Due to the increase in the lethality of modern war weapons, sudden disasters at sea, etc., may cause a significant increase in critical and seriously injured people; at the same time, due to the expansion of sea maneuvering areas, the distance between the wounded and land treatment agencies has increased significantly. This requires that a higher level of medical care must be provided to the frontier. For the injured, the most dangerous stage is the 10 minutes and 1 hour after the trauma, which are the "platinum time" and "golden time" for treatment respectively. If the wounded can be stabilized within this period of time, more than 40% can be rescued. According to statistics, 90% of the deaths on the battlefield and in disaster situations are caused by the fact that their injuries cannot be stabilized quickly. Therefore, in order to reduce the death rate due to injury, it is necessary to implement rapid and effective treatment for the critically wounded on the spot, which requires a variety of on-site emergency resuscitation equipment, equipment and medicines, especially the support of transporting ambulance stretcher equipment.

With the increase of emergencies and traumas in future naval battles and water system disasters, especially in modern wars, emergency transportation of the wounded, as an important part of medical rescue, is a process that connects whether the suddenly wounded can obtain comprehensive and effective treatment safely. important link.

It mainly includes multifunctional stretcher body 1, head cushion 2, head fixing device 3, handle 4, fixing strap 5, inflation/exhaust device, storage device 7, sea balance lifesaving tent 8, help-seeking auxiliary device, etc. Ancillary modules such as thermal insulation devices.

The stretcher body of the offshore floating lifesaving system has a relatively large buoyancy, which can realize the function of floating at sea, and through the auxiliary related accessories, the wounded can enter the system in a "horizontal" manner and quickly solidify the body shape, so that the wounded's condition will not be caused by repeated moving. And worse. This life-saving system is connected with the falling-in-the-sea rescue device by a rope. Rescuers find the wounded, bring the wounded to the stretcher, and send the wounded into the system, then pull up the rope of the falling-in-the-sea rescue device, and land the system and the wounded on the sea surface smoothly. Moreover, a rescue sling coated with fluorescent powder, such as a steel wire sling, is attached to the head and tail of the stretcher body 1 to facilitate rescuers to identify and rescue.

In order to further illustrate the technical solution of the present invention, it will be described below in conjunction with specific embodiments and accompanying drawings 1 to 8 .

As shown in Figure 1, the unfolded size (length, width and height) of the stretcher body 1: ≤200cm*120cm*12cm (preferred size is 200cm*100cm*10cm), net weight: ≤12kg, can bear the weight of more than 150 kilograms.

The stretcher body 1 is different from the traditional stretcher structure consisting of stretcher rods, stretcher surfaces, feet, and cross braces. The stretcher body 1 of the offshore floating lifesaving system is an inflatable structure formed in one piece. The stretcher body 1 is formed at one time by Robust welding. Avoid cracking and air leakage of the stretcher, and the integrated structure has high strength, easy to use and easy to maintain.

In order to make the floating lifesaving system have flame-resistant and anti-corrosion functions, the front and back surfaces of the stretcher body 1 are made of high-quality and light flame-retardant materials. Specifically, the front and back of the stretcher body 1 are made of high-quality PVC material, and the PVC material is modified by plasma treatment and post-finishing technologies, so that the material has properties such as flame retardancy, corrosion resistance, high strength, softness, lightness, and warmth retention. , to meet the needs of sea rescue. It can also be made of light-weight and high-strength composite materials such as modified thermoplastic polyurethane PU materials and aramid fiber 1414. Among them, thermoplastic polyurethane material, as an elastomer, is a material between rubber and plastic. It not only has the high elasticity of rubber, but also has the high hardness and high strength of plastic, and has excellent wear resistance, low temperature resistance and chemical resistance. Product corrosion and processing performance; Aramid 1414 has lyotropic liquid crystallinity due to the rigidity of the molecular chain, and it is easy to form anisotropic texture under the action of shear force in the solution. It also has high heat resistance and high strength. Stable in heat shrinkage and creep, in addition to high insulation and chemical resistance.

As shown in Figure 2, according to the characteristics of the vibration response of the human lying position, the present invention optimizes the structure of the stretcher vibration isolation system with the optimization mathematical method, thereby effectively improving the vibration and comfort of the stretcher. The outer contour airtight film of the inner core structure is shaped into a human lying position, filled with evenly foamed PS particles, and communicated with the inflation/exhaust port 62 of the stretcher body 1 through the inflatable nozzle on the outer contour airtight film. For inflating or pumping air. Specifically, through the negative pressure principle of the inner core structure, the positive shape structure can be cleverly designed to provide the body shaping function of the wounded.

