Description

Technical Field

[0001] The utility model belongs to the technical field of field biological sample collection tools. More specifically, the utility model relates to a sampling bag for field biological sample collection. Background Technique

[0002] For the collection of field biological samples (such as samples of animal and plant molecular genetic materials DNA, RNA, etc.), it is necessary to instantaneously freeze the samples to maintain their biological activity and keep them in an ultra-low temperature state (about -80°C). At present, liquid nitrogen is mainly used in laboratories and experimental bases to quickly freeze samples. However, since this traditional quick-freezing material, liquid nitrogen, is a high-pressure liquid, it requires a special device with strong pressure resistance - such as a liquid nitrogen tank - to hold it. This device is not suitable for field collection and carrying. Especially when entering deep mountains or the hinterland of forests far from transportation, the shape of the liquid nitrogen tank is too bulky to be carried around. Moreover, the tank body is made of metal material, which is more than a dozen times heavier than the contents inside, and is very unsuitable for field collection of ultra-low temperature materials. There is an urgent need for a portable and well-insulated ultra-low temperature preservation tool.

[0003] In response to this, the prior art discloses a field low-temperature sampling bag (publication number: CN206208561U) to solve the problem of inconvenient carrying. It realizes comfortable walking with a backpack by having a sampling box inside the backpack body. However, during the field collection process, it is possible to collect hundreds of samples in a day. When putting samples into the existing sampling bag, it is necessary to first unzip the sampling bag, then open the lid of the sampling box, and then close it in reverse order. The operation is troublesome, and the cold air is likely to escape, affecting the low-temperature preservation effect and it is not convenient for classification. There is an urgent need for improvement. Summary of the Utility Model

[0029] Figures 1 to 3 The implementation form of a sampling bag for field biological sample collection is shown, which includes a shaped heat preservation double-shoulder backpack body. The shaped heat preservation double-shoulder backpack body can be selected from existing shaped heat preservation double-shoulder backpack bodies. A sample placement opening is penetrated through the top cover 10 of the main bag 5 of the backpack body, and a heat preservation cover plate 2 capable of opening and closing the sample placement opening by turning up and down is arranged on the sample placement opening. The inner side surface of the heat preservation cover plate 2 is adhesively connected to the circumferential direction of the sample placement opening through a first connecting piece 11 to achieve opening and closing; the first connecting piece 11 is a magic tape that is circumferentially arranged on the inner side surface of the heat preservation cover plate 2 and the circumferential direction of the sample placement opening and is mutually matched and adhered, or a magnet that can be mutually matched and adsorbed.

[0030] In the above technical solution, the shaped heat-insulating double-shoulder backpack body of the sampling bag for collecting wild biological samples of the present utility model can be shaped into a required shape, such as a similar cylindrical shape, a round-edge square shape, etc. The upper end of the main bag 5 of the backpack body is open, and the top cover 10 is connected to the upper port of the main bag 5 through a loop buckle zipper 4, so as to form a heat-insulating space inside the main bag 5. The wall body of the backpack body is filled with a heat-insulating layer, and the heat-insulating cover plate is also filled with a heat-insulating layer, having a good heat-insulating effect. The back surface 9 of the backpack body has a decompression pad body matching the human back, which can increase the comfort. The back surface 9 of the backpack body is provided with double-shoulder straps 1 for easy carrying and walking, leaving both hands free to collect samples. A sample placing opening penetrates through the top cover 10 of the main bag 5 of the backpack body. The size of the sample placing opening is set to be less than 1 / 5 of the size of the top cover 10 and greater than 3 times the diameter of the cryogenic tube for placing samples, facilitating the cryogenic tube to be put into the main bag 5 through the sample placing opening. A heat-insulating cover plate 2 capable of opening and closing the sample placing opening by turning up and down is arranged on the sample placing opening. The inner side circumference of the heat-insulating cover plate 2 and the circumference of the sample placing opening are adhered through a first connecting member 11 to realize opening and closing; the first connecting member 11 is a magic tape provided on the inner side circumference of the heat-insulating cover plate 2 and the circumference of the sample placing opening and matching and fitting with each other, or a magnet capable of mutually attracting and matching, so that the sample placing opening and the heat-insulating cover plate 2 are convenient to open and close.

[0031] When the present utility model is in use, open the top cover 10 of the main bag 5 of the backpack body, and put a refrigerating object into the main bag 5 of the backpack body. The refrigerating object is, for example, dry ice, a chemical ice pack, etc. Then quickly close the top cover 10 of the backpack body through the loop buckle zipper 4, and the sample placing opening of the top cover 10 is closed through the heat-insulating cover plate 2, so that the heat-insulating space formed inside the main bag 5 of the backpack body maintains a low temperature state. When a sample is collected, take out consumables (such as tin foil, cryogenic tube) from the secondary bag 7, wrap the sample with tin foil, put it into the cryogenic tube and tighten the lid, then turn up the heat-insulating cover plate 2 upward through the handle 3 to open the sample placing opening, put the cryogenic tube containing the sample into the main bag 5, and then quickly release the heat-insulating cover plate 2 or turn it downwards by following the trend to press the heat-insulating cover plate 2, and the sample placing opening can be closed. The operation is convenient and can reduce the cold air emission.

[0032] On the basis of the above implementation manner, a handle 3 is arranged on the heat-insulating cover plate 2.
