Description

Technical Field

[0001] This utility model relates to the technical field of virus detection devices, specifically a multi-virus centralized detection device. Background Technology

[0002] Existing virus test kits can only detect one virus at a time. If multiple viruses need to be detected, samples need to be added to different virus test kits for testing. This involves many steps, is time-consuming, and can easily lead to missed detections.

[0003] Chinese Publication No. CN212375260U discloses a multi-virus centralized detection device, comprising: a box body, multiple virus detection cards, and a box lid. Multiple slots are evenly arranged on the side wall of the box body, each slot facing the center of the box body. Each virus detection card can be inserted into a separate card, with its ends clustered together. Each virus detection card has a sample application hole at one end and an observation hole in the middle. The box lid is fastened to the upper part of the box body, and a sample application groove is provided in the middle of the box lid. Multiple through holes are provided at the bottom of the sample application groove, the lower end of each through hole leading directly above the sample application hole on a virus detection card. This multi-virus centralized detection device allows users to add samples to the sample application holes on various virus detection cards targeting different viruses at once for centralized detection, simplifying the detection process and reducing the likelihood of missed detections.

[0004] The above scheme can perform simultaneous detection of multiple different viruses at one time, simplifying the detection steps. However, in actual operation, each test requires the use of six virus detection cards. If one virus detection card is missing, the through hole at the position where the virus detection card is not installed will be unobstructed, causing the test sample to flow out through this through hole. Therefore, it is impossible to perform detection operations of less than six viruses as needed, resulting in weak detection operation flexibility. Based on this, a multi-virus centralized detection device is provided. Utility Model Content

[0005] The purpose of this invention is to provide a multi-virus centralized detection device in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-virus centralized detection device, comprising a detection box and a virus detection card, wherein the virus detection card comprises a detection card body, a sample application hole, and an observation hole, wherein the sample application hole and the observation hole are arranged horizontally and sequentially on the upper surface of the detection card body, and the detection box comprises a box body, a detection chamber, an insertion interface, a hexagonal sample application groove, a guide oblique hole, a hexagonal storage groove, and a hexagonal central column;

[0007] The detection chamber is formed inside the main body of the box, and six insertion interfaces are provided. The six insertion interfaces are evenly distributed in a ring on the outside of the main body of the box and are connected to the detection chamber.

[0008] The hexagonal sample loading slot and the hexagonal storage slot are respectively opened at the upper and lower ends of the main body of the box. There are six flow guiding oblique holes. The six flow guiding oblique holes are distributed in the middle of the six sides of the bottom of the hexagonal sample loading slot and extend through to the top of the inner side of the detection chamber. The hexagonal central column is fixed to the top middle of the inner wall of the hexagonal storage slot.

[0009] When the main body of the test card is inserted into the inner side of the test chamber through the plug interface, the lower port of the sample dispensing hole is aligned with the lower port of the guide oblique hole. The guide oblique hole is used to guide the test sample in the hexagonal sample dispensing groove to the sample dispensing hole on each test card main body.

[0010] An automatic sealing assembly is provided on the inner side of the hexagonal storage slot and the inner side of the detection chamber. The automatic sealing assembly includes a sealing unit and a locking unit.

[0011] The sealing unit is used to seal the lower port of the guide oblique hole when the main body of the detection card is not inserted into the detection chamber;

[0012] The locking unit is used to lock and limit the detection card body when it is inserted into the detection chamber.

[0013] As a further improvement of this utility model: the sealing unit includes a 7-shaped sealing block and a W-shaped spring sheet;

[0014] The vertical portion of the 7-shaped sealing block is arranged inside the hexagonal storage groove, and the horizontal portion of the 7-shaped sealing block extends into the inner side of the detection chamber. The upper surface of the horizontal portion of the 7-shaped sealing block is attached to the top of the inner wall of the detection chamber and forms a blockage on the lower port of the guide oblique hole.

[0015] The W-shaped spring is distributed between the vertical part of the 7-shaped sealing block and the end face of the hexagonal central column, and the two ends of the W-shaped spring are respectively bonded and fixed to the vertical part of the 7-shaped sealing block and the end face of the hexagonal central column. The W-shaped spring is used to provide thrust for the sealing state of the 7-shaped sealing block.

[0016] As a further improvement of this utility model: the locking unit includes a notch and a side-tilted T-shaped elastic block;

[0017] The notch is located on the outer bottom of the main body of the box and is connected to the detection chamber. One end of the horizontal part of the side-inverted T-shaped elastic block is fixed to one end of the inner wall of the notch, and the top of the vertical part of the side-inverted T-shaped elastic block protrudes to the inner side of the detection chamber.

