Abstract

The present invention is a fall-prevention device for the backrest of a hospital bed, wherein fall-prevention devices are configured on both sides of the backrest rack which inclination angle can be adjusted. The fall-prevention device includes fall-prevention racks that are coupled to the both sides of the backrest rack of the hospital bed. The fall-prevention rack is located within the siderail and supported by a support member. The other end of the support member is activated by a linking rod that is pivotably connected to the siderail on one end and to the main bed frame on the other end. When the backrest rack is in flat position, the level distance between the linking rod and the backrest rack is the longest, thus the support member of the linking rod is unable to support the fall-prevention rack upward. When the backrest rack is in tilt position, by the change of the inclination angle of the backrest rack, one end of the inking rod is in fixed position and the other end is driven by the backrest rack to change the level distance between the linking rod and the backrest rack, so the support member is able to support the fall-prevention rack that would be turned on the backrest rack pivot part until the fall-prevention rack is in vertical position to securely support two sides of the patient and prevent the patient from falling without extra adjustment. Then the objectives of convenience in use and ensuring patients safety are attained.
