Abstract
A disposable intravenous pump chamber assembly for an intravenous administration set which substantially reduces the problem of air bubble entrapment so that the amount of intravenous fluid delivered is effected in an accurate manner. The pump chamber assembly is specifically constructed to be utilized in conjunction with a diaphragm-type pump with external valving. The pump chamber cassette is held in the pump in a unique manner and includes a porting and fluid delivery arrangement which reduces the problem of air entrapment in the pump chamber.
