Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an easy-to-use super-slippery intermittent urinary catheter kit. Background Technology

[0002] For patients with neurogenic bladder caused by spinal cord injury, long-term reliance on indwelling catheters can lead to gradual bladder function deterioration, even when kidney, bladder, and urethral functions remain normal. Therefore, clinicians generally recommend intermittent catheterization to maintain and preserve bladder function.

[0003] Super-slippery intermittent catheters are commonly used in clinical and home catheterization. The catheter's shaft has a super-slippery coating composed of a hydrophilic lubricant. To use it, the catheter pouch needs to be torn open, the catheter removed, and placed in water to allow the super-slippery coating to fully wet and swell before insertion into the urethra or bladder. However, this step requires prior preparation of a water source and soaking container, which is inconvenient for users. To simplify the procedure, some users choose to directly inject water into the catheter pouch, using the pouch as a soaking container to moisten the super-slippery coating. However, this practice has potential problems:

[0004] Most urinary catheter kits on the market currently use paper-plastic packaging, and their inner surfaces are usually coated with adhesives (such as water-soluble or hot melt adhesives) for sealing purposes. In environments with high relative humidity, the super-slippery coating of the catheter may adhere to the packaging material and detach, or the adhesive on the packaging may adhere to the catheter, thus contaminating the super-slippery intermittent catheter and reducing the product's safety and effectiveness. Furthermore, some outer packaging may leak after a certain period of time due to water immersion, further increasing the risk of use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing an easy-to-use, super-slippery intermittent urinary catheter kit. This kit not only eliminates the need for additional water sources and soaking containers, but also effectively prevents adhesive contamination of the urinary catheter, improving the safety and effectiveness of the product. At the same time, it also prevents leakage of the outer packaging when it is wetted with water, reducing the risk of use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An easy-to-use, ultra-slippery intermittent urinary catheter kit includes an outer packaging, a sealed cavity within the outer packaging, and a catheter within the cavity. The catheter includes a connector and a tube body for insertion into the urethra. One end of the connector has an outlet, and the other end of the tube body has an inlet. The outlet and inlet communicate to form a urine drainage channel. The kit is characterized by: one end of the cavity having an easy-tear opening; the connector of the catheter being located adjacent to the opening; a water reservoir between the connector and the opening; one end of the water reservoir being inserted into the outlet of the connector and having an easy-break opening; the water reservoir containing a lubricating solution for lubricating the tube body; an anti-contact membrane covering the outer periphery of the connector; and a protective bag covering the outer periphery of the tube body, with the opening of the protective bag facing the connector, and at least two-thirds of the tube body submerged in the opening of the protective bag.

[0008] The technical problem to be solved by this utility model can be further achieved through the following steps: the anti-contact film is specifically a cylindrical plastic film with openings at both ends; the anti-contact film and the connector are in clearance fit so that the anti-contact film can slide relative to the connector.

[0009] The technical problem to be solved by this utility model can be further achieved through the following steps, wherein the protective bag is specifically a plastic bag.

[0010] The technical problem to be solved by this utility model can be further achieved through the following steps: the outer packaging is provided with an easy-hanging structure at one end near the opening.

[0011] The technical problem to be solved by this utility model can be further achieved through the following steps: the easy-hanging structure is a fixing sticker with double-sided adhesive, and the surface of the fixing sticker is provided with release paper.

[0012] The technical problem to be solved by this utility model can be further achieved through the following steps: the outer packaging is specifically a paper-plastic packaging, which includes a lower cardboard and an upper sealing mold. The edge of the upper sealing mold is sealed to the upper surface of the lower cardboard, and the accommodating cavity is formed between the lower cardboard and the upper sealing mold.

[0013] The technical problem to be solved by this utility model can be further achieved through the following steps: the easy-tear structure is an unsealed tear-away interlayer, which is formed by the lower cardboard and the upper sealing mold extending together after sealing the edge on the side near the opening.

[0014] The technical problem to be solved by this utility model can be further achieved through the following steps, wherein the soaking solution is sterile water.

[0015] The technical problem to be solved by this utility model can be further achieved through the following steps: one end of the connector is inserted into the opening of the protective bag.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: by inserting a water storage bag into one end of the connector and covering the tube body with a protective bag, not only is there no need to prepare additional water source and soaking container, but since the tube body and water do not come into contact with the outer packaging throughout the process, it can also effectively prevent the adhesive from contaminating the catheter and avoid leakage of the outer packaging bag or seal due to water immersion, thus taking into account both convenience and safety; in addition, the anti-touch film that slides on the connector can effectively prevent direct contact with the tube body surface due to accidental slippage when handling the catheter.

