Description

Technical Field

[0001] This invention relates to the field of medical and nursing device technology, specifically to an intelligent controlled prone positioning device for ophthalmic clinical nursing. Background Technology

[0002] In ophthalmic clinical nursing, the prone position is mainly used for postoperative positioning management of patients with retinal detachment after vitrectomy combined with intraocular tamponade. Specifically, for complex retinal detachments, the vitreous humor is often removed during surgery, and silicone oil or intumescent inert gas is injected into the eye as a tampon. Postoperatively, in order for the tampon to float to the posterior pole of the eyeball by means of buoyancy and surface tension, continuously press against and close the retinal tear, and promote the adhesion and repositioning of the retinal neuroepithelium and pigment epithelium, the patient must strictly maintain a prone position with their face down. Improper positioning or deviation may lead to tampon displacement, reopening of the retinal tear, or even surgical failure and permanent visual impairment.

[0003] Currently, devices used clinically to assist patients in maintaining a prone position include U-shaped pillows or inflatable cushions for lying face down, prone care beds with oval ventilation holes in the mattress, and support-type prone devices with basic support functions. These existing devices provide head support and ventilation to some extent. However, in clinical application, these devices have the following shortcomings:

[0004] First, the body position angle is fixed and the ability to adjust is weak, making it impossible to precisely adjust the tilt angle of the head. Most existing prone positioning devices only provide a single fixed head support angle, and the patient's cervical spine can only maintain one posture throughout the entire long period of maintaining the position, without being able to make fine adjustments to the angle according to individual comfort needs or medical orders.

[0005] Second, the devices have poor adaptability to different head shapes and facial contours. There are significant individual differences in facial features such as forehead width, cheekbone height, and cheek fullness among different patients. Existing devices often use fixed-size facial support components or only offer basic adjustment levels, making it difficult to achieve precise adaptation to the specific facial features of individual patients.

[0006] Third, there is a lack of intelligent control methods. The existing devices rely primarily on manual adjustments by medical staff or family members for tasks such as angle adjustment and support position adjustment. This is not only cumbersome and time-consuming, but also makes it difficult to accurately record and reproduce the adjustment parameters. When the device needs to be used multiple times for the same patient or to maintain a consistent position at different times, it often requires repeated adjustments based on the operator's experience, limiting the accuracy and efficiency of positional care. Summary of the Invention

[0007] This invention aims to provide an intelligent controlled prone positioning device for ophthalmic clinical care. It includes a pair of facial support components, with a first telescopic component controlling the pitch angle of the facial supports and a second telescopic component controlling the distance between the two facial support components. This adaptable device can meet various clinical needs. Furthermore, an intelligent control unit controls the operation of both the first and second telescopic components, providing convenient, precise, and efficient control. This invention solves the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An intelligent controlled prone positioning device for ophthalmic clinical care includes a base plate. The base plate is connected to a body position maintaining assembly and a pair of facial support assemblies. The body position maintaining assembly includes a main airbag and a pair of bronchial airbags, respectively located on the left and right sides of the main airbag and communicating with it. When the main airbag is compressed, gas inside the main airbag flows to the pair of bronchial airbags. The facial support assembly includes a support plate, detachably connected to a facial support pad and a restraint strap. The base plate is also connected to a first telescopic assembly, an intelligent control unit, and a central shaft. The support plate is connected to a connecting sleeve that mates with the central shaft. The connecting sleeve is slidably fitted onto the outside of the central shaft. The end of the support plate away from the connecting sleeve is rotatably connected to the telescopic end of the first telescopic assembly. The two support plates of the pair of facial support assemblies are connected via a second telescopic assembly. The intelligent control unit is electrically connected to the first and second telescopic assemblies for powering and controlling them.

[0010] Furthermore, the substrate is rotatably connected to a pair of arm supports, and the pair of arm supports are located on the outside of the pair of face support assemblies.

[0011] Furthermore, the arm support is provided with a length adjustment assembly, which includes an internal threaded cylinder and two external threaded rods with opposite thread directions. The two external threaded rods are threadedly connected to both ends of the internal threaded cylinder. When the internal threaded cylinder is rotated, the two external threaded rods move in a straight line towards each other along the axial direction of the internal threaded cylinder.

