Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a nursing aid for children after enterostomy. Background Technology

[0002] Enterostomy is an important treatment for children with congenital megacolon, anal atresia, or other digestive tract malformations or severe abdominal trauma. It involves pulling a segment of the intestine through the abdominal wall to create an opening for excretion instead of through the anus. Postoperative care is crucial for the child's recovery, requiring specialized assistive devices to collect waste, protect the skin around the stoma, and prevent complications to ensure the child can engage in normal daily life and recovery activities.

[0003] Existing stoma care devices mainly include ostomy bags, stoma base plates (or flanges), and auxiliary fixation straps. Structurally, the stoma base plate typically uses hydrocolloid dressings, which adhere directly to the skin around the stoma using their chemical adhesiveness, serving as the base for connecting the ostomy bag. To enhance the stability, some products use an elastic abdominal binder. The binder is generally designed as a single wide elastic band that wraps around the patient's waist and tightens using Velcro or buckles, utilizing the elastic contraction of the fabric to press the base plate towards the abdomen. For two-piece stoma products, the ostomy bag and base plate are often connected using simple plastic snap fasteners or adhesive, achieving a physical connection and seal through interference fit or bonding force.

[0004] However, existing assistive devices have significant limitations in practical applications for children, particularly in terms of stability and complication prevention. Children are naturally active, have weaker body control, and their abdominal muscles are not fully developed. Relying solely on adhesive bases and single-belt fixation structures is insufficient to accommodate children's running, jumping, and rolling movements, making the device prone to displacement, twisting, or even detachment. More seriously, existing abdominal binder structures mostly provide planar compression and lack specialized support structures for the weak area around the stoma root. When a child experiences a sudden increase in intra-abdominal pressure due to crying, coughing, or strenuous exercise, existing devices cannot create effective and uniform counter-pressure around the stoma to offset the impact, causing abdominal contents to easily protrude through the abdominal wall defect, leading to parastomal hernia. This not only increases the child's suffering and the risk of reoperation but also presents significant challenges to postoperative care. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a nursing aid for children after enterostomy surgery. It solves the problems of existing pediatric stoma devices, which have a single fixation method, are difficult to adapt to the active nature of children, and are prone to displacement and dislodgement. Furthermore, due to the lack of targeted support for the stoma root, the device cannot effectively counteract the abdominal pressure impact generated by crying or movement, causing abdominal contents to protrude outwards and leading to parastomal hernia, increasing the difficulty of care and the child's suffering.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nursing aid for children after enterostomy, comprising an abdominal binder, wherein the abdominal binder has symmetrical shoulder straps on its outer side, and symmetrical connecting straps are provided on the outer wall of the abdominal binder away from the shoulder straps. A leg strap is provided through the outer wall of the connecting strap. The abdominal binder, connecting straps and leg straps are all connected by a first Velcro fastener.

A positioning ring is fixedly connected to the inner side of the stoma seat near the opening of the connecting tube. An annular airbag is disposed between the stoma seat and the positioning ring. A pipe that penetrates the abdominal binder is fixedly connected to the outer wall of the annular airbag. A one-way valve is fixedly connected to one end of the pipe.

[0010] Preferably, an extension plug is rotatably connected inside the external threaded cylinder, and a second knob is fixedly connected to the upper surface of the extension plug, with the inner wall of the second knob threadedly connected to the outer wall of the external threaded cylinder.

[0011] Preferably, the clamping mechanism includes a fixing ring, the inner wall of which is fixedly connected to the outer wall of the connecting pipe near the extension pipe. A rectangular limiting groove is formed through one side of the inside of the fixing ring. A rotating disk is rotatably connected inside the fixing ring. A plurality of arc-shaped limiting grooves are formed through the inside of the rotating disk. A connecting rod is slidably connected inside the fixing ring. The outer wall of the connecting rod is slidably connected to the inner walls of the rectangular limiting groove and the arc-shaped limiting groove. A clamping plate is fixedly connected to the outer wall of the connecting rod. A reset assembly is installed on the outer wall of the rotating disk.

[0012] Preferably, the reset assembly includes a first connecting block, one side of the outer wall of the first connecting block is fixedly connected to one side of the outer wall of the rotating disk, an arc-shaped rod is fixedly connected to one side of the outer wall of the first connecting block, a second connecting block is provided through the outer wall of the arc-shaped rod, one side of the outer wall of the second connecting block is fixedly connected to one side of the inner wall of the fixing ring, and a spring is provided through the outer wall of the arc-shaped rod.

