Warwick Technology Limited is the manufacturer and supplier of the Digital Breathing Machine, an engineered solution for recreating human breathing for test and research purposes.The Digital Breathing Machine has been developed to provide an accurate method of reproducing human respiration. A standard breathing machine uses a simple motor driven cam to drive a piston, and is therefore limited to producing a sine wave breathing pattern. This machine uses an electric actuator to directly control the precise position of the piston, enabling any breathing waveform to be reproduced. Human breathing can be recorded using an optional measurement system, and then the machine can reproduce this accurately and repeatably in the laboratory. The machine has been designed to be capable of exceeding the breathing performance of even the fittest human.The machine has been re-designed to use a high quality PTFE/rubber seal around the piston edge, enabling the direct use of the machine as part of the pressure circuit for leak tests etc. The piston seal is capable of seals pressures in excess of 50 bar, though at these elevated pressures the piston needs pressure balancing to reduce the load on the actuator for greater accuracy of reproduction. New for 2020 is the cough/sneeze option, which features extra software to enable the accurate recreation of cough and sneeze sequences. An external valve is also provided to simulate the throat and allow the temporary increases in lung pressure associated with coughing.
