Abstract

The present invention relates to a physiological monitoring device. Some embodiments of the invention allow for long-term monitoring of physiological signals. Further embodiments may also allow for the monitoring of secondary signals such as motion.

First claim

What is claimed is:

1. A physiological monitoring device configured to monitor cardiac rhythm data of a patient, the physiological monitoring device comprising:
a first housing portion and a second housing portion, wherein the first housing portion detachably couples to the second housing portion;
a first spring contact configured to electrically couple a battery to a circuit board assembly housed within the first housing portion;
a flexible substrate coupled to the second housing portion, wherein the flexible substrate comprises a border portion that is thinner than an interior portion of the flexible substrate;
an electrode embedded within a portion of the flexible substrate and configured to detect physiological signals of the patient to obtain the cardiac rhythm data; and
a flexible electrode trace embedded in the flexible substrate and configured to electrically couple the electrode to the circuit board assembly, wherein at least a portion of the flexible electrode trace is in electrical contact with a second spring contact, and wherein the second spring contact is further configured to electrically couple the flexible electrode trace to the circuit board assembly.

2. The physiological monitoring device of claim 1 , wherein the second spring contact is in physical contact with an electrocardiogram circuit interface.

3. The physiological monitoring device of claim 1 , further comprising a support post configured such that force from interaction with a trigger is applied to the support post.

4. The physiological monitoring device of claim 3 , wherein the force from interaction with the trigger is transmitted through the circuit board assembly to the support post.

5. The physiological monitoring device of claim 3 , wherein the support post is further configured to remain rigid during depression of the trigger.

6. The physiological monitoring device of claim 3 , wherein the support post is positioned below the trigger.

7. The physiological monitoring device of claim 3 , wherein the support post is positioned between the circuit board assembly and a housing portion.

8. The physiological monitoring device of claim 7 , wherein the housing portion comprises the second housing portion.

9. The physiological monitoring device of claim 7 , wherein the support post is integral with the housing portion.

10. The physiological monitoring device of claim 3 , wherein the force is transmitted to the support post without creating a bending moment.

11. The physiological monitoring device of claim 1 , wherein the first housing portion comprises a rigid housing configured to prevent deformation of the circuit board assembly in response to movement of the patient.

12. The physiological monitoring device of claim 1 , wherein the flexible substrate comprises an electrode-supporting section.

13. The physiological monitoring device of claim 1 , further comprising a gasket configured to make a housing watertight, wherein the housing comprises at least the first housing portion and the second housing portion.

14. The physiological monitoring device of claim 1 , wherein the flexible electrode trace is sandwiched between a first layer and a second layer of the flexible substrate.

15. The physiological monitoring device of claim 1 , wherein the circuit board assembly is substantially rigid.

16. The physiological monitoring device of claim 1 , further comprising a trigger configured to cause a signal to be relayed to the circuit board assembly in response to user interaction with the trigger.

17. The physiological monitoring device of claim 16 , wherein the trigger comprises a button.

18. The physiological monitoring device of claim 1 , further comprising an adhesive layer located on at least a portion of the flexible substrate and configured to adhere to skin of the patient.

19. The physiological monitoring device of claim 18 , wherein the adhesive layer is configured to adhere to the skin of the patient for at least 7 days enabling the physiological monitoring device to monitor the cardiac rhythm data of the patient for at least 7 days.

20. The physiological monitoring device of claim 1 , further comprising an LED indicator configured to indicate activation.

21. The physiological monitoring device of claim 1 , further comprising a second electrode embedded within a second portion of the flexible substrate.

22. The physiological monitoring device of claim 1 , wherein the flexible electrode trace electrically couples the electrode to the circuit board assembly via the second spring contact.
