Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a stabilizer for the orbital environment in cases of eye perforation. Background Technology

[0002] Perforated eye injuries are among the most critical and severe ophthalmic conditions, typically caused by direct penetration of a sharp object or impact from a high-speed foreign object. These injuries result in a full-thickness rupture of the eyeball wall, directly exposing the anterior chamber and vitreous cavity to the outside, causing rapid leakage of aqueous humor and a sudden collapse in intraocular pressure. When normal intraocular pressure cannot be maintained, intraocular tissues such as the vitreous body, retina, and even the choroid can prolapse through the wound, causing irreversible and severe visual impairment and significantly increasing the risk of intraocular infection. In the clinical treatment of such injuries, the transfer process from the accident scene to the specialized operating room is a critical window affecting the final prognosis, but this period presents several interconnected and serious challenges.

[0003] Currently, the standard treatment for perforated eye injuries in pre-hospital emergency care and transport typically involves only simple covering with sterile gauze or a metal eye shield. However, this passive protective measure has fundamental limitations. Gauze covering cannot create an effective airtight environment; atmospheric pressure acts directly on the exposed wound, easily accelerating the leakage of intraocular contents. Research data shows that when intraocular pressure remains below 5 mmHg during transport, the leakage of intraocular contents is highly accelerated. While metal eye shields can withstand external impacts, their rigid structure directly transmits low-frequency vibrations (3-15 Hz) generated during vehicle transport to the orbit, causing eyeball displacement of up to 1.2 mm, thus exacerbating wound tearing. Simultaneously, the open wound provides a pathway for bacterial invasion, and the inability to maintain a sterile environment during transport significantly increases the incidence of postoperative endophthalmitis. Furthermore, no existing protective device can perform emergency drug administration while maintaining wound sealing. Any attempt to instill antibiotics or maintain intraocular pressure requires removing the covering, instantly disrupting the fragile wound environment and creating a dilemma between infection control and tissue protection.

[0004] In summary, existing technologies for transporting patients with perforated eye injuries suffer from several key shortcomings. These include the inability to maintain physiological intraocular pressure, the inability to effectively isolate infection, the inability to buffer harmful mechanical vibrations, and the inability to perform emergency procedures without compromising the seal. These shortcomings directly lead to a high incidence of secondary injuries and poor prognosis after primary surgery. Therefore, clinical practice urgently requires a comprehensive transport device that integrates sealing, pressure stabilization, shock absorption, and therapeutic functions to fill the critical technological gap in the current emergency care chain, buy precious treatment time for patients, and preserve visual function to the greatest extent possible. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose an intraorbital environment stabilizer for ocular perforation injuries. This stabilizer is achieved by a comprehensive protective system consisting of an adaptive sealing base with a biomimetic adsorption structure and an inflatable sealing ring, a rigid transparent outer cover connected by a universal shock-absorbing bracket, a micro-positive pressure maintenance system integrating a mechanical pressure self-regulating unit, an ocular stabilization system with a built-in shape memory alloy elastic support arm, and a sterile drug delivery interface with a dual-channel design. This system addresses key issues in existing technologies, such as the inability to effectively maintain intraocular pressure during transport, leading to leakage of intraocular contents; the lack of shock absorption and ocular displacement control mechanisms, exacerbating tissue damage; insufficient sealing reliability causing secondary infections; and the inability to perform emergency drug delivery in a closed environment.

[0006] This invention is achieved through the following technical solution:

