Description

Technical Field

[0001] The present invention relates to a Foley catheter support tube assembly. Background Art

[0002] Artificial urination is performed by inserting a urinary catheter into the bladder through the urethra to discharge urine to the outside, and a Foley catheter is used when the urinary catheter must be continuously retained for a certain period of time. Artificial urination using a Foley catheter is widely used for discharging urine or measuring urine output in severely ill patients, general surgery patients, urinary system surgery patients, and other patients with impaired urination.

[0003] However, when performing the procedure of indwelling a Foley catheter in the bladder, cumbersome procedures are required in the preparation and procedure steps. Hospitals need to prepare a Foley catheter set in advance, and the Foley catheter set requires sterile handling, and contains three containers for a drape, forceps, Kelly clamp, lubricating jelly, physiological saline for balloon, and sterilized cotton. In the procedure preparation step, medical staff need to open the Foley catheter set for the procedure, separate the Foley catheter and the syringe for balloon from the packaging, and place the lubricating jelly, physiological saline for balloon, and sterilized cotton into respective containers. Particular care must be taken to prevent contamination in each step, which is cumbersome and time-consuming. From the perspective of hospital management, such preparation of the Foley catheter set and the procedure preparation process leads to increased costs and waste of labor of high-level medical personnel. Accordingly, there is a demand for the development of instruments and methods that can simplify the preparation process.

[0004] For this purpose, "Assembly for inserting a Foley catheter" of Korean Registered Patent No. 10-1058241 is used.

[0005] Figure 1 is an illustrative diagram showing the Foley catheter 10 inserted into the bladder B through the Foley catheter assembly 20. The Foley catheter assembly 20 has the advantage of minimizing contamination before inserting the Foley catheter 10 into the bladder and simplifying the surgical procedure for the surgeon. However, the Foley catheter assembly 20 has the disadvantage of being a disposable type used for inserting the Foley catheter 10 into the human body and discarded after use, while having a high manufacturing cost.

[0006] In other words, conventional Foley catheter assemblies 20 have the disadvantage of high manufacturing costs because they are manufactured using synthetic resin materials such as plastic and by methods such as injection molding. Therefore, there is a problem in that hospitals using the Foley catheter assembly 20 will face increased material supply costs.

[0007] The Foley catheter 10 is positioned between the first roller 310 and the second roller 320, and moves forward due to the frictional force between the rollers and the Foley catheter when the first roller 310 and the second roller 320 rotate. In this case, due to the driving principle of the Foley catheter assembly, the Foley catheter moves forward only by the rotation of the upper first roller (i.e., a structure is adopted in which the rotational force of the first roller is transmitted to the second roller via the Foley catheter). However, in this case, even if there is some resistance to the advancement of the Foley catheter, the rotation does not occur up to the lower second roller, and there is a problem that the Foley catheter does not advance at all. Furthermore, due to its characteristics, the Foley catheter 10 is manufactured from a soft material with a predetermined elastic force, and as a result, when one side of the roller operating knob is pressed and turned, the catheter deviates to the left or right instead of the center when the first roller rotates, causing a problem. Furthermore, when the Foley catheter deflects to its maximum deflection position, rotating the first roller causes the Foley catheter to rub against the housing, resulting in the roller spinning freely without providing sufficient frictional force for further advancement, thus preventing it from moving any further.

[0008] [Patent Document 1] Korean Registered Patent No. 10-1058241 (2011.08.12) [Patent Document 2] Korean Published Patent No. 10-2022-0138265 (October 12, 2022) [Overview of the project] [Problems that the invention aims to solve]

[0009] The present invention aims to provide a foldable support tube that offers the same functionality as existing Foley catheter support tubes, but is manufactured from a flexible material (paper, vinyl, or synthetic resin), thereby reducing manufacturing costs. In particular, it aims to provide a Foley catheter support tube assembly that improves surgical accuracy by having a drive module that guides the Foley catheter with high strength.

[0010] Furthermore, the present invention aims to provide a drive unit in which alignment grooves are formed on the roller to prevent the deflection movement of a Foley catheter. [Means for solving the problem]

[0011] To solve the above-mentioned problems, one embodiment of the present invention provides a drive module for a Foley catheter support tube assembly, which is installed in a support tube for guiding a Foley catheter when the Foley catheter is inserted, and includes a first part including a side surface having a pair of first roller insertion holes in which a first roller is installed, and a connecting surface between these side surfaces; a second part disposed on the connecting surface of the first part, which is aligned with the pair of first roller insertion holes, and having a pair of second roller insertion holes in which a second roller is installed; a third part disposed on the side surface of the first part, which is each having a pair of half-guide holes for guiding the Foley catheter; and a fourth part disposed on the connecting surface of the first part so as to be located inside the space formed by the third part.

[0012] In one embodiment, the distance from the connecting surface of the first part to the first roller insertion hole may be longer than the distance from the connecting surface of the first part to the second roller insertion hole.

[0013] In one embodiment, the difference between the distance from the connecting surface of the first part to the first roller insertion hole and the distance from the connecting surface of the first part to the second roller insertion hole may correspond to the thickness of the Foley catheter.

[0014] In one embodiment, the third part may include an upper surface on which one of the pair of half-guide holes is formed, and a lower surface separated from the upper surface on which the other half-guide hole is formed.

[0015] In one embodiment, the direction in which the pair of first roller insertion holes of the first part face each other and the direction in which the pair of half guide holes of the third part face each other may be offset from each other.

[0016] In one embodiment, when the connection between the side surface and the connecting surface of the first part is bent in a direction that brings the third part closer to each other, a jelly-containing space surrounded by the top surface, bottom surface and the side surface of the first part may be formed.

[0017] In one embodiment, a leakage preventing portion may be formed along the longitudinal direction of the contact surface on the contact surface where the third portions formed on both side surfaces of the first portion contact each other.

[0018] In one embodiment, at least one of the leakage preventing portions may be formed with a coupling portion for coupling with another leakage preventing portion.

[0019] In one embodiment, the fourth portion may have a predetermined height and be disposed inside the jelly accommodating space.

[0020] In one embodiment, a guide groove extending in a direction aligned with the insertion direction of the Foley catheter may be further formed in the fourth portion.

[0021] In one embodiment, the half guide hole formed on the upper surface may be disposed closer to the connecting surface of the first portion than the half guide hole formed on the lower surface.

[0022] In one embodiment, the half guide hole formed on the lower surface may be disposed closer to the connecting surface of the first portion than the half guide hole formed on the upper surface.

[0023] In one embodiment, gear teeth may be formed on outer surfaces of the first roller and the second roller, and an alignment groove may be formed on the outer surface of the first roller or the second roller.

[0024] In one embodiment, the alignment groove may include a portion recessed from the outer surface of the first roller or the second roller in a direction away from the Foley catheter.

[0025] In one embodiment, a distance from the first roller or the second roller to the alignment groove may correspond to a thickness of the Foley catheter.

[0026] In one embodiment, the Foley catheter may be manufactured from a soft material.

[0027] The present invention also provides a Foley catheter support tube assembly on which the aforementioned drive module is installed, the Foley catheter support tube assembly comprising a front face, a back face, a first side face and a second side face, wherein an open passage through which a fluid supply tube of the Foley catheter passes is formed on any one of the front face, the back face, the first side face and the second side face, and a pair of first roller coupling holes aligned with the pair of first roller insertion holes of the first part are formed on both side faces of the face where the open passage is formed.

