A tube cylinder in which an elastic tube communicating with a liquid supply source is wound around the outer periphery of the pressing cylinder and fixed so that it can be aligned, and a plurality of pressing cylinders that rotate planetarily in parallel with the axis on the outer periphery of the tube cylinder. A roller, one end of the plurality of pressure roller shafts is fixed in a cylindrical manner on the circumference, a fixing ring having a through hole through which the tube tube is inserted, and the other end of the pressure roller shafts are fixed at equal positions on the circumference, and the tube is fixed. A liquid injection pump comprising a roller shaft retaining ring having a through hole through which the tube is inserted and joined to a driving means, the pressing roller presses the elastic tube at at least two points, and the liquid is circulated by moving the pressing points, The roller shaft retaining ring is provided with a shaft supporting means for supporting the other fixed shaft of one of the pressing rollers so that the pressing roller can rotate around the retaining ring surface, A locking means that allows the fixing shaft to be attached to and detached from the fixing ring and a radial insertion groove that allows the tube to be inserted therethrough are bored, making it possible to attach and detach the tube from the position of the upwardly rotated press roller. Infusion pump. 2. It has a storage means for storing a stop signal for stopping the driving means, and a detection means for detecting the position where the insertion groove of the fixing ring allows the tube, etc. to be attached or removed, and the signals from the storage means and the detection means are generated simultaneously. 2. The infusion pump according to claim 1, wherein the driving means is stopped when the infusion pump is activated. 3. Pressing is carried out in a tube tube consisting of a hollow press tube with a spiral groove bored on its outer periphery, and an elastic tube that is wound around the external spiral groove from one end surface of the press tube and reaches the other end, through which the infusion fluid flows in and out. 2. The infusion pump according to claim 1, wherein a locking surface is provided on a part of the outer periphery of the inflow end of the tube, and an annular collar is provided at the end of the spiral groove of the pressing tube. 4 The cross-sectional shape of the elastic tube wound around the tube tube is defined as the bottom side, the convex portions forming both ends of the base side, and the both convex portions connected, and the side facing the bottom side as a continuously curved top portion, and the inside of the top portion 4. The elastic tube according to claim 1, wherein the elastic tube has an elliptical hollow portion that expands into both convex portions.
