Description

Technical Field

[0001] The present invention relates to the technical field of pediatric surgery, and in particular to a pediatric body position restraint device. Background Art

[0002] Pediatric surgery is a field of surgical treatment specifically for children (from newborns to adolescents). Its core goal is to address illness, congenital defects, or trauma through surgical intervention, while also addressing the child's growth and developmental needs. However, because infants and children have immature self-awareness and lack a rational understanding of illness and medical treatment, various difficulties with medical staff during and after surgery are unavoidable.

[0003] For example, children may move their limbs due to pain or fear, whether they are unconscious or conscious, which may interfere with surgical operations and increase the risk of bleeding, organ damage, etc. After surgery or in intensive care, children may unconsciously remove endotracheal tubes, intravenous catheters, or drainage tubes, which may be life-threatening. Children may also scratch wounds or dressings after surgery, causing bleeding, infection, or delayed healing. Therefore, for pediatric patients undergoing surgery, during or after the operation, medical staff will usually tie them up with straps and other means to appropriately restrain the children's limbs, thereby limiting the children's restless movements to a certain extent and avoiding the adverse effects caused by the children's restlessness.

[0004] However, this simple limb binding restraint is not easy to fix on the hospital bed. At the same time, since there is no restriction on the torso, restraining the limbs alone cannot prevent the child from causing larger limb movements through twisting of the torso when in a state of agitation. Ultimately, the actual restraint effect on the child is poor and the operation is inconvenient. Summary of the Invention

[0005] In view of this, the present invention proposes a pediatric body position restraint device to effectively and conveniently restrain the child, facilitate the surgical process, prevent the wound from being scratched and the drainage tube from falling off due to the child's restlessness, and ensure the safety of the child and the surgical effect.

[0006] In order to achieve the above technical effects, the technical solution adopted by the present invention is:

[0007] Pediatric positional restraints, including:

[0008] A tabletop, used to support the child's body;

[0009] A trunk restraint device is provided in the middle of the table, and one is provided on each side of the patient's armpits. The trunk restraint device has a first position in which it is flat on the table after being unfolded, and a second position in which it is bent to clamp the patient's torso from both sides of the patient's armpits;

[0010] There are four limb restraining devices detachably provided on the table, the four limb restraining devices are used to restrain the limbs of the child respectively, and the positions of the four limb restraining devices are adjustable; and

[0011] The cushion body is laid flat on the table surface and is provided with openings for exposing the trunk limiting device and the limb limiting devices.

[0012] Using the above technical solution, the child lies flat on a cushioned table. The trunk restraint device clamps and secures the trunk from both sides of the armpits. After the four limb restraint devices are adjusted, the hands and feet are respectively secured near the wrists. Through multi-point fixation, the child's body is restrained in a relatively comfortable posture. The fixation operation is convenient, eliminating large movements of the child's body, ensuring the restraint effect, avoiding the movement of the child's limbs that interfere with the surgical operation, and preventing the wound from being scratched and the drainage tube from falling off due to the child's restlessness. At the same time, the fixation position is selected in the armpits and wrists of the hands and feet, where the child's surgical incisions are less likely to occur, to minimize interference with the surgical operation and the impact of postoperative wounds. It is more convenient for medical staff to restrain and adjust the child and facilitates the fixation of various drainage tubes.

[0013] Furthermore, each of the trunk limiting devices comprises: a clamping body and a traction mechanism;

[0014] The clamping body is composed of a plurality of clamping blocks hinged in sequence, with one end of the clamping block fixed to the table surface corresponding to the patient's armpit, and the other end of the clamping body extending away from the patient's body to form the first position; the cross-section of the clamping block along the extension direction of the clamping body is trapezoidal, and the lower base of the trapezoidal cross-section faces the table surface; adjacent edges of adjacent clamping blocks facing the table surface are hinged to each other, and the position of the clamping block facing away from the table surface is provided with a traction hole along the extension direction of the clamping body;

[0015] The traction mechanism includes: a traction rope and a traction power mechanism, one end of the traction rope is fixedly connected to the clamping block at the end away from the armpit of the child, and the other end of the traction rope passes through the traction holes of each of the clamping bodies in turn, extends from the clamping block at the end close to the armpit of the child, and is connected to the traction power mechanism; the traction power mechanism pulls the traction rope to make the edges of the clamping blocks facing away from the table surface approach each other, and the clamping body bends in the direction close to the torso of the child to form the second position.

