Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an intelligent restraint device for agitated pediatric patients. Background Technology
[0002] In recent years, with the continuous development of medical science and technology, the number of pediatric surgical patients has been increasing. Postoperative agitation during the recovery period after general anesthesia has become one of the most common problems in children after general anesthesia. Once agitation occurs, it will not only prolong the child's recovery time, but may also lead to serious adverse events (such as falls from the bed, wound dehiscence, bleeding, etc.), affecting the child's recovery and physical development, and endangering the child's safety.
[0003] In the existing technology, restraint devices for agitated children, such as limb restraint sets (wrist-ankle-waist combination), mainly consist of four nylon / elastic straps, which fix the child's two wrists, ankles and waist respectively, using metal buckles or Velcro, and are often equipped with memory foam pads to prevent pressure.
[0004] In clinical practice, restraint interventions for agitated children are often long-term. If the tension generated by prolonged, fixed restraint exceeds the skin's tolerance threshold, it can easily lead to pressure sores or impaired local blood circulation. However, these adverse effects caused by restraint are more frequent and pronounced in children. Therefore, there is an urgent need for an intelligent restraint device for agitated pediatric children that can adapt to fluctuations in the child's agitation level—that is, slightly increasing the restraint force during periods of intense agitation to prevent falls, and decreasing the restraint force during calm periods to alleviate discomfort. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides an intelligent restraint device for pediatric agitation. By collecting tension data of the child's agitation in real time, the device adaptively adjusts the tightness of the restraint based on the tension data. Simultaneously, it employs two interwoven chest and abdominal restraint straps to create a ring-like structure that disperses the pressure of the restraint on the child, thus overcoming the shortcomings of existing restraint devices that are difficult to adapt to the fluctuations in the child's agitation.
[0006] To achieve the above objectives, the technical solution of the present invention is as follows: an intelligent restraint device for pediatric agitated children, comprising a placement frame, the placement frame being placed on the surface of a conventional hospital bed, and a first device housing and a second device housing being fixedly connected to both sides of the placement frame respectively.
[0007] The first device housing and the second device housing are respectively provided on one side close to each other, and the first device housing is provided with a first belt assembly for adjusting the length of the first chest and abdomen belt, and the second device housing is provided with a second belt assembly for adjusting the second chest and abdomen belt.
[0008] Both the first and second device housings are equipped with restraint range adjustment components. The two restraint range adjustment components are used to adjust the end spacing of the first and second chest and abdomen restraint belts, respectively. The first chest and abdomen restraint belt has two threading holes. During the wearing of the first and second chest and abdomen restraint belts, the end of the second chest and abdomen restraint belt away from the second roll assembly passes through the two threading holes from bottom to top and is then connected to the corresponding restraint range adjustment component.
[0009] The inner side of the first chest and abdominal restraint belt is equipped with an airbag adjustment component for adjusting the tightness of the restraint. The second chest and abdominal restraint belt is equipped with a tension acquisition component for collecting the child's agitation level. The tension acquisition component is connected to a controller. The controller receives the tension change data of the second chest and abdominal restraint belt collected in real time by the tension acquisition component to analyze and assess the child's agitation level. Based on the child's agitation level, the controller dynamically adjusts the inflation volume of the airbag adjustment component to achieve dynamic adjustment of the tightness of the restraint.
[0010] The technical principle of the above solution is as follows: This solution, through the integrated design of the placement frame combined with the first and second device shells, allows the restraint device to be placed on the surface of the hospital bed. The first and second chest and abdominal restraint straps on the first and second device shells intertwine to form a ring-shaped structure that conforms to the physiological curve of the child's chest and abdomen. The lengths of the first and second chest and abdominal restraint straps are adjusted by the first and second tape adjustment components to adapt to different body types. The distance between the two ends of the first and second chest and abdominal restraint straps is adjusted by the restraint range adjustment component to adapt to the differences in the child's physiological structure. At the same time, the tension acquisition component located on the second chest and abdominal restraint strap acquires the tension change data of the second chest and abdominal restraint strap in real time when the child is agitated. The controller dynamically adjusts the inflation volume of the airbag adjustment component based on the tension change data to assess the degree of agitation of the child, thereby achieving adaptive dynamic adjustment of the tightness of the restraint on the child.
