Description

Technical Field

[0001] This invention specifically relates to a defecation assistance device after gastrointestinal surgery. Background Technology

[0002] Post-operative patients, especially those who have undergone abdominal surgery, often experience slowed gastrointestinal motility due to reduced physical activity, the use of painkillers or antiemetics, or surgical trauma, leading to constipation. Constipation can be relieved by eating easily digestible foods, performing abdominal exercises, and taking medication. Additionally, tapping the sacrum and coccyx during defecation can stimulate the intestines and aid in bowel movements.

[0003] For example, Chinese invention patent application number 202010334680.6 provides a gastrointestinal nursing device for assisting intestinal peristalsis massage. This device can effectively assist patients in defecation or gas relief by massaging with a massage balloon, promote gastrointestinal motility, and effectively relieve constipation symptoms.

[0004] However, most traditional assistive devices can only assist in defecation by massaging the stomach and intestines. This method has a weak defecation assistance effect and cannot automatically tap the sacrum and coccyx during defecation to significantly improve defecation smoothness. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a postoperative defecation assistance device for gastrointestinal surgery, which solves the problem mentioned in the background art that most traditional assistance devices can only assist defecation through gastrointestinal massage, resulting in a weak defecation assistance effect and failing to achieve the technical problem of automatically tapping the sacrum and coccyx during defecation to significantly improve defecation patency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a postoperative defecation assistance device for gastrointestinal surgery, comprising:

[0007] The support frame is provided with legs at the bottom and two sets of support plates are provided on the support frame;

[0008] The mounting shell is fixedly mounted on the support frame, and a through groove is provided on the mounting shell;

[0009] A striking block is slidably disposed within the through groove along the through direction of the groove, and a striking pad is provided on one side of the striking block; and

[0010] A drive mechanism is disposed within the mounting housing and connected to the striking block to drive the striking block to reciprocate and strike the sacrum and coccyx.

[0011] In a preferred embodiment, the drive mechanism includes:

[0012] An inclined rail is provided on the striking block, with one end located inside the mounting housing;

[0013] A baffle is disposed inside the mounting housing to block its opening, and an elastic element is disposed between the baffle and the striking block;

[0014] A drive wheel is rotatably mounted within the mounting housing along its axis. A drive column is provided on the axle side of the drive wheel. During rotation of the drive wheel, the drive column is driven to move into the inclined rail.

[0015] A power unit is disposed within the mounting housing and connected to the drive wheel to control the rotation of the drive wheel.

[0016] In a preferred embodiment, the power assembly includes:

[0017] The first synchronous pulley is mounted on the drive wheel and coaxially connected to it;

[0018] A second synchronous pulley, rotatably disposed within the mounting housing along its axis, is connected to the first synchronous pulley via a synchronous belt; and

[0019] A first motor is fixedly installed inside the mounting housing, and the output shaft of the first motor is coaxially connected to the second synchronous pulley.

[0020] In a preferred embodiment, the striking block is provided with a positioning ring, and the mounting shell is provided with a positioning post, with the positioning ring slidably sleeved on the positioning post.

[0021] In a preferred embodiment, one end of the inclined rail is rotatably connected to the striking block, and the striking block is provided with an adjustment component to adjust the inclination of the inclined rail.

[0022] In a preferred embodiment, the adjustment component includes:

[0023] A worm gear is disposed at the hinge point between the inclined rail and the striking block;

[0024] A connecting shaft is rotatably mounted on the striking block along its axis, with one end exposed outside the striking block and connected to an adjusting wheel; and

[0025] A worm gear is located at one end of the connecting shaft and meshes with the worm wheel.

[0026] In a preferred embodiment, the striking block has a mounting hole, and the striking pad has a flexible mounting post, which passes through the mounting hole and is interference-fitted with it.

