Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, and more specifically, to an anorectal muscle electrical stimulation training device. Background Technology

[0002] Spinal cord injury is the most serious complication of spinal cord injury, often leading to severe functional impairment of the limbs below the injured segment. Spinal cord injury not only causes serious physical and psychological harm to the patient, but also imposes a huge economic burden on the whole society. Spinal cord injury patients are at risk of decreased anal sphincter strength, which can easily lead to constipation. Stimulation training of the anus and rectum is needed to reduce constipation and help facilitate defecation in the future.

[0003] Generally, before performing anorectal stimulation training, prepare warm water, a soft towel or tissue, and a lubricant such as petroleum jelly. The patient should lie on their side and relax. Clean the anal area with warm water and apply lubricant around the anus. Medical staff can wear silicone gloves and apply lubricant to their fingers. Slowly insert the fingers into the rectum and gently stimulate in a clockwise direction, being gentle and avoiding excessive force. During stimulation, make circular motions along the intestinal wall with the fingers for 15-20 seconds to stimulate the intestines. Repeat the above steps 3 times, with an interval of 1-2 minutes between each session. In other words, medical staff need to use their fingers to perform rotational stimulation training on the rectal wall of patients with spinal cord injuries to help them complete defecation. However, this can easily lead to finger fatigue and bacterial infection for medical staff.

[0004] Therefore, it is necessary to propose an anorectal muscle electrical stimulation training device to solve the problems existing in the prior art. Summary of the Invention

[0010] According to an embodiment of the present invention, an anorectal muscle electrical stimulation training device is provided with a shielding module on the front end tube. The shielding module includes a first shielding tube, a second shielding tube, and a third shielding tube. The inner wall of the first shielding tube is provided with a plurality of guide grooves, and the front end tube is provided with guide strips corresponding to the guide grooves. The third shielding tube is disposed on the first shielding tube, and the second shielding tube is movably disposed between the first shielding tube and the third shielding tube. The third shielding tube is movably provided with a plurality of fan-shaped shielding plates, and the plurality of fan-shaped shielding plates are movably connected to the second shielding tube. A release film layer is disposed on the fan-shaped shielding plates.

[0011] According to an embodiment of the present invention, an anorectal muscle electrical stimulation training device is provided with an inner guide coil movably disposed on a second shielding tube, an inner guide strip corresponding to the inner guide coil is disposed on the inner wall of a third shielding tube, a plurality of hollow guide strip holes are disposed on the outer wall of the third shielding tube, an outer protrusion corresponding to the hollow guide strip hole is disposed on the inner guide coil, a linkage ring is disposed on the plurality of outer protrusions, a top frame is movably disposed on the outer protrusions, a plurality of uprights are also disposed on the third shielding tube, and the uprights pass through the top frame, and a fan-shaped shielding plate is movably connected to the top frame and the uprights respectively.

[0012] According to an embodiment of the present invention, the anorectal muscle electrical stimulation training device further includes an internal drive mechanism inside the third shielding tube. The internal drive mechanism includes an internal drive ring, a first spring, and a first sliding ring. The internal drive ring, the first sliding ring, and the first spring are all disposed on the first shielding tube. The first spring abuts against the inner end of the third shielding tube and the first sliding ring, respectively.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] This invention provides an anorectal muscle electrical stimulation training device. The device includes a main body comprising a handle and a stimulation rod. The stimulation rod is mounted on the front end of the handle, and two electrode pads are mounted on both sides of its end. When medical personnel use the device, the stimulation rod is slowly inserted into the anus and rectum of a spinal cord injury patient. Firstly, the electrical stimulation transmitter is activated, causing the electrode pads on the stimulation rod to stimulate the anus and rectum, stimulating the nerves in the lower rectum and inducing a defecation response. Secondly, an arc-shaped ball end is also provided at the end of the stimulation rod. Because the arc-shaped ball end protrudes relative to the electrode pads, when not performing electrical stimulation training on the anus and rectum of a spinal cord injury patient, medical personnel can rotate the handle to stimulate the training rod, causing the arc-shaped ball end to rotate within the anus and rectum, also stimulating the nerves in the lower rectum and inducing a defecation response.

[0018] The main body of the electrical stimulation training device with this structure replaces the fingers of medical staff for rectal stimulation training, reducing the fatigue of medical staff, reducing bacterial infection, and improving the efficiency of stimulation. Moreover, different stimulation modes can be used according to different patients, which also improves the patient's comfort and makes it easier for the patient to complete defecation.

