Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urinary stoma flushing and drainage device. Background Art

[0002] Anterior total cystectomy with ileal bladder replacement is the preferred treatment for muscle-invasive bladder tumors. After surgery, urine is no longer stored in the bladder, but instead flows out of the body through the ileum via a urostomy. A urostomy is an opening created on the patient's body surface to allow urine to drain out of the body. Due to the large amount of mucus secreted by the intestines after digestion and absorption, especially in the early postoperative period, intestinal mucus secretion is particularly high and requires frequent cleaning to prevent blockage of urine drainage and affect the healing of the new bladder. If the intestinal mucus is not cleaned promptly in the later stages, the stoma may become blocked, leading to rupture of the new bladder and urine leakage, which can cause serious complications.

[0003] Prolonged contact of urine and intestinal mucus with the surrounding skin can cause discomfort, such as redness, swelling, and ulcers. Cleaning can prevent these problems and reduce the frequency of replacement of equipment such as catheters and ostomy bags, extending their lifespan. Cleaning the urinary stoma also reduces discomfort and skin irritation for the patient and prevents salts and minerals in urine from crystallizing around the stoma, potentially preventing blockage.

[0004] Currently, patients can only actively clean the external surface of the stoma and the stoma bag used. Cleaning inside the stoma needs to be performed by nursing staff. The lack of professional medical equipment suitable for cleaning the inside of the stoma has increased the difficulty and complexity of nursing work to a certain extent. Domestic and foreign medical device companies do not provide professional medical equipment that can be used specifically for stoma cleaning. Domestic and foreign medical experts have not proposed improvement plans for medical equipment related to urinary stoma cleaning in professional books or journals. When encountering a situation where the stoma needs to be cleaned, nursing staff generally use other medical tubes to make and adjust a flushing device for flushing the inside of the stoma. In this case, the operating skills and experience of the nursing staff are particularly important. They need to modify and adapt various available medical devices to complete the cleaning work as safely and effectively as possible.

[0005] For example, a nurse may cut a section of a gastric tube or use a scalp needle tube to make a urinary stoma irrigation device. However, using a gastric tube or a scalp needle tube to make a urinary stoma irrigation device has the following drawbacks:

[0006] First, the depth of the tube insertion into the stoma is difficult to control. If the tube is inserted too deeply, it may damage the neobladder, causing serious problems such as bleeding and perforation, and may also spread infection. Conversely, if the tube is inserted too shallowly, the irrigation solution will not fully reach the area requiring cleaning, effectively removing secretions and bacteria, and thus failing to achieve the desired irrigation effect. Determining the appropriate insertion depth generally requires consideration of multiple factors: First, the patient's specific condition and stoma structure must be observed. Urethra length, stoma location, and morphology may vary between patients, and the nursing staff will make an initial assessment based on these factors. Second, the depth needs to be adjusted based on feedback from the procedure. During insertion, the nursing staff should closely observe the patient's response. Significant pain, discomfort, or resistance may indicate an inappropriate depth. Third, the flow of the irrigation solution should be monitored. If the irrigation solution flows smoothly and effectively cleans the stoma and surrounding area without reflux or blockage, the depth is generally considered appropriate. Fourth, the nursing staff relies on their experience. Urostoma irrigation is a specialized and risky procedure and should be performed under the supervision of a professional or professional nurse. However, these methods still have certain subjectivity and uncertainty.

[0007] Secondly, there are also differences in the cutting and adjustment of the tube body of the flushing device. The cutting of the tube body of the urinary stoma flushing device is usually determined according to the patient's specific situation and clinical needs. If the stoma is located higher or deeper, or there are individual differences in the patient's urethra length and body structure, the flushing tube may need to be cut to ensure that it can accurately reach the appropriate position and function. The method and degree of cutting will vary, such as trimming the length of the tube body, adjusting the diameter of the tube, or changing the shape of the tube head. However, sharp cuts can easily damage the stoma surface, and the accuracy and rationality of such cutting depends on the experience and judgment of the nursing staff. If handled improperly, it may affect the flushing effect and patient comfort.

[0008] Finally, other drawbacks include uneven distribution or inappropriate pore size of the irrigation holes in homemade tubes, making it difficult to evenly and effectively irrigate different areas of the stoma. It also makes it difficult to control irrigation pressure, increasing patient discomfort and injury risks. Homemade tubes also lack professional interface designs, and the end of the tube does not connect tightly to irrigation devices such as syringes, making it prone to leakage and other problems, affecting smooth operation.

