Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical care instruments, in particular to an eye moisturizing and nursing device for neurocritical patients. BACKGROUND

[0002] Neurocritical patients often have incomplete eyelid closure due to central nervous system damage, which means that the patient's eyes may not be fully closed. This condition usually occurs in patients in the intensive care unit. The cause of this incomplete eyelid closure is damage to the central nervous system, such as stroke, brain trauma, etc., resulting in loss of nerve function controlling eyelid closure. A serious consequence of incomplete eyelid closure is the loss of the blink reflex. The blink reflex is the natural blinking response when the eye is stimulated, and it is a mechanism to protect the eye. When this reflex is lost, tears evaporate too quickly, exposing the cornea to a dry environment.

[0003] Because the cornea is in a dry state for a long time, it greatly increases the risk of exposure keratitis and corneal ulcer. Exposure keratitis is an inflammation of the cornea caused by prolonged exposure, which can cause eye pain, photophobia, decreased vision, and other symptoms. Corneal ulcer is an ulcer formed by severe damage to the corneal tissue, which can cause blindness, and its incidence in neurocritical patients such as stroke, brain trauma, etc. can be as high as 40%-70%.

[0004] Therefore, in view of the above-described eye problems of neurocritical patients, there is an urgent need to develop an effective treatment method or auxiliary device aimed at helping patients improve eyelid closure function, enhance the blink reflex, and thus protect the cornea from exposure keratitis and corneal ulcer.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figures 1-9 As shown, an embodiment of the present invention provides an eye moisturizing care device for critically ill neurological patients, comprising an intelligent control host and an eye care unit. The intelligent control host is placed at the bedside and is connected to the eye care unit through a signal transmission component. The intelligent control host is used to precisely control the eye care unit to perform nursing actions such as eye moisturizing and assisting eyelid closure. The two are connected by a wired cable or a wireless communication module to achieve bidirectional data transmission and command interaction.

[0022] like Figures 1-8As shown, the eye care unit comprises two mounting rings 1, a first plastic connecting piece 3, a strap 4 and an L-shaped connecting rod 2. The two mounting rings 1 are symmetrically arranged and correspond to the positions of the patient's two eyes respectively, and are used to be sleeved on both sides of the patient's head; the two mounting rings 1 are fixedly connected by the first plastic connecting piece 3, the first plastic connecting piece 3 can be bent and shaped, and is suitable for different patient head widths and wearing angles. One side of each mounting ring 1 is fixedly connected with an L-shaped connecting rod 2, one end of the L-shaped connecting rod 2 away from the mounting ring 1 extends away from the eye direction, and a first through hole 201 is formed on the rod body, and the mounting ring 1 is also sleeved with a strap 4, the strap 4 is made of elastic material, and can be wrapped around the patient's head to fix the whole device, preventing loosening.

[0023] Among them, the first plastic connecting piece 3 can be a silicon-coated aluminum-magnesium alloy wire, a medical memory alloy wire, a silicon-coated copper wire, etc. It should be noted that the first plastic connecting piece 3 should be able to withstand alcohol, iodophor and other disinfectants commonly used in intensive care units to avoid cross infection.

[0024] As shown in Figures 1-4 The mounting ring 1 is sleeved with an eye cup 5, the eye cup 5 can adapt to the human eye contour, the eye cup 5 is sleeved from one end of the mounting ring 1 away from the L-shaped connecting rod 2, and is used to form a closed eye care space, which is beneficial to the replacement of the eye cup 5 and the repeated use after replacing the consumable eye cup 5.

[0025] The nursing execution mechanism 6 comprises a mounting plate 7, the mounting plate 7 is fixedly connected with a threaded column 8, the eye cup 5 is provided with a second through hole 501 matched with the threaded column 8, and the L-shaped connecting rod 2 is provided with a first through hole 201 matched with the threaded column 8. After the eye cup 5 is installed, the mounting plate 7 needs to be installed, at this time, the threaded column 8 needs to be sequentially inserted through the second through hole 501 and the first through hole 201, and is locked by a nut 9, so as to realize the detachable fixing of the mounting plate 7 and the L-shaped connecting rod 2, which is convenient for subsequent cleaning and replacement. Since the eye cup 5 is clamped between the mounting plate 7 and the L-shaped connecting rod 2, the eye cup 5 can also be fixed well, which is convenient for subsequent cleaning and replacement.