[0012] Furthermore, an inflation assembly is provided between the pair of arm supports. The inflation assembly includes a groove, an inflation outer cylinder, and a piston rod assembly. The groove is fixedly connected to the arm support, the inflation outer cylinder is fixedly connected to the base plate, the operating rod of the piston rod assembly is slidably connected to the groove, and the piston of the piston rod assembly is slidably and sealingly connected to the inflation outer cylinder. The main airbag cushion and / or the ventral airbag cushion are connected to the inflation end of the inflation outer cylinder via an air guide pipe. Both the inflation outer cylinder and the air guide pipe are connected to a control... A one-way gas valve controls the unidirectional flow of gas. The one-way gas valve connected to the inflation outer cylinder controls the unidirectional flow of gas from the outside to the inside of the inflation outer cylinder. The one-way gas valve connected to the gas guide pipe controls the unidirectional flow of gas from the inflation outer cylinder to the inside of the main airbag pad and / or the branch airbag pad. When the arm support oscillates periodically relative to the base plate, the operating rod of the piston rod assembly slides back and forth along the slotting direction of the groove, and the piston of the piston rod assembly slides periodically along the axial direction of the inflation outer cylinder. The inflation assembly inflates the main airbag pad and / or the branch airbag pad.

[0013] Furthermore, both the main airbag cushion and the bronchus cushion have self-recovery properties, and the self-recovery coefficient of the main airbag cushion is greater than that of the bronchus cushion; in a static state, the inflation degree of the main airbag cushion is greater than that of the bronchus cushion.

[0014] Furthermore, both the support plate and the facial support pad are arc-shaped, and the arcs of the two support plates and / or two facial support pads of a pair of facial support components are arranged opposite each other, forming a "()" shape.

[0015] Furthermore, both the first telescopic component and the second telescopic component are electrically operated telescopic rods, and the second telescopic component is a bidirectional telescopic rod. The two support plates of the pair of face support components are respectively fixedly connected to the telescopic ends of the two telescopic rods of the second telescopic component.

[0016] Furthermore, a slider is fixedly connected to the fixed end of the first telescopic component, and a groove is provided on the upper side of the substrate to cooperate with the slider, and the slider is slidably disposed inside the groove.

[0017] Furthermore, on the opposite sides of the two support plates of the pair of facial support components: one support plate is fixedly connected to a guide post, and the other support plate has a groove that cooperates with the guide post, and the guide post slides through the groove.

[0018] Furthermore, the intelligent control unit also integrates a multimedia unit and several control buttons. The multimedia unit includes a display screen and a smart speaker. The several control buttons control the operation of the first telescopic component, the second telescopic component, and the smart speaker respectively, and display the operating status of the three on the display screen.

[0019] The principles and beneficial effects of the technical solution are as follows:

[0020] 1. This invention provides an intelligent controlled prone positioning device for ophthalmic clinical care, comprising a base plate as a support foundation, on which a body position maintaining component and a pair of facial support components are connected. One end of the support plate of the facial support component is slidably fitted onto the central axis via a connecting sleeve, and the other end is rotatably connected to the telescopic end of a first telescopic component; the pair of support plates are connected by a second telescopic component. An intelligent control unit is electrically connected to the first and second telescopic components for power supply and precise control of both. In use, the intelligent control unit controls the extension and retraction of the first telescopic component according to clinical needs, causing the support plate to rotate around the central axis, thereby precisely adjusting the pitch angle of the facial support component relative to the base plate to meet specific head position requirements; simultaneously, it controls the extension and retraction of the second telescopic component, causing the pair of support plates to slide relative to each other along the central axis axially, infinitely adjusting the distance between the two support plates. This invention solves the defects of existing devices, such as fixed body position angle, weak control capability, and inability to precisely adjust the head pitch angle. Through electrified and intelligent coordinated control, it achieves independent and precise adjustment of the pitch angle and the width of the facial support, improving the accuracy and convenience of body position management.

