Description

Technical Field

[0001] The invention mainly relates to the field of medical equipment, and in particular to a container box for convenient urine detection. Background Art

[0002] Normal urine contains many crystalline and non-crystalline substances. Under saturated conditions, these substances may precipitate and form urine crystals due to changes in urine pH, temperature, metabolic disorders or lack of substances that inhibit crystal precipitation. Urine crystals sometimes appear turbid, often prompting patients to seek medical attention. The crystals that appear in urine include crystals of calcium oxalate, calcium phosphate, ammonium magnesium phosphate (triphosphate), uric acid and urate, as well as crystals precipitated from sulfonamides and other drugs.

[0003] In current medical tests, it is often necessary to detect crystal substances or non-crystalline substances in urine, or to use test strips for urine tests. For example, some patients with urinary stones or suspected patients need to take urine tests at home to check the degree of recovery of their urinary stones or to determine whether they may have urinary stones. At this time, a small, low-cost, easy-to-operate, and hygienic detection device that can be operated at home is needed. In the current technology, there is a device called a medical magnifying glass that can be used for home testing. The specific operation process is as follows: the operator first collects urine in a container, then uses a syringe to draw the urine in the container into the syringe, then pulls out the syringe needle, first installs a filter at the needle position, and then connects the needle. Then press the filter tightly and push out all the urine in the syringe. At this time, the filter will filter out some crystals in the urine. Then pull back the syringe and draw a little bit of residual concentrated urine at the needle back into the syringe. Then the remaining concentrated urine in the syringe is dropped onto a drop plate, and the drop plate is inserted into an objective lens device. Finally, the crystals in the urine on the drop plate are magnified and observed by naked eyes through the objective lens, and then judged manually. Obviously, this has the following problems:

[0004] First, the whole process has too many procedures, complicated operations, and takes a long time, which takes up too much time of the operator. This is extremely inconvenient for convenient operation at home (because after all, the operation at home is different from the professional operation of professional doctors in the hospital, and the first thing to pay attention to when operating at home is simple and convenient operation).

[0005] Secondly, it is necessary to repeatedly remove the needle, install the filter, connect the needle, drop the sample, insert the drop sample plate into the objective lens, etc. During this complicated procedure, urine may be spilled or the operator's hands and clothes may be soiled, or the objective lens device may be soiled. Not only is it difficult to clean, but the discharge is also unhygienic and easily causes bacteria infection and environmental pollution.

[0006] Third, the amount of urine filtered and concentrated is small. There is only a little residual concentrated urine at the needle tip, which results in a small sample volume, making it inconvenient for subsequent viewing and analysis, resulting in low detection accuracy.

[0007] Fourth, the filtering effect is average. The syringe is pushed out quickly, the urine is discharged quickly, and the urine is not fully filtered and deposited, making the sample filtered at the filter unrepresentative and greatly affecting the subsequent detection accuracy.

[0008] Fifth, the detection is single and the intelligence level is low. Crystal detection can only be performed with the naked eye, and manual comparison and analysis are required. Summary of the invention

[0019] As a further improvement of the present invention, more than two storage positions are provided in the test paper cavity, and a test paper is provided in each storage position.

[0020] As a further improvement of the present invention, a circle of elastic sealing ring is provided on the outer side of the inflow portion and the return portion, so that a sealing fit is formed after the corresponding insertion into the outflow port and the return port.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 6 As shown, the present invention provides a container box for convenient urine detection, including a detection chip 1 and a container box body 2, the height of the container box body 2 is between 1 cm and 30 cm, and the height and width are between 0.8 cm and 30 cm. The container box body 2 is provided with a receiving chamber 21 and a recovery chamber 22, and the detection chip 1 is provided with an inflow channel 11, a detection area 12 and a reflux channel 13 that are connected in sequence. The detection chip 1 is installed on the container box body 2 to respectively connect the receiving chamber 21 with the inflow channel 11, and the recovery chamber 22 with the reflux channel 13. The detection area 12 is provided with a filter for filtering urine and / or a test paper for detecting urine (that is, there can be only a filter, or only a test paper, or both a filter and a test paper). During the detection, the urine contained in the receiving chamber 21 flows into the detection area 12 through the inflow channel 11 and then flows into the recovery chamber 22 through the reflux channel 13 for recovery, so that the external detection instrument can read the result in the detection area 12. The specific operating principle is as follows:

