The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1

[0024] See also Figure 1~Figure 3 As shown, the utility model provides an anti-pull infusion buckle, including an elastic base strip 1, a detachable bottleneck buckle 2 and a detachable plastic needle buckle 3, the detachable bottle buckle 2 is respectively arranged at the top and the lower section of the elastic base strip 1, and is used to be detachably buckled on the outer wall of the bottleneck of the infusion bottle and the outside of the plastic needle of the infusion device respectively; the detachable bottleneck buckle 2 includes an arc-shaped first plastic sheet 2a and a second plastic sheet 2b, one ends of the first plastic sheet 2a and the second plastic sheet 2b are respectively connected to the left and right sides of the top of the elastic base strip 1, and the other ends of the first plastic sheet 2a and the second plastic sheet 2b are detachably connected by a snap buckle; the detachable plastic needle buckle 3 includes a third plastic sheet 3a and a fourth plastic sheet 3b, one ends of the third plastic sheet 3a and the fourth plastic sheet 3b are respectively connected to the left and right sides of the lower section of the elastic base strip 1, and the other ends of the third plastic sheet 3a and the fourth plastic sheet 3b are detachably connected by a snap buckle.

[0025] In this embodiment, by improving the design of the anti-pull infusion buckle, the elastic base strip 1 can elastically expand and contract under the action of external pulling force. Before infusion, after the plastic needle of the plastic needle bottle stopper piercer is inserted into the bottle stopper of the infusion bottle, first operate the first plastic sheet 2a and the second plastic sheet 2b to embrace the outer wall of the bottleneck of the infusion bottle, further apply force to make the first plastic sheet 2a and the second plastic sheet 2b fasten, and then pull down the detachable plastic needle buckle 3, operate the third plastic sheet 3a and the fourth plastic sheet 3b to embrace the plastic needle below, and further apply force to make the third plastic sheet 3a and the fourth plastic sheet 3b fasten, so that the entire infusion buckle elastically tightens the bottleneck of the infusion bottle and the plastic needle in the vertical direction, and the upper and lower fasteners respectively clamp the bottleneck of the infusion bottle and the plastic needle. The structural design is simple and easy to operate. It is elastically fastened in multiple dimensions with the elastic base strip as the main body. It has better buffering force when the plastic needle bottle stopper piercer is subjected to instantaneous pulling force, and can effectively prevent adverse events such as pulling off the infusion device and pulling down the infusion stand.

[0026] There are many designs of buckle components. In the infusion scenario, the convenience of buckle operation and the stability of buckle structure need to be considered. In this embodiment, one of the first plastic sheet 2a and the second plastic sheet 2b is provided with an upper clamping groove 4, and the other is provided with an upper clamping hook 5 for matching hooking and clamping on the upper clamping groove 4. During operation, the clamping hook is inserted from the bottom of the clamping groove for clamping. Correspondingly, the third plastic sheet 3a and the fourth plastic sheet 3b are arc-shaped, and one of the third plastic sheet 3a and the fourth plastic sheet 3b is provided with a lower clamping groove 6, and the other is provided with a lower clamping hook 7 for matching hooking and clamping on the lower clamping groove 6. The connecting line between the upper clamping groove 4 and the lower clamping groove 6 is in a cross state with the connecting line between the upper clamping hook 5 and the lower clamping hook 7, and the clamping hook force application position is more uniform.

[0027] In order to further enhance the holding force of the detachable bottle neck buckle 2 and the detachable plastic needle buckle 3, a plurality of triangular teeth 8 may be evenly distributed on the inner walls of the first plastic sheet 2a and the second plastic sheet 2b, with the tips of the triangular teeth 8 pointing to the center of the embracing area of ​​the first plastic sheet 2a and the second plastic sheet 2b, for holding the outer wall of the bottleneck of the infusion bottle. Accordingly, a plurality of silicone protrusions 9 are evenly distributed on the inner walls of the third plastic sheet 3a and the fourth plastic sheet 3b to flexibly squeeze the outer wall of the plastic needle and enhance friction and anti-slip performance.

[0028] Preferably, a hanging portion 10 for an infusion needle is provided on the outer wall of the fourth plastic sheet 3b, so as to facilitate hanging and placing the infusion tube tip after exhausting air, and to prevent the nurse from randomly hanging it on the bed.

[0029] Example 2

[0030] like Figures 4 and 5 As shown, this embodiment makes one of the optimized designs on the basis of the above embodiments, and the buckle structure of the detachable bottleneck buckle 2 is made into another configuration. In this embodiment, one of the first plastic sheet 2a and the second plastic sheet 2b is provided with a first offset card slot 11 with an opening facing upward, and the other is provided with a second offset card slot 12 with a snap-on opening facing downward for matching the first offset card slot 11 for overlapping and clamping. This design makes the two plastic sheets thinner and the overlapping and clamping very stable.

[0031] As one of the embodiments, the detachable plastic needle buckle 3 is modified in another way, the third plastic sheet 3a and the fourth plastic sheet 3b are in a straight line, the third plastic sheet 3a is provided with a plurality of holes distributed along the length extension direction of the third plastic sheet 3a, the fourth plastic sheet 3b is provided with a plug for matching and buckling into the holes so that the third plastic sheet 3a and the fourth plastic sheet 3b can hold the plastic needle of the infusion set tightly, and many plastic needles have a laterally protruding baffle in the middle part. This design allows the two plastic sheets to be buckled on the lower part of the transverse baffle in the middle of the plastic needle. When the plastic needle is pulled downward, the plastic needle is not easy to loosen due to the obstruction of the baffle.

[0032] As another improved design, in order to further enhance the anti-pulling performance of the infusion buckle, it is necessary to flexibly release the instantaneous pulling force. In this embodiment, a coil spring seat 13 is installed at the lower end of the elastic base strip 1, and a coil spring 14 is installed on the coil spring seat 13. The free end of the coil spring 14 is externally arranged and provided with an infusion tube hook 15. A section of the infusion tube of the infusion device located below the plastic needle can be slightly bent and then put on the infusion tube hook 15 at the free end of the coil spring 14. When encountering unexpected instantaneous pulling force, the coil spring 14 absorbs energy to protect the plastic needle inserted into the bottle stopper from being pulled off.
