Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a novel device for the reduction, fixation, and protection of intussusception in children. Background Technology

[0002] Intussusception in children is a common acute abdominal condition in infants under 2 years old. The core pathology involves a segment of intestine telescoping into an adjacent segment, obstructing the passage of intestinal contents. Without timely treatment, it can lead to fatal complications such as intestinal necrosis and septic shock. Clinically, air enema reduction is the preferred treatment for this condition, and the treatment outcome directly depends on the accuracy of the procedure and the child's cooperation. However, traditional reduction techniques face numerous technical challenges due to the physiological characteristics of infants (poor tolerance to medical procedures) and limitations of existing equipment, severely restricting treatment efficiency and safety.

[0003] During traditional reduction procedures, infants and young children are prone to crying and struggling due to discomfort. Family members often lack professional immobilization skills, making it difficult to achieve stable restraint when manually assisting. The child's body shifting directly interferes with the doctor's precise control of the enema angle and pressure. Furthermore, family members struggle to control the restraint force; too light a pressure is insufficient, while too heavy a pressure may cause limb compression injury. Simultaneously, family members' anxiety can disrupt the procedure, further prolonging the time and increasing radiation dose under X-ray fluoroscopy. In addition, rectal tube insertion is a crucial step in air enema reduction. The tube must be precisely inserted into the child's anus and kept stable to ensure effective enema pressure on the intestines. However, traditional operating tables lack lower limb restraint structures, allowing the child's buttocks to shift forward, backward, or sideways during struggle. This not only increases the difficulty of tube insertion and the risk of anal mucosal damage but may also cause the inserted tube to loosen or dislodge, requiring repeated procedures and exacerbating the child's pain.

[0004] It is important to note that air enema reduction must be performed under X-ray fluoroscopy to observe the progress of reduction. Traditionally, the anal canal relies solely on manual support by the doctor or fixation with adhesive tape. On the one hand, infants' skin is delicate, and adhesive tape fixation can easily cause skin allergies or damage; on the other hand, when the child struggles, the anal canal is prone to displacement, changes in depth, or even prolapse, leading to unstable intestinal pressure, pressure fluctuations, and irregular traction on the intestinal wall, increasing the risk of complications such as intestinal mucosal damage and intestinal perforation. Therefore, we have proposed a novel pediatric intussusception reduction and fixation protective device to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel protective device for the reduction and fixation of pediatric intussusception, in order to solve the problems mentioned in the background art regarding the traditional reduction of pediatric intussusception, such as the easy displacement and difficulty in fixing the child's limbs, the increased difficulty of anal canal operation due to unlimited displacement, the easy displacement and dislodgement of the anal canal after fixation, and the increased pain, complications and radiation dose for the child during the reduction of intussusception.

[0006] This utility model provides the following technical solution:

[0007] A novel pediatric intussusception reduction and fixation protective device includes a pediatric intussusception reduction operating table, a limb fixation device for fixing the child's limbs, a protective device for protecting the child during fluoroscopic observation, and an anal canal fixation device for fixing the anal canal. The operating table has an examination pedal near one end of its top. The operating table has a first sliding groove near the top of its two longer sides, and a first inlet is formed in the first sliding groove. Each first sliding groove has a set of guardrails, handrails, and sliding limb fixation seats that are slidably installed. The protective device is located on the two guardrails near one side of the operating table, and the limb fixation device is located on the two limb fixation seats.

[0008] Preferably, the limb fixation device includes a lower limb fixation seat and a support frame for supporting the child's lower leg; the lower limb fixation seat includes a seat body, the bottom of the seat body is fixed to the top of the limb fixation seat, and a first U-shaped mounting groove is provided on the top of the seat body, in which a first rotating shaft is installed;

[0009] The support frame is connected to a first elastic fixing strap near the lower front side, and a calf support plate is connected to the upper side of the support frame near the lower limb fixing seat. A connecting block is connected to the outer wall of the calf support plate away from the support frame. The connecting block is engaged inside the first U-shaped mounting groove and is rotatably connected to the first rotating shaft.

[0010] Preferably, the protective device includes a hollow winding rod and a radiation-proof lead curtain fixedly wound around one side of the outer wall of the hollow winding rod. The hollow winding rod is rotatably sleeved on two handrails on one side of the operating table, and hooks that can be hung on the other handrail are connected to both ends of the handrails.

