SYSTEM FOR PERFORMING MEDICAL PRODUCT INFUSION AND CARBON DIOXIDE MONITORING Russian patent published in 2007 - IPC A61M16/01 A61M5/142 A61B5/00 

FIELD: medical engineering.

SUBSTANCE: system is usable for introducing liquid medication to the patient in performing his/her physical condition monitoring, that is, the liquid is introduced under expired air control with given component under observation. The monitoring system has interface unit, the infusion pump unit, and capnographic unit. The infusion pump unit is used for introducing liquid medication to the patient, including anesthetizing, anesthetizing or somnifacient drugs introduction. Capnographic unit allows controlling air, exhaled by the patient, in particular, final flux and reflux levels of carbon dioxide gas content in expired air and frequency of breath. Capnographic unit giving instructions to the interface unit that final flux and reflux level of carbon dioxide gas content in expired air and frequency of breath have reached the values violating certain reference values stored in memory, the interface unit starts producing visual and acoustic alarm signals and controls infusion pump unit operation by modifying air flow or by switching-off the pump unit. In controllable anesthesia application cases, the interface unit can block bolus dozes of anesthetizing drug supplied to patient under control until they will be repeatedly set by qualified medical personnel or until measured capnographic sizes will return to their normal variation range. The interface unit also has communication ports, which the interface unit can use for submitting signals to external devices to warn the medical personnel.

EFFECT: enabled quality of liquid drugs introduction.
