Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphene heating technology, and more specifically, to a flexible graphene heating pad for operating tables. Background Technology
[0002] It is well known that operating rooms, whether in specialized or general hospitals, are often closely associated with the word "cold." This is because, on the one hand, operating room temperature control is crucial to inhibit bacterial growth and reduce the risk of surgical site infection; on the other hand, operating rooms are equipped with numerous high-precision medical devices that require strict temperature control. Excessive heat can lead to decreased or damaged equipment performance, thus affecting the smooth progress of the surgery. However, patients who are fasting and have their surgical sites exposed often feel extremely cold in the operating room. Studies have shown that using medical warming blankets to pre-warm the patient before anesthesia is an effective way to maintain normal body temperature, and the longer the pre-warming time, the better it is for maintaining the patient's body temperature and improving comfort. Therefore, during surgery, various warming devices are used to maintain the patient's body temperature, such as placing medical warming blankets on the operating table to provide a safe and comfortable environment.
[0003] Currently, most medical heating blankets on the market use electric heating wires, which has many drawbacks such as electric leakage, burns, slow heating speed, and uneven temperature. In addition, the blanket-style structure of medical heating blankets is not easy to store and affects portability. Furthermore, most medical heating blankets achieve preheating through surface contact, resulting in a limited functionality.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] See also Figures 1-3This utility model provides a flexible graphene heating pad for operating tables, including a medical skin-friendly structure 1, a graphene heating component 2, a heat-conducting cylinder 3, and a medical skin-friendly structure 4.
[0026] In this embodiment: the medical skin-friendly structure-1 includes a skin-friendly contact layer-11, and the surface of the skin-friendly contact layer-11 is coated with an antibacterial layer-12.
[0027] The skin-friendly contact layer 11 can be made of skin-friendly materials such as skin-friendly fibers and soft TPU film. The skin-friendly fibers and soft TPU film meet the advantages of skin-friendliness and breathability when in contact with the skin. In order to meet the needs of disassembly and assembly of graphene heating component 2, the skin-friendly contact layer 11 should be made into a bag structure for filling. The antibacterial agent of antibacterial layer 12 includes at least one of chitosan antibacterial agent and silver ion antibacterial agent. This can make the skin-friendly contact layer 11 have reliable antibacterial and skin-friendly effects when in contact with the skin.
[0028] In this embodiment, a zipper 6 is provided at one end of the skin-friendly contact layer 11.
[0029] One end of the skin-friendly contact layer 11 has an opening, and the zipper 6 can easily control the opening of the skin-friendly contact layer 11 to open and close, which makes it easy to disassemble and assemble the graphene heating component 2.
[0030] In this embodiment: the graphene heating component 2 includes an electrical connection wire 21, one end of which is provided with a graphene heating element 22. A temperature control switch 23 and a power supply connector 24 are provided on the electrical connection wire 21. The graphene heating element 22 is disposed in the skin-friendly contact layer 11. The graphene heating element 22 includes a graphene layer 221. An upper flexible film layer 222 and a lower flexible film layer 223 are respectively provided above and below the graphene layer 221. The peripheral side of the graphene layer 221 is coated with conductive silver paste 7. The conductive silver paste 7 is hot-pressed and sealed on the upper flexible film layer 222 and the lower flexible film layer 223.
[0031] The graphene heating pad 22 heats up rapidly and evenly, providing a warm and comfortable environment for the patient. The upper flexible film layer 222 and the lower flexible film layer 223 are combined on the graphene heating pad 22 and can be easily folded for easy storage. The upper flexible film layer 222 and the lower flexible film layer 223 are made of polyethylene terephthalate, silicone, or thermoplastic polyurethane elastomer. The power connector 24 supports two-prong plugs, USB connectors, Micro USB and Type C connectors, with strong adaptability. The thickness of the upper flexible film layer 222 and the lower flexible film layer 223 is 1mm-100mm. The length of the graphene heating pad 22 is 80-100cm and the width is 35-45cm, which fits the size of the operating table.
