Abstract: A chain of custody device is provided. The chain of custody device includes a strap for attaching to a body part of a patient. The chain of custody device further includes a receiver connected to the strap and operable to be connected to a physiological monitoring system via a cable. The receiver stores an identifier that is readable by the physiological monitoring system and is usable by the physiological monitoring system to verify that the physiological monitoring system is connected to a correct chain of custody device. The chain of custody device further comprises a security means for preventing undetected removal of the strap and/or receiver. A system comprising the physiological monitoring system and the chain of custody device, and a method for using such system are also described.

Abstract: A finger oximeter has fitted thereto a RF transmitter circuit so that the measured SpO2, and other physical parameters from a patient, may be transmitted telecommunicatively to a monitor device remotely located from the finger oximeter. The RF transmitter circuit is mounted on a PC board that is provided in the housing of the finger oximeter, and works in cooperation with the oximetry circuit that is also mounted on a PC board in the housing of the finger oximeter. The two PC boards may be combined as one. To receive the RF signal, a RF receiver is provided to the remote monitor device, which also includes a processing circuit for processing the incoming RF signal, and a converter circuit for converting the processed digital signal into an analog signal for display at the remote monitor device.

Abstract: Incorporated to a finger grip device are an oximeter that measures the SpO2 of the patient and a fingerprint sensor for sensing the fingerprint of the finger from which the SpO2 is measured. The sensed fingerprint is used to identify the patient. By thus establishing the identity of the patient, the measured SpO2 could readily be associated with the patient and appropriately displayed and stored, either at the patient site or remotely. The monitored data could also be readily associated with records of the patient and other physiological could data of the patient that may have been prestored in the controller to which the finger grip device is connected, or in a memory at a remote location. Mistakes in patient identification and the correspondence of wrong patient data to patients are thereby substantially reduced if not eliminated.
