[0001] The present invention relates to the technical field of medical rescue, and particularly to a rescue sleeping bag. Background Art

[0002] A rescue sleeping bag is a rescue equipment designed specifically for dealing with harsh environments such as cold and humidity. It has excellent warmth retention, moisture resistance and portability, and is an essential important equipment in rescue sites, outdoor camping and exploration activities. In a harsh environment, a rescue sleeping bag can not only provide a reliable shelter space for the injured, but also help the injured recover body temperature in a very short time, thus winning precious time for subsequent treatment.

[0003] Most existing rescue sleeping bags are provided with zippers to facilitate users to enter the interior of the rescue sleeping bag, and when the zipper is closed, it can also ensure the sealing and warmth retention of the interior of the rescue sleeping bag to prevent heat dissipation and the entry of external cold air. However, most of the zippers of existing rescue sleeping bags are arranged longitudinally along the length of the rescue sleeping bag, so that medical staff need to unzip the entire rescue sleeping bag when checking the body of the injured, resulting in rapid heat dissipation of the injured during the treatment process, which is not conducive to the development of outdoor treatment. In addition, the inner lining fabrics of existing rescue sleeping bags generally lack antibacterial functions, which not only increases the risk of wound infection of the injured, but also may pose a potential threat to their life and health.

[0004] Therefore, there is an urgent need for a rescue sleeping bag to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a rescue sleeping bag, which can reduce the probability of the injured being infected in the rescue sleeping bag, improve the convenience of outdoor medical rescue, and also reduce the rate of heat dissipation of the injured during the rescue process on the premise of ensuring that the body temperature of the injured can rise rapidly.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0010] The electric heating layer includes a plurality of electric heating sheets, and the plurality of electric heating sheets are arranged at intervals along the length direction and / or the width direction of the rescue sleeping bag. The electric heating sheets are detachably connected to the insulating layer and are electrically connected to the power source or the external power port through wires;

[0011] Alternatively, the electric heating layer adopts an electric heating film, and the electric heating film is electrically connected to the power source or the external power port through a wire.

[0012] Optionally, a temperature controller with adjustable gears is further provided on the front piece and / or the back piece of the sleeping bag. The temperature controller is electrically connected to the electric heating layer and is used to control the heat supply of the electric heating layer.

[0013] Optionally, a heat preservation layer is further provided between the antibacterial layer and the heating layer. The heat preservation layer is a network structure made of hollow fibers and superfine fibers and is used to block the heat in the sleeping space from being transferred outwards.

[0014] Optionally, when the front piece of the sleeping bag is connected to the back piece of the sleeping bag, an opening is formed on the rescue sleeping bag. The opening is communicated with the sleeping space, and the diameter of the opening is adjustable.

[0015] Optionally, the rescue sleeping bag further includes a drawstring. The drawstring is arranged at the opening and extends along the circumference of the opening.

[0016] Optionally, the zipper includes a first row of teeth and a second row of teeth adapted to the first row of teeth. The first row of teeth is arranged on the front piece of the sleeping bag, and the second row of teeth is arranged on the back piece of the sleeping bag. A plurality of sliders are all movably arranged on the first row of teeth or the second row of teeth.

[0017] Optionally, the rescue sleeping bag further includes a temperature sensing element and an alarm element arranged on the front piece and / or the back piece of the sleeping bag. The temperature sensing element is electrically connected to the alarm element, and the temperature sensing element is used to monitor the temperature of the sleeping space.

Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] As shown in FIGS. 1 to Figure 5 shown, this embodiment provides a rescue sleeping bag, which reduces the probability of the injured being infected in the rescue sleeping bag, improves the convenience of outdoor medical rescue, and also reduces the rate of heat loss of the injured during the rescue process on the premise of ensuring that the body temperature of the injured can rise rapidly.

