Abstract
Description
Technical Field
[0001] This invention belongs to the field of testing and analysis technology, and in particular relates to a sampling tube for adaptive release of preservatives. Background Technology
[0002] Routine urine testing plays a crucial role in animal GLP (Good Laboratory Practice) experiments. Urine samples contain a large number of biomarkers, providing key information about animal physiological status, drug metabolism, and toxic effects. Urine analysis can perform semi-quantitative / qualitative detection of one or more chemical indicators in animal urine. Common indicators include dry chemical components (pH, specific gravity (SG), protein (PRO), glucose (GLU), ketone bodies (KET), etc.) and formed element analysis (leukocytes, erythrocytes, casts, crystals, etc.), which can provide reference for clinical testing and diagnosis, as well as non-clinical drug research.
[0003] For animal experiments, since animal urination is not under human control and its excretion is random, it is difficult to collect, send, and test urine within a specified time after it is produced. Therefore, selecting an appropriate dosage of preservative is an effective way to ensure urine stability. However, there are still some potential problems with the addition of urine preservatives, which affect the accuracy of urine test results, as follows:
[0004] 1. Preservative addition compliance issues: Thymol solution is colorless and transparent, making it impossible to visually determine whether a preservative has been added during collection or testing. If the operator forgets to add a preservative, the urine sample will become unstable and deteriorate, affecting the accuracy of the results.
[0005] 2. Timeliness of preservative addition: Failure to add preservatives promptly after animal urine collection will also affect the stability of the urine sample. Utility Model Content
[0006] This invention addresses the problem in existing technologies where the absence or delayed addition of preservatives affects test results. It provides a sampling tube with an adaptive preservative release mechanism. The tube incorporates a second cavity connected to the first cavity, extending from the bottom of the first cavity. A solid preservative is placed within this second cavity. When urine is collected using the sampling tube, the solid preservative immediately contacts and automatically releases and disperses upon contact with the urine, thus resolving the issue of insufficient or delayed preservative addition affecting test results and ensuring the accuracy of the results.
[0007] The technical solution adopted in this utility model is:
[0008] An adaptive release preservative sampling tube includes a tube body and a cap. The interior of the tube body is a first cavity. An independent second cavity is provided from the bottom of the first cavity. From bottom to top, corresponding parts of the second cavity are connected to the first cavity. From the bottom of the second cavity, a solid preservative is laid inside the second cavity.
[0009] Furthermore, starting from the bottom of the tube, one or more grooves are formed on the inner wall of the tube along its height direction; the groove area is the second cavity.
[0010] Furthermore, starting from the bottom of the tube, one or more grooves are formed on the inner wall of the tube in a spiral upward direction; the groove area is the second cavity.
[0011] Furthermore, starting from the bottom of the tube, multiple grooves are formed on the inner wall of the tube along its own circumference; the area inside the groove is the second cavity.
[0012] Furthermore, starting from the bottom of the tube, one or more sets of partition components protruding from the inner wall of the tube are formed along its own height direction on the inner sidewall of the tube; the partition component includes two partition protrusions, and the area between the two partition protrusions is the second cavity.
[0013] Furthermore, starting from the bottom of the tube, one or more sets of partition components protruding from the inner wall of the tube are formed on the inner sidewall of the tube in a spiral upward direction; the partition component includes two partition protrusions, and the area between the two partition protrusions is the second cavity.
[0014] Furthermore, starting from the bottom of the tube, multiple sets of partition components protruding from the inner wall of the tube are formed in the circumferential direction on the inner sidewall of the tube; each partition component includes two partition protrusions, and the area between the two partition protrusions is the second cavity.
[0015] Furthermore, starting from the bottom of the tube body, one or more medicine-holding tubes are formed along the height direction in the area of the tube body that does not directly contact the inner wall; the upper and lower ends of the medicine-holding tubes are connected, and a notch is formed on the tube wall of the medicine-holding tube; the notch starts at the lower end of the medicine-holding tube and ends at the upper end of the medicine-holding tube; the internal area of the medicine-holding tube is the second cavity.
[0016] Furthermore, graduations are formed on the outer wall of the tube along its height direction.
[0017] Furthermore, the second cavity is provided with a matching receiving groove, and the solid anti-corrosion agent is laid in the receiving groove.
