Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a laminar flow bed cover and a laminar flow bed. Background Technology

[0002] In clinical practice, patients in hematology and oncology departments often have low immune function due to the disease itself or treatment methods (such as chemotherapy and radiotherapy), while burn patients have damaged skin barriers, making them susceptible to invasion by dust, microorganisms, and other pollutants in the external environment, leading to infectious complications that seriously affect treatment outcomes and recovery. To reduce such infection risks, laminar flow beds, as a medical device that can create localized clean spaces, have been widely used in these departments.

[0003] The core function of a laminar flow bed is to filter and purify the air in a specific area through an air purification system, and then deliver it into that area in a specific airflow pattern while maintaining a positive pressure environment within the area. This prevents dust particles, microorganisms, and other contaminants from the outside space from entering, ensuring the cleanliness of the air within the area. As a key component in constructing a clean space, the laminar flow bed hood's structural design directly affects the airtightness, ease of use, and patient comfort of the clean space.

[0004] Currently, while laminar flow mattresses on the market can initially create a protective space in actual use, there is still room for improvement in terms of structural flexibility and functional adaptability. Therefore, we propose a laminar flow mattress.

[0005] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Utility Model Content

[0006] The purpose of this invention is to provide a laminar flow hood and a laminar flow bed, so as to optimize the structural design of the laminar flow hood, improve the flexibility and convenience of use while ensuring the airtightness and stability of the clean space, and better adapt to clinical medical needs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A laminar flow bed cover, comprising: frame; A shielding assembly, wherein multiple shielding assemblies are provided, and the multiple shielding assemblies are respectively installed on each side of the frame and enclose to form an inner cavity for accommodating the patient; A clean air supply device is installed above the frame and is used to supply clean air into the inner cavity of the bed cover. Wherein, at least one of the shielding components includes a rigid shielding member and a flexible shielding member distributed in the left-right direction, and both the rigid shielding member and the flexible shielding member are connected to the frame. The rigid barrier has a through slot for passing items, and a sealing plate is hinged to the rigid barrier for opening and closing the through slot.

[0008] Furthermore, the sealing plate is located on the side of the rigid barrier facing the inner cavity of the mattress cover, and the lower side of the sealing plate is hinged to the rigid barrier via a hinge. The upper end face of the hinge forms a support portion, which is used to support the sealing plate after the sealing plate is flipped open backward, so as to keep the sealing plate in a horizontal state.

[0009] Furthermore, it also includes a pull cord and a limiting member, wherein the rigid blocking member has a wire hole located above the through groove; One end of the pull cord is connected to the end of the sealing plate away from the hinge, and the other end passes through the wire hole from the inner cavity of the bed cover and is connected to the limiting member; the limiting member is used to abut against the outer side of the rigid blocking member when the sealing plate is kept in a horizontal state, so as to support the sealing plate by the pull cord.

[0010] Furthermore, there are two sets of pull ropes and wire holes, and the two sets of pull ropes and wire holes are distributed on both sides of the sealing plate in the left and right directions respectively; the limiting member is a horizontally extending rod shape, and the ends of the two sets of pull ropes away from the sealing plate are connected to the limiting member.

[0011] Furthermore, both ends of the limiting member are provided with magnetic components, and the outer side of the rigid blocking member is provided with a magnetic attraction component corresponding to the position of the magnetic component. The magnetic component and the magnetic attraction component can be magnetically attracted to each other to fix the relative position of the limiting member and the rigid blocking member.

[0012] Furthermore, the outer diameter of the magnetic component is larger than the outer diameter of the limiting member rod, which is used to create a gap between the limiting member rod and the rigid barrier when the magnetic component abuts against the rigid barrier. The magnetic component is hexagonal in shape, and one of its planes is used to adhere and attract with the magnetic component.

