Description

Technical Field

[0001] This application relates to the technical field of urology, and particularly relates to a urine sampler for sampling according to requirements. Background Art

[0002] Urine examination is a detection method in medicine. It includes routine urine analysis, detection of formed components in urine (such as urinary red blood cells, white blood cells, etc.), quantitative determination of protein components, urine enzyme determination, etc. Urine examination is of great importance for clinical diagnosis, judging the curative effect and prognosis. All urine specimens should be collected using clean containers.

[0003] In principle, the midstream urine of the first urine after getting up in the morning is selected for urine detection, which is the most accurate. However, for research purposes, sometimes the front urine or the front urine + midstream urine needs to be selected for detection.

[0004] Currently, urine is mainly collected through a urine cup. If midstream urine needs to be collected, it is necessary to urinate first, hold the urine, and then use the urine cup to collect the midstream urine; if front urine needs to be collected, it is necessary to first use the urine cup to collect the front urine, hold the urine, then take away the urine cup, and continue to discharge the remaining urine. This operation method is extremely inconvenient for children or the elderly. Summary of the Invention

[0005] In order to facilitate the collection of required urine, this application provides a urine sampler for sampling according to requirements.

[0006] The urine sampler for sampling according to requirements provided by this application adopts the following technical solutions:

[0007] A urine sampler for sampling according to requirements includes: a urine funnel for docking with the corresponding part of the human body;

[0008] A urine collecting tube for collecting the required urine;

[0009] Converter, within which a urine channel is provided. Along the flow direction of urine, a liquid inlet, a liquid collection port, and a liquid discharge port are sequentially arranged within the converter. The urine funnel and the urine collection tube are installed on the converter. The urine funnel is arranged close to the liquid inlet. A urine collection end is arranged on the outer wall of the converter at the position of the liquid collection port, and the pipe orifice of the urine collection tube is docked with the urine collection end. A front-section urine temporary storage cavity is arranged within the side wall of the converter. A front-section urine inlet communicating the urine channel and the front-section urine temporary storage cavity is opened on the inner wall of the converter. The front-section urine inlet is arranged close to the liquid inlet. A front-section urine opening and closing component for blocking the front-section urine inlet is arranged within the front-section urine inlet. An exhaust pipe is slidably connected to the inner wall of the converter. One end of the exhaust pipe and the urine collection end can extend into the urine collection tube. An exhaust pipe adjusting device capable of adjusting the length of the end portion of the exhaust pipe extending into the urine collection tube is arranged within the converter. The exhaust pipe adjusting device is simultaneously used to control the front-section urine opening and closing component.

[0010] By adopting the above technical solution, the initial state of the urine sampler is set to sample the front-section urine. Urine can enter the converter through the urine funnel and enter the urine collection tube through the liquid collection port. When the urine in the urine collection tube reaches a certain amount, the urine blocks the pipe orifice of the exhaust pipe. At this time, urine cannot continue to enter the urine collection tube, and the urine is discharged through the liquid discharge port. When it is necessary to sample the front-section urine and the middle-section urine, use the exhaust pipe adjusting device to adjust the length of the exhaust pipe extending into the urine collection tube to shorten its length. At this time, the urine collection tube can collect more urine, and then collect the front-section urine and the middle-section urine. When it is necessary to sample the middle-section urine, use the exhaust pipe adjusting device to control the front-section urine opening and closing component, and use the front-section urine opening and closing component to open the front-section urine inlet. At this time, the front-section urine can enter the front-section urine temporary storage cavity through the front-section urine inlet. After the front-section urine temporary storage cavity is full, the middle-section urine continues to flow to the liquid collection port and enters the urine collection tube, and the urine collection tube collects the middle-section urine. After the urine collection tube is full, the urine continues to be discharged from the liquid discharge port to realize the discharge of urine. Before the urine sampler of the present application is used, the exhaust pipe adjusting device can be adjusted according to needs to select the urine to be sampled, and then the person to be sampled directly urinates through the urine sampler, and the urine corresponding to the required urine can be collected. Compared with the urine sampler in the prior art, the urine sampler of the present application has complete functions, can better meet various urine sampling requirements, is convenient for users to use, and is convenient, efficient and fast for urine sampling.