[0009] The current existing technology focuses on improving ostomy bags, completely ignoring the need for flushing inside the stoma. For example, CN217138820U discloses a device for flushing and draining exudate from a wound stoma, comprising a drainage tube, a retaining ring fixedly connected to one end of the drainage tube, an anti-seepage ring fixedly connected to the top of the retaining ring, a drainage gauze provided inside the retaining ring, a flushing tube fixedly connected to the bottom of the retaining ring, a one-way valve provided on the surface of the flushing tube, a flushing box fixedly connected to the end of the flushing tube, a water pump provided inside the flushing box, and a fixed connection between the water pump output end and the flushing tube, a liquid addition tube fixedly connected to the top of the flushing box, a drainage bag fixedly connected to the bottom of the drainage tube, and a first control valve provided on the surface of the drainage bag. This flushing and drainage device is used for flushing and draining wounds of postoperative patients and cannot be used for flushing the stoma of patients with urinary stomas.

[0010] For another example, CN214859602U discloses a novel wound negative pressure suction tube with scales, comprising a suction tube and an irrigation tube, wherein the front sections of the suction tube and irrigation tube are glued together, the rear sections of the suction tube and irrigation tube are separated from each other, at least three small holes are provided at the front end of the suction tube, a suction hole is provided on the front end wall of the suction tube, a negative pressure connector is provided at the end of the suction tube, scales are provided along the length of the front end tube body of the suction tube, an irrigation port is provided at the front end of the irrigation tube, and an irrigation connector with a plug is provided at the end of the irrigation tube. When this suction tube device is used for stoma irrigation, the double tube setting at the front end increases the difficulty of entering the stoma, and the irrigation liquid flows into a single location, making it difficult to irrigate various locations within the stoma.

[0011] As described above, the present invention hopes to provide a professional drainage and flushing device that can facilitate nursing staff to implement urinary stoma flushing, facilitate unified operation steps for internal flushing of the urinary stoma, and reduce the dependence of urinary stoma flushing on the nursing experience of the nursing staff.

[0012] In addition, on the one hand, due to differences in understanding among those skilled in the art; on the other hand, because the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the utility model does not have the characteristics of these prior arts. On the contrary, the utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0013] Currently, there is a lack of specialized medical equipment suitable for internal stoma cleaning. Nurses generally use other medical tubes to create and modify custom flushing devices for urinary stomas. For example, nurses cut a section of a gastric tube or use a scalp needle to create a urinary stoma flushing device. However, these homemade urinary stoma flushing devices have the following drawbacks:

[0014] First, the depth of the tube inserted into the stoma is difficult to control. Determining the appropriate insertion depth typically requires consideration of multiple factors: First, the patient's specific condition and stoma structure. Second, adjustments need to be made based on feedback during operation. Third, the flow of irrigation fluid into and out of the stoma must be monitored. Fourth, the experience of the professional nurse is crucial.

[0015] Secondly, there are also differences in the cutting and adjustment of the irrigation device tubing. The cutting of the urinary stoma irrigation device tubing is generally determined by the patient's specific condition and clinical needs. The method and degree of cutting vary, and the accuracy and rationality of this cutting depend on the experience and judgment of the nursing staff. If handled improperly, it may affect the irrigation effect and patient comfort.

[0016] Finally, other drawbacks include uneven distribution or inappropriate pore size of the irrigation holes in homemade tubes, making it difficult to evenly and effectively irrigate different areas of the stoma. It also makes it difficult to control irrigation pressure, increasing patient discomfort and injury risks. Homemade tubes also lack professional interface designs, and the end of the tube does not connect tightly to irrigation devices such as syringes, making it prone to leakage and other problems, affecting smooth operation.

[0017] To address the shortcomings of the prior art, the present invention provides a urinary stoma irrigation and drainage device, comprising an irrigation tube, the irrigation tube comprising a tube body and a connector connected to a first end of the tube body; the tube body is provided with a first scale line for indicating the depth of entry into the stoma; the tube body is also provided with a plurality of holes; the holes are distributed non-unidirectionally along the tube body starting from the second end of the tube body, and the connector includes at least two connecting cavities of different apertures. By providing the first scale line on the irrigation tube, the depth of entry into the stoma can be effectively indicated, improving the accuracy and safety of caregivers when performing urinary stoma irrigation, thereby reducing potential injury risks. The hole design allows for even distribution of liquid, optimizes the irrigation effect, and ensures cleanliness within the stoma.

