Description

Technical Field

[0001] The present invention relates to the field of urine collectors, and in particular to a urine specimen collector for baby girls. Background Art

[0002] In order to treat some diseases of infants, such as diagnosing urinary tract infections, nephritis, nephrotic syndrome and other diseases, it is necessary to collect the urine of infants as a sample for testing. For infants, since urination is uncontrollable, it is usually necessary to use a urine collector to be worn by the infant to collect urine. Especially for baby girls, a collector adapted to the shape of the vulva needs to be set up to reduce urine leakage.

[0003] Among them, the front-section urine in the urine sample will wash the urethral orifice when discharged, and may mix with bacteria, secretions or external pollutants. These impurities will change the true composition of the urine and affect the accuracy of the test results. (For example, the resident bacteria in the urethral orifice may be misjudged as pathogenic bacteria of urinary tract infection, and red blood cells may come from urethral mucosal damage rather than urinary system lesions, interfering with the judgment of the source of hematuria). In the prior art, for the collection of urine, it is usually impossible to automatically remove the front-section urine, and there is still room for improvement in how to automatically remove the front-section urine and collect the subsequent urine as a test sample for the current collectors.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a urine specimen collector for baby girls.

[0021] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the urine specimen collector for baby girls includes: a fitting part 1, the fitting part 1 includes a collection cover 11 and a belt assembly 12, the belt assembly 12 is installed on the collection cover 11, and the inner cavity depth of the collection cover 11 gradually deepens; A front-section collection bottle 3, the tube part 33 of the front-section collection bottle 3 is communicated with the collection cover 11 through an infusion tube 2; A connection assembly 5, the connection assembly 5 includes a connecting tube 51 and a connector 52, one end of the connecting tube 51 is communicated with the tube part 33, and the connector 52 is connected to the other end of the connecting tube 51 A middle-section collection bottle 4, the middle-section collection bottle 4 is detachably installed on the connector 52; A valve assembly 6, the valve assembly 6 is used to control the communication state between the connecting tube 51 and the tube part 33, and control the communication state between the tube part 33 of the front-section collection bottle 3 and the bottle part 31.

[0022] The infusion tube 2 is connected to the deeper end of the collection cover 11.

[0023] When in use, the collection cover 11 is placed in contact with the vulva of the baby, and the deeper end faces the anus side of the baby, so that it can have a better urine storage function to avoid direct urine overflow. The collection cover 11 is fixed by the belt assembly 12 to prevent it from separating from the vulva of the baby. When the baby starts to urinate, the urine enters the collection cover 11 and flows into the deeper end. Then, part of the urine enters the front-stage collection bottle 3 through the infusion tube 2. Then, the valve assembly 6 controls the connecting tube 51 to communicate with the tube portion 33 and blocks the tube portion 33. At this time, the urine enters the middle-stage collection bottle 4 through the connecting tube 51 to complete the urine collection, and the urine in the front stage is removed, thus greatly reducing the possible inaccurate detection caused by the flushing of the urethral orifice by the urine in the front stage and the mixing of bacteria, secretions or external contaminants.

[0024] Among them, the collection volume of the urine in the front stage is specifically set according to the age of the baby. For example, the single urine volume of a 2-6-month-old baby is about 10-30 ml, and the single urine volume of a 6-12-month-old baby is about 25-40 ml. Different capacities can be set for different stages. For example, the urine in the front stage is set in the range of 5-10 ml. The present invention is preferably used for older babies, such as those over six months old, with a relatively large single urine volume.

[0025] And when collecting urine, it is preferably to pick up the baby so that the urine can better enter the front-stage collection bottle 3 and the middle-stage collection bottle 4 by gravity through the infusion tube 2.

[0026] The collection cover 11 is made of medical-grade silicone or soft TPE material, etc.

[0027] The bottom end of the collection cover 11 is provided with an assembly head 112 for connecting with the infusion tube 2, and the connection method can be threaded connection, snap connection, etc.

[0028] Please refer to Figure 1 , as a preferred method of this embodiment, the belt assembly 12 includes a plurality of side belts 121 and two Y-shaped belts 122. The plurality of side belts 121 are installed on both sides of the collection cover 11, and the two Y-shaped belts 122 are respectively installed at both ends of the collection cover 11.

