[0030] FIG. 1 is a perspective view showing a state in which a kinking prevention device for a fluid tube according to one embodiment of the present invention is installed in a fluid set.

[0031] As illustrated in FIG. 1, a bending prevention device for a fluid tube according to one embodiment of the present invention can cover a bent portion of a fluid tube (12) of a fluid set (10) to maintain the shape of the bent portion of the fluid tube (12) and prevent bending of the bent portion of the fluid tube (12). This will be explained in detail.

[0032] Generally, an intravenous fluid set (10) may have an intravenous fluid container (11) in which fluid is stored, an intravenous fluid tube (12) through which fluid transferred from the intravenous fluid container (11) flows, a catheter (13) inserted into the patient's skin to administer medication transferred from the intravenous fluid tube (12), and a flow regulator (not shown) for controlling the flow rate of fluid transferred from the intravenous fluid tube (12) to the catheter (13). When the needle (13a) of the catheter (13) is inserted into the back of the patient's hand or foot, one side of the intravenous fluid tube (12) connected to the needle (13a) of the catheter (13) and the other side of the intravenous fluid tube (12) connected to the intravenous fluid container (11) are oriented in opposite directions, so a bent portion may be formed between one side and the other side of the intravenous fluid tube (12).

[0033] At this time, if the bending angle of the bending portion of the fluid tube (12) is excessively large, a bend occurs in the fluid tube (12). The device for preventing bending of the fluid tube according to one embodiment of the present invention covers the bending portion of the fluid tube (12) of the fluid set (10), thereby maintaining the shape and bending angle of the bending portion of the fluid tube (12) and preventing the occurrence of bending of the fluid tube (12).

[0034] Meanwhile, the catheter (13) can be connected to the fluid tube (12) through a hub (13b) to which the needle (13a) is fixed.

[0035] FIG. 2 is a perspective view showing a kinking prevention device for a fluid tube according to one embodiment of the present invention, and FIG. 3 to 4 are exploded perspective views showing a kinking prevention device for a fluid tube according to one embodiment of the present invention.

[0037] The reinforcing part (100) serves as the basic body of the present invention and can cover the bent portion of the fluid tube (12) and maintain the shape of the bent portion of the fluid tube (12).

[0038] For example, the reinforcing part (100) can be formed by 3D printing. The reinforcing part (100) can have a shape corresponding to the bent portion of the fluid tube (12) by 3D printing.

[0039] For example, the material of the reinforcing part (100) may include dental resin. Here, the dental resin may be copolymer polypropylene, but the present invention is not limited thereto and may be applied to other materials used for dental resin.

[0040] The reinforcing member (100) may include a first cover (110), a second cover (120), a first seating groove (130), and a second seating groove (140).

[0041] The first cover (110) can cover the lower part of the bent portion of the fluid tube (12). For example, the first cover (110) may have a U-shape.

[0042] The second cover (120) can cover the upper part of the bent portion of the fluid tube (12). For example, the second cover (120) may have a U-shape.

[0043] The first seating groove (130) is formed by being recessed into the inner surface of the first cover (110) so that the lower part of the bent portion of the fluid tube (12) can be seated. For example, the first seating groove (130) may have a semicircular cross-sectional shape. For another example, the first seating groove (130) may be formed by 3D printing and may have a shape corresponding to the lower part of the bent portion of the fluid tube (12).

[0044] The second seating groove (140) is formed by being recessed into the inner surface of the second cover (120) so that the upper portion of the bent part of the fluid tube (12) can be seated. For example, the second seating groove (140) may have a semicircular cross-sectional shape. For another example, the second seating groove (140) may be formed by 3D printing and may have a shape corresponding to the upper portion of the bent part of the fluid tube (12).

[0045] The fastening part (200) can serve to fasten or unfasten the first cover (110) and the second cover (120).

[0046] The fastening part (200) may include a hinge part (210) and a fixing part (220).

[0047] The hinge portion (210) can rotatably connect one side of the first cover (110) and one side of the second cover (120). For example, the hinge portion (210) may be a hinge that rotatably connects one side of the first cover (110) and one side of the second cover (120).

[0048] The fixing part (220) can fix or release the other side of the first cover (110) and the other side of the second cover (120). For example, the fixing part (220) may use a cable tie (221).

[0049] Hereinafter, the process of covering the fluid tube (12) with a kinking prevention device for a fluid tube according to one embodiment of the present invention will be described.