[0018] The lower surface of the detection card body is provided with a locking hole. When the detection card body is inserted into the detection chamber, the top of the vertical part of the side-tilted T-shaped elastic block is engaged with the locking hole to lock the position of the detection card body.

[0019] As a further improvement of this utility model: the 7-shaped sealing block, W-shaped spring sheet, notch groove, and side-inverted T-shaped elastic block are provided in six sets, and are respectively aligned with the positions of the six insertion interfaces and the flow guide oblique holes.

[0021] As a further improvement of this utility model: the inner end face trajectory of the detection chamber is hexagonal, and the side length of the hexagon matches the width of the detection card body, and the height of the detection card body matches the height of the inner wall of the detection chamber.

[0022] As a further improvement of this utility model: the top horizontal height of the detection chamber is lower than the bottom horizontal height of the hexagonal sample loading groove, and the top opening size of the sample loading hole is larger than the size of the lower port of the guide inclined hole.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] By setting up an automatic blocking component, the 7-shaped blocking block corresponding to the area where no virus detection card is installed can block the flow guide orifice. During the detection operation, the blocked flow guide orifice will intercept the test sample and will not affect the detection operation. In this way, the number of test items can be selected as needed for a single test, making the overall detection operation more flexible. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 In this embodiment of the utility model, a multi-virus centralized detection device includes a detection box 1 and a virus detection card 2. The virus detection card 2 includes a detection card body 201, a sample application hole 202, and an observation hole 203. The sample application hole 202 and the observation hole 203 are arranged horizontally on the upper surface of the detection card body 201. The detection box 1 includes a box body 101, a detection chamber 102, an insertion interface 103, a hexagonal sample application groove 104, a guide oblique hole 105, a hexagonal storage groove 106, and a hexagonal central column 107.

[0034] The detection chamber 102 is formed inside the box body 101. Six insertion interfaces 103 are provided. The six insertion interfaces 103 are evenly distributed in a ring on the outside of the box body 101 and are connected to the detection chamber 102.

[0035] Hexagonal sample loading slots 104 and hexagonal storage slots 106 are respectively opened at the upper and lower ends of the main body 101 of the box. Six flow guiding oblique holes 105 are provided. The six flow guiding oblique holes 105 are distributed in the middle of the six sides of the bottom of the hexagonal sample loading slot 104 and extend through to the top of the inner side of the detection chamber 102. The hexagonal central column 107 is fixed to the top middle of the inner wall of the hexagonal storage slot 106.

[0036] When the test card body 201 is inserted into the inner side of the test chamber 102 through the insertion interface 103, the sample dispensing hole 202 is aligned with the lower port of the guide inclined hole 105. The guide inclined hole 105 is used to guide the test sample in the hexagonal sample dispensing groove 104 to the sample dispensing hole 202 on each test card body 201.

[0037] An automatic sealing component 3 is provided on the inner side of the hexagonal storage slot 106 and the inner side of the detection chamber 102. The automatic sealing component 3 includes a sealing unit and a locking unit.

[0038] The sealing unit is used to seal the lower port of the guide oblique hole 105 when the detection card body 201 is not inserted into the detection chamber 102;

[0039] The locking unit is used to lock and limit the detection card body 201 when it is inserted into the detection chamber 102;

[0040] The sealing unit includes a 7-shaped sealing block 301 and a W-shaped spring 302;

[0041] The vertical part of the 7-shaped blocking block 301 is arranged inside the hexagonal storage groove 106, and the horizontal part of the 7-shaped blocking block 301 extends into the inner side of the detection chamber 102. The upper surface of the horizontal part of the 7-shaped blocking block 301 is attached to the top of the inner wall of the detection chamber 102 and forms a blockage on the lower port of the guide oblique hole 105.

[0042] W-shaped spring clips 302 are distributed between the vertical part of the 7-shaped sealing block 301 and the end face of the hexagonal central post 107. The two ends of the W-shaped spring clips 302 are respectively bonded and fixed to the vertical part of the 7-shaped sealing block 301 and the end face of the hexagonal central post 107. The W-shaped spring clips 302 are used to provide thrust for the sealing state of the 7-shaped sealing block 301.

[0043] The locking unit includes a notch 303 and a side-tilting T-shaped elastic block 304;

[0044] The notch 303 is opened on the outer side of the bottom of the box body 101 and is connected to the detection chamber 102. One end of the horizontal part of the side-tilted T-shaped elastic block 304 is fixed to one end of the inner wall of the notch 303, and the top of the vertical part of the side-tilted T-shaped elastic block 304 protrudes to the inner side of the detection chamber 102.

[0045] The lower surface of the detection card body 201 is provided with a locking hole 204. When the detection card body 201 is inserted into the detection chamber 102, the top of the vertical part of the side-tilted T-shaped elastic card block 304 is engaged in the locking hole 204 to lock the position of the detection card body 201.

