摘要： PURPOSE: To detect a closing of hose quickly as same as an air presence to prevent the patient from becoming dangerous by providing an evaluation circuit responding to emitting heat from a heater element to generate an output-signal, whenever there is no presence of fluid flow emitting heat adjacent to the heater element or whenever there is a presence of air bubbles insulating heat. CONSTITUTION: If any liquid leakage exists in the hose 14 channel, the flowing liquid emits heat from the flow sensor 17 to lower the resistance value of the resistor element 19, which causes the measuring bridge to deviate from the balance to generate a difference in voltage between two inputs from the current source 29 feeding much more current to the measuring bridge. Consequently, the current increases both at the two branches. This results in increasing the resistance value of the resistor element 19, until the bridge circuit is balanced once again, for an increase in heating up the resistor element 19. The current source 19 is thus adjusted so that the current heat generated via the resistance value 19 becomes equal to the heat to be taken away selectively from the resistance via the liquid flow. The output signal from the current source 29 is indicated by a voltmeter 30, through which the user obtains the information about a size of flow.

摘要： PURPOSE: To enable a multiple application despite a single structure and, moreover, exhibiting individual appearances according to modes by selecting a mode using an external data medium having a marker means observable from outside a housing. CONSTITUTION: A plate-shaped marker means 35 is mounted at the right angle to a coding bar at the rear end part of a data medium 30 viewed from the direction of inserting the data medium. When the data medium 30 is inserted, it gets in contact with a stopper of a housing 13 to regulate the inserting action thereof. The marker means 35 is colored differently from the front 14 or a control panel 19 to allow clear discrimination in the mounting of the data medium on the housing 13. With regard to the data medium 30, in a different mode, the coloring of the marker means 35 is differentiated and characters are written into the marker means 35 to allow identification from outside thereby achieving a mutual identification thereof.

摘要： PURPOSE: To make high-precision pressure measurement possible by changing the vibration of stationary vibrating coils corresponding to the position of a working member. CONSTITUTION: A bar 17 composed of a flexible spring fixed and supported at one end pushes a pressure member 11 against the hose part 11 of a filling conduit for pressure measurement. A working member 19 which cooperates with vibrating coils 22, 23 being stationary is arranged at the external free end of the bar 17. the length of the lever arm part of the pressure member 11 and that of the lever arm part of the working member 19 differ, and a gain corresponding to the relation between the lengths of these two lever arm parts is produced. The frequency, magnitude of vibration or other parameters change corresponding to the nearness of the working member 19 to the vibrating coils 22, 23, and noncontact detection of the position of the working member 19 becomes possible. Consequently, it becomes possible to measure a pressure with high precision even in the case of long-term use and under various kinds of environmental conditions as well.

摘要： PURPOSE: To surely observe a desired transfusion rate by giving code informations showing determined values of respective transfusion amount or scattering from predetermined transfusion amounts to independent pumping hoses. CONSTITUTION: Code plate 22 with a code information 22a is mounted to a hose 13. Furthermore, a fixing means 23 is equipped in a housing 10 in such a way that the hose is inserted only at a specified position and thus the code plate 22 is also at a specified position. A read-out means 26 is mounted on a housing wall 25. Values expressed by the code information to be corrected are inputted into a microcomputer and the microcomputer corrects a control signal output for a driving motor 18. An actual transfusion rate is adjusted to a predetermined transfusion rate expressed, with consideration for respective allowance of houses.
