[0002] The laboratory is an important department in hospitals and medical institutions, mainly responsible for testing and analyzing various biological samples of patients. These samples can include blood, urine, tissue specimens, etc. Through testing and analysis, they provide objective basis for the diagnosis, treatment, prevention and prognosis of clinical diseases, helping doctors to diagnose diseases, evaluate conditions and monitor treatment effects. When testing biological samples, the laboratory usually needs to use an auxiliary sampler to collect samples, and then test the samples in the sampler.

[0003] In the prior art, during the urine sampling process, a urine cup is usually used to obtain a urine sample, and then the urine sample in the urine cup is poured into an open sampling tube, and finally the open sampling tube is inserted into the placement hole of the placement rack. When there are a certain number of sampling tubes on the placement rack, the sampling tube is sent to the inspection room for urine testing.

[0017] Compared with the prior art, the invention has the following beneficial effects.

[0018] 1. When the present invention is used, the sampling tube is rotated so that the fixing rod is snapped into the buckle at the corresponding position, and the sampling tube is connected to the urine collecting cup. When the sampling tube rotates, the second urination plate is driven to rotate together, and the rubber block leaves the urination hole. At this time, the urine collecting cup, the urination tube, the first urination plate, the sealing tube and the sampling tube are in a connected state. The urine collecting cup and the sampling tube are spliced ​​into an integrated type, which is more convenient for sampling. There is no need to pour the urine sample in the urine collecting cup into the sampling tube separately, which avoids urine accidentally spilling on the hands or dripping on the ground, causing hygiene problems. After a proper amount of urine sample is collected in the sampling tube, the sampling tube is rotated in the opposite direction to pull the fixing rod out of the buckle, and the second urination plate is driven to rotate in the opposite direction so that the rubber block covers the urination hole again, thereby sealing the second urination plate. The sampling tube is then moved downward to separate it from the urine collecting cup. At this time, the urine sample in the sampling tube is in a sealed state. When the sampling tube is inserted into the placement rack, the urine sample inside will not directly contact the air, avoiding dust pollution and volatilization of urine components, which is conducive to improving the accuracy of the test results.

[0019] 2. When using the present invention, tear off the sterile patch, then hold the sampling tube in your hand, and press the pressing button plate to make the piston move in the piston tube, the pressure inside the disinfection bottle increases, and the disinfectant enters the pipette, the telescopic tube and the connecting tube, pushing the movable ball to move upward, and then enters the nozzle, and the pressing button plate is pressed again. The airflow enters the nozzle and the connecting tube respectively. The disinfectant is affected by the impact of the airflow, pushing the movable ball to move downward, closing the outlet, and the disinfectant in the nozzle is blown by the nozzle and sprayed outward. By repeatedly pressing the pressing button plate, the disinfectant in the disinfection bottle is sprayed outward, thereby disinfecting the urethral orifice, effectively reducing the bacterial load of the urethral orifice and surrounding skin, thereby reducing the risk of introducing infection during the sampling process.

[0020] 3. When the present invention is used, as the disinfectant in the disinfection bottle decreases, the weight of the disinfection bottle gradually decreases, the support spring gradually lifts the disinfection bottle upward, drives the arc block to move upward, and the tension on the connecting spring gradually decreases. Under the rebound tension of the connecting spring, the moving block is pulled to one side, driving the limit rod to slide out of the fixed hole, and finally the fixing ring is pulled upward to pull the sealing plug out of the urine cup. The sealing plug is used to seal the urine cup to prevent the inside of the urine cup from being contaminated, thereby affecting the purity of the urine sample. Through the cooperation of the disinfection component, the urine tester must first perform the disinfection step before pulling out the sealing plug and finally taking urine samples, which can improve the urine tester's trust and sense of security in the sampling process, and make the urine tester feel that the sampling process is more hygienic and professional.

