Intended Use
The Nihon Kohden CSM-1901 Bedside Monitor is intended to monitor, display and record physiological data to provide cardiac and vital signs monitoring within a medical facility. The device is intended to produce a visual record of the electrical signal produced by the heart and monitor the electrocardiogram to generate visible alarms when an arrhythmia exists. The device is also intended to monitor heart rate, blood oxygen saturation (SpO2), noninvasive blood pressure (NIBP), invasive blood pressure (IBP), body temperature, BIS, cardiac output (CO), oxygen concentration (FiO2), carbon dioxide concentration (CO2), EtCO2, respiratory rate, inspired and expired anesthetic agents and anesthetic gases including N20, halothane, enflurane, enflurane and desflurane. The device also displays patient data from external devices such as ventilators, TOF monitors, and EEG measuring unit. The device may generate and audible and/or visual alarm when a measured rate falls outside preset limits. The device will be available for use by trained medical facility on all patient populations, including adult, neonate, infant, child, and adolescent subgroups.
Device Description
The Bedside monitor CSM-1901 is a device which continuously monitors physiological information of a patient and is used in an operation room, a recovery room, general wards, ICU, CCU, HCU, NICU and an emergency room. This bedside monitor is placed near the patient and is intended to display patient's vital signs. This device can also be connected to other external patient monitoring devices. In addition, this device can communicate patient's data to a central monitoring station via network to monitor multiple patients.

K082785

No
The document describes a standard bedside monitor for physiological data and does not mention any AI or ML capabilities.

No
The device is intended for monitoring, display, and recording of physiological data, not for treating conditions or diseases.

Yes

The device is intended to "monitor, display and record physiological data" and to "monitor the electrocardiogram to generate visible alarms when an arrhythmia exists." While it monitors and displays, the explicit mention of generating alarms for arrhythmias indicates it provides information that can be used to make a diagnosis or to alert practitioners to a condition that warrants further diagnostic investigation.

No

The device description explicitly states it is a "Bedside monitor CSM-1901" which is placed near the patient and displays vital signs. This indicates a physical hardware component, not a software-only device. The performance studies also mention testing to compliance standards for electrical and electromagnetic safety, further suggesting a hardware device.

Based on the provided information, the Nihon Kohden CSM-1901 Bedside Monitor is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body. The intended use and device description clearly state that this device monitors physiological data directly from the patient (ECG, heart rate, SpO2, NIBP, IBP, temperature, etc.). It does not analyze blood, urine, tissue, or other bodily fluids or substances in vitro (outside the body).
  • The device's function is real-time physiological monitoring. It measures and displays vital signs and other physiological parameters as they occur in the patient. This is distinct from the analysis of specimens in a laboratory setting, which is the hallmark of IVD devices.

Therefore, the Nihon Kohden CSM-1901 Bedside Monitor falls under the category of patient monitoring devices, not IVD devices.
