Description

Technical Field

[0001] This utility model relates to the field of medical devices for bladder irrigation, and in particular to an anti-reflux adjustable speed bladder irrigation device. Background Technology

[0002] Bladder irrigation is a common and important treatment method in the treatment of urinary system diseases. It is widely used after bladder and urethral surgery, and in patients with long-term indwelling catheters. Its purpose is to clean the bladder, prevent and control infection, and remove blood clots or foreign bodies from the bladder. However, traditional bladder irrigators have revealed many shortcomings in actual use, which seriously affect the treatment effect and patient experience.

[0003] Traditional bladder irrigators suffer from contamination due to backflow of the irrigation fluid. During irrigation, urine, along with any bacteria or impurities present in the patient's bladder, can easily flow back into the irrigation fluid bag or tubing. This reflux not only contaminates the irrigation fluid, rendering it sterile and ineffective for cleaning and treatment, but also increases the risk of reinfection of the urinary tract. For example, in immunocompromised patients, backflow contamination can lead to bacterial proliferation, potentially causing serious complications such as cystitis and pyelonephritis, prolonging hospital stays, and increasing patient suffering and financial burden.

[0004] When blockage occurs, traditional bladder irrigators require detaching the bladder irrigator and catheter for treatment. This procedure is not only cumbersome but also highly susceptible to contamination. During detachment, external bacteria can easily enter the urinary system, and bacteria may also remain at the interface between the irrigator and catheter, further increasing the risk of infection. Moreover, frequent detachment and reconnection of the bladder irrigator and catheter can lead to catheter displacement or dislodgement, causing additional pain and procedural risks for the patient.

[0005] Regarding speed adjustment, traditional bladder irrigators typically rely on healthcare professionals visually observing the drip rate within the Murphy drip chamber. This method is highly inaccurate, significantly influenced by factors such as the healthcare professional's experience, observation angle, and ambient lighting. For example, in nighttime or dimly lit ward environments, healthcare professionals may struggle to accurately judge the drip rate; different healthcare professionals may also have different standards for judging the drip rate, making precise control of the irrigation speed difficult. If the irrigation speed is too fast, it may cause discomfort such as bladder spasms and pain in the patient; if the irrigation speed is too slow, it may fail to effectively remove foreign objects and bacteria from the bladder in a timely manner, affecting the treatment outcome.

[0006] Traditional bladder irrigators also have limitations in terms of length adjustment. In actual use, patients' body shapes, positions, and bed heights vary, requiring irrigators with adjustable lengths to adapt to different usage scenarios. However, traditional bladder irrigators are often difficult to adjust in length. When the irrigator is too long, excess tubing can easily become tangled around the patient's bedside, not only affecting the patient's movement but also potentially causing accidental pulling when the patient turns over or moves, resulting in backflow of the irrigation fluid. When the irrigator is too short, it may not meet the distance requirements between the patient and the irrigation fluid bag, restricting the patient's range of motion and causing significant inconvenience.

[0036] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0038] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0039] Reference Appendix Figure 1 To be continued Figure 3As shown, a preferred embodiment of the present invention, an anti-reflux adjustable-speed bladder irrigator, is illustrated. A liquid bag 90 is adapted to be connected to the front end of the anti-reflux adjustable-speed bladder irrigator 1. A liquid 91 in the liquid bag 90 is adapted to flow through the anti-reflux adjustable-speed bladder irrigator 1 into a catheter device 80 and then into the patient's bladder to irrigate the bladder. The anti-reflux adjustable-speed bladder irrigator 1 prevents the liquid 91 from flowing back into the liquid bag 90 and causing contamination. Preferably, in this embodiment, two liquid bags 90 are simultaneously connected to the front end of the anti-reflux adjustable-speed bladder irrigator 1. Those skilled in the art should understand that the number of connected liquid bags 90 is not a limitation of the present invention. Furthermore, in this embodiment, the liquid 91 can be physiological saline or furacilin solution, etc.

