Abstract
A highly automated, fully-closed circuit rebreather and methods for operating the device by users with limited training and limited skill development are disclosed. Advanced sensors, electronics, software, assembly methods, and disposable cartridges dramatically reduce the skills required for assembly, operation, and maintenance of the unit. The use of the rebreather apparatus is primarily for recreational diving applications, but may be used for additional applications where the presence of breathable air may be absent or limited, such as hazardous duty applications, high altitude applications, no-atmosphere or low-atmosphere applications, and the like.
Claims14
A rebreather apparatus comprising;
- a closed loop respirator including a plurality of components;
- and
- a device that communicates with two or more of the plurality of components of the closed loop respirator and, using information received from and regarding the two or more of the plurality of the plurality of components, performs a self-training application for a user of the closed loop respirator and thereby provides the user with self-training in the proper assembly and operation of the closed loop respirator.
A rebreather apparatus comprising:
- a closed loop respirator;
- two or more components including:
- (1) a mask that includes augmented reality displays incorporated therewith that provide a self-training application;
- (2) a mask and a portable computing device, wherein sensors for the rebreather apparatus are distributed among two or more of the respirator, mask, and portable computing device;
- (3) smart-phone enabled operation;
- (4) one or more re-charge units that are removable and replaceable by a user of the closed loop respirator;
- (5) one or more directional RFID antennas adapted to detect respirator component location and/or orientation;
- (6) a disposable hose and counter-lung;
- (7) disposable one-way valves;
- (8) two counter-lung chambers using a common wall;
- (9) a single-unit dual counter-lung;
- (10) hydrogel in the closed loop respirator to immobilize liquids;
- (11) a breathing mask, a counter-lung, and a coaxial hose providing fluid communication between the breathing mask and counter-lung;
- (12) a disposable conformal seal in the closed loop respirator;
- (13) a taper conformal seal in the closed loop respirator;
- (14) a water-trap;
- (15) an integrated surface supply snorkel;
- (16) a convergent duct on an inhalation side of a carbon dioxide scrubber;
- (17) a divergent duct on an exhalation side of a carbon dioxide scrubber;
- and
- (18) a differential pressure sensor on each of exhalation and inhalation sides of the closed loop respirator;
- and
- a device that communicates with the two or more of the components and, using information received from and regarding the two or more of the plurality of the plurality of components, performs self-training application for a user of the closed loop respirator and thereby provides the user with self-training in the proper assembly and operation of the closed loop respirator.
A rebreather apparatus comprising;
- a closed loop respirator including a plurality of components;
- and
- a smartphone or tablet computer that communicates with two or more of the plurality of components of the closed loop respirator and, using information received from and regarding the two or more of the plurality of the plurality of components, performs a self-training application for a user of the closed loop respirator and thereby provides the user with self-training in the proper assembly and operation of the closed loop respirator.
