Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a heatable electrode patch. Background Art
[0002] A neuromuscular low-frequency electrical stimulator is a stimulator that uses specific low-frequency pulsed current to act on the human body for treatment. By stimulating denervated muscles, it reduces muscle fiber degeneration, slows down muscle denervation atrophy, promotes blood flow and maintains muscle nutrition, promotes hypertrophy and strengthening of denervated muscles and muscle fibers reinnervated by nerves, and quickly increases muscle tension.
[0003] The neuromuscular system is a complex system composed of the nervous system and the muscular system. It controls the movement and coordination of muscles by transmitting nerve signals, enabling people to perform various activities and movements. The following are the main components and functions of the neuromuscular system.
[0004] Low-frequency electrical stimulation is a medical treatment method that stimulates nerves and muscles by transmitting low-frequency current in human tissues to treat various diseases and symptoms. Low-frequency electrical stimulation usually uses special electrode patches or electrode devices to transmit the current to specific parts of the patient's body.
[0005] The existing heatable physiotherapy electrode patch includes a first outer shell, the lower surface of the first outer shell is attached to the upper surface of the second outer shell, a plurality of first clamping blocks are fixedly connected to the lower surface of the bottom end of the first outer shell, a pulling block is fixedly connected to the top end of the slider, a third conductor is fixedly connected to the middle position of the slider, the left and right ends of the third conductor are respectively attached to the second conductor and the conductive block, the right end of the conductive block is fixedly connected to the inner core of the wire, and a wire is fixedly connected to the right end of the first outer shell. For this heatable physiotherapy electrode patch, through the cooperation of the first clamping blocks, the first clamping grooves and the inner groove, the second outer shell can be separated from the first outer shell, so that the inner groove is exposed, and then the replacement of the voltage-sensitive conductive film is realized. Through the cooperation of the pulling block, the slider, the sliding groove and the third conductor, the pulling block can drive the slider and the third conductor to slide along the sliding groove, so as to control the operation of the electric heating sheet.
[0006] When the existing physiotherapy electrode patch is actually used, although it is very convenient to replace the voltage-sensitive conductive film, the voltage-sensitive conductive film needs to be made into a fixed shape to be adapted, which is not convenient to use; when in use, it is often necessary to adsorb and fix the electrode patch on the patient's body, and the relatively cold electrode patch is likely to cause irritation to the patient and cause discomfort to the patient; during the use process, the wires of the electrode patch will be entangled, which is not convenient for the wires to be unfolded and used.

[0033] The heatable electrode patch provided by the present utility model is used for a neuromuscular low-frequency electrical stimulator, and includes a suction cup 1 with an installation groove 5 on the inner wall, a heating wire 6 installed in the installation groove 5, an electrode patch 7 installed on the suction cup 1, and a patch 9 connected to the electrode patch 7. The outer periphery of the electrode patch 7 has a limiting block 8. The through hole of the patch 9 is sleeved on the electrode patch 7 and is clamped with the limiting block 8. The patch 9 covers the surface of the heating wire 6, and the heating wire 6 is used to heat the electrode patch 7 and the patch 9.
[0034] In the above structure, the heatable electrode patch includes a suction cup 1, a heating wire 6, an electrode patch 7, and a patch 9. The electrode patch 7 is installed on the suction cup 1, the patch 9 is connected to the electrode patch 7, the outer periphery of the electrode patch 7 has a limiting block 8, and the patch 9 has a through hole. The through hole of the patch 9 is sleeved on the electrode patch 7. The patch 9 only needs to be provided with a round hole in the middle, which is more convenient for production and processing. The patch 9 is clamped with the limiting block 8. The patch 9 is clamped between the electrode patch 7 and the limiting block 8, and the limiting block 8 limits and fixes the patch 9 to realize the connection between the electrode patch 7 and the patch 9. The suction cup 1 deforms by means of the outer ring part and can directly adsorb and fix the device in a suitable position, so as to ensure that the patch 9 can fit on the body surface of the patient. The patch 9 fits on the skin of the patient to ensure the contact stability of the electrode patch 7.
[0035] The inner wall of the suction cup 1 has an installation groove 5, and the heating wire 6 is installed in the installation groove 5. The installation groove 5 installs and fixes the heating wire 6. The heating wire 6 is received in the inner side wall of the installation groove 5, and the patch 9 covers the surface of the heating wire 6. The heating wire 6 does not directly contact the skin of the patient. The patch 9 is sleeved on the electrode patch 7, and then the heating wire 6 is started. The heating wire 6 heats up the patch 9 and the electrode patch 7, and the hot patch 9 and electrode patch 7 are attached to the body surface of the patient, so as to reduce the discomfort caused by the cooler temperature when attached to the patient's body, and further avoid the stimulation of the cooler temperature to the patient.
[0036] On the basis of the above various specific embodiments, the suction cup 1 is provided with an exhaust hole 2, a drainage tube 3 is connected in the exhaust hole 2, and the end of the drainage tube 3 is detachably connected to a sealing cover 4.
