Abstract
Description
Technical Field
[0001] The utility model relates to the field of urine cups, in particular to a urine cup. Background Art
[0002] According to the Health Industry Standard of the People's Republic of China - Guidelines for Clinical Microbiology Laboratory Examination of Urine Specimens (WS / T489-2024): Urine laboratory examinations are the primary method for diagnosing, assisting in diagnosis, observing therapeutic effects, and assessing prognosis of urinary tract infections. Urine sediment Gram stain and acid-fast stain microscopy are rapid and convenient screening methods. Urine culture is an important method for diagnosing urinary tract infections, providing pathogen counts and identification results, and enabling further antibiotic susceptibility testing.
[0003] Minimizing sample contamination is key to ensuring urine quality. Therefore, before collecting midstream urine, the area around the urethral opening should be cleaned. Women should separate the labia majora, and men should retract the foreskin for cleaning. Currently, when outpatients collect their own midstream urine, they often fail to properly clean the area around the urethral opening, leading to contamination of the urine with skin-colonized bacteria and affecting urine culture results.
[0004] A urine cup is a container used to transport urine specimens. Currently, most laboratories use wide-mouth, flat-bottomed urine cups. However, existing cups are not compatible with common laboratory centrifuges and have flat bottoms. According to the aforementioned national standard (WS / T489-2024), to improve the isolation rate of fungi and mycobacteria, it is recommended that urine specimens be centrifuged before fungal and mycobacterial culture. Furthermore, urine specimens requiring Gram stain and / or acid-fast staining for microscopic examination must also be centrifuged and the urine sediment collected for slide preparation. Urine specimens transported using existing urine cups must be transferred to a centrifuge tube and then centrifuged in a centrifuge for isolation, culture, or slide preparation. This process is highly susceptible to specimen contamination due to human error, affecting the final test results. Utility Model Content
[0005] The purpose of the utility model is to address the deficiencies in the existing technology and provide an integrated urine cup for midstream urine collection, transportation, inoculation and preparation, thereby avoiding urine contamination and ensuring the reliability of test results.
[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:
[0007] A urine cup, comprising:
[0008] The cup body comprises a tube body and a conical plate, wherein the conical plate is arranged inside the tube body, the centrifugal chamber is formed between the conical plate and the upper end of the tube body, and the storage chamber is formed between the conical plate and the lower end of the tube body;
[0009] A cup cover, comprising a cover body and an inoculating loop, wherein the cover body is threadedly connected to the upper port, and the inoculating loop is connected to the cover body and is located in the centrifugal chamber;

[0011] As a preferred embodiment, the cup cover includes:
[0012] A telescopic body is connected between the cover body and the inoculation ring.
[0013] As a preferred embodiment, the upper port is provided with a slot, the width of the slot is smaller than the diameter of the inoculation ring, and the width of the slot is larger than the diameter of the telescopic body, so that the telescopic body is located in the slot 1, and when the inoculation ring abuts against the inner wall of the upper port, the cover body is dragged to stretch the telescopic body.
[0014] As a preferred embodiment, the outer wall of the upper port is provided with an external thread, and the depth of the groove is not greater than the thread length of the external thread.
[0015] As a preferred embodiment, the cover body includes a cover plate and a side plate, the edge of the cover plate extends downward to form the side plate, the inner wall of the side plate is provided with an internal thread, the center of the cover plate is connected to the telescopic body, and the telescopic body is located below the cover plate.
[0016] As a preferred embodiment, the diameter of the conical plate gradually decreases from top to bottom.
[0017] As a preferred embodiment, the volume of the centrifugal chamber is larger than the volume of the storage chamber.
[0018] As a preferred embodiment, the lower port of the tube body is adapted to be installed on a centrifuge.
[0019] As a preferred embodiment, the sterile cotton ball is soaked in iodine solution.
[0020] As a preferred embodiment, the closing body is a tearable film.
[0021] Compared with the existing technology, this technical solution has the following advantages:
[0022] Sterilized cotton balls are placed in the storage cavity of the cup body. The patient can open and remove the closing body of the lower port and directly take the sterilized cotton balls to clean the area around the urethral opening, reduce sampling contamination, and ensure urine quality.
[0023] The retractable inoculating loop fixed inside the cover can be used immediately after opening the cover, thus avoiding deformation and contamination of non-disposable inoculating loops during use and ensuring the reliability of the test results.
[0024] The retractable inoculation loop is designed to be used as soon as the lid is opened, which greatly reduces the time from opening the lid to inoculation, avoids the contamination of urine specimens by unclean air after opening the lid, and ensures the reliability of the test results.
