Hospital Bed with Auxiliary Functions of Lateral Positioning and Transferring for Immobilized Patients

In observation of the present hospital, nursing works such as doing lateral rotation or transferring of immobilized patients are very labor intensive. Therefore, the purpose of this design was both for reducing the physical loading of nurses, and for preventing from sequential illness, relieving the uncomfortable feeling of prolonged bed ridden patients. This proposed bed has easy operation features, which not only can provide patients to change position from lying to sitting or feet rising gesture, but also can assist nurses to change lateral position of patients and transport patients from one bed to the other bed. The mechanical design concept of changing lateral position and transferring patient came from the transportation of patient by stretcher. This work revealed the functional mechanisms, they are: (I) Mechanism for assisting patient to rotate laterally that facilitate patient to change lateral position either right or left within the maximum angle by 80 degree and helps nurses to easily provide massage on the back of patients. (II) Mechanism for assisting patient to transport laterally from main bed to the other bed or moving carrier such as wheelchair. (III) Mechanism on moving carrier such as gurney to transform into wheelchair that helps patients to easily get off the main bed and maneuver to locations, where the medical treatment or recreation purpose are desired.
