Description

Technical Field

[0001] This invention relates to the field of medical and nursing equipment technology, and in particular to a urine collection device for newborn care. Background Technology

[0002] Newborns have immature immune systems and are at high risk of urinary tract infections. Therefore, urine collection and analysis are crucial for their early health monitoring. Collected urine samples undergo laboratory tests such as routine urinalysis and urine culture to assess urinary tract health and ensure normal newborn development.

[0003] However, neonatal urination is involuntary and irregular, often requiring external urine collection devices in clinical practice. Existing products are mostly designed based on gravity flow principles. In actual use, due to the infant's frequent changes in position and activity, urine backflow often occurs, leading to sample contamination or loss and resulting in low collection efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a urine collection device for newborn care that can prevent urine backflow, thereby improving urine collection efficiency.

[0005] The objective of this invention is achieved by the following technical solution: a urine collection device for newborn care, comprising: a diaper, a urine collection assembly, a ureter and a urine storage bag;

[0006] The diaper has a skin-friendly layer that comes into contact with the baby's skin;

[0007] The urine collection assembly includes an annular positioning seat, a first wrapping structure, and a second wrapping structure. The annular positioning seat is disposed on the skin-friendly layer. The first wrapping structure is disposed on the annular positioning seat and has a first root and a first wrapping ring. The first root and the first wrapping ring are sequentially connected along the direction close to the infant's skin. The first root has a guide channel that penetrates the wall thickness of the diaper. The inner diameter of the first wrapping ring is larger than the inner diameter of the first root. The first wrapping ring is used to wrap the penis of a male infant or to conform to the vulva of a female infant. The second wrapping structure is disposed around the outer periphery of the first wrapping structure and has a second root and a second wrapping ring. The second root and the second wrapping ring are sequentially connected along the direction close to the infant's skin. The inner diameter of the second wrapping ring is larger than the inner diameter of the second root, and one side of the second wrapping ring conforms to the infant's skin.

[0008] The urine storage bag is located on the side facing away from the skin-friendly layer. The urine outlet of the drainage channel, the ureter and the urine collection port of the urine storage bag are connected in sequence. The urine storage bag is provided with a sampling port, which connects the inside and outside of the urine storage bag.

[0009] Furthermore, the first wrapping ring includes a plurality of first valve flaps, which are distributed at intervals around the axis of the flow channel, and a first separation groove is provided between two adjacent first valve flaps. The cross-sectional area of ​​the first valve flaps gradually decreases in the direction away from the first root.

[0010] Furthermore, the second wrapping ring includes a plurality of second valve discs, which are distributed at intervals around the axis of the flow channel, and a second separation groove is provided between two adjacent second valve discs. The cross-sectional area of ​​the second valve discs gradually increases in the direction away from the second root.

[0011] Furthermore, any one of the first separation tanks is located between two adjacent second separation tanks.

[0012] Furthermore, the first wrapping structure also includes a plurality of reinforcing ribs made of polymer hydrogel fibers, one of which is located on the side of one of the first valve flaps facing away from the infant's skin, so that when the reinforcing ribs become wet and hard, the first valve flaps tend to compress the flow channel.

[0013] Furthermore, the annular positioning seat has a water-absorbing groove that extends horizontally away from the baby's skin.

[0014] Furthermore, the annular positioning seat also includes a plurality of limiting grooves, which are disposed on the annular flange of the annular positioning seat. The plurality of limiting grooves are distributed at intervals around the annular flange, and one of the limiting grooves can cooperate with one of the second valve discs.

[0015] Furthermore, the first valve disc is provided with a plurality of flexible protrusions, which are evenly distributed on the skin-friendly surface of the first valve disc.

[0016] Furthermore, the urine collection device for newborn care also includes a fecal isolation pad, which is disposed on the skin-friendly layer. The fecal isolation pad includes a buttock support portion and an isolation portion, which is located between the buttock support portion and the urine collection assembly. The isolation portion is impregnated with pH detection solution.

