| 20120298109 | HIGH PRESSURE AIR CYLINDERS FOR USE WITH SELF-CONTAINED BREATHING APPARATUS - A self-contained breathing apparatus includes an air cylinder pressurized to about 5500 psi, wherein the air cylinder is compatible with infrastructure used in conjunction with the air cylinder. The self-contained breathing apparatus also includes a first regulator valve for reducing air pressure from the air cylinder to a predetermined level. A second regulator valve is also provided for reducing the air pressure from the predetermined level to a level suitable for use by an operator, wherein air is supplied from the second regulator valve to the operator via a mask. The self-contained breathing apparatus further includes a frame for supporting the air cylinder on the back of the operator. Other embodiments are described and claimed. | 11-29-2012 |
| 20130239970 | NASAL CANNULA ADAPTER - A nasal cannula adapter. The nasal cannula adapter includes a chamber having cannula clips, and a connector having an opening and a connector lumen in communication with the chamber and the opening. Systems for administering a gas to a patient comprise the nasal cannula adapter, a nasal cannula, and an airway device. Methods for administering a gas to a patient comprise administering a gas through a nasal cannula operably connected to the nasal cannula adapter operably connected to an airway device inserted into the airway of the patient. | 09-19-2013 |
| 20130333704 | Wrist Worn Portable Breathing Apparatus - The present invention, WristOx, is designed as a means of providing a user with means of extracting multiple breaths in situations that do not allow for the use of a traditional SCUBA configuration. The interchangeable compressed air cylinders allow for the user to exchange spent cylinders for full cylinders on the fly. Designed to be worn unobtrusively on the arm, the present invention foregoes the need for hoses or a second stage regulator, allowing for use in activities such as kayaking, spelunking, or even as an additional line of defense for divers and fire rescue personnel. | 12-19-2013 |
| 20140076322 | High Pressure Air Cylinders for Use with Self-Contained Breathing Apparatus - A self-contained breathing apparatus includes an air cylinder pressurized to about 5500 psig, wherein the air cylinder is compatible with infrastructure used in conjunction with the air cylinder. The self-contained breathing apparatus also includes a first regulator valve for reducing air pressure from the air cylinder to a predetermined level.

| 20140283838 | Diving Equipment - Diving equipment includes a compressed air bottle connected to a breathing apparatus and an inflatable jacket via which buoyancy is balanced by the jacket being connected to the compressed air bottle to be inflated or to an outlet to be deflated. A monitoring device is activated via a control valve as a function of surrounding water pressure and has a time monitoring unit which, after the expiry of a defined time and in the absence of breathing activity in the breathing apparatus, changes to emergency operation and activates an emergency valve via a control line connecting the jacket to the compressed air bottle to force inflation of the jacket. Actuation of at least one regulating valve is influenced during a dive by the monitoring device and/or the control valve. In manual activation, the jacket is inflated via the inflation valve, and the compressed air is bled via the outlet valve. | 09-25-2014 |
