Description

Technical Field

[0001] The present invention relates to the technical field of medical irrigators, and in particular to an integrated vaginal irrigating and urinary catheterization device for improving the nursing efficiency before after-treatment. Background Art

[0002] Before brachytherapy for cervical cancer, vaginal irrigation and urinary catheterization are important nursing procedures. Prior art patent CN112843356A discloses a vaginal douche, comprising an irrigation assembly and an adjustment assembly. The irrigation assembly includes an irrigation core tube, an irrigation sleeve, a set of wash nozzles, and an irrigation connector. The irrigation sleeve is fixedly mounted on the outer periphery of the irrigation core tube. The top opening of the irrigation core tube is located at the top of the irrigation sleeve. The set of wash nozzles is evenly distributed on the surface of the irrigation sleeve. The wash nozzles are connected to the irrigation core tube. The irrigation connector is connected to the bottom of the irrigation core tube. The adjustment assembly includes a regulating valve, a three-way dropper, a tube plug, and a recovery airbag. The regulating valve is connected to one side below the irrigation core tube, the three-way dropper is connected to one side below the regulating valve, the tube plug is connected to one side below the three-way dropper, and the recovery airbag is connected to the outer side of the regulating valve. When in use, the flushing core tube is screwed into the flushing soft sleeve through the flushing joint for sealing, the tube is inserted to connect to the external flushing water pipeline, the upper end of the flushing soft sleeve flushes the inner wall of the vagina, and the various sub-washing nozzles connected to the openings on the surface of the flushing core tube also flush the inner wall of the vagina in all directions at the same time. The flushing water flow rate can be controlled by the regulating valve to accurately flush the patient's vagina for treatment. The syringe is inserted into the three-way dropper sealing ring to inject the medicine into the flushing water to assist in the patient's vaginal flushing treatment.

[0003] The utility model patent with prior art announcement number CN213667451U discloses a mother-and-child urinary catheter, including a first urinary catheter and a second urinary catheter. The first urinary catheter and the second urinary catheter are connected as an integral structure. The first urinary catheter has a first cavity, and the second urinary catheter has a second cavity. By adding the second cavity on the basis of the first cavity, the first cavity and the second cavity are used to simultaneously infuse drugs into the urethra, and help promote the discharge of urethral secretions, so as to achieve the effect of enhancing drainage.

[0004] However, the prior art still has the following technical problems:

[0005] 1. Cervical cancer patients require vaginal lavage and catheterization before afterloading. Traditionally, these procedures are performed in two separate, designated areas: first, vaginal lavage (which requires exposure of the vagina, placement of a speculum, and drainage of lavage fluid), followed by catheterization (which requires re-disinfection of the urethral opening and insertion of a catheter). Each procedure requires adjustments to the instrument position, disinfection area, and patient positioning, increasing the time required by medical staff. Repeated exposure of private areas can lead to muscle tension (such as urethral sphincter spasm) and increase the rate of catheterization failure (particularly in elderly patients or those with urethral mucosal edema after radiotherapy).

[0006] 2. Separate operations require the use of two independent sets of instruments (such as vaginal douches, urinary catheters, syringes, etc.). Each set of instruments must be disinfected and unpacked separately, increasing the risk of nosocomial infection (such as cross-contamination of bacteria on the surface of the instruments or the operating table). Summary of the Invention

[0007] The present invention aims to provide an integrated vaginal irrigation and catheterization device that improves the efficiency of pre-treatment care after after-treatment, so as to solve the problems of traditional operation in which vaginal irrigation and catheterization need to be completed twice. Separate operations require the use of two independent sets of instruments, resulting in low pre-care efficiency and easily causing patient tension and increasing catheterization failure rate.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A vaginal irrigation and urinary catheterization device that improves the efficiency of pre-treatment care afterward includes a urinary catheter and a vaginal irrigation tube. The urinary catheter includes a main urinary catheter and multiple branch tubes arranged at the inlet end of the main urinary catheter. The branch tubes include a water injection tube, an irrigation tube, and a liquid outlet tube. An air bag is provided at one end of the main urinary catheter away from the branch tubes. A urinary catheter water injection channel for connecting the air bag and the water injection tube is provided in the main urinary catheter. A urinary catheter irrigation channel for connecting the irrigation tube is provided in the main urinary catheter. A urinary catheter liquid outlet channel for connecting the liquid outlet tube is provided in the main urinary catheter. A liquid outlet is provided at one end of the main urinary catheter away from the liquid outlet tube.