[0017] Furthermore, the urine collection device for neonatal care also includes a flow-damping valve, which is a duckbill valve. The inlet end of the flow-damping valve is connected to the ureter, and the outlet end of the flow-damping valve is connected to the urine collection port of the urine storage bag.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Based on the first wrapping structure disposed on the annular positioning seat, the first wrapping structure has a first root and a first wrapping ring, the first root and the first wrapping ring being sequentially connected along the direction close to the infant's skin, the first root having a drainage channel that penetrates the wall thickness of the diaper; the first wrapping structure is mounted on the annular positioning seat, and as a preferred embodiment, the first root can be made of a relatively stiff material (e.g., hard rubber) to provide stable structural support; while the first wrapping ring is made of a more flexible material (e.g., medical silicone rubber) to ensure a comfortable fit. The drainage channel is located at the first root and is used to drain urine. Since the inner diameter of the first wrapping ring is larger than the inner diameter of the first root, the first wrapping ring forms a "flared" structure. For male infants, this flared shape has a guiding function, allowing the male infant's penis to enter the first wrapping ring along its inner wall and be wrapped by it; while for female infants, the first wrapping ring can fit against the female infant's vulva. It is easy to see that regardless of whether the user is a male or female infant, the first swaddle ring can cover the skin of the infant's genital area, preventing urine from spilling when it flows back. After the infant changes position, through gravity and the guidance of the first swaddle ring, the backflowing urine can flow back into the drainage channel at the base.

[0020] 2. Based on the second wrapping structure surrounding the first wrapping structure, the second wrapping structure has a second root and a second wrapping ring. The second root and the second wrapping ring are connected sequentially along the direction close to the baby's skin. The inner diameter of the second wrapping ring is larger than the inner diameter of the second root, and one side of the second wrapping ring is in contact with the baby's skin. The second wrapping ring structure has a similar structure to the first wrapping structure, but its function is not exactly the same. A medical-grade hypoallergenic adhesive area (protected by release paper at the factory) can be provided at the end of the second wrapping ring. When putting on a diaper, medical staff tear off the release paper and stick the second wrapping ring to the baby's skin, which can make the entire urine collection assembly more firmly pressed against the baby's body. To ensure effective sealing coverage, the length of the second wrapping ring is longer than that of the first wrapping ring. The second wrapping structure can intercept urine that may overflow from the edge of the first wrapping ring at the first time, retaining the urine in the gap between the first and second wrapping rings. When the infant's posture changes, the intercepted urine can flow back to the first encapsulation ring under the guidance of gravity and the change in body position, and eventually enter the urine collection bag through the diversion channel, avoiding urine waste and thus improving collection efficiency.

[0021] 3. Because the urine collection bag is located on the side opposite to the skin-friendly layer, when the diaper is worn by the infant, the urine collection bag faces the medical staff, making it convenient for the medical staff to observe the urine volume and perform sampling operations at any time without having to turn or move the infant. At the same time, since the urine collection bag is located on the outside of the diaper, it can effectively avoid direct compression of the urine collection bag when the infant is lying on his back or side, which not only prevents the bag from rupturing due to prolonged pressure, but also improves the comfort of the infant when wearing the collection device.

When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 6 As shown, a preferred embodiment of the present invention provides a urine collection device for newborn care, comprising: a diaper 1, a urine collection assembly 2, a ureter 4, and a urine storage bag 5.

[0033] The diaper 1 has a skin-friendly layer 11 that contacts the baby's skin. It can be understood that the diaper 1 carries the other components of the urine collection device. After the medical staff puts the diaper 1 on the baby, the skin-friendly layer 11 faces and contacts the baby's skin.

[0034] The urine collection assembly 2 includes an annular positioning seat 21, a first wrapping structure 22, and a second wrapping structure 23. The annular positioning seat 21 is disposed on the skin-friendly layer 11. The first wrapping structure 22 is disposed on the annular positioning seat 21 and has a first root 221 and a first wrapping ring 222. The first root 221 and the first wrapping ring 222 are connected sequentially along the direction close to the baby's skin. The first root 221 has a drainage channel 3 that penetrates the wall thickness of the diaper 1. The first wrapping ring 222... The inner diameter of the first wrapping ring 222 is larger than the inner diameter of the first root 221. The first wrapping ring 222 is used to wrap the penis of a male infant or to fit the vulva of a female infant. The second wrapping structure 23 is arranged around the outer periphery of the first wrapping structure 22. The second wrapping structure 23 has a second root 231 and a second wrapping ring 232. The second root 231 and the second wrapping ring 232 are connected sequentially in the direction close to the infant's skin. The inner diameter of the second wrapping ring 232 is larger than the inner diameter of the second root 231. One side of the second wrapping ring 232 fits against the infant's skin.

