[0018] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] To ensure the flatness of the PCR tube capping, as Figures 1-4As shown in the figure, a combined PCR octuplet tube of the present utility model includes a PCR tube 1, an exhaust cover 2 and a three-leg connector 3. There are eight groups of the PCR tubes 1, and the mouths of the eight groups of the PCR tubes 1 are connected by the three-leg connector 3. The exhaust cover 2 is covered on the top of the PCR tube 1.
[0020] During use, the PCR tube 1, the exhaust cover 2 and the three-leg connector 3 provide a set of PCR octuplet tubes with good use stability for medical detection and screening, which can ensure the stability of the lid of the PCR tube 1. When the lid seals the PCR tube 1, it can ensure the sealing effect of the lid and the flatness of the lid.
[0021] The present utility model further includes that the exhaust cover 2 includes a pressing cover 21, a protrusion 22, an exhaust groove 23 and an exhaust port 24. The side of the protrusion 22 away from the PCR tube 1 is arranged at the center of the pressing cover 21. The exhaust groove 23 is opened on the top of the pressing cover 21 on the side away from the protrusion 22. The exhaust port 24 is arranged at the center of the exhaust groove 23 and penetrates through the bottom of the pressing cover 21.
[0022] The present utility model further includes that a silica gel sheet 27 is arranged in the exhaust port 24. At the center of the silica gel sheet 27, there are three groups of blades 28 integrated with it. The tops of the three groups of blades 28 are all connected with a top block 29.
[0023] During use, by pressing the protrusion 22, the bottom of the exhaust cover 2 is embedded into the mouth of the PCR tube 1. The excess air at the bottom of the exhaust cover 2 is pressed and will push the blades 28 of the silica gel sheet 27, causing the blades 28 to open. And the top block 29 at the top of the blades 28 pushes the silica gel baffle 25, so that the excess air flow in the tube will pass through the blades 28 and the top block 29 and be discharged outwards from the outer periphery of the silica gel baffle 25.
[0024] The present utility model further includes that a silica gel baffle 25 coaxial with the silica gel sheet 27 is arranged in the exhaust groove 23. A connecting belt 26 integrated with it is arranged on the outer periphery of the silica gel baffle 25.
[0025] The side of the connecting belt 26 away from the silica gel baffle 25 is connected with the exhaust groove 23.
[0026] During use, based on the characteristic of the silica gel shrinkage force of the blades 28, the blades 28 drop back under the loss of pressure. At the same time, the silica gel baffle 25 drops back and presses against the top block 29, further improving the closing effect of the blades 28 dropping back.
[0027] When the utility model is in use, the agent liquid to be detected and processed is injected into the PCR tube 1, and the top of the PCR tube 1 is covered and protected by the exhaust cover 2. When covering, the operator presses the protrusion 22, so that the bottom of the exhaust cover 2 is embedded into the tube orifice of the PCR tube 1. When the exhaust cover 2 is covered, the redundant air at the bottom of the exhaust cover 2 will press and push the blade 28 of the silica gel sheet 27, so that the blade 28 is opened, and the top block 29 at the top of the blade 28 pushes the silica gel baffle 25, so that the redundant air flow in the tube will pass through the blade 28 and the top block 29 and is discharged outwards from the periphery of the silica gel baffle 25;
[0028] After the exhaust is completed, based on the characteristic of the silica gel shrinkage force, the blade 28 loses pressure and drops back, and at the same time the silica gel baffle 25 drops back and presses and fits on the top block 29, so as to further improve the closing effect of the blade 28 dropping back.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the utility model.
