Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an infusion stent. Background Technology

[0002] Currently, most hospital wards have sliding rails installed on the ceiling. The infusion stand is suspended on the rail and can move along the rail so that the patient can adjust the infusion position according to the actual needs. At the same time, in order to facilitate the hanging of medicine bottles by patients of different heights and medical staff, the infusion stand is mostly a telescopic structure with an outer tube covering an inner tube. After the inner tube and the outer tube slide relative to each other, they are locked by rotating the threaded fitting at the connection between the two for fixed use.

[0003] However, the threaded assembly of this type of infusion stent is mostly located in the middle. When the infusion stent is suspended on the slide rail, the threaded assembly is in a high position, which is usually out of reach for ordinary people. Generally, the infusion stent needs to be removed from the slide rail before it can be extended and retracted, which is inconvenient to operate. Utility Model Content

[0004] In view of this, the present invention provides an infusion stent to solve the problem that in the prior art, the threaded assembly of the infusion stent is mostly located in the middle. When the infusion stent is suspended on the slide rail, the threaded assembly is located at a high position, which is usually out of reach for ordinary people. Generally, the infusion stent needs to be removed from the slide rail for extension and retraction adjustment, which is inconvenient to operate.

[0005] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes an infusion stent, comprising an outer tube, an inner tube, a rotating shaft, a knob, and a locking assembly. The inner tube is slidably connected within the outer tube, and the bottom end of the inner tube extends through the bottom end of the outer tube and is fixedly mounted on a base. A hook is provided on the side wall of the base. The rotating shaft is coaxially disposed within the inner tube, and the bottom end of the rotating shaft extends through the base to the outside and is threadedly connected to the base. The knob is fixedly mounted on the exposed end of the rotating shaft. The locking assembly is disposed at the top end of the inner tube. Rotating the rotating shaft can drive the locking assembly to expand and compress the inner side wall of the outer tube, thereby restricting the relative sliding between the inner and outer tubes.

[0006] Preferably, the locking assembly includes a deformable tube made of elastic material and a pressing block. The deformable tube is fixedly connected to the top end of the inner tube and is coaxially arranged with the inner tube. The inner diameter of the deformable tube gradually decreases towards one end. Several notches are evenly distributed circumferentially on the outer side wall of the top end of the deformable tube. The notches are strip-shaped and arranged along the axial direction of the deformable tube. The multiple notches divide the top end of the deformable tube into multiple deformable parts. The top end of the rotating shaft passes through the deformable tube. The pressing block is coaxially fixed on the top end of the rotating shaft. Rotating the rotating shaft can drive the pressing block to push the inner side wall of the deformable tube, causing the multiple deformable parts to expand outward.

[0007] Preferably, the inner diameter of the deformable tube gradually decreases from its bottom end to its top end, and the extrusion block is frustum-shaped with its wide end fixedly connected to the rotating shaft.

[0008] Preferably, a guide tube is coaxially fixed to the bottom end of the deformable tube, the guide tube is fixedly sleeved inside the top end of the inner tube, and the top end of the rotating shaft passes through the guide tube into the deformable tube and is slidably connected to the guide tube.

[0009] Preferably, the outer diameter of the deformable tube is the same as the outer diameter of the inner tube.

[0010] Preferably, the deformable tube, extrusion block, base, and knob are all made of plastic.

[0011] Preferably, the rotating shaft has a hollow structure.

[0012] Preferably, the knob has an anti-slip structure on its periphery.

[0013] Preferably, the shaft, inner tube, and outer tube are all made of metal.

[0014] Preferably, there are four hooks, which are evenly distributed around the circumference of the base.

[0015] Implementing the embodiments of this utility model will have the following beneficial effects:

[0016] After adopting the above-mentioned infusion stent, during use, the top of the outer tube is first hung on the slide rail so that the infusion stent can move along the slide rail. Under normal circumstances, the locking component is in the expanded state, and the locking component partially squeezes the inner wall of the outer tube, so that the inner tube and the outer tube are relatively fixed. At this time, medical staff can hang the medicine bottle on the hook for the convenience of patients receiving infusion. When it is necessary to adjust the horizontal height of the hook, simply turn the knob to make the rotating shaft move axially through the thread, driving the locking component to retract and disengage from the inner wall of the outer tube. Without the restriction of the locking component, the inner tube can be slid to adjust the horizontal height of the hook. Finally, simply reverse the knob to drive the locking component to expand again, which can restrict the relative sliding of the inner tube and the outer tube again. This allows users to adjust the extension and retraction of the infusion stent without removing it, reducing the difficulty of operation and improving the user experience.