[0007] An orbital environment stabilizer for eye perforation injuries includes an adaptive sealing base, a rigid transparent outer cover, a universal shock-absorbing bracket, a micro-positive pressure maintenance system, a sterile drug delivery interface, an eye stabilization system, and a double sealing mechanism. The adaptive sealing base is located at the bottom of the device and conforms to the patient's orbital contour. An operation hole is located in the center of the adaptive sealing base, and a biomimetic adsorption structure is provided at the edge of the adaptive sealing base. The double sealing mechanism includes an inflatable sealing ring and a magnetic latch. The inflatable sealing ring is disposed inside the edge of the adaptive sealing base. The rigid transparent outer cover is located above the adaptive sealing base and is detachably connected to the adaptive sealing base via the magnetic latch. The rigid transparent outer cover and the adaptive sealing base together form a sealed cavity. The universal shock-absorbing bracket includes multiple sets of spring-damping composite units, which are circumferentially distributed. The upper end of a set of spring-damping composite units is fixedly connected to the bottom edge of the rigid transparent outer cover, and the lower end of each set of spring-damping composite units is fixedly connected to the edge of the adaptive sealing base. The micro-positive pressure maintenance system is integrated on the top of the rigid transparent outer cover. The micro-positive pressure maintenance system includes an air pump, a mechanical pressure valve, and an air filter. The air pump is connected to the rigid transparent outer cover through a pipeline. The mechanical pressure valve is located on the pipeline, and the air filter is located at the air inlet of the air pump. The sterile drug delivery interface is located on the top of the rigid transparent outer cover, and the sterile drug delivery interface has a built-in self-sealing diaphragm. The eyeball stabilization system includes an adjustable contact ring and an elastic support arm. The upper end of the elastic support arm is fixedly connected to the inner wall of the rigid transparent outer cover, and the lower end of the elastic support arm is connected to the adjustable contact ring. The adjustable contact ring is located inside the sealed cavity and is used to gently press against the surface of the eyeball.

[0008] Furthermore, the magnetic latch includes an annular permanent magnet array and a corresponding iron alloy ring. The annular permanent magnet array is embedded around the operating hole of the adaptive sealing base, and the iron alloy ring is fixed to the bottom edge of the rigid transparent outer cover.

[0009] Furthermore, the spring-damping composite unit of the universal shock absorber bracket includes a low-stiffness conical compression spring and a damping silicone column, wherein the damping silicone column is coaxially filled inside the low-stiffness conical compression spring; the universal shock absorber bracket also includes an axial limiting ring, which is sleeved on the outside of the spring-damping composite unit.

[0010] Furthermore, the air filter of the micro-positive pressure maintenance system is a HEPA-grade filter element; the micro-positive pressure maintenance system also includes a mechanical pressure self-regulating unit, which includes a lever counterweight mechanism and a slide valve. The lever counterweight mechanism is located on the top of the rigid transparent outer cover, and the slide valve is connected to the lever counterweight mechanism.

[0011] Furthermore, it also includes quick-fixing straps, which are connected to both sides of the adaptive sealing base via buckles.

[0012] Furthermore, the top of the rigid transparent outer cover is provided with a pressure monitoring window, and the pressure monitoring window has a built-in mechanical pressure gauge.

[0013] Furthermore, the biomimetic adsorption structure of the adaptive sealing base is a micron-scale array of suction cups, and the opening direction of the micron-scale array of suction cups is tilted towards the center of the operating hole.

[0014] Furthermore, the aseptic drug delivery interface includes a main drug delivery channel and an auxiliary drainage channel. The main drug delivery channel has a built-in self-sealing diaphragm, and the auxiliary drainage channel has a built-in one-way duckbill valve.

[0015] Furthermore, the adjustable contact ring of the eye stabilization system is made of porous silicone, and the adjustable contact ring is connected to the elastic support arm through a threaded adjustment mechanism; the elastic support arm is made of shape memory alloy.

[0016] Furthermore, the inflatable sealing ring of the dual sealing mechanism is made of elastic latex tubing.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention employs a comprehensive protective device that integrates a dynamic sealing structure, a universal shock-absorbing support, and a micro-positive pressure maintenance system. A dual-sealing mechanism, consisting of an inflatable sealing ring for the face and a magnetically locked instrument seal, effectively establishes a completely sealed cavity isolated from the external environment, significantly reducing the risk of secondary infection. The synergistic protective system, comprised of a universal shock-absorbing support and an active eye stabilization system, simultaneously buffers externally transmitted mechanical vibrations and inhibits eyeball displacement, fundamentally preventing secondary tissue damage caused by vibration during transport. The micro-positive pressure maintenance system, integrating a mechanical pressure self-regulating unit, continuously provides a stable physiological pressure environment for the injured eye, counteracting atmospheric pressure to prevent leakage of intraocular contents while avoiding excessive pressure damage to the eyeball. Equipped with a dual-channel sterile drug delivery interface, it enables emergency drug administration and exudate drainage without compressing the seal, greatly facilitating medical procedures during transport. Through the coordinated operation of all systems, this device creates a safe, sealed, and stable temporary physiological environment for patients with perforated eye injuries, significantly improving transport success rates and subsequent surgical outcomes.

