when the bed is installed, the rehabilitation bed needs to be debugged firstly, according to the standard specified by the first part of medical electrical equipment, safety general requirements and the like, the bed at least bears 1700N load, the weight of a pregnant and lying-in woman is 100kg when the pregnant and lying-in woman lies on the bed according to the actual situation, the total weight of other accessories is 77.6kg, and the whole weight is 180kg, namely 1800N;

the angle of the left and right inclined design is 13 degrees, the pregnant and lying-in women can easily slide off the bed due to overlarge angle to cause injury on the body, the left and right inclined aims to facilitate the pregnant and lying-in women to get on and off the bed, and the angle is suitable for safety consideration.

And calculating the thrust required to be provided by the electric push rod as a model selection basis.

When lying, the gravity is pressed on the guiding axle under the bed board horizontality, and electric putter needs the power that provides to be minimum, when inclining to be 13 with horizontal contained angle, and the pole stretches out the biggest, and electric putter provides's power is the biggest, and pregnant and lying-in woman lies in the bed this moment, and the skew has taken place for the focus position.

Center of gravity shift distance d =970/2-970/2 × cos13 ° =17mm

The power putter needs to provide a moment that overcomes the force created between the shift in the center of gravity and gravity.

Calculating the formula: g x d = F push rod x L,

wherein L is the vertical distance between the thrust direction of the push rod and the support shaft, and d is the gravity center offset distance, and the unit is mm;

g is the load in N.

1800 x 17= F push rod x 183.5,

the calculation can obtain: f push rod =166.8N,

round F push bar =170N,

the safety coefficient K is generally 1.5-3, and 1.5 is taken

F pushrod max = F pushrod × K =170 × 1.5= 255N.

In conclusion, the reasonable model of the electric push rod is selected according to the thrust,

such as: FD3-I type electric push rods are selected, and the main parameters are as follows: the speed is 4.5 mm/s-100 mm/s; sasa albo-marginata load 1200N; the use temperature is-45 ℃ to 65 ℃; the limit switch is internally arranged and is not adjustable; protection class IP 65; 25% of full-load working system and 400N of rated load, meets the requirement of required thrust and meets the conditions.

In conclusion; the multifunctional rehabilitation bed for obstetrical nursing can help a pregnant woman to lift the limbs through adjustment, so that the blood circulation degree is improved, edema is reduced, family members and medical staff can be assisted to help the pregnant woman to turn over and get out of bed, and the family members can be effectively reminded to replace or pour out urine bags before the bed is accompanied by delivery.