[0028] In one embodiment, first and second syringe receiving portion cut lines crossing the face formed with the open passage and at least three other faces may be further formed, and a syringe cover face may be formed to be sequentially arranged in parallel on a side portion of an adhesive face arranged in parallel with the front face.

[0029] In one embodiment, the syringe receiving portion is formed by cutting along the first and second syringe receiving portion cut lines and bending the connecting portions of the three faces, and the syringe cover face may be bent to surround the outside of the syringe receiving portion.

[0030] In one embodiment, an upper cut line and a side lower cut line crossing the front face, the back face, the first side face and the second side face may be further formed, and on both side faces connected to a face opposite to the face formed with the open passage, a bent first support portion cut line with one side connected to the upper cut line and the other side connected to a connecting portion between the opposite face and the both side faces, and a bent second support portion cut line with one side connected to the side lower cut line and the other side connected to the connecting portion between the opposite face and the both side faces may be formed.

[0031] In one embodiment, when the upper cut line, the side lower cut line, the first support portion cut line and the second support portion cut line are cut, a support portion for supporting the support tube assembly may be formed.

[0032] In one embodiment, an open path cut line that forms the open path when cut is formed on one of the front, back, first side, and second side surfaces, and an open path exposure cut line that exposes a portion of the open path cut line may be further formed on one of the surfaces.

[0033] In one embodiment, an incision is formed in the diagonal direction inside the open path cut line, and the diagonal direction may be inclined in the direction opposite to the direction in which the open path cut line is cut.

[0034] In one embodiment, clip cutting lines may be formed on three surfaces other than the surface on which the open path cutting line is formed, so that clips can be installed on each of them. [Effects of the Invention]

[0035] The present invention, as described above, has the following effects.

[0036] While providing the same functionality as existing Foley catheter support tubes, it can be manufactured from a flexible material (paper, vinyl, or synthetic resin), thus reducing manufacturing costs.

[0037] The drive module, which provides the driving force to guide the Foley catheter, is manufactured from a material with a predetermined rigidity and installed in the folding support tube, thereby improving the durability of the support tube assembly and the accuracy of the surgery.

[0038] The support tube assembly is provided to the medical team with its top and bottom closed by the bottom and lid before use, and the bottom and lid are removed immediately before application to the patient. This facilitates storage and transport, and allows for long-term maintenance of sterility.

[0039] By incorporating a reverse rotation prevention structure for the transfer roller that guides the Foley catheter into the bladder, the Foley catheter is prevented from detaching from the main roller and sub-roller during storage, and the problem of the Foley catheter separating from the patient's body after being inserted during surgery is resolved.

[0040] Furthermore, by incorporating a backward movement prevention mechanism to prevent the Foley catheter from moving backward, the problem of the Foley catheter detaching from the main roller and sub-roller during storage is solved, and the problem of the Foley catheter retracting and separating from the patient's body during surgery is resolved.

[0041] Furthermore, it has the advantage of providing a medical supplies compartment where various medical supplies (such as syringes, antiseptic swabs, gel, and distilled water) required during the surgical procedure of inserting a Foley catheter into the bladder can be stored, allowing the medical team to perform the surgery easily without having to prepare other medical supplies needed for the procedure.

[0042] Furthermore, the device is designed to guide the Foley catheter vertically for males and horizontally for females, which has the advantage of ensuring ease of surgery for medical staff in accordance with the differences in reproductive structure between sexes.

[0043] Furthermore, alignment grooves are formed in the rollers that provide the force to move the urinary catheter, and force is transmitted to the urinary catheter simultaneously by the rotation of the first and second rollers. This ensures that the urinary catheter has enough force to withstand the resistance applied to it during operation and be inserted into the body. Because it can move forward and backward without being biased to one side, it has the advantage of reducing the patient's pain and ensuring the convenience of the surgery.

[0044] Furthermore, the lower end of the Foley catheter is supported by the fourth and fifth parts, and the upper end is pressed by a retaining member, so that the Foley catheter can be inserted into a fixed position without being deflected in any direction.

[0045] Furthermore, by installing a clip with a predetermined strength on the folding support tube, it is possible to prevent the folding support tube from deforming due to the weight of the components required for urinary catheterization surgery. [Brief explanation of the drawing]

[0047] In some cases, known structures and devices may be omitted or shown in the form of block diagrams focusing on the central functions of each structure and device, in order to avoid ambiguity of the concept of the present invention.

[0048] Throughout the specification, where a part "comprising or including" a component, this means, unless otherwise specified, that it may include other components rather than excluding them. Furthermore, terms such as "...part," "...device," and "module" used in the specification mean a unit that processes at least one function or operation, which may be embodied as hardware, software, or a combination of hardware and software. Also, "a or an," "one," "the," and similar related terms may be used in the context describing the invention (particularly in the context of the following claims) to include both singular and plural unless otherwise specifically referred to herein or clearly refuted by the context.

[0049] When describing embodiments of the present invention, if a detailed explanation of a known function or configuration is deemed to obscure the gist of the invention, such detailed explanation will be omitted. Furthermore, the terms described later are defined in consideration of the functions in embodiments of the present invention, and they may be modified according to the intent or conventions of the user or operator. Therefore, their definitions should be based on the content throughout this specification.

[0050] The present application will be described in detail below with reference to the attached drawings.

[0051] First, with reference to Figures 2 to 6, the drive unit according to an embodiment of the present invention will be specifically described.

[0052] An embodiment of the present invention includes a drive unit comprising a first roller 310 and a second roller 320, wherein the Foley catheter 10 is positioned between the first roller 310 and the second roller 320 and can move forward by the frictional force generated between the rollers and the Foley catheter due to the rotation of the first roller 310 and the second roller 320.

[0053] Figure 2 shows a conventional drive unit. Referring to Figure 2, the body 311 of the first roller and the body 321 of the second roller are provided in a cylindrical shape. The Foley catheter 10 is positioned between these cylindrical bodies.

[0054] During Foley catheter insertion surgery, the medical team advances the Foley catheter 10 by rotating the first or second roller while holding it with one hand. The rotational force of the first or second roller is transmitted to the Foley catheter 10, and the force of the Foley catheter 10's movement is transmitted to the second or first roller, causing both the first and second rollers to rotate. However, when rotating the rollers with one hand, the force is inevitably biased to the left or right, causing the Foley catheter 10, positioned between the two rollers, to also move forward with a deviation to the left or right. Furthermore, once the Foley catheter 10 has advanced to its maximum deviation position, the Foley catheter 10 cannot be advanced any further even if the rollers are rotated, resulting in the rollers spinning freely.

[0055] Figures 3 to 6 show an embodiment of the present invention that solves the above problems.

[0056] Similar to Figure 2, Figures 3 to 6 also feature a first roller 310 and a second roller 320, with a Foley catheter 10 positioned between the two rollers. However, while the roller body is cylindrical in Figure 2, all of Figures 3 to 6 differ in that alignment grooves 311a, 311b, 321a, and 321b are formed in either the first roller body 311 or the second roller body 321.

[0057] Multiple gear teeth are formed on the outer 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 and connect. Therefore, even if only one of the rollers, the first roller 310 or the second roller 320, is operated, both rollers will rotate completely.

