Description

Anti-kink device for the sap tube

[0001] The present invention relates to a device for preventing bending of a sap pipe.

[0002] The IV set is used to inject patients with intravenous fluids such as saline or glucose.

[0003] In general, an infusion set may have a fluid container in which the fluid is stored, a fluid tube through which the fluid transferred from the fluid container flows, a catheter inserted into a patient's blood vessel to administer the drug transferred from the fluid tube, and a flow controller that controls the flow rate of the fluid transferred from the fluid tube to the catheter.

[0004] When the needle of such a catheter is inserted into a blood vessel on the back of the patient's hand or foot, one end of the fluid tube connected to the needle of the catheter and the other end of the fluid tube connected to the fluid container face in opposite directions, so a bent portion may be formed between the one and the other ends of the fluid tube.

[0005] However, if the bending angle of the bending part of the IV tube is excessively large, a bend may occur in the IV tube, in which case the inside of the IV tube may become blocked, and as a result, the flow of the IV fluid flowing inside the IV tube may stop, causing problems such as the patient's blood flowing backward through the IV tube.

[0006] The present invention has been devised to solve the above-described problems, and the purpose of the present invention is to provide a bend prevention device for a fluid pipe, which can maintain the shape of the bend portion of the fluid pipe and prevent the bend portion of the fluid pipe from being bent by covering the bend portion of the fluid pipe.

[0007] In addition, another object of the present invention is to provide a device for preventing bending of a sap pipe, which has a simple structure, thus minimizing manufacturing costs and enabling mass production.

[0008] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] In addition, the reinforcing member may further include a first mounting groove formed on the inner surface of the first cover, into which the lower portion of the bent portion of the sap pipe is mounted; and a second mounting groove formed on the inner surface of the second cover, into which the upper portion of the bent portion of the sap pipe is mounted.

[0011] Additionally, the first settling groove and the second settling groove may have a semicircular cross-sectional shape.

[0012] In addition, the reinforcing portion further includes a first catheter mounting portion formed at the distal end of the first mounting groove, on which the lower portion of the catheter is mounted; and a second catheter mounting portion formed at the distal end of the second mounting groove, on which the upper portion of the catheter is mounted, and the first catheter mounting portion and the second catheter mounting portion may have an inner diameter and an outer diameter that increase as they move away from the center of the reinforcing portion.

[0013] In addition, the reinforcing member may further include a first rounded portion rounded at the end of the first cover; and a second rounded portion rounded at the end of the second cover.

[0014] Additionally, the reinforcement part can be formed by 3D printing.

[0015] In addition, the fastening portion may include a hinge portion that rotatably connects one side of the first cover and one side of the second cover; and a fixing portion that fixes or releases the other side of the first cover and the other side of the second cover.

[0016] Additionally, the fixing member may be a cable tie.

[0017] In addition, the fixing part may include a folding cap having a hook groove and provided so as to be foldable on the other side of the first cover; and a hook provided on the other side of the second cover and fixedly or released from being fixedly caught on the hook groove by folding the folding cap.

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0036] Figure 1 is a perspective view showing a state in which a bend prevention device of a sap tube according to one embodiment of the present invention is installed in a sap set.

[0037] As illustrated in FIG. 1, the bend prevention device of the fluid tube according to one embodiment of the present invention covers the bend portion of the fluid tube (12) of the fluid set (10), thereby maintaining the shape of the bend portion of the fluid tube (12) and preventing the bend portion of the fluid tube (12) from being bent. This will be described in detail.

[0038] In general, the IV set (10) may have a IV container (11) in which the IV is stored, a IV tube (12) through which the IV transferred from the IV container (11) flows, a catheter (13) inserted into the patient's skin to administer the drug transferred from the IV tube (12), and a flow controller (not shown) for controlling the flow rate of the IV transferred from the IV 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 the back of the foot, one side of the IV tube (12) connected to the needle (13a) of the catheter (13) and the other side of the IV tube (12) connected to the IV container (11) face in opposite directions, so that a bent portion may be formed between the one side and the other side of the IV tube (12).

[0039] 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). However, the bend prevention device of the fluid tube according to one embodiment of the present invention can play a role in preventing the occurrence of bending of the fluid tube (12) by covering 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).

[0040] Meanwhile, the catheter (13) can be connected to the fluid tube (12) through a hub (13b) to which the needle (13a) is fixed.

[0041] FIG. 2 is a perspective view showing a bend prevention device for a sap tube according to one embodiment of the present invention, and FIGS. 3 and 4 are exploded perspective views showing a bend prevention device for a sap tube according to one embodiment of the present invention.