[0027] In a preferred embodiment, one end of each of the two sets of support plates is hinged to the support frame. The bottom of the support frame is provided with a mounting frame, and a lifting mechanism is provided inside the mounting frame. The lifting mechanism is connected to the two sets of support frames to drive the two sets of support frames to rotate and lift simultaneously along their hinge points with the support frame.

[0028] In a preferred embodiment, the lifting mechanism includes:

[0029] A bidirectional lead screw is rotatably mounted within the mounting frame along its axis, and a second motor for driving the bidirectional lead screw to rotate is provided within the mounting frame;

[0030] The sliding frame is provided in two sets, and is respectively sleeved on both ends of the bidirectional lead screw and screwed to it. The sliding frame can slide along the axis of the bidirectional lead screw within the mounting frame.

[0031] The first connecting rod is provided in two sets. One end of each set of the first connecting rod is hinged to the two sets of sliding frames, and the other end of the first connecting rod is provided with a hinged push rod. The push rod is slidably mounted on the support frame along its axis.

[0032] The second connecting rod is provided in two sets. One end of the second connecting rod is hinged to the push rod, and the other end is hinged to the support plate.

[0033] In a preferred embodiment, a protective pad is provided on the support plate to cover the hinge gap between the support plate and the support frame, and a waist support is provided on one side of the mounting shell.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. When in use, this device is placed directly above the toilet. The patient can sit on the support frame and support board to defecate. When defecation is difficult, the driving mechanism controls the percussion block to move back and forth in the channel, which in turn drives the percussion pad to move back and forth, percussing the patient's sacrum and coccyx. This stimulates the intestines, enhances the urge to defecate, improves the smoothness of defecation, and achieves the purpose of assisting defecation. Moreover, compared with traditional massage, the method of percussing the sacrum and coccyx is more effective in enhancing the urge to defecate, and it does not require manual operation, making it highly practical.

[0036] 2. This device allows the patting pad to be disassembled. Rotating the adjusting wheel drives the worm gear, which, in conjunction with the worm wheel, rotates the inclined rail along its hinge point with the patting block, thus adjusting the rail's inclination. The power assembly controls the drive wheel's rotation, causing the drive column on the drive wheel to move into the inclined rail. Through its engagement with the inclined surface of the rail, the patting block slides and retracts along the through-slot. When the drive column disengages from the inclined rail, the elastic element causes the patting block to spring out and pat the patient's sacrum and coccyx. The greater the inclination of the inclined rail, the greater the amplitude of the patting block's movement, resulting in a stronger patting force, adapting to different patient groups.

[0037] 3. When in use, the device can also control the second motor to start and drive the bidirectional lead screw to rotate. During the rotation of the bidirectional lead screw, the two sets of sliding frames move along the axis of the bidirectional lead screw, thereby driving the push rod to slide on the support frame through the first connecting rod. During the sliding process, the push rod can push the support plate to rotate and lift along its hinge point with the support frame through the second connecting rod, thereby lifting the patient's legs, thereby widening the anorectal angle, and making the patient's body lean forward through the lumbar support, making defecation smoother.

[0051] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0052] Example:

[0053] like Figure 1 As shown, the present invention provides a defecation assistance device after gastrointestinal surgery, including a support frame 101, a support leg 102 at the bottom of the support frame 101, and two sets of support plates 107 on the support frame 101. In use, the device can be placed on the toilet or bedpan and supported by the support leg 102. The patient can sit on the support frame 101 and the two sets of support plates 107 to defecate.