[0025] The integrated urine cup is designed to the diameter of a commonly used laboratory centrifuge and has a conical pointed bottom that decreases from large to small from top to bottom. This can more effectively accumulate urine sediment after centrifugation, eliminating the step of changing specimen containers during the process, reducing the risk of specimen contamination due to human error, and ensuring the reliability of test results.

DETAILED DESCRIPTION
[0034] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0035] like Figure 1As shown, the urine cup comprises:
[0036] The cup body 100 includes a tube body 110 and a conical plate 120. The conical plate 120 is disposed inside the tube body 110. The centrifugal chamber 100a is formed between the conical plate 120 and the upper end 111 of the tube body 110, and the storage chamber 100b is formed between the conical plate 120 and the lower end 112 of the tube body 110.
[0037] The cup cover 200 includes a cover body 210 and an inoculating loop 220. The cover body 210 is threadedly connected to the upper port 111. The inoculating loop 220 is connected to the cover body 210 and is located in the centrifugal chamber 100a.
[0038] The sterile cotton ball 300 is located in the storage cavity 100 b , and a detachable closure body is provided on the lower port 112 .
[0039] The interior of the tube body 110 is divided into a centrifugal chamber 100a and a storage chamber 100b by the conical plate 120. The centrifugal chamber 100a is used to store midstream urine, and the storage chamber 100b is used to place the sterile cotton balls 300. The sterile cotton balls 300 can be used to clean the area around the patient's urethra before collecting midstream urine, reducing sampling contamination and ensuring urine quality. The cup cover 200 not only opens and closes the upper port 111, but also uses the inoculation loop 220 connected to the cup cover 200 to quickly dip the urine specimen and perform microbial culture inoculation on the culture medium plate, reducing the time the urine specimen is exposed to air after opening the cover.
[0040] The cup body 100 and the cup cover 200 can be sterilized by soaking in disinfectant, irradiating with ultraviolet light, etc., that is, the cup body 100 and the cup cover 200 are sterile products.
[0041] like Figure 1 As shown, the tube body 110 is a tubular structure, and the diameter of the conical plate 120 gradually decreases from top to bottom. The upper end of the conical plate 120 with a larger diameter is connected to the inner wall of the tube body 110 to separate the interior of the tube body 110 into a centrifugal chamber 100a and a storage chamber 100b, that is, the bottom of the centrifugal chamber 100a is a pointed test tube style.
[0042] The centrifugal chamber 100a and the storage chamber 100b are arranged from top to bottom, and the centrifugal chamber 100a and the storage chamber 100b are not connected. The tube body 110 and the conical plate 120 can be integrally connected and integrally injection molded.
[0043] refer to Figure 1The length of the centrifugal chamber 100a is longer than the length of the storage chamber 100b, that is, the volume of the centrifugal chamber 100a is larger than the volume of the storage chamber 100b. The storage chamber 100b only stores the sterile cotton balls 300, so the larger volume of the centrifugal chamber 100a can store a larger amount of urine.
[0044] like Figures 1 to 3 As shown, the cover 210 includes a cover plate 211 and a side plate 212. The edge of the cover plate 211 extends downward to form the side plate 212. The inner wall of the side plate 212 is provided with an internal thread 212a. The outer wall of the upper port 111 is provided with an external thread 111b adapted to the internal thread 212a to achieve a threaded connection between the cover 210 and the upper port 111.
[0045] refer to Figure 3 , the cup cover 200 includes:
[0046] The telescopic body 230 is connected between the cover plate 211 of the cover body 210 and the inoculation ring 220 .
[0047] The telescopic body 230 is a telescopic result, so the distance between the inoculating ring 220 and the cover body 210 can be adjusted, thereby adjusting the depth of the inoculating ring 220 inserted into the centrifugal chamber 100a.
[0048] refer to Figure 4 The telescopic body 230 includes at least two rods 231, and the two adjacent rods 231 are socketed, that is, the rod 231 located inside can be telescoped to the inside of the rod 231 located outside. Its specific structure can refer to patents CN108757669A, CN117212309A, etc.
[0049] Specifically, the telescopic body 230 is connected to the center of the cover plate 211 and is located below the cover plate 211 like the side plate 212 .
[0050] The inoculation loop 220 may be an inoculation loop for 1 μL quantification.
