Description

Technical Field

[0001] The present invention relates to the technical field of urine detection, and more specifically, to a urine sampling device and a sampling method thereof. Background Art

[0002] Urine testing is a commonly used testing method in medicine, mainly used to evaluate physical health, diagnose diseases, and monitor the effectiveness of disease treatment. In medicine, urine can be tested for a number of things as needed, such as color and transparency, pH, protein, glucose, urine sediment examination, white blood cell count, crystals and precipitates, urine culture, and drug sensitivity testing. Since urine samples are easy to obtain and can be tested in a variety of ways, urine testing is widely used in clinical diagnosis, health examinations, and disease monitoring and management. It is a very useful and convenient testing method.

[0003] In the existing urine testing sampling method, in order to make sampling more convenient, simple disposable urine test cup self-service sampling is often used, that is, the patient holds a plastic urine test cup and uses it to collect urine when urinating. However, this method can easily cause urine to splash on the hands, and the urine test cup needs to be removed after it is full. The removal process can easily cause urine to spill, thereby causing sampling failure.

[0004] In the prior art, in order to make urine sampling more hygienic and clean, a larger container is designed to receive the urine first, and then a diversion device is used to transport it to the sampling tube. When using this type of device, the patient can continue to urinate, and the equipment will automatically receive the urine to be sampled. There is no need to hold the urine, and there is no need to hold the urine during urination, which is cleaner.

[0005] For urine testing of some patients, it is necessary to maintain a more accurate sampling effect to avoid the influence of other factors on urine testing. For example, in some urine tests, patients are required to select urine after the first urination in the morning as a sample. Moreover, during the urination process, the front urine may contain higher concentrations of bacteria, residual substances and other components that may interfere with the test. Therefore, in order to ensure the accuracy and reliability of urine testing, it is generally recommended that the urine sample collected should be mid-urine, that is, the middle part of the urination process. In this way, the interference factors that may be caused by the front urine can be avoided as much as possible, and the scientificity and reliability of the test results can be ensured.

[0006] Although the sampling device can actively collect mid-end urine after a period of urination according to the urination time, since the first urine in the morning is selected, most people are in a "urine holding" state, that is, the amount of urine is large. When urinating, the urine flows with great force. When the urine hits the device, due to the strong fluidity of urine, a large number of small area splashes are easily generated, causing a large amount of front urine to be scattered on the sampling device and mixed with the subsequent mid-end urine. As a result, when the device drives the sampling tube to start collecting, the collected mid-end urine will also contain some front-end urine, which will cause certain contamination to the urine sample and affect the high-precision detection of urine. Summary of the invention

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Refer to the instruction manual Figures 1 to 13A urine sampling device comprises a receiving bucket 1, a covering film 2 and a sample storage device 3. An end plate 11 is arranged on the top of the receiving bucket 1, a boss 12 is arranged inside the receiving bucket 1, a slot 13 is arranged in the boss 12, the covering film 2 is a funnel-shaped deformable structure, such as a plastic film, a cling film, etc., and has a certain elasticity. A perforation 21 is arranged at the center of the covering film 2, a film edge 22 is arranged on the top of the covering film 2, and the film edge 22 is used to fit with the end plate 11. A film edge fixing structure 111 for fixing the film edge 22 is arranged on the end plate 11. The sample storage device 3 comprises a sampling tube 31, and the sampling tube 31 is arranged corresponding to the perforation 21 and the boss 12. A damping sleeve 6 cooperating with the sampling tube 31 is arranged in the slot 13, and there is friction resistance between the damping sleeve 6 and the sampling tube 31, wherein the damping sleeve 6 is preferably a rubber sleeve structure and has a certain elasticity.

[0036] During assembly, the film 2 is placed in the receiving bucket 1, and the film edge 22 is fitted against the end plate 11 (water is sprinkled on the end plate 11 in advance to help the film edge 22 to be adsorbed and fixed), and the film edge fixing structure 111 fixes the film edge 22, and the perforation 21 is aligned with the slot 13, and the bottom of the film 2 is fitted against the top of the boss 12. Finally, the sampling tube 31 is inserted along the slot 13, so that the flange portion 311 squeezes the material of the film 2 near the perforation 21 and fixes it on the boss 12. The boss 12 is a protruding structure, so the film 2 is formed with a concave structure around the boss 12. After the sampling tube 31 is inserted into the slot 13, the damping sleeve 6 contacts the slot 13 and provides friction resistance, so that the center of the film 2 can be firmly fixed on the slot 13.

