Description

Technical Field

[0001] The utility model belongs to the technical field of medical care, and in particular relates to a medical infusion stand. Background Art

[0002] An infusion stand is a medical device commonly used by medical staff to assist infusion. Multiple hooks are fixed on the infusion stand to hang infusion bottles and infusion bags used for infusion, so that the infusion bottles and infusion bags can maintain a certain infusion height during the infusion process to facilitate the flow of the medicine.

[0003] However, the hooks fixed on traditional infusion stands are usually not hidden. For example, the hooks used in an infusion stand in an existing public patent (application number CN202321159676.6) are exposed to the outside and cannot be hidden. This means that the hooks are in an exposed state during use. Especially when such infusion stands are used in infusion halls, the number of hooks will increase accordingly due to the large number of them. In addition, with frequent pedestrian traffic, pedestrians can easily scratch the hooks, causing the infusion stand to fall over, thereby endangering safety.

[0004] For this reason, we propose a medical infusion stand to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 A medical infusion stand comprises a moving seat 1, a supporting slide 2 is fixedly arranged on the moving seat 1, a supporting rod 3 is slidably connected to the supporting slide 2, a rack 4 is fixedly arranged on the supporting rod 3, a gear 5 meshing with the rack 4 is rotatably arranged on the supporting slide 2, and a self-locking driving mechanism 6 matched with the gear 5 is arranged on the supporting slide 2;

[0025] The self-locking drive mechanism 6 is composed of a worm 61 and a worm wheel 62. A drive box 13 is fixedly arranged on one side of the support slide 2, and one end of the transmission shaft of the gear 5 extends into the drive box 13 and is fixedly sleeved with the worm wheel 62. The worm 61 is rotatably arranged in the drive box 13, and the worm 61 is meshed with the worm wheel 62. The upper end of the worm 61 passes through the drive box 13 and is fixedly connected with the first turning handle 14. The unfolded helix angle of the worm 61 is smaller than the friction angle between the worm 61 and the worm wheel 62. Through the transmission cooperation of the worm 61 and the worm wheel 62, it is convenient for medical staff to control the rotation of the gear 5 through the first turning handle 14, and then under the cooperation of the rack 4, the support rod 3 can be controlled to be lifted and lowered to realize the height control of the infusion stand. The unfolded helix angle design of the worm 61 can realize the self-locking between the worm 61 and the worm wheel 62 to avoid the tediousness of manual locking.

[0026] A storage shell 7 is fixedly provided at the upper end of the support rod 3, and a slide plate 8 is slidably connected in the storage shell 7. The storage shell 7 is designed as a whole in a cylindrical shape, and a rubber protective sleeve 18 is fixedly sleeved on the storage shell 7. The shape design of the storage shell 7 makes the whole relatively round and not easy to be scratched by pedestrians. The design of the rubber protective sleeve 18 can utilize its own elasticity to avoid hard collision with pedestrians when the infusion stand is overturned, so as to provide a certain degree of protection;

[0027] A plurality of hooks 9 are fixedly provided on the slide plate 8, and a docking rod 10 corresponding to the hook 9 is fixedly provided in the storage shell 7, the slide plate 8 is slidably connected with each docking rod 10, an opening 11 corresponding to the hook 9 is provided on the lower side of the storage shell 7, a docking block 16 is fixedly provided at the lower end of the docking rod 10, and a docking groove 17 corresponding to the hook 9 is provided on the docking block 16, and the hook 9 can be docked with it when it is folded and hidden through the provided docking block 16 and the docking groove 17, so that the hook 9 can form a closed loop to prevent the hung infusion bottle or infusion bag from being unhooked;

[0028] The storage shell 7 is provided with a self-locking lifting control mechanism 12 that cooperates with the slide plate 8. The self-locking lifting control mechanism 12 consists of a screw rod 121 and a second handle 122. The screw rod 121 is rotatably arranged in the storage shell 7, and the slide plate 8 is threadedly connected to the screw rod 121. One end of the screw rod 121 passes through the storage shell 7 and is fixedly connected to the second handle 122. The thread lead angle of the screw rod 121 is less than the equivalent friction angle. By setting the second handle 122, the screw rod 121 can be controlled to rotate, so that the lifting and lowering of the slide plate 8 can be realized, and then the lifting and lowering of each hook 9 can be controlled to facilitate hiding the hook 9. The thread lead angle design of the screw rod 121 can achieve self-locking between the screw rod 121 and the slide plate 8 to avoid the tediousness of manual locking. An operating port 15 is opened on the support rod 3, and the lower end of the screw rod 121 extends into the operating port 15 and is fixedly connected to the second handle 122. The design of the operating port 15 can reduce the use height of the second handle 122 for easy operation by medical staff.

[0029] The operating principle of the utility model is now described as follows:

[0030] When using the infusion stand, the second turning handle 122 can be manipulated so that the second turning handle 122 controls the screw rod 121 to rotate. With the rotation of the screw rod 121, the slide plate 8 can drive each hook 9 to move down and extend out of the opening 11, so that the hook 9 is exposed. Then, the medical staff can hang the infusion bottle or infusion bag that needs infusion on the hook 9, and then, the second turning handle 122 is rotated in the opposite direction to make the screw rod 121 reverse, so that the slide plate 8 drives each hook 9 to move up and hide in the storage shell 7, and the hook 9 will dock with the corresponding docking block 16 to form a closed loop after entering the storage shell 7, which can effectively prevent the hung infusion bottle or infusion bag from being unhooked. Then, the medical staff can use the infusion tube to connect the infusion bottle or infusion bag to perform infusion work;

[0031] When the height of the infusion stand needs to be adjusted, the first handle 14 is turned, and the first handle 14 will control the rotation of the worm 61. Under the transmission cooperation of the worm wheel 62, the gear 5 will rotate synchronously. By controlling the gear 5 to rotate forward or reverse in coordination with the rack 4, the support rod 3 can be controlled to be raised and lowered, thereby realizing the height adjustment of the infusion stand.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
