Document Type and Number:
WIPO Patent Application WO/2012/169527
Kind Code:
A1
Abstract:
[Problem] To provide a mixing device that can reliably prevent unintended mixing of a secondary liquid into a main part even if a malfunction or the like occurs in an opening/closing means and can prevent breakage of said opening/closing means or a secondary channel even if a malfunction or the like occurs in a pressurizing means and said pressurizing means operates erroneously. [Solution] A mixing device provided with the following: a pipe (L20) through which water for dilution is transported; a pipe (L17) through which an antiseptic solution is transported; a pressurizing pump (15) that circulates the antiseptic solution in the second pipe (L17) towards the first pipe (L20); a check valve (16) that can open and close the second pipe (L17); a discharge channel (L18) that branches off from the second pipe (L17) between the check valve (16) and the pressurizing pump (15) and can discharge the water for dilution or the antiseptic solution; and an electromagnetic valve (17) that, when the antiseptic solution is not to be mixed with the water for dilution, can bring the pressure in the second pipe (L17) between the check valve (16) and the pressurizing pump (15) below the pressure in the first pipe (L20).
