Zusammenfassung:The provision of a fluid mixture delivery instrument which can mix two types of fluid and then send them upstream, and which is simple to operate. A tube 24 is arranged inside a downstream pipe 14 in a fluid mixture delivery instrument A which is provided with an upstream pipe 13, downstream pipe 14 and a merging pipe 12 which are respectively connected to a chamber part 11, and also the downstream pipe 14 is provided with pressure parts 23 for closing off the tube 24 by the application of pressure. Furthermore, two pressure parts 23 are provided, one either side of the tube 24. In addition, the pressure parts 23 are provided at one end of a rocking piece 22, the other end of which is supported outside a fluid mixture delivery instrument main body 10. The downstream end of the tube 24 is then fixed to the inner peripheral surface of the downstream pipe 14 by a fixing member 25.
