Abstract

A wearable cardioverter defibrillator monitor case includes a housing configured to surround a defibrillator electronics assembly, a front cover removably attachable to the housing, and a rear cover removably attachable to the housing. The wearable cardioverter defibrillator case has a shock indicator positioned on the housing at an interface between the housing and the front cover.

Claims (36)

1. A wearable cardioverter defibrillator monitor case, comprising:

a housing configured to surround a defibrillator electronics assembly;

a battery conditioning system comprising a battery housing configured to receive a rechargeable battery and a detector configured to sense a charge level of the rechargeable battery;

a front cover removably attachable to the housing; and

a rear cover removably attachable to the housing,

wherein the wearable cardioverter defibrillator monitor case comprises a non-powered shock indicator positioned on the housing at an interface between the housing and the front cover.

2. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the shock indicator is positioned within a recess.

3. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the shock indicator is a mechanical shock indicator.

4. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the front cover includes a window.

5. The wearable cardioverter defibrillator monitor case of claim 4 , wherein the window is positioned on the front cover such that the shock indicator is visible when the front cover is removably attached to the housing.

6. The wearable cardioverter defibrillator monitor case of claim 1 , further comprising a second shock indicator, wherein the shock indicator and the second shock indicator are positioned on different components of the wearable cardioverter defibrillator monitor case.

7. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the front cover is sized to substantially cover a front face of the housing when removably attached to the housing.

8. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the rear cover is sized to substantially cover a rear face of the housing when removably attached to the housing.

9. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the front cover or the rear cover is configured to conceal a plurality of attachment devices that attach the defibrillator electronics assembly to the housing.

10. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the front cover and the rear cover are independently detachable from the housing.

11. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the case is configured to be detached from the cardioverter defibrillator electronics assembly by removal of a plurality of attachment devices.

12. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the front cover is configured to conceal the shock indicator from view when the front cover is removably attached to the housing.

13. A wearable cardioverter defibrillator monitor, comprising:

a monitor case having:

a housing;

a front cover removably attachable to the housing;

a battery conditioning system comprising a battery housing configured to receive a rechargeable battery comprising a detector configured to sense a charge level of the rechargeable battery;

a rear cover removably attachable to the housing; and

a non-powered shock indicator positioned on the case at an interface between the housing and the front cover;

a cardioverter defibrillator electronic assembly positioned inside the monitor case; and

a battery that is removably receivable within the battery conditioning system battery housing.

14. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the shock indicator is a chemical shock indicator.

15. The wearable cardioverter defibrillator monitor case of claim 13 , wherein the shock indicator is a mechanical shock indicator.

16. The wearable cardioverter defibrillator monitor case of claim 13 , wherein the shock indicator is a chemical shock indicator.

17. The wearable cardioverter defibrillator monitor case of claim 13 , further comprising:

a second shock indicator,

wherein the shock indicator and the second shock indicator are positioned on different components of the wearable cardioverter defibrillator monitor case.

18. The wearable cardioverter defibrillator monitor case of claim 17 , wherein the second shock indicator is a mechanical shock indicator.

19. The wearable cardioverter defibrillator monitor case of claim 17 , wherein the second shock indicator is a chemical shock indicator.

20. The wearable cardioverter defibrillator monitor case of claim 1 , wherein the detector is configured to detect the charge level of the rechargeable battery as a fraction of a capacity of the rechargeable battery.

21. The wearable cardioverter defibrillator monitor case of claim 13 , wherein the detector is configured to detect the charge level of the rechargeable battery as a fraction of a capacity of the rechargeable battery.
