Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an adapter and a tumor electric field therapy device. Background Technology

[0002] Tumor electric field therapy (TEF) has been used for medical purposes as a physical therapy method for many years. It involves generating a low-intensity, mid-to-high frequency, alternating electrical signal using an electric field generator to interfere with the mitotic process of tumor cells. Studies have shown that TGF-β therapy is significantly effective in treating glioblastoma, non-small cell lung cancer, and malignant pleural mesothelioma, affecting microtubule aggregation, preventing spindle formation, inhibiting mitosis, and inducing apoptosis in cancer cells.

[0003] An electric field generator, via an electrically connected adapter, transmits its generated alternating electrical signals to several pairs of electrode patches electrically connected to the adapter, thereby creating an alternating electric field between each pair of electrode patches. The paired electrode patches are applied to the corresponding areas of the patient's body surface to provide electric field therapy to the tissue area where the lesion is located. The adapter has corresponding sockets for each electrode patch, and each socket also has a corresponding indicator strip. The indicator strip displays different information through different display states of its corresponding LEDs, such as indicating the connection status of the socket and the electrode patch, or indicating certain fault information. However, the existing indicator strips have the following problem: when some indicator strips have LEDs lit and others have LEDs off, the light emitted by the lit indicator strips can scatter onto adjacent indicator strips whose corresponding LEDs are off, causing light transmission and leading to user misjudgment. In addition, the indicator strip is usually illuminated by a single LED corresponding to the indicator strip. Since a single LED is a point light source, when the indicator strip needs to provide light for a large indicator area, the light emitted by the single LED can easily cause uneven light distribution within the indicator strip during the scattering process, affecting the user's judgment.

[0004] Therefore, it is necessary to improve the adapters of existing tumor electric field therapy devices to solve the above problems. Utility Model Content

Detailed Implementation

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples consistent with some aspects of this application.

[0029] refer to Figure 1 As shown, a tumor electric field therapy device 400 according to one embodiment of this application includes an electric field generator 200, paired electrode patches 300, and an adapter 100 electrically connecting the electric field generator 200 and the paired electrode patches 300. The electrode patches 300 are applied to the epidermis corresponding to the tumor site of the patient. The alternating electric signal generated by the electric field generator 200 is transmitted to the paired electrode patches 300 through the adapter 100 to form an alternating electric field acting on the tumor site of the patient between the paired electrode patches 300, thereby performing electric field therapy. This application mainly improves the adapter 100.

[0030] refer to Figure 2 , Figure 3 and Figure 4As shown, the adapter 100 includes an upper shell 1, a bottom shell 2 assembled and fixed to the upper shell 1, several light guides 3, a PCB assembly 4, a cable 5 connected to the PCB assembly 4, a panel 6, and a label 7. The upper shell 1 and the bottom shell 2 are assembled together to form the housing (unlabeled) of the adapter 100. The housing (unlabeled) has two sets of paired snap-fit ​​components (unlabeled). Each set of snap-fit ​​components (unlabeled) includes a hook 12 and a snap-fit ​​part 22. Specifically, the upper shell 1 and the bottom shell 2 are both roughly rectangular boxes. The upper shell 1 has a hook 12 on each of its left and right inner walls, and the bottom shell 2 has a snap-fit ​​part 22 on each of its left and right inner walls, corresponding to the hook 12 of the upper shell 1. When the upper shell 1 and the bottom shell 2 are assembled, the two hooks 12 can snap into the corresponding snap-fit ​​parts 22, thereby fixing the upper shell 1 and the bottom shell 2 together. The housing (unlabeled) has an internal cavity (unlabeled) for accommodating the light guide 3 and the PCB assembly 4. The PCB assembly 4 includes a motherboard 41 and several sockets 40 electrically connected to the motherboard 41. The motherboard 41 is horizontally fixed inside the cavity (unlabeled) of the housing (unlabeled), and several LED beads 411 are provided on its side facing the upper shell 1. Several light-transmitting grooves 13 are provided on the upper shell 1, corresponding one-to-one with the LED beads 411 and used to transmit the light from the LED beads 411. The sockets 40 are all located at the front of the adapter 100 and exposed at the front end of the adapter 100 for electrical connection with the corresponding electrode patch 300; the cable 5 is electrically connected to the motherboard 41 and extends out of the adapter 100 from the rear end of the adapter 100 for electrical connection with the electric field generator 200. In this embodiment, the adapter 100 has four sockets 40. The insertion surfaces (unlabeled) of the four sockets 40 are arranged in a row and are all exposed at the front end of the adapter 100. The four sockets 40 can be divided into two groups, and each group of sockets 40 is inserted into a corresponding pair of electrode patches 300 to generate alternating electric fields in different directions between different electrode patches 300. Correspondingly, in this embodiment, there are four LED beads 411, which are respectively arranged in one-to-one correspondence with the four sockets 40. Similarly, there are also four light-transmitting slots 13 on the upper shell 1, which are respectively arranged in one-to-one correspondence with the four LED beads 411.