[0011] Optionally, the exhaust pipe adjusting device includes:

[0012] An adjusting rotating tube, rotatably connected to the converter, and the adjusting rotating tube extends along the flow direction of urine;

[0013] An exhaust pipe adjusting rack, fixed on the outer wall of the exhaust pipe;

[0014] An exhaust pipe gear, fixed on the outer periphery of the adjusting rotating tube and meshing with the exhaust pipe adjusting gear.

[0015] By adopting the above technical solution, by rotating and adjusting the rotating pipe, the length of the exhaust pipe extending into the urine collecting pipe can be adjusted. The longer the extension length of the exhaust pipe, the less urine the urine collecting pipe can collect, and thus the amount of urine collected by the urine collecting pipe can be regulated.

[0016] Optionally, the front-urine opening and closing assembly includes:

[0017] A front-urine sealing plug, which is movably sealed in the front-urine inlet;

[0018] A sealing plug fixing rod, which is fixed on the side of the front-urine sealing plug away from the front-urine inlet;

[0019] A rod limiting block, which is fixed on the inner wall of the converter, and the sealing plug fixing rod is slidably connected with the rod limiting block;

[0020] The exhaust pipe adjusting device includes a sealing plug adjusting assembly for adjusting the position of the front-urine sealing plug.

[0021] By adopting the above technical solution, when it is not necessary to separately sample the middle-urine, the front-urine sealing plug blocks the front-urine inlet; when it is necessary to sample the middle-urine, the front-urine sealing plug is moved away by using the sealing plug adjusting assembly, and the front-urine is temporarily stored in the front-urine temporary storage cavity, so that the urine collecting pipe can effectively sample and collect the middle-urine.

[0022] Optionally, the sealing plug adjusting assembly includes:

[0023] A sealing plug adjusting rack, which is fixed on the outer periphery of the sealing plug fixing rod;

[0024] A sealing plug adjusting gear, which is sleeved on the outer periphery of the adjusting rotating pipe and meshes with the sealing plug adjusting gear;

[0025] An adjusting gear limiting member, which is arranged in the adjusting rotating pipe so that when the adjusting rotating pipe rotates, it can drive the sealing plug adjusting gear to rotate or not drive the sealing plug adjusting gear to rotate.

[0026] By adopting the above technical solution, when it is not necessary to separately sample the middle-urine, the amount of front-urine + middle-urine is adjusted by rotating the adjusting rotating pipe; when it is necessary to separately sample the middle-urine, the position of the front-urine sealing plug can be controlled by using the adjusting gear limiting member to meet the sampling requirements. The setting of this solution ensures the selectivity of the sampled urine, is convenient for personnel to operate, and improves the operation convenience.

[0027] Optionally, the adjusting gear limiting member includes:

[0028] A gear limiting wedge block, which is slidably connected with the side wall of the adjusting rotating pipe along the radial direction of the adjusting rotating pipe;

[0029] The push rod is slidably connected to the inner wall of the adjustment rotary tube along the axial direction of the adjustment rotary tube, and one end of the push rod extends out of the converter;

[0030] The push rod limit wedge is fixed at the end of the push rod, and the push rod limit wedge is slidably abutted against the gear limit wedge;

[0031] The wedge reset member is arranged in the adjustment rotary tube for resetting the gear limit wedge to the inside of the adjustment rotary tube.

[0032] By adopting the above technical solution, when it is necessary to adjust the position of the front urine sealing plug, the position of the front urine sealing plug can be controlled by pressing the push rod and then rotating the adjustment rotary tube. At the same time, after the position of the front urine sealing plug is moved to the predetermined position, the adjustment rotary tube can be directly rotated without pressing the push rod, so as to adjust the amount of middle urine to be collected. The application scheme can not only selectively sample the required urine, but also control the amount of urine to be sampled, which can meet both the requirements of sampling types and sampling amounts, and greatly improves the applicable range of the urine collector.

