|
| • Blood Pressure Transducer |
| • Cortical Electrode (FDA Code: GYC / 882.1310) A cortical electrode is an electrode which is temporarily placed on the surface of the brain for stimulating the brain or recording the brain's electrical activity. |
| • Cutaneous Electrode (FDA Code: GXY / 882.1320) A cutaneous electrode is an electrode that is applied directly to a patient's skin either to record physiological signals (e.g., the electroencephalogram) or to apply electrical stimulation. |
| • Differential Gas Pressure Transducer (FDA Code: BYR / 868.2875) A differential pressure transducer is a two-chambered device intended for medical purposes that is often used during pulmonary function testing. It generates an electrical signal for subsequent display or processing that is proportional to the difference in gas pressures in the two chambers. |
| • Electroconductive Media (FDA Code: GYB / 882.1275) Electroconductive media are the conductive creams or gels used with external electrodes to reduce the impedance (resistance to alternating current) of the contact between the electrode surface and the skin. |
| • Electroencephalograph Electrode/Lead Tester (FDA Code: GYA / 882.1410) An electroencephalograph electrode/lead tester is a device used for testing the impedance (resistance to alternating current) of the electrode and lead system of an electroencephalograph to assure that an adequate contact is made between the electrode and the skin. |
| • Electroencephalographs (FDA Code: GWQ / 882.1400) An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head. |
| • Nasopharyngeal Electrodes (FDA Code: GZK / 882.1340) A nasopharyngeal electrode is an electrode which is temporarily placed in the nasopharyngeal region for the purpose of recording electrical activity. |
| • Needle Electrode (FDA Code: GXZ / 882.1350) A needle electrode is a device which is placed subcutaneously to stimulate or to record electrical signals. |
| • Oximeters |
| • Paper Chart Recorder (FDA Code: DSF / 870.2810) A paper chart recorder is a device used to print on paper, and create a permanent record of the signal from, for example, a physiological amplifier, signal conditioner, or computer. |
| • Photostimulator |
| • Physiological Signal Amplifier (FDA Code: GWL / 882.1835) A physiological signal amplifier is a general purpose device used to electrically amplify signals derived from various physiological sources (e.g., the electroencephalogram). |
| • Respiration Transducer |
| • Signal Isolation System (FDA Code: DRJ / 870.2600) A signal isolation system is a device that electrically isolates the patient from equipment connected to the commercial power supply received from a utility company. This isolation may be accomplished, for example, by transformer coupling, acoustic coupling, or optical coupling. |
