Abstract

A patient cable has a duo sensor connector having a first socket section and a second socket section. The first socket section is configured to removably attach a two-wavelength sensor. The second socket section in conjunction with the first socket section is configured to removably attach a multiple wavelength sensor in lieu of the two-wavelength sensor. A circuit housed in the duo sensor connector converts emitter array drive signals adapted for the multiple wavelength sensor into back-to-back emitter drive signals adapted for the two-wavelength sensor when attached.

Claims

1. A patient cable for connecting a patient monitor to an optical sensor comprising:

a duo connector means for establishing communications between a monitor and one of a two-wavelength sensor having a conventional connector and a multiple wavelength sensor connector; and

an information means for identifying which of the sensors is attached to the duo connector means.

2. The patient cable according to claim 1 further comprising:

a switching means for converting array drive signals from the monitor to back-to-back drive signals for the two-wavelength sensor; and

a housing means for mounting the switching means with the duo connector means.

3. The patient cable according to claim 2 further comprising a configuration means for achieving improved noise isolation for a sensor signal when the multiple wavelength is attached to the duo connector means.

4. The patient cable according to claim 3 further comprising an overmold means for housing the duo connector means and the switching means and for creating a bend relief means.

5. A patient cable for connecting a patient monitor to an optical sensor comprising:

a duo connector configured to establish communications between a monitor and one of a two-wavelength sensor having a conventional connector and a multiple wavelength sensor connector; and

a network line configured to carry an information element, wherein the information element identifies which of the sensors is attached to the duo connector.

6. The patient cable according to claim 5 further comprising:

a plurality of switches for converting array drive signals from the monitor to back-to-back drive signals for the two-wavelength sensor; and

a housing assembly for mounting the plurality of switches with the duo connector.

7. The patient cable according to claim 6 further comprising drive signal pins housed in a first section, wherein the switches are configured to selectively ground the drive signal pins in the first section for achieving improved noise isolation for a sensor signal when the multiple wavelength is attached to the duo connector.

8. The patient cable according to claim 7 further comprising an overmold for housing the duo connector and the plurality of switches and for creating a bend relief.

9. A patient cable method comprising the steps of:

providing a duo connector configured to establish communications between a monitor and one of a two-wavelength sensor having a conventional connector and a multiple wavelength sensor connector; and

providing a network line configured to carry an information element, wherein the information element identifies which of the sensors is attached to the duo connector.

10. The patient cable method according to claim 9 comprising the further steps of:

providing a plurality of switches for converting array drive signals from the monitor to back-to-back drive signals for the two-wavelength sensor; and

providing a housing assembly for mounting the plurality of switches with the duo connector.

11. The patient cable according to claim 10 comprising the further step of grounding drive signal pins so as to achieve improved noise isolation for a sensor signal when the multiple wavelength is attached to the duo connector.

12. The patient cable according to claim 11 comprising the further step of providing an overmold for housing the duo connector and the plurality of switches and for creating a bend relief.
