A new safety system for air filtration in clinical suction apparatus
1Department of Surgery, Royal Postgraduate Medical School, Hammersmith Hospital, London.
Abstract:
The design and development of a low cost differential pressure indicator giving continual pressure comparison across the substance of an air filter is described. A hazard warning is given when the differential pressure rises above a pre-set value proportional to significant loss of filter efficiency. The differential pressure indicator affords increased protection against infection associated with the use of suction apparatus and allows a net saving in expenditure by ensuring optimum use of integral air filters.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