[0027] like Figures 1 to 6 As shown, this embodiment provides an intraorbital environment stabilizer for ocular perforation injuries, comprising an adaptive sealing base 1, a rigid transparent outer cover 7, and a universal shock-absorbing bracket 11 connecting the two, which together form a basic frame. A micro-positive pressure maintenance system, a sterile drug delivery interface 24, an ocular stabilization system, and a double sealing mechanism 30 are precisely integrated as functional modules within this frame.

[0028] The adaptive sealing base 1, as the basic component that comes into direct contact with the patient's face, functions similarly to the "foundation" of a building. Through the flexibility of its material and its special surface structure, it achieves an initial seal against the irregular contours of the eye socket. The rigid transparent outer cover 7 acts like a sturdy "dome," working together with the adaptive sealing base 1 to create a sealed cavity for containing and protecting the injured eye. The omnidirectional shock-absorbing bracket 11 acts like an "elastic support group" connecting the foundation and the dome. It is not a rigid connection, but rather, through its unique mechanical structure, it allows relative displacement between the outer cover and the adaptive sealing base 1 within a certain range, thereby absorbing and dissipating external vibration energy and preventing it from being directly transmitted to the eyeball.

[0029] More importantly, the eye stabilization system extends downwards from the inner top wall of the rigid transparent outer casing 7, its end gently contacting the surface of the eyeball to form an internal stabilizing anchor point. This works in conjunction with the universal shock-absorbing bracket 11 to constitute a displacement control system that provides both internal and external protection. The dual sealing mechanism 30 further enhances the sealing reliability between the adaptive sealing base 1 and the skin, as well as between the adaptive sealing base 1 and the outer casing, ensuring the stability of the internal micro-positive pressure environment. The micro-positive pressure maintenance system continuously delivers clean air into the sealed cavity and precisely regulates the pressure. The sterile drug delivery interface 24 allows for emergency drug administration or drainage without compromising the seal.

[0030] The adaptive sealing base 1 is the interface between this device and the human body, directly determining the reliability of the initial seal and the patient's comfort. This adaptive sealing base 1 is made of medical-grade silicone through integral injection molding, and its material properties combine flexibility, biocompatibility, and appropriate viscoelasticity.

[0031] The adaptive sealing base 1 is an irregularly shaped ring structure that conforms to the contour of the human eye socket. In the center of the adaptive sealing base 1, there is an operation hole 2. When the device is first worn, the operation hole 2 provides medical staff with an operating space to directly perform emergency treatment on the eyeball wound (such as instilling antibiotic eye drops) without waiting for the entire device to be completely sealed.

[0032] Surrounding the periphery of the operating hole 2, a ring-shaped permanent magnet array 3, composed of multiple independent neodymium iron boron magnets, is precisely embedded. These magnets are arranged in an alternating polarity manner to generate the strongest magnetic attraction circuit. This ring-shaped permanent magnet array 3 is an important component of the magnetic latch, responsible for generating a strong attraction force with the iron alloy ring 8 on the rigid transparent outer cover 7.

[0033] On the lower surface of the adaptive sealing base 1 facing the facial skin, a precise biomimetic adsorption structure 4 is molded along its edge. The biomimetic adsorption structure 4 is a micron-scale array of suction cups, composed of several micro-suction cups. The opening direction of each micro-suction cup has been calibrated and adjusted, and the tilt angle of the micro-suction cup points towards the center of the operating hole 2. When the adaptive sealing base 1 is pressed onto clean skin around the eye socket, these micro-suction cups effectively expel some air, using atmospheric pressure to generate adsorption force, forming a preliminary and reliable primary seal. This design is particularly suitable for skin surfaces that may be moist due to sweat or slight exudate.

