[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to the attached drawings of the specification Figures 1-4, A leak-proof triple-lumen urinary catheter, including a triple-lumen catheter connector 1. One end of the triple-lumen catheter connector 1 is threadedly connected to a connector 2. The other end of the connector 2 is inserted with a catheter body 3. An insertion groove 4 is opened inside the catheter body 3. The catheter body 3 is inserted inside the insertion groove 4. A placement groove 5 is opened on the side of the insertion groove 4. A moving groove 6 is opened on the side of the placement groove 5. A moving rod 7 is inserted inside the moving groove 6. One end of the moving rod 7 is fixedly connected with a limiting pad 10; by pulling the moving rod 7, the limiting pad 10 fits and clamps the catheter body 3 and releases the clamping, achieving the purpose of quickly disassembling the catheter body 3 and the connector 2, improving the convenience of operating the device; the main advantage of this design is that it can achieve the quick loading and unloading of the urinary catheter in a short time. Especially in clinical applications, time and efficiency are often crucial factors. Quick disassembly can not only reduce the operation time but also reduce the discomfort of patients. In addition, the compactness and delicate design of this structure enable the entire device to maintain stability without adding an extra burden. When the limiting pad 10 contacts the catheter body 3, it can provide sufficient friction to ensure that there will be no accidental slippage during use. At the same time, the fitting design of the limiting pad also takes into account the flexible material characteristics of the urinary catheter, avoiding excessive compression or damage to the urinary catheter during clamping. To sum up, this design of clamping and releasing the limiting pad 10 through the moving rod 7 not only improves the operation convenience but also increases the use safety and durability of the entire device.

[0020] Then, the outer end of the moving rod 7 is fixedly connected with a pulling ring 9. The pulling ring 9 is arranged in a ring shape. The outer wall of the pulling ring 9 is provided with anti-slip lines; the design of the pulling ring 9 not only increases the convenience of use but also further optimizes the operation stability. The ring structure enables the operator to more easily hold the pulling ring with fingers or hands. Whether in the case of wet hands or insufficient hand strength, the operation can be easily completed. The anti-slip line design of the pulling ring is a consideration of the actual use environment. Especially in the medical scenario, the operator may wear gloves or there may be liquid residues on the hands, which may affect the operation stability of the device. With the addition of anti-slip lines, the pulling ring can still provide a reliable grip in these situations, preventing finger slippage. In addition, the design of the pulling ring can also be customized in terms of size and material according to the needs of different users to further improve the user experience and device adaptability. Generally speaking, the design of the pulling ring 9 reflects the humanized consideration of the device, which not only conforms to ergonomics but also improves the convenience and safety of actual operation.

[0021] Subsequently, a spring 8 is wound around the outer end of the moving rod 7. One end of the spring 8 is fixedly connected to the outer wall of the connecting head 2, and the other end of the spring 8 is fixedly connected to the moving rod 7. The elastic property of the spring 8 can preferably drive the device to perform a reset movement. The addition of the spring 8 provides an automatic reset function for the device, which is particularly important in multiple operations. Through the elastic force of the spring, the moving rod 7 can automatically return to the initial position after being pulled. This not only reduces the trouble of manual reset but also effectively avoids equipment damage or misuse caused by operation errors. During frequent operations, the elastic property of the spring can also remain consistent and will not weaken due to long-term use. This design improves the service life of the device while reducing the maintenance cost.

[0022] Next, there are two groups of moving rods 7 provided on the limiting pad 10, and the outer walls of each group of moving rods 7 are in mutual contact with the inner wall of the moving groove 6. Through this mechanism, the moving rod 7 can drive the limiting pad 10 more stably, thus ensuring the normal operation of the limiting pad 10 inside the placement groove 5. By providing two groups of moving rods 7, the stability of the limiting pad 10 inside the placement groove 5 is ensured. This structural design avoids the imbalance problem that may be caused by a single moving rod, thereby ensuring the smooth operation of the entire device. The close contact design between the moving rod 7 and the inner wall of the moving groove 6 further improves the accuracy of the device, enabling the limiting pad 10 to move smoothly on the track and reducing the risk of jamming or deviation.

[0023] Then, a rubber pad is provided on the inner wall of the limiting pad 10, and the rubber pad provided on the inner wall of the limiting pad 10 is in mutual contact with the outer wall of the catheter tube body 3. The application of the rubber pad plays a crucial role in this design. Since the catheter tube body 3 is usually made of flexible material, direct contact with the hard limiting pad may cause damage or sliding of the tube body. The introduction of the rubber pad not only protects the tube body but also provides additional friction, making the clamping effect more firm. The flexibility of the rubber pad enables it to better adapt to the surface profile of the catheter and form a tight contact, thereby improving the clamping stability.

[0024] It should be noted that the limiting pads 10 are symmetrically arranged inside the placement groove 5. The symmetrically arranged structure of the limiting pads 10 not only improves the aesthetics of the device but, more importantly, greatly enhances the clamping balance. The symmetrical design ensures that the catheter tube body 3 can be evenly stressed and will not deform or become unstable due to excessive unilateral stress. The two groups of limiting pads 10 can clamp the catheter tube body 3 simultaneously during operation, effectively reducing the shaking of the tube body inside the connecting head 2, thereby improving the stability and safety of the entire system.

[0025] The following points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. The terms "upper", "lower", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change;

For other structures, reference can be made to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0027] Finally, the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
