The Multi-Parameter Mobile CareGuide 4100 is a noninvasive optical sensor that determines two separate medical parameters and reports them out for display to the user in real-time. Light sources in the sensor illuminate the skin with near infrared (NIR) light passes through the skin and fat with only some loss to be primarily absorbed by small blood vessels in the muscle tissue. Light which is not absorbed is scattered back and analyzed by the spectroscopic detector, also contained in the sensor. The microprocessor in the sensor converts the reflected light to an absorbance spectrum which is then analyzed by two separate algorithms, also stored in the sensor's microprocessor. The two algorithms calculate muscle oxygen saturation (Sm22), and muscle pH (pHm). The sensor is attached to the patient using the CareGuide Disposable. One Disposable is used per patient, but the CareGuide Sensor is reusable. To use, the adhesive liner is removed from the Disposable and, with the sensor clipped into the Disposable, is adhered to the patient's skin over either the deltoid, calf or thigh muscle. When the sensor is first placed on the patient, software checks to make sure the LEDs are functioning properly and then the sensor automatically performs an optimization routine which sets up the spectral data collection parameters for the individual patient. Once conditions are established the sensor begins collecting spectra and reporting parameter values. The Multi-Parameter Mobile CareGuide 4100 measures and provides for output of SmO2 and pHm data. The Multi-Parameter Mobile CareGuide 4100 communicates with either a 3ª party display or monitoring device, or RMI-supplied tablet, which is compliant with the Mobile CareGuide communications protocol. Sm02 and pHm values suitable for display and trending are sent via the Mobile CareGuide communications protocol to the display device as well as error information and device states.

The Multi-Parameter Mobile CareGuide 3100 Oximeter with Tablet reusable sensor contains the optical and electronic elements necessary to collect spectra from skin, fat and muscle. The sensor has a 3m long cord with a USB connection to the Android tablet. The sensor is identical to the predicate (K130079) Multi-parameter Mobile CareGuide 3100 Oximeter. The Multi-Parameter Mobile CareGuide 3100 Oximeter with Tablet uses the same disposable element as the Multi-Parameter Mobile CareGuide 3100 Oximeter, a disposable sleeve that isolates the sensor optical elements from the patient's skin.

The Terumo Khuri™ Myocardial pH Monitoring System is intended for use in monitoring local tissue pH and temperature, typically during procedures in which specific tissues may be subjected to conditions which may result in ischemia, such as the myocardium, during cardiac operations. These parameters are displayed at 37°C corrected value. For documentation purposes, the integral printer provides a hard copy of displayed parameter.

The Terumo Khuri™ Myocardial pH Monitoring System (Khuri MpH system) is an AC-powered (battery support for memory retention), microprocessor-based device consisting of a monitor, sensor and interface module'. The myocardial pH sensor will consist of two pH measurement probe electrodes and a reference electrode for the purpose of monitoring continuous myocardial tissue pH and temperature during cardiac surgery. The system uses electrochemical technology to measure the hydrogen ion content of the myocardial tissue, and report that information via electrical cable back to the monitor, where a processing unit coverts the electrical signal into pH units for display on the monitor. The Khuri MpH system Monitor consists of a single board computer and a dedicated circuit that contains digital circuitry to interface with the interface module that connects to the sensor (pH electrodes and reference probe). The system will have an LCD flat touch screen display that will control the mode and operation of the monitor. The monitor will have a printer that will enable the user to print out case results. The monitor will be able to be mounted on a vertical pole or rest on a flat surface. Each Khuri MpH system Sensor consists of two pH electrodes and one reference electrode. The pH electrodes are designed with a pointed tip for insertion into tissue with minimal resistance. The pH electrode consists of a closed end glass tube made from pH sensitive glass. The tube is filled with a phosphate based internal buffering solution in which a silver wire coated with silver chloride is inserted. The wire is attached to a cable, which is encased in an electrically shielded sheath and attaches to the monitor. The tip of the glass is pointed to allow easy insertion in to the myocardial tissue during use. The thermistor is a metal oxide ceramic tip. which is imbedded in the plastic surrounding the rear of the glass tube. A reference electrode is used to complete the circuit. The reference electrode consists of an Ag/AgCl wire inserted into a plastic tube of KCI electrolyte solution. The front end of the tube is tapered to a small diameter to facilitate insertion into the tissue (usually near the sternum) during use. It is plugged with a semi-permeable material that prevents bulk leakage of fluid but maintains electrical contact with the patient during pH measurement. The wire protrudes from the sealed back end of the tube and is attached to a cable, which connects to the monitor. The analog voltage signal from the sensor is fed into an interface module that amplifies and conditions the analog signal to remove any interfering noise. The analog signal is then converted into digital information in the A to D converter. This digital signal is then fed from the interface module to the monitor where a conversion algorithm, in the monitor, is used to convert digital information into pH units. The values are then displayed on the monitor screen.

The modified SensiCath Sensor, when used as part of the Point-of-Care Blood gas Monitor System is intended to provide on-demand arterial blood gas monitoring in the operating room and at the bedside for critically ill patients requiring an arterial pressure monitoring line. The ABG information is available to the attending qualified medical professional on demand and within approximately 60 seconds of the time the sample cycle was initiated. The intended use of the modified SensiCath Sensor is the same as the predicate SensiCath Sensor.

It is the intention of Optical Sensors Incorporated (OSI) and Marquette Electronics Incorporated (MEI) to introduce into commercial distribution a modification to the SensiCath Arterial Blood Gas Sensor. The modified sensor has a longer useful life and allows a greater number of ABG measurements. The modified sensor is substantially equivalent to the SensiCath Sensor presented in the SensiCath™ Point-of-Care Blood Gas Monitor System which received Food and Drug Administration (FDA) clearance to market, 510(k) K95 1094. The modified SensiCath Sensor operates with the SensiCath Point-of-Care Blood Gas Monitor System, just as the predicate SensiCath Sensor. As with the predicate sensor, the modified SensiCath Sensor measures blood gas parameters of partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2) and the blood's hydrogen ion concentration, (pH). The modified SensiCath Sensor is manufactured and sterilized by Optical Sensors Incorporated, as is the predicate SensiCath Sensor.