[0016] The hinged structure of the clamping body with multiple trapezoidal clamping blocks, based on the difference in linear lengths between the upper and lower bases of the trapezoid, naturally maintains the first position flat on the table surface in the absence of external traction, and only requires simple traction at a position outside the table surface to bend the clamping body toward the child's torso and transform it to the second position, thereby simply and effectively clamping the child's torso from both sides of the child's armpits, and by controlling the magnitude of the traction force, the bending deformation and clamping force of the clamping body can be conveniently controlled, thereby having a wider range of applications and simple and efficient operation.

[0017] Furthermore, a buffer airbag is provided on the surface of the clamping body facing away from the table top.

[0018] The cushioning airbag is used as a buffer between the clamping body and the child's body. The contact surfaces on both sides of the child's torso can naturally adapt with the contact deformation of the cushioning airbag, eliminating the clamping gap, achieving sufficient covering clamping, and ensuring the clamping effect; and the clamping force is more moderate, avoiding damage to the child's body; at the same time, it also reserves a certain elastic space for the child's body to twist. After feeling uncomfortable after being restrained for a long time, the child can twist, adjust and change his posture within a certain range, so as to relieve discomfort, reduce the restlessness caused by forced restraint, prolong the calm time of the child's restraint, and reduce the negative effects caused by restlessness.

[0019] Furthermore, a cylinder is provided in each of the clamping blocks, the piston rod of the cylinder is arranged parallel to the axis of the traction hole on the corresponding clamping block, the outer end of the piston rod extends outside the clamping block and is connected to an adjacent clamping block; the rodless cavity of the cylinder is connected to the buffer airbag.

[0020] By arranging a cylinder in the clamping block, when the clamping body deforms from the first position to the second position, the distance between the upper and lower trapezoidal parts of the clamping blocks decreases, the piston rod of the cylinder retracts, and the volume of the rodless cavity decreases, thereby inflating the cushioning airbag. As a result, the greater the deformation of the clamping body, the tighter the clamping of the child's torso, the fuller the cushioning airbag is inflated, and the greater the elastic cushioning of the child's torso. This avoids damage to the child's torso caused by excessive clamping force, further ensuring the comfort and safety of the torso clamping. At the same time, when the traction force applied by the pulling power mechanism is canceled, the inflated cushioning airbag naturally exhausts air into the rodless cavity of the cylinder, pushing the piston rod of the cylinder to extend, and then driving the clamping body to deform to the first position, achieving a natural return to a flat state without the need for external force, making it more convenient to use.

[0021] Furthermore, the buffer airbag and each clamping block are linearly connected along a direction perpendicular to the axis of the traction hole.

[0022] The cushioning airbag is linearly connected to each clamping block to achieve multi-position evenly spaced connections between the cushioning airbag and the clamping body, which plays a role in uniformly restraining the deformation of the cushioning airbag. In the process of deformation of the clamping body, the deformation of the cushioning airbag is not only properly restrained, but also can be evenly inflated during the deformation process, maintaining a clamping posture that matches the child's body.

[0023] Furthermore, a flexible cushion layer is provided on the surface of the buffer airbag facing away from the table top.

[0024] A flexible cushion layer is set on the surface of the cushioning airbag to prevent the cushioning airbag from being exposed and damaged while maintaining flexible contact with the child's body; at the same time, the flexible cushion layer and the clamping body form a clamp on both sides of the cushioning airbag, further constraining the deformation of the cushioning airbag, controlling the deformation of the cushioning airbag within the required range, and keeping the clamping contact surface in a bent state.

