Description

Technical Field

[0001] The invention relates to a supporting tube assembly of a Foley catheter. Background Art

[0002] Artificial urination is the process of draining urine to the outside by inserting a catheter through the urethra into the bladder. The Foley catheter is used in situations where the catheter needs to be maintained for a specified period of time. Artificial urination using the Foley catheter is widely used to drain urine or measure urine volume in critically ill patients, general surgery patients, urology surgery patients, or other patients with difficulty urinating.

[0003] However, the surgical procedure for inserting a Foley catheter into the bladder requires a cumbersome process in the preparation steps and the surgical steps. The hospital needs to prepare the Foley catheter kit in advance, and the Foley catheter kit needs to be sterilized, and includes three containers for inflation tubes and balloons, Kelly clamps, lubricating gel, saline for balloons, and disinfectant cotton. In the surgical preparation step, medical staff need to open the Foley catheter kit for surgery and separate the Foley catheter and balloon syringe from the wrapping paper, and lubricating gel, saline for balloons, and disinfectant cotton need to be placed in each container. In each process, special attention needs to be paid to prevent contamination, so there are cumbersome and time-consuming problems. At the hospital's operating level, this Foley catheter kit preparation process and surgical preparation process not only lead to increased costs, but also will cause labor waste of senior human resources and medical human resources. Therefore, it is necessary to develop instruments and methods that can further simplify and reduce the preparation process.

[0004] For this purpose, Korean Patent No. 10-1058241 “Assembly for inserting Foley catheter” is currently used.

[0005] Figure 1 1 is an illustration showing a state where the Foley catheter 10 is inserted into the bladder B through the Foley catheter assembly 20. The Foley catheter assembly 20 has the advantage of minimizing contamination and simplifying the surgical procedure of the operator before inserting the Foley catheter 10 into the bladder. However, the Foley catheter assembly 20 is used for inserting the Foley catheter 10 into the human body, and as a disposable item to be discarded after use, it has the disadvantage of high manufacturing cost.

[0006] That is, the existing Foley catheter assembly 20 is manufactured by injection molding or other methods using synthetic resin materials such as plastics, and therefore has a disadvantage of high manufacturing costs. As a result, hospitals using the Foley catheter assembly 20 have a problem of increased material procurement costs.

[0007] The Foley catheter 10 is arranged between the first roller 310 and the second roller 320. When the first roller 310 and the second roller 320 rotate, the Foley catheter moves forward by the friction between the roller and the Foley catheter. In this case, according to the driving principle of the Foley catheter assembly, the forward movement of the Foley catheter (i.e., the structure in which the rotational force of the first roller is transmitted to the second roller through the Foley catheter) is only realized by the rotation of the upper first roller. At this time, even if the forward movement of the Foley catheter is subject to a little resistance, the lower second roller will not rotate. Therefore, there is a problem that the Foley catheter itself cannot move forward. In addition, in terms of its characteristics, the Foley catheter 10 is made of a soft material with a specified elastic force. Therefore, if one side of the operating handle of the rotating roller is pressed, when the first roller rotates, the catheter will move forward to the left or right side of the non-center. Furthermore, when the Foley catheter is deflected to the maximum deflection position, friction between the Foley catheter and the housing will occur, causing the first roller to idle even if it is rotated. Since the friction required for forward movement cannot be fully provided, there is a disadvantage of being unable to move forward further.

[0031] According to one embodiment, a first syringe accommodating portion cutting line and a second syringe accommodating portion cutting line are also formed in the support tube assembly, which cross at least three surfaces different from the surface on which the open channel is formed, and syringe covering surfaces arranged in sequence can be formed on the side of the bonding surface arranged in parallel with the front surface.

[0032] According to one embodiment, the syringe housing portion is formed by folding the connecting portions of the three surfaces along the first syringe housing portion cutting line and the second syringe housing portion cutting line, and the syringe covering surface can surround the outer side of the syringe housing portion due to the folding.

[0038] Effects of the Invention

[0039] The present invention as described above has the following effects.

[0040] The invention can not only provide the same function as the existing Foley urinary catheter support tube, but also can be made of foldable material (paper, plastic or synthetic resin material), thus reducing the manufacturing cost.

[0041] The driving module is used to provide the driving force required to guide the Foley catheter, and can be made of a material with a specified rigidity. Since it is arranged on the folding support tube, the durability of the support tube assembly can be improved and the surgical accuracy can be improved.

[0042] Before use, the support tube assembly is provided to medical personnel in a state where the upper and lower parts are sealed by the bottom surface and the cover surface. The bottom surface and the cover surface can be removed and used immediately before performing surgery on the patient. Therefore, it is not only convenient to store and transfer, but also can maintain a sterile state for a long time.

[0043] Since the transfer roller that guides the Foley catheter into the bladder is applied with an anti-reversal structure, it is not only possible to prevent the Foley catheter from detaching from between the main roller and the sub-roller during storage, but also possible to prevent the Foley catheter inserted into the patient's body from being separated from the body during surgery.

[0044] Furthermore, since the Foley catheter is equipped with an anti-retrogression structure to prevent backward movement, it can not only prevent the Foley catheter from detaching from between the main roller and the sub-roller during storage, but also prevent the Foley catheter inserted into the patient's body from being separated from the body due to backward movement during surgery.

[0045] In addition, a medical supplies storage section is formed to store various medical supplies (syringes, sterile cotton, gel, distilled water, etc.) required for the surgical procedure of inserting a Foley catheter into the bladder. Therefore, medical personnel can easily complete the surgery without separately preparing the medical supplies required for the surgery.

[0046] Furthermore, the guide structure can guide the Foley catheter to be inserted vertically in males and horizontally in females, thereby ensuring the ease of surgery for medical personnel due to differences in reproductive structures between genders.

[0047] Furthermore, alignment grooves are formed on a plurality of rollers for providing a force for conveying the catheter, and the catheter receives force simultaneously through the rotation of the first roller and the second roller. When driven, the catheter obtains a force capable of overcoming the resistance applied to the catheter and being inserted into the body, and can move forward or backward without deviating to either side, thereby alleviating the patient's pain and ensuring the convenience of the operation.

[0048] In addition, the lower end of the Foley catheter is supported by the fourth part and the fifth part, and the upper end is pressed by the pressing component. Therefore, the Foley catheter can be inserted in an accurate position without being deflected in the front, back, left, and right directions.

[0049] Furthermore, since a clamp having a predetermined strength is provided on the foldable support tube, it is possible to prevent the problem that the shape of the foldable support tube is deformed due to the weight of the structure required for the catheter operation.

[0069] In many cases, in order to avoid obscuring the concept of the present invention, well-known structures and devices will be omitted, or a block diagram centering on the core functions of each structure and device may be shown.

