Description

Technical Field

[0001] This invention relates to the field of gynecological examination technology, and in particular to a gynecological examination device that integrates position adjustment, privacy protection, and splash prevention. Background Technology

[0002] Gynecological examinations are an important medical procedure for maintaining women's health. However, traditional examination beds have limited functionality and significant shortcomings in terms of protection, humanization, and safety. Current examination processes rely primarily on manual operation and verbal instructions from medical staff, which is not only inefficient but also poses multiple risks, including cross-infection, patient discomfort, and privacy breaches.

[0003] In gynecological surgeries and examinations (such as hysteroscopy, LEEP, biopsy, etc.), the use of high-frequency equipment easily generates aerosols, and rinsing and disinfection steps often involve accidental splashing of patient bodily fluids and secretions. These contaminants are a major route of exposure for healthcare workers to bloodborne pathogens such as HIV, HPV, and HBV, posing a serious occupational exposure risk. Traditional examinations require patients to move their bodies to a suitable position on a narrow examination bed (e.g., moving their buttocks to the foot of the bed), often requiring repeated verbal guidance or assistance from healthcare staff. This not only increases the workload of healthcare workers and prolongs preparation time but may also exacerbate patients' tension and discomfort due to embarrassment and repeated movements. The exposed nature of gynecological examinations easily triggers feelings of shame and psychological stress in patients. In traditional open examination environments, with only a curtain for cover, patients still feel exposed and helpless while lying down and during the examination. This psychological discomfort may lead to muscle tension, non-cooperation, and affect the accuracy and smooth progress of the examination. The disposable sterile drapes used during examinations are crucial for maintaining a sterile operating area and preventing cross-infection. However, patient movement or careless handling by medical staff can easily cause the drapes to shift, wrinkle, or even slip off, exposing non-sterile areas, violating aseptic principles, and posing a potential risk of infection. This is especially true during painless examinations or surgeries, when patients are sedated or anesthetized, their consciousness is impaired, and their bodily control is reduced, creating a potential risk of falling from the sides of the narrow examination table. Even for conscious patients, discomfort or tension during the examination can lead to accidental slippage, posing a safety hazard.

[0004] Chinese patent application CN 118576444 B discloses a protective device for gynecological examinations, including a gynecological examination recliner. The recliner is equipped with a fixing plate, a fixing frame, a hysteroscopy support, a hysteroscope, a hysteroscopy tube, a controller, a drive assembly, and a protective mechanism. The fixing plate is fixed to the recliner via the support and is located on one side of the recliner. The fixing frame is fixed to the fixing plate, and the hysteroscopy support and controller are both fixed to the fixing frame. This invention, by incorporating protective components, allows the face shield to cover the medical staff's face during the examination, preventing the distending fluid from splashing onto their face due to the pressure difference between the inside and outside of the patient's body, thus protecting the medical staff.

[0005] However, this application can only protect medical staff, not patients or their privacy. It also cannot automatically adjust the patient's position, so when patients use the examination chair provided by this application, they rely on manual operation and verbal instructions from medical staff. This is not only inefficient, but also poses multiple risks such as cross-infection, patient discomfort, and privacy leaks. Summary of the Invention

[0006] To address the aforementioned problems, this invention aims to provide a gynecological examination device that integrates position adjustment, privacy protection, and splash prevention. It not only protects medical personnel but also protects patients and their privacy. Furthermore, it automatically adjusts the patient's position, allowing patients to use the examination chair without relying on manual operation or verbal instructions from medical staff. This method is highly efficient and eliminates multiple risks such as cross-infection, patient discomfort, and privacy leaks.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A gynecological examination device integrating position adjustment, privacy protection, and splash prevention, comprising an examination bed body, which includes a base and a bed frame, characterized in that it further includes: An adaptive body position limiting module is located on the top surface of the sitting position on the bed and is configured to adaptively adjust the sitting position by driving the fluid dynamics on the bed through the body's own weight. The dual-sided foldable automatic unfolding module is symmetrically located on the left and right sides of the bed. It is configured to unfold freely upwards while the sitting position is adaptively adjusted by the fluid driven by its own weight, forming a semi-enclosed privacy protection area with openings on the left, right, top and front sides. The multi-angle anti-splash module is located at the end of the bed and is movably connected to the end of the bed. It is configured to simultaneously block pollutants from multiple viewing angles.

