Portable Electrolyte Analyser ‘STAX-5 inspire’

Portable Electrolyte Analyser ‘STAX-5 inspire’

Techno Medica Co., Ltd.

Immediate and Precise Electrolyte Analysis for
Blood Test and Hydroponics   

STAX-5, a point of care electrolyte analyzer is intended for in vitro diagnostic use by health care professionals. It conducts the quantitative determination of cNa+, cK+, cCl-, cCa2+, cMg2+, pH, pCO2 (partial pressure of CO2), Hct (hematocrit) by using disposal sensor card with only 10 micro liters blood. Operation is simple enough to get the analysis results with three steps. You can get reliable result in sixty to one hundred eighty seconds (depends on the type of sensor card) with printed report, and also possible to use at outdoors by battery-powered.

Beside medical use, STAX-5 is potentially useful for the measurement and quality control of fertilizer
concentration in hydroponics in the agricultural field.

Technology Data

Possible applications

The world-first electrolyte analyser for Point-of-Care Testing (POCT)

  • Symptoms of dizziness, seizures, etc. and various symptoms with out-of-conscious condition, such as heat stroke, sunstroke and dehydration, can be easily checked in the field.
  • Clinical examination items, such as electrolyte abnormalities, acid-base equilibrium abnormalities, etc. are possible to measure in the field.
  • The concentration of the dialysate component and selection of the drip species are possible to confirm.

In the following applications, STAX-5 can help improvement of the appropriateness and safety of treatment and can reduce medical costs eventually.

STAX-5 can reduce the physical burden of the patient by easily measurable in fingertip puncture blood and earlobe blood instead of clinical tests such as electrolyte items that have been carried out in general intravenous blood collection.

Since doctors can immediately confirm efficacy of drugs and infusions by measuring in the ward by STAX-5, the it can reduce the risks of errors in blood sample transport, the temporal loss of waiting for the results of clinical tests, and the delay in the reflection of the analysis results to the patient treatment.

Since STAX-5 is relatively low implementation cost and simple operation, it is easy to introduce for the facilities that have managed dialysate fluid only by osmotic pressure and electrical conductivity. By performing the electrolyte measurement in STAX-5, it is possible to manage dialysate fluid more precisely.

STAX-5 can also be used for the measurement and quality control of fertilizer concentration in hydroponics in the agricultural field.

Competitive advantage

STAX-5 is the world-first Mg+ POCT analyzer which also can analyze Na+, K+, Cl-, pH, pCO2, Mg2+ and Ca2+ in 10 microliters only of blood, with high precision, easily and rapidly without pre-processing. STAX-5 is easy to analyze by just inserting a patented disposal sensor card that can be used by storage for two months at the room temperature, and for one year at refrigerator.
STAX-5 can reduce the physical burden of the patient by easily measuring with small-volume blood.
Since STAX-5 is a hand-held type, and equipped with battery-powered features, built-in printers, touch panel color LCD displays, etc., it can be used even in outdoors, such as at the site of a disaster.
