Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more particularly to a far-infrared irradiation device for treating tumors. Background Art

[0002] At present, cancer has become one of the major diseases that seriously threaten human life and health. According to the latest report from the World Health Organization, there will be approximately 19.3 million new cases of cancer and nearly 10 million deaths worldwide in 2020. Although medical technology has improved rapidly and cancer treatments have made great progress, cancer is difficult to treat due to its complex pathogenesis and high degree of personalization. Surgical resection, radiotherapy, and chemotherapy are the main treatments for malignant tumors. However, these methods have limitations in clinical practice. For example, the side effects of radiotherapy or chemotherapy may damage adjacent or distant healthy tissues or organs, while surgical resection of tumors and postoperative wound healing may induce distant metastasis.

[0003] Non-invasive cancer treatment is becoming a promising strategy. Far infrared irradiation is a convenient, non-contact and non-invasive method for treating diseases. For example, far infrared irradiation can improve myocardial ischemia, diabetes, chronic kidney disease and improve blood circulation in skin tissue. Far infrared has positive biological effects. Far infrared therapy belongs to physical therapy and is widely used in clinical practice. Far infrared has strong penetration and radiation power, significant temperature control effect and resonance effect, and is easily absorbed by objects and converted into internal energy of objects. After being absorbed by the human body, far infrared can resonate water molecules in the body, activate water molecules, and enhance their intermolecular binding force, thereby activating biological macromolecules such as proteins and placing biological cells at the highest vibration energy level. Compared with high-energy radiotherapy, infrared-based therapy shows low toxicity and good safety, so it can be used as an auxiliary treatment tool for combined tumor treatment.

[0004] Graphene is an allotrope of carbon, with carbon atoms arranged in sp 2 Hybrid bonding forms a single layer of hexagonal honeycomb lattice graphene, sp 2 Hybridization is formed by one s orbital and two of the three p orbitals in the same layer.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] The embodiment of the present invention discloses a far-infrared irradiation device for treating tumors, comprising:

[0045] Induction box 1,

[0046] The far-infrared emitting film 2 is arranged on the side wall of the induction box 1; the far-infrared emitting film 2 comprises: a graphene layer 21, a polyester substrate layer 22 and a forked electrode 23; the graphene layer 21 is arranged between two layers of the polyester substrate layer 22; the forked electrode 23 is connected to the graphene layer 21;

[0047] The control panel 3 is arranged on the outer wall of the induction box 1; a power supply 31, a microcontroller and a control circuit are arranged in the control panel 3; the graphene layer 21 is connected to the control circuit through a wire; the interdigitated electrodes 23 are connected to the power supply 31; the power supply 31 is connected to the control circuit, and the microcontroller is connected to the control circuit.

[0048] In order to further optimize the above technical solution, the control circuit of the far-infrared irradiation device has two control modes: manual and Bluetooth, and has timing and temperature adjustment functions; the far-infrared emitting film of the far-infrared irradiation device can be customized into any shape to meet the needs of different occasions, and the wires connected to the control circuit can be extended, greatly enriching its application scenarios.

[0049] In order to further optimize the above technical solution, the power source 31 is a lithium-ion battery, and the power source 31 provides power for the far-infrared emission film 2 and the control panel 3 .

[0050] In order to further optimize the above technical solution, the side panels of the induction box 1 are acrylic panels 11, and the bottom panel is epoxy resin panel 12, and the side panels and the bottom panel are bonded to each other. The side panels and the bottom panel are bonded by hydrogel, which facilitates the disassembly and assembly of the induction box 1.

[0051] In order to further optimize the above technical solution, the graphene layer 21 of the far-infrared emitting film 2 is provided with a first electrode 24 and a second electrode 25, and the first electrode 24 and the second electrode 25 are connected to the control circuit through a wire. The first electrode 24 and the second electrode 25 have no positive and negative distinction, and can be connected arbitrarily after the far-infrared emitting film 2 is disassembled.