[0013] Preferably, one end of the spring abuts against one side of the outer wall of the first connecting block, and the other end of the spring abuts against one side of the outer wall of the second connecting block.

[0014] Preferably, a limiting block is fixedly connected to the outer wall of the connecting rod, and the outer wall of the limiting block is used to abut against the side of the rectangular limiting groove inside the fixing ring to limit the movement of the connecting rod.

[0015] Preferably, a button rod is fixedly connected to the outer wall of the rotating disk, and the outer wall of the button rod is slidably connected to the inside of a fixed ring, wherein a groove is provided inside the fixed ring for the button rod to slide.

[0016] Preferably, the outer wall of the rack plate is slidably connected to the inside of the connecting pipe, and the inside of the connecting pipe is provided with a groove for the rack plate to slide. The length of the inner sleeve is greater than the length of the rack plate, which is used to prevent liquid from entering the groove for the rack plate to slide.

[0017] This invention provides a nursing aid for children after enterostomy. It has the following beneficial effects:

[0018] 1. This invention significantly improves the safety and stability of postoperative care by setting up a comprehensive wearable fixation structure and anti-hernia components. The shoulder straps, connecting straps, and leg straps, in conjunction with the abdominal binder, form a multi-point positioning system, effectively preventing displacement or dislodgement of the stoma aids due to the child's active nature. Specifically, the anti-hernia mechanism utilizes the expansion force generated by the inflation of the ring-shaped airbag, which, under the constraint of the stoma seat and positioning ring, can closely conform to the skin around the stoma, providing continuous and uniform flexible pressure. This pressure effectively supports the weak area of ​​the abdominal wall and resists abdominal pressure impact, thereby greatly reducing the risk of complications such as parastomal hernia after pediatric enterostomy without affecting the stoma's drainage function, and alleviating the child's suffering.

[0019] 2. This invention features a linked cleaning mechanism that enables stoma and tubing cleaning without disassembly, greatly simplifying the nursing process. Rotating the first knob drives the internal threaded cylinder to rotate. On one hand, the threaded transmission causes the external threaded cylinder and the protruding nozzle to move downwards and extend into the tubing. On the other hand, the meshing of gears and a rack and pinion simultaneously drives the inner sleeve to slide laterally. This linked mechanism ensures that during cleaning, the inner sleeve automatically avoids obstruction, allowing the protruding nozzle to pass through the cross-shaped opening valve for flushing. In the non-cleaning state, the cross-shaped opening valve returns to its original position and closes to prevent backflow. This design avoids the infection risks associated with frequent stoma baseboard replacements or tubing disassembly, maintaining a hygienic environment around the stoma.

[0020] 3. This invention solves the problem of loose connections and easy leakage of ostomy bags by setting up a precise mechanical clamping mechanism. The arc-shaped limiting groove on the rotating disk and the rectangular limiting groove on the fixing ring cooperate to convert the rotational motion of the rotating disk into the radial linear motion of the connecting rod and the clamping plate. When it is necessary to fix the ostomy bag, the clamping plate retracts inward, forming a multi-locking structure with the wedges on the extension tube, firmly pressing the neck of the ostomy bag. Combined with the spring structure in the reset assembly, the clamping mechanism has a self-locking or automatic reset function, making operation simple and the clamping force constant, effectively preventing excrement leakage and soiling of clothing, and improving the quality of life of the child.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a nursing aid for children after enterostomy, including an abdominal binder 1, which is used to wrap and fix the child's waist. Symmetrical shoulder straps 2 are provided on the outer side of the abdominal binder 1 to prevent the aid from slipping down. Symmetrical connecting straps 3 are provided on the outer wall of the abdominal binder 1 away from the shoulder straps 2, for connecting lower limb fixation components. A leg strap 4 is provided through the outer wall of the connecting strap 3 to secure the leg straps at the groin for improved stability. First Velcro 5 is provided at the connection points of the abdominal binder 1, connecting straps 3, and leg strap 4 for easy adjustment of tightness and quick on / off. A connecting tube 6 is provided inside the abdominal binder 1. As a drainage channel for stoma excrement, the outer wall of the connecting tube 6 is fixedly connected to the mounting cloth 7, which provides the connection medium between the connecting tube 6 and the abdominal binder 1. The outer wall of the mounting cloth 7 is provided with a second Velcro 8 for connecting the mounting cloth 7 near the abdominal binder 1. The second Velcro 8 enables the detachable installation of the connecting tube 6. One end of the connecting tube 6 is equipped with an anti-hernia mechanism, which is used to apply pressure to the stoma periphery to prevent parastomal hernia. The outer wall of the connecting tube 6 is fixedly connected to a connecting seat 14, which is used to support the cleaning component. A cleaning mechanism is installed inside the connecting seat 14, which is used to rinse and clean the inside of the device. The other end of the connecting tube 6 is equipped with a clamping mechanism, which is used to clamp and fix the stoma bag.

