Description

[Technical Field]

[0001] This invention relates to an insertion aid used when inserting the insertion end of a bladder balloon catheter into the urethra and bladder, and then, after insertion is complete, inflating the balloon by injecting balloon inflation water into the insertion end of the catheter using a syringe connected to a balloon funnel at the opposite end of the catheter from the insertion end. [Background technology]

[0002] BACKGROUND ART Conventionally, a catheter that is inserted into the bladder via the urethra and left therein is disclosed, for example, in Patent Document 1.

[0003] An example of this type of catheter is a bladder balloon catheter 100 as shown in Figure 11, which comprises a long silicone rubber catheter body 101 containing multiple tubes inside, a silicone rubber balloon 102 attached to the insertion end of the catheter body 101, a silicone rubber urination funnel 103 attached to the end opposite the insertion end of the catheter body 101 and to which a urine bag 200 is connected, and a silicone rubber balloon funnel 104 attached to the end opposite the insertion end of the catheter body 101 so as to branch off from the urination funnel 103 and to which a syringe 300 is connected.

[0004] A side hole 105 is formed at the insertion end of the catheter body 101, closer to the tip than the balloon 102, and this side hole 105 communicates with a urination tube housed in the catheter body 101. Urine in the bladder is collected through the side hole 105 and the urination tube in a urination bag 200 connected to the urination funnel 103.

[0005] In addition, inflation water is injected into the balloon 102 from the syringe 300 connected to the balloon funnel 104 through the inflation water tube inside the catheter body 101, causing the balloon 102 to expand.The inflation of the balloon 102 at a position close to the urethra inside the bladder prevents the catheter body 101 from coming out, allowing the bladder balloon catheter 100 to be retained in the bladder.

[0006] The bladder balloon catheter 100 shown in Figure 11 is an integrated catheter body 101, balloon 102, urination funnel 103, and balloon funnel 104 that is sterilized with a well-known sterilizing agent such as ethylene oxide gas (hereinafter referred to as EOG) and then stored in a sealed sterilization bag.

[0007] This type of bladder balloon catheter 100 is used for continuous urinary catheterization in both female and male patients, but when inserting the bladder balloon catheter 100 into the patient's bladder, the tip of the bladder balloon catheter 100 must be inserted and left in place inside the patient's urethra and bladder while keeping the bladder balloon catheter 100 in a sterile state.In this case, if the bladder balloon catheter 100 is inserted too far, the inner wall of the bladder may be damaged, and if it is not inserted enough, urine may leak out without passing through the bladder balloon catheter 100, so the insertion procedure must be carried out carefully and quickly, taking into consideration the burden on the patient.

[0008] The procedure for inserting the catheter into a female patient is briefly explained as follows: The operator disinfects his or her hands, puts on sterile gloves, opens the sterile bag, removes the bladder balloon catheter 100, connects the syringe 300 containing sterile distilled water as inflation water to the balloon funnel 104, and connects the urine bag 200 to the urination funnel 103.

[0009] Then, for example, the position of the external urethral opening is confirmed with the left hand, and the external urethral opening is held in a position that makes it easy to insert the tip of the catheter body 101 of the bladder balloon catheter 100. As shown in Figures 12 and 13, the tip of the catheter body 101 is inserted into the urethra by pinching it with forceps 400 held in the right hand at a position 5 to 10 cm from the tip of the insertion side of the catheter body 101.

[0010] As the insertion of the catheter main body 101 progresses and the tip reaches the inside of the bladder B, as shown in Figure 13, urine in the bladder B flows through the bladder balloon catheter 100 into the urination bag 200, and when urine begins to collect in the urination bag 200, it is determined that the tip of the catheter main body 101 has reached the bladder B. Once urine begins to collect in the urination bag 200, the catheter main body 101 continues to be inserted another 2 to 3 cm deeper.

[0011] At this time, when urine flows into the urine drainage bag 200, the balloon 102 is still inside the urethra N and has not yet reached the inside of the bladder B. Therefore, if the balloon 102 is inflated in this state, the balloon 102 may expand inside the urethra N and damage the urethra N. Therefore, it is common to insert the catheter main body 101 another 2 to 3 cm deeper after urine begins to collect in the urine drainage bag 200.

