Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of test tube shaking, in particular to a manual test tube shaker. Background Art
[0002] In the red blood cell centrifugation test, it is often necessary to manually shake the test tube to observe and compare the aggregation of the cell buckles after centrifugation and the discrete state during the shaking process. Each test tube generally contains only 150 microliters of liquid plus red blood cells. Centrifuge first, and the cells will form clumps and adhere to the bottom of the tube. Tilt the bottom of the test tube back and forth gently, allowing the supernatant to slowly wash the cell buckles back and forth, and observe the cell buckles falling off the bottom of the tube. Then gently shake the test tube again to observe the discrete state of the cell buckles that fall off as the shaking progresses.
[0003] Generally, multiple test tubes need to be shaken and observed at the same time, but there are two disadvantages to shaking multiple test tubes. First, the number is limited. Holding 4-6 test tubes at the same time is basically the limit, but the experimenter often needs to observe more than 12 test tubes, so it is often necessary to shake more than three times, and there will be differences in the amplitude of the shaking force and subjective judgment each time. Second, the amplitude of the test tubes will be inconsistent when holding them. When holding a row of test tubes, there will be differences between the leftmost and rightmost. Especially when the agglutination is relatively weak, this difference may lead to artificial errors in the results. Utility Model Content
[0004] In order to solve the deficiencies in the prior art, the utility model provides a manual test tube shaker, which arranges test tube clamps side by side on a test tube rack, fixes the test tubes by the test tube clamps, and can fix multiple test tubes at one time, thereby ensuring the consistency of shaking. At the same time, when the test tube rack is shaken by a turntable, the amplitudes of all the parallel test tubes are consistent, further ensuring the consistency of shaking and reducing human errors.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The utility model provides a manual test tube shaker, comprising a frame, a test tube rack is arranged on the frame, and a plurality of test tube clamps are arranged side by side on the test tube rack;
[0007] The test tube clamp comprises a column, the column is fixed on the test tube rack, a clamping piece is respectively arranged on both sides of the column, the middle parts of the two clamping pieces are rotatably connected through the column, a wing edge is arranged on the same side of the two clamping pieces, a clamping arm is arranged on the other side opposite to the two clamping pieces, and a torsion spring is arranged between the two wing edges;
[0008] Both ends of the test tube rack are rotatably connected to the frame respectively, and one end of the test tube rack extends out of the frame and is connected to a turntable.
[0009] The utility model provides a manual test tube shaker, during operation, the test tubes containing red blood cell solution are fixed in sequence by the test tube clamps. Since the test tube clamps themselves are arranged side by side, the consistency in position of the test tubes is ensured. The test tubes are clamped by the clamping force applied by the torsion springs. When the test tubes are highly stable, shaking can begin. The test tubes can be shaken by rotating the turntable during shaking. The amplitudes of the test tubes with high stability and consistent positions are kept consistent. The amplitude and speed can be manually controlled during shaking to meet different requirements of flushing cell buckles and observing discreteness.
[0010] The manual test tube shaker of the utility model arranges test tube clamps side by side on the test tube rack, and fixes the test tubes through the test tube clamps, so that multiple test tubes can be fixed at one time, thereby ensuring the consistency of shaking; at the same time, when the test tube rack is shaken by a turntable, the amplitudes of all the parallel test tubes are consistent, thereby further ensuring the consistency of shaking and reducing human errors.
[0011] In a further technical solution, jackets are detachably provided on opposite sides of the two clamping arms.
[0012] The setting of the jacket allows jackets of different sizes to be selected for installation according to the model of the test tube to be clamped, so that the clamping space matches the size of the test tube, ensuring the stability of the clamp arm in clamping the test tube.
[0013] In a further technical solution, anti-slip grooves are arranged on the opposite surfaces of the jacket.
[0014] The setting of the anti-slip pattern further improves the stability of the relative position between the test tube and the test tube clamp.
[0015] In a further technical solution, a scale is provided on the column.
[0016] The setting of the scale helps to determine the height of the test tube when it is clamped, so that all the test tubes are at the same height, further ensuring the consistency of all the test tubes when shaking.
[0017] In a further technical solution, a rotating handle is provided on the rotating disk.
[0018] The turntable is controlled by the handle, which is more convenient to operate.
[0019] In a further technical solution, the rotating handle includes a first rotating handle and a second rotating handle, and the distance between the first rotating handle and the center of the rotating disk is greater than the distance between the second rotating handle and the center of the rotating disk.
[0020] Since the operations of flushing the cell button and observing the discreteness are different, the operation is further facilitated by setting two rotating handles with different distances between the two rotating handles and the center of the circle.
[0021] In a further technical solution, a ring is sleeved on the rotating handle.
