Description

[0002] Tumor hyperthermia refers to a type of treatment method that uses heating to treat tumors. Tumor hyperthermia has become the fifth largest treatment after surgery, radiotherapy, chemotherapy and immunotherapy. It is a new and effective means of treating tumors and is called "tumor green therapy". Among them, bladder tumors provide an anatomical basis for the implementation of tumor hyperthermia because they have heated cavities. There are currently two ways to heat bladder tumors: 1. Connect the bladder in the body with a three-lumen catheter and heat it with hot saline in the body; 2. Insert a metal heating guide wire into the bladder and heat the metal heating guide wire after connecting the wire through the urethra. Both require repeated invasive urethral operations during regular bladder tumor hyperthermia. This repetitive catheterization operation is very likely to lead to postoperative complications, such as infection, bleeding, urethral stenosis, etc., and cause great physical and psychological trauma to patients. Summary of the invention

[0003] Based on this, it is necessary to provide a thermal therapy floatation device, heating equipment, thermal therapy system, placement rod and thermal therapy assembly to address the problem that the existing tumor thermal therapy methods require the device to be repeatedly inserted into the human body during each thermal therapy, causing great pain to the patients.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0033] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figure 1 , this embodiment provides a wireless tumor thermal therapy floatation device, which includes a shell 1, a metal coil 2, a temperature sensor, a wireless transmission module and a power module. The overall shape of the shell 1 can be set to a cylinder, which is sealed as a whole and has a blunt angle smooth treatment at the edge to prevent damage to the tissue when it is placed in the human body. The material of the shell 1 is generally non-metallic material, and a polymer material can be selected, and an antibacterial, hydrophilic, and anti-adhesion coating can be coated on the surface of the shell 1 to reduce the stimulation to the human body when the shell 1 is placed. The internal space of the shell 1 is divided into a cavity for installing parts and an air cavity for suspending the entire thermal therapy floatation device in the liquid. The air cavity can be filled with air or an inert gas in order to provide buoyancy for the entire floatation device. The design size of the air cavity size (i.e., the size of the buoyancy) requires that the entire floatation device is suspended in a liquid, such as urine in the bladder, to prevent the floatation device from falling on a certain part of the inner wall of the bladder to cause stimulation, and the heating temperature at the tumor cannot meet the requirements.

[0037] The metal coil 2 can be made of copper wire, which is wound into a coil structure and forms a complete loop. The metal coil 2 is arranged in the cavity of the shell 1. The metal coil 2 is used to generate heat by inducing the alternating magnetic field transmitted from the outside. The generated heat is dissipated to the outside through the shell 1, thereby performing thermal therapy on the inserted part. Furthermore, the cavity is filled with a heat-conducting liquid, such as transformer oil, which can evenly transfer the heat generated by the metal coil 2 to the surface of the shell 1 while playing an insulating role. The temperature sensor, the wireless transmission module and the power module are also arranged in the cavity, and the three are integrated together to form an integrated unit 3. The temperature sensor is used to detect the temperature in the cavity and generate a corresponding temperature signal. The temperature signal is wirelessly transmitted to an external receiving device through the wireless transmission module. Since the energy for the metal coil 2 to generate heat is powered by the external alternating magnetic field. The power module can use a lithium battery, and the volume can be made very small, and it only needs to power the temperature sensor and the wireless transmission module.

[0038] Please refer to Figure 2 In another embodiment, compared with the above embodiment, only a cavity is provided in the housing 1, and no air cavity is provided separately. In this case, the cavity is not filled with a heat transfer liquid. The volume of the enclosed cavity is appropriately enlarged, and while the integrated unit 3 is installed inside, the cavity also acts as an air cavity, so that the thermal therapy floatation device can float in the liquid. In addition, in another design, the volume of the cavity is not enlarged, which will cause the thermal therapy floatation device to lose its floating function, but can further reduce the volume of the entire thermal therapy floatation device, making it more suitable for use in parts of the human intestines, female reproductive tracts, and other parts where there is no floating scene.

[0039] In one embodiment, the wireless tumor thermal therapy floater also includes a shooting module. The shooting module includes a camera module and a light source. The camera module and the light source are both mounted on the housing 1. The installation direction of the camera module and the light source on the housing 1 is not limited, and the number of installations is also not limited. Camera modules of different numbers and positions are designed according to the needs of shooting and microscopy to ensure that the observation range meets the required standards as much as possible. The camera module is used to shoot images outside the housing 1, and a miniature electronic camera, such as a CCD camera, can be used. The CCD camera can convert the video into a digital signal and transmit the digital signal to an external receiving instrument through a wireless transmission module. The receiving instrument has a display screen, which converts the received digital signal into a video, and finally displays all the temperature and video information detected by the thermal therapy floater through the display screen. The light source is used to illuminate the shooting direction of the camera module.

[0040] In another embodiment, the housing 1 is further provided with a docking slot at one end in the length direction thereof, in which a magnet 4 is fixedly connected, so that the wireless tumor thermal therapy floating device can be moved and placed by cooperating with the magnet 4 and the corresponding magnetic adsorption device.