[0037] A plurality of partition convex plates 14 are fixedly connected to the inner wall of the receiving bucket 1, and the bottom ends of the partition convex plates 14 extend to the top of the boss 12 and are higher than the top of the boss 12. After the film 2 is placed in the receiving bucket 1, the area in contact with the partition convex plates 14 is lifted up by the partition convex plates 14, so that a plurality of concave spaces are formed on the inner side of the film 2, and a plurality of buffer convex plates 15 are also arranged in the inner wall of the receiving bucket 1. The buffer convex plates 15 are used to form a gap between the film 2 and the inner wall of the receiving bucket 1, so that most of the film 2 is in an unsupported suspended state.

[0038] A lifting mechanism 4 is also provided at the bottom of the receiving bucket 1. The lifting mechanism 4 is used to drive the sampling tube 31 to rise in the slot 13, so that it is convenient to take it out after the sampling is completed.

[0039] During actual sampling, the patient urinates toward the side wall of the receiving bucket 1. During urination, the urine directly impacts the membrane 2. Since the membrane 2 is suspended under the support of the buffer convex plate 15, and the membrane 2 itself is relatively soft and has a certain elasticity, it can effectively buffer the impacting fluid, thereby preventing urine from splashing, and further preventing the front urine from mixing with the middle urine. After the urine impacts the membrane 2, it will flow down along the membrane 2. Since the convex platform 12 props up the middle part of the membrane 2, the urine will flow into the concave structure of the membrane 2. Since the partition convex plate 14 separates the membrane 2 into a plurality of concave spaces, the discharge can be adjusted during actual use. The actual direction of urine and the receiving bucket 1 is changed by changing the concave space corresponding to urination, so that urine at different stages can be stored. For example, at the beginning, the patient urinates toward the first concave space, and the front urine discharged is stored in the first concave space, and then the patient adjusts the urination direction to align with the subsequent other concave spaces (the patient can also remain motionless, and use an automated control device to control the rotation of the receiving bucket 1 to adjust the other concave spaces to align with the patient), so that the front urine and the middle urine can be distinguished. It should be noted that the first concave space should be replaced before it is full of urine, and during subsequent urination, it is necessary to wait for the middle urine to fill the concave space in this area. Please refer to the attached manual for details. Figure 5 , until the urine in the concave space overflows the top of the sampling tube 31, overflows into the sampling tube 31, and until the sampling tube 31 is full. After it is full, you can continue to urinate into other concave spaces, or you can urinate outside the receiving bucket 1. Since the receiving bucket 1 is covered and blocked by the film 2 as a whole, even if you urinate outside later, when the urine spills on other parts of the receiving bucket 1, it will be blocked by the film 2 and will not pollute the receiving bucket 1. After the sampling is completed, the sampling tube 31 is pushed out of the receiving bucket 1 by the lifting mechanism 4 to complete the sampling. During the process, the film 2 buffers the urine and can avoid urine splashing. While ensuring that the front urine and the middle urine will not mix, it will not cause urine to splash onto the patient or other places, making urine sampling cleaner and more convenient, and ensuring the accuracy of urine sampling.

[0040] In the above embodiment, the device can be designed as a sampling device for sampling, or it can be used in combination with a toilet. For example, refer to the attached manual. Figure 1 and Figure 3 A fixing frame 5 is provided on the receiving bucket 1, and a snap-fitting structure for snapping and fixing with the toilet is provided on the fixing frame 5, so that the receiving bucket 1 can be hung in a designated area when not in use, and the fixing frame 5 is placed on the toilet to place the receiving bucket 1 in the toilet when it is needed, and the coating 2 can be designed as a disposable product, so that the receiving bucket 1 can be reused, and the sampling tube 31 can be directly used as a test tube structure, which can be distributed by the hospital or obtained by oneself when needed, and then installed on the receiving bucket 1 with the coating 2 for sampling.

