Description

Technical Field

[0001] The utility model relates to the technical field of treatment beds, and particularly relates to a device for heating a linear accelerator treatment bed. Background Art

[0002] Radiation therapy is one of the treatment methods. A linear accelerator is involved in the medical devices related to radiation therapy. When a patient undergoes treatment with a linear accelerator, the patient needs to take off his or her clothes to ensure the treatment effect. However, after taking off the clothes, the patient's body surface feels uncomfortable due to getting cold, especially for patients with weak bodies during illness. The bed board of the linear accelerator itself will also conduct heat to the patient's body surface, causing heat to conduct from the patient's body to the bed board. Since the patient's body will contract muscles and shiver, or even "shiver" after getting cold, it will cause the radiation treatment position to be inaccurate and even the radiation marking points to shift, which is not conducive to treatment. Therefore, it can be considered to solve this problem by heating. In addition, since the body parts of each patient that need to be radiated are different, when heating, it is required to be able to heat any part of the whole body. Content of the Utility Model

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0023] As Figures 1-4 shown, a device for heating a linear accelerator treatment bed includes a heater 10 for heating and a support device 20 for supporting the heater 10. The heater 10 is used for heating and heats the linear accelerator treatment bed through thermal radiation. During actual use, the heater 10 heats the air and can also raise the temperature of the human body surface to avoid spasms and tremors caused by the human body getting cold. The support device 20 is used to lift the heater 10 to a sufficient height so that the heater 10 can be placed in a suitable position.

[0024] The heater 10 includes an outer cover 11. An electric heating tube 12 for generating heat is arranged inside the outer cover 11. A reflective layer 111 for reflecting heat is arranged on the inner wall of the outer cover 11. A power fan 13 for blowing hot air is arranged on one side of the electric heating tube 12. The electric heating tube 12 generates heat through electricity and radiates the heat outwards. The outer cover 11 is used to protect the electric heating tube 12. As Figure 3 and 4 shown, a reflective layer 111 is arranged on the inner wall of the outer cover 11 to reflect the thermal radiation. In specific implementation, the reflective layer 111 is made of a material coating or directly made of a whole piece of material. Specific materials are, for example, tin foil. At the same time, the surface of the reflective layer 111 is processed into a mirror surface to improve the reflection effect. The power fan 13 is used to generate wind and blow the air heated by the electric heating tube 12 to the outside, thereby realizing temperature increase and heating of the bed board or the patient's body surface.

[0025] In some preferred implementation manners, as Figure 4As shown, the heater 10 further includes a main body housing 14. The outer cover 11 is disposed at one end of the main body housing 14. The electric heating tube 12 is supported by a bracket and disposed inside the outer cover 11, and the bracket is fixedly connected to the outer cover 11. The power fan 13 includes a fan blade 131 and a motor 132. The motor 132 is disposed inside the main body housing 14. The output end of the motor 132 is connected with the fan blade 131, and the fan blade 131 is located on the side of the electric heating tube 12 close to the main body housing 14. In a specific implementation, a circuit for heating the electric heating tube 12 and a circuit for driving the power fan 13 are further disposed inside the main body housing 14, and the circuit includes a power supply and wires, etc. The power supply is disposed inside the main body housing 14, and the wires are connected to the power fan 13 and the electric heating tube 12. The circuit further includes a control circuit board for managing the power supply, and an operation panel for personnel operation is connected to the control circuit board. The operation panel is fixedly disposed outside the main body housing 14 for easy operation by personnel.

[0026] In some preferred embodiments, the electric heating tube 12 includes a first tube body 121 and a second tube body 122 arranged concentrically. The outer diameter of the first tube body 121 is larger than that of the second tube body 122. The electric heating tube 12 is provided with two tube bodies, namely the first tube body 121 and the second tube body 122, which can improve the heating effect and can be separately controlled by independently connecting circuits, thereby making the control of the heating operation more refined.

[0027] The support device 20 includes a root rod 21 and a connecting rod assembly 22. The root rod 21 is used to support the connecting rod assembly 22 to lift the connecting rod assembly 22 to a certain height. In a specific implementation, the root rod 21 is columnar.

[0028] The connecting rod assembly 22 includes a first connecting member 221. The first connecting member 221 is rotatably connected to the upper end of the root rod 21. A first rod 222 and a second rod 223 are rotatably connected to the first connecting member 221. The first rod 222 and the second rod 223 are rotatably connected to a second connecting member 224. The first connecting member 221, the first rod 222, the second rod 223 and the second connecting member 224 form a four-bar linkage. A third rod 225 and a fourth rod 226 are rotatably connected to the second connecting member 224. The third rod 225 and the fourth rod 226 are rotatably connected to a third connecting member 227. The second connecting member 224, the third rod 225, the fourth rod 226 and the third connecting member 227 form a four-bar linkage. The whole heater 10 is rotatably disposed on the third connecting member 227. As Figure 2As shown, in the specific implementation process, the first connecting member 221, the first rod 222, the second rod 223, and the second connecting member 224 form a four-bar linkage. In addition, the second connecting member 224, the third rod 225, the fourth rod 226, and the third connecting member 227 form a four-bar linkage. Based on the mechanical characteristics of the four-bar linkage, in actual use, the position of the corresponding part can be adjusted through the rotation and cooperation of the structure. In this solution, since the heater 10 is integrally rotatably arranged on the third connecting member 227, the heater 10 can move along with the activities of the above two four-bar linkages. Thus, in the heating device of this solution, during specific use, the heating position of the heater 10 can be adjusted arbitrarily to meet the temperature rise of different parts on the patient, making it a highly flexible existence.

[0029] When this solution is specifically used, the heating device is powered on, and the electric heating tube 12 starts to generate heat, and then has the ability to radiate heat outward. At the same time, the power fan 13 starts to blow air, blowing out the heated air and starting to heat up the external environment. The whole heating device is moved to the side of the treatment bed. Because of the linkage assembly 22 composed of the four-bar linkage structure, and the first connecting member 221 is circumferentially rotatably connected to the root rod 21, through the external force pull of the medical staff, the heater 10 can be pulled to any required position, which is flexible, convenient and easy to use.