[0058] The alignment grooves 321a and 321b are provided in a recessed form in the center of the bodies 311 and 321 of each roller 310 and 320. Specifically, the alignment grooves 321a and 321b are provided in a recessed form on the outer surface of the first roller 310 or the second roller 320, moving away from the Foley catheter 10. The form includes, but is not limited to, those shown in Figures 3 to 6. Figures 3 to 6 show the alignment grooves 321a and 321b formed on the second roller, but embodiments in which the alignment grooves are formed on the first roller are also included in the scope of the present invention.

[0059] On the other hand, 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 preferably 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. This ensures that even when the Foley catheter 10 is positioned in the alignment groove, the contact area between the roller and the Foley catheter is increased, and the frictional force due to the rotation of the roller is reliably transmitted to the Foley catheter 10. Therefore, the Foley catheter 10 can be advanced and inserted into the body with less force.

[0060] Furthermore, it is preferable that the width of the alignment grooves 321a and 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 larger than the diameter of the Foley catheter 10. A larger width means that there is more space for the Foley catheter 10 to deflect to the left or right, so it is preferable that the width is between 1 and 1.5 times the diameter of the Foley catheter 10.

[0061] On the other hand, the gear teeth of roller bodies that do not have alignment grooves 321a and 321b may mesh with the gear teeth of other roller bodies. As a result, the Foley catheter 10 is positioned in the closed spaces of alignment grooves 321a and 321b, and even when the roller rotates, the Foley catheter 10 is deflected only within the closed spaces, and can advance while generally positioned in the center of the roller body. This minimizes the patient's discomfort and reduces the difficulty of the surgery.

[0062] Next, with reference to Figures 7 to 9, a drive module 200 according to an embodiment of the present invention will be specifically described. The drive module 200 according to an embodiment of the present invention is equipped with the aforementioned drive unit, and the drive module 200 may be manufactured from an inexpensive material such as plastic, which has a certain strength and is easy to mold, but is not particularly limited thereto. That is, the drive module 200 is configured to house the drive unit and to serve as a support structure that supports the installed drive unit.

[0063] The drive module 200, on which the drive unit according to an embodiment of the present invention is installed, is mounted on a folding support tube 100, which will be described later, and provides driving force for inserting the urinary catheter 12 of the Foley catheter 10 into the patient's genitals, specifically the insertion tip 11 of the Foley catheter 10 into the bladder.

[0064] Referring to Figure 7, the drive module 200 includes a first part 210, a second part 220, a third part 230, and a fourth part 240. Each part can constitute the drive module 200 as a whole, but in other embodiments, the drive module 200 can also be constructed by assembling the parts in separate configurations.

[0065] The first part 210 includes side surfaces 211, 212 having a pair of first roller insertion holes 214, 215 in which the first roller 310 is installed, and a connecting surface 213 between the side surfaces 211, 212. The pair of first roller insertion holes 214, 215 may be provided in a form that is recessed inward (towards the connecting surface) from the outermost edges of the side surfaces 211, 212.

[0066] The first roller 310 is installed by passing through a pair of first roller coupling holes 123, 143 of the folding support tube 100 (described later) and a pair of first roller insertion holes 214, 215 of the drive module 200.

[0067] An insertion projection 271 is formed on one of the sides 211, 212, for coupling with an insertion groove 272 formed on the other side 211. When the insertion projection 271 coupling with the insertion groove 272 while the sides 211, 212 move toward each other, the folded form of the drive module 200 can be fixed. The drive module 200 in its fixed folded form can be inserted into the folding support tube 100 shown in Figure 12, thereby assembling the support tube assembly.

[0068] The second part 220 is positioned on the connecting surface 213 of the first part 210 and includes side surfaces 221, 222 in which a pair of second roller insertion holes 223, 224 are formed, in which the second roller 320 is installed. The pair of second roller insertion holes 223, 224 may be provided in a form that is recessed inward (toward from the connecting surface) from the outermost edge of the side surfaces 221, 222. In other examples, the second roller insertion holes 223, 224 may be formed through the side surfaces 211, 212 of the first part 210.

[0069] The second roller 320 may be installed by passing through a pair of second roller coupling holes 124, 144 of the folding support tube 100 (described later) and a pair of second roller insertion holes 223, 224 of the drive module 200, or in another example, it may be placed in the second roller insertion holes 223, 224 of the second part 220.

[0070] Here, it is preferable that the distance from the connecting surface 213 to the first roller insertion holes 214, 215 is longer than the distance from the connecting surface 213 to the second roller insertion holes 223, 224, and that the difference corresponds to the thickness of the urinary catheter 12. The urinary catheter 12 is located between the first roller 310 and the second roller 320, and moves forward and backward while rotating together with the second roller 320 by the operation of the first roller 310 (specifically, the operation of the operating knob), and the difference has a value that corresponds to the thickness of the urinary catheter 12, so that the rotational force of the first roller 310 and the second roller 320 can be reliably transmitted to the urinary catheter 12. Thus, the advantage that Foley catheter insertion surgery can be performed with less force is achieved.

[0071] The third part 230 may be provided in a pair, with one of the third part 230s positioned on one side 211 of the first part 210 and the other on the other side 212 of the first part 210.

[0072] The following explanation will use Part 3, Chapter 230 as an example.

[0073] The third part 230 has a pair of half-guide holes 233, 234 for guiding the urinary catheter 12, and includes an upper surface 231 and a lower surface 232 on which the pair of half-guide holes 233, 234 are formed.

[0074] The upper surface 231 and the lower surface 232 are spaced apart from each other along the direction of travel of the urinary catheter 12, and the half guide hole 233 formed in the upper surface 231 and the half guide hole 234 formed in the lower surface 232 are aligned along the direction of travel.

[0075] A pair of third parts 230 may be positioned facing each other and connected to each other so that two half-guide holes come together to form a complete pair of guide holes through which the urinary catheter 12 passes.

[0076] When inserting a Foley catheter, the patient lies down during the procedure. Due to the differences in human anatomy between sexes, the catheter must be inserted vertically for male patients and horizontally for female patients.

[0077] Therefore, during Foley catheter insertion surgery, for males, if the Foley catheter is directed downwards, the surgeon can easily bend the support tube 100 and grasp it to insert the catheter, and for females, if the Foley catheter is directed horizontally, the surgeon can easily bend the support tube 100 and grasp it to insert the catheter.

[0078] Therefore, the insertion angle of the catheter can be adjusted by changing the positions of the half-guide holes formed on the upper surface 231 and the lower surface 232 of the third part 230.

[0079] Specifically, in one embodiment of the present invention, the half-guide hole 233 formed on the upper surface 231 is positioned lower than the half-guide hole 234 formed on the lower surface 232 (i.e., closer to the connecting surface of the first part), so that the catheter moves downward as it passes through the guide hole. When the support tube assembly is grasped by hand, the Foley catheter 10 can be easily inserted vertically naturally depending on the angle of the surgeon's wrist. The effect is maximized when performing surgery on male subjects.

[0080] In another embodiment of the present invention, the half-guide hole 233 formed on the upper surface 231 is positioned higher than the half-guide hole 234 formed on the lower surface 232 (i.e., further away from the connecting surface of the first part), so that the catheter moves upward as it passes through the guide hole. When the support tube assembly is grasped by hand, the Foley catheter 10 can be easily inserted horizontally naturally depending on the angle of the surgeon's wrist. This effect is maximized when performing surgery on female patients.

