How to say "in-patient" in Japanese

• 入院患者にゅういんかんじゃ
  nounThe usual word for an in-patient: someone admitted to and staying in a hospital. It covers the ordinary medical sense of 'in-patient' in everyday and clinical contexts, though it is itself less common than related expressions.
  入院にゅういん患者かんじゃは医者いしゃに麻酔ますいを注射ちゅうしゃされてすぐに眠ねむりに落おちた。↗

  The hospital patient dropped off shortly after the doctor injected him with anesthesia.
• 収容者しゅうようしゃ
  nounMeans a person confined or housed in an institution; the gloss extends it to a hospital in-patient, but that hospital use is less common. It is really the word for residents or detainees of an institution rather than patients.

Use 入院患者 for a hospital in-patient; 収容者 chiefly means someone confined in an institution and is a less common way to refer to a hospital in-patient.
