Technical Field

[0001] The utility model relates to the field of medical devices, and in particular to an electrical stimulation therapeutic device. Background Art

[0002] Dry eye is an eye disease caused by multiple factors, characterized by tear film imbalance and eye discomfort. Tear film instability, increased tear osmotic pressure, ocular surface inflammation and damage, and neurological abnormalities are the main pathogenesis of dry eye and are also common causes of dry eye.

[0003] Electrical stimulation therapy is one of the commonly used devices for treating dry eyes, which stimulates nerves (for example, by stimulating afferent neurons in the nasal cavity or the trigeminal nerve outside the nose) through electrodes to enhance tear production.

[0004] However, existing electrical stimulation therapeutic devices often cannot adapt to different nose shapes, resulting in the electrodes being unable to fit closely to the user's nose skin, resulting in a poor treatment experience. Utility Model Content

[0005] The embodiment of the utility model provides an electrical stimulation therapeutic apparatus, which can simultaneously meet the requirements of adapting to different nose shapes and ensuring that the electrode is in good contact with the nose skin.

[0028] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The technical solution of the present utility model is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0029] refer to Figures 1 to 5 The electrical stimulation therapeutic apparatus of one embodiment of the utility model comprises a housing 100, an adjustment mechanism 200, a nose clip assembly 300 and an electrode assembly 400. The adjustment mechanism 200 is accommodated in the housing 100 and is rotatably connected to the housing 100. The nose clip assembly 300 is accommodated in the housing 100 and is connected to the adjustment mechanism 200. The electrode assembly 400 comprises an electrode 410 disposed on the nose clip assembly 300, and the electrode 410 is used to fit the skin of the nose to apply a pulse microcurrent. During use, the user can rotate the adjustment mechanism 200 relative to the housing 100, whereby the nose clip assembly 300 connected to the adjustment mechanism 200 also rotates with the adjustment mechanism 200 to approach the bridge of the nose, so that the electrode 410 fits the skin of the nose.

[0030] The electrical stimulation therapeutic device of the present invention can rotatably connect the adjustment mechanism 200 with the housing 100, so that the nose clip assembly 300 connected to the adjustment mechanism 200 can adapt to different nose shapes (such as a relatively straight nose bridge or a relatively flat nose bridge) according to different rotation angles of the adjustment mechanism 200. Therefore, the electrode 410 set on the nose clip assembly 300 can better fit the nose skin, and the treatment effect and experience are better. In addition, the electrical stimulation therapeutic device of the present invention adopts non-invasive stimulation of the skin surface. Specifically, the pulse microcurrent emitted by the electrode 410 is conducted to the anterior ethmoid nerve through the outer skin of the nose, and then through the nasociliary nerve, trigeminal nerve, etc., and finally activates the tear function unit, promotes tear secretion, relieves dry eye symptoms, and can effectively avoid the phenomenon of stimulating the nasal cavity to produce sneezing and other reactions, which causes the treatment electrode 410 to fall off.

[0031] refer to Figures 6 to 8 In this embodiment, the adjustment mechanism 200 includes a first connecting rod 210 and a second connecting rod 220. The first connecting rod 210 is rotatably connected to the housing 100, the second connecting rod 220 is rotatably connected to the first connecting rod 210, and the nose clip assembly 300 is connected to the second connecting rod 220. The first connecting rod 210 and the second connecting rod 220 can be made of a material with high hardness, good processing performance, and good biocompatibility, such as polyoxymethylene (POM).

[0032] Therefore, if Figure 6 As shown, the user can first rotate the first connecting rod 210 to roughly adjust the nose clip assembly 300 to a position suitable for different nose shapes, and then further rotate the second connecting rod 220 to fine-tune the position of the nose clip assembly 300 so that the electrodes 410 on the nose clip assembly 300 fit the nose skin more closely.

[0033] Specifically, the first connecting rod 210 includes a first connecting end 211 and a second connecting end 212 opposite to each other, wherein the first connecting end 211 is used for rotationally connecting to the housing 100 , and the second connecting end 212 is used for rotationally connecting to the second connecting rod 220 .

[0034] In this embodiment, the first connecting end 211 has a U-shaped groove, and the inner wall of the housing 100 is provided with a connecting column 101 ( Figure 3 The connecting column 101 is received in the U-shaped groove of the first connecting end 211, and the first connecting end 211 and the connecting column 101 are rotatably connected through a connecting member (such as a pin / shaft), thereby rotatably connecting the first connecting rod 210 and the housing 100. Of course, this is only shown as an example, and in other embodiments, the first connecting rod 210 can also be rotatably connected to the housing 100 using other structures / methods.

