Description

Technical Field

[0001] This application relates to the field of pipettes, and more specifically, to multichannel pipettes. Background Technology

[0002] A pipette is a precision tool widely used in laboratories, primarily for the accurate dispensing and transfer of minute amounts of liquid. A pipette mainly consists of a display window, volume adjustment components, a piston, an O-ring, a suction tube, and a pipette tip.

[0003] To improve experimental efficiency, reduce operational errors, and enhance experimental consistency, existing pipettes are typically equipped with multiple channels, usually 8 or 12 channels. Multiple channels allow for the transfer of multiple liquids in a single mechanical action, avoiding the risk of volume deviation or contamination introduced by multiple manual operations.

[0004] However, existing multichannel pipettes still have the following shortcomings in use: the distance between the tubes of existing multichannel pipettes is not easy to adjust, which results in different sizes of collection devices when multiple sets of tubes output liquid, and the output ends of multiple sets of tubes may not be able to be aligned with the collection device at the same time. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a multichannel pipette, which aims to improve the problem that the distance between the pipes is not easy to adjust, resulting in different sizes of collection devices when multiple sets of pipes output liquid, and the output ends of multiple sets of pipes may not be able to be aligned with the collection device at the same time.

[0006] This application provides a multichannel pipette, including a pipette body, eight sets of tubing for receiving and discharging liquids at the bottom of the pipette body, an adjustment mechanism for adjusting the spacing between the tubings at the bottom of the pipette body, and a sorting mechanism at the bottom of the pipette body.

[0007] The adjusting mechanism includes two sets of vertical plates, which are respectively connected to both sides of the infusion set body, and a first horizontal plate and a second horizontal plate are connected between the two sets of vertical plates.

[0008] In one specific implementation, a first sliding member is slidably connected to the outer surface of the first horizontal plate, a second sliding member is slidably connected to the outer surface of the second horizontal plate, a movable member is connected to one side of the first sliding member, and the movable member is connected to one side of the second sliding member.

[0009] In the above implementation process, the first sliding member can slide on the outer surface of the first horizontal plate by setting the first horizontal plate, thus limiting the sliding direction of the first sliding member. Similarly, the second sliding member can slide on the outer surface of the first horizontal plate by setting the second horizontal plate, thus limiting the sliding direction of the second sliding member.

[0010] In one specific implementation, a track plate is slidably inserted into the interior of the moving part, and eight sets of sliding grooves are opened through one side of the track plate. A protrusion is slidably connected inside the sliding groove, and one end of the protrusion is connected to one side of the moving part.

[0011] In the above implementation process, by setting the track plate, the track plate can move up and down inside the moving part, thereby driving the protrusion to move inside the sliding groove, thus driving the moving part to move. The moving part is connected to one side of the first sliding part and the second sliding part, so the movement of the moving part is restricted by the first horizontal plate and the second horizontal plate, and the moving part can only move horizontally left and right.

[0012] In one specific implementation, a fixing plate is connected to one side of the track plate, and a threaded seat is connected to one side of the fixing plate.

[0013] In the above implementation process, by setting the fixed plate, when the threaded seat moves up and down, it drives the fixed plate to move up and down, thereby driving the track plate to move up and down.

[0014] In one specific implementation, a housing is connected to one side of a set of vertical plates, a motor is connected to the top of the housing, the output shaft of the motor passes through the housing and is connected to a screw, and the other end of the screw is rotatably connected inside the housing.

[0015] In the above implementation process, by setting up a motor, the screw can be driven to rotate inside the housing by controlling the motor.

[0016] In one specific implementation, the threaded seat is threadedly connected to the outer surface of the screw, and the threaded seat is slidably connected to the inside of the housing.

[0017] In the above implementation process, the screw is connected to the threaded seat by a threaded connection, which can drive the threaded seat to move up and down inside the housing when the screw rotates, thereby driving the track plate to move up and down.

[0018] In one specific implementation, a connector is attached to one side of the movable component, and the connector communicates with the top of the pipe.