[0011] The above approach has the following beneficial effects:
[0012] 1. This solution addresses the drawbacks of long-term fixed restraint, which can easily lead to pressure sores or local blood circulation disorders. By dynamically adjusting the restraint space formed by the interlacing of the first and second chest and abdominal restraint straps using an airbag adjustment component, the tightness of the restraint can be adjusted to avoid continuous tension exceeding the tolerance threshold of the child's skin tissue, thus effectively reducing the risk of complications from long-term restraint.
[0013] 2. This solution addresses the shortcomings of existing restraint devices that cannot adapt to fluctuations in the child's agitation level. This design dynamically adjusts the restraint force based on the real-time tension data of the second chest and abdominal restraint belt. When the child is agitated, the restraint force is appropriately increased to prevent damage to the surgical area, and the restraint force is reduced to alleviate discomfort when the child is calm, thus balancing the effectiveness of restraint with the child's comfort.
[0014] 3. This solution addresses the shortcomings of existing limb restraints, such as high escape rates and emotional resistance from children. The design employs a ring-shaped chest and abdomen restraint structure formed by the interweaving of a first and second chest and abdomen restraint belt. This disperses restraint pressure, reducing the probability of escape and emotional resistance caused by the child's struggle, and minimizing the risk of restraint-related complications. Simultaneously, it reduces the probability of the child breaking free from the restraint at a single point. Considering the characteristics of the child's intention to escape, this design increases both restraint comfort and restraint durability.
[0015] Furthermore, both the first and second tape reel assemblies include tape receiving grooves, and each tape receiving groove is rotatably connected to a winding shaft. The first and second chest and abdominal restraint straps are respectively fixedly connected to the corresponding winding shafts.
[0016] Both the first and second device housings have drive cavities, and drive components are fixedly connected inside each drive cavity. The output shaft of the drive component extends through the side wall of the corresponding drive cavity into the tape groove. The output shaft of the drive component is coaxially and fixedly connected to the corresponding winding shaft. Both drive components are signal-connected to the controller. The controller synchronously adjusts the signals of the two drive components based on the tension data of the second chest and abdominal restraint belt collected by the tension acquisition component, so as to achieve pre-restraint of the child by the first and second chest and abdominal restraint belts.
[0017] Beneficial effects: This design utilizes the power output of the drive component and the signal adjustment of the controller based on the real-time tension data of the second chest and abdomen restraint belt to automatically adapt to the chest and abdomen circumference of children of different body sizes. It eliminates the need for medical staff or family members to manually adjust the length of the first and second chest and abdomen restraint belts, improving operational efficiency. At the same time, it ensures that the initial length of the pre-restraint is appropriate, laying the foundation for subsequent dynamic adjustment.
[0018] Furthermore, based on the tension data of the second chest and abdominal restraint belt collected by the tension acquisition component, the controller synchronously controls the two drive components to achieve pre-restraint in the following specific process:
[0019] The controller first acquires several real-time tension data and compares them with the preset reference tension threshold range in real time;
[0020] If the current real-time tension data is detected to be lower than the lower limit of the reference tension threshold range, the controller immediately sends a tightening control signal to the two drive components simultaneously. The two drive components drive the first and second chest and abdomen restraint belts to shorten until the real-time tension data is within the reference tension threshold range.
[0021] If the real-time tension data is detected to be higher than the upper limit of the reference threshold range, the controller will simultaneously send a relaxation control signal, and the two drive components will drive the first and second chest and abdominal restraint belts to extend until the real-time tension data is within the reference tension threshold range.
[0022] The baseline tension threshold range is preset by medical staff before restraint based on the child's physiological characteristics.
[0023] Beneficial effects: Through signal transmission from the controller, tension acquisition component and two drive components, the pre-restraint tightness is automatically and precisely adjusted, avoiding errors from manual adjustment, ensuring that the pre-restraint tightness meets safety standards while taking into account the comfort of the child, and reducing the risk of complications caused by improper tightness.
[0024] Furthermore, the restraint range adjustment components each include height adjustment grooves and fixed belt buckles. The two height adjustment grooves are respectively opened on the first device housing and the second device housing. The fixed belt buckles are slidably engaged with the corresponding height adjustment grooves. The ends of the first chest and abdomen restraint belts and the second chest and abdomen restraint belts away from the belt receiving grooves are fixedly connected to fixed belt heads. The two fixed belt heads are detachably connected to the fixed belt buckles.