[0010] An air bag is also provided at one end of the vaginal irrigation tube, and a vaginal water injection channel for connecting the water injection tube and the air bag is provided inside the vaginal irrigation tube; a vaginal irrigation channel connected to the irrigation tube is provided inside the vaginal irrigation tube; a vaginal liquid discharge channel connected to the liquid discharge tube is provided inside the vaginal irrigation tube, and a liquid outlet is provided at the end of the vaginal irrigation tube away from the liquid discharge tube; a three-way valve is provided at the connection between the water injection tube, the irrigation tube and the internal channel of the vaginal irrigation tube.

[0011] Preferably, as an improvement, any one of the urinary catheter outlet channel or the urinary catheter flushing channel is located on the central axis of the main urethra, and any one of the vaginal outlet channel or the vaginal flushing channel is located on the central axis of the vaginal flushing tube.

[0012] Preferably, as an improvement, when the urinary catheter outlet channel and the vaginal outlet channel are respectively located on the central axis of the main urethra and the vaginal irrigation tube, the diameter of the urinary catheter outlet channel is larger than the diameter of the urinary catheter irrigation channel; the diameter of the vaginal outlet channel is larger than the diameter of the vaginal irrigation channel.

[0013] Preferably, as an improvement, a plurality of liquid outlets are provided at one end of the main urethra away from the liquid outlet pipe, and a plurality of liquid outlets are provided at one end of the vaginal flushing tube away from the liquid outlet pipe; the tube opening at the head end of the urinary catheter flushing channel is located on the side wall of the main urethra, and the tube opening at the head end of the vaginal flushing channel is located on the side wall of the vaginal flushing tube.

[0014] Preferably, as an improvement, a chuck is provided near the air bag at the tube head of the vaginal irrigation tube.

[0015] Preferably, as an improvement, the chuck is detachably connected to the vaginal irrigation tube; a through hole is provided in the middle of the chuck, and a gap is formed on one side of the chuck; spherical protrusions are provided at intervals on the inner wall of the through hole, and inclined supports are provided at intervals in a circle on the outer wall of the chuck away from the airbag.

[0016] Preferably, as an improvement, the oblique support and the spherical protrusion are staggered.

[0017] Preferably, as an improvement, the urinary catheter is a shape memory polymer tube.

[0018] Preferably, as an improvement, the vaginal irrigation tube is a shape memory polymer tube.

[0019] Preferably, as an improvement, the urinary catheter and / or vaginal irrigation tube comprises a front section and a rear section, and the front section is a shape memory polymer tube.

[0020] Beneficial effects:

[0021] 1. This technical solution systematically solves the inefficient and high-risk problem of separate vaginal irrigation and catheterization before cervical cancer post-treatment treatment by integrating the urinary catheter and vaginal irrigation tube into an integrated design. It achieves the comprehensive benefits of improved nursing efficiency, reduced risk of nosocomial infection, and significantly improved patient comfort. It overcomes technical difficulties such as instrument cross-contamination, liquid reflux, and uncontrollable insertion depth in traditional operations, bringing safe and efficient progress to the field of gynecological tumor nursing.

