Description

Technical Field

[0001] The present invention relates to the technical field of urine collection, in particular to a urine collector for neonatal testing. Background Art

[0002] A urine collector is a medical device or tool used to collect human urine samples. It can be widely used in medical care, scientific research, physical examinations and other fields. In the medical care process, collecting urine from newborns is an important and meticulous task. It is of great significance for diagnosing the health status of newborns, monitoring growth and development, and early detection of potential diseases. To ensure the accuracy and effectiveness of urine samples, before collection, you should carefully check whether the packaging of the collection device is intact to ensure that it is not damaged or contaminated. Use warm water and a soft cotton cloth or paper towel to gently clean the newborn's perineum to remove possible dirt and secretions to reduce the risk of contamination of the urine sample. At the same time, the cleaning action should be gentle and avoid using detergents containing irritating chemicals to avoid damaging the delicate skin of the newborn. The entire collection process should strictly follow the principles of aseptic operation to avoid contact between hands, clothing or other objects and urine samples.

[0003] During the actual collection process, it is usually necessary to stick a urine collector to the perineum of the newborn. In order to detect the health status or growth and development of the newborn, it may be necessary to continuously test the newborn's urine. Since newborns lack the ability to express themselves, and the daily urination time and frequency cannot be accurately controlled or predicted, it is also impossible to manually observe the newborn's urination status in real time throughout the day, especially at night, when newborns may urinate multiple times. Existing newborn urine collection devices are usually equipped with only one urine storage bag. The urine discharged by the newborn multiple times may be mixed in the urine collection device. The mixed urine may not be accurately detected, making it impossible to accurately evaluate the health status or growth and development of the newborn. For this reason, we propose a urine collector for newborn testing. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-11The present invention provides a technical solution: a urine collector for neonatal testing, comprising a collection bucket 2 made of elastic material, a sealing pad 3 for adhering to the skin of the neonate fixedly mounted on one end of the collection bucket 2, and a flexible connecting tube 4 fixedly mounted on the other end, a sealing ring 1 fixedly mounted on the collection bucket 2, a flexible and breathable material fixing plate 5 fixedly mounted on the sealing ring 1, two leg straps 13 for binding to the legs fixedly mounted on the fixing plate 5, each leg strap 13 is closed and adjusted in size by a second Velcro 14, and each leg strap 13 is fixedly mounted It is equipped with several anti-slip pads 15 made of breathable material, a waist strap 11 is provided above the fixing plate 5, the waist strap 11 is closed and the size is adjusted by a first Velcro 12, two first connecting belts 9 are slidably installed on the waist strap 11 through a connecting ring 10, each first connecting belt 9 is installed on the fixing plate 5 through a fixing member 7, and two second connecting belts 16 are slidably installed on the waist strap 11 through a connecting ring 10. One end of each second connecting belt 16 is slidably installed on the corresponding leg strap 13 through the connecting ring 10. The first connecting belt 9 and the second connecting belt 16 are both made of elastic material. , a number of elastic members 6 are fixedly installed on the fixing plate 5, and each fixing member 7 is provided with a number of limiting holes 8 for limiting the elastic member 6, and the limiting holes 8 correspond to the elastic members 6 one by one. After aligning the collecting bucket 2 with the perineum of the newborn, stick the sealing pad 3 on the skin of the newborn, and then tie the two leg straps 13 to the two legs of the newborn, and adjust the size of the leg straps 13 through the second Velcro 14 to prevent excessive restraint on the legs of the newborn. At the same time, the anti-slip pad 15 can prevent the leg straps 13 from loosening and falling off. Then align the limiting holes 8 on the fixing member 7 with the elastic member 6 on the fixing plate 5, The elastic member 6 is deformed, and then the elasticity of the elastic member 6 itself causes it to recover, limiting the fixing member 7 so that the fixing member 7 is fixed to the fixing plate 5. Since most newborns wear open-crotch pants, the first connecting belt 9 and the second connecting belt 16 are pulled out from the crotch, and the waist belt 11 is tied to the waist of the newborn. The size of the waist belt 11 is adjusted by the first Velcro 12 to prevent excessive restraint on the newborn's waist. By fixing the leg straps 13 to the waist belt 11, the fixing plate 5 and the collecting bucket 2 can be stably adhered to the perineum of the newborn, which is convenient for collecting urine from the newborn.

