[0024] like Figure 1 As shown, the sheath includes a tube head 12, a puncture needle 11 and a pipeline 13. Figure 2 As shown, this embodiment provides a sheath fixing device for fixing the sheath to the patient's arm, and the device includes a supporting component and a tightening component.

[0025] Specifically, the state diagram of the support component when flattened is as follows Figure 4 As shown, the state diagram of the application is as follows Figure 3As shown, the support component includes two support bars 21 and a connecting belt 22. One end of the connecting belt 22 is fixedly connected to one of the support bars 21, and the other end of the connecting belt 22 passes through the other support bar 21. The area between the two support bars 21 is used to place the patient's arm. The connecting belt 22 can slide along the other support bar 21 to adjust the distance between the two support bars 21 to adapt to the arm sizes of more patients.

[0026] After the other support strip 21 slides to a suitable position, in order to prevent it from moving at will, the present embodiment adopts the following measures: a Velcro surface is provided on the bottom surface of the connecting belt 22, and a Velcro hook surface is provided on the other end of the connecting belt 22. The other end of the connecting belt 22 can be reversely attached to the Velcro surface, so that the other support strip 21 can be prevented from moving outward. The Velcro surface is provided on the bottom surface of the connecting belt 22, and the top surface of the connecting belt 22 is a smooth surface, which contacts the skin of the patient's arm. The purpose of this design is to improve the comfort of the connecting belt 22.

[0027] In order to further enhance the comfort of the connecting belt 22 and the supporting bar 21, the supporting bar 21 is a cylinder, and the connecting belt 22 is made of silicone or nylon, preferably silicone.

[0028] Specifically, Figure 2 As shown, the tightening component includes a limit block 31 and two straps 32. The bottom surface of the limit block 31 is provided with a groove matching the tube head 12. The limit block 31 is made of silicone, rubber or sponge. The limit block 31 is used to cover the tube head 12. One strap 32 corresponds to one support bar 21, and one end of the strap 32 is connected to the corresponding support bar 21. Here is a point. Figure 2 The vertical arrangement of the strap 32 shown in the figure does not mean that the strap 32 is made of a hard material. Figure 2 The state of the middle strap 32 is only for the convenience of those skilled in the art to understand the solution. In actual application, the strap 32 can be made of silicone or nylon. The two straps 32 are tightly connected by Velcro, so that the limit block 31 is fixed under the two straps 32, thereby fixing the tube head 12.

[0029] In order to further improve the stability of the fixing of the limit block 31 and take into account the comfort of the strap 32, this embodiment reasonably designs the positions of the Velcro fur surface and the hook surface on the strap 32. The specific measures are as follows: Figure 2 , Figure 5 As shown, one of the straps 32 has a Velcro surface on its bottom surface, and the bottom surface refers to the side facing the limit block 31. Figure 2 , Figure 6 , Figure 7As shown, the bottom surface of the other strap 32 is provided with a Velcro fleece surface, the top surface of the other strap 32 is provided with a Velcro hook surface, the top surface of the limiting block 31 is provided with a Velcro hook surface, and the top surface of the limiting block 31 is tightly connected to the bottom surface of the other strap 32.

[0030] When in use, the stopper 31 covers the pipe head 12, and then the other strap 32 is first attached to the stopper 31, and then one of the straps 32 is attached to the other strap 32. Considering that the pipeline 13 may need to be avoided, an avoidance groove 321 is provided on one of the straps 32 in this embodiment, and the avoidance groove 321 divides the one of the straps 32 into two straps, and the avoidance groove 321 is used to avoid the pipeline 13.

[0031] To facilitate assembly, Figure 2 , Figure 3 , Figure 7 As shown, the tightening component also includes two U-shaped clips 33, each end of the U-shaped clip 33 is provided with a circular plate 34, the inner wall of the circular plate 34 is provided with an insert block 35, and the end of the support bar 21 is provided with a circular hole 211. One support bar 21 is equipped with a U-shaped clip 33, and the insert block 35 matches the circular hole 211. One end of the strap 32 is connected to the corresponding U-shaped clip 33. The U-shaped clip 33, the circular plate 34, the insert block 35, and the support bar 21 are all made of plastic.

[0032] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