[0018] According to a preferred embodiment, the device also includes a guidewire assembly comprising a guidewire body and a handle. The guidewire body is inserted into the tube body or the sidewall of the tube body through at least one connecting lumen of the connector to guide the tube into a predetermined position within the stoma. The handle is connected to the connecting lumen to secure the position of the guidewire body. The design of the guidewire assembly precisely guides the irrigation tube into the predetermined position within the stoma, improving operational accuracy. This guiding mechanism helps reduce operational difficulty, enabling caregivers to perform irrigation more effectively while also reducing pain and discomfort for patients.

[0019] According to a preferred embodiment, the tube body is provided with several spare holes, arranged in the form of rupturable hole impressions. When needed, the spare holes can be broken open by following the hole impressions to form a usable hole. By providing rupturable spare holes, caregivers can flexibly adjust the number and distribution of holes in the irrigation tube as needed, enhancing the adaptability and flexibility of the irrigation tube. This design can meet clinical needs in different situations and improve the efficiency of the irrigation tube.

[0020] According to a preferred embodiment, each connection cavity of the connector is equipped with a temperature-sensitive patch that changes color according to a temperature range; alternatively, the connector is a temperature-sensitive connector that changes color according to temperature. The design of the temperature-sensitive patch or temperature-sensitive material installed on the connector can monitor temperature changes in real time, prevent potential complications caused by improper flushing fluid temperature, and improve nursing safety.

[0021] According to a preferred embodiment, the guide wire body of the guide wire member is provided with a second scale mark, and when the guide wire member is inserted into the tube body or the side wall of the tube body, the second scale mark is used to prompt the depth of insertion of the guide wire member. The second scale mark helps the nursing staff to control the depth of insertion, ensuring the accuracy and safety of the operation. When performing the flushing operation, the guide wire member not only plays a supporting role in the flushing tube, but also may reduce friction and improve lubricity due to its special design, such as surface coating (such as hydrophilic coating or hydrophobic coating), thereby assisting the flushing process. In addition, the material properties of the guide wire member, such as flexibility and controllability, enable it to pass through the twisted segment or narrow segment smoothly in the stoma, reducing damage to the surrounding tissues.

[0022] According to a preferred embodiment, the surface of the tube is provided with a hydrophilic coating and / or an antimicrobial coating to reduce damage to the stoma surface and reduce friction, thereby improving patient comfort and safety. Furthermore, the application of an antimicrobial coating can effectively prevent infection and reduce the risk of postoperative complications.

[0023] According to a preferred embodiment, the multiple holes in the tube are arranged with decreasing diameters from the second end to the first end, so that the flushing pressures at each hole in the tube are similar. This design improves the flushing effect of the flushing tube, effectively cleaning the stoma and avoiding localized over- or under-flushing.

[0024] According to a preferred embodiment, at least two first scale lines are provided on the tube body, with portions of the scale lines displayed in different colors to indicate abnormal depth ranges. The color-coded first scale lines on the tube body provide a visual reminder to caregivers regarding abnormal depth ranges. This visual reminder enhances operational convenience for caregivers, helps promptly identify potential risks, and ensures the safety and accuracy of the flushing process.

[0025] According to a preferred embodiment, each connecting cavity on the connector is provided with a first end cap and a second end cap. The first end cap is provided with a first injection hole, and the second end cap is provided with a second injection hole. The first and second injection holes have different apertures to accommodate injection assemblies with different apertures. This design makes it easier for caregivers to select the appropriate injection tool during use and reduces the complexity of injection assembly configuration.

[0026] According to a preferred embodiment, at least two connecting cavities on the connector are angled with each other, and the first cavity of the first connecting cavity communicates with the tube body in a substantially co-directional manner, while the second cavity of the second connecting cavity communicates with the tube body at a relative angle. This design allows the guidewire body to be directly inserted into the tube body through the first connecting cavity without bending, while the second connecting cavity is used for injecting flushing fluid, facilitating the simultaneous installation of the guidewire and the injection.

DETAILED DESCRIPTION

[0035] The following is a detailed description with reference to the accompanying drawings.

