icons on the blood processing machine as seen from a field of view of the person based on the instructions to train the person in using the blood processing machine.

First claim

What is claimed is:

1. A head-mounted display device for interface with a blood processing machine using a disposable component having tubing and a blood component receptacle, the display device comprising:
a frame configured to be mounted on a person's head and configured to hold a lens in front of an eye of the person;
a display;
a wireless circuit configured to communicate with a network;
a camera; and
a processing circuit coupled to the frame, the display, the wireless transceiver and the camera, the processing circuit further configured to retrieve via the wireless circuit instructions for training the person how to use the blood processing machine and to overlay indicators, text, highlighting and/or icons on the blood processing machine as seen from a field of view of the wearer based on the instructions to train the person in using the blood processing machine.

2. The head-mounted display device of claim 1 , wherein the instructions comprise step-by-step instructions and the indicators, text, highlighting and/or icons overlayed on the blood processing machine as seen from a field of view of the wearer are based on the step-by-step instructions, wherein the instructions comprise at least three step-by-step instructions.

3. The head-mounted display device of claim 1 , wherein the training instructions are presented on the display and are further related to a screen being displayed on the blood processing device approximately simultaneously.

4. The head-mounted display device of claim 1 , wherein the processing circuit is configured to provide an augmented reality display as seen from a field of view of the wearer.

5. The head-mounted display device of claim 1 , wherein text is overlayed on the blood processing machine as seen from the field of view of the wearer, wherein the text instructs the wearer to open a door and/or remove a line of the blood processing machine and/or the disposable component.

6. The head-mounted display device of claim 1 , wherein the processing circuit is configured to direct the wearer to align the field of view using arrows or audible instructions.

7. The head-mounted display device of claim 1 , wherein the processing circuit is configured to overlay an indicator to show the wearer a button to push on the blood processing machine.

8. The head-mounted display device of claim 1 , wherein the display is configured to cover substantially all of the lens held in front of the eye of the wearer.

9. The head-mounted display device of claim 1 , wherein the processing circuit is configured with a virtual reality engine configured to provide video to the display.

10. The head-mounted display device of claim 1 , wherein the processing circuit is configured to acquire an image of the blood processing machine using the camera and to detect a condition of the blood processing machine from the acquired image, the processing circuit further configured to transmit a request for the instructions for training the person to use the blood processing machine based on the indicated condition.

11. The head-mounted display of claim 1 , wherein the instruction comprises a video, wherein the instruction video is configured to train a patient about a procedure to be implemented using the medical device.

12. A head-mounted display device for interface with a blood processing machine using a disposable component having tubing and a blood component receptacle, the display device comprising:
a frame configured to be mounted on a person's head and configured to hold a lens in front of an eye of a person;
a display;
a wireless circuit configured to communicate with a network;
a camera; and
a processing circuit coupled to the frame, the display, the wireless transceiver and the camera, the processing circuit configured to store instructions for using the blood processing machine and to use the display to provide an augmented reality display of the blood processing machine on the lens based on the instructions to assist the person in using the blood processing machine.

13. The head-mounted display device of claim 12 , wherein the instructions comprise step-by-step instructions and the augmented reality display of the blood processing machine on the lens is based on the step-by-step instructions.

14. The head-mounted display device of claim 12 , wherein text is overlayed on the blood processing machine as seen from a field of view of the wearer, wherein the text instructs the person to open a door and/or remove a line of the blood processing machine and/or the disposable component.

15. The head-mounted display device of claim 12 , wherein the processing circuit is further configured to use the display to display a service manual and/or trouble-shooting guide for the blood processing machine.

16. The head-mounted display device of claim 12 , wherein the processing circuit comprises a video processing circuit configured to detect that a clamp on the blood processing machine is closed when it needs to be opened, wherein the processing circuit is configured to retrieve from a memory a picture or video of the disposable component properly installed and zoom in on the clamp that needs to be opened.

17. A method of using a head-mounted display device to train a wearer to use a blood processing machine configured for use with a disposable component having tubing and a blood component receptacle, the method comprising:
transmitting a request from the head-mounted display device over a wireless network for instructions for training the wearer to use the blood processing machine;
receiving over the wireless network instructions for training the wearer to use the blood processing machine;
overlaying indicators, text, highlighting and/or icons on the blood processing machine as seen from a field of view of the wearer of the head-mounted display device based on the instructions, whereby the wearer is trained to use the blood processing machine.

18. The method of claim 17 , wherein the instructions for training the wearer to use the blood processing machine comprise an introduction to features of the blood processing machine.

19. The method of claim 18 , wherein the instructions for training the wearer to use the blood processing machine further comprise information about new features downloaded to the device by way of a software update.

20. The method of claim 17 , further comprising:
acquiring an image of the blood processing machine using a camera of the head-mounted display device;
detecting a condition of the blood processing machine from the acquired image; and
generating the request for instructions based on the detected condition.