[0042] As shown in FIGS. 2 to 4, the bend prevention device of a sap pipe according to one embodiment of the present invention may include a reinforcing member (100) and a fastening member (200).

[0043] The reinforcing member (100) is the basic body of the present invention and can serve to cover the bent portion of the liquid pipe (12) and maintain the shape of the bent portion of the liquid pipe (12).

[0044] For example, the reinforcing member (100) may be formed by 3D printing. The reinforcing member (100) may have a shape corresponding to the bending portion of the sap tube (12) by 3D printing.

[0045] For example, the material of the reinforcing member (100) may include dental resin. Here, the dental resin may be copolymer polypropylene, but the present invention is not limited thereto, and can also be applied to other materials used in dental resin.

[0046] The reinforcing member (100) may include a first cover (110), a second cover (120), a first fixing groove (130), and a second fixing groove (140).

[0047] The first cover (110) can cover the lower part of the bent portion of the sap pipe (12). For example, the first cover (110) can have a U-shape.

[0048] The second cover (120) can cover the upper part of the bent portion of the sap pipe (12). For example, the second cover (120) can have a U-shape.

[0049] The first settling groove (130) is formed by being sunken into the inner surface of the first cover (110), so that the lower portion of the bent portion of the liquid tube (12) can be settling therein. For example, the first settling groove (130) may have a semicircular cross-section. As another example, the first settling groove (130) may be formed by 3D printing, so that it has a shape corresponding to the lower portion of the bent portion of the liquid tube (12).

[0050] The second settling groove (140) is formed by being sunken into the inner surface of the second cover (120), so that the upper portion of the folded portion of the liquid tube (12) can be settling therein. For example, the second settling groove (140) may have a semicircular cross-section. As another example, the second settling groove (140) may be formed by 3D printing and have a shape corresponding to the upper portion of the folded portion of the liquid tube (12).

[0051] The fastening member (200) can serve to fasten or release the first cover (110) and the second cover (120).

[0052] The fastening portion (200) may include a hinge portion (210) and a fixing portion (220).

[0053] 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) can be a hinge that rotatably connects one side of the first cover (110) and one side of the second cover (120).

[0054] The fixing member (220) can fix or release the other side of the first cover (110) and the other side of the second cover (120). For example, a cable tie (221) can be used as the fixing member (220).

[0055] Hereinafter, the process of covering the sap pipe (12) with the bend prevention device of the sap pipe according to one embodiment of the present invention will be described.

[0056] First, in a state where the sap tube (12) is bent, the lower part of the bent portion of the sap tube (12) is seated in the first seating groove (130) formed in the first cover (110). (See FIGS. 3 and 4)

[0057] Next, the second cover (120) rotates in a direction approaching the first cover (110) through the hinge portion (210). As a result, the second cover (120) is placed on the upper portion of the folded portion of the first liquid tube (12) that is placed in the first fixing groove (130), and then the upper portion of the folded portion of the first liquid tube (12) is placed in the second fixing groove (140) formed in the second cover (120).

[0058] Thereafter, the fixing member (220) fastens the first cover (110) and the second cover (120). At this time, if the fixing member (220) is a cable tie (221), the cable tie (221) can wrap around a specific portion of the first cover (110) and a specific portion of the second cover (120), and then tighten the specific portion of the first cover (110) and a specific portion of the second cover (120). (See Fig. 2)

[0059] For the additional embodiments of the present invention below, a configuration different from that described in one embodiment of the present invention will be described.

[0060] Figures 5 and 6 are perspective views showing a bend prevention device for a sap tube according to another embodiment of the present invention.

[0061] As shown in FIGS. 5 and 6, the device for preventing bending of a sap tube according to another embodiment of the present invention may further include a reinforcing portion (100) including a first round portion (150), a second round portion (160), a first catheter mounting portion (170), and a second catheter mounting portion (180), unlike the first embodiment of the present invention.

[0062] The first round portion (150) may be rounded at the end of the first cover (110). This first round portion (150) may prevent the bending of the fluid tube (12) bent along the end of the first cover (110) by limiting the bending angle of the fluid tube (12) bent along the end of the first cover (110). For example, the first round portion (150) may have a curved shape along the circumference of the end of the first cover (110).

[0063] The second round portion (160) may be rounded at the end of the second cover (120). This second round portion (160) may prevent the bending of the fluid tube (12) bent along the end of the second cover (120) by limiting the bending angle of the fluid tube (12) bent along the end of the second cover (120). For example, the second round portion (160) may have a curved shape along the circumference of the end of the second cover (120).