[0051] like Figure 2 As shown, the upper port 111 is provided with a slot 111a, the width of the slot 111a is smaller than the diameter of the inoculation ring 220, and the width of the slot 111a is larger than the diameter of the telescopic body 230, so that the telescopic body 230 is located in the slot 111a, and when the inoculation ring 220 abuts against the inner wall of the upper port 111, the cover 210 is dragged to stretch the telescopic body 230, with reference to Figure 5 and Figure 6 Similarly, the cover 210 is pressed to shorten the length of the telescopic body 230 .
[0052] In this way, during the process of extending and shortening the telescopic body 230, there is no need to contact the telescopic body 230 and the seed ring 220 containing urine to stretch or retract the telescopic body 230, thereby further avoiding urine contamination and avoiding contamination of the inoculation ring 220 during use.
[0053] like Figure 2 As shown, the outer wall of the upper port 111 is provided with an external thread 111b, and the threads from the first circle to the last circle of the external thread 111b are arranged from bottom to top, wherein the lowest position of the depth of the groove 111a is slightly higher than the first circle of the thread, that is, the depth of the groove 111a is not greater than the thread length of the external thread 111b, and while the groove 111a can accommodate the telescopic body 230, the threaded connection ability of the external thread 111b and the internal thread 212a of the cover body 210 is guaranteed, thereby preventing urine leakage due to the excessive depth of the groove 111a when the cover body 210 is threadedly connected to the upper port 111 of the tube body 110.
[0054] like Figure 1 As shown, the storage cavity 100b is used to place the sterile cotton ball 300, which is used to clean the area around the urethra before the patient collects midstream urine, reduce sampling contamination, ensure urine quality, and solve the problem of reducing midstream urine collection contamination.
[0055] The sterile cotton ball 300 is soaked in 1% iodine tincture solution.
[0056] The lower port 112 is provided with a detachable closing body, and after removing the closing body, the sterilizing cotton ball 300 can be taken out. Preferably, the closing body is a tearable film.
[0057] The diameter of the tube body 110 is the same as that of a common centrifuge tube in a laboratory, that is, the tube body 110 can be directly placed on a centrifuge for centrifugation, and then the urine sediment is taken for preparation and inoculation. Figure 1 After removing the sealing member and the sterile cotton ball 300, the lower end of the tube 110 is adapted to be mounted on the centrifuge, eliminating the need to switch specimen containers during the process. This reduces the risk of specimen contamination due to human error and reduces the risk of specimen contamination caused by container switching during urine specimen centrifugation, thereby ensuring the reliability of the test results.
[0058] At present, the use of a 1μL quantitative inoculation loop to inoculate urine is the main inoculation method for urine culture colony counts in clinical microbiology laboratories. When inoculating urine specimens in clinical microbiology laboratories, after opening the lid of the urine cup, the standard quantitative inoculation loop is vertically immersed in the urine specimen, the specimen is sucked into the loop, and then inoculated on the culture medium plate. Most clinical laboratories use non-disposable metal quantitative inoculation loops for inoculation. However, the repeated high-temperature sterilization and cooling process can easily cause the metal inoculation loop to deform, thereby affecting the colony count results. In addition, the non-disposable metal quantitative inoculation loop after high-temperature sterilization is generally placed in a biosafety cabinet to wait for inoculation after cooling. The space inside the biosafety cabinet is not sterile, and placing it for too long can easily cause contamination of the urine sample and the quantitative inoculation loop. The retractable inoculation loop 220 fixed to the inside of the cover 210 of this embodiment can be used as soon as the lid is opened, avoiding deformation and contamination of the non-disposable inoculation loop during use and ensuring the reliability of the test results.
[0059] Before collecting midstream urine, the patient can use the sterilized cotton ball attached to the bottom of the cup body 100 to clean the area around the urethral opening, then introduce the urine into the centrifugal chamber 100a, and close the upper port 111 with the cup cover 200. After that, the experimenter removes the cup cover 200 and clamps the telescopic body 230 into the clamping groove 111a of the upper port 111 to stretch the length of the telescopic body 230. Then, the inoculation loop 220 connected to the telescopic body 230 is inserted into the interior of the centrifugal chamber 100a, and the urine specimen is dipped and inoculated on the culture medium plate for microbial culture. When the urine specimen is stained for microscopic examination and / or fungal or mycobacterial culture, the inoculation loop 220 can be retracted and the cup body 100 can be directly placed in a centrifuge for centrifugation. After that, the urine sediment is taken for preparation and inoculation. Therefore, the urine cup of this embodiment integrates transportation, collection, inoculation and preparation.
[0060] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
