Description

Technical Field

[0001] This utility model relates to the field of virus sample pipetting technology, and more specifically, to an auxiliary structure for a virus sample pipetting device. Background Technology

[0002] Lentivirals are a class of RNA viruses with reverse transcription properties. Their samples have important applications in gene therapy, cell biology research and other fields. In bioengineering, experiments such as lentivirus detection and culture require the use of pipettes to transfer samples. When aspirating liquid, disposable pipette tips are attached to the pipette tip to draw the sample into the tip, thus avoiding cross-contamination.

[0003] However, some pipette tips are typically only 3-5 cm long, while sample tubes are 7-8 cm long. When drawing samples, the pipette tip needs to be inserted about 2 cm below the sample liquid surface. When the pipette tip is shorter than the sample tube, the operator has to manually operate the pipette, which inevitably results in the pipette body touching the sample tube wall, causing contamination of the pipette body. This necessitates replacing the pipette and cleaning it, making the operation quite inconvenient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an auxiliary structure for a virus sample pipette, so as to solve the problem that when the pipette tip is shorter than the sample tube, the operator's manual operation of the pipette will inevitably result in the pipette body touching the sample tube wall, causing pipette body contamination, which leads to the need to replace the pipette and clean it, making the operation inconvenient.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an auxiliary structure for a virus sample pipette, comprising:

[0006] A base, on which a C-shaped top frame is fixedly installed by a vertical pole;

[0007] Fixed groove one, fixedly installed in the middle of the top surface of the base, a tube rack is detachably inserted in fixed groove one, and a plurality of fixed grooves two are evenly opened in the tube rack, a sample tube is detachably inserted in fixed groove two;

[0008] A slide rail rod parallel to the length direction of the tube rack is fixedly connected to the C-shaped top frame. The slide rail rod is equipped with a lifting and inserting assembly that can drive the pipette to move vertically up and down. The pipette is detachably installed on the lifting and inserting assembly, and the lifting and inserting assembly can slide along the slide rail rod.

[0009] The alignment and positioning component is capable of positioning the lifting and insertion component on the slide rail and aligning the pipette tip with the sample tube opening in the vertical direction.

[0010] Preferably, the lifting and inserting assembly includes a slide, which is slidably mounted on a slide rail. A limit rod is fixedly mounted on the top of the slide. A fixing box is provided above the slide, and a padding layer is provided inside the fixing box. The pipette is mounted in the fixing box through the padding layer. A side sliding lug is fixedly connected to the outside of the fixing box. The side sliding lug is slidably sleeved on the limit rod, and a spring is fitted on the limit rod between the slide and the side sliding lug. A U-shaped handrail is fixedly connected to the front of the slide, and a handle is fixedly connected to the front of the fixing box.

[0011] Preferably, the carriage, the fixing box, and the pad interlayer are all hollowed out in the middle, and the thickness of the pad interlayer first increases from top to bottom and then remains constant.

[0012] Preferably, the alignment and positioning assembly includes a switch and several magnetic blocks. The switch is located on the front side of the slide, and the several magnetic blocks are linearly distributed on the C-shaped top frame. Each magnetic block corresponds to a fixed groove. An electromagnet is provided on the side of the slide facing the magnetic blocks. The electromagnet is slidably installed in the slide via a telescopic column. A spring is fitted on the telescopic column. The two ends of the spring are fixedly connected to the electromagnet and the slide, respectively. The switch is electrically connected to the electromagnet.

[0013] Preferably, anti-slip pads are provided at all four corners of the bottom surface of the base.

[0014] Preferably, the tube rack has an observation port located on the front side of the second fixing groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention involves mounting a pipette on a lifting and inserting assembly, which moves along a slide rail to roughly position the pipette tip above the port of a sample tube. Then, an alignment and positioning assembly is used to precisely align the pipette tip with the center of the sample tube port. The lifting and inserting assembly is then operated to vertically insert the pipette tip into the sample tube to aspirate the sample. The above steps are repeated to inject the aspirated sample into another sample tube, thus completing the pipetting process. This allows for contactless alignment of the pipette tip as it enters and exits the sample tube, preventing the pipette body from contacting the inner wall of the sample tube and causing contamination.

[0017] This utility model utilizes a U-shaped handle to allow the slide to slide on the slide rail, adjusting the position of the pipette. The handle can drive the fixing box to descend vertically along the limiting rod, and the descent distance is controllable, making it easy for the operator to adjust the descent height of the pipette. Furthermore, the spring force can be used to automatically lift the pipette out of the sample tube, improving the overall convenience and operability of the structure.

[0018] This invention energizes the electromagnet by pressing a switch, which allows for further small-range adjustment of the slide position, enabling the electromagnet to move toward the magnetic block and be magnetically attracted and fixed, while ensuring relatively accurate alignment between the pipette and the sample tube.

