Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and more specifically, to an embracing intelligent comfort restraint seat. Background Technology

[0002] In pediatric clinical practice, children often exhibit violent crying, struggling, and physical resistance during therapeutic procedures such as injections, infusions, and blood draws due to their natural fear of medical environments and anticipation of pain. This behavior not only severely disrupts the normal operations of medical staff and reduces diagnostic and treatment efficiency, but also carries medical risks such as needle displacement, extravasation of medication, and instrument injury. Furthermore, the forced restraint process can cause significant psychological trauma to children, potentially exacerbating their "white coat phobia" and having a long-term negative impact on their future medical behavior. Therefore, to ensure the safety and smooth progress of medical procedures, the use of restraint devices for temporary, protective physical immobilization of children has become a necessary but unavoidable measure in pediatric clinical practice.

[0003] Currently, the child restraint devices used in clinical practice mainly have the following structures, but all of them have obvious defects: 1. Simple Restraint Strap Structure: This structure typically consists of multiple nylon or cotton straps. When used, it directly binds the child's chest, abdomen, wrists, ankles, etc., to an examination bed or ordinary chair. This restraint method is linear and rigid, using the straps to tighten the body to prevent movement. Its disadvantages include: small contact area, high pressure, and extremely poor comfort; the binding process is rough, easily causing panic and more intense struggle in children; and the inability to evenly distribute force, posing a safety hazard of excessive localized pressure affecting breathing or blood circulation.

[0004] 2. Rigid Restraint Board / Chair Structure: This structure is typically made of rigid plastic or metal, resembling a "small chair" with multiple fixing slots, straps, and clamps. The child is placed inside, and their head, torso, and limbs are secured by multiple rigid clamps. This restraint method uses point-like, rigid clamps. Its disadvantages include: a cold and frightening appearance, like a "torture device," which can exacerbate a child's psychological fear; a completely uncomfortable hard-surfaced surface; and the fixed points are usually not adjustable, making it unsuitable for children of different sizes and easily causing localized pressure and discomfort.

[0005] 3. Cloth-wrapped restraint structure: This structure resembles an enlarged version of a baby swaddle, using a large piece of cloth to wrap and tighten the child's entire body except for the head. This restraint method is a complete, static wrapping. Its disadvantages are: narrow applicable age range, insufficient restraint for stronger toddlers; full-body wrapping leads to poor heat dissipation and discomfort; and it cannot selectively restrain specific parts (such as only the torso), resulting in poor flexibility.

[0006] In summary, while existing child restraint devices achieve a certain degree of "restraint," their common and fundamental technical flaw lies in the fact that their restraint methods are all "passive" and static. Whether it's binding, clamping, or wrapping, they all rely on external force to "lock" the child in a fixed posture. This "forced resistance" model completely ignores the child's psychological feelings and physiological comfort. More importantly, these devices cannot provide a dynamic, immersive, and flexible restraint experience. They cannot simulate the dynamic process and sense of security of being embraced by a loved one, where force is applied evenly from both sides inwards, enveloping the body. Utility Model Content

The drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Figure 1 This is a structural schematic diagram of a preferred embodiment of the present invention: an embracing intelligent comfort restraint seat. Detailed Implementation

[0022] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0025] Furthermore, the terms indicating orientation, such as "up, down, front, back, left, right, upper end, lower end, longitudinal," etc., are all based on the posture and position of the device or equipment described in this solution during normal use.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0027] The purpose of this invention is to overcome the shortcomings of existing child restraint devices, such as being rough, rigid, and lacking in humanistic care. This embodiment provides an embracing intelligent comfort restraint seat, such as... Figure 1 As shown, the seat includes a seat back 11 and a seat body 21. The seat back 11 is used to support the child's back, and the seat body 21 is for the child to sit upright. Two first restraint modules 12 are symmetrically arranged on both sides of the seat back 11. Each first restraint module 12 includes a first connecting strap 121 with one end fixedly connected to the seat back 11. The surface of the first connecting strap 121 facing the child is provided with an inflatable first airbag 122. The free ends of the two first connecting straps 121 can be detachably connected by a first buckle assembly to simulate the mother's arms forming a restraint around the child's torso. The detachable connection of the two connecting straps by the first buckle assembly is much faster and simpler than the traditional method of binding multiple straps separately, which can effectively save the operation time of medical staff and improve the efficiency of diagnosis and treatment.