[0036] Currently, there is a lack of specialized medical equipment suitable for internal stoma cleaning. Nurses generally use other medical tubes to create and modify custom flushing devices for urinary stomas. For example, nurses cut a section of a gastric tube or use a scalp needle to create a urinary stoma flushing device. However, these homemade urinary stoma flushing devices have the following drawbacks:

[0037] First, the depth of the tube inserted into the stoma is difficult to control. Determining the appropriate insertion depth typically requires consideration of multiple factors: First, the patient's specific condition and stoma structure. Second, adjustments need to be made based on feedback during operation. Third, the flow of irrigation fluid into and out of the stoma must be monitored. Fourth, the experience of the professional nurse is crucial.

[0038] Secondly, there are also differences in the cutting and adjustment of the irrigation device tubing. The cutting of the urinary stoma irrigation device tubing is generally determined by the patient's specific condition and clinical needs. The method and degree of cutting vary, and the accuracy and rationality of this cutting depend on the experience and judgment of the nursing staff. If handled improperly, it may affect the irrigation effect and patient comfort.

[0039] Finally, other drawbacks include uneven distribution or inappropriate pore size of the irrigation holes in homemade tubes, making it difficult to evenly and effectively irrigate different areas of the stoma. It also makes it difficult to control irrigation pressure, increasing patient discomfort and injury risks. Homemade tubes also lack professional interface designs, and the end of the tube does not connect tightly to irrigation devices such as syringes, making it prone to leakage and other problems, affecting smooth operation.

[0040] like Figures 1 to 5 As shown, the utility model provides a urinary stoma irrigation and drainage device, including an irrigation tube 100. The irrigation tube 100 includes a tube body 110 and a connector 140 connected to the first end of the tube body 110. The tube body 110 and the connector 140 can be connected in an integral manner or in a split manner. When connected in a split manner, the tube body 110 and the connector 140 can be detachable or non-detachable. The tube body 110 is made of an elastic medical material, so that the tube body 110 can only cover the end of the connector 140 to form a connection relationship. Preferably, the first end of the tube body 110 can also be provided with a connecting member with a threaded structure, so that the first end of the tube body 110 is threadedly connected to the end of the connector 140.

[0041] Further preferably, the tube body 110 and the connector 140 are non-detachably connected, for example, by pre-attaching the tube body 110 and the connector 140 with a medical adhesive. This prevents leakage at the connection point. Furthermore, the non-detachable connection prevents the tube body 110 and the connector 140 from suddenly separating during stoma flushing, making the flushing process smoother, reducing the likelihood of accidents, and reducing the amount of precautions required by the caregiver during operation.

[0042] Preferably, the material of tube body 110 can be medical rubber, silicone, or other hydrophilic materials. The diameter of tube body 110 meets the specifications of medical tubes, with an outer diameter of approximately 3 to 4 mm. Preferably, the outer diameter of tube body 110 is approximately 4 mm. The inner diameter of tube body 110 is approximately 1 to 2 mm.

[0043] The tube body 110 is provided with a first scale line 120 for marking the depth of entry into the stoma. By providing the first scale line 120 on the flushing tube 100, the depth of entry into the stoma can be effectively marked, improving the accuracy and safety of the nursing staff when performing urinary stoma flushing, thereby reducing potential injury risks.

[0044] According to a preferred embodiment, at least two first scale marks 120 are provided on the tube body 110. A single first scale mark 120 is only visible at a specific angle. Therefore, the caregiver must rotate the tube body 110 to bring the first scale mark 120 into view. If the caregiver ignores the first scale mark 120, the tube body 110 may be inserted too deep into the stoma. Therefore, it is preferable to have more than one first scale mark 120.

[0045] Preferably, the cross section of the tube body 110 is used as a plane, and first scale lines 120 are provided in four mutually perpendicular directions of the circular cross section. With this design, when the tube body 110 is non-transparent, the caregiver can see the first scale lines 120 regardless of the angle from which the caregiver observes the tube body 110, without having to rotate the tube body 110 to find the first scale lines 120.

[0046] Preferably, a portion of the scale marks on the first scale line 120 are displayed in different colors to indicate abnormal depth ranges. The color-coded first scale lines 120 on the tube body 110 provide a visual reminder to caregivers regarding abnormal depth ranges. This visual reminder enhances operational convenience for caregivers, helping them promptly identify potential risks and ensuring the safety and accuracy of the flushing process.

