Description

Technical Field

[0001] The present invention relates to the technical field of urine sample collection, and specifically to a 24-hour urine sample collection container. Background Art

[0002] Urine protein specimens are mainly used to examine the protein content in a patient's urine. This quantity can reflect the severity of glomerular function impairment to a certain extent and help preliminarily judge whether renal function is damaged.

[0003] When collecting, an appropriate container needs to be prepared, usually a plastic bucket with a lid and a capacity of about 4000 ml. Since the concentration of each urination is different, the urine volume cannot be reduced arbitrarily, nor can a specified number of milliliters of urine be extracted each time. In order to detect all the proteins in the urine and more comprehensively understand the filtration function of the kidneys, the test results obtained by collecting 24-hour urine are the most accurate.

[0004] However, in actual use, patients with chronic interstitial nephritis will have symptoms of urine concentration disorder, manifested as polyuria and large urine volume. The 24-hour urine volume exceeds 3500 - 4000 ml. Therefore, the retention container is large in volume and not easy to carry. When going out, it can only be collected temporarily and then poured into the retention container when returning to the hospital or home, which is also inconvenient for submission for inspection. Summary of the Invention

[0005] The purpose of the present invention is to provide a 24-hour urine sample collection container. Through the first tank body, the second tank body, the connecting pipe, etc., after urine enters the first tank body and the second tank body, under the transmission of the internal pressure of the urine, the water pressure inside the first tank body and the second tank body is equal, so that the urine can maintain a balanced state under the action of gravity, and the urine can be separated proportionally inside the first tank body and the second tank body. Then, the connecting pipe between the first tank body and the second tank body is closed by the adjusting mechanism, and the second drain pipe and the first drain pipe at the bottom ends of the first tank body and the second tank body are opened, so that the smaller portion of urine is discharged into the collection tank through the first drain pipe for collection, and the larger portion of urine is discharged out of the cavity through the second drain pipe. Compared with the completely collected urine sample, the obtained urine sample is reduced in proportion, reducing the amount of urine that needs to be retained. Therefore, only a retention container with a smaller volume is required, which is convenient to carry around, and the error in the protein content per milliliter of the urine sample is extremely small, without affecting the accuracy of the detection, thus solving the problems in the background art.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. For a 24-hour urine sample collection container provided by the present invention, through the first tank body, the second tank body, the connecting pipe, etc., after urine enters the first tank body and the second tank body, under the transmission of the internal pressure of the urine, the water pressure inside the first tank body and the second tank body is equal. Thus, the urine can maintain a liquid level balance state under the action of gravity, and each injection of urine can be distributed in the first tank body and the second tank body according to a fixed ratio. Then, by the adjusting mechanism, the connecting pipe between the first tank body and the second tank body is closed, and the second drain pipe and the first drain pipe at the bottom of the first tank body and the second tank body are opened, so that the smaller portion of urine is discharged into the collection tank through the first drain pipe for collection, while the larger portion of urine is discharged out of the cavity through the second drain pipe. In this way, compared with the urine sample collected completely, the obtained urine sample is reduced in proportion, the amount of urine to be retained is reduced, so only a smaller volume of retention container is needed, which is convenient to carry around, and the error of the protein content per milliliter of the urine sample is extremely small, without affecting the accuracy of the detection.

[0029] 2. For a 24-hour urine sample collection container provided by the present invention, through the sampling mechanism, etc., medical staff can insert a straw into the sampling channel and extend it to the liquid inlet hole, so that it contacts the bottom of the midstream urine, and obtain the midstream urine inside the collection tank for detection, thereby reducing the influence of xylene and sediment on the measurement result. The position of the through hole can be adjusted according to the position of the midstream urine. When adjusting, the waterproof rubber strip provided can move together and always fit the through grooves on both sides to avoid leakage.