[0025] Each of the height adjustment slots has several hanging rod slots on the side furthest from each other, and each of the fasteners has a locking rod fixedly connected to the side of the belt buckle furthest from the belt head. The locking rods can fit into the hanging rod slots and be secured.
[0026] Beneficial effects: By sliding the fastener in the height adjustment groove, and by adjusting the fixed height of the end of the restraint strap in conjunction with the locking bar and the hanging bar groove, the end spacing can be changed to adapt to the vertical height difference between the chest and abdomen of different children and the bed surface, thereby improving the fit between the restraint strap and the child's chest and abdomen, avoiding uneven local pressure distribution, and further ensuring the safety and comfort of the restraint.
[0027] Furthermore, the airbag adjustment assembly includes an adjustment airbag and an air pump. The adjustment airbag is fixedly connected to the inside of the first chest and abdomen restraint belt, and the air pump is embedded in the first device housing. The output end of the air pump is connected to the adjustment airbag, and the air pump is signal-connected to the controller.
[0028] Beneficial effects: The air pump inflates or deflates the regulating airbag, and the controller dynamically adjusts the inflation volume according to the child's agitation level. The flexible expansion characteristics of the regulating airbag are used to adjust the tightness of the restraint, evenly distribute the restraint pressure, buffer the tension fluctuations during agitation, reduce the feeling of restraint resistance, and at the same time achieve dynamic adjustment of the restraint force to adapt to the changes in the child's agitation.
[0029] Furthermore, the coverage width of the airbag is adjusted to be the same as the width spacing between the two strap openings on the first chest and abdomen restraint belt.
[0030] Beneficial effects: This ensures that the adjustable airbag provides comprehensive and uniform pressure coverage and tightness adjustment to the effective restraint area of the chest and abdomen when inflated. It does not interfere with the wrapping and fixation of the second chest and abdomen restraint belt, and avoids problems such as decreased fit or pressure concentration caused by uneven adjustment of the adjustable airbag, thus improving the effectiveness of dynamic adjustment.
[0031] Furthermore, the tension acquisition component includes a tension sensor, which is embedded within the second chest and abdominal restraint belt.
[0032] Beneficial effects: By collecting tension change data in real time through tension sensors and transmitting it to the controller, the controller can provide a quantitative basis for analyzing and evaluating the degree of agitation of the child, capture tension fluctuations when the child is agitated, ensure the timeliness and accuracy of dynamic adjustment of restraint force, and provide reliable data support for adaptive restraint.
[0033] Furthermore, elastic hand straps are fixedly connected to the outer sides of both the first and second chest and abdomen restraint straps.
[0034] Beneficial effects: The elastic wrist strap design provides a certain amount of movement space for the child's arms by utilizing the elasticity of the wrist strap. At the same time, the wrist strap can adjust the restraint space synchronously with the tightness of the chest and abdominal restraint strap, realizing the linkage adjustment between arm restraint and chest and abdominal restraint, reducing the child's resistance to restraint, avoiding discomfort caused by completely fixing the arms, and improving the overall integrity and effectiveness of restraint.
[0035] Furthermore, the wristbands are all made of knitted elastic fabric blended with polyurethane elastic fibers and combed cotton.
[0036] Beneficial effects: This design utilizes the high elasticity of polyurethane fibers and the skin-friendly breathability of combed cotton, combined with the characteristics of knitted structure, to balance restraint function and comfort. It provides moderate elastic restraint to prevent breakage, ensures skin comfort and breathability, reduces friction irritation and the risk of allergies, and is also water-resistant and disinfectable, meeting the hygiene requirements of medical environments.
[0037] Furthermore, both the first and second device housings are equipped with release buttons on their tops, and these release buttons are connected to the controller signal.
