Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a device for collecting and transferring urine samples. Background Technology
[0002] Urinalysis is one of the three routine tests in medical laboratory testing. It is crucial for the diagnosis of urinary system diseases. It can screen for problems in the urinary system, such as infections, stones, and nephritis, and can also reflect pathological changes in other systems of the body, such as diabetes and liver disease. A routine urinalysis typically includes multiple items such as urine color, clarity, pH, red blood cells, white blood cells, epithelial cells, protein, and qualitative urine glucose.
[0003] In traditional urinalysis, patients typically use a sampling cup to collect approximately 10 ml of midstream urine, which is then poured into a collection tube and sealed for testing. However, leakage and contamination are common when transferring urine from the sampling cup to the collection tube, potentially contaminating not only the sample but also the external environment. To address this issue, several novel urinalysis sample collection devices have been developed. For example, patent publication number CN204479347U discloses a midstream urine collector. The main improvement of this device is the addition of a wide-mouthed cup-shaped container to a small-diameter centrifuge tube, making sample collection much more convenient for patients and improving the accuracy of bacterial culture results while reducing the false positive rate. While this device primarily facilitates urine collection through the wide-mouthed cup-shaped container, the cap lacks a suitable connection method to the wide-mouthed cup-shaped container or urine collection tube before use and sampling, making it prone to loss during transportation and indicating a lack of compatibility. Another example is an improved urine sample collection tube published in patent CN203101127U. This device features a cap on the collection tube with a dotted line at the connection between the tube opening and the cap. After urine sample collection, the tube is broken along this dotted line to obtain an independent collection tube containing the urine sample. However, while this device includes a cap, the cap needs to be cut off for use. Furthermore, because the cap is fixed to the collection cup, opening it requires manual contact with the tube opening, posing a risk of contamination. Therefore, there is a need for a urine sample collection and transfer device that is simple in structure, low in cost, allows for complete storage and transportation, and is convenient and hygienic to use. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model designs a urine sample collection and transfer device. The device features identical threads on the upper and lower parts of the collection tube, as well as identical threads inside the collection tube cap and collection cup. During transportation and storage, the collection tube cap is attached to the bottom of the collection tube, and the collection cup is attached to the top of the collection tube, ensuring the device's integrity and compatibility. All components are tightly connected, preventing loss. After collection, the user unscrews and discards the collection cup at the upper end of the collection tube, and unscrews the collection tube cap from the lower end and installs it on the upper end, ensuring convenience and hygiene during the collection process.
[0005] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a urine sample collection and transfer device, comprising: a collection cup, a collection tube, and a collection tube cap; the collection cup is threaded to the upper end of the collection tube, and the collection tube cap is threaded to the lower end of the collection tube;

[0007] The upper part of the collection cup is a funnel-shaped cup body with a large upper port diameter and a small lower port diameter. A connecting section is fixedly connected to the lower end of the cup body. The connecting section is a hollow cylindrical structure and has an internal thread that can cooperate with the external thread of the collection tube.
[0008] The inside of the collection tube cap is provided with an internal thread that can mate with the external thread of the collection tube; the thread type, size and depth are the same at the upper end, lower end of the collection tube, inside the collection cup and inside the collection tube cap;
[0009] Furthermore, the top of the collection tube is open, the upper part of the collection tube is a liquid storage section, and the lower part is a sediment section, the diameter of the sediment section is smaller than the diameter of the liquid storage section.
[0010] Furthermore, a liquid-blocking edge is provided on the inner side of the connection between the collection cup body and the connecting section, and an inclined angle is provided on the inner side of the liquid-blocking edge;
[0011] Furthermore, the outer side of the collection tube is provided with graduations;

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1
[0028] This utility model discloses a urine sample collection and transfer device, comprising: a collection cup 2, a collection tube 1, and a collection tube cap 3; the collection cup 2 is threaded to the upper end of the collection tube 1, and the collection tube cap 3 is threaded to the lower end of the collection tube 1.
[0029] The outer surface of the collection tube 1 is cylindrical, with the outer diameter of both the upper and lower ends being consistent, facilitating its mating with the threaded structure of the collection cup 2 and the collection tube cap 3. An external thread is designed on the outer side of the upper end of the collection tube 1, and a similar external thread is also designed on the outer side of the lower end of the collection tube 1, for matching the internal thread of the collection tube cap 3.