The stretcher body 1 disclosed in the embodiment has an inner core structure that can form a negative pressure system by vacuuming, so that the front is an arc-shaped curved surface structure that adapts to the natural shape of the wounded when lying down, that is, it is the same as when the wounded is lying down. An immobilization pad that adapts to the body's natural curves. When the ship rescues or transports the wounded, when the wounded is lying on a stretcher, the wounded needs to be quickly fixed according to his body shape, avoiding slipping, rotation and vibration, so that the wounded can be effectively fixed, and the relative movement of different parts of the body is reduced, greatly reducing the The suffering of the wounded during transport. At the same time, the material selected for the inner core structure also has a certain degree of elasticity, so that the stretcher has a vibration-damping effect.

The inner core structure can be made of polystyrene, which is a light-duty high molecular weight polymer. Polystyrene resin is used to add a foaming agent, while heating to soften and generate gas to form a foam with a rigid closed-cell structure. Polystyrene has a uniform and closed cavity structure, which makes it have the characteristics of low water absorption, good heat preservation, light weight and high mechanical strength.

As can be seen from Fig. 2, the back of the stretcher body 1 is an arc-shaped curved surface structure, and the radius of its arc-shaped surface is smaller than the radius of the front arc-shaped surface, and it is ensured that the overall center of gravity of the stretcher is basically coincident with the center of gravity of the stretcher itself after the load is added, so that the buoyancy and The moments generated by gravity all point to the positive floating position, so as to realize the overall self-balancing. As shown in Figure 3, according to the principle of stable balance of the floating body, the floating body is in a stable and balanced state when the center of gravity of the floating body is higher than the center of gravity of the floating body. After loading, the overall center of gravity is located at the exact center of the stretcher, ensuring that the life-saving system can float stably and make it have a self-balancing function. Specifically, the three-dimensional model of the stretcher can be established by the computer, and the buoyancy and moment of inertia of the stretcher can be deduced, so as to design the arc-shaped bottom shape of the stretcher to ensure that the center of gravity of the stretcher is located at the center of gravity of the human body, so that the moments generated by buoyancy and gravity point to the upright floating position. Thereby, the anti-turnover floating function of the stretcher is realized, and the effect of double insurance is played.

As shown in FIG. 1 and FIG. 4 , the stretcher body 1 is equipped with a head pad 2 and a head fixing device 3 . The head cushion 2 is used to increase the comfort of the wounded head, and raise the wounded head to increase safety when using on water. The head immobilization device 3 is mainly used for fixing the head of the wounded with head and neck fractures. Four symmetrical headrest fixing holes 11 are arranged in the middle of the front part of the stretcher body 1 , which can be used to position the headrest 2 and install the headrest device 3 . There is a foot hole 12 in the middle of the stretcher rear, which can be used to fix the wounded's feet. There is a crotch hole 13 in the middle part of the stretcher, which can be used to fix the crotch of the wounded. The stretcher body 1 is equipped with three sets of fixing straps 5 located at the front, middle and rear positions, which are used to securely fix the wounded on the floating stretcher. The length of fixing tether 5 can be freely adjusted according to the build of the wounded.

In order to quickly transfer the wounded, there are 3 pairs of holes around the stretcher, which are mainly used as handles 4 for grasping when carrying the wounded and sick. In addition, consider moving the wounded under special environments such as smooth ground, stairwell, narrow space, design antiskid tricycle 14 on the back side both sides of stretcher, just carry with single person. It is worth noting that the handle 4, the headrest fixing hole 11, the foot hole 12 and the crotch hole 13 etc. are all formed when the stretcher body 1 is formed at one time.

The head, the middle part and the afterbody of the bottom surface of the stretcher body 1 are respectively equipped with super-large suction cups to ensure that the stretcher body 1 is firmly adsorbed on the smooth surface of the submarine to prevent slipping.

The marine lifesaving system becomes hard when it is vacuumed and shaped, and becomes soft and shrinkable after being inflated and restored). The system has the function of fast inflation, and the inflation method is divided into cylinder inflation and air pump inflation. As shown in Figure 6, in the embodiment, the inflation/extraction device of the marine floating lifesaving system includes: a detachable gas cylinder 61 is provided on the side near the front of the stretcher body 1, which can be pulled directly in an emergency The gas cylinder 61 is formed within 1 minute; the pedal charging/exhausting port 62 arranged on the side of the stretcher body 1 near the rear can quickly and easily pump air through the foot pump 63, and the air pump is formed within 2 minutes.

