Description

Technical Field

[0001] This utility model relates to the technical field of biological sample screening, and in particular to a pulmonary hypertension screening and detection cavity structure resistant to electromagnetic interference. Background Technology

[0002] Biosample screening is a technical process that uses biomedical technology to detect and analyze samples (such as blood, urine, tissue, cells, etc.) from the human body or other organisms in order to extract key information related to health status, disease risk, and physiological characteristics. The screening work requires the use of biosample screening equipment.

[0003] To address the aforementioned issues, a search revealed a patent with publication number CN113406342B that discloses a blood-based pan-cancer screening device. The document states that "cancer refers to malignant tumors originating from epithelial tissue and is the most common type of malignant tumor. Early detection and diagnosis of cancer through screening devices can effectively reduce mortality rates; therefore, screening is crucial." According to patent application number CN201711170283.4, which provides a pan-cancer early screening kit based on plasma exosome GRP78 mRNA, this product is an early cancer screening kit based on GRP78 mRNA in plasma exosomes. It contains a pair of exosome GRP78 mRNA fluorescent quantitative PCR primers, the nucleotide sequences of which are shown in SEQ ID NO: 1~2. This product can complete early screening for multiple cancers using only 5 ml of blood, making the early cancer detection method specific, sensitive, efficient, practical, non-invasive, and highly reliable. It is easy to promote clinically in medical institutions at all levels and is particularly suitable for cancer-prone patients. This invention is of great significance for physical examination screening and early warning. Compared with existing technologies, the beneficial effects of this invention are as follows: First, this invention can automatically move blood tubes to the bottom of the screening device and create a sealed environment for the screening device to operate, thereby improving screening efficiency. Specifically, the test tube is taken out by the finger-gripping cylinder in the test tube picking and placing mechanism, and then moved to the bottom of the screening device by the sliding block on the screw at the bottom of the finger-gripping cylinder. This reduces repetitive labor caused by manual operation. Since the dynamic sealing box is fixed on the sliding block, a sealed environment is formed by the dynamic sealing box and the static sealing box fixed on the worktable for the screening device to detect, preventing external impurities from contaminating the blood. Second, this invention can increase the pressure in the crushing chamber and decrease the pressure in the storage chamber, thereby improving the sterilization effect of the crushing chamber by using a high temperature and high pressure environment and improving the low temperature and low pressure environment of the storage chamber, thus improving the preservation effect of the test tubes. However, existing screening devices have poor anti-interference ability against electromagnetic signals. In an electromagnetic interference environment, the signal is easily distorted, and the accuracy of the detection results is low.

[0004] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-5 The present invention provides a technical solution: a pulmonary hypertension screening and detection cavity structure with electromagnetic interference resistance, including an anti-interference shell 1; One end of the anti-interference shell 1 is provided with a fixing mechanism 2, and the other end of the fixing mechanism 2 is provided with an adjustment mechanism 3; The fixing mechanism 2 includes a base 201, a support frame 202 mounted on one side surface of the base 201, a placement hole 203 formed on one side surface of the support frame 202, a base plate 204 mounted on one side surface of the base 201, a double-acting screw 205 mounted on one end of the base plate 204, a ball bearing nut seat 206 sleeved on the outer wall of the double-acting screw 205, a connecting block 207 mounted on the outer wall of the ball bearing nut seat 206, a connecting plate 208 mounted on one side surface of the connecting block 207, and a fixing plate 209 mounted on one side surface of the connecting plate 208. Through the arrangement of the anti-interference housing 1, base 201, support frame 202, placement hole 203, base plate 204, double-acting screw 205, ball bearing nut seat 206, connecting block 207, connecting plate 208, and fixing plate 209, the anti-interference housing 1 has an internal opening... The cavity contains titanium alloy plates, permalloy plates, and resin-based carbon fiber composite plates arranged from the inside out. This structure significantly improves the electromagnetic interference resistance of the anti-interference shell 1 and enhances the accuracy of the test results. When placing the sample tube, the sample tube is placed into the placement hole 203, and then the bidirectional screw 205 is rotated. At this time, the two ball nut seats 206 will move towards the sample tube simultaneously through the connecting block 207, along with the two connecting plates 208. The two fixing plates 209 will then fix the sample tube, resulting in better stability of the sample tube during testing. Furthermore, the anti-interference shell 1 is equipped with a filter circuit inside. As an "anti-interference defense line," the filter circuit can filter out power supply noise, high-frequency electromagnetic radiation, and signal crosstalk, ensuring the stability and accuracy of the screening work and avoiding detection errors caused by signal distortion.

[0018] Furthermore, the bidirectional screw 205 is installed inside the base plate 204 via bearings. The bidirectional screw 205 and the base plate 204 form a rotating structure. With the bidirectional screw 205 in place, when the bidirectional screw 205 rotates, the ball nut seat 206 can carry the connecting plate 208 in a linear motion.

