Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a low-frequency electrotherapy breast physiotherapy device based on regional alternating moisturization. Background Technology

[0002] Low-frequency electrotherapy, as a physical therapy method, has been widely used in breast health care, adjunctive treatment of mastitis, and postoperative rehabilitation of breast cancer. Its basic principle is to apply low-frequency pulsed current to breast tissue through electrode pads, stimulating neuromuscular nerves, promoting local blood circulation and lymphatic drainage, thereby relieving pain, reducing edema, and preventing breast-related complications.

[0003] Currently available low-frequency electrotherapy devices for breast cancer typically use flexible electrode patches or integrated cup structures, with the electrode patches directly attached to the surface of the breast skin. When using these devices, the electrode patches are fixed to the same skin area for an extended period, continuously discharging. This can cause the moisture in the local stratum corneum to gradually evaporate, leading to increased skin resistance and resulting in stinging, burning, or even needle-like discomfort.

[0004] To address these issues, some existing technologies integrate humidification functions into electrotherapy devices. For example, moisturizing pads, hydrogel layers, or microporous humidification structures are added around or adjacent to the electrode pads to simultaneously moisturize the skin during electrotherapy.

[0005] However, in this design, the positions of the moisturizing pad and the electrode pad are relatively fixed. The humidification area is always located around the periphery of the electrode pad, while the central area of ​​the skin directly in contact with the electrode pad cannot effectively penetrate moisture and remains insufficiently moisturized. Furthermore, with the electrode pad covering the same area of ​​skin for extended periods, even with a surrounding moisturizing layer, the rate of moisture loss in that localized area due to continuous heat and electrical stimulation still exceeds the rate of hydration, resulting in dryness and stinging. This dryness is particularly pronounced in scenarios requiring prolonged treatment, such as during sleep at night, impacting patient compliance and treatment effectiveness.

[0006] Therefore, existing technologies still present the technical problem of causing dryness and stinging in localized skin areas after prolonged low-frequency electrotherapy. Summary of the Invention

[0007] The purpose of this invention is to provide a low-frequency electrotherapy breast physiotherapy device based on regional alternating moisturization, so as to solve the technical problem in the prior art that the moisturizing position is misaligned with the electrotherapy position, resulting in insufficient moisturizing intensity and dryness and stinging during long-term physiotherapy.

[0008] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A low-frequency electrotherapy breast physiotherapy device based on regional alternating moisturization includes a carrier plate that can be set at the chest position via an adjustable strap; A rigid base plate is coaxially and reciprocally mounted on the surface of the carrier plate. The center of the rigid base plate is recessed to form a groove structure that conforms to the contour of the breast so as to cover the outside of the breast. Multiple electrode plates and multiple moisturizing areas are formed on the surface of the rigid base plate. The multiple electrode plates and multiple moisturizing areas are arranged alternately in a circumferential array on the surface of the rigid base plate. Electrode plates and moisturizing areas are respectively provided on the electrode plates and the moisturizing areas. The rigid base plate rotates axially to drive all the electrode pads and the moisturizing pads to rotate synchronously, so as to move the electrode pads to the local skin position that has been moistened by the adjacent moisturizing pads. Furthermore, an annular water storage box is provided on the outer circumferential edge of the carrier plate, and multiple water outlets are arranged circumferentially on the inner circumferential wall of the annular water storage box facing the center of the carrier plate. A water tank is provided on the rigid base plate at the location of the moisturizing area. The water inlet of the water tank is provided on the ring-shaped stopper. The ring-shaped stopper is formed circumferentially on the outer circumferential edge of the rigid base plate, and the outer circumferential wall of the ring-shaped stopper with the water inlet is attached to the inner circumferential wall of the annular water storage box with the water outlet. When the ring-shaped rocker plate rotates along the inner wall of the annular water storage box and the water inlet is connected to the water outlet on the annular water storage box, the annular water storage box fills the water tank with water to moisten the moisturizing sheet.

