Wireless sensors in medical environments
Monitoring a patient can include a vital sign device including a skin contact and a demodulator circuit in communication with the electrically conductive skin contact, the demodulator circuit including: a physiological waveform data processing module configured to process the waveform data received from the electrically conductive skin contact; and a digitally encoded data processing module configured to detect and decode digitally encoded data modulated at the carrier frequency. Also included can be a signal conductive blanket including an extended touch point. A clinician contacts the extended touch point of the signal conductive blanket and the patient monitoring device to connect the vital sign device and the patient monitoring device.
1. A method for establishing a connection between a wireless vital sign device and a patient monitoring device, the method comprising:
attaching the wireless vital sign device to a patient;
providing a signal conductive blanket, at least some portion of the signal conductive blanket touching the patient;
contacting a portion of the signal conductive blanket with a first clinician body part;
contacting a portion of the patient monitoring device with a second clinician body part, the patient monitoring device being detached from the patient; and
confirming, on the patient monitoring device, connection between the vital sign device and the patient monitoring device.
2. The method of claim 1 , further comprising contacting an extended touch point on the signal conductive blanket with the first clinician body part.
3. The method of claim 1 , wherein the first clinician body part is a first hand of a clinician and the second clinician body part is a second hand of the clinician, the method further comprising:
allowing the first hand of the clinician to touch an extended touch point on the signal conductive blanket; and
allowing the second hand of the clinician to touch the portion of the patient monitoring device.
4. The method of claim 1 , further comprising forming multiple extended touch points on the signal conductive blanket.
5. The method of claim 4 , further comprising forming multiple touch pads on the signal conductive blanket.
6. The method of claim 5 , further comprising forming the vital sign device to include an electrically conductive skin contact configured to obtain waveform data including waveform data modulated at a carrier frequency, and a demodulator circuit in communication with the electrically conductive skin contact.
7. The method of claim 1 , further comprising contacting an extended touch point on the signal conductive blanket with the first clinician body part, the extended touch point located away from the patient, and contacting an electrically conductive skin contact on the patient monitoring device with the second clinician body part.