[0025] Furthermore, the clamping block can be fixed to the table by magnetic attraction.

[0026] When the clamping body is flattened against the table and is in the first position, the clamping body is fixed by magnetic attraction to better maintain the first position, which facilitates the movement and long-term placement of the entire device.

[0027] Furthermore, the limb limiting device includes: a fixing seat, a limiting ring and an annular airbag, the fixing seat is detachably connected to the table top, the limiting ring is sleeved outside the annular airbag, and the limiting ring is slidably connected to the fixing seat.

[0028] A single limb limiting device is fixed on the exposed table surface through a fixing seat, and the angle and posture can be adjusted at will. Therefore, after the child's limbs pass through the annular airbag, the annular airbag is inflated to restrain the limbs, thereby achieving safe and effective restriction of the limbs; and due to the sliding cooperation relationship between the limiting ring and the fixing seat, the child's limbs still maintain a certain swinging space, and can move appropriately to alleviate the discomfort caused by the joint restraint, relieve the child's restlessness, and extend the safe and effective restraint time.

[0029] Furthermore, a T-shaped sliding groove is provided on the surface of the fixing seat facing away from the table surface, and a T-shaped slider is provided on one circumferential side of the limiting ring, and the T-shaped slider is slidably adapted to the T-shaped sliding groove.

[0030] The sliding fit is achieved through the T-shaped structure, which has a simple structure and controllable sliding.

[0031] Furthermore, a friction plate is provided in the T-shaped slide groove, and an adjusting nut for pressing the friction plate is provided on the fixing seat.

[0032] The design of adding a friction plate can adjust the gap and pressure between the T-type slider and the friction plate by adjusting the top pressure of the nut, thereby adjusting the sliding resistance of the T-type slider, that is, controlling the difficulty of the child moving his limbs, better adapting to the restraint requirements of children with different personalities, different physical conditions, and different rehabilitation stages, and improving practicality.

[0033] In summary, by adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0034] 1. By restricting the trunk, the child's body can be prevented from making large movements. By restraining the limbs, the restrictive effect of the restraint is ensured, and the movement of the child's limbs is avoided from interfering with the surgical operation, thereby preventing the wound from being scratched and the drainage tube from falling off due to the child's restlessness.

[0035] 2. Designed for pediatric patients, it is easy for medical staff to operate, reduces interference with surgical operations and the impact of postoperative wounds, and facilitates the fixation of various drainage tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0057] like Figures 1 to 9 As shown in FIG, the pediatric body position restraint device disclosed in the present application comprises a main structure including a table 10, a trunk restraint device 20, a limb restraint device 30, and a cushion 40. The table 10 is used to support the patient's body I. However, in actual application, the table 10 is not necessarily a table-shaped structure, but can be a structure similar to a hospital bed, an operating table, a nursing bed, a nursing table, etc. Figure 1 and Figure 2The trunk restraint device 20 is located in the middle of the table 10, one for each side of the patient's armpits. The trunk restraint device 20 has a first position II, where it lies flat on the table 10 after being unfolded, and a second position III, where it is bent to clamp the patient's torso from both sides of the patient's armpits I. Four limb restraint devices 30 are detachably mounted on the table 10. These four limb restraint devices 30 are used to restrain the patient's limbs, and their positions are adjustable to accommodate limb restraint requirements for different heights, body shapes, and restraint postures.

