Abstract

A medical network service can replace or supplement some or all of an expensive internally staffed clinical facility network with a cloud-based networking service. The medical network service in certain embodiments can provide networking services via software as a service technologies, platform as a service technologies, and/or infrastructure as a service technologies. The medical network service can provide these services to large existing clinical facilities such as metropolitan hospitals as well as to smaller clinical facilities such as specialized surgical centers. The medical network service can replace and/or supplement existing IT networks in hospitals and other clinical facilities and can therefore reduce costs and increase security and reliability of those networks. In addition, the medical network service can provide synergistic benefits that can improve patient outcomes and patient care. In addition, a medical edge router can provide redundant communications features for transmitting patient data to the medical network service.

First claim

What is claimed is:

1. A system for providing patient monitoring data over a network, the system comprising:
a medical edge router having one or more hardware processors, the medical edge router comprising:
a plurality of inputs in communication with a plurality of point of care devices;
a plurality of wired outputs in communication with a plurality of wired routers or switches associated with first and second Internet service providers (ISPs);
a traffic inspector configured to:
receive input packets from the plurality of point of care devices, the input packets comprising information related to patient monitoring data, the information related to patient monitoring data comprising physiological parameter values, trend data representing trends in the physiological parameter values, and patient monitoring alarms representing the physiological parameter values reaching alarm limits, and
analyze the input packets to identify the patient monitoring alarms in the input packets; and

a routing module comprising routing tables populated with routing information generated according to a Border Gateway Protocol, the routing module configured to:
update the routing tables over time using the Border Gateway Protocol;
receive an indication from the traffic inspector that the patient monitoring alarms are contained in some of the input packets;
in response to receiving the indication, route first ones of the input packets that do not correspond to the patient monitoring alarms over a first communications channel corresponding to the first ISP and route second ones of the input packets over a second communications channel corresponding to at least the second ISP in response to detecting the patient monitoring alarms in the second input packets;
in response to determining that the first and second communications channels are unavailable, route a reduced form of the input data over a third communications channel having lower second bandwidth than a first bandwidth of the first and second channel by:
prioritizing the patient monitoring alarms over the physiological parameter values, such that the patient monitoring alarms are transmitted over the third communications channel instead of the physiological parameter values based on the second bandwidth, and
prioritizing the physiological parameter values over the trend data which consumes greater bandwidth than the physiological parameter values, such that the physiological parameter values are transmitted over the third communications channel instead of the trend data based on the second bandwidth.

2. The system of claim 1 , wherein the routing module is further configured to perform one or both of said transmitting the first packets and said transmitting the second packets by at least transmitting the respective first or second packets to a medical network service.

3. The system of claim 1 , wherein the routing module is further configured to perform one or both of said transmitting the first packets and said transmitting the second packets by at least transmitting the respective first or second packets to a clinician device.

4. The system of claim 1 , wherein the second packets comprise the physiological parameter values of the patient as well as data representing the patient monitoring alarms.

5. The system of claim 1 , wherein the routing module is further configured to transmit the first packets by at least transmitting the first packets through a first internet service provider.

6. The system of claim 5 , wherein the routing module is further configured to transmit the second packets by at least transmitting the second packets through a second internet service provider and through the first internet service provider.

7. The system of claim 5 , wherein the routing module is further configured to transmit the second packets by at least transmitting the second packets through a cellular network and through the first internet service provider.

8. The system of claim 1 , wherein the routing module is further configured to transmit the second packets by at least transmitting the second packets through a wired internet service provider and through a wireless internet service provider.

9. The system of claim 1 , wherein the third communications channel corresponds to a short message service (SMS).
