Description

[Technical Field]

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

[0002] Artificial urination involves inserting a ureter into the bladder through the urethra to allow urine to be expelled from the bladder, and a Foley catheter is used when the ureter must be maintained for a certain period of time. Artificial urination using a Foley catheter is widely used to expel urine or measure the amount of urine produced by seriously ill patients, general surgery patients, urinary system surgery patients, or other patients who have difficulty urinating smoothly.

[0003] However, surgery to place a Foley catheter into the bladder requires tedious preparation and surgery procedures. Hospitals must prepare a Foley catheter set in advance, which requires aseptic handling and contains a drape, forceps, a Kelly clamp, and three containers: lubricating jelly, saline solution for the balloon, and disinfectant cotton. During the preparation process, medical staff must open the Foley catheter set, separate the Foley catheter and balloon syringe from their packaging, and place the lubricating jelly, saline solution for the balloon, and disinfectant cotton into their respective containers. Each step requires special care to prevent contamination, making the process tedious and time-consuming. From a hospital management perspective, the Foley catheter set preparation and surgery preparation process increases costs and wastes the labor of highly skilled medical personnel. Therefore, there is a need for the development of devices and methods that can simplify the preparation process.

[0004] For this purpose, an "Assembly for Insertion of a Foley Catheter" in Korean Patent Registration No. 10-1058241 is used.

[0005] 1 is an exemplary view showing a Foley catheter 10 inserted into the bladder B through a Foley catheter assembly 20. The Foley catheter assembly 20 has the advantage of minimizing contamination before inserting the Foley catheter 10 into the bladder, simplifying the surgical procedure for the surgeon. However, the Foley catheter assembly 20 has the disadvantage of being expensive to manufacture, considering that it is a disposable type that is used to insert the Foley catheter 10 into the human body and is discarded after use.

[0006] That is, the conventional Foley catheter assembly 20 has a drawback in that it is manufactured using a synthetic resin material such as plastic by a method such as injection molding, resulting in high manufacturing costs, which increases the material supply and demand costs of hospitals that use the Foley catheter assembly 20.

[0007] The Foley catheter 10 is disposed between a first roller 310 and a second roller 320, and when the first roller 310 and the second roller 320 rotate, the Foley catheter advances due to friction between the rollers and the Foley catheter. The Foley catheter assembly's driving principle is that the Foley catheter advances solely through 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, even if slight resistance is encountered in the advancement of the Foley catheter, the rotation of the lower second roller does not occur, resulting in a problem in which the Foley catheter does not advance at all. Furthermore, the Foley catheter 10 is made of a soft material with a certain degree of elasticity. Therefore, when one side of the roller control knob is pressed and turned, the catheter advances deviating to the left or right rather than center as the first roller rotates. Furthermore, when the Foley catheter is deflected to the maximum deflection position, even if the first roller is rotated, friction between the Foley catheter and the housing occurs, causing only the roller to spin freely, which has the disadvantage of not providing sufficient friction force required for forward movement and preventing further forward movement.

[0008] [Patent Document 1] Korean Patent No. 10-1058241 (2011.08.12) [Patent Document 2] Korean Patent Publication No. 10-2022-0138265 (2022.10.12) Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention provides a foldable support tube that provides the same functions as existing Foley catheter support tubes, but is made of a bendable material (paper, vinyl, or synthetic resin), thereby reducing manufacturing costs. In particular, the object of the present invention is to provide a Foley catheter support tube assembly in which the drive module that guides the Foley catheter has high strength, thereby improving surgical accuracy.

[0010] Another object of the present invention is to provide a driving unit having alignment grooves formed in the rollers to prevent the Foley catheter from moving in a deflected manner. [Means for solving the problem]

[0011] In order to solve the above 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, the drive module including: a first part including sides formed with a pair of first roller insertion holes in which first rollers are installed and a connecting surface between the sides; a second part disposed on the connecting surface of the first part aligned with the pair of first roller insertion holes and formed with a pair of second roller insertion holes in which second rollers are installed; a third part disposed on each side of the first part and each formed with 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 within a space formed by the third part.

[0012] In one embodiment, a distance from a connecting surface of the first part to the first roller insertion hole may be longer than a 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 in which one of the pair of half guide holes is formed, and a lower surface spaced apart from the upper surface in 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 connecting portion between the side surface of the first part and the connecting surface is bent in a direction in which the third parts approach each other, a jelly-containing space surrounded by the upper surface, lower surface, and side surface of the first part may be formed.

[0017] In one embodiment, a leak prevention portion may be formed along a longitudinal direction of a contact surface where the third parts contact each other and are formed on both sides of the first part.

[0018] In one embodiment, at least one of the leak prevention parts may have a coupling part formed thereon for coupling with another leak prevention part.

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

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

[0021] In one embodiment, the half guide hole formed on the upper surface may be positioned closer to the coupling surface of the first part 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 positioned closer to the coupling surface of the first part than the half guide hole formed on the upper surface.

[0023] In one embodiment, gear teeth may be formed on the 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, the distance from the first roller or the second roller to the alignment groove may correspond to the thickness of the Foley catheter.

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

[0027] The present invention also provides a support tube assembly in which the above-mentioned drive module is installed, the support tube assembly including a front surface, a back surface, a first side surface, and a second side surface, wherein an open passage through which the fluid supply tube of the Foley catheter passes is formed in one of the front surface, the back surface, the first side surface, and the second side surface, and a pair of first roller coupling holes aligned with a pair of first roller insertion holes of the first part are formed on both sides of the surface on which the open passage is formed.

[0028] In one embodiment, first and second syringe accommodating section cutout lines may be further formed across the surface on which the open passage is formed and at least three other surfaces, and syringe cover surfaces may be formed to be arranged in parallel in sequence on the sides of the adhesive surface arranged in parallel with the front surface.