[0012] Then, once the balloon 102 has been inserted into the bladder B from the urethra N, the hand that was supporting the external urethral meatus is used to hold the forceps 400 and support the catheter main body 101, and the syringe 300 is used with the hand that was holding the forceps 400 to perform an injection operation, injecting the inflation water in the syringe 300 into the balloon 102 to inflate it, and after confirming that the balloon 102 will not come out, the catheter main body 101 is inserted 1 to 2 cm deep and secured with tape or the like to complete the insertion procedure. If the balloon 102 remains in contact with the outlet of the bladder B, the patient will feel the urge to urinate or experience discomfort due to pressure, so it is common to insert the catheter main body 101 a further 1 to 2 cm to prevent this. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-043010 Summary of the Invention [Problem to be solved by the invention]

[0014] However, when inserting the catheter body 101 using the forceps 400, it is possible to know that the tip of the catheter body 101 has reached the bladder B when urine begins to collect in the urine bag 200, but it becomes difficult to know how far the catheter body 101 has actually been inserted or how far it should be inserted in the future, which presents a problem of making it difficult to reliably insert the catheter body 101. Furthermore, when inserting the catheter body 010 using the forceps 400, the catheter body 101 is supported while being clamped by the forceps 400, so the forceps 400 often clamp too tightly, and if the forceps 400 clamp too tightly in this way, the tube for inflation water inside the catheter body 101 is compressed, making it impossible to inject inflation water from the syringe 300.

[0015] Specifically, if a person is right-handed, it is more convenient for the operator to hold the forceps 400 with the right hand, which is the dominant hand, and insert the catheter body 101 in order to improve work efficiency, so the operator supports the urethral meatus with the left hand, which is the non-dominant hand, and when performing the injection operation of the syringe 300, the operator changes the forceps 40 to the left hand and performs the injection operation of the syringe 300 with the right hand. At this time, the left hand that has been supporting the urethral meatus is not clean, and when changing the forceps 400 with the left hand, which is the non-dominant hand, the operator tends to apply strong pressure to the catheter body 101. In many cases, the operator does not realize that the strong pressure on the catheter body 101 by the forceps 400 is the reason why the expansion water of the syringe 300 cannot be injected due to this pressure, and while hastily changing the forceps 400 to the right hand, the operator may touch the catheter body 101 with the dirty left hand, causing a hygiene problem and preventing the insertion operation from being performed smoothly. Furthermore, pinching the catheter body 101 tightly with the forceps 400 may result in the catheter body 101 being damaged, and in the case of male patients, the urethra is long, so there is a risk that the patient's urethra may be damaged when the catheter body 101 is inserted.

[0016] It is also conceivable to perform the above-described insertion operation with a hand wearing sterile gloves, without using forceps 400, but because the left hand that has been supporting the urethral meatus is not clean as described above, there is a risk of causing a hygiene problem by switching the catheter body 101 to another hand and supporting it with the unclean left hand. To avoid this, it is conceivable to first disinfect the unclean left hand and then switch the catheter body 101, or to continue supporting the catheter body 101 with the right hand without switching hands and perform the injection operation of the syringe 300 with the left hand that has been supporting the urethral meatus. However, since the injection operation of the syringe 300 is performed after supporting the urethral meatus with the non-dominant left hand, it is very difficult to perform the injection operation of the syringe 300 because the left hand is not the dominant hand, and there is a risk of reducing work efficiency.

[0017] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to enable the insertion of a bladder balloon catheter to be performed smoothly and hygienically. [Means for solving the problem]

[0018] In order to achieve the above-mentioned object, the insertion aid for a bladder balloon catheter of the present invention is an insertion aid used when inserting the insertion end of a bladder balloon catheter into the urethra and bladder, and after completion of insertion, injecting balloon inflation water into the insertion end of the bladder balloon catheter using a syringe connected to a balloon funnel at the end opposite the insertion end of the bladder balloon catheter to inflate the balloon. The insertion aid comprises an attachment part that is detachably attached to a position a specified insertion length from the tip of the insertion end of the bladder balloon catheter, and a grip part that is continuous with the attachment part and extends in a direction perpendicular to the longitudinal direction of the bladder balloon catheter, and the attachment part has an adhesive surface that releasably adheres to the outer surface of the bladder balloon catheter to prevent slippage when the grip part is held to insert the bladder balloon catheter.

