Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a detection device. Background Technology

[0002] With the rapid development of the medical and health field, urine testing, as a simple and quick diagnostic method, has been widely used in clinical diagnosis. As one of the most commonly used tools in urine testing, test strips are favored by medical staff and patients due to their ease of operation and intuitive results. To ensure the accuracy of the test and avoid contamination of the sample by the external environment, urine test strips are usually equipped with a protective cover. The main function of this protective cover is to prevent urine contamination and to avoid environmental pollution caused by sample dripping.

[0003] In existing technologies, these protective sleeves have relatively simple functions, mainly focusing on protecting urine samples from external contamination and preventing dripping. However, with the increasing complexity of testing needs, especially in special application scenarios requiring sealed preservation and prevention of sample tampering, simple protective sleeves are no longer sufficient. These applications require protective sleeves that not only effectively protect the sample but also possess tamper-proof functionality, ensuring that the sample is not illegally opened or altered during testing, thereby guaranteeing the authenticity and reliability of the test results. Therefore, there is an urgent need in the market for a new type of test plate that can both protect the sample from contamination and prevent the protective sleeve from being reopened. Utility Model Content

[0004] The purpose of this invention is to provide a detection device to alleviate the technical problem that existing detection devices are easily tampered with.

[0005] The present invention provides a detection device comprising:

[0006] The detection unit is equipped with a data acquisition area and a first backstop structure.

[0007] The protective cover is capable of moving toward the detection unit in the closing direction and covering the collection area when it reaches its position. The protective cover is provided with a second anti-reverse structure. When the protective cover reaches its position, the first anti-reverse structure and the second anti-reverse structure are connected to prevent the protective cover from moving in the opposite direction to the closing direction.

[0008] Furthermore, of the first and second anti-reverse structures, one is an elastic element and the other is a locking hole, and the deformation and reset direction of the elastic element is set at an angle to the closing direction.

[0009] Furthermore, the elastic element includes a spring sheet, which includes a first end and a second end disposed opposite to each other along the closing direction. The first end is connected to the outer wall of the detection unit, and the second end is located outside the outer wall of the detection unit and spaced apart from the outer wall.

[0010] Furthermore, a second anti-reverse structure is provided on the inner wall of the protective cover.

[0011] Furthermore, the protective cover includes a cover body and a baffle plate, with a keyhole penetrating the inner and outer walls of the cover body;

[0012] The cover is connected to the protective cover and blocks the lock hole from the outside of the cover.

[0013] Furthermore, the protective cover can move into position in the closing direction in the first posture and cover the collection area. After moving into position in the first posture, the first stop and the second stop are misaligned to avoid the first stop and the second stop locking each other.

[0014] The protective cover can move into position in the closing direction in a second posture and cover the collection area. After moving into position in the second posture, the first stop and the second stop are connected.

[0015] Furthermore, the detection unit includes a housing and a detection element, with the detection element connected to the housing;

[0016] The display area of ​​the detection element is located inside the housing, and a visible structure is set on the housing relative to the display area so that the display area can be viewed through the visible structure.

[0017] Furthermore, the visible structure can be a transparent structure or a hollow structure.

[0018] Furthermore, the housing includes a first part and a second part, which are connected to form a space for accommodating the detection element. At least one of the first part and the second part has a receiving groove that forms the space.

[0019] Furthermore, a first backstop structure is provided on at least two different surfaces of the detection unit;

[0020] Correspondingly, a second anti-reverse structure is provided on at least two different surfaces of the protective cover, with the first anti-reverse structure and the second anti-reverse structure corresponding one-to-one.

[0021] This utility model has at least the following advantages or beneficial effects:

[0022] The detection device provided by this utility model includes: a detection unit and a protective cover. The detection unit is provided with a collection area and a first anti-reverse structure. The protective cover can move toward the detection unit in the closing direction and cover the collection area when it is in place. The protective cover is provided with a second anti-reverse structure. When the protective cover is in place, the first anti-reverse structure and the second anti-reverse structure are connected to prevent the protective cover from moving in the opposite direction to the closing direction.

