Control solution packets and methods for calibrating bodily fluid sampling devices

Abstract

A control solution packet for calibrating a bodily fluid sampling device includes a container, a control solution pressurized within the container, and a membrane for covering and sealing the container. The control solution can be pressurized before or during calibration so as to ensure the appropriate amount of control solution is delivered to the bodily fluid sampling device. The control solution is manufactured to have a viscosity that controls delivery of the control solution to the device. The membrane is permeable by a piercing device of the bodily fluid sampling device and seals around the piercing device during calibration. In another aspect, the container is in the form of a capsule or dosing attachment that contains the control solution along with a sponge-like material.

AI Technical Summary

Benefits of technology

[0008]The present invention relates to an improved control solution packet for calibrating a bodily fluid sampling system includes a device and a disposable test strip in which the control solution packet provides easy and accurate test results.

Problems solved by technology

Inaccurate calibration readings may result when the user fails to follow the proper testing procedures.

In order to utilize a control solution, the user is therefore required to perform a plurality of steps, any of which can lead to the introduction of errors in the control solution testing, thereby potentially leading to erroneous results.

Moreover, by not calibrating the device in the manner in which it is used, problems associated with the operation of the device, such as contamination, may remain undetected.