[0021] 2. This invention provides an intelligent controlled prone positioning device for ophthalmic clinical care. The position maintenance component includes a main airbag and a pair of bronchial airbags, which are respectively located on the left and right sides of the main airbag and are interconnected. When the patient lies prone and the chest compresses the main airbag, the main airbag deforms under pressure, and the gas inside is squeezed to flow to the bronchial airbags on both sides, causing the bronchial airbags to quickly inflate. The inflated bronchial airbags conform to the patient's torso from both sides, forming a passive lateral clamping and support, effectively limiting the patient's lateral swaying or displacement during prone positioning. In conjunction with the facial support component, it ensures the continuous stability of the overall position. This passive inflation linkage structure requires no additional power source, converting the patient's own weight into a restraining force for stable positioning, making up for the lack of effective position maintenance devices in the prior art, while avoiding the complexity and noise that may be caused by active inflation systems.

[0022] 3. This invention provides an intelligent controlled prone positioning device for ophthalmic clinical care. A pair of arm supports are rotatably connected to a base plate, and an inflation assembly is disposed between the arm supports. The inflation assembly includes a groove, an inflation outer cylinder, and a piston rod assembly. The groove is fixed to the arm supports, the inflation outer cylinder is fixed to the base plate, and the operating rod of the piston rod assembly is slidably connected to the groove. When the patient's arm is placed on the arm supports, and due to prolonged prone positioning, slight periodic swings or active movements occur, the arm supports cause the groove to swing relative to the base plate. The groove drives the operating rod to cause the piston to reciprocate within the inflation outer cylinder. Through the cooperation of a one-way gas valve, the inflation outer cylinder continuously draws air from the outside and pressurizes it into the main airbag and / or bronchus airbag, achieving automatic air replenishment. It converts the unavoidable slight movements of the patient into beneficial energy to maintain the pressure of postural support, ensuring that the airbag remains fully supported during prolonged use without manual intervention or external air source, saving energy, protecting the environment, and improving the continuous reliability of use.

[0023] 4. This invention provides an intelligent controlled prone positioning device for ophthalmic clinical care. Both the support plate and the facial support pad are arc-shaped. A pair of support plates and their respective facial support pads are positioned opposite each other, forming an overall "()" shape to create a wraparound support that conforms to the physiological curvature of the human cheek. Simultaneously, the facial support pad is detachably connected to the support plate, facilitating the replacement of support pads with different thicknesses or firmnesses. Combined with the precise adjustment of the distance between the pair of support plates by a second telescopic component, the device can provide personalized and precise adaptation to different patients' forehead width, cheekbone height, and cheek fullness. It effectively solves the problems of poor adaptability to different head shapes and facial contours, and the tendency to cause localized pressure concentration in existing devices. It increases the facial support area, makes the pressure distribution more uniform, reduces the risk of pressure sores, and improves the comfort of patients during prolonged prone positioning.

[0024] 5. This invention provides an intelligent controlled prone positioning device for ophthalmic clinical nursing. Both the main airbag and the bronchial airbag have self-recovery properties, with the self-recovery coefficient of the main airbag being greater than that of the bronchial airbag. In a static, pressure-free state, the initial inflation degree of the main airbag is greater than that of the bronchial airbag. This ensures that when the patient is initially prone, the chest receives full and soft support from the main airbag, guiding the patient into the correct position. When the chest is compressed, gas is transferred, and the bronchial airbag inflates to its proper position, forming lateral fixation. Once the patient lifts to relieve pressure, the main airbag, with its greater self-recovery force, preferentially rebounds for inhalation, preparing for the next compression, while the bronchial airbag maintains its shape appropriately, preserving the basic contour of lateral restraint. This further ensures the responsiveness and stability of the support form of the positioning component under dynamic pressure changes.

