Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for preventing blockage of a urinary catheter. Background Technology

[0002] In the treatment of urinary system diseases, it is often necessary to use a ureterostomy tube to help patients drain urine in order to solve problems such as urethral obstruction and neurogenic bladder dysfunction that cause difficulty in urination.

[0003] The applicant discovered through a search that a Chinese patent discloses "Anti-dislodgement bladder catheter" with publication (announcement) number "CN216824445U". This patent mainly combines a mushroom-shaped head with a drainage hole with a balloon, which not only allows urine to be smoothly discharged through the soft catheter, but also effectively prevents the soft catheter from dislodging and does not cause excessive irritation to the patient's bladder wall. The setting of the fixing unit can effectively fix the soft catheter, avoiding the use of traditional suture fixing methods and reducing the patient's pain. However, this device cannot perform flushing work to effectively prevent blockage. Therefore, we propose an anti-blockage device for a ureterostomy catheter. Utility Model Content

[0004] The purpose of this invention is to provide a device for preventing blockage of a ureterostomy tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ureterostomy tube anti-blockage device, comprising a flexible catheter, a fixing ring provided around the flexible catheter, the fixing ring having an array of through holes, a first delivery tube and a second delivery tube connected inside the through holes, the lower end of the first delivery tube being connected to a cleaning connector, the upper end of the first delivery tube penetrating through the side of the flexible catheter and being connected to an annular water outlet head at the upper end, the lower end of the second delivery tube being connected to a medicine connector, the upper end of the second delivery tube penetrating through the side of the flexible catheter and being connected to a medicine spray head at the upper end.

[0006] As a further embodiment of this utility model: the fixing ring is provided in two sets, and a connecting sleeve is provided on the side. The annular water outlet head and the medicine spray head are both located inside the soft conduit, and the annular water outlet head is located below the medicine spray head.

[0007] As a further embodiment of this utility model: both the cleaning tube and the medicine tube are provided with a sealing interface at their lower ends, and a connecting plate is connected to their sides. The connecting plate is located on the side of the lower end of the flexible conduit.

[0008] As a further embodiment of this utility model: the soft catheter is provided with two sets of one-way valves inside, and the opening direction of the one-way valves is towards the lower end of the soft catheter.

[0009] As a further embodiment of this utility model: the upper end of the soft conduit is provided with an inflatable air bladder, and the side is provided with a flow guide hole.

[0010] As a further aspect of this utility model, the soft catheter is provided with scale lines.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. This utility model features a fixing ring around the periphery of the flexible catheter, connecting a first delivery tube and a second delivery tube. The annular water outlet connected to the first delivery tube enables flushing. Medical staff can inject flushing fluid through the cleaning connector. The flushing fluid travels along the tube to the annular water outlet, flushing the lumen inside the flexible catheter. This effectively disperses and removes crystals, sediment, and impurities that may clog the lumen, significantly reducing the risk of catheter blockage. Simultaneously, the two sets of one-way valves inside the flexible catheter, with their opening direction facing the lower end of the catheter, effectively prevent urine backflow, avoiding infection caused by urine reflux into the urinary system and preventing impurities from re-entering the lumen and accumulating during backflow, thus preventing blockage.

[0013] 2. The dispensing nozzle connected to the second delivery tube of this utility model can be used to deliver medication. For conditions such as inflammation that may occur in the urinary system, the corresponding therapeutic drugs are injected through the medication delivery tube. The medication is evenly sprayed from the dispensing nozzle into the tube and related parts of the urinary system, playing a role in local treatment, infection prevention, and tissue repair, which helps to improve the patient's treatment experience.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 - Appendix Figure 5 This utility model discloses a device for preventing blockage of a ureterostomy tube. A fixed ring 2 is provided around the soft catheter 1. The fixed ring 2 has a series of through holes. A first delivery tube 3 and a second delivery tube 4 are connected inside the through holes. The lower end of the first delivery tube 3 is connected to a cleaning connector 5. The upper end of the first delivery tube passes through the side of the soft catheter 1 and is connected to an annular water outlet 6. The flushing fluid injected from the cleaning connector 5 can smoothly reach the annular water outlet 6 along the first delivery tube 3 and then be sprayed out into the lumen from the annular water outlet 6. The lower end of the second delivery tube 4 is connected to a medicine connector 7. The upper end of the second delivery tube passes through the side of the soft catheter 1 and is connected to a medicine nozzle 8. The medicine connector 7 can be connected to a container for holding various therapeutic agents.