[0030] 3. For a 24-hour urine sample collection container provided by the present invention, through the opening and closing mechanism, etc., as urine enters, the closing sleeve gradually rises under the drive of the hollow floating ball. After the closing sleeve moves, urine can enter the liquid medicine storage groove formed on the surface of the installation rod through the through hole formed on the outer wall of the installation cavity and contact the xylene in the liquid medicine storage groove. The xylene can be added according to the volume of urine inside the collection tank. And because xylene is a toxic substance, using this method can enable patients not to add xylene by themselves and avoid excessive addition of xylene from damaging the urine sample.

Specific implementation mode

[0045] 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.

[0046] Please refer to Figures 1 - 13 , a 24-hour urine sample collection container, including a cavity 11, a cover body 12 and a collection tank installation cavity 13. A cover body 12 is rotatably fixed at the top end of the cavity 11, a collection tank installation cavity 13 is fixedly installed below the cavity 11, a detachable first tank body 21 is installed inside the cavity 11, and a second tank body 22 is arranged on one adjacent side of the first tank body 21. A liquid injection pipe 23 is fixedly installed at the top ends of the first tank body 21 and the second tank body 22. A connecting pipe 24 communicating with each other is arranged on the outer walls of one adjacent side of the first tank body 21 and the second tank body 22. A first drain pipe 26 and a second drain pipe 27 are respectively installed at the bottom ends of the first tank body 21 and the second tank body 22, and the second drain pipe 27 penetrates through to the outer wall of the first tank body 21;

[0047] Ball valves 25 are arranged at the middle positions of the connecting pipe 24, the first drain pipe 26 and the second drain pipe 27, and all three ball valves 25 are controlled to open and close through an adjusting mechanism;

[0048] A collection tank 28 is fixedly installed inside the collection tank installation cavity 13, and the first drain pipe 26 is inserted into the top end of the collection tank 28. A sampling mechanism is arranged on one side of the outer wall of the first drain pipe 26;

[0049] An opening and closing mechanism is arranged at the bottom end of the inner wall of the first drain pipe 26, and a preservative is stored in the opening and closing mechanism;

[0050] Please refer to Figure 3 、 4 and 5. After opening the cover body 12, urine is injected into the interior of the liquid injection tube 23 and guided into the interiors of the first tank body 21 and the second tank body 22 through the liquid injection tube 23. Since the first tank body 21 and the second tank body 22 are connected by a connecting pipe 24 at the lower part, under the action of gravity, the first tank body 21 and the second tank body 22 can maintain the liquid level horizontal. Each time the injected urine can be distributed in the first tank body 21 and the second tank body 22 according to a fixed ratio. Then, rotate the adjusting mechanism so that the adjusting mechanism closes the connecting pipe 24 between the first tank body 21 and the second tank body 22 while opening the second drain pipe 27 and the first drain pipe 26 at the bottom ends of the first tank body 21 and the second tank body 22, so that the smaller portion of urine is discharged into the interior of the collection tank 28 through the first drain pipe 26 for collection, and the larger portion of urine is discharged out of the cavity 11 through the second drain pipe 27. Compared with the urine sample collected completely, the obtained urine sample is reduced in equal proportion, reducing the amount of urine that needs to be retained. Therefore, only a smaller volume of retention container is required, which is convenient to carry around, and the error of the protein content per milliliter of the urine sample is extremely small, without affecting the detection accuracy.

[0051] Please refer to Figure 4 、 9 、10 and 11. Among them, the adjusting mechanism includes a movable cavity 31 fixedly installed on the outer wall of the cavity 11, and a rotating rod 32 is rotatably arranged in the middle of the movable cavity 31. The two ends of the rotating rod 32 penetrate through the outer wall of the movable cavity 31 and are connected with a rotating knob 33;

[0052] An installation plate 34 is sleeved on the surface of the rotating rod 32 below the connecting pipe 24, and one side of the outer wall of the installation plate 34 is connected with the inner wall of the movable cavity 31. The installation plate 34 is arranged in an inverted L shape composed of a horizontal part and a vertical part. A first conical wheel 35 is rotatably arranged on the vertical part of the installation plate 34, and a second conical wheel 36 is rotatably arranged at the top of the horizontal part. The second conical wheel 36 meshes with the first conical wheel 35, and the first conical wheel 35 is penetrated by the rotating rod 32 in the middle. The top of the second conical wheel 36 is connected with the adjusting part of the ball valve 25 arranged on the connecting pipe 24;

