Intended Use

The Nelson Sentinel Series Basic Chlorine Sentinel is an instrument that is intended for use by hemodialysis professionals as an auxiliary device to provide continuous monitoring of Total chloramines plus ammoniated free chlorine) concentration. It is not intended to replace the primary method for monitoring total chlorine as part of the hemodialysis water treatment system. It functions completely independent of the water treatment system and does not come into direct contact with feed water used to prepare dialysate.

Device Story

The Nelson Sentinel Series Basic Chlorine Sentinel is an auxiliary monitoring system for hemodialysis water treatment. It uses a polarographic sensor with a polymeric membrane to detect dissolved total chlorine (chloramines and ammoniated free chlorine) in water samples taken downstream of the secondary carbon filter. The system includes a master control enclosure, a probe/tester enclosure, and a remote module for the nurse's station. It operates via a microcontroller that triggers visual (red/yellow/green LEDs) and audible alarms when chlorine concentrations exceed a 0.10 mg/L set-point or if system faults (e.g., probe failure, power loss, flood detection) occur. The device uses a peristaltic pump for automated sample delivery. It provides continuous monitoring to alert clinicians to potential chlorine breakthrough, allowing for timely intervention to prevent patient exposure to contaminated water. It does not record chlorine values but provides binary status outputs for alarm conditions.

Clinical Evidence

Bench testing only. No clinical data. Performance verified via linearity, precision, limit of blank/quantitation/detection, method comparison, peristaltic pump/tubing validation, free chlorine study, and 15-week calibration study.

Technological Characteristics

Polarographic sensor with polymeric membrane; peristaltic pump for sample delivery; PVC, stainless steel, and ABS plastic construction; 110-240 VAC power; backlit LCD display; continuous monitoring; non-networked; microcontroller-based; IEC 61010-1 and IEC 61326-1 compliant.

Indications for Use

Indicated for hemodialysis professionals to provide continuous monitoring of total chlorine (total chloramines plus ammoniated free chlorine) concentration in water treatment systems. Not for use as a primary monitoring method; does not contact feed water used for dialysate preparation.

Regulatory Classification

Identification

A water purification system for hemodialysis is a device that is intended for use with a hemodialysis system and that is intended to remove organic and inorganic substances and microbial contaminants from water used to dilute dialysate concentrate to form dialysate. This generic type of device may include a water softener, sediment filter, carbon filter, and water distillation system.

Special Controls

*Classification.* Class II (special controls). The device, when it is a water purification subsystem disinfectant, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.

The Basic Chlorine Sentinel detects dissolved chlorine by an auxiliary meter detection technology, self-monitors for maintenance-required conditions, loss of electrical power, as well as two other system conditions such as flooding and the status of RO shutdown alarm. The device chlorine monitoring probe is preferably placed after the second carbon filter, before the RO machine or at the beginning of the patient water treatment loop. The device has three components - a lockable master control enclosure, a lockable probe/tester enclosure, and the remote module installed in the patient area. A chlorine concentration equal to or above the set-point (default: 0.10mg/L) will activate the buzzers and the red CHLORINE alarm indicators for as long as the condition exists. The buzzers can only be muted for 3 minutes (then automatically reset) for as long as the condition exists. The yellow AUTO-TEST OK/CL DETECTED indication will latch. The AUTO-TEST/CL DETECTED indication can be deactivated after the event by pressing the blue RESET PUSHBUTTON on the front cover of the controller. A probe failure or the activation of one of the auxiliary input relays will activate the yellow MAINTENANCE needed indicators as well as the Buzzers which will remain activated as long as the condition exists. However, the buzzers can be muted by the key mute switch while the maintenance issue is being resolved. #### Indications for Use The Nelson Sentinel Series Basic Chlorine Sentinel is an instrument that is intended for use by hemodialysis professionals as an auxiliary device to provide continuous monitoring of Total Chlorine. (i.e. total chloramines plus ammoniated free chlorine) concentration. It is not intended to replace the primary method for monitoring total chlorine as part of the hemodialysis water {5}------------------------------------------------ treatment system. It functions completely independent of the water treatment system and does not come into direct contact with feed water used to prepare dialysate. #### Risk Analysis Method Nelson Sentinel Series Basic Chlorine Sentinel was assessed to determine risks to health associated with the use of the device, a risk analysis was conducted in accordance with ISO 14971: 2007, Medical devices - Application of risk management to medical devices. #### Substantial Equivalence The table below provides a detailed comparison of Nelson Sentinel Series Basic Chlorine Sentinel to the predicate and reference devices. {6}------------------------------------------------ ## Detailed Comparison of the Subject and Predicate Devices | ltem | Subject Device Nelson Sentinel Series Basic Chlorine Sentinel | Predicate Device UltraLow Total Chlorine and E-Z Chek Sensitive Total Chlorine Test Strips | Reference Device Hach CM130 Chlorine Monitor | Comparison | |-----------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Intended Use/Indications for Use | The Nelson Sentinel Series Basic Chlorine Sentinel is an instrument that is intended for use by hemodialysis professionals as an auxiliary device to provide continuous monitoring of Total Chlorine.
