Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b):

a TPU suction tube, as shown in figures 1 and 5, comprises a suction tube body 1 and a liquid suction head 11 arranged at the end part of the suction tube body, wherein the inside of the liquid suction head 11 is hollow to form a blood suction cavity 112, the outer wall of the liquid suction head 11 is provided with a plurality of blood suction holes 111 communicated with the blood suction cavity 112, the TPU suction tube further comprises a tail end reserved conduit 12 communicated with the liquid suction head 11, the tail end reserved conduit 12 comprises blood suction hollow spheres 121 which are arranged in series, and each blood suction hollow sphere 121 is provided with a plurality of polygonal blood suction holes 122; by providing the hollow blood suction ball 121 at the end of the liquid suction head 11, a plurality of blood inlet ports are formed, so that blood can be sucked from a plurality of ports, and when a certain part is blocked, other alternative ports are provided.

As shown in fig. 1, the reserved distal end conduit 12 includes a main tube 125, the hollow blood suction balls 121 are communicated with the main tube 125 and are arranged in a staggered manner, and the polygonal blood suction holes 122 are hexagonal.
