Description

Technical Field

[0001] This utility model relates to a labeling device for hospital infection control, and more particularly to a labeling device for isolating multidrug-resistant bacteria. Background Technology

[0002] In modern healthcare settings, nosocomial infections of multidrug-resistant organisms (MDRBs) have become an increasingly serious public health challenge. To effectively curb their spread within hospitals and ensure the safety of patients and healthcare workers, timely and appropriate isolation measures for patients infected with or colonized with MDRBs are crucial. Clear and standardized isolation signage at ward entrances is a key step in implementing isolation measures and reminding all personnel entering the ward to take appropriate protective measures (such as wearing gloves, masks, and gowns).

[0003] Currently, the isolation signage commonly used in clinical practice is rather simple and traditional. Medical institutions typically pre-print different types of paper or simple plastic signs, such as specific "contact isolation," "droplet isolation," or "airborne isolation" signs. When specific isolation of a patient is required, medical staff must find the corresponding sign from inventory and affix it to the ward door using tape or other methods. This method presents several inconveniences. First, when isolation measures are adjusted, medical staff must manually remove the old signs and replace them with new ones, a cumbersome process. Second, departments need to store and manage multiple independent signs, which not only occupies storage space but also increases the complexity of logistical management. Furthermore, paper or simple signs are easily damaged, faded, and contaminated; their lifespan is short after wiping or soaking with disinfectant; and the common clinical method of affixing signs with tape is neither secure nor aesthetically pleasing, failing to meet the standardized and regulated management requirements of modern hospitals. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide a multidrug-resistant bacteria isolation and labeling device.

[0005] To achieve the above objectives, the multidrug-resistant bacteria isolation and labeling device according to an embodiment of the present invention includes:

[0006] Bottom cover;

[0007] A signboard, which is disposed on the bottom cover and is rotatable relative to the bottom cover about its own axis, has multiple marking areas on its surface, which are arranged sequentially along the circumference of the signboard, and each marking area includes a theme sub-area and a protective sub-area, which are arranged symmetrically in the radial direction;

[0008] A cover is provided over the signboard and has a display window, which includes a main sub-window and a protective sub-window.

[0009] The signboard is configured to selectively switch one of the plurality of sign areas opposite the display window by rotation, so that the content of the theme sub-area is displayed in the theme sub-window and the content of the protection sub-area is displayed in the protection sub-window.

[0010] The multidrug-resistant bacteria isolation labeling device provided in this embodiment integrates multiple isolation types (such as contact, droplet, airborne, and protective isolation) and their corresponding specific protection requirements onto a single device by setting a rotatable label plate. Users can quickly and accurately switch and display the required isolation information simply by rotating the label plate. This device eliminates the cumbersome process of finding, removing, and replacing individual labels, significantly improving the work efficiency of medical staff.

[0014] According to one embodiment of the present invention, the bottom cover includes a bottom plate and a central post, wherein the central post is located at the center of the bottom plate and protrudes toward one side of the marking plate;

[0015] The surface of the signboard adjacent to the base plate is provided with a pivot hole, which extends into the knob portion and pivotally engages with the central column, so that the signboard can rotate relative to the base cover.

[0016] According to one embodiment of the present invention, the base plate is provided with a plurality of teeth, which are arranged circumferentially around the central column.

[0017] The label plate is provided with a toothed groove. When the label plate is rotated, the toothed groove can selectively engage with one of the plurality of teeth so that one of the plurality of label areas is opposite to the display window.

[0018] According to one embodiment of the present invention, a spring is sleeved on the knob, one end of the spring abuts against the label plate, and the other end of the spring abuts against the face cover.

[0019] According to one embodiment of the present invention, the bottom cover further includes a periphery, which is disposed on the bottom plate, and the outer side of the periphery is provided with an L-shaped groove;

[0020] The inner peripheral wall of the cover has a locking part. When the cover is closed on the bottom cover, the periphery is located inside the inner peripheral wall of the cover. The locking part is inserted into the axial section of the L-shaped slot. After the cover rotates a predetermined angle, the locking part enters the circumferential section of the L-shaped slot and locks in place.

[0021] According to one embodiment of the present invention, the bottom cover is provided with a suction cup or hook for installing the multidrug-resistant bacteria isolation labeling device to a predetermined position in the usage environment.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0057] The multidrug-resistant bacteria isolation and marking device of this utility model is described in detail below with reference to the accompanying drawings.

[0058] Reference Figures 1 to 4 As shown, the multidrug-resistant bacteria isolation labeling device provided according to the embodiment of this utility model includes a bottom cover 10, a labeling plate 20, and a top cover 30.

