Patent ID: 8882086

Claim:
Rechargeable, resterilizable mixing device for mixing a physiological solution and a gas to create foam with microbubbles for use in endovascular treatments, the mixing device comprising a body in the shape of two inverted cones united by their bases, with a central cylindrical channel and inclined downward channels that intercept the central cylindrical channel at a bottom end of the body, the inclined downward channels containing a cylindrical recess at a top end, the mixing device further including a central valve support having a cylindrical base and a cone-shaped head, the cylindrical base of the central valve support including a sealing ring on an external surface and including an internal opening crossing a length of the central valve support, the internal opening having a cylindrical recess on a bottom end of the central valve support with a conical protrusion extending upward until a middle region of the length of the central valve support, the internal opening including a conical recess disposed between the conical protrusion and the cylindrical recess, the conical recess containing an inclined passage hole that enables communication between the internal opening and the external cylindrical surface of the central valve support, a cylindrical channel is disposed above the conical protrusion and communicates with an opening of a head seat ( 17 ), located in a region of the cone-shaped head of the central valve support, the opening of the head seat contains conical housing recesses to receive a conical tip of a head piece, thereby forming small passage openings the head piece including a cylindrical part with a staggered conical tip that forms a step adjacent a middle and enabling the formation of the small passage openings, openings are included above the tip that communicate with a luer channel, adjacent a bottom part of the mixing device there is a coupled connector comprising a thin cylindrical disk supported by the bottom end of the body and coupled with the internal opening of the central valve support by means of a threaded protrusion the coupled connector including a fitting nozzle to receive a hose.
