The EasyStat 300 is designed for clinical laboratory use, making quantitative measurements of potassium (K+), ionized calcium (Ca++), and chloride (Cl-) in whole blood (arterial/venous) samples from Li-Heparinized Syringes. This Analyzer should only be used by trained technical laboratories to aid in the dagnosis and treatment of patients with electrolyte and/or acid-base disturbances. Potassium (K+) measurements are used to monitor electrolyte balance in the diagnosis and treatment of diseases conditions characterized by low or high blood potassium levels. Calcium (Ca++) (ionized) measurements are used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease and tetany (intermittent muscular contractions or spasms). Chloride (Cl-) measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis.

The EasyStat 300 is a system for use by health care professionalsto rapidly analyze venous and arterial whole blood samples in a clinical laboratory setting. The analyzer incorporates a Reagent Module containing the "calibrating" solutions A2, B2, and a "conditioning" solution C2. Calibrations are performed automatically or on-demand by the user to establish the "slope" of each sensor, used in the calculation of the patient sample. The analyzer employs "Ion Selective Electrode" (ISE) sensors for K*, Ca**, Cl¯. The EasyStat 300 uses 175µL of whole blood in the "Syringe" mode to analyze patient samples. The EasyStat 300 reports results for Potassium (K+), Calcium (Ca++), Chloride (Cl-). Additionally, it provides a number of calculated parameters based on the reported results and a number of input parameters as described in the Operator's Manual. Medica's EasyQC materials (REF 8315/8316/8317) are specifically formulated for the EasyStat 300. Medica requires the use of quality controls every day patient samples are analyzed and after any troubleshooting is performed, as instructed in the Operator's Manual, to validate the performance of the analyzer. The analyzer stores QC results and provides a statistical analysis of its performance using Levey-Jennings plots for the last 30 consecutive days. The Reagent Module (REF 8101) has a twelve-month shelf-life when stored at 4º-25ºC. The electrolyte sensors (K, Ca, Cl) have one-year shelf-life when stored at 4º-25ºC. Use-Life of the sensors is determined from their calibration profiles and from the reported results during the EasyQC analysis. Sensors are replaced by the operator as described in the Operator's Manual. An automatic calibration is performed after installation to qualify the new sensor(s) and the operator is instructed to use the EasyQC multi-level QC materials to validate the EasyStat 300 performance. The EasyStat 300 may be equipped with a Medica provided barcode scanner (REF 8420) via a USB port to automatically enter patient sample and EasyQC material information. Details are provided in the operator's Manual. To maintain the performance of the analyzer Medica provides a cleaning solution (REF 8305) and a troubleshooting kit (REF 8250). Their proper uses are described also in the operator's Manual.

The EasyStat 300 is designed for clinical laboratory use, making quantitative measurements of pO2 (partial pressure of oxygen), pCO2 (partial pressure of carbon dioxide), and pH (hydrogen ion activity) in whole blood (arterial/venous) samples from Li-Heparinized Syringes or Capillary Tubes. This Analyzer should only be used by trained technicians in clinical laboratories to aid in the diagnosis and treatment of patients with blood gas and/or acid-base disturbances.

The EasyStat 300 is a system for use by health care professionals to rapidly analyze whole blood samples. The analyzer incorporates a Reagent Module containing the "calibrating" solutions A2, B2, and a "conditioning" solution C2, which is also use a calibrant for the Oxygen sensor. Calibrations are performed automatically or on-demand by the user to establish the "slope" of each sensor used in the calculation of the patient sample. The EasyStat 300 uses 175μL of whole blood in the "Syringe" mode and 100μL of whole blood in the "Capillary" mode to analyze patient samples. The EasyStat 300 reports results for blood Gases (PCO2, PO2), and pH. Additionally, it provides a number of calculated parameters based on the reported results and a number of input parameters as described in the Operator's Manual. The EasyStat 300 is a microprocessor-controlled device with a touch sensitive screen that guides the operator through the different menu options and proper operation. It also incorporates a thermal printer to record all reported results and patient information as described in the Operator's Manual. The device software has incorporated routines to assist the end-user with maintenance, cleaning, and troubleshooting activities also outlined in the manual. The incorporated USB port may be used to download data and also to update the software version based on detailed instructions by Medica Corporation. The blood gas and pH sensors require calibration and cleaning after a predefined number of samples are analyzed as described in the Operator's Manual. The pH and PCO2 sensors are based on potentiometric sensor design, generating a small voltage that is dependent on the concentrations of these analytes in the patient sample. The PO2 sensor is based on amperometric sensor design that generates a small current that is dependent on the concentration of oxygen in the patient sample. Medica's EasyQC materials are specifically formulated for the EasyStat 300. The EasyStat 300 may be equipped with a Medica provided barcode scanner via a USB port to automatically enter patient sample and EasyQC material info. To maintain the performance of the analyzer Medica provides a cleaning solution and a troubleshooting kit.

The Catalys Precision Laser System ("Catalys System" or "System") is an ophthalmic surgical laser system indicated for use in cataract surgery to create a precise anterior capsulotomy and/or to effect lens fragmentation, thus facilitating efficient lens removal. The System also creates single plane and multi-plane arc cuts/incisions in the cornea, each of which may be performed either individually or consecutively during the same procedure. The System employs femtosecond ("FS") laser technology with integrated Optical Coherence Tomography ("OCT"), all of which are controlled and monitored by dedicated electronics. The System utilizes a common optical path for the OCT and femtosecond treatment laser (including the three-dimensional scanner and Liquid Optics "[patient] Interface). As such, the beams are intrinsically co-registered and provide for precise overlap between imaging and treatment beams. Ocular surfaces recognized by the system software include anatomy within the anterior chamber, such as the anterior and posterior corneal surfaces and the anterior and posterior surfaces of the crystalline lens. Detailed axial or sagittal cross-sectional views are available via OCT, to demarcate proposed incisions versus adjacent ocular structures (for example, iris, pupil and limbus).