[0035] In order to limit the rotation angle of the first connecting rod 210 within a certain range, preferably, a convex column 102 ( Figure 3 Correspondingly, a limiting groove 213 is provided on one side of the first connecting rod 210 facing the boss 102 ( Figure 7 The first connecting rod 210 is configured to receive the boss 102. Thus, when the first connecting rod 210 rotates to receive the boss 102 in the limiting groove 213, the first connecting rod 210 is abutted by the boss 102 and will not continue to rotate. Preferably, the limiting groove 213 is arranged near the second connecting end 212 of the first connecting rod 210. In this embodiment, the second connecting end 212 of the first connecting rod 210 is configured as a connecting column.

[0036] The second connecting rod 220 includes a third connecting end 221 for connecting to the second connecting end 212, and a free end 222 axially opposite to the third connecting end 221. In this embodiment, the third connecting end 221 of the second connecting rod 220 has a U-shaped groove, and the second connecting end 212 of the first connecting rod 210 is received in the U-shaped groove of the third connecting end 221 and the second connecting end 212 and the third connecting end 221 are rotatably connected through a connecting member (such as a pin / shaft), thereby rotatably connecting the first connecting rod 210 and the second connecting rod 220. Of course, this is only shown as an example, and in other embodiments, the first connecting rod 210 and the second connecting rod 220 can also be rotatably connected using other structures / methods.

[0037] Preferably, the adjustment mechanism 200 further comprises a blocking member 230 disposed at the free end 222 of the second connecting rod 220, and the nose clip assembly 300 is disposed between the third connecting end 221 of the second connecting rod 220 and the blocking member 230 to prevent the nose clip assembly 300 from falling off. Optionally, the blocking member 230 may be made of a material with high hardness, good processing performance, and good biocompatibility, such as polyoxymethylene (POM).

[0038] Specifically, in this embodiment, the blocking member 230 includes a latch 231 and a cap 232 vertically connected to the latch 231. The free end 222 of the second connecting rod 220 is recessed to form a socket (not shown), and the latch 231 of the blocking member 230 is inserted into the socket of the second connecting rod 220 to connect with the second connecting rod 220, and the cap 232 of the blocking member 230 is used to block the nose clip assembly 300. Of course, in other embodiments, the blocking member 230 may also adopt other structures / configurations.

[0039] Preferably, the nose clip assembly 300 is rotatably connected to the second connecting rod 220 to improve the flexibility of the nose clip assembly 300. Thus, the nose clip 310 can not only adjust the position by rotating the first connecting rod 210 and the second connecting rod 220, but also rotate itself to adjust the position, so that the electrodes 410 on the nose clip assembly 300 can fit closely to the nose skin of different nose shapes (for example, larger or smaller nose wings).

[0040] In this embodiment, the nose clip assembly 300 includes two nose clips 310 rotatably connected to the second connecting rod 220, the two nose clips 310 are used to be attached to both sides of the nose, and each nose clip 310 is provided with the electrode 410. Optionally, the nose clip 310 can be made of a material with high hardness, good processing performance, and good biocompatibility, such as polyoxymethylene (POM).

[0041] Specifically, the nose clip 310 includes a plate-shaped main body 311 and two arms 312 connected to the two ends of the main body 311. In this embodiment, the arm 312 is configured as a set of rings arranged outside the second connecting rod 220 and rotatably connected to the second connecting rod 220, wherein the rotation direction of the arm 312 is along the circumference of the second connecting rod 220, in other words, the rotation plane of the arm 312 is perpendicular to the rotation plane of the second connecting rod 220 (of course, the rotation plane of the nose clip 310 is also perpendicular to the rotation plane of the second connecting rod 220). In this way, the range of motion of the nose clip 310 can be maximized, and the flexibility is higher, which is conducive to the electrode 410 on the nose clip assembly 300 to fit closely to the nose skin of different nose shapes.

[0042] Preferably, the adjustment mechanism 200 further includes an elastic member 240 sleeved outside the second connecting rod 220. A receiving hole 241 is reserved in the main body 311 of the nose clip 310, and the two ends 242 of the elastic member 240 are respectively inserted into the receiving holes 241 of the corresponding nose clip 310 to drive the two nose clips 310 to rotate toward each other with the second connecting rod 220 as the axis, so that the electrodes 410 provided on the two nose clips 310 can be more closely attached to both sides of the nose. In this embodiment, the elastic member 240 is constructed as a spring, more specifically, it can be a torsion spring, and the material can be stainless steel.

