Description

Technical Field

[0001] This invention relates to the field of urine testing technology, and more particularly to a urine collection tube for urine testing. Background Technology

[0002] Urine testing is an important tool for clinical diagnosis, health screening, and disease monitoring, covering multiple application scenarios such as routine urinalysis, pathogen detection, and biochemical indicator detection. Nowadays, the demand for home self-testing and rapid on-site testing is also increasing.

[0003] Currently, the industry lacks universal urine collection tubes that can be adapted to multiple scenarios. Existing universal devices have obvious technical shortcomings: insufficient drip control precision, making it difficult to meet the drip requirements of different test reagents, thus affecting the accuracy of test results; at the same time, the opening structure is not only costly, but also cumbersome to operate and has poor adaptability, which reduces the convenience of operation for home users and also affects the efficiency of clinical testing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a urine testing collection tube that solves the technical problems of uneven drop volume control and poor compliance.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a urine testing collection tube, comprising: a collection tube body, a sponge sampling component, and a dropper cap; The collection tube is a hollow tubular structure with internal threads on its inner wall; The sponge sampling assembly includes a sponge head and a connecting tube. The sponge head is fixed to one end of the connecting tube. The outer wall of the connecting tube is provided with an external thread that matches the internal thread. The volume of the sponge head meets the small volume sampling requirements for urine testing, and the sponge head is a hydrophilic absorbent sponge. The dropper cap is sealed to the end of the collection tube away from the sponge sampling component. The top of the dropper cap has a break point, and the center of the dropper cap has a dropper hole along the axial direction. The diameter of the dropper hole is adapted to the drop volume requirement of 30-40 microliters / drop for urine testing. The connecting tube is threaded with the internal thread of the collection tube body via an external thread. When tightened, it drives the sponge head to compress into the collection tube body, causing the urine adsorbed by the sponge head to be squeezed and collected in the collection tube body. After breaking the break point, squeezing the collection tube body can cause the urine inside the tube to drip out along the drip hole.

[0006] Preferably, the diameter of the drip hole is 0.8-1.2 mm, and the inner wall of the drip hole has a smooth transition surface. The collection tube is made of elastic medical plastic material with a wall thickness of 0.3-0.5 mm. The squeezing force generated by the elastic deformation of the tube and the diameter of the drip hole work together to achieve a stable single drop volume of 30-40 microliters.

[0007] Preferably, the break point is an annular groove structure with a groove thickness of 0.1-0.2 mm, and the top of the dropper cap is provided with a raised handle for easy breakage.

[0008] Preferably, the pitch of the internal and external threads is 1.5-2.0 mm, the thread engagement stroke is 10-15 mm, and when the threads are fully tightened, the compression of the sponge head is 30%-50% of the initial length, ensuring that the urine adsorbed by the sponge head is completely squeezed into the collection tube.

[0009] Preferably, the volume of the collection tube is 2-5 ml, and the end of the connecting tube away from the sponge head is provided with a rotating handle, the outer diameter of which is larger than the outer diameter of the connecting tube.

[0010] Preferably, the sponge head is cylindrical or elliptical cylindrical in shape, with a length of 8-12 mm, a diameter of 4-6 mm, and a porosity of 60%-80%.

[0011] By employing the above technical solution, the present invention provides a urine testing collection tube, which has at least the following beneficial effects: 1. This invention, through the coordinated design of the dripping orifice and the elasticity of the tube body, precisely controls the amount of a single drop, adapts to the dripping requirements of different test reagents, avoids inaccurate test results caused by dripping deviation, and significantly improves the accuracy and repeatability of test results.