[0033] Optionally, the urine funnel is inserted and matched with the converter.

[0034] By adopting the above technical solution, the urine funnel and the converter can be separately manufactured, which is beneficial to reducing the manufacturing cost. At the same time, it is also beneficial to assemble the urine funnel and the converter together when the urine collector is needed, so as to reduce the transportation cost.

[0035] Optionally, the converter is a tubular member with one end closed and the other end open.

[0036] By adopting the above technical solution, it is ensured that the urine flows along the expected track. At the same time, the closed end can effectively support the exhaust pipe adjusting device and reserve an operation space for convenient operation by personnel.

[0037] Optionally, a baffle is arranged on one side of the inner wall of the converter close to the liquid inlet.

[0038] By adopting the above technical solution, it is beneficial to make the urine flow successively along the liquid inlet, the liquid collecting port and the liquid discharging port, so as to ensure the subsequent selective sampling of urine.

[0039] Optionally, the inner wall of the urine collecting tube is threadedly connected to the outer wall of the urine collecting end.

[0040] By adopting the above technical solution, it is beneficial to disassemble and assemble the urine collecting tube and the converter, so as to facilitate the subsequent recycling of the urine collecting tube and the subsequent detection of urine. Such a setting is also beneficial to making the exhaust pipe extend into the urine collecting tube while ensuring the sealing performance, and controlling the amount of urine that the urine collecting tube can collect by the extending length of the exhaust pipe.

[0041] Optionally, a scale mark is provided on the end face of the converter near the end of the adjusting rotating tube.

[0042] By adopting the above technical solution, the scale mark facilitates personnel to view the amount of urine that the urine collecting tube can collect, and the amount of urine to be collected is controlled by adjusting the rotating tube.

[0043] In summary, the present application includes at least one of the following beneficial technical effects:

[0044] 1. Before the urine collector of the present application is used, the exhaust pipe adjusting device can be adjusted according to requirements to select the urine to be sampled. Then, the person to be sampled can directly urinate through the urine collector, and the urine corresponding to the requirements can be collected. Compared with the urine collectors in the prior art, the urine collector of the present application has complete functions, can better meet various urine sampling requirements, is convenient for users to use, and is convenient, efficient and fast for urine sampling.

[0045] 2. The present application can select the urine to be sampled according to the required urine, and can also select the sampling according to the population to be sampled. For example, children have less urine. When it is necessary to collect the front-segment urine, the length of the exhaust pipe extending into the urine collecting tube can be adjusted to be longer, and the subsequent urine can be discharged through the liquid discharge port. For example, adults have more urine. When it is necessary to collect the front-segment urine, the length of the exhaust pipe extending into the urine collecting tube can be adjusted slightly shorter; it can be seen that on the one hand, the solution of the present application can sample according to the required urine, and on the other hand, it can also select the appropriate sampling amount according to different populations, so as to maximize the accuracy of sampling.

[0058] The embodiment of the present application discloses a urine sampler for sampling according to requirements. Referring to Figure 1 FIG. 1, it includes a urine funnel 10, a urine collection tube 20 and a converter 30. The urine funnel 10 is inserted into the converter 30. The urine funnel 10 is used to introduce urine into the converter 30. The urine collection tube 20 is installed at the bottom end of the converter 30 and is used to collect the urine to be sampled. The converter 30 is used to control the urine sampled according to requirements to meet the sampling needs

