Definitions

  • One aspect of the following disclosure is a housing having an internal space for storing blood therein, an introduction section for introducing intracardiac blood into the housing, and a device provided under the introduction section and protruding toward the internal space. and a bag-shaped filter that covers the outside of the defoaming member, and the defoaming member is connected to the lower end of the introduction section and has a first tapered portion whose diameter decreases downward. and an opening provided at the lower end of the first tapered portion; a defoaming sponge disposed outside the first guide member; and spaced outward from the first guide member. and a second guide member for supporting the defoaming sponge.
  • the housing 12 is made of a transparent or translucent resin material, and the position of the liquid surface of the blood stored in the internal space 12a can be visually recognized from the outside.
  • the resin material forming the housing 12 include polycarbonate, acrylic resin, polyethylene terephthalate, polyethylene, polypropylene, polystyrene, polyvinyl chloride, and ABS resin.
  • a plurality of scale lines 36 for grasping the volume of stored blood are formed on the outer periphery of the housing 12 so as to extend in the horizontal direction.
  • the interior of the flow channel projection 66 forms a flow channel 66 a whose lower side opens toward the upper surface 60 a of the collecting portion 60 .
  • the flow path 66a is formed along a smooth curve along the upper surface 60a, allowing the blood to flow along the upper surface 60a without causing bubbles.
  • a groove 82 is formed in the central portion of the inclined wall 76a in the circumferential direction so as to be concave toward the outside. As shown in FIG. 3, the inclined wall 76a is spaced apart from the defoaming sponge 70 at the groove 82 to form a flow path through which the blood flowing out from the defoaming sponge 70 flows downward.
  • a plurality of partition plates 104 are formed to protrude short sideways from the current plate 102 .
  • the partition plate 104 extends downward so as to partition the portion between the outflow holes 90 adjacent in the longitudinal direction, and regulates the flow of blood flowing out from the outflow holes 90 .
  • venous blood flows in from the venous blood flow inlet port 14 and intracardiac blood flows in from the intracardiac blood flow inlet port 16 .
  • the venous blood flows into the internal space 12 a of the blood reservoir 10 after air bubbles are removed by the air bubble removing filter 44 of the venous blood filtering section 38 .
  • the second guide member 72 may further include a side wall portion 88 extending downward from the second taper portion 76 and a bottom plate 86 supporting the lower end portion of the side wall portion 88 .
  • the defoaming sponge 70 can be sandwiched and held in the gap between the projecting portion 94 and the side wall portion 88 .
  • the blood flowing out from the defoaming sponge 70 can be collected near the bottom plate 86 .
