1、多功能护理床的设备设计和功能分析英文翻译中英文 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 t

2、he effects to the motor torque from the force on the rotated board, friction of contact pair and space positionBy 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 installat

3、ion structure Keywords- nursing bed、 ADAMS、 dynamic analysisIINTRODUCTION 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 ex

4、pensive, 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 strengthCommon beds just have head up, leg flexion and extension functions, this bed add

5、s the function as rolling around, defecating on the bed and so on as needed 1II MECHANISMDESIGN 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 Fig1 In the control cubicle,

6、the installment has the master control board, the motor-driven board, the transformer, the switching power supply and so onThe 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 organizationThe active f

7、rame installment has the wheels, which may be separated from the nursing bedIn the frame there are the water tank, stool which can rise and fall and the hot air blowerThe transportable bed pan also installs wheels and can insert into the active frameIn addition, the control system also includes the

8、wire operators, the LCD and so onIn 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 onABed Function The bed activi

9、ty functions including the rising and falling of the head, the flexion of the leg and the bed body turn sides which satisfied patients active request basically, favors the patients to improve their blood circulation and prevents the bedsoreThis nursing bed has designed the flexion of the leg conform

10、s to human bodys 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 sideFig. 2,Fig. 3,Fig. 4 is the bed bodys three movements.BNursing Function The defecation function is rare in other electric nursing bed whic

11、h suits the paralysis patient especiallyIn the middle of the bed body there is a rectangular opening, where can only seen two vanes in the normal conditionWhen defecating, the vane turns down to makes a breach, then the defecation device rise. After the defecation completed, the vane upturns continu

12、es to fill the gap. The defecation device is composed of the active frame and the motion bed pan which can inserts into the frame, and the entire frame can coordinate to load the bed body. The nursing bed can also provide the functions of spraying water and dryingIn the active frame installed the wa

13、ter tank, the hot air blower and the solenoid valve. The water tank has a water pump, heater, the temperature sensor and the water level sensorIt can be realized that the water temperature establishment, the water temperature maintains and the water tank volume automatic increase and so on under the

14、 controllers control The patient who is sick bed in long-term is the major recipients of this nursing bed. Before defecate, press the key stool raise on the remote control, two vanes open, and then the stool raise, plate of the stool erects automatically, and so as to the bed pan. The patient can de

15、fecate after these movements completedAfter the defecation completes, press corresponding key, carries on the flushing first, then uses hot blast drying, which has manifested the human nursing function. The water for flushing is preserved in the tank, and use heating wire to maintain the temperature

16、. Its needed to gather and process of the temperature in order to realize the control of it, the gather can completed by the sensor, the process and control can completed by the monolithic integrated circuitAs a result of the patients defecate time is uncertainty, and requests maintains the temperature constant, for the aim of providing appropriate temperature momentarilyIII. SYSTEM MODELINGAModeling Nursing bed is a very complex structure, which can divided in
