Battery case

<cNa+> Ion selective electrode liquid membrane typeChemical substances which selectively react with sodium ion are
captured by polyvinyl chloride membrane with plasticizer. The
potential difference generated when standardized calibrator andsample contact membrane in order are measured. Sodium ions
(cNa+) are calculated based on this potential difference of calibrator
and sample.
<cK+> Ion selective electrode liquid membrane typeChemical substances which selectively react with potassium ion
are captured by polyvinyl chloride membrane with plasticizer. The
potential difference generated when standardized calibrator andsample contact membrane in order are measured. Potassium ions(cK+) are calculated based on this potential difference of calibratorand sample.

Dimensions: 95W x 215D x 86.5H mm
Weight: About 850g (without battery)(2) Sensor Card
Calibration packSample inlet cover<cCl-> Ion selective electrode liquid membrane typeChemical substances which selectively react with chlorine ion are
captured by polyvinyl chloride membrane with plasticizer. The
potential difference generated when standardized calibrator andsample contact membrane in order are measured. Chlorine ions(cCl-) are calculated based on this potential difference of calibrator
and sample.

Sensor board<cCa2+> Ion selective electrode liquid membrane typeChemical substances which selectively react with calcium ion arecaptured by polyvinyl chloride membrane with plasticizer. The
potential difference generated when standardized calibrator andsample contact membrane in order are measured. Calcium ions(cCa2+) are calculated based on this potential difference ofcalibrator and sample.

Sample inlet<cMg2+> Ion selective electrode liquid membrane typeChemical substances which selectively react with magnesium ion
are captured by polyvinyl chloride membrane with plasticizer. The
potential difference generated when standardized calibrator andsample contact membrane in order are measured. Magnesiumions (cMg2+) are calculated based on this potential difference ofcalibrator and sample.

✓Chemical substances which selectively react with hydrogen ion(H+) are captured by polyvinyl chloride membrane with plasticizer.
The potential difference generated when standardized calibrator
and sample contact membrane in order are measured. pH are
calculated based on this potential difference of calibrator andsample.

✓✓✓<PCO2> Arranged Severinghaus type electrode
Arranged Severinghaus type electrode which includes Redox
reactive layer including the base electrode reacting with hydrogenion (H+), spreading layer, and gas transmission layer contact withstandardized calibrator and sample to measure the potential
difference. Partial pressure of carbon dioxide is calculated based on
this potential difference of calibrator and samples.

Do not measure samples except blood (whole blood,serum, plasma), dialysate, urine and Pinal fluid.
Perform quality control if necessary.
There is a case difficult to isolate problem caused bysample, instrument or sensor card. Re-measure sample
when abnormal measurement result is delivered.
Contact TechnoMedica or our local representative wheninsoluble trouble occurred.

Storage and Expiry
1. Storage<Instrument>
Storage environment: Not specified
Transportation temperature: -10 – 60 Celsius
Do not leave the instrument in direct sunlight.
Operation environment: Temperature 10 – 35 Celsius, Humidity 10– 85% (No condensation)<Hct> Electric conductivity electrode
Standardized calibrator and sample are contacted the surface ofelectric conductivity electrode to measure the alternative current
impedance. Hematocrits are calculated based on this impedance.

<Sensor card>
Storage temperature: 2 – 30 Celsius, Not frozen
Operation environment: 15 – 30 Celsius

Intended Use
STAX-5 Inspire, a point of care electrolyte analyzer is intended for invitro diagnostic use by health care professionals for the quantitative
determination of cNa+,cK+,cCl-,cCa2+,cMg2+,pH, pCO2,Hct withusing disposable sensor card.

2. Life time, expiration date
<Instrument>
Durable year: 4years when the instrument is used underappropriate operation temperature, storage environment.

Direction for use
Ensure to read operation manual before operate the instrument.
1. Press power button.
2. Introduce a sample to sample inlet and close the sample
cover.
3. Insert the sensor card into the card inlet until a beep alarmsound. Measurement starts automatically.
4. Test results will be displayed after approx. 1minute for sensor
card E1, approx. 3minutes for sensor card E2 and E3.
5. Remove the sensor card from the instrument. Waste the usedsensor card as medical waste in follow the law.

Expiration date: Refer to package

CautionRead the following precautions carefully before performing above
maintenance✓
Wipe instrument softly by tissue paper or absorbent cotton
soaked by water or detergent. Do not use alcohol, acetone
and other solvents to prevent the instrument’s coating isremoved.
✓Ensure to use brand-new batteries.

MaintenancePerform the following maintenances if necessary(a) Clean instrument’s surface(b) Clean sensor card inlet of the instrument© Disinfect instrument(D) Perform daily quality control(E) Replace batteries

1. Important precautions✓
Ensure to read operation manual to operate the instrument
appropriately✓
Operational temperature for sensor card is 15-30 Celsius. In
case sensor card is kept in refrigerator, leave it more than
1hour in room temperature.
✓Insert sensor card into the instrument within 5minutes after
applying blood to prevent the blood is coagulated.
✓Do not hit or push sensor board and calibration pack.
✓Do not insert the sensor card that blood or other liquids areattached.
