Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

the blood transfusion device comprises an in-vivo tube 1, wherein the front part and the middle part of the in-vivo tube 1 are respectively provided with a side hole 4, the side holes 4 penetrate through the in-vivo tube 1, in actual use, the blood filled in the left atrium flows into the in-vivo tube 1 through the side holes 4, flows out of the body through a blood leading-out opening 7 and plays a role of blood transfusion, the number of the side holes 4 is at least 5, the front part of the in-vivo tube 1 is fixedly provided with an air bag 3, the air bag 3 is of an oblong structure, the air bag 3 filled with physiological saline can be clamped on the left ventricle side of a mechanical valve, or for a mitral valve, the air bag after water injection can be clamped at a biological valve opening and is not easy to loosen, multiple connections after dropping are avoided, and; and the external body tube 2, its fixed right-hand member that sets up at internal body tube 1, the right side of external body tube 2 is provided with blood and draws forth mouth 7, be used for discharging blood extracorporeally, sufficient blood passes through side opening 4 in the left atrium, internal body tube 1, external body tube 2, check valve 6, blood draws forth mouth 7 and discharges, check valve 6 has effectively prevented the entering of air, gasbag pipe 5 is fixed to be set up in the inner chamber of internal body tube 1, gasbag pipe 5 one section extends out from internal body tube 1 lateral wall, gasbag pipe 5 communicates with gasbag 3 each other, normal saline gets into gasbag 3 through the gasbag pipe 5 that extends, make gasbag 3 swell, and then the card is in mechanical valve's left ventricle side, prevent the landing of internal body tube 1.
