A filling method of a peritoneal dialysis solution bag with a splash-proof self-cleaning function comprises the following steps:
s1: firstly, the height of the water level sensor 4 is adjusted to be 85% of the set capacity of the filling bag 12;
s2: the turntable 1 rotates to convey an empty filling bag 12 to the lower part of the centering and holding mechanism 14;
s3: the power device 2 is pressed down to drive the filling head 6 to move downwards, the centering enclasping mechanism 14 enclasps the filling port 13, and then filling is started;
s4: when the liquid level in the filling bag 12 reaches the detection height of the water level sensor 4, the splash-proof mechanism 34 is started to break up the liquid column, so that the filling is continued until the filling is completed;
s5: after filling is completed, the power device 2 is pressed down to drive the filling head 6 to move upwards, so that the filling head 6 is pulled out from the filling opening 13, and at the moment, the cleaning mechanism 44 operates, so that the water absorbing sponge 48 absorbs residual liquid drops on the filling head 6 completely.
Working principle: the water level sensor 4 is connected to a controller, which is connected to a power input end of the splash guard 34, and before the device is operated, a worker adjusts the level detected by the water level sensor 4 to 85% of the set capacity of the filling bag 12.
When the device performs filling operation, the rotary table 1 operates to bring an empty filling bag 12 to the lower part of the filling head 6, the power machine 2 is pressed down to drive the filling head 6 to move downwards, after the positioning pressing plate 33 abuts against the rotary table 1, the power machine 2 is pressed down to continue to operate, at this time, the filling head 6 continues to drive the fixing plate 11 to move downwards, when the fixing plate 11 moves downwards, the first switching tube 52 is contracted inwards towards the second switching tube 59, the second abutting spring 57 is stressed to compress, and in the process, the second switching tube 59 abuts against the movable rod 54 to move downwards, the movable rod 54 abuts against the third abutting spring 58 to move downwards, the third abutting spring 58 is stressed to compress, and the driver 51 does not drive the cleaner 45 to operate.
When the third abutting spring 58 is compressed, the fixed plate 11 drives the movable ring plate 15 to move downwards, when the movable ring plate 15 is pressed downwards to enable the first inclined block 16 to abut against the second inclined block 28, the first pressure spring 24 is compressed under stress, as the movable ring plate 15 continues to be pressed downwards, the first inclined block 16 abuts against the second inclined block 28 to enable the rotary ring plate 26 to rotate, when the rotary ring plate 26 rotates, the sliding groove 27 also rotates along with the rotation of the rotary ring plate 26, at the moment, the limiting rectangular block 30 abuts against the sliding groove 27, the limiting rod 31 abuts against the movable sliding block 22 to drive the movable sliding block 22 to slide along the rectangular sliding groove 21, when the movable sliding block 22 slides along the length direction of the rectangular sliding groove 21, the second pressure spring 23 is compressed under stress, and therefore all holding claws 29 hold the filling opening 13 together when the limiting rectangular block 30 rotates along with the sliding groove 27. After the holding claw 29 holds the filling opening 13 tightly, the filling head 6 is driven by the pressing power machine 2 to move downwards until the filling head 6 stretches into the filling opening 13, then the pressing power machine 2 pauses moving, and at the moment, filling liquid starts to fill into the filling bag 12 from the liquid inlet pipe 7 through the filling head 6. When the liquid in the filling bag 12 reaches the detection line of the water level sensor 4, the water level sensor 4 transmits signals to the controller, the controller enables the two mini linear push rods 35 to be started to push the U-shaped frame 37 to move, the U-shaped frame 37 moves to drive the first deflector rod 41 and the second deflector rod 43 to rotate against the waist hole 38, so that the first sector plate 39 and the second sector plate 42 are unfolded, at the moment, the liquid column flowing out of the filling head 6 is blocked by the unfolded first sector plate 39 and the unfolded second sector plate 42, but because the first sector plate 39 and the second sector plate 42 are provided with a plurality of water outlet holes 40, the blocked liquid column enters the filling bag 12 through each water outlet hole 40, the impact force of the liquid column is reduced through the scattering of the water outlet holes 40, the liquid at the filling head 6 is continuously filled with the original pressure until the filling is completed, and the water flow disperser 36 breaks the liquid column to reduce the impact force, so that the liquid is prevented from splashing out of the filling opening 13 to cause pollution, but the filling speed is not influenced.
After the filling head 6 finishes filling, when the filling is finished, the fixing plate 11 moves upwards, the second abutting spring 57 resets, so that the first adapter tube 52 resets, and at the moment, the third abutting spring 58 resets and abuts against the movable rod 54 to move upwards, so that the abutting inclined plate 55 abuts against the abutting ball head 49, the sliding rod 47 transversely extends, and the water absorbing sponge 48 is attached to the filling head 6 to absorb residual liquid drops. It should be noted that, when the filling head 6 moves downward with the fixing plate 11, the movable rod 54 is driven to move downward, so that the abutting inclined plate 55 is separated from the abutting ball 49, and the sliding rod 47 is reset, so that the water absorbing sponge 48 is reset. The water absorbing sponge 48 is pushed onto the filling head 6 to absorb the residual liquid drops, so that pollution caused by the residual liquid drops falling onto the filling bag 12 when the filling head 6 is reset is avoided. After filling is completed, the pressing power device 2 drives the filling head 6 to move upwards, at the moment, the first pressure spring 24 releases pressure to enable the movable annular plate 15 to return to the initial position, at the moment, the first inclined block 16 is separated from the second inclined block 28, the second pressure spring 23 releases pressure to enable the movable sliding block 22 to return to the initial position, at the moment, the limiting rod 31 is driven by the movable sliding block 22 to move and reset, the limiting rod 31 drives the holding claw 29 to reset, the holding claw 29 drives the limiting rectangular block 30 to abut against the sliding groove 27 to move, and therefore the rotary annular plate 26 is reversely reset, after the device resets, the turntable 1 operates to continuously drive the next empty filling bag 12 to be conveyed to the lower side of the filling head 6 to wait for filling.
