someone who is using a bed in a hospital although they no longer need hospital treatment, because they do not have anywhere else to go where they can be cared for safely. Some people consider this word offensive.

The hospital is currently accommodating 25 bed blockers who are healthy enough to leave. 医院里目前有25名健康程度已可出院的床位封锁患者。

Ralph could have ended up in residential care before his time, or as a hospital bed-blocker because there's no one to care for him back home. 因为家中无人照料他，拉尔夫可能会提早进入老人院，或成为医院的床位封锁患者。
