[0026] The current technology works by installing telescopic plates inside the platform and adjusting the area of the extended plates using bolts, thereby adjusting the area of the platform top to accommodate more medicines. However, existing devices require adjusting multiple bolts on both sides, making the process cumbersome, inefficient, and impractical in actual use.
[0027] As shown in the attached figures, this utility model embodiment provides a nursing dressing change device.
[0028] The device includes: a platform 12 fixedly mounted on the top of the main body 11 of the dressing cart; an adjustment assembly 2 disposed inside the platform 12, the adjustment assembly 2 including: a rotating rod 21 whose bottom end is inserted into the interior of the platform 12 and rotatably connected to the platform 12; a turntable 22 fixedly sleeved on the outer side wall of the bottom end of the rotating rod 21; a guide groove 23 opened on the top of the turntable 22; an extension plate 24 whose end is inserted into the interior of the platform 12; and a sliding rod 25 slidably disposed inside the guide groove 23 and whose top end is fixedly connected to the bottom of the extension plate 24.
[0029] Specifically, the main body of the dressing cart 11 typically includes a four-drawer system. The top drawer is used to store dressing instruments, the second and third drawers are divided into dressing and instrument storage areas, and the bottom drawer houses a medicine cabinet or waste disposal area. Some high-end models are equipped with an ultraviolet disinfection system, which activates the disinfection program through a sealed space, achieving a disinfection intensity of up to 90μW / cm².
[0030] Mobile Design
[0031] Featuring dual-brake, silent casters for flexible movement, some models are equipped with an electric shifting function, enabling battery-powered transport. Casters with a diameter of 100-125mm ensure stable parking even in confined spaces like hospital wards.
[0032] Categorized storage
[0033] Medicines, medical devices, and waste are categorized and managed using dividers and signage. Some models are equipped with detachable mesh baskets for temporary storage of contaminated medical devices. Pediatric-specific models are equipped with anti-accidental-touch locks to ensure operational safety.
[0034] In use, first store the medicine in the drawer on the main body 11 of the dressing cart, and move it to the side of the bed using the bottom rollers. Then, simply grasp the rotating rod 21 and control it to rotate clockwise. As it rotates, the turntable 22 at the bottom will also rotate. During the rotation of the turntable 22, the sliding rod 25 can be dragged to slide inside the guide groove 23, pushing the extension plate 24 out from inside the platform 12 to adjust the area of the platform 12. After adjustment, more medicine can be placed, improving practicality. Simply place the medicine on the top of the platform 12 and the extension plate 24 for later use. After the dressing is changed, store the medicine, and then rotate the rotating rod 21 counterclockwise to retract the extension plate 24 into the inside of the platform 12 to complete the storage.
[0035] In some embodiments, the adjustment assembly 2 further includes a knob 26 fixedly disposed on the top of the rotating rod 21.
[0036] The knob 26 is easy to grip and controls the rotation of the rotating rod 21. At the same time, the groove on the surface of the knob 26 can increase the friction when rotating.
[0037] In some embodiments, the adjustment component 2 further includes a groove 27 formed on the top of the extension plate 24.
[0038] The groove 27 is designed to prevent medicines from slipping off the top of the extension plate 24 when medicines are placed in it.
[0039] In some embodiments, the adjustment component 2 further includes: protrusions 28 fixedly disposed on both sides of the platform 12, with their bottom ends inserted into the interior of the groove 27.
[0040] The design of the protrusion 28 allows it to scrape the inside of the groove 27 when the extension plate 24 retracts, preventing impurities from entering the inside of the platform 12.
[0041] In some embodiments, a fixing component 3 is provided on the rotating rod 21. The fixing component 3 further includes: a cylinder 31 fixedly disposed on the top of the platform 12; an insert rod 32 fixedly disposed on the bottom of the knob 26; and a rectangular rod 33 whose top end penetrates the inner sidewall of the rotating rod 21 and is fixedly connected to the knob 26.
[0042] During adjustment, simply pull the knob 26 upwards while the rectangular rod 33 extends out from inside the rotating rod 21, and the insert rod 32 disengages from the cylinder 31, releasing the fixation on the knob 26. Then, control the knob 26 to rotate. Due to the design of the rectangular rod 33, it can drive the rotating rod 21 to rotate as well. After adjustment, press the knob 26 downwards to insert the rectangular rod 33 into the interior of the rotating rod 21. At the same time, the bottom end of the insert rod 32 is inserted into the interior of the cylinder 31 to restrict the rotating rod 21 and stabilize the position of the extension plate 24.
[0043] In some embodiments, the fixing component 3 further includes a baffle 34 fixedly disposed at the bottom of the rectangular rod 33.
[0044] The design of the baffle 34 can prevent the bottom end of the rectangular rod 33 from detaching from the rotating rod 21.
[0045] In some embodiments, the fixing component 3 further includes: a spring 35 sleeved on the outside of the rectangular rod 33, and its two ends fixedly connected to the inner sidewall of the rotating rod 21 and the baffle 34, respectively.
[0046] The spring 35's own rebound force can push the baffle 34 to move downwards, causing the knob 26 to move downwards as well, making it difficult for the insertion rod 32 and the cylinder 31 to separate easily.
[0047] In some embodiments, the fixing component 3 further includes a cone 36 fixedly disposed at the bottom of the insertion rod 32.
[0048] The pointed end of the cone 36 is designed to make it easier to insert into the cylinder 31.
[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