[0054] like Figure 1 , 2As shown in Figure 3, in this embodiment, a mounting shell 104 is fixedly installed on the support frame 101. A through groove 106 is provided on the mounting shell 104. A slapping block 201 is slidably engaged in the through groove 106 along its through direction. A slapping pad 206 is provided on one side of the slapping block 201. A driving mechanism connected to the slapping block 201 is provided in the mounting shell 104. The driving mechanism drives the slapping block 201 to reciprocate and slap the sacrum and coccyx. The driving mechanism includes a sloping rail 301 mounted on the striking block 201. One end of the sloping rail 301 is located inside the mounting housing 104. A baffle 208 is provided inside the mounting housing 104 to block the opening of the mounting housing 104. An elastic element 203 is provided between the baffle 208 and the striking block 201. A drive wheel 401 that can rotate along its axis is provided inside the mounting housing 104. A drive column 403 is provided on the axial side of the drive wheel 401. During the rotation of the drive wheel 401, the drive column 403 is driven to move into the sloping rail 301.

[0055] The drive wheel 401 can be rotated to drive multiple drive columns 403. During movement, the drive columns 403 enter the inclined rail 301 through an opening at one end, and the inclined surface of the rail 301 drives the striking block 201 to retract into the mounting housing 104, simultaneously compressing the elastic element 203. A positioning ring 202 is provided on the striking block 201, and a positioning post 207 is provided inside the mounting housing 104. The positioning ring 202 slides on the positioning post 207, and the cooperation between the positioning post 207 and the positioning ring 202 positions the striking block 201, preventing it from shifting during movement. The drive wheel 401 continues to rotate until the drive column 403 disengages from the inclined rail 301. The inclined rail 301 loses the force applied by the drive column 403 and pops outward under the restoring ability of the elastic element 203, thus continuously striking the patient's sacrum and coccyx to assist in defecation.

[0056] like Figure 3 , 4 As shown in Figure 5, in this embodiment, the mounting housing 104 is provided with a power assembly connected to the drive wheel 401, which controls the rotation of the drive wheel 401. The power assembly includes a first synchronous pulley 402 disposed on and coaxially connected to the drive wheel 401, and a second synchronous pulley 405 rotatable along its axis disposed inside the mounting housing 104. The second synchronous pulley 405 is connected to the first synchronous pulley 402 via a synchronous belt 404. A first motor 406 is fixedly disposed inside the mounting housing 104, and the output shaft of the first motor 406 is coaxially connected to the second synchronous pulley 405.

[0057] By controlling the first motor 406 to start and drive the second synchronous pulley 405 to rotate, the second synchronous pulley 405 drives the drive wheel 401 to rotate through the cooperation of the first synchronous pulley 402 and the synchronous belt 404, thereby realizing the automatic control of the drive wheel 401 without the need for manual control of the drive wheel 401 to rotate, which improves the convenience of using the device.

[0058] like Figure 4 , 5 As shown, in this embodiment, one end of the inclined rail 301 is rotatably connected to the striking block 201. The striking block 201 is provided with an adjustment component, which adjusts the inclination of the inclined rail 301. The adjustment component includes a worm gear 302 disposed at the hinge point between the inclined rail 301 and the striking block 201. The striking block 201 is provided with a rotatable connecting shaft 303. One end of the connecting shaft 303 is exposed outside the striking block 201 and connected to an adjusting wheel 305. The other end of the connecting shaft 303 is provided with a worm 304 that meshes with the worm gear 302.

[0059] The worm gear 304 can be rotated by rotating the adjusting wheel 305. During the rotation, the worm gear 304 drives the inclined rail 301 to rotate along its hinge point with the worm wheel 302 through meshing, and its position is self-locked. This adjusts the inclination of the inclined rail 301 relative to the striking block 201. The greater the inclination of the inclined rail 301 relative to the striking block 201, the greater the movement distance of the striking block 201 when the drive column 403 rotates, resulting in a greater rebound force of the striking block 201. This allows for adjustment of the striking force to suit patients with different force requirements, thus improving the applicability of the device.

[0060] like Figure 5 As shown, in this embodiment, the tapping block 201 has a mounting hole 204, and the tapping pad 206 is provided with a flexible mounting post 205. The mounting post 205 passes through the mounting hole 204 and is interference-fitted with it. The tapping pad 206 can be pulled out to disengage the mounting post 205 from the mounting hole 204, making it easy to disassemble the tapping pad 206 and rotate the adjusting wheel 305. It can also be used to replace the contaminated tapping pad 206 to prevent cross-contamination.