[0034] As a key component of the dual-sealing mechanism 30, a hollow, inflatable sealing ring 31 made of highly elastic latex material is pre-embedded inside the edge of the adaptive sealing base 1, adjacent to the inner side of the biomimetic adsorption structure 4. The inflatable sealing ring 31 is initially flat and uninflated to avoid affecting the initial fit of the adaptive sealing base 1. A miniature inflation port 5 with an electromagnetic valve is located on the side edge of the adaptive sealing base 1 and connected to the inflatable sealing ring 31 via a thin internal tube. After the adaptive sealing base 1 is initially fixed, medical personnel can use the included manual balloon pump connected to the inflation port 5 to inject a small amount of air into the inflatable sealing ring 31. As the inflatable sealing ring 31 inflates, it acts like a flexible dam, tightly pressing against the skin surface and filling tiny gaps caused by facial contours or hair, thus forming a strong, adaptive secondary seal. This dual-sealing design greatly enhances adaptability to different facial anatomy structures and fundamentally reduces the risk of leakage.

[0035] On the upper edge of the adaptive sealing base 1, an annular groove 6 is also machined around the adaptive sealing base 1. The annular groove 6 is used to fix the lower end of the universal shock absorber bracket 11.

[0036] The rigid transparent outer cover 7 is a key component of the sealed cavity. It is made of polycarbonate material with high light transmittance and high impact resistance. After CNC machining and polishing, it forms an observation window with excellent optical performance, which makes it easy for medical staff to observe the condition of the injured eye at any time during transportation.

[0037] The rigid transparent outer cover 7 is hemispherical in shape, with its bottom edge precision-machined to form an iron alloy ring 8 that precisely corresponds to the position of the annular permanent magnet array 3 on the adaptive sealing base 1. The iron alloy ring 8 and the annular permanent magnet array 3 together form a complete magnetic latch. When the rigid transparent outer cover 7 aligns with and closes to the adaptive sealing base 1, the strong magnetic force provided by the magnetic latch causes the rigid transparent outer cover 7 and the adaptive sealing base 1 to instantly adhere, stick together, and lock. This connection method is fast, reliable, and requires no complex alignment operations, making it crucial in emergency situations.

[0038] At the top of the dome of the rigid transparent outer casing 7, there is a multi-functional integrated interface block. This multi-functional integrated interface block uses a T-junction design and integrates several key functional components:

[0039] The air intake interface of the micro-positive pressure maintenance system is located on the left side of the multi-functional integrated interface block. The air intake interface is connected to the external miniature diaphragm air pump 17 via a flexible medical-grade tubing. The miniature diaphragm air pump 17 is fixed to the outer wall of the rigid transparent outer casing 7 via a specially designed mounting bracket, which saves space and avoids tubing entanglement.

[0040] On the right side of the multi-functional integrated interface block, there is a circular pressure monitoring window 9. A mechanical pressure gauge 18 is installed inside the pressure monitoring window 9. The pointer of the mechanical pressure gauge 18 directly indicates the real-time pressure value within the sealed cavity. The range of the mechanical pressure gauge 18 is specially calibrated to precisely cover the range of 0 to 50 mmHg, ensuring that the target pressure range of 20-25 mmHg can be clearly and accurately read.

[0041] At the center of the multi-functional integrated interface block, a sterile drug delivery interface 24 is vertically mounted. The sterile drug delivery interface 24 adopts an innovative dual-channel design: the main drug delivery channel is a standard Luer connector with a self-sealing diaphragm 25 embedded inside; next to the main drug delivery channel is a smaller diameter auxiliary drainage channel 26, which integrates a one-way duckbill valve.

[0042] Furthermore, on the inner wall of the rigid transparent outer casing 7, in the transition area between the dome and the straight wall, a connecting plate is provided. Three mounting seats 10 with internal threads are machined at 120-degree equidistant angles on the lower end face of the connecting plate. These three mounting seats 10 are the fixing points of the eyeball stabilization system above, used to connect and fix the ball joint of the elastic support arm 29.