[0041] In another embodiment, a pulse heating device is proposed, which is used in conjunction with the wireless tumor hyperthermia floatation device mentioned in the above embodiment. Specifically, the pulse heating device includes a fixing member 5 that can be fixed on the human body, a magnetic field generating module and a control module. The fixing member 5 can be set as a waist belt structure, and the magnetic field generating module is fixedly connected to the front and back sides of the waist belt to increase the magnetic field strength generated by the magnetic field generating module. The magnetic field generating module is used to transmit an alternating magnetic field to the wireless tumor hyperthermia floatation device in the above embodiment, so that the metal coil 2 generates heat by induction. The magnetic field generating module includes a transmitting coil and a power supply unit. The power supply unit can use a mobile power supply, which can be plugged and unplugged with the power supply port of the transmitting coil, so as to facilitate power supply anytime and anywhere and patient disassembly and movement. The control module is also fixedly connected to the fixing member 5. The control module is used to receive the temperature signal sent by the wireless transmission module in the wireless tumor hyperthermia floatation device, and the control module has a set of control logic built in. The control logic includes comparing the value of the received temperature signal with the temperature threshold interval set by the control module for judgment. If the value is less than the minimum value of the temperature threshold interval, the alternating magnetic field strength of the magnetic field generating module is increased, that is, the heating temperature of the metal coil 2 is increased. If the value is greater than the maximum value of the temperature threshold interval, the alternating magnetic field strength of the magnetic field generating module is reduced, that is, the heating temperature of the metal coil 2 is reduced. If the value is within the temperature threshold interval, the alternating magnetic field strength of the magnetic field generating module is maintained, that is, the heating temperature of the metal coil 2 is maintained. The temperature threshold interval can be set by the adjustment switch on the belt. In addition, a mobile phone can be used to connect the control module signal on the belt through Bluetooth or other methods, and then the temperature threshold interval can be set using the mobile phone.

[0042] Please refer to Figure 3In another embodiment, a tumor pulse hyperthermia system is proposed, which includes the wireless tumor hyperthermia floater and pulse heating device mentioned in the above embodiment. The two are used in combination. The hyperthermia floater is placed inside the human body, and the fixing part 5 is worn at the corresponding position of the human body. Generally, the heating temperature required for hyperthermia is about 42.5°C, and the temperature is kept warm for not less than 45 minutes. Too high temperature can easily damage normal cells of the human body. If the temperature is too low, the ideal tumor treatment effect cannot be achieved. Based on the electromagnetic induction phenomenon, the AC electromagnetic field generated by the transmitting coil will be transmitted to the metal coil 2 by electromagnetic radiation. When the metal coil 2 is near the transmitting coil, it will be affected by electromagnetic induction, induce a corresponding current, and then make the metal coil 2 generate heat. At the same time, according to Faraday's law of electromagnetic induction, the number of windings of the coil, the current intensity, the distance between the two coils and other parameters are known, and the heat generation of the metal coil 2 can be controlled by controlling the current intensity of the magnetic field transmitting module on the fixing part 5. At the same time, the temperature in the cavity is monitored in real time by a temperature sensor to ensure that the hyperthermia conditions are met. When in use, the fastener 5 of the belt structure is convenient to wear on the human body, and the fastener 5 can be close to the skin, so that the distance between the two coils changes relatively little during each thermal therapy. At the same time, the magnetic field generating module is as close as possible to the thermal therapy floatation device implanted in the human body to reduce magnetic field attenuation.

[0043] In another embodiment, Figure 4 As shown, a placement rod for a wireless tumor thermal therapy floatation device is also proposed, which includes a rod body 6 and an electromagnet 7 arranged at the end of the rod body 6. At this time, the housing 1 needs to be improved adaptively: a docking slot is arranged on the outside of one end of the housing 1, and a magnet 4 is connected to the docking slot. The electromagnet 7 is used to attract the magnet 4 after power is turned on. By attracting and fixing the magnet 4, the rod body 6 can be easily moved and placed in the wireless tumor thermal therapy floatation device. Specifically, as Figure 5As shown, one end of the rod body 6 is provided with a docking head that matches the docking slot at the rear end of the shell 1. The purpose of designing the docking head and the docking slot is to play a guiding role, so that the end of the rod body 6 can correspond to the rear end of the shell 1, which is convenient for the subsequent adsorption of the electromagnet 7. The electromagnet 7 is arranged on the docking head. A corresponding power supply and switch are arranged at one end of the rod body 6 away from the docking head. The switch controls the opening and closing of the electromagnet 7 to achieve the fixation and separation of the thermotherapy floatation device by the rod body 6. The thermotherapy floatation device can be sent into the bladder through the urethra by using the placement rod, or the thermotherapy floatation device can be sent into different parts of the human intestine, female reproductive cavity, etc. by the placement rod to achieve tumor thermotherapy. Further, in order to facilitate the attraction and fixation of the placement rod and the shell 1. The position of the airbag can be designed so that the average density of the thermotherapy floatation device close to the end of the magnet 4 is slightly smaller, and the average density of the other end is slightly larger. For example, when the thermal therapy floatation device is used in the bladder, the end of the thermal therapy floatation device close to the magnet 4 faces downward when floating, so as to facilitate docking with the placement rod entering from the urethra.

[0044] In another embodiment, a wireless tumor thermal therapy component is also proposed, which includes the tumor pulse thermal therapy system and the placement rod in the above embodiment. First, the thermal therapy float is sent into the tumor site of the human body through the placement rod, and then the placement rod is withdrawn from the human body, and the thermal therapy float is heated to the set temperature by the pulse heating device. During each thermal therapy, thermal therapy can be achieved by wearing a pulse heating device, so there is no need to repeatedly insert the device into the human body during each thermal therapy as in the traditional way, avoiding causing great pain to the patient. In addition, the size of the wireless tumor thermal therapy float can be 18mm long and 6mm in diameter. It is small in size and low in cost. It can be designed to be disposable and thrown away after use to prevent subsequent contamination.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