[0008] Furthermore, the adaptive posture constraint module includes: The pouch assembly is matched to the parts of the human body that need support, and is evenly distributed in the sitting position of the bed. The middle part is reserved for the buttocks, and the inside is filled with fluid. The buttock recess, located in the buttock area, includes a pair of cushion bodies that can sink from top to bottom and a molded support body placed in the cushion body and conforming to the human buttocks.

[0009] Furthermore, the pouch assembly includes: The leg-side pouches are equipped with towel-holding slots on their inner top surfaces; The buttock sac is positioned both in front of and behind the buttock reserved area, and confines the seat cushion within this area.

[0010] Furthermore, the molded support includes: A truncated cone, having a pair of recesses on it that correspond to the shape of a human buttocks; and, The shape variant is configured as a first shape variant in the horizontal direction and a second shape variant in the vertical direction; The first shape-shifting variant is integrated with the pouch assembly. By using its own weight to drive fluid to adaptively adjust the sitting position, it causes the first shape-shifting variant and the longitudinal second shape-shifting variant to deform and wrap around the side of the human body.

[0011] Furthermore, each side of the foldable, automatically unfolding module includes: The pusher is configured as a combination of a slot and a long rod that connects to the towel docking clamping slot; The folding curtain is placed at the upper end of the slot of the pusher, and the folding curtain is opened instantly by the pushing force of the pusher.

[0012] Furthermore, it also includes: The dual-axis combined automatic drape changing module is installed at the front and rear ends of the bed bottom, and automatically changes the sterile drape through dual-axis transmission.

[0013] Furthermore, the dual-axis combined automatic order change module includes: A transition extension device, the bottom of which is connected to the bed body; The drape insert block is connected to the top of the transition extension device and matches the drape docking and clamping groove. It controls the engagement of the drape insert block with the drape docking and clamping groove by its own weight, thus fitting the sterile drape between the two.

[0014] Furthermore, the multi-angle splash protection module includes: The base plate is configured as a pull-out structure that can be stored at the bottom of the bed. The splash guard is hinged to the base plate and is hollow with a cleaner in the center. The observation window is positioned on the splash guard above the cleaner, and the area is fitted with transparent glass.

[0015] Furthermore, the cleaner includes: The elastic cavity is configured as a retractable cylindrical structure and filled with a cleaning substance. A cavity reset component is disposed on the outer periphery of the cylindrical surface of an elastic cavity, and has multiple sets of spaced connecting blocks and a reset spring.

[0016] Furthermore, the observation window is perforated, and its inner wall has small spray holes that communicate with the anti-splash plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This solution constructs a dynamic protection system through the coupling of three technologies: adjustable-angle protection, fluid-adaptive body positioning, and linked shielding. The multi-angle anti-splash module combines a 180° rotatable anti-splash plate with a flexible defogging observation window, working in conjunction with a dual-axis linked automatic draping module to simultaneously achieve droplet blocking and aseptic maintenance. The fluid-filled sac assembly automatically adjusts the patient's position through pressure feedback, allowing the patient to autonomously and precisely adjust their sitting posture using their own weight, while the folding curtain simultaneously addresses the issues of privacy exposure and patient falls from the bed.

[0018] Specifically: The multi-angle splash guard module combines a high-temperature resistant polycarbonate base plate with an elastic splash guard plate, achieving 180° angle adjustment via an angle adjustment component to form a closed protective barrier. The cavity reset component contains a built-in defogging agent that automatically cleans the observation window, effectively blocking bodily fluid splashes, aerosols, and other contaminants, ensuring safe use.

[0019] The dual-axis automatic drape-changing module achieves automatic laying and replacement of sterile drapes through the linkage of two rollers (No. 1 and No. 2). Combined with the mechanical fixation of the clamping components, it avoids the drape displacement problems caused by traditional clamps. The continuity of the sterile area is significantly improved, reducing the frequency of intervention by medical staff to repeatedly adjust the drapes.