[0041] For further information, please refer to the attached manual. Figure 5 , the present embodiment also provides a solution for automatically discharging urine in and out of the coating 2. Specifically, a discharge hole 16 is provided at the position of each concave space in the area between the receiving bucket 1 and the boss 12. A puncture structure 161 is provided in the discharge hole 16. When the amount of urine in the concave space corresponding to the coating 2 increases and causes it to deform downward and contact the puncture structure 161, the puncture structure 161 punctures the coating 2 at that position, so that the urine in the concave space can be discharged downward from the discharge hole 16 into the toilet. In order to prevent the front end urine from overflowing into the sampling tube 31, the top of the puncture structure 161 corresponding to the first concave space is higher than the top of the puncture structure 161 at other positions. Among them, the area of ​​the first concave space needs to be marked accordingly to ensure that the concave space corresponding to the position is reached when urination begins. Due to the puncture structure in this area 161 is higher, therefore, less urine is collected in the concave space, and the film 2 at this position can be punctured by the puncture structure 161 after gravity is applied to the film 2 at this position, and the urine is discharged, and then the concave space corresponding to the patient's urination can be adjusted to provide the patient with adjustment reaction time. The remaining positions can store more urine because the puncture structure 161 is lower until it overflows into the sampling tube 31. Even if the film 2 at this position has been punctured by the puncture structure 161 before the urine in the concave space in other areas overflows into the sampling tube 31, the urine discharge speed of the punctured film edge 22 is slower, while the patient urinates faster, so it is still possible to ensure that the urine in the middle end can overflow into the sampling tube 31. After the sampling tube 31 is full and the patient finishes urinating, it is possible to wait until all the urine in the film 2 is discharged, and then push the sampling tube 31 out, refer to the attached manual. Figure 6 , thereby preventing the side wall of the ejected sampling tube 31 from contacting urine, thereby making it convenient for the patient to completely remove the sampling tube 31 by holding the side wall of the sampling tube 31 .

[0042] It should be noted that the puncturing structure 161 can be a needle structure or a blade structure. In order to improve the accuracy of the device, a cylinder or other structure can be provided to automatically control the movement of the puncturing structure 161 to puncture the coating 2 at the corresponding position when necessary.

[0043] Further, in order to ensure that the urine in the sampling tube 31 will not leak after being taken out, refer to the attached manual. Figure 6 The sample storage 3 also includes a sealing cover 32, on which a sealing plug-in structure for inserting into the sampling tube 31 and sealingly engaging with the sampling tube 31 is provided. A shielding sleeve 321 is provided on the outside of the sealing cover 32. When the sealing cover 32 and the sampling tube 31 are inserted, the shielding sleeve 321 covers the outside of the flange portion 311.

[0044] It should be noted that, although the outer wall of the sampling tube 31 does not contact urine during sampling, when urine overflows from the top of the sampling tube 31 into the sampling tube 31, the urine will contact the flange 311 and its top. Therefore, after sampling is completed, the sampling tube 31 can be manually sealed using the sealing cover 32, and the top area of ​​the sampling tube 31 can be covered, thereby preventing the patient from touching this position and being contaminated by urine, making the sampling process cleaner.

[0045] In the above embodiment, in order to make the device more convenient to use, the patient does not need to adjust the urination direction by himself. Figure 7 and Figure 8 A bracket 51 is fixedly connected to the fixed frame 5, the receiving bucket 1 is rotatably installed in the bracket 51, and the end plate 11 is rotatably set on the top of the bracket 51 without affecting the installation of the coating 2. A rotation driver 52 is installed in the bracket 51, and the rotation driver 52 is used to drive the receiving bucket 1 to rotate, wherein the rotation driver 52 can select a motor structure, and a gear is installed on the output shaft of the motor, and then a corresponding gear ring structure is set at the bottom of the end plate 11, and the rotation drive of the receiving bucket 1 is realized by means of the cooperation of the gear and the gear ring, and then in actual use, the rotation of the receiving bucket 1 can be automatically controlled to adjust the area corresponding to the patient's urination, without the patient adjusting the urination direction.

[0046] It should be noted that the above-mentioned scheme of controlling the rotation of the receiving bucket 1 can not only adjust the concave space of the coating 2, but also control the receiving bucket 1 to rotate back and forth quickly after the sampling tube 31 is full of urine, so that the urine at the top of the sampling tube 31 is thrown out by centrifugal force, as shown in the attached manual. Fig. 9 , and then let it stand and wait for the urine in the sampling tube 31 to stabilize, so that when the sampling tube 31 is pushed out later, due to the reduction of urine in the sampling tube 31, the liquid level is lower than the top of the sampling tube 31. In this process, urine will not spill out and contaminate the side wall of the sampling tube 31, ensuring the cleanliness of the side wall of the sampling tube 31.

