Description

Technical Field

[0001] This invention relates to the field of sample testing technology, and in particular to a press-piston type urine cup. Background Technology

[0002] Urine testing, as an important tool in clinical medicine and health monitoring, is widely used in disease diagnosis, health screening, and daily health management. Urine cup-type products have become the most mainstream urine sampling and testing tools due to their ease of use and low cost. These products typically consist of a sampling cup and a built-in test strip. Various physiological indicators are determined by the color change that occurs when the chemical reaction zone on the test strip comes into contact with the urine sample.

[0003] Existing urine sample cups generally employ a straight-through design, where urine samples are injected directly through an opening at the top of the cup, flowing through a guide channel to contact the test strip. However, in actual use, the high-speed urine flow at the beginning of urination can cause sample splashing, with some urine potentially bypassing the designed guide path and entering the test strip mounting area directly. This unintended sample contact not only causes oversaturation of the detection area (i.e., flooding) but can also lead to cross-contamination between samples from multiple tests, severely affecting the accuracy of the results. Furthermore, when the sample volume exceeds the designed capacity, a large amount of water vapor condenses inside the sealed cup, forming a mist on the test strip surface that obstructs the detection window and interferes with the readings of the optical detection equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a piston-type urine cup to alleviate the technical problems of excessive saturation of the detection area and water mist caused by too much liquid sample in the prior art.

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] like Figures 1 to 11As shown, the press-piston type urine cup provided in this embodiment includes: an outer cup component 100, an inner cup component 200, and a piston component 300; the inner cup component 200 is disposed in the outer cup component 100, and a test chamber 10 is formed between the outer wall of the inner cup component 200 and the inner wall of the outer cup component 100, and a collection chamber 20 is formed by the inner wall of the inner cup component 200; a moving space is formed on the outer wall of the inner cup component 200, and the piston component 300 is disposed in the moving space. The piston component 300 has a sampling chamber 30, and the piston component 300 is configured to move up and down in the moving space so that the piston component 300 moves in a first position, a second position, and a third position; when the piston component 300 is in the first position, the sampling chamber 30 is connected to the collection chamber 20; when the piston component 300 is in the third position, the sampling chamber 30 is connected to the test chamber 10.

[0024] The press-piston urine cup provided in this embodiment has a piston component 300 that can move up and down. When in use, the sample is first added to the collection chamber 20, and the piston component 300 is in the first position. The collection chamber 20 is connected to the sampling chamber 30, and the sample in the collection chamber 20 flows into the sampling chamber 30. Then, the piston component 300 moves down to the third position, and the sampling chamber 30 is connected to the test chamber 10. The sample in the sampling chamber 30 flows into the test chamber 10. Since the volume of the sampling chamber 30 is fixed, the amount of sample added from the sampling chamber 30 to the test chamber 10 is appropriate each time the test is conducted, and there will be no excessive urine sample. This alleviates the technical problems of excessive liquid sample causing oversaturation of the detection area and water mist in the prior art.

[0025] Based on the above embodiments, the inner cup component 200 is further disposed inside the outer cup component 100, and a test cavity 10 is formed between its outer wall and the inner wall of the outer cup component 100. Its inner wall forms a collection cavity 20 for collecting urine samples. In the bottom region of the inner cup component 200, its outer wall is recessed to form a transition cylinder 210 structure. Multiple limiting claws 220 extend upward from the top end face of the transition cylinder 210. The multiple limiting claws 220 are spaced apart along the circumferential direction of the end face of the transition cylinder 210, and the gaps between them form a connecting hole 230. The limiting claws 220 and the transition cylinder 210 together form a moving space, which provides guiding and limiting functions for the movement of the piston component 300.

[0026] A piston component 300 is disposed within the moving space and includes an upper sealing part 310, a connecting part 320, and a lower sealing part 330. These three parts are connected in sequence and together form a sampling groove. The sampling groove forms a sampling chamber 30 for quantitatively storing urine samples flowing in from the collection chamber 20. Specifically, when the piston component 300 is in the first position, i.e., in its initial high position, the sampling chamber 30 is connected to the collection chamber 20 through the communicating hole 230 between the limiting claws 220, allowing the urine sample to enter the sampling chamber 30. When the user presses the piston component 300 downwards to move it through the second position to the third position, the sampling chamber 30 is connected to the test chamber 10, and the urine sample in the sampling chamber 30 is quantitatively released into the test chamber 10 for subsequent testing. This process achieves stepwise sample transfer, avoiding the problem of oversaturation of the test chamber 10 or even the generation of water mist due to adding too much sample at once.

[0027] It should be noted that when in the second position, the sampling chamber 30 is located at the position of the transition cylinder 210, and the transition cylinder 210 blocks the liquid in the sampling chamber 30.

[0028] To ensure that the piston component 300 maintains good sealing performance during movement and prevents urine leakage or air pressure interference, the upper sealing part 310 of the piston component 300 is provided with an upper sealing element 311, which can maintain sealed contact with the limiting claw 220 or the transition cylinder 210 during the movement of the piston component 300; the lower sealing part 330 is provided with a lower sealing element 331, which is used to seal contact with the lower structure of the transition cylinder 210, so as to maintain a sealed state at all times when the piston component 300 moves up and down, preventing liquid from flowing in an unexpected path.

[0029] To further facilitate operation, the piston assembly 300 also includes a push rod assembly 400, one end of which is fixedly connected to the top of the upper sealing part 310, and the other end extends upward for user pressing operation.