[0019] Furthermore, it is desirable that the mounting portion and the gripping portion are resistant to the sterilizing agent of the bladder balloon catheter, and that the adhesive surface is made of a material that does not leave any adhesive residue on the outer surface of the bladder balloon catheter when the mounting portion is removed.

[0020] Here, silicone rubber is preferred as the material for the adhesive surface, and medical silicone grade rubber for medical use is most preferred.

[0021] The gripping portion may also include a fixing portion for fixing the end portion opposite the insertion side of the bladder balloon catheter.

[0022] In addition, the mounting portion and the gripping portion may be integrally formed from a thin resin plate that can be bent at the center, an adhesive layer may be laminated on one surface of the mounting portion and the gripping portion, the mounting portion may be formed by folding the center of the thin plate, and the adhesive surface may be formed by the adhesive layer on the one surface of the mounting portion, and the gripping portion may be formed by bonding both ends of the folded thin plate together with the adhesive layer.

[0023] The mounting portion may have an arc-shaped cross section that conforms to the outer peripheral surface of the bladder balloon catheter, and the grip portion may extend from one end of the mounting portion.

[0024] The mounting portion may also have a cylindrical shape with an axial split formed therein, and the split portion may be widened to be mounted on the outer peripheral surface of the bladder balloon catheter.

[0025] Furthermore, it is desirable that the insertion aid be sterilized together with the bladder balloon catheter and sealed in a sealed container, with the mounting portion attached to a predetermined position on the bladder balloon catheter. [Effects of the Invention]

[0026] According to the present invention, it is possible to prevent the bladder balloon catheter from being compressed when injecting inflation water from a syringe into the balloon, making it impossible to inject inflation water, and it is possible to support the bladder balloon catheter by grasping the handle rather than directly supporting it with dirty hands, allowing the insertion of the bladder balloon catheter to be performed smoothly and hygienically.

[0027] In addition, by attaching the bladder balloon catheter at a specified insertion length from the tip of the insertion end, it is possible to prevent the bladder from being damaged by inserting the bladder balloon catheter too far, or urine leakage from being caused by inserting the bladder balloon catheter too little.

[0028] Furthermore, since the adhesive surface of the attachment part is removably attached to the bladder balloon catheter, the attachment part can be attached and removed freely. Therefore, the attachment part can be removed, washed, and then attached again, making it possible to use the insertion aid repeatedly. [Brief explanation of the drawings]

[0030] (First embodiment) A first embodiment of an insertion aid for a bladder balloon catheter according to the present invention will be described in detail with reference to Figures 1 to 8. This insertion aid is suitable for inserting a bladder balloon catheter into a female patient, and the following description will be given of its use in a female patient.

[0031] In Figure 1, reference numeral 1 denotes a bladder balloon catheter having basically the same configuration as that shown in Figure 11, and comprises a long, flexible silicone rubber catheter body 11 containing multiple tubes inside, a silicone rubber balloon 12 attached to the insertion end of the catheter body 11, a silicone rubber urination funnel 103 attached to the end opposite the insertion end of the catheter body 11 and to which a urine bag 2 is connected, and a silicone rubber balloon funnel 14 attached to the end opposite the insertion end of the catheter body 11 so as to branch off from the urination funnel 13 and to which a syringe 3 is connected as indicated by the arrow in Figure 1.

[0032] Furthermore, a plurality of side holes 15 are formed at the insertion end of the catheter body 11, closer to the tip than the balloon 12, and the side holes 15 communicate with a urination tube housed in the catheter body 11. Urine in the bladder is collected through the side holes 15 and the urination tube in a urination bag 2 connected to the urination funnel 13.

[0033] Furthermore, inflation water is injected into the balloon 12 from the syringe 3 connected to the balloon funnel 14 through the inflation water tube in the catheter body 11, causing the balloon 12 to inflate, and the inflation of the balloon 12 at a position in the bladder close to the urethra prevents the catheter body 11 from coming out, and the bladder balloon catheter 1 is retained in the bladder. At this time, a one-way valve is built into the balloon funnel 14, and the action of this one-way valve prevents the inflation water from flowing back from the balloon 12 even when the syringe 3 is removed.

