Abstract
Description
Technical Field
[0001] This utility model belongs to the field of urine collection bag technology, specifically a pediatric urine collection bag. Background Technology
[0002] According to the search, a pediatric urine bag with announcement number CN219208341U can not only be tied to the child's leg to reduce the shaking of the reservoir bag when the child runs, but also has multiple baffles inside to separate the liquid in the reservoir bag, reduce the inertia of the liquid when the child runs, and thus reduce the occurrence of the child falling due to instability caused by the inertia of the liquid. The aforementioned shortcomings of pediatric urine collection bags: For female children, many pressing issues need to be addressed. Given the significant physiological differences between boys and girls, the physiological characteristics of female children dictate that their required urine collection bags differ drastically from those of male children. Typically, to effectively collect urine from female children, a wider collection opening design is required to fully cover their vulva. Although some existing technologies recognize the need for wider collection openings for female children, the actual results are still unsatisfactory. Even when the collection opening covers the vulva, leakage still occurs frequently. This is because the collection opening is too flat, preventing urine from flowing smoothly into the urine collection bag, leading to a risk of leakage over time. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a pediatric urine drainage bag, including a flow guide hood and a flow guide tube connected to the flow guide hood, as well as fastening structures located in front of and outside the flow guide hood. The fastening structure includes a collection cover for covering the vulva of a girl, which is connected to the flow guide cover; a flexible fitting sleeve installed in front of the collection cover; and two angled flow guide blocks installed on the inner wall of the collection cover to facilitate the flow of urine.
[0004] Preferably, the outer side of the collection cover is provided with six fitting straps evenly divided into three groups, and the outer wall of the flow guide cover is equipped with two binding straps for binding to the child's legs.
[0005] Preferably, a locking strap is installed at the end of each of the two binding straps that does not contact the flow guide, and the inner wall of each of the two binding straps is provided with an insertion groove that is adapted to the locking strap.
[0006] Preferably, the locking strap and the binding strap are fixed together by Velcro.
[0007] Preferably, the bottom of the drainage tube is connected to a urine drainage bag, which is made of medical plastic and has scale markings on its outer wall for observing the amount of urine inside.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a fastening structure, employing soft yet durable materials for the binding and locking straps. The Velcro closure ensures a secure fit around the child's thighs and allows for flexible adjustment based on thigh size, thus stabilizing the urine bag and significantly reducing the risk of leakage due to movement. The flexible, skin-friendly medical-grade silicone sleeve is attached to both sides of the vulva using adhesive tape for fixation. The tape has good adhesion without irritating the skin and can be adjusted to fit the shape of the vulva, ensuring a tight seal. After urine is produced, two angled guide blocks inside the sleeve direct the urine from the inner wall of the collection hood to the drainage hood, and then into the drainage tube, effectively preventing urine accumulation and further reducing the possibility of leakage.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] like Figures 1 to 5 As shown, this utility model provides a pediatric urine drainage bag, including a flow guide 1 and a flow guide tube 2 connected to the flow guide 1, as well as a fastening structure 3 located in front of and outside the flow guide 1. The fastening structure 3 includes a collection cover 31 connected to the flow guide cover 1 for covering the vulva of the girl, a flexible fitting sleeve 32 installed in front of the collection cover 31, and two inclined flow guide blocks 33 installed on the inner wall of the collection cover 31 to facilitate the flow of urine.
[0013] The above solution employs a fastening structure 3, with binding straps 35 and locking straps 36 made of soft yet durable materials. These are secured to the child's thighs using Velcro, allowing for flexible adjustment based on thigh size. This stabilizes the urine bag and significantly reduces the risk of leakage due to movement. The flexible fitting sleeve 32, made of skin-friendly medical-grade silicone, is attached to both sides of the vulva using a fitting strap 34. This strap has good adhesion, is non-irritating to the skin, and can be adjusted to fit the shape of the vulva for a tight seal. After urine is produced, two angled guide blocks inside the sleeve direct the urine from the inner wall of the collection cover 31 to the flow guide 1, and then into the flow tube 2, effectively preventing urine accumulation and further reducing the possibility of leakage.
[0014] like Figures 1 to 5 As shown, the outer side of the collection cover 31 is provided with six fitting straps 34, which are evenly divided into three groups. The outer wall of the flow guide cover 1 is equipped with two straps 35 for binding the child's legs. The ends of the two straps 35 that do not contact the flow guide cover 1 are equipped with locking straps 36. The inner walls of the two straps 35 are provided with insertion slots 37 that are adapted to the locking straps 36.
[0015] The above-mentioned solution features Velcro fasteners on the outside of the locking strap 36 and the binding strap 35. Multiple sub-Velcro fasteners are provided on the locking strap 36 to allow for fixation according to the different leg sizes of children, enhancing the device's adaptability. The six binding straps 34 are divided into three groups, enabling the collection cover 31 to be tightly fitted to the girl's vulva from different angles, comprehensively improving the stability of the fit and effectively preventing the collection cover 31 from shifting due to the child's movements, thereby reducing the risk of leakage. Simultaneously, the two binding straps 35 and their corresponding locking straps 36 can be securely wrapped around the child's legs via the insertion slots 37, further securing the entire urine bag 4. By flexibly adjusting the binding tightness, it can fit the thickness of the child's thighs, ensuring that the urine bag 4 does not shake during the child's daily activities, greatly improving its stability during use.
[0016] like Figures 1 to 5 As shown, the locking strap 36 and the binding strap 35 are fixed together by Velcro. The bottom of the drainage tube 2 is connected to the urine bag 4. The urine bag 4 is made of medical plastic and has scale markings on its outer wall for observing the amount of urine inside.
[0017] The above solution employs the following: the adhesive tape 34 is made of a special material that has good adhesion without irritating children's delicate skin, and can be precisely adjusted according to the shape of the vulva, so that the flexible adhesive sleeve 32 fits the vulva tightly and comfortably. The flexible adhesive sleeve 32, made of medical-grade silicone, is soft and skin-friendly, and will not cause pressure or friction damage to the skin, thus improving the comfort of children wearing it. The two oblique guide blocks on the inner wall of the collection cover 31 are cleverly designed to accurately guide urine to the diversion cover 1 after it is produced, and then flow into the diversion tube 2, preventing urine from splashing or accumulating in the collection cover 31, ensuring the efficiency and smoothness of urine collection, further reducing the risk of leakage, and providing strong support for accurate urine collection. This helps medical staff to diagnose the condition more accurately based on the urine situation.
[0018] The working principle of this utility model: First, for girls, align the collection cover 31 with the vulva and use three sets of six adhesive straps 34 to tightly attach the collection cover 31 to the vulva from different angles. Adjust the position to make it stable and comfortable. Secure the flexible adhesive sleeve 32 to both sides of the vulva with the adhesive straps 34, ensuring a tight fit. Wrap the two binding straps 35 around the child's thighs. Depending on the thigh thickness, use the multiple sub-Velcro on the locking strap 36 to cooperate with the male and female Velcro on the outside of the binding strap 35, adjust the tightness, and securely lock it with the insertion slot 37. Then, when the girl urinates, the urine is guided to the guide cover 1 through the inclined guide block 33 on the inner wall of the collection cover 31, and then flows into the urine bag 4 through the guide tube 2. Medical staff or parents can regularly observe and record the urine volume through the scale markings on the outer wall of the urine bag 4 to provide a basis for diagnosis. Finally, after use, unfasten the Velcro and insertion slot 37, remove the urine bag 4, and properly dispose of and replace it.