[0019] The anorectal muscle electrical stimulation training device of the present invention, other advantages, objectives and features of the present invention will be apparent in part from the following description, and in part will be understood by those skilled in the art through study and practice of the invention.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] like Figure 1As shown, the present invention provides an anorectal muscle electrical stimulation training device, comprising: an electrical stimulation training device body 100, the electrical stimulation training device body 100 including a handle body 1 and a stimulation training rod 2. Here, the stimulation training rod 2 is installed at the front end of the handle body 1, and two electrode plates 20 are installed on both sides of the end of the stimulation training rod 2. For the convenience of medical personnel, the stimulation training rod 2 has a wire (not shown) inside, and an electrical connection hole (not shown) is provided on the stimulation training rod 2. The stimulation training rod 2 is connected to the electrical connection hole through the wire. When in use, the stimulation training rod 2 is connected to the electrical stimulation transmitter (not shown) through the electrical connection hole. Therefore, when medical personnel use the electrical stimulation training device body 100, the stimulation training rod 2 is slowly inserted into the anorectal region of a spinal cord injury patient. On the one hand, the electrical stimulation transmitter is activated, thereby causing the electrode plates 20 on the stimulation training rod 2 to stimulate the anorectal region, stimulating the nerves at the lower end of the patient's rectum, causing the patient to produce a defecation response. On the other hand, an arc-shaped ball end 21 is also provided at the end of the stimulation training rod 2. Since the arc-shaped ball end 21 protrudes relative to the electrode plate 20, when the anus and rectum of the spinal cord injury patient is not subjected to electrical stimulation training, medical staff can rotate the handle body 1 to stimulate the training rod 2 and drive the arc-shaped ball end 21 to rotate in the anus and rectum of the spinal cord injury patient. This can also stimulate the nerves at the lower end of the rectum of the patient, causing the patient to produce a defecation response.

[0034] The main body 100 of this electrical stimulation training device replaces the fingers of medical staff for rectal stimulation training, reducing the fatigue of medical staff, reducing bacterial infection, and improving the efficiency of stimulation. Moreover, different stimulation modes can be used according to different patients, which also improves the patient's comfort and makes it easier for the patient to complete defecation.

[0035] like Figure 2 As shown, in some embodiments of the present invention, an inner rotating rod 12 is installed in the front tube 11 of the handle body 1. Correspondingly, an inner fixing hole 21 corresponding to the inner rotating rod 12 is opened at the rear end of the stimulation training rod 2. A side block 13 is provided on the inner rotating rod 12, and a side groove 22 corresponding to the side block 13 is also provided on one side of the inner fixing hole 21. Therefore, the above-mentioned stimulation training rod 2 can be installed on the handle body 1 through the inner fixing hole 21 and the inner rotating rod 12. After use, a new stimulation training rod 2 can be replaced to perform rectal stimulation training on other patients with the same spinal cord injury, which greatly improves the medical safety effect and avoids cross-infection.

[0036] Exemplary drive mechanism

[0037] like Figure 3As shown, in some embodiments of the present invention, a drive mechanism 14 is installed inside the handle body 1. Here, the drive mechanism 14 is connected to the inner rotating rod 12. A switch button 10 corresponding to the drive mechanism 14 is installed on the outer wall of the handle body 1. Therefore, the drive mechanism 14 can be activated by the switch button 10. The drive mechanism 14 then drives the inner rotating rod 12 to rotate through the rod sleeve 121. Consequently, the stimulation training rod 2 installed on the inner rotating rod 12 also rotates synchronously, thereby replacing the manual rotation of the handle body 1 by medical staff, thereby reducing the fatigue of medical staff and improving the efficiency of rectal stimulation training.

[0038] Furthermore, the drive mechanism 14 of the above structure includes a drive motor 15, a reduction module 16, a control board 17, and a battery body 18. The drive motor 15, reduction module 16, control board 17, and battery body 18 are installed inside the handle body 1. The reduction module 16 is located in front of the drive motor 15, while the control board 17 and battery body 18 are located behind the drive motor 15, greatly improving the utilization of the internal space of the handle body 1. The drive motor 15 is rotatably connected to the inner rotating rod 12 via the reduction module 16, and the control board 17... The control board 17 is electrically connected to the battery body 18, the drive motor 15, and the switch button 10, respectively. When the medical staff activates the switch button 10, the drive motor 15 is activated by the control board 17. The drive motor 15 then starts and drives the deceleration module 16 to rotate. The deceleration module 16 reduces the rotation of the drive motor 15 to a set speed. The inner rotating rod 12 then drives the stimulation training rod 2 to rotate at the set speed. The rod rotates at this speed for 15-20 seconds to stimulate and train the intestines. The above three times are repeated with an interval of 1-2 minutes each time, which makes it easier for the patient to defecate.