[0020] The adaptive positioning module's leg-side pouches automatically inflate and rise when the patient's buttocks are under pressure, forming a cushioning layer to prevent falls. A heated interlayer maintains the water temperature of the pouch assembly between 38℃ and 42℃, enhancing patient comfort. The coordinated design of the seat cushion, truncated cone, recessed groove, and deformation mechanism ensures the patient sits in the correct position from the start, avoiding repeated adjustments by medical staff and significantly reducing discomfort caused by muscle tension during examinations. Simultaneously, the bilaterally foldable, automatically deployable modules automatically unfold as the leg-side pouches rise, forming a bilateral physical barrier and resolving exposure anxiety issues associated with traditional curtains.

[0041] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Existing gynecological examination beds have the following drawbacks in use: When healthcare workers are exposed to bodily fluid splashes or aerosol generation, they can only rely on personal protective equipment (PPE) such as masks, face shields, and gloves. These PPEs have blind spots (such as the neck and chest) and are not comfortable, failing to provide comprehensive and effective isolation, thus exposing healthcare workers to biosafety risks for extended periods.

[0043] The patient's positioning relies entirely on verbal instructions and manual adjustments from medical staff (such as "sit down a little"), a process that is repetitive, costly in terms of communication, and time-consuming. Meanwhile, the sterile drapes are often secured using traditional mechanical clips or simply laid out, making them prone to shifting during patient movement or procedures. This necessitates repeated adjustments, disrupting the continuity of the sterile area, increasing operation time, and requiring unnecessary intervention.

[0044] With only a simple curtain for privacy, patients' bodies are still exposed to varying degrees when lying down, moving, and undergoing examinations, easily leading to strong feelings of shame and anxiety. The examination beds are generally narrow, with no effective side protection. For sedated or weak patients, there is a risk of falling; for conscious patients, the fear of falling causes muscle tension, which exacerbates the discomfort of the examination. The cold metal bed, hard footrests and handrails, and the awkwardness of needing to adjust one's own position all contribute to making the examination process daunting.

[0045] While there are some improved single-function products on the market, such as individual towel clips or adjustable side panels, these are fragmented and non-integrated solutions. Using multiple different brands of equipment simultaneously can lead to a chaotic examination bed layout, inconvenient operation, and even mutual interference, failing to optimize the overall examination process.

[0046] To resolve the above issues, please refer to Figures 1-19 This application discloses a gynecological examination device that integrates group position adjustment, privacy protection and splash prevention, including an examination bed body, which includes a base 1 and a bed body 2, and also includes: an adaptive body position limiting module, which is located on the top surface of the sitting position on the bed body 2 and is configured to adaptively adjust the sitting position by the fluid dynamics of the fluid on the bed body 2 driven by its own weight. The dual-sided foldable automatic unfolding module is symmetrically located on the left and right sides of the bed 2. It is configured to unfold freely upwards while the sitting position is adaptively adjusted by the fluid driven by its own weight, forming a semi-enclosed privacy protection area with openings on the left, right, top and front sides. A multi-angle anti-splash module, located at the end of bed 2 and movably connected to the end of bed 2, is configured to simultaneously block contaminants from multiple viewing angles. This effectively blocks droplets, bodily fluid splashes, and aerosols during procedures, fundamentally reducing the occupational exposure risk for healthcare workers.

[0047] The examination bed body 2 is configured for sitting and lying positions. The total length of bed body 2 is between 1900-2100 mm to accommodate patients of different heights. The bed surface width is 600-650 mm; too narrow a width may cause patient tension, while too wide a width may affect the doctor's operation. The sitting and lying positions are adjustable, with an adjustment range of 700-850 mm to accommodate switching between sitting and lying examination modes. The specific connection method, materials, and dimensions of the base 1, bed body 2, and sitting and lying positions can refer to the existing CHS-E1000 model gynecological examination bed. This application does not improve the connection relationship between the sitting and lying positions of the examination bed body, and will not be elaborated further here. Two leg supports 9 are hinged to the left and right sides of the sitting position, and two footrests 10 are welded to the left and right sides of the base 1 to facilitate the patient's smooth entry into bed body 2.

