POST-DOWNLOAD PATIENT DATA PROTECTION IN A MEDICAL DEVICE
First Claim
1. A method comprising:
- storing patient data collected by an external defibrillator during treatment of a patient within a medical device;
allowing users to access the patient data stored in the medical device;
downloading the patient data from the medical device to another device; and
in response to downloading the patient data, protecting the patient data in the medical device such that the protected patient data is inaccessible to at least a first subset of authorized users while the protected patient data in the medical device is accessible to a second subset of authorized users, wherein the patient data was accessible to the first subset of authorized users before the patient data was protected.

Abstract
The disclosure describes techniques for protecting patient data stored in a medical device, such as an external defibrillator. The patient data may be transferred, or downloaded, from the medical device to another device, such as to a computing device for storage or analysis. In response to the download, the medical device may protect the patient data so that at least subset of users can no longer access the patient data. Patient data may be protected by modifying the data form, encrypting the data, moving the data to another memory module, password protecting the patient data, or modifying an access control list associated with the patient data. While the patient data may also be deleted as a technique for protecting the data, not deleting the data may allow the data to be recovered at a later time by an authorized user, i.e., a user not part of the subset.

12. A medical device comprising:
-
a memory that stores patient data, the patient data collected by an external defibrillator during treatment of a patient; a communications circuit configured to communicate with another device; and a processor that allows users to access the patient data stored in the memory, controls the communications circuit to download the patient data to the other device and, in response to the download, protects the patient data in the memory such that the patient data is inaccessible to at least a subset of the users, wherein, to protect the patient data, the processor makes the data inaccessible to a first subset of authorized users while leaving the patient data accessible to a second subset of authorized users, wherein the patient data was accessible to the first subset of authorized users before the patient data was protected. - View Dependent Claims (13, 14, 15, 17, 18, 19, 20, 21, 22)

16. A medical device comprising:
-
a memory that stores patient data collected by an external defibrillator during treatment of a patient; a communications circuit configured to communicate with another device; and a processor that allows users to access the patient data stored in the memory, controls the communications circuit to download the patient data to the other device and, in response to the download, deletes the patient data from the memory.

23. A computer readable medium comprising instructions that cause a processor to:
-
store patient data collected by an external defibrillator during treatment of a patient within a medical device; allow users to access the patient data stored in the medical device; download the patient data to another device; and in response to the download, protect the patient data in the first device such that the protected patient data is inaccessible to at least a first subset of authorized users while the protected patient data is accessible to a second subset of authorized users, wherein the patient data was accessible to the first subset of authorized users before the patient data was protected. - View Dependent Claims (24, 25)
