  • the present invention pertains to transferring files, and, in particular, to a system and method for transferring sleep study files.
  • OSA Obstructive sleep apnea
  • OSA is a condition that affects millions of people from around the world.
  • OSA is characterized by disturbances or cessation in breathing during sleep.
  • OSA episodes result from partial or complete blockage of airflow during sleep that lasts at least 10 seconds and often as long as 1 to 2 minutes.
  • people with moderate to severe apnea may experience complete or partial breathing disruptions as high as 200-500 per night. Because their sleep is constantly disrupted, they are deprived of the restorative sleep necessary for efficient functioning of body and mind.
  • This sleep disorder has also been linked with hypertension, depression, stroke, cardiac arrhythmias, myocardial infarction and other cardiovascular disorders. OSA also causes excessive tiredness.
  • a PSG generally involves a sleep study of a patient where audio and other parameters of the patient is recorded while the patient sleeps.
  • a technician then “scores” the recorded data. Scoring the recorded data involves analyzing the data to identify events that occurred during the PSG that may be useful in diagnosing sleep pathologies.
  • Data collected during a PSG is generally stored in several different files such as multiple audio files, other data files, and a scoring file.
  • the PSG data (also referred to as sleep study data) is generated or used in several different locations, such as a sleep lab, a scoring technician's office, and a physician's office. It is preferable to store the sleep study data at a central location, such as a server, where it is accessible to multiple locations through a network, such as the internet.
  • the server When a file is being uploaded, the server will provide synchronization locking which prevents the same file from being uploaded or downloaded by a different user at the same time.
  • uploads are transferred to a permanent directory and synchronization locking is provided on a file-by-file basis. That is, when uploading of one file is complete, the file will be transferred to the permanent directory and the synchronization locking will stop.
  • file transfers may consist of multiple data files that are related to each other, and as such, must be transferred as one logical unit.
  • an upload if the first one of the files is uploaded to the server properly and the connection is lost while uploading the second one of the data files, then the set of sleep study data files stored on the server will be incomplete.
  • connection is lost while uploading an updated set of sleep study files, the resultant set of sleep study data files on the server will have some data files that are updated and some that are not updated, thus compromising the integrity of the set of sleep study data files stored on the server.
  • the synchronization locking for the first data file will have stopped and another user will be able to download the first data file.
  • the same issues apply when downloading sleep study files. That is, if the connection to the server is lost when downloading files from the server to the client, then the set of sleep study data files stored on the client will be incomplete. Furthermore, if the connection is lost while downloading an updated set of sleep study files, the resultant set of sleep study data files on the client will have some data files that are updated and some that are not updated, thus compromising the integrity of the set of sleep study data files stored on the client. Similarly, if a user is downloading the first data file, the synchronization locking on the server will not prevent users from updating the other sleep data files on the server while the first is being downloaded. The resultant set of sleep data files downloaded to the client will have some data files that are updated and some that are not updated.
  • the sleep study data files For the purpose of transferring the sleep study data files to the server, it is preferable to treat the sleep study data files as a single entity to ensure that the complete set of sleep study data files is uploaded to the server before it is transferred to the permanent directory and that the complete set of sleep study data files is synchronization locked when a user is uploading the sleep study data files.
  • sleep study data files can be packaged into a single file, such as a ZIP file, and then transferred, the process of packaging and unpacking the sleep study data files can become cumbersome and time consuming.
  • method of transferring files includes receiving a download request for a group of files, determining whether the group of files is locked, upon determining that the group of files is not locked, allowing the download request, creating a transfer object corresponding to the group of files and the download request, the transfer object including information on the group of files and the download request, performing download operations on the files in the group of files, and when all files in the group of files have been downloaded, deleting the transfer object.
  • a method of transferring files includes receiving an upload request for a group of files, determining whether the group of files is locked, upon determining that the group of files is not locked, allowing the upload request, creating a transfer object corresponding to the group of files and the upload request, the transfer object including information on the group of files and the upload request, performing upload operations on the files in the group of files, and when all files in the group of files have been uploaded, deleting the transfer object.