[0024] In Example 1, the fixing ring 2 is provided in two sets and a connecting sleeve is provided on the side. The annular water outlet 6 and the medicine spray nozzle 8 are both located inside the flexible conduit 1. The annular water outlet 6 is located below the medicine spray nozzle 8. The cleaning pipe 5 and the medicine pipe 7 are both provided with sealing interfaces at their lower ends and are connected to connecting plates on their sides. The connecting plates are located on the lower side of the flexible conduit 1.

[0025] Specifically, the fixing rings 2 are reasonably distributed around the periphery of the flexible catheter 1, and the connecting sleeve can be easily connected to external auxiliary fixing devices or other related supporting components. The dispensing nozzle 8 is located above the annular water outlet 6. When it is necessary to deliver drugs to the relevant parts of the urinary system, the drugs injected through the drug delivery tube 7 will come to the dispensing nozzle 8 along the second delivery tube 4, and then be evenly sprayed in the upper part of the interior of the flexible catheter 1 and deeper into the urinary system. The sealing interface effectively prevents leakage during the injection of flushing fluid or drugs. The connecting plate plays a role in fixing the cleaning tube 5 and the drug delivery tube 7.

[0026] In Example 2, the soft catheter 1 is provided with two sets of one-way valves 9 inside. The opening direction of the one-way valves 9 is towards the lower end of the soft catheter 1. The upper end of the soft catheter 1 is provided with an inflatable air bladder, and the side is provided with a flow guide hole. The soft catheter 1 is provided with scale lines.

[0027] Specifically, the one-way valve 9 can effectively prevent external bacteria or impurities that have been drained from the catheter from being brought back into the urinary system when urine refluxes, thereby greatly reducing the risk of urinary tract infection and blockage caused by impurities re-accumulating in the catheter. The inflatable balloon plays a key role in the process of inserting the stoma tube into the corresponding part of the body and in the subsequent fixation ring 2. When the soft catheter 1 is inserted into the patient's body, medical staff can accurately determine the depth of the catheter insertion by observing the scale lines on the exposed part of the soft catheter 1.

[0028] Working principle:

[0029] When the device is first put into use, the flexible catheter 1 is responsible for urine drainage. The two sets of fixing rings 2 on its periphery have through holes connecting the first delivery capillary tube 3 and the second delivery capillary tube 4, playing an important auxiliary role. When it is necessary to flush the inside of the flexible catheter 1 to prevent blockage, medical staff can inject flushing fluid through the cleaning connector 5 (whose lower sealed interface can be connected to an external flushing fluid source). The flushing fluid is delivered through the first delivery capillary tube 3 and finally sprayed out from the annular outlet 6 located inside and above the flexible catheter 1. The annular spray pattern thoroughly flushes the lumen, dispersing and removing crystals, sediment, and other impurities in the urine, reducing the risk of blockage. For possible inflammation of the urinary system, the medication connector 7 (also with a sealed lower interface) can be used. The corresponding therapeutic drug is injected into the second delivery tube 4 through the container holding the drug. The drug is then evenly sprayed into the soft catheter 1 and related parts of the urinary system by the dispensing nozzle 8, providing local treatment. At the same time, the two sets of one-way valves 9 inside the soft catheter 1 open downwards, ensuring that urine is discharged smoothly when there is normal urine drainage. If there is a tendency for urine to flow back, the one-way valves 9 will close quickly to prevent the backflowing urine from bringing external bacteria back into the urinary system and to avoid the re-accumulation of impurities that could cause blockage. The inflatable balloon at the upper end of the soft catheter 1 can be inflated or filled with liquid to secure the catheter. The drainage hole on the side facilitates the smooth flow of urine into the catheter, and the graduation lines on the catheter allow medical staff to accurately control the depth of insertion into the body. At this point, the entire workflow is complete.