[0029] Among them, after the collection cover 11 is placed in contact with the vulva of the baby, the two Y-shaped belts 122 respectively wrap around to the front side and the rear side of the baby's waist. The two side straps of the Y-shaped belt 122 correspondingly bypass along the waist, and the two side straps of the two Y-shaped belts 122 are correspondingly connected to fix the collection cover 11. The side belt 121 can be fixed to the baby's diaper or disposable diaper, and the collection cover 11 is limited by the diaper or disposable diaper to better fit the vulva of the baby without separation.

[0030] Specifically, the side belts 121 are pulled out from both sides of the diaper or incontinence diaper, and then the paired side belts 121 are connected to each other.

[0031] When cooperating with the incontinence diaper or diaper, the infusion tube 2 can pass through the side of the incontinence diaper or diaper, or can correspond to the cutting holes in the incontinence diaper or diaper for the infusion tube 2 to pass through.

[0032] Among them, hook surfaces and loop surfaces of Velcro are correspondingly arranged on the side belts 121 on both sides of the collection cover 11 and fixed by Velcro, or male and female snaps can also be set, etc. Similarly, hook surfaces and loop surfaces of Velcro, or male and female snaps, etc. are correspondingly arranged on the side belts of the two Y-shaped belts 122.

[0033] Please refer to Figure 1 , a sealing flange 111 is arranged on the side of the collection cover 11 that fits the skin.

[0034] Through the sealing flange 111, the fitting area between the edge of the collection cover 11 and the baby's skin can be increased, and the edge tightness can be improved.

[0035] The sealing flange 111 is preferably made of medical-grade silicone.

[0036] Please refer to Figure 3 and Figure 6 , in this embodiment, the front-section collection bottle 3 further includes a conical portion 32, the bottle portion 31 is communicated with the tube portion 33 through the conical portion 32, the valve assembly 6 includes a floating block 61 and an arc-shaped baffle 62, the arc-shaped baffle 62 is installed on the floating block 61, a liquid inlet 63 is opened on the arc-shaped baffle 62, a plurality of support rods 311 are arranged around the inside of the front-section collection bottle 3, the floating block 61 is arranged on the support rods 311, the top end of the arc-shaped baffle 62 fits the inner wall of the tube portion 33 and blocks the liquid inlet end of the connecting tube 51, and the liquid inlet 63 is located below the liquid inlet end of the connecting tube 51.

[0037] During the process of collecting urine, since the initial arc-shaped baffle 62 blocks the liquid inlet 63, urine can only enter the front-section collection bottle 3. When the urine gradually fills the front-section collection bottle 3, as the liquid level of the urine gradually rises, it drives the floating block 61 to gradually move upward, and the floating block 61 drives the arc-shaped baffle 62 to move upward accordingly, so that the liquid inlet 63 gradually coincides with the liquid inlet end of the connecting tube 51. When the floating block 61 abuts against and blocks the top of the conical portion 32, the bottle portion 31 of the front-section collection bottle 3 is filled with urine, and the subsequent urine enters the middle-section collection bottle 4 through the liquid inlet 63 via the connecting tube 51 for collection. Thus, it can automatically collect the front-section urine separately without mixing with the subsequent urine.

[0038] Among them, a horizontal portion is provided at the top of the inner wall of the conical portion 32, so that when the floating block 61 abuts against the top of the conical portion 32, the floating block 61 abuts against the horizontal portion at the top of the inner wall of the conical portion 32, improving the stability during abutment.

[0039] In this embodiment, the number of the support rods 311 is multiple, and in this embodiment, it is three, which are arranged around the inner wall of the front-stage collection bottle 3; The radian of the arc-shaped baffle 62 is adapted to the arc of the pipe portion 33, so that the arc-shaped baffle 62 can fit against the inner wall of the pipe portion 33.

[0040] The volume of the front-stage collection bottle 3 is the volume of the corresponding front-stage urine (5 - 10 ml).

[0041] The floating block 61 can be made of materials with relatively light mass such as plastic and foam.

[0042] In other embodiments, a floating ball can also be used to replace the floating block 61 of the valve assembly 6.