[0048] To enable patients to independently achieve precise sitting posture using their own body weight, avoiding the problems of repeated processes, high communication costs, and time-consuming and labor-intensive adjustments that rely on verbal guidance and manual assistance from medical staff during the patient's sitting posture adjustment process, this application includes an adaptive body position limiting module, specifically including: a pouch assembly that matches the body parts that need support and is evenly distributed in the sitting position of the bed 2, with a reserved area for the buttocks in the middle, and fluid is installed inside it; a buttock recess body, which is provided in the reserved area for the buttocks and includes a pair of cushion bodies 12 that can be recessed from top to bottom and a molded support body placed in the cushion body 12 that can match the human buttocks.

[0049] To heat the fluid within the cuff assembly, this application also includes a heating interlayer located inside the bed 2 adjacent to the cuff assembly. This heating interlayer is specifically a heating element 32, which heats the water injected into the cuff, enhancing patient comfort. After the examination, the heating element 32 is activated to dry and sterilize the work surface at high temperature.

[0050] The pouch assembly includes: a leg-side pouch body 14, the top surface of which is provided with a towel-and-sheet docking and clamping groove 23; the towel-and-sheet docking and clamping groove 23 is bonded and fixedly connected to the top surface of the leg-side pouch body 14, and the bottom of the towel-and-sheet docking and clamping groove 23 is also hinged to the bottom surface of the leg-side pouch body 14 through two movable rods 35. The two movable rods 35 limit the expansion height of the leg-side pouch body 14 and support the shape of the leg-side pouch body 14 to prevent the leg-side pouch body 14 from deforming during the water injection expansion process.

[0051] Two gluteal pouches 30 are provided at the front and back of the reserved area of ​​the buttocks, and confine the seat cushion 12 within this area. The number of gluteal pouches 30 is two, and they are respectively provided on the front and back sides of the seat cushion 12, forming a semi-enclosed structure for the seat cushion 12. The seat cushion 12 is connected to the gluteal pouches 30. When the patient sits on the seat cushion 12, the fluid in the seat cushion 12 is squeezed into the two gluteal pouches 30 connected to it by the patient's own weight, and then flows into the leg pouches 14 connected to the two gluteal pouches 30. Furthermore, there are two leg-side pouches 14, and the two leg-side pouches 14 and the two buttock-side pouches 30 are connected in a one-to-one correspondence. That is to say, one leg-side pouch 14 is only connected to one buttock-side pouch 30. This arrangement ensures that the amount of fluid flowing into the two leg-side pouches 14 is basically the same, so that the height of the two leg-side pouches 14 is basically the same.

[0052] Furthermore, water is preferred as the fluid in the bag assembly due to its good fluidity, biocompatibility, and ease of access. Water can be supplied to the bag assembly via an external water source and a water inlet pipe connected to any of the bags, causing each bag to inflate and form a water-filled sac for flexible support of the patient. A drain pipe is also connected to one of the bags in the assembly to facilitate the drainage of used water. Since all the bags in the assembly are interconnected, the positions of the water inlet and drain pipes can be adjusted according to the specific circumstances and are not fixed. Furthermore, since the operating principle of the bag assembly is the same, the two armrest-side bag bodies 6 and the two leg-side bag bodies 14 are used as examples for explanation. The two armrest-side bag bodies 6 are connected to the back bag located between the two armrest-side bag bodies 6 through connecting pipes 29. The two leg-side bag bodies 14 are connected to the buttock-side bag bodies 30 located between the two leg-side bag bodies 14 through connecting pipes 29. When the patient lies on the examination bed, the patient's own weight can quickly squeeze the water in the back bag and the buttock-side bag body 30 into the two armrest-side bag bodies 6 and the leg-side bag bodies 14. This causes the armrest-side bag bodies 6 and the leg-side bag bodies 14 to rise due to the increased water volume, thereby enabling the armrest-side bag bodies 6 and the leg-side bag bodies 14 to support and protect the patient's hands and legs.