[0019] In the above implementation process, by setting up the connector, the connector can be moved together when the moving part moves, thereby adjusting the distance between the pipes.

[0020] In one specific implementation, the sorting mechanism includes multiple sets of first rigid tubes, the first rigid tubes being connected to the bottom of the pipette body and communicating with the pipette body, and the other end of the first rigid tubes being connected to a first flexible tube.

[0021] In the above implementation process, by setting the first hose, the first hose needs to undergo a certain deformation when adjusting the distance between the two sets of tubing in order to connect the tubing with the pipette body.

[0022] In one specific implementation, the top of the connector is connected to a third rigid tube, one end of the third rigid tube is connected to a second flexible tube, one end of the second flexible tube is connected to a second rigid tube, and the other end of the second rigid tube is connected to the other end of the first flexible tube.

[0023] In the above implementation process, by setting the second flexible tube, the distance between the two sets of tubes can be adjusted. The second flexible tube needs to undergo a certain deformation in order to connect the tube with the pipette body. By setting the first rigid tube, the second rigid tube and the third rigid tube, the first flexible tube and the second flexible tube can also ensure that the inside is unobstructed after being pulled by the spring.

[0024] In one specific implementation, a spring is connected to the outer surface of the second rigid tube, and a mounting plate is connected to the other end of the spring, the mounting plate being connected to the bottom of the pipette body.

[0025] In the above implementation process, by setting a spring, it is possible to position the pipe when it is in the middle of the pipeline. Figure 7 When in the middle position, the first and second hoses will be pulled by the spring, so that the first and second hoses are neatly arranged on one side of the mounting plate.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting the distance adjustment mechanism, the track plate can be moved up and down by controlling the motor, the protrusion can be moved left and right, the moving parts can be moved, and the pipes can be moved. This allows the distance between the pipes to be adjusted, thereby solving the problem that the distance between the pipes is not easy to adjust, which leads to the problem that when multiple sets of pipes output liquid, the size of the collection device is different, and the output ends of multiple sets of pipes may not be able to be aligned with the collection device at the same time.

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a multichannel pipette, including a pipette body 1.

[0039] Please see Figure 1 and Figure 2 The bottom of the pipette body 1 is provided with eight sets of tubing 4 for receiving and discharging liquids. The bottom of the pipette body 1 is provided with a spacing adjustment mechanism 2 for adjusting the spacing of the tubing 4. The bottom of the pipette body 1 is provided with a sorting mechanism 3.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7and Figure 8 Two sets of vertical plates 201 are respectively connected to both sides of the infusion set body, and a first horizontal plate 205 and a second horizontal plate 2010 are connected between the two sets of vertical plates 201.

[0041] In a specific configuration, a first sliding member 206 is slidably connected to the outer surface of the first horizontal plate 205, and a second sliding member 209 is slidably connected to the outer surface of the second horizontal plate 2010. A moving member 208 is connected to one side of the first sliding member 206, and the moving member 208 is connected to one side of the second sliding member 209. The first horizontal plate 205 allows the first sliding member 206 to slide on the outer surface of the first horizontal plate 205, thus defining the sliding direction of the first sliding member 206. Similarly, the second horizontal plate 2010 allows the second sliding member 209 to slide on the outer surface of the first horizontal plate 205, thus defining the sliding direction of the second sliding member 209.

[0042] In a specific configuration, a track plate 204 is slidably inserted into the interior of the movable component 208. Eight sets of sliding grooves 2012 are provided through one side of the track plate 204. A protrusion 207 is slidably connected inside the sliding groove 2012. One end of the protrusion 207 is connected to one side of the movable component 208. Through the arrangement of the track plate 204, the track plate 204 can move up and down inside the movable component 208, thereby driving the protrusion 207 to move inside the sliding groove 2012, thus driving the movable component 208 to move. The movable component 208 is connected to one side of the first sliding component 206 and the second sliding component 209. Therefore, the movement of the movable component 208 is restricted by the first horizontal plate 205 and the second horizontal plate 2010. The movable component 208 can only move horizontally left and right.

