For example, the bottom end of the pipette is inserted into the refrigerating chamber, and the sealing assembly comprises a sealing ring pipe and a pressure air pump, wherein the sealing ring pipe is arranged in the pipette hole and is sleeved on the peripheral surface of the pipette. For example, the pressure-sustaining air pump is mounted on the top surface of the refrigerator and is connected to the sealed collar for pumping pressure-sustaining air into the sealed collar.
Referring to fig. 1 to 5, a reagent bottle refrigerating and liquid sucking temporary storage system comprises a cooling base 30, a refrigerating box 40, a liquid sucking assembly 50 and a sealing assembly 60, wherein the refrigerating box 40 is mounted on the cooling base 30, a refrigerating chamber 45 is formed in the refrigerating box 40, a liquid sucking hole is formed in the top of the refrigerating box 40, the liquid sucking assembly 50 comprises a temporary storage cabinet 51, a rotary cylinder 52, a first screw 53, a sliding seat 54 and a liquid sucking pipe 55, the temporary storage cabinet 51 is mounted on the top of the refrigerating box 40, the rotary cylinder 52 is mounted on the top of the temporary storage cabinet 51, the first screw 53 is connected to an output shaft of the rotary cylinder 52, the sliding seat 54 is screwed on the first screw 53 and is slidably disposed on the temporary storage cabinet 51, an L-shaped sheet metal part 56 is disposed on one side of the sliding seat 54, and the liquid sucking pipe 55 is mounted on the sheet metal part 56, the middle of the pipette 55 is slidably inserted into the pipette hole, the bottom end of the pipette 55 is inserted into the refrigerating chamber 45, the sealing assembly 60 includes a sealing ring tube 61 and a pressure-holding air pump 62, the sealing ring tube 61 is installed in the pipette hole and is sleeved on the peripheral surface of the pipette 55, and the pressure-holding air pump 62 is installed on the top surface of the refrigerator 40 and is connected with the sealing ring tube 61 for pumping pressure-holding air into the sealing ring tube 61.
When the reagent bottle refrigerating and temporary pipette storage system is used, the reagent bottles containing reagent samples such as latex reagents, blood samples or biological agents are refrigerated in the refrigerating box 40. When a sample needs to be sucked, the rotating cylinder 52 drives the first screw 53 to rotate, so as to drive the sliding seat 54 to move downwards along the temporary storage cabinet 51, drive the pipette 55 to descend and insert into the reagent bottle, so as to suck a reagent, and extract the reagent for an experiment. Since the refrigerating chamber 40 does not need to be opened frequently every time reagent is sucked, the entrance of external hot air is prevented, and the refrigerating effect is improved.
For example, in order to improve the cooling effect, the cooling base 30 includes a heat dissipation fan 31, a heat dissipation frame 32 and a cooling fin 33, the heat dissipation frame 32 is mounted on the top of the heat dissipation fan 31, and the cooling fin is mounted on the top surface of the heat dissipation frame 32. The heat dissipation frame 32 includes a plurality of heat dissipation fins, the plurality of heat dissipation fins are arranged in parallel at intervals, and the refrigeration container 40 is installed on the refrigeration sheet 33. The refrigerating compartment 40 includes a main compartment 41 and a door 43, the refrigerating chamber 45 is formed in the main compartment 41, and the door 43 is rotatably mounted on the main compartment 41. A card reader is arranged in the cabinet door 43. For example, the cooling plate 33 is a semiconductor cooling plate 33. By arranging the refrigerating sheet 33 and the heat radiation fan 31, the refrigerating effect can be improved. The card reader can read the label on the reagent bottle, and when the reagent is sucked each time, the card reader records the sucking times, so that whether the upper limit of the preset sucking times is reached is judged, and whether the reagent bottle needs to be replaced is further judged.