[0038] Beneficial effects: By sending a trigger signal to the controller through the release button, the controller quickly interrupts the adjustment program and drives the relevant components to release the restraints, realizing one-button emergency release. In case of sudden breathing difficulties or other emergencies, the restraints can be quickly released, buying time for rescue and avoiding the delays or secondary injuries caused by the cumbersome release of traditional devices, thus improving the safety of use.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0050] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0051] The following detailed description illustrates the specific implementation method:
[0052] Example 1:
[0053] This embodiment provides an intelligent restraint device for pediatric agitation, specifically combined with... Figure 1 and Figure 2 As shown, it includes a placement frame 1, which is placed on the surface of a regular hospital bed. A first device housing 2 and a second device housing 3 are welded to both sides of the placement frame 1. When it is necessary to restrain the child, the medical staff can lower the bed armrests and lift the placement frame 1 with both hands to slowly and steadily place the entire device on the surface of the hospital bed.
[0054] The existing circumferential chest and abdomen restraint method has advantages over the limb restraint method in terms of distributing restraint pressure, reducing the probability of escape and emotional resistance caused by the child struggling with their limbs; therefore, combined with Figure 1 and Figure 3 As shown, this embodiment is based on the ring-shaped chest and abdomen restraint method. A first chest and abdomen restraint belt 4 and a second chest and abdomen restraint belt 5 are respectively provided on the side of the first equipment shell 2 and the second equipment shell 3 that are close to each other. The first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 replace the design of one chest and abdomen restraint belt in the conventional ring-shaped chest and abdomen restraint.
[0055] Correspondingly, such as Figure 3As shown, the first chest and abdomen restraint belt 4 has two loopholes 401 (providing an orderly passage for the second chest and abdomen restraint belt 5); the second chest and abdomen restraint belt 5, after being threaded through the loopholes 401 from bottom to top, interweaves with the first chest and abdomen restraint belt 4 to form an interwoven ring-like structure around the child's chest and abdomen. The composite structure of the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 closely conforms to the physiological curves of the child's chest and abdomen, evenly distributing the restraint pressure to multiple stress areas of the chest and abdomen to avoid local pressure injuries. The first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 restrain each other to prevent a single first chest and abdomen restraint belt 4 / second chest and abdomen restraint belt 5 from shifting or loosening due to the child's struggle, achieving a stable and safe restraint effect, ensuring the effectiveness of the restraint while reducing the child's resistance and the risk of restraint-related complications. Specifically:
[0056] (1) By simulating the feeling of wrapping or hugging the agitated child, compared with the conventional limb binding restraint, it can soothe the child's agitation and reduce the fear of being bound, thus shifting from the concept of forced restraint to protective wrapping.
[0057] (2) The interlocking binding formed by the first chest and abdomen binding band 4 and the second chest and abdomen binding band 5 can transfer and disperse the force on one of the first chest and abdomen binding bands 4 / 2 chest and abdomen binding bands 5 to the other chest and abdomen binding band when the child struggles. Compared with the binding of the limbs, it can avoid the situation where the child breaks through the binding at a single point.
[0058] However, due to the different body shapes of different children, the fixed-length first and second chest and abdomen restraint belts 4 and 5 are insufficient to meet the restraint requirements. Therefore, a combination of... Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, a first tape reel assembly 6 and a second tape reel assembly 7 are respectively provided on the first device housing 2 and the second device housing 3. Both the first tape reel assembly 6 and the second tape reel assembly 7 include a tape receiving groove 8. A winding shaft 9 is rotatably connected in the tape receiving groove 8. The first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 are respectively fixedly connected to the corresponding winding shaft 9 (taking the first chest and abdomen restraint belt 4 as an example, a buckle is fused to one end of the first chest and abdomen restraint belt 4 near the tape receiving groove 8, and a fixing groove for the corresponding buckle is opened on the corresponding winding shaft 9, and the buckle is installed and fixed in the fixing groove).
[0059] Both the first device housing 2 and the second device housing 3 have drive cavities 10. Each drive cavity 10 is fixedly connected to a drive component 11 (preferably a servo motor) by bolts. The output shaft of the drive component 11 extends through the side wall of the corresponding drive cavity 10 into the tape groove 8. The output shaft of the drive component 11 is coaxially fixedly connected to the corresponding winding shaft 9. In this design, when the drive component 11 starts to rotate forward, the winding shaft 9 gradually winds the corresponding first chest and abdomen restraint belt 4 / second chest and abdomen restraint belt 5 onto the shaft surface of the winding shaft 9, shortening the effective length of the first chest and abdomen restraint belt 4 / second chest and abdomen restraint belt 5 exposed in the tape groove 8, which is suitable for children with smaller body size (such as infants) or narrower chest and abdomen circumference. When the drive component 11 rotates in reverse, the winding shaft 9 rotates counterclockwise, extending the effective length of the first chest and abdomen restraint belt 4 / second chest and abdomen restraint belt 5 exposed, which is suitable for children with larger body size (such as school-age children) or wider chest and abdomen circumference.
