Abstract:
Objective To analyze the technical features of spherical,cuboid and flat-bottomed oxygen chambers,so as to provide reference for the hospital in the selection of oxygen chamber types.Methods Key main technical indexes of air pressurized oxygen chamber were analyzed and fundamental basis and evidences for chamber selection were identified,through comparison of the main technical advantages and disadvantages of oxygen chamber with different shapes.Results Traditional spherical oxygen chamber has the features of simple structure and low manufacturing cost.However,it must meet the requirements of the sunken chamber installation and is usually difficult in site selection of chamber construction.Furthermore,huge cost is often involved in the construction of basement with low comprehensive cost effectiveness.Cuboid shape oxygen chamber has higher chamber capacity per capita and more effective chamber length,as compared with those of same size spherical chamber,and vision inside the chamber is identical to that of the ward.However,shortcomings of sunken chamber installation and huge cost of capital construction are avoidable.Furthermore,there are disadvantages of lower chamber pressure capacity,huge dead weight of the chamber body and high cost of chamber construction.Flat-bottomed oxygen chambers could be directly installed on the first floor of the building with a load capacity of 1 ton per square meter,so that the pre-requirement and the cost of basement construction of the oxygen chamber could be avoided.Though the flat-bottomed oxygen chamber has the disadvantages of lower chamber capacity per capita,more complicated chamber structure and partial increase in manufacturing cost,as compared with the same size spherical chamber,it possesses the advantages of good spatial chamber vision and effective chamber length.Therefore,comprehensive cost effectiveness of the flatbottomed oxygen chamber is better than that of the spherical one.The building condition of the oxygen chamber is the key factor for the selection of the oxygen chamber.Conclusion In view of the strains in hospital medical spaces and better comprehensive cost effectiveness of the flat-bottomed oxygen chamber,the flat-bottomed oxygen chamber promises a better prospect,when compared with the spherical and cuboid ones.