[0029] In one embodiment, the first and second syringe housings may be cut along the cutting lines, the connecting portions of the three sides may be folded to form the syringe housings, and the syringe cover surface may be folded to surround the outside of the syringe housings.

[0030] In one embodiment, an upper cut line and a lower cut line of a side surface may be further formed across the front surface, the back surface, the first side surface, and the second side surface, and both side surfaces connected to the surface opposite to the surface on which the open passage is formed may be formed with a first support portion cut line, one side of which is connected to the upper cut line and the other side of which is bent to connect to a connecting portion between the opposite surface and both side surfaces, and a second support portion cut line, one side of which is connected to the lower cut line of the side surface and the other side of which is bent to connect to a connecting portion between the opposite surface and both side surfaces.

[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 that supports a support tube assembly may be formed.

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

[0033] In one embodiment, a cutout portion may be formed in a diagonal direction within the open path cutout line, and the diagonal direction may be a direction inclined in a direction opposite to the direction in which the open path cutout line is cut.

[0034] In one embodiment, clip incision lines for attaching clips may be formed on three surfaces other than the surface on which the open path incision line is formed. [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, the tube can be manufactured from a bendable material (paper, vinyl, or synthetic resin), thereby reducing manufacturing costs.

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

[0038] Before use, the support tube assembly is provided to medical staff with the top and bottom closed by the bottom and lid, and the bottom and lid are removed just before application to the patient, which makes storage and transportation easy and allows the sterility to be maintained for a long time.

[0039] The application of a reverse rotation prevention structure to the transport rollers that guide the Foley catheter into the bladder prevents the Foley catheter from coming off between the main roller and sub-roller during storage, and solves the problem of the Foley catheter being separated from the body after being inserted into the patient's body during surgery.

[0040] In addition, by applying a backward movement prevention configuration that prevents the Foley catheter from moving backward, the Foley catheter is prevented from coming off between the main roller and the sub-roller during storage, and the problem of the Foley catheter inserted into the body of the patient moving backward and becoming separated from the body during surgery is solved.

[0041] In addition, a medical supplies storage compartment is provided that can store various medical supplies (syringes, disinfectant cotton, gel, distilled water, etc.) required during the surgical process of inserting a Foley catheter into the bladder, which has the advantage of allowing medical staff to perform the surgery easily without having to go through the process of preparing other medical supplies required for the surgery.

[0042] In addition, the device is configured to guide the Foley catheter so that it can be inserted vertically for men and horizontally for women, which has the advantage of ensuring ease of surgery for medical staff according to differences in reproductive organ structure between genders.

[0043] In addition, alignment grooves are formed in the rollers that provide the force to move the urethra, and the force is transmitted to the urethra simultaneously by the rotation of the first and second rollers. When driven, the urethra has enough force to withstand the resistance applied to the urethra and be inserted into the body. This allows the urethra to move forward and backward without deflecting to either side, which 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 the pressing member, so that the Foley catheter can be inserted into a fixed position without deflecting back and forth or left and right.

[0045] Furthermore, since a clip having a predetermined strength is attached to the folding support tube, there is an advantage that the folding support tube can be prevented from being deformed due to the weight of the structure required for ureteral surgery. [Brief explanation of the drawings]

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

[0048] Throughout the specification, when a part "comprising" or "including" a certain element, this does not mean that it excludes other elements, but that it may further include other elements, unless otherwise specified. Furthermore, terms such as "unit," "unit," and "module" used in the specification refer to a unit that processes at least one function or operation, and may be embodied as hardware, software, or a combination of hardware and software. Furthermore, in the context of describing the present invention (particularly in the context of the following claims), the terms "a" or "an," "one," "the," and similar related words may be used to mean both the singular and the plural, unless otherwise specified in the specification or clearly contradicted by the context.

[0049] When describing embodiments of the present invention, if a detailed description of a known function or configuration is deemed to obscure the gist of the present invention, the detailed description will be omitted. Furthermore, the terms used below are defined in consideration of the functions in the embodiments of the present invention, and may be changed depending on the intentions or practices of users or operators. Therefore, the definitions should be based on the overall content of this specification.

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

[0051] First, a driving unit according to an embodiment of the present invention will be specifically described with reference to FIGS.

[0052] The driving unit according to an embodiment of the present invention includes a first roller 310 and a second roller 320, and the Foley catheter 10 is disposed between the first roller 310 and the second roller 320, and can move forward due to the frictional force generated between the rollers and the Foley catheter as the first roller 310 and the second roller 320 rotate.

[0053] A drive unit according to the prior art is shown in Fig. 2. Referring to Fig. 2, a first roller body 311 and a second roller body 321 are provided in a cylindrical shape. The Foley catheter 10 is disposed between these cylindrical bodies.

[0054] During Foley catheter insertion surgery, medical staff advance the Foley catheter 10 by rotating the first or second roller while grasping it with one hand. The rotational force of the first or second roller is transmitted to the Foley catheter 10, and the force that moves the Foley catheter 10 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 advance while deflecting to the left or right. Furthermore, once the Foley catheter 10 advances to its maximum deflection position, the Foley catheter 10 cannot advance any further even if the rollers are rotated, resulting in the rollers spinning freely.

[0055] A driving unit according to an embodiment of the present invention for solving the above problems is shown in FIGS.

[0056] As in Fig. 2, Figs. 3 to 6 also include a first roller 310 and a second roller 320, with a Foley catheter 10 disposed between the two rollers. However, while the roller body in Fig. 2 is cylindrical, the roller bodies in Figs. 3 to 6 all differ in that alignment grooves 311a, 311b, 321a, and 321b are formed in the first roller body 311 or the second roller body 321.

[0057] A plurality of 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 with each other and are coupled together. Therefore, even if only one of the first roller 310 and the second roller 320 is operated, both rollers rotate.

