Methods and systems for reducing interference in stimulation treatment
Systems and methods are provided for reducing stimulation interference between two stimulation modules positioned on a user's body, which may be used in stimulation systems without a central treatment controller. Systems and methods are also provided for stimulation treatment using multiple independent stimulators wirelessly managed by a remote management device.
1.

in response to not detecting the signal indicative of a stimulation pulse from the second stimulation transducer device at the first body site, deliver a stimulation pulse at the first body site in accordance with the received treatment information; and
in response to detecting the signal indicative of a stimulation pulse from the second stimulation transducer device, delay the delivery of stimulation treatment of the first stimulation transducer device for a first delay period and at the end of the first delay period, deliver a stimulation pulse at the first body site.

3. The system of claim 1 , wherein the first stimulation transducer device includes circuitry that filters the signal detected during the first detection period.
4. The system of claim 1 , wherein the first stimulation transducer device includes circuitry that ascribes a priority to the signal detected during the first detection period.
5. The system of claim 1 , wherein the first stimulation transducer device includes a processor that causes a delay of the delivery of stimulation treatment by the first stimulation transducer device.
6. The system of claim 5 , further comprising a counter for storing a value indicative of a number of times that stimulation treatment is delivered by the second stimulation transducer device after delaying the delivery of stimulation treatment.
7. The system of claim 6 , further comprising a processor configured to determine when the value stored in the counter exceeds a retry limit.
8. The system of claim 7 , further comprising an electronic indicator that is triggered when the retry counter reaches a retry limit.
9. The system of claim 6 , wherein the first stimulation transducer device is further configured to transmit a signal to a management module when the value stored in the counter exceeds the retry limit.
10. The system of claim 5 , wherein first stimulation transducer device is further configured to provide a marking pulse after delaying the delivery of stimulation treatment and prior to delivery of stimulation treatment.
11. The system of claim 1 , further comprising the second stimulation transducer device, wherein the second stimulation transducer device has circuitry that generates and detects stimulation and is configured to:
receive treatment information from the first processor,
deliver electrical stimulation treatment to a user in accordance with the received treatment information,
detect a signal indicative of stimulation treatment delivered to the user at the first body site by the first stimulation transducer device, and
in response to detecting the signal, delay the delivery of stimulation treatment.
12. The system of claim 1 , wherein the communication circuitry is wireless communication circuitry.
13. The system of claim 1 , wherein the stimulation treatments comprise a succession of stimulation pulses.
14. The system of claim 1 , wherein the circuitry is further configured to monitor for the signal indicative of stimulation treatment delivered to the user by the second stimulation transducer device at predetermined intervals.
15. The system of claim 1 , wherein the first delay period comprises a first random duration.
16. The system of claim 15 , wherein the first random duration is selected from between a lower duration limit and an upper duration limit.
17. The system of claim 1 , wherein the circuitry is further configured to generate a marking pulse with the first stimulation transducer device.
18. The system of claim 1 , wherein the first stimulation transducer device is further configured to, after delaying for a first delay period and before delivering a stimulation pulse at the first body site, iteratively detect whether a signal indicative of a stimulation pulse delivered to the user by the second stimulation transducer device is present, in response to not detecting the signal indicative of a stimulation pulse from the second stimulation transducer device, deliver a stimulation pulse at the first body site in accordance with the received treatment information, and in response to detecting the signal from the second stimulation transducer device, delay the delivery of stimulation treatment of the first stimulation transducer device for another delay period.