[0047] In this embodiment, the membrane edge fixing structure 111 can adopt a simple convex nail structure, and a corresponding positioning hole is set on the membrane edge 22, and the membrane edge 22 is fixed by means of the cooperation of the two. However, the convex nail structure protrudes from the membrane edge 22 and is easily stained with urine. Therefore, a vacuum adsorption hole can also be set on the end plate 11 to adsorb and fix the membrane edge 22. For example, in the scheme of adopting the above-mentioned rotatable receiving bucket 1, a negative pressure chamber can be set at the position of the bracket 51 corresponding to the end plate 11, and the negative pressure chamber is connected to the vacuum pump through a pipeline, and a negative pressure hole is set at the position corresponding to the negative pressure chamber on the end plate 11, and multiple groups of negative pressure holes are set along the circumferential direction. Therefore, on the basis of ensuring that the receiving bucket 1 can rotate, the scheme of negative pressure adsorption of the membrane edge 22 can also be realized.

[0048] In the above embodiment, when sampling is completed, the sealing cover 32 is covered with the perforation 21, and then the sampling tube 31 is pushed out. After removing the sampling tube 31, the entire film 2 can be taken out and discarded using a clamp lamp device, and then the receiving bucket 1 is cleaned as a whole and placed in other locations for subsequent use.

[0049] Among them, refer to the instructions attached Figure 5 and Figure 6 The lifting mechanism 4 used in this embodiment can adopt a simple lifting structure. For example, the lifting mechanism 4 includes a lifting rod 41 and a linear driver 42. The lifting rod 41 is slidably installed in the slot 13, and the linear driver 42 is fixedly installed at the bottom of the receiving bucket 1. The lifting rod 41 is fixedly installed on the output end of the linear driver 42. The linear driver 42 can adopt a cylinder or hydraulic cylinder structure, thereby being able to achieve effective lifting of the sampling tube 31.

[0050] Furthermore, this embodiment also provides another lifting method. For details, refer to the attached manual. Figures 10 to 12 A lifting sleeve 17 is slidably installed in the boss 12, the slot 13 is formed inside the lifting sleeve 17, and the damping sleeve 6 is installed in the lifting sleeve 17, the top end surface of the lifting sleeve 17 cooperates with the flange portion 311, and a limiting structure for limiting the lifting sleeve 17 is provided at the top of the inner cavity of the boss 12. The limiting structure is used to limit the lifting sleeve 17 from moving out of the boss 12, and a sealing structure is provided between the lifting sleeve 17 and the boss 12, and a liquid delivery pipe 43 is provided at the bottom of the lifting sleeve 17, the liquid delivery pipe 43 is connected to the inner cavity of the lifting sleeve 17, the liquid delivery pipe 43 is fixedly installed on the receiving bucket 1, and the liquid delivery pipe 43 is connected to a water pump through a pipeline.

[0051] In actual use, the flange 311 and the end of the lifting sleeve 17 are fixed to the center of the coating 2. When the sampling is completed, the water pump is controlled to inject water into the inner cavity of the lifting sleeve 17. Since the damping sleeve 6 is in close contact with the sampling tube 31 and has a certain sealing performance, the water pressure in the lifting sleeve 17 gradually increases, and the lifting sleeve 17 can be lifted up together with the sampling tube 31. Fig.11 At this time, the residual urine in the film 2 can be concentrated and flow downward from the hole punctured by the puncture structure 161 previously. The water pressure can be increased afterwards. After the lifting sleeve 17 is restricted by the limiting structure, the continuous increase in water pressure can lift the sampling tube 31 upward in the lifting sleeve 17, and then the sampling tube 31 can be taken away. This method can increase the rising height of the sampling tube 31 and reduce the contact probability between the patient and the film 2. At the same time, the height of the middle area of ​​the film 2 can also be increased after use, which makes it convenient to operate the film 2 when taking it out, and the residual urine in the film 2 will not enter the slot 13 from the perforation 21.

[0052] It should be noted that the two lifting mechanisms 4 provided in this embodiment can be used separately or together. When used together, attention should be paid to the setting positions of the liquid delivery pipe 43 and the linear drive 42 to avoid interference.