[0059] Specifically, the bottom cover 10 can be injection molded from high-strength engineering plastics (such as ABS or PC) to ensure structural stability and durability, and to facilitate cleaning and disinfection. In this embodiment, the overall outline of the bottom cover 10 can be designed as a flat circle or square. A mounting structure can be provided on the back of the bottom cover 10 for fixing it to the ward door or wall.

[0060] The signboard 20 is disposed on the bottom cover 10 and is rotatable relative to the bottom cover 10 about its own axis. The surface of the signboard 20 has multiple sign areas, which are arranged sequentially along the circumference of the signboard 20. Each sign area includes a theme sub-area P20a and a protection sub-area P20b, which are arranged symmetrically in the radial direction.

[0061] The labeling plate 20 is a component for carrying and switching information. In this embodiment, the labeling plate 20 is a disc-shaped structure and pivotally engages with the bottom cover 10, allowing it to rotate freely relative to the bottom cover 10 around its central axis. The surface of the labeling plate 20 is evenly divided into multiple fan-shaped labeling areas along its circumference. Each labeling area corresponds to a specific type of isolation and protective measure. For example, four labeling areas can be set, including "contact isolation," "droplet isolation," "airborne isolation," and "protective isolation." For the standardization and intuitiveness of information, each labeling area is further divided radially into a theme sub-area P20a and a protective sub-area P20b. The theme sub-area P20a is used to prominently indicate the name of the isolation type and the isolated object, such as printing "contact isolation" in large font and indicating the isolated object as "patients with multidrug-resistant bacteria, enterovirus (rotavirus), skin wound infections, etc." in relatively small font. The protection sub-area P20b is used to specifically and visually display the protective measures that need to be taken under this type of isolation. For example, it uses printed graphic icons (such as hand hygiene, instrument use, wearing gloves, wearing isolation gowns, etc.) to remind medical staff of the protective measures that need to be taken.

[0062] A cover 30 is disposed over the signboard 20, and the cover 30 has a display window, which includes a main sub-window H30a and a protective sub-window H30b. Exemplarily, the cover 30 is detachably connected to the bottom cover 10 to form a housing that encloses the signboard 20.

[0063] The label panel 20 is configured to selectively switch one of the plurality of label areas opposite the display window by rotation, so that the content of the theme sub-area P20a is displayed in the theme sub-window H30a and the content of the protection sub-area P20b is displayed in the protection sub-window H30b.

[0064] In other words, a display window with a fixed position is provided on the cover 30. The shape, size, and position of this display window correspond to a single identification area on the signboard 20. Accordingly, the display window also includes a main sub-window H30a and a protective sub-window H30b that match the sub-areas of the identification area. When the signboard 20 is rotated to a specific position, one identification area is perfectly aligned with the display window, so that the content of the main sub-area P20a of that identification area is revealed through the main sub-window H30a, while the content of its protective sub-area P20b is revealed through the protective sub-window H30b. The rest of the cover 30 is opaque to block other unselected identification areas, ensuring the uniqueness and clarity of the displayed information and avoiding information interference.

[0065] In practical use, medical staff do not need any tools. For example, when it is necessary to implement "droplet isolation" for patients in a ward, the nurse only needs to use their finger to rotate the exposed sign plate 20 of the signage device until the main text "Droplet Isolation" and the corresponding protective measures such as masks appear in the display window. The entire switching process is intuitive and quick. When the isolation measures are changed or lifted, the signage can also be updated simply by rotating it.

[0066] The multidrug-resistant bacteria isolation labeling device provided in this embodiment integrates multiple isolation types (such as contact, droplet, airborne, and protective isolation) and their corresponding specific protection requirements onto a single device by setting a rotatable label plate 20. Users can quickly and accurately switch and display the required isolation information simply by rotating the label plate 20. This device eliminates the cumbersome process of finding, removing, and replacing individual labels, significantly improving the work efficiency of medical staff. Furthermore, this integrated structure combines multiple labeling functions, simplifying the hospital's storage and management of labels. Its enclosed structure is more robust and durable than paper labels, less prone to contamination and loss, and helps improve the standardization of hospital management and the cleanliness and aesthetics of the ward environment, making it highly practical.

[0067] In one embodiment of this utility model, the label plate 20 is snap-fitted to the bottom cover 10. This snap-fit ​​connection simplifies the assembly process and enables tool-free, rapid installation. Furthermore, the elimination of the need for additional screws, washers, or retaining rings to secure the label plate 20 improves structural reliability, ensuring that the label plate 20 will not loosen or detach during long-term use, thereby enhancing the overall structural stability, durability, and reliability of the device.

