Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a portable vagus nerve stimulator. Background Technology

[0002] As a neuromodulation device, vagus nerve stimulators typically require adaptation to different types of electrodes, such as gel electrodes and metal electrodes, to achieve differentiated clinical treatment effects. However, based on existing technology, it has been found that existing nerve stimulators have significant deficiencies in structural design, which seriously affect the ease of use.

[0003] Existing neurostimulators present significant challenges for users when replacing built-in electrodes. Furthermore, the lack of an integrated electrode carrying and replacement solution, coupled with the absence of dedicated storage space for spare and replaced electrodes, hinders portable electrode replacement and makes them prone to shaking, detachment, or even loss during transport or handling, resulting in substantial management loopholes. These issues collectively lead to a poor user experience, low operational efficiency, and, in clinical applications, potential disruptions to treatment continuity and safety due to improper electrode management. Summary of the Invention

[0004] To overcome the shortcomings of existing vagus nerve stimulators, which lack a built-in electrode storage structure and make electrode replacement difficult, this invention provides a convenient vagus nerve stimulator.

[0005] The technical solution is as follows: A portable vagus nerve stimulator includes a body, a top cover, electrode I, and electrode II; the body is provided with a top cover; the body is provided with at least two electrodes I; the body is also provided with at least two electrodes II; it also includes knobs, rings, compression blocks, limiting cylinders, sliding blocks, elastic elements, sleeves, fixing rings, and fastening components; each electrode I has a slot; at least two knobs are rotatably connected to the body; each knob is fixedly connected with a ring; each ring is fixedly connected with at least two compression blocks; at least two limiting cylinders are fixedly connected to the body; at least two sliding blocks are slidably connected to each limiting cylinder, and at least two elastic elements are fixedly connected between each sliding block and the corresponding limiting cylinder; at least two sleeves are fixedly connected to the top cover; at least two fixing rings are fixedly connected to the body; a fastening component is connected to the body, the fastening component being used to fasten the top cover to the body.

[0006] More preferably, it also includes a rubber block; the rubber block is fixedly attached to the limiting cylinder; the rubber block is fixedly attached to the machine body.

[0007] More preferably, the side of the extrusion block away from the ring is set in an arc shape, and the side of the sliding block away from the limiting cylinder is provided with an arc-shaped notch.

[0008] More preferably, the sleeve has at least two through holes.

[0009] More preferably, the inner side of the sleeve is provided with multiple clamping parts.

[0010] More preferably, it also includes collars; at least two collars are fixedly attached to the top cover.

[0011] More preferably, a disinfectant gel is provided on the inside of the collar.

[0012] More preferably, the fastening assembly includes a fixing strip, a rotating shaft, and a crossbar; at least two fixing strips are fixedly connected to the body; a rotating shaft is rotatably connected to each fixing strip; a crossbar is fixedly connected to each rotating shaft, and a groove that mates with the crossbar is opened in the upper cover.

[0013] More preferably, the fixing strip has several grooves.

[0014] More preferably, the top cover is provided with a fixing part, and the fixing part is made of rubber.

[0015] The advantages and positive effects of this invention are: (1) The electrode I is limited by the limiting cylinder, the lower part of the electrode I is supported by the rubber block, and the electrode I is clamped and limited by all the sliding blocks, so that the electrode I remains stable during use and avoids detachment. The extrusion block is locked by the arc notch, thereby locking the knob and preventing accidental contact of the knob, which would cause the extrusion block to fall off the sliding block and cause the electrode I to loosen and fall off.

[0016] (2) After the top cover is fastened to the body, the upper surface of electrode II abuts against the upper inner side of the top cover, and the lower surface of electrode II abuts against the upper surface of the body. That is, the body and the top cover work together to clamp and limit electrode II. The sleeve and the fixing ring work together to limit electrode II, thereby storing electrode II and keeping electrode II stable during storage, preventing electrode II from shaking during the movement of the body.

[0017] (3) By opening a through hole on the sleeve, air can enter the inside of the sleeve, thereby avoiding the problem of difficulty in removing electrode II due to excessive negative pressure inside the sleeve when removing electrode II. The elastic deformation of the clamping part is used to clamp electrode II with different head shapes, achieving more reliable positioning and thus improving the adaptability of the sleeve. The upper part of electrode I is limited by the collar, and the disinfectant gel set inside the collar is used to sterilize electrode I after use.

