Claim:
A medicinal liquid supply apparatus comprising: a fixed-type medicinal liquid supply volume controller ( 40 ) connected to one end of a first medicinal liquid hose ( 30 ) whose the other end is connected to an outlet of a medicinal liquid supplier ( 10 ), the fixed-type medicinal liquid supply volume controller ( 40 ) comprising: cases ( 41 a ; 41 b ); a medicinal liquid control line ( 42 ) received inside the cases ( 41 a ; 41 b ); an inflow part ( 43 ) and an outflow part ( 44 ) respectively formed on opposite ends of the medicinal liquid control line ( 42 ) and each respectively comprising a plurality of branch holes ( 43 a ; 44 a ); a controller 45 joined to an outer face of the case ( 41 a or 41 b ); a pressure plate ( 46 ) pressed according to a rotation angle of the controller ( 45 ) and comprising a plurality of pressure pieces ( 46 a ); and a plurality of medicinal liquid branch hoses ( 48 ) and a medicinal liquid transfer hose ( 47 ) one end of each respectively connected to the branch holes ( 43 a ) of the inflow part and another end of each respectively connected to the branch holes ( 44 a ) of the outflow part, the medicinal liquid branch hoses ( 48 ) between the inflow part and the outflow part being opened and closed by an action of the pressure plate ( 46 ), the medicinal liquid transfer hose ( 47 ) between the inflow part and the outflow part being always opened; a double medicinal liquid hose ( 50 ) comprising a plurality of tubes, wherein the plurality of tubes are of different radii and share substantially a same longitudinal axis, one end of a first tube of the plurality of tubes being connected to an outlet of the fixed-type medicinal liquid supply volume controller ( 40 ), one end of a second tube of the plurality of tubes of the double medicinal liquid hose ( 50 ) comprising a branch tube ( 51 ) connected to the medicinal liquid transfer hose ( 47 ); and an arbitrary medicinal liquid supply volume controller ( 60 ) connected to an other end of the double medicinal liquid hose ( 50 ), the arbitrary medicinal liquid supply volume controller ( 60 ) comprising: a medicinal liquid storing tube ( 63 ) for storing the medicinal liquid, which is transferred through the branch tube ( 51 ) of the double medicinal liquid hose ( 50 ), via a branch tube ( 64 ) of the arbitrary medicinal liquid supply volume controller ( 60 ); a check valve ( 65 ) adapted to allow the medicinal liquid storing tube ( 63 ) to temporarily store the medicinal liquid therein and prevent a back flow of the medicinal liquid; a button body ( 61 ) adapted to pressurize the medicinal liquid storing tube ( 63 ) to thereby arbitrarily and additionally supply the medicinal liquid through a second medicinal liquid hose ( 70 ); and a bypass tube ( 66 ) connected to the double medicinal liquid hose ( 50 ) for transferring the medicinal liquid transferred through the double medicinal liquid hose ( 50 ) to the second medicinal liquid hose ( 70 ) to thereby continuously supply the medicinal liquid.