[0058] The cushion body 40 is laid flat on the table 10 to improve the comfort of the child lying flat on the table 10 for a long time. At the same time, openings are opened on the cushion body 40 to expose the trunk restraint device 20 and the limb restraint device 30. Considering that the cushion body 40 needs to flexibly support the main part of the child's body 1, the specific positions of the trunk restraint device 20 and the limb restraint device 30 can be as follows: Figure 1 and 2 As shown, corresponding lower limb fixing openings 41, upper limb fixing openings 42 and clamping body accommodating openings 43 are opened. Specifically, corresponding to the trunk limiting devices 20 on both sides, a clamping body accommodating opening 43 is opened on each side of the pad 40 under the armpit of the corresponding child, so that when the trunk limiting device 20 is in the first position II, it is accommodated in the clamping body accommodating opening 43 to form an approximate plane, which is convenient for use as an ordinary flat bed without restraint. Similarly, based on the detachable fixing method of the limb limiting device 30, the lower limb fixing openings 41 and the upper limb fixing openings 42 can also be filled with suitable pads when the limb limiting device 30 is not in use to form a flat surface, thereby expanding usability. The setting area of the lower limb fixing opening 41 should cover the swing range of the feet of infants and younger children, because its area is not separated by the torso, and can be as Figure 2 The openings of the two limb restraints 30 corresponding to the feet are connected to form a lower limb fixing port 41, maximizing the adjustment range. An upper limb fixing port 42 is provided on each side of the child's torso. Because these ports are located adjacent to the clamp body receiving port 43, the upper limb fixing port 42 on the corresponding side can be connected to the clamp body receiving port 43, similarly achieving a wider adjustment range.

[0059] Using the above technical solution, the child's body I lies flat on a table 10 covered with a cushion 40. The trunk restraint device 20 clamps and secures the trunk from both sides of the armpits. The four limb restraint devices 30, after adjusting their positions, respectively secure the hands and feet near the wrists. This multi-point fixation restrains the child's body I in a relatively comfortable posture. The fixation operation is convenient, preventing the child's body from moving significantly, ensuring the restraint effect, avoiding interference with the surgical procedure due to the child's limb movement, and preventing the wound from being scratched or drainage tubes from falling out due to the child's restlessness. Furthermore, the fixation locations are selected in the armpits and wrists of the hands and feet, where surgical incisions are less common, to minimize interference with the surgical procedure and the impact of postoperative wounds. It is convenient for medical staff to restrain and adjust the child and facilitates the fixation of various drainage tubes.

[0060] like Figure 3-7 As shown in one embodiment, each trunk limiting device 20 includes: a clamping body 21 and a traction mechanism 22. The clamping body 21 is composed of a plurality of clamping blocks 211 hinged in sequence, and the clamping block 211 at one end is fixed on the table 10 corresponding to the patient's armpit, and the other end of the clamping body 21 extends away from the patient's body I, forming a Figure 4 The first position II is shown. The cross-section of the clamping block 211 along the extension direction of the clamping body 21 is trapezoidal, with the lower base of the trapezoidal cross-section facing the table 10. The adjacent edges of adjacent clamping blocks 211 facing the table 10 are hinged to each other. The specific hinge structure can be provided with connecting holes on the adjacent edges of adjacent clamping blocks 211 facing the table 10, and the axial connection is achieved through a rotating shaft 213. The position of the clamping block 211 facing away from the table 10 is provided with a traction hole 212 along the extension direction of the clamping body 21. The traction mechanism 22 includes: a traction rope 221 and a traction power mechanism 222, one end of the traction rope 221 is fixedly connected to the clamping block 211 at the end away from the patient's armpit, and the other end of the traction rope 221 passes through the traction holes 212 of each clamping body 21 in turn, extends from the clamping block 211 at the end near the patient's armpit, and is connected to the traction power mechanism 222; the traction power mechanism 222 pulls the traction rope 221, so that the edges of the clamping block 211 facing away from the table 10 are close to each other, and the clamping body 21 is bent in the direction close to the patient's torso to form a Figure 3 and Figure 6 The second position III is shown.

[0061] The above-mentioned torso limiting device 20, the clamping body 21 is an articulated structure composed of multiple trapezoidal clamping blocks 211. Based on the difference in linear lengths between the upper and lower bases of the trapezoid, it naturally maintains the first position II where the table 10 is flat without external traction, and only needs simple traction at a position outside the table 10 to bend the clamping body 21 in the direction close to the child's torso to the second position III, thereby simply and effectively clamping the child's torso from both sides of the child's armpits, and by controlling the magnitude of the traction force, the bending deformation and clamping force of the clamping body 21 can be conveniently controlled, thereby having a wider range of applications and simple and efficient operation.

