Problems solved by technology

[0002] At present, a single pipette is mainly used in the biochemical laboratory, and the pipetting operation is completed manually, and the sample is exposed to the air during the extraction process. The transfer and detection of pathogens of viruses and other diseases will easily increase the risk of virus infection for testers in an open environment. Therefore, it needs to be operated by professionals in the PCR laboratory, which is not easy to meet the needs of large-scale testing.
Although there are reports of some closed sample extraction devices in the prior art, gas will be generated during the sample extraction process, so these devices are also equipped with vent pipes or vent pools for exhaust, and cannot truly achieve a fully sealed state for sample extraction.

Embodiment 1

figure 1 A front view of the sample extraction device of the present disclosure is shown. figure 2 An exploded view of the sample extraction device of the present disclosure is shown. image 3 A schematic diagram showing the A and B sides of the base body of the present disclosure. Figure 4 A perspective view showing side A of the sample extraction device of the present disclosure. Figure 5 A perspective view showing the B side of the sample extraction device of the present disclosure.

[0059] like Figure 1 to Figure 5 As shown, the sample extraction device 1 includes: a base 10 and a plurality of chambers S disposed on the base 10 . The base 10 is provided with a first passage L1 and a second passage L2. The first passage L1 and the second passage L2 are pipes for fluids such as liquids and gases to pass through. The second passage L2 is used for the transfer of liquids such as samples and reagents. Specifically, the base 10 includes a base body 11 and an outer shiel...

Figure 8 A front view of another sample extraction device of the present disclosure is shown. Figure 9 An exploded view showing another sample extraction device of the present disclosure. Figure 10 Schematic diagrams showing surfaces A and B of another base body of the present disclosure. Figure 11 A perspective view showing side A of another sample extraction device of the present disclosure. Figure 12 A perspective view showing the B side of another sample extraction device of the present disclosure.

[0089] like Figure 8 , Figure 9 As shown, the sample extraction device 2 provided by the present disclosure is Figure 1-5 The difference of the sample extraction device shown is that the first sample adding tube S3 and the sample adding flow channel L3 are not used when adding the sample, but one of the first chambers S1 is used as the sample adding tube. Specifically, a branch pipe S4 is provided on the side wall of the first chamber S1, and sample addition is re...

Abstract

The present disclosure provides a sample extraction device, comprising: a plurality of chambers arranged on a base, the chambers comprising a plurality of first chambers and two mixing chambers; a first passage is arranged in the base and is used for communicating the two mixing chambers, and a sample extraction chamber is arranged in the first passage; a second passage is further arranged in the base and used for transferring and guiding out liquid, and the two mixing chambers are controlled by valves to be connected and disconnected with the second passage. According to the technical scheme, the sample extraction process is carried out in the totally-closed device, so that the sample and the extraction reagent are prevented from being polluted by the external environment, the pollution of aerosol generated in the sample extraction process to the environment is also avoided, and the device is particularly suitable for extraction of high-pathogenicity samples.

Description

technical field [0001] The present disclosure relates to the technical field of biomedical instruments, in particular to a sample extraction device. Background technique [0002] At present, a single pipette is mainly used in the biochemical laboratory. The pipetting operation is completed manually. During the extraction process, the sample is exposed to the air. The transfer and detection of pathogens of viruses and other diseases can easily increase the risk of infection of the virus by the testing personnel in an open environment. Therefore, it needs to be operated by professionals in the PCR laboratory, which is not convenient to meet the needs of large-scale testing. Although there are some reports of closed sample extraction devices in the prior art, gas is generated during the sample extraction process. Therefore, these devices are also equipped with ventilation pipes or ventilation pools for exhausting, which cannot truly achieve a fully sealed state for sample extra...