[0034] As shown in FIG. 1, an insertion aid 5 is provided to assist in the insertion of the bladder balloon catheter 1. This insertion aid 5 comprises a thin resin plate 51 that can be bent at the center as shown in FIGS. 3 and 4, with an adhesive layer 52 laminated on one side thereof. As shown by the two-dot chain line in FIG. 4, the center of the thin plate 51 is bent to form a substantially cylindrical mounting portion 53, and the adhesive layer 52 on one side of the mounting portion 53 forms an adhesive surface 52a. Both ends of the bent thin plate 51 are bonded together by the adhesive layer 52 to form a gripping portion 54.

[0035] In this way, an adhesive layer 52 is laminated on one surface of a thin resin plate 51, and the thin plate 51 is folded so that the bladder balloon catheter 1 is sandwiched between the center of the thin plate 51, thereby forming an attachment portion 53. The adhesive layer 52 on one surface of the attachment portion 53 can be adhered to the outer surface of the bladder balloon catheter 1 as the adhesive surface 52a, thereby attaching the attachment portion 53, and the two ends of the folded thin plate 51 can be bonded together with the adhesive layer 52 to form a gripping portion 54.

[0036] Here, the thin plate 51 may be made of a flexible thermoplastic such as polycarbonate, polyethylene, or polypropylene, and the adhesive layer 52 may be made of silicone rubber, most preferably medical silicone grade rubber for medical use. In short, any material may be used as long as it is adhesive and resistant to well-known sterilizing agents such as EOG (ethylene oxide gas), and does not leave any adhesive residue on the outer surface of the catheter body 11 of the bladder balloon catheter 1 when the attachment portion 53 is removed, and can be repeatedly attached and detached.

[0037] The adhesive layer 52 can be formed by adhering one surface of the thin plate 51 with silicone rubber, and most preferably medical silicone grade rubber for medical use.

[0038] As shown in Figure 3, the insertion assist device 5 is preferably attached at a specified insertion length L from the insertion tip of the catheter main body 11. This specified insertion length L can be set based on a verified value (length) obtained by previously verifying how far the catheter main body 11 needs to be inserted into the urethra so that the balloon 12 reaches the inside of the bladder and does not come into contact with the bladder outlet even when the balloon 12 is inflated at that position. Here, the insertion length L can be set to 6 to 7 cm, or may be set to 10 cm as a safety measure to more reliably prevent inflation of the balloon 12 inside the urethra.

[0039] 1 to 3, the gripping portion 54 is provided with hook-shaped fixing portions 55 for fixing the insertion side and opposite end of the catheter body 11 of the bladder balloon catheter 1, and as shown in Fig. 8, by fixing the insertion side and opposite end of the bladder balloon catheter 1 connected to the syringe 3 and the urine bag 2 to the fixing portions beforehand when inserting the bladder balloon catheter 1, the insertion operation and the subsequent injection operation of the syringe 3 can be performed near the gripping portion 54. Furthermore, through holes 56 are formed at both ends of the thin plate 51, and an external hook or the like can be passed through the through holes 56 to hang the insertion aid 5.

[0040] As shown in Figure 2, the bladder balloon catheter 1 is an integrated unit of the catheter body 11, balloon 10, urination funnel 13, and balloon funnel 14, and the insertion aid 5 is attached to the catheter body 11. After being sterilized with a sterilizing agent such as EOG, the bladder balloon catheter 1 is housed in a sealed state in a rectangular sterilization bag 7, for example, with a transparent periphery sealed (cross-hatched portion in Figure 2). Here, the sterilization bag 7 corresponds to the "sealed container" in this invention, but the sealed container is not limited to such a sterilization bag.

[0041] Next, the procedure for inserting the bladder balloon catheter 1 into the urethra N and the bladder B using the insertion assisting device 5 will be described with reference to FIGS.