[0013] Furthermore, the flexible shielding component is provided in multiple pieces, and all the flexible shielding components are arranged vertically along the longitudinal direction; adjacent flexible shielding components can be magnetically attracted to each other, and the outermost flexible shielding component can be magnetically attracted to the rigid shielding component or the frame. The flexible shielding component can be reset under its own gravity to achieve automatic sealing.

[0014] Furthermore, each of the shielding components is detachably connected to the frame.

[0015] Furthermore, the material of the shielding component is opaque, or a portion of the shielding component is transparent.

[0016] A laminar flow bed includes a laminar flow bed cover as described in any of the above-mentioned claims, the laminar flow bed cover being disposed around the outer periphery of the bed, and the inner cavity of the laminar flow bed cover being used to accommodate the bed and the patient on the bed.

[0017] The laminar flow bed hood and laminar flow bed of this invention, through multi-structure collaborative design, achieve multiple optimizations in terms of practicality in medical scenarios, patient experience, and infection control safety. The specific beneficial effects are as follows: Highly efficient protection of the bed canopy's inner cavity, reducing the risk of infection: Utilizing the multi-stage air filtration and positive pressure maintenance function of the clean air supply device, clean air is continuously delivered while preventing the intrusion of unfiltered external air. Combined with the sealing ring for the closed gap of the through-slot, the automatic resetting and sealing of the sealing plate driven by the gravity of the limiting component, and the magnetic adsorption and gravity resetting sealing of the flexible shielding component, a multi-layered protection of "filtration-positive pressure-gap sealing-automatic channel closure" is formed. This effectively isolates external dust and microorganisms, creating a stable and clean protective space for patients with weakened immune function, such as those in hematology and oncology departments, significantly reducing the risk of infection.

[0018] Improving clinical ease of operation and reducing workload for medical staff: The through-slot of the rigid shielding component provides a dedicated passage for the transfer of items, eliminating the need to open the entire shielding assembly; after the diaphragm is opened, it can be kept horizontal by the hinged support, which also serves as a temporary load-bearing function, avoiding the need for additional load-bearing tools; the adsorption cooperation between the limiting component and the magnetic component allows the diaphragm to be automatically closed by manual separation, without the need for manual pushing; the flexible shielding component supports partial opening to meet the needs of operations such as infusion puncture and local care; the detachable connection of all shielding components and the frame facilitates patient access and component cleaning and replacement, greatly simplifying medical staff operation procedures and reducing workload.

[0019] Balancing patient privacy and comfort to enhance the user experience: The opaque material design of the shielding components effectively protects the patient's body position, facial features, and other privacy information. At the same time, partially transparent areas (such as the middle of the rigid shielding component, the sealing plate, and the upper part of the flexible shielding component) allow medical staff to observe the patient's condition without opening the components, balancing privacy protection and nursing needs. The laminar flow bed cover directly encloses the conventional hospital bed, allowing patients to enjoy a clean space without being moved, avoiding discomfort or fluctuations in their condition caused by movement. The clean air supply device can be adapted to airflow adjustment needs, and the flexible opening and automatic resetting of the flexible shielding components also reduces restrictions on patient movement, improving overall patient comfort.

[0020] With a stable structure and flexible adaptability, it is suitable for various scenarios: the frame provides solid support and the structure can be adjusted according to the size of the hospital bed (such as adding or removing crossbars, folding design) to adapt to different medical scenarios; the magnetic fixation of the limiting parts can be replaced with buckles, Velcro, etc., the pull rope can be replaced with other flexible ropes, and the shape of the through slot and the number of flexible shielding parts can be adjusted as needed; the laminar flow bed cover can be used with conventional hospital beds or designed as an integrated structure with the hospital bed, adapting to the needs of multiple departments such as hematology, oncology, and burn departments, and has wide applicability and flexible adjustment space.