[0028] The second restraint module 22, there are two second restraint modules 22, which are symmetrically arranged on both sides of the end face of the seat body 21; each second restraint module 22 includes a second connecting strap 221 with one end fixedly connected to the seat body 21, and the surface of the second connecting strap 221 facing the child is provided with an inflatable second airbag 222. The free ends of the two second connecting straps 221 are detachably connected by a second buckle assembly to form a restraint around the child's legs; similarly, it can also provide efficiency in putting on and taking off the seat.

[0029] The first connecting strap and / or the second connecting strap are high-strength flexible webbing, which is comfortable to wear and provides a basis for the shape of the subsequent "simulated arm".

[0030] The first constraint module 12 and the second constraint module 22 can be divided into two independent modules: "torso constraint" and "leg constraint". Medical staff can selectively combine them according to different medical operations (such as only fixing the upper body for arm injection and only fixing the lower body for foot blood collection), avoiding the "one-size-fits-all" full-body constraint, which is more precise and humane.

[0031] Each of the first airbags 122 and the second airbag belts is connected to an independent pneumatic system. The intelligent comfort restraint seat also includes a control system 10, which is common in existing technologies; all pneumatic systems are electrically connected to the control system; the control system is used to control the pneumatic systems to adjust the corresponding airbags to expand or contract towards the child; after the airbags expand, the contact area is large, the pressure is small and uniform, avoiding the pain of traditional restraint straps "digging" into the skin or hard clamps "pressing" against the bones, providing extremely high comfort and being suitable for children of different sizes.

[0032] Through the above structure, the inflation and deflation of the airbag achieves a "hugging" restraint that applies force evenly from both sides inward, rather than a rough binding or clamping. This greatly improves the child's comfort and sense of security, fundamentally solving the child's psychological fear problem and giving emotional warmth to the cold medical process.

[0033] In this embodiment, both the first airbag and the second airbag are elongated structures.

[0034] Furthermore, the inner wall of the first airbag 122 and / or the second airbag 222 is provided with a pressure sensor. The pressure sensor is electrically connected to the control system and is used to monitor the pressure value exerted by the airbag on the child in real time and feed the pressure value back to the control system.

[0035] When a child struggles, their body generates tremendous impact force, potentially causing the restraint force to spike instantly, far exceeding safety thresholds. Pressure sensors immediately detect this dangerous pressure spike and relay it to the control system. Within milliseconds, the system can instruct a solenoid valve to release a small amount of pressure, quickly relieving excess pressure and preventing serious secondary injuries such as localized compression, impaired breathing, or impaired blood circulation. Even under static restraints, if the initial settings are too tight, the pressure sensors will detect persistently high pressure values. The control system will issue an audible alert to remind medical staff, allowing for correction before problems occur and nipping potential safety hazards in the bud.

[0036] Furthermore, the first and / or second buckle assembly is a magnetic buckle, including a first and second magnetic component that attract each other, and a mechanical safety buckle lock for secondary locking after magnetic attraction; the first and second magnetic components are respectively disposed on two first connecting strips or two second connecting strips; the first and second magnetic components attract each other to guide the fixing blocks at the free ends of the two first connecting strips or two second connecting strips to automatically align and pre-tighten. In this embodiment, the mechanical safety lock can adopt a lock hole structure in the prior art, similar to the seat belt buckle structure in a vehicle, such as including a pressable locking button and a locking tongue linked thereto; the locking button and the locking tongue are respectively disposed on the fixing blocks at the free ends of the two first connecting strips or two second connecting strips; after magnetic pre-tightening, pressing the locking button causes the locking tongue to engage with the locking groove disposed on another connecting strip, thereby achieving secondary mechanical locking to prevent accidental opening; this composite buckle design of "magnetic attraction + mechanical safety lock" brings multiple benefits in terms of ease of operation, safety and reliability, and user experience.