[0040] For ease of explanation, in this embodiment, the end of the anti-reflux adjustable speed bladder irrigator 1 connected to the liquid bag 90 during use is taken as the front end of the anti-reflux adjustable speed bladder irrigator 1, and the end of the anti-reflux adjustable speed bladder irrigator 1 connected to the catheter device 80 is taken as the rear end of the anti-reflux adjustable speed bladder irrigator.

[0041] Figure 1 This is a schematic diagram of the overall structure of the anti-reflux adjustable-speed bladder irrigator 1 according to a first preferred embodiment of the present invention. In this embodiment, the anti-reflux adjustable-speed bladder irrigator 1 includes an anti-reflux component 10, a dropper component 20, a speed-adjusting component 30, and a connecting component 40. The anti-reflux component 10 is connected to the front end of the dropper component 20. The liquid bag 90 is adapted to be connected to the front end of the anti-reflux component 10. The liquid 91 in the liquid bag 90 is adapted to flow into the dropper component 20 through the anti-reflux component 10. The anti-reflux component 10 is adapted to restrict the backflow of the liquid 91 into the liquid bag 90. The speed-adjusting component 30 is disposed on the dropper component 20 to control the flow rate of the liquid 91. The connecting component 40 is disposed at the rear end of the dropper component 20 to connect the dropper component 20 and the catheter device 80.

[0042] Specifically, the anti-reflux adjustable speed bladder irrigator 1 is used to connect the liquid bag 90 and the urinary catheter device 80, so that the liquid 91 in the liquid bag 90 enters the urinary catheter device 80 after the speed is adjusted by the anti-reflux adjustable speed bladder irrigator 1, and irrigates the patient's bladder.

[0043] In an embodiment of this application, the urinary catheter device 80 includes an insertion tube 81, an input tube 82, an output tube 83, an inflation tube 84, and a balloon device 85. The insertion tube 81 is adapted to be inserted into the patient's bladder. The input tube 82, the output tube 83, and the inflation tube 84 are all connected to the front end of the insertion tube 81. The balloon device 85 is disposed on the insertion tube 81. When the insertion tube 81 is inserted into the patient's bladder, it is adapted to inflate the balloon device 85 by inflating or filling the inflation tube 84 with liquid, thereby fixing it in place within the patient's bladder. That is, the input tube 82 and the output tube 83 are both interconnected with the insertion tube 81, and the inflation tube 84 is connected to the balloon device 85. The drip assembly 20 of the anti-reflux adjustable-speed bladder irrigator 1 is detachably connected to the input tube 82 via the connecting assembly 40. The liquid 91 flows sequentially from the liquid bag 90 through the anti-backflow component 10, the dropper component 20, and the connecting component 40. Through the speed regulation component 30, it reaches the input tube 82 and enters the insertion tube 81 to flush the patient's bladder. Afterward, it flows out from the output tube 83. Medical staff observe the blood concentration of the outflowing liquid 91 and further adjust the speed regulation component 30 so that the liquid 91 flushes the patient's bladder at a suitable speed.

[0044] More specifically, the anti-backflow assembly 10 includes a connecting portion 11 and an anti-backflow portion 12. The connecting portion 11 is integrally connected to the front end of the anti-backflow portion 12, and the anti-backflow portion 12 is placed inside the dropper assembly 20. The connecting portion 11 is used to connect the liquid bag 90 so that the liquid 91 flows through the connecting portion 11, through the anti-backflow portion 12, and into the dropper assembly 20.

[0045] The connecting portion 11 includes a first connecting pipe 111, a second connecting pipe 112, and has a first connecting channel 113 and a second connecting channel 114. The first connecting channel 113 is located inside the first connecting pipe 111, and the second connecting channel 114 is located inside the second connecting pipe 112. In other words, the first connecting channel 113 extends rearward from the front end of the first connecting pipe 111 through the first connecting pipe 111 to communicate with the anti-backflow portion 12, and the second connecting channel 114 extends rearward from the front end of the second connecting pipe 112 through the second connecting pipe 112 to communicate with the anti-backflow portion 12. In an embodiment of this application, the first connecting pipe 111 and the second connecting pipe 112 are respectively connected to a liquid bag 90, such that the liquid 91 flows from the liquid bag 90 through the first connecting pipe 111 and the second connecting pipe 112 to reach the anti-backflow portion 12.