[0026] As shown in Figures 5-8As shown, the lower end of the mounting plate 7 is symmetrically provided with a pair of first side plates 10, and each first side plate 10 is provided with a sliding groove 1001 at the lower end. The nursing execution mechanism 6 further comprises a second side plate 11 matched with the sliding groove 1001, and one side of the second side plate 11 is fixedly connected with a connecting plate 1101 which is slidingly embedded in the sliding groove 1001, and a motorized push rod 12 is installed between the connecting plate 1101 and the bottom wall of the sliding groove 1001, and the two ends of the motorized push rod 12 are fixedly connected with the connecting plate 1101 and the bottom wall of the sliding groove 1001 respectively, and the interval of the second side plate 11 relative to the first side plate 10 can be adjusted by the extension and retraction of the motorized push rod 12, so as to compensate for the interval between the mounting plate 7 and the patient's eyes.

[0027] As shown in the figure, Figures 5-8 The two second side plates 11 are rotatably connected with a screw rod 13, and two positioning columns 14 are fixedly connected therebetween and symmetrically arranged on both sides of the screw rod 13. A sliding block 15 is further arranged between the second side plates 11, and the sliding block 15 is provided with a threaded hole 1501 matched with the screw rod 13 and a third through hole 1502 matched with the positioning column 14, and the screw rod 13 penetrates through the threaded hole 1501 and the positioning column 14 penetrates through the third through hole 1502, so that the sliding block 15 can slide stably in the axial direction, transverse direction and vertical direction of the positioning column 14 under the drive of the screw rod 13. The lower end of the sliding block 15 is fixedly connected with a second plastic connecting piece 16 which can be bent and shaped, and a protective sleeve 17 is sleeved at the end away from the sliding block 15.

[0028] Specifically, the protective sleeve 17 is equivalent to a "hand" in contact with the eyelid, which is made of medical soft silicone material and is used to fit the upper and lower eyelid contours. The second plastic connecting piece 16 and the protective sleeve 17 are driven by the vertical lifting of the sliding block 15 in the direction perpendicular to the eyelid, forcing the upper and lower eyelids to contact each other, thereby simulating the eyelid closing action and compensating for the lack of patient's independent closing function.

[0029] As shown in the figure, Figures 5-7 One of the first side plates 10 is provided with a bearing seat, and a connecting piece 20 is rotatably connected in the bearing seat. The two ends of the connecting piece 20 are fixedly connected with a second bevel gear 19 and a third bevel gear 23 respectively, and the second bevel gear 19 is engaged with the first bevel gear 18 to realize power transmission. The connecting piece 20 comprises a first connecting rod 21, and the first connecting rod 21 is provided with a special-shaped sliding groove 2101. A plug-in rod 22 matched with the special-shaped sliding groove 2101 is slidingly connected to the first connecting rod 21. The third bevel gear 23 is fixedly connected to one end of the plug-in rod 22, and the second bevel gear 19 is fixedly connected to one end of the first connecting rod 21. The special-shaped sliding groove 2101 and the plug-in rod 22 can adapt to the power transmission offset when the interval of the second side plate 11 is adjusted, and can ensure the stability of gear engagement.

[0030] A fourth helical gear 24 is rotatably connected to the electric actuator 12. A connecting shaft 2401 is fixedly connected to the fourth helical gear 24. The connecting shaft 2401 passes through the first side plate 10 and is rotatably connected to the first side plate 10. A motor 25 is fixedly connected to the lower end of the mounting plate 7. The output shaft of the motor 25 is connected to the connecting shaft 2401 to provide power to the fourth helical gear 24. The fourth helical gear 24 meshes with the third helical gear 23 to form a complete power transmission chain. A waterproof shell is also fixedly connected to the lower end of the mounting plate 7. The waterproof shell covers the connection between the motor 25 and the connecting shaft 2401 to prevent atomized water vapor from entering the eye cup 5 and to avoid short-circuiting and damaging the motor 25.

[0031] like Figures 5-9 As shown, the mounting plate 7 is also equipped with a water mist nozzle 26, a miniature camera 27, a heating module 28, and a monitoring probe 29. Each component is electrically connected to the intelligent control host to work together to achieve the functions of moisturizing, monitoring, and temperature control.

[0032] The intelligent control host is an independent cabinet structure, placed next to the hospital bed for easy operation and observation by medical staff. Internally, it integrates a central control module 30, a touch display screen 31, operation buttons 32, an alarm module 35, and the main body of the atomizing module 33. The atomizing output pipe of the atomizing module 33 passes through the main unit cabinet, extends to the mounting plate 7, and connects to the water mist nozzle 26. The signal acquisition end of the monitoring module 34 is electrically connected to the miniature camera 27, the heating module 28, the monitoring probe 29, and the atomizing module 33, realizing a linkage mechanism of remote control of the main unit, on-site execution of units, and real-time parameter feedback.

[0033] Specifically, the water mist nozzle 26 is installed on the side of the mounting plate 7 facing the eye and is connected to the output pipe of the atomization generation module 33 to evenly spray the atomized moisturizing liquid into the eye cup 5; the miniature camera 27 is used to visually monitor the patient's eye condition and provide real-time feedback on the eyelid closure status and corneal moisture; the heating module 28 is used to heat the air inside the eye cup 5 to maintain a suitable ambient temperature; and the monitoring probe 29 is used to collect environmental parameters such as temperature and humidity inside the eye cup 5 to provide adjustment basis for the intelligent control host.

