ABSTRACT:
In anaesthetics evaporators, the gas flow conducted through them is enriched with an anaesthetic contained in the evaporator to a desired concentration. In the anaesthetics evaporator the gas flow is divided into two part flows, the by-pass flow and the evaporating chamber flow. Both part flows are regulated by valves and regulators to obtain an exact relative flow ratio. To achieve this, this ratio must be maintained and monitored. The monitoring equipment is simple and can be retrofitted. It includes a differential pressure measuring instrument and a thermometer with a holder. The differential pressure measuring instrument is a differential pressure manometer connected via hoses and an adapter to both the inlet and outlet of the gas flow to the anaesthetics units. The thermometer to measure the evaporating temperature is fastened in well heat conducting manner to the anaesthetics evaporator by means of a holder. Temperature and differential pressure changes between inlet and outlet of the gas flow upstream and downstream of the evaporator would indicate possible changes in the part flow ratios relative to each other.