[0042] The bladder balloon catheter 1 shown in Figure 1, like that shown in Figure 11, is used for continuous urinary catheterization of a female patient. The operator disinfects his or her hands, puts on sterile gloves, opens the sterile bag 7, removes the bladder balloon catheter 1, connects the syringe 3 containing sterile distilled water as inflation water to the balloon funnel 14, and connects the urine bag 2 to the urination funnel 13.

[0043] Then, for example, the operator uses his / her non-dominant left hand to confirm the position of the external urethral meatus and hold the external urethral meatus in a position that makes it easy to insert the tip of the catheter body 11 of the bladder balloon catheter 1, and as shown in Figure 5, holds the gripping portion 54 of the insertion aid 5 with his / her dominant right hand and inserts the insertion side tip of the catheter body 11 into the urethra N. At this time, it is desirable to place the urine bag 2 connected to the urination funnel 13 and the syringe 3 connected to the balloon funnel 14 in a position where they will not get in the way on the bed on which the patient is lying.

[0044] As the insertion of the catheter body 11 progresses and the tip reaches the inside of the bladder B, urine in the bladder B flows into the urination bag 2 through the bladder balloon catheter 1, allowing the operator to confirm that urine has begun to collect in the urination bag 2 and to grasp that the tip of the catheter body 11 has reached the bladder B.

[0045] At this time, when it is confirmed that the tip of the catheter main body 11 has reached the bladder B, the end face of the gripping portion 54 of the insertion aid 5 is still about 2 to 3 cm away from the external urethral meatus, and the catheter main body 11 can be inserted further, so insertion of the catheter main body 11 continues until the end face of the gripping portion 54 touches the external urethral meatus.

[0046] 6, when the catheter main body 11 is inserted until the end face of the gripping portion 54 touches the external urethral meatus, it can be determined that the balloon 12 has passed through the urethra N and reached the exit of the bladder B. The operator then uses the left hand that was previously supporting the external urethral meatus to shift gripping portion 54 of the insertion aid 5 to support the catheter main body 11, and as shown in FIG. 7, the operator uses the right hand that was previously holding gripping portion 54 to perform the injection operation, injecting the inflation water from the syringe 3 into the balloon 12 to inflate the balloon 12. At this time, the left hand that has shifted gripping portion 54 is not clean because it was touching the external urethral meatus, but because it does not directly touch the bladder balloon catheter 1, the cleanliness of the bladder balloon catheter 1 can be maintained, and the operator's dominant right hand can be used to easily perform the injection operation with the syringe 3.

[0047] Thereafter, the operator fixes the catheter main body 11 with tape or the like, peels off both ends of the gripping portion 54 of the insertion assisting device 5 that has been stuck together, and peels the adhesive surface of the attachment portion 53 from the outer peripheral surface of the catheter main body 11 to remove the insertion assisting device 5 from the bladder balloon catheter 1, thereby completing the insertion procedure. Note that the order of fixing the catheter main body 11 with tape and removing the insertion assisting device 5 does not matter.

[0048] As shown in Figure 8, the insertion side and opposite end of the bladder balloon catheter 1 can be fixed to the hook-shaped fixing portion 55 provided on the gripping portion 54. Therefore, by fixing the insertion side and opposite end of the bladder balloon catheter 1, which has the syringe 3 and urine bag 2 connected to it, to the fixing portion beforehand when inserting the bladder balloon catheter 1, the insertion operation and the subsequent injection operation of the syringe 3 can be easily performed near the hand, near the gripping portion 54.

[0049] Therefore, according to the first embodiment described above, by adhering the adhesive surface 52a of the attachment part 53 to the outer peripheral surface of the bladder balloon catheter 1, the attachment part 53 can be attached without slipping to a position at the specified insertion length L from the tip of the insertion end of the bladder balloon catheter 1, and the bladder balloon catheter 1 can be inserted by grasping the grip part 54, thereby preventing the bladder balloon catheter 1 from being compressed when injecting inflation water from the syringe 3 into the balloon 12, as occurs when the catheter is supported by conventional forceps 400 (see Figures 11 to 13). At this time, because the insertion aid 5 is attached at a position at the specified insertion length L from the tip of the insertion end of the bladder balloon catheter 1, the operator knows that they only need to insert the catheter main body 11 by the insertion length L, making the insertion procedure easier.

