Intended Use

The IRMA Blood Analysis System is intended for professional use in those settings where blood gases (pCO2 and pO2), pH, Na+, K+, iCa++ and Hct in whole blood are performed such as the clinical laboratory or the patient bedside. The system may utilize either a single-use or a multi-use cartridge for these measurements. The pH, pCO2, pO2 measurements, and their associated calculated values are used to assess acid-base status and state of oxygenation. Common causes of acid-base abnormalities, drugs and poisons, and fluid imbalance. The electrolyte measurements (Na+, K+) are used to assess hydrational status, aid in the diagnosis of respiratory and metabolic acid-balance, and prevention of cardiac arrhythmia. Conditions which utilize these measurements for diagnosis are nutrition, diarrhea, ketoacidosis, alcoholism and other toxicities. The measurement of ionized calcium is used to assess disease states such as thyroid abnormalities, renal failure or transplant, and to monitor dialysis patients. The measurement of hematocrit is used to assess anemia, blood loss such as in an accident or during surgical procedures, and polycythemia. These indications for use of the IRMA Blood Analysis System which utilizes the multiuse cartridge are identical to those of the IRMA Blood Analysis System which utilizes the single-use cartridge. The System will now offer the user an option to choose which cartridge platform best fits their needs either the single-use or multi-use cartridge. Both platforms offer the following sensors: blood gases (pCO2 and pO2), pH, sodium, potassium, ionized calcium, and hematocrit. Similar to the single-use cartridge, the sensor arrays of the multi-use cartridge will also be packaged in various combinations.

Device Story

IRMA Blood Analysis System performs point-of-care or clinical laboratory whole blood analysis; utilizes interchangeable single-use or multi-use cartridges containing sensor arrays; measures pCO2, pO2, pH, Na+, K+, iCa++, and Hct; provides calculated values for acid-base and oxygenation assessment; operated by healthcare professionals; output used for diagnosis of metabolic/respiratory conditions, electrolyte imbalances, and monitoring of dialysis or surgical patients; aids clinical decision-making regarding patient acid-base status, hydration, and anemia management.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing and performance comparison between the multi-use cartridge platform and the predicate single-use cartridge platform.

Technological Characteristics

System utilizes electrochemical sensor arrays for blood gas, electrolyte, and hematocrit measurement. Features interchangeable cartridge platforms (single-use vs. multi-use). Connectivity and software details not specified. Device is intended for professional use in clinical or bedside environments.

Indications for Use

Indicated for professional use in clinical laboratory or bedside settings to measure blood gases (pCO2, pO2), pH, electrolytes (Na+, K+), ionized calcium (iCa++), and hematocrit (Hct) in whole blood. Used to assess acid-base status, oxygenation, hydrational status, metabolic balance, thyroid/renal function, and anemia/blood loss.

Regulatory Classification

Identification

A blood gases (PCO2 , PO2 ) and blood pH test system is a device intended to measure certain gases in blood, serum, plasma or pH of blood, serum, and plasma. Measurements of blood gases (PCO2 , PO2 ) and blood pH are used in the diagnosis and treatment of life-threatening acid-base disturbances.

Dear Mr. Boeh:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
