Properties | Details |
---|---|
SFDA Classification | Class IIb |
Purpose of Use | Monitor and record the electrical activity of the muscles. |
Work Location & End-User | Work location: hospital wards End-User: Doctor |
Parts & Accessories | • computer • battery • Electrodes and wires Pickup types: • Superficial: more widely used and more extensive in capturing electrical signals Consists of: small metal disc Made of silver chloride • needle Consists of: A very thin wire is inserted into the muscle Insulated metal conducts electricity on one side and exposed on the other his problems: The muscle may be involuntarily tightened as a result of pain, which leads to inaccuracy |
Operation | The current is sent through the nerve and then the signal from the muscle contraction is measured After the signal received from the electrodes is amplified it is displayed on the computer Connection: Patient head > Electrodes > Amplification > Recording > Signal display Device information is taken by: muscle capacity muscle succession The fibers that make up the muscle |
Common Problems | The need to replace the consumable parts Malfunction of the electrode connections and the electrical circuit Faulty signal pickup may occur due to noise from ambient light and electrical appliances Problem solving: Signal amplification Noise removal through filtration |
