An ECT, EEG, EMG, ENG or impedance pneumography hospital electrode is designed for use on neonates in high humidity environments, such as in a high humidity incubator. The electrode includes a silver-silver/chloride sensor; a signal transmitting lead connected to the sensor; and an electrically conductive, self-adhesive gel which electrically connects the sensor to the patient's skin. The conductive, self-adhesive gel is formed from a hydrogel which is hydrophilic in nature. In order to stabilize the adhesiveness of the gel in the high humidity environment, the gel is provided with an adjunct non-hydrophilic adhesive member which provides improved adhesion to the skin while maintaining contact between the conductive gel and the patient's skin. The use of the adjunct adhesive member enables the electrode assembly to be used in the high humidity environment for extended periods of time without becoming detached from the patient's skin.
A medical electrode for use in a high relative humidity neonatal care environment, said electrode assembly comprising:
In a medical electrode of the type having an electrical signal sensor and a self adhesive and electrically conductive hydrophilic hydrogel member having a skin-contacting surface, which hydrogel member is connected to the sensor for transmitting electrical signals from a patient's skin to the sensor, the improvement comprising an adjunct adhesive member which surrounds the hydrogel member and has an adjunct skin-contacting surface which is coextensive with the hydrogel member skin-contacting surface, said adjunct member being able to retain its adhesiveness in environments having a relative humidity of more than about 50% so as to maintain adhesion to a patient's skin after the hydrogel member has essentially lost its adhesiveness due to water absorption for the humid environment.