[0018] The beneficial effects of the utility model are:
[0019] This invention designs a sampling tube that adaptively releases preservatives. Specifically, a second cavity, connected to the first cavity, is set inside the tube from the bottom of the first cavity, and a solid preservative is laid in the second cavity. When urine is collected by the sampling tube, the solid preservative immediately comes into contact with the urine and is automatically released and dispersed, thereby solving the problem of the test results being affected by the absence or failure to add the preservative in a timely manner, and ensuring the accuracy of the test results.

[0034] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0035] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.
[0036] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings. Example 1
[0037] This embodiment provides a sampling tube for adaptive release of preservatives, referring to... Figures 1 to 2 It consists of a tube body 1 and a cap 2. The tube body 1 and the cap 2 are mostly made of plastic (such as PE, PP, PVC, etc.) by injection molding, which is low in cost and corrosion resistant. The top of the tube body 1 is open and transparent; the cap 2 is placed on top of the open end of the tube body 1.
[0038] Inside the tube body 1, starting from the bottom of the tube body 1, a set of partition components 3 protruding from the inner wall of the tube body 1 are formed along its own height direction on the inner wall of the tube body 1; the partition component 3 includes two parallel and oppositely arranged partition protrusions 31; the groove-shaped area formed between the two partition protrusions 31 in the same group is the second cavity 7; the area inside the tube body 1 other than the second cavity 7 is the first cavity 6; the first cavity 6 and the second cavity 7 are connected.
[0039] A solid preservative is placed inside the second cavity 7; the solid preservative can be thymol, etc. In specific operation, isopropanol or the like can be used as a solvent to prepare a 10% thymol solution by mass. After the thymol solution is introduced into the second cavity 7, it is quickly air-dried to remove the solvent. The remaining thymol adheres to the inner wall of the second cavity 7, thus obtaining the solid preservative.
[0040] In this embodiment, to ensure the accuracy of the internal volume of the tube body 1, when forming the scale on the outer wall of the tube body 1 along its own height direction, the volume occupied by the separating protrusion 31 and the solid anti-corrosion agent needs to be removed.
[0041] In this embodiment, the length of the dividing protrusion 31 can be set according to requirements. For example, along the height direction of the tube body 1, the lower end of the dividing protrusion 31 starts at the bottom of the first cavity 6 (i.e., the connection between the inner sidewall and the inner bottom wall), and the upper end of the dividing protrusion 31 ends at the top of the first cavity 6 (i.e., the open end). Alternatively, along the height direction of the tube body 1, the lower end of the dividing protrusion 31 starts at the bottom of the first cavity 6 (i.e., the connection between the inner sidewall and the inner bottom wall), and the upper end of the dividing protrusion 31 ends at a position 5-10 mm from the top of the first cavity 6 (i.e., the open end).
[0042] When collecting urine using the sampling tube in this embodiment, after the collected urine to be tested is added to the first cavity 6, since the first cavity 6 and the second cavity 7 are interconnected, the solid preservative is quickly and automatically released and dispersed after contact with the urine.
[0043] Compared to the traditional method of adding preservatives after sampling, the sampling tube of this embodiment contains the preservatives before adding the urine to be tested, which prevents operators from forgetting to add the preservatives. Furthermore, the preservatives begin to be released and dispersed immediately after the urine to be tested is added to the sampling tube, ensuring the effectiveness of timely addition of preservatives to the liquid to be tested.
[0044] Meanwhile, from bottom to top, the corresponding parts of the second cavity are all connected to the first cavity; as the urine level in the sampling tube changes, the solid preservative at the corresponding urine level in the second cavity is automatically released and dispersed, thereby ensuring that the quality of the preservative in the urine is roughly uniform, which further helps to ensure the accuracy of the test results. Example 2
[0045] Reference Figure 3 This embodiment provides a sampling tube for adaptive release of preservatives, which differs from Embodiment 1 in that: on the inner side of the tube body 1, starting from the bottom of the tube body 1, a set of partition components 3 protruding from the inner side wall of the tube body 1 are formed along the spiral upward direction on the inner side wall of the tube body 1; the partition component 3 includes two parallel and oppositely arranged partition protrusions 31; the groove-shaped area formed between the two partition protrusions 31 in the same group is the second cavity 7. Example 3
[0046] Reference Figure 4 This embodiment provides a sampling tube for adaptive release of preservatives, which differs from Embodiment 1 in that: on the inner side of the tube body 1, starting from the bottom of the tube body 1, five sets of partition components 3 protruding from the inner sidewall of the tube body 1 are formed along their own circumferential direction on the inner sidewall of the tube body 1; the five sets of partition components 3 are evenly distributed along the height direction of the inner sidewall of the tube body 1; the partition component 3 includes two parallel and oppositely arranged partition protrusions 31; the groove-shaped area formed between the two partition protrusions 31 in the same set is the second cavity 7.