[0070] In the full text of the specification, when it is indicated that a part "comprising or including" a certain structural element, unless there is a special record to the contrary, it also includes the meaning of other structural elements, but does not exclude other structural elements. In addition, the terms "......part", "......device", "module" and the like recorded in this specification refer to a unit for processing at least one function or work, which can be implemented by hardware or software or a combination of hardware and software. In addition, in the context of describing the present invention (especially, the context of the following claims), unless otherwise specified in this specification or clearly indicated as a different meaning based on the context, "a (a or an)", "one (one)", "the (the)" and similar related words can be used to include the meaning of the singular and the plural.

[0071] In the process of describing the embodiments of the present invention, when it is judged that the detailed description of the known functions or structures may unnecessarily confuse the subject matter of the present invention, the detailed description will be omitted. Moreover, the terms are defined in consideration of the functions in the embodiments of the present invention and may vary according to the intention or convention of the user or operator. Therefore, they should be defined based on the full content of this specification.

[0072] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0073] First, refer to Figures 2 to 6 The driving unit according to the embodiment of the present invention will be described in detail.

[0074] The driving unit of the embodiment of the present invention includes a first roller 310 and a second roller 320. The Foley catheter 10 is disposed between the first roller 310 and the second roller 320 and can move forward as the first roller 310 and the second roller 320 rotate due to the friction force generated between the rollers and the Foley catheter.

[0075] Figure 2 The driving part of the prior art is shown. Figure 2 The body 311 of the first roller and the body 321 of the second roller are cylindrical. Moreover, the Foley catheter 10 is disposed between the cylindrical bodies.

[0076] When inserting the Foley catheter, the medical staff can move the Foley catheter 10 forward by rotating the first roller or the second roller while holding it with one hand. The rotational force of the first roller or the second roller is transmitted to the Foley catheter 10, and the force to move the Foley catheter 10 is transmitted to the second roller or the first roller, so that the first roller and the second roller can rotate together. However, in the case of rotating the roller with one hand, it is inevitable that the force is biased to the left or right side, thereby, the Foley catheter 10 disposed between the rollers is biased to the left or right side to move forward. In addition, in the case where the Foley catheter 10 moves forward to the maximum biased position, even if the roller is rotated, the Foley catheter 10 cannot move forward further, resulting in the problem of roller idling.

[0077] In order to solve the above problems, Figures 3 to 6 The driving part of the embodiment of the present invention is shown.

[0078] and Figure 2 Similarly, a first roller 310 and a second roller 320 are provided, and the Foley catheter 10 is provided between the rollers. However, the difference is that: Figure 2 The roller body shown is cylindrical. Figures 3 to 6 The first roller body 311 or the second roller body 321 is formed with alignment grooves 311 a , 311 b , 321 a , 321 b .

[0079] A plurality of gear teeth are formed on the outer side surfaces of the first roller 310 and the second roller 320. The gear teeth of the first roller 310 and the gear teeth of the second roller 320 mesh with each other. Therefore, only one of the first roller 310 and the second roller 320 needs to be operated to rotate both rollers.

[0080] The alignment grooves 321a and 321b are in a concave shape and are disposed at the center of the body 311 and 321 of each roller 310 and 320. Specifically, the alignment grooves 321a and 321b are in a concave shape from the outer side surface of the first roller 310 or the second roller 320 toward a direction away from the Foley catheter 10. The shape includes Figures 3 to 6 The form shown is not particularly limited thereto. Figures 3 to 6 Although the state where the alignment grooves 321a and 321b are formed in the second roller is shown in the figure, the alignment grooves may also be formed in the first roller, and such an embodiment also belongs to the scope of the present invention.

[0081] On the other hand, preferably, the distance from the center of the first roller body 311 to the alignment groove and the distance d from the center of the second roller body 321 to the alignment grooves 311a and 311b correspond to the thickness (diameter) of the Foley catheter 10. Specifically, the distance d may be the same as the diameter of the Foley catheter 10, and preferably, the distance may be smaller than the diameter of the Foley catheter 10. Thus, even if the Foley catheter 10 is set in the alignment groove, as the contact area between the roller and the Foley catheter becomes wider, the friction force generated when the roller rotates can be stably transmitted to the Foley catheter 10. Thus, only a small amount of force is required to move the Foley catheter 10 forward and insert it into the body.

[0082] Furthermore, preferably, the width of the alignment grooves 321a, 321b corresponds to the thickness (diameter) of the Foley catheter 10. Specifically, the width may be the same as the diameter of the Foley catheter 10, and preferably, the width is greater than the diameter of the Foley catheter 10. This means that the greater the width, the wider the space of the Foley catheter 10 to the left or right becomes, and preferably, the width is a value greater than 1 times and less than 1.5 times the diameter of the Foley catheter 10.

[0083] On the other hand, the gear teeth of the roller body without the alignment grooves 321a and 321b can mesh with the gear teeth of other roller bodies. Thus, the Foley catheter 10 is set in the alignment grooves 321a and 321b as a closed space, and even if the roller is rotated, the Foley catheter 10 is only deflected in the closed space and can be roughly located at the center of the roller body to move forward. Thus, the pain of the patient can be minimized and the difficulty of the operation can be reduced.

[0084] Next, refer to Figures 7 to 9 The driving module 200 of the embodiment of the present invention is described in detail. The driving module 200 of the embodiment of the present invention is provided with the driving part, and the driving module 200 can be made of a low-cost and easy-to-form material with a specified strength, such as plastic, etc., but is not particularly limited thereto. That is, the driving module 200 performs the role of a support body for setting the driving part or for supporting the set driving part.

[0085] The driving module 200 provided with a driving unit in the embodiment of the present invention is arranged on the folding support tube 100 to provide the driving force required for inserting the catheter 12 of the Follett catheter 10 into the patient's genitals, specifically, providing the driving force for inserting the insertion head end 11 of the Follett catheter 10 into the bladder.

[0086] Reference Figure 7 The driving module 200 includes a first part 210, a second part 220, a third part 230 and a fourth part 240. Each part can be used as a whole to form the driving module 200. In another embodiment, the parts can also be separated and assembled to form the driving module 200.

[0087] The first portion 210 includes: a plurality of side surfaces 211, 212, formed with a pair of first roller insertion holes 214, 215 for setting the first roller 310; and a connecting surface 213, located between the plurality of side surfaces 211, 212. The pair of first roller insertion holes 214, 215 are recessed from the outermost edges of the plurality of side surfaces 211, 212 toward the inside (toward the connecting surface).

[0088] The first roller 310 may pass through a pair of first roller coupling holes 123 and 143 of the folding support tube 100 and a pair of first roller insertion holes 214 and 215 of the driving module 200 , which will be described later.

[0089] An insertion protrusion 271 is formed on one side 212 of the plurality of side surfaces 211 and 212, and is coupled to an insertion groove 272 formed on the other side 211. As the plurality of side surfaces 211 and 212 move toward each other, the insertion protrusion 271 is coupled to the insertion groove 272, and the folded state of the driving module 200 can be fixed. Fig.12 The driving module 200 whose folded state is fixed is inserted into the foldable support tube 100 to realize the assembly of the support tube assembly.