[0025] 6. This invention provides an intelligent controlled prone positioning device for ophthalmic clinical nursing. The intelligent control unit also integrates a multimedia unit and several control buttons. The multimedia unit includes a display screen and a smart speaker. The control buttons can respectively operate the first telescopic component, the second telescopic component, and the smart speaker, with the operating status displayed on the screen in real time. Patients can independently make fine adjustments to the angle and spacing using simple buttons, and can play audio and video content to distract their attention and alleviate the boredom and anxiety caused by prolonged prone positioning. It integrates body position control with patient psychological comfort management, solving the problems of lack of intelligent control methods, cumbersome operation, and poor patient compliance in existing devices, transforming prone positioning care from passive endurance to an active, controllable, and comfortable experience that takes into account both physical and mental well-being.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0036] Example 1: As Figures 1 to 4 As shown, an intelligent controlled prone positioning device for ophthalmic clinical care includes a base plate 1, which serves as the supporting foundation for the entire device. The bottom of the base plate can be equipped with an anti-slip pad to facilitate transfer between different hospital beds or stable placement. A body position maintenance component and a pair of facial support components are connected to the top of the base plate 1. The pair of facial support components are symmetrically arranged on both sides above the body position maintenance component to jointly provide coordinated support for the patient's head, face, and torso in a prone position.

[0037] The body positioning component supports the chest and abdominal area of ​​a patient when prone. It includes a main airbag 8 and a pair of ventricular airbags 9. The main airbag 8 is located in the middle of the upper side of the base plate 1 and is arranged laterally. The pair of ventricular airbags 9 are located on the left and right sides of the main airbag 8, respectively, and both ventricular airbags 9 are connected to the main airbag 8 through internal airways. Both the main airbag 8 and the ventricular airbags 9 are made of a self-healing flexible material, such as medical-grade silicone, and the self-healing coefficient of the main airbag 8 is greater than that of the ventricular airbags 9. In a static, uncompressed natural state, the initial inflation degree of the main airbag 8 is greater than that of the ventricular airbags 9, so that the patient's chest first contacts the full and soft main airbag 8 when initially prone. When the patient lies prone and the chest is compressed against the main airbag 8, the main airbag 8 is deformed by the compression. The air inside is squeezed to flow towards the pair of bronchus airbags 9, causing the bronchus airbags 9 to quickly inflate and expand, adhering to the sides of the patient's torso from the left and right sides, forming a passive lateral clamping and support, effectively limiting the patient's body from side to side or shifting during a long period of prone position.

[0038] The facial support assembly includes a support plate 2, with a facial support pad 3 and a restraint strap 7 detachably connected to the upper side of the support plate 2. Both the support plate 2 and the facial support pad 3 are arc-shaped. The two support plates 2 and the two facial support pads 3 on them are arranged opposite each other in an "()" shape, forming a wraparound support structure that conforms to the physiological curvature of the human face. The facial support pad 3 can be made of memory foam material and is detachably connected to the support plate 2 via Velcro, facilitating the replacement of support pads of different thicknesses or firmnesses according to the patient's facial contours and also facilitating cleaning and disinfection after use. The restraint strap 7 is connected to the outer side of the support plate 2 and is a flexible strap used to lightly secure the patient's head to the facial support assembly during use, preventing the patient's face from slipping or shifting during prolonged prone positions.

[0039] The base plate 1 is also connected to a first telescopic component 4, an intelligent control unit 6, and a central shaft 11. The central shaft 11 is vertically fixed to the upper side of the base plate 1. The support plate 2 is connected to a connecting sleeve 12 that cooperates with the central shaft 11. The connecting sleeve 12 is slidably sleeved on the outside of the central shaft 11, so that the support plate 2 can rotate around the axis of the central shaft 11 to adjust the pitch angle, and can also slide back and forth along the axial direction of the central shaft 11 to adapt to the adjustment requirements of different facial support component spacings. The end of the support plate 2 away from the connecting sleeve 12 is rotatably connected to the telescopic end of the first telescopic component 4. In this embodiment, the first telescopic component 4 is an electric telescopic rod, and a slider 13 is fixedly connected to its lower end. The upper side of the base plate 1 is provided with a groove that cooperates with the slider 13. The slider 13 is slidably disposed inside the groove, so that the fixed end of the first telescopic component 4 can move synchronously with the sliding of the support plate 2 along the axial direction of the central shaft 11.