[0032] A temperature sensing probe can be installed on the graphene heating element 22 in this application. The temperature sensing probe can be electrically connected to the electrical connection line 21 through the overheat protector. The temperature setting range of the temperature control switch 23 is 20-40 degrees. It can meet the overheat protection function when the temperature is higher or lower than the set temperature. Since the temperature sensing probe and the overheat protector are both general standard parts or components known to those skilled in the art, their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0033] In this embodiment, a storage opening 8 is provided on the heat-conducting cylinder 3.
[0034] The storage port 8 allows for easy introduction of the medical skin-friendly structure 1 and the graphene heating element 2 embedded in the medical skin-friendly structure 1 into the heat-conducting cylinder 3. This facilitates the roll-up storage of the medical skin-friendly structure 1 and the graphene heating element 2. The heat-conducting cylinder 3 can be made of either PPS or PA46 plastic, which gives it high strength and thermal conductivity. When the graphene heating element 22 is used for heating inside the heat-conducting cylinder 3, it achieves a cylindrical heating effect. The heat-conducting cylinder 3 transfers heat to the skin-friendly contact layer 41 through thermal conduction. This allows for heat therapy on the human body at the location of the skin-friendly contact layer 41. This method of use can be applied to the lumbar and cervical spine to achieve therapeutic effects.
[0035] In this embodiment: the second medical skin-friendly structure 4 is disposed on the heat-conducting cylinder 3. The second medical skin-friendly structure 4 includes a second skin-friendly contact layer 41, which is sleeved on the outside of the heat-conducting cylinder 3. The surface of the second skin-friendly contact layer 41 is coated with an antibacterial layer 42.
[0036] The second skin-friendly contact layer 41 is also made of skin-friendly materials such as skin-friendly fibers and soft TPU film. The skin-friendly fibers and soft TPU film mentioned above all meet the advantages of skin-friendliness and breathability in skin contact. In order to meet the requirements of the second skin-friendly contact layer 41 being fitted on the heat-conducting cylinder 3, the second skin-friendly contact layer 41 should be made into a cylindrical structure. The antibacterial factors of the second antibacterial layer 42 also include at least one of chitosan antibacterial agent and silver ion antibacterial agent. This can make the heat-conducting cylinder 3 have reliable antibacterial and skin-friendly effects when in contact with the skin.
[0037] In this embodiment: the heat-conducting cylinder 3 is provided with a winding structure 5 for winding up the medical skin-friendly structure 1. The winding structure 5 includes a tray 51, which is rotatably connected to the inner bottom of the heat-conducting cylinder 3. A roller rod 52 is fixedly connected to the tray 51. One end of the roller rod 52 facing away from the tray 51 is damped and rotatably connected to the inner top of the heat-conducting cylinder 3. One end of the roller rod 52 is fixedly connected to a torsion block 53, which is located on the outer side of the heat-conducting cylinder 3.
[0038] When the skin-friendly contact layer 11 needs to be rolled up inside the heat-conducting cylinder 3, the roller rod 52 can be rotated by the twist block 53. In this way, the roller rod 52 can drive the skin-friendly contact layer 11 through the storage opening 8 and into the heat-conducting cylinder 3 through the traction belt 9, so that the skin-friendly contact layer 11 can roll up the graphene heating sheet 22 inside and place it on the tray 51. This allows for quick storage of the graphene heating sheet 22 and makes it convenient to carry.
[0039] In this embodiment: a traction belt 9 is fixedly connected to the roller rod 52, one end of the traction belt 9 passes through the storage opening 8, and Velcro 91 is provided on the traction belt 9 and the skin-friendly contact layer 11.
[0040] The traction strap 9 can be bonded and fixed to the skin-friendly contact layer 11 by the corresponding Velcro 91. When the skin-friendly contact layer 11 needs to be removed for cleaning, the Velcro 91 can be removed. When the skin-friendly contact layer 11 needs to be rolled up in the heat-conducting cylinder 3, the Velcro 91 can be bonded.
[0041] In this embodiment, a winding post 10 is provided at one end of the heat-conducting cylinder 3.
[0042] Multiple winding posts 10 can be set. Since the graphene heating component 2 includes an electrical connection wire 21, the winding posts 10 can be set to conveniently wind the electrical connection wire 21 to shorten the free length, which makes it easier for the heat-conducting cylinder 3 to carry the entire graphene heating component 2.