[0090] The second part 220 includes a plurality of side surfaces 221, 222, which are arranged on the connection surface 213 of the first part 210, and are formed with a pair of second roller insertion holes 223, 224 for arranging the second roller 320. The pair of second roller insertion holes 223, 224 may be in a form of being recessed from the outermost edges of the plurality of side surfaces 221, 222 toward the inner side (toward the connection surface). In another example, the second roller insertion holes 223, 224 may also be formed through the side surfaces 211, 212 of the first part 210.

[0091] The second roller 320 can pass through a pair of second roller combining holes 124, 144 of the folding support tube 100 and a pair of second roller insertion holes 223, 224 of the driving module 200 described later. In another example, it can also be placed in the second roller insertion holes 223, 224 of the second part 220.

[0092] The distance from the connection surface 213 to the first roller insertion holes 214 and 215 is greater than the distance from the connection surface 213 to the second roller insertion holes 223 and 224, and preferably, the difference corresponds to the thickness of the catheter 12. The catheter 12 is located between the first roller 310 and the second roller 320. As the first roller 310 (specifically, the operation of the operating handle) rotates together with the second roller 320, the catheter 12 moves forward or backward. The difference corresponds to the thickness of the catheter 12, so the rotational force of the first roller 310 and the second roller 320 can be stably transmitted to the catheter 12. Therefore, it has the advantage that only a small amount of force is required to insert the Foley catheter.

[0093] The third portion 230 may be provided in pair, one of the pair of third portions 230 being provided on the side surface 211 of the first portion 210 , and the other being provided on the other side surface 212 of the first portion 210 .

[0094] Hereinafter, a third portion 230 will be described by way of example.

[0095] The third portion 230 is formed with a pair of semi-guide holes 233 and 234 for guiding the urinary catheter 12 , and includes an upper surface 231 and a lower surface 232 in which the pair of semi-guide holes 233 and 234 are formed.

[0096] The upper surface 231 and the lower surface 232 are spaced apart from each other along the moving direction of the urinary catheter 12 , and the semi-guide holes 233 formed in the upper surface 231 and the semi-guide holes 234 formed in the lower surface 232 are aligned along the moving direction.

[0097] The pair of third parts 230 are disposed facing each other, and as the pair of third parts are connected to each other, the two half guide holes can together form a complete pair of guide holes. The urinary catheter 12 passes through the guide holes.

[0098] When inserting the Foley catheter, the subject lies down for the procedure. Male subjects need the catheter to be inserted vertically, while female subjects need the catheter to be inserted horizontally, depending on the anatomy of the male sex.

[0099] Therefore, when inserting the Foley catheter, in the case of a male, the Foley catheter needs to face downward so that the operator can hold the foldable support tube 100 and insert the catheter, and in the case of a female, the Foley catheter needs to face horizontally so that the operator can hold the foldable support tube 100 and insert the catheter.

[0100] Thus, the insertion angle of the urinary catheter can be adjusted by changing the positions of the semi-guide holes formed on the upper surface 231 of the third portion 230 and the semi-guide holes formed on the lower surface 232 .

[0101] Specifically, in one embodiment of the present invention, the semi-guide hole 233 formed on the upper surface 231 is formed at a position lower than the semi-guide hole 234 formed on the lower surface 232 (i.e., a position closer to the connection surface of the first portion). If the urinary catheter passes through the guide hole and faces downward, the Foley urinary catheter 10 can be easily inserted in a vertical direction naturally according to the angle of the operator's wrist when the support tube assembly is held by hand. In the case of performing surgery on a male subject, the effect is maximized.

[0102] Furthermore, in another embodiment of the present invention, the semi-guide hole 233 formed on the upper surface 231 is formed at a position higher than the semi-guide hole 234 formed on the lower surface 232 (i.e., a position farther from the connection surface of the first portion). If the urinary catheter passes through the guide hole and faces upward, when the support tube assembly is held by hand, the Foley urinary catheter 10 can be easily inserted in a horizontal direction naturally according to the angle of the operator's wrist. In the case of performing surgery on a female subject, the effect is maximized.

[0103] On the other hand, a pair of third parts 230 can be respectively arranged vertically on the multiple side surfaces 211, 212 of the first part 210, so that the directions in which the pair of main roller insertion holes 214, 215 of the first part face each other can be staggered with the directions in which the pair of guide holes of the third part face each other (specifically, perpendicular to each other). And, as the third parts are connected to each other, a gel receiving space 250 surrounded by the upper surface 231, the lower surface 232 of the third part 230 and the multiple side surfaces 211, 212 of the first part 210 can be formed. The gel receiving space 250 contains gel, and performs the function of applying gel (glue) to the catheter 12 passing through the gel receiving space 250. As the gel is applied to the catheter 12, the friction generated between each other can be minimized during the process of inserting the catheter 12 into the bladder, so that the catheter 12 can be easily inserted and the pain of the patient can be minimized.

[0104] Leakage prevention parts 235 and 236 are formed on a part of the contact surface of the third part 230 that contacts each other. The leakage prevention parts 235 and 236 are formed along the length direction of the contact surface, and a coupling part 237 is formed on one leakage prevention part 236 for coupling with another leakage prevention part 235. As an example, the coupling part 237 may be a hook with a groove formed at the center, and the coupling of the third part 230 can be achieved as the groove is coupled with another leakage prevention part 235. The sealing ability of the gel receiving space 250 is enhanced by the leakage prevention parts 235 and 236, and the gel contained in the gel receiving space 250 can be prevented from flowing out to the outside.

[0105] The fourth portion 240 is disposed inside the gel receiving space 250 and has a predetermined height. The fourth portion 240 is used to ensure the rigidity of the third portion 230. The connecting portion between the side surfaces 211 and 212 of the first portion 210 and the connecting surface 213 may be thinner than the thickness of other portions. The plurality of side surfaces 211 and 212 may be contacted with each other along the direction in which the third portion 230 approaches each other through the thinner portions to form the form of the driving module 200.

[0106] The fourth portion 240 is aligned with the third portion 230 along the width direction and is disposed inside the gel receiving space 250 formed by folding the plurality of side surfaces 211 and 212. Since the fourth portion 240 has a predetermined height, the third portion 230 can be provided with predetermined durability / rigidity.

[0107] And, if Figure 7 and Fig. 9 As shown, a guide groove 241 extending along the insertion direction of the urinary catheter 12 is formed on the upper surface of the fourth part 240. The urinary catheter 12 can be supported by the guide hole of the third part 230 and the guide groove 241 of the fourth part 240.

[0108] On the other hand, the upper surface of the fourth portion 240 may be formed to be inclined so that its height gradually decreases toward the guide groove 241. The fourth portion 240 is disposed inside the gel receiving space 250. As its height gradually decreases toward the guide groove 241, the upper surface of the fourth portion 240 may allow the gel inside the gel receiving space 250 to be gathered in the guide groove 241, and thus more gel may be applied to the urinary catheter passing through the guide groove 241.

[0109] Preferably, the guide groove 241 of the fourth portion 240 is formed to be aligned with the guide hole of the third portion 230 .