[0047] Preferably, the total length of the first scale lines 120 ranges from 15 to 20 cm. Further preferably, the total length of the first scale lines 120 ranges from 20 cm. The zero mark on the first scale line 120 begins at the second end of the tube body 110. Insertion of the tube body 110 beyond 15 cm into the stoma is considered deep insertion. Therefore, within the range of 15 to 20 cm, the first scale lines 120 are printed and displayed in a noticeable color. For example, within the range of 15 to 20 cm, the first scale line 120 may be displayed in a color that is not easily overlooked, such as red or orange.

[0048] like Figure 5 As shown, the tube body 110 is further provided with a plurality of holes 130. The hole 130 has a diameter ranging from 0.5 to 2 mm. The holes 130 are used to evenly distribute the liquid, optimize the flushing effect, and ensure the cleanliness of the stoma.

[0049] Preferably, the holes 130 are distributed non-unidirectionally along the tube body 110, starting from the second end. The holes 130 serve to deliver irrigation fluid from different locations, allowing all locations within the stoma to be irrigated, thereby improving the cleanliness of the irrigation. The holes 130 can be arranged in multiple rows along the axial direction of the tube body 110, and arranged in rows in different circumferential directions. Preferably, the holes 130 have the same diameter, and the holes 130 in the same row are evenly distributed. This allows irrigation fluid to reach different depths within the stoma.

[0050] A drawback of uniformly distributing the holes 130 is that the irrigation pressure of the irrigating liquid in each hole 130 varies at different depths within the stoma. As the irrigating liquid flows from the first end of the tube body 110 toward the distal end, the pressure gradually decreases due to frictional losses. For holes 130 with insufficient irrigation pressure, the corresponding areas within the stoma will not be thoroughly irrigated. To compensate for the insufficient irrigation pressure caused by the decreasing pressure, the spacing between the holes 130 should decrease with increasing distance from the first end of the tube body 110. As a result, the spacing between the holes 130 near the first end of the tube body 110 is larger, while the spacing between the holes farther from the first end is smaller. Therefore, the holes 130 on the tube body 110 are arranged with increasing spacing from the second end to the first end. By adjusting the spacing, the irrigating liquid is evenly distributed at different depths within the stoma, ensuring that the irrigation pressures of each hole 130 in the tube body 110 are similar. This design improves the uniformity of the irrigation effect of the irrigation tube 100, effectively cleaning the stoma and avoiding localized over- or under-irrigation.

[0051] Preferably, the holes 130 may also be randomly arranged on the tube body 110 to prevent the flushing liquid from forming vortices in the tube, thereby improving the flushing efficiency.

[0052] Preferably, the holes 130 may also be arranged in a spiral or grid shape on the tube body 110 to enhance the structural stability and flushing effect of the tube body 110 .

[0053] like Figure 5 As shown, the tubular body 110 is provided with a plurality of spare holes 131. The spare holes 131 are provided in the form of breakable hole impressions. When necessary, the spare holes 131 form usable holes 130 in the form of breaking the tubular body 110 according to the hole impressions.

[0054] For example, a number of spare holes 131 can be set between the pre-set holes 130, or in the area between the hole distribution area and the first end of the tube body 110. The hole imprint is pre-set on the tube body 110 and is pressed to a thinner imprint. Since the hole imprint of the spare hole 131 is not a crack, it does not affect the drainage effect of the flushing liquid of the tube body 110 when it is not broken, and there will be no leakage. If the hole imprint is not set, the nursing staff will randomly cut to form irregular holes when the number of holes 130 needs to be increased. Irregular holes may cause insufficient flushing pressure, or even the flushing liquid cannot be flushed out, and can only seep out and fail to achieve a flushing effect. When the nursing staff needs to increase the number of holes 130, the nursing staff will use a tool to break the hole imprint to form regularly shaped holes 130. The flushing pressure generated by the flushing liquid of the regularly shaped holes 130 will be sufficient, and the flushing cleanliness will be high.

[0055] Therefore, by providing the rupturable spare holes 131, the nurse can flexibly adjust the number and distribution of holes in the irrigation tube 100 as needed, thereby enhancing the adaptability and flexibility of the irrigation tube 100. This design can meet clinical needs in different situations and improve the efficiency of the use of the irrigation tube 100.

[0056] like Figures 1 to 4 As shown, the connector 140 includes at least two connecting cavities with different pore diameters. According to a preferred embodiment, an angle is formed between the at least two connecting cavities on the connector 140, and the first cavity of the first connecting cavity 141 is connected to the tube body 110 in a manner that is approximately in the same direction, and the second cavity of the second connecting cavity 142 is connected to the tube body 110 in a relatively inclined manner.

