状に備えている。 The liquid branching device, for example, the medical liquid branching device 1, can be made of synthetic resin such as vinyl chloride resin or polycarbonate, but transparent resin is preferable because the inside can be seen. Also, although soft and hard resins can be used, they must be hard enough not to deform the flow path. The medical liquid branching device 1 includes an inlet side liquid flow path 3
radially includes a branch part 2a having a diameter A, and other branch parts 2b and 2c each having two outlet-side liquid flow paths 3b and 3c communicating with the liquid flow path 3a.

ためには５ｂ，５ｃは相似形が好ましい。 The inlet liquid flow path 3a is divided by a distribution wall 4 provided downstream thereof into passages 5b and 5c of equal cross-sectional area, as shown in FIG. If the cross-sectional areas of the passages 5b and 5c are different in shape, the flow resistance will be different even if the areas are the same.

Tubes 6, 7 and 8 are connected to a, 2b and 2c, respectively. It is better to connect the tube by inserting it into the branch part so that the inner surface of the tube and the wall surface of the liquid passage in the branch part are flush with each other so that there is less resistance. Of course, the tubes 7 and 8 are connected to the branch parts 2b and 2.
This does not preclude it from being fitted into c.