[0110] That is, in order to easily insert the urinary catheter into the male subject, in the embodiment where the guide hole of the third part 230 is lowered from the lower surface 232 toward the upper surface 231, preferably, the guide groove 241 of the fourth part 240 is also lowered from the lower surface 232 toward the upper surface 231 (refer to Fig. 9 (b) of the Regulations).

[0111] Furthermore, in order to easily insert a urinary catheter into a female subject, in the embodiment where the guide hole of the third portion 230 is raised from the lower surface 232 toward the upper surface 231, preferably, the guide groove 241 of the fourth portion 240 is also raised from the lower surface 232 toward the upper surface 231 (refer to Fig. 9 (c) of the Regulations).

[0112] On the other hand, Figure 7As shown, the fourth portion 240 is disposed at the front end of the first roller insertion holes 214, 215 and the second roller insertion holes 223, 224 for disposing the first roller 310 and the second roller 320, that is, disposed at a position closer to the patient than the rollers.

[0113] The driving module 200 of the embodiment of the present invention may further include a fifth portion 260 disposed at the rear ends of the first roller insertion holes 214 and 215 and the second roller insertion holes 223 and 224 , that is, disposed at a position farther from the patient than the rollers.

[0114] Similar to the fourth part 240, the fifth part 260 is formed with a groove 261 for guiding the Foley catheter 10, and the groove 261 of the fifth part 260 and the guide groove 241 of the fourth part 240 can be aligned in a row. Therefore, the front and rear of the Foley catheter 10 can be supported by the fourth part 240 and the fifth part 260 based on the roller, and the grooves for guiding the movement of the Foley catheter 10 are formed in the fourth part and the fifth part, so that the Foley catheter 10 can be easily inserted.

[0115] Furthermore, a pressing member 280 may be formed on one of the plurality of side surfaces 211 and 212. The pressing member 280 is formed to protrude at a position farther from the connection surface 213 than the semi-guide holes 233 and 234. With the Foley catheter 10 as a reference, the bottom is supported by the fourth portion 240 and the top is pressed by the pressing member 280, thereby preventing the Foley catheter 10 from being inserted toward an unexpected position.

[0116] Then, refer to Fig.10 The foldable support tube 100 for supporting a Foley urinary catheter according to an embodiment of the present invention is described in detail.

[0117] The folding support tube 100 for supporting the Follett catheter in the embodiment of the present invention can be made of foldable materials (e.g., paper, plastic, synthetic resin materials, etc.). Therefore, in addition to the advantage of low manufacturing cost, the Follett catheter can be easily removed after the operation is performed using the disposable Follett catheter.

[0118] like Fig.10 As shown, the foldable support tube 100 of the embodiment of the present invention is provided in the form of an unfolded view, and medical personnel can fold each structure according to the folding lines provided in the unfolded view, and can cut off part of the structure according to the cutting line to form the support tube assembly 1. In another embodiment, the foldable support tube 100 can also be provided to medical personnel in the form of a pre-folded packaged Foley catheter.

[0119] Reference Fig.10 , the folding support tube 100 is described in detail. Fig.10The unfolded view of the foldable support tube 100 shown can perform the function of a support tube for guiding the urinary catheter 12 of the Foley urinary catheter 10. The drive module 200 described later can be provided on the foldable support tube 100 to complete the manufacture of the support tube assembly 1.

[0120] The unfolded view of the foldable support tube 100 of the embodiment of the present invention includes a plurality of surfaces, including a front surface 110, a back surface 120, a first side surface 130, and a second side surface 140 that are adjacently arranged in parallel. The parallel arrangement means that the Foley catheter 10 is arranged along a cross direction when the Foley catheter 10 is arranged inside the foldable support tube 100, and the serial arrangement means that it is arranged along a parallel direction with the Foley catheter 10.

[0121] The front side 110, the back side 120, the first side 130 and the second side 140 can be folded by folding lines 111, 131 and 132 located at the connecting surfaces of each surface to form a quadrangular tube with a quadrangular cross section. Within the range of being able to form a quadrangular tube form, the arrangement order of the front side 110, the back side 120, the first side 130 and the second side 140 can be changed. In another embodiment, for example, a support tube with a circular cross section, a pentagonal cross section, a hexagonal cross section, or other polygonal tube forms can be formed.

[0122] exist Fig.10 In the figure, the solid line represented by a refers to the folding line, the dotted line represented by b refers to the interception line intercepted by the operator (medical personnel, etc.) before the operation, the solid line represented by c is the interception line intercepted after the insertion of the Foley catheter, and the area d represented by the oblique line refers to the bonding surface bonded to the other surface due to folding. Compared with other areas, the thickness of the folding line can be thinner, that is, compared with other areas, the folding line can be recessed to a specified depth, and when the user applies external force, the surfaces on both sides are folded together with the folding line as the center to maintain the folded state.

[0123] The front surface 110 , the back surface 120 , the first side surface 130 , and the second side surface 140 can be folded together to form the side surfaces of the support tube assembly 1 .

[0124] The foldable support tube 100 of the embodiment of the present invention may include a cover surface 141 and a bottom surface 142 .

[0125] The cover surface 141 and the bottom surface 142 respectively constitute the upper surface and the lower surface of the support tube assembly 1, and can be arranged in series with one of the front surface 110, the back surface 120, the first side surface 130 and the second side surface 140. For example, the cover surface 141 can be arranged in series with the front surface 110, and the bottom surface 142 can be arranged in series with the back surface 120, or they can be arranged in series with each other on the same surface. The front surface 110, the back surface 120, the first side surface 130 and the second side surface 140 can be folded with each other to form a polygonal column shape. Therefore, the upper surface and the lower surface of the support tube assembly 1 can be formed by the folding process by only arranging the cover surface 141 and the bottom surface 142 in series with one of the front surface 110, the back surface 120, the first side surface 130 and the second side surface 140.

[0126] A cover bonding surface 141 a is formed on one side of the cover surface 141 , and a bottom bonding surface 142 a is formed on one side of the bottom surface 142 . As the bonding surfaces are folded and bonded to other adjacent surfaces, a folded support tube 100 is formed.

[0127] The cover surface 141 and the bottom surface 142 together cover the upper and lower parts of the folding support tube 100 , and perform a barrier function to prevent external foreign matter from flowing into the inner side of the folding support tube 100 .

[0128] The folding support tube 100 can be provided to medical personnel in a packaged form with the cover surface 141 and the bottom surface 142 covered and the cutting lines not cut. When performing an operation, the cover surface 141 and the bottom surface 142 can be removed for use by cutting the open channel cutting line 112, the lower side cutting line 113, the gel insertion hole cover 116, etc.

[0129] A cutting line of the gel insertion hole cover 116 that is connected to the space inside the gel receiving space 250 is formed at a corresponding position between the upper end of the open channel and the cover surface 141 on one of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140. When the cutting line of the gel insertion hole cover is cut, an opening (gel insertion hole) of the gel receiving space 250 is formed at the cut portion, and a user can put gel into the gel receiving space 250 through the opening.