[0057] like Figures 1 to 4 As shown, when the tube body 110 is placed vertically, the first connecting cavity 141 on the connecting member 140 is also vertical in the connected state. The second connecting cavity 142 is arranged obliquely.

[0058] The angle between the first connecting cavity 141 and the second connecting cavity 142 can be in the range of 20 to 60 degrees. Preferably, the angle between the first connecting cavity 141 and the second connecting cavity 142 is 30 to 45 degrees. This design reduces the resistance of the flushing liquid entering the flushing tube 100.

[0059] Providing two or more connecting cavities allows the connecting cavities to accommodate a wider range of injection components. For example, an injection component is a syringe. Given the heavy workload and numerous patients, frequent syringe selection consumes significant nursing time and effort. Therefore, the provision of multiple connecting cavities in connector 140 can prevent caregivers from frequently changing injection components, saving time and improving the efficiency of stoma flushing.

[0060] like Figures 1 to 4 As shown, each connecting cavity on the connecting member 140 is provided with a first end cap 143 and a second end cap 144. A first injection hole 145 is provided on the first end cap 143. A second injection hole 146 is provided on the second end cap 144. The apertures of the first injection hole 145 and the second injection hole 146 are different to be suitable for injection assemblies with different specifications of apertures. The aperture of the first injection hole 145 is larger than the aperture of the second injection hole 146. When it is necessary to use a syringe with a smaller aperture that matches the aperture of the second injection hole 146, the first end cap 143 is buckled on the connecting cavity (the first connecting cavity 141 or the second connecting cavity 142), the second end cap 144 is buckled on the first end cap 143, and the syringe is inserted into the second injection hole 146 to realize the injection of the flushing liquid.

[0061] Obviously, the apertures of the first injection hole 145 and the second injection hole 146 are smaller than the apertures of the respective connecting cavities, and thus can be adapted for smaller-sized injection assemblies. This design allows caregivers to more conveniently select the appropriate injection tool during use, reducing the complexity of the injection assembly configuration.

[0062] Preferably, if Figures 1 to 4 As shown, the diameters of the first connecting cavity 141 and the second connecting cavity 142 are gradually changed and gradually become smaller towards the connecting end. Such a design can appropriately increase the pressure of the injected flushing liquid and avoid insufficient flushing pressure of the flushing liquid in the tube body 110.

[0063] Currently, since the medical tube body 110 is relatively soft, it is easy to deform during the process of inserting the tube body 110 into the stoma, and the nursing staff needs to spend more time to successfully insert the tube body 110. Therefore, reducing the difficulty of inserting the tube body 110 into the stoma is a problem that must be solved.

[0064] To address this issue, the urostomy irrigation and drainage device of the present invention further includes a guidewire assembly 200. The guidewire assembly 200 comprises a guidewire body 210 and a handle 220. The guidewire body 210 can be made of medical stainless steel, nickel-titanium alloy, or the like, offering excellent support, thrust, and torque control, as well as corrosion resistance. Nickel-titanium alloy is a memory metal widely used in the manufacture of the guidewire body 210 due to its excellent elasticity and ability to prevent kinking.

[0065] Preferably, the surface of the guidewire body 210 is provided with a coating material and a hydrophilic coating. For example, a polymer such as polyurethane or polytetrafluoroethylene (PTFE) is used as the coating material. These materials not only improve the tissue compatibility and blood compatibility of the guidewire body 210, but also effectively reduce the friction on the guidewire surface and improve the visibility of the operation. The hydrophilic coating is made of materials such as polyvinyl pyrrolidone (PVP) or polyacrylamide (PAM), which can attract water molecules when exposed to water, forming a layer of smooth gel-like substance on the surface of the guidewire body 210, thereby achieving a drainage and flushing effect and reducing friction, thereby improving the pushability of the guidewire body.

[0066] The handle 220 is provided at one end of the guidewire body 210. The shape of the handle 220 is not limited and can be formed into various geometric shapes as required, as long as the function of assisting in rotating or moving the guidewire body 210 can be achieved. Figure 1 The handle 220 includes a socket portion and a rotating wing. The rotating wing is a roughly rectangular sheet. Figure 6 As shown, the rotating wings of the handle 220 are circular or elliptical sheets. Preferably, the number of rotating wings can be flexibly set, not limited to Figure 1 and Figure 6 The guide wire body 210 is inserted into the tube body 110 or the side wall of the tube body 110 through at least one connecting lumen of the connector 140 to guide the tube body 110 into a predetermined position in the stoma.