[0037] During connection, medical staff simply bring the free ends of the two connecting straps roughly together, and the magnets will automatically attract and align them in the correct position. This completely eliminates the cumbersome operation of precise alignment required by traditional buckles (such as snaps and hooks). This convenience of "blind operation" is especially important when holding a crying or struggling child, reducing restraint time by several seconds, which is significant in emergency situations. Due to the automatic positioning function of the magnetic attraction, medical staff can easily complete the connection of both ends while continuing to soothe the child or perform other operations with their other hand, greatly improving the flexibility and efficiency of clinical procedures.

[0038] When a mechanical safety lock is successfully engaged, it is usually accompanied by a crisp "click" sound and / or a distinct tactile feedback. This signal tells healthcare workers, "The lock is engaged; it is safe now." This tactile and auditory confirmation avoids repeated checks due to concerns about proper engagement and prevents safety incidents caused by "false locks."

[0039] Furthermore, the pneumatic system includes a miniature air pump 123 and a solenoid valve 124 as in the prior art. The miniature air pump 123 serves as the air source and is connected to the corresponding airbag via an air tube 125. The control system selectively introduces compressed air generated by the miniature air pump 123 into the airbag for inflation or deflates the airbag by controlling the valve position switching of the solenoid valve 124. Preferably, the miniature air pump is a low-noise diaphragm pump to reduce disturbance to children during operation.

[0040] It is thanks to the air pump and solenoid valve that the airbag can achieve "slow inflation" and "controlled deflation." This makes restraint no longer an instantaneous, abrupt action, but a gradual, perceptible process. This slow tightening process perfectly simulates the dynamic rhythm of a mother's embrace, giving children time to psychologically adapt, and is the physical basis of the "soft restraint" concept.

[0041] Furthermore, the support surfaces of the seat back 11 and / or seat body 21 are filled with rebound memory foam, which is slow-rebound memory foam with a slow rebound characteristic in the prior art. The slow-rebound memory foam is integrally molded into a block-shaped filler that matches the contour of the support surfaces of the seat back 11 and seat body 21. In one embodiment, the filler has a smooth outer surface, and its thickness varies according to the needs of different support areas, for example, the thickness is greater in the lumbar and hip areas than in other areas; or, the surface of the rebound memory foam is shaped into an S-shaped or C-shaped contour that conforms to the natural physiological curve of a child's spine, and forms a forward-protruding support flange in the lumbar region to provide strong support for the child's lower back and maintain a healthy sitting posture.

[0042] In another embodiment, the frame of the seat back 11 is also provided with an intelligent soothing system electrically connected to the control system; the intelligent soothing system includes a somatosensory simulation module for simulating the vibration of a mother's heartbeat rhythm and an auditory simulation module for playing audio simulating a mother's gentle humming.

[0043] In this embodiment, the motion simulation module can be an eccentric wheel motor, which is the most common, lowest-cost, and most mature vibration solution in the prior art. It includes a DC brushed motor with an eccentric metal block (such as a counterweight) mounted on the motor's output shaft. It also includes a simple drive circuit (such as an H-bridge or transistor switch) to control the motor's start / stop and speed. When the motor is powered on and rotates, the eccentric block on the shaft rotates at high speed, generating a centrifugal force. The direction of this centrifugal force changes continuously as the motor rotates, causing the entire motor module to vibrate. By controlling the motor's speed, the vibration frequency can be changed; by controlling the motor's energizing time, the "pulsating" pattern of a heartbeat can be simulated (e.g., on-off-on, simulating a "thump-thump" rhythm).