[0068] In one embodiment of the present invention, the face cover 30 has a through hole H31 at its center, and the label plate 20 has a knob 201 at its center. The knob 201 protrudes from one side of the face cover 30 and extends out from the through hole H31, so as to allow the user to operate and rotate the label plate 20.

[0069] When the user rotates the knob 201 clockwise or counterclockwise, the torque is directly transmitted to the label plate 20, thereby driving the label plate 20 to rotate relative to the fixed bottom cover 10 and front cover 30 until the content of the target label area is accurately aligned and displayed in the display window. In this way, the user does not need to search for the toggle point at the edge of the device; they can simply operate the knob 201 on the front. The operation path is shorter, and the interaction method is more intuitive and convenient, greatly improving the user-friendliness and efficiency of operation.

[0070] In one embodiment of the present invention, the bottom cover 10 includes a bottom plate and a central column 101, wherein the central column 101 is located at the center of the bottom plate and protrudes toward the side of the marking plate 20.

[0071] The surface of the sign plate 20 adjacent to the base plate is provided with a pivot hole H201. The pivot hole H201 extends into the knob portion 201 and pivotally engages with the central column 101 so that the sign plate 20 can rotate relative to the bottom cover 10.

[0072] After assembly, the central column 101 on the bottom cover 10 serves as a fixed central axis and is fitted into the pivot hole H201 of the marking plate 20, so that when the marking plate 20 is subjected to torque from the knob part 201, it can rotate stably and without wobbling around the central column 101.

[0073] The pivoting engagement structure, consisting of the central column 101 of the bottom cover 10 and the pivot hole H201 of the sign plate 20, enhances the mechanical stability and guiding properties of the sign plate 20. It effectively suppresses the tilting or swaying problems that may occur during rotation, ensuring that the sign plate 20 always remains horizontal and rotates concentrically. This ensures that the sign area and the display window can be precisely aligned, achieving reliable sign area rotation switching.

[0074] In one embodiment of this utility model, a plurality of teeth 103 are provided on the base plate, and the plurality of teeth 103 are arranged circumferentially around the central post 101. Exemplarily, each tooth 103 is a protrusion with a specific profile, for example, its top can be a smooth arc surface or a trapezoid with a guiding bevel.

[0075] The sign plate 20 is provided with a groove H202, the shape and size of which are adapted to the teeth 103. When the sign plate 20 is rotated, the groove H202 can selectively engage with one of the teeth 103 so that one of the multiple sign areas is opposite to the display window.

[0076] Preferably, a spring 21 is fitted on the knob part 201, one end of the spring 21 abuts against the label plate 20, and the other end of the spring 21 abuts against the face cover 30.

[0077] In the assembled state, the axis of spring 21 coincides with the axis of knob 201. One end face of spring 21 abuts against the label plate 20, and the other end face of spring 21 abuts against the inner surface of the cover 30. After the entire device is assembled, spring 21 is in a pre-compressed state, which causes spring 21 to generate a continuous axial elastic force. This elastic force pushes label plate 20, continuously pressing label plate 20 against bottom cover 10, ensuring that the toothed groove H202 on label plate 20 and the toothed portion 103 on bottom plate are tightly engaged, thereby positioning label plate 20 in a predetermined position, such that a labeling area on label plate 20 is opposite to the display window on cover 30.

[0078] When the user rotates the knob 201, the torque overcomes the positioning force generated by the axial pressure provided by the spring 21, allowing the tooth groove H202 to climb upwards along the inclined surface of the tooth 103 and pass the apex. After passing the apex, under the pressure of the spring 21, the tooth groove H202 quickly slides into the engagement position of the next tooth 103, thereby achieving gear shifting. This elastic force provided by the spring 21 makes each engagement and disengagement of the tooth groove H202 and the tooth 103 crisp and clean, thus forming a gear shifting process with clear feel and definite feedback.

[0079] The positioning and engagement structure, consisting of multiple teeth 103 on the base plate and toothed grooves H202 on the sign plate 20, achieves two key benefits. Firstly, it enables precise positioning of the sign plate 20, ensuring that its stopping position is consistently aligned with the preset location. This allows the display window to clearly and completely showcase the content of the target sign area, reducing the risk of information being difficult to identify due to misalignment. Secondly, this structure provides a superior user experience. The elasticity provided by the spring 21 allows the operator to clearly perceive each switching operation, enhancing operational reliability. Furthermore, this positioning engagement provides sufficient positioning capability in non-operating states, effectively preventing accidental rotation of the sign plate 20 and ensuring the stability of the isolated sign information.