[0130] The first separation interception line 114 extends from the open channel interception line 112 to the gel insertion hole interception line, and the second separation interception line 115 extends from the gel insertion hole interception line to the connection portion connected to the cover surface 141. After the Foley catheter 10 is inserted into the bladder, when the Foley catheter 10 is separated from the folding support tube 100, it can be intercepted and used by the first separation interception line 114 and the second separation interception line 115.

[0131] A lower adhesive surface and an upper adhesive surface having a predetermined area may be provided at the upper end and the lower end of one of the front surface 110 , the back surface 120 , the first side surface 130 , and the second side surface 140 . Figure 2 FIG. 14 shows a state where the lower bonding surface 142a and the upper bonding surface 141a are respectively arranged at the lower end and the upper end of the second side surface 140. The lower bonding surface 142a and the upper bonding surface 141a are folded toward the second side surface 140, as shown in FIG. Fig.11 As shown, when the folding support tube 100 is assembled, it is bonded to the bottom surface 142 and the cover surface 141 to maintain the shape of the folding support tube 100. In addition, a side bonding surface 117 is provided at the end of the front surface 110, and when the folding support tube 100 is folded and assembled, it can be bonded to the back surface 120. However, this is only an example of forming a bonding surface, and the lower bonding surface and the upper bonding surface can also be provided on one of the four surfaces 110, 120, 130, 140 according to a specified area.

[0132] The folded support tube 100 formed by folding the front side 110 , the back side 120 , the first side 130 , and the second side 140 may be combined with a first roller 310 and a second roller 320 for transferring the urinary catheter 12 .

[0133] That is, the first roller 310 and the second roller 320 can be assembled to the folded support tube 100 (see Fig.11 ), can be followed Fig.13 Prepare as shown.

[0134] To this end, a pair of first roller connecting holes 123, 143 for inserting the first roller 310 can be formed on one of the front side 110, the back side 120, the first side surface 130 and the second side surface 140 and the surface facing thereto, and a pair of second roller connecting holes 124, 144 for inserting the second roller 320 can be formed at positions laterally (in the width direction) separated from the pair of first roller connecting holes 123, 143.

[0135] The position where the first roller coupling holes 123 , 143 and the second roller coupling holes 124 , 144 are formed through-through may be the lower part of the gel receiving space 250 .

[0136] like Fig.11 As shown, the first roller coupling holes 123 and 143 are coupled to the first roller 310. An elliptical pressing cutoff line 143a is formed in the first roller coupling hole 143. When the first roller 310 is assembled, if it is rotated to transfer the urinary catheter 12, the pressing cutoff line 143a is squeezed and broken by the rotation pressure of the first roller 310, and the urinary catheter 12 is appropriately squeezed, so that the urinary catheter 12 can be supported and smoothly inserted into the patient.

[0137] In this case, an anti-reverse structure may be provided in the first roller coupling holes 123 and 143 to prevent the first roller 310 from rotating in reverse.

[0138] Fig.15 This is an example diagram of an anti-reversal structure. Fig.15 As shown, in order to prevent reverse rotation, concavoconvex parts 125, 145 are formed on the inner circumference of the first roller coupling holes 123, 143, and are formed along the rotation direction of the first roller 310. The concavoconvex parts 125, 145 are in the form of guide surfaces 125a formed on the inner side surfaces of the first roller coupling holes 123, 143 with a predetermined length along the rotation direction of the first roller 310. In this case, a protrusion insertion groove 125b is provided between adjacent guide surfaces 125a, and is used to insert the anti-reversal protrusion 315 protruding from the outer circumference of the first roller 310 when the first roller 310 rotates in the reverse direction.

[0139] On the other hand, the concavoconvex portion 125, 145 includes: a first concavoconvex surface 125c, which is formed by bending from the inner circumferential surface of the first roller coupling hole along the circumferential direction and has a first curvature; and a second concavoconvex surface 125d, which is formed by bending from the inner circumferential surface along the circumferential direction and has a second curvature different from the first curvature, and is connected to the first concavoconvex surface at one point (refer to Fig.15 ).

[0140] The second roller 320 is inserted into the first roller coupling holes 124 and 144, and the urinary catheter 12 is located in the space between the first roller 310 and the second roller 320, with one side in contact with the first roller 310 and the other side in contact with the second roller 320. That is, when the first roller 310 rotates, the opposite side of the urinary catheter 12 in contact with the first roller 310 is supported by the second roller 320, and can move forward in conjunction with the rotation of the first roller 310.

[0141] As described above, the first roller 310 and the second roller 320 are independent of the folding support tube 100 , and can be assembled to the folding support tube 100 after the folding process of the folding support tube 100 is realized and the assembly of the driving module 200 is completed.

[0142] That is, Fig.11 As shown, in a state where the folding support tube 100 is folded, the first roller 310 and the second roller 320 may be combined with the first roller combining holes 123 and 143 and the second roller combining holes 124 and 144 .

[0143] The first roller 310 includes: a roller body 311 for guiding the transfer of the urinary catheter 12; and an operating handle 313, which is combined with the roller body 311 and is used for manual rotation by a user. The roller body 311 and the operating handle 313 are provided separately.

[0144] The roller body 311 has an outer diameter that can be inserted into the first roller coupling holes 123 and 143. The outer peripheral surface of the roller body 311 inserted into the first roller coupling holes 123 and 143 may be provided with an anti-reversal protrusion 315 protruding outward in the radial direction.

[0145] like Fig.15 As shown in part (a) of the figure, when the user rotates the operating handle 313 in the forward direction in the direction of inserting the urinary catheter 12 into the bladder, the anti-reversal protrusion 315 of the roller body 311 moves along the protrusion guide surface 125a of the concave-convex part 125. On the contrary, in the case of reverse rotation due to external force, that is, when the roller body 311 rotates in the reverse direction in the direction of the urinary catheter 12 away from the bladder, the anti-reversal protrusion 315 is inserted into the protrusion insertion groove 125b and is locked between adjacent concave-convex parts 125. In this way, reverse movement can be prevented and the urinary catheter 12 can be prevented from being separated from the bladder.

[0146] Corresponding to the diameter of the catheter 12, the first roller 310 and the second roller 320 can be configured separately. If the user rotates the operating handle 313 and turns the first roller 310, the second roller 320 coupled to the gear of the first roller 310 rotates inside the second roller coupling holes 124, 144, and the catheter 12 arranged between the first roller 310 and the second roller 320 can move forward or backward due to the friction with the rollers.

[0147] The driving module 200 can be inserted and arranged inside the folding support tube 100 with the cover surface 141 and the bottom surface 142 removed. Fig.12 and Fig.13 As shown, the first roller insertion holes 214, 215 of the driving module 200 are aligned with the first roller combining holes 123, 143 of the folding support tube 100, and the second roller insertion holes 223, 224 of the driving module 200 can be inserted to a position aligned with the second roller combining holes 124, 144 of the folding support tube 100.