[0053] It should be noted that the reclining position of the bed 2 in this application also includes a reclining pouch assembly, which includes an armrest-side pouch 6 and a back pouch, and the armrest-side pouch 6 and the back pouch are connected by a connecting tube 29. The usage method and principle of the reclining pouch assembly are the same as those of the pouch assembly in the sitting position. Since the usage method and principle of the pouch assembly in the sitting position have been explained in detail above, the reclining pouch assembly will not be described in detail here.

[0054] All the pouch assemblies in this application are made of silicone or latex and are sewn or bonded to the upper surface of the bed 2. Taking the sitting pouch assembly as an example, its dimensions and water volume are explained as follows: If the length of the leg-side pouch 14 in its unfilled state is 450mm, the width is 160mm, and the height is 30mm, after filling it with approximately 5.04 liters of water, its height will become 100mm. That is to say, in the unused state, 5.04 liters of water need to be poured into the pouch assembly. Then, when the patient sits on the seat cushion 12, all the water in the seat cushion 12 and the surrounding buttock-side pouches 30 is squeezed into the leg-side pouch 14, thereby increasing the height of the leg-side pouch 14 to 100mm. The calculation principle for the water volume of the lying-down pouch assembly is the same as that of the sitting pouch assembly. The water volume can be adjusted according to the dimensions of each pouch in the specific lying-down pouch assembly, which will not be elaborated here.

[0055] The molded support includes: a frustum 13 with a pair of recessed grooves 37 that match the buttocks of a human body; and a deformable body 31 configured as a first deformable body 311 in the horizontal direction and a second deformable body 312 in the vertical direction; wherein, the first deformable body 311 is integrally set with the frustum 13, and while the sitting position is adaptively adjusted by the fluid driven by its own weight, the first deformable body 311 and the second deformable body 312 in the vertical direction are deformed to wrap around the side of the human body.

[0056] The truncated cone 13 is a truncated cone-shaped structure with a diameter of 400mm and a thickness of 5cm. It is made of hard plastic. Two deformable parts 31 are symmetrically provided on the left and right sides of the truncated cone 13. The two deformable parts 31 are adapted to the edges of the truncated cone 13 and are bonded to the two sides of the truncated cone 13.

[0057] More specifically, both the first deformable shape 311 and the second deformable shape 312 are silicone sheets with deformability. The first deformable shape 311 has a length of 400 mm, a width of 400 mm, and a thickness of 20 mm. The second deformable shape 312 has a length of 400 mm, a width of 200 mm, and a thickness of 20 mm. The cross-sectional view of the combined state of the two is L-shaped.

[0058] Here, we will use the left-side variant 31 as an example: The top of the first variant 311 is level with the top of the towel-attachment clamping groove 23. Two horizontal bars 38 pass through the level part of the two to fix them, so that when the towel-attachment clamping groove 23 rises with the leg-side pouch body 14, the first variant 311 will also rise. Since the second variant is integrated with the truncated cone 13, it will collapse downward under the weight of the patient, while the first variant 311 will rise with the towel-attachment clamping groove 23. This will increase the angle between the originally vertical first variant 311 and the second variant 312, so that when the patient sits on the cushion body 12 above the truncated cone 13, it will form a concave shape in the middle and rising on both sides, positioning the patient's buttocks in the middle, which can help the patient sit in the correct position in one go and avoid repeated movement reminded by medical staff.

[0059] Each side of the foldable automatic unfolding module includes: a pusher, which is configured as a combination of a slot 33 and a long rod 34 connected to the towel docking clamping slot 23; and a folding curtain 7, which is placed on the upper end of the slot 33 of the pusher and is opened instantly by the pusher's thrust.