[0032] The cleaning mechanism includes an internally threaded cylinder 15, which serves as a rotary drive component. The outer wall of the internally threaded cylinder 15 is rotatably connected to the inner wall of the connecting seat 14, allowing it to rotate only in its original position. A gear 16 is fixedly connected to the lower end of the internally threaded cylinder 15, transmitting rotational power. A first knob 17 is fixedly connected to the upper end of the internally threaded cylinder 15, allowing the operator to manually rotate and input power. An externally threaded cylinder 18 is threadedly connected inside the internally threaded cylinder 15, converting the rotational motion into vertical lifting motion. A nozzle 19 is fixedly connected to the lower end of the externally threaded cylinder 18, dispensing cleaning fluid. The nozzle 19 has multiple through holes 20 inside, which are used to spray water in all directions. The connecting pipe 6 has an inner sleeve 21 that is slidably connected inside. The inner sleeve 21 is used for cleaning and sealing. A rack plate 22 that meshes with the gear 16 is fixedly connected to one side of the upper surface of the inner sleeve 21. The rack plate 22 converts the rotation of the gear 16 into linear movement of the inner sleeve 21. A cross-shaped opening valve 23 is fixedly connected inside the inner sleeve 21. The cross-shaped opening valve 23 uses elastic closure to block odors and excrement. The cross-shaped opening valve 23 is located on the lower side of the nozzle 19 so that the valve can be opened when the nozzle 19 moves down.

[0033] Specifically, by rotating the first knob 17, the inner threaded cylinder 15 is rotated, which in turn drives the outer threaded cylinder 18 to move the protrusion 19 downward using the threaded transmission. At the same time, the gear 16 drives the rack plate 22 to move, causing the inner sleeve 21 to slide. When the protrusion 19 moves down and opens the cross-shaped opening valve 23, the cleaning fluid is sprayed out through the through hole 20, which realizes convenient cleaning of the inside of the connecting tube and the stoma without disassembling the ostomy bag, maintaining hygiene and reducing the risk of infection.

[0034] Please see the appendix Figure 1 - Appendix Figure 8 An extension tube 38 is fixedly connected to the other end of the connecting tube 6 to increase the extension length of the pipe for easier connection. Multiple wedges 39 are fixedly connected to the outer wall of the extension tube 38 to increase frictional resistance and prevent the pipe from slipping. The anti-hernia mechanism includes a stoma seat 9, which is located on the outer wall of the connecting tube 6 near the installation cloth 7 as the basic support structure of the anti-hernia component. A positioning ring 10 is fixedly connected to the inner side of the stoma seat 9 near the opening of the connecting tube 6 to limit the pipe and maintain its centering. An annular airbag 11 is provided between the stoma seat 9 and the positioning ring 10 to fill the gap and provide flexible buffering. A pipe 12 that runs through the abdominal band 1 is fixedly connected to the outer wall of the annular airbag 11 as a gas delivery channel. A one-way valve 13 is fixedly connected to one end of the pipe 12 to control the gas in and out and lock the pressure inside the airbag.

[0035] Specifically, the physical barbs of the wedge 39 ensure the stability of the connecting tube, while the one-way valve 13 inflates the annular airbag 11 through the pipe 12, causing the airbag to expand within the stoma seat 9 and compress the positioning ring 10 and the surrounding area, thereby applying uniform pressure to the tissues around the stoma. This pressure can effectively seal the gap and counteract abdominal pressure to prevent the abdominal tissues from protruding outward, achieving a comprehensive effect of preventing parastomal hernia and enhancing the sealing of the device.