[0052] In order to further optimize the above technical solution, a temperature sensor 4 is provided inside the induction box 1. The temperature sensor 4 is provided on the surface of the polyester substrate layer 22, and the temperature sensor 4 is connected to the microcontroller. The temperature sensor 4 detects the temperature of the far-infrared emission film, and transmits the detection result to the microcontroller, and after the microcontroller processes the information, the temperature is transmitted to the display screen 32. After the microcontroller sets the target temperature, the temperature of the far-infrared emission film 2 can be quickly and accurately stabilized at the set temperature through the PID temperature control circuit.

[0053] In order to further optimize the above technical solution, a display screen 32 is provided on the control panel, and the display screen 32 is connected to the microcontroller. The display screen 32 is an OLED screen.

[0054] In order to further optimize the above technical solution, the microcontroller is used to store, process and transmit data. The microcontroller sets the corresponding working state, including working time, working power and working mode, according to the input data of the input unit.

[0055] In order to further optimize the above technical solution, a button 33 is provided on the control panel 3, and the button 33 is connected to the control circuit. The button 33 can set the working time of the far-infrared emission film 2 through the timing circuit in the control circuit, and the display screen 32 displays the working time of the device.

[0056] In order to further optimize the above technical solution, the control circuit includes: PID temperature control circuit, timing circuit, MOS tube switch drive circuit and Bluetooth control circuit. The Bluetooth control circuit can realize the Bluetooth connection between the device and the mobile phone, and the GPIO port of the microcontroller can be controlled to output a voltage signal through the mobile phone APP.

[0058] In order to further optimize the above technical solution, a ventilation hole 13 is opened on the side wall of the induction box 1.

[0059] like Figure 5 As shown, each module in the circuit is controlled by the microcontroller U5. After the written program is burned into the microcontroller, the working mode of the circuit is set through switches SW1-SW5. P2 is the Bluetooth module interface. After connecting to the Bluetooth control circuit, the working time and power of the far-infrared emission film 2 can be controlled on the mobile phone. The photocoupler U6 completely isolates the upper and lower circuits to reduce circuit interference. The temperature measured by the temperature sensor U7 is displayed on the OLED screen U1 to achieve precise temperature control.

[0060] like Figure 7 As shown in the figure, appropriate PID parameters are obtained through simulation, and the obtained PID parameters are input into the microcontroller. After setting the temperature of the far-infrared emission film, the microcontroller will adjust the output of the PWM wave of the GPIO port in real time according to the temperature measured by the temperature sensor, thus realizing closed-loop control. Therefore, as long as the controlled quantity deviates from the specified value, a corresponding control action will be generated to eliminate the deviation, thereby realizing precise temperature control.

[0061] It needs to be explained that the term "PWM" (PWM: Pulse Width Modulation) is pulse width modulation, abbreviated as PWM, which is a very effective technology that uses the digital output of a microprocessor to control analog circuits. It is widely used in many fields from measurement, communication to power control and conversion.

The working state of the far-infrared emitting film 2 is controlled by the control circuit. When a tumor-bearing mouse is placed in the far-infrared emitting device, the far-infrared rays generated by the far-infrared emitting film 2 can irradiate the tumor-bearing side of the mouse. After a period of irradiation, Figure 3 The experimental results shown in the figure indicate that far-infrared irradiation has an inhibitory effect on tumor growth in tumor-bearing mice.

[0064] The other technical solutions of this embodiment are the same as those in Embodiment 1 and will not be described in detail here.

A culture dish 5 is placed on the far-infrared emitting film 2, and cultured tumor cells are contained in the culture dish 5. The far-infrared emitting film 2 is controlled by the control circuit to work, and far-infrared rays are generated to irradiate the tumor cells. And the experimental results show that under the irradiation of far-infrared rays, tumor cells have a killing effect, and the killing effect is obvious.