[0058] The alignment grooves 321a, 321b are recessed at the center of the main body 311, 321 of each roller 310, 320. Specifically, the alignment grooves 321a, 321b are recessed from the outer surface of the first roller 310 or the second roller 320 in a direction away from the Foley catheter 10. The grooves may be recessed in shapes including, but not limited to, those shown in FIGS. 3 to 6. While FIGS. 3 to 6 show alignment grooves 321a, 321b formed in the second roller, an embodiment in which the alignment grooves are formed in the first roller is also within the scope of the present invention.

[0059] Meanwhile, the distance from the center of the first roller body 311 to the alignment grooves and the distance d from the center of the second roller body 321 to the alignment grooves 311a, 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 d may be smaller than the diameter of the Foley catheter 10. This increases the contact area between the rollers and the Foley catheter, so that the frictional force caused by the rotation of the rollers can be reliably transmitted to the Foley catheter 10, even when the Foley catheter 10 is placed in the alignment grooves. Therefore, the Foley catheter 10 can be advanced and inserted into the body with less force.

[0060] Furthermore, the width of alignment grooves 321a, 321b also preferably corresponds to the thickness (diameter) of Foley catheter 10. Specifically, the width may be the same as the diameter of Foley catheter 10, and preferably, the width is larger than the diameter of Foley catheter 10. A larger width means that the space for deflection of Foley catheter 10 to the left or right is wider, so the width is preferably 1 to 1.5 times the diameter of Foley catheter 10.

[0061] Meanwhile, the gear teeth of roller bodies without 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 alignment grooves 321a and 321b, which are a closed space, and even when the rollers are rotated, the Foley catheter 10 only deflects within the closed space and can move forward while roughly positioned at the center of the roller body. This minimizes the patient's pain and reduces the difficulty of the surgery.

[0062] Next, a driving module 200 according to an embodiment of the present invention will be described in detail with reference to Figures 7 to 9. The driving unit described above is installed in the driving module 200 according to the embodiment of the present invention, and the driving module 200 may be manufactured from a material that is inexpensive, has a certain strength, and is easy to mold, such as plastic, but is not particularly limited thereto. In other words, the driving module 200 is configured to have the driving unit installed therein and to serve as a support for supporting the installed driving unit.

[0063] The drive module 200, which is equipped with a drive unit according to an embodiment of the present invention, is installed in the folding support tube 100 described below, and provides a driving force for inserting the ureter 12 of the Foley catheter 10 into the genitals of the patient, specifically, inserting the insertion tip 11 of the Foley catheter 10 into the bladder.

[0064] 7, the drive module 200 includes a first part 210, a second part 220, a third part 230, and a fourth part 240. The drive module 200 can be configured by integrating the respective parts, but in other embodiments, the drive module 200 can also be configured by assembling the parts in separate forms.

[0065] The first part 210 includes side surfaces 211 and 212 having a pair of first roller insertion holes 214 and 215 in which the first roller 310 is installed, and a connecting surface 213 between the side surfaces 211 and 212. The pair of first roller insertion holes 214 and 215 may be recessed inward (toward the connecting surface) from the outermost edges of the side surfaces 211 and 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 and a pair of first roller insertion holes 214, 215 of the driving module 200, which will be described later.

[0067] An insertion protrusion 271 is formed on one of the side surfaces 211, 212 to be coupled to an insertion groove 272 formed on the other side surface 211. When the insertion protrusion 271 is coupled to the insertion groove 272 while the side surfaces 211, 212 move toward each other, the folded shape of the driving module 200 can be fixed. The driving module 200 in a state where the folded shape is fixed can be inserted into the folding support tube 100 shown in FIG. 12 to assemble the support tube assembly.

[0068] The second part 220 is disposed on the connecting surface 213 of the first part 210 and includes side surfaces 221 and 222 having a pair of second roller insertion holes 223 and 224 formed therein, in which the second roller 320 is installed. The pair of second roller insertion holes 223 and 224 may be recessed inward (toward the connecting surface) from the outermost edges of the side surfaces 221 and 222. In another example, the second roller insertion holes 223 and 224 may be formed penetrating the side surfaces 211 and 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, and in another example, may be placed on the second roller insertion holes 223, 224 of the second part 220.

[0070] Preferably, 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, the difference corresponding to the thickness of the urethra 12. The urethra 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 operating the first roller 310 (specifically, by operating the operating knob). The difference corresponds to the thickness of the urethra 12, so that the rotational force of the first roller 310 and the second roller 320 can be reliably transmitted to the urethra 12. This achieves the advantage of enabling Foley catheter insertion surgery with less force.

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

[0072] In the following, one third part 230 will be taken as an example for explanation.

[0073] The third part 230 is formed with a pair of half guide holes 233, 234 for guiding the urethra 12, and includes an upper surface 231 and a lower surface 232 in 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 urethra 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] The pair of third parts 230 are arranged opposite each other, and when they are connected to each other, the two half guide holes come together to form a complete pair of guide holes, through which the urethra 12 passes.

[0076] When inserting a Foley catheter, the patient is required to lie down during surgery. Due to the characteristics of the human anatomy, the catheter should be inserted vertically in male patients and horizontally in female patients.

[0077] Therefore, during a Foley catheter insertion operation, for a male, if the Foley catheter is pointing downward, the surgeon can easily fold and grasp the support tube 100 to insert the catheter, and for a female, if the Foley catheter is pointing horizontally, the surgeon can easily fold and grasp the support tube 100 to insert the catheter.

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

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

[0080] In another embodiment of the present invention, the half guide hole 233 formed in the upper surface 231 is positioned higher than the half guide hole 234 formed in the lower surface 232 (i.e., positioned farther from the connecting surface of the first part), and the catheter passes through the guide hole and moves upward. This allows the Foley catheter 10 to be inserted horizontally and easily, naturally, according to the angle of the surgeon's wrist when holding the support tube assembly in the hand. This effect is maximized when performing surgery on female subjects.