[0042] Referring to Figure 1A and Figure 2 , the rescue sleeping bag includes a zipper 1, a front sleeping bag piece 2 and a rear sleeping bag piece 3. Both the front sleeping bag piece 2 and the rear sleeping bag piece 3 include an antibacterial layer 21, a heating layer 22 and a protective layer 23. The antibacterial layers 21 of the front sleeping bag piece 2 and the rear sleeping bag piece 3 enclose to 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 supply heat to the sleeping space 4. The protective layer 23 is used to block water vapor and wind from entering the sleeping space 4; the zipper 1 extends along the circumference of the front sleeping bag piece 2. The front sleeping bag piece 2 is detachably connected to the rear sleeping bag piece 3 through the zipper 1. A plurality of sliders 11 movable along its extending direction are arranged on the zipper 1. By driving the sliders 11 to move, the front sleeping bag piece 2 and the rear sleeping bag piece 3 are at least partially separated.

[0043] The rescue sleeping bag provided in this embodiment has a sleeping space 4 surrounded by an antibacterial layer 21. After the injured person enters the sleeping space 4, the antibacterial layer 21 can prevent bacteria from entering the sleeping space 4, effectively avoiding the growth of bacteria in the sleeping space 4 and reducing the probability of the injured person being infected. The heating layer 22 can supply heat to the sleeping space 4, enabling the body temperature of the injured person in the sleeping space 4 to rise rapidly, thus gaining valuable time for subsequent treatment; the provision of the protective layer 23 can block water vapor and wind from entering the sleeping space 4, keeping the interior of the sleeping space 4 dry and warm, and improving the comfort and safety of the injured person in the sleeping space 4. The setting of the zipper 1 enables the front piece 2 of the sleeping bag to be connected to and separated from the rear piece 3 of the sleeping bag. When the front piece 2 of the sleeping bag is fully connected to the rear piece 3 of the sleeping bag, the sealing performance of the sleeping space 4 can be ensured, effectively preventing the loss of heat in the sleeping space 4; when the front piece 2 of the sleeping bag is at least partially separated from the rear piece 3 of the sleeping bag, medical staff can check the injured person in the sleeping space 4 through the separated part between the front piece 2 and the rear piece 3 of the sleeping bag, improving the convenience of outdoor medical rescue; moreover, the slider 11 can move along the extending direction of the zipper 1, enabling the front piece 2 of the sleeping bag to be separated from the rear piece 3 at any position along its circumference, and thus medical staff can treat different body parts of the injured person such as the head, waist or feet, without having to fully unzip the entire rescue sleeping bag, effectively reducing the rate of heat loss of the injured person during the rescue process and ensuring the life and health of the injured person.

[0044] Exemplarily, 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, with ultra-high specific surface area and excellent electrical conductivity, thermal conductivity, nano-knife effect and other properties. When bacteria come into contact with the surface of graphene, the high chemical activity of graphene will act on the cell wall or cell membrane of the bacteria, resulting in the destruction and death of the bacteria; the nano-knife effect of graphene can cut through the bacterial cell membrane, causing the outflow of cell contents, 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.

[0045] Optionally, referring to Figure 1B and Figure 2 , the heating layer 22 includes an electrothermal layer 221 and two insulating layers 222. The two insulating layers 222 are respectively arranged on both sides of the electrothermal layer 221. The electrothermal layer 221 is configured to convert electrical energy into heat energy to quickly provide a large amount of heat for the sleeping space 4. The insulating layer 222 has the property of insulation, which can ensure the safety of users during the heat supply process of the electrothermal layer 221; moreover, the insulating layer 222 can also block the transfer of heat towards the protective layer 23 direction, reducing the rate of heat loss in the sleeping space 4. Heating the sleeping space 4 by electrical energy does not produce any pollutants, nor does it produce soot and noise, meeting the requirements of outdoor environmental protection.

[0046] Exemplarily, the insulating layer 222 is usually made of insulating materials that are resistant to high temperatures and aging, such as polyester films, polyimide films, etc. These materials have good electrical insulation properties and mechanical strength, and can effectively protect the electrothermal layer 221 from the influence of the external environment.