The outer surface of the urination tube 303 is fixedly connected with a rubber ring 313. The top of the rubber ring 313 is fixedly installed on the bottom of the urine cup 301. The bottom of the rubber ring 313 contacts the top of the sampling tube 302. The bottom end of the urination tube 303 movably passes through the sampling tube 302 to the inside of the sealing tube 306. The tops of the first urination plate 304, the second urination plate 307 and the sealing plate 310 are all provided with four urination holes. The bottom ends of the two insertion rods 305 are movably embedded in the inside of the two slots 311 respectively. The bottoms of the four rubber blocks 312 are all in contact with the second urination plate 304. The top of the plate 307 fits together, the outer surface of the sampling tube 302 is fixedly connected to the urine outlet tube 314, one end of the urine outlet tube 314 is threadedly sleeved with a sterile sealing cover 315, the outer surface of the sampling tube 302 is fixedly installed with three fixing rods 316 near the top, the outer surfaces of the three fixing rods 316 are movably embedded in the three sliding holes 6 respectively, three fixing blocks 317 are fixedly installed on the bottom surface of the connecting groove 2, and the outer surfaces of the three fixing blocks 317 are fixedly installed with buckles 318, and the outer surface of the urine collecting cup 301 is fixedly installed inside the connecting plate 1.

[0034] In this embodiment, when in use, the three fixing rods 316 are aligned with the three sliding holes 6, and then the sampling tube 302 is pushed upward to the bottom of the rubber ring 313, so that the three fixing rods 316 pass through the three sliding holes 6 respectively, the sampling tube 302 contacts the bottom of the rubber ring 313, the bottom end of the urination tube 303 is inserted into the sealing tube 306, and the bottom ends of the two insertion rods 305 are inserted into the two slots 311. The first urination plate 304, the second urination plate 307 and the sealing plate 310 are all provided with four urination holes on the top. The four urination holes of the first urination plate 304 and the four urination holes of the second urination plate 307 are aligned, and the four urination holes at the sealing plate 310 are staggered with the urination holes of the first urination plate 304 and the second urination plate 307. The bottoms of the four rubber blocks 312 cover the four urination holes at the top of the second urination plate 307. Figure 4As shown, at this time, the sealing plate 310 and the rubber block 312 seal the second urination plate 307. Then rotate the sampling tube 302 so that the three fixing rods 316 slide in the corresponding sliding holes 6, and then snap into the buckles 318 at the corresponding positions, connecting the sampling tube 302 with the urine collecting cup 301. The insertion rod 305 is inserted into the slot 311 to limit the sealing plate 310. When the sampling tube 302 is rotated, the second urination plate 307 is driven to rotate together, and the sealing tube 306 rotates on the outer surface of the sealing plate 310 and the sealing ring 309 after the limit, and the rubber block 312 gradually leaves the urination hole of the second urination plate 307, so that the urination hole at the second urination plate 307 is aligned with the urination hole at the sealing plate 310. At this time, the sampling tube 302 is rotated. The urine cup 301, the urination tube 303, the first urination plate 304, the sealing tube 306 and the sampling tube 302 are in a connected state, which is convenient for the subsequent urine cup 301 to collect urine samples. The urine sample flows into the sealing tube 306 through the first urination plate 304 and the urination tube 303, and then flows into the sampling tube 302 through the urination hole of the second urination plate 307 aligned with the sealing plate 310. The urine cup 301 and the sampling tube 302 are spliced ​​into one piece, which is more convenient for sampling. It is not necessary to pour the urine sample in the urine cup 301 into the sampling tube 302 separately, so as to avoid urine accidentally spilling on the hands or dripping on the ground, causing hygiene problems. The urethra opening is disinfected by the disinfection component 5 to reduce bacteria, and then the sealing component 4 is removed, and the integrated sampling component 3 can be used to collect urine samples. After a proper amount of urine sample is collected in the sampling tube 302, the sampling tube 302 is rotated in the opposite direction to pull the fixing rod 316 out of the buckle 318, and the second urination plate 307 is driven to rotate in the opposite direction, so that the rubber block 312 covers the urination hole of the second urination plate 307 again, thereby sealing the second urination plate 307, and then the sampling tube 302 is moved downward to remove the fixing rod 316 from the sliding hole 6, so that the sampling tube 302 can be separated from the urine cup 301. At this time, the urine sample in the sampling tube 302 is in a sealed state. When the sampling tube 302 is inserted into the placement rack, the urine sample inside will not directly contact with the air, avoiding dust pollution and volatilization of urine components, which is conducive to improving the accuracy of the test results. It solves the problem that during the placement of the urine sampling tube, the urine sample inside is directly in contact with the air, dust will fall, causing urine sample contamination, and some urine components will also volatilize due to exposure to the air, resulting in changes in relative concentration in the sample, thereby affecting the accuracy of the test results.