[0018] (4) By using the sleeve and the body together to store electrode II, electrode II can be stored to avoid the problem of loss of electrode II and without interfering with the normal use of electrode I. The crossbar is inserted into the fixing part of the top cover to limit the top cover, so that the top cover and the body are tightly fastened to prevent the top cover from falling off. This ensures the tightness and reliability of the connection between the body and the body when moving and using, effectively preventing accidental opening. It is simple and quick to use, and effectively improves the safety of the body and the user experience. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0032] Example 1: A portable vagus nerve stimulator, based on Figures 1-9 As shown, it includes an organism 1, a top cover 11, electrode I 2 and electrode II 3; the top cover 11 is provided on the organism 1; two electrodes I 2 are provided on the organism 1; two electrodes II 3 are also provided on the organism 1;

[0033] It also includes a knob 201, a ring 202, a pressing block 203, a limiting cylinder 204, a sliding block 205, an elastic element 2051, a sleeve 206, a fixing ring 207, and a fastening assembly; each electrode I2 has a slot 21; two knobs 201 are rotatably connected to the body 1; a ring 202 is fixedly connected to the lower inner side of each knob 201; four pressing blocks 203 are fixedly connected to each ring 202 at equal intervals; two limiting cylinders 204 are fixedly connected to the body 1; four sliding blocks 205 are slidably connected to each limiting cylinder 204 at equal intervals, and two elastic elements 2051, which are springs, are fixedly connected between each sliding block 205 and the corresponding limiting cylinder 204; two sleeves 206 are fixedly connected to the top inner side of the upper cover 11; two fixing rings 207 are fixedly connected to the upper surface of the body 1; and a fastening assembly is connected to the body 1.

[0034] In a further preferred embodiment of the present invention, such as Figures 5-6 As shown, it also includes a rubber block 2041; the rubber block 2041 is fixedly connected to the lower part of the inner side of the limiting cylinder 204; the rubber block 2041 is fixedly connected to the body 1.

[0035] The side of the extrusion block 203 away from the ring 202 is set in an arc shape, and the side of the sliding block 205 away from the limiting cylinder 204 is provided with an arc-shaped notch 2052, which is used to make the extrusion block 203 fit into the arc-shaped notch 2052.

[0036] The upper part of the sleeve 206 has four through holes 2061 at equal intervals in an annular shape, which are used to allow air to enter the sleeve 206 so that the electrode I2 can be removed.

[0037] The inner side of the sleeve 206 is provided with a multi-layer clamping part 2062, which is used to limit the head of electrode I2.

[0038] In a further preferred embodiment of the present invention, such as Figure 2 As shown, it also includes a collar 208; two collars 208 are fixedly connected to the top inner side of the upper cover 11.

[0039] The inner side of the collar 208 is provided with disinfectant gel for sterilizing electrode I2 after use.

[0040] In some optional implementations of this embodiment, such as Figures 10-11 As shown, the fastening assembly includes a fixing strip 301, a rotating shaft 302, and a crossbar 303; two fixing strips 301 are fixedly connected to the body 1; a rotating shaft 302 is rotatably connected to each fixing strip 301; a crossbar 303 is fixedly connected to each rotating shaft 302, and a groove that mates with the crossbar 303 is opened in the upper cover 11.

[0041] The fixing strip 301 has several grooves to increase the friction when holding the hand.

[0042] The top cover 11 is provided with a fixing part 1101, and the fixing part 1101 is made of rubber.

[0043] In this embodiment, electrodes I2 and II3 are of different types. The initial state of the upper cover 11 is not attached to the body 1. The two electrodes I2 are manually inserted into a limiting cylinder 204 beforehand, thereby limiting the electrodes I2 through the limiting cylinder 204. The lower part of the electrodes I2 is supported by the rubber block 2041. However, the limiting cylinder 204 and the rubber block 2041 alone can easily cause the electrodes I2 to fall off during use, thus affecting the user experience. Then, the knob 201 is manually rotated. The rotation of the knob 201 drives the ring 202 to rotate, which in turn drives all the pressing blocks 203 to rotate. The rotating pressing blocks 203 touch the corresponding sliding blocks 205 and cause pressure on the sliding blocks 205. The compression compresses the elastic element 2051, causing all the sliding blocks 205 to move towards the center of the limiting cylinder 204. This allows all the sliding blocks 205 to engage in the slot 21 at the bottom of electrode I2, thus clamping and limiting electrode I2 and ensuring its stability during use, preventing detachment. Furthermore, the arc-shaped notch 2052 locks the extrusion block 203 into place when it rotates and presses against the sliding block 205, locking the extrusion block 203 and thus locking the knob 201. This prevents accidental activation of the knob 201, which could cause the extrusion block 203 to detach from the sliding block 205, leading to electrode I2 loosening and falling off.

