Abstract

A body worn mobile medical monitoring device configured to minimize cable wiring from a sensor by placement of one or more sensor communication ports. The body worn mobile medical monitoring device includes a housing securable on a lower arm of a patient, a display, and a sensor communication port positioned on a side of the housing and configured to face a hand of the lower arm of the patient when the mobile medical monitoring device is mounted to the lower arm of the patient. The sensor communication port provides wired communication with a pulse oximetry sensor attached to a digit of the hand of the patient, and is positioned on the side of the housing such that a path from the port on the side of the housing to the digit of the patient is shorter than any other path from any other side of the housing to the digit.

First claim

What is claimed is:

1. A body worn mobile medical monitoring device configured to minimize cable wiring from a sensor by placement of one or more sensor communication ports, the mobile medical monitoring device comprising:
a housing configured to be secured on a lower arm of a patient being monitored via a strap extending around the lower arm of the patient;
a display positioned on a face of the housing, opposite the strap, so as to be visible to a user;
a first sensor communication port positioned on a side of the housing and configured to face a hand of the lower arm of the patient when the mobile medical monitoring device is mounted to the lower arm of the patient, wherein:
the side of the housing faces the hand of the lower arm of the patient of the patient when the mobile medical monitoring device is mounted to the lower arm of the patient,
the first sensor communication port is configured to provide wired communication with a pulse oximetry sensor attached to a digit of the hand of the patient,
the wired communication with the pulse oximetry sensor provided at least partly in the analog domain, and
the first sensor communication port is positioned on the side of the housing such that a path from the first sensor communication port on the side of the housing to the digit of the patient is substantially perpendicular to the side of the housing and shorter than any other path from any other side of the housing to the digit of the patient;

a plurality of additional sensor communications ports positioned on the housing and configured to provide wired communication with a plurality of additional physiological sensors at least partly in the digital domain; and
one or more processors and a transmitter configured to:
display, on the display, physiological measurements derived from the pulse oximetry sensor and the plurality of additional physiological sensors; and
wirelessly transmit information indicative of the physiological measurements to a remote computing device.

2. The mobile medical monitoring device of claim 1 , wherein the wired communication with the pulse oximetry sensor is provided via a tail extending from the pulse oximetry sensor.

3. The mobile medical monitoring device of claim 2 , wherein the tail comprises a cable that is configured to be removably attachable to the first sensor communication port.

4. The mobile medical monitoring device of claim 3 , wherein a length of the cable corresponds to the path from the sensor communication port on the side of the housing to the digit of the patient.

5. The mobile medical monitoring device of claim 3 , wherein the cable is appropriately sized based on the path from the sensor communication port on the side of the housing to the digit of the patient.

6. The mobile medical monitoring device of claim 3 , wherein the path from the sensor communication port on the side of the housing to the digit of the patient runs at least partly along a backside of the hand of the patient.

7. The mobile medical monitoring device of claim 1 , wherein the face of the housing comprises a single user interface.

8. The mobile medical monitoring device of claim 7 , wherein the single user interface comprises the display.

9. The mobile medical monitoring device of claim 8 , wherein:
the housing comprises a back side that is opposite the face of the housing,
the strap is mountable to the back side of the housing, and
the face of the housing is raised from the strap and the lower arm of the patient to enable positioning of the first sensor communication port on the side of the housing between the lower arm of the patient and the face of the housing.

10. The mobile medical monitoring device of claim 9 , wherein:
the front side of the housing comprises a bezel and the display, and
a top of the first sensor communication port is located below the face of the housing.

11. The mobile medical monitoring device of claim 10 , wherein the display is positioned centrally on the face of the housing.

12. The mobile medical monitoring device of claim 11 , wherein the display positioned on the face of the housing is sized such that the display covers most of a length of a shortest dimension of the face of the housing.

13. A body worn, battery-powered medical monitoring device configured to provide on-patient and remote monitoring of patient physiological parameters, the medical monitoring device comprising:
a battery configured to provide power to the medical monitoring device such that the medical monitoring device may operate without a wired power connection;
a case configured to house the battery;
a strap configured to attach the case to an arm of a patient and be mountable to the case;
a first communications port positioned on a face of a side of the case configured to be nearest to a hand of the arm of the patient when the case is mounted to the arm of the patient, the first communications port configured to removably couple with a cable of a finger- or thumb-type pulse oximetry sensor and positioned on the face of the side of the case to provide a path from the first communications port to a digit of the hand of the patient that avoids tangling of the cable, the first communications port configured such that the cable perpendicularly extends from the face of the side of the case when the cable is coupled to the first communications port;
a second communications port configured to provide wired communications with a second physiological sensor arrangement at least partly via digital communications;
a third communications port configured to provide wired communications with a third physiological sensor arrangement;
a display configured to provide real time measurements of patient physiological parameters based at least in part on data obtained from at least the pulse oximetry sensor via the first communications port; and
a transmitter configured to wirelessly transmit information indicative of real time measurements of patient physiological parameters based at least in part on data obtained from the pulse oximetry sensor via the first communications port.

14. The medical monitoring device of claim 13 , wherein the path from the first communications port to a digit of the hand is shorter than any path from any communications port located on any other side of the case to the digit of the hand.

15. The medical monitoring device of claim 13 further comprising:
one or more hardware processors configured to:
process the data obtained from the pulse oximetry sensor; and
determine, based at least in part on the data, the real time measurements of patient physiological parameters.

16. The medical monitoring device of claim 15 , wherein:
the one or more hardware processors are further configured to:
receive additional data from at least the second physiological sensor arrangement and the third physiological sensor arrangement;
determine, based at least in part on the additional data, real time measurements of additional patient physiological parameters; and
cause to be displayed, on the display, the real time measurements of additional patient physiological parameters; and

the transmitter is further configured to:
wirelessly transmit information indicative of real time measurements of additional patient physiological parameters based at least in part on the additional data.

17. The medical monitoring device of claim 16 , wherein the display is positioned on a front, user-facing side of the case to enable a user to view the real time measurements of patient physiological parameters and the real time measurements of addi