[0011] Preferably, a crossbar connects the two limb fixation seats, the anal canal fixation device is located on the crossbar, the anal canal fixation device includes a base and a connecting plate rotatably connected to the top of the base, a fixing plate is fixedly connected to the top of the connecting plate, and an anal canal receiving groove adapted to the outer diameter of the anal canal is opened on the top surface of the fixing plate, and the groove depth of the anal canal receiving groove is not less than half of the outer diameter of the anal canal.

[0012] Preferably, an anti-slip silicone ring is attached to the inner wall of the anal canal receiving groove, and the inner wall of the anti-slip silicone ring is provided with anti-slip texture; limiting pressure plates are symmetrically connected to both sides of the anal canal receiving groove, and the limiting pressure plates are elastic metal sheets.

[0013] Preferably, the armrest is connected to a hand fixing strap, which is an elastic webbing with its free end detachably connected via Velcro, and the inner wall of the hand fixing strap is covered with a soft cotton cloth layer.

[0014] This utility model has the following beneficial effects:

[0015] 1. This application provides graded fixation adapted to the physiological characteristics of infants and young children. The limb fixation device, through the cooperation of the lower limb fixation seat and the support frame, can flexibly adjust its position to adapt to the lower limb length of infants and young children of different heights. The calf support plate of the support frame is rotatably connected to the seat body through the first pivot. By adjusting the support frame, the distance between the lower leg and the thigh can be adjusted. Combined with the first elastic fixation strap, it achieves flexible restraint, which not only avoids the problem of improper force in traditional manual fixation by family members, but also reduces the body displacement caused by the child's limb struggle. Furthermore, when adjusting the support frame to move the distance between the lower leg and the thigh, the child's buttocks can be slightly raised, which facilitates the doctor's precise control of the enema angle and pressure.

[0016] 2. The soft cotton cloth layer on the inner wall of the fixation strap can protect the delicate skin of infants and young children; together with the protective railings on both sides of the operating table, it can effectively limit the child's hand grabbing and limb twisting, further reducing the risk of operation interruption caused by the child's agitation and shortening the overall rehabilitation time.

[0017] 3. The anal canal fixation device can be adjusted forward and backward along with the limb fixation base; the rotating connection between the connecting plate and the base can flexibly adapt to the insertion angle of the anal canal, ensuring that the anal canal is accurately aligned with the child's anus; the anal canal receiving groove on the fixation plate, combined with the anti-slip silicone ring with anti-slip texture on the inner wall, can stably support the anal canal from the bottom, avoiding the skin allergy and insufficient fixation strength problems of traditional adhesive tape fixation; the elastic metal limiting pressure plate can form a soft pressure on the top of the anal canal, combined with the anti-slip effect of the bottom anti-slip silicone ring, forming a double fixation structure of support + pressure, effectively preventing the anal canal from shifting, changing depth or prolapse when the child struggles, ensuring stable intestinal pressure, avoiding the reduced repositioning efficiency caused by pressure leakage, and reducing the irregular traction of the intestinal wall caused by pressure fluctuations, significantly reducing the risk of complications such as anal mucosal damage and intestinal perforation.

[0018] 4. The protective device can be flexibly deployed according to the needs of fluoroscopic operation and hung with the protective railing on one side; ensuring that the lead curtain accurately covers the non-operation area of ​​the child, exposing only the abdominal operation area, solving the problem of inaccurate coverage of traditional overall radiation protection equipment, and minimizing the child's X-ray radiation exposure dose while ensuring the clarity of fluoroscopic observation, thus reducing potential health risks.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 and Figure 2 As shown, a novel pediatric intussusception reduction and fixation protective device includes a pediatric intussusception reduction operating table 1, a limb fixation device 2 for fixing the child's limbs, a protective device 3 for protecting the child during fluoroscopic observation, and an anal canal fixation device 4 for fixing the anal canal. The operating table 1 is the basic support structure of the entire device, made of medical-grade ABS material, with a smooth and easy-to-clean surface, and has good load-bearing capacity and stability. An examination footboard 10 is provided near one end of the top of the operating table 1 to facilitate standing during fluoroscopic examination. A first sliding groove 11 is opened on the top of the operating table 1 near the longer sides on both sides. A first inlet 111 is opened on the first sliding groove 11. A guardrail 12, a handrail 13, and a sliding limb fixation seat 14 are slidably installed in each first sliding groove 11. A limiting bolt for limiting the position is provided on the handrail 13 (see the attached document for details). Figure 1 and 2The handrail 13 allows medical staff to quickly install or remove the guardrail 12 and handrail 13 through the first inlet 111, and also adjust their positions along the first slide 11 to accommodate the lying needs of infants and toddlers of different heights. A hand restraint strap 131 is connected to the handrail 13. The hand restraint strap 131 is an elastic webbing with its free end detachably connected via Velcro. The inner wall of the hand restraint strap 131 is lined with a soft cotton fabric layer to prevent direct contact between the elastic webbing and the infant's delicate skin, reducing friction damage. When in use, after a child grasps the handrail 13, the hand restraint strap 131 can secure the child's hand, effectively limiting limb struggles and adapting to slight movements of the infant, reducing resistance caused by a feeling of constraint.

