Description

Technical Field

[0001] This invention relates to the field of urine testing technology, and specifically discloses a sealed urine sampling device and sampling method for urine testing. Background Technology

[0002] Urine testing is a medical diagnostic method that includes routine urinalysis, detection of formed elements in urine (such as red blood cells and white blood cells), quantitative determination of protein components, and urine enzyme assays. Urine testing is of great value in clinical diagnosis, assessing treatment efficacy, and predicting prognosis. Urine testing requires the use of sampling equipment to obtain the urine sample, often using midstream urine, as initial and final urine samples are easily contaminated by the urethra, leading to inaccurate results. Currently, the collection process typically involves the test subject going to the restroom to collect their urine sample in a plastic cup, then placing the cup on a designated shelf or pouring the urine into a designated test tube. After collection, the sample is sent to the laboratory for analysis. However, due to poor sealing, the urine can come into contact with multiple people and the environment during transfer and retrieval. Furthermore, urine can come into contact with the outer wall of the test tube during retrieval, easily causing contamination.

[0003] To address the issue of poor sealing in existing urine collection and sampling devices, a patent with authorization number CN110215237B discloses a sealed urine collection device for collecting urine and transferring it into a test tube. The sealed urine collection device includes a main body, a top cover, and a flow guiding assembly. The main body includes a receiving cavity for storing urine, with an inlet for collecting urine and an outlet for discharging urine. The top cover is connected to the main body and sealably covers the inlet. The flow guiding assembly includes a flow guiding element and a sealing element. The flow guiding element has a drainage channel communicating with the outlet. The sealing element is rotatable and sealed at the outlet, and also has a guide channel for guiding the urine in the receiving cavity to the drainage channel. The sealing element can rotate under force, connecting the two ends of the guide channel to the receiving cavity and the drainage channel respectively, allowing the urine stored in the receiving cavity to flow into the test tube. This invention not only seals and stores urine but also prevents contamination of the test tube's outer wall during urine transfer.

[0004] Based on the above search and combined with existing technology, it was found that although the existing urine collection devices can solve the sealing problem to a certain extent, they still have the following shortcomings: (1) Before the positioning groove and the test tube are connected, since the entrance of the test tube is not completely sealed, some urine will flow along the positioning groove onto the surface of the test tube, thus causing the test tube to be contaminated; (2) Since the test tube is fixed by relying solely on the spring force, when the weight of the urine inside the test tube gradually increases, the spring force is insufficient to support the test tube, which can easily cause the test tube to fall off and cause urine to spill. Therefore, it is urgent to propose a sealed urine collection and sampling device and sampling method to improve the above problems. Summary of the Invention

[0005] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that because the inlet of the test tube is not completely sealed, some urine will flow onto the surface of the test tube, causing test tube contamination. Also, when the weight of urine inside the test tube gradually increases, the spring force is insufficient to support the test tube, which can easily cause the test tube to fall off and cause urine to spill.

[0006] To address the above problems, this invention provides a sealed urine sampling device, comprising: A sampling tube, wherein an annular support and a support platform are respectively installed at the bottom and on the inner wall of the sampling tube; The urine outlet tube has a mounting groove at the bottom center of the sampling tube for fixing the urine outlet tube; The support platform has a first through hole in the middle and a first spherical groove at the top of the first through hole. A first sealing ball sleeve is attached to the inner wall of the first spherical groove and a first ball is fixed to the inner wall of the first sealing ball sleeve.

[0008] The present invention is further configured such that the support platform divides the interior of the sampling tube into a urine receiving chamber and a urine storage chamber from top to bottom, and the urine receiving chamber is connected to the sampling nozzle, and the urine storage chamber is connected to the second through hole. The top and bottom of the support platform are designed as funnels facing opposite directions.

[0009] The present invention is further configured such that a sealing gasket ring is fixedly installed at the bottom of the sampling tube, and the sealing gasket ring is attached to the top of the inner wall of the annular support and the top of the outer wall of the urine outlet tube, and the bottom of the inner wall of the sampling tube is designed as a slope.