[0081] Meanwhile, the pair of third parts 230 may be disposed perpendicular to the side surfaces 211, 212 of the first part 210, respectively. 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, by connecting the third parts to each other, a gel-containing space 250 is formed, surrounded by the upper surface 231 and the lower surface 232 of the third part 230 and the side surfaces 211, 212 of the first part 210. Gel is contained in the gel-containing space 250, and the gel (jelly) is applied to the urethra 12 passing through the gel-containing space 250. Applying the gel to the urethra 12 minimizes friction between the urethra 12 and the bladder during insertion, thereby facilitating insertion of the urethra 12 and minimizing pain to the patient.

[0082] Leak prevention portions 235 and 236 are formed on a portion of the contact surface where the third parts 230 come into contact with each other. The leak prevention portions 235 and 236 are formed along the longitudinal direction of the contact surface, and each leak prevention portion 236 has a coupling portion 237 for coupling with another leak prevention portion 235. The coupling portion 237 may be formed, for example, in the shape of a hook with a groove formed in the center, and another leak prevention portion 235 can be coupled to the groove to couple the third parts 230 together. The leak prevention portions 235 and 236 strengthen the sealing ability of the gel containing space 250, preventing the gel contained in the gel containing space 250 from leaking out.

[0083] The fourth part 240 is disposed inside the gel containing 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 side surfaces 211 and 212 of the first part 210 and the connecting surface 213 may be thinner than other portions. The thinner portion allows the side surfaces 211 and 212 to bend toward each other in the direction in which the third part 230 approaches each other, thereby completing the shape of the driving module 200.

[0084] The fourth part 240 is aligned with the third part 230 in the width direction and is disposed inside the gel-containing space 250 formed by bending the side surfaces 211 and 212 toward each other. The fourth part 240 has a predetermined height, so that it can provide the third part 230 with predetermined durability and rigidity.

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

[0086] Meanwhile, the upper surface of the fourth part 240 may be formed with an inclination such that its height decreases toward the guide groove 241. The fourth part 240 is disposed inside the gel-containing space 250. Because the height of the upper surface of the fourth part 240 decreases toward the guide groove 241, the gel inside the gel-containing space 250 can collect in the guide groove 241, and therefore, a larger amount of gel can be applied to the urethra 12 passing through the guide groove 241.

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

[0088] That is, in an embodiment in which the guide hole of the third part 230 becomes lower from the lower surface 232 to the upper surface 231 to make it easier to insert the catheter in a male subject, it is preferable that the guide groove 241 of the fourth part 240 is also formed lower from the lower surface 232 to the upper surface 231 (see Figure 9(b)).

[0089] In addition, in an embodiment in which the guide hole of the third part 230 becomes higher from the lower surface 232 to the upper surface 231 to make it easier to insert the catheter in a female subject, it is preferable that the guide groove 241 of the fourth part 240 is also formed so as to become higher 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 second roller insertion holes 223, 224 in which the first roller 310 and second roller 320 are installed, i.e., closer to the patient than the rollers.

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

[0092] Similarly to the fourth part 240, the fifth part 260 has a groove 261 formed therein 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 with each other. Thus, the Foley catheter 10 may be supported by the fourth part 240 and the fifth part 260 in the front and rear of the roller, and the fourth and fifth parts have grooves formed therein for guiding the movement of the Foley catheter 10, facilitating insertion of the Foley catheter 10.

[0093] In addition, a pressing member 280 may be formed on one of the side surfaces 211, 212. The pressing member 280 is formed to protrude at a position farther from the connecting surface 213 than the half guide holes 233, 234. With the Foley catheter 10 as a reference, the lower part is supported by the fourth part 240 and the upper part is pressed by the pressing member 280, which prevents the Foley catheter 10 from being inserted into an unintended position.

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

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

[0096] The foldable support tube 100 according to an embodiment of the present invention is provided in the form of an unfolded view as shown in Fig. 10, and medical staff can fold each component along the folding lines in the unfolded view and cut off some components along the cutting lines to form the support tube assembly 1. In another embodiment, the foldable support tube 100 can be provided to medical staff in a pre-folded state, packaged with a Foley catheter.

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

[0098] The developed view of the foldable support tube 100 according to the embodiment of the present invention includes multiple surfaces, including a front surface 110, a back surface 120, a first side surface 130, and a second side surface 140, which are arranged side by side. Here, the "parallel arrangement" means that the Foley catheter 10 is arranged in a direction transverse to the Foley catheter 10 when the Foley catheter 10 is provided inside the foldable support tube 100, and the "serial arrangement" means that the Foley catheter 10 is arranged in a direction parallel to the Foley catheter 10.

[0099] The front surface 110, rear surface 120, first side surface 130, and second side surface 140 can be bent along bending lines 111, 131, and 132 located at the connecting surfaces of each surface to form a rectangular tube. The order of the arrangement of the front surface 110, rear surface 120, first side surface 130, and second side surface 140 can be changed within the range that allows the rectangular tube shape to be formed. In other embodiments, support tubes of various polygonal shapes can be formed, such as a circular tube with a circular cross section, a pentagonal tube with a pentagonal cross section, or a hexagonal tube with a hexagonal cross section.

[0100] 10, the solid line indicated by a represents the bending line, the dotted line indicated by b represents the cutting line to be cut by the user (e.g., medical staff) before surgery, the solid line indicated by c represents the cutting line to be cut after inserting a Foley catheter, and the hatched area indicated by d represents the adhesive surface that is folded and bonded to other surfaces. The bending line may be formed to be thinner than other areas, i.e., the bending line is formed by being recessed to a certain depth compared to other areas, so that when the user applies external force, the surfaces on both sides of the bending line bend together and maintain the folded state.

