Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and in particular to a urine collection tube technology. Background Technology

[0002] Currently, fully automated urine analyzers and urine sediment analyzers are widely used in medical institutions in my country, automatically collecting urine samples using sampling needles for subsequent testing. Previously, laboratory personnel had to manually unscrew the caps of each collection tube. This sample pretreatment method not only increased the low-level, repetitive work of technicians but also increased the risk of occupational exposure for medical staff. Existing caps are not securely fixed and easily fall off. The sealing of the collection tubes is also insufficient. Therefore, designing a snap-on, cap-free, disposable urine collection tube can avoid these problems, reduce the low-level, repetitive work of technicians, and facilitate patient sampling.

[0003] However, existing urine collection tubes cannot be adapted to automated production and assembly, which greatly increases their cost. Therefore, a new type of urine collection tube that can adapt to automated production and meet the requirements of automated assembly is needed. Summary of the Invention

[0004] This utility model provides a novel urine collection tube that is adapted to the standards of automated production and automated assembly.

[0005] The first aspect of this utility model discloses a novel urine collection tube, which includes the following components: a cap, a puncture membrane, a fixing ring, and a tube body; wherein: The puncture membrane is a thin film with thickened edges, and the thickened part is a pressure-resistant ring. The thickness ratio of the pressure-resistant ring to the film is 50-200. The cover is divided into an upper part and a lower part. The lower part is threaded for engagement with the tube body. The upper part is a limiting cavity configured to accommodate the puncture tool and the fixing ring. An annular protrusion is located at the edge of the limiting cavity. The annular protrusion is at a distance h1 from the top of the limiting cavity and h2 from the bottom of the limiting cavity. The value is 2-10; there is an annular hollow platform at the junction of the upper and lower parts of the cover; a puncture membrane is disposed on the annular hollow platform and the interior of the annular hollow platform has a certain upward curvature; The fixing ring is configured to be embedded inside the annular hollow platform to fix the puncture membrane; and the fixing ring has an asymmetrical structure, including rounded corners and right angles. The top of the tube is provided with a thread that matches the cover, and an annular protrusion is provided below the thread.

[0006] In a preferred embodiment, the thread is an intermittent structure.

[0007] In a preferred embodiment, the film thickness is 0.001-2 mm.

[0008] In a preferred embodiment, the diameter of the upper part of the cover is less than or equal to the diameter of the lower part.

[0009] In a preferred embodiment, a warning mark is drawn on the outer wall of the urine collection tube.

[0010] In a preferred embodiment, the pressure-resistant ring has the same shape as the fixed ring.

[0011] In a preferred embodiment, the bottom of the tube may be nipple-shaped, conical, or semi-circular.

[0012] In a preferred embodiment, the lower part of the cover is provided with anti-slip stripes.

[0013] In a preferred embodiment, the puncture membrane has a slightly upward or downward curvature.

[0014] The advantages of this novel urine collection tube are: 1) The urine collection tube of this utility model does not require manual cap removal and can be directly put into the machine for testing, which greatly reduces the workload of the testing personnel, improves their work comfort, and enhances their medical protection level. 2) The novel urine collection tube of this utility model has a limiting ring configured on the cover, which allows the urine collection tube to be fixed before the fixing ring is configured on the top of the cover, so that it can be directly adapted to the automated assembly process. 3) The thread of the urine collection tube body of this utility model is an intermittent thread, which has the advantage that it can be fully adapted to the automated process and will not be stuck in the production line.

[0015] The specification of this utility model contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which should be considered as described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description

[0020] Example This utility model discloses a method such as Figures 1-6 The novel urine collection tube shown is suitable for automated processes, compatible with automated urine analyzers or automated urine sediment analyzers, and suitable for automated production and assembly in automated production lines. The urine collection tube includes: a cap 1, a puncture membrane 2, a tube body 5, and a retaining ring 3; The puncture membrane 2 is a thin film with thickened edges, and the thickened part is a pressure-resistant ring 8. The thickness ratio of the pressure-resistant ring to the film is 50-200. The cover 1 is divided into an upper part and a lower part. The lower part is provided with threads 6 for engaging with the tube body 5. The upper part is a limiting cavity 4, which is configured to accommodate the puncture membrane 2 and the fixing ring 3. An annular protrusion 12 is disposed inside the limiting cavity 4.

[0025] Optionally, in one embodiment, the exterior of the body is provided with anti-slip stripes.

[0026] Alternatively, in one embodiment, the puncture membrane has a slightly upward or downward curvature.

[0027] Specifically, in the assembly process of the urine collection tube of this utility model, the cap and the tube body are first assembled. Then, the puncture membrane 2 is placed on the annular hollow platform 10 inside the cap 1. In this embodiment, the inner side of the annular hollow platform 10 is configured with a slightly upward arc, making it an annular groove. The pressure-resistant ring 8 of the puncture membrane 2 matches the shape of the annular groove of the hollow platform 10, so that during the assembly process, the pressure-resistant ring 8 is embedded in the annular hollow platform 10. Then, the fixing ring 3 is placed in the limiting ring 4 of the cap 1, so that the cap 1 is in a pre-fixed state. Then, the fixing ring 3 is pressed into the pressure-resistant ring 8 on the annular platform 10 through the assembly line process, thereby completing the fixation.