[0050] Furthermore, with the attachment part 53 attached to the bladder balloon catheter 1 at a predetermined position, the insertion aid 5 is sterilized together with the bladder balloon catheter 1 and sealed in the sterilization bag (sealed container) 7, eliminating the need to separately disinfect and sterilize the insertion aid 5, and the insertion process can be carried out immediately after removal from the sterilization bag 7, making handling extremely easy. In addition, the bladder balloon catheter 1 is about the width of a laptop computer and two to three times as thick, making it very bulky and taking up space during insertion. However, by sealing the insertion aid 5 together in the sterilization bag (sealed container) 7, the insertion aid 5 is less bulky and easier to insert than if it were separate from the bladder balloon catheter 1, which has the advantage of making it easier to insert.

[0051] In addition, since the bladder balloon catheter 1 can be supported by grasping the grip portion 54 without directly supporting it with dirty hands, the insertion operation can be performed smoothly while maintaining the cleanliness of the bladder balloon catheter 1.

[0052] Furthermore, by attaching the attachment part 53 at a specified insertion length L from the tip of the insertion end of the bladder balloon catheter 1, it is possible to prevent the bladder from being damaged by inserting the bladder balloon catheter 1 too far, or to prevent urine leakage from being caused by inserting the bladder balloon catheter 1 too little, and even an unskilled worker can insert the bladder balloon catheter 1 to the optimal insertion amount.

[0053] Furthermore, since the adhesive surface 52a of the attachment portion 53 is removably attached to the bladder balloon catheter 1, the attachment portion 53 can be attached and removed freely. Therefore, the attachment portion 53 can be removed, washed, etc., and then attached again, thereby providing an insertion aid 5 that can be used repeatedly, which is economical.

[0054] Furthermore, the adhesive surface 52a is made of a material that does not leave any adhesive residue on the outer surface of the bladder balloon catheter 1 when the attachment portion 53 is removed. Therefore, after the bladder balloon catheter 1 has been inserted and left in place, even if the attachment portion 63 is removed from the bladder balloon catheter 1, no residue remains on the adhesive surface 52a, and the bladder balloon catheter 1 can be kept clean.

[0055] In addition, since the gripping portion 54 is provided with a hook-shaped fixing portion 55 for fixing the insertion side and the opposite end of the bladder balloon catheter 1, the insertion side and the opposite end of the bladder balloon catheter 1 can be fixed to the fixing portion 55. By fixing the insertion side and the opposite end of the bladder balloon catheter 1, which has the syringe 3 and urine bag 2 connected to it in advance, to the fixing portion 55 when inserting the bladder balloon catheter 1, the insertion of the catheter body 11 and the subsequent injection operation with the syringe 3 can be easily performed near the hand near the gripping portion 54, and the insertion of the bladder balloon catheter 1 can be performed efficiently.

[0056] Furthermore, by laminating an adhesive layer 52 on one side of thin resin plate 51 and folding thin plate 51 so as to sandwich bladder balloon catheter 1 in the center, attachment portion 53 can be formed, with adhesive layer 52 on one side of attachment portion 53 serving as adhesive surface 52a that adheres to the outer periphery of bladder balloon catheter 1 to attach attachment portion 53, and both ends of folded thin plate 51 can be bonded together with adhesive layer 52 to form grip portion 54. Even if insertion aid 5 is separate from bladder balloon catheter 1, after insertion aid 5 has been sterilized and disinfected, attachment portion 53 can be easily attached to bladder balloon catheter 1 for insertion.

[0057] The removed insertion aid 5 can also be used for other purposes. For example, when winding a long medical tube such as a patient's oxygen tube or IV tube into a loop several times, the wound tube can be bundled with this insertion aid 5 and the two ends of the gripping part 54 can be glued together to keep the tube bundled. External hooks can be passed through the through holes 56 at both ends of the gripping part 54 to hang the long medical tube out of the way.

[0058] (Second embodiment) A second embodiment of the insertion assist device for a bladder balloon catheter according to the present invention will be described in detail with reference to Figure 9. In Figure 9, the same reference numerals as in Figures 1 to 8 indicate the same or corresponding parts, and the following describes the differences between the second embodiment and the first embodiment.