[0060] Referring to Figure 2 FIG. 3, a urine channel 310 is provided inside the converter 30. Urine flows along the urine channel 310. Inside the converter 30, a liquid inlet 311, a liquid collection port 312 and a drain port 313 are successively arranged along the flow direction of the urine. The liquid inlet 311 is arranged close to the closed end of the converter 30, and the liquid inlet 311 is opened at the top of the converter 30. The urine funnel 10 is inserted into the liquid inlet 311. There is a certain frictional force between the outer wall of the urine funnel 10 and the inner wall of the liquid inlet 311. After the urine funnel 10 is inserted into the connector, it can maintain a stable position

[0061] At the same time, a baffle 320 is arranged on one side of the inner wall of the converter 30 close to the liquid inlet 311. The setting of the baffle 320 enables the urine to flow along a predetermined trajectory, ensuring that sampling can be selected subsequently

[0062] Referring toFigure 2 A front urine temporary storage chamber 330 is provided in the side wall of the converter 30 near the bottom, and a front urine inlet 331 connecting the urine channel 310 and the front urine temporary storage chamber 330 is provided on the inner wall of the converter 30. The front urine inlet 331 is arranged near the inlet 311, and a front urine opening and closing component 40 for blocking the front urine inlet 331 is arranged in the front urine inlet 331.

[0063] Reference Figure 3 and Figure 4 The front urine opening and closing assembly 40 includes a front urine sealing plug 410, a sealing plug fixing rod 420 and a rod limiting block 430. The front urine sealing plug 410 is movably sealed in the front urine liquid inlet 331, the sealing plug fixing rod 420 is fixed to the top of the front urine sealing plug 410, one side of the rod limiting block 430 is fixedly connected to the inner wall of the converter 30, and one end of the sealing plug fixing rod 420 is slidably connected to the rod limiting block 430.

[0064] Reference Figure 2 When it is necessary to collect the mid-stream urine separately, the front-stream urine inlet 331 can be opened by controlling the position of the front-stream urine sealing plug 410, and the front-stream urine can be temporarily stored in the front-stream urine temporary storage chamber 330, and the mid-stream urine can be collected later using the urine collecting tube 20.

[0065] Reference Figure 2 The liquid collecting port 312 is opened at the bottom of the converter 30, and a urine collecting terminal 340 is provided on the outer wall of the converter 30 and located at the liquid collecting port 312. The urine collecting terminal 340 extends in a direction away from the converter 30. The outer wall of the urine collecting terminal 340 is threadedly connected to the inner wall of the urine collecting tube 20, and the end of the urine collecting terminal 340 extends into the urine collecting tube 20. Urine can enter the urine collecting tube 20 through the liquid collecting port 312 to realize urine sampling and collection.

[0066] Reference Figure 2 The side wall of the converter 30 is slidably connected with an exhaust pipe 350, which slides along the radial direction of the converter 30. One end of the exhaust pipe 350 extends into the converter 30, and the other end of the exhaust pipe 350 passes through the urine collecting end 340 and extends to the outside of the converter 30. The outer wall of the exhaust pipe 350 is movably sealed to the inner wall of the converter 30 to minimize urine leakage through the gap between the exhaust pipe 350 and the converter 30.

[0067] Reference Figure 2 The converter 30 is provided with an exhaust pipe adjusting device 50 capable of adjusting the length of the end of the exhaust pipe 350 extending into the urine collecting tube 20 , and the exhaust pipe adjusting device 50 is also used to control the front urine opening and closing component 40 .

[0068] Reference Figure 2 and Figure 3, the exhaust pipe adjusting device 50 includes an adjusting rotating pipe 510, an exhaust pipe adjusting rack 520, and an exhaust pipe gear 530. The adjusting rotating pipe 510 extends along the axial direction of the converter 30. One end of the adjusting rotating pipe 510 extends outside the closed end of the converter 30. One end of the adjusting rotating pipe 510 is rotatably connected to the closed end of the converter 30, and the other end is rotatably connected to the inner wall of the converter 30. The rotation axis of the adjusting rotating pipe 510 is parallel to the axis of the converter 30; the exhaust pipe adjusting rack 520 is fixed on the outer wall of the exhaust pipe 350 and extends along the axial direction of the exhaust pipe 350; the exhaust pipe gear 530 is fixed on the outer periphery of the adjusting rotating pipe 510 and meshes with the exhaust pipe 350 adjusting gear.

