Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a novel comfortable urine bag for children. Background Technology
[0002] In clinical practice, indwelling urine bags for children are assistive tools designed for specific medical needs. They are mainly used to help children who are unable to urinate independently or who need urine monitoring to collect urine. They are primarily used for children with urinary incontinence, children who need catheterization after surgery or illness, or children who need urine monitoring.
[0003] The existing new comfortable indwelling bags for children still have some shortcomings in actual use:
[0004] 1. After the child urinates in the urine bag, because the baby is very active, if the urine is not removed in time, when the baby moves his / her legs, it is easy to squeeze the urine inside the urine bag. At this time, the urine is not blocked and is easy to flow back and spill out.
[0005] 2. The existing urine bag's container part and the part connected to the child's body cannot be separated for use. Each time the urine bag is removed, a new one needs to be replaced, and it needs to be repeatedly adhered and fixed to the child's body. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to seal urine, easy backflow, spillage of urine, and the need to replace the urine bag with a new one and re-adhere it to the child's body when it is removed. Therefore, this invention proposes a new type of comfortable urine bag for children.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A novel comfortable indwelling bag for children includes a silicone pad and a container bag. A catheterization chamber is fixedly connected to one side of the silicone pad. A first connecting ring is fixedly connected to the outlet of the catheterization chamber. An adhesive ring is fixedly connected to the inlet of the container bag. A second connecting ring is fixedly connected to one side of the adhesive ring. The outer wall of the first connecting ring and the inner wall of the second connecting ring are both provided with threaded grooves, and the first connecting ring and the second connecting ring are threadedly connected through the two threaded grooves.
[0009] In one possible design, a connecting plate is fixedly connected inside the first connecting ring, and connecting shafts are fixedly connected to both sides of the connecting plate. A baffle is provided inside the first connecting ring, and the baffle is rotatably sleeved on the outer wall of the two connecting shafts. The diameter of the baffle is larger than the diameter of the connecting plate.
[0010] In one possible design, a silicone ring is fixedly connected to one side of the adhesive ring, and a limiting ring is fixedly connected to one end of the silicone ring. The silicone ring wraps around the abutment ring, and the limiting ring is attached to one side of the abutment ring.
[0011] In one possible design, the first connecting ring has a semi-circular groove, and the baffle is rotated within the semi-circular groove.
[0012] In one possible design, the first connecting ring has a retaining ring on the side near the catheterization chamber, and one side of the baffle contacts the retaining ring.
[0013] In one possible design, a pressure-sensitive adhesive is provided on one side of the silicone pad, and a water-resistant rubber ring is provided on another side of the silicone pad, with the water-resistant rubber ring fixed to the inner wall of the through hole of the silicone pad.
[0014] In one possible design, the outer wall of the container bag is marked with scale lines.
[0015] In this application, a silicone pad can be adhered to the area near the child's genitals. Urine enters the first connecting ring through the catheter chamber. The impact of the urine pushes a baffle open via a connecting shaft within a semi-circular groove, allowing the urine to enter the collection bag. After the child finishes urinating, the baffle automatically closes within the first connecting ring due to its weight. When the urine in the collection bag is squeezed back, the urine impacts one side of the baffle, further compressing it within the semi-circular groove to achieve a sealing effect. When it is necessary to remove the urine from the collection bag, it is retracted. The silicone ring on the contact ring allows the second connecting ring to be unscrewed from the threaded groove, separating the container bag from the first connecting ring. After the urine in the container bag is poured out, the container bag can be reconnected to the threaded groove on the outer wall of the first connecting ring via the second connecting ring. The silicone ring can then be unfolded to form a wrap around the first connecting ring, while the limiting ring presses against one side of the contact ring to prevent the silicone ring from automatically rolling up. The silicone ring placed between the second connecting ring and the contact ring can prevent the second connecting ring from falling off the outer wall of the first connecting ring due to the child's leg kicking or body twisting.
[0016] Beneficial effects: In this utility model, the novel comfortable urine bag for children allows the baffle to automatically close within the first connecting ring after the child finishes urinating. When the urine in the bag is squeezed back, the urine impacts from one side of the baffle, causing the baffle to be further squeezed within the semi-circular groove, thereby achieving a sealing effect, effectively preventing urine backflow, and ensuring the accuracy and hygiene of urine collection.
[0017] In this utility model, the novel comfortable urine bag for children has a second connecting ring that can be unscrewed from the threaded groove, separating the container bag from the first connecting ring and allowing the urine in the container bag to be poured out. When the first and second connecting rings are reconnected, the silicone ring can unfold onto the first connecting ring to form a wrap. At the same time, the silicone ring is pressed against the side of the contact ring by the limiting ring, effectively preventing the silicone ring from automatically rewinding. The entire sampling process is simple and convenient to operate, improving the efficiency of use.
[0018] In this invention, the novel comfortable urine bag for children has significant beneficial effects in terms of urine collection, backflow prevention, convenient sampling, and comfortable wearing, bringing great convenience to children and their caregivers. Attached Figure Description

An adhesive ring 11 is fixedly connected to the inlet of the holding bag 1. A second connecting ring 15 is fixedly connected to one side of the adhesive ring 11. The outer wall of the first connecting ring 5 and the inner wall of the second connecting ring 15 are both provided with threaded grooves 13, and the first connecting ring 5 and the second connecting ring 15 are threaded together through the two threaded grooves 13. The silicone pad 2 and the holding bag 1 are connected to the second connecting ring 15 through the adhesive ring 11, and then the second connecting ring 15 is threadedly connected to the first connecting ring 5, and then connected to the urinary catheterization chamber 3, forming a complete indwelling urine bag structure.
[0026] Reference Figure 3 and Figure 4 A connecting plate 7 is fixedly connected inside the first connecting ring 5. Connecting shafts 8 are fixedly connected to both sides of the connecting plate 7. A baffle 9 is provided inside the first connecting ring 5, and the baffle 9 is rotatably sleeved on the outer wall of the two connecting shafts 8. The diameter of the baffle 9 is larger than the diameter of the connecting plate 7. The baffle 9 rotatably sleeved on the outer wall of the two connecting shafts 8 allows the baffle 9 to rotate around the connecting shafts 8. Simultaneously, the larger diameter of the baffle 9 ensures that it effectively blocks urine flow during rotation, preventing backflow of urine.
[0027] Reference Figure 4 A silicone ring 4 is fixedly connected to one side of the adhesive ring 11, and a limiting ring 12 is fixedly connected to one end of the silicone ring 4.
