Description

Technical Field

[0001] The invention relates to the field of sampling tubes, in particular to a sample detection sampling tube. Background Art

[0002] Most existing test sampling tubes and similar tools are composed of a test kit, a lysis solution tube, an injection head, and a swab stick. When performing sampling tests, the swab stick is used to wipe the location to be tested to obtain the swab stick with the sample, and then the swab stick is placed in the lysis solution tube, and then the lysis solution tube is manually squeezed to allow the sample to blend into the lysis solution. Finally, the injection head is installed and the sample is dripped into the sampling port of the test box to complete the test. The traditional sampling test process has the following problems:

[0003] The four parts need to be combined before use, and since the above parts are packaged separately, it will cause certain difficulties in distribution. During the assembly process, each part needs to be taken out separately, which poses a risk of contaminating the sample. The parts can be disassembled and used interchangeably after use. If the parts are reused, it will affect the actual test results and increase the risk of transmission. There are many operating steps during use, and a certain degree of precision is required. It is not convenient for children, the elderly, or some disabled people to operate, which affects the efficiency of use. The integrity of the recovery cannot be ensured, and it cannot be destroyed as a whole, which increases the risk of transmission. Summary of the invention

[0004] Based on this, it is necessary to provide a sample detection sampling tube to address the above-mentioned technical problems. The tube adopts an integrated connection structure and does not require independent packaging, which will not cause difficulties in distribution. Therefore, when taking out each part, there will be no hidden danger of contaminating the sample. At the same time, the components after use are basically unable to be completely disassembled, and the interchangeable use effect is poor. The risk of transmission of diseases and other harmful substances caused by reuse can be effectively avoided. The tube can be used to meet the needs of children, the elderly, or some disabled people, and can be destroyed as a whole.

[0037] Specifically, the sample detection sampling tube is placed vertically or tilted in the initial state. At this time, the sampling end of the sampling member 400 is located in the second limiting cavity 340, and the injection end of the sampling member 400 is located below the lysing liquid tube 200. The lysing liquid is gathered in the lysing liquid tube 200. When in use, the lysing liquid tube 200 is rotated to expose more of the injection end of the sampling member 400 to the outside. At this time, the sampling end of the sampling member 400 can be pushed away from the second limiting cavity 340 by the injection end, so that it can be easily contacted with the sampling point. After the sampling end contacts and completes sampling, the injection end is pulled downward to cause abutment between the sampling end and the rubber telescopic seat 300, and until the rubber telescopic seat 300 is pulled into the first limiting cavity 113, as shown in FIG. Figure 6 As shown, under the influence of pulling, the opening of the second limiting cavity 340 at the top of the rubber expansion seat 300 will approach each other and abut to complete the closure. At this time, the sample detection sampling tube is inverted to make the lysing liquid in the lysing liquid tube 200 flow into the first limiting cavity 113, and pass through the rubber expansion seat 300 and flow through the second limiting cavity 340. After the lysing liquid fully lyses the sample, the sampling part 400 is squeezed and the negative pressure adsorption effect is used to make the lysed sample liquid flow into the sampling part 400. Then, the sample detection sampling tube is placed upright. At this time, the sampling part 400 is squeezed to make the liquid obtained after lysing flow out to the specified position.

[0038] The above-mentioned sample detection sampling tube is placed vertically or tilted in the initial state. At this time, the sampling end of the sampling member 400 is located in the second limiting cavity 340, and the injection end of the sampling member 400 is located below the lysate tube 200. The lysate is gathered in the lysate tube 200. When in use, the lysate tube 200 is rotated to expose more of the injection end of the sampling member 400 to the outside. At this time, the sampling end of the sampling member 400 can be pushed away from the second limiting cavity 340 by the injection end, so that it can be easily contacted with the sampling point. After the sampling end contacts and completes sampling, the injection end is pulled downward to make the sampling end abut against the rubber telescopic seat 300, and until the rubber telescopic seat 300 is pulled into the first limiting cavity 113. At this time, under the influence of the pulling, the openings of the second limiting cavity 340 at the top of the rubber expansion seat 300 will approach each other and abut to complete the closure. At this time, the sample detection sampling tube is inverted to make the lysing liquid in the lysing liquid tube 200 flow into the first limiting cavity 113, and pass through the rubber expansion seat 300 and flow through the second limiting cavity 340. After the lysing liquid fully lyses the sample, the sampling piece 400 is squeezed and the negative pressure adsorption effect can be used to make the lysed sample liquid flow into the sampling piece 400. Then, the sample detection sampling tube is placed upright. At this time, the sampling piece 400 is squeezed to make the lysed liquid flow out to the specified position. The above-mentioned sample detection sampling tube adopts an integrated connection structure, and does not need to be packaged independently, which will not cause difficulties in distribution. Therefore, when taking it, there will be no hidden danger of contaminating the sample by taking out each part separately. At the same time, the various components after use can basically not be completely disassembled, and the interchangeable use effect is poor. The risk of transmission of diseases and other harmful substances caused by reuse can be effectively avoided. It can meet the operation requirements of children, the elderly, or some disabled people, and can be destroyed as a whole.