[0148] If the assembly of the foldable support tube 100 and the driving module 200 is completed, gel is injected through the opening of the gel receiving space 250 , and the Foley catheter 10 can be inserted into the support tube assembly 1 to perform the operation.

[0149] As the folding support tube 100 is formed by folding or attaching the front surface 110, the back surface 120, the first side surface 130 and the second side surface 140, the cover surface 141 and the bottom surface 142 described above, the driving module 200, the first roller 310 and the second roller 320 can be combined with the folding support tube 100 to form a Fig.13 A support tube assembly of the form shown.

[0150] However, before actually being used in surgery, specifically, during the assembly process of the folding support tube 100 and the driving module 200 and the pre-insertion process of the Foley catheter, an opening for injecting gel into the gel receiving space and an opening for inserting the Foley catheter 10 into the folding support tube 100 are required. Therefore, the folding support tube 100 in the expanded view of the present invention is formed with an additional cutting line, and before use, a part of the structure can be cut off according to the cutting line to form the opening.

[0151] An open channel cutting line 112 may be formed on one of the front side 110, the back side 120, the first side 130 and the second side 140, and is formed from the bottom of the support tube along its length direction to a position spaced a specified distance from the bottom of the gel containing space 250 toward the bottom of the support tube.

[0152] That is, Fig.11 As shown in FIG. 1 , when the folded and unfolded diagram is shown, the open channel cutting line 113 is in an uncut state, and the open channel is maintained in an unopened state. If the medical staff cuts along the open channel cutting line 112 before use, Fig.12 As shown, the open channel is opened.

[0153] In this case, a lower cutoff line 113 is provided at the lower part of the open channel, and is inclined toward the two side surfaces of the surface forming the open channel cutoff line 112. With the inclined setting of the lower cutoff line 113, the lower end of the Foley catheter is exposed to the outside, which can make the connection with the urine bag simple. The lower cutoff line 113 is separated from the front side 110, the back side 120, the first side 130 and the second side 140 together with the open channel, as shown in FIG. Fig.13 As shown, a space capable of inserting the Foley catheter 10 is ensured by opening the lower portion.

[0154] Hereinafter, the use process of the support pipe assembly 1 according to the embodiment of the present invention having the above-described structure will be described with reference to the drawings.

[0155] like Fig.13 As shown, the support tube assembly 1 of the embodiment of the present invention includes a folded support tube 100 folded from an unfolded view, a driving module 200 and a first roller 310 and a second roller 320 combined therewith.

[0156] The folding support tube 100 can be waterproof coated on its surface. After the Foley catheter 10 is inserted into the folded state and the first roller 310 and the second roller 320 are combined with the first roller combining holes 123, 143 and the second roller combining holes 124, 144 and the first roller insertion holes 214, 215 and the second roller insertion holes 223, 224, it can be provided to medical personnel and the like through antibacterial sealed packaging.

[0157] In the manufacturing site of the folding support tube 100, the folding expansion diagram can be folded to manufacture the folding support tube 100. The staff can Fig.10 The folding lines of the unfolded view fold the front side 110 , the back side 120 , the first side surface 130 , and the second side surface 140 into a supporting tube shape of a quadrangular tube.

[0158] Moreover, if Fig.11 As shown, the folding support tube 100 in the shape of a square tube can be manufactured by bonding the bonding surfaces, and the driving module 200 is arranged inside the folding support tube 100. Thus, the manufactured support tube assembly 1 can be provided to medical personnel after sterilization packaging with the Foley urinary catheter 10 installed inside.

[0159] like Fig.12 As shown, when medical personnel insert the Foley catheter 10 into a patient, as the wrapping paper of the support tube assembly 1 is opened and the open channel cutting line 112 and the lower cutting line 113 of the folded support tube 100 are cut off, the lower part and the open channel of the folded support tube 100 are exposed to the outside.

[0160] Gel is poured into the inner space of the gel receiving space 250 through the opening of the gel receiving space 250 , and the Foley catheter 10 can be inserted from the lower part of the foldable support tube 100 along the upper direction.

[0161] like Fig.16 As shown, the catheter 12 and the branch tube 14 are inserted in sequence starting from the insertion head end 11 of the Foley catheter 10 by folding the open lower part of the support tube 10, and the medical staff rotates the operating handle 313 in the positive direction, so that the insertion head end 11 moves toward the upper side through the gel receiving space 250.

[0162] In this case, when the operating handle 313 is rotated forward, the main roller 310 rotates stably along the guide surfaces 125a, 145a inside the first roller coupling holes 123, 143. If the operating handle 313 is rotated reversely or the first roller 310 rotates reversely due to external force, the anti-reversal protrusion 315 is stuck in the insertion groove 125b to prevent reversal.

[0163] like Figure 6 As shown, as the urinary catheter 12 is transferred, if the insertion head 11 is inserted into the bladder, the first separation cutting line 114 and the second separation cutting line 115 are torn, opening a pair of third parts in the driving module 200 away from each other, so that the Foley urinary catheter 10 is separated from the support tube assembly 1.

[0164] Fig.17 This is an expanded view of a foldable support tube according to yet another embodiment of the present invention.

[0165] Below, omitted Fig.10The same parts of the folding support tube 100 of the embodiment are described together with the differences being emphasized.

[0166] exist Fig.17 In the embodiment of the present invention, a space is formed inside the folding support tube so that the syringe 400 can be accommodated inside the support tube assembly 1. For this purpose, a first syringe accommodating portion intercepting line 161 formed along the transverse direction (width direction) of the folding support tube 100 is formed on the remaining surfaces except the surface formed with the open channel intercepting line 112 among the front surface 110, the back surface 120, the first side surface 130 and the second side surface 140, and a second syringe accommodating portion intercepting line 164 is formed transversely at a portion separated from the first syringe accommodating portion intercepting line 161 by a predetermined distance along the length direction. As the first syringe accommodating portion intercepting line 161 and the second syringe accommodating portion intercepting line 164 are intercepted, the connecting portion between the first syringe accommodating portion intercepting line 161 and the second syringe accommodating portion intercepting line 164 is folded toward the inside of the folding support tube 100, so that a syringe insertion space N capable of accommodating the syringe 410 of the syringe 400 can be formed.

[0167] Furthermore, a first piston receiving section interception line 168 is formed laterally at a portion spaced a predetermined distance from the first syringe receiving section interception line 161 in the opposite direction toward the second syringe receiving section interception line 164, and a second piston receiving section interception line 162 is formed laterally at a portion spaced a predetermined distance from the first piston receiving section interception line 168 in the length direction. As the first piston receiving section interception line 168 and the second piston receiving section interception line 162 are intercepted, the connection portion between the first piston receiving section interception line 168 and the second piston receiving section interception line 162 is folded toward the inside of the folding support tube 100, thereby forming a piston insertion space M into which the piston 420 of the syringe 400 can be inserted.

[0168] Reference Fig.18 The syringe housing portion 160 is formed with a syringe insertion space N into which the syringe 410 of the syringe 400 can be inserted and a piston insertion space M into which the piston 420 can be inserted.