[0030] The upper part of the collection cup 2 is a funnel-shaped cup body 201 with a larger upper diameter for easy urine collection, while the lower diameter helps control the urine flow into the collection tube 1 and prevents splashing. A connecting section 202 is fixedly connected to the lower end of the cup body 201. The connecting section 202 is a hollow cylindrical structure with an internal thread that mates with the external thread of the collection tube 1, ensuring a tight connection between the collection cup 2 and the collection tube 1.
[0031] The uniform thread design allows the collection tube cap 3 to be easily unscrewed from the lower end of the collection tube 1 and then tightened back onto the upper end of the collection tube 1 to seal the collection tube 1 and ensure the integrity and safety of the sample. Example 2
[0032] In this embodiment, the internal structure of the collection tube 1 allows it not only to store urine samples but also to better separate and collect precipitates during centrifugation. The diameter of the sedimentation section 104 is smaller than that of the collection cup 2103, which facilitates the deposition of precipitates in the urine within the sedimentation section 104 under centrifugal force during subsequent centrifugation, thereby achieving effective separation of urine and precipitates. Furthermore, the smaller diameter of the sedimentation section 104 also helps reduce the movement of precipitates during transportation and storage, ensuring the stability and integrity of the precipitates. Example 3
[0033] In this embodiment, a liquid-blocking edge 204 is provided on the inner side of the connection between the cup body 201 and the connecting section 202 of the collection cup 2, and a slope is provided on the inner circle of the liquid-blocking edge 204. The main function of this liquid-blocking edge 204 is to cover the edge of the top of the collection tube 1 during the urine sample collection process, to prevent urine from soaking into the top edge of the collection tube 1, and to ensure the hygiene of the collection tube 1 opening. In addition, since there is a slope inside the liquid-blocking edge 204, it ensures that urine accumulates in the collection cup 2 to a minimum, reducing the possibility of spillage when the collection cup 2 is discarded, and facilitating subsequent operations. Example 4
[0034] In this embodiment, the outer side of the collection tube 1 is provided with scale markings 105. These scale markings 105 provide users with an intuitive reference, enabling users to accurately control the amount of urine sample when collecting urine samples. By observing the liquid level and the scale markings 105, users can pour out excess urine from the collection cup 2. Example 5
[0035] In this embodiment, anti-slip textures are provided on the outer side of the connecting section 202 of the collection cup 2 and the outer side of the collection tube cap 3. These anti-slip textures provide additional friction when the user rotates the collection cup 2 and the collection tube cap 3, preventing the collection cup 2 and the collection tube cap 3 from being difficult to unscrew due to the smoothness of the device. A handle 203 is provided at the upper end of the collection cup 2. The concave structure 205 inside the handle 203 provides the user with a better grip when holding the collection cup 2, improving the stability of the grip. Example 6
[0036] In this embodiment, the specific usage process and working principle of this device are as follows:
[0037] After discarding the initial urine, the user holds the handle 203 of the collection cup 2, with the upper end of the collection cup 2 facing upwards, and suspends the entire device below the urethra to collect the middle section of urine. Collection stops at the opening of the collection tube 1. After observing the liquid level and the graduation mark 105, the excess urine is poured out, ensuring that the urine volume is around 10ml. After sampling, the collection cup 2 is rotated off and discarded. The collection tube cap 3, which is installed at the bottom of the collection tube 1, is then unscrewed and tightened onto the upper opening of the collection tube 1. After ensuring the device is airtight, the sample can be sent for testing.
[0038] In summary, this utility model discloses a urine sample collection and transfer device, comprising: a collection cup, a collection tube, and a collection tube cap; the collection cup is threaded to the upper end of the collection tube, and the collection tube cap is threaded to the lower end of the collection tube; the device has identical external threads on the upper and lower parts of the collection tube, and identical internal threads in the collection tube cap and the collection cup. During transportation and storage, the collection tube cap is assembled at the bottom of the collection tube, and the collection cup is assembled at the top of the collection tube, ensuring the integrity and compatibility of the device, and the tight connection between the various components, preventing any loss; after collection, the user unscrews and discards the collection cup at the upper end of the collection tube, and unscrews the collection tube cap from the lower end of the collection tube and installs it at the upper end of the collection tube, ensuring convenience and hygiene during the collection process. Furthermore, the device has a simple structure, is easy to produce and transport, and has excellent commercialization prospects.