[0060] Specifically, the pusher consists of a welded slot 33 and a long rod 34. The slot 33 is located below the folding curtain 7, and the free end of the long rod 34 passes through and is fixedly connected to the towel-and-sheet clamping slot 23. When the towel-and-sheet clamping slot 23 rises with the leg-side pouch body 14, the long rod 34 and the slot 33 also rise, causing the folding curtain 7 above the slot 33 to open instantly with the push. Preferably, the folding curtains 7 on both sides of the bed 2 can be wrapped with a disposable film after unfolding to ensure a sterile environment, and can be collected and disposed of after use.

[0061] More specifically, the folding curtain 7 is connected to the pusher via a linkage assembly. In other words, the pusher's slot 33 is actually engaged below the linkage assembly, thus enabling the folding curtain to be opened. The linkage assembly includes a multi-link, configured as multiple cross-hinged connecting rods 8. The hinges of the multiple connecting rods 8 are connected to the folding curtain 7 via a fixed shaft 11. The bottom center of the multi-link is connected to the pusher, and the bottom sides are fixed to the bed frame 2 via limiting rods 36. The multi-link consists of multiple hinged connecting rods 8. When the pusher rises with the towel clamping slot 23, it pulls the hinges of the multi-link, thereby stretching the multi-link. The folding curtain 7 is made of dark-colored waterproof fabric, which can protect the patient's privacy and is easy to clean. By connecting the hinge of the multi-link rod to the folding curtain 7 through the fixed shaft 11, the multi-link rod can stretch the folding curtain 7 together when it is stretched, so that the folding curtain 7 can be unfolded from being stacked, increasing the area and providing privacy for the patient, as well as preventing the patient from falling out of bed.

[0062] To ensure the sterility of the operating area, reduce the possibility of cross-infection between patients, and achieve comprehensive safety protection for both medical staff and patients, this application also includes a dual-axis combined automatic drape changing module, which is installed at the front and rear ends of the bottom of the bed 2 and automatically changes the sterile drape 5 through dual-axis transmission.

[0063] The aforementioned dual shafts are specifically: a first roller 3, located below the front end of the bed body 2, connected to the bed body 2 via two fixing rods 15, and having one end with a sterile drape 5 wound up; a second roller 4, located below the rear end of the bed body 2, connected to the bed body 2 via two fixing rods 15, and having the other end with a sterile drape 5 wound up; and a second drive motor 28, connected to the second roller 4.

[0064] A new sterile drape 5 is wound onto the first roller 3. Then, the end of the sterile drape 5 is pulled and laid on the upper surface of the bed 2. The end of the sterile drape 5 is then wound onto the second roller 4, so that sterile drapes are wound on the first roller 3 and the second roller 4. During this process, the sterile drape 5 will be laid on the upper surface of the bed 2 to protect the patient. When the sterile drape 5 is used up, the second drive motor 28, which is fixedly connected to the second roller 4, is started. The second drive motor 28 drives the second roller 4 to rotate. The kinetic energy is then transferred from the second roller 4 to the first roller 3 through the sterile drape 5, causing the first roller 3 to rotate. This causes the second roller 4 to roll up the used sterile drape 5. During the rolling process, a new sterile drape 5 will be laid on the upper surface of the bed 2 for the next patient to use.

[0065] The dual-axis combined automatic sheet changing module includes: a transition extension device, the bottom of which is connected to the bed body 2; and a sheet fitting block 24, which is connected to the top of the transition extension device and matches the sheet docking clamping groove 23. By driving the fluid direction by its own weight, the sheet fitting block 24 is controlled to engage with the sheet docking clamping groove 23, and the sterile sheet 5 is fitted between the two.

[0066] The transition extension device is configured as a connecting shaft 25 fixed to the side of the bed body 2. One end of the connecting shaft 25 is welded to the side of the bed body 2, and the other end is welded to the towel fitting block 24. When the leg-side pouch body 14 rises, the towel docking clamping groove 23 connected to it also rises. Since the outer diameter of the towel fitting block 24 matches the inner diameter of the towel docking clamping groove 23, when the towel docking clamping groove 23 continues to rise, the towel docking clamping groove 23 and the towel fitting block 24 will fit together across the upper surface of the leg-side pouch body 14. Figure 10-12 As shown, this will cause the sterile drape 5 located between the sterile drape 5 docking clamping groove 23 and the drape interlocking block 24 to be clamped in the interlocking gap between the drape docking clamping groove 23 and the drape interlocking block 24, thus forming a stable clamping of the sterile drape 5.