[0036] Please see the appendix Figure 1 - Appendix Figure 8 An extension plug 24 is rotatably connected inside the external threaded cylinder 18 to achieve the sealing of the movement inside the cylinder. A second knob 25 is fixedly connected to the upper surface of the extension plug 24 as the operating end for applying rotational torque. The inner wall of the second knob 25 is threadedly connected to the outer wall of the external threaded cylinder 18, and the position is locked by thread engagement.

[0037] Specifically, by rotating the second knob 25, the internal extension plug 24 can be moved axially or locked by utilizing its threaded connection with the external threaded cylinder 18, thereby enabling convenient opening and closing of the device opening and sealing adjustment, ensuring a stable connection and preventing accidental loosening.

[0038] Please see the appendix Figure 1 - Appendix Figure 8 The clamping mechanism includes a fixed ring 26, which serves as the mounting base for the mechanism. The inner wall of the fixed ring 26 is fixedly connected to the outer wall of the connecting pipe 6 near the extension pipe 38, determining the clamping position and maintaining relative stillness. A rectangular limiting groove 27 is formed through one side of the fixed ring 26 to restrict the radial linear movement of the moving part. A rotating disk 28 is rotatably connected inside the fixed ring 26 to provide rotational driving force. Multiple arc-shaped limiting grooves 29 are formed through the rotating disk 28, using the change of groove trajectory to drive the displacement of the part. A connecting rod 30 is slidably connected inside the fixed ring 26 to transmit displacement as a transmission component. The outer wall of the connecting rod 30 is slidably connected to the inner walls of the rectangular limiting groove 27 and the arc-shaped limiting grooves 29, and the rotation is controlled by the groove fit. Rotational motion is converted into radial linear motion. A clamping plate 31 is fixedly connected to the outer wall of the connecting rod 30, directly contacting and clamping the target object. A reset assembly is installed on the outer wall of the rotating disk 28. The reset assembly includes a first connecting block 34, one side of which is fixedly connected to the outer wall of the rotating disk 28, serving as a force application fulcrum for the rotating part. An arc-shaped rod 35 is fixedly connected to the outer wall of the first connecting block 34, bearing the elastic element and guiding it. A second connecting block 36 is provided through the outer wall of the arc-shaped rod 35, one side of which is fixedly connected to the inner wall of the fixing ring 26, serving as a blocking fulcrum for the fixed part. A spring 37 is provided through the outer wall of the arc-shaped rod 35, storing energy through deformation to provide a reverse thrust.

[0039] Specifically, by rotating the rotating disk 28, the interlacing guiding effect of the arc-shaped limiting groove 29 and the rectangular limiting groove 27 forces the connecting rod 30 to drive the clamping plate 31 to converge towards the center, thereby achieving stable clamping of the connected object; at the same time, the rotation process drives the first connecting block 34 to compress the spring 37. When the external force is removed, the spring 37 releases its elastic potential energy to push the rotating disk 28 to rotate in the opposite direction, causing the clamping plate 31 to automatically release and reset.

[0040] Please see the appendix Figure 1 - Appendix Figure 8 One end of the spring 37 abuts against one side of the outer wall of the first connecting block 34 and undergoes compression deformation as the first connecting block 34 moves. The other end of the spring 37 abuts against one side of the outer wall of the second connecting block 36, providing a fulcrum for reaction force to form elastic potential energy. The outer wall of the connecting rod 30 is fixedly connected to the limiting block 32, which increases the force-bearing area and serves as a stroke stop. The outer wall of the limiting block 32 is used to abut against the side of the fixed ring 26 near the rectangular limiting groove 27 to prevent the connecting rod 30 from leaving the track or excessive displacement, and to limit the movement of the connecting rod 30.

[0041] Specifically, the spring 37 abuts against the first connecting block 34 and the second connecting block 36, creating an elastic reset mechanism to ensure that the mechanism can quickly rebound after the external force disappears. In conjunction with the abutting action of the limiting block 32 and the fixing ring 26, the maximum stroke of the connecting rod 30 is set, effectively preventing parts from falling off and structural damage caused by excessive opening or movement, and ensuring the stability and safety of the device in long-term use.