[0059] As shown in Figure 9, this differs from the first embodiment in that the length of the thin resin plate 51 shown in Figure 3 is halved, mounting portion 53a is formed to have an arc-shaped cross section that fits along the outer peripheral surface of bladder balloon catheter 1, grip portion 54a extends from one end of mounting portion 53, and holding portion 54 is provided with fixing portion 55a to form insertion aid device 5a. In Figure 9, reference numeral 56a denotes a through-hole formed at the end of grip portion 54a.

[0060] Therefore, according to the second embodiment, it is possible to not only achieve the same effects as the first embodiment described above, but also to adhere the attachment portion 53a, which has an arc-shaped cross section, to the outer peripheral surface of the bladder balloon catheter 1 using its adhesive surface. Therefore, even if the insertion aid 5a is separate from the bladder balloon catheter 1, the attachment portion 53a can be easily attached to the bladder balloon catheter 1 after disinfecting and sterilizing the insertion aid 5a.

[0061] In this case, if the insertion aid 5a is configured separately from the bladder balloon catheter 1, when attaching the attachment part 53a to the catheter body 11 of the bladder balloon catheter 1, it is desirable to removably attach an indicator member 8, marked with a scale in 0.5 cm increments, to the attachment part 53a as a guide for the insertion length L, as shown in Figure 9, so that the attachment part 53a can be easily removed at a position the specified insertion length L from the insertion tip of the catheter body 11.

[0062] (Third embodiment) A third embodiment of the insertion assist device for a bladder balloon catheter according to the present invention will be described in detail with reference to Fig. 10. In Fig. 10, the same reference numerals as in Figs. 1 to 8 indicate the same or corresponding parts, and the following describes the differences between the third embodiment and the first embodiment.

[0063] As shown in Figure 10, this embodiment differs from the first embodiment in that an axial split 53b is formed in the substantially cylindrical mounting portion 53 of the first embodiment, and the insertion aid 5b is formed by widening this split 53b so that it can be attached to the outer circumferential surface of the bladder balloon catheter 1. Note that the fixing portion 55 is not shown in Figure 10. Also, in the transliteration device, it is preferable to provide the indicator member 8 shown in Figure 9 on the mounting portion 53.

[0064] Therefore, according to the third embodiment, it is not only possible to achieve the same effects as the first embodiment described above, but also possible to attach the cylindrical mounting portion 53 to the outer peripheral surface of the bladder balloon catheter 1 by widening the slit 53b of the mounting portion 53 and attaching the mounting portion 53 to the outer peripheral surface of the bladder balloon catheter 1, so that the adhesive surface 52a of the mounting portion 53 adheres to the outer peripheral surface of the bladder balloon catheter 1. Therefore, even if the insertion aid 5b is separate from the bladder balloon catheter 1, the insertion aid 5b can be disinfected and sterilized and then the mounting portion 53 can be easily attached to the bladder balloon catheter 1.

[0065] The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

[0066] For example, in the first embodiment described above, the mounting portion 53 is described as being approximately cylindrical, but the mounting portion 53 does not necessarily have to be cylindrical; it may have any shape as long as it can adhere to the outer surface of the bladder balloon catheter 1 via the adhesive surface 52a and does not slip when the bladder balloon catheter 1 is inserted.

[0067] Furthermore, in the first embodiment described above, an example was described in which the insertion aid device 5 was formed by bending the thin resin plate 51, but this is not limited to forming it by bending the thin plate 51, and it is sufficient if it has a configuration that includes an attachment portion that can be attached detachably by adhering to the outer surface of the bladder balloon catheter 1 with an adhesive surface, and a grip portion that is continuous with this attachment portion and extends in a direction perpendicular to the longitudinal direction of the bladder balloon catheter.

[0068] Furthermore, in each of the above-described embodiments, examples have been shown in which the fixing portions 55, 55a are provided on the gripping portions 54, 54a, but the fixing portions 55, 55a do not necessarily have to be provided.

[0069] The present invention can be applied to an insertion assisting device that assists in the insertion of a bladder balloon catheter. [Explanation of symbols]