[0081] On the other hand, the pair of third parts 230 may be positioned perpendicular to the sides 211, 212 of the first part 210, and therefore the direction in which the pair of main roller insertion holes 214, 215 of the first part face each other and the direction in which the pair of guide holes of the third part face each other may be offset from each other (specifically, perpendicular to each other). Furthermore, when the third parts are connected to each other, a gel-containing space 250 is formed surrounded by the upper surface 231 and lower surface 232 of the third part 230 and the sides 211, 212 of the first part 210. The gel-containing space 250 contains gel and serves to coat the urinary catheter 12 passing through the gel-containing space 250 with gel (jelly). By coating the urinary catheter 12 with gel, friction between the catheter and the urinary catheter 12 during insertion into the bladder is minimized, making insertion of the catheter 12 easier and minimizing discomfort for the patient.

[0082] Leak-proof portions 235 and 236 are formed on some of the contact surfaces where the third parts 230 come into contact with each other. The leak-proof portions 235 and 236 are formed along the longitudinal direction of the contact surfaces, and a coupling portion 237 is formed on one of the leak-proof portions 236 for coupling with the other leak-proof portion 235. The coupling portion 237 may be provided in the shape of a hook with a groove in the center, for example, and the third parts 230 can be coupled by coupling the other leak-proof portion 235 into the groove. The leak prevention sections 235 and 236 enhance the sealing ability of the gel containment space 250, preventing the gel contained in the gel containment space 250 from leaking to the outside.

[0083] The fourth part 240 is located inside the gel containment space 250 and has a predetermined height. The fourth part 240 is configured to ensure the rigidity of the third part 230. The connecting portion between the sides 211, 212 of the first part 210 and the connecting surface 213 may be thinner than the other parts. The thinner portion allows the sides 211, 212 of the third part 230 to bend toward each other, completing the form of the drive module 200.

[0084] The fourth part 240 is aligned with the third part 230 in the width direction and is positioned inside the gel containment space 250 formed by the folding of its sides 211 and 212 toward each other. Since the fourth part 240 has a predetermined height, it can provide the third part 230 with a predetermined durability / rigidity.

[0085] Furthermore, as shown in Figures 7 and 9, a guide groove 241 extending in the direction of insertion of the urinary catheter 12 is formed on the upper surface of the fourth part 240. The urinary catheter 12 may be supported by the guide hole of the third part 230 and the guide groove 241 of the fourth part 240.

[0086] On the other hand, the upper surface of the fourth part 240 may be formed inclined such that its height decreases towards the guide groove 241. The fourth part 240 is positioned inside the gel-retaining space 250. Because the upper surface of the fourth part 240 decreases in height towards the guide groove 241, the gel inside the gel-retaining space 250 can collect in the guide groove 241, and thus more gel can be applied to the urinary catheter 12 passing through the guide groove 241.

[0087] Preferably, the guide groove 241 of the fourth part 240 is formed to be aligned with the guide hole of the third part 230.

[0088] In other words, in embodiments where the guide hole of the third part 230 is lower from the lower surface 232 to the upper surface 231 to facilitate catheter insertion into male subjects, it is preferable that the guide groove 241 of the fourth part 240 is also formed to be lower from the lower surface 232 to the upper surface 231 (see Figure 9(b)).

[0089] Furthermore, in embodiments in which the guide hole of the third part 230 is raised from the lower surface 232 to the upper surface 231 to facilitate catheter insertion for female subjects, it is preferable that the guide groove 241 of the fourth part 240 is also formed to be raised from the lower surface 232 to the upper surface 231 (see Figure 9(c)).

[0090] On the other hand, as shown in Figure 7, the fourth part 240 is positioned further forward than the first roller insertion holes 214, 215 and the second roller insertion holes 223, 224 in which the first roller 310 and the second roller 320 are installed, that is, closer to the patient than the rollers.

[0091] The drive module 200 according to an embodiment of the present invention may further include a fifth part 260 positioned at a rear end of the first roller insertion holes 214, 215 and the second roller insertion holes 223, 224, i.e., further away from the patient than the rollers.

[0092] The fifth part 260, like the fourth part 240, has 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 may be aligned in a straight line with respect to each other. Thus, the Foley catheter 10 may be supported by the fourth part 240 and the fifth part 260 at the front and rear with respect to the roller, and grooves for guiding the movement of the Foley catheter 10 are formed in the fourth and fifth parts, making it easy to insert the Foley catheter 10.

[0093] Furthermore, a retaining member 280 may be formed on either side 211 or 212. The retaining member 280 is formed to protrude further from the connecting surface 213 than the half guide holes 233 and 234. With the Foley catheter 10 as the reference, the bottom is supported by the fourth part 240 and the top is held in place by the retaining member 280, preventing the Foley catheter 10 from being inserted towards an unintended position.

[0094] Next, with reference to Figure 10, a specific example of a foldable support tube 100 for supporting a Foley catheter according to an embodiment of the present invention will be described.

[0095] The foldable support tube 100 for supporting a Foley catheter according to an embodiment of the present invention is made of a bendable material (for example, paper, vinyl, synthetic resin, etc.), and therefore has the advantage of reducing manufacturing costs and allowing for easy and simple removal from the Foley catheter after insertion surgery for disposable Foley catheters.

[0096] In an embodiment of the present invention, the folding support tube 100 is provided in the form of an unfolded diagram, as shown in Figure 10. Medical personnel can fold each component along the folding lines in the unfolded diagram and cut out some components along the cutting lines to form the support tube assembly 1. In another embodiment, the folding support tube 100 may be packaged with the Foley catheter in a pre-folded state and provided to the medical personnel.

[0097] The folding support tube 100 will be described in detail with reference to Figure 10. The unfolded view of the folding support tube 100 shown in Figure 10 serves as a support tube that guides the urinary catheter 12 of the Foley catheter 10. The drive module 200, described later, may be installed in the folding support tube 100, and the support tube assembly 1 may be manufactured and completed.

[0098] The unfolded view of the folding support tube 100 according to an embodiment of the present invention includes multiple surfaces, but the front surfaces 110 are arranged in parallel adjacent to each other. 1st aspect 120, Back Including 130 and a second side surface 140. Here, parallel arrangement means that when the Foley catheter 10 is provided inside the folding support tube 100, the arrangement is in a direction that crosses the Foley catheter 10, and series arrangement means that the arrangement is in a direction that is parallel to the Foley catheter 10.

[0099] Front 110, 1st aspect 120, Back 130 and the second side surface 140 can be bent by the bending lines 111, 131, 132 located on the connecting surfaces of each surface to form a square tube with a square cross-section. Within the range in which the shape of a square tube can be formed, the front surface 110, 1st aspect 120, BackThe arrangement order of 130 and the second side surface 140 may be changed, and in other embodiments, support tubes of various polygonal shapes may be formed, such as circular tubes with a circular cross-section, pentagonal tubes with a pentagonal cross-section, and hexagonal tubes with a hexagonal cross-section.