[0027] The limb fixation base 14 is equipped with limiting bolts for positioning (see appendix for details). Figure 1 and 2 The limb fixation seat 14 in the middle can be quickly installed or removed by medical staff through the first inlet 111. The position of the limb fixation seat 14 can also be adjusted along the first slide 11 to adapt to the lying lower limb fixation needs of infants and young children of different heights.

[0028] Please see Figure 2 and Figure 3 As shown, the limb fixation device 2 is located on two limb fixation seats 14 and is used to stably restrain the infant's lower limbs to prevent limb struggle from interfering with the operation. The limb fixation device 2 includes a lower limb fixation seat 21 and a support frame 22 to support the child's lower legs. The lower limb fixation seat 21 includes a seat body 211, the bottom of which is fixed to the top of the limb fixation seat 14. The position of the limb fixation seat 14 can be adjusted to adapt to the length of the infant's lower limbs. The seat body 211 is provided with a position limiting bolt (see details for the specific structure). Figure 2 and Figure 3 (As shown) The position of the limb fixation device 2 is limited by bolts. The top of the seat 211 has a first U-shaped mounting groove 214, in which a first rotating shaft 213 is installed to provide rotational support for the support frame 22. A first elastic fixing strap 221 is connected to the lower part of the support frame 22 near the front to fix the infant's ankle. A calf support plate 222 is connected to the upper part of the support frame 22 near the lower limb fixation seat 21. The curvature of the support plate conforms to the contour of the child's calf and can distribute the leg pressure. A connecting block 223 is connected to the outer wall of the calf support plate 222 away from the support frame 22. The connecting block 223 is engaged inside the first U-shaped mounting groove 214 and is rotatably connected to the first rotating shaft 213, so that the support frame 22 can be slightly adjusted around the first rotating shaft 213 to adapt to the natural posture of the infant's legs. When the support frame 22 is adjusted to move the distance between the calf and thigh, the child's buttocks can be slightly raised (see Appendix for details). Figure 3 (As shown), this allows doctors to precisely control the angle and pressure of the enema.

[0029] The device employs a graded lower limb fixation and flexible hand restraint design. The limb fixation seat 14 allows for sliding adjustment of the limb fixation device 2, and the support frame 22 can be rotated for fine adjustment, adapting to the limb postures of infants and young children of different body sizes. This avoids the problem of improper force when manually fixing the limbs by family members in traditional methods. Furthermore, adjusting the support frame 22 to move the distance between the lower leg and thigh can slightly raise the child's buttocks, facilitating precise control of the enema angle and pressure by the doctor. Both the first elastic fixation strap 221 and the Velcro hand fixation strap 131 are flexible restraints, effectively limiting limb struggles and adapting to slight movements of the infant and young child, reducing resistance caused by a feeling of restraint. The soft cotton layer and the conformal support plate design further ensure the comfort of the infant's skin and limbs, reducing the risk of pressure injury.