[0033] A plurality of anti-return plates 19 arranged in a ring are fixedly installed in the collecting hopper 2. Each anti-return plate 19 is made of elastic material and is arranged at an angle. An elastic ureter 20 is fixedly installed at one end of the connecting tube 4. A one-way valve 21 for preventing urine reflux is fixedly installed at both the upper and lower ends of the ureter 20. A flexible liquid storage bag 17 is fixedly installed at the lower end of the ureter 20. A plurality of collection pieces 26 for collecting urine are fixedly installed on the outer wall of the ureter 20. Each collection piece 26 is made of elastic material and has a lower end. A collection bag 18 is fixedly installed at each end. Since the urine in the collection bag 18 is for testing, the capacity of the collection bag 18 is usually small, and the urine produced by the newborn each time can fill it. The ureter 20 is provided with a plurality of liquid inlets 25 for allowing urine to enter the collection member 26. Two elastic rotating plates 22 are rotatably installed in the ureter 20. An elastic liquid partition plate 23 is fixedly connected between the two rotating plates 22. A guide plate 24 is fixedly installed on the liquid partition plate 23 for allowing urine to enter the liquid inlet 25. The guide plate 24 is also made of elastic material. Since the connecting tube 4 is made of flexible material, the urine collected by the collecting hopper 2 always flows downward under the action of gravity and flows into the ureter 20 through the connecting tube 4. Since the return plates 19 are arranged in a ring and are all inclined, when the urine passes through the return plates 19, the return plates 19 will deform, and the urine will flow into the connecting tube 4 from the gaps between the adjacent return plates 19. When the urine is about to flow into the collecting hopper 2 in the reverse direction, the return plates 19 will deform in the reverse direction, and the adjacent return plates 19 will gather together. The gap between them gradually closes, and the urine is prevented from flowing back into the collecting bucket 2. A large part of the urine flowing into the ureter 20 will be guided by the guide plate 24 and will flow into the corresponding collection piece 26 through the corresponding liquid inlet 25. Another small part will flow into the liquid storage bag 17 through the gap between the guide plate 24 and the inner wall of the ureter 20. At the same time, the partition plate 23 prevents urine from entering other liquid inlets 25. After the collection piece 26 and the collection bag 18 at its lower end are filled with the urine required for testing, all the urine will enter the liquid storage bag 17 below.

[0034] A support plate 28 is fixedly installed in each collection piece 26, and a floating plate 30 for blocking the liquid inlet 25 is slidably installed in each collection piece 26. A sliding column 29 for limiting the floating plate 30 is fixedly installed on the support plate 28. The floating plate 30 is provided with a vent hole 31. An expansion groove 27 is provided in each collection piece 26, and an expansion block 35 that expands after absorbing liquid is fixedly installed in each expansion groove 27. A liquid baffle 33 for blocking the expansion groove 27 is slidably installed in each collection piece 26, and each liquid baffle 33 is located above the floating plate 30. A liquid inlet hole 32 is provided on each floating plate 30 to facilitate urine to enter the expansion groove 27. A blocking plug 34 for blocking the liquid inlet hole 32 is fixedly installed. Each blocking plug 34 is wedge-shaped to facilitate its entry into the liquid inlet hole 32. A plurality of second blocks 38 for limiting the guide plate 24 are slidably installed on the inner wall of the ureter 20. The second blocks 38 correspond one-to-one to the liquid inlet 25, and an elastic ring 39 is fixedly connected between each second block 38 and the inner wall of the ureter 20. A limiting groove 41 is provided in each collecting member 26, and a push rod 42 pushed by the floating plate 30 is slidably installed in each limiting groove 41. A connecting rope 40 is fixedly installed on the inner wall of each limiting groove 41, and one end of each connecting rope 40 is fixedly connected to the corresponding second block 38 On the inner wall of the ureter 20, a plurality of first stops 36 for limiting the guide plate 24 are also slidably installed. The first stops 36 correspond to the second stops 38 one by one and are respectively located on both sides of the guide plate 24. An elastic column 37 is fixedly connected between each first stop 36 and the inner wall of the ureter 20. One side of the guide plate 24 is set to be a wedge shape that matches the first stop 36. After the urine enters the collection part 26, it will not enter the expansion tank 27 due to the obstruction of the liquid baffle 33, and will flow into the collection bag 18. After the collection bag 18 is full, the urine will be stored in the collection part 26, and then the floating plate 30 will float on the liquid surface due to the limitation of the sliding column 29, and the liquid baffle 33 will be lifted. When the collecting piece 26 is fully stored, the liquid baffle 33 will retract into the collecting piece 26, and at this time the liquid inlet hole 32 on the float plate 30 will be located at the entrance of the expansion tank 27. Urine enters the expansion tank 27 through the liquid inlet hole 32. The expansion block 35 expands after absorbing the urine. After filling the expansion tank 27, it will push the float plate 30 to move toward the liquid inlet 25. The end of the float plate 30 will enter the liquid inlet 25. At the same time, the blocking plug 34 blocks the liquid inlet hole 32, so that urine no longer enters the collecting piece 26 and the collecting bag 18 through the liquid inlet 25. The urine collected in the collecting bag 18 can be sealed to prevent it from mixing with the urine when the newborn urinates again.