[0022] 2. The urinary catheter and vaginal irrigation catheter share three branch lines: the inlet, irrigation, and outlet lines. A color-coded handle switches the three-way valve, enabling one-touch switching between bladder and vaginal irrigation. Compared to traditional separate catheterization and vaginal irrigation procedures, this system now only requires one fixed position and completes both procedures with one set of instruments, shortening patient care time. This avoids repeated exposure of the vagina and urethra, reducing patient stress and, in particular, lowering the rate of catheterization failure caused by urethral sphincter spasm in elderly patients. Eliminating the need for two separate sets of instruments, the reuse of branch lines reduces the use of disposable consumables such as speculum and catheterization bags, while also saving time and space for disinfection. Of particular note, in our hospital's post-installation treatment room, patients are exposed in the lithotomy position and the vagina is opened with a dilator for treatment. However, this integrated device allows both catheterization and vaginal irrigation to be performed in the post-installation treatment room. Post-installation treatment inherently requires the lithotomy position, so patients only need to be exposed once and the dilator only needs to be used once, significantly reducing nursing time and improving the patient experience.

[0023] 3. Install one-way valves in the urinary catheter and vaginal outlet channels. Utilizing the principle of one-way fluid conduction (e.g., silicone valves, gravity-type check structures), ensure that urine and douches can only flow outward. This prevents cross-contamination between bladder urine and vaginal douches. Even if bladder pressure fluctuates or body position changes, the one-way valves can still effectively prevent backflow.

[0024] 4. The circular balloon at the tip of the urinary catheter and the vaginal douche tube share a common infusion pipe. A three-way valve controls the switching of saline injection. The two balloons adhere to the bladder neck and the inner wall of the vaginal opening, respectively, forming a physical seal. Specifically, the urinary catheter is secured by the balloon, and a gentle outward pull confirms the seal, completely preventing the catheter from shifting due to changes in body position. The inflated vaginal balloon adheres to the vaginal opening, significantly reducing douche solution leakage and maintaining a clean environment in the treatment room.

[0025] 5. Since the vaginal irrigation tube is inserted manually, errors in the insertion length are inevitable. This technology overcomes the traditional problem by setting a chuck near the head end of the vaginal irrigation tube (5 cm away from the tube head, suitable for the vaginal length of adult women). The physical limit of the chuck avoids excessive insertion due to differences in cervical length. Even novices can fully perform the operation, greatly improving the operational tolerance rate; in particular, it protects the patient's lesion from being punctured by the tube head of the vaginal irrigation tube.

[0026] 6. In addition to being able to be integrally bonded to a fixed position on the vaginal irrigation tube, the chuck of this technology also has another unique detachable design. The chuck can be opened into a C shape and then clamped onto the vaginal irrigation tube. Combined with the scale lines on the tube wall, the user can adjust the insertion depth as needed, which is more suitable for multiple scenarios in the hospital. In addition, the inner wall of the chuck has a spherical protrusion anti-slip structure, and is combined with an oblique support that is offset from the spherical protrusion. After the chuck is against one side of the human body, even if the vaginal irrigation tube continues to move inward, the chuck can be held more tightly to the vaginal irrigation tube without slipping. The two work together more effectively to avoid over-insertion due to differences in cervical length.

[0027] 7. This technology also provides a technical solution. The urinary catheter is a shape memory polymer urinary catheter. The shape memory polymer urinary catheter maintains a hard straight shape at low temperatures (such as refrigerated state). When in use, it is taken out to facilitate precise insertion by medical staff. After being inserted into the urethra through the bladder, it can quickly return to a pre-set curved shape, fit the physiological curvature of the urethra, reduce insertion resistance, reduce the risk of mucosal damage, shorten the operation time, and improve nursing efficiency. In addition, this technology also provides a customized feasibility route. The urethra size and physiological structure of different patients are different, and universal urinary catheters may cause discomfort. Shape memory polymers can be used through 3D printing technology to customize exclusive urinary catheters based on the patient's CT or ultrasound data. The parameters such as the tube diameter, bending angle, and balloon position accurately match individual needs. The catheter is hard and slightly tough when inserted for easy operation. After insertion, it softens and fits the urethra, significantly improving wearing comfort.

[0028] 8. Traditional urinary catheters are mostly made of non-degradable materials, requiring high-temperature incineration or chemical disinfection for medical waste disposal, which can easily cause pollution. Degradable shape memory polymer urinary catheters can be triggered to rapidly degrade during subsequent disposal under specific conditions (such as temperature, humidity, or enzyme solutions), simplifying the medical waste disposal process, reducing solid waste, and aligning with the development trend of green healthcare.