[0101] The front surface 110 , the back surface 120 , the first side surface 130 , and the second side surface 140 are folded together to form the sides of the support tube assembly 1 .

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

[0103] The cover surface 141 and the bottom surface 142 are configured to form the top and bottom surfaces of the support tube assembly 1, respectively, and may be arranged in series with any one of the front surface 110, rear surface 120, first side surface 130, and second side surface 140. For example, the cover surface 141 may be arranged in series with the front surface 110, and the bottom surface 142 may be arranged in series with the rear surface 120, or they may be arranged in series on the same plane. Because the front surface 110, rear surface 120, first side surface 130, and second side surface 140 are bent relative to each other to form a polygonal prism, the cover surface 141 and the bottom surface 142 form the top and bottom surfaces of the support tube assembly 1 through the bending process, even if they are only arranged in series with any one of the front surface 110, rear surface 120, first side surface 130, and second side surface 140.

[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, and the adhesive surfaces are folded and attached to the adjacent other surfaces to form the folded support tube 100.

[0105] The cover surface 141 and the bottom surface 142 together cover the top and bottom of the folding support tube 100 and serve to prevent foreign matter from entering the inside of the folding support tube 100 .

[0106] The folding support tube 100 may be provided to medical staff in a package with the cover surface 141 and the bottom surface 142 covered and the respective cut lines left untouched. When performing surgery, the tube is used after removing the cover surface 141 and the bottom surface 142 by cutting the opening cut line 112, the side lower cut line 113, the gel insertion hole cover 116, etc.

[0107] A cut line for the gel insertion hole cover 116 is formed at a corresponding position between the upper end of the open passage and the cover surface 141 on any one of the front surface 110, rear surface 120, first side surface 130, and second side surface 140. The cut line is cut to form a cut line for the gel insertion hole cover 116 that communicates with the internal space of the gel containing space 250. When the cut line for the gel insertion hole cover is cut, an opening (gel insertion hole) of the gel containing space 250 is located at the cut portion, and the user can pour gel into the gel containing space 250 through the opening.

[0108] The first separation perforation line 114 extends from the open path perforation line 112 to the gel insertion hole perforation line, and the second separation perforation line 115 extends from the gel insertion hole perforation line to the connecting portion connected to the cover surface 141. The first separation perforation line 114 and the second separation perforation 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] A lower adhesive surface and an upper adhesive surface may be provided at a certain area on the lower end and upper end of any one of the front surface 110, rear surface 120, first side surface 130, and second side surface 140. FIG. 10 shows that a lower adhesive surface 142a and an upper adhesive surface 141a are provided at the lower end and upper end of the second side surface 140, respectively. The lower adhesive surface 142a and the upper adhesive surface 141a are adhered to the bottom surface 142 and the cover surface 141 when the second side surface 140 is folded and assembled into the foldable support tube 100 as shown in FIG. 11, thereby maintaining the shape of the foldable support tube 100. In addition, a side adhesive surface 117 may be provided at an edge of the front surface 110, and may be adhered to the rear surface 120 when the foldable support tube 100 is folded and assembled. However, this is only one example of the adhesive surfaces formed, and any number of embodiments are possible in which a lower adhesive surface and an upper adhesive surface are provided on one of the four surfaces 110, 120, 130, and 140 with a certain area.

[0110] The folding support tube 100, which has a front surface 110, a rear surface 120, a first side surface 130, and a second side surface 140, etc., formed by folding, may have a first roller 310 and a second roller 320 for transporting the urethra 12.

[0111] That is, the first roller 310 and the second roller 320 are assembled to the folding support tube 100 in a folded state (see FIG. 11), and the folding support tube 100 can be prepared as shown in FIG.

[0112] To this end, a pair of first roller coupling holes 123, 143 into which the first roller 310 is inserted may be formed through one of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140 and the surface facing 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 spaced apart from the pair of first roller coupling holes 123, 143 in the horizontal direction (width direction).

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

[0114] As shown in Figure 11, a first roller 310 is coupled to the first roller coupling holes 123, 143. An oval-shaped pressing cut line 143a is formed in the first roller coupling hole 143. When the first roller 310 is assembled and rotated to transport the urethra 12, the pressing cut line 143a is pressed and cut by the rotational pressure of the first roller 310, thereby appropriately compressing the urethra 12 and supporting smooth insertion of the urethra 12 into the patient.

[0115] At this time, 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] 15 is an example of a reverse rotation prevention structure. As shown in FIG. 15, to prevent reverse rotation, the inner surfaces of the first roller coupling holes 123 and 143 are formed with concave and convex portions 125 and 145 extending in the direction of rotation of the first roller 310. The concave and convex portions 125 and 145 are formed in the form of guide surfaces 125a formed with a certain length along the direction of rotation of the first roller 310 on the inner surfaces of the first roller coupling holes 123 and 143. In this case, protrusion insertion grooves 125b are formed between adjacent guide surfaces 125a, into which reverse rotation prevention protrusions 315 protruding from the outer surface of the first roller 310 are inserted when the first roller 310 rotates in the reverse direction.

[0117] Meanwhile, the uneven portion 125, 145 includes a first uneven surface 125c that is curved with a first curvature from the inner peripheral surface of the first roller coupling hole in the circumferential direction, and a second uneven surface 125d that is curved with a second curvature different from the first curvature from the inner peripheral surface in the circumferential direction, the second uneven surface being connected to the first uneven surface at one point (see FIG. 15).

[0118] The second roller 320 is inserted into the second roller coupling holes 124, 144, and the urethra 12 is positioned in the space between the first roller 310 and the second roller 320, with one side contacting the first roller 310 and the other side contacting the second roller 320. That is, when the first roller 310 is rotated, the side of the urethra 12 opposite to 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.

