Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
A closed ECMO autoblood recovery system characterized in that: comprises a sodium chloride crystal solution bag 1, a centrifugal pump 2, an oxygenator 3, a whole blood storage bag 4, a Y-shaped connector 5, an ECMO drainage tube 6, a blood return tube 7, a medical three-way tube 8, a side branch tube 9 and a centrifugal branch tube 10; the Y-shaped connector 5 is used for connecting the ECMO drainage tube 6 and the sodium chloride crystal solution bag 1; the centrifugal branch pipe 10 is used for connecting the centrifugal pump 2 and the oxygenator 3; the port of the blood return pipe 7 is connected with the side branch connecting pipe 9 through the medical three-way pipe 8, and one end of the side branch connecting pipe 9 is connected with the whole blood storage bag 4. The sodium chloride crystal solution bag 1 is a 500ml 0.9% NACL crystal solution bag.
As a possible embodiment, two ends of the Y-shaped connector 5 are respectively connected with the sodium chloride crystal solution bags 1, and the medical three-way pipe 8 is arranged in the middle of the Y-shaped connector 5; the medical three-way pipe 8 is arranged at the joint of the Y-shaped connector 5 and the ECMO drainage tube 6.
As a possible implementation mode, one end of the ECMO drainage tube 6 is connected to the human body, and the other end is connected to the upper end of the centrifugal pump 2; one end of the blood return pipe 7 is connected with the human body, and the other end is connected with the oxygenator 3.
As a possible embodiment, the centrifugal pump 2 is provided with a flow sensor 202 on its side. The centrifugal pump 2 is used for flushing residual blood in the machine into the whole blood storage bag 4 for storage; the flow sensor 202 may be a YF-S201 water flow sensor.
As a possible implementation mode, when the machine is withdrawn, the ECMO drainage tube at the left side 6 of the Y-shaped connector and the pipeline at the front 7 of the blood vessel side branch interface are tightened, so that a closed loop is formed. The tubing in ECMO blood was flushed with two bags of 500mL of 0.9% NACL crystal solution into 400mL of blood into a CPD whole blood reservoir by ECMO centrifugal pump 2 at 1500 revolutions. In the collection process, the blood bag is continuously shaken lightly, and a weighing form is adopted, so that the risk of thrombosis caused by excess is avoided.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
