Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a detection instrument for early screening of lung cancer. Background Technology

[0002] Lung cancer is a malignant tumor originating from the bronchial mucosa or glands of the lungs. It is one of the fastest-growing malignant tumors in terms of incidence and mortality, posing a significant threat to public health and life. Currently, the cure rate for advanced lung cancer is relatively low; the earlier lung cancer is detected, the higher the cure rate. According to the Chinese Society of Clinical Oncology (CSCO) guidelines for lung cancer diagnosis and treatment, the main diagnostic methods for lung cancer include blood biopsies, ultrasound, and pathological biopsy. These methods all have drawbacks to varying degrees, including low sensitivity, invasiveness, long processing times, and high costs.

[0003] Existing technologies, such as the EVs automated detection instrument for early lung cancer screening disclosed in CN220709039U, involve setting up a reaction chamber, a sample chamber, and a reagent chamber. Samples from the sample chamber and reagents from the reagent chamber flow into the reaction chamber to react. Color signals acquired by a color sensor are used to determine the nature of the reaction, thereby achieving early lung cancer screening and meeting the needs of patient self-examination. However, in the above technology, after the detection is completed, a vacuum pressure pump is used to remove the liquid from the reaction chamber. This process cannot completely clean the residual liquid on the inner wall of the reaction chamber. Consequently, during subsequent tests, new reagents or samples flow into the reaction chamber and mix with the residual liquid from the previous test, affecting the accuracy of the detection.

[0004] Therefore, a detection device for early lung cancer screening is needed to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a detection instrument for early screening of lung cancer. By eliminating the design of the vacuum pressure pump in the prior art, the reaction cell is set as a box that can slide out of the detection instrument body, so as to facilitate manual cleaning of the residual liquid on the inner wall of the reaction cell and ensure the accuracy of the re-test.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a detection instrument for early lung cancer screening, including an instrument body. The instrument body is provided with a sample pool, a reagent pool, and a reaction pool located between the sample pool and the reagent pool. The reaction pool is a box with an open top. The instrument body is provided with a chute for accommodating the reaction pool. The chute is connected to the outside of the instrument body. The reaction pool can slide out of the instrument body along the chute. The sample pool and the reagent pool are connected to the top wall of the chute through pipes.

[0007] Furthermore, the height of the chute is greater than the height of the reaction tank, a baffle is fixedly installed on the top wall of the chute, the outer wall of the baffle is in contact with the inner wall of the reaction tank, and a bottom plate is slidably connected to the bottom wall of the chute. Vertically sliding the bottom plate can allow the reaction tank to be inserted into or detached from the baffle.

[0008] Furthermore, the bottom of the detector body is provided with a threaded hole that communicates with the slide groove, and an operating rod is threadedly connected inside the threaded hole. One end of the operating rod extends into the slide groove and is rotatably connected to the base plate.

[0009] Furthermore, an elastic sealing gasket is fixedly provided on the top wall of the chute, surrounding the baffle.

[0010] Furthermore, the height of the operating rod is consistent with the height of the threaded hole.

[0011] Furthermore, the top wall of the chute is provided with a connection port for connecting to a pipe, and the connection port is provided through the baffle.

[0012] The beneficial effects of this utility model are as follows: This invention designs the reaction tank as a box that can slide out of the detector body, so as to facilitate manual cleaning of residual liquid on the inner wall of the reaction tank and ensure the accuracy of subsequent tests.

[0013] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the following drawings are provided for illustration: Figure 1 This is a perspective structural diagram of the detector body according to an embodiment of the present utility model; Figure 2 This is a side sectional view of the detector body according to an embodiment of the present invention.

