Abstract

A prehospital telemedicine system comprises a physiologic monitor; an electronic patient care reporting system (ePCR) system; and a point-of-care blood analyzer communicatively coupled to the physiologic monitor and the ePCR system. The point-of-care blood analyzer is configured to perform an analysis of a blood sample based on an indication of a need for a specific blood analysis provided by one of the physiologic monitor and the ePCR system, and to automatically transmit a result of the analysis to a remote data receiving system. The indication of a need for a specific blood analysis may be based upon any one of the following: vital signs data obtained for a patient by the physiologic monitor; and/or current documentation or past medical history captured on or available through the ePCR system.

First claim

We claim:

1. A prehospital telemedicine system, comprising:
a gateway device in a local area network, the gateway device configured to communicate with a remote data receiving system of a medical facility over a cellular link;
a point-of-care (POC) blood analyzer communicatively connected in the local area network to the gateway device, wherein the POC blood analyzer is configured to begin analysis of a blood sample of a patient before the patient arrives at the medical facility and provide a result of the analysis of the blood sample to the gateway device; and
an electronic patient care reporting (ePCR) system communicatively connected in the local area network to the gateway device, wherein the ePCR system is configured to collect patient information of the patient and provide the patient information to the gateway device, wherein the ePCR system is configured to restrict use of the POC blood analyzer prior to completion of an electronic checklist and taking a combination of vital signs, wherein completion of the electronic checklist and the taking of the combination of vital sign triggers the ePCR to provide an electronic signal to the POC blood analyzer that enables the point-of-care blood analyzer to perform the analysis, and
wherein the gateway device is configured to transmit the result of the analysis of the blood sample and the patient information to the remote data receiving system of the medical facility.

2. The prehospital telemedicine system of claim 1 , wherein the patient information comprises patient demographic information, and wherein the gateway device is configured to transmit the patient demographic information together with the result of the analysis of the blood sample.

3. The prehospital telemedicine system of claim 2 , wherein the patient demographic information is entered by a prehospital care provider using the ePCR system.

4. The prehospital telemedicine system of claim 3 , wherein the ePCR system is configured to prompt the prehospital care provider to enter the patient demographic information.

5. The prehospital telemedicine system of claim 2 , wherein the ePCR system is configured to obtain the patient demographic information from an electronic record.

6. The prehospital telemedicine system of claim 5 , wherein the electronic record is an electronic medical record.

7. The prehospital telemedicine system of claim 1 , wherein prehospital telemedicine system is further configured to: combine the result of the analysis of the blood sample with the patient information; and transmit information derived from a combination of the result of the analysis of the blood sample with the patient information to the remote data receiving system of the medical facility.

8. The prehospital telemedicine system of claim 7 , wherein the patient information comprises a complaint, and wherein the combination of the result of the analysis and the patient information comprises the complaint.

9. The prehospital telemedicine system of claim 7 , wherein the patient information comprises a physical assessment, and wherein the combination of the result of the analysis and the patient information comprises the physical assessment.

10. The prehospital telemedicine system of claim 1 , further comprising a physiologic monitor, wherein the local area network is a local area network of the physiologic monitor.

11. The prehospital telemedicine system of claim 10 , wherein the gateway device is a component of the physiologic monitor.

12. The prehospital telemedicine system of claim 1 , wherein the gateway device is a component of the ePCR system.

13. The prehospital telemedicine system of claim 1 , wherein the POC blood analyzer is configured to measure creatine kinase-MB (CK-MB), myoglobin, cardiac troponin (cTn), lactate, or D-dimer.

14. The prehospital telemedicine system of claim 1 , wherein the ePCR system is further configured to: determine, based at least on the patient information, that it is appropriate to analyze the blood sample; and cause display of a prompt indicating that it is appropriate to analyze the blood sample.

15. The prehospital telemedicine system of claim 1 , further comprising a physiologic monitor configured to obtain physiologic data, wherein the gateway device is configured to transmit the physiologic data with the result of the analysis of the blood sample to the remote data receiving system of the medical facility.

16. A method comprising:
analyzing a blood sample of a patient using a point-of-care (POC) blood analyzer of a prehospital telemedicine system before the patient arrives at a medical facility;
providing, by the POC blood analyzer, a result of the analyzing of the blood sample to a gateway device in a local area network, wherein the gateway device is configured to communicate with a remote data receiving system of the medical facility over a cellular link;
collecting patient information of the patient using an electronic patient care reporting (ePCR) system communicatively connected in the local area network to the gateway device, wherein the POC blood analyzer is restricted from analyzing the blood sample prior to completion of an electronic checklist and taking a combination of vital signs, and wherein completion of the electronic checklist and the taking of the combination of vital sign triggers the ePCR to provide an electronic signal to the POC blood analyzer that enables the point-of-care blood analyzer to analyze the blood sample;
providing, by the ePCR system, the patient information to the gateway device; and
transmitting, by the gateway device, the result of the analysis of the blood sample and the patient information to the remote data receiving system of the medical facility.

17. The method of claim 16 , wherein the prehospital telemedicine system is carried in an emergency services vehicle.

18. A local area network of a prehospital telemedicine system, the local area network comprising:
a gateway device configured to communicate with a remote data receiving system of a medical facility over a cellular link;
a point-of-care (POC) blood analyzer configured to begin analysis of a blood sample of a patient before the patient arrives at the medical facility and provide a result of the analysis of the blood sample to the gateway device, wherein the POC blood analyzer is restricted from analyzing the blood sample prior to completion of an electronic checklist and taking a combination of vital signs; and
an electronic patient care reporting (ePCR) system configured to collect patient information of the patient and provide the patient information to the gateway device, wherein completion of the electronic checklist and the taking of the combination of vital sign triggers the ePCR to provide an electronic signal to the POC blood analyzer that enables the point-of-care blood analyzer to analyze the blood sample,
wherein the gateway device is configured to transmit the result of the analysis of the blood sample and the patient information to the remote data receiving system of the medical facility.

19. The local area network of claim 18 , wherein the gateway device is configured to transmit an indication that the analysis of the blood sample is in progress or the result of the analysis of the blood sample to the remote data receiving system before the patient arrives at the medical facility.