[0043] Please refer to Figure 2 , as a preferred mode of this embodiment, the urine specimen collector for female infants further includes a blocking assembly 7, and the blocking assembly 7 is used to control the communication state of the liquid outlet end of the connecting pipe 51.

[0044] By providing the blocking assembly 7, when the middle-stage collection bottle 4 is filled, the blocking assembly 7 blocks the output end of the connecting pipe 51, which can prevent the last part of the rear-stage urine from entering and can separate the urine at the end; Since the urine at the very end may be mixed with sediments at the bottom of the bladder, etc., it will interfere with the test results for conventional urine tests (such as misjudged as false kidney stones), etc., and the urine at the end is suitable for detecting bladder diseases, lower urinary tract infections, etc., and the middle-stage urine is suitable for conventional tests, such as evaluating kidney function (such as urine protein and creatinine tests); screening for metabolic diseases (diabetes, gout); detecting urinary tract infections.

[0045] In this embodiment, the preferred collection volume of the middle-stage urine is (10 - 25 ml), and the excess urine is the urine at the end (5 - 15 ml). Of course, when the urine is less, the urine at the end is ignored and enough urine is collected for sample testing.

[0046] Please refer to Figure 4 and Figure 7 , as an alternative mode of this embodiment, the blocking assembly 7 includes a floating ball and two first positioning blocks 74. The two first positioning blocks 74 are installed on both sides of the floating ball. The floating ball is vertically slidably installed inside the connector 52 through the first positioning blocks 74 and is suspended below the connecting pipe 51. There are gaps between the floating ball and both the connecting pipe 51 and the liquid inlet 41 of the middle-stage collection bottle 4.

[0047] When the urine gradually fills the middle-section collection bottle 4, the urine gradually lifts the floating ball, causing the floating ball to abut against the liquid outlet solid end of the connecting pipe 51, thereby blocking the liquid outlet end of the connecting pipe 51 and isolating it from the urine in the final section.

[0048] Wherein, two sliding rods 511 are arranged on the inner wall of the connector 52, and two first positioning blocks 74 are correspondingly sleeved on the sliding rods 511 to form a sliding assembly. And a end cap 512 is arranged at the bottom end of the sliding rod 511 for supporting the first positioning block 74, thereby realizing the support for the floating ball. By arranging the sliding rod 511, the floating ball can accurately block the liquid outlet pipe of the connecting pipe 51.

[0049] Please refer to again Figure 4 , as an alternative way of this embodiment, the floating ball includes a lower floating part 71, an upper floating part 72, and an insertion shaft 73. The insertion shaft 73 is installed on the lower floating part 71, and the lower floating part 71 is inserted into the upper floating part 72 through the insertion shaft 73. The first positioning block 74 is installed on the upper floating part 72. Second positioning blocks 75 are installed on both sides of the lower floating part 71, and the two second positioning blocks 75 are correspondingly located below the two first positioning blocks 74; The urine specimen collector for female infants further includes a separation assembly 8, and the separation assembly 8 is used to separate the upper floating part 72 and the lower floating part 71.

[0050] After the middle-section collection bottle 4 has collected the urine, at this time the upper floating part 72 abuts against the liquid outlet end of the connecting pipe 51. The separation assembly 8 separates the upper floating part 72 and the lower floating part 71. The separation assembly 8 pushes up the upper floating part 72 to cause it to deform and squeeze into the connecting pipe 51. Thus, after the middle-section collection bottle 4 is separated from the connector 52, it can prevent the urine located inside the connecting pipe 51 from flowing out onto the hands of the staff or the ground, etc.

[0051] And the lower floating part 71 falls on the liquid inlet 63 at the top of the middle-section collection bottle 4. At this time, the staff can slightly press the lower floating part 71 to make its bottom end squeeze into the liquid inlet 63 to be used as the lid of the middle-section collection bottle 4. When pressing, a tissue or gloves can be used to separate the hand from the lower floating part 71 for pressing.