[0029] In the consumables management process of large hospitals, the recycling and supervision of traditional urinary catheters requires extensive manpower and verification. Shape memory polymer urinary catheters, with their "countdown upon removal" feature, significantly simplify the management process. For example, dedicated refrigerated storage areas are set up in nursing stations. Due to their characteristics, nurses can access them immediately after use, reducing the confusion caused by traditional placement of catheters after removal. This design not only reduces management costs but also reduces potential contamination caused by excessive device transfer, significantly improving the efficiency of hospital infection prevention and control.

[0036] The following is further described in detail through specific implementation methods:

[0037] The reference numerals in the drawings of the specification include: urinary catheter 1, main urinary catheter 11, urinary catheter water injection channel 111, urinary catheter flushing channel 112, urinary catheter liquid outlet channel 113, water injection pipe 12, water injection valve 121, flushing pipe 13, liquid outlet pipe 14, vaginal flushing pipe 2, vaginal water injection channel 21, vaginal flushing channel 22, vaginal liquid outlet channel 23, airbag 3, one-way valve 4, liquid outlet 5, three-way valve 6, chuck 7, gap 71, spherical protrusion 72, oblique support 73, handle 8.

[0038] Example 1

[0039] Basically as attached Figure 1 、 2 As shown, a vaginal irrigation and urinary catheterization device that improves the efficiency of pre-treatment care afterward includes a urinary catheter 1 and a vaginal irrigation tube 2. The urinary catheter 1 includes a main urinary catheter 11 and multiple branch tubes arranged at the inlet end of the main urinary catheter 11. The branch tubes in this embodiment include an injection tube 12, an irrigation tube 13, and a liquid outlet tube 14. The urinary catheter 1 and the vaginal irrigation tube 2 are made of natural rubber, silicone rubber, or polyvinyl chloride (PVC).

[0040] The main urethra 11 has one end extending into the urethra, the tip, and the other end, the distal end. The tip of the main urethra 11 is sheathed with an annular airbag 3, which is adhesively fixed to the wall of the main urethra 11. A urinary catheter water inlet channel 111 is provided within the main urethra 11, connecting the airbag 3 with the water inlet pipe 12. A water inlet valve 121 is located at the end of the water inlet pipe 12. A syringe inserted into the valve 121 allows saline to be injected into the airbag 3, thereby inflating the airbag 3 and preventing the urinary catheter 1 from falling out of the bladder.

[0041] A urinary catheter flushing channel 112 for connecting to the flushing tube 13 is provided in the main urethra 11, and the urinary catheter flushing channel 112 is arranged along the central axis of the main urethra 11; a plurality of flushing ports are provided at one end of the main urethra 11 extending into the urethra. When it is necessary to flush the bladder, the flushing liquid (for example, normal saline) entering the flushing tube 13 enters the urethra through the urinary catheter flushing channel 112 to flush the urethra. A urinary catheter outlet channel 113 for connecting to the outlet tube 14 is provided in the main urethra 11, and an outlet 5 connected to the urinary catheter outlet channel 113 is provided on the side wall of the end of the main urethra 11 extending into the urethra. The number of the outlet ports 5 can be multiple. The flushing liquid entering the urethra is discharged through the urinary catheter outlet channel 113 and the outlet tube 14; a liquid outlet one-way valve 4 is provided on the outlet tube 14 to ensure that the liquid entering the pipeline can only flow out and not flow back, further ensuring safety.