[0043] The universal shock absorber bracket 11 is the core component for solving the problems of low-frequency vibration and high-frequency shaking during transportation. It is not a single component, but rather consists of six identical spring-damping composite units 12, evenly distributed in a circle, connected between the adaptive sealing base 1 and the rigid transparent outer cover 7.

[0044] Each set of spring-damping composite units 12 is an independent shock absorber. Its core is a low-stiffness conical compression spring 13. When compressed, the stiffness of this conical compression spring 13 increases non-linearly with the increase of the compression stroke, thus providing a "soft at first, hard later" buffering characteristic, effectively absorbing small vibrations while coping with larger impacts. A cylindrical damping silicone column 14 is coaxially filled in the internal cavity of the conical compression spring 13. The damping silicone column 14 maintains close contact with the inner wall of the conical compression spring 13 but is not rigidly connected.

[0045] The upper end of each spring-damping composite unit 12 is screwed into a corresponding threaded hole machined on the bottom edge of the connecting plate via a connector with external threads. The lower end of the spring-damping composite unit 12 is engaged in a specially designed annular groove 6 on the upper edge of the adaptive sealing base 1 via a ball-head rotating seat, and the ball-head rotating seat can rotate freely within the annular groove 6. This connection method of "rigidly fixed at the upper end and allowing a certain degree of swing at the lower end" gives the entire support system multi-directional displacement freedom, that is, "omnidirectional" vibration damping capability.

[0046] When external vibrations are transmitted through the adaptive sealing base 1, the conical compression spring 13 first undergoes elastic deformation, absorbing and storing most of the vibration energy. Simultaneously, the internal damping silicone pillar 14 undergoes significant viscoelastic shear deformation, converting the energy stored in the conical compression spring 13, as well as some of the direct kinetic energy, into heat energy and dissipating it. The conical compression spring 13 is primarily responsible for handling low-frequency, large-displacement vibrations, while the damping silicone pillar 14 excels at suppressing high-frequency, small-amplitude vibrations. The combination of these two elements achieves efficient attenuation of broadband vibration energy.

[0047] To prevent the rigid transparent outer cover 7 from rigidly colliding with the adaptive sealing base 1 due to excessive compression of the spring-damping composite unit 12 under extreme impact, an axial limiting ring 15 is fitted around the outside of each spring-damping composite unit 12. This axial limiting ring 15 is a rigid sleeve designed to ensure that when the compression stroke of the universal shock absorber bracket 11 reaches its safe limit, both ends of the axial limiting ring 15 abut against the corresponding connecting plate of the rigid transparent outer cover 7 and the annular groove 6 on the adaptive sealing base 1, respectively, thus limiting the compression stroke within a safe range and ensuring sufficient buffer space for the eyeball under any circumstances.

[0048] The task of a micropositive pressure maintenance system is to create and maintain a stable internal environment that is higher than atmospheric pressure but lower than normal intraocular pressure. The system consists of four subsystems: gas source, filtration, regulation, and monitoring.

[0049] The air source is provided by a miniature diaphragm air pump 17, and the air outlet of the miniature diaphragm air pump 17 is connected to a HEPA-grade air filter 19 through a pipeline to ensure that the air entering the cavity is sterile and dust-free. After being filtered and cleaned, the gas enters the sealed cavity through the air inlet located at the top of the rigid transparent outer cover 7.

[0050] The control is accomplished by two parallel, purely mechanical components. The first is a mechanical pressure valve 20, which is installed inside the air inlet. Inside the mechanical pressure valve 20 is a sensitive pressure feedback diaphragm. When the pressure inside the chamber exceeds a preset value, the pressure feedback diaphragm deforms against the preload of the internal spring, pushing the valve core to close the air inlet passage; it then waits for the mechanical pressure self-regulating unit 21 to release pressure. When the pressure drops, the pressure feedback diaphragm resets, and the valve closes. It is responsible for the routine dynamic pressure balance.