[0042] Please see the appendix Figure 1 - Appendix Figure 8 A button lever 33 is fixedly connected to the outer wall of the rotating disk 28, allowing the user to apply rotational torque by flicking it. The outer wall of the button lever 33 is slidably connected to the inside of the fixing ring 26. The fixing ring 26 has a groove inside for the button lever 33 to slide, limiting the rotation angle range of the rotating disk and serving as a guide. The outer wall of the rack plate 22 is slidably connected to the inside of the connecting pipe 6. The connecting pipe 6 has a groove inside for the rack plate 22 to slide, providing a guide path for linear movement to maintain smooth motion. The inner sleeve 21 is longer than the rack plate 22, preventing liquid from entering the groove inside for the rack plate 22 to slide, thus providing physical isolation to avoid dirt from jamming the sliding components.

[0043] Specifically, by sliding the button lever 33 within the groove of the fixed ring 26, precise control and limiting of the rotation of the rotating disk 28 are achieved. At the same time, the extended portion of the inner sleeve 21 covers the sliding groove, effectively isolating the liquid flowing inside the pipe from the precision sliding components, ensuring the cleanliness of the transmission structure and the reliability of operation during the adjustment process.

[0044] Working principle: When using this device, first align the center hole of the stoma seat 9 with the stoma location on the child's abdominal wall, adjust the position of the installation cloth 7 and the abdominal binder 1, and initially fix them with the second Velcro 8. Then, wrap the abdominal binder 1 around the waist, cross the left and right shoulder straps 2 over the shoulders, and wrap the connecting strap 3 and leg straps 4 around the groin. Adjust the length and fasten them with the first Velcro 5 at each point to form a stable multi-point support system and prevent the device from shifting due to the child's movements. After wearing, inflate the annular airbag 11 through the tube 12. The gas is locked inside the airbag by the one-way valve 13. The inflated annular airbag 11 is restricted by the stoma seat 9 and the positioning ring 10 to expand only inward and to the side of the body, thus gently and tightly compressing the abdominal wall around the stoma, preventing parastomal hernia.

[0045] When collecting excrement, the open end of the disposable ostomy bag is placed over the outer wall of the extension tube 38. The operator then activates button 33, causing the rotating disk 28 to rotate within the fixing ring 26. As the rotating disk 28 rotates, its arc-shaped limiting groove 29 exerts a radial thrust on the connecting rod 30 inserted within it. Because the rectangular limiting groove 27 on the fixing ring 26 restricts the connecting rod 30 to move only in a straight line, the connecting rod 30 causes the clamping plate 31 to contract towards the central axis of the connecting tube 6, tightly pressing the ostomy bag against the wedge 39 on the extension tube 38 and its outer wall. The wedge 39 embeds into the ostomy bag material, increasing friction and ensuring the connection seal remains intact. During this process, the spring 37 is compressed and stores energy. When disassembly is required, button 33 is released or reversed. Under the restoring force of the spring 37, the rotating disk 28 reverses and resets, and the clamping plate 31 is released.

[0046] Daily excrement flows unidirectionally into the ostomy bag through the inner sleeve 21 within the connecting tube 6 and the normally closed cross-shaped valve 23, which prevents reflux. When cleaning and maintaining the stoma and the inside of the tubes is required, the device does not need to be removed. First, unscrew the second knob 25 to remove the extension plug 24, and inject warm water or cleaning fluid from above. Then, rotate the first knob 17, causing the internal threaded cylinder 15 to rotate. The rotation of the internal threaded cylinder 15 drives the rack plate 22 via the gear 16 at the bottom, which in turn causes the inner sleeve 21 connected to the rack plate 22 to slide downwards or avoid obstacles inside the connecting tube 6, causing the cross-shaped valve 23 to move downwards or open. Simultaneously, the threads inside the internal threaded cylinder 15 drive the external threaded cylinder 18 to extend downwards, causing the nozzle 19 to move downwards and pass through or approach the valve position. The through-hole 20 on the nozzle 19 sprays the cleaning fluid in a jet pattern, rinsing the stoma surface and the inner wall of the connecting tube 6, with the wastewater flowing into the ostomy bag below. After cleaning, rotate the first knob 17 in the opposite direction to reset all parts, and then tighten the extension plug 24 again.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
