Abstract

Claims (25)

1. A wearable cardioverter defibrillator (WCD) system, comprising:

a WCD monitor having a receptacle, the WCD monitor configured to deliver high voltage (HV) signals and receive low voltage (LV) signals, wherein the HV signals comprise a defibrillating electrical shock for delivery to a person and the LV signals comprise electrocardiogram (ECG) signals received from the person;

a first mating shield disposed within the receptacle; and

a WCD connector comprising a plurality of HV pins and LV pins, the WCD connector further having a second mating shield disposed around the plurality of HV pins and LV pins, the second mating shield configured to mate with the first mating shield, wherein the mated first and second mating shields are configured to substantially shield the HV signals and the LV signals from electrical noise.

2. The WCD system of claim 1 , wherein the second mating shield comprises a metal shield disposed around the plurality of HV pins and LV pins.

3. The WCD system of claim 2 , wherein the metal shield comprises a die cast zinc alloy with nickel plating.

4. The WCD system of claim 1 , wherein the first mating shield comprises a metal shield having one or more resilient mating structures to electrically contact the first mating shield.

5. The WCD system of claim 4 , wherein the metal shield comprises a beryllium copper alloy.

6. The WCD system of claim 1 , wherein the plurality of HV pins and LV pins are arranged in a substantially trapezoidal layout.

7. A wearable cardioverter defibrillator (WCD) connector comprising:

a plurality of low voltage (LV) electrical pins, the plurality of LV electrical pins configured to receive LV signals from a person, the LV signals include electrocardiogram (ECG) signals from the person;

a plurality of high voltage (HV) electrical pins, the plurality of HV electrical pins configured to deliver HV signals to the person, the HV signals comprising a defibrillating shock; and

one or more electrical shields disposed around the plurality of LV and HV electrical pins, the one or more electrical shields configured to substantially shield the HV signals and the LV signals from electrical noise.

8. The WCD connector of claim 7 , wherein the plurality of LV and HV electrical pins are arranged in a substantially trapezoidal layout.

9. The WCD connector of claim 7 , wherein the one or more electrical shields comprise metal.

10. The WCD connector of claim 9 , wherein the metal comprises a die cast zinc alloy with nickel plating.

11. The WCD connector of claim 7 , wherein the one or more electrical shields comprise metal having one or more resilient mating structures.

12. The WCD connector of claim 11 , wherein the one or more electrical shields comprise beryllium copper alloy.

13. A wearable cardioverter defibrillator (WCD) monitor comprising:

a housing;

a plurality of low voltage (LV) receptacle contacts, the plurality of LV receptacle contacts configured to receive a plurality of LV electrical pins and receive, via the plurality of LV electrical pins, LV signals having electrocardiogram (ECG) signals from a person;

a plurality of high voltage (HV) receptacle contacts, the plurality of HV receptacle contacts configured to receive a plurality of HV electrical pins and deliver, via the plurality of HV electrical pins, HV signals to the person, the HV signals comprising a defibrillating shock; and

a shield, the shield configured to electrically shield the LV signals and the HV signals from electrical noise between the WCD monitor and a WCD connector.

14. The WCD monitor of claim 13 , wherein the shield comprises a metal shield having one or more resilient mating structures configured to electrically contact an electrical shield of the WCD connector.

15. The WCD monitor of claim 14 , wherein the metal shield comprises a beryllium copper alloy.