[0015] The following components are marked in the attached diagram: detector body 1, slide 101, baffle 102, base plate 103, threaded hole 104, operating rod 105, elastic sealing gasket 106, connection port 107, sample pool 2, reagent pool 3, reaction pool 4. Detailed Implementation

[0016] like Figures 1-2As shown, this utility model provides a detection instrument for early lung cancer screening, comprising: an instrument body 1, wherein the instrument body 1 is an existing EVs automatic detection instrument for early lung cancer screening disclosed in CN220709039U, the specific structure and detection principle of which will not be described in detail here; the instrument body 1 is provided with a sample pool 2, a reagent pool 3, and a reaction pool 4 located between the sample pool 2 and the reagent pool 3; the reaction pool 4 is configured as a box; the instrument body 1 is provided with a slide 101 for accommodating the reaction pool 4; the slide 101 is connected to the outside of the instrument body 1; the reaction pool 4 can slide out of the instrument body 1 along the slide 101; the sample pool 2 and the reagent pool 3 are connected to the top wall of the slide 101 through pipes; the top wall of the slide 101 is provided with a connection port 107 for connecting to the pipes. Figure 1 and Figure 2 The diagram only shows the structural layout of sample cell 2, reagent cell 3 and reaction cell 4 in the main body 1 of the detector; the other structures are not shown. In this design, the vacuum pressure pump design in the existing technology (CN220709039U) is eliminated from the main body 1 of the detector. The remaining structure is consistent with the existing technology (CN220709039U), except that the reaction cell 4 is designed as a box with an opening at the top. The reaction cell 4 is slidably connected to the main body 1, allowing it to slide out of the detector body along the slide groove 101. This facilitates the cleaning of residual liquid on the inner wall of the reaction cell 4, ensuring the accuracy of subsequent tests. During testing, the liquid in the sample cell 2 and reagent cell 3 is pumped into the slide groove 101 via corresponding pumps and falls from the top wall of the slide groove 101 into the reaction cell 4 for reaction.

[0017] In one embodiment of the present invention, the height of the chute 101 is greater than the height of the reaction tank 4, a baffle 102 is fixedly provided on the top wall of the chute 101, the outer wall of the baffle 102 is in contact with the inner wall of the reaction tank 4, and a bottom plate 103 is slidably connected to the bottom wall of the chute 101. Sliding the bottom plate 103 can allow the reaction tank 4 to be inserted into or detached from the baffle 102.

[0018] In this scheme, before the reaction tank 4 slides into the chute 101, the bottom plate 103 is at its lowest position. At this time, the reaction tank 4 can slide into the chute 101. After the reaction tank 4 slides into the chute 101, the top wall of the reaction tank 4 is located below the bottom wall of the baffle 102. At this time, the bottom plate 103 is moved upward, thereby driving the reaction tank 4 to rise so that the baffle 102 can be inserted into the reaction tank 4. Then the bottom plate 103 is fixed so that the reaction tank 4 is fixed by the baffle 102. With the cooperation of the top wall of the chute 101 and the baffle 102, the internal space of the reaction tank 4 can be sealed to ensure the airtightness of the reaction tank 4.

[0019] In one embodiment of the present invention, the bottom of the detector body 1 is provided with a threaded hole 104 communicating with the slide groove 101, and an operating rod 105 is threadedly connected to the threaded hole 104. One end of the operating rod 105 extends into the slide groove 101 and is rotatably connected to the base plate 103.

[0020] In this solution, the base plate 103 is moved up and down within the slide groove 101 by rotating the operating lever 105. The operation is simple and ensures the stability of the base plate 103 after it moves to the preset position.

[0021] In one embodiment of the present invention, an elastic sealing gasket 106 is fixedly provided on the top wall of the slide groove 101 and is arranged around the baffle 102.

[0022] In this scheme, after the reaction tank 4 is moved upward so that the baffle 102 is inserted into the reaction tank 4, the top wall of the reaction tank 4 contacts the elastic sealing gasket 106 to improve the sealing of the reaction tank 4 and prevent the liquid in the reaction tank 4 from leaking out.

[0023] In one embodiment of this utility model, the height of the operating rod 105 is consistent with the height of the threaded hole 104. This ensures that when the base plate 103 is in contact with the bottom wall of the slide groove 101, the operating rod 105 does not extend below the detector body 1, thus guaranteeing the flatness of the bottom of the detector body 1 and facilitating its placement on a flat surface.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