[0043] In a specific configuration, a fixing plate 2011 is connected to one side of the track plate 204, and a threaded seat 2014 is connected to one side of the fixing plate 2011. The fixing plate 2011 allows the threaded seat 2014 to move up and down, thereby causing the fixing plate 2011 to move up and down, which in turn causes the track plate 204 to move up and down.

[0044] In a specific configuration, a housing 203 is connected to one side of a set of vertical plates 201, and a motor 202 is connected to the top of the housing 203. The output shaft of the motor 202 passes through the housing 203 and is connected to a screw 2013. The other end of the screw 2013 is rotatably connected inside the housing 203. By setting up the motor 202, the screw 2013 can be rotated inside the housing 203 by controlling the motor 202.

[0045] In a specific configuration, the threaded seat 2014 is threadedly connected to the outer surface of the screw 2013, and the threaded seat 2014 is slidably connected to the inside of the housing 203. The threaded seat 2014 is threadedly connected to the screw 2013, so that when the screw 2013 rotates, the threaded seat 2014 can move up and down inside the housing 203, thereby driving the track plate 204 to move up and down.

[0046] In a specific configuration, a connector 5 is connected to one side of the movable component 208. The connector 5 is connected to the top of the pipe 4. By using the connector 5, the movable component 208 can move and drive the connector 5 to move together, thereby adjusting the distance between the pipes 4.

[0047] In a specific configuration, the sorting mechanism 3 includes multiple sets of first rigid tubes 302. The first rigid tubes 302 are connected to the bottom of the pipette body 1 and communicate with the pipette body 1. The other end of the first rigid tubes 302 is connected to a first flexible tube 303. The first flexible tube 303 is configured such that when the distance between the two sets of tubes 4 is adjusted, the first flexible tube 303 needs to undergo a certain deformation in order to connect the tubes 4 with the pipette body 1.

[0048] In the specific setup, the top of the connector 5 is connected to a third rigid tube 306, one end of the third rigid tube 306 is connected to a second flexible tube 307, one end of the second flexible tube 307 is connected to a second rigid tube 305, and the other end of the second rigid tube 305 is connected to the other end of the first flexible tube 303. The second flexible tube 307 is designed so that when the distance between the two sets of tubes 4 is adjusted, the second flexible tube 307 needs to undergo a certain deformation to connect the tube 4 with the pipette body 1. By setting the first rigid tube 302, the second rigid tube 305 and the third rigid tube 306, the first flexible tube 303 and the second flexible tube 307 can also be kept unobstructed after being pulled by the spring 304.

[0049] In a specific configuration, a spring 304 is connected to the outer surface of the second rigid tube 305, and a mounting plate 301 is connected to the other end of the spring 304. The mounting plate 301 is connected to the bottom of the pipette body 1, wherein the pipe 4 is located at... Figure 7 When in the middle position, the first hose 303 and the second hose 307 will be pulled by the spring 304, so that the first hose 303 and the second hose 307 are neatly arranged on one side of the mounting plate 301.

[0050] The working principle of this multichannel pipette is as follows: When using the multichannel pipette to extract the supernatant, the motor 202 drives the screw 2013 to rotate, which in turn moves the threaded seat 2014 up and down. This causes the track plate 204 to move up and down inside the moving part 208, which in turn moves the protrusion 207 inside the sliding groove 2012. This, in turn, moves the moving part 208. The moving part 208 is connected to one side of the first sliding part 206 and the second sliding part 209, so the movement of the moving part 208 is restricted by the first horizontal plate 205 and the second horizontal plate 2010. The moving part 208 can only move horizontally left and right. When the moving part 208 moves, it also moves the connecting part 5, thereby adjusting the distance between the pipes 4. Figure 7 When in the middle position, the first hose 303 and the second hose 307 will be pulled by the spring 304, so that the first hose 303 and the second hose 307 are neatly arranged on one side of the mounting plate 301.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