[0046] The anti-backflow section 12 includes an extension unit 121, an anti-backflow unit 123, and an extension cavity 122. The extension cavity 122 is disposed within the extension unit 121 and communicates with the first connecting channel 113 and the second connecting channel 114. The anti-backflow unit 123 is installed within the extension cavity 122. The anti-backflow unit 123 controls the specific flow direction of the liquid 91 between the connecting section 11 and the dropper assembly 20. That is, the liquid 91 is suitable to enter the dropper assembly 20 from the connecting section 11 through the anti-backflow unit 123, but the anti-backflow unit 123 can restrict the liquid 91 from flowing back from the dropper assembly 20 to the connecting section 11, thus avoiding contamination of the originally clean liquid 91 in the liquid bag 90.

[0047] It is worth mentioning that, in actual use, there is a potential risk that the liquid 91 may flow back from the dropper assembly 20 to the connecting part 11. During the flushing process, the liquid 91 may come into contact with bacteria, impurities, and other contaminants from the patient's body. If the liquid 91 flows back to the connecting part 11, it is highly likely that these contaminants will be carried back into the liquid bag 90, thus contaminating the originally clean liquid 91 inside the liquid bag 90. This would not only fail to effectively perform its flushing and treatment functions but could also introduce bacteria and other harmful substances into the patient's bladder, further aggravating the patient's condition. On the other hand, it can also effectively prevent tube blockage caused by the backflow of the liquid 91, reducing the probability of continuous blockage and ensuring smooth flushing. In particular, the anti-backflow unit 123 is implemented as a one-way flow membrane or a one-way flow valve.

[0048] More specifically, due to certain design limitations in clinical irrigation equipment, the dropper assembly 20 often becomes filled with liquid 91 during actual operation. Once the dropper assembly 20 is filled with liquid, it becomes difficult for medical staff to clearly observe the drip rate of liquid 91, which is crucial for determining whether irrigation is unobstructed and the patient's condition. When the drip rate cannot be accurately observed, medical staff cannot determine whether the patient has experienced abnormalities such as tube blockage, which not only affects the treatment process but may also pose a potential threat to the patient's health due to delayed treatment. The anti-backflow unit 123 prevents the dropper assembly 20 from becoming filled with liquid 91, overcoming the problem of difficulty in observation caused by liquid accumulation in the dropper assembly 20 in clinical practice.

[0049] In addition, the anti-reflux adjustable speed bladder irrigator 1, through the anti-reflux unit 123, in conjunction with the connecting part 11 and the drip assembly 20, allows medical staff to judge whether the patient's irrigation is unobstructed based on the drip rate of the drip assembly 20. When the liquid 91 stops dripping, the blockage can be detected in time.

[0050] The dropper assembly 20 includes a liquid-passing section 21 and a liquid-passing tube 22. The liquid-passing tube 22 is integrally connected to the liquid-passing section 21, and the connecting assembly 40 is provided at the rear end of the liquid-passing tube 22 to connect to the urinary catheter device 80. The liquid-passing section 21 has a liquid-passing cavity 211 located within the liquid-passing section 21. The liquid-passing tube 22 has a liquid-passing channel 221 located within the liquid-passing tube 22 and communicating with the liquid-passing cavity 211. The anti-reflux section 12 of the anti-reflux assembly 10 is placed within the liquid-passing cavity 211 of the liquid-passing section 21, and the connecting section 11 of the anti-reflux assembly 10 extends from the anti-reflux section 12 toward the front end to connect to the liquid bag 90. The liquid 91 is adapted to enter the liquid passage chamber 211 from the anti-backflow unit 123 through the anti-backflow section 12, and then flow through the liquid passage 221 to the connecting assembly 40.