[0100] In Figure 10, the solid line labeled a represents the fold line, the dotted line labeled b represents the cut line to be cut by the user (medical staff, etc.) before surgery, the solid line labeled c represents the cut line to be cut after insertion of the Foley catheter, and the hatched area d represents the adhesive surface that is folded and adhered to other surfaces. The fold line may be formed with a thinner thickness than other areas; that is, the fold line is formed by being indented to a certain depth compared to other areas, so that when the user applies external force, the surfaces on both sides of the fold line fold together and maintain the folded state.

[0101] Front 110, 1st aspect 120, Back 130 and the second side surface 140 are bent toward each other to form the side surface of the support pipe assembly 1.

[0102] The folding support tube 100 according to the embodiment of the present invention may include a lid surface 141 and a bottom surface 142.

[0103] The lid surface 141 and the bottom surface 142 form the top and bottom surfaces of the support pipe assembly 1, respectively, and the front surface 110, 1st aspect 120, Back 130 and either the second side surface 140 may be arranged in series with each other. For example, the lid surface 141 may be arranged in series with the front surface 110, and the bottom surface 142 may be 1st aspect It can be arranged in series with 120, and it is also possible to arrange them in series with each other on the same plane. Front 110, 1st aspect 120, Back Since 130 and the second side surface 140 are bent toward each other to form a polygonal prism, the lid surface 141 and the bottom surface 142 are the front surface 110, 1st aspect 120, BackEven if only one of the surfaces 130 and the second side surface 140 is arranged in series with the support tube assembly 1, the bending process will result in it forming the top and bottom surfaces of the support tube assembly 1.

[0104] A lid adhesive surface 141a is formed on one side of the lid surface 141, and a bottom adhesive surface 142a is formed on one side of the bottom surface 142. The adhesive surfaces are folded and adhered to the adjacent surfaces to form a folding support tube 100.

[0105] The lid surface 141 and the bottom surface 142 both cover the top and bottom of the folding support tube 100, and play a role in preventing external foreign matter from flowing into the inside of the folding support tube 100.

[0106] The folding support tube 100 may be packaged and provided to the medical team with its lid 141 and bottom 142 covered and the cut lines left uncut. When performing surgery, the open channel cut line 112, the lower side cut line 113, the gel insertion hole cover 116, etc. are cut off, and the lid 141 and bottom 142 are removed before use.

[0107] Front 110, 1st aspect 120, Back On either side 130 or the second side surface 140, a cut line is formed at the corresponding position between the upper end of the open passage and the lid surface 141, which, when cut, connects to the space inside the gel containment space 250. When the cut line of the gel containment space lid is cut, the opening (gel insertion hole) of the gel containment space 250 is located in the cut portion, and the user can put gel into the gel containment space 250 through the opening.

[0108] The first separation cut line 114 extends from the open channel cut line 112 to the gel insertion hole cut line, and the second separation cut line 115 extends from the gel insertion hole cut line to the connecting portion that connects to the lid surface 141. The first separation cut line 114 and the second separation cut line 115 are cut when the Foley catheter 10 is folded and separated from the support tube 100 after the Foley catheter 10 has been inserted into the bladder.

[0109] Front 110, 1st aspect 120, Back Lower and upper adhesive surfaces may be provided on the lower and upper ends of either the 130 or the second side surface 140, covering a certain area. Figure 10 shows how the lower adhesive surface 142a and upper adhesive surface 141a are provided on the lower and upper ends of the second side surface 140, respectively. When the second side surface 140 is folded and assembled as a folding support tube 100 as shown in Figure 11, the lower adhesive surface 142a and upper adhesive surface 141a are bonded to the bottom surface 142 and the lid surface 141, so as to maintain the shape of the folding support tube 100. In addition, a side adhesive surface 117 is provided on the edge of the front surface 110, and when it is folded and assembled as a folding support tube 100... 1st aspect It is possible to bond to surface 120. However, this is only one example of how a bonding surface can be formed, and there are many other possible embodiments in which a lower bonding surface and an upper bonding surface are provided over a certain area on any one of the four surfaces 110, 120, 130, and 140.

[0110] Front 110, 1st aspect 120, Back A first roller 310 and a second roller 320 for transporting the urinary catheter 12 may be attached to the folding support tube 100, which is formed by bending parts 130 and the second side surface 140.

[0111] In other words, the first roller 310 and the second roller 320 can be assembled onto the folded support tube 100 (see Figure 11), and the assembly can be prepared as shown in Figure 13.

[0112] For this reason, front 110, 1st aspect 120, Back A pair of first roller coupling holes 123, 143 into which the first roller 310 is inserted may be formed through either one of the surfaces 130 and the second side surface 140 and the surface opposite it, and a pair of second roller coupling holes 124, 144 into which the second roller 320 is inserted may be formed through at a position separated laterally (widthwise) from the pair of first roller coupling holes 123, 143.

[0113] The positions where the first roller coupling holes 123, 143 and the second roller coupling holes 124, 144 are formed through each other may be lower than the position where the gel containment space 250 is formed.

[0114] As shown in Figure 11, the first roller 310 is connected to the first roller connection holes 123 and 143. An elliptical press-cut line 143a is formed in the first roller connection hole 143. The press-cut line 143a is pressed and cut by the rotational pressure of the first roller 310 when the first roller 310 is assembled and rotated for the transport of the urinary catheter 12, thereby properly compressing the urinary catheter 12 and supporting its smooth insertion into the patient.

[0115] In this case, the first roller coupling holes 123 and 143 may be provided with a reverse rotation prevention structure configured to prevent the first roller 310 from rotating in the reverse direction.

[0116] Figure 15 is an illustrative diagram showing a reverse rotation prevention structure. As shown in Figure 15, in order to prevent reverse rotation, uneven surfaces 125 and 145 are formed on the inner circumferential surfaces of the first roller coupling holes 123 and 143 in the direction of rotation of the first roller 310. The uneven surfaces 125 and 145 are formed in the form of guide surfaces 125a that are formed on the inner surfaces of the first roller coupling holes 123 and 143 for a certain length along the direction of rotation of the first roller 310. At this time, between adjacent guide surfaces 125a, there are projection insertion grooves 125b into which a reverse rotation prevention projection 315, which is formed to protrude from the outer circumferential surface of the first roller 310, is inserted when the first roller 310 rotates in the reverse direction.

[0117] On the other hand, the uneven portions 125 and 145 include a first uneven surface 125c that curves with a first curvature along the circumferential direction from the inner circumferential surface of the first roller coupling hole, and a second uneven surface 125d that curves with a second curvature different from the first curvature along the circumferential direction from the inner circumferential surface, and is connected to the first uneven surface at one point (see Figure 15).

[0118] The second roller 320 is inserted into the second roller connecting holes 124 and 144, and the urinary catheter 12 is positioned 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 is rotated, the opposite side of the urinary catheter 12 that is in contact with the first roller 310 is supported by the second roller 320, and the catheter becomes able to move forward in conjunction with the rotation of the first roller 310.

[0119] As mentioned above, the first roller 310 and the second roller 320 are provided separately from the folding support tube 100 and may be assembled to the folding support tube 100 after the folding process of the folding support tube 100 has been carried out and the drive module 200 has been assembled.

[0120] In other words, as shown in Figure 11, the first roller 310 and the second roller 320 are connected to the first roller connecting holes 123, 143 and the second roller connecting holes 124, 144, respectively, when the folding support tube 100 is folded.

