Abstract
An apparatus for controlling dispensing of medical gases, comprising a unit for supplying medical gas, connected hermetically by way of a tube to a gas dispenser connected to a patient, a detector located along the tube for detecting correct respiration of the patient with at least one pressure sensor that detects cyclic pressure increases inside the dispenser caused by patient expirations, binary output signals being conveyed by the sensor to the detector which compares periodicity of the signals with a reference physiological periodicity, and an alarm indicator controlled by the detector and activated if the periodicity does not occur.
Claims9
An apparatus for controlling medical gas dispensing for assisting respiration, comprising:
- a centralized or local unit for supplying medical gas;
- a tube;
- a gas dispenser connected to a patient, said unit being connected hermetically by way of said tube to said gas dispenser;
- a detector arranged along said tube for detecting correct respiration of the patient;
- at least one pressure sensor provided at said detector to detect cyclic increases in pressure inside said dispenser caused by patient expirations, said sensor conveying output signals of a binary type, to said detector, that compares periodicity of said output signals with a reference physiological periodicity;
- and an alarm indicator controlled by said detector for activation thereof upon lack of periodicity occurrence due to obstruction of said tube or detachment of the dispenser from the patient.