[0067] Specifically, if Figure 3 As shown, the guidewire body 210 can be inserted into the tubular body 110 through at least one connecting cavity of the connector 140. There is a gap between the guidewire body 210 and the tubular body 110, so no resistance is formed to the flow of the flushing liquid.

[0068] Preferably, if Figure 1 As shown in the partial enlarged view of the guide wire body 210 in FIG, the guide wire body 210 is provided with a second scale mark 300. The second scale mark 300 can be printed on the surface of the guide wire body 210 or under a perspective hydrophilic coating in a visible manner. When the guide wire member 200 is inserted into the tubular body 110 or the side wall of the tubular body 110, the second scale mark 300 is used to prompt the depth of insertion of the guide wire member 200. The nursing staff can determine the depth of insertion of the guide wire body 210 based on the second scale mark 300 exposed outside the tubular body 110. By clearly displaying the insertion depth, the second scale mark 300 helps to prevent the guide wire body 210 from being inserted too deeply or too shallowly, thereby avoiding possible damage to the patient or instrument function failure.

[0069] In certain situations, when flushing the stoma, it may be necessary to position the guidewire body 210 to a specific location. The second scale mark 300 provides a clear reference, allowing the operator to easily position the guidewire body 210 to the desired location. During teaching and training, the second scale mark 300 on the guidewire body 210 provides an intuitive learning tool for medical students or newly trained doctors in the process of learning how to use the guidewire 200, helping them to quickly master the correct usage methods and techniques.

[0070] Preferably, if Figure 1 As shown, the diameter of the front end (insertion end) of the guidewire body 210 gradually decreases. Within a range of approximately 1 to 2 mm from the front end of the guidewire body 210, in the direction from the rear end of the guidewire body 210 (the end where the handle 220 is provided) to the front end, the diameter of the front end of the guidewire body 210 begins to decrease and forms a structure that is approximately conical, i.e., a cone-like structure. The front end of the guidewire body 210 is provided with a characteristic of gradually decreasing diameter, which can reduce the difficulty of inserting the guidewire body 210, improve controllability, and reduce tissue damage.

[0071] Preferably, the front end of the guidewire body 210 has a circular or elliptical profile to prevent the guidewire body 210 from damaging the stoma skin while guiding the tube 110 into the stoma. This design creates a conical shape at the front end of the guidewire body 210 with a smooth, curved end. Preferably, the length of the guidewire body 210 is approximately 1 cm longer than the length of the tube 110. After the guidewire body 210 is inserted into the tube 110, the conical shape at the front end of the guidewire body 210 protrudes from the tube 110 and guides the movement and insertion of the tube 110 within the stoma.

[0072] Specifically, the front end diameter of the guidewire body 210 gradually decreases to form a cone-like structure. This design can significantly reduce the difficulty of inserting the guidewire into the tube body 110, making the operation smoother and safer. The front end with a gradually decreasing diameter is more easily adapted to a tortuous or narrow stoma, thereby reducing damage and irritation to the skin of the stoma. The front end with a gradually decreasing diameter helps to enhance the tracking performance of the guidewire body 210, that is, the ability of the guidewire body 210 to move along the structure within the stoma. This design makes the guidewire body 210 more flexible when carrying the tube body 110 in the stoma, and can effectively cope with various complex special structures.

[0073] The reduced diameter of the front end of the guide wire body 210, combined with coating technology, such as a hydrophilic coating, can reduce the friction between the guide wire body 210 and the stoma skin, thereby alleviating the patient's discomfort.

[0074] Although the reduction in front diameter may affect the support force of the guidewire body 210, by optimizing the guidewire material and structural design, such as using nickel-titanium alloy and reinforced stainless steel, sufficient support force can be provided while maintaining flexibility. The gradually decreasing diameter design also helps to evenly transmit the pushing force, making the guidewire body 210 move more smoothly within the stoma.

[0075] like Figure 4 As shown, the first connecting cavity 141 is connected to the hole on the side wall of the tube body 110, and the guidewire body 210 can be inserted into the side wall of the tube body 110 through at least one connecting cavity of the connector 140. In this way, the guidewire body 210 is covered by the tube body 110 and is not in the channel of the tube body 110. The guidewire body 210 can harden the tube body 110 and guide the tube body 110 into the stoma without narrowing the channel in the tube body 110. Preferably, after the tube body 110 is inserted into the stoma to an appropriate depth, the guidewire body 210 can be pulled out of the tube body 110 or not. When the material of the tube body 110 is relatively soft, in order to reduce the deformation of the tube body 110 and increase the hardness of the tube body 110, the guidewire body 210 can be left in.