[0042] The end of the vaginal irrigation tube 2 that extends into the vagina is the head end, and the other end is the terminal end. The head end of the vaginal irrigation tube 2 is provided with an expansion body, which in this embodiment is also an annular airbag 3. To achieve the integrated design of the urinary catheter 1 and the vaginal irrigation tube 2, the water injection pipe 12 is provided with a water injection branch port, and a three-way valve 6 is installed at the water injection branch port. The vaginal irrigation tube 2 is internally provided with a vaginal water injection channel 21 for connecting the water injection branch port with the annular airbag 3. When it is necessary to reduce or prevent the outflow of vaginal irrigation fluid, before irrigation, the three-way valve 6 at the water injection branch port is turned to connect the water injection pipe 12 with the vaginal water injection channel 21. Physiological saline is injected using a syringe to expand the annular airbag 3 so that its circumference is as close to the inner wall of the vaginal opening as possible, thereby reducing and preventing subsequent leakage of irrigation fluid.

[0043] The irrigation tube 13 is provided with an irrigation branch port, which is equipped with a three-way valve 6. A vaginal irrigation channel 22 is provided within the vaginal irrigation tube 2 and communicates with the irrigation branch port. When the vagina is to be irrigated, the three-way valve 6 at the irrigation branch port is turned to connect the irrigation tube 13 with the vaginal irrigation channel 22, thereby allowing a cleaning fluid such as saline to be flushed into the vagina. The outlet tube 14 is provided with an outlet branch port, and a vaginal outlet channel 23 is provided within the vaginal irrigation tube 2 and communicates with the outlet branch port. Multiple outlet ports 5 are provided on the sidewall of one end of the vaginal irrigation tube 2, which is located within the vagina. Flushing fluid within the vagina can be discharged through the vaginal outlet channel 23 and the outlet tube 14. The outlet tube 14 is connected to any one of a liquid receiving container, a drainage bag, a urine bag, and the like.

[0044] In other embodiments besides this one, to further ensure safety and prevent backflow of discharged liquid, two one-way valves 4 can be provided. Specifically, a one-way valve 4 can be provided on each side of the vaginal outlet channel 23 and the urinary catheter outlet channel 113 near the outlet pipe 14, thereby preventing backflow of liquid. Alternatively, another arrangement of the one-way valve 4 is to provide a one-way valve 4 on the outlet pipe 14 near the urinary catheter outlet channel 113, while the vaginal outlet channel 23 is connected to a tube end near the outlet pipe 14. A one-way valve 4 can be provided on the vaginal outlet channel 23 at this location, also effectively preventing backflow of liquid in the vaginal outlet channel 23 and the urinary catheter outlet channel 113. It is worth emphasizing that the location of the one-way valve 4 can be adjusted as needed, as long as it effectively prevents backflow of liquid in the vaginal outlet channel 23 and the urinary catheter outlet channel 113. A person skilled in the art can also achieve this by simply changing the location of the one-way valve 4 based on the above, and this should fall within the scope of protection of the present invention. The three-way valve 6 in this embodiment is a spherical three-way valve 6. A handle 8 for rotating and switching the spherical three-way valve 6 is provided on the outer wall of the corresponding pipeline. A color mark can also be provided on the handle 8 to facilitate distinguishing the direction of the three-way valve 6.

[0045] In other embodiments other than this embodiment, there can be two branch pipes, including a water injection pipe 12, a liquid outlet pipe 14, and three channels inside the vaginal irrigation tube 2, two of which are connected with the water injection pipe 12 and the liquid outlet pipe 14 in the same structure as above, and the other is directly connected with the external pipeline for irrigation; this design method can be used in situations where bladder irrigation is not required and only vaginal irrigation is required; in terms of cost, this method is advantageous; in terms of applicability, the method in which the branch pipes of the aforementioned embodiment include a water injection pipe 12, a irrigation pipe 13, and a liquid outlet pipe 14 is better; both belong to the protection scope of this technical solution.

[0046] This embodiment also discloses a method for using the vaginal irrigation and urinary catheterization device:

[0047] 1. Disinfection

[0048] During the pre-treatment care for the after-treatment, a small rubber sheet and a treatment towel are placed under the patient's buttocks, and the patient is asked to lie on the treatment bed in the lithotomy position. The operator uses tweezers to pick up an iodine cotton ball and disinfect the urethral opening, vaginal opening and their surroundings; protect the bed sheet from contamination, ensure the sterility of the operation, and prevent the occurrence of infection.