[0053] Two first transmission wheels 37 are respectively sleeved and installed on the outer walls of the rotating rod 32 on both sides of the installation plate 34. The adjusting parts of the ball valves 25 arranged on the first drain pipe 26 and the second drain pipe 27 are installed with second transmission wheels 38, and the two first transmission wheels 37 respectively mesh with the corresponding second transmission wheels 38;

[0054] After the urine is injected into the interiors of the first tank body 21 and the second tank body 22, when controlling the ball valves 25 installed on the communication pipe 24, the first drain pipe 26, and the second drain pipe 27, by rotating the knob 33, the knob 33 drives the first conical wheel 35 to rotate under the restriction of the mounting plate 34 through the rotating rod 32. The first conical wheel 35 can drive the second conical wheel 36 to rotate, so that the second conical wheel 36 can drive the ball valve 25 installed on the communication pipe 24 to close;

[0055] At the same time, the rotating rod 32 drives the two first transmission wheels 37 to rotate. The two first transmission wheels 37 respectively drive the ball valves 25 installed on the first drain pipe 26 and the second drain pipe 27 to open through the two second transmission wheels 38.

[0056] In order to enable the adjusting mechanism to be disassembled and reused, the movable cavity 31 is set to be semi-circular. An annular groove matching the movable cavity 31 is opened on the front surface of the cavity 11. The movable cavity 31 can be removed from the annular groove opened on the front surface of the cavity 11, so as to achieve the purpose of multiple reuse.

[0057] In order to improve the stability of the movable cavity 31 after installation, two sliding grooves 51 are opened at the top end of the inner wall of the annular groove opened on the front surface of the cavity 11. At the position corresponding to the sliding grooves 51 at the top end of the movable cavity 31, a sliding rail 52 that cooperates with the sliding grooves 51 is integrally formed;

[0058] Threaded grooves are provided at both the bottom end of the movable cavity 31 and the bottom end of the inner wall of the annular groove opened on the front surface of the cavity 11. The movable cavity 31 and the cavity 11 are fixed by meshing with the threads provided at the top of the collection tank installation cavity 13 through the threaded grooves;

[0059] When the movable cavity 31 is inserted into the annular groove opened on the front surface of the cavity 11, the movable cavity 31 can drive the sliding rail 52 to insert into the inside of the sliding groove 51. The sliding groove 51 cooperates with the sliding rail 52 to fix the position of the movable cavity 31. The threaded grooves provided at the bottom end of the movable cavity 31 and the front surface of the cavity 11 can be combined completely. Then, rotate and push the collection tank installation cavity 13, so that the collection tank installation cavity 13 can drive the collection tank 28 to be fixedly installed below the movable cavity 31 and the cavity 11. The movable cavity 31, the cavity 11, and the collection tank installation cavity 13 cooperate with each other to complete the fixed installation.

[0060] Please refer to Figure 4 and Figure 9 For the process that the movable cavity 31 drives the sliding rail 52 to insert into the inside of the sliding groove 51, in order that the second conical wheel 36 can be connected to the ball valve 25 installed on the communication pipe 24, a clamping groove 41 is opened at the bottom end of the adjusting part of the ball valve 25 provided on the communication pipe 24. At the top end of the second conical wheel 36, a clamping block 42 that is engaged with the clamping groove 41 is integrally formed;

[0061] When the movable cavity 31 is inserted into the annular groove formed on the front-end surface of the cavity 11, the second conical wheel 36 can drive the clamping groove 41 to engage with the clamping block 42 installed below the ball valve 25 provided on the connecting pipe 24, so that the torque generated when the second conical wheel 36 rotates can be transmitted to the ball valve 25 through the clamping groove 41 and the clamping block 42 to control the opening and closing of the ball valve 25.

