Description

Technical Field

[0001] The present invention relates to the technical field of medical testing instruments, and in particular to a cup cover press-type urine cup. Background Art

[0002] As one of the most important methods for clinical diagnosis and health screening, urine testing is widely used in hospital physical examination centers, community health service agencies, and in home self-testing scenarios. Currently, the mainstream urine testing tools on the market are still mainly composite products that combine a plastic urine cup with a test strip. These products achieve integrated sampling and testing by embedding a test strip with specific biochemical indicators into the internal groove of the urine cup. In actual use, the user needs to excrete urine directly into the urine cup container. When the urine liquid level reaches the preset height, the reagent area of ​​the test strip will automatically draw in the sample for analysis through capillary action.

[0003] However, this technical solution has two significant physical defects: the first is the flooding phenomenon, also known as the flooding phenomenon, that is, the urine sample forms a high-speed liquid flow under the action of gravity acceleration, impacting the test strip mounting groove, causing part of the liquid to bypass the capillary absorption area and directly flow into the test reaction area, resulting in excessive saturation of the liquid in the reagent chromatography channel; the second is the water mist interference problem, which mainly comes from the fact that when the sample volume in the urine cup exceeds the sample volume required for the test, the volatilized sample encounters the observation surface with a lower temperature and quickly condenses, forming water mist on the observation surface, which affects the reading of the test paper results. Summary of the Invention

[0004] The object of the present invention is to provide a cup cover press type urine cup, which can reduce the probability of generating flooding phenomenon and water mist phenomenon.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: The present invention provides a cup cover press type urine cup, comprising an outer cup, an inner cup, a cup cover and a sliding member; The outer cup is sleeved on the outside of the inner cup and forms a test cavity between the outer cup and the inner cup; The inner cup has a collection cavity, and the inner cup is provided with a sample channel, wherein the sample channel is configured to allow the sample in the collection cavity to enter the testing cavity when the air pressure in the collection cavity increases; The cup cover is connected to the outer cup, and a guide groove is recessed in the cup cover.

[0022] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0023] This embodiment provides a cup cover press type urine cup, such as Figure 1 and Figure 2 As shown, it includes an outer cup 1, an inner cup 2, a cup cover 3 and a sliding member 4; The outer cup 1 is sleeved on the outside of the inner cup 2 and forms a test cavity 6 between the outer cup 1 and the inner cup 2; The inner cup 2 has a collection chamber 21 and a sample passage 22 , which is configured to allow the sample in the collection chamber 21 to enter the testing chamber 6 when the air pressure in the collection chamber 21 increases. The cup cover 3 is connected to the outer cup 1, and a guide groove 31 is recessed in the cup cover 3. The outer wall of the sliding member 4 is sealed with the guide groove 31. The sliding member 4 is slidingly connected to the guide groove 31 along the depth direction of the guide groove 31. An air hole 32 connected to the collection chamber 21 is provided at the bottom of the guide groove 31.

[0024] When using the cup lid press-type urine cup provided in the above embodiment, open the cup lid 3, add the sample to the collection chamber 21 of the inner cup 2, cover the cup lid 3, press the sliding part 4 downward, and the gas in the guide groove 31 enters the collection chamber 21 through the air hole 32. The air pressure in the collection chamber 21 increases, and the sample in the collection chamber 21 can enter the test chamber 6 through the sample channel 22 of the inner cup 2 for testing. The test result can be read after a period of time.

[0025] The cup lid press-type urine cup provided in the above embodiment can control the speed of the sample entering the test cavity 6 by controlling the pressing speed of the sliding member 4, thereby reducing the probability of causing a flood phenomenon and also reducing the probability of generating water mist, without affecting the reading of the test paper results, thereby improving the reliability of the test results and facilitating use by the person to be tested. In an optional embodiment, if Figure 2 As shown, a first sealing member 7 is provided between the outer surface of the sliding member 4 and the guide groove 31 .

[0026] The provision of the first sealing member 7 can ensure good sealing between the sliding member 4 and the guide groove 31 , thereby preventing the gas in the guide groove 31 from directly overflowing from the gap between the sliding member 4 and the guide groove 31 when the sliding member 4 is pressed downward.

[0027] Specifically, if Figure 3 As shown, in order to make the installation position of the first seal 7 more stable, a first sealing groove 42 is recessed on the outer surface of the sliding member 4, and the first seal 7 is installed in the first sealing groove 42. The setting of the above-mentioned first sealing groove 42 also facilitates the installation of the first seal 7.