[0035] It is understood that when this device is worn, due to the natural curling of the diaper 1, the annular positioning seat 21 located on the skin-friendly layer 11 will face the baby's skin. The outer contour of the annular positioning seat 21 is similar to the contour of the baby's genitals. Medical staff can adjust the diaper 1 with both hands to make the annular positioning seat 21 roughly aligned with the baby's genitals. Based on the first wrapping structure 22 located on the annular positioning seat 21, the first wrapping structure 22 has a first root 221 and a first wrapping ring 222. The first root 221 and the first wrapping ring 222 are connected sequentially in the direction close to the baby's skin. The first root 221 has a guide channel 3, which penetrates the wall thickness of the diaper 1. The first wrapping structure 22 is installed on the annular positioning seat 21. As a preferred option, the first root 221 can be made of a relatively stiff material (such as hard rubber) to provide stable structural support; while the first wrapping ring 222 needs to have good extensibility, so a more flexible material (such as medical-grade silicone rubber) is used to ensure a comfortable fit. A drainage channel 3 is located at the first root 221 and is used to drain urine. Since the inner diameter of the first wrapping ring 222 is larger than the inner diameter of the first root 221, the first wrapping ring 222 forms a "funnel" structure. For male infants, this funnel shape acts as a guide, allowing the penis to enter and be enveloped by the first wrapping ring 222 along its inner wall. For female infants, the first wrapping ring 222 fits snugly against the vulva. It is clear that regardless of whether the infant is male or female, the first wrapping ring 222 covers the skin of the infant's genitals, preventing urine from overflowing during backflow. After the infant changes position, through gravity and the guidance of the first wrapping ring 222, the backflowing urine can flow back into the drainage channel 3 of the first root 221.

[0036] The second wrapping structure 23 surrounds the first wrapping structure 22. The second wrapping structure 23 has a second root 231 and a second wrapping ring 232, which are sequentially connected along the direction close to the infant's skin. The inner diameter of the second wrapping ring 232 is larger than the inner diameter of the second root 231, and one side of the second wrapping ring 232 adheres to the infant's skin. The second wrapping ring 232 has a structure similar to the first wrapping structure 22, but its function is not entirely the same. A medical-grade hypoallergenic adhesive area (protected by release paper at the factory) can be provided at the end of the second wrapping ring 232. When wearing the diaper 1, medical personnel tear off the release paper and attach the second wrapping ring 232 to the skin area where the infant's genitals are located, allowing the entire urine collection assembly 2 to be more securely pressed against the infant's body. To ensure effective sealing, the second wrapping ring 232 is longer than the first wrapping ring 222, thereby preventing urine from leaking out of the second sealing structure. It should be noted that when the user is a female infant, the second wrapping ring 232 is attached to the first wrapping ring 222, and together with the first wrapping ring 222, they fit snugly against the infant's genitals to prevent urine leakage. The second wrapping structure 23 can intercept any urine that may overflow from the edge of the first wrapping ring 222, retaining the urine in the gap between the first wrapping ring 222 and the second wrapping ring 232. When the infant's posture changes, the intercepted urine can flow back to the first wrapping ring 222 under the guidance of gravity and the change in body position, and finally enter the urine collection bag 5 through the guide channel 3, avoiding urine waste and thus improving collection efficiency.

[0037] The urine storage bag 5 is located on the side facing away from the skin-friendly layer 11. The urine outlet of the drainage channel 3, the ureter 4, and the urine collection port of the urine storage bag 5 are connected in sequence. The urine storage bag 5 has a sampling port 51, which connects the inside and outside of the urine storage bag 5. Because the urine storage bag 5 is located on the side facing away from the skin-friendly layer 11, when the diaper 1 is worn by the infant, the urine storage bag 5 faces the medical staff, making it convenient for them to observe urine volume and perform sampling operations at any time without turning or moving the infant. At the same time, since the urine storage bag 5 is located on the outside of the diaper 1, it effectively avoids direct compression of the infant when lying supine or on its side, preventing potential rupture of the bag due to prolonged pressure and improving the overall comfort of the infant. After the infant urinates, the urine flows sequentially through the drainage channel 3 and the ureter 4, and is finally stored in the urine storage bag 5. Medical staff can use sampling tools such as syringes to extract urine samples from the sampling port 51 for clinical testing.