[0067] The multi-angle anti-splash module includes: a base plate 16, configured as a pull-out structure that can be stored at the bottom of the bed 2; an anti-splash plate 17, hinged to the base plate 16, which is hollow and has a cleaner in the center; and an observation window 21, which is located on the anti-splash plate 17 above the cleaner and has transparent glass installed in the area.

[0068] The cleaner includes: an elastic cavity 18 configured as a retractable cylindrical structure filled with cleaning material; a cavity reset member disposed on the outer periphery of the elastic cavity cylinder, having multiple sets of spaced connecting blocks 27 and a reset spring 20. The observation window 21 is perforated, and its inner wall has spray holes 22 that communicate with the anti-splash plate 17.

[0069] The cleaning agent is preferably a defogging agent. An input hole 26 is provided on the outer surface of the elastic cavity 18, and a plug is also provided on the input hole 26. The defogging agent is installed in the elastic cavity 18 through the input hole 26. The interior of the elastic cavity is connected to the bottom of the observation window 21 through multiple spray holes 22. By pressing the elastic cavity 18, the defogging agent inside the elastic cavity 18 can be sprayed onto the two observation surfaces of the observation window 21 through the multiple spray holes 22 to defog, which is convenient for medical staff to observe the patient's examination area. After defogging is completed, when the elastic cavity 18 is not pressed, the return spring 20 located outside the elastic cavity 18 will automatically drive the elastic cavity 18 to return to its original position for the next use.

[0070] In order to achieve multi-angle splash protection, this application also provides an angle adjustment component between the splash protection plate 17 and the base plate 16. Specifically, the angle adjustment component includes: two limiting members, which are spaced apart above the base plate 16 and connected to the base plate 16; and an adjusting member, which passes through the two limiting members and is movably connected to the two limiting members.

[0071] Both limiting components are fixed blocks bonded to the upper surface of the base plate 16. Each fixed block has an opening at its center to facilitate the insertion of the adjusting component. The adjusting component is a drive motor 19 with its output end inserted into the two fixed blocks. By starting the drive motor 19, the drive motor 19 drives the anti-splash plate 17 connected to it to rotate, thereby adjusting the angle of the anti-splash plate 17. The anti-splash plate 17 can be rotated 180° according to the needs of medical personnel for examination, until it is rotated to the required position.

[0072] It should be noted that both the base plate 16 and the anti-splash plate 17 are made of high-temperature resistant plastics, such as polycarbonate, and can be reused multiple times. After each use, they should be sterilized by high-temperature and high-pressure steam at a temperature of 121℃-134℃ for 15-30 minutes.

[0073] Preferably, in order to allow the multi-angle anti-splash module to be stored after use without hindering other actions of medical staff or patients, this application also provides a storage cavity inside the bed body 2. Slide rails are symmetrically arranged on both sides of the storage cavity, and sliders are provided on both sides of the base plate 16. The sliders are fitted into the slide rails. When using the multi-angle anti-splash module, the base plate 16 is pulled out of the storage cavity, and then the anti-splash plate 17 is rotated to the required angle for use. After the multi-angle anti-splash module is used up, the anti-splash plate 17 can be rotated from a position perpendicular to the base plate 16 to a position parallel to the base plate 16. Then, the base plate 16 is pushed into the storage cavity inside the bed body 2 via the sliders and slide rails to store the base plate 16 and the anti-splash plate 17, facilitating other operations by medical staff.

