Abstract

An electronic module for a modular patient care system is disclosed. The electronic module can include a housing having an attachment side configured to releasably attach to an adjacent electronic module. A latch mechanism can be configured to engage a catch member on the adjacent electronic module to secure the attachment side to the adjacent electronic module. An electrical connector positioned on the attachment side can be configured to electrically connect to an adjacent electrical connector on the adjacent electronic module. A sensor coupled to the housing can be configured to detect movement of the latch mechanism indicative of at least one of engagement or disengagement of the latch mechanism from the adjacent electronic module.

First claim

What is claimed is:

1. A module for a patient care system, the module comprising:
a housing having an attachment side configured to releasably attach to an adjacent electronic module;
a latch mechanism configured to engage a catch member on the adjacent electronic module to secure the attachment side to the adjacent electronic module;
an electrical connector positioned on the attachment side and configured to electrically connect to an adjacent electrical connector on the adjacent electronic module; and
a sensor coupled to a latch extension extending from the latch mechanism and configured to be disposed within the housing and detect movement of the latch mechanism.

2. The module of claim 1 , wherein the sensor comprises a hall effect sensor.

3. The module of claim 1 , wherein the sensor comprises an optical interrupt sensor.

4. The module of claim 1 , wherein the sensor comprises a capacitance sensor.

5. The module of claim 1 , wherein the sensor comprises an inductance sensor.

6. The module of claim 1 , wherein the latch mechanism includes a rotatable latch body.

7. The module of claim 6 , wherein the sensor is configured to detect rotation of the latch body.

8. The module of claim 1 , wherein the latch mechanism includes a translatable latch body.

9. The module of claim 8 , wherein the sensor is configured to detect translation of the latch body.

10. The module of claim 1 , wherein the latch mechanism includes a latch body configured to rotate and translate.

11. The module of claim 10 , wherein the sensor is omni-directional and is configured to detect rotation and translation of the latch body.

12. A module for a patient care system, the module comprising:
a housing having an attachment side configured to releasably attach to an adjacent electronic module; and
an electrical connector positioned on the attachment side and configured to electrically connect to an adjacent electrical connector on the adjacent electronic module, wherein the electrical connector comprises a plurality of connector pins, a first connector pin of the plurality of connector pins has a first height and a second connector pin of the plurality of connector pins has a second height, the first height being different than the second height, and at least one connector pin is retained by a radial elastomeric seal.

13. The module of claim 12 , wherein the radial elastomeric seal comprises a thermoplastic elastomer.

14. The module of claim 12 , wherein the radial elastomeric seal is bonded to the electrical connector.

15. The module of claim 12 , wherein the radial elastomeric seal is mechanically interlocked to the electrical connector.

16. The module of claim 12 , further comprising a plurality of contact springs spaced apart from the plurality of connector pins, wherein the plurality of connector pins are configured to contact the plurality of contact springs.

17. The module of claim 16 , wherein a first contact spring of the plurality of contact springs has a first height and a second contact spring of the plurality of contact springs has a second height, the first height being different than the second height.

18. The module of claim 12 , wherein the radial elastomeric seal comprises an aperture and the first connector pin extends through the aperture.

19. The module of claim 18 , wherein an aperture diameter is undersized relative to the first connector pin.
