First Claim
Patent Images
1. A spot check monitoring system using a monitor configured to accept signals responsive to light attenuated by body tissue comprising:
- a housing that houses;
a minimally invasive glucose reader configured to read a glucose level; and
an encryption controller programmed to;
provide authorization credentials to a patient monitor; and
encrypt information, including said glucose level, transmitted from said minimally invasive glucose reader to said patient monitor; and
said patient monitor in communication with said minimally invasive glucose reader;
the patient monitor comprising a processor programmed to;
operate as an oximeter;
operate as a glucometer when in communication with said minimally invasive glucose reader;
receive said authorization credentials;
determine, based on said authorization credentials, that said minimally invasive glucose reader is authorized to communicate with said patient monitor;
receive and unencrypt said information transmitted to said patient monitor; and
display said glucose level.

Abstract
In an embodiment, a patient monitor, such as a pulse oximeter, functions as a spot check glucometer when in communication with a blood glucose strip reader. In an embodiment, communications between the patient monitor and the strip reader may optionally be encrypted. Embodiments also include the strip reader housed in a dongle configured to mate with a sensor port of the pulse oximeter.

9. An encrypted source-identifying glucose strip reader configured to change an oximeter into a glucometer, said reader comprising:
-
a strip reader configured to accept samples on a strip and output a signal responsive to characteristics of said sample, said characteristics including a measure of glucose in said sample; a processor programmed to communicating with said strip reader to determine said measure of glucose from said sample and output data indicative of at least said measure; an encryption controller programmed to; provide authorization credentials to an oximeter configured to determine, based on the authorization credentials, that said reader is authorized to communicate with said oximeter, wherein said authorization credentials identify a source of said reader; receive said output data from said controller; encrypt said output data; and communicate, after encryption, said output data to said oximeter, wherein said oximeter is configured to modify its operation to present display indicia to a user of the oximeter, the display indicia responsive to said measure of said glucose in said sample; and a housing that houses said strip reader, said processor, and said encryption controller. - View Dependent Claims (10, 11, 12, 13, 14, 15)