A pressing rod 513 is fixedly installed on the top, and a pressing buckle plate 514 is movably sleeved on the outer surface of the pressing rod 513. One end of the piston 512 is fixedly installed inside the pressing buckle plate 514. A supporting block 515 is fixedly installed inside the connecting tube 507. A return spring 516 is fixedly connected to the bottom of the supporting block 515. A movable ball 517 is arranged at one end of the return spring 516. The top end of the pipette 505 is fixedly penetrated to the top of the disinfection bottle 504. One end of the nozzle 508 is fixedly penetrated to the inside of the pressing cover 503 from the connecting cover 502. Four telescopic rods 518 are fixedly installed at the bottom of the disinfection bottle 504 near the edge.

The bottom ends of the four telescopic rods 518 and the other ends of the four supporting springs 519 are fixedly installed on the bottom surface of the pressing bottle 501.

[0036] In this embodiment, when in use, the structure of the piston 512 is as follows Fig. 9As shown in the figure, it is composed of a piston spring, a piston rod and a stopper. After the urine cup 301 and the sampling tube 302 are installed together, the sterile patch 510 is torn off, and then the sampling tube 302 is held by hand, and the pressing buckle plate 514 is buckled and pressed, so that the piston 512 moves in the piston tube 511, so that the air quickly enters the piston tube 511, and at this time, the air near the nozzle 509 will flow quickly, the pressure will decrease, and the pressure inside the disinfection bottle 504 will increase. Under the action of high pressure, the disinfectant inside enters the pipette 505, the telescopic tube 506 and the connecting tube 507, pushing the movable ball 517 to move upward and squeezing the reset spring 5 16, and then enters the nozzle 508, and the pressing button plate 514 is pressed again, and the airflow enters the nozzle 508 and the connecting tube 507 respectively. The disinfectant is affected by the impact of the airflow, so that the movable ball 517 moves downward to close the outlet, and the disinfectant in the nozzle 508 is blown by the nozzle 509 and sprayed outward. By repeatedly pressing the pressing button plate 514, the disinfectant in the disinfection bottle 504 is sprayed outward, thereby disinfecting the urethral opening, effectively reducing the bacterial load of the urethral opening and the surrounding skin, thereby reducing the risk of introducing infection during the sampling process, which is beneficial to improving the purity of the urine sample and ensuring the accuracy of the test results.

[0037] Embodiment 3: Figure 6-Figure 7As shown, a sampling component 3 is arranged inside the connecting plate 1, a sealing component 4 is arranged inside the sampling component 3, a disinfection component 5 is arranged inside the connecting plate 1, the sealing component 4 comprises a sealing plug 401, a fixing ring 402 is fixedly installed on the top of the sealing plug 401, a fixing strip 403 is fixedly installed on the outer surface of one side of the fixing ring 402, two fixing holes 404 are provided on the outer surface of the fixing strip 403 near the bottom, two supporting rods 405 are fixedly installed on the inner wall of the pressing bottle 501 near the bottom, a moving block 406 is movably sleeved on the outer surface of the two supporting rods 405, an arc block 407 is movably embedded inside the moving block 406, the top of the arc block 407 is fixedly installed on the bottom of the disinfection bottle 504, two limiting rods 408 are fixedly installed on the outer surface of one side of the arc block 407, one end of the two limiting rods 408 are movably penetrated To the outer surface of the pressing bottle 501, the outer surfaces of the two limit rods 408 are movably embedded in the two fixing holes 404 respectively, a moving hole 7 is opened on the top of the connecting plate 1, the outer surface of the fixing bar 403 is movably embedded in the moving hole 7, a protective cover 520 is fixedly installed on the bottom of the pressing bottle 501, the bottom of the arc block 407 movably passes through the pressing bottle 501 to the inside of the protective cover 520, the outer surfaces of the two support rods 405 are movably sleeved with connecting springs 409, one end of the two connecting springs 409 is fixedly installed on the outer surface of the other side of the moving block 406, and the other ends of the two connecting springs 409 are fixedly installed on the inner wall of the pressing bottle 501, the outer surface of the pressing bottle 501 is fixedly installed on the inside of the connecting plate 1 near the moving hole 7, and the outer surface of the sealing plug 401 is movably embedded in the inside of the urine collecting cup 301.