[0051] The speed control component 30 is disposed in the liquid passage 22 of the dropper assembly 20. The speed control component 30 can adjust the drip rate of the liquid 91 according to the speed corresponding to a bladder irrigation colorimetric card, achieving precise control and improving the irrigation effect. That is to say, medical staff can observe the blood concentration of the liquid 91 flowing from the output tube 83 of the catheter device 80 and compare it with the bladder irrigation colorimetric card to further adjust the speed control component 30 so that the liquid 91 irrigates the patient's bladder at a suitable speed.

[0052] The connecting assembly 40 includes a transmission section 41 and a clearing section 42. The clearing section 42 is connected to the transmission section 41; in other words, the clearing section 42 extends outward from the surface of the transmission section 41. The two ends of the transmission section 41 are respectively connected to the liquid passage 22 of the dropper assembly 20 and the inlet tube 82 of the catheter device 80. When the anti-reflux adjustable-speed bladder irrigator 1 becomes blocked, medical personnel can clear the blockage by inserting a syringe into the clearing section 42. The clearing section 42 avoids the need to disassemble the dropper assembly 20 and the catheter device 80, facilitating irrigation by medical personnel and avoiding the waste and contamination caused by separating the anti-reflux adjustable-speed bladder irrigator 1 and then irrigating with a syringe.

[0053] The delivery unit 41 includes a delivery tube 411 and a delivery channel 412. The delivery channel 412 is located within the delivery tube 411; in other words, the delivery channel 412 extends from one end of the delivery tube 411 to the other end, penetrating the delivery tube 411. The two ends of the delivery tube 411 are respectively connected to the liquid passage 22 of the dropper assembly 20 and the inlet tube 82 of the catheter device 80. That is, the delivery channel 412 connects the liquid passage 221 of the liquid passage 22 and the inlet tube 82, facilitating the flow of the liquid 91 into the patient's bladder for flushing.

[0054] The unblocking section 42 includes an unblocking tube 421 and an unblocking interface 422. The unblocking tube 421 is connected to the delivery tube 411, and the unblocking interface 422 is disposed in the unblocking tube 421 to communicate with the delivery channel 412. A syringe is adapted to be inserted into the unblocking interface 422 to unblock the blockage. This avoids the need to disassemble the drip assembly 20 and the catheter device 80, facilitating flushing by medical personnel.

[0055] In summary, the anti-reflux adjustable-speed bladder irrigator 1 is equipped with the anti-reflux unit 123, which on the one hand prevents the liquid 91 from flowing back into the liquid bag 90 and causing contamination, and effectively avoids tube blockage caused by the backflow of the liquid 91, reducing the probability of continuous tube blockage and ensuring smooth irrigation. On the other hand, the anti-reflux unit 123 can prevent the drip assembly 20 from being filled with the liquid 91, overcoming the problem of difficulty in observation caused by the accumulation of liquid in the drip assembly 20 in clinical practice. Moreover, medical staff can judge whether the patient's irrigation is unobstructed based on the drip rate of the drip assembly 20 and promptly detect tube blockage.

[0056] Appendix 4 illustrates a second embodiment of the present invention providing an anti-reflux adjustable-speed bladder irrigator 1A. The anti-reflux adjustable-speed bladder irrigator 1A in this preferred embodiment is a variation of the first preferred embodiment described above. In this embodiment, the dropper assembly 20A is modified compared to the first preferred embodiment.

[0057] Similarly, in this embodiment, the anti-reflux adjustable-speed bladder irrigator 1 includes an anti-reflux component 10, a dropper assembly 20A, a speed-adjusting component 30, and a connecting component 40. The anti-reflux component 10 is connected to the front end of the dropper assembly 20A. The liquid bag 90 is adapted to be connected to the front end of the anti-reflux component 10. The liquid 91 in the liquid bag 90 is adapted to flow into the dropper assembly 20A through the anti-reflux component 10. The anti-reflux component 10 is adapted to restrict the backflow of the liquid 91 into the liquid bag 90. The speed-adjusting component 30 is disposed on the dropper assembly 20A to control the flow rate of the liquid 91. The connecting component 40 is disposed at the rear end of the dropper assembly 20A to connect the dropper assembly 20A and the catheter device 80.

