Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, specifically a flow cytometer sample shaking and anti-precipitation device. Background Technology

[0002] Flow cytometer is a device for automated analysis and sorting of cells, including counting various cells, detecting antigen molecules in cells, ploidy analysis of DNA and RNA in cells, and analysis of the biological characteristics and functions of cells. In hematological tests, samples analyzed by FCM are mostly peripheral blood, bone marrow, various body fluids (such as cerebrospinal fluid, pleural effusion, ascites), and human tissues (such as lymph nodes, spleen, liver, etc.). Before samples are tested by flow cytometer, they usually need to be shaken well. In the current technology, the collected samples are usually placed in sample tubes and the testers manually shake the samples in the sample tubes. Due to the large number of samples to be tested, shaking the samples is very inconvenient and the work is very labor-intensive. Utility Model Content

[0017] 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.

[0018] Example: Figure 1-4 As shown, this utility model provides a sample shaking and anti-precipitation device for flow cytometers, including a device frame 1. Mounting blocks 11 are fixedly installed at the bottom of both ends of the device frame 1. Several mounting holes 12 are provided on the mounting blocks 11. By using the mounting blocks 11 and mounting holes 12, the device frame 1 can be installed on a flow cytometer, or it can be used independently. Several placement tubes 2 are provided in the inner cavity of the device frame 1. Sample tubes can be placed inside the placement tubes 2 for subsequent shaking operations. Two clamping plates 21 are provided inside the placement tubes 2. Two Z-shaped elastic elements 22 are fixedly installed on the inner wall of the placement tubes 2. One side of the Z-shaped elastic element 22 and... One side of the clamping plate 21 is fixedly connected. By setting the Z-shaped elastic element 22 and the clamping plate 21, when the sample tube is inserted into the interior of the placement tube 2, the bottom of the sample tube causes the two clamping plates 21 to move away from each other (the upper ends of the two clamping plates 21 are tilted outward). The clamping plate 21 causes the Z-shaped elastic element 22 to contract. The Z-shaped elastic element 22 clamps the sample tube by its own extension characteristics and with the cooperation of the clamping plate 21, thereby improving the stability of the sample tube. A shaking component 3 is provided between the equipment frame 1 and the placement tube 2. By setting the shaking component 3, the shaking component 3 can make multiple placement tubes 2 swing back and forth, thereby realizing the shaking operation of multiple sample tubes. The shaking assembly 3 includes a frame plate 31, and several placement tubes 2 are detachably installed on one side of the frame plate 31. Both ends of the frame plate 31 are fixedly provided with rotating shafts 32, which are rotatably connected to one end of the equipment frame 1. One end of each of the two rotating shafts 32 is fixedly provided with a driven gear 33. By driving the driven gear 33 to rotate back and forth, the driven gear 33 can make the rotating shaft 32 rotate back and forth. The rotating shaft 32 can make the multiple placement tubes 2 swing back and forth about the axis of the rotating shaft 32 through the frame plate 31. A drive motor 34 is fixedly mounted on the upper surface of the equipment frame 1. A rotating rod 35 is fixedly mounted on the drive output end of the drive motor 34. A first bevel gear 36 is fixedly mounted on one end of the rotating rod 35. Two transmission rods 37 are rotatably mounted on the top wall of the equipment frame 1. A second bevel gear 38 is fixedly mounted on one end of each of the two transmission rods 37. The two second bevel gears 38 are mirror images of each other. The first bevel gear 36 meshes with the two second bevel gears 38. An incomplete gear 39 is fixedly mounted on the other end of each of the two transmission rods 37. One of the incomplete gears 39 is connected to a... The driven gear 33 is vertically aligned. By starting the drive motor 34, the drive shaft of the drive motor 34 can rotate the first bevel gear 36 through the rotating rod 35. The first bevel gear 36 can cause the two transmission rods 37 to rotate synchronously in opposite directions through the two mirrored second bevel gears 38. The two transmission rods 37 can cause the two incomplete gears 39 to rotate synchronously in opposite directions. When one incomplete gear 39 meshes with one driven gear 33, the other incomplete gear 39 is disengaged from the other driven gear 33, thereby enabling the two driven gears 33 to rotate synchronously in opposite directions.

[0019] An installation assembly 4 is provided between the placement tube 2 and the frame plate 31. The installation assembly 4 includes several insertion rods 41, one of which is fixedly mounted on the outer wall of a placement tube 2. The frame plate 31 has several insertion holes 42. One end of the insertion rod 41 is interference-fitted with the inner wall of the insertion hole 42. By setting the insertion rod 41 and the insertion hole 42, when the insertion rod 41 is horizontally inserted into the insertion hole 42, the placement tube 2 can be assembled on one side of the frame plate 31. The reverse operation can be performed to assemble the placement tube 2 onto the frame plate 31. The frame plate 31 is separated to disassemble the placement tube 2. Several locking screws 43 are rotatably installed on the lower end face of the frame plate 31. One end of the insertion rod 41 is provided with a threaded hole 44. One end of the locking screw 43 is rotatably connected to the inner wall of the threaded hole 44. The other end of the locking screw 43 is fixedly provided with a hexagonal rotating disk 45. By rotating the hexagonal rotating disk 45, the locking screw 43 can be rotated. When the locking screw 43 is threaded into the inside of the threaded hole 44, the insertion rod 41 can be fixed on the frame plate 31.

[0020] Working principle: When it is necessary to shake the sample to be tested, the tester first vertically inserts multiple sample tubes containing the sample into multiple placement tubes 2. During the insertion process, the bottom end of the placement tube 2 contacts the two clamping plates 21 and pushes the two clamping plates 21 away from each other. The two clamping plates 21 cause the two Z-shaped elastic elements 22 to contract and deform. The two Z-shaped elastic elements 22 clamp the sample tubes with their own extension characteristics and with the cooperation of the two clamping plates 21, thereby improving the stability of the sample tubes. Subsequently, the testing personnel start the drive motor 34. The drive shaft of the drive motor 34 causes the first bevel gear 36 to rotate through the rotating rod 35. The first bevel gear 36 causes the two transmission rods 37 to rotate synchronously in opposite directions through two mirrored second bevel gears 38. The two transmission rods 37 cause the two incomplete gears 39 to rotate synchronously in opposite directions. The intermittent engagement between the two incomplete gears 39 and the two passive gears 33 causes the two passive gears 33 to rotate in the forward direction and then in the reverse direction. The two passive gears 33 cause the frame plate 31 to swing back and forth through the two rotating shafts 32. The multiple placement tubes 2 and multiple sample tubes mounted on one side of the frame plate 31 swing back and forth synchronously, shaking the samples in the multiple sample tubes evenly. This facilitates the shaking operation of multiple sample tubes, thereby effectively improving the convenience of the sample shaking operation and reducing the workload of the testing personnel. Meanwhile, by setting a plug rod 41, a plug hole 42, a locking screw 43, a threaded hole 44 and a hexagonal rotating disk 45 between the placement tube 2 and the frame plate 31, the placement tube 2 can be assembled on one side of the frame plate 31, and the placement tube 2 can also be disassembled separately to facilitate the inspection personnel to clean and disinfect the placement tube 2.