[0169] The syringe insertion space N refers to a space capable of accommodating the syringe 410 of the syringe 400. As the first syringe accommodating portion cutting line 161 and the second syringe accommodating portion cutting line 164 are cut off, the first syringe accommodating portion cutting line 161 and the second syringe accommodating portion cutting line 164 are cut off, and the connecting parts of the front 110, the back 120, the first side surface 130 and the second side surface 140 between the first syringe accommodating portion cutting line 161 and the second syringe accommodating portion cutting line 164 are folded toward the inside of the folding support tube 100.

[0170] The piston insertion space M refers to a space capable of accommodating the piston 420 of the syringe 400. As the first piston accommodating portion cutting line 168 and the second piston accommodating portion cutting line 162 are cut off, the connecting parts of the front 110, the back 120, the first side surface 130 and the second side surface 140 between the first piston accommodating portion cutting line 168 and the second piston accommodating portion cutting line 162 are folded toward the inside of the folding support tube 100.

[0171] The syringe flange insertion interception lines 163, 166 extend laterally along the outside from the syringe insertion space N or the piston insertion space M toward the connection part folded inside the folding support tube 100. As the syringe flange insertion interception lines 163, 166 are intercepted, a space in which the syringe flange 411 of the syringe 400 can be inserted is formed, so that the syringe 400 can be fixed in the syringe coupling part 160. Although the drawings show that the syringe flange insertion interception lines 163, 166 are formed in the syringe insertion space N, it is not limited thereto, and it should be understood that the syringe flange insertion interception lines can also be formed in the piston insertion space M.

[0172] The syringe 400 is combined with the fluid supply tube 14a, and the airbag 13 connected to the fluid supply tube 14a in a flowable manner is expanded by supplying a fluid such as distilled water. Preferably, the expansion process of the airbag 13 is performed after the insertion tip 11 is inserted into the bladder, and as the airbag 13 expands, the insertion tip 11 can be maintained in the bladder.

[0173] On the other hand, the foldable support tube of the embodiment of the present invention has the following difference at the structural level, that is, it also includes a medical supplies storage portion capable of storing medical supplies separately.

[0174] In one of the front side 110 , the back side 120 , the first side 130 and the second side 140 , a medical supply storage space forming surface 151 is provided at a lower position of the lower cutting line 113 , and an insertion groove 152 is formed on a surface facing the medical supply storage space forming surface 151 .

[0175] A cutting line is provided in a part of the medical supplies storage space forming surface 151. If the cutting is completed according to the cutting line, the medical supplies storage space forming surface 151 is used as a partition across the internal space of the folding support tube 100. As the cut portion of the medical supplies storage space forming surface 151 is inserted into the insertion groove 152, a medical supplies storage space is formed between the bottom of the folding support tube 100 and the medical supplies storage space forming surface 151. The medical supplies storage space can be used to store medical supplies such as sterile cotton, gel, distilled water, etc. required for the Foley catheter operation.

[0176] In the foldable support tube 100 of another embodiment of the present invention, an anti-backward structure is provided for preventing the Foley urinary catheter 100 from moving backward. Fig.10 and Fig.18 Detailed description.

[0177] The insertion head 11 of the Foley urinary catheter 10 is inserted into the bladder, and as the balloon 13 expands, the urinary catheter 12 can be fixed in the state of being inserted into the bladder, because the expanded diameter of the balloon 13 is larger than the diameter of the urethra, and the balloon 13 performs a stop function. Therefore, when the balloon 13 contracts due to the discharge of fluid in the balloon 13 to the outside, the Foley urinary catheter 10 may move backward.

[0178] In order to prevent this phenomenon, the present invention may additionally include an anti-backward structure, which is arranged in parallel with one of the front side 110, the back side 120, the first side 130 and the second side 140 (see Fig.10 ).

[0179] The anti-backward structure is similar to the formation principle of the medical supplies storage space.

[0180] In one of the front side 110 , the back side 120 , the first side 130 and the second side 140 , a back-recoil prevention portion forming surface 171 is provided above the lower cutting line 113 , and an insertion groove 172 is formed on a surface facing the back-recoil prevention portion forming surface 171 .

[0181] A cutting line is provided in a portion of the anti-retreat portion forming surface 171. If the cutting is completed according to the cutting line, as the cut portion of the anti-retreat portion forming surface 171 is inserted into the insertion groove 172, the anti-retreat portion forming surface 171 is used as a partition that crosses the internal space of the folding support tube 100.

[0182] As the anti-backward forming surface 171 crosses the inner space of the folding support tube 100 , the Foley catheter 10 can be prevented from moving backward.

[0183] Reference Fig. 20 , Fig. 20 The figure shows a state where the anti-recession forming surface 171 prevents the Follett catheter 10 from moving backward. The branch tube 14 is divided into a fluid injection tube 14a and a discharge tube 14b from one end of the catheter 12. In one example, the fluid injection tube 14a includes a portion extending from the branch portion at a specified inclination and a portion connected to the extending portion and extending parallel to the discharge tube 14b. As the anti-recession forming surface 171 crosses the inner space of the folding support tube 100, the tube (branch tube) branching from the Follett catheter 10 is stuck on the anti-recession forming surface 171, which can prevent the Follett catheter 10 from moving backward. After the operation, the anti-recession forming surface 171 is cut off, and the Follett catheter 10 can be easily separated from the inner side of the folding support tube 100.

[0184] Reference Fig.21 , the following describes a folding support tube according to another embodiment of the present invention.

[0185] exist Fig.21 The folding support tube is characterized in that i) an upper cutting line 117 for opening the upper part of the folding support tube is additionally formed, ii) a syringe receiving portion for receiving both the syringe barrel and the piston is formed, and syringe covering surfaces 181, 182, 183, 184 for covering the outer side of the syringe received in the syringe receiving portion are also formed, iii) support portion cutting lines 126, 127, 146, 147 for forming a support portion required for supporting the folding support tube after cutting are also provided, iv) an open channel exposing cutting line 118 for exposing a part of the open channel cutting line 112 for easily cutting the open channel cutting line 112 is also formed, and a cutting portion 119 is also formed.

[0186] The upper cutting line 117 is formed transversely along the width direction of the front surface 110, the back surface 120, the first side surface 130, the second side surface 140 and the attachment surface 150. When a part of the plurality of surfaces 110, 120, 130, 140, 150 is cut along the upper cutting line 117, the upper part of the folding support tube is opened. And, the driving module 200 is arranged through the opened upper part.

[0187] On the other hand, the upper cutting line 117 includes a portion 117a extending along the length direction of a portion of the plurality of faces 110, 120, 130, 140, 150. With the formation of the portion 117a extending along the length direction, the cutting of the upper cutting line 117 can be further facilitated.

