[0034] The utility model provides a heating mattress 100, which is intended to maintain a relatively balanced overall body temperature of a patient.

[0035] In the embodiment of the present utility model, in combination with reference to Figures 1 to 4 The heating mattress 100 includes a surface layer 10, a heating layer 20 and a power cord 50. A cavity 12 is provided inside the surface layer 10, and a lying surface 11 is provided on the outer side of the surface layer 10. The heating layer 20 is provided in the cavity 12, and the lying surface 11 is stacked on the heating layer 20 so that the heat of the heating layer 20 is evenly transferred to the lying surface 11. The power cord 50 passes through the surface layer 10 and is electrically connected to the heating layer 20.

[0036] It can be understood that the flat lying surface 11 on the outer side of the surface layer 10 is the side that the patient directly contacts with the heating mattress 100. The patient lies flat on the flat lying surface 11 as a whole. The heating layer 20 is located in the cavity 12 inside the surface layer 10. At the same time, the flat lying surface 11 is stacked on the heating layer 20, which is equivalent to the heating layer 20 being parallel to the flat lying surface 11. The shape and area of ​​the heating layer 20 are also the same as the shape and area of ​​the flat lying surface 11. After the power cord 50 is electrically connected to the heating layer 20, the heating layer 20 generates heat, and the heat generated can be evenly transferred to The lying surface 11, that is, any position of the lying surface 11, can absorb heat to increase the temperature, so that all parts of the patient's body lying on the lying surface 11 can be heated; and the power of the heating layer 20 is adjustable. The heating power of the heating layer 20 is adjusted according to the adaptability of different patients and the surgical conditions. After the operation is completed, the power of the heating layer 20 can be increased to increase the temperature of the surface layer 10 to the temperature required for sterilization, thereby reducing the corrosion of the disinfectant water to the material of the surface layer 10 and improving the durability of the heating mattress 100.

[0037] In some embodiments, the heating layer 20 does not contact the inner wall of the cavity 12. The space between the heating layer 20 and the inner wall of the cavity 12 is filled with fillers such as cotton and sponge. This can not only make the heating mattress 100 more flexible, but also prevent the heat generated by the heating layer 20 from being directly transferred to the surface layer 10, causing the temperature of the surface layer 10 to be too high.

[0038] In other embodiments, the material of the surface layer 10 is made of highly soft, highly waterproof and high-temperature resistant leather, so as to prevent liquid from entering the cavity 12 inside the surface layer 10 from the outside of the surface layer 10 and affecting the heating of the heating layer 20. It can also prevent the surface layer 10 from being unable to withstand the high temperature and deforming or even melting when the heating layer 20 is sterilized at high temperature.

[0039] Further, see Figures 1 to 4 In one embodiment, the heating layer 20 is provided with a positive electrode plate 21 and a negative electrode plate 22. The positive electrode plate 21 is located on one side of the heating layer 20, and the negative electrode plate 22 is located on the other side of the heating layer 20 and is arranged opposite to the positive electrode plate 21. The heating layer 20 is sandwiched between the positive electrode plate 21 and the negative electrode plate 22, and the power cord 50 is electrically connected to the positive electrode plate 21 and the negative electrode plate 22 respectively.

[0040] In this way, by specially arranging the positive plate 21 and the negative plate 22 of the heating layer 20, the electrical connection between the heating layer 20 and the power line 50 is made safer and more stable. At the same time, the positive plate 21 and the negative plate 22 are arranged relatively to each other, and the heating layer 20 is sandwiched in the middle, so that the current can pass completely through the entire heating layer 20, and then the heating layer 20 can work and generate heat to the greatest extent possible.

[0041] In some embodiments, the material of the heating layer 20 can be high resistivity materials such as alloy wire, carbon fiber, graphene, etc., so as to further improve the maximum heating efficiency of the heating layer 20, and adjust the heating power of the heating layer 20 by adjusting the power of the power supply.

[0042] Further, see Figures 1 to 4 In one embodiment, the length of the positive electrode plate 21 is the same as the length of the side of the heating layer 20 ; and / or the length of the negative electrode plate 22 is the same as the length of the side of the heating layer 20 .

[0043] It can be understood that the heating layer 20 can be a rectangular shape, the side of the heating layer 20 is the long side of the rectangle, the length of the positive plate 21 is the same as the side length of the heating layer 20, and the length of the negative plate 22 is the same as the side length of the heating layer 20. In this way, the resistance of the heating layer 20 is increased by utilizing the characteristic that the larger the radius or width of the conductor, the greater the resistance, thereby improving the heating efficiency of the heating layer 20.

[0044] In some embodiments, the length of the positive plate 21 can be slightly shorter than the length of the side of the heating layer 20, and or the length of the negative plate 22 can be slightly shorter than the length of the side of the heating layer 20. This avoids the positive plate 21 and the negative plate 22 protruding due to installation errors, which may lead to short circuit leakage, thereby improving the safety of the heating mattress 100.

[0045] Further, see Figures 1 to 3In one embodiment, a buffer layer 30 is disposed in the cavity 12 , and the buffer layer 30 is disposed on a side of the heating layer 20 away from the lying surface 11 .

