Detailed Implementation
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0026] Example 1
[0027] Please see Figures 1-3 A telescopic infusion stand includes a suspension rod 100, a sleeve rod 200 slidingly fitted on the lower part of the suspension rod 100, and a pull rope box 700 fixedly installed on the upper part of the sleeve rod 200. A worm gear 702 and a worm wheel 705 are rotatably installed inside the pull rope box 700, with the worm gear 702 meshing with the worm wheel 705. A gear 706 is fixedly installed on the worm wheel shaft 704 of the worm wheel 705. A recessed rack 101 is provided on the sleeve rod 200, and one side of the gear 706 passes through the sleeve rod 200 and meshes with the rack 101. Pull ropes a500 and b600 are fixedly connected to the worm shaft 701 of the worm gear 702, with the upper ends of pull ropes a500 and b600 respectively wound around the worm shaft 701; and the lower ends of pull ropes a500 and b600 respectively extend downwards through the pull rope box 700.
[0028] In practice, the upper ends of pull rope a500 and pull rope b600 are wound in opposite directions on the worm shaft 701. Pull rope a500 and pull rope b600 can control the forward and reverse rotation of the worm shaft 701 respectively; by different rotation directions, the gear 706 is driven to climb or descend on the rack 101.
[0029] In implementation, a partition 703 is fixedly sleeved on the worm shaft 701, and the partition 703 is located between the upper end of the pull rope a500 and the upper end of the pull rope b600. The partition 703 can separate the pull rope a500 and the pull rope b600, preventing the pull rope a500 and the pull rope b600 from getting tangled together when the worm shaft 701 rotates.
[0030] In implementation, such as Figure 1 As shown, counterweight balls 601 are fixedly connected to the lower ends of pull ropes a500 and b600, respectively. Pull ropes a500 and b600 are different colors, such as red and green; pulling the red rope raises the rope, and pulling the green rope lowers it. A hook 201 is fixedly connected to the lower end of the lever 200. The counterweight balls 601 increase the weight on the lower ends of pull ropes a500 and b600, keeping the ropes straight and preventing them from getting tangled in the hook 201.
[0031] In implementation, the boom 100 can be directly fixed to the ceiling to form a fixed infusion stand. Alternatively, a ball 301 can be fixedly connected to the upper end of the boom 100, and the ball 301 is movably installed inside a ball seat 300. Then, the ball seat 300 is fixed to the ceiling, allowing the boom 100 to swing.
[0032] Example 2
[0033] Unlike Example 1, as Figure 3 As shown, a permanent magnet 400 is fixedly connected to the top of the ball seat 300, and a ball bearing 401 is movably mounted on the top of the permanent magnet 400. It also includes an iron plate 800, which is fixedly mounted on the ceiling. The permanent magnet 400 can be magnetically attracted to the surface of the iron plate 800. It is important to note that the permanent magnet 400 is a powerful neodymium iron boron magnet, and the gap between the permanent magnet 400 and the iron plate 800 should be as small as possible (less than 0.5mm). This ensures sufficient attraction while allowing for flexible rolling, preventing it from falling due to excessive force. A larger permanent magnet 400 can be selected, ideally with an attraction force of over 10kg, to ensure safety.
[0034] During implementation, the telescopic infusion stand can be moved freely during use through the cooperation of permanent magnet 400, ball bearing 401 and iron plate 800. If the iron plate 800 is used to cover the ceiling of the infusion room and toilet, patients can move around and go to the toilet while receiving infusions, which is very convenient.
[0035] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application 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 specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