[0030] Please see Figure 2 and Figure 4 As shown, the protective device 3 includes a hollow retractable rod 31 and a radiation-proof lead curtain 32 fixedly wound around one side of the outer wall of the hollow retractable rod 31. The hollow retractable rod 31 is rotatably mounted on two handrails 13 on one side of the operating table 1. Hooks 33 are connected to both ends of the handrails 13 for hanging on the other handrail 13. The radiation-proof lead curtain 32 is used to protect the non-operational area of ​​infants and young children during air enema X-ray fluoroscopy, reducing radiation exposure. There are two protective devices 3, which are distributed and fixed on the two handrails 13 on the longer side of the operating table 1, and the two are distributed above and below the abdomen, ensuring that the lead curtain accurately covers the non-operational area of ​​the child, exposing only the abdominal operation area. This solves the problem of inaccurate coverage of traditional overall radiation protection equipment, and while ensuring the clarity of fluoroscopic observation, it minimizes the X-ray radiation exposure dose of the child and reduces potential health risks. The end of the radiation-proof lead curtain 32 is fixed to another handrail 13 on the outer edge of the operating table 1 by the hooks 33. After use, the radiation-proof lead curtain 32 can be rolled up by holding the hollow retractable rod 31 for easy storage.

[0031] The roll-up radiation shielding lead curtain 32 can be flexibly unfolded to accurately cover non-operational areas such as the infant's genitals and lower limbs, exposing only the abdominal treatment area. The hollow roll-up rod 31 is made of rubber to avoid collisions and injuries to the infant from metal parts, ensuring both radiation protection effectiveness and safety.

[0032] Please see Figure 2 and Figure 5As shown, a crossbar 141 connects the two limb fixation seats 14. The anal tube fixation device 4 is located on the crossbar 141. The anal tube fixation device 4 includes a base 41 and a connecting plate 42 rotatably connected to the top of the base 41. The connecting plate 42 can be adjusted around the rotation point to easily adapt to the tilt angle of the anal tube insertion. A fixing plate 43 is fixedly connected to the top of the connecting plate 42 to provide stable support for the anal tube fixation. The top surface of the fixing plate 43 has an anal tube receiving groove 44 adapted to the outer diameter of the anal tube. An anti-slip silicone ring is pasted on the inner wall of the anal tube receiving groove 44. The inner wall of the anti-slip silicone ring has anti-slip texture to increase friction and prevent the anal tube from sliding along the groove. Limiting pressure plates 45 are symmetrically connected on both sides of the anal tube receiving groove 44. The limiting pressure plates 45 are elastic metal sheets with a certain deformation capacity, which can form a flexible press on the top of the anal tube, forming a double fixation of support and pressure in conjunction with the bottom anti-slip silicone ring.

[0033] The anal tube fixation device 4 can flexibly adapt to the insertion position and angle of the anal tube for different infants and young children, ensuring that the anal tube is accurately aligned with the anus; the triple fixation structure of the groove support + anti-slip silicone ring + elastic pressure plate effectively avoids the skin allergy problem and insufficient fixation strength of traditional adhesive tape fixation, prevents the anal tube from shifting or prolapsed when the child struggles, and ensures stable intestinal pressure, which not only improves the success rate of repositioning, but also reduces the risk of intestinal mucosal damage and intestinal perforation caused by pressure fluctuations.

[0034] Workflow: Place the infant flat on the operating table 1. Adjust the position of the lower limb fixation seat 21 along the first slide groove 11 using the limb fixation seat 14, so that the support frame 22 fits against the infant's lower leg and the sole of the infant's foot rests against the bottom rod of the support frame 22. Rotate the support frame 22 to the appropriate angle and secure the ankle with the first elastic fixing strap 221. Place the infant's hand inside the armrest 13 and secure the hand flexibly with the Velcro hand fixing strap 131, adjusting the tightness to not affect blood circulation. Rotate the hollow retractable rod 31 to unfold the radiation-proof lead curtain 32, so that the lead curtain covers the infant. For non-operational areas of infants and young children (such as chest, genitals, legs, etc.), hang the end hook 33 of the radiation-proof lead curtain 32 on the protective railing 12 on the other side, rotate the connecting plate 42 to the appropriate angle, put the anal tube into the anal tube receiving groove 44, and fix it with the anti-slip silicone ring and elastic limiting pressure plate 45. Then perform the anal tube insertion operation; perform air enema reduction, and observe the reduction progress through X-ray during the process. Since the child's limbs and anal tube are stably fixed, the operation accuracy can be ensured. After the reduction is completed, remove the anal tube fixing device 4, hand and lower limb fixing straps in sequence.