[0060] Although the relative chest and abdomen restraint mechanism based on the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 has achieved dynamic adjustment of the telescopic length and can adapt to the chest and abdomen circumference of different children, the vertical height difference between the chest and abdomen surface and the bed surface caused by the different physiological structure of the children may still cause potential risks such as decreased fit between the first chest and abdomen restraint belt 4 / second chest and abdomen restraint belt 5 and the child's chest and abdomen, and uneven local pressure distribution.
[0061] Based on the aforementioned deficiencies, this embodiment provides a restraint range adjustment component on both the first device housing 2 and the second device housing 3, combined with... Figure 1 and Figure 5 As shown, the restraint range adjustment components all include height adjustment grooves 12 and belt buckles 13. The belt buckles 13 are slidably engaged with the corresponding height adjustment grooves 12. The ends of the first chest and abdomen restraint belts 4 and the second chest and abdomen restraint belts 5 away from the belt grooves 8 are each welded with a belt head 14 (the belt head 14 is a T-shaped structure). The two belt heads 14 are detachably connected to the belt buckles 13 respectively. Several hanging rod grooves 15 are opened on the side of the height adjustment grooves 12 away from each other. The side of the belt buckles 13 away from the belt heads 14 is each welded with a locking rod 16. The locking rods 16 can fit and lock into the hanging rod grooves 15. Taking the adjustment of the first chest and abdomen restraint belt 4 as an example, medical staff can first determine whether it is necessary to increase or decrease the distance between the top and bottom fixing points of the first chest and abdomen restraint belt 4 based on the vertical height difference between the surface of the child's chest and abdomen and the surface of the bed. Then, the locking rod 16 is aligned and inserted into the hanging rod groove 15 of the corresponding height to complete the fitting and locking, so that the fastening buckle 13 is fixed at this height, thereby achieving precise adjustment of the distance between the top and bottom fixing points of the first chest and abdomen restraint belt 4 to adapt to the physiological structure differences of different children, improve the fit between the restraint belt and the chest and abdomen, and avoid uneven local pressure.
[0062] The special feature of this embodiment is that it considers the adjustment of dynamic restraint force based on the long-term nature of the child's agitation and the fluctuating nature of the agitation. First, this embodiment has a tension acquisition component on the second chest and abdomen restraint belt 5 for collecting the degree of the child's agitation. The tension acquisition component includes a tension sensor (not shown in the figure), which is signal-connected to a controller and is embedded in the second chest and abdomen restraint belt 5. When the relative chest and abdomen restraint constructed by the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 is formed, the tension sensor will sense the real-time tension data of the second chest and abdomen restraint belt 5. The controller receives the real-time tension data and identifies the tension changes. For example, when the child twists or struggles due to agitation, the tension on the second chest and abdomen restraint belt 5 will dynamically fluctuate with the child's movements. This dynamic fluctuation information will be identified and recorded by the controller through the tension sensor to provide mechanical data support for subsequent dynamic adjustment of the restraint force.
[0063] Secondly, combining Figure 1 and Figure 6 As shown, in this embodiment, an airbag adjustment component for adjusting the tightness of the restraint is provided on the inner side of the first chest and abdomen restraint band 4. The airbag adjustment component includes an adjustment airbag 17, which is sewn and fixed to the inner side of the first chest and abdomen restraint band 4. An air pump is embedded in the first device housing 2, which is connected to the adjustment airbag 17 and signal-connected to the controller. On the one hand, the design of the adjustment airbag 17 can evenly distribute the restraint pressure to multiple force points on the chest and abdomen by means of its flexible expansion characteristics to avoid local pressure injury and buffer the instantaneous tension fluctuations when the child is agitated to reduce the resistance of the restraint. On the other hand, the thickness and expansion state of the adjustment airbag 17 can be changed by adjusting the inflation volume of the airbag through the controller, so as to achieve the effect of dynamic restraint force adjustment.