[0028] The number of the first sealing groove 42 can be one, two, three or more.

[0029] like Figure 3 As shown, there are two first sealing grooves 42 , and a first sealing member 7 is provided in each of the two first sealing grooves 42 .

[0030] The first sealing member 7 may be a sealing ring, and the material may be rubber.

[0031] In an optional embodiment, if Figure 2 and Figure 3 As shown, a clamping member 41 is protruded from one end of the sliding member 4 facing the bottom of the guide groove 31 . The clamping member 41 is used to pass through the air hole 32 and be clamped with the cup cover 3 .

[0032] As the sliding member 4 gradually moves downward, the gas in the guide groove 31 gradually enters the collection chamber 21, pressing the sample in the collection chamber 21 into the test chamber 6. The air pressure in the test chamber 6 also gradually increases, so the overall air pressure in the urine cup will increase. When the sliding member 4 is pressed into place, the clamping member 41 can pass through the air hole 32 and clamp with the cup cover 3 to prevent the sliding member 4 from rebounding upward under the action of air pressure.

[0033] like Figure 3As shown, the clamping member 41 includes an extension portion 411 and a clamping portion 412 connected to the extension portion 411. The clamping portion 412 has a guiding slope 4121. As it gradually moves away from the sliding member 4, the guiding slope 4121 is inclined toward the middle of the sliding member 4, so as to facilitate the clamping member 41 to pass through the air hole 32. After the clamping member 41 passes through the air hole 32, the end surface of the clamping portion 412 can abut against the bottom surface of the cup cover 3, thereby achieving the clamping connection between the clamping member 41 and the cup cover 3.

[0034] In an optional embodiment, if Figure 2 and Figure 4 As shown, the guide groove 31 is recessed toward the collecting chamber 21 , so that the guide groove 31 does not occupy additional space, thereby reducing the volume of the urine cup.

[0035] In an optional embodiment, if Figure 2 and Figure 4 As shown, the guide groove 31 is provided with a limiting surface 311 for limiting the moving distance of the sliding member 4 along the depth direction of the guide groove 31 .

[0036] When the sliding member 4 is pressed to the limit position, the sliding member 4 can abut against the limiting surface 311 , thereby limiting the sliding member 4 from continuing to move. At this time, the engaging member 41 can also be just engaged with the cup cover 3 .

[0037] In an optional embodiment, if Figure 2 As shown, a third sealing member 9 is provided between the cup cover 3 and the outer cup 1 .

[0038] The provision of the third sealing member 9 can ensure good sealing between the cup cover 3 and the outer cup 1, and prevent the gas in the outer cup 1 from escaping from the gap between the two.

[0039] Specifically, the cup cover 3 can be covered on the outside of the outer cup 1 and threadedly connected to the outer cup 1. A third sealing groove 33 can be provided at the position of the cup cover 3 corresponding to the top surface of the outer cup 1. The third sealing member 9 is installed in the third sealing groove 33. As the cup cover 3 is tightened on the outer cup 1, the top surface of the outer cup 1 gradually presses the third sealing member 9 to achieve sealing between the outer cup 1 and the cup cover 3.

[0040] The third sealing member 9 may be a sealing ring, and the material may be rubber.

[0041] In an optional embodiment, if Figure 2 As shown, a second sealing member 8 is provided between the top of the inner cup 2 and the outer cup 1 , and the test cavity 6 is located below the second sealing member 8 .

[0042] The second sealing member 8 is designed to form a sealing structure between the top of the inner cup 2 and the outer cup 1 to prevent the gas in the test chamber 6 from escaping from the gap between the inner cup and the outer cup 1 .

[0043] After opening the cup lid 3 and adding the sample to the collection chamber 21 in the inner cup 2, the sample covers the sample channel 22. At this time, the test chamber 6 is a closed space. Under the action of the air pressure in the test chamber 6, the sample in the collection chamber 21 will not enter the test chamber 6. Only after pressing the sliding member 4, the air pressure in the collection chamber 21 is greater than the air pressure in the test chamber 6, and the sample will enter the test chamber 6 through the sample channel 22.

[0044] The second sealing member 8 may be a sealing ring, and the material may be rubber.

