Compared with the prior art, the invention has the beneficial effects that:

(1) the height of the amniotic fluid overflow preventing device can be adjusted according to the condition of a puerpera in the using process, so that the requirements of different puerpera can be met, (namely when the puerpera does not have amniotic fluid to flow out and lie on a hospital bed for waiting for delivery, the amniotic fluid overflow preventing device needs to be stored in the storage tank, the upper end surface of the amniotic fluid overflow preventing device is flush with the bed plate II, when the puerpera lies on the bed body, the buttocks of the puerpera are clamped in the arc-shaped groove on the fixing block, the puerpera stores the fixing block in the storage tank under the action of the gravity of the buttocks, so that the whole comfort level of the bed body is improved, when the puerpera has the amniotic fluid to overflow, the buttocks of the puerpera need to be lifted, at the moment, the second telescopic rod II is started to ascend, the second telescopic rod II drives the fixing strip plate guide sliding plate to vertically slide upwards along the inner wall of the storage tank, the supporting plate and the fixing block on the supporting plate are also driven to move upwards, when the fixing block moves to the required height, the second telescopic rod II is stopped to ascend, and when the amniotic fluid flows out of the tissue between two adjacent puerpera supporting rollers on.

(2) The amniotic fluid overflow preventing device is fixed on the bed body through the mutual matching of the elastic rope, the fixed hook and the fixed ring, so when amniotic fluid of a lying-in woman flows out of the body, the amniotic fluid overflow preventing device is directly collected, the bed sheet and the surrounding environment cannot be polluted, and complicated matters of frequently replacing the bed sheet are avoided.

(3) The supporting mechanism is arranged in the arc-shaped groove and comprises a supporting mechanism and a supporting mechanism II which is positioned below the supporting mechanism , the supporting mechanism comprises a fixed frame which is composed of two parallel fixed long strips and two parallel connecting plates and is matched with the arc-shaped groove, and supporting rollers which are fixed in the fixed frame at equal intervals through bearings, the length direction of each supporting roller is parallel to the length direction of the fixed long strips, the supporting mechanism II comprises a third telescopic rod which is vertically fixed at the central position in the arc-shaped groove and is matched with the fixed frame, an arc-shaped fixed plate which is fixed at the free end of the three telescopic rods and is matched with the arc-shaped groove, and guide rollers which are fixed on the upper end surface of the arc-shaped fixed plate at equal intervals through the fixed rods, the maximum distance of the arc-shaped fixed plate which rises along the arc-shaped groove is smaller than the distance from each supporting roller to the bottom of the arc-shaped groove, the diameter of each guide roller is smaller than the distance between every two adjacent supporting rollers, guide rollers are correspondingly arranged between every two adjacent supporting rollers, when amniotic fluid flows out of the body, the amniotic fluid flows through a gap between the two adjacent supporting rollers on tissues positioned in the arc-shaped groove, and the tissue of the supporting mechanism , so that the tissue can be prevented from being.

(4) When the paper towel needs to be replaced, the parturient or the parturient can manually rotate the handle, and the used paper towel is rolled up by manually rotating the handle because the whole paper towel is continuous, meanwhile, the paper placing roller continues to place new paper towels, clean paper towels are replaced into the arc-shaped groove, and in the process of winding the used paper towels on the winding roller, under the action of the tensioning mechanism, the tensioning roller on the tensioning mechanism extrudes the paper towel wound on the winding roller, the amniotic fluid absorbed on the paper towel is extruded into the right chamber and finally discharged through the guide pipe, the amniotic fluid is prevented from overflowing to pollute the surrounding environment, the paper towel is not required to be replaced periodically by medical staff in the whole process of replacing the paper towel, the workload of the medical staff is reduced, and simultaneously, in the replacement process, the lying-in woman does not need to be moved, so that the situation that the lying-in woman needs to be moved in the replacement process to cause pain to the lying-in woman is avoided.

(5) When the arc-shaped fixing plate rises to the maximum distance, each guide roller penetrates through the space between the two corresponding supporting rollers and rises to the top ends of the supporting rollers, sticky substances are easily adhered to the supporting rollers when amniotic fluid flows out of a lying-in woman, at the moment, only the three telescopic rods need to be started to enable the arc-shaped fixing plate to drive the guide rollers fixed on the three guide rollers to rise, so that each guide roller correspondingly rises to the top ends of the two supporting rollers from the space between the two adjacent supporting rollers from the left side to the right side, all the guide rollers form a new supporting surface to support the buttocks of the lying-in woman, when all the guide rollers rise to the upper ends of the supporting surfaces formed by all the supporting rollers, the guide rollers play a tensioning role, paper towels located in the arc-shaped grooves are enabled to be in contact with the bottom ends of the two supporting rollers, at the moment, the handles are rotated, the paper towels located in the arc-shaped grooves drive the supporting rollers to rotate while moving towards the direction of the winding rollers, the sticky substances adhered to the supporting rollers are cleaned, after cleaning is finished, the three telescopic rods fall to the initial position of the supporting mechanism , and other people do not need to replace the cleaning device, and the device can be conveniently.

(6) The tensioning mechanism comprises a tensioning barrel fixed on the top end in the right cavity, a tensioning rod fixed in the tensioning barrel through a tensioning spring and a tensioning roller fixed on the bottom end of the tensioning rod, plays a tensioning role in the winding process to prevent rolled tissue wound on the winding roller from loosening, and meanwhile extrudes out amniotic fluid absorbed on the rolled tissue under the action of the tensioning mechanism in the winding process to be collected in the right cavity to prevent the amniotic fluid from overflowing to pollute the surrounding environment.

(7) The fixed anti-release piece is respectively hinged to the rotating shaft and the rotating shaft II through the damping shaft, so that the fixed anti-release piece can be shifted left and right along the axis where the fixed anti-release piece is located, when the fixed anti-release piece is shifted to be perpendicular to the movable shaft , a paper roll towel is conveniently sleeved on the paper placing roller, used paper rolls are rolled on the winding roller, and the used waste paper rolls are conveniently taken out of the winding roller.

Therefore, the invention collects the amniotic fluid on the basis of the bed sheet, avoids the amniotic fluid from polluting the bed sheet and the surrounding environment, improves the comfort level of the bed body, absorbs the overflowing amniotic fluid through the paper towel, does not need to move a puerpera when the paper towel is replaced, can automatically replace the puerpera without other personnel, and has simple operation.