[0019] This invention, through the design of the observation port, allows operators to clearly observe the label on the sample tube surface, thus avoiding pipetting errors. Attached Figure Description

[0029] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0030] As attached Figure 1 To be continued Figure 7This utility model provides an auxiliary structure for a virus sample pipette, including a base 1, on which a C-shaped top frame 3 is fixedly installed via a vertical rod 2; a first fixing groove 4, which is fixedly installed in the middle of the top surface of the base 1, and a tube rack 5 is detachably inserted in the first fixing groove 4; a plurality of second fixing grooves 6 are evenly opened in the tube rack 5, and a sample tube 7 is detachably inserted in the second fixing groove 6; a slide rail 8 parallel to the length direction of the tube rack 5, which is fixedly connected to the C-shaped top frame 3; a lifting and insertion assembly 9 on the slide rail 8 that can drive the pipette 10 to move vertically up and down; the pipette 10 is detachably installed on the lifting and insertion assembly 9, and the lifting and insertion assembly 9 can slide along the slide rail 8; and an alignment and positioning assembly 11, which can position the lifting and insertion assembly 9 on the slide rail 8 and align the pipette tip of the pipette 10 with the opening of the sample tube 7 in the vertical direction.

[0031] The pipe rack 5 can be quickly disassembled and assembled through the fixing groove 4, which facilitates cleaning and replacement of the pipe rack 5.

[0032] Specifically, by mounting the pipette 10 on the lifting and inserting assembly 9 and moving the lifting and inserting assembly 9 along the slide rail 8, the tip of the pipette 10 is roughly moved above the port of a sample tube 7. Then, the alignment and positioning assembly 11 is used to accurately align the tip of the pipette 10 with the center of the port of the sample tube 7. The lifting and inserting assembly 9 is then operated to vertically insert the tip of the pipette 10 into the sample tube 7 to aspirate the sample. Then, the above steps are repeated to operate the pipette 10 to inject the aspirated sample into another sample tube 7, thus completing the pipetting. Using the above structure, the tip of the pipette 10 can be aligned and inserted into the sample tube 7 without contact, preventing the pipette body of the pipette 10 from contacting the inner wall of the sample tube 7 and causing contamination of the pipette body.

[0033] Preferably, the lifting and inserting assembly 9 includes a slide 91, which is slidably mounted on the slide rail 8. A limit rod 92 is fixedly mounted on the top of the slide 91. A fixing box 93 is provided above the slide 91. A padding layer 94 is provided inside the fixing box 93. The pipette 10 is installed in the fixing box 93 through the padding layer 94. A side sliding lug 95 is fixedly connected to the outside of the fixing box 93. The side sliding lug 95 is slidably sleeved on the limit rod 92. A spring 96 is fitted on the limit rod 92 between the slide 91 and the side sliding lug 95. A U-shaped handle 97 is fixedly connected to the front of the slide 91. A handle bar 98 is fixedly connected to the front of the fixing box 93.

[0034] The U-shaped handle 97 allows the slide 91 to slide on the slide rail 8, adjusting the position of the pipette 10. The handle 98 can drive the fixing box 93 to descend vertically along the limiting rod 92, and the descent distance is controllable, making it easy for the operator to adjust the descent height of the pipette 10. Furthermore, the spring force of the spring 96 can automatically lift the pipette 10 out of the sample tube 7, improving the overall convenience and operability of the structure.

[0035] Preferably, the slide 91, the fixing box 93 and the padding layer 94 are all hollowed out in the middle, and the thickness of the padding layer 94 increases from top to bottom and then remains constant. The padding layer 94 can be used to clamp the pipette 10 in the fixing box 93, and the assembly and disassembly are simple and convenient.

[0036] Preferably, the alignment and positioning component 11 includes a switch 111 and several magnetic blocks 112. The switch 111 is located on the front side of the slide 91. The several magnetic blocks 112 are linearly distributed on the C-shaped top frame 3, and each magnetic block 112 corresponds to a fixed groove 6. An electromagnet 113 is provided on the side of the slide 91 facing the magnetic blocks 112. The electromagnet 113 is slidably installed in the slide 91 through a telescopic column 114. A spring 115 is fitted on the telescopic column 114. The two ends of the spring 115 are fixedly connected to the electromagnet 113 and the slide 91, respectively. The switch 111 is electrically connected to the electromagnet 113.

[0037] Among them, the switch 111 can be a push-button switch, which controls whether the electromagnet 113 is energized by pressing. The switch 111 and the electromagnet 113 are existing technologies, and their specific wiring and energizing methods and principles will not be described in detail. By setting the current, the magnetic force is large enough when the magnetic block 112 and the electromagnet 113 are magnetically attracted and fixed, so as to ensure the stability of the pipette 10 when the operating handle 98 is lowered.

[0038] Specifically, after the slide 91 moves the pipette 10 to the area above the target sample tube 7, press the switch 111 to energize the electromagnet 113. The position of the slide 91 can be further adjusted within a small range so that the electromagnet 113 moves toward the magnetic block 112 and is magnetically fixed, ensuring that the pipette 10 and the sample tube 7 are aligned relatively accurately. Conversely, when the power is off, the elasticity of the spring 115 can be used to separate the electromagnet 113 from the magnetic block 112.

[0039] Preferably, anti-slip pads 12 are provided at all four corners of the bottom surface of the base 1 to prevent slipping and improve the stability of the base 1.

[0040] Preferably, the tube rack 5 has an observation port 13 located in front of the fixing groove 6, which makes it easy for the operator to clearly observe the label on the surface of the sample tube 7 and avoid pipetting errors.