[0010] The present invention is further configured such that the lifting assembly includes a pull rod fixed to the top of the first sphere, and the top of the pull rod is fixed with an irregular frame that is equidistantly arranged at 180 degrees, and the bottom end of the irregular frame is fixed with the same actuating frame structure sleeved on the outer wall of the sampling cylinder. The bottom of the irregular frame and the support platform are both provided with a reset assembly, and the reset assembly is provided with an anti-permeability assembly.

[0011] The present invention is further configured such that the actuating frame structure includes guide sleeves fixed at equal intervals to the outer wall of the sampling cylinder, and a fixing rod is inserted into the inner wall of each guide sleeve. The top of the fixing rod is fixed with the same first fixing ring. The bottom end of the irregular frame is fixedly connected to the first fixing ring. A handle bar located below the grip plate is fixed to one side of the top of the first fixing ring. A handle glove is fixed to one side of the outer wall of the handle bar. The bottom of the fixing rod is fixed with the same second fixing ring.

[0012] The invention is further configured such that the reset assembly includes second insertion holes equally spaced on the top of the support platform, and each of the irregular-shaped frames has a rod inserted into the second insertion hole at its bottom. Each rod has a movable disc at its bottom, and each movable disc has a second spring fixedly installed at its bottom and at the bottom of the second insertion hole.

[0013] The present invention is further configured such that the anti-permeability component includes a connecting cylinder fixed to the top of the second insertion hole, and a fixing ring is fixed to the top of the outer wall of the insertion rod, and a corrugated sleeve is fixed to the bottom of the fixing ring and the top of the connecting cylinder.

[0014] The invention is further configured such that the clamping and fixing assembly includes mounting cavities equidistantly formed at the bottom of the sampling cylinder and the top of the inner wall of the annular support, and the annular support is also provided with movable grooves equidistantly connected to the mounting cavities, the positions of the movable grooves corresponding to the middle position of the mounting cavities. The bottom of the second fixing ring is fixed with equidistantly distributed traction rods, and the bottom of the traction rods passes through the movable grooves and extends into the interior of the mounting cavity. The bottom end of the traction rod is fixed with a mounting base, and both ends of the mounting base are rotatably connected with traction plates. The bottom ends of the traction plates are rotatably connected with movable plates, and one end of each movable plate is provided with a first insertion hole. The inner wall of each first insertion hole is inserted with a clamping post. One end of each clamping post is fixedly installed with a first spring at one end of the first insertion hole, and the other end of each clamping post is fixedly installed with a protective pad. Guide grooves are provided on both sides of the bottom of the mounting cavity, and a guide block is fixedly slidably disposed in the guide groove at one bottom end of each movable plate.

[0015] A sealed urine sample collection method, applied to a sealed urine sample collection device, includes the following steps: Step 1: The subject holds the handle with one hand and lifts the entire urine collection and sampling device to collect a midstream urine sample; Step 2: The subject carefully observes the entire device. Once the urine collection chamber is full of urine, collection can be stopped, and the entire device should be held firmly. Step 3: Hold the handle and handle sleeve with one hand, press your thumb on the grip plate, and squeeze the handle to lift the entire lifting assembly and actuation frame structure. At this time, the first ball and the second ball rise synchronously, changing the first and second through holes from a closed state to a conducting state, and then to an open and closed state, so that the urine in the urine receiving cavity flows into the urine storage cavity. After the urine has flowed out, gradually release the handle and use the reset component to reset the first and second balls, sealing the urine storage cavity. Step 4: When the test tube is ready to be removed, the examiner places it over the urine tube and attaches it to the sealing ring. Repeat step 3 to simultaneously open the first and second through holes, allowing urine to flow into the test tube through the second through hole. At the same time, the position of the clamping post and the protective pad in the clamping and fixing assembly can be changed so that the protective pad is tightly attached to the surface of the test tube for clamping and fixing the test tube.