[0047] In this embodiment, because there is a certain height difference between adjacent separator components 3, the quality of the dispersed preservative in the urine will fluctuate as the urine level changes. This fluctuation can be reduced by increasing the number of separator components 3 and decreasing the distance between adjacent separator components 2. On the other hand, if the quality of the preservative has no impact on the test results, the sampling tube is perfectly suitable when the adjacent separator components 3 are at a certain distance.
[0048] In this embodiment, when the partition component 3 is formed along the circumference of the tube body 1, the bottom of the second cavity 7 refers to the groove-shaped area formed by the lowest set of partition components 3 inside the tube body 1. Example 4
[0049] Reference Figures 5-6 This embodiment provides a sampling tube for adaptive release of preservatives, which includes a tube body 1 and a cap 2. The tube body 1 and the cap 2 are mostly made of plastic (such as PE, PP, PVC, etc.) by injection molding, which is low in cost and corrosion resistant. The top of the tube body 1 is open and transparent; the cap 2 is placed on top of the open end of the tube body 1.
[0050] Inside the tube body 1, starting from the bottom of the tube body 1, a groove 4 is formed on the inner wall of the tube body 1 along its own height direction; the groove area formed by the groove 4 is the second cavity 7; the area inside the tube body 1 other than the second cavity 7 is the first cavity 6; the first cavity 6 and the second cavity 7 are connected.
[0051] A solid preservative is placed inside the second cavity 7; the solid preservative can be thymol, etc. In specific operation, isopropanol or the like can be used as a solvent to prepare a 10% thymol solution by mass. After the thymol solution is introduced into the second cavity 7, it is quickly air-dried to remove the solvent. The remaining thymol adheres to the inner wall of the second cavity 7, thus obtaining the solid preservative.
[0052] In this embodiment, to ensure the accuracy of the internal volume of the tube body 1, when forming the scale on the outer wall of the tube body 1 along its own height direction, it is necessary to calculate the increased volume of the groove 4 and remove the volume occupied by the solid anti-corrosion agent.
[0053] In this embodiment, the length of the groove 4 can be set according to requirements. For example, along the height direction of the tube body 1, the lower end of the groove 4 starts at the bottom of the first cavity 6 (i.e., the connection between the inner sidewall and the inner bottom wall), and the upper end of the groove 4 ends at the top of the first cavity 6 (i.e., the open end). Alternatively, along the height direction of the tube body 1, the lower end of the groove 4 starts at the bottom of the first cavity 6 (i.e., the connection between the inner sidewall and the inner bottom wall), and the upper end of the groove 4 ends at a position 5-10 mm from the top of the first cavity 6 (i.e., the open end).
[0054] When collecting urine using the sampling tube in this embodiment, after the collected urine to be tested is added to the first cavity 6, since the first cavity 6 and the second cavity 7 are interconnected, the solid preservative is quickly and automatically released and dispersed after contact with the urine.
[0055] Compared to the traditional method of adding preservatives after sampling, the sampling tube of this embodiment contains the preservatives before adding the urine to be tested, which prevents operators from forgetting to add the preservatives. Furthermore, the preservatives begin to be released and dispersed immediately after the urine to be tested is added to the sampling tube, ensuring the effectiveness of timely addition of preservatives to the liquid to be tested.
[0056] Meanwhile, from bottom to top, the corresponding parts of the second cavity are all connected to the first cavity; as the urine level in the sampling tube changes, the solid preservative at the corresponding urine level in the second cavity is automatically released and dispersed, thereby ensuring that the quality of the preservative in the urine is roughly uniform, which further helps to ensure the accuracy of the test results. Example 5
[0057] Reference Figure 7 The sampling tube for adaptive release of preservative provided in this embodiment differs from that in embodiment 4 in that: on the inner side of the tube body 1, starting from the bottom of the tube body 1, a groove 4 is formed on the inner side wall of the tube body 1 in a spiral upward direction; the groove area formed by the groove area of the groove 4 is the second cavity 7; the area inside the tube body 1 other than the second cavity 7 is the first cavity 6; the first cavity 6 and the second cavity 7 are connected. Example 6
[0058] Reference Figure 8 The sampling tube for adaptive release of preservatives provided in this embodiment differs from that in embodiment 4 in that: five grooves 4 are formed on the inner wall of the tube body 1 along its own circumference, starting from the bottom of the tube body 1; the distance between each groove 4 is the same along the height direction of the inner wall of the tube body 1; the groove-shaped area formed by the groove area of the groove 4 is the second cavity 7; the area inside the tube body 1 other than the second cavity 7 is the first cavity 6; the first cavity 6 and the second cavity 7 are connected.