[0034] like Figure 9 As shown, the central control module 30 is the core of the intelligent control host. It uses an STM32F103 microcontroller to receive instructions, process data, output control signals, and coordinate the collaborative work of various modules.

[0035] The touch display screen 31 and operation buttons 32 are electrically connected to the central control module 30. The touch display screen 31 is used to display the device's operating status, nursing parameters, alarm information, etc., and also supports medical staff to input control commands via touch, such as adjusting the nebulization volume and eyelid closure frequency. The operation buttons 32 are physical buttons, including start / stop buttons, emergency pause buttons, mode switching buttons, etc., for quick device operation and adaptability to different nursing scenarios.

[0036] The nebulization module 33 is integrated into the intelligent control host next to the hospital bed. Its nebulization output pipeline passes through the host cabinet, extends to the mounting plate 7, and connects to the water mist nozzle 26. The module is electrically connected to the central control module 30 and is controlled by the central control module 30 to start and stop the nebulization moisturizing function and adjust the nebulization volume. At the same time, the nebulization module 33 integrates parameter detection sensors, which can detect the remaining moisturizing liquid volume, nebulization pressure, nebulization rate, and other operating parameters in real time, and transmit these parameters synchronously to the monitoring module 34 to provide the central control module 30 with adjustment basis to ensure that the nebulization effect is adapted to the patient's needs.

[0037] The monitoring module 34 is the core for parameter aggregation and transmission. Its signal acquisition end is divided into multiple parts. One part is electrically connected to the miniature camera 27, heating module 28, and monitoring probe 29 to collect real-time temperature and humidity parameters within the eye cup 5, visual images of the eye, and the working status of the heating module 28. Another part is electrically connected to the main body of the nebulization module 33 to receive parameters such as remaining liquid volume and nebulization pressure fed back by the module. After integrating the collected environmental parameters, equipment operating parameters, and eye status images, the monitoring module 34 feeds them back in real time to the central control module 30 in the bedside host through the signal transmission component, ensuring that the nursing process is precise and controllable.

[0038] The alarm module 35 is electrically connected to the central control module 30. The module integrates a buzzer 36 and an indicator light 37, both of which are electrically connected to the alarm module 35. When the central control module 30 determines that the parameters fed back by the monitoring module 34 exceed a preset threshold, or when a device malfunctions, it immediately sends a control signal to the alarm module 35, driving the buzzer 36 to sound an alarm and the indicator light 37 to flash. Simultaneously, the alarm type and abnormal parameters are displayed on the touch screen 31, alerting medical personnel to handle the situation promptly.

[0039] In this embodiment, the usage procedure of the eye moisturizing care device for critically ill neurological patients is as follows: Wearing process: The device is worn on the patient's head via the mounting ring 1 and strap 4. The position of the eye cup 5 is adjusted so that the protective cover 17 fits the eyelid. Medical staff input nursing parameters, including nebulization volume, temperature and humidity thresholds inside the eye cup 5, and the frequency and stroke of eyelid assisted closure, through the touch screen 31 or operation buttons 32 of the intelligent control host at the bedside. The central control module 30 receives the parameters and initializes the device.

[0040] Moisturizing Care Process: Medical staff issue moisturizing commands via the touchscreen display 31 or operation buttons 32 of the bedside intelligent control host. Upon receiving the command, the central control module 30 sends a start signal to the atomizing module 33. The module starts and generates atomized moisturizing liquid, which is delivered to the water mist nozzle 26 through a pipe extending to the mounting plate 7. After atomization, the liquid is evenly delivered into the eye cup 5, creating a closed, moisturized nursing environment for the patient's eyes. During this process, the atomizing module 33 monitors its remaining liquid volume and atomization pressure parameters in real time, while the monitoring module 34 simultaneously collects temperature and humidity parameters within the eye cup 5. These two sets of parameters are then fed back to the central control module 30. If the central control module 30 determines that the parameters exceed preset thresholds, it immediately and automatically adjusts the operating parameters of the atomizing module 33, or prompts medical staff to manually adjust them via the touchscreen display 31, maintaining a stable nursing environment. Simultaneously, the heating module 28 is activated under the control of the central control module 30, maintaining the temperature within the eye cup 5 within a preset range to enhance patient comfort.