[0024] 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 invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0025] 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 the present invention. 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.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown, an infusion stent includes an outer tube 1, an inner tube 2, a rotating shaft 3, a knob 4, and a locking assembly 5. The inner tube 2 is slidably connected to the outer tube 1, with its bottom end extending through the bottom end of the outer tube 1 and fixedly mounted on a base 21. A hook 22 is provided on the side wall of the base 21. The rotating shaft 3 is coaxially mounted within the inner tube 2, with its bottom end penetrating the base 21 to the outside and threadedly connected to it. The knob 4 is fixedly mounted on the exposed end of the rotating shaft 3. The locking assembly 5 is located at the top of the inner tube 2. In use, the top of the outer tube 1 is first hung on a slide rail so that the infusion stent can move along the slide rail. Under normal conditions, the locking assembly 5 is in an expanded state, partially compressing the outer tube. The inner wall of the outer tube 1 fixes the inner tube 2 and the outer tube 1 relatively. At this time, medical staff can hang the medicine bottle on the hook 22 for the convenience of the patient to receive infusion. When it is necessary to adjust the horizontal height of the hook 22, simply turn the knob 4 to make the rotating shaft 3 move axially through the thread, which drives the locking component 5 to retract and disengage from the inner wall of the outer tube 1. Without the restriction of the locking component 5, the inner tube 2 can be slid to adjust the horizontal height of the hook 22. Finally, simply reverse the knob 4 to drive the locking component 5 to expand again, which can restrict the relative sliding of the inner tube 2 and the outer tube 1 again. This allows the user to adjust the infusion stand without removing it, reducing the difficulty of operation and improving the user experience.

[0028] Specifically, the bottom of the aforementioned components refers to the end of the component facing the ground when the infusion stand is suspended in use, while the top refers to the opposite.

[0029] In one embodiment, the locking assembly 5 includes a hollowed-out limiting frame and an airbag. The limiting frame is fixedly upside down on the top end of the inner tube 2 and together with the top end of the inner tube 2, it surrounds the airbag. When the rotating shaft 3 rotates and lifts, the top end of the rotating shaft 3 will squeeze the airbag, causing the airbag to deform locally and protrude from the side wall opening of the limiting frame. The protruding end of the airbag will abut against the inner side wall of the outer tube 1, thereby limiting the relative sliding between the inner tube 2 and the outer tube 1 through the airbag (not shown in the figure).

[0030] Furthermore, the locking assembly 5 includes a deformable tube 6 made of elastic material and a pressing block 7. The deformable tube 6 is fixedly connected to the top end of the inner tube 2 and is coaxially arranged with the inner tube 2. The inner diameter of the deformable tube 6 gradually decreases towards one end. Several notches 61 are evenly distributed circumferentially on the outer wall of the top end of the deformable tube 6. The notches 61 are strip-shaped and arranged along the axial direction of the deformable tube 6. The multiple notches 61 divide the top end of the deformable tube 6 into multiple deformable parts 62. The top end of the rotating shaft 3 passes through the deformable tube 6, and the pressing block 7 is coaxially fixed on the top end of the rotating shaft 3. In use, it can be first... Rotate knob 4 to drive the pressing block 7 to move axially and disengage from the inner wall of the deformable tube 6 via shaft 3. This causes several deformable parts 62 to retract and disengage from the inner wall of the outer tube 1. Then, slide the inner tube 2 to adjust the hook 22 to a suitable height. Then, reverse knob 4 to drive the pressing block 7 to move axially via shaft 3. Use the pressing block 7 to push against the inner wall of the deformable tube 6, causing several deformable parts 62 to expand outward and press against the inner wall of the outer tube 1. This restricts the relative sliding between the inner tube 2 and the outer tube 1 through frictional resistance, helping the hook 22 to be positioned and used.

[0031] Furthermore, the inner diameter of the deformable tube 6 gradually decreases from its bottom end to its top end. The extrusion block 7 is frustum-shaped, and its wide end is fixedly connected to the rotating shaft 3. When the rotating shaft 3 rotates and rises through the thread, the side wall of the extrusion block 7 will fit against the inner wall of the deformable tube 6 and gradually slide upward along the inner wall of the deformable tube 6. The contact area between the extrusion block 7 and the inner wall of the deformable tube 6 is increased by the inclined surface on the outer side of the extrusion block 7, so that the several deformable parts 62 are evenly stressed.

[0032] Furthermore, a guide tube 8 is coaxially fixed to the bottom end of the deformable tube 6. The guide tube 8 is fixedly sleeved inside the top end of the inner tube 2. The top end of the rotating shaft 3 passes through the guide tube 8 into the deformable tube 6 and is slidably connected with the guide tube 8, so as to improve the installation stability of the rotating shaft 3 through the guide tube 8.

[0033] Furthermore, the outer diameter of the deformable tube 6 is the same as that of the inner tube 2, so as to reduce the distance between the outer wall of the deformable part 62 and the inner wall of the outer tube 1, control the range of deformation expansion of the deformable part 62, reduce the upward stroke of the rotating shaft 3 and the number of rotations of the knob 4, and reduce the operation time.

[0034] Furthermore, the deformable tube 6, the compression block 7, the base 21, and the knob 4 are all made of plastic, and the rotating shaft 3 has an internal hollow structure, which reduces the overall weight of the infusion stand and reduces the burden on the slide rail.

[0035] Furthermore, the knob 4 is provided with an anti-slip structure 41 on its periphery to increase the surface roughness of the knob 4, making the knob 4 more responsive and preventing slippage.

[0036] Furthermore, the pivot 3, inner tube 2, and outer tube 1 are all made of metal to enhance the structural strength of the infusion stent's frame, thus ensuring stable placement of the medicine bottle.

[0037] Furthermore, four hooks 22 are provided and are evenly distributed along the circumference of the base 21.

[0038] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model 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 utility model. Although this 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 specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
