DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] Embodiment 1:
[0032] See also Figure 1 -
[0033] Figure 6 , an infusion anti-pull positioner, comprising a positioning ring 1, such as Figure 1 As shown, the positioning ring 1 has a central hole 2, and the central hole 2 is used for the plastic needle of the infusion tube to pass through, and the positioning ring 1 can be fixed to the plastic needle of the infusion tube;
[0034] like Figure 4 As shown, a plurality of long strip-shaped slide grooves 3 are evenly and radially opened on the inner wall of the positioning ring 1 along its radial direction, a slider 4 is slidably arranged in the slide groove 3, and a clamping plate 6 is connected to the top through a vertical rod 5, and the clamping plate 6 is used to clamp on the bottle mouth of the infusion bottle;
[0035] See also Figure 2 The positioning ring 1 is fixed on the plastic needle, and then a plurality of clamps 6 are clamped and fixed on the mouth of the infusion bottle, so that the infusion bottle and the plastic needle can be stably connected, the stability of the infusion set during use is improved, and the plastic needle can be effectively prevented from loosening or falling out due to being pulled by children;
[0036] like Figure 1As shown, the top surface of the positioning ring 1 is evenly provided with moving notches 15 for allowing the vertical rod 5 to move, so as to facilitate the movement of the vertical rod 5 .
[0037] In this embodiment, six slide grooves 3, sliders 4, uprights 5 and clamps 6 are provided, which are centrally symmetrically distributed to form a stable clamping structure. Of course, for those skilled in the art, the number can also be increased or decreased according to actual needs.
[0038] In the present invention, the movement of the slider 4 in the slide groove 3 is achieved by the rotating ring 10. Specifically, Figure 3 As shown, a rotating ring 10 is rotatably installed in the positioning ring 1, and a plurality of arc-shaped guide grooves 11 are evenly opened on the rotating ring 10 corresponding to the positions of the slide grooves 3. The vertical rods 5 pass through the arc-shaped guide grooves 11. When the rotating ring 10 rotates, the slider 4 can be driven to move by the arc-shaped guide grooves 11 guiding the vertical rods 5.
[0039] like Figure 3 As shown, the outer wall of the rotating ring 10 is meshed with a worm 12, and the worm 12 is fixedly mounted on a driving shaft 13. One end of the driving shaft 13 is rotatably mounted on the inner wall of the positioning ring 1, and the other end extends to the outside of the positioning ring 1 and is fixedly connected to a knob 14. Therefore, by turning the knob 14, the rotating ring 10 can be driven to rotate through the worm 12, thereby controlling the movement of the slider 4.
[0040] See also Figure 5 and Figure 6 In this embodiment, a pull plate 7 is fixedly connected to the bottom end of the vertical rod 5. The pull plate 7 is movably arranged in a plate groove opened inside the slider 4 and is supported downward by a spring 8. In addition, an annular force-sensitive sensor 9 is installed on the inner top wall of the plate groove. The spring 8 is arranged between the force-sensitive sensor 9 and the pull plate 7 and is sleeved on the vertical rod 5. The output end of the force-sensitive sensor 9 is electrically connected to the controller, and the output end of the controller is electrically connected to the input end of the alarm.
[0041] When abnormal pulling occurs, since the position of the positioning ring 1 remains unchanged and the position of the splint 6 on the mouth of the infusion bottle remains unchanged, the pull plate 7 will be pulled upward and compress the spring 8. At this time, the force sensitive sensor 9 detects the pressure and can determine that an abnormal pulling action has occurred. It will then trigger an alarm (such as a warning light, buzzer, etc.) to issue a prompt, making it easy for medical staff to know and intervene in time, thereby effectively preventing adverse consequences caused by further pulling and improving the safety of child care.
[0042] Embodiment 2:
[0043] See also Figure 4 -
[0044] Figure 6On the basis of the first embodiment, in this embodiment, a side tube 16 is fixedly installed on the side of the slider 4 facing the central hole 2, and an inner rod 19 is elastically telescopically provided at the end of the side tube 16. The end of the inner rod 19 is fixedly connected to an inner top plate 20 for abutting against the plastic needle of the infusion tube. Specifically, one end of the inner rod 19 is fixedly connected to the inner top plate 20, and the other end is fixedly connected to the inner plate 17. The inner plate 17 is movably arranged in the side tube 16 and supported by a spring 18.
[0045] By tightening and fixing a plurality of inner top plates 20 on the plastic needle of the infusion tube, the positioning ring 1 can be fixed to the plastic needle of the infusion tube, which not only ensures the stability of positioning, but also the entire positioner can be disassembled for easy reuse;
[0046] Specifically, when in use, first put the positioning ring 1 on the plastic needle, rotate the knob 14 to move the slider 4 inward until the inner top plate 20 is against the plastic needle to fix the position of the positioning ring 1;
[0047] Then, insert the plastic needle into the mouth of the infusion bottle (at this time, the diameter of the virtual circle formed by the plurality of clamps 6 is still larger than the diameter of the bottle mouth). After insertion, rotate the knob 14 again to make the slider 4 continue to move until the clamp 6 holds the bottle mouth tightly. During the continued movement of the slider 4, the spring 18 will be compressed by the inner plate 17 to provide adaptive buffering, which can not only adapt to the position of the slider 4 and ensure that the clamping effect is not affected by the slight size difference of the bottle mouth or the plastic needle, but also further improve the fixing effect of the inner top plate 20 on the plastic needle.
[0048] In addition, by adopting this fixing method, even if the size of the bottle mouth or plastic needle changes slightly, it can be easily adapted, which is more adaptable and improves versatility.
[0049] At the same time, when inserting the plastic needle, due to the annular arrangement of several splints 6, it can also guide the insertion of the plastic needle, avoiding the problem of deflection or skewed insertion of the plastic needle, and effectively ensuring the verticality of the insertion angle.
[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