[0025] Please refer to Figure 1-5A user-friendly, ultra-slippery intermittent urinary catheter package includes an outer packaging 1, a sealed cavity 2 within the outer packaging 1, and a urinary catheter 3 within the cavity 2. The urinary catheter 3 includes a connector 4 and a tube body 5 for insertion into the urethra. The connector 4 and the tube body 5 are fixedly connected. The outer surface of the tube body 5 is coated with an ultra-slippery coating. One end of the connector 4 has an outlet 6, and the other end of the tube body 5 has an inlet 7. The outlet 6 and the inlet 7 form a urine drainage channel 8. One end of the cavity 2 has an easy-tear opening mechanism. The connector 4 of the catheter 3 is positioned adjacent to the opening 9 of the catheter body 5. A water reservoir 10 is provided between the connector 4 and the opening 9. One end of the water reservoir 10 is inserted into the urinary outlet 6 of the connector 4 and has a tear-resistant opening 11. The water reservoir 10 contains a soaking solution 12 for lubricating the catheter body 5. An anti-contact membrane 13 is fitted around the outer periphery of the connector 4, and a protective bag 14 is fitted around the outer periphery of the catheter body 5. The opening 18 of the protective bag 14 faces the connector 4, and at least 2 / 3 of the catheter body 5 is submerged in the opening 18 of the protective bag 14. The opening 18 of the protective bag 14 can further cover one end of the connector.

[0026] The anti-contact membrane 13 is specifically a cylindrical plastic film open at both ends. The anti-contact membrane 13 and the connector 4 are fitted with a clearance, allowing the anti-contact membrane 13 to slide relative to the connector 4. A stop ring is fixedly provided at one end of the connector 4 near the opening 9 to stop the anti-contact membrane 13. With this design, even if the catheter 3 is accidentally slipped while holding the connector 4 to remove it, or while performing catheterization, the anti-contact membrane 13 can slide with the hand, preventing direct contact between the hand and the tube body 5 of the catheter 3, thereby preventing contamination.

[0027] The protective bag 14 is specifically a waterproof plastic bag, such as a PE / PP embossed bag.

[0028] The outer packaging 1 is provided with an easy-hanging structure at one end near the opening 9, so that the outer packaging 1 can be hung on a hook, rope or other fixed device to avoid fatigue caused by the person holding it when soaking in the super slippery coating.

[0029] The aforementioned easy-hanging structure is a fixing sticker 15 with double-sided adhesive, and the surface of the fixing sticker 15 is provided with release paper. In addition, the easy-hanging structure can also be other structures commonly found in the prior art, such as hook holes / slots or hooks with elastic cords.

[0030] Please refer to Figure 5 The outer packaging 1 is specifically a paper-plastic packaging, which includes a lower cardboard 16 and an upper sealing mold 17. The edge of the upper sealing mold 17 is sealed to the upper surface of the lower cardboard 16, and the accommodating cavity 2 is formed between the lower cardboard 16 and the upper sealing mold 17.

[0031] The tearable structure is an unsealed tearable interlayer 19, which is formed by the lower cardboard 16 and the upper sealing mold 17 extending together after sealing on the side near the opening 9.

[0032] The soaking solution 12 is sterile water, which can be produced by aseptic filling or subsequent radiation sterilization.

[0033] Working principle: This utility model provides a convenient and easy-to-use super-slippery intermittent urinary catheter pack (3 packs). In use, first place the pack with the opening 9 facing upwards. Figure 3 Then, the water storage bag 10 is squeezed from the outside of the outer packaging 1, causing the easily ruptured opening 11 of the water storage bag 10 to break. At this time, sterile water flows from the urine outlet 6 into the drainage channel 8 and flows out from the urine inlet 7 into the protective bag 14, thereby immersing and lubricating the super-slippery coating on the outer surface of the tube body 5. Figure 4 Because the protective bag 14 is confined within the receiving cavity 2, and the opening 18 of the protective bag 14 is located above the tube body 5, sterile water will not leak from the opening 18 and come into contact with the outer packaging 1, effectively preventing adhesive contamination of the catheter 3 and avoiding leakage of the outer packaging 1 due to water immersion. After the super-slippery coating has fully swelled, peel off the release paper on the surface of the fixing sticker 15, and stick the catheter 3 to the wall or other object surface, keeping the super-slippery intermittent catheter pack vertical with the opening 9 facing upwards. Finally, open the outer packaging 1 from the opening 9, pinch the anti-contact film 13 and the connector 4 of the catheter 3, and remove them together with the water storage bag 10. Discard the water storage bag 10, and then hold the connector 4 and the anti-contact film 13 for routine catheterization. The anti-contact film 13 effectively prevents direct contact with the tube body surface due to accidental slippage when holding the catheter 3, ensuring hygiene and safety during use.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