[0047] In this embodiment, referring to Figure 1A , Figure 2 and Figure 3 , a power source or an external power source port is provided on the front piece 2 of the sleeping bag and / or the rear piece 3 of the sleeping bag. The heating layer 22 further includes a wire. The electrothermal layer 221 includes a plurality of electric heating sheets 2211. The plurality of electric heating sheets 2211 are arranged at intervals along the length direction of the rescue sleeping bag ( Figure 3 the X direction in Figure 3 ) and / or the width direction of the rescue sleeping bag ( Figure 3 the Y direction in

[0048] ). The electric heating sheet 2211 is detachably connected to the insulating layer 222 and is electrically connected to the power source or the external power source port through a wire. The external power source can provide electrical energy for the rescue sleeping bag through the external power source port. The wire can transmit the electrical energy provided by the power source or the external power source to the electric heating sheet 2211. A resistance is generated inside the electric heating sheet 2211, and the electrical energy is converted into heat energy. The surface temperature of the electric heating sheet 2211 rises, realizing the heating of the sleeping space 4; the setting of the plurality of electric heating sheets 2211 enables the electrothermal layer 221 to have a plurality of heating regions, so that the whole body of the injured person located in the sleeping space 4 can be evenly heated, facilitating the recovery of the body temperature of the injured person; the electric heating sheet 2211 is detachably connected to the insulating layer 222. When the rescue sleeping bag needs to be cleaned, the user can detach the electric heating sheet 2211, ensuring the service life of the heating layer 22.

[0048] Exemplarily, the power source uses a battery, and the external power source uses a power bank. The power bank is connected to the wire through the external power source port, increasing the convenience of using the rescue sleeping bag. The battery or the external power source port is provided on both the front piece 2 of the sleeping bag and the rear piece 3 of the sleeping bag, avoiding the separation of the front piece 2 of the sleeping bag and the rear piece 3 of the sleeping bag from affecting the heating of the heating layer 22.

[0049] Furthermore, referring to Figure 1B , Figure 2 and Figure 3 , both the electrothermal layer 221 of the front piece 2 of the sleeping bag and the electrothermal layer 221 of the rear piece 3 of the sleeping bag include three electric heating sheets 2211. The three electric heating sheets 2211 are arranged at intervals along the length direction of the heating sleeping bag ( Figure 3 the X direction in

[0050] ). The positions of the three electric heating sheets 2211 on the front piece 2 of the sleeping bag correspond to the front chest, abdomen and feet of the injured person respectively, and the positions of the three electric heating sheets 2211 on the rear piece 3 of the sleeping bag correspond to the back, buttocks and feet of the injured person respectively, so that the whole body of the injured person located in the sleeping space 4 can be evenly heated.

[0050] In other embodiments, the electrothermal layer 221 is an electrothermal film, which is electrically connected to a power source or an external power port through a wire. The electrothermal film is usually formed by printing a special conductive ink on an insulating polyester film. The conductive ink contains carbon molecules or other conductive materials. Under the action of an electric field, the carbon molecules undergo "Brownian motion", that is, the carbon molecules collide and rub violently with each other, thereby generating heat energy. This heat energy is transferred to the sleeping space 4 in the form of far-infrared radiation and convection, realizing the heating of the sleeping space 4.

[0051] Exemplarily, the heating layer 22 as a whole adopts a low-power electrothermal film. Under the condition of providing the same amount of heat, the low-power electrothermal film consumes less electric energy. Moreover, the electrothermal film can also keep the sleeping space 4 at a constant temperature, avoiding waste of energy and being more suitable for use under harsh conditions. In addition, the low-power electrothermal film also has the characteristics of high temperature resistance, good flexibility, strong current-carrying capacity, strong oxidation resistance, etc., and is more suitable for rescue sleeping bags.

[0052] Furthermore, referring to Figure 2 , Figure 3 and Figure 5 , a thermostat 24 with adjustable gears is also provided on the front piece 2 and / or the rear piece 3 of the sleeping bag. The thermostat 24 is electrically connected to the electrothermal layer 221 and is used to control the heat supply of the electrothermal layer 221. When the temperature in the sleeping space 4 is relatively low, the heat supply of the electrothermal layer 221 can be increased by adjusting the gear of the thermostat 24, so that the electrothermal layer 221 can generate heat quickly and help the injured person's body temperature rise quickly; when the temperature in the sleeping space 4 is too high, the heat supply of the electrothermal layer 221 can be reduced by adjusting the gear of the thermostat 24 to prevent safety accidents caused by overheating of the electrothermal layer 221.

