Embedded ubiquitous services on hospital

  1. 1. Embedded Ubiquitous Services on Hospital Information Systems Presented by Sachin L. Kshirsagar WCE sangli
  2. 2. Contents Introduction Ubiquitous Echograph Networked digital camera ID mapping behaviour of proposed system Prototype of Networked digital camera Commercialized Networked digital camera Conclusion References
  3. 3. Ubiquitous Computing Coined by weiser “ubiquitous computing” as “access anytime anywhere” enhancing computer use by making many computers available throughout the physical environment, but making them effectively invisible to the user
  4. 4. Introduction Paper discuss about two embedded systems Ubiquitous Echograph Networked digital camera Hospital Information System Computational servers processing EMRs Innumerable terminals Information networks Medical device embedded into hospital which is a gigantic computer system
  5. 5. Ubiquitous Echograph Echograph Sensing unit Computation unit Display unit embed the medical device by simply replacing the bus with the information network supporting the HIS
  6. 6. Continued..
  7. 7. Continue.. Working Mobile probe obtain echo signal ,send it via wi-fi Server software reconstruct echogram and send to display Advantages Increases mobility of doctor No need to move patients Decreases maintenance cost
  8. 8. Prototype of Ubiquitous Echograh
  9. 9. Two types of sensors Mechanical scan 1-D echo probe Compress resampled echo signal by LZ-77 compression Generate B-mode images SonoSite SonoHeart Echograph
  10. 10. Networked digital camera Digital camera Charge-coupled device(CCD) Storage(PACS) Display system can be embedded by replacing bus with LAN of HIS
  11. 11. Working Photos taken by camera Stored in temporal server After QA process confirmed photos stored in PACS To smoothen the process HIS use barcode to identify the patient
  12. 12. The system works as a state machine
  13. 13. Prototype of networked digital camera
  14. 14. Continued.. Clinician set camera to barcode reading mode Take barcode of clinician and patient Check in QA interface Confirmed photos are sent to PACS
  15. 15. Commercial networked digital camera
  16. 16. Continued.. System utilizes Eye-Fi to connect to network checks all incoming images and recognize patient id by barcode Following images stored to patients temporal folder Finally confirmed images are stored
  17. 17. Conclusion proposed to embed medical device, a small computer system, into HIS, a gigantic computer system.