[0022] By providing the sleeve ring, the rotation between the hand and the rotating handle is changed into the rotation between the sleeve ring and the rotating handle, so the operation is more convenient.
[0023] In a further technical solution, a lamp group is arranged at the bottom of the rack facing the test tube rack.
[0024] The setting of the light group allows the experimenter to see the status of the cell buckles in the test tube more clearly through supplementary light during the experiment, thus achieving better experimental results.
[0025] The beneficial effects are:
[0026] 1. The manual test tube shaker of the utility model arranges test tube clamps side by side on the test tube rack, and fixes the test tubes through the test tube clamps. Multiple test tubes can be fixed at one time, thereby ensuring the consistency of shaking. At the same time, when the test tube rack is shaken by a turntable, the amplitudes of all the parallel test tubes are consistent, further ensuring the consistency of shaking and reducing human errors.
[0027] 2. The setting of the jacket allows jackets of different sizes to be selected for installation according to the model of the test tube to be clamped, so that the clamping space matches the size of the test tube, ensuring the stability of the clamp arm in clamping the test tube.
[0028] 3. The setting of anti-slip pattern further improves the stability of the relative position between the test tube and the test tube clamp.
[0029] 4. The setting of the scale helps to determine the height of the test tube when it is clamped, so that all test tubes are at the same height, further ensuring the consistency of all test tubes when shaking.
[0030] 5. The turntable can be controlled by the handle, which is more convenient to operate.
[0031] 6. Since the operations of flushing the cell button and observing the discreteness are different, two rotating handles are set with different distances between the two rotating handles and the center of the circle to further facilitate the operation.
[0032] 7. By setting the sleeve ring, the rotation between the hand and the handle is changed to the rotation between the sleeve ring and the handle, which makes the operation more convenient.
[0033] 8. The setting of the light group allows the experimenter to see the state of the cell buckle in the test tube more clearly through supplementary light during the experiment, which leads to better experimental effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The utility model is further described below in conjunction with the accompanying drawings:
[0040] Example:
[0041] A manual test tube shaker, such as Figure 1 As shown, it includes a frame 10, on which a test tube rack 20 is arranged, and on which a plurality of test tube clamps 30 are arranged side by side;
[0042] Both ends of the test tube rack 20 are rotatably connected to the frame 10 , and one end of the test tube rack 20 extends out of the frame 10 and is connected to a turntable 40 .
[0043] In this embodiment, the number of the test tube clamps 30 is 12, and the 12 test tube clamps 30 are arranged in a row, and the arrangement direction of the 12 test tube clamps 30 is parallel to the rotation axis of the test tube rack 20.
[0044] The test tube clamp 30 includes a column 31, and the column 31 is fixed on the test tube rack 20. Figure 3 As shown, a clamping piece 32 is respectively provided on both sides of the column 31, and the middle parts of the two clamping pieces 32 are rotatably connected through the column 31, a wing edge 321 is provided on the same side of the two clamping pieces 32, and a clamping arm 322 is provided on the other opposite side of the two clamping pieces 32, and a torsion spring 33 is provided between the two wing edges 321.
[0045] The manual test tube shaker of the utility model is as follows Figure 2As shown, during operation, each test tube containing red blood cell solution is fixed in turn by the test tube clamp 30. Since the test tube clamp 30 itself is arranged side by side, the consistency of the position of each test tube is ensured. The clamping force applied by the torsion spring 33 is used to clamp the test tube. The test tube is highly stable and shaking can be started. During shaking, the test tube can be shaken by rotating the turntable 40. The amplitude of the test tubes with high stability and consistent position remains consistent. The amplitude and speed can be manually controlled during shaking to meet the different needs of flushing cell buckles and observing discreteness.
[0046] like Figure 1 As shown, although in this embodiment, the test tube passes through the hole on the test tube rack 20, the fixing method of the test tube clamp 30 of the utility model is different from the perforation-type test tube fixing method. The test tube is fixed by perforation. Since there is a gap between the hole and the test tube, the postures of each test tube are not completely consistent, which leads to the shaking of each test tube being out of sync when shaking uniformly, and there is also a shaking problem, resulting in errors. In this embodiment, the diameter of the hole is larger than the diameter of the test tube, the test tube is fixed by the test tube clamp 30, and the test tube is accurately positioned by two clamp arms 322, and the test tube does not contact the inner wall of the hole.
[0047] It is understandable that opening a hole on the test tube rack 20 is only one embodiment. The test tube clamp 30 can also be set at the edge of the test tube rack 20, and the test tube rack 20 has a notch corresponding to the test tube, which also does not affect the fixation of the test tube. The test tube rack 20 of the utility model only serves to install the test tube clamp 30 and drive the whole to shake, so it can have a variety of structural forms.