[0040] The two support plates 2 of a pair of facial support components are connected by a second telescopic component 5. In this embodiment, the second telescopic component 5 is a bidirectional electric telescopic rod, with telescopic rods at both ends that can extend or retract independently or synchronously. The two support plates 2 of the pair of facial support components are fixedly connected to the telescopic ends of the two telescopic rods of the second telescopic component 5, respectively. To improve the guiding accuracy and structural stability when the two support plates 2 slide relative to each other, a guide structure is also provided between the opposite sides of the two support plates 2 of the pair of facial support components: a guide post 15 is fixedly connected to the opposite side of one support plate 2, and a groove 14 that cooperates with the guide post 15 is opened on the opposite side of the other support plate 2, with the guide post 15 slidingly passing through the groove 14. When the second telescopic component 5 extends or retracts, the two support plates 2 move smoothly relative to each other along the central axis 11 under the guidance of the cooperation between the guide post 15 and the groove 14, without deflection or shaking.

[0041] The intelligent control unit 6 is fixedly mounted on the upper side of the base plate 1. The intelligent control unit 6 is electrically connected to the first telescopic component 4 and the second telescopic component 5, and is used to provide driving power to the first telescopic component 4 and the second telescopic component 5 and issue control commands. The intelligent control unit 6 also integrates a multimedia unit and several control buttons. The multimedia unit includes a display screen and a smart speaker. The control buttons correspond to the functions of controlling the extension and retraction of the first telescopic component 4 and the second telescopic component 5, as well as the playback, pause, and volume adjustment of the smart speaker. The real-time operating status of the above three components is clearly displayed on the display screen in the form of text or icons.

[0042] A pair of arm supports 10 are rotatably connected to the upper side of the base plate 1. The arm supports 10 are respectively located outside a pair of face support components, used to support the patient's arms when naturally extended forward or placed on either side of the head while lying prone. The rotatable connection between the arm supports 10 and the base plate 1 allows the arm supports 10 to adjust their opening angle in the horizontal plane to accommodate different patients' arm placement preferences. The arm supports 10 also include a length adjustment component 17 for adjusting their effective support length. The length adjustment component 17 includes an internally threaded cylinder and two externally threaded rods with opposite thread directions. The two externally threaded rods are threaded to both ends of the internally threaded cylinder, and their outer ends are connected to the two end structures of the arm supports 10. When the internally threaded cylinder on the arm supports 10 is rotated, the two externally threaded rods move linearly towards each other along the axial direction of the internally threaded cylinder, thereby shortening or lengthening the overall length of the arm supports 10 to accommodate patients with different arm lengths.

[0043] To prevent external light interference when the patient is prone, this device can also be equipped with an outer cover 16. The outer cover 16 is detachably mounted above the first telescopic component 4, the second telescopic component 5 and the intelligent control unit 6. Ventilation holes or observation windows can be opened on the front or sides of the outer cover 16 to create a quiet and light-proof prone environment for the patient while ensuring ventilation and facilitating observation by medical staff.

[0044] The specific implementation process of this embodiment is as follows:

[0045] When using this prone positioning device, first, place the device securely on the hospital bed or nursing table. Then, according to the patient's face size and head shape, operate the corresponding control button on the intelligent control unit 6 to control the extension and retraction of the second telescopic component 5, causing the two support plates 2 to move relative to each other along the central axis 11, adjusting the distance between the two support plates 2. Guided by the cooperation of the guide post 15 and the groove 14, the two support plates 2 slide smoothly until the two facial support pads 3 fit well against the patient's cheeks, forming a supportive state with moderate clamping without pressure or discomfort. Simultaneously, according to the clinically required head tilt angle, operate the control button to control the extension and retraction of the first telescopic component 4. The telescopic end of the first telescopic component 4 pushes or pulls the front end of the support plate 2, causing the support plate 2 to rotate around the central axis 11, thereby adjusting the tilt angle of the facial support component relative to the base plate 1. At the same time, the fixed end of the first telescopic component 4 slides synchronously within the groove of the base plate 1 via the slider 13 to accommodate the displacement caused by changes in the angle of the support plate 2.

