Definitions
- Dispensing device that can move to rectangular coordinates and cylindrical coordinates
- the present invention relates to a dispensing apparatus in which a mechanism for extending an operating range of an electric pipe and a mechanism for selecting a size of a piston pump incorporated in the electric pipe are combined. .
- liquids such as samples and reagents are sucked in an arbitrary amount into a container set in a predetermined position, and set in another predetermined position.
- a dispensing device using an electric pit for discharging into a container has become indispensable.
- the electric pit has the basic structure shown in FIG. It is possible to aspirate samples and reagents directly into the cylinder 2 of the motorized pipe, but if contamination (cross-contamination) when dispensing different samples or reagents becomes a problem, the piston Generally, a nozzle 4 is provided at the tip of the pump, a disposable tip 5 is attached to the nozzle 4, and a liquid 6 such as a sample or a reagent is sucked into the tip 5.
- the electric pit is mounted on a drive mechanism that can move the rectangular coordinates as shown in FIG. In the dispensing device, the liquid suction position, suction amount, discharge position, and discharge amount can be programmed in advance, and the liquid sorting operation can be automated.
- Dispensing devices are widely used in various fields such as medical, pharmaceutical, and biotechnology, which automatically and accurately sort liquid into precise locations (containers).
- high speed and accuracy are required for liquid sorting.
- the high speed depends on the operating speed of the drive system for moving the electric pits and the number of electric pits.
- the former is determined by the performance of the motor of the drive unit, the reduction ratio, and the like.
- the latter type which uses a plurality of electric pits, is generally called a multi-channel type, and 4, 8, 12, and 96 channel types are commercially available.
- Accuracy depends not only on the accuracy of the piston pump drive inside the electric pipe, but also on the outside diameter of the piston and the dead volume of the tip that can be attached to the nozzle. You. That is, a small amount of liquid cannot be accurately dispensed with a piston pump having a large outer diameter or a tip having a large volume. This is because dispensing using a piston pump utilizes the change in the volume of air in the piston pump.
- the normal dispensed liquid volume can be divided into three stages, from around 0.5 H1 to around 101, around 5 n1 to around 201, and around 1001 to around 1001.
- different sized tips are used at each stage to dispense the correct volume. Since the tip is different, the nozzle and piston pump provided in the electric pipette are also different. That is, the shape of the electric pipette is different. That is, in order to accurately dispense the liquid volume from 0.51 to 1 001, a plurality of motorized pipes are required.
- dispensing devices that automatically change dispensing units having different shapes (corresponding to the electric pits in this patent). Conventional dispensers have been pursued with multi-channels for high-speed dangling, and performance such as an automatic exchange mechanism for the motor-driven pipe section to ensure accuracy. It pursues a single function as a so-called dispensing device.
- the current Lapoportion is a large-scale combination of a dispensing device and a pot for industrial use such as automobile manufacturing. That is, a transfer port pot is used to transfer containers containing samples and reagents before and after dispensing between a dispensing device, a reaction device, and an analyzer. Dispensing, reaction, and analysis steps are blocked, and a series of steps can be processed continuously by moving containers such as liquids.
- Figure 1 shows the outline of a piston pump.
- Reference numerals 1 to 6 in FIG. 1 mean the following.
- Fig. 2 shows the outline of a conventional dispenser.
- FIG. 3 shows an outline of the basic mechanism of the present patent.
- the symbols 1 to 5 in FIG. 3 mean the following.
- FIG. 4 shows an application example of the basic mechanism of the present patent.
- Reference numerals 1 to 7 in FIG. 4 mean the following.
- FIG. 5 shows an application example of the basic mechanism of the present invention.
- Reference numerals 1 to 2 in FIG. 5 mean the following.
- the present invention is a dispensing device that can realize automation in small and medium-sized labs and improve functions and performance according to the scale and budget of an automatic tech while improving the above-mentioned problems.
- the operating area of the electric pipette that is, the drive system on which the electric pipette is mounted is composed of three axes: front, rear, left, right, and up and down. ).
- the operating area of the electric pit has been successfully expanded by combining an operating mechanism that can move the rectangular coordinates and the cylindrical coordinates.
- the mechanism that can move to Cartesian coordinates is a motor used in conventional dispensers.
- a mechanism that converts rotational motion into linear motion is used.
- the mechanism that can move to cylindrical coordinates is a mechanism that reduces the rotational motion of the motor and transmits it as rotational motion.
- a basic drive system in which the electric pipette unit is attached to a linear drive mechanism capable of moving one or the other, or two, or three, in the front-back, left-right, up-down directions, is assembled.
- the basic drive system is mounted on a rotatable drive mechanism, and the rotatable drive mechanism is mounted on a drive mechanism movable in a direction that cannot be moved by the basic drive system.
- any of them can achieve an operating mechanism that can move rectangular coordinates and cylindrical coordinates. With this method, the operating range of the electric nozzle can be extended.
- the motor shaft 4 is mounted on the vertical shaft 3, the upper and lower shaft 3 is mounted on the left and right shaft 1, the left and right shaft 1 is mounted on the rotating shaft 5, and the rotating shaft 5 is mounted on the front and rear shaft 2. It is an example of the present invention.
- the function can be extended as shown in Fig. 4.
- a separate transport system and dispensing device are required to transfer samples and the like from the conventional dispensing device to an analyzer such as the microplate reader 7 shown in FIG.
- the rotating shaft 5 is rotated. The transfer of the sample to the microplate reader 7 can be easily realized only by the above.
- FIG. 5 an example of the dispensing device according to claim 6 is shown in FIG.
- FIG. 5 it is possible to automate a plurality of work stages 2 continuously only by the basic mechanism 2 of the present invention.
- a mechanism for automatically exchanging dispensing sections having different shapes (corresponding to an electric pipette in the present patent), as described in Japanese Laid-Open Patent Publication No. Hei 8-2-22944, may be mentioned.
- '' According to the present invention, it is possible to implement a dispensing device capable of realizing automation in small and medium-sized labs and improving functions and performance according to the scale and budget of automation.
