PUMPING DEVICE FOR MEDICAL PURPOSE

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.