[0049] 2. Pipeline insertion

[0050] Insertion of urinary catheter: Figure 2As shown, the operator holds the catheter 1 and inserts it into the bladder through the urethra to drain urine. After the catheter 1 is inserted into the bladder, the operator uses the port of the syringe to insert the water injection valve 121, pushes the syringe through the water injection pipe 12 to inject physiological saline into the airbag 3, causing the airbag 3 to expand. The catheter 1 is gently pulled outward, and the airbag 3 blocks the bladder opening to prevent the catheter 1 from falling out of the bladder.

[0051] Insertion of the vaginal irrigation tube: After opening the vaginal opening with a vaginal dilator, insert the vaginal irrigation tube 2 into the appropriate position, turn the handle 8 on the water injection tube 12 to switch the three-way valve 6, so that the water injection tube 12 is connected to the vaginal water injection channel 21, and use a syringe to inject physiological saline to expand the annular airbag 3 so that its circumference fits the inner wall of the vaginal opening as much as possible, thereby achieving fixation and reducing and avoiding leakage of subsequent irrigation fluid.

[0052] 3. Rinse

[0053] Bladder irrigation: physiological saline flushing liquid is introduced through the flushing tube 13 and enters the bladder through the urinary catheter flushing channel 112 to achieve flushing of the bladder; the flushing liquid then flows from the urinary catheter outlet channel 113 through the outlet tube 14 and is discharged.

[0054] Vaginal irrigation: Turn the handle 8 on the irrigation tube 13 to switch the three-way valve 6, connecting the irrigation tube 13 to the vaginal irrigation channel 22, thereby allowing physiological saline to be flushed into the vagina for cleaning; the irrigation fluid in the vagina can flow from the vaginal outlet channel 23 through the outlet tube 14 and be discharged. When the irrigation fluid stops entering, continue suctioning for approximately 5-30 seconds; then use a syringe to extract the gas in the airbag. Because the dilator opens the vagina, the medical staff can see the internal situation. If there is any residual liquid inside, the vaginal irrigation tube can be gently pushed inward manually to absorb the remaining liquid. In other embodiments besides this one, negative pressure suction can be designed as needed during drainage.

[0055] 4. After the douche is complete, remove the vaginal douche tube 2, leave the urinary catheter 1 in place, and start the afterload treatment. Remove the urinary catheter 1 after the afterload treatment is complete.

[0056] Example 2

[0057] The difference between this embodiment and embodiment 1 is that, due to the different cervical lengths of some patients, in order to avoid the vaginal irrigation tube 2 being inserted too much and damaging the lesion, the present technology is to bond and fix the vaginal irrigation tube 2 near the tube head airbag 3 as shown in FIG. Figure 3The chuck 7 shown is 5 cm away from the tube head at the right end of the vaginal irrigation tube 2 (according to research, the normal length of the vagina of an adult female is 7 to 12 cm, so this technology can be designed to be 5 cm. In other embodiments other than this technology, different distance specifications can be set according to different situations); when inserted, the chuck 7 is outside the vagina, which can clearly let the operator know the insertion situation and whether it is over-inserted.

[0058] In other embodiments other than this embodiment, the chuck 7 can be set to be detachably connected. Figure 4 As shown, this technology provides scale lines or marking lines on the vaginal irrigation tube 2. The material of the chuck 7 can be rubber, silicone, etc. Figure 5 As shown, the chuck 7 has a through hole in the middle, and a slit 71 is cut into one side of the chuck 7. The chuck 7 can be opened along the slit 71 to form a C-shape and then securely attached to the vaginal irrigation tube 2. This design facilitates adjustment of the chuck 7's position as needed during treatment. To further prevent the chuck 7 from being displaced by the reverse force of the vaginal irrigation tube 2 after it abuts the vaginal opening or the dilator, spherical protrusions 72 are circumferentially spaced along the inner wall of the through hole. When the chuck 7 is attached to the vaginal irrigation tube 2, the flexible tube 2 deforms slightly, allowing it to fit into the slit 71 between the two spherical protrusions 72, further enhancing its anti-slip effect. Furthermore, when irrigation fluid is introduced into the vaginal irrigation tube 2, the fluid further expands the tube 2, which in turn helps stabilize the tube wall 2 in the slit 71 between the two spherical protrusions 72, further enhancing its stability.