[0044] The motion simulation module can utilize a linear resonant actuator (LRA), a type of vibration motor widely used in modern smartphones, to provide a more precise and nuanced vibration experience. It typically includes a sealed assembly containing a spring, magnet, and coil, along with a dedicated driver IC (integrated circuit) to generate an alternating current signal at a specific frequency. By supplying the coil with this AC signal through the driver IC, a changing magnetic field is created. This magnetic field interacts with a permanent magnet, driving the spring-mass system to reciprocate at its natural resonant frequency, producing a very clear and short linear vibration. To simulate a heartbeat, the driver IC outputs a short pulse signal, driving the LRA to produce a "click"-like vibration, then stopping and waiting for the next pulse. This vibration is highly precise and nuanced, simulating a very realistic "knocking" sensation of a heartbeat.

[0045] In this embodiment, the auditory simulation module is existing technology, including at least one speaker and an audio storage unit electrically connected to the speaker. The audio storage unit pre-stores white noise, lullabies, or recordings of the mother, which can greatly alleviate the child's psychological distress. The mother's or a relative's voice can be pre-recorded before use. The speakers are located on both sides of the headrest area of ​​the seat back 11, used to play the content stored in the audio storage unit to the child.

[0046] Furthermore, the intelligent soothing system also includes a visual interaction module 31 that is electrically connected to and controlled by the control system; the visual interaction module 31 includes an LED ambient light strip 311 disposed on the outer periphery of the seat body 21 or in the armrest area, and an interactive button module 312 for children to press to change the color or flashing mode of the LED ambient light strip 311; it is worth noting that the connection method and control method between the LED ambient light strip 311 and the interactive button module 312 are common technical means in the field of lighting, and will not be described in detail here.

[0047] Vision is the primary channel for human information reception, especially for children, for whom bright, dynamic light is extremely attractive. The gentle changes in the LED ambient light strip 311 create an engaging visual focus for children. When children are focused on "what color the light will turn next," their brains' perception of ongoing or upcoming medical procedures (such as injections or blood draws) is significantly reduced. This, to some extent, serves as a form of cognitive distraction and even pain relief.

[0048] Healthcare professionals can guide children, for example, by saying, "Let's play a color-changing game. Press the button and see what happens!" This interaction cleverly transforms the originally cold and serious medical process into a lighthearted and fun game, greatly improving children's cooperation. It shifts children's attention from "pain" to "fun," and from "passive acceptance" to "active creation." This not only greatly enhances the experience and efficiency of each treatment session but also subtly helps children develop a positive perception of the medical environment, demonstrating exceptional technological ingenuity and humanistic care.

[0049] Through multi-sensory synergy, fear can be alleviated to the greatest extent. Children can hear a "thump-thump" sound similar to a mother's heartbeat or soft humming, feel synchronized, rhythmic, slight vibrations, experience the physical sensation of being hugged, and have their vision redirected. This synergistic effect of auditory, physical, and visual sensations provides the child's brain with a strong and credible signal; heartbeat and humming are two of the most primal and profound soothing signals a mother gives to her fetus and infant. This system precisely replicates these two instinctive soothing behaviors through technological means. It is not simply "playing music," but rather simulating "the mother's presence," which has a powerful soothing effect in psychology and can effectively fill the emotional void in children in unfamiliar medical environments.

[0050] When a child stops struggling violently, healthcare professionals can perform more precise and stable procedures (such as intravenous punctures). This significantly improves the success rate of injections and blood draws, reducing the additional pain and trauma caused to the child by repeated attempts. It also saves healthcare professionals time and energy: they no longer need to spend considerable time and effort soothing and suppressing a crying child, nor do they need to deal with the anxiety of parents seeing their child in pain. The entire treatment process becomes smoother, improving efficiency per unit of time.

[0051] Furthermore, an angle adjustment component 41 is provided between the seat backrest 11 and the seat body 21; the seat backrest 11 can rotate relative to the seat body 21 via the angle adjustment component 41. The physiological structures of newborns, toddlers, and school-aged children differ greatly. The angle adjustment function allows the same seat to provide a suitable and supportive position for children of different ages by adjusting the backrest angle. For example, newborns need a more supine position, while older children can sit comfortably. This greatly expands the applicability and cost-effectiveness of the device.