[0038] In this embodiment, when in use, when disinfection is performed through the disinfection component 5, as the disinfectant in the disinfection bottle 504 decreases, the weight of the disinfection bottle 504 gradually decreases, and the pressure on the support spring 519 will also decrease. Under the action of the support spring 519, the disinfection bottle 504 is gradually pushed upward. When the disinfection bottle 504 moves upward, it will drive the arc block 407 to move upward together, so that the contact area between the arc block 407 and the moving block 406 gradually becomes smaller, and the tension on the connecting spring 409 will also decrease. Under the rebound tension of the connecting spring 409, the moving block 406 is pulled to one side, driving the limit rod 408 to slide out of the fixing hole 404. At this time, the connection between the fixing bar 403 and the connecting plate 1 and the pressing bottle 501 is lost. Finally, the fixing ring 402 is pulled upward to pull the sealing plug 401 out of the urine collecting cup 301, and the sampling component 3 can be used for urine sampling. The urine cup 301 is sealed by the sealing plug 401 to prevent the inside of the urine cup 301 from being contaminated, thereby affecting the purity of the urine sample. Through the cooperation of the disinfection component 5, the urine tester must first perform the disinfection step, then pull out the sealing plug 401, and finally perform urine sampling, which can improve the urine tester's trust and sense of security in the sampling process, making the urine tester feel that the sampling process is more hygienic and professional, and preventing some testers from directly pulling out the sealing plug 401 to perform urine sampling, thereby increasing the exogenous pollutants in the urine sample.

[0039] The effect and working principle of the whole mechanism are as follows: the sampling tube 302 is rotated so that the three fixing rods 316 slide in the corresponding sliding holes 6, and then snap into the buckles 318 at the corresponding positions, so that the sampling tube 302 is connected with the urine collecting cup 301, and the insertion rod 305 is inserted into the slot 311 to limit the sealing plate 310. When the sampling tube 302 is rotated, the second urination plate 307 is driven to rotate together, and the sealing tube 306 rotates on the outer surface of the sealing plate 310 and the sealing ring 309 after the limit, and the rubber block 312 leaves the urination hole of the second urination plate 307. At this time, the urine collecting cup 301, the urination tube 303, the first urination plate 304, the sealing tube 306 and the sampling tube 302 are in a connected state. By combining the urine cup 301 and the sampling tube 302 into one piece, sampling is more convenient. There is no need to pour the urine sample in the urine cup 301 into the sampling tube 302 separately, so as to avoid urine accidentally spilling on the hands or dripping on the ground, causing hygiene problems. Tear off the sterile patch 510, then hold the sampling tube 302, and press the pressing buckle plate 514 to make the piston 512 move in the piston tube 511, and the air quickly enters the piston tube 511. At this time, the air near the nozzle 509 will flow quickly, the pressure will decrease, and the pressure inside the disinfection bottle 504 will increase. Under the action of high pressure, the disinfectant enters the pipette 505, the telescopic tube 506 and the connecting tube 507, pushing the movable ball 517 to move upward. The return spring 516 is squeezed and then enters the nozzle 508. The pressing plate 514 is pressed again, and the airflow enters the nozzle 508 and the connecting pipe 507 respectively. The disinfectant is affected by the impact of the airflow, so that the movable ball 517 moves downward to close the outlet. The disinfectant in the nozzle 508 is blown by the nozzle 509 and sprayed outward. By repeatedly pressing the pressing plate 514, the disinfectant in the disinfection bottle 504 is sprayed outward, thereby disinfecting the urethral opening. As the disinfectant decreases, the weight of the disinfectant bottle 504 gradually decreases, and the support spring 519 gradually pushes the disinfectant bottle 504 upward, driving the arc block 407 to move upward together. The tension on the connecting spring 409 will also decrease. Under the rebound tension of the connecting spring 409, the moving block 406 is pulled to one side, driving the limiting rod 408 to slide out of the fixing hole 404, and finally the fixing ring 402 is pulled upward to pull the sealing plug 401 out of the urine cup 301, and the sampling component 3 can be used for urine sampling. After a proper amount of urine sample is collected in the sampling tube 302, the sampling tube 302 is rotated in the opposite direction to pull out the fixing rod 316 from the buckle 318, and the second urination plate 307 is driven to rotate in the opposite direction, so that the rubber block 312 covers the urination hole of the second urination plate 307 again, thereby sealing the second urination plate 307, and then the sampling tube 302 is moved downward, and the fixing rod 316 is removed from the sliding hole 6, so that the sampling tube 302 can be separated from the urine cup 301. At this time, the urine sample in the sampling tube 302 is in a sealed state to avoid dust pollution and volatilization of urine components.
