Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] As shown in Figure 1 to Figure 5 As shown, this embodiment provides a rescue sleeping bag that, while ensuring the injured person's body temperature can rise rapidly, reduces the chance of the injured person being infected inside the rescue sleeping bag, improves the convenience of outdoor medical rescue, and also reduces the rate of body temperature loss of the injured person during the rescue process.

[0041] See Figure 1A and Figure 2 The rescue sleeping bag includes a zipper 1, a front sleeping bag panel 2, and a back sleeping bag panel 3. Both the front sleeping bag panel 2 and the back sleeping bag panel 3 include an antibacterial layer 21, a heating layer 22, and a protective layer 23. The antibacterial layers 21 of the front sleeping bag panel 2 and the back sleeping bag panel 3 form a sleeping space 4. The heating layer 22 is located between the antibacterial layer 21 and the protective layer 23 and is used to heat the sleeping space 4. The protective layer 23 is used to prevent moisture and wind from entering the sleeping space 4. The zipper 1 extends circumferentially along the front sleeping bag panel 2. The front sleeping bag panel 2 is detachably connected to the back sleeping bag panel 3 through the zipper 1. The zipper 1 is provided with multiple movable pull heads 11 along its extension direction. Driving the pull heads 11 to move allows the front sleeping bag panel 2 and the back sleeping bag panel 3 to separate at least partially.

[0042] The rescue sleeping bag provided in this embodiment has a sleeping space 4 formed by an antibacterial layer 21. When the injured person enters the sleeping space 4, the antibacterial layer 21 can prevent bacteria from entering the sleeping space 4, effectively avoiding bacterial growth within the sleeping space 4 and reducing the chance of infection. The heating layer 22 can provide heat to the sleeping space 4, allowing the body temperature of the injured person inside the sleeping space 4 to rise rapidly, buying valuable time for subsequent treatment. The protective layer 23 can block moisture and wind from entering the sleeping space 4, keeping the interior of the sleeping space 4 dry and warm, improving the comfort and safety of the injured person inside the sleeping space 4. The zipper 1 allows the front panel 2 of the sleeping bag to be connected to and separated from the back panel 3. When the front panel 2 and the back panel 3 are fully connected, the sleeping space 4 is sealed, effectively preventing heat loss. When the front panel 2 and the back panel 3 are at least partially separated, medical personnel can examine the injured person in the sleeping space 4 through the separated portion, improving the convenience of outdoor medical rescue. Furthermore, the zipper pull 11 can move along the extension direction of the zipper 1, allowing the front panel 2 to be separated from the back panel 3 at any position along its circumference. This enables medical personnel to treat different body parts of the injured person, such as the head, waist, or feet, without having to completely close the entire rescue sleeping bag, effectively reducing the rate of heat loss during rescue and ensuring the life and health of the injured person.

[0043] For example, the antibacterial layer 21 is made of graphene. Graphene is a two-dimensional material composed of a single layer of carbon atoms arranged in a hexagonal lattice, possessing extremely high specific surface area and excellent electrical and thermal conductivity, as well as nanoknife effects. When bacteria come into contact with the graphene surface, the high chemical activity of graphene interacts with the bacterial cell wall or cell membrane, leading to bacterial destruction and death; the nanoknife effect of graphene can rupture the bacterial cell membrane, causing the cell contents to leak out, thereby killing the bacteria. Moreover, graphene is non-toxic and harmless to the human body and can be in direct contact with the human body.

[0044] Optionally, see Figure 1B and Figure 2 The heating layer 22 includes an electric heating layer 221 and two insulating layers 222, which are disposed on both sides of the electric heating layer 221. The electric heating layer 221 is configured to convert electrical energy into heat energy to quickly provide a large amount of heat to the sleeping space 4. The insulating layers 222 have insulating properties, ensuring user safety during the heating process of the electric heating layer 221; moreover, the insulating layers 222 can also block heat transfer towards the protective layer 23, reducing the rate of heat loss from the sleeping space 4. Heating the sleeping space 4 with electricity does not produce any pollutants, smoke, or noise, meeting the requirements of outdoor environmental protection.