For example, to facilitate improved sealing, the seal assembly 60 further includes a mounting seat 63, the mounting seat 63 being mounted in the fluid-intake bore. The sealing ring pipe 61 is installed in the installation seat ring 63, and the pressure air pump 62 is connected with the sealing ring pipe 61 through a connecting pipe 64. The connecting tube 64 is inserted into the mounting collar 63, and the outer diameter of the mounting collar 63 is larger than the outer diameter of the sealing collar 61. An annular groove 635 is concavely arranged on the inner peripheral surface of the mounting seat ring 63, the cross section of the annular groove 635 is circular, and the sealing ring pipe 61 is mounted in the annular groove 635. One side of the annular groove 635 is formed with a slit 638, which allows an inner circumferential surface portion of the sealing collar 61 to be exposed outside the mounting seat 63. The width of the slit 638 is smaller than the radius of the cross section of the annular groove 635, and the sealing collar 61 is a flexible tube, and an annular inflation channel 615 is formed therein, and the annular inflation channel 615 is communicated with the connection tube 64. By providing the mounting seat 63, the suction pipe 55 can be guided to smoothly move up and down. The provision of the annular groove 635 facilitates the installation of the sealing collar 61.
For example, the pipette 55 is a hard pipe, and a flexible pipe joint 555 is provided at a lower portion of the pipette 55. The flexible tube segments 555 are located within the refrigeration cavity 45. The pressurization pump 62 is used to drive the sealing collar 61 to contract when the pipette 55 is inserted, so that the pipette 55 is smoothly moved downward. After the liquid suction is finished, the first screw 53 is used for driving the liquid suction pipe 55 to move upwards through the sliding seat 54 to return to the original position, so that the flexible pipe joint 555 moves upwards to the sealing ring pipe 61, and the pressure air pump 62 is used for forcing the sealing ring pipe 61 to expand so as to clamp the flexible joint, and further clamp the liquid suction pipe 55, so that the sealing effect of the liquid suction pipe 55 is improved. By the contraction and expansion of the sealing collar 61, the downward and upward movement and sealing of the pipette 55 are facilitated, and the sealing effect is improved.
For example, in an embodiment, after a reagent is sucked, a certain sample needs to be temporarily stored in the temporary storage cabinet 51 at some time, a storage cavity is formed in the temporary storage cabinet 51, an opening is formed in one side of the temporary storage cabinet 51, two vertical partition plates 57 are arranged in the storage cavity, the two vertical partition plates 57 are respectively arranged on two opposite sides of the first lead screw 53, so that the storage cavity is divided into two side cavities and a middle cavity, the side cavities are located between the vertical partition plates 57 and corresponding side walls of the storage cavity, and the middle cavity is located between the two vertical partition plates 57. The first lead screw 53 is located in the intermediate cavity. The opposite two sides of the sliding seat 54 are respectively provided with a groove, the opposite two side walls of the temporary storage cabinet 51 are respectively clamped into the two grooves, so that the sliding seat 54 is blocked at the opening, the bottom of the sliding seat 54 is provided with an elastic sealing sheet 58, and the bottom end edge of the elastic sealing sheet 58 is connected to the top of the refrigerating box 40. The sliding seat 54 is used to drive the elastic closing piece 58 to extend to close the storage cavity when moving upwards.