[0038] The working principle of this invention is as follows: Diaper 1 is worn on the infant's body as a wearable carrier. The urine collection component 2 is fixed to the skin-friendly layer 11 by the annular positioning seat 21, ensuring initial alignment with the infant's genitals. Medical personnel press the side of diaper 1 facing away from the skin-friendly layer 11, guiding the first wrapping structure 22 to wrap around the infant's genitals. Specifically, the first wrapping ring 222 of the first wrapping structure 22 can wrap around the penis of a male infant or conform to the vulva of a female infant, providing versatility. Urine, under the influence of gravity and guided by the inner wall of the first wrapping ring 222, flows into the drainage channel 3 of the first root 221. The second wrapping ring 232 of the second wrapping structure 23 is tightly adhered to the skin around the genitals using medical adhesive, forming a secondary wrap. When the user is a female infant, the second wrapping ring 232 is attached to the first wrapping ring 222, working together with the first wrapping ring 222 to conform to the female infant's genitals, preventing urine leakage. In the event of urine leakage, the second wrapping structure 23 can effectively intercept urine overflowing from the first wrapping ring 222: the gap between it and the first wrapping ring 222 serves as a temporary urine storage area. When the infant changes position, the intercepted urine can flow back to the first wrapping ring 222 under the guidance of gravity and positional changes and be directed to the drainage channel 3. The collected urine flows through the drainage channel 3, through the ureter 4, and into the urine collection bag 5 located outside the diaper 1. This avoids the risk of the urine collection bag 5 being ruptured by the infant's body and also allows its sampling port 51 to directly face medical personnel, facilitating aseptic sampling using syringes and other tools.

[0039] like Figures 3 to 5As shown, preferably, the first wrapping ring 222 includes a plurality of first valve flaps 2221, which are distributed at intervals around the axis of the guide channel 3. A first separation groove 2222 is provided between two adjacent first valve flaps 2221, and the cross-sectional area of ​​the first valve flaps 2221 gradually decreases in the direction away from the first root 221. It can be understood that for male infants, when the penis enters, the plurality of independent first valve flaps 2221 slightly expand outward in accordance with the outer radial direction of the penis, forming a wrapping channel that fits the shape of the penis better, avoiding uneven pressure on the penis. For female infants, each first valve flap 2221 can conform to the irregular contour curve of the female infant's vulva, and at the same time, the first valve flaps 2221 can press against the second wrapping ring 232. Based on the fact that the cross-sectional area of ​​the first valve flap 2221 gradually decreases in the direction away from the first root 221, and the end of the first valve flap 2221 is thinner and softer, with a gradient change in softness from the first root 221 to the end of the first valve flap 2221, the first valve flap 2221 can bend and deform more naturally and smoothly when squeezed, further optimizing the fit with the infant's genitals. Based on the fact that a first separation groove 2222 is provided between two adjacent first valve flaps 2221, this first separation groove 2222 forms a channel for urine return. When the infant changes position, under the action of gravity, the urine temporarily stored in the second wrapping ring 232 can flow along the outer surface of the first valve flap 2221 through these first separation grooves 2222 back into the area wrapped by the first wrapping ring 222.

[0040] like Figure 3 , Figure 4 and Figure 6 As shown, preferably, the second wrapping ring 232 includes a plurality of second valve flaps 2321, which are spaced apart around the axis of the flow channel 3. A second separation groove 2322 is provided between two adjacent second valve flaps 2321, and the cross-sectional area of ​​the second valve flaps 2321 gradually increases in the direction away from the second root 231. Based on the spaced distribution of the plurality of second valve flaps 2321 around the axis of the flow channel 3 and the second separation groove 2322 provided between two adjacent second valve flaps 2321, these second separation grooves 2322 allow each second valve flap 2321 to move independently. When the infant's body twists, the second valve flaps 2321 can adapt to the stretching and wrinkling changes of the skin, thereby always maintaining the sealing state of the second wrapping ring 232 on the skin area where the outer contour of the genitals is located. Based on the fact that the cross-sectional area of ​​the second valve flap 2321 gradually increases in the direction away from the second root 231, when it is in contact with the baby's skin, the second valve flap 2321 spreads outward and the area of ​​the second valve flap 2321 in contact with the baby's skin gradually increases, which can stably support the second root 231 and the first root 221 located at the center of the urine collection assembly 2, and keep the baby's urethra always facing the drainage channel 3.

[0041] like Figure 3 and Figure 4 As shown, preferably, any one of the first separation grooves 2222 is located between two adjacent second separation grooves 2322. It can be understood that the first valve flap 2221 and the second valve flap 2321 are distributed alternately. For male infants, the first wrapping ring 222 wraps around the penis, and the first valve flap 2221 and the second valve flap 2321 do not fit together, so that urine leaking from the first separation groove 2222 can be intercepted by the second valve flap 2321, and will not flow directly outside the second valve flap 2321. For female infants, the second valve flap 2321 directly covers and seals the first separation groove 2222 located below from above, blocking the path of urine leakage from the first separation groove 2222.