[0080] In one embodiment of this utility model, the bottom cover 10 further includes a periphery 102, which is disposed on the base plate. The outer surface of the periphery 102 is provided with an L-shaped groove H10. To ensure the stability of the cover 30 during the closing process and the uniform force after locking, preferably, there are at least two L-shaped grooves H10, which are evenly distributed circumferentially. Each L-shaped groove H10 consists of an axial segment H10a and a circumferential segment H10b. The axial segment H10a extends along the central axis of the bottom cover 10, with its upper end opening at the top edge of the periphery 102 and its lower end communicating with one end of the circumferential segment H10b. The circumferential segment H10b extends along the circumference of the periphery 102, with its other end being a closed end, forming a blocking structure.

[0081] The inner peripheral wall of the cover 30 has a locking part 301. When the cover 30 is closed on the bottom cover 10, the periphery 102 is located inside the inner peripheral wall of the cover 30. The locking part 301 is inserted into the axial section H10a of the L-shaped groove H10. After the cover 30 is rotated by a predetermined angle, the locking part 301 enters into the circumferential section H10b of the L-shaped groove H10 and is locked and fixed.

[0082] The number and position of the locking parts 301 correspond to the number and position of the L-shaped slots H10. Each locking part 301 is a protruding structure that protrudes radially from the inner peripheral wall, and its shape and size are adapted to the slot width of the L-shaped slot H10 to ensure that it can slide smoothly in the slot and achieve effective locking.

[0083] When assembling and locking the face cover 30 and the bottom cover 10, the operator first places the face cover 30 directly above the bottom cover 10 and adjusts its initial angular position so that each locking part 301 on the inner peripheral wall of the face cover 30 aligns with the opening of the axial segment H10a of the L-shaped groove H10 on the periphery 102 of the bottom cover 10. Then, a downward pressure is applied axially, and the face cover 30 moves smoothly toward the bottom cover 10. During this process, the locking parts 301 smoothly slide into the axial segment H10a of the L-shaped groove H10 and slide downwards along the axial segment H10a until they reach the bottom of the axial segment H10a, at which point the face cover 30 and the bottom cover 10 are completely fitted together. In this state, the operator needs to rotate the face cover 30 relative to the bottom cover 10 by a preset angle, such as 30 degrees clockwise or 45 degrees counterclockwise. During rotation, due to the constraint of the L-shaped groove H10 wall, the locking part 301 smoothly enters the circumferential section H10b from the bottom of the axial section H10a and slides along the trajectory of the circumferential section H10b. When the locking part 301 slides to the closed end of the circumferential section H10b, its movement is blocked by the closed end, thus preventing further rotation. At this time, the locking part 301 is confined within the circumferential section H10b of the L-shaped groove H10, and the cover 30 can be effectively locked in the axial direction, preventing it from being directly lifted or disengaged, thereby achieving a firm and reliable locking and fixing between the cover 30 and the bottom cover 10.

[0084] In this embodiment, an extremely convenient installation and disassembly method is achieved. Users only need to perform two simple actions—alignment, pressing down, and rotation—to complete the locking process, without the need for any external tools. The operation is intuitive and efficient. Furthermore, the locking structure has high reliability. Through the mechanical engagement of the L-shaped slot H10 and the locking part 301, a stable axial limit is formed.

[0085] In some embodiments of this utility model, the bottom cover 10 is provided with a suction cup 11 or a hook for installing the multidrug-resistant bacteria isolation marking device to a predetermined position in the usage environment.

[0086] By incorporating suction cups 11 or hooks on the bottom cover 10, the device's installation versatility and adaptability to various scenarios are enhanced. It can be flexibly applied to various common medical environments such as glass, metal, and wood, enabling immediate use. Furthermore, a non-destructive installation method is provided, avoiding damage to surfaces such as walls compared to drilling or using strong adhesives. Moreover, the deployment, relocation, and recycling processes are greatly simplified, allowing for rapid installation or repositioning without any tools. This enables quick response to changes in ward layout or patient isolation levels, significantly improving work efficiency and device reusability.

[0087] In some embodiments of this utility model, the four marking areas use different background colors: the background color of the contact isolation marking area is blue, the background color of the droplet isolation marking area is pink, the background color of the air isolation marking area is yellow, and the background color of the protective isolation marking area is green.

[0088] By using different background colors for different marked areas, the speed and accuracy of information identification are effectively improved. Color, as a visual feature, is more eye-catching and quickly identifiable, providing a better warning effect. Furthermore, this strong association between isolation types and specific colors creates an intuitive conditioned reflex, reducing the risk of healthcare workers selecting the wrong protective equipment due to misreading, forgetting, or confusion of different isolation measures.