[0074] Example 1 The workflow of gynecological examination protective equipment is as follows: Once the patient enters the examination room, the sterile area is first established using the dual-axis combined automatic drape-changing module: after starting the second drive motor 28, the first roller 3 releases the pre-wound sterile drape 5, which lays flat along the surface of the examination bed and automatically extends to the second roller 4. This ensures that the sterile drape 5 completely covers the patient's contact area. After the sterile drape 5 is laid out, medical staff guide the patient to sit smoothly on the bed 2 using the side footrest 10. At this time, the multi-angle anti-splash module is in a retracted state, and the base plate 16 is completely retracted into the storage cavity inside the examination bed body, providing the patient with an unobstructed initial position. When the patient's buttocks come into contact with the silicone seat cushion 12, its own weight triggers the linkage mechanism of the pouch assembly: the water in the seat cushion 12 is squeezed to the leg pouch 14, causing the leg support to naturally rise to a comfortable height. At the same time, the deformable shapes 31 on both sides of the truncated cone 13 form ramps to guide the patient to position themselves in the center. This process does not require verbal guidance, and the patient can independently complete the precise adjustment of their sitting posture, significantly reducing the embarrassment of repeated movement during traditional examinations.

[0075] As the patient adjusts their sitting position, the clamping assembly immediately activates: the deformable part 31 lifts the drape-attaching clamping groove 23 via the movable rod 35, forming a mechanical engagement with the side drape interlocking block 24, firmly fixing the sterile drape 5 to both sides of the bed 2. This three-point fixing method prevents the sterile drape 5 from moving due to patient displacement during the examination. If the patient moves slightly during the examination, the silicone deformable part 31 will adapt its deformation, guiding the patient back to the initial position through the ramp structure, avoiding wrinkles in the sterile drape 5. When the operation is finished and the drape needs to be changed, the second scroll 4 rotates in reverse, and the used sterile drape 5 is automatically wound onto the second scroll 4, while a new sterile drape 5 is simultaneously unrolled from the first scroll 3, ensuring that the next patient always comes into contact with an uncontaminated area.

[0076] It is worth noting that the heating layer has been pre-maintained at the water temperature of the bag assembly at 38-42℃ to avoid the cold touch of the metal bed, and the connection design between the back bag and the armrest side bag 6 ensures that the patient can get even support when lying down.

[0077] Then, an inspection can be performed. After the inspection, the equipment will initiate the recovery and disinfection procedure: the heating interlayer will switch to high-temperature disinfection mode, and the surface of bed 2 will be steam-sterilized at 121℃-134℃ for 15-30 minutes to thoroughly kill pathogenic microorganisms. Simultaneously, the drain pipe will be opened to completely drain the water from the bag assembly, preventing residual liquid from breeding bacteria. The disposable sterile drape 5 can be manually removed by medical staff for medical waste disposal.

[0078] Example 2 Based on Embodiment 1, this application also includes a multi-angle anti-splash module. After the patient's position is adjusted, the multi-angle anti-splash module automatically unfolds to form a closed-loop protective barrier. Medical personnel control the base plate 16 to move to the operating area via a slider, and the first drive motor 19 drives the protective component to rotate to the optimal angle, so that the high-temperature resistant polycarbonate anti-splash plate 17 completely covers the patient's upper body. At this time, the elastic cavity is in a standby state, and its external return spring 20 and locking block ensure structural stability. When the observation window 21 fogs up due to temperature difference, medical personnel gently press the elastic cavity, and the internal defogging agent is evenly sprayed on both sides of the glass of the observation window 21 through multiple spray holes 22 to achieve rapid defogging. The automatic reset device of the return spring 20 facilitates continuous operation. The three-dimensional barrier formed by the protective component and the base plate 16 can block more than 90% of splashes, while the high-temperature sterilization design of the anti-splash plate 17 ensures safety for repeated use. For operations requiring observation from multiple angles, the angle adjustment component allows the splash guard 17 to rotate 180°, ensuring that medical staff always have a clear view without blind spots, while the patient remains physically isolated throughout the process, effectively alleviating exposure anxiety.

[0079] Example 3 Based on Embodiment 1, this application also provides a double-sided foldable automatic unfolding module to prevent patients from falling out of bed and to protect patients' privacy. When the towel and sheet docking clamping groove 23 rises with the leg-side pouch body 14, the long rod 34 and the slot 33 will also rise, thereby causing the folding curtain 7 located above the slot 33 to open instantly with the thrust.
