[0027] Example 1

[0028] Please refer to Figures 1-4 , an infusion set fixing device, including a support column 1, a telescopic rod 2 is slidably connected to the top end of the support column 1, a plurality of limit grooves are opened inside the telescopic rod 2, a slide seat 3 is slidably connected to the top end of the outer side of the telescopic rod 2, a clamping mechanism is provided inside the slide seat 3, a limit ring 4 is fixed to the outer side of the telescopic rod 2 and below the slide seat 3, and an adjustment seat 5 is slidably connected to the outer side of the telescopic rod 2 and below the limit ring 4;

[0029] Specifically, when one end of the sealing mouth of the bottle stopper is placed above the limiting ring 4, the sliding seat 3 is adjusted in height according to the size of the bottle stopper, and then the clamping mechanism limits and fixes different bottle stoppers, thereby improving the adaptability of the device to bottle stoppers of different sizes. When the puncture head is plugged into the bottle stopper, the drip pot in the infusion set is placed above the adjusting seat 5 for clamping, so that the puncture head and the bottle stopper are not separated due to accidental pulling of the infusion set, thereby increasing the stability of the infusion set.

[0030] The clamping mechanism includes a clamping plate 11, a threaded rod 12, a transmission rod 13 and a hand-turned cylinder 14. The transmission rod 13 is rotatably connected to the interior of the slide 3. Threaded rods 12 are fixed on both sides of the outer side of the transmission rod 13. The two threaded rods 12 rotate in opposite directions. The outer sides of the threaded rods 12 are threadedly connected to the clamping plate 11. The ends of the two clamping plates 11 that are close to each other are fixed with anti-slip pads.

[0031] Furthermore, when it is necessary to position bottle corks of different sizes, the hand cylinder 14 is rotated to drive the transmission rod 13 and the threaded rod 12 to rotate synchronously, so that the threaded rod 12 drives the two clamping plates 11 and the anti-slip pad to position and fix the bottle corks, thereby facilitating the fixing of bottle corks of different sizes.

[0032] A limit buffer assembly is provided at the top of the adjustment seat 5, which includes a U-shaped snap ring 6, a limit rod 7 and a buffer spring 8. The left end of the interior of the adjustment seat 5 is slidably connected with a plurality of limit rods 7. The top of the limit rod 7 is fixed with a U-shaped snap ring 6, and the outer side of the limit rod 7 is sleeved with a buffer spring 8. The top of the buffer spring 8 is fixed to the U-shaped snap ring 6, and the bottom end of the buffer spring 8 is fixed to the adjustment seat 5.

[0033] Furthermore, by passing the drip pot through the adjustment seat 5 and placing it above the U-shaped snap ring 6, when the patient accidentally pulls the infusion set while moving, the infusion set drives the U-shaped snap ring 6 to apply pressure downward, and then the U-shaped snap ring 6 drives the limit rod 7 to compress the buffer spring 8. At this time, the adjustment seat 5 and the U-shaped snap ring 6 effectively limit the drip pot of the infusion set, which is beneficial to increasing the stability of the infusion set and preventing the puncture head from separating from the bottle stopper, resulting in air ingress and blood backflow;

[0034] The right end of the inside of the adjustment seat 5 is slidably connected with a pin 9, one end of the pin 9 is slidably connected to the corresponding limit groove, and a tension spring 10 is sleeved on the outer side of the pin 9. By pulling the pin 9, the adjustment seat 5 and the U-shaped clamping ring 6 are adjusted according to the height of the drip pot of the infusion set, and then the tension spring 10 drives the pin 9 to engage with the corresponding limit groove, so as to effectively limit the infusion set.

[0035] The use process of the infusion set fixing device provided by the utility model is as follows:

[0036] Working principle: When one end of the sealing mouth of the bottle stopper is placed above the limiting ring 4, the sliding slide 3 is adjusted to the height according to the size of the bottle stopper, and then the transmission rod 13 and the threaded rod 12 are driven to rotate synchronously by rotating the hand cylinder 14, so that the threaded rod 12 drives the two splints 11 and the anti-slip pad to limit and fix the bottle stopper, so as to fix bottle stoppers of different sizes, and then the puncture head is plugged into the bottle stopper, and the drip pot is passed through the adjusting seat 5 and placed above the U-shaped clamping ring 6. When the patient accidentally pulls the infusion pump while moving, the infusion pump drives the U-shaped clamping ring 6 to apply pressure downward, and then the U-shaped clamping ring 6 drives the limiting rod 7 to compress the buffer spring 8. At this time, the adjusting seat 5 and the U-shaped clamping ring 6 effectively limit the drip pot of the infusion pump, which is beneficial to increase the stability of the infusion pump and prevent the puncture head from separating from the bottle stopper.