[0076] The handle 220 is connected to the connecting cavity to fix the position of the guide wire body 210. Preferably, a connecting buckle or threaded structure that matches the cavity opening of at least one connecting cavity on the connector 140 can be provided on the handle 220, so that the handle 220 can be connected to the connecting cavity after the guide wire body 210 enters the connecting cavity, such as the first connecting cavity 141. An angle is formed between the two connecting cavities of the connector 140, so that the guide wire body 210 can be directly inserted into the tubular body 110 through the first connecting cavity 141 without bending. The second connecting cavity 142 is used to inject flushing fluid, which is convenient for the simultaneous setting of the guide wire member 200 and the injection.

[0077] Therefore, the design of the guide wire 200 can accurately guide the irrigation tube 100 into the predetermined position of the stoma, improving the accuracy of the operation. This guiding mechanism helps to reduce the difficulty of operation, allowing caregivers to perform irrigation more effectively, while also reducing the pain and discomfort of the patient.

[0078] like Figures 1 to 4As shown, each connecting cavity of the connector 140 is provided with a temperature-sensitive patch 400 for changing color according to the temperature range. Alternatively, the connector 140 is a temperature-sensitive connector 140 that can change color according to the temperature. Preferably, the reasonable temperature range of the flushing liquid is 30 to 40°C. Inappropriate temperature will irritate the mucosa inside the stoma. Further preferably, the optimal temperature range for the flushing liquid to enter the stoma is 34 to 37°C. Therefore, the temperature-sensitive patch 400 or the temperature-sensitive connector does not change color for temperatures between 30 and 40°C, and will change color below 30°C or above 40°C. The color change of the temperature-sensitive patch 400 or the temperature-sensitive connector can remind the nursing staff that the temperature of the flushing liquid is inappropriate.

[0079] The design of the temperature-sensitive patch 400 or the temperature-sensitive material provided on the connector 140 can monitor temperature changes in real time, prevent potential complications caused by inappropriate temperature of the flushing fluid, and improve nursing safety.

[0080] Preferably, the temperature-sensitive material of the temperature-sensitive patch 400 or the temperature-sensitive connector can be a reversible thermochromic material. These materials can achieve color changes within a specific temperature range, such as -15°C to 70°C, and the color change is reversible. The temperature-sensitive material of the temperature-sensitive patch 400 or the temperature-sensitive connector can also be a temperature-changing powder, which is mainly composed of a color-changing dye, a color developer and a solvent. Within the set temperature range, the temperature-changing powder appears white or colorless. In the set low temperature range, the color-changing dye and the color developer approach each other and undergo structural changes, showing color. By adjusting the solidification temperature of the solvent, products that change color at different temperatures can be prepared.

[0081] According to a preferred embodiment, the surface of the tube body 110 is provided with a hydrophilic coating and / or an antimicrobial coating to reduce damage to the stoma surface caused by the tube body 110 and reduce friction, thereby improving patient comfort and safety. Furthermore, the application of the antimicrobial coating can effectively prevent infection and reduce the risk of postoperative complications.

[0082] According to a preferred embodiment, the surface of the tube body 110 may also be provided with a hydrophilic gradient coating. The gradient coating gradually transitions from the front end (insertion end) to the rear end (exposed end) of the tube body 110. For example, it gradually transitions from a light color (such as light blue) to a dark color (such as dark blue). This gradient helps caregivers more intuitively perceive the insertion depth. The clear contrast between the light front end and the dark rear end makes it easier to judge the insertion progress of the tube body 110.

[0083] The tube body 110 is divided into several segments, each with a gradient color change. For example, the first third changes from light blue to medium blue, the middle third changes from medium blue to dark blue, and the last third changes from dark blue to an even darker blue. This segmented gradient provides more visual reference points, helping caregivers more accurately control insertion depth. The color change of each segment serves as a cue to aid in determining and adjusting the insertion state.

[0084] These technical effects together improve the convenience, efficiency and safety of the urinary stoma irrigation and drainage device during use, ensuring a better operating experience and patient comfort.