[0058] It is worth mentioning that, in this embodiment, the anti-backflow component 10, the speed regulating component 30, and the connecting component 40 are all the same as in the above embodiments, so they will not be described again in this embodiment.

[0059] Specifically, in this embodiment, the dropper assembly 20A includes a liquid-passing section 21A and a liquid-passing tube 22A. The liquid-passing tube 22A is integrally connected to the liquid-passing section 21A, and the connecting assembly 40 is provided at the rear end of the liquid-passing tube 22A to connect to the urinary catheter device 80. The liquid-passing section 21A has a liquid-passing cavity 211A located within the liquid-passing section 21A. The liquid-passing tube 22A has a liquid-passing channel 221A located within the liquid-passing tube 22A and communicating with the liquid-passing cavity 211A. The anti-reflux section 12 of the anti-reflux assembly 10 is placed within the liquid-passing cavity 211A of the liquid-passing section 21A, and the connecting section 11 of the anti-reflux assembly 10 extends from the anti-reflux section 12A toward the front end to connect to the liquid bag 90. The liquid 91 is adapted to enter the liquid passage chamber 211A from the anti-backflow unit 123 through the anti-backflow section 12, and then flow through the liquid passage 221A to the connecting assembly 40.

[0060] The difference is that in this embodiment, the liquid passage pipe 22A further includes a first liquid passage pipe 222A and a second liquid passage pipe 223A. The first liquid passage pipe 222A and the second liquid passage pipe 223A are connected to each other. The front end of the first liquid passage pipe 222A is connected to the liquid passage part 21A, and the rear end is connected to the second liquid passage pipe 223A. The front end of the second liquid passage pipe 223A is connected to the first liquid passage pipe 222A, and the rear end is connected to the connecting component 40.

[0061] It is worth mentioning that the first fluid passage 222A is implemented as a telescopic tube, meaning that the length of the first fluid passage 222A can be adjusted. When the patient performs local activities, such as turning over, the fluid passage 22A may be squeezed, causing the fluid 91 to flow back. In this embodiment, the first fluid passage 222A is implemented as a telescopic tube with an adjustable length. When the patient performs local activities, such as turning over, the length of the first fluid passage 222A can be adjusted to allow the anti-reflux adjustable speed bladder irrigator 1 to better adapt to the patient's local activities and prevent the fluid from flowing back during the patient's activities. Specifically, the first fluid passage 222A can be implemented as a spring-loaded telescopic tube. Those skilled in the art should understand that the implementation of the first fluid passage 222A is not a limitation of this utility model.

[0062] Appendix 5 illustrates a third embodiment of the present invention, namely, an anti-reflux adjustable speed bladder irrigator 1B. The anti-reflux adjustable speed bladder irrigator 1B in this preferred embodiment is a variation of the first preferred embodiment described above. In this embodiment, the speed control component 30B has been changed compared to the first preferred embodiment.

[0063] Similarly, in this embodiment, the anti-reflux adjustable-speed bladder irrigator 1 includes an anti-reflux component 10, a dropper assembly 20, a speed-adjusting component 30B, and a connecting component 40. The anti-reflux component 10 is connected to the front end of the dropper assembly 20. The liquid bag 90 is adapted to be connected to the front end of the anti-reflux component 10. The liquid 91 in the liquid bag 90 is adapted to flow into the dropper assembly 20 through the anti-reflux component 10. The anti-reflux component 10 is adapted to restrict the backflow of the liquid 91 into the liquid bag 90. The speed-adjusting component 30B is disposed on the dropper assembly 20 to control the flow rate of the liquid 91. The connecting component 40 is disposed at the rear end of the dropper assembly 20 to connect the dropper assembly 20 and the catheter device 80.

[0064] It is worth mentioning that, in this embodiment, the anti-backflow component 10, the dropper component 20, and the connecting component 40 are all the same as in the above embodiment, so they will not be described again in this embodiment.

[0065] Specifically, in an embodiment of this application, the speed control component 30B includes a detection unit 31B and a control unit 32B. The detection unit 31B is electrically connected to the control unit 32B.