[0048] The manual test tube shaker of the utility model arranges test tube clamps 30 side by side on the test tube rack 20, and fixes the test tubes through the test tube clamps 30, so that multiple test tubes can be fixed at one time, thereby ensuring the consistency of shaking. At the same time, when the test tube rack 20 is shaken by the turntable 40, the amplitudes of all the parallel test tubes are consistent, which further ensures the consistency of shaking and reduces human errors.
[0049] In another embodiment, if Figure 3 As shown, the two clamp arms 322 are provided with removable clamping sleeves 323 on opposite sides thereof.
[0050] It is understandable that the detachable connection between the jacket 323 and the clamp arm 322 can be achieved by setting the edge of the jacket 323 to a soft rubber structure, and the jacket 323 is in the form of being sleeved on the clamp arm 322, which is convenient for disassembly and assembly.
[0051] Correspondingly, in other embodiments, the jacket 323 and the clamp arm 322 may be connected in a snap-fit manner or the like.
[0052] The setting of the jacket 323 allows jackets 323 of different sizes to be selected for installation according to the model of the test tube to be clamped, so that the clamping space matches the test tube size, and the clamping space and the test tube match closely, ensuring the stability of the clamp arm 322 in clamping the test tube.
[0053] In another embodiment, anti-slip grooves are provided on the opposite surface of the jacket 323 .
[0054] The provision of the anti-slip pattern further improves the stability of the relative position between the test tube and the test tube clamp 30 .
[0055] In another embodiment, if Figure 1 and Figure 2 As shown, a scale is provided on the column 31 , and the scale is arranged on the column 31 at a position higher than the clamping piece 32 .
[0056] It is understandable that the height of the conventional column 31 is comparable to that of the clamping piece 32. In this embodiment, the column 31 must first be raised, and the scale is set at the raised portion of the column 31, which is also the height at which the rear end of the test tube is fixed.
[0057] In the aforementioned embodiment, the height of the test tubes depends on the experimenter's visual leveling, and there may be a small error. In this embodiment, the experimenter aligns the ends of the test tubes with a ruler so that the heights of all the test tubes can be kept consistent more accurately.
[0058] It is understandable that the different heights of the test tubes affect the shaking in that the distance between the cell fluid and the center of the shaking circle is different, so the cell fluid is subjected to different moments, which affects the consistency of the experiment and introduces errors. Therefore, this embodiment accurately controls the height of the test tube to ensure the consistency of the experiment.
[0059] The setting of the scale helps to determine the height of the test tube clamp 30 when it is held, so that all test tubes are at the same height, further ensuring the consistency of all test tubes when shaking.
[0060] In another embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, a rotating handle is provided on the rotating disk 40 .
[0061] The turntable 40 is controlled to rotate by a turning handle, which is more convenient to operate.
[0062] Since the experimenter needs to observe the situation inside the test tube while operating the shaking, adding a rotating handle makes it easier for the experimenter to operate blindly.
[0063] In another embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the handle includes a first handle 41 and a second handle 42 , and the distance between the first handle 41 and the center of the rotating disk 40 is greater than the distance between the second handle 42 and the center of the rotating disk 40 .
[0064] Since the operations of flushing the cell button and observing the discreteness are different, the operation is further facilitated by setting two rotating handles with different distances between the two rotating handles and the center of the circle.
[0065] When flushing the cell buckle, it is gently and slowly shaken back and forth to allow the supernatant to flush the cell buckle, and the cell buckle is observed to fall off the bottom of the tube. At this time, the amplitude is large and the frequency is low, which is suitable for the first rotating handle 41. When observing dispersion, the test tube is gently shaken to observe the dispersion of the fallen cell buckle with the shaking. At this time, the shaking frequency is higher than the frequency of flushing the cell buckle, but the amplitude is smaller than the amplitude of flushing the cell buckle, which is suitable for the second rotating handle 42.
[0066] Different handles are selected according to the different operation requirements.
[0067] In another embodiment, if Figure 1 and Figure 2 As shown, a ring is sleeved on the handle.
[0068] By providing the sleeve ring, the rotation between the hand and the rotating handle is changed into the rotation between the sleeve ring and the rotating handle, so the operation is more convenient.
[0069] In another embodiment, if Figure 1 and Figure 2 As shown, a lamp assembly 50 is disposed at the bottom of the rack 10 toward the test tube rack 20 .
[0070] Since the test tubes themselves are relatively small and each test tube contains only 150 microliters of liquid plus red blood cells, it is difficult to observe clearly. Therefore, a light set 50 is provided. When conducting the experiment, the light set 50 is turned on and emits light upward. The light passes through the test tubes and the cell fluid therein, further facilitating observation.
[0071] The arrangement of the light group 50 enables the experimenter to see the state of the cell buckles in the test tube more clearly through supplementary light during the experiment, thereby achieving better experimental results.
[0072] 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, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