[0037] In a specific embodiment, the arrangement of the exhaust hole 2 can introduce gas into the suction cup 1 through the exhaust hole 2 after negative pressure appears inside the suction cup 1, so that the air pressure inside the suction cup 1 is balanced with the outside world, and it is convenient to remove the device from the patient's body.
[0038] Through the arrangement of the drainage tube 3, exhaust can be carried out by means of the exhaust grooves provided on the surface of the drainage tube 3, and exhaust can also be carried out by means of the end of the drainage tube 3. After exhausting, the sealing cover 4 is covered on the exhaust groove, and the sealing cover 4 can ensure the sealing performance of the drainage tube 3, thereby ensuring the adsorption stability of the suction cup 1.
[0039] Based on the above various specific embodiments, the side wall of the end of the drainage tube 3 is provided with ventilation holes, and the connection length between the sealing cover 4 and the end of the drainage tube 3 is adjustable. Adjusting the connection length can adjust the area of the ventilation holes blocked by the sealing cover 4.
[0040] In a specific embodiment, the sealing cover 4 and the end of the drainage tube 3 have a set connection length. At the rated connection length, the sealing cover 4 completely blocks the ventilation holes, isolating the gas inside and outside the suction cup 1, ensuring the sealing performance of the suction cup 1, and thus ensuring the adsorption stability of the suction cup 1. By adjusting the connection length between the sealing cover 4 and the end of the drainage tube 3, the area of the ventilation holes blocked by the sealing cover 4 can be changed, that is, the gas flow area inside and outside the suction cup 1 can be changed, and a small amount of exhaust can be carried out. Therefore, when the adsorption is too tight, gas can be inhaled through the ventilation holes on the outside of the drainage tube 3, thereby alleviating the tightness of the adsorption of the suction cup 1.
[0041] Preferably, the sealing cover 4 is threadedly connected to the drainage tube 3. The sealing cover 4 is threadedly connected to the surface of the drainage tube 3, and then the sealing cover 4 is rotated to adjust the connection length, which is convenient for adjustment.
[0042] In a preferred embodiment, the side wall of the end of the drainage tube 3 is provided with a plurality of ventilation holes along the axial direction, and the connection length between the sealing cover 4 and the end of the drainage tube 3 is adjustable to change the number of ventilation holes blocked by the sealing cover 4.
[0043] Based on the above various specific embodiments, the interior of the suction cup 1 includes a central electrode area, a heating area located on the outer periphery of the central electrode area, an exhaust area located on the outer periphery of the heating area. The electrode sheet 7 is connected to the central electrode area, the installation groove 5 is provided in the heating area, the exhaust hole 2 is provided in the exhaust area, and an intermediate support ring equal in height to the outer ring of the suction cup 1 is provided in the exhaust area.
[0044] In a specific embodiment, the electrode sheet 7 is located in the central electrode area, the treatment point is in the central position, and it diverges from the center to the periphery, with a uniform treatment effect. The heating wire 6 is located on the outer periphery of the electrode sheet 7, and the patch 9 covers the surface of the heating wire 6. Preferably, the patch 9 has the same diameter as the heating wire 6. The heating wire 6 completely covers the heating range of the heating wire 6 and the patch 9, and the patch 9 completely blocks the range of the heating wire 6, which can not only ensure uniform heating but also ensure that the heating wire 6 does not directly contact the skin and cause skin burns. The exhaust area is located on the outer periphery of the heating area, reducing the influence of temperature on the adsorption performance of the suction cup 1 and ensuring the adsorption stability of the suction cup 1.
[0045] The exhaust area is provided with an intermediate support ring. The intermediate support ring has the same height as the outer ring of the suction cup 1 and is made of the same material as the outer ring of the suction cup 1. The intermediate support ring can also be deformed to directly adsorb and fix the device in a suitable position. The intermediate support ring and the outer ring of the suction cup 1 form an independent exhaust area, which can not only further reduce the influence of temperature on the adsorption of the suction cup 1, but also increase the adsorption area between the suction cup 1 and the skin, improving the adsorption stability of the suction cup 1.
[0046] On the basis of the above specific embodiments, a protective ring 10 is connected to the outer ring of the suction cup 1. The protective ring 10 is made of a relatively soft gel material, is U-shaped, and the opening of the protective ring 10 is fitted and clamped on the outer edge of the outer ring of the suction cup 1.
[0047] In a specific embodiment, the protective ring 10 is made of a relatively soft gel material and fits on the outermost ring of the suction cup 1. It can not only ensure the adsorption stability of the suction cup 1, but also has a relatively soft texture and is not easy to damage the skin when contacting the skin.
[0048] The opening of the U-shaped protective ring 10 is clamped on the outer ring of the suction cup 1 and is bonded to the outer ring of the suction cup 1 by its own adsorption, with a tight connection and not easy to separate.
[0049] On the basis of the above specific embodiments, the through hole of the patch 9 is a stepped hole. The body of the electrode sheet 7 is press-fitted on the stepped surface of the stepped hole. The surface of the body of the electrode sheet 7 is flush with the surface of the patch 9. There is no step between the electrode sheet 7 and the patch 9. When the electrode sheet 7 and the patch 9 contact the skin together, it is smooth and will not squeeze and damage the skin.
