[0037] Align each strip plate 610 with the hole in the middle of the corresponding barrel loop 601, and then push the guide tube 2 downward. Under the gravity of the structure itself and the limiting effect of the clamp ring 609, the strip plate 610 will gradually penetrate into the barrel loop 601 and support the guide tube 2, completing the assembly of the blood storage barrel 1 and the guide tube 2.

The opening and closing assembly 7 also includes a shaft rod 707 inserted and arranged on the outer surface of the top ring 602, a sealing plate 706 is fixedly connected to the outer surface of the shaft rod 707 extending into the top ring 602, and the sealing plate 706 is arranged on the inner wall of the top ring 602, the shaft rod 707 is rotatably connected to the top ring 602, a torsion spring 710 is sleeved on the outer surface of the shaft rod 707, a rope 708 is fixedly connected to the end of the shaft rod 707, and a ring 709 is fixedly connected to the bottom end of the rope 708, and the ring 709 is sleeved on the outer surface of the hook 705;

[0039] When the pedal 702 is stepped on downward, the spring 704 will be squeezed while the pedal 702 moves downward. At the same time, under the action of the hook 705 and the ring 709, the pedal 702 moves downward and pulls the shaft rod 707 to rotate through the rope 708. The shaft rod 707 rotates to squeeze the torsion spring 710 and drives the sealing plate 706 to rotate, so that the diversion tube 2 is opened, and blood can flow from the diversion tube 2 into the blood storage bucket 1. There is no need for manual operation by medical staff. It is simpler, faster and more labor-saving by stepping on it, and it will not affect the normal work of the medical staff's hands. After releasing the pedal 702, under the action of the spring 704 and the torsion spring 710, the pedal 702 will rise to the initial height, and the shaft rod 707 will flip and drive the sealing plate 706 to close the diversion tube 2, thereby realizing free control of the opening and closing of the diversion tube 2.

[0040] like Figures 7 to 9 As shown, the cleaning assembly 8 includes a motor 802 arranged in the bottom interlayer of the blood storage bucket 1, the driving end of the motor 802 is fixedly connected to a center piece 803, the center piece 803 is movably connected to the bottom interlayer plate of the blood storage bucket 1, a horizontal rolling brush 804 is movably interspersed on the outer surface of the center piece 803, and a vertical rolling brush 807 is movably connected to the end of the horizontal rolling brush 804 away from the center piece 803, and a bevel gear 805 is fixedly connected to the upper part of the bottom interlayer plate of the blood storage bucket 1. One end of the horizontal rolling brush 804 extending into the center piece 803 is fixedly connected to a bevel gear 2 806, and the bevel gear 2 806 is meshed with the bevel gear 1 805. The upper part of the inner wall of the blood storage bucket 1 is fixedly connected to the inner ring 801, and the top of the vertical rolling brush 807 is movably connected to the lower part of the inner ring 801. The upper part of the outer surface of the vertical rolling brush 807 is fixedly sleeved with a spur gear 808. The inner wall of the blood storage bucket 1 is distributed with tooth blocks 809 in an annular matrix, and the spur gears 808 are meshed with the tooth blocks 809.

[0041] The motor 802 drives the center piece 803 to rotate. When the center piece 803 rotates, it will drive the horizontal rolling brush 804 and the vertical rolling brush 807 to rotate synchronously around the center piece 803. The horizontal rolling brush 804 can clean the bottom of the blood storage bucket 1, and the vertical rolling brush 807 can clean the side wall of the blood storage bucket 1.

Then, the horizontal rolling brush 804 and the vertical rolling brush 807 will rotate while rotating around the center piece 803, thereby achieving the purpose of improving the cleaning effect.