[0023] When using the device, the user can collect samples using the detection unit, and then move the protective cover toward the detection unit in the closing direction so that it covers the detection unit. When the protective cover is in position (i.e., it can no longer move toward the detection unit), the first and second anti-reverse structures connect, and the two achieve a locking function, preventing the protective cover from moving in the opposite direction to the closing direction, so as to prevent the protective cover from being opened again and achieve the purpose of tamper prevention.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1 and Figure 2 As shown, the detection device provided by this utility model includes: a detection unit 1 and a protective cover 2. The protective cover 2 can be fastened to one end of the detection unit 1.

[0040] Specifically, such as Figure 2 As shown, the detection unit 1 includes a housing and detection elements 13. The housing includes a first part 11 and a second part 12 connected to each other. Receiving slots 113 can be provided on the first part 11, the number of which is the same as the number of detection elements 13. After the first part 11 is connected to the second part 12, the second part 12 and the receiving slots 113 form a space for accommodating and mounting the detection elements 13. A portion of the detection element 13 is located within the space, and a portion is located outside the space. The portion outside the space forms a collection area, while the portion inside the space has a display area. After the detection element 13 collects a sample, the display area is used to display the detection result.

[0041] The second part 12 covers a portion of the first part 11. A first anti-reverse structure is provided on the outer wall of the uncovered portion of the first part 11. The first anti-reverse structure includes a spring piece 112, which is inclined. The spring piece 112 includes a first end 1121 and a second end 1122 that are arranged opposite to each other in the closing direction. The first end 1121 is connected to the outer wall of the detection unit 1, and the second end 1122 is located outside the outer wall of the detection unit 1 and is spaced apart from the outer wall.

[0042] like Figure 3 and Figure 5 As shown, in order to make the detection unit 1 thinner, a groove 111 can be provided on the outer wall of the first part 11. The first end 1121 of the spring piece 112 is connected to the inner wall of the groove 111. The first end 1121 is lower than or flush with the opening of the first groove 111 to avoid obstructing the closing of the protective cover 2. In the free state (the test unit and the protective cover 2 are not connected), the second end 1122 is located outside the opening of the groove 111. In the initial stage of closing the protective cover 2, the inner wall of the protective cover 2 squeezes the second end 1122 so that the second end 1122 is submerged in the first groove 111.

[0043] The outer casing is configured with a visible structure relative to the display area, allowing the display area to be viewed through this structure. Specifically, the first part 11 can be made of either a transparent or opaque material. When the first part 11 is transparent, the front of the test element can face or turn away from the first part 11. When the first part 11 is opaque, the front of the test element faces away from the first part 11. In another possible implementation, when the test element faces the first part 11, the second part 12 can be made of either a transparent or opaque material. When the test element faces away from the first part 11, the observation area of ​​the structure of the second part 12 must be made of a transparent material or be openwork.

[0044] The protective cover 2 can move toward the detection unit 1 in the closing direction and cover the collection area when it is in place.

[0045] The protective cover 2 and the detection unit 1 can be separate components. In this embodiment, the protective cover 2 is not connected to the detection unit 1 when the testing unit collects samples.

[0046] The protective cover 2 is provided with a second anti-reverse structure, which can be a lock hole 211. When the protective cover 2 moves to its position, the spring piece 112 enters the lock hole 211 to prevent the protective cover 2 from moving in the opposite direction to the closing direction, thereby preventing the protective cover 2 from being opened again.

[0047] Of course, in other possible solutions, the detection unit 1 is provided with a lock hole 211, while the spring piece 112 is provided on the protective cover 2.

