[0040] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] Example 1

[0042] like Figures 2-5 As shown, this embodiment provides an infusion tube fixator, including: an elastic ring 1, a fixing base 2, an air bladder 3, and multiple protrusions 4.

[0043] The elastic ring 1 has an opening on one side and a receiving cavity 11 inside. The inner wall of the elastic ring 1 has a plurality of sliding grooves 12 that communicate with the receiving cavity 11. An airbag 3 is provided in the receiving cavity 11. A protrusion 4 is movably provided in each sliding groove 12. The side of the protrusion 4 that is close to the receiving cavity 11 is connected to the airbag 3, and the side that is away from the receiving cavity 11 protrudes out of the inner wall of the elastic ring 1.

[0044] A fixing seat 2 is provided on the outer wall opposite to the opening, and a slot 21 adapted to the infusion tube is provided on the fixing seat 2. For example, the slot 21 includes an inlet portion and an annular portion that are connected. The upper part of the slot 21 is the inlet portion, and the lower part is the annular portion. The diameter of the inlet portion is smaller than the diameter of the annular portion, and the diameter of the annular portion is slightly larger than the diameter of the infusion tube. The size of the inlet portion is slightly smaller than the diameter of the infusion tube. The inlet portion is made of an elastic material, which can elastically open and automatically return to its original position. In use, the infusion tube enters the annular portion after passing through the inlet portion.

[0045] Optionally, the fixation base 2 and the elastic ring 1 are integrally structured, with the opening of the elastic ring 1 located on the side away from the fixation base 2. During use, the opening facilitates the patient's wearing of the device and further improves its breathability.

[0046] Optionally, the inner corners at both ends of the opening of the elastic ring 1 are rounded.

[0047] Optionally, protrusion 4 is made of a flexible material.

[0048] Optionally, there are two protrusions 4, which are respectively arranged on both sides of the elastic ring 1.

[0049] Optional, there are three protrusions (4), see attached document. Figure 4As shown, one protrusion 4 is located on one side of the fixed base 2, and the other two are arranged opposite to each other on both sides of the elastic ring 1.

[0050] When in use, the user wears the elastic ring 1 on their wrist through the opening. The airbag 3 and the protrusion 4 work together to provide pressure on the wrist, ensuring stability during use. Furthermore, the gaps between adjacent protrusions allow for heat dissipation and ventilation between the elastic ring 1 and the wrist. This prevents the wrist from being confined for extended periods, reducing allergic reactions and improving user comfort.

[0051] In one embodiment, an anti-allergy layer is adhered to the side of the protrusion 4 away from the elastic ring 1. The anti-allergy layer is not shown in the figure. For example, the anti-allergy layer can be a gel layer made of anti-allergy material. The gel layer is connected to the sidewall of the protrusion 4 by double-sided adhesive. The double-sided adhesive allows for easy replacement of the gel layer and facilitates the reuse of the fixation device.

[0052] Example 2

[0053] To facilitate use by patients with different wrist sizes and expand the applicability of the fixation device, based on Embodiment 1, this embodiment features an air inlet channel 13 on the elastic ring 1. The air inlet 31 of the airbag 3 is connected to one end of the air inlet channel 13, and the other end of the air inlet channel 13 is provided with a connector 14, which is connected to the airbag inflation device 5. The airbag 3 is inflated by the airbag inflation device 5. After the airbag 3 is inflated, it can be pushed to move inward towards the elastic ring 1. During use, the airbag 3 drives the protrusion 4 to move so that it fits against the user's wrist, ensuring stability during use. Moreover, it can be adaptively adjusted according to different wrist sizes, making it widely applicable and highly stable.

[0054] Example 3

[0055] Based on Embodiment 2, in this embodiment, the airbag inflation device 5 includes: a connecting pipe 51, an inflation ball 52, and an adjusting valve 53 disposed on the connecting pipe 51.

[0056] One end of the connecting tube 51 is detachably connected to the connector 14, and the connection method can be plug-in or threaded connection. The inflation ball 52 is connected to the other end of the connecting tube 51, and the regulating valve 53 is embedded in the connecting tube 51 for adjusting the air output. The inflation ball 52 has a one-way air inlet valve. In use, the inflation ball 52 is repeatedly pressed by hand. Outside air enters the inflation ball 52 through the one-way air inlet valve, and then enters the air bladder 3 through the connecting tube 51 after compression. As a result, the air bladder 3 begins to inflate and pushes the protrusion 4 to move inward toward the elastic ring 1, so that the protrusion 4 fits against the patient's wrist. It is convenient to use and can be adjusted to suit different users' wrist sizes. It is neither too tight nor too loose, ensuring stability while providing good comfort.

[0057] In one embodiment, the protrusion 4 may be a rubber block.

[0058] Example 4

[0059] like Figure 6 and Figure 7 As shown, in any of the above embodiments, in this embodiment, the protrusion 4 has a cavity 41 inside, which is connected to the cavity inside the airbag 3.

[0060] Optionally, the protrusion 4 and the airbag 3 are integrally structured, that is, in this embodiment, the protrusion 4 is made of the same elastic material as the airbag 3.

[0061] Any aspects not described in detail in this embodiment are techniques known in the art.

[0062] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
