[0012] Preferably, the outer sealing ring is wrapped around the outer wall of the blood nozzle, and the outer sealing ring is a rubber outer sealing ring, which can further improve the sealing performance after installation.

[0013] Compared with the prior art, this utility model provides a blood perfusion device cap with good sealing effect, which has the following beneficial effects:

[0014] 1. This blood perfusion device cap, with its excellent sealing effect, uses fastening straps, tension straps, fixing plates, fixing grooves, fixing hooks, slots, and sealing gaskets to seal the connection between the cap and the blood perfusion device. The use of tension straps can fix the outer wall of the fastening straps, and the connection of fixing plates and fixing hooks can make the tension straps tightly clamp the fastening straps onto the blood perfusion device, improving the sealing effect.

[0015] 2. The well-sealed cap of this blood perfusion device integrates the filter screen onto the cap via an mounting block and filter screen, making the two components a single unit. This reduces the assembly process of the blood perfusion device, making it convenient to use and improving work efficiency. Furthermore, the two components do not require assembly and can be used directly, ensuring a tight seal and thus improving the overall sealing performance of the blood perfusion device. The filter screen can also more effectively filter toxic substances from the blood. Attached Figure Description
