Description

Physiotherapy Nursing Bed

technical field

The invention relates to a physical therapy device, in particular to a physical therapy nursing bed.

Background technique

Patients whose lower limbs are damaged and unable to bend and walk normally need to receive physical therapy, but some patients with severely damaged lower limbs cannot perform independent rehabilitation courses at all, and can only achieve physical therapy through artificial control of lower limb movements by medical staff or family members. This will not only increase the burden on medical staff or family members, but also easily cause secondary injury to patients because the manual operation cannot guarantee the strength.

In addition, although the existing medical nursing beds all have the function of turning over the bed board, this function needs to be realized by adjusting the controller. If the patient with inconvenient lower limbs is sleeping, if he feels unwell, he cannot turn over in time. Rollover can only be carried out after waking up, which has a strong impact on the patient's sleep quality and is unfavorable for the patient's recovery.