Under the condition of ensuring flotation, the offshore floating lifesaving system can also be equipped with a waterproof isolation shield with positive buoyancy balance function. As shown in Fig. 7, in the embodiment, a retractable and foldable balance rescue tent 8 is added to the system by using the spring principle, referred to as the tent 8, and the top of the tent 8 is marked with an eye-catching color to facilitate the identification of ambulance ships and aircraft. The length and width of the tent 8 are basically consistent with the stretcher body 1, and one end of the tent 8 is connected to the tail of the stretcher body 1. During use, the tent 8 is unfolded and the other end is fixed to the head. Increase this retractable waterproof tent 8, avoid the wounded from choking water, prevent the impact of waves from affecting the normal breathing of the wounded carried by the stretcher and seawater erosion from causing wound infection, and simultaneously play a warming effect on the wounded. Due to the necessary life support measures, the system can be used exclusively to rescue the wounded who fell into the sea.

Based on the analysis of the movement of the transporter and the wounded, from the perspective of maneuverability, convenience and safety, the location of the help-seeking auxiliary device is further designed for the system, so as to quickly find the wounded and ensure fast and efficient rescue. Such as LED lighting 91, marine rapid positioning module 92, marine life support device, rescue sling, etc.

The waterproof LED lighting lamp 91 commonly used in the aid-seeking aid, the rapid positioning module at sea and the life support module can be fixed on both sides of the stretcher. Among them, the maritime rapid positioning module 92 can integrate: 1) Beidou/GPS double-star message maritime wireless positioning technology; 2) ultra-short wave maritime search wireless communication positioning technology, without satellites and base stations; 3) combined rescue technology of beacons, lighting reflections, and signal bombs ; To accurately and quickly locate the position of the marine lifesaving system. Marine life support devices can be integrated: 1) Drinking water and micro (nano) seawater purification devices/miniature solar distilled water circulation devices; 2) Vital signs monitoring and emergency rescue equipment (hemostasis, disinfectants and antibacterial drugs, etc.); 3) Miniature high performance power supply or tiny solar powered (foldable) devices, etc. In order to facilitate air rescue, the offshore floating lifesaving system is also equipped with at least one pair of rescue slings.

As shown in Fig. 8, the marine floating lifesaving system also has a storage function, and a storage device 7, namely a storage bag, can be configured. What the stretcher body 1 adopted is high-quality and light heat-preserving flame-retardant material, and the stretcher hardens when fixing the wounded, and the stretcher becomes soft and just easy to roll when folding. The stretcher body 1 can design the most convenient roll-up method according to the special environmental requirements of ship equipment and sea rescue, test its size and portability, and optimize the best folding structure to facilitate storage, transportation, deployment, and quick use.

In addition, a rewarming and heat preservation device is further designed for the system to provide rewarming and heat preservation functions for the wounded floating at sea. A (physical or chemical) heating insulation layer is designed inside the stretcher body 1, and the heating element or heating material is used to ensure that the stretcher is always in a warm state, so that the wounded lying on the stretcher will not be injured again or be frozen to death.

The system integrates various life-saving functions, and can be directly associated with rescue objects/ships and shipboard personnel. It provides a ship system interconnection interface and is installed on ships. It can safely slide down to the sea to escape or transfer during emergency rescue. The system can also be used as a floating rescue cabin, and slides or inflatable channel devices are also equipped to ensure automatic sliding in case of distress. In addition, it can also be connected to the ship's rescue channel through the deck, so that the medical staff can arrange the escape and transfer of the wounded and sick.

Based on this offshore floating lifesaving system, the wounded can be sent into the system in a horizontal manner. The specific implementation process is as follows: first, the stretcher body 1 is unfolded to ensure that the particles inside the vacuum stretcher are evenly distributed; The trachea of the air cylinder 63 is connected to the pedal filling/pumping port 62 of the vacuum stretcher, the knob switch on the pedal filling/pumping port 62 is turned on (i.e., rotated counterclockwise), and then the foot pump 63 is used to pump the vacuum stretcher. According to the needs of the actual situation, adjust the hardness of the vacuum stretcher, and under the appropriate hardness, turn off the knob switch (i.e. rotate clockwise) to disconnect the trachea of the beriberi cylinder 63; use the fixed strap 5 to fix the wounded , the medical staff can use the handle to transfer the wounded; after use, turn on the knob switch of the pedal charging/suction port 62, make the vacuum stretcher body 1 soften, then close the knob switch, and then fold and store.

It can be seen from the above that through the floating life-saving system at sea, after the rescuers send the wounded into the system, they can land the wounded on the sea surface without personally escorting them. The rescuers can quickly implement the next rescue according to the instructions of the ship, so as to improve the efficiency of ship (ship) rescue as much as possible.
