Description

Technical Field

[0001] This invention belongs to the field of medical devices, and specifically relates to a fully digital electromagnetic tumor treatment device. Background Technology

[0002] Electric and magnetic field therapy is one of the latest cancer treatment methods. Its minimally invasive or non-invasive nature has attracted considerable attention from researchers. Studies have shown that electric fields can induce dielectrophoresis in some proteins of cancer cells during mitosis, thus affecting the cell's mitotic process. Furthermore, electric fields can interfere with DNA replication and repair in cancer cells. Meanwhile, magnetic fields can kill cancer cells by increasing reactive oxygen species in mitochondria and cytoplasm. Therefore, the combined use of electric and magnetic fields can effectively control and kill cancer cells, thereby inhibiting or even eliminating tumors and significantly prolonging the survival time of cancer patients. There are also treatments using patch electrodes to generate electric fields, applied for more than 18 hours daily.

[0003] Current technologies mainly rely on single electric field therapy or single magnetic field therapy. The mechanism of electric field therapy is that an electric field of a certain intensity can cause some proteins in cancer cells to undergo dielectrophoresis during mitosis, thereby affecting the mitosis of cancer cells and interfering with the DNA replication and repair of cancer cells. The mechanism of magnetic field therapy is that a magnetic field of a certain intensity can kill cancer cells by increasing reactive oxygen species in mitochondria and cytoplasm.

[0044] The power module 121 is connected to the power bank 11 and is used to provide external power to the whole system. The power module 121 adjusts the power of the power bank 11 and provides power at different frequencies and voltages according to the needs of the control unit by the digital control module 122.

[0045] The clock module 123 is connected to the digital control module 122 and provides time information to the digital control module 122 so that the digital control module 122 can control the power supply duration of the power module;

[0046] The digital control module 122 is responsible for controlling the electric and magnetic field strengths and frequencies of the entire system, and receives and processes information from the feedback unit, thereby adaptively adjusting the electromagnetic field of the system. If the strengths of the various signals fed back by the feedback unit are within the set operating range, there is no need to adjust the current operating parameters; if the strengths of the various signals fed back by the feedback unit are not within the set operating range, the strength and frequency of the electric and magnetic fields are adjusted by means of suppression or enhancement, so that the output of the electric and magnetic fields of the system always remains at the set operating strength.

[0047] The motor drive module 124 is connected to the magnetic field unit 13, receives parameters from the digital control module 122, and controls the rotation speed of the magnetic field unit 13.

[0048] The magnetic field control module 125 is connected to the magnetic field unit 13, receives parameters from the digital control module 122, and controls the magnetic field strength released by the magnetic field unit 13.

[0049] The boost module 126 processes the input voltage from the digital control module 122 and boosts it to meet the output voltage requirements of the system.

[0050] The switching network module 127 receives the output voltage from the boost module 126 and controls the order in which it flows to the different current sources 141 in the output unit 14.

[0052] There are at least four current sources 141, which are responsible for stabilizing the current flowing to the electric field unit 15 and are connected to the switch network module 127.

[0053] The sensor module 151 is connected to the current source 141, and collects the temperature information of the electric field unit and the magnitude of the magnetic field at the location of the electric field unit in real time, and converts them into signals to feed back to the signal amplifier 161.

[0057] The signal acquisition module 162 receives the signal from the signal amplifier 161 and transmits it to the digital control module 122.

[0058] The present invention was evaluated experimentally as follows:

[0059] Experimental Objective

[0060] To evaluate the safety of the fully digital electromagnetic tumor therapy device for organisms during in vitro treatment and its inhibitory effect on the growth of tumor cells in vivo.

[0061] Experimental equipment

[0062] Equipment: Fully digital electromagnetic tumor therapy instrument

[0063] Parameters: Output current 0.7mA, AC frequency 200kHz, action time 20min, magnetic field strength 80mT, electromagnet rotation speed 8r / min.

[0064] Experimental tumor cell lines

[0065] Mouse sarcoma S180 cell line.

[0066] Laboratory animals and their housing conditions

[0067] ICR mice, clean grade, 4-6 weeks old, 20 mice in total, 10 females and 10 males.

[0068] Laboratory animals were housed in mouse cages. Each cage contained mice belonging to the same group, fed with specially formulated mouse feed, and provided with free access to water. The temperature in the animal laboratory was maintained at approximately 25°C, the relative humidity at 40-70%, and the animals were exposed to 12 hours of light daily.

[0069] Experimental methods and equipment handling

[0070] (1) Under aseptic conditions, approximately 6 ml of ascites fluid was collected from 6 tumor-bearing mice and diluted with sterile physiological saline at a ratio of 1:3 to a concentration of approximately 8 × 10⁻⁶ ml. 6 0.2 ml of the solution was administered subcutaneously to the right shoulder of mice. The cell count was 1.6 × 10⁻⁶ cells / ml. 6 Each mouse was inoculated with tumor cells. After a certain period of time, the tumor volume of the mice was approximately 500 ± 25% mm. 3 At that time, the animals were divided into a treatment group and a control group (the tumors were not treated with electromagnetic therapy) based on the principle that the ratio of animal body weight to tumor volume was roughly balanced.

