Abstract

A medical device includes a treatment module configured to apply a treatment to a patient. The medical device includes an interface configured to operatively connect to a removable storage device storing authorization data that identifies a level of treatment authorization. The medical device includes a processing device configured to perform operations in response to receiving user input indicating a treatment should be initiated. The operations include determining whether the removable storage device is valid for use with the medical device. If the removable storage device is determined to be valid, the authorization data is accessed. The processing device determines whether the treatment is authorized based on the accessed authorization data. If the treatment is determined to be authorized, the treatment module is controlled to apply the treatment. If the treatment is determined to not be authorized, the treatment module is controlled such that the treatment is not applied.

Claims

1. A medical device configured to communicate with a remote computer system, the medical device comprising:

a treatment source configured to apply a therapy to damaged tissue of a patient to facilitate healing of the damaged tissue; and

one or more processing devices configured to;

receive, via a wireless network or a user input, a treatment regimen that identifies a scheduled use of the treatment source;

responsive to receiving an activation code to enable the therapy, control the treatment source to apply the therapy to the damaged tissue in accordance with the treatment regimen;

generate usage information indicative of the therapy applied by the treatment source;

compare the usage information and the scheduled use;

generate compliance information reflecting a degree that the usage information matches the scheduled use; and

send the compliance information with a device identifier to a remote computer system, thereby causing the remote computer system to;

determine a patient identifier based upon the device identifier;

store the compliance information in association with the patient identifier; and

provide access to the compliance information to one or more users in response to receiving an inquiry associated with the patient identifier from the one or more users.

2. The medical device of claim 1, wherein:

the treatment source comprises a driver circuit coupled to an ultrasound transducer; and

the one or more processing devices are configured to control the driver circuit to produce ultrasound with the ultrasound transducer.

3. The medical device of claim 1, wherein the compliance information comprises at least one of:

a number of times that the therapy was applied by the treatment source;

a date or a time that the therapy was applied by the treatment source;

or

a duration that the therapy was applied by the treatment source.

4. The medical device of claim 1, wherein the one or more processing devices are further configured to:

detect one or more errors; and

send error information about the one or more errors with the device identifier to the remote computer system.

5. The medical device of claim 4, wherein the one or more processing devices are further configured to receive service information from the remote computer system to address the one or more errors.

6. The medical device of claim 1, wherein the one or more processing devices are configured to send the compliance information with the device identifier after the treatment source has applied the therapy a set number of times.

7. The medical device of claim 1, wherein the one or more processing devices are further configured to determine whether the activation code is valid prior to controlling the treatment source to apply the therapy.

8. The medical device of claim 7, wherein the one or more processing devices are further configured to transmit an activation acknowledgement if the activation code is determined to be valid.

9. The medical device of claim 1, wherein the activation code includes activation information indicative of a number of times that the therapy is to be applied by the treatment source.

10. The medical device of claim 1, wherein the one or more processing devices are further configured to transmit an activation acknowledgement.

11. The medical device of claim 1, wherein the treatment regimen identifies the scheduled use of the treatment source by the patient rather than another individual, and the treatment regimen indicates to apply the therapy a plurality of times.

12. The medical device of claim 1, wherein the wireless network comprises a cellular network.

13. The medical device of claim 1, wherein the device identifier identifies at least one of the treatment source or the one or more processing devices.

14. The medical device of claim 1, in combination with the remote computer system.

15. A method of operating a medical device, the method comprising:

receiving, via a wireless network or a user input to the medical device, a treatment regimen that identifies a scheduled use of a treatment source, the treatment source being configured to apply a therapy to damaged tissue of a patient to facilitate healing of the damaged tissue;

receiving an activation code to enable the therapy;

in response to receiving the activation code to enable the therapy, controlling the treatment source to apply the therapy to the damaged tissue in accordance with the treatment regimen;

generating, by one or more processing devices of the medical device, usage information indicative of the therapy applied by the treatment source;

comparing, by the one or more processing devices, the usage information and the scheduled use;

generating, by the one or more processing devices, compliance information reflecting a degree that the usage information matches the scheduled use; and

sending, by the one or more processing devices, the compliance information with a device identifier to a remote computer system, thereby causing the remote computer system to;

determine a patient identifier based upon the device identifier;

store the compliance information in association with the patient identifier; and

provide access to the compliance information to one or more users in response to receiving an inquiry associated with the patient identifier from the one or more users.

16. The method of claim 15, wherein the treatment source comprises a driver circuit coupled to an ultrasound transducer and wherein the controlling the treatment source comprises controlling the driver circuit to produce ultrasound with the ultrasound transducer.

17. The method of claim 15, wherein the compliance information comprises at least one of:

a number of times that the therapy was applied by the treatment source;

a date or a time that the therapy was applied by the treatment source;

or

a duration that the therapy was applied by the treatment source.

18. The method of claim 15, further comprising:

detecting one or more errors of the medical device; and

sending error information about the one or more errors with the device identifier to the remote computer system.

19. The method of claim 18, further comprising receiving, from the remote computer system, service information to address the one or more errors.

20. The method of claim 15, wherein the sending the compliance information with the device identifier is performed after the treatment source has applied the therapy a set number of times.

21. The method of claim 15, further comprising determining whether the activation code is valid prior to controlling the treatment source to apply the therapy.

22. The method of claim 21, further comprising transmitting an activation acknowledgement if the activation code is determined to be valid.
