A stretcher that can be rolled up may comprise at least two straps for securing a person in a longitudinal direction of the stretcher. The at least two straps for securing the person in the longitudinal direction of the stretcher are disposed such that the at least two straps are fastened above a first region. The first region may be configured to accommodate shoulders of the person. The stretcher may further comprises a foot plate that is adjustable in the longitudinal direction of the stretcher. In addition, a deployable buoyancy device may be mounted on the stretcher. The deployable buoyancy device may be fastened in a second region on the stretcher, wherein the second region is configured to accommodate the person's neck. The deployable buoyancy device may have a tubular configuration, and the deployable buoyancy device may be connected in the second region to the at least two straps for securing the person in the longitudinal direction.”

A rapid water ambulance for transport of patients, comprising a sick bay solidly constrained to a structure of the water ambulance and support apparatus (10) for a stretcher, the support apparatus (10) comprises: a support column (20), a carriage (30) slidable along the column (20) in the direction of the axis (A) thereof, a support plane (11) for a stretcher, borne projectingly by the carriage (30) and solidly constrained thereto, a damped suspension device (33), constrained to the carriage (30) and to the column (20), which supports the support plane (11) at an operating height, wherein the axis (A) of the support column (20) is inclined with respect to the perpendicular direction to a floor (P) plane of the sick bay and lies in a vertical plane parallel to the motion direction of the water ambulance.

An autonomous navigation type marine buoy includes: a buoy body consisting of a floating body; an internal sensor; a detection unit that receives a GPS signal and information of the internal sensor; an on-water exploration unit that explores a state on a sea; an underwater exploration unit that explores a state under the sea; a determination unit that creates a navigation plan for the buoy body; a propulsion unit that propels the buoy body; a navigation control unit that performs drive control of the propulsion unit so that the buoy body navigates according to the navigation plan; a power generation unit; a power storage unit; a communication unit that communicates with an outside; an emergency signal unit that receives a distress signal and specifies a transmission position of the distress signal; and an evacuation room that accommodates a victim, in which the autonomous navigation type marine buoy has an autonomous navigation mode of performing autonomous navigation to a set position on the sea, a home position mode of autonomously holding a home position at the set position on the sea, and a rescue mode of performing autonomous navigation to the transmission position of the distress signal on the sea when the distress signal is received.

An underwater rescue system, including a submersible and a rescue cage. The submersible includes a housing, a turntable and a motor. The turntable is rotatably arranged at an outer surface of the housing. The motor is fixed on the housing and connected to the turntable. The rescue cage includes a connecting rod, a first lifebuoy, a second lifebuoy and an air charging device. A lower end of the connecting rod is provided with an electromagnetic chuck attracting the turntable. An upper end of the connecting rod is connected to the first lifebuoy. A bottom of the first lifebuoy is provided with a load-bearing net. A side of the first lifebuoy is connected to the second lifebuoy by a net bag. The air charging device communicates with the first and second lifebuoys and is configured to charge air to the first and second lifebuoys.