[0121] The first roller 310 includes a roller body 311 that guides the movement of the urinary catheter 12, and an operating knob 313 that is connected to the roller body 311 and rotated by the user by hand. The roller body 311 is provided to be separated from the operating knob 313.

[0122] The roller body 311 is provided with an outer diameter such that it can be inserted into the first roller coupling holes 123 and 143. Here, the outer circumferential surface of the area in which the roller body 311 is inserted into the first roller coupling holes 123 and 143 may be provided with a reverse rotation prevention projection 315 that protrudes radially outward.

[0123] As shown in Figure 15(a), when the user rotates the operating knob 313 in the forward direction, in which the urinary catheter 12 is inserted into the bladder, the anti-reverse rotation projection 315 of the roller body 311 is guided along the projection guide surface 125a of the uneven portion 125 and moves. On the other hand, when the roller body 311 is rotated in the reverse direction by an external force, that is, in the reverse direction, in which the urinary catheter 12 moves away from the bladder, the anti-reverse rotation projection 315 is inserted into the projection insertion groove 125b and catches between adjacent uneven portions 125. This prevents reverse movement and can prevent the urinary catheter 12 from separating from the bladder.

[0124] The first roller 310 and the second roller 320 may be positioned so as to be spaced apart in accordance with the diameter of the urinary catheter 12. When the user rotates the operating knob 313 to rotate the first roller 310, the second roller 320, which is gear-coupled to the first roller 310, rotates inside the second roller coupling holes 124 and 144, causing the urinary catheter 12, positioned between the first roller 310 and the second roller 320, to move forward or backward due to the frictional force with the rollers.

[0125] The aforementioned drive module 200 may be inserted and installed inside the folding support tube 100 from which the lid surface 141 and bottom surface 142 have been removed. More specifically, as shown in Figures 12 and 13, the drive module 200 may be inserted to a position where the first roller insertion holes 214 and 215 of the drive module 200 are aligned with the first roller coupling holes 123 and 143 of the folding support tube 100, and the second roller insertion holes 223 and 224 of the drive module 200 are aligned with the second roller coupling holes 124 and 144 of the folding support tube 100.

[0126] Once the assembly of the folding support tube 100 and the drive module 200 is complete, the gel can be introduced through the opening of the gel containment space 250, and the Foley catheter 10 can be inserted into the support tube assembly 1 to perform the surgery.

[0127] The front view 110 described above, 1st aspect 120, BackThe folding support tube 100 is formed by folding and gluing the 130, second side surface 140, lid surface 141, and bottom surface 142. The drive module 200, first roller 310, and second roller 320 are then attached to the folding support tube 100 to form a support tube assembly as shown in Figure 13.

[0128] However, before actual use in surgery, specific requirements include the assembly process of the folding support tube 100 and the drive module 200, the pre-insertion process of the Foley catheter, the opening for introducing gel into the gel-containing space, and the opening for inserting the Foley catheter 10 into the inside of the folding support tube 100. Therefore, in this invention, a separate cutting line is formed on the folding support tube 100 in its unfolded form, and the aforementioned opening can be formed by cutting along the cutting line before use.

[0129] Front 110, 1st aspect 120, Back An open channel cut line 112 may be formed on either the 130 or the second side surface 140, along its longitudinal direction, from the bottom of the support tube to a position a predetermined distance away from the bottom of the gel containment space 250 toward the bottom of the support tube.

[0130] In other words, when the unfolded diagram is folded, the opening path cut line 112 is not cut, as shown in Figure 11, so the opening path remains closed. When the medical staff cuts along the opening path cut line 112 before use, the opening path is opened, as shown in Figure 12.

[0131] At this time, the lower part of the open passage is provided with a lower cut line 113 that is inclined toward the surfaces on both sides of the surface on which the open passage cut line 112 is formed. The inclined arrangement of the lower cut line 113 exposes the lower end of the Foley catheter to the outside, making it easier to connect to the urine bag. The lower cut line 113, together with the open passage, faces the front surface 110. 1st aspect 120, BackIt is separated from 130 and the second side surface 140, and the lower part is left open as shown in Figure 13 to secure a space into which a Foley catheter 10 can be inserted.

[0132] The process of using the support pipe assembly 1 according to an embodiment of the present invention having such a configuration will be explained with reference to the attached drawings.

[0133] As shown in Figure 13, the support pipe assembly 1 according to an embodiment of the present invention includes a support pipe 100 and a drive module 200, and a first roller 310 and a second roller 320 connected thereto, which are formed by folding the unfolded drawing.

[0134] The folding support tube 100 may have a waterproof coating on its surface. The Foley catheter 10 is inserted in a folded state, and the first roller 310 and the second roller 320 are connected to the first roller connecting holes 123, 143 and the second roller connecting holes 124, 144, and to the first roller insertion holes 214, 215 and the second roller insertion holes 223, 224, thereby providing the device to medical personnel in an antibacterial and sealed package.

[0135] At the manufacturing site for the folding support tube 100, the folding support tube 100 can be manufactured by folding the unfolded drawing. The worker folds the front 110 along the folding line of the unfolded drawing shown in Figure 10. 1st aspect 120, Back 130 and the second side 140 are bent to form a support tube shape in the form of a square tube.

[0136] Then, the bonding surfaces are bonded together to manufacture a rectangular tubular folding support tube 100 as shown in Figure 11, and the drive module 200 is installed inside the folding support tube 100. The support tube assembly 1 manufactured in this way may be provided to the medical team in sterile packaging with the Foley catheter 10 installed inside.

[0137] When inserting the Foley catheter 10 into the patient, the medical staff opens the packaging of the support tube assembly 1 and cuts the open channel cut line 112 and the lower cut line 113 of the folded support tube 100, as shown in Figure 12, thereby exposing the lower part and open channel of the folded support tube 100 to the outside.

[0138] The gel is introduced into the internal space of the gel-containing space 250 through the opening of the gel-containing space 250, and the Foley catheter 10 is folded and inserted from the bottom to the top of the support tube 100.

[0139] As shown in Figure 16, the urinary catheter 12 and branch tube 14 are sequentially inserted through the open lower part of the folding support tube 100, starting with the insertion tip 11 of the Foley catheter 10, and the insertion tip 11 moves upward through the gel containment space 250 when the medical staff operates the operating knob 313 in the forward direction.

[0140] When the operating knob 313 is operated in the forward direction, the first roller 310 rotates stably along the guide surfaces 125a and 145a inside the first roller coupling holes 123 and 143. When the operating knob 313 is operated in the reverse direction or when the first roller 310 rotates in the reverse direction due to an external force, the reverse rotation prevention projection 315 catches in the insertion groove 125b, preventing reverse rotation.

[0141] As the urinary catheter 12 is moved and the insertion tip 11 is inserted into the bladder as shown in Figure 16, the first separation line 114 and the second separation line 115 are cut, and the pair of third parts in the drive module 200 are opened so that they move away from each other, thereby separating the Foley catheter 10 from the support tube assembly 1.

[0142] Figure 17 shows an unfolded view of a folding support tube according to another embodiment of the present invention.

[0143] In the following, we will omit explanations of parts that are the same as those in the folding support tube 100 in the embodiment shown in Figure 10, and will focus on explaining the differences.