[0046] The patient lies prone on the bed, placing their face between a pair of facial support components, with their cheeks resting against the facial support pads 3 on the side support plates 2, and their forehead and chin naturally suspended or lightly touching the upper and lower edges of the facial support pads 3. The patient's chest rests prone on the main airbag pad 8. When the main airbag pad 8 is compressed, the internal air is forced into the side airbag pads 9, which inflate and conform to the sides of the patient's torso, forming passive lateral fixation. The patient's arms are placed naturally on the side arm supports 10. The length or opening angle of the arm supports 10 can be adjusted by rotating the internal threaded cylinders of the arm supports 10 as needed. The restraint strap 7 is wrapped around the back of the patient's head and tightened appropriately to ensure a stable fit between the face and the facial support pads 3. If an outer cover 16 is required, it can be placed over the device.

[0047] During use, patients can fine-tune the tilt angle or support spacing at any time using the control buttons according to their own feelings. The display screen of the intelligent control unit 6 shows the current angle and spacing parameters in real time, and the intelligent speaker can play music or audio content to help patients relax, distract themselves, and alleviate the boredom and discomfort of lying prone for a long time.

[0048] Example 2: As Figures 5 to 7 As shown, the prone positioning device of this embodiment, compared with embodiment 1, adds an inflation assembly between a pair of arm supports 10. The inflation assembly includes a groove 18, an inflation outer cylinder 19, and a piston rod assembly 20. The groove 18 is fixedly connected to the side of the arm support 10 and rotates synchronously with the arm support 10. The inflation outer cylinder 19 is fixedly connected to the base plate 1, and its interior has an air chamber that slides and seals with the piston of the piston rod assembly 20. Both the inflation outer cylinder 19 and the air guide pipe are connected to a one-way gas valve to control the unidirectional flow of gas. The one-way gas valve connected to the air inlet end of the inflation outer cylinder 19 controls the gas to flow unidirectionally only from the outside to the inside of the inflation outer cylinder 19, and the one-way gas valve connected to the air guide pipe controls the gas to flow unidirectionally only from the inflation outer cylinder 19 to the inside of the main airbag pad 8 and / or the branch airbag pad 9. The main airbag pad 8 and / or the branch airbag pad 9 are connected to the air outlet end of the inflation outer cylinder 19 through the air guide pipe. The outer end of the operating rod of the piston rod assembly 20 is slidably connected to the groove 18. Specifically, the groove 18 has a strip-shaped slot extending along its length, and the outer end of the operating rod has a slider embedded in the strip-shaped slot. When the arm support 10 swings relative to the base plate 1, the groove 18 can drive the operating rod to reciprocate along the axial direction of the inflation outer cylinder 19. The piston of the piston rod assembly 20 is slidably and sealed to the inner wall of the inflation outer cylinder 19, and the piston forms a pumping action when it reciprocates in the inflation outer cylinder 19.

[0049] In the prone positioning device of this embodiment, when the patient's arm is placed on the arm support 10, and due to prolonged prone positioning, slight periodic swinging occurs, or the patient adjusts their posture or makes slight active movements, the arm support 10 swings periodically relative to the base plate 1 around its rotational connection point with the base plate 1. The arm support 10 drives the groove 18 of the inflation assembly to swing synchronously. The groove 18 drives the operating rod of the piston rod assembly 20 to slide back and forth along the axial direction of the inflation outer cylinder 19 through its strip-shaped slot, thereby driving the piston to reciprocate within the air chamber of the inflation outer cylinder 19.

[0050] When the piston moves away from the outlet, a negative pressure is created inside the inflation cylinder 19, drawing outside air into the air chamber through the one-way valve at the inlet end of the inflation cylinder 19. When the piston moves towards the outlet, the air in the air chamber is compressed and forced into the main airbag 8 and / or the ventilator 9 through the one-way valve on the air guide tube. This cycle repeats continuously, converting the unavoidable slight movements of the patient's arms during prolonged prone positions into kinetic energy to replenish the gas supply to the position-maintaining components. This keeps the main airbag 8 and ventilator 9 fully supported, automatically maintaining the stability and comfort of the patient's position without the need for additional power or manual operation.

[0051] The shape, structure, connection method, usage method, and effect of the remaining components in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0052] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