[0016] In summary, by adopting the above structure, the present invention has the following advantages compared with the prior art: 1. This invention, through the cooperation of multiple sealing ball sleeves, multiple balls, and a reset component, can form an effective sealing structure at the first and second through holes, ensuring that the inside of the urine storage cavity is sealed, effectively preventing urine leakage, ensuring the purity and accuracy of the sample, helping to improve the reliability of urine testing, and the good sealing performance can reduce the influence of external factors on urine samples, prevent air from entering and causing sample deterioration, and reduce the possibility of cross-infection.

[0017] 2. This invention divides the interior of the sampling tube into a urine collection chamber and a urine storage chamber by means of a support platform, thereby realizing the division of different functional areas. Its funnel-shaped design helps the flow and collection of urine. The reasonable layout between the various components inside the device helps to maintain the stability and reliability of the seal and reduce the risk of equipment failure. Compared with plastic cups, the entire device still has the benefit of being reusable after disinfection and cleaning.

[0018] 3. In the process of urine extraction, the shape of the clamping and fixing components is simultaneously adjusted by the lifting component, so that the clamping column and the protective pad are tightly attached to the surface of the test tube in a 360-degree circumferential state. This securely clamps the test tube and tightly attaches it to the sealing gasket ring, enhancing the sealing performance at the connection between the bottom of the sampling tube and the test tube, preventing urine leakage and test tube contamination. The clamping force also fixes the test tube, ensuring its stability and preventing the test tube from falling off due to the increased weight of the urine, thus preventing urine spillage.

[0019] 4. In this invention, through the cooperation of multiple sealing ball sleeves and multiple balls, when there is excess urine, the excess urine can be released along the second through hole during the process of opening the urine storage cavity, without pouring out from the top of the device, thus avoiding the problem of contaminating the surface of the device.

[0020] 5. In this invention, a ring-shaped support is used to support the entire device, making it easy to place the entire device flat on the table and isolating the urine tube from the table, thus avoiding contamination caused by the urine tube contacting the table. Attached Figure Description

The lifting and lowering control of the first sealing ball sleeve 16 and the second sealing ball sleeve 21 is realized through the cooperation of the pull rod 25, the irregular frame 3 and the like in the lifting assembly, thereby adjusting the flow and sealing state of urine. A clamping and fixing assembly 9 is provided on the annular support 10 and at the bottom of the lifting assembly. The clamping and fixing assembly 9 includes mounting cavities 903 that are equidistantly opened at the bottom of the sampling cylinder 1 and the top of the inner wall of the annular support 10.

The position of the movable slots 902 corresponds to the middle position of the mounting cavities 903. The bottom of the second fixing ring 8 is fixed with equidistantly distributed traction rods 901. The bottom of the traction rods 901 passes through the movable slots 902 and extends into the interior of the mounting cavities 903.

The position of the clamping and fixing component 9 is adjusted synchronously by the lifting component, so that the clamping column 908 and the protective pad 909 are tightly attached to the surface of the test tube in a 360-degree circumferential state, thereby firmly clamping the test tube and tightly attaching it to the sealing gasket ring 22, enhancing the sealing performance at the connection between the bottom of the sampling cylinder 1 and the test tube, preventing urine leakage and test tube contamination, and also fixing the test tube by clamping force to ensure the stability of the test tube, avoiding the phenomenon of the test tube falling off due to the increase of urine weight, and preventing urine spillage.

[0027] In this invention, the support platform 14 divides the interior of the sampling cylinder 1 from top to bottom into a urine receiving chamber 13 and a urine storage chamber 18. The urine receiving chamber 13 is connected to the sampling nozzle 2, and the urine storage chamber 18 is connected to the second through hole 29. The top and bottom of the support platform 14 are designed as funnels facing opposite directions. Figure 2 , Figure 3 and Figure 4 As shown, the funnel-shaped design of the support platform 14 facilitates the flow and collection of urine.

[0028] In this invention, the reset assembly 23 includes second insertion holes 2301 equidistantly spaced on the top of the support platform 14, and each of the irregularly shaped frames 3 has a rod 2302 fixedly inserted into the second insertion hole 2301 at its bottom. Each rod 2302 has a movable disc 2303 fixedly attached to its bottom, and each movable disc 2303 has a second spring 2304 fixedly installed at its bottom and the bottom of the second insertion hole 2301. Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, this is used to restore the lifting assembly to its original position after operation, ensuring the normal operation of the equipment.