[0031] The upper shell 1 has a panel receiving groove 14 recessed downwards from its top for embedding the panel 6. The depth of the panel receiving groove 14 is close to the thickness of the panel 6. The panel 6 is provided with several indicator light bars 60 corresponding one-to-one with the light-transmitting grooves 13 of the upper shell 1. The light from the LED beads 411 can be emitted from the corresponding light-transmitting grooves 13 and illuminate the corresponding indicator light bars 60 to indicate the working status of the corresponding socket 40, such as whether the socket 40 is electrically connected to the electrode patch 300, or whether the electrode patch 300 electrically connected to the socket 40 is faulty. The size of the indicator light bars 60 is slightly smaller than the size of the light-transmitting grooves 13 so that the light emitted by the LED beads 411 can illuminate all the indicator light bars 60. In this embodiment, the four indicator light bars 60 are arranged in a row along the left-right direction of the panel 6, and each indicator light bar 60 is arranged in a strip shape extending along the front-back direction of the panel 6.

[0032] The bottom of the upper shell 1 also has several mounting portions 11 that protrude toward the main board 41 and correspond to each light-transmitting groove 13. After the adapter 100 is assembled, the mounting portions 11 of the upper shell 1 abut against the corresponding parts of the main board 41 so that each LED bead 411 protrudes into the corresponding mounting portion 11. In this embodiment, there are four mounting portions 11, each having a mounting groove 1110 formed by several light-blocking ribs 111 protruding downward from the bottom of the upper shell 1. The mounting portions 11 are roughly "U" shaped, and the mounting grooves 1110 are used to accommodate the light guide 3. The bottom of the upper shell 1 has several fixed recesses 110 that correspond to each of the multiple light-transmitting grooves 13. The fixed recesses 110 can cooperate with the corresponding parts of the light guide 3 to assemble the light guide 3 to the bottom of the upper shell 1. The several fixed recesses 110 are respectively located in the area surrounded by the light-blocking ribs 111 of the corresponding mounting portions 11.

