The invention relates to a bag in bottle breathing unit (10) for use in anaesthetic or resuscitation equipment for a patient, the bag in bottle unit including a breathing bag (30b) mounted within a chamber (11), the chamber being adapted to be connected (61a) to an external gas source, and the bag interior being adapted to be connected to the breathing circuit of a patient (21a, 21b), the arrangement being such that variation of pressure in the chamber will cause the patient to inhale or exhale according to whether the pressure is increased or reduced respectively, wherein the bag is easily separably connected in the breathing circuit (22), thereby facilitating enabling sterilisation or disposal of the parts after each patient treatment. The breathing unit is moveable between two operating locations diametrically opposed when the bag is suspended from the integral, or projects vertically upwards thereform. The bag may be a bellows (30a) or a smooth bag type (30b) in the same breathing unit. The unit is easily dismantled and assembled without the need for tools. |