[0064] Combining the tension changes collected by the regulating airbag 17 and the second chest and abdominal restraint belt 5, the controller receives the quantitative tension data transmitted by the tension sensor in real time. It compares this data with a preset baseline tension threshold using a built-in algorithm, and analyzes and assesses the child's agitation level based on multidimensional indicators such as the amplitude, frequency, and duration of real-time tension fluctuations (e.g., mild agitation corresponds to small, high-frequency tension fluctuations; moderate agitation corresponds to a moderate, sustained increase in tension; severe agitation corresponds to a sudden increase in tension that remains high while calmness corresponds to a flat tension). Then, based on the assessment results, it sends adjustment control commands to the pump components.
[0065] In cases of mild agitation, the inflation of the adjustable airbag 17 is slightly increased to improve the fit between the restraint strap and the chest and abdomen, reducing gaps. In cases of moderate agitation, the inflation of the adjustable airbag 17 is moderately increased to reduce the space between the first chest and abdomen restraint strap 4 and the second chest and abdomen restraint strap 5, thereby enhancing the restraint force. In cases of severe agitation, the inflation of the adjustable airbag 17 is rapidly but steadily increased to effectively restrain the child while avoiding a sudden increase in local pressure. After the child calms down, the inflation of the adjustable airbag 17 is gradually reduced to restore the child to a comfortable pre-tight state, thereby achieving dynamic adaptive adjustment of the restraint tightness.
[0066] Specifically, the coverage width of the adjustable airbag 17 is the width between the two loops 401 on the first chest and abdomen restraint belt 4. With this design, the coverage width of the adjustable airbag 17 corresponds exactly to the effective restraint area between the two loops 401 on the first chest and abdomen restraint belt 4. This design will not interfere with the process of fixing the second chest and abdomen restraint belt 5 through the loops 401 to the fastener 13. It will also ensure that when the adjustable airbag is inflated, it can achieve full and uniform pressure coverage and tightness adjustment of the effective contact area of the child's chest and abdomen. This avoids the problem of decreased fit or pressure concentration caused by uneven local adjustment of the adjustable airbag 17.
[0067] Example 2:
[0068] Based on the tension data acquisition of the second chest and abdomen binding band 5 during the binding process described in Example 1, the purpose of this example is to automatically adjust the stretching length of the first chest and abdomen binding band 4 and the second chest and abdomen binding band 5 before binding is formed:
[0069] All drive components 11 are connected to the controller via signals. After the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 are connected, the controller synchronously adjusts the signals of the two drive components 11 based on the tension data of the second chest and abdomen restraint belt 5 collected by the tension sensor. The specific signal adjustment process is as follows:
[0070] The controller first acquires several real-time tension data and compares them in real time with the preset baseline tension threshold range. The baseline tension threshold range is preset by medical staff based on clinical experience, taking into account the child's physiological characteristics (age, weight, body type, etc.) and pediatric restraint care safety standards and clinical restraint needs (such as postoperative fixation or agitation restraint). For example, a 3-year-old, 15kg postoperative calm child can be set to 10-15N to ensure fixation effect without compressing the chest and abdomen and affecting breathing, while a 5-year-old, 20kg agitated child can be set to 15-20N to balance restraint and comfort.
[0071] If the current real-time tension data is detected to be lower than the lower limit of the reference tension threshold range (indicating that the current stretching length of the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 is too long, resulting in insufficient fit with the child's chest and abdomen area), the controller immediately sends a tightening control signal to the two drive components 11 simultaneously. The two drive components 11 drive the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 to shorten until the real-time tension data is within the reference tension threshold range.
[0072] If the real-time tension data is detected to be higher than the upper limit of the reference threshold range (indicating that the current extension length of the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 is too short, resulting in excessive initial pre-tightening pressure, which may cause discomfort or local compression risk to the child), the controller will simultaneously send a relaxation control signal. The two drive components 11 will then drive the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5 to extend until the real-time tension data is within the reference tension threshold range. During this process, the controller continuously and cyclically collects the real-time tension data from the tension sensor and dynamically adjusts the output intensity and duration of the control signal to ensure that the actions of the two drive components 11 remain synchronized and precisely matched, avoiding force imbalance caused by unilateral adjustment, until the tension data is stably maintained within the reference threshold, completing the automatic adjustment of the extension length before restraint formation, and providing a safe and comfortable initial pre-tightening state for subsequent formal restraint operations.