[0061] like Figure 2 , 3 As shown in Figure 6, in this embodiment, one end of each of the two sets of support plates 107 is hinged to the support frame 101. The bottom of the support frame 101 is provided with a mounting frame 103, and a lifting mechanism is provided inside the mounting frame 103. The lifting mechanism is connected to the two sets of support frames 101 to drive the two sets of support frames 101 to rotate and lift simultaneously along their hinge points with the support frame 101.

[0062] The lifting mechanism includes a bidirectional lead screw 501 rotatably mounted in a mounting frame 103 along its axis. A second motor 503 is installed in the mounting frame 103 to drive the bidirectional lead screw 501 to rotate. Both ends of the bidirectional lead screw 501 are fitted with threaded sliding frames 502. The sliding frames 502 can slide along the axis of the bidirectional lead screw 501 within the mounting frame 103. One end of each set of sliding frames 502 is provided with a hinged first connecting rod 504. The other end of the first connecting rod 504 is provided with a hinged push rod 505. The push rod 505 is slidably mounted on the support frame 101 along its axis. One end of the push rod 505 is hinged to a second connecting rod 506. One end of the second connecting rod 506 is hinged to the support plate 107.

[0063] In use, the device can also be activated by controlling the second motor 503 to drive the bidirectional lead screw 501 to rotate. During the rotation of the bidirectional lead screw 501, the two sets of sliding frames 502 move along the axis of the bidirectional lead screw 501, thereby driving the push rod 505 to slide on the support frame 101 through the first connecting rod 504. During the sliding process, the push rod 505 can push the support plate 107 to rotate and lift along its hinge point with the support frame 101 through the second connecting rod 506, thereby lifting the patient's legs and widening the anorectal angle. Furthermore, a protective pad 108 is provided on the support plate 107 to cover the hinge gap between the support plate 107 and the support frame 101, preventing the support plate 107 from pinching the patient during movement. A lumbar support 105 is provided on one side of the mounting shell 104, which makes the patient's body lean forward, making defecation smoother.

[0064] Specific usage and beneficial effects of the present invention:

[0065] When in use, the device is placed directly above the toilet. The patient can sit on the support frame 101 and support plate 107 to defecate. When defecation is difficult, the tapping block 201 can be controlled to move back and forth in the channel 106, which in turn drives the tapping pad 206 to move back and forth, tapping the patient's sacrum and coccyx. This stimulates the intestines, enhances the urge to defecate, and improves the smoothness of defecation, thus assisting in defecation. Moreover, compared with traditional massage, tapping the sacrum and coccyx is more effective in enhancing the urge to defecate, and it does not require manual operation, making it highly practical.

[0066] The device allows the slapping pad 206 to be disassembled. Rotating the adjusting wheel 305 drives the worm gear 304 to rotate. During rotation, the worm gear 304, in conjunction with the worm wheel 302, drives the inclined rail 301 to rotate along its hinge point with the slapping block 201, thus adjusting the inclination of the inclined rail 301. The first motor 406 drives the second synchronous pulley 405 to rotate. During rotation, the second synchronous pulley 405, through the interaction of the first synchronous pulley 402 and the synchronous belt 404, controls the rotation of the drive wheel 401, driving... During the rotation of wheel 401, drive column 403 on drive wheel 401 moves into inclined rail 301. Through the cooperation with the inclined surface of inclined rail 301, it drives the patting block 201 to slide and retract along the through groove 106. When drive column 403 disengages from inclined rail 301, under the action of elastic element 203, patting block 201 pops out to pat the patient's sacrum and coccyx. The greater the inclination of inclined rail 301, the greater the range of motion of patting block 201, thus making the patting force greater to adapt to different people.

[0067] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