[0039] Exemplary occlusion module

[0040] like Figures 4-10 As shown, furthermore, during the finger-rectal stimulation training operation, attention needs to be paid to any resistance and reflexive contraction of the patient's sphincter; gently rotate the finger to observe whether there is stool expulsion or gas accumulation in the intestine. That is to say, even medical staff using the main body 100 of the electrical stimulation training device need to pay attention to the above precautions. However, when the patient exhales gas during the above operation, it will be directly expelled onto the medical staff's hands, which will inevitably cause discomfort to the medical staff. Therefore, it is necessary to improve the above phenomenon. In some embodiments of the present invention, a shielding module 3 is installed on the front end tube 11 to shield the medical staff's hands and prevent the patient from expelling gas onto the medical staff's hands.

[0041] Specifically, the shielding module 3 of this structure includes a first shielding tube 31, a second shielding tube 32, and a third shielding tube 33. The inner wall of the first shielding tube 31 is provided with a plurality of guide grooves 311. Correspondingly, a guide strip 111 corresponding to the guide grooves 311 is installed on the front end tube 11. The first shielding tube 31 is conveniently installed on the front end tube 11 through the guide strip 111 and the guide grooves 311.

[0042] The third shielding tube 33 is installed on the first shielding tube 31, and the second shielding tube 32 is movably installed between the first shielding tube 31 and the third shielding tube 33. Multiple fan-shaped shielding plates 34 are movably installed on the third shielding tube 33, and the multiple fan-shaped shielding plates 34 are movably connected to the second shielding tube 32. The second shielding tube 32 can support the multiple fan-shaped shielding plates 34, so that the fan-shaped shielding plates 34 are perpendicular to the third shielding tube 33. The multiple fan-shaped shielding plates 34 form a shielding disc, which can shield the hands of medical staff. Since a release film layer (not shown) is installed on the fan-shaped shielding plates 34, the outermost layer of the release film can be peeled off after use, making it convenient for subsequent patient use.

[0043] After use, the fan-shaped shield 34 can be pushed forward by the second shield tube 32, so that the fan-shaped shield 34 rotates forward and is no longer perpendicular to the third shield tube 33. This makes it easier for medical staff to place the main body 100 of the electrical stimulation training device on the table and prevents the main body 100 of the electrical stimulation training device from rotating. This increases the stability of the main body 100 of the electrical stimulation training device on the table and prevents it from falling to the ground and being damaged.

[0044] Exemplary second shielding tube

[0045] like Figures 5-8 As shown, in some embodiments of the present invention, an inner guide ring 321 is movably installed on the second shielding tube 32. Specifically, the inner guide ring 321 slides on the second shielding tube 32. Correspondingly, an inner guide strip 331 corresponding to the inner guide ring 321 is installed on the inner wall of the third shielding tube 33. A plurality of hollow guide strip holes 332 are opened on the outer wall of the third shielding tube 33. The inner guide ring 321 has an outer protrusion 322 corresponding to the hollow guide strip hole 332. A linkage ring 320 is arranged on the plurality of outer protrusions 322. The linkage ring 320 can drive the plurality of outer protrusions 322 to move. Therefore, through the structure of the outer protrusions 322, the inner guide strip 331, etc., the second shielding tube 32 can reciprocate inside the third shielding tube 33.

[0046] Furthermore, a top frame 323 is movably mounted on the outer protrusion 322, and the top frame 323 can rotate on the outer protrusion 322. Multiple columns 332 are also mounted on the third shielding tube 33, and the columns 332 pass through the top frame 323 and are movably connected to the fan-shaped shielding plate 34. Simultaneously, the fan-shaped shielding plate 34 is also movably connected to the columns 332. Since the columns 332 are fixed to the outer wall of the third shielding tube 33, they provide support. The front and rear ends of the top frame 323 are connected to the fan-shaped shielding plate 34 and the outer protrusion 322, thus providing movable support. The third shielding tube 33 contains... When the second shielding tube 32 moves, it drives the outer protrusion 322 to move along the hollow guide strip hole 332. Then, the top frame 323 drives the fan-shaped shielding plate 34 to rotate relative to the column 332, so that the second shielding tube 32 supports the fan-shaped shielding plate 34. The fan-shaped shielding plate 34 is rotated from being perpendicular to the third shielding tube 33 to no longer being perpendicular. In this way, after the fan-shaped shielding plate 34 contacts the table, it changes from the original point contact to line contact. This prevents the main body 100 of the electrical stimulation training device from rotating after being placed on the table, increases the stability of the main body 100 of the electrical stimulation training device on the table, and prevents it from falling to the ground and being damaged.