[0052] When performing procedures such as chest auscultation and abdominal palpation, tilting the backrest back appropriately provides medical staff with a wider field of vision and more ample operating space, which helps improve the accuracy of the examination and the efficiency of the operation, and reduces additional discomfort to children caused by inconvenience in operation. This angle adjustment component can be a rotating component commonly found in car seats, beach chairs, and folding chairs in the prior art, including a gear disk (or adjustment disk) fixed to the seat body 21; a locking pawl (or ratchet) that meshes with the gear disk and is fixed to the pivot of the seat back 11; an adjustment wrench for controlling the engagement and disengagement of the pawl; and a return spring for pressing the pawl against the gear disk to maintain the locked state.

[0053] Move the adjusting lever to disengage the pawl from the gear plate, allowing the backrest to rotate. When the desired angle is reached, release the lever; the return spring pushes the pawl back into the gear plate's grooves, locking it in place. This design typically features stepped adjustment, for example, in 15-degree or 30-degree increments.

[0054] Alternatively, in another embodiment, the seat backrest 11 is integrally formed with the seat body 21; the seat backrest 11 conforms to the natural spinal curve of a child, providing strong lumbar support; the hip support area of ​​the seat body 21 is concave and bowl-shaped to stably wrap around the child's hips. This design allows the support curve to extend continuously and naturally, providing the child with the most body-fitting support.

[0055] In this invention, the "inflatable hug restraint" mode is the core function. Its working principle is a closed-loop intelligent process that integrates physical restraint, physiological feedback, and psychological comfort. The specific working principle is as follows: 1. Preparation and donning stage: Medical staff place the child in the seat. First, the first connecting straps 121 on both sides of the seat are wrapped around the child's torso, with their free ends quickly connected in front of the chest via the first buckle assembly (such as a magnetic buckle), forming a loose, uninflated loop. Similarly, the second connecting strap 221 can be wrapped around the child's thighs and connected via the second buckle assembly.

[0056] Initial state: All first airbags 122 and second airbags 222 are in the deflated state, and the connecting straps are softly attached to the child's body, with almost no restraint, avoiding tension during the initial installation.

[0057] 2. Start-up and intelligent inflation phase: Healthcare workers can select the "Embrace Restraint" mode through a control system (such as a touch control computer in existing technology) and can set a preset pressure value or select a specific scenario program (such as "Injection Mode").

[0058] The control system sends commands to the corresponding pneumatic systems (miniature air pumps and solenoid valves). The miniature air pumps then begin to slowly and evenly inflate their corresponding air bags through the air tubes.

[0059] During inflation, as the airbag expands, the connecting straps slowly tighten inwards from both sides, extending the contact area from lines to surfaces, evenly wrapping around the child's torso and / or legs. This process simulates the dynamic process of a mother opening her arms and then slowly tightening them in a hug, giving the child an adaptation period rather than an instantaneous shock.

[0060] 3. Intelligent Feedback and Stability Constraint Stage: During inflation, pressure sensors installed on the inner wall of the airbag monitor the pressure applied to the child's body in real time and continuously feed the data back to the control system. When the pressure reaches the preset safety threshold, the control system immediately instructs the solenoid valve to close, stopping inflation. If a child struggles during restraint, causing a sudden increase in pressure, the sensor will detect this change, and the control system will instruct the solenoid valve to release a small amount of air, restoring the pressure to a safe range. Conversely, if there is a slight leak in the airbag causing a pressure drop, the system will automatically replenish the air. This forms a smart closed loop of "monitoring-feedback-adjustment," ensuring that the restraint force remains constant within a safe and effective range.

[0061] While the child is restrained and stabilized, the intelligent soothing system is activated. The somatosensory simulation module generates slight vibrations synchronized with the heartbeat frequency, the auditory simulation module plays lullabies or recordings of the mother, and the LED strip of the visual interaction module flashes softly. These soothing signals, synchronized with the physical restraints, work together to maximize the diversion of the child's attention and alleviate their fear.

[0062] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