[0069] Referring to Figure 2 and Figure 3 , when it is necessary to sample the front-section urine, rotate the adjusting rotating pipe 510 to increase the length of the exhaust pipe 350 extending into the urine collection tube 20 by using the adjusting rotating pipe 510. When the urine liquid level in the urine collection tube 20 reaches the nozzle of the exhaust pipe 350, the gas in the urine collection tube 20 cannot be discharged, and the urine cannot continue to enter the urine collection tube 20, and the excess urine is discharged through the liquid discharge port 313; when it is necessary to sample the front-section urine and the middle-section urine, reduce the length of the exhaust pipe 350 extending into the urine collection tube 20, and use the urine collection tube 20 to collect the front-section urine + middle-section urine.

[0070] Referring to Figure 2 and Figure 4 , in order to separately sample and collect the middle-section urine, the exhaust pipe adjusting device 50 further includes a seal plug adjusting assembly 540 for adjusting the position of the front-section urine seal plug 410. The seal plug adjusting assembly 540 includes a seal plug adjusting rack 541, a seal plug adjusting gear 542, and a gear limiting member. The seal plug adjusting rack 541 is fixed on the outer periphery of the seal plug fixing rod 420 and extends along the axial direction of the seal plug fixing rod 420; the seal plug adjusting gear 542 is sleeved on the outer periphery of the adjusting rotating pipe 510 and meshes with the seal plug adjusting gear 542; the gear limiting member is arranged in the adjusting rotating pipe 510 so that when the adjusting rotating pipe 510 rotates, it can drive the seal plug adjusting gear 542 to rotate or not drive the seal plug adjusting gear 542 to rotate.

[0071] Referring to Figure 4 , the gear limiting member includes a gear limiting wedge 543, a push rod 544, a push rod limiting wedge 545, and a wedge reset member 546. The gear limiting wedge 543 is slidably connected to the side wall of the adjusting rotating pipe 510 along the radial direction of the adjusting rotating pipe 510. A plurality of gear limiting wedges 543 are arranged along the circumferential direction of the adjusting rotating pipe 510, and the outer walls of the plurality of gear limiting wedges 543 can frictionally abut against the outer wall of the seal plug adjusting gear 542;

[0072] The push rod 544 is slidably connected to the inside of the adjustment rotary tube 510 along the axial direction of the adjustment rotary tube 510, and one end of the push rod 544 extends out of the adjustment rotary tube 510; the push rod limit wedge 545 is fixed to the end of the push rod 544 located inside the adjustment rotary tube 510 and is slidably connected to the inner wall of the adjustment rotary tube 510, and the wedge-shaped surface of the push rod limit wedge 545 is slidably abutted against the wedge-shaped surface of the gear limit wedge 543. During specific operation, the push rod 544 is pushed into the adjustment rotary tube 510, and the push rod limit wedge 545 pushes the gear limit wedge 543 to move towards the outside of the adjustment rotary tube 510. The gear limit wedge 543 limits the sealing plug adjustment gear 542. At this time, when the adjustment rotary tube 510 is rotated again, the front-section urine sealing plug 410 can be opened by using the adjustment rotary tube 510, and the front-section urine can be temporarily stored in the front-section urine temporary storage cavity 330, so that the collecting urine tube 20 can effectively collect the middle-section urine.

