Abstract

A device for detecting symptomatic jaw behaviour in a user includes a mouthpiece (1) to be worn in a mouth of the user. The mouthpiece is provided with at least one sensor (2) for electronically receiving a jaw muscle signal. The at least one sensor is herein coupled to an electronic processing element (10) with a clock element (11) and with an electronic storage element (12) for the purpose of detecting a recorded muscle signal in time and storing it in optionally processed form.

Claims

1. Device for detecting symptomatic jaw behaviour in a user, comprising a mouthpiece which is adapted and intended to be worn in a mouth of the user, which mouthpiece is provided with at least one sensor for electronically receiving a jaw muscle signal, characterized in that the at least one sensor is coupled to electronic processing means and with electronic storage means for the purpose of detecting a recorded muscle signal during a time span and storing it in optionally processed form in time.

2. Device as claimed in claim 1, characterized in that the mouthpiece comprises the processing means and the electronic storage means.

3. Device as claimed in claim 1, characterized in that the processing means comprise a programmable microprocessor which at least during operation is able and adapted, on the basis of a program code which can be programmed therein, to diagnose a recorded jaw muscle signal and to store it in diagnosed form.

4. Device as claimed in claim 3, characterized in that the processing means are able and adapted on the basis of the program code to at least discriminate between jaw muscle signals representative of specific jaw behaviour taken from a group comprising clenching of teeth and grinding of teeth for the purpose of storing these as events in time.

5. Device as claimed in claim 4, characterized in that at least the storage means are integrated into the mouthpiece and can be coupled, optionally in wired manner, to processing means located outside the mouthpiece for the purpose of electronic data exchange therewith.

6. Device as claimed in claim 1, characterized in that the mouthpiece comprises electronic power supply means.

7. Device as claimed in claim 6, characterized in that the power supply means comprise at least one electrochemical cell which is able and adapted to co-act with saliva in the mouth of the user for the purpose of generating an electric supply voltage therefrom.

8. Device as claimed in claim 6, characterized in that the power supply means comprise at least one electromagnetic coupling member which is able and adapted to intercept and convert an externally generated electromagnetic alternating field into an electronic supply voltage.

9. Device as claimed in claim 1, characterized in that the storage means are organized as an electronically readable FIFO (First In First Out) slide register.

10. Device as claimed in claim 1, characterized in that the at least one sensor extends from the mouthpiece and is able and adapted to co-act with at least one jaw element of the user for the purpose of fixing the mouthpiece in the mouth.

11. Device as claimed in claim 1, characterized in that the processing means are able and adapted to sample received muscle signals at a sampling frequency, in particular one in the order of about 1 kHz, and to store the signals in digitized form.

12. Device as claimed in claim 1, characterized in that the mouthpiece comprises at least one electrode which can be coupled to a device for administering an electrical stimulus.

13. Device as claimed in claim 12, characterized in that the at least one sensor also forms the at least one electrode.

14. Device as claimed in claim 2, characterized in that the processing means comprise a programmable microprocessor which at least during operation is able and adapted, on the basis of a program code which can be programmed therein, to diagnose a recorded jaw muscle signal and to store it in diagnosed form.