[0051] The second feature is the mechanical pressure self-regulating unit 21, unique to this embodiment. This unit acts as a safety backup and precision adjustment device, working in conjunction with the mechanical pressure valve 20. The mechanical pressure self-regulating unit 21 includes a precision lever counterweight mechanism 22 and a slide valve 23. One end of the lever counterweight mechanism 22 is an adjustable counterweight whose mass is set to achieve perfect balance under a pressure of 25 mmHg. The other end of the lever counterweight mechanism 22 abuts against the valve stem of the slide valve 23. Within the normal pressure range, the lever counterweight mechanism 22 remains balanced, and the slide valve 23 is closed. If, for any reason, the pressure inside the chamber exceeds 25 mmHg, the force acting on the lever sensing diaphragm will exceed the torque of the counterweight, causing the lever counterweight mechanism 22 to tilt. This tilts the valve stem of the slide valve 23, opening a pressure relief channel and quickly releasing excess pressure. When the pressure returns to the safe value of 25 mmHg, the lever counterweight mechanism 22 resets under the action of the counterweight, and the slide valve 23 closes. This purely mechanical feedback control, which does not rely on any electricity, is extremely reliable and ensures the accuracy and safety of pressure control.

[0052] Monitoring is achieved through the aforementioned mechanical pressure gauge 18, providing medical staff with intuitive and continuous pressure readings.

[0053] The eye stabilization system is a structure that actively prevents the eyeball from moving within the cavity. It consists of an adjustable contact ring 28 and three elastic support arms 29.

[0054] The upper ends of the three flexible support arms 29 are connected to three mounting seats 10 inside the rigid transparent outer cover 7 via ball joints. This ball joint connection allows the flexible support arms 29 to swing freely within a certain conical angle to accommodate the eyeball protrusion and relative position of different patients.

[0055] The elastic support arm 29 is made of a biocompatible shape memory alloy (such as nitinol). This alloy undergoes special treatment, with the austenitic phase transformation completion temperature set between 34-36°C, slightly lower than or equal to the normal human body surface temperature. When the device is worn on the eye, under the influence of body temperature, the elastic support arm 29 completely transforms into an austenitic state, restoring its preset shape that gently conforms to the curvature of the eyeball's equator. This "body temperature driven" characteristic allows the elastic support arm 29 to automatically and gently deliver and rest the adjustable contact ring 28 at its end onto the surface of the eyeball without any external power or manual adjustment.

[0056] The adjustable contact ring 28 is itself a ring made of porous medical-grade silicone. The inner diameter of the adjustable contact ring 28 can be finely adjusted via a precision annular thread mechanism to accommodate different eyeball sizes. The portion of the ring that contacts the eyeball is designed to be wide and flexible, ensuring maximum contact area and minimizing pressure (typically less than 2 mmHg). The porous structure of the adjustable contact ring 28 ensures that it does not isolate the eyeball surface, allowing tears or medications to pass freely, achieving a "stable but not isolated" treatment environment. This eye stabilization system effectively restricts the translation and rotation of the eyeball in the horizontal and sagittal planes, perfectly complementing the omnidirectional shock absorber 11's external vibration isolation. It also prevents the eyeball from protruding upwards from the eye socket due to violent up-and-down shaking when the patient is lying flat in an ambulance or hospital bed.

[0057] The aseptic drug delivery interface 24 is designed to achieve seamless integration of treatment procedures. The self-sealing diaphragm 25 within the main drug delivery channel of the aseptic drug delivery interface 24 is made of highly elastic medical-grade silicone. When drug delivery is required, the self-sealing diaphragm 25 can be easily punctured with a standard syringe needle for injection. Upon needle withdrawal, the elastic recovery force of the silicone material causes the puncture hole to close instantly, forming an effective seal and preventing pressure leakage.

