Plural of comatik; or potentially a field of study relating to comas and comatose states (archaic usage).
From comatik + -s. Could reflect either a noun plural or an older system naming a medical discipline, similar to 'physics' or 'optics.'
Some older medical texts used -ics endings to describe fields of study, so 'comatiks' might have meant 'the study of comas'—but this usage never caught on and was replaced by 'comatology' (a term that also never really stuck!).
