Mechanism Design and Simulation Analysis of Multifunctional

Nursing Bed

Abstract--This research develops a new multifunctional nursing bed

that can realize the movements of turning left and right sides and

defecating on the bed for clinical use. And use the ADAMS to

analysis the effects to the motor torque from the force on the

rotated board, friction of contact pair and space position. By

analysis of dynamic on the model of the main mechanism can get

the curves and the influences of torque, which plays an important

guiding role in selecting appropriate motor and installation structure.

Keywords-- nursing bed、 ADAMS、 dynamic analysis

I. INTRODUCTION

Nursing beds as parts of medical equipments are necessary for

hospital care, and has been widely used in hospitals, nursing homes,

retirement homes and many other fields. However, the prices of good quality

nursing beds are expensive, the new study can reduce the cost and

the difficult of care, for example, to the patients resting on the bed

for a long time, their turning over and lifting back required

nurses have sufficient physical strength. Common beds just have head

up, leg flexion and extension functions, this bed adds the function as

rolling around, defecating on the bed and so on as needed [1].

II. MECHANISM DESIGN

The nursing bed can be divided into four parts by the

structure and function as: bed body, control cabinet, a framework

for activities, removable bed pan. Block diagram as in Fig. 1.

In the control cubicle, the installment has the master control

board, the motor-driven board, the transformer, the switching power

supply and so on. The control cubicle connects with the nursing bed by the

connection. Except the fixed mechanism, the bed body also includes

the drive motor and the vane organization. The active frame installment

has the wheels, which may be separated from the nursing bed. In

the frame there are the water tank, stool which can rise and fall

and the hot air blower. The transportable bed pan also installs wheels and

can insert into the active frame. In addition, the control system also

includes the wire operators, the LCD and so on. In the system

there are six DC motors which complete the actions of rising and falling

of the head, the flexion of the leg, rolling around of the left

and right, opening and closing of the vane and rising and falling of the stool

and so on.

A. Bed Function

The bed activity functions including the rising and falling of the head, the

flexion of the leg and the bed body turn sides which satisfied

patient's active request basically, favors the patients to improve their

blood circulation and prevents the bedsore. This nursing bed has

designed the flexion of the leg conforms to human body's

movement characteristic. The bed body side turns may divide into three

movements: the left side to turn, the right side to turn and

the even side. Fig. 2, Fig. 3, Fig. 4 is the bed body's three

movements.

B. Nursing Function

The defecation function is rare in other electric nursing bed which