[0046] In this way, a buffer layer 30 is arranged in the cavity 12 and is arranged on the side of the heating layer 20 away from the lying surface 11 , so that the buffer layer 30 is filled between the heating layer 20 and the inner wall of the cavity 12 to improve the softness of the heating mattress 100 .

[0047] In some embodiments, the material of the buffer layer 30 can be high-density memory foam, so that even after the heating mattress 100 is buffered and deformed, the memory foam can still restore the heating mattress 100 to its original shape.

[0048] Further, see Figures 1 to 3 In one embodiment, the positive electrode plate 21 protrudes from the heating layer 20 and is embedded in the buffer layer 30 to facilitate the connection of the power line 50; and / or, the negative electrode plate 22 protrudes from the heating layer 20 and is embedded in the buffer layer 30 to facilitate the connection of the power line 50.

[0049] In this configuration, the positive electrode plate 21 protrudes and embeds into the buffer layer 30 , and or the negative electrode plate 22 protrudes and embeds into the buffer layer 30 , so that the power line 50 can be arranged in the soft buffer layer 30 , which facilitates the circuit arrangement between the power line 50 and the positive electrode plate 21 and the negative electrode plate 22 .

[0050] In some embodiments, small holes are provided on the positive plate 21 and the negative plate 22 for the power cord 50 to pass through, and the power cord 50 can be arranged through the small holes, further reducing the space occupied by the power cord 50.

[0051] Further, see Figures 1 to 4 In one embodiment, a thermal insulation layer 40 is provided in the cavity 12 , and the thermal insulation layer 40 is provided on a side of the heating layer 20 away from the buffer layer 30 , and the thermal insulation layer 40 is located between the lying surface 11 and the heating layer 20 .

[0052] In this way, a thermal insulation layer 40 is arranged in the cavity 12 between the heating layer 20 and the lying surface 11, so that the heat generated by the heating layer 20 reaches the lying surface 11 only after passing through the thermal insulation layer 40. In this way, the temperature change of the lying surface 11 is relatively slow and stable, which prevents the heating layer 20 from heating up too quickly. At the same time, the thermal insulation layer 40 can also block the current from passing through the lying surface 11, play an insulating role, and improve the safety of the heating mattress 100.

[0053] In some embodiments, one side of the thermal insulation layer 40 abuts against the inner wall of the cavity 12 and the other side abuts against the heating layer 20, so that the cavity 12 is actually filled, making the elasticity and memory of the heating mattress 100 better. At the same time, the thermal insulation layer 40 can better absorb the heat of the heating layer 20 and evenly transfer it to the lying surface 11.

[0054] Further, see Figures 1 to 2 In one embodiment, the heating mattress 100 further includes a temperature sensor 23 . The temperature sensor 23 passes through the buffer layer 30 and is fixed to the heating layer 20 to detect the temperature of the heating layer 20 .

[0055] In this configuration, a temperature sensor 23 is installed in the heating mattress 100 and fixed to the heating layer 20, so that the temperature of the heating layer 20 can be monitored in real time, thereby providing data reference for adjusting the heat of the heating layer 20 and improving the temperature control accuracy of the heating mattress 100.

[0056] In some embodiments, the temperature sensor 23 may be an NTC sensor, which has the characteristics of small size, light weight, wide temperature detection range, high accuracy, etc., and is suitable for the heating mattress 100, which needs to maintain a relatively stable temperature and have the characteristics of high temperature disinfection.

[0057] Further, see Figures 1 to 2 In one embodiment, a plurality of temperature sensors 23 are provided, and the plurality of temperature sensors 23 are arranged at intervals on the heating layer 20 to detect the accurate temperature of each position of the heating layer 20 .

[0058] In this way, the plurality of temperature sensors 23 are arranged at intervals at different positions of the heating layer 20 , so that the temperatures at different positions of the heating layer 20 can be detected, thereby ensuring that the heating of the heating layer 20 is uniform.

[0059] In this embodiment, four temperature sensors 23 are provided, and the four temperature sensors 23 are arranged in a rectangular shape and are respectively located at the four corners of the rectangle, so that the temperature of the four relatively areas of the heating layer 20 can be detected. The number of temperature sensors 23 needs to be based on the actual temperature detection requirements of the heating mattress 100 and the installation requirements of the temperature sensors 23. The number of temperature sensors 23 is not specifically limited here.

[0060] Further, see Figures 1 to 2 In one embodiment, a Velcro 60 is provided on a side of the surface layer 10 away from the lying surface 11 , and the Velcro 60 is used to fix the heating mattress 100 .

[0061] In this configuration, the Velcro 60 is installed on the back of the surface layer 10 , so that the heating mattress 100 can be attached to the operating bed through the Velcro 60 to prevent the heating mattress 100 from moving.

[0062] In some embodiments, two or more Velcro strips may be provided on the back of the heating mattress 100 to increase the adhesion of the Velcro strips 60 , thereby making the heating mattress 100 more stable and less likely to move on the operating bed.

[0063] The utility model also proposes an operating bed, which includes a heating mattress 100. The specific structure of the heating mattress 100 refers to the above embodiment. Since the operating bed adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0064] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