[0188] On the other hand, in the remaining surfaces of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140 except the surface where the open channel cutting line 112 is formed, a first syringe receiving part cutting line 191 is formed along the width direction of the folding support tube 100, and a second syringe receiving part cutting line 192 is formed laterally at a portion separated from the first syringe receiving part cutting line 191 by a predetermined distance along the length direction. As the first syringe receiving part cutting line 191 and the second syringe receiving part cutting line 192 are cut, the connection portion between the first syringe receiving part cutting line 191 and the second syringe receiving part cutting line 192 is folded toward the inside of the folding support tube 100, so that a space capable of accommodating the syringe 400 can be formed.

[0189] Syringe flange insertion cutoff lines 193 and 194 into which the syringe flange of the syringe 410 can be inserted are formed between the first syringe housing section cutoff line 191 and the second syringe housing section cutoff line 192 .

[0190] On the other hand, Fig.21 The foldable support tube 100 is formed with syringe covering surfaces 181 , 182 , 183 , and 184 for covering the outer portion of the syringe housing portion after the syringe 400 is housed in the syringe housing portion.

[0191] The syringe cover surfaces 181, 182, 183, and 184 may be sequentially formed on the side of the attachment surface 150 along the width direction, and as the connection portions of the respective surfaces are folded, the syringe cover surface 184 is inserted into the syringe cover surface insertion space 185 and surrounds a portion of the outer side of the syringe receiving portion. Therefore, the syringe 400 inserted into the syringe receiving portion may be supported on the outer side by the syringe cover surfaces 181, 182, 183, and 184.

[0192] On the other hand, the support portion cutting lines 126, 127, 146, 147 are bent and formed, one side is connected to the side lower cutting line 113 and the upper cutting line 117, and the other side is connected to the connection folding line of the first side 130, the back side 120 and the second side 140. Therefore, after cutting the side lower cutting line 113 and the upper cutting line 117, the support portion cutting lines 126, 127, 146, 147 can form a support portion that can perform a bridge function of supporting the cut lower surface folding support tube 100. As a result, the support stability of the folding support tube 100 will be increased.

[0193] The open channel exposing cutting line 118 extends from the bonding surface 150 to the front surface 110 and the second side surface 140 along the width direction, and has a predetermined width to expose a portion (rear end portion) of the open channel cutting line 112 .

[0194] like Fig.21 As shown, the rear end of the open channel intercepting line 112 is located (i.e., exposed) in the space formed by the open channel exposing intercepting line 118. If the user applies force toward the upper end while holding a portion of the exposed open channel intercepting line 112, the open channel intercepting line 112 is intercepted from the front side 110. In order to ensure the ease of interception, a cut portion 119 in an oblique direction is formed inside the open channel intercepting line 112. Preferably, the oblique direction of the cut portion 119 is opposite to the intercepting direction. Therefore, a supporting force can be provided during the process of intercepting the open channel intercepting line 112.

[0195] On the other hand, referring to Fig. 22 and Fig.23 A foldable support tube according to another embodiment of the present invention is described.

[0196] Reference Fig. 22The clamp cutting line 149 may be formed through the back side 120, the first side 130 and the second side 140. The clamp cutting line 149 formed on the first side 130 is formed across the first side 130, and the clamp cutting line 149 formed on the back side 120 and the second side 140 may be formed toward the front end of the folding support tube along the approaching direction to be away from the clamp cutting line on the first side 130.

[0197] In addition, the clamp cutting line 159 of the embodiment of the present invention is also formed on the attachment surface 150, and its shape can be the same as the clamp cutting line 149 formed on the back side 120 or the second side surface 140. When the various surfaces are folded to form a folded support tube, it can partially overlap with the clamp cutting line 149.

[0198] After cutting the jig cutting lines 149, 159, the jig 500 is set on the cut portion. Fig.23 The clamp 500 includes a first body 510 and a second body 520. In one example, the clamp 500 may be made of synthetic resin such as plastic having a predetermined strength.

[0199] The rear ends of the first body 510 and the second body 520 are connected to each other, and the front ends may be separated by a predetermined interval. Such a separated portion is inserted into the cut portion of the jig cutting line 149, 159 and is set in the folding support tube.

[0200] A portion of the Foley catheter 10 can be exposed to the outside through the open channel of the folding support tube. At the rear end of the Foley catheter 10, the urine storage bag is combined with the syringe. The folding support tube made of paper material has the problem of shape deformation caused by the weight of the Foley catheter 10, the urine storage bag and the syringe. Therefore, the present invention needs to set a clamp 500 to prevent the open channel from unfolding, and it is necessary to support the weight of the Foley catheter 10, etc., so as to ensure the accuracy and simplicity of the operation.

[0201] The present invention as described above has the following effects.

[0202] The invention can not only provide the same function as the existing Foley urinary catheter support tube, but also can be made of foldable material (paper, plastic or synthetic resin material), thus reducing the manufacturing cost.

[0203] The driving module is used to provide the driving force required to guide the Foley catheter, and can be made of a material with a specified rigidity. Since it is arranged on the folding support tube, the durability of the support tube assembly can be improved and the surgical accuracy can be improved.

[0204] Before use, the support tube assembly is provided to medical personnel in a state where the upper and lower parts are sealed by the bottom surface and the cover surface. The bottom surface and the cover surface can be removed and used immediately before performing surgery on the patient. Therefore, it is not only convenient to store and transfer, but also can maintain a sterile state for a long time.

[0205] Since the transfer roller that guides the Foley catheter into the bladder is applied with an anti-reversal structure, it is not only possible to prevent the Foley catheter from detaching from between the main roller and the sub-roller during storage, but also possible to prevent the Foley catheter inserted into the patient's body from being separated from the body during surgery.

[0206] Furthermore, since the Follett catheter is equipped with an anti-retrogression structure to prevent backward movement, it can not only prevent the Follett catheter from detaching from between the main roller and the sub-roller during storage, but also prevent the Follett catheter inserted into the patient's body from being separated from the body due to backward movement during surgery.

[0207] In addition, a medical supplies storage section is formed to store various medical supplies (syringes, sterile cotton, gel, distilled water, etc.) required for the surgical procedure of inserting a Foley catheter into the bladder. Therefore, medical personnel can easily complete the surgery without separately preparing the medical supplies required for the surgery.

[0208] In addition, the lower end of the Foley catheter is supported by the fourth part and the fifth part, and the upper end is pressed by the pressing component. Therefore, the Foley catheter can be inserted in an accurate position without being deflected in the front, back, left, and right directions.

[0209] Furthermore, since a clamp having a predetermined strength is provided on the foldable support tube, it is possible to prevent the problem that the shape of the foldable support tube is deformed due to the weight of the structure required for the catheter operation.

[0210] In the above description, in order to enable ordinary technicians in the technical field to which the present invention belongs to easily understand and implement the present invention, although the embodiments shown in the accompanying drawings are described, this is only an example, and it should be understood that ordinary technicians in the technical field to which the present invention belongs can implement various modifications and other embodiments of equivalent technical solutions based on the embodiments of the present application. Therefore, the protection scope of the present application should be defined based on the protection scope of the invention claims.
