While none of these potential problems in themselve provide a satisfactory explanation of the reported failures, modifications to the R2D would serve to improve function. In June 2020, the in- ventor withdrew the R2D from sale in order for the changes listed to be incorporated. It is expected that the modified R2D will be available again in mid August 2020.
1. The double-tubing carrying exhaled gas will be replaced with a single tube.
2. Soda lime canisters will be replaced with a screw-top model. 3.Reinforcement of the tube/ canister connection points and re- placement clip connectors for tubing and counter-lung. 4. Soda lime canisters will be supplied sealed and unfitted, allow- ing full testing of the system with no compromise of the scrubber. 5. A redesigned and packaged counter lung with insert that does not require pre-inflation. 6. An instruction video will be provided in order to facilitate test- ing ofthe system and connection of the scrubbers prior to use.
A number of the original R2D DeBreathers are in circulation and some will perhaps be used before the ReDesigned R2D becomes available.
Exit would appreciate any reports of experiences, both positive or negative, with the device. This feedback information will be made available in future updates to this book.