[0045] For example, the insulating layer 222 is typically made of a high-temperature resistant and aging-resistant insulating material, such as polyester film or polyimide film. These materials have good electrical insulation properties and mechanical strength, and can effectively protect the heating layer 221 from the influence of the external environment.

[0046] In this embodiment, see Figure 1A , Figure 2 and Figure 3 The front panel 2 and / or rear panel 3 of the sleeping bag are provided with a power supply or external power port. The heating layer 22 also includes a wire. The electric heating layer 221 includes multiple electric heating elements 2211, which are arranged along the length of the rescue sleeping bag. Figure 3 The X direction in the middle) and / or the width direction of the rescue sleeping bag ( Figure 3The heating elements 2211 are arranged at intervals in the Y direction. They are detachably connected to the insulation layer 222 and electrically connected to a power source or an external power port via wires. An external power source can provide power to the rescue sleeping bag through the external power port. The wires can transmit the power provided by the power source or external power source to the heating elements 2211. The heating elements 2211 generate resistance, converting electrical energy into heat energy, and the surface temperature of the heating elements 2211 rises, thus heating the sleeping space 4. The arrangement of multiple heating elements 2211 allows the heating layer 221 to have multiple heating areas, so that the injured person in the sleeping space 4 can be evenly heated, which helps the injured person's body temperature to rise. The heating elements 2211 are detachably connected to the insulation layer 222. When the rescue sleeping bag needs to be cleaned, the user can remove the heating elements 2211, ensuring the service life of the heating layer 22.

[0047] For example, the power source is a battery, and the external power source is a power bank. The power bank is connected to the wire through an external power port, which increases the convenience of using the rescue sleeping bag. Both the front panel 2 and the back panel 3 of the sleeping bag are provided with battery or external power ports to prevent the separation of the front panel 2 and the back panel 3 from affecting the heating layer 22.

[0048] Further, see Figure 1B , Figure 2 and Figure 3 The heating layer 221 of the front panel 2 and the heating layer 221 of the back panel 3 of the sleeping bag each include three heating elements 2211, which are arranged along the length of the sleeping bag. Figure 3 The sleeping bag is spaced in the X direction. The three electric heating pads 2211 on the front panel 2 of the sleeping bag correspond to the chest, abdomen and feet of the injured person, respectively. The three electric heating pads 2211 on the back panel 3 of the sleeping bag correspond to the back, buttocks and feet of the injured person, respectively, so that the injured person in the sleeping space 4 can be heated evenly.

[0049] In other embodiments, the electrothermal layer 221 is an electrothermal film, which is electrically connected to a power source or an external power supply via wires. The electrothermal film is typically formed by printing a special conductive ink onto an insulating polyester film. The conductive ink contains carbon molecules or other conductive materials. Under the influence of an electric field, the carbon molecules undergo Brownian motion, resulting in intense friction and collisions between them, thereby generating heat. This heat is transferred to the sleeping space 4 in the form of far-infrared radiation and convection, thus heating the sleeping space 4.

[0050] For example, the heating layer 22 is entirely made of a low-power electrothermal film. While providing the same amount of heat, the low-power electrothermal film consumes less electrical energy. Furthermore, the film can maintain the sleeping space 4 at a constant temperature, avoiding energy waste and making it more suitable for use in harsh conditions. In addition, the low-power electrothermal film also features high temperature resistance, good flexibility, strong current carrying capacity, and strong oxidation resistance, making it even more suitable for use in rescue sleeping bags.

[0051] Further, see Figure 2 , Figure 3 and Figure 5 The front panel 2 and / or rear panel 3 of the sleeping bag are equipped with adjustable thermostats 24. The thermostat 24 is electrically connected to the heating layer 221 and is used to control the heat output of the heating layer 221. When the temperature inside the sleeping space 4 is low, the heat output of the heating layer 221 can be increased by adjusting the thermostat 24, so that the heating layer 221 can generate heat quickly and help the injured person's body temperature rise rapidly. When the temperature inside the sleeping space 4 is too high, the heat output of the heating layer 221 can be reduced by adjusting the thermostat 24 to prevent the heating layer 221 from overheating and causing a safety accident.