[0043] During assembly, the arms 312 of the two nose clips 310 are aligned first, and the main body of the elastic member 240 is placed between the two arms 312 of one of the nose clips 310. At the same time, the two ends 242 of the elastic member 240 are respectively inserted into the corresponding receiving holes 241 of the two nose clips 310. Then, the second connecting rod 220 is inserted through the arms 312 of the two nose clips 310 and the main body of the elastic member 240. Finally, the blocking member 230 is inserted into the insertion hole of the free end 222 of the second connecting rod 220.

[0044] To facilitate installation of the electrode assembly 400 on the nose clip assembly 300 , in this embodiment, the nose clip 310 further includes a protruding ring 313 protruding from one side of the main body 311 , and the protruding ring 313 encloses a groove 314 for accommodating the electrode assembly 400 .

[0045] Preferably, the convex ring 313 includes a first half ring 315 and a second half ring 316 of split design, wherein the first half ring 315 is fixedly connected to the main body 311, and the second half ring 316 is detachably connected to the main body 311. Therefore, when installing the electrode assembly 400, the second half ring 316 can be removed first, and then the electrode assembly 400 is placed against the first half ring 315, and then the second half ring 316 is connected to the main body 311. This design is conducive to the installation of the electrode assembly 400 and facilitates the tight fit between the electrode assembly 400 and the convex ring 313.

[0046] As an example, a protrusion 317 may be provided on the second half ring 316, and correspondingly, a bayonet 318 may be provided on the main body 311, and the second half ring 316 and the main body 311 may be connected by inserting the protrusion 317 into the bayonet 318. Of course, in other embodiments, the second half ring 316 may also be detachably connected to the main body 311 using other structures.

[0047] Optionally, one or more holes / slots (e.g. Figure 7The wire hole 319A shown passing through the main body 311 and the wire groove 319B opened on the side of the main body 311 away from the protruding ring 313 are used to facilitate the arrangement of wires, such as wires (not shown) used for electrical connection with the electrode assembly 400.

[0048] Reference again Figure 3 Since the electrode 410 of the electrode assembly 400 is often coated with conductive gel, the nose clip 310 may be easily damaged if placed in the nose clip 310 for a long time. Therefore, it is preferred that the electrode assembly 400 also includes a detachable component, and each electrode 410 is equipped with the detachable component so that the electrode 410 can be removed after each use and a new electrode 410 can be used next time to ensure the sterility of the electrode.

[0049] Specifically, the detachable component includes a fixing portion 420 and a detachable portion 430 detachably connected to the fixing portion 420, the fixing portion 420 is fixedly connected to the nose clip 310 (for example, the fixing portion 42 is tightly fitted in the convex ring 313 in the above-mentioned installation method), the electrode 410 is arranged on the outer side of the detachable portion 430, and the inner side of the detachable portion 430 is detachably connected to the fixing portion 420 (for example, connected in a buckling manner). Therefore, the electrode 410 is easy to assemble and disassemble, and the replacement cost is low.

[0050] In one embodiment, the detachable component is configured as a snap structure, the fixing portion 420 can be configured as a snap mother snap, and the detachable portion is configured as a snap son snap, and the mother snap and the son snap can be pressed together or pulled apart to achieve rapid installation or removal of the electrode.

[0051] Also refer to Figures 1 to 4 In this embodiment, the housing 100 includes a first half shell 110 and a second half shell 120 that are detachably connected. The first half shell 110 is preferably made of a material with high hardness, certain elasticity, and good biocompatibility (such as polycarbonate (PC)) so as to play a supporting role and facilitate shaping (the aforementioned connecting column 101 and the protruding column 102 are therefore preferably arranged on the first half shell 110). In this embodiment, the first half shell 110 is in a sheet shape, including an arc-shaped main body 111 and a protruding ear 112 protruding from the middle of the arc-shaped main body 111.

[0052] The second half shell 120 includes an inner surface 121 and two side surfaces 122 respectively connected to the two sides of the inner surface 121. The inner surface 121 and the two side surfaces 122 together enclose a receiving cavity 123 with a U-shaped cross section, and the first half shell 110 covers the opening of the receiving cavity 123 to enclose together with the second half shell 120 to form a sealed cavity for receiving components (such as the control circuit board 510, the battery 520, etc.) of the electrical stimulation therapeutic device.