[0062] Please refer to Figure 1 、 10 and 11. To facilitate the discharge of the excess urine inside the first tank body 21, an extension pipe 61 is sleeved and installed on the surface of the second drain pipe 27, and a mounting frame 62 is connected and arranged on the outer wall of the extension pipe 61. A rack 63 is fixedly installed at the top of the mounting frame 62. The rack 63 is located below the second transmission wheel 38 installed on the adjusting part of the ball valve 25 on the second drain pipe 27, and the second transmission wheel 38 meshes with the rack 63;

[0063] When the rotary knob 33 drives the two first transmission wheels 37 to rotate through the rotating rod 32, and drives the second transmission wheel 38 to rotate to open the ball valve 25 through the first transmission wheels 37, the second transmission wheel 38 on the side close to the rack 63 can drive the engaged rack 63 to translate, so that the rack 63 can drive the extension pipe 61 to move on the surface of the second drain pipe 27 through the mounting frame 62. The extension pipe 61 can penetrate through the movable cavity 31 and the outer wall of the cavity 11 and extend outward, facilitating the pouring of urine into the sewer pipe.

[0064] Please refer to Figure 6 , wherein, the sampling mechanism includes a rotating cavity 71 integrally formed on the outer wall of the collection tank 28, and a liquid inlet hole 74 communicating with the collection tank 28 is opened in the middle of the rotating cavity 71;

[0065] Guide wheels 72 are rotatably arranged at the four corners of the inner wall of the rotating cavity 71. Sealing strips 73 are sleeved and installed on the surfaces of the four guide wheels 72. Straight groove holes are opened on the outer wall surfaces of the rotating cavity 71, the liquid inlet hole 74 and the collection tank installation cavity 13. The inner and outer sides of the sealing strip 73 are closely attached to the straight groove holes opened on the surfaces of the rotating cavity 71 and the liquid inlet hole 74 respectively;

[0066] A sampling channel 75 is integrally formed on the outer wall of the sealing strip 73, and the sampling channel 75 penetrates through the straight groove holes opened on the surfaces of the rotating cavity 71 and the collection tank installation cavity 13 respectively. A straw can be inserted into the sampling channel 75 to suck out the sample in the liquid inlet hole 74;

[0067] Since patients with chronic interstitial nephritis may experience acid-base imbalance, the pH value of urine tends to be acidic, making it prone to crystal or flocculent precipitates. The xylene added to prevent urine deterioration has a different density from urine, and its density is less than that of urine, so it will float on the upper layer in urine. After the collected urine has undergone sedimentation and stratification for a period of time, it has reached a relative equilibrium state. Stirring may disrupt this balance and lead to inaccurate measurement results. Therefore, when sampling is required, medical staff can insert a pipette into the sampling channel 75 and extend it to the liquid inlet hole 74 to contact the bottom of the middle-section urine, obtaining the middle-section urine inside the collection tank 28 for testing, thereby reducing the impact of xylene and precipitates on the measurement results. When the suction position needs to be adjusted, by pushing the sampling channel 75, the sampling channel 75 drives the sealing strip 73 to move under the guidance of the four guide wheels 72 and the restriction of the rotating cavity 71 and the liquid inlet hole 74. The position of the sampling channel 75 can be adjusted, and the sealing strip 73 can always be sealed to prevent leakage;

[0068] To facilitate penetration of the suction position, the collection tank installation cavity 13, the collection tank 28, the rotating cavity 71, and the sealing strip 73 can all be made of transparent materials.

