Description

Technical Field

[0001] This utility model relates to a nursing medication dispensing device, and in particular to a highly adjustable nursing medication dispensing device, belonging to the field of medical and nursing technology. Background Technology

[0002] In medical and nursing work, medication preparation is an important part of daily diagnosis and treatment. Medical staff need to complete a series of operations such as drug verification, dissolution, extraction and mixing on the medication preparation device. Some traditional medication preparation devices are designed at a fixed height. Since medical staff have large differences in height, the fixed height operating platform can easily cause users to bend over or stand on tiptoe for a long time. This not only increases fatigue, but may also affect the accuracy of medication preparation due to improper operating posture, and may even cause occupational injury. Chinese Patent Publication No. CN222304366U discloses a highly adjustable nursing medication preparation device, relating to the technical field of devices specifically for medical use. It includes vials, a solvent bag, and an infusion tube with puncture needles at both ends. The first puncture needle punctures the solvent bag. A peristaltic pump driving the internal medication flow is installed on the infusion tube. Several vials are located above the second puncture needle. The device further includes: a translation mechanism connected to the vials to drive the vials to move horizontally; and a height adjustment mechanism connected to the second puncture needle to drive the second puncture needle to move vertically toward / away from one of the vials. This invention enables the preparation of medication from multiple vials to meet the medication preparation requirements of medical personnel.

[0003] However, while existing technologies enable height adjustment of the puncture needle during medication preparation, their core design focuses on automating the preparation of medications in multiple vials through the coordination of translation and height adjustment mechanisms. This results in a complex structure that is primarily designed for specific vial medication preparation scenarios, making it difficult to meet the diverse manual medication preparation needs in daily nursing care. Furthermore, the overall size is large, and the mobility is insufficient, making it difficult to adapt to the needs of transferring medications in various scenarios such as wards and treatment rooms. Therefore, a height-adjustable nursing medication preparation device is proposed. Utility Model Content

[0023] like Figure 1-4 As shown, this utility model embodiment provides a height-adjustable nursing medication dispensing device, including a fixing frame 1 and a height adjustment mechanism 2; In one embodiment, a caster wheel 14 is installed at the bottom of the fixed frame 1, and a movable column 10 is slidably connected to the fixed frame 1; a dispensing platform 11 is fixedly connected to the top of the movable column 10; the height adjustment mechanism 2 includes a through groove 20 opened on the fixed frame 1 and a fixed seat 22 fixedly connected to the fixed frame 1, a rack 21 is slidably connected to the inner side wall of the through groove 20, one side of the rack 21 is fixedly connected to the dispensing platform 11, a threaded rod 24 is threadedly connected to the inside of the fixed seat 22, one end of the threaded rod 24 is rotatably connected to a toothed block 23 through a bearing, the toothed block 23 meshes with the rack 21 and is slidably connected inside the fixed seat 22; a disc 25 is fixedly connected to the other end of the threaded rod 24; Rotating the disc 25 drives the threaded rod 24 to rotate. The threaded engagement between the threaded rod 24 and the fixed seat 22 causes the threaded rod 24 to push the toothed block 23 to slide along the fixed seat 22. The toothed block 23 meshes with the rack 21, which in turn drives the rack 21 to rise and fall along the through groove 20. Finally, the fixed connection between the rack 21 and the dispensing platform 11 achieves height adjustment. The sliding engagement between the movable column 10 and the fixed frame 1 provides vertical support for the dispensing platform 11. The threaded transmission between the threaded rod 24 and the fixed seat 22, and the meshing engagement between the toothed block 23 and the rack 21, allow for precise control of the height adjustment range of the dispensing platform 11 via the rotating disc 25, while also enabling stable locking through tooth meshing to prevent accidental sliding of the dispensing platform 11 during dispensing. The sliding engagement between the movable column 10 and the fixed frame 1 ensures the overall structural stability, meeting the operational needs of medical personnel of different heights and improving usability.