[0029] In this invention, the anti-permeability component 24 includes a connecting cylinder 2401 fixed to the top of the second insertion hole 2301, and a fixing ring 2403 is fixed to the top of the outer wall of the insertion rod 2302. A corrugated sleeve 2402 is fixed to the bottom of the fixing ring 2403 and the top of the connecting cylinder 2401, as shown below. Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the corrugated sleeve 2402 ensures the sealing of the second socket 2301, preventing urine from seeping into the second socket 2301.

[0030] A sealed urine sample collection method, applied to a sealed urine sample collection device, includes the following steps: Step 1: The subject holds the handle 4 with one hand and lifts the entire urine collection and sampling device to collect a midstream urine sample; Step 2: The subject carefully observes the entire device. Once the urine collection chamber 13 is filled with urine, the collection can be stopped, and the entire device should be held firmly. Step 3: Hold the handle bar 5 and handle sleeve 6 with one hand, press your thumb on the grip plate 4, and squeeze the handle bar 5 to lift the entire lifting assembly and the actuating frame structure. At this time, the first ball 15 and the second ball 20 rise synchronously, changing the first through hole 27 and the second through hole 29 from a state of simultaneous closure to a state of simultaneous conduction, and then to a state of one open and one closed, so that the urine in the urine receiving cavity 13 flows into the urine storage cavity 18. After the urine has flowed out, gradually release the handle bar 5, and use the reset action of the reset assembly 23 to reset the first ball 15 and the second ball 20, sealing the urine storage cavity 18. Step 4: When the test tube is ready to be removed, the examiner inserts the test tube onto the urine outlet tube 19 and attaches it to the sealing gasket ring 22. Repeat step 3 to simultaneously open the first through hole 27 and the second through hole 29, so that the urine flows into the test tube along the second through hole 29. At the same time, the positions of the clamping post 908 and the protective pad 909 in the clamping and fixing assembly 9 can be changed so that the protective pad 909 is tightly attached to the surface of the test tube for clamping and fixing the test tube.

[0031] In summary, the working principle of this invention is as follows: During use, the examinee holds the handle plate 4 with one hand and lifts the entire urine collection and sampling device to collect mid-section urine samples. Once the urine collection chamber 13 is full of urine, collection can be stopped, and the entire device should be held firmly. At this time, the examinee holds the handle rod 5 and handle sleeve 6 with one hand, pressing their thumb on the handle plate 4, and forcefully grips the handle rod 5, causing the entire lifting assembly and actuating frame structure to rise. This causes the second spring 2304 inside the reset assembly 23 to extend. At this time, the first ball 15, the first sealing ball sleeve 16, the connecting rod 17, the second ball 20, and the second sealing ball sleeve 21 rise synchronously, changing the first through hole 27 and the second through hole 29 from a simultaneously closed state to a simultaneously open state, and then to an open and closed state, allowing the urine in the urine collection chamber 13 to flow into the urine storage chamber 18. After the urine has finished flowing, gradually release the handle 5. The second spring 2304 will reset the first sealing ball sleeve 16 and the second sealing ball sleeve 21, sealing the urine storage chamber 18. When removing the test tube, the examiner will put the test tube onto the urine outlet tube 19 and place it under the sealing gasket ring 22. Continue to hold the handle 5 and adjust the height of the first sealing ball sleeve 16 and the second sealing ball sleeve 21 in conjunction with the lifting assembly and the actuating frame structure. This will simultaneously open the first through hole 27 and the second through hole 29, allowing the urine to flow into the test tube along the second through hole 29. At the same time, the tilt of the traction plate 904 inside the clamping and fixing assembly 9 can be changed, causing the movable plate 905 to move and adjusting the position of the clamping column 908 and the protective pad 909, so that the protective pad 909 is tightly attached to the surface of the test tube, thereby clamping and fixing the test tube.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