[0071] (2) Electromagnetic combination therapy group: Female mice were used as the treatment subjects, with 5 mice in each of the control and experimental groups. Following the "Guidelines for Antitumor Pharmacodynamics," the mice in the treatment group underwent one treatment using an electromagnetic therapy device. The mice were placed on an operating frame, with the magnet unit of the therapy device positioned below them, and the electrodes of the electric field unit placed on both sides of the mouse's tumor. One mouse was treated at a time, with a treatment time of approximately 20 minutes. At the start of treatment and every other day after treatment (days 0, 2, 4, 6, 8, 10, and 11), the mice were weighed, and the long and short diameters (a and b) of the tumor were measured using calipers. The experiment ended after 11 days of treatment. The animals were euthanized by neck dislocation, the tumor was removed, weighed, and pathological observation (HE staining) of the tumor tissue and the skin tissue at the tumor location was performed. The efficacy was evaluated based on the tumor weight, measured volume, and histopathological observation results.

[0072] (2) Electric field therapy group: Male mice were used as the treatment subjects, with 3 mice in each of the control and experimental groups. Following the "Guidelines for Antitumor Pharmacodynamics," the mice in the treatment group were treated once using an electromagnetic therapy device (magnetic field unit off). The mice were placed on the operating frame, and electrodes were placed on both sides of the tumor. One mouse was treated each time, and the treatment time was 20 minutes. Before the start of treatment and every other day after treatment (days 0, 2, 4, 6, 8, 10, and 11), the mice were weighed, and the long and short diameters (a and b) of the tumor were measured using calipers. The experiment ended after 11 days of treatment. The animals were euthanized by neck dislocation, the tumor was removed, weighed, and pathological observation (HE staining) of the tumor tissue and the skin tissue at the tumor location was performed. The efficacy was evaluated based on the tumor weight, measured volume, and histopathological observation results.

[0073] Data processing

[0074] Data This indicates that the tumor volume is 1 / 2ab. 2 (a = tumor long diameter, b = tumor short diameter); Relative tumor volume (RTV) = Vt / Vo (Vo: tumor volume before treatment, Vt: tumor volume after treatment); Tumor volume inhibition rate = (Tumor volume of control group - Tumor volume of experimental group) / Tumor volume of control group × 100%; Tumor growth inhibition rate = (Tumor mass of control group - Tumor mass of experimental group) / Tumor mass of control group × 100%. Statistical analysis between groups was performed using the T-test in Excel.

[0075] Experimental results

[0076] Regardless of whether the magnetic field unit was activated, the fully digital electromagnetic tumor therapy device exhibited a certain inhibitory effect on tumor growth in mice. The tumor volume inhibition rates were 112.71% and 25.87% with the magnetic field unit activated and 25.19% and 24.35% with the magnetic field unit deactivated, respectively. Furthermore, when the magnetic field unit was activated, there was a significant difference in tumor volume between the experimental and control groups starting from day 10 post-treatment. Tumor sections showed that tumor cells in the experimental group exhibited more atrophy, deformation, and death compared to the control group. This demonstrates that the fully digital electromagnetic tumor therapy device does have a certain inhibitory effect on tumors, and the inhibitory effect is better when the magnetic field unit is activated. In addition, the results also showed no significant difference in body weight between the control and experimental groups regardless of whether the magnetic field unit was activated, demonstrating the good biocompatibility of the fully digital electromagnetic tumor therapy device. Specific experimental results are shown in Tables 1-6 and... Figures 3-11 .

This demonstrates that the fully digital electromagnetic tumor therapy device with the magnetic field unit activated does indeed have a good tumor treatment effect.

[0095] Figure 5 The graph shows the effect of the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off on the tumor volume inhibition in mice. According to the data in Table 4, the tumor volume inhibition rate is 25.87%, which proves that the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off still has a tumor treatment effect, but it is not as good as the treatment effect with the magnetic field unit turned on.

[0096] Figure 6The graph shows the inhibitory effect of the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off on the relative tumor volume in mice. The relative tumor volume in the control group increased from 1 to 2.86±0.93, while the relative tumor volume in the experimental group increased from 1 to 2.25±0.95. This demonstrates that the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off still has a tumor treatment effect, but it is not as effective as the treatment effect with the magnetic field unit turned on.

[0097] Figure 7 The graph shows the effect of the fully digital electromagnetic tumor therapy device with the magnetic field unit activated on the body weight of mice. According to the data in Table 5, the body weight growth rate of both the control group and the experimental group was 19.62%, which proves that the fully digital electromagnetic tumor therapy device with the magnetic field unit activated has good biocompatibility.

[0098] Figure 8 The graph shows the effect of the fully digital electromagnetic tumor therapy device with the magnetic field unit activated on the relative body weight of mice. The relative body weight of the control group increased from 1 to 1.20±0.07, while that of the experimental group increased from 1 to 1.20±0.03. There was no difference in the relative body weight increase between the control group and the experimental group, which proves that the fully digital electromagnetic tumor therapy device with the magnetic field unit activated has good biocompatibility.

[0099] Figure 9 The graph shows the effect of the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off on the body weight of mice. According to the data in Table 6, the body weight growth rate of the control group was 11.23%, and the body weight growth rate of the experimental group was 15.65%, which proves that the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off has good biocompatibility.

[0100] Figure 10 The graph shows the effect of the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off on the relative body weight of mice. The relative body weight of the control group increased from 1 to 1.09±0.02, while the relative body weight of the experimental group increased from 1 to 1.14±0.04. The relative body weight increase of the experimental group was greater than that of the control group, which proves that the fully digital electromagnetic tumor therapy device with the magnetic field unit turned off has good biocompatibility.

[0101] Figure 11 The image shows H&E staining of tumors when the magnetic field unit is activated. More cells in the experimental group died, and more cells underwent morphological changes, demonstrating that the fully digital electromagnetic tumor therapy device with the magnetic field unit activated does indeed have a tumor treatment effect.