[0035] A connecting rod 43 is rotatably mounted on the lower end of the upper one-way valve 21, and a connecting piece 44 is rotatably mounted on one end of the connecting rod 43. A sliding groove 45 for limiting the connecting piece 44 is provided on the inner wall of the ureter 20. A first wedge block 46 is fixedly mounted on the connecting piece 44. A plurality of second wedge blocks 47 cooperating with the first wedge blocks 46 are fixedly mounted on the lower end of the upper rotating plate 22. The second wedge blocks 47 correspond to the collecting pieces 26 one by one, and an elastic guide plate 48 is fixedly mounted on each second wedge block 47. When the floating plate 30 moves into the liquid inlet 25, it will push the push rod 42 to slide along the limiting groove 41, and the connecting rope 40 will also be bent. Since one end of the connecting rope 40 is fixedly connected The second stopper 38 will be pulled to move toward the inner wall of the ureter 20, and the elastic ring 39 will be compressed. The second stopper 38 will release the limit on the guide plate 24. When urine flows into the ureter 20, the upper one-way valve 21 will be deformed downward. The push of the connecting rod 43 will cause the connecting piece 44 to drive the first wedge block 46 to move downward. The guide plate 48 will be deformed during the downward movement of the first wedge block 46, and will not hinder the movement of the first wedge block 46. It can be reset by its own elasticity. When the newborn has finished urinating, the one-way valve 21 will be restored to its original shape by its own elasticity. The connecting rod 43 and the connecting piece 44 are reset. During the upward movement of the first wedge block 46 driven by the connecting piece 44, the inclined surface of the first wedge block 46 cooperates with the inclined surface of the second wedge block 47 through the guidance of the guide plate 48, so that the second wedge block 47 drives the rotating plate 22 and the liquid partition plate 23 to rotate, and the guide plate 24 is rotated to the next liquid inlet 25. When the newborn urinates again, the urine will enter the next collection piece 26 and its corresponding collection bag 18. During the rotation of the guide plate 24, after the wedge surface on one side contacts the corresponding first stopper 36, the first stopper 36 will move toward the inner wall of the ureter 20, and the elastic column 37 will be deformed, and the guide plate 24 will be rotated to the next liquid inlet 25. After the flow plate 24 passes the first stopper 36, the elasticity of the elastic column 37 resets the first stopper 36 and limits the guide plate 24 again. Since the ureter 20 is made of elastic material, if no urine enters the corresponding collection piece 26, the second stopper 38 will retract. Even if the ureter 20 is squeezed to deform the upper one-way valve 21, the guide plate 24 will be limited by the second stopper 38, and the guide plate 48 will be deformed. The inclined surface of the first wedge block 46 cannot match the inclined surface of the second wedge block 47, causing the rotating plate 22 to rotate, preventing the neonate from squeezing the ureter 20 and driving the rotating plate 22 to rotate. Only after the neonate urinates can the next collection piece 26 collect urine.