[0062] It should be noted that the specific meanings of the terms such as trapezoid, upper base, and lower base in the above description refer to the definition of trapezoid, that is: a trapezoid refers to a quadrilateral with one set of opposite sides parallel and the other set of opposite sides not parallel. The two parallel sides are called the bases of the trapezoid, the longer base is called the lower base, and the shorter base is called the upper base.

[0063] See also Figure 3 , the specific structure of the pulling power mechanism 222 can adopt the structure of a pulley 2221 plus a drive shaft 2222. That is, a pulley 2221 is set at the bottom of the table top or other positions that do not affect the bearing effect of the table top, and one end of the traction rope 221 connected to the traction power mechanism 222 is led to the pulley 2221 and fixed. In order to facilitate the routing of the traction rope 221, a rope guide hole 13 can be opened at the required position on the cushion body 40 and the table top 10 so that the traction rope 221 can pass through it. The pulley 2221 is connected to the drive shaft 2222 and is driven by the drive shaft 2222. The specific drive can be a hand crank set at the end of the drive shaft 2222, or it can be connected to a motor to form an electric drive. Only one pulley 2221 can be set to reel in two traction ropes 221 at the same time, and the structure is compact and simple. The pulley 2221 is also like Figure 3 As shown, one clamping body 21 is provided on each of the corresponding two sides to respectively reel in two traction ropes 221; at this time, the driving shaft 2222 that drives the two pulleys 2221 can be the same shaft for synchronous driving, or can be two separate shafts driven separately, and when the two shafts are driven separately, a clutch device can also be provided between the two shafts to connect the two shafts to achieve unified drive when needed, without the need to disconnect them to form separate drives, thereby meeting the physical restraint needs of children in different situations such as asymmetric restraint or the need to lie on their side with a certain arc, and having a wider range of usage scenarios.

[0064] In one embodiment, considering the gaps between the clamping blocks 211 caused by the trapezoidal cross-sectional structure, a pinching point may be formed during the clamping deformation process, which may almost cause pinching injuries to the surface of the child's body I. Subsequently, a buffer airbag 23 is provided on the surface of the clamping body 21 facing away from the table 10, that is, the surface of the clamping body 21 that contacts the child's body I after deformation, to avoid direct contact between the gaps between the clamping blocks 211 and the child's body I, thereby eliminating the hidden danger of pinching injuries. At the same time, the cushioning airbag 23 is used as a buffer between the clamping body 21 and the child's body I, and the contact surfaces on both sides of the child's torso can naturally adapt with the contact deformation of the cushioning airbag 23, eliminating the clamping gap, achieving sufficient covering clamping, and ensuring the clamping effect; and the clamping force is more moderate, avoiding damage to the child's body I caused by hard clamping; at the same time, a certain elastic space is reserved for the child's body twisting. After feeling uncomfortable after being restrained for a long time, the child can twist, adjust and change his posture within a certain range, relieve discomfort, reduce the restlessness caused by forced restraint, prolong the calm time of the child's restraint, and reduce the negative effects caused by restlessness.

[0065] In one embodiment, a cylinder 24 is disposed within each clamping block 211. The piston rod 242 of the cylinder 24 is arranged parallel to the axis of the traction hole 212 of the corresponding clamping block 211. The outer end of the piston rod 242 extends outside the clamping block 211 and connects to the adjacent clamping block 211. The rodless cavity 244 of the cylinder 24 communicates with the cushioning airbag 23. By disposing the cylinder 24 within the clamping block 211, when the clamping body 21 deforms from the first position II to the second position III, the distance between the trapezoidal upper bases of the clamping blocks 211 decreases, the piston rod 242 of the cylinder 24 retracts, and the volume of the rodless cavity 244 decreases, thereby inflating the cushioning airbag 23. Consequently, the greater the deformation of the clamping body 21, the tighter the clamping of the child's torso, and the fuller the inflation of the cushioning airbag 23, the greater the elastic cushioning of the child's torso. This prevents damage to the child's torso caused by excessive clamping force, further ensuring comfortable and safe torso clamping.