[0058] The auxiliary drainage channel 26 contains a one-way duckbill valve, with its valve opening located at the bottom of the channel. Made of transparent material, this valve is normally closed, isolating the internal and external environments. When excessive fluid reaches the valve opening due to wound exudation or medication accumulation within the sealed cavity, the static pressure of the fluid forces the valve open, allowing excess fluid to flow through a connected thin tube into an auxiliary reservoir bag. This reservoir bag is equipped with a negative pressure adsorption structure to help remove the fluid that came into contact with the open valve. Once the pressure from the accumulated fluid is released, the one-way duckbill valve automatically springs back and closes, resealing the area. This design solves the problem of pressure buildup or secondary infection caused by excessive internal fluid accumulation during prolonged transport with traditional goggles.

[0059] To further enhance the overall stability of the device under severe turbulence, this device is also equipped with a quick-release strap 32. This quick-release strap 32 is connected to both sides of the self-adaptive sealing base 1 via two quick-release buckles 33. The strap is made of a composite elastic webbing with hook and loop sides, allowing for easy wrapping around the patient's head and quick, precise adjustment and fixation according to head circumference, providing an additional, reliable mechanical anchor point for the entire device.

[0060] In this embodiment, during the initial emergency treatment phase, medical personnel first clean the skin around the patient's eye socket, then align the adaptive sealing base 1 with the injured eye's orbital area and gently press it. During this process, the biomimetic adsorption structure 4 located at the lower edge of the adaptive sealing base 1 adheres tightly to the skin surface, forming a reliable primary seal through the negative pressure adsorption effect generated by the micron-level suction cup. Next, medical personnel use a matching miniature manual air pump connected to the inflation port 5 to inject an appropriate amount of air into the inflatable sealing ring 31 pre-embedded inside the adaptive sealing base 1. As the sealing ring gradually expands, its elastic surface adaptively fills the microscopic gaps caused by facial bone contour undulations or skin texture, establishing a strong secondary dynamic seal. At this point, medical personnel can perform preliminary treatment on the eye wound through the operating hole 2 in the center of the adaptive sealing base 1, such as administering antibiotic eye drops. This design avoids prolonged exposure of the wound to the external environment before the device is fully closed.

[0061] When closure is required, the iron alloy ring 8 at the bottom edge of the rigid transparent outer cover 7 is aligned with the annular permanent magnet array 3 around the self-adaptive sealing base 1. The two quickly attract and close under strong magnetic force, producing a clear locking sound. The magnetic latch design ensures a one-click, rapid seal, and the entire process can be completed within seconds. Subsequently, the quick-fix strap 32 is wrapped around the patient's head and connected to both sides of the self-adaptive sealing base 1 via the buckle 33. The Velcro strap is adjusted to a suitable tightness, providing additional mechanical fixation for the entire device and preventing overall displacement during strenuous activity.

[0062] After the device is sealed, the micro-positive pressure maintenance system is activated. The miniature diaphragm air pump 17 begins operation, purifying outside air through a HEPA-grade air filter 19 and delivering it into the cavity via tubing. The system pressure is primarily regulated by a mechanical pressure valve 20. When the mechanical pressure valve 20 senses that the cavity pressure exceeds a preset upper limit, the pressure feedback diaphragm within the mechanical pressure valve 20 pushes the valve core to open the exhaust channel; when the pressure returns to the normal range, the valve core resets and closes. Simultaneously, the mechanical pressure self-regulating unit 21 operates synchronously as a precision redundant control device: when the cavity pressure abnormally rises above the safety threshold, the pressure acting on the lever counterweight mechanism 22 increases, overcoming the balance torque set by the counterweight, driving the lever to tilt and pushing the slide valve 23 to open the pressure relief channel; once the pressure returns to normal, the lever automatically resets under the action of the counterweight, and the slide valve 23 closes. This dual mechanical control system ensures a continuous pressure range of 20-25 mmHg, and medical personnel can observe the pressure data in real time through the mechanical pressure gauge 18 inside the pressure monitoring window 9 at the top of the rigid transparent outer casing 7.

