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

[0002] Radioimmunoassay (RIA) is a labeled immunoassay technique developed by Yalow and Berson in 1960. Due to the high sensitivity and accuracy of the labeled radionuclides, it is widely used in the medical field. During RIA, it is usually necessary to count the number of test tubes.

[0003] Existing radioimmunoassay counters typically require manual placement of test tubes into the detection tubes for radioimmunoassay counting. However, when there are many test tubes, manual loading and unloading can be labor-intensive and reduce efficiency. Therefore, we propose a new radioimmunoassay counter. Utility Model Content

[0041] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0042] Example:

[0043] like Figures 1-5 As shown, a radioimmunoassay counter includes:

[0044] Mounting base 1, with symmetrical support blocks at its bottom end;

[0045] The first conveyor belt 2 and the second conveyor belt 3 are symmetrically arranged inside the top of the mounting base 1, and are driven by a motor and a drive roller in opposite directions.

[0046] The test tube rack 4 is connected and is movably placed on top of the mounting base 1. Grooves are provided on both its front and rear surfaces.

[0047] The test tube body 5 is movably placed inside the test tube rack 4, and grooves are provided on the outer side of its top surface.

[0048] The fixed mounting base 6 is fixedly located at the top center of the mounting base 1, and has a radioimmunoassay counting component inside.

[0049] The detection socket 7 is fixedly opened on the top of the fixed mounting base 6;

[0050] The fixed limiting frame 10 is fixedly installed on the top edge of the mounting base 1, and a through groove is provided on its rear surface.

[0051] The transverse conveying mechanism 8 is bolted to the rear surface of the fixed limiting frame 10;

[0052] The clamping and moving mechanism 9 is bolted to the top of the transverse conveying mechanism 8.

[0053] The working principle of the above technical solution is as follows:

[0054] During use, the connecting test tube rack 4 and connecting test tube body 5 are conveyed by the first conveyor belt 2, and then conveyed by the transverse conveying mechanism 8, so that the connecting test tube rack 4 and connecting test tube body 5 can move to the inside of the output end of the clamping and moving mechanism 9. Then, under the action of the clamping and moving mechanism 9, the connecting test tube body 5 can be taken out from the inside of the connecting test tube rack 4, and then the connecting test tube body 5 is inserted into the inside of the detection socket 7, so as to perform radioimmunoassay on the sample inside the connecting test tube body 5. Then, the connecting test tube body 5 is removed from the inside of the connecting test tube rack 4. The inner side of the detection socket 7 is removed, and the connecting test tube body 5 is reinserted into the inner side of the connecting test tube rack 4. Then, the transverse conveying mechanism 8 transports the connecting test tube rack 4 and the connecting test tube body 5 to the top of the second conveyor belt 3. The second conveyor belt 3 can transport the connecting test tube rack 4 and the connecting test tube body 5. The overall structure is simple and the operation is convenient and quick. The radioimmunoassay counting component inside the fixed mounting base 6 usually uses a photoelectric sensor to achieve precise sample positioning and automatic control. In the detection system of the radioimmunoassay counter, the photomultiplier tube is one of the core components. It can convert the light signal emitted by the scintillator into an electrical signal and amplify it. After the scintillator interacts with gamma rays, it produces photons. These photons are transmitted to the photocathode of the photomultiplier tube through an optical coupler and a light guide. The photomultiplier tube converts the light signal into an electrical signal, thereby realizing the detection of radioactive signals. This is existing technology, so it will not be described in detail.

[0055] In another embodiment, such as Figure 3 As shown, the transverse conveying mechanism 8 includes a first support leg 81, one end of which is fixedly connected to a first connecting mounting bracket 82. The first connecting mounting bracket 82 has a fixed inner groove 83 inside. One bottom end of the first connecting mounting bracket 82 is fixedly connected to a servo motor 84. The output end of the servo motor 84 is fixedly connected to a sprocket. The inner side of the first connecting mounting bracket 82 away from the servo motor 84 is movably connected to a sprocket. The outer surface of the sprocket is movably connected to a connecting transmission chain 85. The outer surface of the connecting transmission chain 85 is fixedly provided with a second connecting mounting bracket 86. One side of the second connecting mounting bracket 86 is fixedly connected to a connecting transmission rod 87.

[0056] This allows the servo motor 84 to drive the sprocket, which in turn moves the connecting transmission chain 85. This enables the end of the connecting transmission rod 87 to engage with the groove on the outer side of the connecting test tube rack 4, thus moving the connecting test tube rack 4 and the connecting test tube body 5 laterally. This makes the operation convenient and quick.

[0057] In another embodiment, such as Figure 3 As shown, threaded mounting holes 88 are symmetrically provided on the top of the first connecting mounting bracket 82.

[0058] It is easy to connect and fix with the clamping and moving mechanism 9 by bolts, and is convenient to operate.