[0144] The folding support tube according to the embodiment shown in Figure 17 is provided such that the syringe 400 can be housed inside the support tube assembly 1. For this purpose, the front surface 110, 1st aspect 120, Back Of the 130 and the second side surface 140, a first cylinder housing cut line 161 is formed in the lateral direction (width direction) of the folding support tube 100 on the remaining surface excluding the surface on which the open passage cut line 112 is formed, and a second cylinder housing cut line 164 is formed in the lateral direction at a predetermined distance from the first cylinder housing cut line 161 in the longitudinal direction. The first cylinder housing cut line 161 and the second cylinder housing cut line 164 are cut, and the connecting portion between the first cylinder housing cut line 161 and the second cylinder housing cut line 164 is folded inward to form a cylinder insertion space N in which the cylinder 410 of the syringe 400 is housed.

[0145] Furthermore, a first piston housing cut line 168 is formed laterally in a portion separated by a predetermined distance in the direction opposite to the direction from the first cylinder housing cut line 161 to the second cylinder housing cut line 164, and a second piston housing cut line 162 is formed laterally in a portion separated by a predetermined distance in the longitudinal direction from the first piston housing cut line 168. The first piston housing cut line 168 and the second piston housing cut line 162 are cut, and the connecting portion between the first piston housing cut line 168 and the second piston housing cut line 162 is folded inward into the folding support tube 100, thereby forming a piston insertion space M into which the piston 420 of the syringe 400 is inserted.

[0146] Referring to Figure 18, the syringe housing 160 forms a cylinder insertion space N into which the cylinder 410 of the syringe 400 is inserted, and a piston insertion space M into which the piston 420 is inserted.

[0147] The cylinder insertion space N is cut by the first cylinder housing cut line 161 and the second cylinder housing cut line 164, and the front surface 110 between the first cylinder housing cut line 161 and the second cylinder housing cut line 164, 1st aspect 120, BackThe connecting portions of 130 and the second side 140 are folded inward into the folding support tube 100, forming a space capable of accommodating the cylinder 410 of the syringe 400.

[0148] The piston insertion space M has a first piston housing cut line 168 and a second piston housing cut line 162, and the front surface 110 between the first piston housing cut line 168 and the second piston housing cut line 162, 1st aspect 120, Back The connecting portions of 130 and the second side 140 are bent inward into the folding support tube 100, forming a space capable of accommodating the piston 420 of the syringe 400.

[0149] The flange insertion cut lines 163 and 166 extend laterally outward from the connecting portion that bends inward on the inside of the folding support tube 100 in the cylinder insertion space N or the piston insertion space M. By cutting out the flange insertion cut lines 163 and 166, a space is created into which the flange 411 of the syringe 400 can be inserted, and the syringe 400 can be fixed within the syringe coupling portion 160. The attached drawing shows how the flange insertion cut lines 163 and 166 are formed in the cylinder insertion space N, but it should be understood that this is not the only way, and the flange insertion cut lines may also be formed in the piston insertion space M.

[0150] The syringe 400 is connected to the fluid supply tube 14a and supplies a fluid such as distilled water, thereby inflating the balloon 13, which is fluid-communicable with the fluid supply tube 14a. The balloon 13 inflation process is preferably performed after the insertion tip 11 has been inserted into the bladder, as the balloon 13 inflation helps to hold the insertion tip 11 in the bladder.

[0151] On the other hand, the folding support tube according to the embodiment of the present invention is particularly noteworthy in that it is further provided with a configuration that forms a medical supplies storage section for storing other medical supplies.

[0152] Front 110, 1st aspect 120, BackOn either surface 130 or the second side surface 140, a surface 151 for forming a medical supplies storage space is provided at a position below the lower cut line 113, and an insertion groove 152 is formed on the surface opposite to the surface on which the medical supplies storage space forming surface 151 is provided.

[0153] A cut line is provided on a portion of the surface 151 that forms the medical supplies storage space. Once the cut is completed along the cut line, the surface 151 acts as a partition wall across the internal space of the folding support tube 100. The cut portion of the surface 151 is inserted into the insertion groove 152, thereby forming a medical supplies storage space from the bottom of the folding support tube 100 to the surface 151. Medical supplies necessary for Foley catheter surgery, such as disinfectant swabs, gels, and distilled water, may be stored in the medical supplies storage space.

[0154] In another embodiment of the present invention, the folding support tube 100 is configured to prevent the backward movement of the Foley catheter 10. This will be explained in detail with reference to Figures 10 and 18.

[0155] The insertion tip 11 of the Foley catheter 10 can be inserted into the bladder, and the balloon 13 can be inflated to fix the urethral catheter 12 in place. This is because the inflated diameter of the balloon 13 is larger than the diameter of the urethra, and the balloon 13 acts as a stopper. Therefore, if the fluid inside the balloon 13 is discharged to the outside and the balloon 13 deflates, the Foley catheter 10 may move backward.

[0156] To prevent this, in the present invention, the front surface 110, 1st aspect 120, Back A configuration may be further provided that constitutes a reverse prevention unit arranged in parallel with either surface 130 or the second side surface 140 (see Figure 10).

[0157] The structure of the reverse prevention mechanism is similar to the principle used to form the storage space for medical supplies.

[0158] Front 110, 1st aspect 120, Back On either surface 130 or the second side surface 140, a reverse prevention section forming surface 171 is provided at a position above the lower cut line 113, and an insertion groove 172 is formed on the surface opposite to the surface on which the reverse prevention section forming surface 171 is provided.

[0159] A cut line is provided on a part of the reverse prevention section forming surface 171, and once the cutting is completed along the cut line, the reverse prevention section forming surface 171 acts as a partition wall that crosses the internal space of the folding support pipe 100, as the cut portion of the reverse prevention section forming surface 171 is inserted into the insertion groove 172.

[0160] The backward movement of the Foley catheter 10 can be prevented by the backward movement prevention surface 171 crossing the inner space of the folding support tube 100.

[0161] Referring to Figure 20, the backward movement of the Foley catheter 10 is prevented by the backward movement prevention surface 171. The branched tube 14 is branched into a fluid injection tube 14a and an outlet tube 14b at one end of the urinary catheter 12. For example, the fluid injection tube 14a includes a portion that extends with a constant incline from the branched portion and a portion that is connected to the extended portion and extends parallel to the outlet tube 14b. By the backward movement prevention surface 171 crossing the inner space of the folding support tube 100, the branched tube (branched tube) of the Foley catheter 10 is stopped by the backward movement prevention surface 171, making it possible to prevent the Foley catheter 10 from moving backward. After surgery, the retraction prevention surface 171 can be detached, and the Foley catheter 10 can be folded and easily separated from the inside of the support tube 100.

[0162] A folding support tube according to yet another embodiment of the present invention will be described with reference to Figure 21.

[0163] The folding support tube shown in Figure 21 is characterized in that, i) an upper cut line 117 is separately formed to open the upper part of the folding support tube, ii) a syringe housing section is formed to accommodate the cylinder and piston, and syringe cover surfaces 181, 182, 183, 184 are further formed to cover the outside of the syringe housed in the syringe housing section, iii) support section cut lines 126, 127, 146, 147 are further formed to form a support section that supports the folding support tube after cutting, and iv) an open path exposure cut line 118 is further formed to expose a part of the open path cut line 112 in order to facilitate cutting the open path cut line 112, and a cut section 119 is further formed.

