Patent ID: 8273053

Claim:
An intraosseous (IO) fluid delivery and patient status system, the IO system comprising: an IO infusion device configured to provide access to an IO space in a bone of a patient, the IO infusion device comprising: a bone portal comprising a fluid delivery channel, the bone portal having a proximal end and a distal end, the distal end configured to be inserted into the bone; and a fluid delivery conduit configured to be coupled to the proximal end of the bone portal so as to provide fluid access to the fluid delivery channel of the bone portal; and a patient status sensor configured to monitor at least heart rate and respiration rate of the patient, the patient status sensor comprising: a substrate comprising an adhesive component configured to adhere the patient status sensor to the patient; a pair of electrodes disposed in or on the substrate the pair of electrodes configured to receive an electrical signal from the body of the patient and in response to provide a body signal comprising a single-channel electrocardiogram (ECG) signal; a visual indicator; a processor configured to (a) receive and process the body signal from the pair of electrodes in order to determine measurements of heart rate and respiration rate, the heart rate determined from the single-channel ECG signal, (b) determine patient status based at least in part on: (b1) the measurement of the heart rate and one or more heart rate limits and (b2) the measurement of the respiration rate and one or more respiration rate limits, and (c) output a patient status signal to the visual indicator, the visual indicator configured to output visual information indicative of the patient status; and a power source configured to be electrically connected to the visual indicator and the processor.