[0052] Please refer to Figure 4 and Figure 5 , the number of the separation assemblies 8 is two. The separation assembly 8 includes a connecting rod 81 and a driving block 82. The two connecting rods 81 are both rotatably installed on the inner wall of the connector 52 and are located on both sides of the floating ball. And the bottom ends of the two connecting rods 81 are inserted into the top of the middle-section collection bottle 4. The two driving blocks 82 are correspondingly installed on the connecting rods 81. The cross-section of the driving block 82 is triangular. The middle-section collection bottle 4 is threadedly connected to the connector 52; When the float is in contact with the liquid outlet of the connecting pipe 51 , the height of the narrow end of the driving block 82 is located between the first positioning block 74 and the second positioning block 75 .

[0053] After the middle collecting bottle 4 has collected the urine, the float ball abuts against the liquid outlet of the connecting tube 51. At this time, the middle collecting bottle 4 is twisted clockwise to separate it from the connecting head 52. During the twisting process, the middle collecting bottle 4 drives the two connecting rods 81 to rotate accordingly. The connecting rod 81 drives the tip of the driving block 82 to be inserted between the first positioning block 74 and the second positioning block 75. As the driving block 82 completely passes through the first positioning block 74 and the second positioning block 75, the driving block 82 pushes the first positioning block 74 to move up and pushes the second positioning block 75 to move down, so that the first positioning block 74 and the second positioning block 75 drive the upper floating part 72 and the lower floating part 71 to separate, and at the same time, the upper floating part 72 is squeezed into the liquid outlet end of the connecting tube 51 to achieve the blocking of the connecting tube 51.

[0054] Therefore, the float can be used to seal the liquid outlet end of the connecting tube 51 in one state, greatly reducing the urine at the end from entering the middle collecting bottle 4. During the disassembly of the middle collecting bottle 4, the float can be separated into the upper floating part 72 and the lower floating part 71, which are used as covers to seal the connecting tube 51 and the liquid inlet 41 of the middle collecting bottle 4 respectively.

[0055] In the initial state, the driving block 82 is staggered with the first positioning block 74 and the second positioning block 75. When following the rotation of the front collecting bottle 3, the driving block 82 will follow the rotation and pass through the first positioning block 74 and the second positioning block 75 and act accordingly.

[0056] The tips of the two driving blocks 82 are arranged to face clockwise, so that when the middle collecting bottle 4 is rotated, the two driving blocks 82 can be driven to interact with the corresponding two groups of first positioning blocks 74 and second positioning blocks 75 .

[0057] A threaded tube portion 42 is provided at the top end of the middle section collecting bottle 4, which is threadedly connected to the connecting head 52 through the threaded tube portion 42, wherein the spacing value of adjacent threads is much smaller than the thickness value of the driving block 82. Therefore, when the middle section collecting bottle 4 drives the driving block 82 to rotate and interact with the first positioning block 74 and the second positioning block 75, the distance that the middle section collecting bottle 4 descends relative to the connecting head 52 will not affect the driving block 82 passing through the first positioning block 74 and the second positioning block 75 and interacting with the first positioning block 74 and the second positioning block 75.

[0058] A corresponding insertion hole is provided at the bottom of the floating portion 72 , and the insertion shaft 73 is interference fit with the insertion hole.

[0059] The second positioning block 75 is provided with a through hole 741, and the area of the through hole 741 is larger than that of the end cap 512, so that the second positioning block 75 can pass through the end cap 512 without being blocked by the end cap 512.

[0060] As another alternative of this embodiment, the separating assembly includes a rotating shaft and a rotating block. The rotating shaft penetrates through the connecting head 52 and is located above the threaded pipe portion 42 (reducing the height value of the threaded pipe portion 42). The rotating block is installed at the end of the rotating shaft and is located inside the connecting head 52. When it is necessary to separate the floating upper part 72 and the floating lower part 71, push the rotating shaft to insert the rotating block between the first positioning block 74 and the second positioning block 75, and then rotate the rotating shaft to drive the rotating block to rotate. The two sides of the rotating block act on the first positioning block 74 and the second positioning block 75 respectively to push the first positioning block 74 and the second positioning block 75 to move upward and downward respectively, so as to drive the floating upper part 72 and the floating lower part 71 to separate.

[0061] Please refer to Figure 2 , as an alternative of this embodiment, a sealing plug 312 is detachably installed at the bottom end of the front-stage collection bottle 3.

