[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The utility model provides a technical solution: a catheter anti-bending protection device, comprising a sleeve 2 arranged outside the catheter 1, the sleeve 2 is axially open, and the cross-section is arc-shaped, which can be directly sleeved on the outside of the catheter 1 to provide support for the catheter 1 and prevent the catheter 1 from twisting or bending.
[0020] The sleeve 2 includes a chimeric structure, which can be arranged on the outer wall of the sleeve 2, on the inner wall of the sleeve 2, or between the inner and outer walls of the sleeve 2.
[0021] The interlocking structure includes a plurality of support bars 3 , which are arranged on the axial inner wall of the sleeve 2 to strengthen the longitudinal support force of the sleeve 2 and prevent the catheter 1 from bending.
[0022] The cross-sectional shape of the support bar 3 is semicircular to ensure that the support bar 3 does not cause wear to the surface of the catheter 1 .
[0023] Embodiment 1:
[0024] The support strip 3 is made of a foam strip material with a thickness of 1 mm. While providing hardness support, it can also allow the sleeve 2 to deform to a certain extent according to actual use requirements.
[0025] like Figure 1 As shown, the two ends of the catheter 1 are fixed by butterfly buckle stickers 4. When the catheter 1 needs to be bent into a C shape or an S shape, the butterfly buckle stickers 4 can also be used to fix the deformed position of the catheter 1.
[0026] like Figure 2 As shown, the butterfly buckle patch 4 includes a patch 41, on which an adhesive surface 42 is fixed, and on which a first flange end 43 and a second flange end 44 are attached. The catheter 1 is wrapped by the first flange end 43 and the second flange end 44. The back of the patch 41 has adhesive, and can be attached to the patient's skin or other places where the catheter needs to be fixed.
[0027] In addition, a long strip of Velcro can be used to fix the catheter 1 in a C-shape or S-shape in cooperation with the sleeve 2. Under normal circumstances, the two ends of the long strip of Velcro are adhered to the adhesive surface 42 of the butterfly card buckle 4, and can be removed and used independently when in use.
[0028] Embodiment 2:
[0029] like Figure 3-5 As shown, the opening of the sleeve 2 is connected by multiple connecting buckles 5, and the connecting buckle 5 is divided into a first end buckle 51 and a second end buckle 52. The first end buckle 51 includes a clamping head bottom 512 and a clamping head top 513. The clamping head bottom 512 is flat, and first buckles 514 are provided on the outer sides of both ends of the clamping head bottom 512. The clamping head top 513 is bent, and second buckles 515 are provided on the inner sides of both ends of the clamping head top 513. The first buckle 514 and the second buckle 515 can be buckled together to realize the buckling of the clamping head bottom 512 and the clamping head top 513. A cavity is formed between the clamping head bottom 512 and the clamping head top 513 for the second end buckle 52 to pass through, and a fixing pin 516 is provided on the clamping head bottom 513.
[0030] The second end buckle 52 includes a connecting arm 521 , and a plurality of through holes 522 are evenly distributed on the connecting arm 521 .
[0031] The bottom 512 of the clamp head and the top 513 of the clamp head can be loosened. After the second end buckle 52 passes through the cavity between the bottom 512 of the clamp head and the top 513 of the clamp head, the fixing needle 516 is inserted into the through hole 522 at a suitable position according to the diameter of the catheter 1. Finally, the bottom 512 of the clamp head and the top 513 of the clamp head are pinched to engage the first buckle 514 with the second buckle 515, so that the first end buckle 51 clamps the connecting arm 521, thereby fixing the sleeve 2, and the installation is convenient and quick.
[0032] Embodiment three:
[0033] like Figure 6 As shown, in this embodiment, the support bars 3 are evenly distributed in parallel on the axial inner wall of the sleeve 2.
[0034] Embodiment 4:
[0035] like Figure 7 As shown, in this embodiment, the support bars 3 are distributed in a broken line shape on the axial inner wall of the sleeve 2 .
[0036] 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.