[0030] The press-type urine cup also includes a lid component 500, which is detachably connected to the outer cup component 100. This detachable connection can be achieved using a threaded connection or a snap-fit ​​connection. The lid component 500 has a recessed interior towards the inner cup component 200 to form a push rod guide groove 510. This groove accommodates the push rod component 400 and guides its vertical movement. A sealing guide groove 520 is further recessed at the bottom of the push rod guide groove 510. The push rod component 400 has a push rod sealing groove 410 for installing a push rod seal 411. A sealing connection is achieved between the push rod seal 411 and the push rod sealing groove 410, thereby preventing external contaminants from entering or urine samples from leaking during push rod movement.

[0031] To ensure the airtightness of the entire urine cup in a closed state, the outer edge of the cup lid component 500 is provided with a cup lid sealing groove 530, in which a cup lid seal 531 is installed to seal the connection gap between the cup lid component 500 and the outer cup component 100; the outer wall of the inner cup component 200 is provided with an inner cup sealing groove 240, in which an inner cup seal 241 is installed to seal the connection between the inner cup component 200 and the outer cup component 100, preventing urine from leaking from the collection chamber 20 or the test chamber 10.

[0032] In an optional embodiment, the press-piston type urine cup further includes a one-way venting component 600, specifically configured as a silicone stopper. The inner cup component 200 is provided with a mounting hole 250, and the one-way venting component 600 is installed in the mounting hole 250. The inner cup component 200 is provided with a vent hole 260, which is used to connect the collection chamber 20 and the test chamber 10. The one-way venting component 600 is located at the vent hole 260. Under normal conditions, the one-way venting component 600 can prevent liquid in the collection chamber 20 from flowing into the test chamber 10 through the vent hole 260. However, during the downward movement of the piston component 300, as the piston component 300 compresses the test chamber 10, the one-way venting component 600 can allow gas in the test chamber 10 to enter the collection chamber 20 through the vent hole 260.

[0033] To support the test elements 710 and facilitate sample collection and testing, the press-piston type urine cup also includes a mounting bracket 700. This mounting bracket 700 is disposed within the test chamber 10 inside the outer cup component 100, with its top supporting the inner cup component 200 and its bottom engaging with the bottom structure of the outer cup. The bottom of the outer cup has a sample groove 110 for collecting urine samples dripping during the test. Multiple test elements 710 can be mounted on the mounting bracket 700, with their detection ends extending into the sample groove 110 to directly contact the sample and complete the detection of urine components.

[0034] To further improve the stability of the mounting bracket 700 in the test chamber 10, a limiting rib 120 is formed on the inner wall of the outer cup component 100. The limiting rib 120 is used to fix the mounting bracket 700 to ensure that it will not shift or shake during the test, thereby ensuring the detection accuracy and stability of the test element 710. In addition, the limiting rib 120 can also support the inner cup component 200.

[0035] The push-button type urine cup provided in this embodiment has the following beneficial effects: 1. Quantitative Sampling: Quantitative transfer of urine samples is achieved through the up-and-down movement of the piston component 300. When the piston component 300 is in the first position, the sampling chamber 30 is connected to the collection chamber 20, and the urine sample in the collection chamber 20 flows into the sampling chamber 30. When the piston component 300 moves to the third position, the sampling chamber 30 is connected to the test chamber 10, and the urine sample in the sampling chamber 30 is quantitatively released into the test chamber 10. Since the volume of the sampling chamber 30 is fixed, the amount of sample added to the test chamber 10 is consistent each time, avoiding the problem of oversaturation of the detection area due to excessive sample volume.

[0036] 2. Preventing Oversaturation: Existing urine testing methods often lead to oversaturation of the testing area due to adding too much sample at once, even resulting in water mist, which affects the accuracy of the test results. This embodiment, through the quantitative transfer function of the piston component 300, ensures that the amount of sample added to the test chamber 10 each time is appropriate, effectively alleviating this problem and improving the accuracy and reliability of the test results.

[0037] 3. Simple Operation: Users simply add the urine sample to the collection chamber 20, and then move the piston component 300 up and down in the moving space by a simple pressing operation to complete the quantitative transfer and testing of the sample. This design simplifies the operation steps, reduces the difficulty of use, and allows ordinary users to easily perform urine testing.

[0038] 4. Excellent sealing performance: The piston component 300 maintains excellent sealing performance during movement, preventing urine leakage or air pressure interference. This not only ensures the purity of the sample during transfer but also prevents external contaminants from entering, ensuring a clean and stable testing environment.

[0039] 5. Compact Structure: The entire urine cup features a compact and rational design with tight fit between components, reducing its size and weight for easy carrying and storage. The compact structure also contributes to improved overall stability and durability of the device.

[0040] 6. Wide Applicability: This press-button piston urine cup is suitable for various urine testing scenarios, including home testing, medical institutions, and laboratories. Its ease of use makes it an ideal urine testing tool, helping to improve testing efficiency and user experience. Furthermore, because the collection chamber and testing chamber are separate, the sample in the collection chamber is not contaminated after the test and can be reused for retesting or other tests.

[0041] In summary, the press-piston urine cup provided in this embodiment solves the technical problems of excessive liquid sample leading to oversaturation of the detection area and water mist in the prior art through its innovative structural design and precise quantitative transfer function.