[0059] At the same time, inclined supports 73 are arranged in a circle on the outer wall of the chuck 7 on the side away from the human body, and the supports 73 are staggered with the spherical protrusions 72. Since the supports 73 are correspondingly arranged between adjacent spherical protrusions 72, and the wall of the vaginal irrigation tube 2 is slightly convex between the two spherical protrusions 72, the supports 73 can be pressed against each protrusion of the vaginal irrigation tube 2, further increasing the stability. If the vaginal irrigation tube 2 is pushed inward again by external force, the supports 73 can be further pressed against the wall of the vaginal irrigation tube 2, preventing the vaginal irrigation tube 2 from moving inward. At the same time, the chuck 7 and the vaginal irrigation tube 2 are tightly fitted. This design greatly avoids the risk of the vaginal irrigation tube 2 moving inward during vaginal irrigation, and avoids the risk of the tube damaging the lesion. In other embodiments other than this embodiment, a scale mark can also be set on the catheter and matched with the chuck to limit its maximum insertion depth.

[0060] Example 3

[0061] The difference between this embodiment and embodiment 1 is that the liquid outlet pipe 14 is set on the central axis of the main pipeline, and the liquid inlet flushing pipe 13 is set on the outside of the main pipeline. With this design, the flushing liquid entering the bladder or vagina can be sprayed out from the side; and the diameter of the liquid outlet pipe 14 located on the central axis of the main pipeline can be set to be larger than the diameter of the flushing pipe 13, thereby improving the discharge efficiency. Figure 6 As shown, the central portion of the main urethra 11 is a urinary outlet channel 113, with a urinary injection channel 111 located on the upper side and a urinary irrigation channel 112 located on the lower side. The central portion of the vaginal irrigation tube 2 is a vaginal outlet channel 23, with a vaginal injection channel 21 located on the upper side and a vaginal irrigation channel 22 located on the lower side. Both the urinary outlet channel 113 and the vaginal outlet channel 23 are equipped with a one-way valve 4 at the end away from the airbag 3. The water injection tube 12 and the irrigation tube 13 are both equipped with a three-way valve 6, similar to that in Example 1.

[0062] Example 4

[0063] This embodiment discloses a urinary catheter made of a shape-memory polymer. The shape-memory polymer material consists of two phases: a reversible phase that changes from a glassy state to a rubbery state with temperature, and a stationary phase that maintains its initial shape. When exposed to external temperature stimulation, the shape-memory polymer can return to its original shape from a temporary state. The catheter is refrigerated and, after removal, remains hard but slightly pliable at room temperature, facilitating insertion into the bladder. At temperatures between 35°C and 45°C, it gradually softens into a soft, rubbery state, allowing it to conform to the urethra. Because the catheter in this technology includes a urinary irrigation channel 112, the saline solution introduced during irrigation is kept at a temperature between 37°C and 40°C, further ensuring its softening and rubberization. In other embodiments besides this one, a vaginal irrigation catheter made of a shape-memory polymer can also be used.

[0064] The present technology also discloses a combined tube package, including a sealed packaging bag and a urinary catheter; when stored, the package is dried and refrigerated at a low temperature, and the temperature can be set at 2-8° C. In other embodiments other than this embodiment, the packaging bag can be filled with an inert gas for protection.

[0065] This embodiment also discloses another technical solution. The aforementioned urinary catheter within the sealed packaging bag is the integrated vaginal irrigation and urinary catheterization device for improving the efficiency of post-treatment pre-treatment care, as described in Example 1. In other embodiments other than this embodiment, the urinary catheter and / or vaginal irrigation tube includes a front section and a rear section. The front section is the portion intended to penetrate deeply into the human body and is a shape memory polymer tube.

[0066] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