[0053] Preferably, the second half shell 120 adopts a segmented design, including a middle portion 124 and two side portions 125 respectively connected to both sides of the middle portion 124 , wherein the middle portion 124 includes a connecting portion 126 and a pocket-shaped portion 127 connected to the connecting portion 126 .

[0054] The side portion 125 is used to fit the two sides of the user's head, and is preferably made of a material with high hardness, no or low elasticity, and good biocompatibility (such as acrylonitrile-butadiene-styrene copolymer (ABS)) to play a supporting role and facilitate shaping.

[0055] Optionally, in order to conveniently fix the electrical stimulation therapeutic device on the user's head, a buckle 103 can be provided on each of the two side portions 125 for fixing the straps. When in use, the user can put the electrical stimulation therapeutic device on the head and tie the straps on both sides behind the head, so that the electrical stimulation therapeutic device can remain stable during use and is easy to use.

[0056] The connecting portion 126 is used to fit the user's forehead, and is preferably made of a material with relatively soft hardness, high elasticity, and good biocompatibility (such as polyurethane (PU)) so as to adapt to different head circumference sizes. The two side portions 125 are respectively connected to the two sides of the connecting portion 126, and the two side portions 125 and the connecting portion 126 together form an arc-shaped structure, corresponding to the arc-shaped main body 111 of the first half shell 110. Since the connecting portion 126 and the side portions 125 of the electrical stimulation therapeutic device of this embodiment are used to fit the user's head, they will not block the line of sight and are easy to use.

[0057] The pocket-shaped portion 127 corresponds to the lug 112 of the first half shell 110, and is preferably made of a material with relatively soft hardness, high elasticity, high insulation strength, and good biocompatibility (such as silicone), so as to facilitate the activity adjustment of the adaptive nose clip assembly 300 and to be in close contact with the nose skin without causing allergies or discomfort. Corresponding to the convex rings 313 of the two nose clips 310, the pocket-shaped portion 127 is provided with two through holes 128 (see Figure 3 ) for installing the electrode 410.

[0058] like Figure 4 As shown, in order to better shape the middle part 124 of the second half shell 120, preferably, the shell 100 also includes a support frame 130, and the support frame 130 is supported on the inner periphery of the middle part 124, so as to maintain the shape of the middle part 124, and the shell 100 will not be severely deformed when adjusting the nose clip assembly 300.

[0059] Specifically, the support frame 130 includes a first section 131 that is substantially straight, a second section 132 that is substantially U-shaped or inverted Ω-shaped and conforms to the ergonomic shape of the forehead and the bridge of the nose, and two first connecting blocks 133 that are respectively used to connect the corresponding ends of the first section 131 and the second section 132. A plurality of first recessed portions 134 and a plurality of first protrusions 135 are provided on the first section 131 and the second section 132. A plurality of protrusions 136 are provided on the first connecting block 133.

[0060] Correspondingly, a plurality of second protrusions 113 are provided on the inner periphery of the first half shell 110, and a portion of the second protrusions 113 correspond to the plurality of first recesses 134 of the support frame 130. A plurality of second recesses 129 are provided on the inner periphery of the second half shell 120, and a portion of the second recesses 129 correspond to the plurality of first protrusions 135 of the support frame 130.

The second recessed portions 129 on the first half shell 120 and the second protrusions 113 on the first half shell can cooperate with each other to achieve the limited fixation of the supporting skeleton 130 in multiple directions, and the multiple second recessed portions 129 on the side portion 125 of the second half shell 120 can be correspondingly engaged with the corresponding second protrusions 113 on the first half shell 110, so as to achieve the mutual connection between the first half shell 110, the supporting skeleton 130, and the second half shell 120.

[0062] Figure 5 FIG. 1 shows a state diagram after the support frame 130 is connected to the second half shell 120 (the first half shell 110 is not shown). Figure 5 As shown, the control circuit board 510 is received in the receiving cavity 123 of the second half shell 120, and can be fixedly installed in the second half shell 120 by means of screws, studs and other components. The main functions of the control circuit board 510 are to monitor the contact impedance between the electrode 410 and the skin, control the pulse current output, etc., so as to monitor in real time to ensure the stability of the output pulse current. In addition, the control circuit board 510 is also connected to the battery 520 ( Figure 3 and Figure 4As can be seen, the electrical stimulation therapeutic device of this embodiment does not need an external power supply when in use. Optionally, the control circuit board 510 is also electrically connected to a USB interface 530 for repeated charging and use.
