Abstract: A package delivery apparatus for securing delivered packages includes a flexible bag, a security strap, and a locking mechanism. The flexible bag is configured to accommodate one or more packages and includes an opening adjustable between an open position and a closed position. The security strap is integrated with the bag and cinches around the opening. The locking mechanism selectively allows the security strap to move in one direction to secure the closed position. The locking mechanism includes a housing, a lock element, a ratcheting mechanism, and a handle mechanism. The security strap extends through the housing and the ratcheting mechanism and is coupled to the handle mechanism. Moving the handle mechanism to an extended position cinches and locks the bag closed. The lock element is selectively actuated to disengage the security strap from the ratcheting mechanism and allow the bag to be re-opened.

Abstract: Disclosed herein are modules for performing hyperbaric oxygen therapy (“HBOT”) on a patient submerged in pressurized water where substantially no gas is present in the module. The modules generally have an entry, a fluid inlet for introducing water into the module, first and second fluid outlets positioned substantially at a base and a top of the module respectively, and a utilities inlet and outlet in part for transferring breathing air to and from the patient. The module permits HBOT treatment on a patient submerged in water with no air in the module, thus reducing the risk of fire or explosion. Methods and systems are also contemplated. Disclosed herein are methods of filling a module with water until there is substantially no gas in the module, and providing the patient in the module with treatment air during HBOT treatment.