[0046] There are six sets of 7-shaped sealing blocks 301, W-shaped spring pieces 302, notches 303, and side-tilted T-shaped elastic blocks 304, which are respectively aligned with the positions of six insertion interfaces 103 and flow guide oblique holes 105.

[0047] In this embodiment, the operating steps for using this detection device are as follows:

[0048] First, take the virus test card 2 corresponding to the test item and insert the test card body 201 into a connector 103 (with the sample application hole 202 and observation hole 203 facing upwards and the locking hole 204 facing downwards). During this process, the test card body 201 will first contact and compress the side-inverted T-shaped elastic block 304, causing the side-inverted T-shaped elastic block 304 to bend downwards, thus allowing the test card body 201 to smoothly enter the test chamber 102. Afterwards, the test card body 201 will contact and push the lateral part of the 7-shaped blocking block 301, causing the 7-shaped blocking block 301 to bend downwards. The sealing block 301 contracts and squeezes the W-shaped spring 302 to further contract. Finally, the front end of the detection card body 201 fits against the inner wall end face of the detection chamber 102. At this time, the locking hole 204 is aligned with the vertical part of the side-inverted T-shaped elastic block 304. The side-inverted T-shaped elastic block 304 resets under its own elastic force, and the top of the vertical part of the side-inverted T-shaped elastic block 304 is inserted into the locking hole 204 to fix the position of the detection card body 201. At the same time, the sample feeding hole 202 is aligned with the lower port of the guide inclined hole 105, while the observation hole 203 is still outside the detection box 1.

[0049] After installing the multiple virus detection cards 2 that need to be tested in sequence, the subsequent testing operations can be carried out. It should be noted that the number of tests per test can be selected from 2 to 6 as needed (when performing a test, the test can be performed directly through a single virus detection card 2). When there are fewer than 6 tests, the 7-shaped blocking block 301 corresponding to the area where no virus detection card 2 is installed will block the flow guide oblique hole 105.

[0050] Next, the test sample is dripped into the hexagonal sample application groove 104. The test sample will flow into the six guide orifices 105. Among them, the blocked guide orifices 105 will be blocked, while the other unblocked guide orifices 105 can guide the test sample to the sample application holes 202 on each virus test card 2. After waiting for 10-15 minutes at room temperature, the user can judge the virus contained in the test sample through the observation hole 202 on each virus test card 3. (It should be noted that the virus test card 2 is a commonly used test card on the market. Its detection principle and structure are mature technologies that are widely used in virus detection. Therefore, the internal structure and detection principle of the virus test card will not be described in detail here.)

[0051] With the cooperation of the above-mentioned components, the number of items to be tested in a single test can be selected as needed, making the overall testing operation more flexible.

[0052] Please refer to this carefully. Figure 3 , Figure 6The top of the vertical part of the side-tilted T-shaped elastic block 304 facing the outside of the box body 101 has an arc-shaped structure, and the bottom of the vertical part of the side-tilted T-shaped elastic block 304 facing the outside of the box body 101 has an inward concave surface.

[0053] In this embodiment: the arc-shaped structure at the top of the vertical part of the side-inverted T-shaped elastic card block 304 makes it easier to press and deform the side-inverted T-shaped elastic card block 304 downward when the detection card body 201 contacts the arc surface, thus ensuring the smooth operation of the detection card body 201.

[0054] By using the concave surface at the bottom of the vertical part of the side-tilted T-shaped elastic block 304, it is easy to press the concave surface of the side-tilted T-shaped elastic block 304 to move it, thereby releasing the locking state of the side-tilted T-shaped elastic block 304 on the detection card body 201, thereby realizing the removal operation of the detection card body 201.

[0055] It should be noted that the bottom of the vertical part of the side-tilting T-shaped elastic block 304 is higher than the lower surface of the main body of the box 101, and will not affect the horizontal placement of the main body of the box 101.

[0056] Please refer to this carefully. Figures 1-4 The inner end face of the detection chamber 102 is hexagonal, and the side length of the hexagon matches the width of the detection card body 201. The height of the detection card body 201 matches the height of the inner wall of the detection chamber 102.

[0057] The top horizontal height of the detection chamber 102 is lower than the bottom horizontal height of the hexagonal sample loading groove 104, and the top opening size of the sample loading hole 202 is larger than the size of the lower port of the guide inclined hole 105.

[0058] In this embodiment: This structure ensures that the detection card body 201 will not become loose when installed inside the detection chamber 102, and the inclined guide hole 105 facilitates the flow of the detection sample towards the sample loading hole 202.

[0059] The top opening of the sample loading hole 202 is larger than the lower port size of the guide orifice 105, which allows for complete reception of the incoming test sample.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