[0053] For further information, please refer to the attached manual. Fig.10 and Fig.11 The bottom of the sampling tube 31 is fixedly connected with an elastic membrane 312. During the sampling process, when the liquid delivery tube 43 is not filled with water, that is, when there is no water pressure at the bottom of the elastic membrane 312, the elastic membrane 312 bulges downward. When the sampling is completed and the liquid delivery tube 43 begins to be filled with water, the elastic membrane 312 can be bulged upward under the action of the water pressure, thereby squeezing out a part of the urine in the sampling tube 31. When the sampling tube 31 is pushed out, water begins to be released through the liquid delivery tube 43, the water pressure at the bottom of the elastic membrane 312 disappears, and the elastic membrane 312 is concave again, thereby lowering the liquid level of the urine in the sampling tube 31, thereby preventing excessive urine from overflowing when the sealing cover 32 is installed.

[0054] Based on the above solution, this embodiment also provides a solution for flushing the coating 2. For details, refer to the attached manual. Fig.11 and Fig.13 A gap is provided between the lifting sleeve 17 and the sampling tube 31, a liquid outlet gap 61 is provided at the position of the damping sleeve 6 corresponding to the sampling tube 31, a liquid outlet hole 314 is provided in the flange portion 311 which passes through the flange portion 311 from top to bottom, the liquid outlet hole 314 is provided corresponding to the liquid outlet gap 61, an elastic shielding sheet 313 is fixedly installed on the top of the flange portion 311, the elastic shielding sheet 313 is elastic, and the elastic shielding sheet 313 covers the outside of the liquid outlet hole 314.

[0055] It should be noted that the elastic shielding sheet 313 can be made of a plastic sheet or a rubber sheet. During the sampling process, the elastic shielding sheet 313 blocks the liquid outlet 314 due to its elasticity, so urine will not enter the liquid outlet 314. When the sampling is completed and the liquid delivery pipe 43 injects water into the lifting sleeve 17, the water flows upward through the liquid outlet slit 61 and flows out through the liquid outlet 314, pushing the elastic shielding sheet 313 open, thereby forming a water flow that sprays outward along the circumferential direction of the sampling tube 31 to rinse the film 2. At the same time, since the water flow out of the liquid outlet 314 is limited and the flow is blocked, the water pressure in the lifting sleeve 17 can still lift the sampling tube 31 without affecting the sampling. The tube 31 is lifted, and water flows through the outer wall of the sampling tube 31, which can effectively clean the outer wall of the sampling tube 31, further ensuring the cleanliness of the outer wall of the sampling tube 31, and when the sealing cover 32 is covered, the elastic shielding sheet 313 can also be used as a seal between the sampling tube 31 and the sealing cover 32 to save costs. At the same time, since the film 2 can be cleaned, when the film 2 is taken out, the film 2 is also neater and will not be affected by touching the patient. After the sampling tube 31 and the film 2 are taken away, water can be supplied to the lifting sleeve 17 again, so that the water flows into the receiving bucket 1 and then flows out through the discharge hole 16, thereby completing the automatic cleaning of the receiving bucket 1 without the need for manual cleaning by the patient.

[0056] The urine sampling device provided by the present invention is easy to use, the receiving bucket 1 can be reused, the coating 2 can use low-cost materials as a disposable product, and the sample storage 3 can be directly used as a test tube. Therefore, the overall cost is relatively low, and the device can be placed in a toilet for use with the toilet. Therefore, it can be used by all types of patients, including men, women, the elderly and children. It is highly practical, the sampling process can be kept clean, and the patient can continue to urinate during sampling without interruption, which provides a good experience.

[0057] Refer to the instruction manual Fig.14 The present invention also provides a urine sampling method, comprising the following steps: Step 1: Place the receiving bucket 1 in the toilet, then spread the film 2 in the receiving bucket 1, and align the sampling tube 31 with the through hole 21 and insert it into the slot 13; Step 2: The patient starts to urinate, releasing the front urine of the morning urine; Step 3: Adjust the corresponding positions of the urination and receiving buckets 1 so that the urine is away from the concave space of the first docking film 2; Step 4: Continue urinating until urine overflows from the top of the sampling tube 31 into the sampling tube 31; Step 5: After the patient has finished urinating, wait for the remaining urine in the film 2 to be discharged, and then cover the sealing cover 32 on the sampling tube 31; Step 6: Push the sampling tube 31 upwards through the lifting mechanism 4 to expose the outer wall of the sampling tube 31; Step 7: Hold the outer wall of the sampling tube 31 and take away the sampling tube 31 to complete the sampling; Step eight, take out the film 2, discard it in a trash can, flush the receiving bucket 1, and then take the receiving bucket 1 out of the toilet and place it in a designated location.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