[0063] When facing complex mechanical environments during transport, the components exhibit highly coordinated protective performance. When the ambulance travels over uneven roads and experiences vertical bumps, the universal shock absorber bracket 11, connecting the adaptive sealing base 1 and the rigid transparent outer casing 7, responds immediately: the conical compression spring 13 in each spring-damping composite unit 12 first undergoes elastic deformation, absorbing and storing most of the impact kinetic energy; simultaneously, the damping silicone pillars 14 coaxially filled inside the springs generate significant viscous shear deformation, converting mechanical energy into heat dissipation. This composite mechanism effectively attenuates the main damaging low-frequency vibrations. The axial limiting ring 15, fitted outside the composite unit, ensures that the damping stroke is always within a safe range, preventing rigid collisions.

[0064] When the vehicle turns and generates lateral acceleration, the unique structure of the universal shock absorber bracket 11 allows for multi-directional relative displacement. The ball joint design at the lower end of the spring-damping composite unit 12 allows each unit to independently adapt to forces in different directions, offsetting the direct effect of lateral inertial forces on the eyeball through three-dimensional elastic deformation. Simultaneously, the eyeball stabilization system located within the cavity is activated: the elastic support arm 29, made of shape memory alloy, maintains a preset curvature under body temperature, and its adjustable contact ring 28 gently contacts the equator of the eyeball with a contact pressure of less than 2 mmHg. When the eyeball attempts lateral displacement due to inertia, the friction between the porous silicone surface of the adjustable contact ring 28 and the eye tissue provides a gentle but continuous restraining force, controlling the horizontal displacement to below 0.3 mm.

[0065] When faced with the front-to-back impacts generated by vehicle acceleration or braking, the dual protection mechanism once again works synergistically. The omnidirectional shock absorber 11 absorbs linear impact energy through its axial compression and tension, while the elastic support arm 29 of the eye stabilization system generates a restoring torque opposite to the direction of eye movement through its unique shape memory characteristics, effectively suppressing the anterior-posterior displacement of the eyeball in the sagittal plane. This dual mechanism of "external shock absorption + internal stabilization" enables the device to maintain the relative spatial stability of the eyeball even under complex motion conditions.

[0066] When medical intervention is required, the sterile drug delivery interface 24 provides a complete solution. Through the self-sealing diaphragm 25 of the main drug delivery channel, healthcare personnel can directly inject medication using a syringe. The silicone diaphragm closes instantly after the needle is withdrawn, maintaining a tight seal. If exudate accumulates within the cavity, the one-way valve in the auxiliary drainage channel 26 automatically opens under hydrostatic pressure to drain the fluid. Once the pressure from the accumulated fluid is released, the one-way valve automatically closes, maintaining stable internal pressure. This dual-channel design enables treatment operations under completely sealed conditions, completely avoiding the drawbacks of traditional devices that require breaking the seal to perform medical procedures.

[0067] Throughout the entire transfer process, the dual sealing mechanism 30 continuously ensures reliable sealing. When the pressure inside the cavity fluctuates due to environmental changes, the elastic properties of the inflatable sealing ring 31 allow it to adaptively adjust the contact pressure, ensuring effective sealing under different pressure conditions. In the event of an unexpected pressure drop, the magnetic latch provides a secure self-locking mechanism, effectively preventing accidental opening of the device.

[0068] This device achieves multiple technological breakthroughs through the precise coordination and synergy of its various subsystems. The adaptive sealing base 1 and the dual sealing mechanism 30 together construct a dynamically adaptive multi-sealing system, significantly improving the device's adaptability to different facial anatomy structures and effectively eliminating the risk of leakage. The "internal and external protection" mechanism formed by the universal shock-absorbing bracket 11 and the eyeball stabilization system achieves comprehensive protection from external vibration attenuation to internal displacement suppression, reducing the displacement of the eyeball during transport to a safe range. The micro-positive pressure maintenance system adopts a purely mechanical dual control strategy, ensuring both the accuracy and reliability of pressure control while avoiding reliance on electronic components. The innovative design of the sterile drug delivery interface 24 overcomes the technical bottleneck of medical operations in a sealed environment. The quick-fixing strap 32 enhances the overall stability of the device. These systems work together to create a safe, sealed, stable, and treatable ideal transport environment for patients with perforated eyeballs, significantly improving the success rate of treatment and the quality of prognosis.
