Definitions

  • v Said receptacle is separated from said froth suppressor device by a distribution funnel which directs the liow of coronary blood onto the ⁇ froth suppressor device.
  • the froth suppressor device comprises a hollow vertical stem for admission of donor blood and perforated disks vertically spaced on the stem, each of which is coated with a foam-breaking compound.
  • the present invention relates to medical equipment and apparatus applicable for conducting surgical operations that involve the use of artificial blood circulation, namely, to vessels for holding spare blood and reception of coronary blood.
  • the proposed vessel can be successfully used with apparatus for artificial blood circulation, as well as with arrangements for coronary blood suction.
  • One prior-art device of this nature comprises a housing made as a hollow cylinder fabricated .from organic glass. At the top of the housing there is a receiving chamber or receptacle for coronary blood, provided with ⁇ a detachable cover and an inlet pipe for the coronary blood to flow in said inlet pipe being directed tangentially with respect to the receptacle walls.
  • a froth suppressor device formed by liat metal perforated disks coated with a foam breaking compound. The disks are somewhat spaced one above another on a hollow vertical stem secured on the receptacle cover. At its bottom the vessel has an outlet pipe for the blood to discharge.
  • Spare blood is poured through the central hole of the cover and iiows down through the hollow vertical stem into the bottom portion of the vessel.
  • Coronary blood sucked from the operational wound by conventional means that need not be described herein conveys air bubbles and is passed through a tangentially arranged inlet pipe into the receptacle, wherein a rotary flow of coronary blood is formed.
  • the blood falls onto the top disk of the froth suppressor device, then flows down through the perforations therein onto the subsequent disk and so on, thus consecutively flowing down from one disk onto another to deposit onto the vessel bottom. While owing down the blood is in contact with the foam breaking compound the disks are coated with, thus liberating the same of air bubbles.
  • the blood accumulated on the vessel bottom becomes suitable for being introduced into the circulatory system of a patient.
  • the prior-art vessel for containing spare blood and reception of coronary blood fails to ensure a reasonably eiiicacious .froth suppression, this being due to the fact that part ofblood flowing down from the blood receptacle, ⁇ gets splashed over the vessel walls, thus eluding the system offroth suppressing disks.
  • a perforated distribution funnel is provided at the vessel top above the stack of perforated disks.
  • the periphery of the distribution funnel adjoin the bottom edges of the blood receptacle walls.
  • the perforated disks may be of a convexo-concave shape, have different diameters ⁇ and be arranged with their convex or cambered outward surfaces facing oppositely so that the greater diameter disks are preferably arranged with their convex cambered surface down, whereas the smaller diameter disks are arranged with their cambered outward surface up.
  • the vessel for holding spare blood and reception of coronary blood comprises a housing 1 at the top of which there is provided a receptacle 2 for coronary blood, and a cover 3 therefor.
  • the blood receptacle 2 has an inlet pipe 4 for admitting the coronary blood of a patient, said inlet pipe being arranged tangentially with respect to the receptacle inner wall.
  • the housing 1 has an inlet pipe 5 for passing the venous blood of the patient in case the vessel is used as an intermediate blood container when regulating the outow of the venous blood of the patient in the artificial blood circulation system, and an outlet pipe 6 for discharging the blood from the vessel into an oxygenator (not illustrated in the drawing).
  • the frothsuppressor device which is basically a stack of perforatedA disks 7 and 8 coated with a foam-breaking compound, mounted on a vertical hollow stem 9 and being somewhat spaced one above another.
  • a perforated distribution funnel 10 Located above the top disk 7 is a perforated distribution funnel 10 likewise coated with a foam-breaking compound. The edges of the distribution funnel 10 adjoin the bottom edges of the walls of the blood receptacle 2.
  • the disks 7 and 8 are of a convexo-concave shape, the disk 7 of a greater diameter being arranged alternately with the smaller-diameter disks 8.
  • the disks 7 are mounted on the stem 9 convex-down, while the disks 8, convex-up.
  • the vessel for holding spare blood and reception of coronary blood functions as follows.
  • the donors blood is poured into the vessel through the hollow stem 9.
  • the iiow of the coronary blood of the patient is passed into the upper end of the inner space of the blood receptacle 2, wherein due to the inlet pipe 4 being arranged tangentially, a circulatory blood How is attained.
  • weight the blood decelerates its circulatory motion and flows down covering the inner surfaceof'the distribution funnel and through the perforations therein the blood gets onto subsequent disks 7 and 8 of the froth-suppressor device consecutively vowing'dovvn from the top disk onto the bottom one.
  • the distribution funnel 10 enables all of the blood toget onto the disks 7 and 8. While contacting the foam-breaking compound which coat the surface of the disks 7 and 8, the blood release the air bubbles with which the blood became enriched when sucked from the operational wound.
  • the arrangement of the disk 7 and 8, whereby the greater-diameter disks alternate the smaller-diameter ones and the disks convex surfaces are oriented in a definite manner ensures that the blood is in contact with the disks 7 and 8 throughout the surface area thereof, due to which fact the maximum froth suppressing effect is attainable.
  • the blood freed of air bubbles and accumulated at the vessel bottom, is passed through the outlet pipe 6 into the oxygenator (not shown in the drawing) and further into the patients artery.
  • a vessel for receiving and defoaming blood comprising a housing; a blood receiving receptacle located on the top portion of said housing; said receptacle having a tangential duct for admitting coronary blood thereinto; a cover on the receptacle; a froth suppressor device lo- ""tacle; said froth suppressor device comprising a hollow vertical stem for admission of donor blood passing ⁇ through said cover and receptacle and discharging into the housing, and perforated dish-like disks mounted transversely on said vertical stem in spaced positions one above another and coated with arfoam-breaking compound; the bottom of said receptacle comprising a perforated distribution funnel located directly above the uppermost of said disks; means in the bottom of said housing for lremoval of the treated blood and means in the cover to release gases.
  • a vessel as claimedin claim 1 wherein the outer periphery of said distribution funnel adjoins the bottom inner periphery of the Walls of said blood receptacle.
  • a vessel as claimed in claim 1, wherein said perforated disks are of a convexo-concave shape and of two different diameters and are arranged with their convex surfaces facing oppositely, the greater-diameter disks facing with their convex surfaces down and the smaller-diameter disks, convex up, said smaller diameter disks being interdigitated between said larger diameter disks.