[0059] In another embodiment, such as Figure 4 As shown, the clamping and moving mechanism 9 includes a second leg 91. One end of the second leg 91 is fixedly connected to a third connecting mounting bracket 92. The top of the third connecting mounting bracket 92 is fixedly connected to a first electric telescopic rod 93. The output end of the first electric telescopic rod 93 is fixedly connected to a connecting mounting base block 94. A fixed connecting frame 95 is fixedly connected to one side of the connecting mounting base block 94. The inner side of the fixed connecting frame 95, away from the first electric telescopic rod 93, is bolted to a connecting mounting plate 96. A second electric telescopic rod 97 is fixedly connected to one side of the connecting mounting plate 96. The output end of the second electric telescopic rod 97 is fixedly connected to a connecting end plate 98. A movable mounting block 99 is movably sleeved on the outer surface of the connecting end plate 98. A movable base block 910 is fixedly connected to the bottom end of the movable mounting block 99. A connecting clamping block 911 is fixedly connected to the bottom end of the movable base block 910. The outer side of the bottom end of the connecting clamping block 911 fits against the inner side of the groove on the outer side of the top surface of the connecting test tube body 5. Fixed guide grooves 912 are symmetrically opened on the inner side of the fixed connecting frame 95. Both ends of the movable base block 910 are provided with connecting guide protrusions 913.

[0060] To facilitate the movement of the outer top of the test tube body 5 to the inner side of the connecting clamping block 911, the first electric telescopic rod 93 drives the connecting mounting base block 94 and the fixed connecting frame 95 to move, thereby driving the connecting mounting plate 96, the second electric telescopic rod 97, the connecting end plate 98, the movable mounting sleeve block 99, the movable base block 910, and the connecting clamping block 911 to move, thus moving the test tube body 5. At the same time, the second electric telescopic rod 97 retracts, driving the connecting end plate 98, the movable mounting sleeve block 99, the movable base block 910, the connecting clamping block 911, and the test tube body 5 to move. The first electric telescopic rod 93 then drives the connecting mounting base block 94 to reset, allowing the test tube body 5 to be inserted into the inner side of the detection socket 7, pressing the pressure sensor. The number of times the pressure sensor is subjected to pressure is counted, making the operation convenient and quick.

[0061] In another embodiment, such as Figure 4 As shown, the outer surface of the connecting guide protrusion 913 is in contact with the inner surface of the fixing guide groove 912.

[0062] When the movable base block 910 is moved, it can drive the connecting guide protrusion 913 to move stably inside the fixed guide groove 912, making operation convenient.

[0063] In another embodiment, such as Figure 4 As shown, a fixing sleeve 914 is fixedly sleeved on the outer side of the end surface of the second electric telescopic rod 97. Both ends of the fixing sleeve 914 are provided with protrusions, which fit together with the top of the fixing connection frame 95. A connecting handle 915 is fixedly connected to the middle of the top of the fixing sleeve 914.

[0064] The fixing block 914 can restrict and fix the end of the second electric telescopic rod 97, so that the second electric telescopic rod 97 can be in a stable working state and is easy to operate.

[0065] In another embodiment, such as Figure 4 As shown, fixed guide limit blocks 916 are symmetrically provided on both sides of the third connecting mounting bracket 92. A connecting guide block 918 is movably connected to the inner side of the fixed guide limit block 916. A fixed connecting plate 917 is fixedly connected to one end of the connecting guide block 918. One end of the fixed connecting plate 917 is fixedly connected to one end of the fixed connecting frame 95.

[0066] When the fixed connecting frame 95 moves, it can drive the fixed connecting plate 917 and the connecting guide block 918 to move, so that the connecting guide block 918 can move inside the fixed guide limit block 916, guiding and restricting the fixed connecting frame 95, thereby preventing the end of the fixed connecting frame 95 from tilting downwards, and making operation convenient.

[0067] The working principle of this utility model is as follows: During use, the connecting test tube rack 4 and the connecting test tube body 5 are first placed on top of the first conveyor belt 2. The first conveyor belt 2 transports the connecting test tube rack 4 and the connecting test tube body 5, causing them to move to one end of the inner side of the fixed limiting frame 10. Then, the servo motor 84 drives the sprocket, causing the connecting transmission chain 85 to move, so that the end of the connecting transmission rod 87 can be engaged in the groove on the outer side of the surface of the connecting test tube rack 4, causing the connecting test tube rack 4 and the connecting test tube body 5 to move laterally. The outer top of the connecting test tube body 5 moves to the inner side of the connecting clamping block 911. At this time, the first electric telescopic rod 93 drives the connecting mounting base block 94 and the fixed connecting frame 95 to move, thereby driving the connecting mounting plate 96, the second electric telescopic rod 97, the connecting end plate 98, the movable mounting sleeve block 99, the movable base block 910, and the connecting clamping block 911 to move, thus moving the connecting test tube body... The body 5 moves while the second electric telescopic rod 97 retracts, driving the connecting end plate 98, movable mounting sleeve 99, moving base block 910, connecting clamping block 911, and connecting test tube body 5 to move. The first electric telescopic rod 93 drives the connecting mounting base block 94 to reset, allowing the connecting test tube body 5 to be inserted into the inside of the detection socket 7. Radioimmunoassay is performed on the sample inside the connecting test tube body 5. After the counting is completed, the first electric telescopic rod 93 and the second electric telescopic rod 97 reset, allowing the connecting test tube body 5 to be inserted into the inside of the connecting test tube rack 4. Then, the transverse conveying mechanism 8 moves the connecting test tube rack 4 and the connecting test tube body 5 laterally to the top of the second conveyor belt 3. The second conveyor belt 3 then transports the connecting test tube rack 4 and the connecting test tube body 5. The overall structure is simple and the operation is convenient and quick. It does not require manual insertion of the connecting test tube body 5 into the detection socket 7, improving efficiency while reducing the labor intensity of manual operation.

[0068] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