[0024] In one embodiment, the fixed base 22 has symmetrically formed second sliding grooves 28, and the toothed block 23 has second sliders 29 fixedly connected to both sides of each other. The second sliders 29 are slidably connected to the inner sidewall of the second sliding groove 28. The inner sidewall of the through groove 20 has symmetrically formed first sliding grooves 26, and the toothed block 21 has first sliders 27 fixedly connected to both sides of each other. The first sliders 27 are slidably connected to the inner sidewall of the first sliding groove 26. The second slider 29 slides along the second slide groove 28, restricting the toothed block 23 to move only laterally along the fixed seat 22, preventing the toothed block 23 from rotating with the threaded rod 24; the first slider 27 slides along the first slide groove 26, restricting the rack 21 to move only vertically along the through groove 20, preventing the rack 21 from deviating or wobbling during the lifting and lowering process; the cooperation between the second slide groove 28 and the second slider 29, and the first slide groove 26 and the first slider 27, provides precise guidance for the movement of the toothed block 23 and the rack 21, ensuring that the toothed block 23 and the rack 21 always maintain a stable meshing state, avoiding jamming during the adjustment process; at the same time, it reduces frictional wear between components, extends the service life of components such as the fixed seat 22, the toothed block 23, and the rack 21, and improves the smoothness and reliability of height adjustment.

[0025] In one embodiment, at least two hooks 12 are fixedly connected to both sides of the dispensing platform 11, and a storage drawer 13 is provided on the fixed frame 1; the upper surface of the dispensing platform 11 is provided with an anti-slip pad layer, which is made of rubber and has anti-slip texture on the surface; a handle 201 is fixedly connected to the disc 25, and an anti-slip rubber sleeve is provided on the outside of the handle 201; the casters 14 are casters with a braking structure, and there are 4 of them, which are respectively set at the four corners of the bottom of the fixed frame 1; Hook 12 can hang items such as disinfectant bottles and garbage bags, while storage drawer 13 is used to store small tools such as syringes and cotton swabs, enabling the categorization of items. The anti-slip mat layer, made of rubber with a high coefficient of friction and anti-slip texture, increases the friction between the medication and the medication platform 11. The handle 201 and its outer anti-slip rubber sleeve facilitate gripping and force application, reducing the difficulty of rotation and adjustment. The casters 14 enable the device to move by rolling, and the braking structure can lock the wheels to prevent slippage during use. Hook 12 and storage drawer 13 improve the organization of items, reduce the time spent searching for items during medication preparation, and improve work efficiency. The anti-slip mat layer on the medication platform 11 prevents medicines, syringes, etc., from slipping during operation, improving safety. The handle 201 and anti-slip rubber sleeve make height adjustment easier and more convenient, suitable for long-term operation. The four casters 14 with brakes combine mobility and stability, facilitating the transfer of the device between wards, treatment rooms, and other scenarios, enhancing the practicality of the device.

[0026] When this utility model is in operation: medical staff can first push the device to the required position using the universal wheels 14 at the bottom of the fixing frame 1, and then lock the braking structure of the universal wheels 14 to ensure that the device is placed stably; To adjust the height of the dispensing platform 11, hold the handle 201 and rotate the disc 25 to rotate the threaded rod 24 within the fixed seat 22. When the threaded rod 24 is rotated outward, the toothed block 23 slides away from the rack 21 along the fixed seat 22 under the guidance of the second slider 29 and the second slide groove 28 until the toothed block 23 separates from the rack 21. At this point, the dispensing platform 11 can be pushed up and down directly. The movable column 10 slides along the fixed frame 1 with the dispensing platform 11. At the same time, the rack 21 moves smoothly up and down within the first slide groove 26 of the through groove 20 via the first slider 27 to achieve coarse height adjustment. Once the height is appropriate, rotate the handle 201 in the opposite direction to rotate the threaded rod 24 inward and push the toothed block 23 back to its original position until the toothed block 23 and the rack 21 are tightly engaged. The locking action of the gear engagement is used to fix the height of the dispensing platform 11, ensuring no shaking during operation. During medication preparation, medical staff can place medications, syringes, and other items on the anti-slip mat of the medication preparation platform 11, using the rubber's anti-slip texture to prevent them from slipping. Small tools such as cotton swabs and grinding wheels can be stored in the storage drawer 13 of the fixed frame 1, while alcohol bottles, garbage bags, and other items can be hung on the hooks 12 on both sides of the medication preparation platform 11 for categorized organization. After the operation is complete, releasing the braking mechanism of the casters 14 allows the device to be pushed to the next usage position. The overall operation is convenient and adaptable to various nursing scenarios.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