[0009] In one embodiment of the present invention, the surface of the carrier plate connected to the rigid base plate is constructed in reverse according to the outer contour of the rigid base plate to connect with the rigid base plate, and the rigid base plate rotates axially in an embedded position within the carrier plate.

[0010] In one embodiment of the present invention, a hemispherical shell is connected to the side of the carrier plate away from the rigid base plate, and there is a cavity between the carrier plate and the hemispherical shell. The hemispherical shell is positioned at the chest position by the adjustment strap to fix the rigid base plate onto the breast.

[0011] In one embodiment of the present invention, the surface of the carrier plate has a plurality of arc-shaped perforations arranged axially. A clamping slider is slidably disposed in the arc-shaped perforations. One side of the clamping slider is fixedly connected to the rigid base plate, and the other end is connected to a connecting rod. The multiple connecting rods are disposed in the cavity and extend toward the center of the carrier plate, and are connected to a drive source for inputting rotational torque to drive the rigid base plate to rotate axially.

[0012] In one embodiment of the present invention, the annular water storage box is connected to an airbag assembly that pressurizes its interior.

[0013] In one embodiment of the present invention, the airbag assembly includes an airbag fixedly disposed on the back of the carrier plate and a connecting pipe connecting the airbag and the annular water storage box. A movable perforation is provided on the carrier plate on one side of the airbag. A pressure block is slidably disposed inside the movable rotating plate. The pressure block is fixedly disposed on the rigid base plate to slide with the rigid base plate. When the water inlet of the ring plug is aligned and connected with the water outlet on the annular water storage box, the pressure block squeezes the airbag to inflate and pressurize the annular water storage box.

[0014] In one embodiment of the present invention, a rubber strip is provided on one side of the water tank inlet of the ring-shaped rocker plate, and an avoidance hole is provided on the rubber strip to avoid the water inlet. The ring-shaped rocker plate is pressed against the annular water storage box by the rubber strip to block the water outlet of the annular water storage box.

[0015] In one embodiment of the present invention, the diameter of the inlet on the ring-shaped rocker plate is larger than the diameter of the outlet on the annular water storage box, and absorbent cotton is provided on the rubber strip around the clearance hole.

[0016] Compared with the prior art, the present invention has the following advantages: This invention utilizes a rigid base plate with staggered moisturizing pads and electrode pads. The rigid base plate drives the moisturizing pads and electrode pads to rotate alternately, ensuring that the electrode pads are always positioned where the previous moisturizing pad has just been moistened during electrotherapy. This guarantees that each treatment is conducted in a moist environment, significantly improving the uniformity and continuity of hydration in the treatment area. Simultaneously, the moisturizing pads automatically connect with the annular water reservoir during advancement, pre-moistening the area for the next round of electrotherapy, forming a continuous moist cycle. This effectively avoids skin stinging caused by prolonged local dryness during electrotherapy, improving treatment comfort and enhancing targeted hydration of the target area.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1 Figure 8 As shown, the present invention provides a low-frequency electrotherapy breast physiotherapy device based on regional alternating moisturizing, comprising: Carrier plate 1 can be positioned at the chest level via adjustable strap 2, such as... Figure 1 and Figure 8 As shown.

[0023] like Figure 1As shown, a rigid base plate 3 is coaxially and reciprocatingly mounted on the surface of the carrier plate 1. The rigid base plate 3 has a concave center forming a groove structure that conforms to the contour of the breast to cover the breast as a whole. The carrier plate 1 may have an adjustment strap 2 connected to its edge. After the adjustment strap 2 passes around the patient's chest and back, it fixes the carrier plate 1 to the chest, making it stably cover the breast. Specifically, as a preferred embodiment, a hemispherical shell 11 is connected to the side of the carrier plate 1 away from the rigid base plate 3. There is a cavity 12 between the carrier plate 1 and the hemispherical shell 11. The hemispherical shell 11 is positioned at the chest position by the adjustment strap 2 to fix the rigid base plate 3 to the breast.

