Receptacle unit for solutions, in particular solutions for calibration of sensors for measuring physiologically relevant parameters
First Claim
1. A receptacle for solutions used to calibrate sensors for measurement of physiologically relevant parameters, comprising:
- a base body;
an envelope of flexible material attached to a front surface of the base body;
a plurality of chambers capable of holding a calibration solution, formed between the base body and the envelope;
an outlet orifice formed in each one of the plurality of chambers;
a sealing element for sealing the outlet orifice;
a sample channel in fluid communication with the outlet orifice of each chamber for receiving the calibration solutions after the sealing elements are opened;
sensors positioned in the sample channel which are calibrated upon contact with the calibration solutions; and
contacts on an external portion of the receptacle, the contacts for electrically connecting the sensors to an outside connection.

Abstract
A disposable receptacle unit for solutions is described, in particular for solutions used in calibrating sensors for measurement of physiologically relevant parameters. The receptacle is a disposable blister pack for a single use that includes several chambers to hold solutions. Each chamber is connected to a sample channel by an outlet channel sealed by a sealing element. The sensors for measurement of physiological parameters are preferably part of the receptacle unit. To calibrate the sensors, the calibration solutions in the chambers are metered into the sample channel after opening the corresponding sealing elements. After the treatment, the receptacle unit is discarded together with the sensors.

14. A method for calibrating sensors for measurement of physiologically relevant parameters, comprising the steps of:
-
inserting a receptacle having a plurality of chambers containing a metered amount of calibrating solutions in an analyzer;
puncturing a sealing element of a selected one of the chambers with a ram portion of the analyzer;
flowing the solution in the selected chamber into a central sample channel of the receptacle;
measuring values of the solution with sensors located in the central sample channel; and
reporting values measured by the sensors to the analyzer through electrical connections formed in the receptacle.
