Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a warning sign at the end of an arteriovenous fistula bed with zoning information locking and quick installation functions. Background Technology
[0002] In modern clinical nursing systems, arteriovenous fistulas (AVFs) serve as the "lifeline" for maintenance hemodialysis patients, making their safe management crucial. Due to the unique nature of AVFs, any improper operation, such as external compression or incorrect puncture, can lead to vascular stenosis, thrombosis, or even functional loss, seriously threatening the patient's life and health. Therefore, placing prominent warning signs at the foot of the bed, clearly indicating key information such as nursing precautions and medication contraindications, is a necessary measure to ensure medical safety. Currently, commonly used bedside warning signs in clinical practice mainly take the form of hanging panels, card inserts, or plastic markers. Hanging panels are suspended at the foot of the bed via hooks or straps, using printed or pasted text and symbols to convey information. Card inserts allow medical staff to insert cards with different content based on the patient's condition, enabling information updates. Plastic markers are mostly injection molded, using color or raised patterns for differentiation. While these warning signs meet basic information needs to a certain extent, they still have many shortcomings in practical application. For example, changing the information on the warning signs is cumbersome and difficult to adapt to rapidly changing clinical nursing needs; the signs are easily rotated by external force, causing misalignment or obstruction of warning information, failing to accurately convey the patient's personalized nursing requirements; and the fixing methods are not stable enough, easily loosening, shifting, or even falling off under frequent patient movement, routine nursing operations, or ward environment disturbances, leading to the invalidation of warning information. These problems seriously affect the effectiveness of the warning signs and the accuracy of information transmission, urgently requiring a more reliable and convenient new type of bedside warning sign to improve the safety and quality of care for patients with arteriovenous fistulas. Summary of the Invention
[0003] To address the problems of unstable fixing, weak positioning function, and inconvenient information replacement in existing bedside warning signs, this utility model provides a bedside warning sign for arteriovenous fistulas, aiming to improve the stability, reliability, and ease of operation of the warning sign, accurately convey patient care information, and ensure the safety of arteriovenous fistula patients.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a warning sign at the foot of an arteriovenous fistula bed, comprising a disc-shaped shell, the disc-shaped shell being composed of a back plate, a front plate, and peripheral side plates, with an inner cavity formed between the back plate and the front plate, and a through observation window on the front plate; a central mounting base is fixedly installed at the center of the back plate, the central mounting base having an axially extending stepped mounting hole, and an axially extending limiting block on the inner wall of the mounting hole; a limiting plate is embedded in the mounting hole, the limiting plate having a limiting groove that slides with the limiting block, allowing the limiting plate to move axially within the mounting hole; a reset component is provided in the mounting hole to push the limiting plate to elastically reset; and an outwardly extending pressing mechanism is fixedly connected to the limiting plate. The button has multiple axially extending positioning blocks circumferentially arranged on its outer wall. A partitioned warning disc, coaxially arranged with the disc-shaped housing, is located in the cavity between the back plate and the front panel. The disc surface on one side of the front panel is evenly divided into multiple warning zones circumferentially. A sleeve is fixedly connected to the center of the partitioned warning disc. The sleeve is fitted around the button, and its inner wall has a positioning groove that mates with the positioning blocks. One end of the sleeve is rotatably connected to a limiting groove in the central mounting seat. When the button is pressed, the limiting plate compresses the reset assembly, causing the positioning blocks to disengage from the positioning groove to release the rotation restriction on the partitioned warning disc. After the button is released, the reset assembly pushes the limiting plate back to its original position, and the positioning blocks insert into the positioning groove to lock the partitioned warning disc.
[0005] Furthermore, the reset assembly includes a first spring, the two ends of which abut against the bottom wall of the stepped mounting hole and the limiting plate, respectively.
[0006] Furthermore, the number of positioning blocks is 3-6, and they are equidistantly distributed along the circumference of the button; the number and position of the positioning slots correspond to and match the positioning blocks.
[0007] Furthermore, the back of the disc-shaped housing back plate is provided with a strap assembly for securing the disc-shaped housing.
[0008] Furthermore, the strap assembly includes at least two straps, one end of each strap is fixedly connected to the disc-shaped housing, and the free end of one strap is connected to a connecting buckle, which is used to lock the free end of the other strap.
[0009] Furthermore, a locking plate is hinged to the connecting buckle via a pivot. The inner side of the locking plate is provided with anti-retraction teeth that engage and fix the strap inserted into the limiting groove three inside the connecting buckle. The connecting buckle is provided with a locking component for locking the locking plate.
[0010] Furthermore, the locking assembly includes a locking block, one end of which is connected to a limiting plate three that is slidably embedded inside the locking plate and a third spring that cooperates with the limiting plate three. A locking hole that cooperates with the locking block is provided on the side plate of the connecting buckle.
[0011] Furthermore, an unlocking component is provided on the side plate of the buckle at the position corresponding to the lock hole. The unlocking component includes a second limiting plate, a pressure rod, and a second spring. The second limiting plate is slidably disposed inside the connecting buckle. The pressure rod extending outward is fixedly connected to the second limiting plate. The second spring is sleeved on the outside of the pressure rod, with its two ends abutting against the second limiting plate and the inner wall of the connecting buckle, respectively. When the pressure rod is pressed, the second limiting plate pushes the locking block to disengage from the lock hole.
[0012] This utility model has the following beneficial effects: (1) The precise positioning and stable locking of the partition warning disc are achieved through the cooperation of the pressing button, positioning block, positioning slot and reset component. When it is necessary to adjust the warning information, press the pressing button to make the positioning block disengage from the positioning slot, and the partition warning disc can be easily rotated to align the required warning area with the observation window; after releasing the pressing button, the reset component pushes the limit plate to reset, the positioning block inserts into the positioning slot, and firmly locks the partition warning disc, effectively preventing random rotation caused by external force, and ensuring accurate and stable display of warning information; (2) Through the design of the strap assembly, two sets of straps, together with the connecting buckle, locking plate, locking component and unlocking component, achieve a stable connection between the warning sign and the hospital bed. The anti-retraction tooth design of the connecting buckle and locking plate, combined with the reliable locking function of the locking component, makes the straps less likely to loosen or fall off after being fixed. Even in environments with frequent patient movement or frequent nursing operations, the warning sign can be stably hung, effectively avoiding the problem of warning information failure; (3) The operation of this utility model is convenient and efficient. Whether it is adjusting the warning information or installing and disassembling the warning sign, medical staff can complete it quickly. The angle of the warning plate can be adjusted by pressing the button, without the need for complicated tools. The connection and unlocking of the strap component is simple and can quickly adapt to the installation needs of different beds, greatly improving the efficiency of nursing work and meeting the rapidly changing nursing needs in clinical practice.