[0024] Among them, such as Figure 1 As shown, the hemispherical shell 11 is hollow inside and has a sheet-like shape with an opening on one side. The opening connects to the carrier plate 1. The surface of the carrier plate 1, which is connected to the rigid base plate 3, is constructed with a groove structure in reverse according to the outer contour of the rigid base plate 3 to connect with the rigid base plate 3. The rigid base plate 3 rotates axially in an embedded position within the carrier plate 1. The rigid base plate 3 is concave in the middle and extends outward in the outer area to increase the contact area with the patient's breast. Two hemispherical shells 11 can be provided and connected by an adjustment strap 2. The adjustment strap 2 positions the inner hemispherical shell 11 at the patient's chest position, and the carrier plate 1 is pressed against the patient's breast, so that the arc-shaped surface of the carrier plate 1 (the groove and the outer periphery of the groove) can contact the mammary gland. The surface of the carrier plate 1 forms a conforming treatment area.

[0025] like Figure 3 As shown, multiple electrode pads 4 and multiple moisturizing pad areas 5 are formed on the surface of the rigid base plate 3 in the treatment area. The electrode pads 4 and multiple moisturizing pad areas 5 are arranged alternately, and the electrode pads 4 and moisturizing pad areas 5 are arranged in a circumferential array on the surface of the rigid base plate 3. Electrode pads 6 and moisturizing pads 7 are respectively provided on the electrode pads 4 and moisturizing pad areas 5. The axial rotation of the rigid base plate 3 drives all electrode pads 6 and moisturizing pads 7 to rotate synchronously, so as to move the electrode pads 6 to the local skin position moistened by the adjacent moisturizing pads 7.

[0026] After a period of electrotherapy, the electrode 6 can move to the position of the moisturizing pad 7, and the moisturizing pad 7 can move to the position of another adjacent electrode 6, so that the electrode 6 can perform electrotherapy on the skin directly moistened by the moisturizing pad 7, thereby improving the therapeutic effect and user comfort.

[0027] Furthermore, this device provides a specific rotating connection structure between the rigid base plate 3 and the carrier plate 1, which limits the rotation angle of the rigid base plate 3, reduces friction on the skin surface, and improves the practicality of the device. Specifically, as shown... Figure 2 and Figure 7As shown, the surface of the carrier plate 1 has multiple arc-shaped perforations 13 arranged axially. A clamping slider 14 is slidably disposed within each arc-shaped perforation 13. The extension trajectory of the arc-shaped perforation 13 is arc-shaped, and the center line of this arc-shaped trajectory is coaxially arranged with the inner hemispherical bracket. The slider, which may include two wings, clamps the edge of the arc-shaped perforation 13, causing the slider to slide back and forth along the arc-shaped trajectory of the arc-shaped perforation 13. One side of the clamping slider 14 is fixedly connected to the rigid base plate 3, and the other end is connected to a connecting rod 15. Multiple connecting rods 15 are disposed within the cavity 12 and extend towards the center of the carrier plate 1, converging to form a control rod. The control rod is connected to a drive source 17 that inputs rotational torque to drive the rigid base plate 3 to rotate axially. The drive source 17 can be a manually operated grip, as shown, or an electric drive source 17.

[0028] In this structure, the slider only needs to rotate a small angle (divided by the sum of the number of electrode pads 6 and moisturizing pads 7) each time to rotate the electrode pad 6 onto the skin moistened by the moisturizing pad 7. For example, if the sum of the number of electrode pads 6 and moisturizing pads 7 is 1, then the drive structure only needs to control the slider's sliding angle along the perforation trajectory to rotate the electrode pad 6 from its original position to the downstream moisturizing pad 7. Each downstream electrode pad 6 and moisturizing pad 7 moves down sequentially, changing positions to perform electrotherapy and moisturizing respectively.

[0029] When rotating to change positions again, there's no need to rotate in the same direction; instead, the rotation is reversed, moving the slider back to its initial position. At this point, electrode 6 returns to its initial position, which was moistened by the upstream moisturizing pad 7 during the previous operation. Therefore, this implementation method can achieve moisturization of various areas of the breast skin through reciprocating rotation at small angles.