[0073] Example 3:
[0074] As attached Figure 7 As shown, the difference from Embodiment 2 is that in this embodiment, elastic hand straps 18 are sewn and fixed to the outside of both the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5. The design of the hand straps 18, in the initial state (when the airbag 17 is not inflated), allows the child's arm to bend, extend, or rotate slightly inside the first chest and abdomen restraint belt 4 / second chest and abdomen restraint belt 5 due to the elasticity of the hand straps 18 themselves, providing a certain amount of independent movement space to reduce psychological resistance to restraint. Simultaneously, because the hand straps 18 are attached to the first chest and abdomen restraint belt 4 and the second chest and abdomen restraint belt 5... The outer side of the binding strap 4 / second chest and abdomen binding strap 5 is sewn and fixed. When the controller adjusts the inflation of the air bag 17, the effective binding area of the first chest and abdomen binding strap 4 / second chest and abdomen binding strap 5 tightens, which will cause the hand binding strap 18 to be tightened simultaneously. The elasticity of the elastic fabric increases, thereby reducing the restraint space and limiting the child's arm movement. When the air bag 17 is deflated, the loosening of the chest and abdomen binding strap will allow the hand binding strap 18 to regain its elasticity, and the restraint space will expand accordingly, realizing the synchronous restraint adjustment of the child's hands and chest and abdomen shape.
[0075] The design of this independent hand restraint is based on a wrap-around restraint system constructed from the first chest and abdomen restraint strap 4 and the second chest and abdomen restraint strap 5. In the initial state, the hand restraint strap 18 provides the child with a small range of independent hand movement space based on its own elasticity, effectively alleviating their resistance to restraint. When the child becomes agitated, the system adjusts the inflation of the airbag 17 to drive the tightening of the first chest and abdomen restraint strap 4 and the second chest and abdomen restraint strap 5, simultaneously pulling the hand restraint strap 18 towards the body (different from the adjustment method of strengthening restraint in independent limb restraint). This restraint method compresses the child's agitated activity space, reduces the points of leverage when the child is agitated, and effectively reduces the risk of escape.
[0076] The hand restraints are all made of knitted elastic fabric blended with polyurethane elastic fiber and combed cotton. The polyurethane elastic fiber has excellent elastic recovery and tensile strength, which can provide moderate restraint to prevent the child's hands from slipping out, and is not easy to break due to excessive stretching. It also maintains its elasticity for a long time without loosening, ensuring long-term stability. The blended combed cotton fiber has good moisture absorption, breathability and skin-friendliness, which can reduce friction and irritation with the child's skin, avoid skin stuffiness, redness or allergies caused by prolonged restraint, and improve the child's restraint comfort.
[0077] Example 4:
[0078] As attached Figure 1 As shown, the difference from Embodiment 3 is that both the first device housing 2 and the second device housing 3 are equipped with release buttons 19 on their tops, and the release buttons 19 are connected to the controller signal. With this design, when medical personnel or family members press any release button 19, the release button 19 immediately sends a trigger signal to the controller. Upon receiving the signal, the controller quickly interrupts the current tension adjustment program and simultaneously sends a maximum-intensity reverse release command to the drive component 11. The drive component 11 then drives and rapidly extends the effective length of the first chest and abdominal restraint belt 4 and the second chest and abdominal restraint belt 5, while simultaneously controlling the air pump adjustment. The airbag 17 is quickly deflated, causing the first and second chest and abdominal restraint straps 4 and 5 to loosen rapidly from their fitted state. At the same time, the hand restraint straps 18 also regain their elasticity as the chest and abdominal straps loosen, greatly expanding the restraint space. This allows the child's chest and abdomen to be relieved of restraint pressure, and the arms to be freely extended and moved. This design allows medical staff or family members to instantly remove the restraints without complicated operations in case of emergencies such as sudden breathing difficulties, vomiting, or choking. This buys valuable time for timely rescue and avoids the delays in treatment or secondary injuries to the child that may be caused by the cumbersome removal of traditional restraint devices.
[0079] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