[0022] The meanings of the labels in the attached diagram are as follows: Frame 100, shielding assembly 200, rigid shielding component 210, through groove 211, sealing plate 212, sealing ring 213, hinge component 214, pull rope 215, limiting component 216, magnetic component 2161, wire hole 217, magnetic suction component 218, flexible shielding component 220, clean air supply device 300. Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Reference Figures 1-7 As shown, in this embodiment, the core structure of the laminar flow bed cover includes a frame 100, a shielding component 200, and a clean air supply device 300. The frame 100 serves as the overall support foundation, providing a stable mounting platform for the shielding component 200 and the clean air supply device 300, ensuring that the entire laminar flow bed cover is not easily deformed during use, thereby maintaining the spatial stability of the bed cover's interior. The overall shape of the frame 100 adapts to the contours of a conventional hospital bed, forming a complete support structure around the bed. Its material is selected to meet the requirements of medical settings, possessing sufficient load-bearing capacity to support the weight of each component, and withstanding daily cleaning and disinfection operations, avoiding the risk of contamination due to material issues. In other embodiments, the specific structure of the frame 100 can be adjusted according to the actual size of the hospital bed, for example, by increasing or decreasing the number of support crossbars, or by adopting a foldable design to improve storage convenience when not in use, as long as it can achieve the basic support function for each component.

[0025] The shielding component 200 is a key part of constructing the inner cavity of the bed cover. In this embodiment, multiple shielding components 200 are provided, respectively installed on each side of the frame 100. The shielding components 200 cooperate with each other to form the inner cavity of the bed cover for accommodating the patient. This enclosure structure isolates the external environment from direct contact with the inner cavity, creating a relatively independent protective space for the patient. At least one shielding component 200 adopts a structure combining a rigid shielding member 210 and a flexible shielding member 220. Both the rigid shielding member 210 and the flexible shielding member 220 are directly connected to the frame 100. The advantage of this combination design is that the rigid shielding member 210 ensures the stability of the local structure and prevents the shielding component from shifting due to external force, while the flexible shielding member 220 improves the flexibility of operation and meets the needs of temporary opening and closing.

[0026] In this embodiment, the rigid barrier 210 has a through groove 211. The main function of the through groove 211 is to provide a dedicated passage for transferring items between the inner cavity of the bed cover and the outside. When transferring items such as medicines, meals, or medical consumables through this passage, it is not necessary to open the entire barrier assembly 200, thereby avoiding damage to the cleanliness of the inner cavity due to large-area opening. To control the opening and closing state of the through groove 211, a sealing plate 212 is hinged to the rigid barrier 210. The sealing plate 212 can be rotated around the hinge point, thereby opening or closing the through groove 211. At the same time, a sealing ring 213 is provided on the side of the sealing plate 212 facing the through groove 211. When the sealing plate 212 closes the through groove 211, the sealing ring 213 can fill the gap between the sealing plate 212 and the edge of the through groove 211, effectively ensuring the airtightness of the inner cavity of the bed cover and preventing external dust, microorganisms, and other contaminants from entering the inner cavity through the gaps. In other embodiments, the shape of the through groove 211 can be adjusted to be circular or elliptical according to the type of common items to be transferred, and the material of the sealing ring 213 can also be replaced with other elastic materials with medical-grade sealing performance, as long as the dual functions of item transfer and airtight protection can be achieved at the same time.

[0027] In this embodiment, the sealing plate 212 is positioned on the side of the rigid barrier 210 facing the inner cavity of the bed cover. Its lower side is connected to the rigid barrier 210 via a hinge 214. This installation design avoids the sealing plate 212 occupying external operating space when opened outwards, reducing interference with the daily operations of medical staff. The upper end face of the hinge 214 forms a support portion. When the sealing plate 212 is flipped open to the rear (i.e., the side facing the inner cavity), this support portion can fit against the lower surface of the sealing plate 212, thereby keeping the sealing plate 212 in a horizontal state. The horizontal sealing plate 212 can serve as a temporary support surface for placing medical supplies or small personal items transferred to the inner cavity, eliminating the need for additional dedicated support tools and effectively improving convenience during use. In other embodiments, the type of hinge 214 can be replaced with a damping hinge, allowing the sealing plate 212 to remain at any angle during flipping, further improving operational flexibility, as long as the function of supporting the sealing plate 212 to maintain a horizontal state is achieved.