[0019] Furthermore, the placement holes 203 are equally spaced on the surface of the support frame 202. Two sets of ball nut seats 206 and connecting blocks 207 are provided. Through the arrangement of ball nut seats 206 and connecting blocks 207, ball nut seats 206 can move linearly with connecting plates 208 via connecting blocks 207. The fixing plate 209 on one side of the connecting plate 208 will also move linearly. The fixing plate 209 can clamp and fix the sample tube, improving the stability of screening.

[0020] Furthermore, a limiting block 210 is installed on one side surface of the connecting block 207, and a limiting groove 211 is opened on one side inner wall of the base plate 204. With the setting of the limiting block 210 and the limiting groove 211, the limiting block 210 will slide in the limiting groove 211 when the connecting block 207 moves. The limiting block 210 can assist and limit the movement of the connecting block 207.

[0021] Furthermore, the adjustment mechanism 3 includes a gear 301, a support base 302 mounted on one side surface of the base plate 204, a connecting groove 303 formed on one side surface of the support base 302, a sliding groove 304 formed on one side surface of the support base 302, a slider 305 disposed inside the sliding groove 304, a rack 306 mounted on one side surface of the slider 305, and an auxiliary plate 307 mounted on one side surface of the slider 305. Through the arrangement of the gear 301, support base 302, connecting groove 303, sliding groove 304, slider 305, rack 306, and auxiliary plate 307, when the bidirectional screw 205 needs to be rotated, the auxiliary plate 307 is moved. The auxiliary plate 307 allows the slider 305 to slide in the sliding groove 304, and the slider 305 can move the rack 306. When the rack 306 moves, the gear 301 meshing with it will be rotated. The gear 301 can rotate the bidirectional screw 205, thereby adjusting the position of the fixed plate 209.

[0022] Furthermore, the slider 305 forms a sliding structure with the support base 302 through the slide groove 304, and the gear 301 and the rack 306 are meshed. With the setting of the slide groove 304 and the slider 305, the slider 305 can move linearly with the rack 306 when sliding in the slide groove 304, and the position of the fixed plate 209 can be adjusted.

[0023] Furthermore, a connecting shell 308 is installed on one side surface of the auxiliary plate 307, and a spring 309 is installed inside the connecting shell 308. One end of the spring 309 is connected to a moving block 310, and a limit rod 311 is installed on one end of the moving block 310. A limit hole 312 is opened on one side surface of the support base 302. With the setting of the connecting shell 308, spring 309, moving block 310, limit rod 311 and limit hole 312, when the auxiliary plate 307 needs to be moved, the limit rod 311 is pulled. When the limit rod 311 leaves the limit hole 312, the auxiliary plate 307 can move with the slider 305. When the slider 305 moves to the appropriate position, the limit rod 311 is released. At this time, under the action of the spring 309, the moving block 310 will take the limit rod 311 and lock into the limit hole 312 at the corresponding position, thus completing the fixation of the position of the auxiliary plate 307 and the slider 305.

[0024] Working Principle: The anti-interference housing 1 has an internal cavity containing, from the inside out, a titanium alloy plate, a permalloy plate, and a resin-based carbon fiber composite plate. This structure significantly improves the anti-interference housing 1's resistance to electromagnetic interference and enhances the accuracy of the test results. When placing the sample tube, the sample tube is placed into the placement hole 203, and then the bidirectional screw 205 is rotated. At this time, the two ball bearing nut seats 206 move towards the sample tube simultaneously through the connecting block 207, along with the two connecting plates 208. The two fixing plates 209 then fix the sample tube, resulting in better stability of the sample tube during testing. Furthermore, the anti-interference housing 1 has an internal filtering circuit. This filtering circuit acts as an "anti-interference defense line," filtering out power supply noise, high-frequency electromagnetic radiation, and signal crosstalk, ensuring the stability and accuracy of the screening work and preventing signal distortion. To detect errors, the auxiliary plate 307 needs to be moved when the bidirectional screw 205 is rotated. The auxiliary plate 307 allows the slider 305 to slide in the groove 304, which in turn moves the rack 306. When the rack 306 moves, the gear 301 meshing with it is rotated, which in turn rotates the bidirectional screw 205, thereby adjusting the position of the fixed plate 209. When the auxiliary plate 307 needs to be moved, the limiting rod 311 is pulled. When the limiting rod 311 leaves the limiting hole 312, the auxiliary plate 307 can move the slider 305. When the slider 305 moves to the appropriate position, the limiting rod 311 is released. At this time, under the action of the spring 309, the moving block 310 will move the limiting rod 311 into the corresponding limiting hole 312, thus fixing the position of the auxiliary plate 307 and the slider 305.