[0047] Exemplary internal drive mechanism

[0048] Furthermore, in some embodiments of the present invention, an internal drive mechanism 35 is also installed inside the third shielding tube 33. Here, the internal drive mechanism 35 includes an internal drive ring 351, a first spring 352, and a first sliding ring 353. The internal drive ring 351, the first sliding ring 353, and the first spring 352 are all installed on the first shielding tube 31. The first spring 352 abuts against the inner end of the third shielding tube 33 and the first sliding ring 353, respectively. In this way, the first sliding ring 353 abuts against the internal drive ring 351, so that the internal drive ring 351 is movably connected to the inner guide ring 321. In addition, the first spring 352 also plays an internal support role for the second shielding tube 32, preventing the second shielding tube 32 from moving and affecting the support of the fan-shaped shielding plate 34.

[0049] The aforementioned inner drive ring 351 can drive the inner guide ring 321 to move. Simultaneously, the inner drive ring 351 can also rotate in the opposite direction. Multiple drive notches 355 are formed on the inner drive ring 351, and multiple driven protrusions 325 are mounted on the second blocking tube 32. The driven protrusions 325 are slidably connected to the drive notches 355. Therefore, when the second blocking tube 32 rotates, the driven protrusions 325 on the second blocking tube 32 can abut against the drive notches 355 of the inner drive ring 351, causing the inner drive ring 351 to rotate. 1. Move towards the interior of the third blocking tube 33, so that the driving notch 355 of the inner drive ring 351 moves to the back of the inner guide bar 331. The inner guide bar 331 can then slide along the driving notch 355, causing the inner drive ring 351 to rotate. This causes the end of the inner guide bar 331 to abut against the bottom of the driving notch 355, thus fixing the inner guide bar 331 in place. In other words, the second blocking tube 32 is held in place by the first spring 352 in a compressed state, preventing the second blocking tube 32 from shifting and affecting the support of the fan-shaped blocking plate 34.

[0050] Furthermore, the inner guide ring 321 has multiple first guide notches 324, and the inner drive ring 351 has second guide notches 354 corresponding to the first guide notches 324. The inner guide strip 331 passes through the first guide notches 324, and the inner guide strip 331 can enter the second guide notches 354 or move out from them. The end of the inner guide strip 331 has a pointed tip, so when the inner guide strip 331 is at the bottom of the drive notch 355, the fan-shaped shielding plate 34 is perpendicular to the third shielding tube 33. Multiple fan-shaped shielding plates 34 form a shielding disc, which can shield the hands of medical staff.

[0051] When the second shielding tube 32 rotates again and drives the inner drive ring 351 to move into the third shielding tube 33, the inner guide strip 331 moves from the bottom of the drive notch 355 to the top of the drive notch 355, and can then move into the second guide notch 354. At this time, under the action of the first spring 352, it pushes against the inner guide ring 321, driving multiple outer protrusions 322 to move along the hollow guide strip hole 332. Then the top frame 323 drives the fan-shaped shielding plate 34 to rotate relative to the column 332, realizing the support of the fan-shaped shielding plate 34 by the second shielding tube 32. It rotates from being perpendicular to the third shielding tube 33 to no longer being perpendicular. In this way, after the fan-shaped shielding plate 34 contacts the table, it changes from the original point contact to line contact, preventing the main body 100 of the electrical stimulation training device from rotating after being placed on the table. This increases the stability of the main body 100 of the electrical stimulation training device on the table and prevents it from falling to the ground and being damaged.

[0052] Furthermore, in some embodiments of the present invention, a second sliding ring 326 and a second spring 327 are installed at the front end of the second shielding tube 32, and a third sliding ring 333 is also installed on the inner wall of the third shielding tube 33. The third sliding ring 333 is connected to multiple inner guide strips 331, which increases the structural strength of the third shielding tube 33. The second spring 327 is installed between the second sliding ring 326 and the third sliding ring 333. Here, the second spring 327 is a tension spring, which provides the second shielding tube 32 with a spring force to move into the third shielding tube 33. The spring force of the first spring 352 prevents the second shielding tube 32 from moving and increases the internal stability.