[0037] The operator can directly hold urine in the receiving chamber 21, and then the urine in the receiving chamber 21 flows into the detection area 12 through the inflow channel 11. The detection area 12 is provided with a filter for filtering urine and / or a test paper for detecting urine (the specific method is described in detail below and is not repeated here). Figure 3 As shown, assuming that the detection area 12 is provided with a filter for filtering urine (such as the filter membrane described below) and a test paper for detecting urine, the urine flowing into the detection area 12 will be slowly filtered by the filter membrane, so that a good filtering effect is formed at the filter membrane, and the filtered urine will soak the test paper, causing the test paper to react. Finally, the urine will flow into the recovery chamber 22 through the reflux channel 13 to complete the recovery (such as Figure 3In the direction indicated by the arrow in the figure). During this process, except for initially putting urine into the receiving chamber 21, the operator does not need to perform any other operations, nor does anyone need to be on duty nearby. After the urine is filtered, the container box is sent to the external detection instrument to read the results in the detection area 12. The external detection instrument is provided with a special installation position for placing the container box, that is, initially putting urine into the receiving chamber 21 and placing the container box on the external detection instrument can complete the filtering and subsequent reading detection. Through the above special scientific design, it has the following technical advantages:

[0038] First, the container box for convenient urine testing of the present invention has a simple operation process and is easy to operate. In addition to putting urine into the containing chamber 21 at the beginning, the operator does not need to perform any other operations, and does not need someone to be on duty all the time. It is very convenient for family use.

[0039] Second, the container box for convenient urine detection of the present invention does not require the operator to perform any other operations except for initially placing the urine into the receiving chamber 21, and there will be no urine spilling, or soiling the operator's hands and clothes, or soiling the device. The filtered urine is directly recovered into the recovery chamber 22. After use, the operator can directly discard the entire container box, without the need to clean the detection instrument, which is not only hygienic, but also will not cause bacteria infection and environmental pollution.

[0040] Third, the container box for convenient urine testing of the present invention can hold a certain amount of urine in the accommodating cavity 21. The urine will slowly and completely flow into the detection area 12 through the inflow channel 11, and slowly penetrate and discharge, so that the sample quantity in the detection area 12 is large and the sample representativeness is strong, which greatly improves the final detection accuracy.

[0041] Fourth, the container box for convenient urine testing of the present invention has a filter for filtering urine and / or a test paper for detecting urine in the detection area 12 (that is, there may be only a filter, or only a test paper, or both the filter and the test paper), with diverse detection, strong adaptability, high intelligence, and is suitable for home use.

[0042] like Figure 4As shown, further, in a preferred embodiment, the accommodating chamber 21 is an inverted cone with an opening at the top so that urine can be quickly injected into the accommodating chamber 21 from the top, and the recovery chamber 22 is arranged outside the accommodating chamber 21, and the bottom cross section is larger than the top cross section so that urine in the reflux channel 13 can quickly flow back to the recovery chamber 22. The inverted cone can be either an inverted circular cone or an inverted square cone. As shown in the figure, the container box body 2 is square, the accommodating chamber 21 is an inverted square cone with an opening at the top, and the recovery chamber 22 is arranged outside the accommodating chamber 21. Such a special scientific design has the following technical advantages: First, the inverted cone design with an opening at the top makes the top opening area large, which is convenient for urine to be injected into the accommodating chamber 21 without overflow and pollution. Second, the design of the accommodating chamber 21 with a large volume at the top and a small volume at the bottom facilitates the continuous and smooth injection of urine into the inflow channel 11 under the action of gravity, which facilitates the full filtration and test paper reaction of the post-detection area 12, and ensures accuracy. Third, the outer space of the accommodating chamber 21 is fully utilized, so that the volume of the recovery chamber 22 is just the opposite, small at the top and large at the bottom, with a large space at the bottom, which is convenient for reducing the resistance of urine flowing back into the recovery chamber 22, so that urine can flow back into the recovery chamber 22 quickly and smoothly, that is, it will not cause blockage in the detection area 12, which is convenient for sufficient filtration of the rear detection area 12 and the reaction of the test paper, thereby ensuring accuracy.

[0043] like Figures 3 to 5 As shown, further, in a preferred embodiment, a concave outflow port 211 is provided at the bottom of the accommodating chamber 21, a concave reflux port 221 is provided at the bottom of the recovery chamber 22, a protruding inflow portion 14 is provided at the inflow channel 11 on the detection chip 1, and a protruding reflux portion 15 is provided at the reflux channel 13, and the inflow portion 14 and the reflux portion 15 are used to be inserted into the outflow port 211 and the reflux port 221 respectively, so that the detection chip 1 can be detachably limited and installed on the container box body 2. This allows people to replace different detection chips 1 and reuse a container box body 2 (the container box body 2 can be washed and reused). For example, some detection chips 1 only contain filtrate, or some detection chips 1 only contain test paper, or some detection chips 1 contain both filtrate and test paper. This greatly reduces the cost of use and is more adaptable.