[0062] Subsequently, the sealing plug 312 can be removed to drain the urine in the front-stage collection bottle 3, pour out the urine in the front-stage collection bottle 3, and then adjust the position of the connecting pipe 51 so that the end urine inside the connecting pipe 51 is poured out through the front-stage collection bottle 3 into the collection container for detection.

[0063] Both the connecting pipe 51 and the infusion pipe 2 are made of flexible hoses.

[0064] Please refer to Figure 2 , a U-shaped sleeve 401 is installed on the middle-stage collection bottle 4, and a plug 301 is installed on the front-stage collection bottle 3. The plug 301 is inserted into the U-shaped sleeve 401.

[0065] The plug 301 and the U-shaped sleeve 401 are in interference fit.

[0066] By providing the U-shaped sleeve 401 and the plug 301, the front-stage collection bottle 3 and the middle-stage collection bottle 4 can be relatively limited in position, which is convenient for placement.

[0067] The working principle of the urine specimen collector for baby girls provided by the present invention is as follows: During use, the collection cover 11 is placed in contact with the vulva of the baby, and the deeper end faces the anus side of the baby, so that a better temporary storage function for urine can be achieved, avoiding direct overflow of urine, and the collection cover 11 is fixed by the belt assembly 12 to prevent separation from the vulva of the baby; When the baby starts to urinate, the urine enters the collection cover 11 and flows into the deeper end, and then part of the urine enters the front-section collection bottle 3 through the infusion tube 2. Then, the valve assembly 6 controls the communication between the connecting tube 51 and the tube part 33 and blocks the tube part 33. At this time, the urine enters the middle-section collection bottle 4 through the connecting tube 51 to complete the collection of urine, and the urine in the front section is removed, thus greatly reducing the possible inaccurate detection caused by the flushing of the urethral orifice by the urine in the front section and the mixing of bacteria, secretions or external pollutants.

[0068] Specifically, during the urine collection process, since the initial arc-shaped baffle 62 blocks the liquid inlet 63, the urine can only enter the front-section collection bottle 3. When the urine gradually fills the front-section collection bottle 3 and the liquid level of the urine gradually rises, it drives the floating block 61 to move upward step by step. The floating block 61 drives the arc-shaped baffle 62 to move upward accordingly, so that the liquid inlet 63 gradually coincides with the liquid inlet end of the connecting tube 51. When the floating block 61 abuts against and blocks the top of the conical part 32, the bottle part 31 of the front-section collection bottle 3 is filled with urine, and the subsequent urine enters the middle-section collection bottle 4 through the liquid inlet 63 by the connecting tube 51 for collection. Thus, it can automatically collect the urine in the front section separately and will not be mixed with the subsequent urine.

[0069] After the middle-section collection bottle 4 collects the urine, the floating ball abuts against the liquid outlet of the connecting tube 51. At this time, turn the middle-section collection bottle 4 clockwise to separate it from the connecting head 52. During the turning process, the middle-section collection bottle 4 drives the two connecting rods 81 to rotate accordingly. The connecting rods 81 drive the tip of the driving block 82 to insert between the first positioning block 74 and the second positioning block 75. As the driving block 82 completely passes through the first positioning block 74 and the second positioning block 75, the driving block 82 pushes the first positioning block 74 upward and pushes the second positioning block 75 downward, so that the first positioning block 74 and the second positioning block 75 drive the upper floating part 72 and the lower floating part 71 to separate. At the same time, the upper floating part 72 squeezes into the liquid outlet end of the connecting tube 51 to block the connecting tube 51.

[0070] And the lower floating part 71 lands on the liquid inlet 63 at the top of the middle-section collection bottle 4. At this time, the staff can slightly press the lower floating part 71 so that its bottom end squeezes into the liquid inlet 63 to be used as the lid of the middle-section collection bottle 4. When pressing, a tissue or gloves can be used to separate the hand from the lower floating part 71 for pressing.

[0071] Thus, the floating ball can be used to block the liquid outlet end of the connecting tube 51 in one state, greatly reducing the entry of the urine at the end section into the middle-section collection bottle 4. During the process of disassembling the middle-section collection bottle 4, the floating ball can be separated into the upper floating part 72 and the lower floating part 71, which are respectively used as lids to block the assembly of the connecting tube 51 and the liquid inlet 41 of the middle-section collection bottle 4.

[0072] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
