[0037] Working principle:
[0038] In the specific operation, the shell 1 and its accessories are placed on the table in the delivery room to ensure that they are in a relatively safe sterile area, and then a plurality of disposable separation cylinders 4 are taken out for standby and ensure that they are clean and not used;
[0039] When the parturient woman starts to deliver, one of the separation cylinders 4 is used to receive the mixed liquid of amniotic fluid and blood flowing out, and after being filled, it is placed on the rotating drum 3 inside one of the grooves 2 and covered with a cover to avoid being thrown out during the separation process, and then another separation cylinder 4 is taken out to continue receiving the mixed liquid of amniotic fluid and blood flowing out of the parturient woman;
[0040] After the filled separation cylinder 4 is placed inside the rotating drum 3, the rotating drum 3 and the separation cylinder 4 are keyed by the cooperation of the limiting groove 19 and the limiting block 18, and then one of the motors 17 is controlled to drive the rotating drum 3 to rotate, and the rotating drum 3 carries the separation cylinder 4 to rotate, and then the amniotic fluid and blood inside the separation cylinder 4 are separated under the action of centrifugal force, and at this time the structure of the mixed liquid is presented as the lower layer is blood and the upper layer is amniotic fluid after a little standing;
[0041] Thereafter, a container 16 is placed below the hollow rod 5, and then a medical worker operates the slide rod 7 to make the plug 8 inside the hollow rod 5 present four states:
[0042] The first state, the medical worker pulls up the slide rod 7, which drives the plug 8 to move upward in the hollow rod 5, and when the first separation port 9 coincides with one of the cutouts 101, the blood or amniotic fluid on one side of the curved plate 6 inside the separation cylinder 4 can be discharged and flow along the through hole 11 to the container 16 below.
[0043] The second state, the medical worker continues to pull up the slide rod 7, which drives the plug 8 to continue moving upward in the hollow rod 5, and when the second separation port 10 coincides with the other cutout 101, the blood or amniotic fluid on the other side of the curved plate 6 inside the separation cylinder 4 can be discharged and flow along the through hole 11 to the container 16 below.
[0044] It is worth noting here that: no matter the first state or the second state, when any one of the first separation port 9 or the second separation port 10 is communicated with the through hole 11, the other is blocked by the side wall of the hollow rod 5.
[0045] The third state, the medical staff pushes the slide rod 7 to the part of the plug head 8 completely above the cutout 101, the first separation port 9 and the second separation port 10 are both completely opened, at this time the blood or amniotic fluid on both sides of the curved plate 6 in the separation cylinder 4 can be discharged at the same time, and flows along the through hole 11 to the container 16 below;
[0046] By operating the blood or amniotic fluid can be selectively discharged, by the setting of the curved plate 6 not only can separate the amniotic fluid and blood with the separation cylinder 4, but also can separate the separation cylinder 4 into two space parts with the slide rod 7 and the plug head 8 to use, and separate the internal liquid or discharge together, improve the practicability of the equipment.
[0047] The fourth state, the medical staff pushes the slide rod 7 to the upper part of the plug head 8 to completely block the cutout 101, the liquid in the separation cylinder 4 cannot be discharged from the first separation port 9 or the second separation port 10, at this time the state should be when the medical staff uses the separation cylinder 4 to receive the blood or amniotic fluid of the puerpera, to ensure that the separation cylinder 4 will not leak liquid.
[0048] The medical staff separates and packs the liquid in the second or subsequent separation cylinder 4 by the same operation as described above, which will not be described here, it can be understood that the medical staff should use the container 16 to receive the blood and amniotic fluid, and then the medical staff can observe whether the blood flow of the puerpera is too much according to the blood received in the container 16, and detect the blood in time and give timely advice, which guarantees the safety of the puerpera;
[0049] Since the blood or amniotic fluid or its mixture of the puerpera during delivery is a continuous process, and this process cannot be carried out at the same time as the separation process using the blood separator, the setting of the two rotating cylinders 3 and their accessories can be operated in succession (i.e. double-station blood and amniotic fluid separation equipment), which ensures that the medical staff can continuously detect the blood flow of the puerpera (especially the amount of blood flow), ensures the timeliness of the data information, and provides protection for the safety of the puerpera.