[0069] Please refer to Figure 7 and Figure 12 , in order to quantitatively add xylene according to the urine volume inside the collection tank 28, an installation cavity 81 is integrally formed in the middle of the bottom end of the collection tank 28, and a number of through holes are equidistantly and circumferentially formed on the surface of the installation cavity 81. A sealing sleeve 82 is fitted and sleeved on the surface of the installation cavity 81, and a number of hollow floating balls 83 are equidistantly and circumferentially arranged on the outer wall surface of the sealing sleeve 82;

[0070] An installation rod 84 is penetrated through the middle of the bottom ends of the collection tank installation cavity 13 and the collection tank 28, and the installation rods 84 can all be inserted into the interior of the installation cavity 81. A number of liquid medicine storage grooves 85 are arranged at equal intervals on the outer wall surface of the installation rod 84;

[0071] When the installation rod 84 needs to be installed, by inserting the installation rod 84 into the xylene solvent, the dissolved xylene can remain inside the liquid medicine storage grooves 85. Then, the liquid medicine storage grooves 85 are vertically inserted into the interior of the installation cavity 81 and fixed. When urine is injected, the buoyancy generated by the urine can drive the sealing sleeve 82 to gradually rise through the hollow floating balls 83. After the sealing sleeve 82 moves, urine can enter the liquid medicine storage grooves 85 formed on the surface of the installation rod 84 through the through holes formed on the outer wall of the installation cavity 81 and contact the xylene inside the liquid medicine storage grooves 85. The xylene can be added in accordance with the volume of urine inside the collection tank 28. And since xylene is a toxic substance, using this method can enable patients not to add xylene by themselves and avoid excessive addition of xylene from damaging the urine sample.

[0072] Please refer toFigure 8 , 12 and 13, in order to prevent the closing sleeve 82 from opening by itself when installing the installation rod 84, two connecting rods 91 are provided at the top end of the inner wall of the closing sleeve 82, and a limiting block 92 is integrally formed at the bottom end of the connecting rod 91;

[0073] Two arc-shaped limiting grooves 93 corresponding to the positions of the connecting rods 91 are opened at the top end of the installation cavity 81, and a limiting plate 94 is integrally formed at the top end of the limiting groove 93. A through hole gradually narrowing from one side to the other side is opened on the surface of the limiting plate 94, and an arc-shaped adjusting hole 95 is opened at the bottom end of the limiting groove 93;

[0074] Two pins 96 are integrally formed at the top end of the installation rod 84 corresponding to the positions of the two adjusting holes 95. A slot 97 that cooperates with the pins 96 is opened in the middle of the bottom end of the limiting block 92, and the pins 96 can pass through the adjusting holes 95 and be inserted into the inside of the slot 97;

[0075] Before the installation rod 84 is inserted into the installation cavity 81, the closing sleeve 82 drives the limiting block 92 to be fitted inside the limiting groove 93 through the connecting rod 91, and the limiting block 92 is located on the smaller side of the through hole opened on the surface of the limiting plate 94. Under the cooperation of the limiting plate 94 and the limiting groove 93, the limiting block 92 cannot be moved out of the limiting groove 93. Therefore, the position of the closing sleeve 82 cannot be changed, and the closing sleeve 82 can always be in a closed state;

[0076] After the installation rod 84 is inserted into the installation cavity 81, the installation rod 84 can drive the pins 96 to pass through the adjusting holes 95 and be inserted into the slots 97 opened at the bottom end of the limiting block 92. Then, rotate the installation rod 84 so that the installation rod 84 drives the limiting block 92 to rotate inside the limiting groove 93 through the pins 96 and the slots 97. The limiting block 92 moves to the larger side of the through hole opened on the surface of the limiting plate 94 under the guidance of the limiting groove 93. The limiting groove 93 cannot cooperate with the limiting plate 94 to limit the position of the limiting block 92. When urine is injected into the collection tank 28, under the action of buoyancy, the closing sleeve 82 can drive the limiting block 92 to move out of the limiting groove 93, and the closing sleeve 82 can be used normally.

[0077] In order to improve the limiting effect of the limiting groove 93 and the limiting plate 94 on the limiting block 92, the inner wall diameter of the larger side of the arc-shaped through hole opened on the surface of the limiting plate 94 is the same as the outer wall diameter of the limiting block 92, and the inner wall diameter of the smaller side is the same as the outer wall diameter of the connecting rod 91.
