<p>A solution infusion system for infusing a solution (3) into a patient (8) is provided with a solution housing (16) having two surfaces (18, 24). These surfaces (18, 24) are in abutment with each other when the system is in operation. A solution tube (6) for leading the solution (3) towards the patient (8) must be properly placed in a tube path (20) formed on one of the two surfaces (18, 24) for the normal operation of the system. A pair of pressure sensors (30) are disposed on respective sides of the tube path (20) to detect whether the solution tube (6) is properly placed in the tube path (20). Each of the pressure sensors (30) outputs a detection signal in association with the placement of the solution tube (6). The solution infusion system is also provided with a control unit (10) for controlling the amount of the solution (3) to be fed through the solution tube (6). When the solution tube (6) deviates off the tube path (20), the control unit (10) gives a warning in response to the detection signal outputted from the pressure sensors (30). <IMAGE></p> |