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

[0120] That is, as shown in FIG. 11, the first roller 310 and the second roller 320 are coupled to the first roller coupling holes 123, 143 and the second roller coupling holes 124, 144 when the folding support tube 100 is in a folded state.

[0121] The first roller 310 includes a roller body 311 that guides the transfer of the urethra 12, and an operation knob 313 that is coupled to the roller body 311 and that is manually rotated by the user. The roller body 311 is provided separate from the operation knob 313.

[0122] The roller body 311 has an outer diameter that allows it to be inserted into the first roller coupling holes 123 and 143. Here, a reverse rotation prevention protrusion 315 that protrudes radially outward may be provided on the outer circumferential surface of the region where the roller body 311 is inserted into the first roller coupling holes 123 and 143.

[0123] As shown in Figure 15(a), when the user rotates the operating knob 313 in the forward direction so that the urethra 12 is inserted into the bladder, the reverse rotation prevention projections 315 of the roller body 311 are guided along the projection guide surfaces 125a of the uneven portions 125. 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 so that the urethra 12 moves away from the bladder, the reverse rotation prevention projections 315 are inserted into the projection insertion grooves 125b and become caught between adjacent uneven portions 125. This prevents reverse movement and separation of the urethra 12 from the bladder.

[0124] The first roller 310 and the second roller 320 may be spaced apart in accordance with the diameter of the urethra 12. When the user rotates the operation 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, 144, and the urethra 12, which is positioned between the first roller 310 and the second roller 320, moves forward or backward due to the frictional force with the rollers.

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

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

[0127] The folding support tube 100 is formed by folding and bonding the front surface 110, rear surface 120, first side surface 130, second side surface 140, cover surface 141, and bottom surface 142 described above, and the driving module 200, first roller 310, and second roller 320 can be combined with the folding support tube 100 to form a support tube assembly such as that shown in Figure 13.

[0128] However, before use in an actual surgery, specific openings are required, such as an assembly process for the folding support tube 100 and the drive module 200, an opening for injecting gel into the gel storage space during the pre-insertion process of the Foley catheter, and an opening for inserting the Foley catheter 10 into the folding support tube 100. Therefore, in the present invention, a separate cutting line is formed on the folding support tube 100 in the developed view form, and the openings can be formed by cutting out a portion of the structure along the cutting line before use.

[0129] An open path cutout line 112 may be formed along the longitudinal direction of any one of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140 from the bottom of the support tube to a position spaced a predetermined distance from the bottom of the gel-containing space 250 toward the bottom of the support tube.

[0130] That is, when the developed view is folded, the opening path cutting line 112 is not cut as shown in FIG. 11, so the opening path remains unopened, and when the medical staff cuts along the opening path cutting line 112 before use, the opening path is opened as shown in FIG. 12.

[0131] At this time, the lower part of the open channel is provided with lower cut lines 113 that are inclined toward both sides of the surface where the open channel cut line 112 is formed. By slanting the lower cut lines 113, the lower end of the Foley catheter is exposed to the outside, facilitating connection to a urinal bag. The lower cut lines 113, together with the open channel, are separated from the front 110, back 120, first side 130, and second side 140, and open the lower part as shown in FIG. 13 to ensure a space into which the Foley catheter 10 can be inserted.

[0132] The process of using the support tube assembly 1 according to the embodiment of the present invention having the above-described configuration will be described with reference to the accompanying drawings.

[0133] As shown in FIG. 13, the support tube assembly 1 according to the embodiment of the present invention includes a support tube 100 that is folded in a developed view, a driving module 200, and a first roller 310 and a second roller 320 coupled thereto.

[0134] The surface of the folded support tube 100 may be waterproof coated, and the Foley catheter 10 is inserted into the folded support tube 100. The first roller 310 and the second roller 320 are then coupled to the first roller coupling holes 123, 143 and the second roller coupling holes 124, 144, and the first roller insertion holes 214, 215 and the second roller insertion holes 223, 224, and the tube is then antibacterial, sealed, and provided to medical personnel.

[0135] At the manufacturing site for the foldable support tube 100, the unfolded view can be folded to manufacture the foldable support tube 100. A worker folds the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140 along the folding lines of the unfolded view shown in FIG. 10 to form a rectangular support tube shape.

[0136] 11, the respective adhesive surfaces are bonded together to manufacture the folded support tube 100 in the form of a square tube, and the drive module 200 is installed inside the folded support tube 100. The support tube assembly 1 manufactured in this manner may be sterilized and packaged with the Foley catheter 10 attached thereto, and then provided to medical staff.

[0137] When inserting the Foley catheter 10 into a patient, the medical staff opens the wrapping of the support tube assembly 1 and cuts off the open path 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 path of the folded support tube 100 to the outside.

[0138] Gel is poured 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 FIG. 16, the ureter 12 and branch tube 14 are inserted sequentially starting from the insertion tip 11 of the Foley catheter 10 through the open lower part of the folding support tube 100, and the medical staff operates the operating knob 313 in the forward direction, so that the insertion tip 11 moves upward through the gel-receiving space 250.

[0140] At this time, when the operating knob 313 is operated in the forward direction, the first roller 310 rotates stably along the guide surfaces 125a, 145a inside the first roller coupling holes 123, 143, and when the operating knob 313 is operated in the reverse direction or when an external force causes the first roller 310 to rotate in the reverse direction, the reverse rotation prevention protrusion 315 gets caught in the insertion groove 125b, preventing the reverse rotation.

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

[0142] FIG. 17 is a development view of a folding support tube according to another embodiment of the present invention.

[0143] In the following, a description of the same parts as those of the folding support tube 100 according to the embodiment of FIG. 10 will be omitted, and the description will focus on the parts that are different.