[0050] On the basis of the above specific embodiments, the limiting block 8 is a wedge-shaped block that gradually increases from one end close to the body to the end far from the body. When the patch 9 is separated from the connecting end of the electrode sheet 7, the patch 9 moves along the slope of the wedge-shaped block to the end far from the body, facilitating the disassembly and replacement of the patch 9.
[0051] On the basis of the above specific embodiments, it further includes a protective shell 11 connected to the outer surface of the suction cup 1. The electrical components and circuit ports of the electrode sheet 7 are placed inside the protective shell 11. The side wall of the protective shell 11 is provided with a wire passing hole for the wire 15 to pass through.
[0052] In a specific embodiment, through the setting of the protective shell 11, it can protect the electrical components and circuit ports required by the electrode sheet 7, and at the same time can also extend the wire 15 outwards for the wire 15 to be led out and connected.
[0053] On the basis of the above specific embodiments, the protective shell 11 is cylindrical. The outer part of the protective shell 11 is rotatably connected with a turntable 16. The side wall of the turntable 16 is provided with a guiding groove 17. The wire 15 passes through the guiding groove 17. By rotating the turntable 16, the guiding groove 17 winds the wire 15 around the outer periphery of the protective shell 11.
[0054] In a specific embodiment, the turntable 16 is cylindrical. The turntable 16 has a bottom surface with a hollowed-out upper surface. The bottom surface of the turntable 16 has a round hole that is directly sleeved on the surface of the protective shell 11. The round hole and the protective shell 11 are in clearance fit, and the turntable 16 and the protective shell 11 are rotatably connected. The protective shell 11 is used to assist the rotation of the turntable 16.
[0055] Through the guiding groove 17 provided on the outer side of the turntable 16, when the turntable 16 is rotated, the guiding groove 17 can be used to assist the sliding and guiding of the wire 15, and the wire 15 can be wound around the surface of the protective shell 11 in a rotating manner, so as to wind and store the wire 15 used in the device by hand. When in use, the turntable 16 can be rotated in the reverse direction to pull out the wire 15 for use, thereby enabling the user to unfold and use the device and fold and store it.
[0056] On the basis of the above various specific embodiments, a sliding groove 12 perpendicular to its axis is provided on the side wall of the protective shell 11. A clamping block 14 is connected in the sliding groove 12. The inner end of the clamping block 14 is connected inside the sliding groove 12, and the outer end is located outside the sliding groove 12. There is a gap between the bottom surface of the clamping block 14 and the surface of the suction cup 1. The round hole at the bottom surface of the turntable 16 is sleeved on the protective shell 11. The thickness of the bottom surface of the turntable 16 is equal to the height of the gap, and the bottom surface of the turntable 16 is clamped in the gap. Through the arrangement of the sliding groove 12 provided on the outer side of the protective shell 11, the compression spring 13 and the clamping block 14 are assisted to slide, so as to extend the clamping block 14 outwards to clamp and fix the turntable 16. The bottom surface of the turntable 16 is in tight fit with the gap to prevent the turntable 16 from rotating randomly and causing the wire 15 to be loosened.
[0057] A compression spring 13 is provided at the inner end of the clamping block 14, and a guiding column is provided at the bottom surface of the sliding groove 12. The compression spring 13 is sleeved on the guiding column, and the compression spring 13 is compressed along the guiding column. The guiding column has a guiding function. The clamping block 14 can slide inside the sliding groove 12 under the push of the compression spring 13, which also facilitates the disassembly of the turntable 16.
[0058] On the basis of the above various specific embodiments, the end cover of the protective shell 11 extends beyond the side wall of the protective shell 11, and the wire 15 is wound between the end cover and the bottom surface of the turntable 16.
[0059] In a specific embodiment, the diameter of the end cover of the protective shell 11 is larger than the diameter of the side wall of the protective shell 11. The end cover of the protective shell 11 extends beyond the side wall of the protective shell 11. A groove is formed between the end cover and the bottom surface of the turntable 16. The wire passing hole on the side wall of the protective shell 11 is provided at the bottom surface of the groove. The wire 15 comes out from the wire passing hole and is directly wound in the groove between the end cover and the bottom surface of the turntable 16. The end cover has a limiting effect on the wire 15 to prevent the wire 15 from coming off the protective shell 11 when being wound.
[0060] On the basis of each of the above specific embodiments, an anti-slip groove 12 is provided on the outer wall of the turntable 16. When the turntable 16 is manually rotated, the frictional force is relatively large and it is not easy to slip.
[0061] The upper end opening of the turntable 16 is connected with a transparent plate 18. The transparent plate 18 can block the inside of the turntable 16 to protect the wire. Through the transparent plate 18, problems such as whether the wire 15 is smoothly wound around the protective shell 11 and whether it is knotted can be observed. When it is found that there is a problem with the winding of the wire 15, it can be discovered and corrected in time to prevent the wire 15 from being damaged or broken.
