Claims

1. A blood collection tube sending module structure, comprising a module outer shell, a rotating wheel and a driving shaft structure, characterized in that: The module housing is designed with one or more upper and lower through-pipe ports and one or more specimen inlet ports. The rotating wheel is designed with through-pipe holes, bypass pipe holes, and bypass channels. The through-pipe holes pass straight through the center of the rotating wheel and out of the outer circumference of the rotating wheel through the center of the drive shaft structure. The bypass pipe holes are not on the same vertical line as the through-pipe holes in the rotating wheel. The bypass channels are connecting pipe holes for the upper and lower bypass pipe holes. The bypass pipe holes and through-pipe holes on the upper and lower outer circumferences of the rotating wheel are designed with independent sealing rings. The sending module is designed with a driver and a detection element.

2. The blood collection tube dispatching module structure according to claim 1, wherein, The upper and lower through-hole ports on the outer shell of the module have the same inner diameter as the through-hole in the rotating wheel and are designed on a vertical line. The specimen entry port is designed on a plane at an angle on the outer shell of the sending module and has the same diameter as the through-hole in the rotating wheel. The specimen entry port and the through-hole B section in the rotating wheel are on the same line.

3. The blood collection tube dispatching module structure of claim 1, wherein, When the rotating wheel is in a vertical position through the pipe hole, it can connect the upper and lower pipe ports of the sending module housing, and is isolated from the bypass pipe hole and the specimen entry port pipe hole. When the rotating body passes through the pipe hole to and from the upper pipe port and the specimen entry port of the sending module housing during specimen sending, it is always in an isolated state.

4. The blood collection tube dispatching module structure of claim 1, wherein, The upper and lower openings of the bypass pipe hole of the rotating wheel are elliptical. The bypass pipe hole and the bypass channel are not designed on the same vertical line. The bypass channel is designed on one side of the rotating wheel. The upper and lower bypass pipe holes are connected to form an air duct through the bypass channel.

5. The blood collection tube dispatching module structure of claim 1, wherein, The drive shaft structure has a non-through-center positioning shaft at the center of both ends of the rotating wheel. The positioning shaft has bearings on both sides, and the bearings are positioned on the module housing. The rotating body is equipped with a driver, which is a geared DC motor, fixed on the module housing.

6. The blood collection tube dispatching module structure of claim 1, wherein, The outer surface of the rotating wheel is designed with segmented sealing rings around the through-hole, bypass hole and the specimen inlet of the outer shell. Inner sealing rings are designed above and below the bypass hole, outer sealing rings are designed above and below the through-hole, and a cover sealing ring is designed at the bypass channel cover plate.

7. The blood collection tube dispatching module structure of claim 1, wherein, The rotating wheel rotates back and forth in only two positions within the module housing. The detection elements designed for these two positions are magnetic Hall elements, which are mounted on the module housing. The magnet is mounted on the rotating body. A detection element is designed at the specimen inlet port and the upper through-pipe port. The detection element is an infrared sensor.

8. The blood collection tube dispatching module structure of claim 1, wherein, The rotating wheel within the module housing only rotates back and forth between the specimen inlet port and the upper through-pipe port. As the rotating wheel rotates from the upper through-pipe port to the specimen inlet port through the pipe hole, the compressed air transporting the specimen will transfer from the through-pipe port to the bypass pipe hole without interruption. When the through-pipe port has completely reached the specimen inlet port, the compressed air will be transported entirely through the bypass pipe hole. When the rotating wheel moves back and forth between the specimen inlet port and the through-pipe port through the pipe hole, the compressed air will never enter the specimen inlet port.

9. The blood collection tube dispatching module structure of claim 1, wherein, The rotating wheels can be stacked in parallel and combined through the drive shaft structure to form multiple specimen entry tube ports, multiple upper passage tube ports, and multiple lower passage tube ports for sending modules.

10. The blood collection tube dispatching module structure of claim 9, wherein, The sending module composed of the rotating wheel multi-block parallel superposition can be used for sending to one target station or to multiple target stations, and the module driver only needs one, which can be installed on any side of the sending module according to the scene requirement.
