# Description:

## System

The DS-5300 Patient Monitor System is meant to acquire and monitor physiological signals from patients located within a healthcare facility. The system is designed to be used in an ICU, CCU, OR, ER, or Recovery areas of a hospital or clinic. Patient ages from neonates to adults can all be monitored. Waveforms, numeric, and trend data from these patients are available to the clinician on the system’s display or it may be printed on the system’s recorder.

The basic system consists of the main control unit, the display unit and the input box connected to the main unit via fiber optic cable to reduce electrical artifact and noise.

The main body of the system can be remotely located from the display unit and input box for increased flexibility. Small, lightweight, but powerful in its application of technology, the DS-5300 patient monitoring system is flexible and easy to use. Incorporation of high speed RISC (reduced instruction set computing) microprocessors, a 9.4 inch TFT color LCD display and a high quality, analog touch screen has made the DS-5300 a unique and versatile patient monitor. The die cast aluminum body eliminates the need for a cooling fan and provides a light, strong body. Use of low power, high speed, flash memory allows for easy upgradeability through a standard PCMCIA compatible IC card.

Physiological parameters are monitored through the use of flexible parameter modules that are easily inserted or removed from the input box.

## Comparison to Predicate Device

In summary, the DS-5300 system is an improved version of the DS-3300 utilizing the latest technology and incorporating a color display. Changes to the system include a single multi-parameter module that replaces several of the individual modules used in the DS-3300. A change is processor technology required software changes but all algorithms are based on Fukuda Denshi algorithms that have been in use and are part of the standard Fukuda Denshi software library. The majority of the changes can be

summarized as display oriented or minor changes to alarm limit adjustment ranges.

## Technological Characteristics

The DS-5300 incorporates high speed RISC (reduced instruction set computing) microprocessors as compared to the CISC (complex instruction set computing) employed in the predicate device. The DS-5300 utilizes 9.4 inch TFT color LCD display with a high quality, analog touch screen as compared to the 12 inch monochrome CRT with a similar touch screen used in the predicate device. Physiological information is acquired through modular inputs in the same manner as the predicate device. A PCMCIA card interface provides a means to temporarily store data or to update the system’s flash memory.

The pulse oximetry design is licensed from Nellcor Puritan Bennett and is similar to the Nellcor design used in the predicate device.

These technological differences do not affect the safety or efficacy of the device. Any safety issues that may be raised by a software controlled medical device are the same issues already addressed by the predicate device and are addressed in the systems hazard analysis and in the system validation.

## Testing:

Laboratory testing was conducted to validate and verify that the Fukuda Denshi model DS-5300 Patient Monitor met all design specifications and was substantially equivalent to the FUKUDA DENSHI model DS-3300. This testing consisted of all environmental testing identified in the FDA’s DCRND November 1993 “Reviewer Guidance Document for Premarket notification Submissions” Draft Guidance Document. Additional testing was performed to demonstrate compliance with the ANSI/AAMI standards ES1-1993, “Safe current limits for electromedical apparatus”; EC11-1991, "Diagnostic electrocardiographic devices”; and EC13-1992, “Cardiac monitors, heart rate meters, and alarms.” Finally, a hazard analysis of the system and its software was performed and testing was conducted to validate the systems overall operation.

Testing of the non-invasive blood pressure portion of the system was conducted according to the requirements outlined in the ANSI/AAMI standards SP10-1992, “Electronic or automated sphygmomanometers.” The results of this testing is presented in tabular and graphic format in the appendix.

Testing of the pulse oximetry portion of the system was conducted according to Nellcor Puritan Bennett’s testing protocol. The results of this testing is presented in tabular and graphic format in the appendix. The results of this testing is presented in tabular and graphic format in the appendix.

Testing of the arrhythmia and ST Level portions of the system were conducted according to AAMI Recommended Practice ECAR-1987, “Recommended Practice for Testing and Reporting Performance Results of Ventricular Arrhythmia Detection Algorithms. The results of this testing is presented in tabular format in the appendix.

Although the device is neither life supporting nor life sustaining, diagnostic information derived from the use of the device and alarms generated by the device may be critical to the proper management of the patient.

So, the areas of risk for this device are the same as other devices in this class, and are the following:

- Electrical shock
Excessive electrical chassis leakage current can disturb the normal electrophysiology of the heart, and possibly leading to the onset of cardiac arrhythmias.

- Misdiagnosis
- Inadequate design of the signal processing and measurement circuitry or program can lead to generation of inaccurate diagnostic data. If inaccurate diagnostic data are used in managing the patient, the physician may prescribe a course of treatment that places the patient at risk unnecessarily.
- Inadequate design of the device's software, used to make various measurements, can lead to generation of inaccurate diagnostic data. If inaccurate diagnostic data are used in managing the patient, the physician may prescribe a course of treatment that places the patient at risk unnecessarily.
- Inadequate design of the systems ability to alert the users through audible and visual indicators, can lead to user mistrust and/or inadequate response to the patient’s condition. If an inadequate response to the patient’s condition should occur the patient may unnecessarily be placed at risk.

The design of the DS-5300 has taken into account all the above. The device is designed to meet UL 601, CSA 22.2 and AAMI standards for electrical safety for medical equipment to prevent the possibility of excessive electrical leakage current to the patient.