[0042] According to the technical solution provided by the present invention, during the delivery process, the collecting basin 3 is placed under the buttocks of the pregnant woman. The upper opening of the collecting basin 3 is fan-shaped and can fit the buttocks of the pregnant woman to ensure that blood and other liquids can flow into the basin. The first sensor 4 can measure the amount of liquid in the basin and display it on the calculation display 5. If the pregnant woman has a large amount of bleeding, the blood in the collecting basin 3 can be discharged into the blood storage bucket 1 through the diversion tube 2 through the opening and closing component 7. The liquid can be layered according to its density. The second sensor 9 can be used to intelligently calculate the amount of amniotic fluid or urine and blood according to the difference in specific gravity of the liquid, and it can also be displayed on the calculation display 5, so that the amount of bleeding can be accurately measured. The principles and calculation methods of the blood storage bucket 1, the sensor and the calculation display 5 are existing technologies and will not be elaborated on here. Before use, the blood storage bucket 1, the diversion tube 2 and the collecting basin 3 need to be spliced ​​together. The diversion tube 2 and the blood storage bucket 1 are assembled first, and each strip plate 610 is aligned with the middle of the corresponding barrel loop 601. The blood storage bucket 1 and the blood collection tube 2 are assembled. Then, the plug-in 604 at the bottom of the collection basin 3 is aligned with the circular groove 603 and inserted. The arc plate 606 is rotated around the center of the top ring 602. The arc plate 606 drives the arc pin 607 to slide in the pin groove 608 and insert into the pin hole 605. The lower surface of the arc pin 607 is an inclined surface, so the initial insertion is easy. As the arc pin 607 moves, the bottom surface of the arc pin 607 will abut against the inner wall of the pin hole 605, thereby locking the plug 604 and ensuring the stability of the docking. Finally, the collar 709 is sleeved on the hook 705, thereby realizing the rapid disassembly and assembly of the blood storage bucket 1, the guide tube 2 and the collection basin 3, improving the disassembly and assembly efficiency and facilitating the subsequent cleaning and disinfection. When disassembling, just follow the installation steps and invert the operation;

[0043] When the blood in the collection basin 3 needs to be discharged into the blood storage bucket 1, the medical staff steps on the pedal 702 downward. The pedal 702 moves downward and squeezes the spring 704. At the same time, under the action of the hook 705 and the ring 709, the pedal 702 moves downward and pulls the shaft rod 707 to rotate through the rope 708. The shaft rod 707 rotates to squeeze the torsion spring 710 and drive the sealing plate 706 to rotate, so that the diversion tube 2 is opened and the blood can flow from the diversion tube 2 into the blood storage bucket 1. There is no need for manual operation by the medical staff. The stepping method is simpler, faster and more labor-saving, and will not affect the normal work of the medical staff's hands. After releasing the pedal 702, under the action of the spring 704 and the torsion spring 710, the pedal 702 will rise to the initial height, the shaft rod 707 will flip and drive the sealing plate 706 to close the diversion tube 2, so as to realize the free control of the opening and closing of the diversion tube 2. When the liquid in the blood storage bucket 1 is to be discharged, the solenoid valve tube 10 is started, and then clean water and cleaning solution are added into the blood storage bucket, and the motor 802 is started. The motor 802 drives the center piece 803 to rotate. While the center piece 803 rotates, it will drive the horizontal rolling brush 804 and the vertical rolling brush 807 to rotate synchronously around the center piece 803. The horizontal rolling brush 804 can clean the bottom of the blood storage bucket 1, and the vertical rolling brush 807 can clean the side wall of the blood storage bucket 1. At the same time, one end of the horizontal rolling brush 804 extending into the center piece 803 is meshed with the bevel gear 806 through the bevel gear 1 805, and the upper part of the vertical rolling brush 807 is meshed with the tooth block 809 through the spur gear 808, so that the horizontal rolling brush 804 and the vertical rolling brush 807 will rotate while rotating around the center piece 803, thereby achieving the purpose of improving the cleaning effect. The sewage after cleaning is also discharged through the solenoid valve tube 10.
