A disposable venous blood pressure manometer of provided which includes a transparent tray having a longitudinal interior channel with a transparent plastic manometer tube disposed in the channel, a calibrated scale member in the tray behind the tube, and a cover closing the back of the tray and which may be used as a label. The cover and body member provide a container which may contain a plastic extension tube and a three-way valve. The container can be opened by peeling back a bottom end portion of the cover from the body member. The extension tube and valve can then be removed for use in connecting the manometer tube in an infusion and pressure measuring system. The level of liquid in the manometer tube during use and the scale can be seen through the transparent tray for taking pressure readings. The container performs a functional part of the manometer during use.