[0073] Wherein, the wedge reset member 546 is arranged inside the adjustment rotary tube 510 to reset the gear limit wedge 543 into the adjustment rotary tube 510. A reset member fixing rod 547 is fixed inside the adjustment rotary tube 510. In this embodiment, the wedge reset member 546 is a compression spring. One end of the compression spring is connected to the reset member fixing rod 547, and the other end is connected to the gear limit wedge 543. When no force is applied to the push rod 544, under the action of the wedge reset member 546, the gear limit wedge 543 retracts into the adjustment rotary tube 510, and the gear limit wedge 543 does not limit the sealing plug adjustment gear 542; at this time, the adjustment rotary tube 510 can be rotated independently, and the length of the exhaust pipe 350 extending into the collecting urine tube 20 can be adjusted by using the adjustment rotary tube 510, so as to control the urine collection volume of the middle-section urine.

[0074] In addition, a scale mark is arranged on the end face of the converter 30 close to the end of the adjustment rotary tube 510, and the user can judge and adjust the urine volume that the collecting urine tube 20 can sample through the scale mark.

[0075] In addition, the urine funnel 10 can be set to a structure with one side higher and the other side lower, and the urine funnel 10 can rotate relative to the converter 30. When the female is the sampled person, the use state refers to Figure 2 When the male is the sampled person, the use state refers to Figure 5 . Through such a setting, the applicability of the urine collector can be further improved.

[0076] The implementation principle of a urine collector for sampling according to requirements in an embodiment of the present application is as follows: the original state of the urine collector is set to sample the front-section urine. Urine can enter the converter 30 through the urine funnel 10 and enter the collecting urine tube 20 through the liquid collecting port 312. When the urine in the collecting urine tube 20 reaches a certain amount, the urine blocks the nozzle of the exhaust pipe 350. At this time, the urine cannot continue to enter the collecting urine tube 20, and the urine is discharged through the liquid discharge port 313.

[0077] When it is necessary to change the sampling type, medical staff can pre-adjust the corresponding sampling type, and the person to be sampled can directly use this urine collector.

[0078] For example, when it is necessary to sample the initial urine and midstream urine, use the adjusting rotating tube 510 to adjust the length of the exhaust pipe 350 extending into the urine collecting tube 20 to shorten its length. At this time, the urine collecting tube 20 can collect more urine, and then collect the initial urine and midstream urine.

[0079] For example, when it is necessary to sample midstream urine, press the push rod 544 and rotate the adjusting rotating tube 510. Use the adjusting rotating tube 510 to move the initial urine sealing plug 410 away and open the initial urine inlet 331. At this time, the initial urine can enter the initial urine temporary storage cavity 330 through the initial urine inlet 331. After the initial urine temporary storage cavity 330 is full, the midstream urine continues to flow to the liquid collecting port 312 and enters the urine collecting tube 20. The urine collecting tube 20 collects the midstream urine, and when the urine collecting tube 20 is full, the urine continues to be discharged from the drain port 313 to achieve urine discharge.

[0080] The above is the selection and control of different sampled urine types. For different groups of people, this urine collector can also select samples according to specific situations.

[0081] For example, if the person to be sampled is a child and the child's urine is less, the urine volume of the initial urine and midstream urine is less. At this time, the adjusting rotating tube 510 can be rotated to make the length of the exhaust pipe 350 extending into the urine collecting tube 20 longer, so that the urine collecting tube 20 can accurately collect the initial urine or the initial urine + midstream urine. For example, if the person to be sampled is an adult and the adult's urine is more, the urine volume of the initial urine and midstream urine is more. At this time, the adjusting rotating tube 510 can be rotated to make the length of the exhaust pipe 350 extending into the urine collecting tube 20 shorter, so that the urine collecting tube 20 can accurately collect the initial urine or the initial urine + midstream urine.

[0082] For midstream urine, the child sampling population can, with the help of an assistant, control the urine volume discharged into the initial urine temporary storage cavity 330 to accurately obtain midstream urine; for adults, after the urine collector is adjusted to the corresponding sampling type, the midstream urine can be directly obtained by using the urine collector.

[0083] In summary, on the one hand, the solution of this application can sample according to the required urine type, and on the other hand, it can also select the appropriate sampling volume according to different groups of people, maximizing the accuracy of sampling.

[0084] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