[0042] like Figure 3 and Figure 5 As shown, preferably, the first wrapping structure 22 further includes a plurality of reinforcing ribs 6, which are made of polymer hydrogel fibers. One of the reinforcing ribs 6 is located on the side of one of the first valve flaps 2221 facing away from the infant's skin, so that when the reinforcing rib 6 becomes wet and hard, the first valve flap 2221 tends to compress the drainage channel 3. Because the reinforcing rib 6 is made of polymer hydrogel fibers, in a dry state, the reinforcing rib 6 is soft and does not affect the normal deformation of the first valve flap 2221; once urine leaks out and wets the reinforcing rib 6, the polymer hydrogel fibers quickly absorb moisture and harden, thereby providing additional radial support for the corresponding first valve flap 2221. For male infants, this allows the first wrapping ring 222 to wrap the penis more tightly; for female infants, it allows the first valve flap 2221 to more stably conform to the vulva contour.

[0043] like Figure 3 and Figure 4 As shown, preferably, the annular positioning seat 21 has an absorbent groove 211 that extends horizontally away from the infant's skin. It is understood that the surface of the absorbent groove 211 is made of medical non-woven fabric, and the absorbent groove 211 is mainly used to absorb urine leaking from the second valve 2321.

[0044] like Figure 3As shown, preferably, the annular positioning seat 21 further includes a plurality of limiting grooves 213. The limiting grooves 213 are disposed on the annular flange 212 of the annular positioning seat 21, and the plurality of limiting grooves 213 are distributed at intervals around the annular flange 212. One of the limiting grooves 213 can cooperate with one of the second valve flaps 2321. When the second valve flap 2321 is in contact with the baby's skin, each second valve flap 2321 can be firmly embedded in a corresponding limiting groove 213, which enhances the structural stability when subjected to changes in the baby's posture, prevents the second valve flap 2321 from loosening and shifting, and ensures that the second wrapping ring 232 can always maintain a sealed state.

[0045] like Figure 3 and Figure 4 As shown, preferably, the first valve flap 2221 is provided with a plurality of flexible protrusions 7, which are evenly distributed on the skin-friendly surface of the first valve flap 2221. It can be understood that the flexible protrusions 7 can adapt to the slight undulations of the infant's skin surface, filling in uneven areas and forming multiple local sealing points. This avoids the risk of leakage caused by lateral overflow of liquid under the sealing surface, ensuring that urine is collected and guided into the drainage channel 3.

[0046] like Figure 1 As shown, preferably, the urine collection device for neonatal care further includes a fecal isolation pad 8, which is disposed on the skin-friendly layer 11. The fecal isolation pad 8 includes a buttock support portion 81 and an isolation portion 82. The isolation portion 82 is located between the buttock support portion 81 and the urine collection assembly 2, and is impregnated with a pH detection solution. The buttock support portion 81 can receive the feces excreted by the infant, and the isolation portion 82 constitutes a physical barrier that can effectively prevent feces from invading or contaminating the urine collection assembly 2, thereby ensuring the purity of the urine sample and avoiding distortion of test results due to sample contamination. Based on the pH detection solution impregnated with the isolation portion 82, when the excreted feces come into contact with the pH detection solution-impregnated isolation portion 82, the isolation portion 82 can produce a specific color change according to the pH of the feces. By observing whether the isolation portion 82 shows a color change, medical personnel can determine whether the feces may invade the urine collection assembly 2, and thus replace the collection device in a timely manner.

[0047] like Figure 2As shown, preferably, the urine collection device for neonatal care further includes a flow-damping valve 9, which is a duckbill valve. The inlet end of the flow-damping valve 9 is connected to the ureter 4, and the outlet end of the flow-damping valve 9 is connected to the urine collection port of the urine storage bag 5. It can be understood that when urine flows in from the ureter 4 under gravity, the flexible "duckbill" structure inside the flow-damping valve 9 is opened by fluid pressure, allowing urine to pass smoothly and enter the urine storage bag 5. Once the flow stops or the urine storage bag 5 is squeezed or experiences reverse pressure due to changes in the infant's position, this pressure will cause the "duckbill" structure to close tightly, preventing backflow of urine stored in the urine storage bag 5 and ensuring stable storage of urine within the urine storage bag 5.