[0066] At the same time, when the traction force applied by the pulling power mechanism 222 is canceled, the inflated cushioning airbag 23 is naturally exhausted to the rodless chamber 244 of the outer cylinder 24, pushing the piston rod 242 of the cylinder 24 outward, thereby driving the clamping body 21 to deform toward the first position II, so that the clamping body 21 can naturally return to the flat state without the action of external force, making it more convenient to use. In order to enable the clamping body 21 to maintain the first position II for a long time, a structure can be further provided in which the clamping block 211 can be magnetically fixed to the table 10, as shown in the following example. Figure 3As shown, a magnet 214 can be set on the trapezoidal lower bottom surface of each clamping block 211, and at the same time, a ferromagnetic plate 12 that can produce a magnetic adsorption effect with the magnet 214 is set on the surface of the table 10 exposed by the clamping body accommodating opening 43, such as a simple iron plate. Then, when the clamping body 21 is flattened on the table 10 and is in the first position II, it is fixed by the magnetic attraction of the magnet 214 and the ferromagnetic plate 12, and is better maintained in the first position II, which is convenient for the movement and long-term placement of the entire device. When in use, the contact between the magnet 214 and the ferromagnetic plate 12 can be disconnected by external force.

[0067] In the specific implementation structure, the cylinder 24 in each clamping block 211 can be a finished cylinder directly installed in the clamping block 211, or it can be a structure with equivalent function of the cylinder made inside the clamping block 211 as the main body, that is, a piston chamber 2111 is opened in the clamping block 211, and the extension direction of the piston chamber 2111 is also parallel to the axis of the traction hole 212 on the corresponding clamping block 211. Then, a piston 241 is set in the piston chamber 2111, and one end of a piston rod 242 is connected to the piston 241, and the other end extends to the outside of the clamping block 211 to form a cylinder structure. The limited space in the clamping block 211 is utilized to minimize the unnecessary structure occupation, make the structure more compact, increase the volume of the piston chamber 2111, and increase the volume that the cylinder 24 can inflate and discharge during the deformation of the clamping body 21.

[0068] Furthermore, considering that the outer ends of the piston rods 242 and the side surfaces of the adjacent clamping blocks 211 are connected during the process of rotation and deformation around the rotation axis 213, displacement of the connection will occur on the side surfaces of the clamping blocks 211 as the adjacent side surfaces of the clamping blocks 211 move closer and further away. Figure 5 and Figure 7 An adjusting groove 2112 is provided on the side of the clamping block 211 along the displacement direction of the connection point, and a limit head 243 is provided at the outer end of the piston rod 242. The limit head 243 slides with the adjusting groove 2112. If a T-slot structure is adopted, it can not only ensure that the piston rod 242 is pulled to perform telescopic movement during the deformation process, but also adjust the relative position of the piston rod 242 and the side of the clamping block 211 during the movement process, thereby ensuring the smooth progress of the deformation action.

[0069] In one embodiment, the cushioning airbag 23 and each clamping block 211 are linearly connected along a direction perpendicular to the axis of the traction hole 212, that is, Figure 5 and Figure 7As shown, the cushioning airbag 23 is connected to each clamping block 211 in a straight line to form a connecting line 25, thereby linearly connecting the cushioning airbag 23 to each clamping block 211, realizing multi-position evenly spaced connections between the cushioning airbag 23 and the clamping body 21, and uniformly restraining the deformation of the cushioning airbag 23. Furthermore, during the deformation of the clamping body 21, the deformation of the cushioning airbag 23 is properly restrained and can be uniformly inflated during the deformation process, thereby maintaining a clamping posture that matches the child's body.