[0033] refer to Figures 4 to 6 and Figure 8As shown, several light guides 3 are respectively assembled in the mounting grooves 1110 of each mounting part 11 of the upper shell 1, for guiding the light emitted by the LED beads 411 to the light-transmitting groove 13 and then through the panel 6 to the adapter 100. The light guides 3 are made of transparent light-guiding material, preferably acrylic material. The light guide 3 has a main body 30, which is a pentagonal plate shape that is larger at the top and smaller at the bottom and is approximately trapezoidal. Specifically, the main body 30 has a bottom surface 35 corresponding to the corresponding LED beads 411 and a top surface 36 corresponding to the corresponding fixed platform 110. Both the bottom surface 35 and the top surface 36 are parallel to the horizontal plane. The main body 30 has an irradiation part 31 that is recessed upward from its bottom surface 35 and is set in a stepped shape to accommodate the LED beads 411. The irradiation part 31 has an intersecting first irradiation surface 311 and a second irradiation surface 312. The main body 30 also has a first refractive surface 313 inclined downward from one end of its top surface 36 corresponding to the irradiation part 31, and a second refractive surface 314 inclined upward from one end of its bottom surface 35 away from the irradiation part 31. The angle between the first refractive surface 313 and the horizontal plane where the top surface 36 is located is approximately 45°±15°, and the angle between the second refractive surface 314 and the horizontal plane where the bottom surface 35 is located is approximately 30°~55°. Several light guides 3 also have extension portions 34 extending forward from the front end of their main body 30 and positioning portions 33 protruding upward from the top surface 36 of their main body 30 and corresponding one-to-one with the plurality of light-transmitting grooves 13. The thickness of the extension portion 34 is close to the depth of the fixed recess 110. The shape and size of the positioning portion 33 match the shape and size of the light-transmitting groove 13. After the adapter 100 is assembled, the main body 30 of the light guide 3 is placed in the mounting groove 1110 of the mounting part 11. The mounting part 11 abuts against the main board 41. The first irradiation surface 311 of the irradiation part 31 of the light guide 3 is located directly above the LED bead 411, and the second irradiation surface 312 of the irradiation part 31 is located directly in front of the LED bead 411. The angle between the first irradiation surface 311 and the second irradiation surface 312 is 90°±10°, preferably 90°. The positioning part 33 of the light guide 3 protrudes into the light-transmitting groove 13. The top surface 36 and the extension part 34 of the light guide 3 abut against the corresponding parts of the fixed platform 110. The left side surface 37, the right side surface 38, and the rear side surface 39 of the light guide 3 abut against the corresponding surfaces of the light-blocking ribs 111 of the mounting part 11 located in the mounting groove 1110, thereby completing the assembly of the light guide 3 and the mounting part 11 of the upper shell 1. The light guide 3 is sandwiched between the upper shell 1 and the main board 41. Because the mounting portion 11 is formed by three surrounding light-blocking ribs 111, and has an opening on its front side, each light-blocking rib 111 of the mounting portion 11 can limit the light guide 3 on three sides, preventing the light guide 3 from shaking. The fixed recess 110 prevents the light guide 3 from sliding out of the opening of the mounting portion 11, further limiting the light guide 3.The adapter 100 of this application can separate the light guides 3 from each other by setting the mounting part 11 of the upper shell 1, so as to prevent the light of the LED beads 411 from entering the adjacent light guides 3 and then passing through the adjacent light transmission groove 13, thereby affecting the judgment of the indicator effect of the LED beads 411. The thickness of the positioning part 33 of the light guide 3 does not exceed the depth of the light transmission groove 13, that is, the positioning part 33 does not protrude from the light transmission groove 13, so that the panel 6 can be placed flat in the panel receiving groove 14. Preferably, the top surface of the positioning part 33 is flush with the bottom surface of the panel receiving groove 14, so that the top surface of the positioning part 33 abuts against the panel 6, so that the light of the LED beads 411 is transmitted from the positioning part 33 to the corresponding indicator light strip 60 on the panel 6 and passes through. When the LED bead 411 is lit, the light entering from the first irradiation surface 311 and the second irradiation surface 312 can be internally refracted under the action of the first refractive surface 313 and the second refractive surface 314, and then conducted and concentrated to the positioning part 33 of the light guide 3 before being emitted, so that more light can pass through the light transmission groove 13 and enhance the indication function.

[0034] refer to Figure 7 As shown, the adapter 100 also includes a label 7 mounted on the bottom surface of the base 2. The base 2 has a first recessed platform 20 that is recessed upward from its bottom surface and matches the shape and size of the label 7. The depth of the recess is close to the thickness of the label 7, and the label 7 is directly embedded in the first recessed platform 20. The base 2 also has a second recessed platform 21 formed by continuing to recess upward from the bottom surface located at the first recessed platform 20, which is used to affix production date barcodes (not shown), etc., to facilitate the flexibility and convenience of subsequent production operations.

[0035] The adapter 100 of this application fixes the light guide 3 by providing multiple mounting portions 11 inside its housing (not shown) to accommodate the light guide 3. This ensures the stable and reliable assembly of the adapter 100 by clamping the light guide 3 between the upper housing 1 and the PCB assembly 4, preventing the light guide 3 from falling off during the initial assembly process of the adapter 100. The mounting portions 11 can also separate each light guide 3 and LED beads 411 from each other, preventing the light transmitted by each light guide 3 from entering other adjacent light-transmitting slots 13 and illuminating other indicator light bars 60, thus avoiding confusion in the indication effect. This allows the light of the LED beads 411 to be optically transmitted directly through the light guide 3 located in the mounting portion 11 of the housing, thereby enhancing the light focusing ability of the LED beads 411 in their corresponding optical paths and improving the indication effect.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
