Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling tubes, in particular to a high-efficiency sampling tube with a refrigeration function. Background Art
[0002] The main function of the sampling tube is to preserve and transport sampling samples, such as those used for collecting 2019-nCov, influenza virus, hand, foot and mouth disease, measles and rubella, norovirus, rotavirus and related samples. They usually need to be stored and transported at a temperature of 2-8°C.
[0003] Existing sampling tubes are generally composed of a tube body, a sealing cover, and a sampling head. The tube body is usually made of high-quality materials, such as stainless steel, plastic (such as polypropylene, polyethylene), glass, etc., to ensure the integrity and stability of the sample. However, the existing sampling tubes themselves do not have a refrigeration function. After the sampling is completed, the staff needs to place the sampling tube inside a designated refrigeration device, but the refrigeration device is generally large in size and inconvenient to carry. Therefore, during the process of placing the sampling tube inside the designated refrigeration device, the sample inside the sampling tube is easily changed under the influence of high temperature weather, which in turn affects the subsequent analysis of the sample, resulting in poor practicality. Utility Model Content
[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide an efficient sampling tube with a refrigeration function, which can solve the problem that the existing sampling tubes do not have a refrigeration function.

[0029] See also Figure 1-6 The utility model provides a technical solution: a high-efficiency sampling tube with a refrigeration function, comprising a first thermal insulation box 1, the lower surface of the first thermal insulation box 1 is fixedly connected to a first connecting sleeve 9 communicated with it, the inner wall of the first connecting sleeve 9 is provided with a second thread 10, the lower surface of the first thermal insulation box 1 is provided with a second thermal insulation box 5, and the upper surface of the second thermal insulation box 5 is fixedly connected to a second connecting sleeve 15 communicated with it.
[0030] The outer wall of the second connecting sleeve 15 is provided with a fourth thread 16 adapted to the second thread 10 , and the top of the first thermal insulation box 1 is fixedly connected with a sampling tube 6 .
[0031] Furthermore, the upper end of the sampling tube 6 passes through the upper surface of the first thermal insulation box 1 , the outer wall of the sampling tube 6 is provided with a first thread 8 , and the inner wall of the first thread 8 is fixedly connected with a sealing gasket 7 .
[0032] Furthermore, a heat-insulating cover 4 is provided on the upper surface of the first heat-insulating box 1 , an annular groove 13 is provided on the lower surface of the heat-insulating cover 4 , and a third thread 14 adapted to the first thread 8 is provided on the inner wall of the annular groove 13 .
[0033] Furthermore, a protection box 2 is fixedly connected to the rear surface of the first heat-insulating box 1 , and a plurality of through holes 3 communicating with the protection box 2 are formed on the upper surface thereof.
[0034] Furthermore, a connecting pipe 11 communicating therewith is fixedly connected to the rear surface of the first heat-insulating box 1 , and a micro pressure-relief pump 12 communicating therewith is fixedly connected to the upper end of the connecting pipe 11 .
[0035] Furthermore, the micro pressure relief pump 12 and the connecting pipe 11 are both located inside the protective box 2, and the second semicircular block 21 is fixedly connected to the rear inner wall of the sampling tube 6, and a semicircular groove 17 is provided on the front surface of the second semicircular block 21. The first semicircular block 20 is fixedly connected to the front inner wall of the sampling tube 6, and the rear end of the first semicircular block 20 is tilted upward. The first semicircular block 20 is located on the upper side of the second semicircular block 21, and a rectangular groove 18 is provided on the rear surface of the first semicircular block 20. The inner wall of the rectangular groove 18 is fixedly connected to a breaking plate 19.