[0012] 2. This invention uses a breakable dropper cap structure to replace the traditional high-cost sealing design, which greatly reduces production costs. It can be opened without additional tools, and the operation is simple and intuitive. This not only improves the compliance of home users with self-testing, but also improves the efficiency of clinical batch testing, and is suitable for use in multiple scenarios.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example Please refer to Figures 1-6 A urine testing collection tube includes a collection tube body 1, a sponge sampling component 2, and a dropper cap 3; The collection tube 1 is a hollow tubular structure with internal threads 11 on its inner wall; The sponge sampling component 2 includes a sponge head 21 and a connecting tube 22. The sponge head 21 is fixed to one end of the connecting tube 22. The outer wall of the connecting tube 22 is provided with an external thread 221 that matches the internal thread 11. The hollow tubular structure provides storage space for urine. The internal thread 11 needs to be precisely matched with the external thread 221 of the sponge sampling component 2. The sponge head 21 can be controlled to compress through the tightening action of the thread, solving the pain point of "insufficient liquid storage of small-volume sponge heads". The volume of the sponge head 21 meets the small-volume sampling requirements of urine testing. Moreover, the sponge head 21 is a hydrophilic absorbent sponge, making the sampling process simple, quick and painless, meeting the privacy and convenience requirements of urine self-testing. The hydrophilic material absorbs liquid fully and does not easily leave urine residue, ensuring that sufficient test sample can be extracted when squeezed later. The drip cap 3 is sealed to the end of the collection tube 1 away from the sponge sampling component 2. The top of the drip cap 3 is provided with a break point 31. The center of the drip cap 3 is provided with a drip hole 32 along the axial direction. The diameter of the drip hole 32 is adapted to the drip volume requirement of 30-40 microliters / drop for urine testing. The connecting tube 22 is threaded with the internal thread 11 of the collection tube body 1 via the external thread 221. When tightened, it drives the sponge head 21 to compress into the collection tube body 1. The compatibility between the external thread 221 and the internal thread 11 directly affects the smoothness and controllability of the compression action of the sponge head 21, so that the urine adsorbed by the sponge head 21 is squeezed and gathered in the collection tube body 1. After breaking the break point 31, squeezing the collection tube body 1 can make the urine in the tube drip out along the drip hole 32. The opening method is simple and intuitive, requiring no additional tools, thus reducing the user's operating threshold. The design of the annular groove and the raised handle 33 makes breaking easier and the fracture surface is flat, avoiding scratching the hand or generating debris to contaminate the urine sample.

[0017] As a preferred technical solution in this embodiment, the diameter of the drip hole 32 is 0.8-1.2 mm. The 0.8-1.2 mm diameter, combined with the elastic medical plastic with a wall thickness of 0.3-0.5 mm, can stabilize the drip volume at 30-40 microliters / drop required for urine testing through the squeezing force generated by the moderate elastic deformation of the tube body. The smooth transition surface can reduce the flow resistance of urine and avoid residues adhering to the wall. The inner wall of the drip hole 32 is provided with a smooth transition surface. The collection tube 1 is made of elastic medical plastic with a wall thickness of 0.3-0.5 mm. The squeezing force generated by the elastic deformation of the tube body and the diameter of the drip hole 32 work together to achieve a stable single drop volume of 30-40 microliters.

[0018] As a preferred technical solution in this embodiment, the break point 31 is an annular groove structure with a groove thickness of 0.1-0.2mm. The top of the dropper cap 3 is provided with a raised handle 33 for easy breakage, which can balance the sealing stability and the ease of breakage, ensuring that it will not break accidentally during storage and transportation, and allowing users to break it easily. The raised handle 33 provides a force application point, solving the problem of difficulty in breaking due to the lack of a force application point, and the ease of operation is suitable for users of all ages. The annular groove design makes the fracture surface regular, avoids sharp edges, and improves the safety of use.

[0019] As a preferred technical solution in this embodiment, the pitch of the internal thread 11 and the external thread 221 is 1.5-2.0mm, and the thread engagement stroke is 10-15mm. When the thread is fully tightened, the compression amount of the sponge head 21 is 30%-50% of the initial length, ensuring that the urine adsorbed by the sponge head 21 is completely squeezed into the collection tube 1. The 1.5-2.0mm pitch facilitates quick tightening by the user, and the 10-15mm engagement stroke ensures that the sponge head 21 obtains sufficient compression space. The 30%-50% compression amount is the optimal range for completely squeezing out urine and avoiding damage to the sponge. Insufficient compression will result in urine residue, while excessive compression may damage the sponge structure.

[0020] As a preferred technical solution in this embodiment, the volume of the collection tube 1 is 2-5ml. The end of the connecting tube 22 away from the sponge head 21 is provided with a rotating handle 223. The outer diameter of the rotating handle 223 is larger than the outer diameter of the connecting tube 22. The sample volume required for urine testing is usually 0.5-1ml. The volume of 2-5ml can meet the sample storage needs and avoid the inconvenience of carrying due to the tube being too large. The rotating handle 223 increases the force application area, making it convenient for users to tighten the threads, especially suitable for users with less hand strength.

[0021] As a preferred technical solution in this embodiment, the sponge head 21 is cylindrical or elliptical in shape. The cylindrical or elliptical shape facilitates insertion into the sampling site. The length of 8-12mm and the diameter of 4-6mm are suitable for convenient sampling of private parts. The porosity of 60%-80% can achieve sufficient liquid absorption (absorption volume ≥1ml) in a small volume, while ensuring that urine can be quickly squeezed out when compressed. The length of the sponge head 21 is 8-12mm, the diameter is 4-6mm, and the porosity of the sponge head 21 is 60%-80%.

The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