[0070] In one embodiment, a flexible cushion layer 26 is further provided on the surface of the cushioning airbag 23 facing away from the table top 10. Thus, by providing another layer of flexible cushion layer 26 on the surface of the cushioning airbag 23, the cushioning airbag 23 is prevented from being exposed and damaged while maintaining flexible contact with the child's body. At the same time, the flexible cushion layer 26 and the clamping body 21 form a clamp on both sides of the cushioning airbag 23, further constraining the deformation of the cushioning airbag 23, controlling the deformation of the cushioning airbag 23 within a required range, and keeping the clamping contact surface in a bent state.

[0071] like Figure 8 、 Figure 9 As shown, the limb limiting device 30 in the embodiment includes: a fixing seat 31, a limiting ring 32 and an annular airbag 33. The fixing seat 31 is detachably connected to the table top 10. Specifically, a magnetic connection can be adopted, and corresponding attractive magnetic bodies are respectively set between the fixing seat 31 and the table top 10. A suction cup connection can also be adopted, and an appropriate number of suction cups 34 are set at the bottom of the fixing seat 31. At the same time, the table top 10 where the lower limb fixing port 41 and the upper limb fixing port 42 are exposed is set to a smooth surface, so that the adsorption and fixation of the suction cup 34 can be achieved.

[0072] The retaining ring 32 is positioned over the annular airbag 33. The child's hand or foot is inserted through the central opening of the annular airbag 33. The annular airbag 33 is then inflated to secure the child's limb. The specific structure can be compared to the arm inflation and pressurization structure commonly found in electronic blood pressure monitors in hospitals, achieving simple and convenient inflation fixation. Furthermore, the annular airbag 33 can be further configured to rotate circumferentially relative to the retaining ring 32. This allows for appropriate axial twisting of the limb after securing it, alleviating discomfort associated with prolonged immobilization.

[0073] At the same time, the limiting ring 32 is connected to the fixing seat 31 in a sliding manner. The specific sliding connection method can be as follows: Figure 9As shown, a T-shaped groove 311 is provided on the surface of the fixed seat 31 facing away from the table 10, and a T-shaped slider 321 is provided on the circumferential side of the limiting ring 32. The T-shaped slider 321 is slidably adapted to the T-shaped groove 311, thereby achieving sliding fit through the T-shaped structure, with a simple structure and controllable sliding. If you want to further improve the controllability of sliding, you can increase the design of the friction plate 312, that is, set the friction plate 312 in the T-shaped groove 311, and set an adjusting nut 313 on the fixed seat 31 to press the friction plate 312. The adjusting nut 313 can be set in multiples depending on the length of the friction plate 312 and the T-shaped groove 311. Then, by adjusting the pressing length of the nut 313 on the friction plate 312, the gap and pressure between the T-shaped slider 321 and the friction plate 312 can be adjusted, thereby adjusting the sliding resistance of the T-shaped slider 321, that is, controlling the difficulty of the child moving his limbs, better adapting to the restraint requirements of children with different personalities, different physical conditions, and different rehabilitation stages, and having better practicality.

[0074] When the limb limiting device 30 is in use, a single limb limiting device 30 is fixed to the exposed table surface 10 through the fixing seat 31, and the angle and posture can be adjusted at will. Therefore, after the limbs of the child pass through the annular airbag 33, the annular airbag 33 is inflated to restrain the limbs, thereby achieving safe and effective restriction of the limbs; and due to the sliding cooperation relationship between the limiting ring 32 and the fixing seat 31, the limbs of the child still maintain a certain swinging space, and can move appropriately to reduce the discomfort caused by the restraint, reduce the occurrence of the child's restlessness, and extend the safe and effective restraint time.

[0075] In summary, the pediatric body position restraint device disclosed in this application can prevent the child's body from moving significantly by restricting the trunk position, and with the help of the restraint of the limbs, it ensures the restraining effect, avoids the child's limb movement interfering with the surgical operation, and prevents the wound from being scratched and the drainage tube from falling off due to the child's restlessness; and it is designed for pediatric patients, is easy for medical staff to operate, reduces interference with surgical operations and the impact of postoperative wounds, and facilitates the fixation of various drainage tubes.
