Intelligent adaptor for a breathing training device

An intelligent adaptor for a pressure threshold breathing training device, the adaptor comprising:

• a first end configured to attach to a mouthpiece of a the pressure threshold breathing training device;
• a second end configured to be received into a mouth of a user, such that a seal is created in use around the second end of the adaptor;
• the first and second ends being connected by a passageway, the passageway being configured to provide a sealed chamber, in use, between at least the lungs of the user and the mouthpiece of the pressure threshold breathing training device, such that if a measured pressure within the passageway of the adaptor crosses a threshold value, a resistance valve located within the pressure threshold breathing training device moves from a first to a second configuration to allow the user to breathe freely through the device in the second configuration;
• the adaptor further comprising a control system comprising:
• a pressure sensor configured to measure a user generated pressure within the passageway at pre-defined increments of time during a training session;
• and,
• a transceiver configured to receive pressure measurement data from the pressure sensor, and transmit the data to a computing device for analysis.