[0044] Next, the two electrodes II3 are inserted into a retaining ring 207 respectively, thereby pre-fixing the electrodes II3 through the retaining ring 207. Then, the upper cover 11 is fastened onto the body 1, as follows. Figure 1 and Figure 2 As shown, simultaneously, the upper cover 11 moves the two sleeves 206, causing the two sleeves 206 to respectively fit over the upper outer side of an electrode II 3, as shown. Figure 2 As shown, the upper part of electrode II3 is limited by sleeve 206, and after the upper cover 11 is fastened to the body 1, the upper inner part of the upper cover 11 will abut against the upper surface of electrode II3, so that the upper surface of electrode II3 abuts against the upper inner part of the upper cover 11, and the lower surface of electrode II3 abuts against the upper surface of the body 1. That is, the body 1 and the upper cover 11 cooperate to clamp and limit electrode II3, and the sleeve 206 and the fixing ring 207 cooperate to limit electrode II3, thereby realizing the storage of electrode II3 and keeping electrode II3 stable during storage, preventing electrode II3 from shaking during the movement of body 1.

[0045] It is important to note that by creating a through hole 2061 in the sleeve 206, air can enter the interior of the sleeve 206, thus avoiding the problem of difficulty in removing electrode II3 due to excessive negative pressure inside the sleeve 206. Furthermore, by providing a barbed clamping part 2062 inside the sleeve 206, when different types of electrode II3 are inserted, the clamping part 2062 can elastically deform, providing effective clamping force and enabling smooth insertion and removal. This utilizes the elastic deformation of the clamping part 2062... The sleeve 206 is designed to hold electrodes II3 with different head shapes, achieving more reliable positioning and improving its adaptability. With the two collars 208, after the two electrodes I2 are used, the top cover 11 will be fastened to the body 1. At this time, the two collars 208 on the body 1 will limit the upper part of one electrode I2, making the electrode I2 more stable on the body 1. The disinfectant gel inside the collars 208 will sterilize the used electrode I2 for the next use.

[0046] When replacing the two electrodes I2, the two electrodes I2 inside the limiting cylinder 204 are replaced with two electrodes II3 to achieve differentiated treatment effects and meet diverse clinical needs. By manually turning the knob 201 in reverse, the knob 201 rotates, driving the ring 202 to rotate, which in turn drives all connected components to rotate, thereby releasing the limiting block 205 on the electrodes I2. Then, the two electrodes I2 are removed from the limiting cylinder 204, and the two electrodes II3 are inserted into their respective limiting cylinders 204. The knob 201 is then turned in the same way as above, so that the sliding block 205 limits the electrodes II3, thus completing the replacement of electrodes I2 and electrodes II3. The replaced electrodes I2 are inserted into a fixing ring 207, and the sleeve 206 and the fixing ring 207 work together to store the replaced electrodes I2, thus storing the electrodes I2 and preventing the problem of losing the electrodes I2.

[0047] When the machine body 1 is in use, the upper cover 11 needs to be pulled off the machine body 1. At this time, the upper cover 11 drives the two sleeves 206 to move, and the two sleeves 206 drive the corresponding electrodes II 3 to move. Then, the upper cover 11 is inverted and placed on the lower part of the machine body 1, as follows. Figure 4 As shown, this allows one end of the two electrodes II3 to abut against the lower surface of the body 1, while the other end of the two electrodes II3 remains within the corresponding sleeve 206, thereby enabling the storage and retrieval of the electrodes II3, avoiding the problem of loss of the electrodes II3, and not interfering with the normal use of the electrodes I2.

[0048] When the machine body 1 is in use, the operator holds the two fixing strips 301 on the side of the machine body 1. The fixing strips 301 have several grooves to increase the friction when the operator holds the machine body 1. The crossbar 303 is initially not fastened to the upper cover 11. When the upper cover 11 is fastened to the upper part of the machine body 1, the operator manually moves the crossbar 303, causing it to rotate around the pivot 302. This causes the crossbar 303 to engage with the fixing part 1101 of the upper cover 11, thus limiting the upper cover 11 and ensuring a tight fit between the upper cover 11 and the machine body 1, preventing the upper cover 11 from being locked in place. The problem of the crossbar 303 detaching from the body 1 is prevented by limiting the crossbar 303 through the fixing part 1101, thus avoiding the problem of the crossbar 303 detaching from the fixing part 1101 due to accidental contact. When the body 1 is in use, the upper cover 11 needs to be placed upside down on the lower part of the body 1. At this time, the crossbar 303 can be rotated again to make the crossbar 303 lock into the fixing part 1101 of the upper cover 11. This ensures the tightness and reliability of the connection between the body 1 during movement and use, effectively preventing accidental opening. It is simple and quick to use, effectively improving the safety of the body 1 and the user experience.
