Description

Technical Field

[0001] This utility model relates to the field of concentration instruments, specifically an exosome extraction and concentration instrument. Background Technology

[0002] A concentrator is an instrument used in scientific research experiments, environmental monitoring and evaluation experiments, analytical testing experiments, and material composition analysis research. It is typically used to extract exosomes from bodily fluids such as urine, pleural and peritoneal effusions, breast milk, and saliva.

[0003] Currently, most concentrators are centrifugal concentrators. In use, test tubes containing liquid are mounted on a support frame inside the concentrator, and then the liquid is centrifuged at high speed to extract exosomes. Since the concentration of the extracted liquid varies and the centrifugal force required for centrifugation differs, the test tubes need to be adjusted to different angles; otherwise, the extraction efficiency will be reduced. However, the support frame inside existing concentrators is generally fixed to the motor drive shaft inside the concentrator, so the angle cannot be adjusted during use. Different support frames are required to extract exosomes from different bodily fluids, which is cumbersome and reduces the flexibility of the concentrator. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an exosome extraction and concentration instrument that solves the problem of inconvenient adjustment of the fixed support frame inside traditional concentrators. This allows for flexible adjustment of the support frame angle when extracting exosomes from different liquids, thus reducing the inconvenience for operators and improving the flexibility of the concentrator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an exosome extraction and concentration instrument, comprising a concentration instrument body, an extraction chamber inside the concentration instrument body, and an extraction tank inside the extraction chamber. Multiple sets of supports are fixedly installed on the inner wall of the extraction tank, and a collar is rotatably connected to the inner surface of each support. A tank cover is fixedly connected to one end of the collar, and a rotating seat is hinged to the upper end of a support plate. An adjusting screw is rotatably connected to the upper surface of the rotating seat. Multiple sets of sliding grooves are formed on the upper surface of the extraction tank, and a moving block is slidably connected inside each groove. The upper end of the adjusting screw passes through the moving block and is threadedly connected to it. A cover plate is installed on the upper surface of one end of the concentration instrument body, and a controller is installed on one side of the cover plate.

[0006] Preferably, a marker is fixedly connected to the upper surface of the movable block, and a marking line is provided on one side of the slide groove, with the marking line corresponding to the marker.

[0007] Preferably, the upper end of the extraction tank is equipped with a tank cover, and a limit ring is fixedly connected to the upper surface of the tank cover.

[0008] Preferably, a sealing ring is fixedly connected to the inner surface of the cover plate, and a limit rod is slidably connected inside the cover plate. One end of the limit rod is fixedly connected to a spring, and one end of the spring is fixedly connected to the outer surface of the cover plate.

[0009] Preferably, a drive shaft is fixedly connected to the lower surface of the extraction tank, and a drive motor is fixedly connected to the lower end of the drive shaft.

[0010] Preferably, the inner wall of the extraction chamber is fixedly connected to a, and the upper end of the chamber is fixedly connected to a, wherein a wear-resistant ring is provided above, and the wear-resistant ring is fixedly connected to the lower surface of the extraction tank.

[0011] Preferably, the inner surface of the slide groove is symmetrically provided with limiting slide grooves, and the interior of the limiting slide groove is fixedly connected to the moving block by a limiting slider.

[0012] Preferably, the cover plate has symmetrical grooves on one side surface, and a slider is slidably disposed inside the groove, and one side surface of the slider is fixedly connected to the side surface of the limiting rod.

This solves the problem of inconvenient adjustment of the fixed installation of the internal support frame of the traditional concentrator. As a result, the angle of the support frame can be flexibly adjusted when extracting exosomes from different liquids, thus reducing the trouble for the staff and improving the flexibility of the concentrator.

[0015] 2. The limiting ring on the upper surface of the extraction tank cover and the limiting rod that is slidably connected inside the cover plate cooperate with the spring that is fixedly connected to one end of the limiting rod.
