Description

Method and apparatus for preventing misaddition of sample

Technical Field

The application relates to the technical field of sample detection, in particular to a method and a device for preventing a sample from being added by mistake.

Background

In various medical test items in hospitals, whether it is an assay for blood or body fluid, or an assay for patient excreta, it is generally necessary to perform an assay on a plurality of samples simultaneously in order to ensure stability of an assay result and perform a rapid assay, and thus, it is common to perform a concentrated assay by adding samples to a sample plate during an assay. For example, when performing certain biochemical tests using an enzyme-labeled instrument, a sample plate may be used to hold the sample and reagents to be assayed. For another example, in actual use, 96 samples may be assayed simultaneously using a sample plate of 96 sample wells. During use of the sample plate, it is generally necessary to sequentially add a plurality of reagents to the sample wells of the sample plate using a pipette. Because the number of sample holes and samples to be assayed on the sample plate is large, and the samples added in the sample holes are usually colorless liquid, an assaying person easily forgets which sample hole the sample is added in the last operation in the process of adding the sample to the sample plate by using a liquid shifter, and the repeated addition of the sample to the sample holes or the omission of the sample addition to a certain sample hole is easily caused.

Patent CN213475930U (application number: 202021666534.5) provides a 96-well plate mechanical error-proofing indicator, which comprises a base plate, a 96-well plate, a protruding strip and identification buttons, wherein a row type digital indicator is transversely arranged on the left and right direction of the end surface of the 96-well plate, a row type letter indicator is arranged on the up and down longitudinal direction of the end surface of the 96-well plate, a plurality of identification buttons are arranged on the base plate and transversely distributed in parallel, the plurality of identification buttons correspond to the row type digital indicator, and the identification buttons comprise an outer shell and an inner shell. The indicating button in the patent CN213475930U adopts a mechanical adjustment mode, so that omission or repeated sample adding in the operation process can be avoided, and adverse effects of light and electromagnetism on some cells and samples can be avoided. However, the indication button in CN213475930U requires manual rotation of the casing when switching between the first and second states during operation, so that the stopper moves along the vertical slot and cooperates with the first or second lateral limit slot, which results in a complex structure for preventing erroneous addition of the sample, and increases the workload when adding the sample into the sample hole, resulting in complicated operation when adding the sample into the sample hole, and is not suitable for use in actual sample assay work.

Fig. 1 is a schematic flow chart of a method for preventing a sample from being added by mistake in the embodiment of the present application, and as shown in fig. 1, the method for preventing a sample from being added by mistake provided in the embodiment of the present application includes S110 to S130, and S110 to S130 are specifically described below.

S110, when a target sample is added to the target sample hole of the sample plate 1, a pipetting signal is sent out by the emitting component 21 on the pipettor 2.

Fig. 2 is a schematic front view of a method for preventing a sample from being added by mistake in the embodiment of the present application, and as shown in fig. 2, a sample plate 1 is of a transparent structure, and a plurality of sample holes 11 are provided on the sample plate 1, and the plurality of sample holes 11 are used for respectively holding samples for sample assay and detection.

In use, a sample, typically a liquid, may be added to the sample plate 1 via the pipette 2.

In use, when a target sample is added to a target sample hole of the sample plate 1 through the pipette 2, the emission component 21 on the pipette 2 sends out a pipetting signal, and the subsequent pipetting signal sent out by the emission component 21 can prevent the erroneous addition of the sample.

S120, receiving the pipetting signals by the target receiving assembly corresponding to the target sample hole.

Fig. 3 is a schematic partial structure at a point a of the method for preventing the erroneous addition of a sample in fig. 2, and structurally, as shown in fig. 2 and 3, each sample hole 11 on the sample plate 1 corresponds to one receiving component 31, so that a pipetting signal can be received by the corresponding receiving component 31 of each sample hole 11, and further, the erroneous addition of a sample can be prevented by receiving the pipetting signal.

When the sample receiving device is used, after the target receiving component corresponding to the target sample hole receives the pipetting signals, the samples can be prevented from being added by mistake according to the pipetting signals received by the target receiving component corresponding to each target sample hole, and further, the samples can be prevented from being added by mistake accurately for each sample hole 11.

When the device is used, only the target receiving components corresponding to the target sample holes can be controlled to be in an electrified state, the receiving components 31 except the target receiving components corresponding to the target sample holes are kept in a power-off state, further, only the target receiving components corresponding to the target sample holes can be controlled to receive pipetting signals, all the other sample holes 11 do not receive pipetting signals, at the moment, only one target sample hole exists, and a user can add a target sample into the target sample hole. Since the transmitting component 21 is fixedly connected to the liquid dispenser 2, when the liquid dispenser 2 is used, the liquid dispenser 2 is only required to be held in a fixed posture, then the liquid outlet of the liquid dispenser 2 is aligned to the target sample hole, and the transmitting component 21 of the liquid dispenser 2 is aligned to the target receiving component, so that the sample in the liquid dispenser 2 can be smoothly added into the target sample hole, and the liquid dispenser signal is received by the target receiving component corresponding to the target sample hole.