[0144] 17 is provided so that a syringe 400 can be accommodated inside the support tube assembly 1. To this end, a first cylinder accommodating portion cutout line 161 is formed in the lateral direction (width direction) of the foldable support tube 100 on the remaining surfaces of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140, excluding the surface on which the open path cutout line 112 is formed, and a second cylinder accommodating portion cutout line 164 is formed in the lateral direction at a portion spaced a predetermined distance longitudinally from the first cylinder accommodating portion cutout line 161. The first cylinder accommodating portion cutout line 161 and the second cylinder accommodating portion cutout line 164 are cut, and a connecting portion between the first cylinder accommodating portion cutout line 161 and the second cylinder accommodating portion cutout line 164 may be bent inward of the foldable support tube 100 to form a cylinder insertion space N in which the cylinder 410 of the syringe 400 is accommodated.

[0145] In addition, a first piston accommodating portion cutout line 168 is formed in the horizontal direction at a portion spaced a predetermined distance from first cylinder accommodating portion cutout line 161 in the direction opposite to the direction toward second cylinder accommodating portion cutout line 164, and a second piston accommodating portion cutout line 162 is formed in the horizontal direction at a portion spaced a predetermined distance longitudinally from first piston accommodating portion cutout line 168. By cutting first piston accommodating portion cutout line 168 and second piston accommodating portion cutout line 162 and folding a connecting portion between first piston accommodating portion cutout line 168 and second piston accommodating portion cutout line 162 toward the inside of folding support tube 100, a piston insertion space M into which piston 420 of syringe 400 is inserted may be formed.

[0146] Referring to FIG. 18, the syringe receiving portion 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 a space capable of accommodating the cylinder 410 of the syringe 400, which is formed by cutting the first cylinder accommodating section cutout line 161 and the second cylinder accommodating section cutout line 164, and folding the connecting portions of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140 between the first cylinder accommodating section cutout line 161 and the second cylinder accommodating section cutout line 164 toward the inside of the folding support tube 100.

[0148] The piston insertion space M is a space capable of accommodating the piston 420 of the syringe 400, which is formed by cutting the first piston accommodating section cut line 168 and the second piston accommodating section cut line 162, and folding the connecting portions of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140 between the first piston accommodating section cut line 168 and the second piston accommodating section cut line 162 toward the inside of the folding support tube 100.

[0149] The flange insertion cutout lines 163, 166 extend laterally outward from the connecting portion of the cylinder insertion space N or the piston insertion space M that folds inward of the folding support tube 100, and by cutting out the flange insertion cutout lines 163, 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 part 160. While the accompanying drawings show the flange insertion cutout lines 163, 166 formed in the cylinder insertion space N, it should be understood that the flange insertion cutout lines may also be formed in the piston insertion space M, without being limited thereto.

[0150] The syringe 400 is connected to the fluid supply tube 14a and supplies a fluid such as distilled water to inflate the balloon 13, which is fluidly connected to the fluid supply tube 14a. The inflation process of the balloon 13 is preferably performed after the insertion tip 11 is inserted into the bladder, and inflation of the balloon 13 can hold the insertion tip 11 in the bladder.

[0151] Meanwhile, the folding support tube according to the embodiment of the present invention is special in that it further includes a structure for forming a medical supply storage section for storing other medical supplies.

[0152] A medical supply storage space forming surface 151 is provided below the lower cutout line 113 on any one of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140, and an insertion groove 152 is formed on the surface opposite to the surface on which the medical supply storage space forming surface 151 is provided.

[0153] A cut line is provided on a portion of the surface 151 forming the space for accommodating medical supplies, and when cutting is completed along the cut line, the surface 151 functions as a partition across the interior space of the foldable support tube 100. The cut portion of the surface 151 forming the space for accommodating medical supplies is inserted into the insertion groove 152, thereby forming a space for accommodating medical supplies from the bottom of the foldable support tube 100 to the surface 151 forming the space for accommodating medical supplies. Medical supplies required for Foley catheter surgery, such as disinfectant cotton, gel, and distilled water, may be stored in the space for accommodating medical supplies.

[0154] In a folding support tube 100 according to another embodiment of the present invention, a backward movement prevention portion is applied to prevent backward movement of the Foley catheter 10. This will be described in detail with reference to FIGS. 10 and 18.

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

[0156] To prevent this, the present invention may further include a structure that forms a reverse movement prevention part that is arranged in parallel with any one of the front 110, rear 120, first side 130, and second side 140 (see FIG. 10).

[0157] The structure of the reverse movement prevention portion is similar to the principle of forming a medical supply storage space.

[0158] A reverse travel prevention part forming surface 171 is provided at a position above the lower cut line 113 on any one of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140, and an insertion groove 172 is formed on the surface opposite to the surface on which the reverse travel prevention part forming surface 171 is provided.

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

[0160] The backward movement prevention portion forming surface 171 may cross the inner space of the folding support tube 100, thereby preventing the Foley catheter 10 from moving backward.

[0161] Referring to Figure 20, the backward movement of the Foley catheter 10 is prevented by the backward movement prevention portion-forming surface 171. The branch tube 14 branches into a fluid injection tube 14a and a discharge tube 14b at one end of the ureter 12. For example, the fluid injection tube 14a includes a portion extending at a constant incline from the branched portion and a portion connecting to the extended portion and extending parallel to the discharge tube 14b. The backward movement prevention portion-forming surface 171 crosses the inner space of the foldable support tube 100, so that the branched tube (branched tube) of the Foley catheter 10 is stopped by the backward movement prevention portion-forming surface 171, preventing the Foley catheter 10 from moving backward. After surgery, the backward movement prevention portion-forming surface 171 can be separated, allowing the Foley catheter 10 to be easily separated from the inside of the foldable support tube 100.

[0162] Referring to FIG. 21, a folding support tube according to still another embodiment of the present invention will be described.