[0030] The power supply and control unit of electrode plate 6 in this device is a mature structure in the prior art, and the arrangement of its internal components is also a mature arrangement, which has been successfully applied in existing breast enhancement devices, breast health shields, breast treatment instruments, and other related equipment. For example, it can have a similar internal circuit component arrangement as in patents with patent numbers CN202021381394.7, CN201920675095.5, and CN201611243152.X, entitled "A Breast Physiotherapy and Tumor Treatment Device, a Breast Treatment Instrument, and a Device for a Low-Frequency Electromagnetic Breast Health Shield Based on Micro-Bioelectromagnetic Stimulation".

[0031] This embodiment further provides a specific connection structure, arrangement relationship and arrangement position of the electrode sheet 6 and its power supply component, in order to ensure that this application is fully disclosed. However, it should be understood that this method is only one implementation method of the electrode sheet 6 wiring harness, power supply and control element. There are still a large number of other arrangement forms in the prior art, which will not be listed and described in this application.

[0032] Specifically, a through hole is made at the center of the rigid base plate 3 and the carrier plate 1 (the diameter of the through hole can be relatively large to avoid the patient's nipple). A groove is made at the edge of the through hole, and the flexible lead of the electrode plate 6 is fixedly set in the groove, so that the flexible lead can remain in place during rotation, and the flexible lead will not be pulled even if the rigid base plate 3 rotates at a small angle.

[0033] Additionally, the electrode pad 6 can be connected to a control element, which includes a pulse generating unit and a current amplification unit electrically connected in sequence between the miniature power supply and the electrode pad 6. The pulse generating unit generates low-frequency or modulated intermediate-frequency pulse signals with adjustable frequency and intensity. The current amplification unit amplifies the pulse signal to the output amplitude required for physiotherapy. The pulse generating unit and current amplification unit can be implemented using circuit structures known in the field of intermediate-frequency electrotherapy devices. The control element can also be integrated with the miniature power supply into a single control assembly. A hemispherical shell 11 is provided outside the carrier plate 1, and the overall control assembly is directly disposed within the cavity 12 of the hemispherical shell 11. Furthermore, buttons and a display screen can be integrated into the control assembly according to actual usage, embedding them on the outer surface of the hemispherical shell 11, thus enhancing the overall practicality of the device.

[0034] Furthermore, since the moisturizing pad 7 remains moist during rotation, the surface moisture also acts as a lubricant, further reducing friction during rotation and making the movement of the electrode pad 6 and the moisturizing pad 7 more comfortable. Moreover, it is known in the art that using the electrode pad 6 to move on the skin in a physiotherapy device is a mature technology. For example, the technical solution disclosed in patent CN202180036585.0, which states that "both the first RF electrode and the second RF electrode can move relative to the base of the application head...so that a part of the skin comes into contact with one or more application heads"; the technical solution disclosed in patent CN201320789202.X, which states that "the driving device drives the head cover to rotate, automatically changing the electrotherapy position"; and the technical means in patent CN96102476.3, which "provides an intelligent, portable, low-frequency physiotherapy electrode that allows the electrode to move freely to any permissible location on the human body during treatment without causing electric shock, and is convenient and safe to use," all demonstrate that the movement of the electrode pad 6 on the skin surface can be fully and reasonably implemented.

[0035] In this embodiment, further, such as Figure 1 , Figure 2 and Figure 7 As shown, an annular water storage box 8 is provided on the outer circumferential edge of the carrier plate 1. Multiple water outlets 16 are arranged circumferentially on the inner circumferential wall of the annular water storage box 8 facing the center of the carrier plate 1. The annular water storage box 8 is used to store pure water or therapeutic fluid (such as physiological saline) needed to moisturize the skin.