For example, an upper partition plate 511 and a lower partition plate 512 are fixedly arranged in each side cavity. The upper partition plate 511 and the lower partition plate 512 are both provided with through holes. The bottom of the upper partition plate 511 and the bottom of the lower partition plate 512 are both provided with a flexible sealing layer. For example, in order to temporarily store some sample reagents, the top end of the first lead screw 53 is fixedly sleeved with a driving gear, the reagent bottle cold storage and liquid absorption temporary storage system further comprises a lifting assembly 70, and the lifting assembly 70 comprises two driven gears 78, two second lead screws 71 and two supporting plate groups. The two driven gears 78 are respectively engaged with two opposite sides of the driving gear, the two second lead screws 71 are respectively inserted into the two side cavities, each second lead screw 71 is arranged in the through hole of the upper partition 511 and the through hole of the lower partition 512 in a penetrating manner, and the top end of each second lead screw 71 is fixedly inserted into the center of the corresponding driven gear 78. Each supporting plate group is installed in a corresponding side cavity, each supporting plate group comprises an upper supporting plate 72 and a lower supporting plate 73, the upper supporting plate 72 is located between the upper partition plate 511 and the lower partition plate 512, the lower supporting plate 73 is located below the lower partition plate 512, and the upper supporting plate 72 and the lower supporting plate 73 are screwed on the second screw rod 71. The periphery of the upper partition plate 511 and the periphery of the lower partition plate 512 are both formed with vertical surrounding edges, and the vertical surrounding edges are slidably abutted against the side walls of the side cavity. Due to the arrangement of the upright surrounding edges, the upper supporting plate 72 and the lower supporting plate 73 are not easy to incline when ascending and descending.
After the pipette 55 aspirates the reagent, if temporary storage of the reagent is desired, the aspirated reagent sample may be placed into a vessel, such as a beaker. The upper supporting plate 72 and the lower supporting plate 73 are used for temporarily storing utensils, and the utensils are kept away from the second screw rod 71. The rotary cylinder 52 is used for driving the two driven gears 78 to rotate through the driving gear, and then the two second screw rods 71 drive the upper support plate 72 and the lower support plate 73 to move upwards, so that the top opening of the vessel is sealed by the flexible sealing layer of the upper partition 511 or the flexible sealing layer of the lower partition 512. That is, the top opening of the vessel on the upper support plate 72 is closed on the bottom surface of the upper partition 511, and the top opening of the vessel on the lower support plate 73 is closed on the bottom surface of the lower partition 512. For example, the top of the two vertical partition plates is formed with an avoidance gap for avoiding the driving gear and the two driven gears. For example, in order to facilitate the up-and-down position limitation of the upper support plate 72/the lower support plate 73, the second lead screw 71 has an upper screw segment 711 and a lower screw segment 713 on the region between the upper partition 511 and the lower partition 512, the upper screw segment 711 is located above the lower partition 512, the lower screw segment 713 is aligned with the lower partition 512, and the upper support plate 72 is used for lifting and lowering between the upper screw segment 711 and the lower screw segment 713. Specifically, the upper support plate 72 is driven by the second screw 71 to rise to the upper screw segment 711 and maintain the position (because the upper support plate 72 does not engage with the screw thread on the upper portion of the upper screw segment 711 under the action of gravity, so that the second screw 71 idles), so that the top opening of the vessel is closed on the flexible sealing layer of the upper partition 511. After that, the first lead screw 53 continues to drive the sliding seat 54 to drive the elastic sealing sheet 58 to seal the opening of the temporary storage cabinet 51. When the upper support plate 72 is driven by the second lead screw 71 to move downwards (the upper support plate 72 gradually engages with the threads on the lower part of the upper lead screw section 711 under the action of gravity) to the lower lead screw section 713 and is supported on the lower partition 512 (the upper support plate 72 does not engage with the threads on the lower part of the lower lead screw section 713 under the support of the lower partition 512, so that the second lead screw 71 idles), and the position is maintained until the slide seat 54 drives the elastic closing piece 58 to open the opening of the temporary storage cabinet 51. Similarly, the second lead screw 71 and the lower support plate 73 are also matched in structure, so that the lower support plate 73 can also ascend and descend in a section to match the closing and opening of the temporary storage cabinet 51. By arranging the lifting assembly 70, the liquid sample sucked by the liquid suction pipe 55 can be temporarily stored in the temporary storage cabinet 51, and the upper support plate 72 and the lower support plate 73 can easily close the top opening of the vessel and allow the sliding seat 54 to continue to drive the elastic closing piece 58 to close the opening of the temporary storage cabinet 51.
