Description

Technical Field

[0001] This utility model relates to the field of tumor hypoxia research, and in particular to a radiofrequency excitation control device for tumor hypoxia research. Background Technology

[0002] Tumor hypoxia research explores the phenomenon of insufficient oxygen supply in the tumor microenvironment to reveal how hypoxia drives malignant tumor progression and develop targeted intervention strategies. Radiofrequency excitation control experiments are used to achieve dynamic simulation and regulation of the tumor microenvironment. Existing radiofrequency devices generate radiofrequency signals of specific frequencies and powers through radiofrequency signal excitation modules, which are then transmitted to radiofrequency coils after parameter adjustment by radiofrequency signal control modules. However, due to the fixed position of the coils, it is difficult to adapt to tumor models of different sizes. In addition, these devices adopt an open structure with insufficient electromagnetic shielding, which affects experimental safety and data reliability.

[0003] To address the aforementioned issues, a radiofrequency excitation control device for tumor hypoxia research has been developed. Utility Model Content

[0004] To overcome the shortcomings of existing devices, such as fixed coil positions that are difficult to adapt to tumor models of different sizes, and the open structure of these devices with insufficient electromagnetic shielding that affects experimental safety and data reliability, this invention provides a radio frequency excitation control device for tumor hypoxia research.

[0005] The technical solution of this utility model is as follows: a radio frequency excitation control device for tumor hypoxia research, comprising a mounting frame, a radio frequency signal excitation module mounted on the upper left side of the mounting frame, a radio frequency signal control module mounted on the upper right side of the mounting frame, the radio frequency signal control module and the radio frequency signal excitation module being electrically connected, an electric push rod mounted on the right side of the mounting frame, a lifting platform connected to the telescopic end of the electric push rod, a radio frequency coil connected to the lifting platform, and the radio frequency coil being electrically connected to the radio frequency signal control module.

[0006] More preferably, it also includes a fixing cylinder, with four fixing cylinders connected to the bottom of the mounting frame, and each fixing cylinder is slidably connected to the radio frequency coil.

[0007] More preferably, it also includes hinges, with two hinges connected to the front sides of both the left and right sides of the mounting frame, and a protective frame connecting adjacent hinges.

[0008] More preferably, it also includes magnetic suction components, with magnetic suction components connected to both the front and rear sides of the bottom of the mounting frame, and the magnetic suction components can be attracted to the adjacent protective frame.

[0009] More preferably, the lifting platform is provided with a baffle on the right side.

[0010] More preferably, the protective frame also includes a transparent material in the middle.

[0011] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages:

[0012] This invention uses an electric push rod to drive the vertical movement of the lifting platform, which in turn drives the radio frequency coil to be precisely adjusted to the target height, so that the radio frequency field uniformly covers the sample area, thereby adapting to the testing requirements of samples of different specifications. The protective frame encloses the electromagnetic environment, which helps to improve the safety of the test and prevents electromagnetic diffusion from affecting the test. At the same time, the operator can observe the test situation in real time through the transparent structure in the middle of the protective frame. Attached Figure Description

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0019] A radiofrequency excitation control device for tumor hypoxia research, such as Figures 1-4As shown, the installation includes a mounting frame 1. An RF signal excitation module 2 is mounted on the upper left side of the mounting frame 1, and an RF signal control module 3 is mounted on the upper right side of the mounting frame 1. The RF signal control module 3 and the RF signal excitation module 2 are electrically connected. An electric push rod 7 is mounted on the right side of the mounting frame 1. A lifting platform 5 is connected to the telescopic end of the electric push rod 7. A baffle is provided on the right side of the lifting platform 5. An RF coil 4 is connected to the lifting platform 5. The RF coil 4 and the RF signal control module 3 are also electrically connected. Four fixing cylinders 6 are connected to the bottom of the mounting frame 1. The fixing cylinders 6 are all slidably connected to the RF coil 4. Two hinges 9 are connected to the front of both the left and right sides of the mounting frame 1. A protective frame 8 is connected between adjacent hinges 9. The middle part of the protective frame 8 is made of transparent material. Magnetic components 10 are connected to the front and rear sides of the bottom of the mounting frame 1. The magnetic components 10 can attract adjacent protective frames 8.

[0020] It should be noted that tumor hypoxia research explores the phenomenon of insufficient oxygen supply in the tumor microenvironment to reveal how hypoxia drives malignant tumor progression and develop targeted intervention strategies. This is achieved through radiofrequency excitation control experiments to dynamically simulate and regulate the tumor microenvironment. In this experiment, one side of the protective frame 8 is first flipped outwards, and the sample to be tested is placed under the radiofrequency coil 4. If the initial space under the radiofrequency coil 4 is not suitable for the sample size, the electric push rod 7 is activated. The telescopic end of the electric push rod 7 drives the lifting platform 5 to move vertically along the fixed cylinder 6, precisely adjusting the radiofrequency coil 4 to the target height, ensuring the radiofrequency field uniformly covers the sample area. Then, the protective frame 8 is flipped inwards to reset, and the magnetic suction component 10 automatically attaches to the protective frame 8, sealing the electromagnetic environment and improving experimental safety while preventing electromagnetic diffusion from affecting the experiment. Subsequently, the radiofrequency signal excitation module 2 generates a radiofrequency signal of a specific frequency and power, which is transmitted to the radiofrequency coil 4 after parameter adjustment by the radiofrequency signal control module 3, forming a controllable electromagnetic field environment in the sample area. The transparent material in the middle of the protective frame 8 allows the operator to observe the experimental process in real time, enabling timely intervention and adjustments.

These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