[0028] To further enhance the stability of the sealing plate 212 when it is in a horizontal state, and to achieve the automatic reset and sealing function of the sealing plate 212, in this embodiment, the laminar flow bed cover is also equipped with a pull rope 215 and a limiting member 216. The rigid shielding member 210 has a wire hole 217, and the wire hole 217 is located above the through groove 211. One end of the pull rope 215 is connected to the end of the sealing plate 212 away from the hinge member 214, and the other end passes through the wire hole 217 from the inner cavity side of the bed cover and is connected to the limiting member 216. When the limiting member 216 is not fixed to the rigid blocking member 210, its own weight will pull the end of the sealing plate 212 away from the hinge member 214 through the pull rope 215, thereby driving the sealing plate 212 to rotate upward around the hinge member 214, and finally realize the automatic closure of the through slot 211. When the sealing plate 212 is kept in a horizontal state, the limiting member 216 can abut against the outside of the rigid blocking member 210, and apply an upward pulling force to the end of the sealing plate 212 away from the hinge member through the pull rope 215, forming a "two-point support" structure with the support part of the hinge member 214. This structure can effectively prevent the sealing plate 212 from sagging due to the weight it bears, ensure safety during the temporary bearing process, and prevent items placed on the sealing plate 212 from falling. In other embodiments, the pull rope 215 can be replaced with other flexible ropes with a certain strength, such as nylon rope or polyester rope. The number of wire holes 217 can also be adjusted according to the number of pull ropes 215, as long as they can work with the limiting member 216 to achieve stable support and automatic reset and closure of the sealing plate 212.

[0029] In this embodiment, magnetic components 2161 are provided at both ends of the limiting member 216, and magnetic suction components 218 are provided on the outer side of the rigid blocking member 210 corresponding to the positions of the magnetic components 2161. To keep the sealing plate 212 in the open state (i.e., the horizontal state), the limiting member 216 needs to be attracted and fixed to the magnetic suction components 218 of the rigid blocking member 210 through the magnetic components 2161. By fixing the position of the limiting member 216, its own weight is counteracted, preventing the limiting member 216 from pulling the pull rope 215 downward due to gravity and causing the sealing plate 212 to flip upward and reset, thereby stably maintaining the open state of the sealing plate 212. At the same time, the magnetic attraction connection method has good detachability. Medical staff only need to manually apply a certain external force to separate the magnetic components 2161 and the magnetic suction components 218, making it convenient to adjust the state of the sealing plate 212. Furthermore, the outer diameter of the magnetic component 2161 is larger than the outer diameter of the rod of the limiting component 216. When the magnetic component 2161 abuts against the rigid barrier 210, a certain gap is formed between the rod of the limiting component 216 and the rigid barrier 210. This gap facilitates medical personnel in grasping the rod to operate the limiting component 216, avoiding difficulty in gripping due to the rod being too close to the barrier. The magnetic component 2161 adopts a regular hexagonal structure, and its plane can fit and adhere to the magnetic component 218. Compared with a circular component, this reduces rotational displacement after adsorption, further improving the stability of the connection. In other embodiments, the cooperation method between the magnetic component 2161 and the magnetic component 218 can be replaced by a snap-fit ​​or Velcro fit, as long as the fixing and easy disassembly of the limiting component 216 can be achieved, thereby enabling the opening and holding and automatic reset and closure of the sealing plate 212.

