Abstract

Embodiments of a patient status sensor can be applied to a patient or trauma victim to provide a quick visual and/or audible indication of the patient's vital signs (e.g., respiration, heart rate, or other vital signs). Certain embodiments are configured as an adhesive patch that includes electrodes for measuring heart rate (and respiration in some implementations), a processor configured to perform calculations for determining one or more vital signs using information from the electrodes, and audible or visual indicators to communicate information about vital signs or patient status to a medical attendant. Certain embodiments include an access opening for providing intraosseous delivery of fluids to bone marrow (e.g., through sternal or long bone) and can be integrated or used with an intraosseous delivery system. Certain embodiments include wired or wireless components to communicate vital signs or patient status to an external monitoring device.

Dependent claims

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.

a pair of electrodes disposed in or on the substrate, the patient status sensor configured to output an impedance signal via the pair of electrodes to the body of the patient, the pair of electrodes configured to receive from the body of the patient an electrical signal comprising a single-channel electrocardiogram (ECG) signal and a modulation of the impedance signal;
a processor disposed in or on the substrate, the processor configured to:
receive and process the electrical signal from the pair of electrodes to determine a measurement of heart rate from the single-channel ECG signal and respiration rate from the modulation of the impedance signal;
determine patient status based at least in part on (a) the measurement of the heart rate and one or more heart rate limits and (b) the measurement of the respiration rate and one or more respiration rate limits;
and
output a patient status signal to the visual indicator in response to the determination of the patient status, the visual indicator configured to output visual information indicative of at least one of the heart rate, the respiration rate, and the patient status;
and
a power source disposed in or on the substrate, the power source configured to be electrically connected to the plurality of electrodes, the visual indicator, and the processor.