[0036] Specifically, when it is necessary to collect urine from a newborn, first align the collecting bucket 2 with the perineum of the newborn, and stick the sealing pad 3 on the skin of the newborn, then tie the two leg straps 13 to the two legs of the newborn, and adjust the size of the leg straps 13 through the second Velcro 14 to prevent excessive restraint on the legs of the newborn, then align the upper limit hole 8 of the fixing member 7 with the elastic member 6 on the fixing plate 5 to deform the elastic member 6, and then the elasticity of the elastic member 6 itself causes it to recover, limit the fixing member 7 so that the fixing member 7 is fixed on the fixing plate 5, pull the first connecting belt 9 and the second connecting belt 16 out of the crotch, and tie the waist strap 11 to the waist of the newborn, and adjust the size of the waist strap 11 through the first Velcro 12 to prevent excessive restraint on the waist of the newborn. The urine collected in the collecting bucket 2 always flows downward under the action of gravity and flows into the ureter 20 through the connecting tube 4. When the urine passes through the return plate 19, the return plate 19 will be deformed, and the urine flows into the connecting tube 4 from the gap between the adjacent return plates 19. When the urine is about to flow into the collecting bucket 2 in the reverse direction, the return plate 19 will be deformed in the reverse direction, and the adjacent return plates 19 will be gathered together, and the gap between them will gradually close, and the urine will be organized to flow back into the collecting bucket 2 and into the ureter 20. A large part of the urine will flow into the corresponding collection piece 26 through the corresponding liquid inlet 25 under the guidance of the guide plate 24, and another small part will flow into the liquid storage bag 17 through the gap between the guide plate 24 and the inner wall of the ureter 20. At the same time, the liquid partition plate 23 prevents urine from entering it. After the urine enters the collection part 26, it will not be able to enter the expansion tank 27 due to the obstruction of the liquid baffle 33, and will flow into the collection bag 18. After the collection bag 18 is full, the urine will be stored in the collection part 26, and then the float 30 will float with the liquid surface due to the limitation of the slide column 29, and push the liquid baffle 33 upward. When the collection part 26 is full, the liquid baffle 33 will retract into the collection part 26, and at this time the liquid inlet hole 32 on the float 30 will be located at the entrance of the expansion tank 27. Urine enters the expansion tank 27 through the liquid inlet hole 32. The expansion block 35 expands after absorbing the urine. After filling the expansion tank 27, it will push the float 30 to move toward the liquid inlet 25, and the end of the float 30 will enter the liquid inlet 25. At the same time, through the baffle The blocking of the liquid inlet hole 32 by the stopper 34 prevents urine from entering the collection member 26 and the collection bag 18 through the liquid inlet 25. When the floating plate 30 moves toward the liquid inlet 25, it will push the push rod 42 to slide along the limiting groove 41, and the connecting rope 40 will also be bent. Since one end of the connecting rope 40 is fixedly connected to the inner wall of the limiting groove 41, and the other end is fixedly connected to the second stopper 38, the second stopper 38 will be pulled and move toward the inner wall of the ureter 20, and the elastic ring 39 will be compressed. The second stopper 38 will release the restriction on the guide plate 24. When urine flows into the ureter 20, the upper one-way valve 21 will be deformed downward. Through the push of the connecting rod 43, the connecting member 44 will drive the first wedge block 46 to move downward. When the newborn has finished urinating,The one-way valve 21 will recover its deformation through its own elasticity and drive the connecting rod 43 and the connecting piece 44 to reset. During the upward movement of the first wedge block 46 driven by the connecting piece 44, the inclined surface of the first wedge block 46 will cooperate with the inclined surface of the second wedge block 47 through the guidance of the guide plate 48, so that the second wedge block 47 drives the rotating plate 22 and the liquid partition plate 23 to rotate, and the guide plate 24 is rotated to the next liquid inlet 25. When the newborn urinates again, the urine will enter the next collection piece 26 and its corresponding collection bag 18. During the rotation of the guide plate 24, after the wedge surface on one side contacts the corresponding first stopper 36, the first stopper 36 will move toward the inner wall of the ureter 20, and the elastic column 37 is deformed. After the guide plate 24 passes the first stopper 36, the elasticity of the elastic column 37 resets the first stopper 36 and re-limits the guide plate 24. Since the ureter 20 is made of elastic material, if no urine enters the corresponding collection member 26, the second stopper 38 will retract. Even if the ureter 20 is squeezed and the upper one-way valve 21 is deformed, the guide plate 24 is limited by the second stopper 38, and the guide plate 48 will deform. The inclined surface of the first wedge block 46 cannot match the inclined surface of the second wedge block 47, causing the rotating plate 22 to rotate. This prevents the newborn from squeezing the ureter 20 and driving the rotating plate 22 to rotate. Only after the newborn urinates can the next collection member 26 collect urine.