[0053] Exemplarily, thermostats 24 are provided on both the front piece and the rear piece of the sleeping bag to facilitate precise control of the corresponding heating layer 22; the thermostat 24 adopts a temperature controller mostly used on electric blankets and has three gears.

[0054] Optionally, referring to Figure 1A and Figure 2, a heat preservation layer 25 is further provided between the antibacterial layer 21 and the heating layer 22. The heat preservation layer 25 is a network structure made of hollow fibers and ultra-fine fibers, and is used to block the heat in the sleeping space 4 from being transferred outwards. The hollow fiber is a chemical fiber with a tubular cavity running through the fiber axis, and the tubular cavity can effectively lock the static air to achieve high-efficiency heat preservation of the heat preservation layer 25; the special structure of the hollow fiber also enables the heat preservation layer 25 to have excellent thermal conductivity, so that the heat generated by the heating layer 22 can be efficiently transferred into the sleeping space 4, reducing the heat loss. The diameter of the ultra-fine fiber is extremely small, and the composite network structure formed by it and the hollow fiber has tiny pores, which helps the circulation of air and moisture, makes the heat preservation layer have good moisture absorption and breathability, reduces the stuffy feeling of the injured, and improves the comfort during use; moreover, the network structure formed by the interweaving or compounding of the hollow fiber and the ultra-fine fiber can also significantly enhance the stability and durability of the heat preservation layer, and prevent the structure of the heat preservation layer 25 from being damaged during the cleaning process.

[0055] Optionally, referring to Figure 1C and Figure 1D , when the front piece 2 of the sleeping bag is connected to the rear piece 3 of the sleeping bag, an opening 5 is formed on the rescue sleeping bag. The opening 5 is communicated with the sleeping space 4, and the caliber of the opening 5 is adjustable. The head of the injured can extend out of the sleeping space 4 through the opening 5 to ensure the normal breathing of the injured; by adjusting the caliber of the opening 5, the caliber of the opening 5 is adapted to the head circumference of the injured to prevent cold air from entering the sleeping space 4 through the opening 5.

[0056] In this embodiment, referring to Figure 1E and Figure 1F , the rescue sleeping bag further includes a drawstring 51. The drawstring 51 is arranged at the opening 5 and extends along the circumference of the opening 5. By pulling the drawstring 51, the caliber of the opening 5 changes.

[0057] Optionally, referring to Figure 1B , the zipper 1 includes a first row of teeth 12 and a second row of teeth 13 adapted to the first row of teeth 12. The first row of teeth 12 is arranged on the front piece 2 of the sleeping bag, and the second row of teeth 13 is arranged on the rear piece 3 of the sleeping bag. A plurality of sliders 11 are all movably arranged on the first row of teeth 12 or the second row of teeth 13. By moving the slider 11, the first row of teeth 12 can be engaged with or separated from the second row of teeth 13, realizing the quick connection and separation of the front piece 2 and the rear piece 3 of the sleeping bag.

[0058] Optionally, the rescue sleeping bag further includes a temperature sensing element and an alarm element arranged on the front piece 2 and / or the rear piece 3 of the sleeping bag. The temperature sensing element is electrically connected to the alarm element, and the temperature sensing element is used to monitor the temperature of the sleeping space 4. When the temperature in the sleeping space 4 is too high, the alarm element can remind the injured to adjust the temperature of the heating layer 22.

[0059] Exemplarily, the temperature sensing element adopts a thermometer, and the alarm element adopts a buzzer.

[0060] Optionally, referring to 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 film, and the windproof layer 232 is made of an aerogel material. The breathable waterproof film is a functional film manufactured by a special process. Its structure usually includes micropores or a special waterproof and breathable layer, which can prevent water penetration while allowing gas molecules to pass through, that is, it can provide excellent breathability and comfort while maintaining waterproof performance. Aerogel is a nano-porous solid material formed by replacing the liquid phase in the gel with gas in a certain drying method. Since the pore size of aerogel is usually smaller than the mean free path of air molecules, air molecules are hindered when passing through aerogel, thus slowing down the wind speed and achieving the effect of wind prevention.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