[0048] In this embodiment, the second anti-reverse structure is set on the inner wall of the protective cover 2. That is, after the protective cover 2 is connected to the detection unit 1 (the spring piece 112 and the lock hole 211 are connected), the lock hole 211 cannot be observed from the outside of the protective cover 2. People who do not understand the structure of the detection device cannot know the anti-reverse principle from the outer tube, nor can they open the protective cover 2 without damaging it.

[0049] For ease of processing, such as Figure 2 and Figure 4 As shown, the protective cover 2 includes a cover body 21 and a baffle plate 22. During manufacturing, a locking hole 211 penetrating through the inner and outer walls of the cover body 21 is directly machined. Then, the baffle plate 22 is connected to the protective cover 2, for example, by adhesive. The baffle plate 22 blocks the locking hole 211 from the outside of the cover body 21. Of course, in other feasible solutions, the protective cover 2 can be a single integral structure, and the locking hole 211 can be a blind hole, in which case the cover body 21 and the baffle plate 22 are unnecessary.

[0050] like Figure 6As shown, when the protective cover 2 moves toward the detection unit 1 in the second posture along the closing direction, the edge of the port of the protective cover 2 first contacts the spring piece 112 and squeezes the spring piece 112, pushing the spring piece 112 into the groove 111. The protective cover 2 continues to move until it reaches the position and covers the collection area. At the same time, the spring piece 112 moves to the locking hole 211. The spring piece 112 loses the stop of the inner wall of the protective cover 2. After restoring its deformation, the second end 1122 enters the locking hole 211. The spring piece 112 and the locking hole 211 are engaged, and the protective cover 2 cannot be pulled out in the opposite direction.

[0051] In this embodiment, as Figure 6 As shown, the protective cover 2 can also move into position along the closing direction in a first posture to cover the collection area. After moving into position in the first posture, the first stop and the second stop are offset to prevent them from locking each other. Switching from the first posture to the second posture requires the protective cover 2 to rotate 180°. That is, in the second posture, as... Figure 6 As shown, the keyhole 211 and the spring piece 112 are located on the same side, and in the first posture, as Figure 5 As shown, the locking hole 211 and the spring piece 112 are located on opposite sides. Regardless of how they slide, the spring piece 112 is stopped by the inner wall of the protective cover 2 and placed in the groove 111. At the factory, the protective cover 2 can be connected to the detection unit 1 in the first position. In this position, the protective cover 2 protects the detection element 13. Furthermore, the second end 1122 of the spring piece 112 abuts against the inner wall of the protective cover 2, increasing friction and preventing the detection unit 1 and the protective cover 2 from separating during transportation. Before using the device, the protective cover 2 is removed from the detection unit 1. After collecting a sample, the protective cover 2 is flipped over and then fastened back onto the detection unit 1 to prevent it from retracting.

[0052] Of course, in addition to the misalignment method given in this embodiment, other feasible solutions can also be adopted to achieve that the first anti-reverse structure and the second anti-reverse structure are misaligned and do not overlap when leaving the factory.

[0053] In another feasible solution, a first anti-reverse structure is provided on at least two different surfaces of the detection unit 1; correspondingly, a second anti-reverse structure is provided on at least two different surfaces of the protective cover 2. The first anti-reverse structure and the second anti-reverse structure correspond one-to-one. After the first anti-reverse structure and the second anti-reverse structure on multiple different surfaces are connected, the anti-reverse strength is increased, which increases the difficulty of preventing forced opening.

[0054] In summary, when using the device, the user can first remove the protective cover 2 from the detection unit 1, collect samples using the detection unit 1, and then rotate the protective cover 2 180° to a second posture, moving it towards the detection unit 1 in the closing direction so that it covers the detection unit 1. When the protective cover 2 has moved to its final position (i.e., can no longer move towards the detection unit), the spring clip 112 engages with the locking hole 211, and the two lock together, preventing the protective cover 2 from moving in the opposite direction to the closing direction, thus preventing the protective cover 2 from being opened again and achieving the purpose of tamper prevention. The user can observe the test results through the visible structure on the outer casing.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