[0041] Eyelid Assisted Care Process: The central control module 30 controls the motor 25 to start. The motor 25 drives the fourth helical gear 24 to rotate through the connecting shaft 2401. The fourth helical gear 24 drives the third helical gear 23 and the connector 20 to rotate, which in turn drives the screw 13 to rotate through the second helical gear 19 and the first helical gear 18. Under the action of the screw 13 and the positioning column 14, the slider 15 slides vertically to the eye along the axial direction, driving the second malleable connector 16 and the protective sleeve 17 to move, forcing the upper and lower eyelids to contact, thus achieving assisted eyelid closure and opening. If it is necessary to adapt to the height of the patient's eye and the nursing actuator 6, the central control module 30 controls the extension and retraction of the electric push rod 12 to adjust the distance of the second side plate 11. The irregular groove 2101 of the connector 20 slides relative to the plug rod 22 to ensure stable gear meshing and not affect power transmission.

[0042] In this embodiment, the beneficial effects of the eye moisturizing care device for critically ill neurological patients include at least the following: The adjustable structure, consisting of the first malleable connector 3, the second malleable connector 16, and the electric push rod 12, can be adapted to different patients' head sizes, eye widths, and wearing angles. It is stable and comfortable to wear, meeting the personalized needs of critically ill neurological patients.

[0043] It compensates for the functional defects of patients with incomplete eyelid closure and loss of blink reflex. Combined with the closed environment of the eye cup 5 and the closed-loop regulation of atomization and moisturization, it effectively slows down tear evaporation and maintains corneal moisture. It can significantly reduce the incidence of exposure keratitis and corneal ulcers. The miniature camera 27 monitors the eye condition in real time, which makes it easier for medical staff to grasp the nursing effect in a timely manner and further protect corneal health.

[0044] Example 2: Unlike Embodiment 1, the mounting plate 7 of the eye care unit has a pre-reserved modular mounting slot. The atomization module 33 adopts a miniaturized design and is integrated into the mounting slot of the mounting plate 7, rather than being placed in the main unit cabinet next to the bed. It only achieves power supply and signal interaction with the intelligent control host next to the bed through the power cord, which greatly shortens the length of the atomization output pipeline and reduces the risk of pipeline blockage and leakage.

[0045] The atomization output end of the atomization module 33 is directly and sealed to the water mist nozzle 26, eliminating the need for long-distance pipeline extension. The parameter detection sensor integrated into the module is directly electrically connected to the signal acquisition end of the monitoring module 34, resulting in lower data transmission latency and enabling real-time and precise adjustment of atomization parameters. To accommodate miniaturization, the atomization module 33 adopts a micro peristaltic pump structure, which is compact, low-noise, and has a removable and replaceable liquid tank, facilitating timely replenishment of moisturizing solution by medical personnel while avoiding cross-infection.

[0046] The intelligent control host is still a bedside independent cabinet structure, which integrates a central control module 30, a touch screen 31, operation buttons 32, an alarm module 35 and a power supply module. It is connected to components such as the atomizing module 33, motor 25 and electric push rod 12 on the mounting plate 7 through wired wires to ensure stable power supply and reliable command transmission.

[0047] The usage process in this embodiment is basically the same as in Embodiment 1. The only difference is that the atomization module 33 has a faster start-up and adjustment response speed during the moisturizing care process. Also, due to the shortened tubing, the atomized moisturizing liquid can be delivered into the eye cup 5 more quickly and evenly through the water mist nozzle 26. At the same time, the miniaturized integrated design slightly increases the overall weight of the eye care unit, but it eliminates the need to drag long tubing, making it suitable for scenarios with slight changes in patient position and improving the flexibility of care.

[0048] The beneficial effects of this embodiment are as follows: while retaining the core functions of embodiment one, the miniaturized integration of the nebulization generation module 33 reduces pipeline losses and failure points, improves the response speed and stability of nebulization care, adapts to the needs of patients with mild activity, and simplifies the moisturizing solution replenishment process, reducing the difficulty of operation for medical staff.

[0049] Example 3: Unlike Examples 1 and 2, the eye cup 5 is made of medical-grade high-transparency polycarbonate material and is injection molded in one piece. The overall light transmittance is ≥92%. Medical staff can directly observe the patient's eyelid closure, corneal moisture and the movement of the protective sleeve 17 through the eye cup 5. The initial nursing assessment can be completed without disassembling the device.

[0050] To address the issue of water vapor obstructing vision on the inner wall of the eye cup 5 during the atomization and moisturizing process, this embodiment adds a double-layered vacuum anti-fog observation window to the side of the eye cup 5 facing the medical staff. The inner side of the observation window is coated with a nano-hydrophilic anti-fog coating, while the outer side is treated with scratch-resistant and wear-resistant materials. Simultaneously, micro-ventilation holes are pre-drilled at the edge of the eye cup 5, with built-in hydrophobic filter membranes to balance the air pressure inside and outside the eye cup 5, reducing water vapor condensation and achieving unobstructed visibility throughout the atomization and moisturizing process.

[0051] Obviously, the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