[0052] For example, both the front and back sleeping pads are equipped with thermostats 24 to precisely control the corresponding heating layers 22; the thermostats 24 are temperature controllers commonly used in electric blankets and have three settings.

[0053] Optionally, see Figure 1A and Figure 2 Between the antibacterial layer 21 and the heating layer 22, a heat-insulating layer 25 is also provided. The heat-insulating layer 25 is a network structure made of hollow fibers and microfibers, used to prevent heat from the sleeping space 4 from being transferred outwards. Hollow fibers are chemical fibers with tubular cavities running through the fiber axis. The tubular cavities can effectively lock in still air, achieving high-efficiency heat retention for the heat-insulating layer 25. The special structure of hollow fibers also gives the heat-insulating layer 25 excellent thermal conductivity, allowing the heat generated by the heating layer 22 to be efficiently transferred to the sleeping space 4, reducing heat loss. Microfibers have extremely small diameters, and the composite network structure formed by them and hollow fibers has tiny pores. These tiny pores facilitate the flow of air and moisture, giving the heat-insulating layer good moisture absorption and breathability, reducing the stuffiness of the injured person and improving comfort during use. Moreover, the network structure formed by the interweaving or composite of hollow fibers and microfibers can also significantly enhance the stability and durability of the heat-insulating layer, preventing damage to the structure of the heat-insulating layer 25 during cleaning.

[0054] Optionally, see Figure 1C and Figure 1DWhen the front piece 2 and the back piece 3 of the sleeping bag are connected, an opening 5 is formed on the rescue sleeping bag. The opening 5 is connected to the sleeping space 4, and the diameter of the opening 5 is adjustable. The injured person's head can be extended out of the sleeping space 4 through the opening 5 to ensure the injured person's normal breathing. By adjusting the diameter of the opening 5, the diameter of the opening 5 can be adapted to the circumference of the injured person's head to prevent cold air from entering the sleeping space 4 through the opening 5.

[0055] In this embodiment, see Figure 1E and Figure 1F The rescue sleeping bag also includes a drawstring 51, which is located at the opening 5 and extends circumferentially along the opening 5. Pulling the drawstring 51 changes the diameter of the opening 5.

[0056] Optionally, see Figure 1B The zipper 1 includes a first tooth 12 and a second tooth 13 adapted to the first tooth 12. The first tooth 12 is located on the front panel 2 of the sleeping bag, and the second tooth 13 is located on the back panel 3 of the sleeping bag. Multiple zipper pulls 11 are movably mounted on either the first tooth 12 or the second tooth 13. By moving the zipper pull 11, the first tooth 12 can engage or disengage with the second tooth 13, enabling quick connection and separation of the front panel 2 and the back panel 3 of the sleeping bag.

[0057] Optionally, the rescue sleeping bag also includes a temperature sensor and an alarm device located on the front panel 2 and / or the rear panel 3 of the sleeping bag. The temperature sensor and the alarm device are electrically connected, and the temperature sensor is used to monitor the temperature of the sleeping space 4. When the temperature inside the sleeping space 4 becomes too high, the alarm device can remind the injured person to adjust the temperature of the heating layer 22.

[0058] For example, the temperature sensing element is a thermometer, and the alarm element is a buzzer.

[0059] Optionally, see Figure 2 The protective layer 23 includes a waterproof layer 231 and a windproof layer 232. The windproof layer 232 is located between the waterproof layer 231 and the heating layer 22. The waterproof layer 231 is made of a breathable waterproof membrane, and the windproof layer 232 is made of aerogel material. A breathable waterproof membrane is a functional membrane manufactured using a special process. Its structure typically includes micropores or a special waterproof and breathable layer, which can prevent moisture penetration while allowing gas molecules to pass through, thus providing excellent breathability and comfort while maintaining waterproof performance. Aerogel is a nanoscale porous solid material formed by replacing the liquid phase in the gel with gas through a specific drying method. Because the pore size of aerogel is typically smaller than the mean free path of air molecules, air molecules are hindered when passing through the aerogel, thereby slowing down wind speed and achieving a windproof effect.

[0060] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