[0163] The folding support tube shown in FIG. 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 accommodating portion is formed to accommodate all of the cylinder and piston, and syringe cover surfaces 181, 182, 183, and 184 are further formed to cover the outside of the syringe accommodated in the syringe accommodating portion, iii) support portion cut lines 126, 127, 146, and 147 are further formed to form a support portion that supports the folding support tube after cutting, and iv) an opening path exposing cut line 118 is further formed to expose a portion of opening path cut line 112 to facilitate cutting of opening path cut line 112, and an incision portion 119 is further formed.

[0164] The upper cutout line 117 is formed across the width 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 parts of the surfaces 110, 120, 130, 140, and 150 are cut out along the upper cutout line 117, the top of the folding support tube is opened. Then, the aforementioned driving module 200 is installed through the opened top.

[0165] Meanwhile, upper cutting line 117 includes portion 117a extending in the longitudinal direction of some of surfaces 110, 120, 130, 140, and 150. By forming portion 117a extending in the longitudinal direction, cutting along upper cutting line 117 can be performed more easily.

[0166] Meanwhile, a first syringe accommodating section cutout line 191 is formed in the width direction of the folding support tube 100 on the remaining surfaces of the front surface 110, the back surface 120, the first side surface 130, and the second side surface 140, excluding the surface on which the open path cutout line 112 is formed, and a second syringe accommodating section cutout line 192 is formed in the horizontal direction at a portion spaced a predetermined distance longitudinally from the first syringe accommodating section cutout line 191. After the first syringe accommodating section cutout line 191 and the second syringe accommodating section cutout line 192 are cut, a connecting portion between the first syringe accommodating section cutout line 191 and the second syringe accommodating section cutout line 192 may be folded inward of the folding support tube 100, thereby forming a space for accommodating the syringe 400.

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

[0168] On the other hand, in the folding support tube 100 shown in FIG. 21, after the syringe 400 is accommodated in the syringe accommodating portion, syringe cover surfaces 181, 182, 183, and 184 are formed to cover part of the outside of the syringe accommodating portion.

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

[0170] Meanwhile, the support portion cut lines 126, 127, 146, and 147 are formed by bending so that one side is connected to the side lower cut line 113 and the upper cut line 117, and the other side is connected to the connecting folding lines of the first side surface 130, the rear surface 120, and the second side surface 140. Therefore, by cutting the side lower cut line 113 and the upper cut line 117 and then cutting the support portion cut lines 126, 127, 146, and 147, support portions that act as legs supporting the folded support tube 100 can be formed. This increases the support stability of the folded support tube 100.

[0171] The open path exposing 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 part (rear end) of the open path exposing line 112 is exposed, and has a predetermined width.

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

[0173] Meanwhile, a folding support tube according to still another embodiment of the present invention will be described with reference to FIGS.

[0174] 22, clip cut lines 149 may be formed across the rear surface 120, the first side surface 130, and the second side surface 140. The clip cut lines 149 formed on the first side surface 130 may be formed to cross the first side surface 130, and the clip cut lines 149 formed on the rear surface 120 and the second side surface 140 may be formed to incline in a direction approaching the tip of the folding support tube as they move away from the clip cut line on the first side surface 130.

[0175] In addition, the clip cutout line 159 according to an embodiment of the present invention may be further formed on the attachment surface 150, and its shape may be the same as the clip cutout line 149 formed on the back surface 120 or the second side surface 140, so that it may partially overlap with the clip cutout line 149 when each surface is folded to form the folded support tube.

[0176] When the clip incision lines 149 and 159 are cut, the clip 500 is installed in the cut portion. Referring to Fig. 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 and spaced apart at a predetermined distance from each other at their front ends, and are inserted into the cutouts of the clip incisions 149 and 159 to be folded and attached to the support tube.

[0178] A portion of the Foley catheter 10 is exposed to the outside through the open passage of the folded support tube, and a drainage bag and syringe are connected to the rear end of the Foley catheter 10. However, due to the characteristics of the folded support tube being made of paper, there is a problem that the shape of the Foley catheter 10 may be deformed by the weight of the Foley catheter 10, drainage bag, and syringe. Therefore, in the present invention, a clip 500 is installed to prevent the open passage from opening and to support the weight of the Foley catheter, etc., thereby ensuring the accuracy and ease of surgery.

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

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

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

[0182] Before use, the support tube assembly is provided to medical staff with the top and bottom closed by the bottom and lid, and the bottom and lid are removed just before application to the patient, which makes storage and transportation easy and allows the sterility to be maintained for a long time.

[0183] The application of a reverse rotation prevention structure to the transport rollers that guide the Foley catheter into the bladder prevents the Foley catheter from coming off between the main roller and sub-roller during storage, and solves the problem of the Foley catheter being separated from the body after being inserted into the patient's body during surgery.

[0184] In addition, by applying a backward movement prevention configuration that prevents the Foley catheter from moving backward, the Foley catheter is prevented from coming off between the main roller and the sub-roller during storage, and the problem of the Foley catheter inserted into the body of the patient moving backward and becoming separated from the body during surgery is solved.

[0185] In addition, a medical supplies storage compartment is provided that can store various medical supplies (syringes, disinfectant cotton, gel, distilled water, etc.) required during the surgical process of inserting a Foley catheter into the bladder, which provides the advantage of allowing medical staff to easily perform the surgery without having to prepare other medical supplies.

[0186] Furthermore, the lower end of the Foley catheter is supported by the fourth and fifth parts, and the upper end is held down by the holding member, so that the Foley catheter can be inserted into a fixed position without deflecting back and forth or left and right.

[0187] Furthermore, since a clip having a predetermined strength is attached to the folding support tube, there is an advantage in that the problem of the folding support tube being deformed due to the weight of the structure required for ureteral surgery can be prevented.

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