..... There's no traditional priest in this area ...

Maybe you can try to get them to wear the scapular, even if it means to wrap it around their wrist or ankle if they cannot wear it around their neck.

You really should not baptize anyone unless they ask for it, and even then only conditionally unless you're certain they've never been baptized. If they return to health after being baptized, you will be responsible to instruct them in the faith or at least get them to go to see a trad priest.   

Canon 752

§ 1. An adult should not be baptized unless he knowingly and with desire has been rightly instructed; moreover, he should be admonished to be sorry for sins.
§ 2. But in danger of death, if the adult is not able to be diligently instructed in the principal mysteries of the faith, it is sufficient for the conferral of baptism that he shows by some sign that he agrees with them and seriously commits himself to the observance of the mandates of the Christian religion.
§ 3. But if he is not able to ask for baptism, [yet] either before or during the present state he manifested in some probable way the intention of receiving it, he should be baptized under condition; if he later recovers and there is doubt about the validity of the baptism conferred, he should be baptized again under condition.


Canon 754

§ 1. The insane or mad should not be baptized unless they were such from birth or from before they attained the use of reason; and then they are to be baptized as if infants.
§ 2. If they have lucid intervals, while they are in possession of their senses, they can be baptized if they wish.
§ 3. If in imminent danger of death, they can likewise be baptized if before they were insane, they showed the desire of taking baptism.
§ 4. If they are in a coma or delirium, they can be baptized only when awake and desirous [of baptism]; but if danger of death occurs, the prescript of § 3 is to be observed.
