Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical care, and particularly relates to an anti - detachment buckle for an infusion set. Background Art
[0002] In infusion care, a medicine bottle (or medicine bag) and an infusion set are required. The head end of the medicine bottle has a rubber stopper. After the insertion tip of the infusion set is inserted into the rubber stopper, subsequent infusion operations can be carried out. Under normal circumstances, the insertion tip generally does not detach from the rubber stopper. However, if it is accidentally pulled by an external force, the insertion tip may be detached. After detachment, the infusion set needs to be replaced, and if not handled in time, blood backflow may occur. Therefore, an anti - detachment buckle can be designed for anti - detachment limitation.
[0003] Currently, there are also various structural designs for anti - detachment buckles. The more common one is the U - shaped structure. The insertion tip penetrates into the center of the anti - detachment buckle. The two sides of the U - shaped structure are upward - set hooks, which are used to clamp the bottle mouth part through the hooks, thereby completing the limit fixation. Although this structural design is simple, the anti - detachment effect of such products is still not ideal enough. Content of the Utility Model
[0004] In view of the above problems, the purpose of the utility model is to provide an anti - detachment buckle for an infusion set, aiming to solve the above - mentioned technical problems.
[0005] The utility model adopts the following technical scheme:
[0006] The anti - detachment buckle for the infusion set includes two ring - groove clamping plates, namely a first ring - groove clamping plate and a second ring - groove clamping plate. The ends of the two ring - groove clamping plates are rotationally connected through a connecting piece, and the head ends are locked through a locking mechanism. Each ring - groove clamping plate includes an annular top plate, a bottom plate, and an arc - shaped side plate. The inner edge of the bottom plate of each ring - groove clamping plate sinks and integrally forms a fan - shaped dragging plate. The cross - section of the fan - shaped dragging plate is L - shaped, the inner edge of the fan - shaped dragging plate is an arc, and there is an avoidance area between the same ends of the two fan - shaped dragging plates.
[0007] Further, a pair of hooks are formed at the head end of the first ring - groove clamping plate, and a hinge part is formed at the head end of the second ring - groove clamping plate. The locking mechanism includes a rotating plate hinged to the hinge part. A pulling plate is rotatably arranged between the two rotating plates. A T - shaped rod is connected to the middle of the pulling plate, and the two ends of the T - shaped rod are used to be clamped into the hooks. A 7 - shaped operating rod is also fixed on the rotating plate.
[0008] Further, there is also a convex platform on the surface of the side plate of the second annular groove plate, and a safety hook for limiting the 7 - shaped operating rod is rotatably arranged on the convex platform.
[0009] Further, the T - shaped rod is screwed to the pulling plate.
[0010] The beneficial effects of the present utility model are as follows: By designing a pair of switchable ring groove clamping plates, the mouth part of the medicine bottle can be clamped between the top plate and the bottom plate of the ring groove clamping plates. This clamping method is very firm. At the same time, a fan-shaped dragging plate is integrally formed downward on the bottom plate of the ring groove clamping plate, providing a certain accommodation space for the wing plate of the intubation nozzle, limiting the wing plate above the inner upper part of the fan-shaped dragging plate. At the same time, the area between the two ends of the fan-shaped dragging plate is an avoidance area for avoiding the gas branch pipe of the intubation nozzle. Therefore, through this structural design, it can adapt to the shape of the intubation nozzle of the infusion set, well limit the intubation nozzle, and has a good anti-detachment effect.

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0016] In order to illustrate the technical solutions described in the present utility model, the following will be illustrated by specific embodiments.
[0017] As Figures 1 - 3 shown, the infusion set anti-detachment buckle provided in this embodiment includes two ring groove clamping plates 1, namely the first and the second. The ends of the two ring groove clamping plates 1 are rotatably connected by a connecting member 2, and the head ends are locked by a locking mechanism 3. The ring groove clamping plate 1 includes an annular top plate 11, a bottom plate 12 and an arc-shaped side plate 13. The inner edge of the bottom plate of each ring groove clamping plate 1 sinks and integrally forms a fan-shaped dragging plate 4. The cross-section of the fan-shaped dragging plate 4 is L-shaped, the inner edge of the fan-shaped dragging plate 4 is an arc, and the area between the same ends of the two fan-shaped dragging plates 4 is an avoidance area 5.
[0018] The neck of the insertion tip of the infusion set has horizontal wing plates, and a gas branch pipe is closely arranged above or below the wing plates. In this structure, the main structure of the anti-disengagement buckle of the infusion set is a pair of annular groove clamping plates, which are connected by a rotating shaft at the end, and the head end is provided with a locking mechanism. The specific locking method is not limited in the embodiment. As a specific structure, a pair of hooks 14 are formed at the head end of the first annular groove clamping plate, and a hinge portion 15 is formed at the head end of the second annular groove clamping plate. The locking mechanism 3 includes a rotating plate 31 hinged to the hinge portion 15, a pulling plate 32 is rotatably arranged between the two rotating plates 31, a T-shaped rod 33 is connected to the middle of the pulling plate 32, and both ends of the T-shaped rod 33 are used to be clamped into the hooks 14. A 7-shaped operating rod 34 is also fixed on the rotating plate 31. During operation, first open the two annular groove clamping plates, buckle the annular groove clamping plates on the bottle mouth part of the medicine bottle (there is a rubber stopper with an exposed bottom in the bottle mouth part), after clamping both ends of the T-shaped rod into the hooks, rotate the 7-shaped operating rod backward until it is close to the annular groove clamping plate. At this time, the T-shaped rod is tightened, and then the two annular groove clamping plates are locked, and the operation is very simple. In order to prevent the 7-shaped operating rod from loosening, as shown in the figure, there is also a boss 16 on the side plate surface of the second annular groove plate, and a safety hook 17 for limiting the 7-shaped operating rod 34 is rotatably arranged on the boss 16. By rotating the safety hook 17 to the outside of the 7-shaped operating rod, the 7-shaped operating rod is prevented from rotating back, ensuring stability. Here, the safety hook 17 has a rotational resistance and does not rotate freely.
[0019] Further, the T-shaped rod 33 is screwed onto the pulling plate 32, and the tightening force of the annular groove clamping plate can be adjusted.
[0020] Through the above structural design, the structure of this embodiment can clamp the bottle mouth part of the medicine bottle between the top plate and the bottom plate of the annular groove clamping plate, and its height is adapted to the thickness of the bottle mouth part. This clamping method is very firm, and it will not fall off as long as the annular groove clamping plate does not loosen. At the same time, a fan-shaped drag plate is integrally formed downward on the bottom plate of the annular groove clamping plate, and its cross-section is L-shaped, so as to form a thickness space to provide a certain accommodation space for the wing plate of the insertion tip. It is not required that the wing plate of the insertion tip completely abuts against the bottom surface of the rubber stopper when inserting the insertion tip, and the wing plate is limited above the fan-shaped drag plate.
[0021] Particularly, in this structure, the area between the two ends of the fan-shaped drag plate is an avoidance area for avoiding the gas branch pipe of the insertion tip of the infusion set. Therefore, through this structural design, it can adapt to the shape of the insertion tip of the infusion set and various models of infusion sets, well limit the insertion tip, and has a good anti-disengagement effect and wide application.
[0022] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