[0030] In this embodiment, multiple flexible shielding components 220 are provided, all of which are vertically arranged. This design enables a "partial opening" function. When medical staff need to perform local nursing procedures, or when the patient needs to extend their arm for intravenous puncture or movement, only one or more flexible shielding components 220 need to be opened, without opening the entire shielding assembly 200, effectively preventing damage to the cleanliness of the bed cover cavity due to large-area opening. Adjacent flexible shielding components 220 and the outermost flexible shielding component 220 can be magnetically attracted to achieve a closed seal, ensuring airtightness when not open. Simultaneously, the flexible shielding components 220 can reset under their own gravity; that is, after opening and releasing, the flexible shielding component 220 will naturally droop due to gravity and re-adhere to adjacent components, achieving automatic sealing without manual adjustment by medical staff or patients, simplifying the operation process. In other embodiments, the number of flexible shielding members 220 can be adjusted according to the width of the frame 100, and the position of magnetic adsorption can also be adjusted to a local area of ​​the edge, as long as the function of partial opening and automatic sealing can be achieved.

[0031] In this embodiment, each shielding component 200 is detachably connected to the frame 100. This connection method facilitates the removal and removal of the shielding component 200 by medical staff according to actual needs. For example, when a patient needs to enter or exit the bed cover, the shielding component 200 on one side of the frame 100 can be detached to form a spacious passage, preventing the patient from crossing the frame or squeezing the shielding component. Similarly, when the shielding component 200 is stained with medication or blood and needs cleaning, or is damaged and needs replacement, it can be disassembled and handled separately, significantly improving the convenience of equipment maintenance. In other embodiments, the specific structure of the detachable connection can be adjusted according to the needs of the usage scenario, as long as it allows for convenient assembly and disassembly between the shielding component 200 and the frame 100.

[0032] In this embodiment, the material of the shielding component 200 can be an opaque material or a transparent material in some areas. An opaque material effectively protects the patient's privacy, preventing outsiders from directly observing the patient's position, facial condition, and other private information. A partially transparent material is placed in easily observable areas, such as the middle of the rigid shielding component 210, the upper part of the entire sealing plate 212, or the flexible shielding component 220. Made of transparent medical material, these transparent areas allow medical staff to directly observe the patient's condition inside the bed cover without opening the shielding component 200, such as whether the infusion line is unobstructed or whether the patient is making any abnormal movements. This achieves a balance between protecting patient privacy and meeting the observation needs of medical staff. In other embodiments, the position and area of ​​the transparent area can be adjusted according to actual observation needs. For example, a transparent area can be placed near the head of the bed to facilitate observation of the patient's facial condition, as long as a balance between privacy protection and observation needs is achieved.

[0033] In this embodiment, the clean air supply device 300 is installed above the frame 100, and its core function is to continuously supply clean air to the inner cavity of the bed cover. This device integrates an air filtration structure that performs multi-stage filtration of external air, removing dust, microorganisms, and other contaminants before delivering the filtered clean air into the inner cavity. Simultaneously, the clean air supply device 300 maintains a positive pressure environment within the inner cavity. This positive pressure prevents unfiltered external air from entering the inner cavity through gaps in the shielding components, ensuring that the air inside the bed cover remains clean and reducing the risk of infection caused by inhaling contaminants. In other embodiments, the clean air supply device 300 can be installed on the side of the frame 100, as long as it effectively delivers clean air to the inner cavity of the bed cover. Furthermore, the device can be equipped with an airflow adjustment function, allowing medical personnel to adjust the clean air delivery rate according to the patient's needs or the actual conditions of the inner cavity, further improving patient comfort.

[0034] In this embodiment, the laminar flow bed includes a hospital bed and any of the aforementioned laminar flow bed covers. The laminar flow bed covers are arranged around the perimeter of the hospital bed, and the internal space of the bed covers is adapted to the size of the hospital bed, fully accommodating the hospital bed and the patient on it. This structural design does not require modification of existing hospital beds; a local clean space can be created for the patient on the bed directly through the laminar flow bed covers, significantly reducing the cost of equipment use. Simultaneously, patients do not need to be transferred from the hospital bed to specialized equipment, reducing the risk of physical discomfort or fluctuations in condition caused by movement. This is particularly suitable for patients with limited mobility or weakened immune function, such as hematology and oncology patients. In other embodiments, the frame 100 of the laminar flow bed covers can be designed as an integrated structure with the hospital bed, i.e., the frame 100 is directly fixed to the hospital bed, further improving the overall stability of the laminar flow bed, as long as the function of accommodating the hospital bed and patient within the bed covers is achieved.