[0064] The first catheter mounting portion (170) is formed at the distal end of the first mounting groove (130), so that the lower portion of the catheter (13) can be mounted thereon. The first catheter mounting portion (170) may have an inner diameter and an outer diameter that increase as it moves away from the center of the reinforcing portion (100).

[0065] The second catheter mounting portion (180) is formed at the distal end of the second mounting groove (140), so that the upper portion of the catheter (13) can be mounted thereon. The second catheter mounting portion (180) may have an inner diameter and an outer diameter that increase as it moves away from the center of the reinforcing portion (100).

[0066] In this embodiment, the bending of the sap tube (12) that is bent along the end of the first cover (110) or the end of the second cover (120) can be prevented by the first round portion (150) and the second round portion (160).

[0067] In addition, in this embodiment, since the catheter (13) of the infusion set (10) is mounted on the first catheter mounting portion (170) and the second catheter mounting portion (180), the phenomenon of the reinforcing portion (100) moving along the bending portion of the infusion tube (12) can be prevented.

[0068] FIG. 7 is a perspective view showing a bend prevention device for a sap tube according to another embodiment of the present invention, and FIG. 8 is an exploded perspective view showing a bend prevention device for a sap tube according to another embodiment of the present invention.

[0069] As illustrated in FIGS. 7 and 8, a bend prevention device for a sap pipe according to another embodiment of the present invention may further include a non-slip portion (300), unlike the first embodiment of the present invention. In addition, the fixing portion (220) may replace the cable tie (221) and include a fixing projection (222) and a fixing groove (223).

[0070] The non-slip portion (300) is provided in the second mounting groove (140) and can serve to prevent the bend portion of the liquid pipe (12) mounted in the second mounting groove (140) from slipping. Accordingly, in the present embodiment, the phenomenon of the reinforcing portion (100) moving along the bend portion of the liquid pipe (12) can be prevented by the non-slip portion (300).

[0071] For example, the non-slip portion (300) may be formed in a rough shape in the second fixing groove (140).

[0072] As another example, the non-slip portion (300) may be coated with a non-slip material in the second mounting groove (140). Here, the non-slip material may be a polyurethane material.

[0073] The fixing projection (222) may be formed protrudingly on the inner surface of the second cover (120), and the fixing groove (223) may be formed recessedly on the inner surface of the first cover (110). For example, the fixing projection (222) and the fixing groove (223) may have a cylindrical shape.

[0074] FIGS. 9 and 10 are perspective views showing an example of a fastening portion of a bend prevention device of a sap tube according to one embodiment of the present invention.

[0076] The hinge part (210`) includes an elastic material, so that it can be folded by rotation of one side of the first cover (110) and one side of the second cover (120).

[0077] The folding cap (224) may be foldably provided on the other side of the first cover (110) and may have a hook groove (225). For example, the folding cap (224) may have a plate shape, and the hook groove (225) may be formed in the center of the folding cap (224).

[0078] The hook (226) is provided on the other side of the second cover (120) and can be caught or released from the hook home (225) by folding the folding cap (224). For example, the hook (226) may have a hook shape.

[0079] FIGS. 11a to 11c are cross-sectional views showing another example of a fastening portion of a bend prevention device of a sap tube according to one embodiment of the present invention.

[0080] Referring to FIGS. 11a to 11c, in the fastening portion (200), the hinge portion (210`) may include an elastic material, and the fixing portion (220) may include a catch groove (227) and a catch protrusion (228). For reference, FIG. 11a illustrates a state in which the catch protrusion (228) is caught and fixed in the catch groove (227), FIG. 11b illustrates a state in which the catch protrusion (228) begins to be released from the catch groove (227), and FIG. 11c illustrates a state in which the catch protrusion (228) is released from the catch groove (227).

[0081] The catch groove (227) may be formed by being sunken into the other side of the first cover (110). For example, the catch groove (227) may have a step shape.

[0082] The hook (228) is formed to protrude on the other side of the second cover (120) and can be hooked or unhooked in the hook groove (227). For example, the hook (228) may have a hook shape.

[0083] For example, the catch groove (227) and the catch projection (228) may have corresponding shapes, for example, they may have a cross-sectional shape in the shape of a fishhook.

[0084] According to the present invention, the bend prevention device of the liquid pipe according to one embodiment of the present invention has the effect of covering the bend portion of the liquid pipe (12), thereby maintaining the shape of the bend portion of the liquid pipe (12) and preventing bending of the bend portion of the liquid pipe (12).

[0085] In addition, the bend prevention device of the sap tube according to one embodiment of the present invention has a simple structure, so that the manufacturing cost can be minimized and mass production is possible.

[0086] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
