Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a pathogen sample conveying device. Background Art

[0002] In fully automatic pathogen detection equipment, the conveyance of sample test tubes is the core link for the equipment to realize continuous detection. A stable and reliable test tube transfer structure can effectively avoid problems such as sample leakage, test tube breakage and sample cross-contamination, and ensure the orderly development of the detection process. At present, the discharging structure of the sample conveying structure matched with the pathogen detector on the market only supports a single conveying path, and cannot perform multi-path shunting according to the requirements of the detection process — it cannot convey the test tubes to the upper conveying assembly to carry out detection operations as required, nor can it directly collect the sampled test tubes downward, so it is difficult to adapt to the two different working conditions of detection circulation and finished test tube collection, resulting in poor working condition adaptability.

[0003] In addition, the existing conveying structure lacks an independent built-in test tube collection structure, so that the to-be-tested test tubes after sampling cannot be uniformly and neatly stored. The scattered accumulation of test tubes will not only interfere with the normal operation of other mechanisms inside the equipment, but also affect the continuity of the whole machine's detection.

[0004] In summary, the existing conveying devices have the following problems: no multi-path shunting and discharging function, inconvenient collection of finished test tubes, and low equipment integration. Summary of the Invention

[0025] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0026] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0027] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0028] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0029] like Figures 1 to 5 As shown, according to an embodiment of the first aspect of the present invention, a pathogen sample delivery device is provided, including an outer casing 1, a support plate 2, a delivery assembly 21, a test tube output assembly 22, an ejection assembly, a flexible delivery tube 24, and a test tube collection assembly. The support plate 2 is installed inside the outer casing 1 and located in the middle of the outer casing 1. The delivery assembly 21 and the test tube output assembly 22 are both installed on the support plate 2 and located inside the outer casing 1. The test tube collection assembly is installed inside the outer casing 1 and located below the support plate 2. The test tube collection assembly is connected to the test tube output assembly 22 through the flexible delivery tube 24. The test tube output assembly 22 is used to output test tubes of the corresponding type to the delivery assembly 21 and / or the test tube collection assembly.

The support plate 2 is installed in the middle of the outer casing 1.

[0031] The test tube output component 22 is used to output test tubes of the corresponding type to the delivery component 21 and / or the test tube collection component. The corresponding type of test tube is an existing antigen extraction tube, a nucleic acid detection sampling tube, or other types of sampling tubes.

[0032] The ejection component is used to eject the corresponding test tube from the test tube output component 22 to the delivery component 21, the test tube collection component is used to collect the corresponding test tube, and the delivery component 21 is used to deliver the corresponding test tube to the subsequent detection device or to the collection box 23.

[0033] In use, the test tube output component 22 outputs the corresponding type of test tube according to the usage requirements. The test tubes can be transported to the conveying component 21, and after being transferred by the conveying component 21, the push-out component pushes the test tubes outward from the inside of the outer box 1 to complete the material discharge and transfer. Alternatively, they can be transported downward through the flexible conveying pipe 24 to the test tube collection component below the support plate 2 for uniform and orderly storage. The flexible conveying pipe 24 can buffer the impact force during the test tube transportation process and adapt to the deviation of the component installation position, thereby completing the selective transportation, fixed-point discharge and centralized collection and storage of multiple types of test tubes.

[0034] The technical effects achieved by the above embodiments are as follows: the test tube output component 22 realizes the multi-channel diversion and discharge function, and the test tube conveying path can be flexibly switched according to the needs: the test tubes can be conveyed to the conveying component 21 to cooperate with the subsequent detection station to complete the fully automatic detection of pathogens; or the test tubes can be conveyed downward to the test tube collection component through the flexible conveying tube 24 to complete the centralized collection of finished test tubes.

[0035] Meanwhile, the test tube collection component can neatly and orderly store the test tubes after sampling and testing, avoiding the test tubes from being scattered and piled up inside the equipment.

[0036] In addition, this device integrates the functions of diversion discharge, test tube conveying, test tube collection, and fixed-point ejection into the outer casing 1, and achieves upper and lower partition layout with the support plate 2 in the middle, which effectively improves the overall integration of the equipment and reduces the space occupied; with the flexible conveying tube 24 to buffer the impact of the test tube falling, it can effectively reduce the risk of breakage, sample leakage and sample cross-contamination during the test tube transportation process.
