PROBLEM TO BE SOLVED: To provide a medical liquid supply tool simple in structure and capable of adjusting the injection amount of one shot of a medical liquid corresponding to the state of a patient or the like. SOLUTION: This medical liquid supply tool is provided with a casing, a chamber 31 for storing the medical liquid, a diaphragm (elastic body) 7 for forming a part of it, a clamping member 8, the flow-in port 32b and flow-out port 33 of the liquid chemicals communicated with the chamber 31, a button 62 to be protoruded inside the chamber 31 by pressurizing the diaphragm 7, a spring 65 for energizing the button 62, a button housing 61 screwed with the button 62, an orifice for flow rate control and a flow rate changeover means 9 capable of setting the flow rate of the liquid chemicals in at least two stages. When the button 62 whose position is adjusted to the button housing 61 is pressurized against the energizing force of the spring 65, the diaphragm 7 is protruded inside the chamber 31, the capacity of the chamber 31 is reduced and the medical liquid by the portion of the reduction is ejected from the flow-out port 33. |
