Patent attributes
A gel distribution apparatus can include modules so that each module is connected to a respective sensor of a sensor array included in headgear. Each module can be configured to facilitate the distribution of a gel onto a scalp of a patient to permit deployment of the gel at locations on the head of a patient near the sensor to which the module is adjacently positioned or attached. The modules can each include at least one flange to permit a user to pull the module away from the scalp while also pressing a compressible gel reservoir of the module toward the scalp for directing the gel onto the scalp. The pulling force can help counteract internal pressure generated from compression of the reservoir to expel the gel so that the gel flows along a desired gel flow path without excessive back pressure.
