Handheld nasal stimulator with safety mechanism

A method of a handheld stimulator device, the method comprising:

• coupling a stimulator probe of the handheld stimulator device to a stimulator body of the handheld stimulator device, the stimulator probe comprising:
• a nasal insertion prong comprising an electrode;
• a deformable element comprising an electrically conductive material and configured to assist with allowing stimulus delivery from the electrode of the stimulator probe, the deformable element forming an original state prior to a use of the stimulator probe and forming a deformed state after the use of the stimulator probe;
• and
• the stimulator body comprising:
• a power source;
• and
• at least one contact pin comprising an electrically conductive material and in electrical communication with the power source, the at least one contact pin positioned along the stimulator body to, during coupling of the stimulator body to the stimulator probe, form an initial contact configuration with the deformable element in the original state and cause the deformable element to transition into the deformed state, the formation of the initial contact configuration and the deformable element in the deformed state allowing delivery of a stimulus from the stimulator probe;
• forming, as a result of the coupling, an initial contact configuration between the at least one contact pin and the deformable element in the original state;
• deforming, as a result of the coupling, the deformable element into the deformed state;
• and
• allowing, as a result of the forming and the deforming, delivery of a stimulus from the electrode of the stimulator probe.
