Mlcoch DEVICE NAME: Name: Blood Warmer Proprietary Model: PRISMAFLO II Classification: 2 Product Code: KOC Regulation: Gastroenterology - Urology Devices (21CFR876.5820) ## PREDICATE DEVICES: Stihler Electronic GmbH, Blood Warmer Model PRISMAFLO - K020103 Barkey GmbH + Co. KG, Blood Warmer Model Prismacomfort-K071909 ## DESCRIPTION: The PRISMAFLO II is a modified version of the PRISMAFLO covered by K020103. The PRISMAFLO uses water in the heat transfer process. PRISMAFLO II is the same as PRISMAFLO except it is water free. The PRISMAFLO II dialysis fluid and blood warmer is substantially equivalent in safety and effectiveness to the legally marketed (predicate) Barkey Prismacomfort 510(K) Number K071909. The PRISMAFLO II blood warmer is used to warm the return blood flow line in order to replace heat lost to the atmosphere and effluent flow during a Prismaflex or PRISMA treatment. The PRISMAFLO II blood warmer consists of one control unit and one sleeve warmer. The control unit (Stihler PRISMAFLO II) controls the sleeve warmer and displays alarm and status messages. {1}------------------------------------------------ The PRISMAFLO II blood warmer warns the returning blood flow line by means of a silicon tube heat exchanger which covers the blood return flow line of the Gambro Prismaflex or Prisma system completely. The heat is transferred by the contact of the resistance heating system to the inscried blood return line. The complete enclosure of the returning blood flow line to be warmed ensures that there are no temperature losses to the surroundings. The warmth produced by the sleeve warmer is therefore transferred to the return blood flow at maximum efficiency. The sleeve warmer is powered with 22 VDC which is derived from 115 VAC (or where required 230 VAC). 50/60 Hz power supply and is controlled by an on-off switch on the front panel of the control unit Stihler PRISMAFLO II. Above the on-off switch is a display temperature monitor showing actual and set temperature. The temperature of the sleeve warmer and other performance characteristics of the sleeve warmer are controlled electronically, visual and audible alarms as well as cut-offs are hardware realized. Like the blood warmer Barkey Prismacomfort, the sleeve warmer PRISMAFLO II is constructed as a slotted enclosed silicon tube, which can completely enclose inserted blood return flow lines of up to 7.00 mm diameter. The PRISMAFLO II woighs approx 3.9 kg and is equipped with a holder at the rear side of the control unit, which allows mounting on hemodialysis system Gambro Prismatlex and Prisma system. Both products, the PRISMAFLO II and the Barkev Prismacomfort use sleeve warmers made of silicon. The flexibility of this material ensures a nearly complete enclosure of the blood return flow line on Gambro Prismallex and Prisma system. Only the water free operation of the PRISMAFLO II differs to the PRISMAFLO. ## INTENDED USE: The PRISMAFLO II is for warming dialysis fluid and returning blood flow. Federal law restricts this device to sale by or on the order of a physician. It is intended to be used only by appropriately trained and qualified healthcare professionals and scrvicing staff in clinical environments. ## SUMMARY OF NONCLINICAL TESTS AND DESIGN CONTROL ACTIVITIES: The PRISMAFLO II blood warmer complies with the safety standards below and is therefore safe for the intended use. The device has been thoroughly tested through validation and verification of specifications. Verification of compliance with the following mandatory and voluntary standards has been made: - ◆ DIN EN 60601-1 - DIN EN60601-1-2 � - UL 2601-1/10.97 � - . CAN/CSA-C22.2 No. 601.1-M90 - ASTM F 2172-02 (USA Standard for Blood and Fluid Warmers) . {2}------------------------------------------------ In order to verify effective performance of the Stihler PRISMAFLO II blood warmer in support of substantial equivalence, the following tests were carried out successfully: - Verify the ability of the system to prevent cooling down of blood return lines on Gambro Prismaflex CRRT system. - Verify the ability of the system to protect the patient and to detect and alarm at unsafe operating conditions. This control activity shows that there are no new questions of safety and effectiveness for the PRISMAFLO II blood warmer as compared to the predicate devices. ## CONCLUSION: The PRISMAFLO II blood warmer is substantially equivalent to the Barkey Prismacomfort, Both systems have the same intended use and are capable of heating blood return flow line on Gambro Prismaflex system. Both systems are the same according to the specifications of the device. Both use a water free heat reference to initiate the heat transfer process. The PRISMAFLO II is the same as the PRISMAFLO made by Stihler cxccpt for the water free operation. The water free modification is safe and effective per the controlled design process and equivalence to the predicate device.