[0045] like Figure 5 As shown, a second sealing groove 23 is recessed on the top outer wall of the inner cup 2 , and the second sealing member 8 is installed in the second sealing groove 23 . The arrangement of the second sealing groove 23 also makes it easier to install the second sealing member 8 .

[0046] Of course, the second sealing member 8 may not be provided, and the top of the inner cup 2 and the outer cup 1 may be sealed and connected by welding, bonding or clamping.

[0047] In an optional embodiment, a one-way silicone plug may be provided in the sample channel 22 , and the one-way silicone plug allows the sample in the collection chamber 21 to flow unidirectionally to the testing chamber 6 .

[0048] Specifically, the one-way silicone plug can be provided with a cutout. When the sample is added to the collection chamber 21 of the inner cup 2, the cutout is closed, which can prevent the sample from entering the test chamber 6. When the sliding member 4 is pressed, the sample pushes the cutout to open, and the sample can smoothly enter the test chamber 6.

[0049] The above-mentioned incision can be a straight incision, a cross incision, or of course, incisions of other shapes.

[0050] In other embodiments, a film may be provided in the sample channel 22. When the sample is added to the collection chamber 21 of the inner cup 2, the film blocks the sample from entering the test chamber 6. When the sliding member 4 is pressed, the sample can break through the film and smoothly enter the test chamber 6.

[0051] On the basis of the above embodiment, the outer bottom of the inner cup 2 is provided with a groove, and the bottom of the groove is provided with a sample channel 22. The above arrangement makes it easier for the sample to break through the film.

[0052] In an optional embodiment, if Figure 2 and Figure 6 As shown, the test cavity 6 includes a sample groove 61, the outer cup 1 includes an outer cup wall 11 and an outer cup bottom 12 connected to the outer cup wall 11, the outer cup bottom 12 is provided with a boss 121 protruding toward the inner cup 2, the boss 121 is against the bottom surface of the inner cup 2, and the sample groove 61 is formed between the side of the boss 121 and the outer cup wall 11, and the sample channel 22 is used to communicate with the sample groove 61.

[0053] During installation, the boss 121 can limit the inner cup 2. When the bottom surface of the inner cup 2 abuts against the boss 121, it proves that the inner cup 2 is installed in place. At this time, the sample channel 22 can be used to guide the sample to the sample slot 61.

[0054] Therefore, the setting of the boss 121 can not only limit the inner cup 2, but also form a certain space between the bottom of the inner cup 2 and the outer cup 1 to receive the sample discharged from the sample channel 22, ensuring that the sample can smoothly enter the test cavity 6.

[0055] In an optional embodiment, if Figure 6 and Figure 7 As shown, the outer cup 1 is provided with a limiting rib 13 and a test element bracket 14, both of which are connected to the inner surface of the outer cup 1. The limiting rib 13 is used to limit the circumferential position of the test element bracket 14 relative to the outer cup 1, and the test element 5 is installed on the test element bracket 14.

[0056] In the above embodiment, the test element bracket 14 can provide an installation space for the test element 5 to ensure the stability of the test element 5 during testing. The limiting rib 13 can limit the circumferential position of the test element bracket 14 relative to the outer cup 1, making the position of the test element bracket 14 more stable.

[0057] Specifically, if Figure 8 As shown, the test element bracket 14 includes an outer bracket 141 and an inner bracket 142. The outer bracket 141 is connected to the inner wall of the outer cup wall 11, and the inner bracket 142 is connected to the surface of the outer bracket 141 facing away from the outer cup wall 11 and forms multiple installation cavities with the outer bracket 141. Each installation cavity can be installed with a test element 5.

[0058] In an optional embodiment, the test elements 5 are configured in plurality, and the plurality of test elements 5 are sequentially distributed around the axis of the outer cup 1 ; the sample channels 22 are configured in plurality, and the plurality of sample channels 22 are sequentially distributed around the axis of the outer cup 1 .

[0059] The above arrangement can detect different data of the sample through multiple test elements 5 respectively, and multiple sample channels 22 can guide the sample to different test elements 5 at the same time, ensuring that the sample can be evenly distributed to each test element 5 as much as possible.

[0060] On the basis of the above embodiment, the plurality of sample channels 22 are evenly distributed relative to the plurality of test elements 5 , which can effectively ensure that the sample can be evenly distributed to each test element 5 .

[0061] In an optional embodiment, the outer cup 1 is made of a transparent material, such as glass or plastic.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