[0036] Furthermore, when using a high-efficiency sampling tube with a refrigeration function, when sampling is first performed, the staff rotates the insulation cover 4 to disengage the first thread 8 from the third thread 14, and then the staff can tilt the swab with the microbial sample to be sampled through the inner wall of the semicircular groove 17 into the interior of the sampling tube 6. The swab contacts the inner wall of the semicircular groove 17 and moves downward. After moving to the designated position, the staff bends the swab forward, and the front surface of the swab contacts the rear end of the breaking plate 19, while the rear surface of the swab contacts the inner wall of the semicircular groove 17. Under strong pressure, the swab breaks. By setting the first semicircular block 20 and the second semicircular block 21, the interval between the first semicircular block 20 and the second semicircular block 21 blocks the swab, thereby preventing the part of the swab located in the tube body from bending and rebounding after breaking, which easily causes the sampling reagent and human secretions to pop out. Then the insulation cover 4 is fixedly installed together with the first insulation box 1 through the first thread 8 and the third thread 14;
[0037] The staff then twists the second heat-insulating box 5 through the second thread 10 and the fourth thread 16 to separate the second connecting sleeve 15 from the inner wall of the first connecting sleeve 9. The staff then puts the dry ice they carry into the interior of the second heat-insulating box 5 through the second connecting sleeve 15, and then fixes the second heat-insulating box 5 to the first heat-insulating box 1 through the second thread 10 and the fourth thread 16.
[0038] Among them, by placing dry ice inside the second thermal insulation box 5, the dry ice sublimates and absorbs the heat inside the first thermal insulation box 1, so that the temperature inside the first thermal insulation box 1 is reduced, thereby achieving the effect of refrigerating the microorganisms inside the sampling tube 6, thereby improving the practicality of the high-efficiency sampling tube;
[0039] Among them, by setting up the connecting pipe 11 and the micro pressure relief pump 12, when the carbon dioxide pressure inside the first insulation box 1 is too high, the micro pressure relief pump 12 will automatically open to automatically relieve the pressure inside the first insulation box 1, thereby improving the safety of the high-efficiency sampling tube when in use.
[0040] Working principle: When using a high-efficiency sampling tube with a refrigeration function, when sampling, the staff first rotates the insulation cover 4 to disengage the first thread 8 and the third thread 14. Then the staff can tilt the swab with the microbial sample to be sampled into the interior of the sampling tube 6 through the inner wall of the semicircular groove 17. The swab contacts the inner wall of the semicircular groove 17 and moves downward. After moving to the designated position, the staff bends the swab forward, and the front surface of the swab contacts the rear end of the breaking plate 19. At the same time, the rear surface of the swab contacts the inner wall of the semicircular groove 17. Under strong pressure, the swab breaks. By setting the first semicircular block 20 and the second semicircular block 21, the interval between the first semicircular block 20 and the second semicircular block 21 blocks the swab, thereby preventing the part of the swab located in the tube body from bending and rebounding after breaking, which may easily cause the sampling reagent and human secretions to pop out. Then the insulation cover 4 is fixed to the first insulation box 1 through the first thread 8 and the third thread 14;
[0041] The staff then twists the second heat-insulating box 5 through the second thread 10 and the fourth thread 16 to separate the second connecting sleeve 15 from the inner wall of the first connecting sleeve 9. The staff then puts the dry ice they carry into the interior of the second heat-insulating box 5 through the second connecting sleeve 15, and then fixes the second heat-insulating box 5 to the first heat-insulating box 1 through the second thread 10 and the fourth thread 16.
[0042] Among them, by placing dry ice inside the second thermal insulation box 5, the dry ice sublimates and absorbs the heat inside the first thermal insulation box 1, so that the temperature inside the first thermal insulation box 1 is reduced, thereby achieving the effect of refrigerating the microorganisms inside the sampling tube 6;
[0043] Wherein, by providing the connecting pipe 11 and the micro pressure relief pump 12 , when the carbon dioxide pressure inside the first thermal insulation box 1 is too high, the micro pressure relief pump 12 will automatically open to automatically relieve the pressure inside the first thermal insulation box 1 .
[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