[0059] In this embodiment, since there is a certain height difference between adjacent grooves 4, the quality of the preservative dispersed in the urine will fluctuate as the urine level changes. This fluctuation can be reduced by increasing the number of grooves 4 and decreasing the distance between adjacent grooves 4. On the other hand, if the quality of the preservative has no impact on the test results, the sampling tube is perfectly suitable when the adjacent grooves 4 are at a certain distance.
[0060] In this embodiment, when the groove 4 is formed along the circumference of the tube body 1, the bottom of the second cavity 7 refers to the groove area of the lowest groove 4 inside the tube body 1. Example 7
[0061] Reference Figure 9 The sampling tube for adaptive release of preservatives provided in this embodiment differs from that in Embodiment 1 in that: on the inner side of the tube body 1, starting from the bottom of the tube body 1, three sets of partition components 3 protruding from the inner sidewall of the tube body 1 are formed along their own height direction on the inner sidewall of the tube body 1; the partition component 3 includes two parallel and oppositely arranged partition protrusions 31; the three sets of partition components 3 are adjacent to each other, so adjacent partition components 3 share a common partition protrusion 31; the groove-shaped area formed between the two partition protrusions 31 in the same set is the second cavity 7; the area inside the tube body 1 other than the second cavity 7 is the first cavity 6; the first cavity 6 and the second cavity 7 are connected.
[0062] Simultaneously, a matching receiving groove 5 is provided within each second cavity 7. The outer periphery of the receiving groove 5 is consistent with the size of the groove area formed between the two separating protrusions 31, and it can be removed from the two separating protrusions 31. Solid corrosion inhibitor is laid inside the receiving groove 5, and then the receiving groove 5 and the solid corrosion inhibitor are laid as a whole into the second cavity 7.
[0063] Specifically, in preparing the solid preservative, isopropanol or similar solvents are used to prepare a 10% thymol solution. The thymol solution is then introduced into the receiving tank 5 and quickly air-dried to remove the solvent. This greatly improves operational convenience, as it is not affected by the confined space within the tube 1, and the solvent evaporates quickly. After the preservative has dried in the receiving tank 5, it is inserted into the middle area of the separating protrusion 31, and subsequent testing can be performed according to the procedure in Example 1. Example 8
[0064] Reference Figure 10 The sampling tube for adaptive release of preservatives provided in this embodiment differs from that in embodiment 4 in that: on the inner side of the tube body 1, starting from the bottom of the tube body 1, three grooves 4 are formed on the inner wall of the tube body 1 along its own height direction; the three grooves 4 are evenly distributed along the circumferential direction of the inner wall of the tube body 1; the groove-shaped area formed by the groove area of the groove 4 is the second cavity 7; the area inside the tube body 1 other than the second cavity 7 is the first cavity 6; the first cavity 6 and the second cavity 7 are connected.
[0065] Simultaneously, a matching receiving groove 5 is provided in each second cavity 7. The outer periphery of the receiving groove 5 is consistent with the size of the groove area of the groove 4, and it can be removed from the two separating protrusions 31. Solid corrosion inhibitor is laid in the receiving groove 5, and then the receiving groove 5 and the solid corrosion inhibitor are laid as a whole into the second cavity 7.
[0066] Specifically, in preparing the solid preservative, isopropanol or similar solvents are used to prepare a 10% thymol solution. The thymol solution is then introduced into the receiving tank 5 and quickly air-dried to remove the solvent. This greatly improves operational convenience, as it is not affected by the confined space within the tube 1, and the solvent evaporates quickly. After the preservative has dried in the receiving tank 5, it is inserted into the middle area of the separating protrusion 31, and subsequent testing can be performed according to the procedure in Example 4.