[0044] Furthermore, in a preferred embodiment, the top of the recovery chamber 22 is sealed and has one or more exhaust ports 222. The top seal prevents the urine collected in the recovery chamber 22 from spilling out, and the exhaust ports 222 are provided on the top to reduce the resistance of urine flowing back into the recovery chamber 22, so that urine can flow back into the recovery chamber 22 quickly and smoothly.

[0045] like Figure 1 , Figure 2As shown, further, in a preferred embodiment, a recessed portion 23 is provided on the container box body 2 above the detection chip 1, so that an external detection instrument can be inserted into the recessed portion 23 to read the reaction result in the detection area 12 below. Figure 1 As shown, by providing the recessed portion 23, it is not necessary to pull out the detection chip 1 during detection, and the external detection instrument can easily reach into the recessed portion 23 to read the reaction result in the detection area 12 below. It is also convenient to send the container box to the external detection instrument at the beginning, and the staff does not have to be on duty next to it all the time. Later, the external detection instrument will read the result in the detection area 12.

[0046] like Figure 3 , Figure 6 As shown, further, in a preferred embodiment, a filter chamber 121 is provided in the detection area 12, and a filter membrane for filtering urine crystals is horizontally provided in the middle of the filter chamber 121 (B as shown in the figure is a filter membrane) to separate the filter chamber 121 into an upper chamber and a lower chamber, the lower chamber is used to communicate with the inflow channel 11, and the upper chamber is used to communicate with the reflux channel 13, and the top plate and bottom plate of the detection chip 1 at the filter chamber 121 are transparent plates, so that the external detection instrument can read the urine crystals on the filter membrane. In this embodiment, the filter membrane is a transparent membrane with a pore size of 10 microns, which separates the filter chamber 121, so that the urine entering the lower chamber from the inflow channel 11 can only slowly penetrate upward through the filter membrane and then enter the upper chamber above, and the area of ​​the filter membrane is large (because it is the same as the area of ​​the filter chamber 121), so that the contact area with urine is large, the filtering effect is good, more samples are retained, and the sample representativeness is strong, which greatly improves the final detection accuracy.

[0047] Furthermore, in a preferred embodiment, the detection chip 1 is provided with focusing patterns on the top plate and the bottom plate at the filter cavity 121, so as to facilitate focusing when the external detection instrument reads. In this embodiment, the focusing patterns are cross patterns provided on the top plate and the bottom plate, which facilitates focusing when the external detection instrument reads, has a good reading effect, and has a high final precision measurement accuracy.

[0048] like Figure 3 As shown, further, in a preferred embodiment, a test paper cavity 122 is provided in the detection area 12, and a test paper for urine detection is provided in the test paper cavity 122, one end of the test paper cavity 122 is used to communicate with the inflow channel 11, and the other end is used to communicate with the reflux channel 13, and the top plate and the bottom plate of the detection chip 1 at the test paper cavity 122 are transparent plates for external detection instruments to read the test paper.

[0049] Furthermore, in a preferred embodiment, more than two storage positions are provided in the test paper cavity 122, and a test paper is provided in each storage position.

[0050] Inspired by the features of the above technology, the detection chip 1 of the present invention has at least three structural forms:

[0051] One is like Figure 3 As shown, in the first specific application embodiment, a filter chamber 121 is provided in the detection area 12, and a test paper chamber 122 is also provided. The urine flowing into the channel 11 first enters the filter chamber 121 to complete the filtration, and then enters the test paper chamber 122, and then flows into the reflux channel 13 after the test paper reacts. That is, two detection functions are integrated at the same time. Second, in the second specific application embodiment, only the filter chamber 121 is provided. Third, in the third specific application embodiment, only the test paper chamber 122 is provided. Of course, in this embodiment, one or more storage positions can be set in the test paper chamber 122, and each storage position is provided with test papers. For example, different test papers can complete different tests at one time. This makes the scope of application of the present invention wide.

[0052] Furthermore, in a preferred embodiment, a circle of elastic sealing ring is disposed on the outer side of the inflow portion 14 and the return portion 15 so as to form a sealing fit after being correspondingly inserted into the outflow port 211 and the return port 221 .