[0164] The upper cut line 117 is the front 110, 1st aspect 120, Back It is formed across the width direction of 130, the second side surface 140, and the attachment surface 150. When a portion of surfaces 110, 120, 130, 140, and 150 is cut along the upper cut line 117, the upper part of the folding support tube is opened. The aforementioned drive module 200 is then installed from the opened upper part.

[0165] On the other hand, the upper cut line 117 includes a portion 117a that extends in the longitudinal direction of some of the surfaces 110, 120, 130, 140, and 150. The formation of the longitudinally extending portion 117a makes it easier to cut along the upper cut line 117.

[0166] On the other hand, front 110, 1st aspect 120, Back Of the 130 and second side surface 140, a first syringe housing cut line 191 is formed in the width direction of the folding support tube 100 on the remaining surface excluding the surface on which the open passage cut line 112 is formed, and a second syringe housing cut line 192 is formed in the lateral direction at a predetermined distance longitudinally from the first syringe housing cut line 191. The first syringe housing cut line 191 and the second syringe housing cut line 192 are cut, and the connecting portion between the first syringe housing cut line 191 and the second syringe housing cut line 192 is folded inward into the folding support tube 100, thereby forming a space for housing a syringe 400.

[0167] Between the first syringe housing cut line 191 and the second syringe housing cut line 192, flange insertion cut lines 193 and 194 are formed into which the flange of the cylinder 410 is inserted.

[0168] On the other hand, in the folding support tube 100 shown in Figure 21, after the syringe 400 is housed in the syringe housing, syringe cover surfaces 181, 182, 183, and 184 are formed that cover a portion of the outside of the syringe housing.

[0169] The syringe cover surfaces 181, 182, 183, and 184 may be formed sequentially along the width direction on the side of the attachment surface 150, and the connecting portions of each surface can be bent so that the syringe cover surface 184 is inserted into the syringe cover surface insertion space 185, thereby surrounding a portion of the outside of the syringe housing. Therefore, the syringe 400 inserted into the syringe housing is supported from the outside by the syringe cover surfaces 181, 182, 183, and 184.

[0170] On the other hand, the support cut lines 126, 127, 146, and 147 have one side connected to the lower side cut line 113 and the upper cut line 117, and the other side Back 130, 1st aspect It is formed by folding so as to connect with the connecting fold lines of 120 and the second side surface 140. Therefore, after cutting the lower side cut line 113 and the upper cut line 117, cutting the support cut lines 126, 127, 146, and 147 can form support parts that act as legs to support the folding support tube 100. Thus, the support stability of the folding support tube 100 is increased.

[0171] The open path exposure cut line 118 extends in the width direction from the attachment surface 150 to the front surface 110 and the second side surface 140 so that a portion (rear end) of the open path cut line 112 is exposed, and has a predetermined width.

[0172] As shown in Figure 21, the rear end of the open-path cut line 112 is positioned (i.e., exposed) in the space formed when the open-path exposed cut line 118 is cut away. When a user grasps a portion of the exposed open-path cut line 112 and applies force toward the upper end, the open-path cut line 112 is cut away from the front 110. To ensure ease of cutting, a cut portion 119 is formed diagonally inside the open-path cut line 112, and it is preferable that the diagonal direction in which the cut portion 119 is formed is opposite to the cutting direction. Therefore, it is possible to provide support force during the process of cutting the open-path cut line 112.

[0173] On the other hand, a folding support tube according to yet another embodiment of the present invention will be described with reference to Figures 22 and 23.

[0174] Referring to Figure 22, the clip cutting line 149 is 1st aspect 120, Back It may be formed over 130 and the second side surface 140. Back The clip cutting line 149 formed on 130 is Back Formed to cross 130, 1st aspect The clip cut lines 149 formed on 120 and the second side surface 140 are Back The clip may be formed to be inclined so that it moves closer to the tip of the folding support tube as it moves away from the 130 clip cutting line.

[0175] Furthermore, the clip cutting line 159 according to the embodiment of the present invention may be further formed on the attachment surface 150, and its shape may be: 1st aspect Since each surface may have the same shape as the clip cut line 149 formed on the 120 or the second side surface 140, it may partially overlap with the clip cut line 149 when each surface is folded to form a folding support tube.

[0176] When the clip cutting lines 149 and 159 are separated, a clip 500 is installed in the separated portion. Referring to Figure 23, the clip 500 includes a first body 510 and a second body 520. For example, the clip 500 may be made of a synthetic resin having a predetermined strength, such as plastic.

[0177] The first body 510 and the second body 520 are connected to each other at their rear ends, with their front ends separated at a constant distance. These separated portions are inserted into the separated sections of the clip cut lines 149 and 159 and installed on the folding support tube.

[0178] A portion of the Foley catheter 10 is exposed to the outside through the opening of the folding support tube, and a urine bag and syringe are attached to the rear end of the Foley catheter 10. However, due to the characteristics of the folding support tube, which is made of paper, the shape is deformed by the weight of the Foley catheter 10, urine bag, and syringe. Therefore, in this invention, by installing a clip 500 to prevent the opening from opening and to support the weight of the Foley catheter and other components, both the accuracy and ease of the surgery can be ensured.

[0179] The present invention, as described above, has the following effects.

[0180] While providing the same functionality as existing Foley catheter support tubes, it can be manufactured from a flexible material (paper, vinyl, or synthetic resin), thus reducing manufacturing costs.

[0181] The drive module, which provides the driving force to guide the Foley catheter, is manufactured from a material with a predetermined rigidity and installed in the folding support tube, thereby improving the durability of the support tube assembly and the accuracy of the surgery.

[0182] The support tube assembly is provided to the medical team with its top and bottom closed by the bottom and lid before use, and the bottom and lid are removed immediately before application to the patient. This facilitates storage and transport, and allows for long-term maintenance of sterility.

[0183] By incorporating a reverse rotation prevention structure for the transfer roller that guides the Foley catheter into the bladder, the Foley catheter is prevented from detaching from the main roller and sub-roller during storage, and the problem of the Foley catheter separating from the patient's body after being inserted during surgery is resolved.

[0184] Furthermore, by incorporating a backward movement prevention mechanism to prevent the Foley catheter from moving backward, the problem of the Foley catheter detaching from the main roller and sub-roller during storage is solved, and the problem of the Foley catheter retracting and separating from the patient's body during surgery is resolved.

[0185] Furthermore, the inclusion of a medical supplies storage compartment, which can hold various medical supplies required during the surgical procedure of inserting a Foley catheter into the bladder (such as syringes, antiseptic swabs, gel, and distilled water), has the advantage of allowing the medical team to perform the surgery easily without having to prepare other medical supplies needed for the procedure.

[0186] Furthermore, the lower end of the Foley catheter is supported by the fourth and fifth parts, and the upper end is held in place by a retaining member, so that the Foley catheter can be inserted into a fixed position without being deflected in any direction.

[0187] Furthermore, by installing a clip with a predetermined strength on the folding support tube, it is possible to prevent the folding support tube from deforming due to the weight of the components required for urinary catheterization surgery.

[0188] In this specification, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce it. However, these are merely examples, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible from the embodiments of this application. Therefore, the scope of protection of this application should be determined by the claims. [Explanation of Symbols]
