Abstract

A combination glucose measuring and insulin pumping device is described. The two major components, a glucose measuring module and an insulin pump, are held together by a quick attach and release mechanism. Communication between the glucose measuring module and the insulin pump is by a wireless modality. The glucose measuring module determines the glucose level in a sample, and wirelessly transmits the data to the insulin pump, where the data are stored in a memory, and are available for visual display on the insulin pump, and for incorporation into selection of appropriate protocols for the rate of insulin infusion by the pump into the patient.

Claims

1. A glucose sensor module, comprising:

an exterior glucose sensor module housing without a display, the exterior glucose sensor module housing including a strip port;

a glucose sensor strip connector coupled to the exterior glucose sensor module housing;

a microprocessor provided in the exterior glucose sensor module housing for receiving data from a glucose sensor strip via the connector and for determining data relating to a glucose value based on a sample on the glucose sensor strip;

a data communication module in signal communication with the microprocessor for receiving the data and transmitting the data from the glucose sensor module; and

a mechanical clasp including a lip shaped to permit removable attachment of the exterior glucose sensor module housing with a lip engaging portion of an insulin pump having a data port;

wherein when the mechanical clasp is removably attached with the lip engaging portion, the data communication module is aligned with the data port of the insulin pump to transfer data therebetween; and

further

wherein the microprocessor is activated to initiate one or more routines to determine the data related to the glucose value based on the sample on the glucose sensor strip when the microprocessor detects a presence of the glucose sensor strip in the strip port.

2. The glucose sensor module of claim 1 wherein the data communication module comprises one of an infrared transmitter or a receiver or a short range radio frequency transmitter and/or receiver.

11. The glucose sensor module of claim 1 wherein the mechanical clasp extends, via an extension portion, from the exterior glucose sensor module housing.

12. The glucose sensor module of claim 11 wherein at least a portion of the extension portion is secured to at least a portion of a housing of the insulin pump when the mechanical clasp is removably attached to the lip engaging portion of the insulin pump.

13. The glucose sensor module of claim 1 wherein the lip engaging portion of the insulin pump includes at least one alignment mechanism configured to prevent the mechanical clasp from sliding along the lip engaging portion when the mechanical clasp is removably attached to the lip engaging portion of the insulin pump.

4. A glucose sensor module, comprising:

an exterior glucose sensor module housing without a display, the exterior glucose sensor module housing including a glucose sensor strip connector and a data communication port;

at least one microprocessor for receiving data from a glucose sensor strip via the glucose sensor strip connector and for determining data relating to a glucose value based on a sample on the glucose sensor strip;

a wireless data transmission module communicating with the at least one microprocessor for receiving the data and wirelessly transmitting the data; and