[0036] A water trough 9 is provided on the rigid base plate 3 in the moisturizing area, such as... Figure 3 As shown, the water tank 9 is designed as a zigzag water tank 9, which covers the entire projected area of ​​the moisturizing sheet 7 to increase the water diffusion area. The water inlet 24 of the water tank 9 is set on the annular stopper 10, which is circumferentially formed on the outer circumferential edge of the rigid base plate 3, and the outer circumferential wall of the annular stopper 10 with the water inlet 24 abuts against the inner circumferential wall of the annular water storage box 8 with the water outlet 16. The annular stopper 10 can rotate with the rigid base plate 3, and its outer wall maintains a sliding sealing contact with the inner wall of the annular water storage box 8.

[0037] Among them, such as Figure 6 As shown, when the annular rocker arm 10 rotates along the inner wall of the annular water storage box 8 and the inlet 24 connects with the outlet 16 on the annular water storage box 8, water is injected into the water tank 9 to moisten the moisturizing sheet 7. When the inlet 24 and the outlet 16 are misaligned, the outer wall of the annular rocker arm 10 will seal the outlet 16 to prevent leakage. This allows for intermittent water replenishment, preventing the moisturizing sheet 7 from drying out and keeping it continuously moist.

[0038] Example 2

[0039] Furthermore, such as Figure 7 As shown, based on Embodiment 1, to facilitate the filling of the annular water storage box 8 with water and the humidifying pad 7 into the water tank 9, this embodiment further connects the annular water storage box 8 to an airbag assembly 18 that pressurizes its interior. The airbag assembly 18 maintains pressure within the annular water storage box 8, allowing water to automatically enter the water tank 9 when the inlet 24 and outlet 16 are aligned. This method can be manually controlled or automatically controlled to expand and compress the airbag 19.

[0040] Furthermore, a specific structure is provided so that each time the rigid base plate 3 rotates, its automatic compression airbag 19 adds water to the water tank 9, improving the ease of use.

[0041] The airbag assembly 18 includes an airbag 19 fixedly disposed on the back of the carrier plate 1 and a connecting pipe 20 connecting the airbag 19 and the annular water storage box 8.

[0042] A movable perforation 21 is provided on one side of the airbag 19 on the carrier plate 1. A pressure block 22 is slidably disposed within the movable perforation 22. The pressure block 22 is fixedly disposed on the rigid base plate 3 to slide with the rigid base plate 3. When the inlet 24 of the annular stopper 10 is aligned with the outlet 16 on the annular water storage box 8, the pressure block 22 precisely squeezes the airbag 19 to inflate and pressurize the annular water storage box 8. The annular water storage box 817 itself can be made of an elastic material (such as silicone or rubber) or a rigid plate connected to one side of the annular stopper 10, while the other sides are made of an elastic material. This gives it deformability and resilience. When the airbag 19 is inflated, the gas enters the sealed cavity of the annular water storage box 817, pushing the liquid out of the outlet 1618.

[0043] Example 3

[0044] like Figure 6 As shown, a rubber strip 23 is provided on one side of the water inlet 24 of the water tank 9 on the ring-shaped rocker plate 10. The rubber strip 23 has a clearance hole to avoid the water inlet 24. The ring-shaped rocker plate 10 is pressed against the annular water storage box 8 by the rubber strip 23 to seal the water outlet 16 of the annular water storage box 8. The rubber strip 23 plays a sealing role to prevent water from leaking from the mating gap when the connection is not open.

[0045] The diameter of the inlet 24 on the ring-shaped rocker plate 10 is larger than the diameter of the outlet 16 on the annular water storage box 8. This ensures that even with slight misalignment, the outlet 1618 can fall completely within the range of the inlet 2415, guaranteeing smooth water flow. Furthermore, absorbent cotton 25 is provided on the rubber strip 23 around the clearance hole. The absorbent cotton 25 can absorb any small amount of water that may overflow when the outlet 16 and the inlet 24 are joined, preventing the liquid from flowing along the surface of the ring-shaped rocker plate 10 to other areas.

[0046] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