[0035] In actual use, medical staff first disassemble the shielding component 200 on one side of the frame 100 to create a passage for the patient to enter and exit. After the patient lies down on the bed, the medical staff reinstall the disassembled shielding component 200 back onto the frame 100, ensuring that all shielding components 200 are tightly closed to form a sealed bed cover cavity. Subsequently, the medical staff activate the clean air supply device 300 installed above the frame 100. The device begins to deliver clean air into the bed cover cavity and gradually establishes a positive pressure environment within the cavity. Once the device is running stably, the clean air delivery parameters can be adjusted according to actual needs. When it is necessary to pass items into the inner cavity, medical staff first manually lift the limiting member 216 until the magnetic components 2161 at both ends are attracted to the magnetic components 218 on the rigid shield 210, allowing the limiting member 216 to loosen the pull rope 215. Then, the sealing plate 212 is flipped towards the inner cavity of the bed cover until the sealing plate 212 is attached to the support part of the hinge 214 and remains horizontal. The limiting member 216 is fixed by the magnetic components 2161 and the magnetic components 218, which will counteract the weight of the limiting member 216 and maintain the sealing plate 212. With the 12 panel open, items can be placed on the horizontal sealing plate 212. After use, if it is necessary to close the passageway 211, medical staff only need to manually separate the magnetic component 2161 from the magnetic suction component 218, thus releasing the fixed state of the limiting component 216. At this time, the limiting component 216 will pull the pull rope 215 downward under its own weight, thereby driving the sealing plate 212 to rotate upward around the hinge 214, ultimately achieving automatic closure of the passageway 211 without the need for additional manual pushing of the sealing plate 212. Medical staff can observe the patient's condition through the partially transparent area of ​​the shielding component 200 without opening the shielding component. When the patient needs to perform slight activities, one or more flexible shielding components 220 can be manually opened. After the activity is over, the flexible shielding components 220 can be released, and they will reset under their own weight and close through magnetic adsorption, restoring the airtightness of the bed cover cavity. When the shielding component 200 needs to be cleaned or replaced, medical staff only need to remove the corresponding shielding component 200, clean and disinfect it or replace it with a new shielding component, and then reinstall it back into the frame 100.

[0036] In summary, the laminar flow bed cover and laminar flow bed in this embodiment, through reasonable structural design, significantly improve the flexibility and patient comfort during use while ensuring the cleanliness and airtightness of the bed cover cavity. By combining the through-slots, sealing plates, and sealing rings on the rigid shielding components, along with the automatic resetting and sealing function of the sealing plates achieved by the gravity of the limiting components, a highly efficient balance between item transfer and airtight protection is achieved, effectively avoiding the risk of contamination caused by frequent opening of the overall shielding assembly. The horizontal support design of the sealing plates, combined with the magnetic fixing structure of the limiting components, gives the sealing plates a dual function of "opening and closing channel + temporary support," and allows for simple magnetic operation to control the opening and closing of the sealing plates, further improving the convenience of clinical operation. The partial opening and gravity resetting design of the flexible shielding components meets the needs of temporary patient movement and local medical staff operations, and achieves automatic sealing without manual adjustment, simplifying the operation process. The detachable connection between the shielding components and the frame, and the differentiated design of transparency, respectively improve the convenience of equipment maintenance and the protection of patient privacy. The integrated adaptation design of the laminar flow bed can create a clean space without moving the patient, reducing the risk of patient movement. The overall solution fully adapts to the core needs of medical scenarios, such as infection control and ease of operation, and comprehensively considers the patient's user experience, possessing high clinical practical value.