[0053] Exemplary limiting mechanism

[0054] like Figure 9 As shown, further, in some embodiments of the present invention, a limiting mechanism 36 is installed on the front end of the third blocking tube 33. Here, the limiting mechanism 36 cooperates with the column 332 to fix the fan-shaped blocking plate 34 more securely and prevent the fan-shaped blocking plate 34 from rotating. The limiting mechanism 36 of the above structure includes a first limiting ring 361, a second limiting ring 362, and a limiting spring 363. Specifically, the first limiting ring 361 is fixedly installed on the front end of the third blocking tube 33, while the second limiting ring 362 is movably installed on the front end of the third blocking tube 33. The limiting spring 363 is installed between the first limiting ring 361 and the second limiting ring 362. The limiting spring 363 is used to provide circumferential elastic support for the second limiting ring 362.

[0055] Furthermore, multiple limiting notches 364 are provided on the first limiting ring 361, and a limiting slider 365 is slidably installed in the limiting notches 364. Correspondingly, an arc-shaped slot 366 is provided on the second limiting ring 362, and a limiting rod 367 corresponding to the arc-shaped slot 366 is installed on the limiting slider 365. Therefore, by rotating the second limiting ring 362, the limiting rod 367 moves along the arc-shaped slot 366, thus realizing the movement of the limiting slider 365 from the limiting notch 364 inward. This means that the limiting slider 365 no longer blocks the fan-shaped blocking plate 34, and then the fan-shaped blocking plate 34 can rotate.

[0056] It is understandable that there are side limiting blocks on both sides of the limiting slider 365 and a limiting guide groove in the limiting notch 364. The side limiting blocks slide in the limiting guide groove, so that the limiting slider 365 will not disengage when it moves in the limiting notch 364.

[0057] Exemplary external fixation mechanism

[0058] like Figure 10As shown, in some embodiments of the present invention, an inner fixing head 312 is further installed on the first blocking tube 31, and correspondingly, an outer fixing mechanism 37 is installed on the front end tube 11. The inner fixing head 312 is connected to the outer fixing mechanism 37, which facilitates the installation of the blocking module 3 on the front end tube 11 of the handle body 1, and its subsequent removal from the handle body 1.

[0059] Specifically, the external fixing mechanism 37 of this structure includes an external pull head 371, an inner tube 372, and a third spring 373. The external pull head 371 is movably mounted on the outer wall of the front end tube 11, while the inner tube 372 is fixedly mounted on the outer wall of the front end tube 11. The inner fixing head 312 is detachably connected to the inner tube 372, while the external pull head 371 and the inner tube 372 are slidably connected. The third spring 373 is mounted on the outer wall of the front end tube 11 and abuts against the external pull head 371 and the inner tube 372. Since the third spring 373 is a tension spring, it provides tension to the external pull head 371, allowing the external pull head 371 to move the inner tube 372. This allows the inner tube 372 to fix the inner fixing head 312, thereby enabling the installation of the shielding module 3 on the front end tube 11.

[0060] Furthermore, multiple pressure balls 374 are installed on the outer wall of the inner tube 372. Correspondingly, a track 313 corresponding to the pressure balls 374 is formed on the outer wall of the inner fixed head 312. A first ball groove 375 and a second ball groove 376 are formed on the inner wall of the outer pull head 371. Here, the first ball groove 375 is located on one side of the second ball groove 376, and the depth of the first ball groove 375 is greater than the depth of the second ball groove 376. When the shielding module 3 is installed on the front end tube 11, the outer pull head 371 is pulled backward first, so that the pressure balls 374 on the outer wall of the inner tube 372 are... The first ball groove 375 is located in the first ball groove 375. Then, the inner fixing head 312 is placed into the inner tube 372, and the two pressure balls 374 can easily enter the corresponding track 313. Then, the outer pull head 371 is released. Under the pulling force of the third spring 373, the outer pull head 371 moves to the front end on the outer wall of the inner tube 372. The pressure balls 374 are in the second ball groove 376. In this way, the second ball groove 376 exerts a squeezing effect on the pressure balls 374, so that the pressure balls 374 are fixed in the track 313, thus realizing the fixing effect of the first blocking tube 31.

[0061] Then, by pulling the external head 371 backward on the outer wall of the inner tube 372, the pressure ball 374 can enter the first ball groove 375 from the second ball groove 376. Then, the inner fixing head 312 is pulled out from the inner tube 372, so that the shielding module 3 can be easily removed from the handle body 1.
