[0017] like Figure 1-3 As shown, a heating device for radiotherapy in the present application includes a clamping component 1, a supporting component 2, a heating component 3 and a control component 4. The clamping component is used to clamp and fix on the edge of a bed. The heating component is connected to the clamping component through the supporting component. The control component can be used to control the temperature of the heating component to prevent insufficient temperature or overheating. The supporting component is foldable, so that the volume of the device can be reduced when not in use, thereby reducing space occupancy and facilitating the storage and placement of the device.

[0018] refer to Figure 1 and Figure 3 The clamping assembly 1 includes a U-shaped seat 12, a pressure block 13, a screw 14 and a handle 15. The pressure block 13 is arranged inside the U-shaped seat 12, and the handle 15 is arranged outside the U-shaped seat 12. The screw 14 is threadedly connected to the U-shaped seat 12, and its two ends are fixedly connected to the pressure block 13 and the handle 15 respectively.

[0019] Furthermore, a non-slip pad is provided in the groove of the U-shaped seat, which is inserted into the edge of the bed through the groove, and the handle is rotated to drive the pressure block to press the edge of the bed, which can increase the firmness of the device when fixed to avoid falling during use, and the device can be fixed at different positions on the edge of the bed according to the different heating and warming positions of the patient.

[0020] refer to Figure 1 and Figure 2 Furthermore, a connecting column 11 is provided at the upper end of the clamping assembly 1, and a slider 112 is provided at the lower end of the connecting column 11, a slide groove 121 is provided at the upper end of the U-shaped seat 12, and the slider 112 is slidably arranged in the slide groove 121, wherein the slider and the slide groove are interference fit, so that after the clamping assembly is fixed on the bed, the heating assembly can still be moved in a small range to adjust the position, thereby increasing the practicality of the device.

[0021] refer to Figure 1 , wherein the support assembly 2 includes a support frame 21 and a connecting frame 22, one end of the support frame 21 and the connecting frame 22 are both provided with a connecting seat 211, the other end of the connecting frame 22 can be rotatably inserted into the connecting seat 211 at one end of the support frame 21, and one end of the heating assembly 3 can be rotatably inserted into the connecting seat 211 at one end of the connecting frame 22, and both are fixed by bolts 212 and nuts 213.

[0022] In addition, a connecting column 11 is provided at the upper end of the clamping assembly 1, and the upper end of the connecting column 11 is hinged to the other end of the support frame 21. A threaded sleeve 23 is provided on the support frame 21, and the threaded sleeve 23 can be threadedly connected to the support frame 21 only, or can be threadedly connected to the support frame 21 and the connecting column 11 at the same time after moving downward.

[0023] refer to Figure 2 Specifically, a connecting groove 111 is provided at the upper end of the connecting column 11, and a connecting block 214 is provided at the other end of the supporting frame 21. The connecting block 214 can be rotatably inserted into the connecting groove 111, so that the supporting frame 21 can be rotated and folded on the clamping assembly 1.

[0024] The other end of the connecting frame can be rotatably inserted into the connecting seat at one end of the supporting frame, and the other end of the supporting frame is hinged to the connecting column. Therefore, when not in use, the threaded sleeve can be adjusted to move upwards and only be threadedly connected to the supporting frame 21, so that both the supporting frame and the connecting frame can be rotated and folded on the clamping assembly, reducing the space occupied by the device and facilitating storage and placement; or when in use, after rotating so that the connecting column and the supporting frame are coaxial, the threaded sleeve is adjusted to move downwards and is threadedly connected to the supporting frame 21 and the connecting column 11 at the same time, so that the connecting column and the supporting frame are relatively fixed.

[0025] refer to Figure 1 Furthermore, multiple groups of connecting frames 22 may be provided. When multiple groups of connecting frames are provided, in two adjacent groups of connecting frames 22, the other end of one group of connecting frames 22 is rotatably inserted into the connecting seat 211 of the other group of connecting frames 22 and fixed by bolts 212 and nuts 213.

[0026] In this embodiment, two groups of connecting frames are provided. In other embodiments, one or more groups of connecting frames can be provided to increase the position adjustment range of the device, and the other end of one group of connecting frames 22 of two adjacent groups of connecting frames in the multiple groups of connecting frames can be rotatably inserted into the connecting seat 211 of another group of connecting frames 22, so that the multiple groups of connecting frames can still be rotated and folded and stored in the clamping assembly, thereby reducing the space occupied by the device when the device is not in use, and facilitating storage and placement.

[0027] refer to Figure 1Furthermore, the support frame 21 and the connecting frame 22 are both telescopic rods, and the support frame and the connecting frame are both telescopic rods, so that the length of the support frame and the connecting frame can be adjusted, further increasing the adjustment range of the height and width of the heating component in the device, thereby increasing the applicability of the device. Optionally, the telescopic rods are composed of a fixed rod and a movable rod. Among them, one end of the movable rod can be rotatably and slidably inserted into the fixed rod, and is fixed by a stop bolt, so that the direction of the support frame 21 and the connecting frame 22 can be adjusted arbitrarily.

[0028] The heating component 3 can be heated by electric heating wire, PTC ceramic or infrared. Furthermore, in order to increase the uniformity of heating and keeping warm, when the electric heating wire is used for heating, a fan can be set on the heating component to quickly blow hot air toward the radiotherapy body plate or the local warming area of ​​the radiotherapy patient, thereby accelerating the heating of the radiotherapy body plate and ensuring the uniformity of heating of the local warming area of ​​the patient. The electric heating wire can also be hidden and protected, and the hot air can be blown out by the fan to prevent the bright light generated by the electric heating wire from causing glare, or the electric heating wire from causing burns.

[0029] refer to Figure 1 and Figure 3 , wherein the control component 4 includes a controller 41 and a temperature sensor 42, and the temperature sensor 42 is electrically connected to the controller 41 through a wire 43. The temperature sensor is connected to the controller through a wire, and the temperature sensor can be placed in the local warming area of ​​the patient, and the heating temperature of the heating component is sensed by the temperature sensor, and the output power of the heating component is controlled after being transmitted to the controller through the wire to prevent the problem of insufficient heating temperature or overheating.

[0030] When in use, when the patient is not receiving treatment, the device can be fixed on the edge of the bed to heat the radiotherapy body plate with a lower temperature, reducing the patient's discomfort due to cold when lying flat on the radiotherapy body plate; during the treatment process, the device can be moved to heat the exposed part of the patient to prevent the patient from feeling uncomfortable due to cold due to low room temperature. After use, the device can be folded to reduce the volume, thereby reducing the space occupied by the device, making it easier to store and place the device.

[0031] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present utility model should be within the protection scope of the present utility model.
