Objective To investigate and analyze the features of medical systems onboard foreign amphibious ships,and to design the extended medical system onboard a certain dock landing ship of our navy.Methods Six medical modules were transfered from the ship-borne medical system and were installed on the flight deck of the ship,and the ward medical system was installed in the helicopter hangar,so as to form the extended medical system with the main capacities of surgical operation,hospitalization and accessory medical support.Results The extended medical system had the capacity of accommodating no less than 100 casualties (100 beds) and could hold 4 operating tables.The time for the installation of the system would be no more than 24 hours.Conclusions The expanded medical system could meet the demands of mass casualty care at sea,and improve the medical capability in its multi-role mission of the dock landing ship.

Objective To develop a water station that can be loaded to a ship and supply freshwater. Methods The water station comprises the reverse osmosis seawater desalination device, pressure water tank, high pressure water pump, etc, with 40-feet international standard containers as the carrier. Results The water station can produce 80 t freshwater daily, and the quality of produced water conforms to the standards of the state and army for drinking water quality. Conclusion The water station, which has highly-compaction, strong-mobility, excellent-adaptability and high-automaticity, fits for a ship.

This paper introduces the Vest-style First-aid Kit which are newly developed for PLA.Adopting a vest structure the Vest-style First-aid Kit has the advantages of fully freeing both hands,and being fit for the ship confined space.Basic performance experiments,ergonomics tests and army tryout were performed and the results showed that the vest-style first-aid kit was scientifically designed,and easy to use,suiting the body,obviously saving physical energy.It has a reasonably designed interior medicine layout and can fulfill the requirements of first-aid operations in naval ships.
