Description

Technical Field

[0001] This utility model relates to the field of biological detection technology, specifically a sampler for biological detection. Background Technology

[0002] Bioassay is a technology that measures biological, chemical, and physical indicators inside and outside an organism to detect aspects such as the organism's health status, environmental quality, and food safety.

[0003] The origins of biological samplers can be traced back to the early 20th century, when scientists began using various tools and techniques to collect biological samples for laboratory analysis and research. These early samplers were typically simple tools, such as syringes, pipettes, and blood collection tubes, used to collect biological samples such as blood, tissues, and cells.

[0004] With the development of science and technology, the types and functions of biological detection samplers are constantly increasing. For example, there are now samplers specifically designed for collecting different types of biological samples, such as microorganisms, plants, and animals. These samplers have different designs and working principles to adapt to different sampling needs. However, during sampling, if the sample volume is insufficient, it may be impossible to perform all the necessary tests; while an excessive sample volume may lead to waste, and in some cases, an excessive sample volume may affect the accuracy of the test results. Therefore, those skilled in the art provide a biological detection sampler to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a sampler for biological detection to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A biological detection sampler includes a sampler, a sampler base, a primary sampling circulation pump, electronic components, a positioning seat, a controller, and a secondary sampling pump. The sampler base is movably connected to the lower part of the inner wall surface of the sampler at an engagement point. The top periphery of the sampler base is fixedly connected to an installation thread. A sampling tube is movably connected to the left end of the top of the sampler base through a through-hole. A primary sampling tube is movably connected to the upper right end of the sampling tube through a through-hole. The other end of the primary sampling tube is movably connected to the primary sampling circulation pump. A primary discharge tube is movably connected to the upper right end of the primary sampling circulation pump through a through-hole. The other end of the primary discharge tube is movably connected to a sample storage container at the right end of the top of the sampler base. Electronic components are movably connected to the upper left end of the sample storage container through a through-hole. A water level detection element is movably connected to the right end of the electronic components.

[0008] Preferably, a positioning seat is movably connected to the lower side of the outer wall surface of the sampler, and spring rods are fixedly connected to the top of the left and right sides inside the positioning seat.

[0009] Preferably, the outer wall surface of the spring rod is surrounded by a spring, and the outer wall surface of the spring rod is slidably connected to the telescopic contact rod.

[0010] Preferably, handles are fixedly connected to the upper sides of both ends of the sampler, and a controller is movably connected to the upper right side of the sampler's interior top.

[0011] Preferably, the sampler has a sampling display screen on the top left side and several control buttons on the top right side.

[0012] Preferably, the upper right side of the sample storage container is movably connected to the upper right side of the sampler via a second sampling tube, and the end of the second sampling tube is movably connected to a second sampling pump.

[0013] Preferably, the outer wall surface of the second sampling pump is movably connected to the second sampling pump fixing component, and the bottom middle of the second sampling pump is movably connected to the second sample outlet tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Press down the sampler so that the pointed end of the sampling tube passes through the object's surface. The operator can then start the No. 1 sampling circulation pump via the control button. Under its suction, the biological sample is drawn from the sampling tube into the No. 1 sampling tube. The No. 1 sampling circulation pump can control the sample extraction speed and flow rate to ensure that the sample is extracted according to the predetermined requirements. The extraction volume can also be adjusted according to different testing needs. The biological sample extracted by the No. 1 sampling circulation pump flows into the sample storage container through the No. 1 sample outlet tube. The sample storage container is used to store the collected biological sample. Its material and design may have functions to prevent sample deterioration and leakage, ensuring the integrity of the sample before testing. Electronic components and water level detection components play a role in the sampler. The water level detection element plays a role in control and monitoring. It detects the sample liquid level in the sample storage vessel and transmits the liquid level information to the controller. The controller processes the information and presents it digitally on the display screen. This ensures the accuracy of the sampling process. The stable connection between the sampler and the base, the precise control of the sampling speed and flow rate by the sampling pump, and the accurate sample transfer through the sample outlet tube all contribute to obtaining accurate biological samples and improving the accuracy of biological detection. The reasonable design of the sample storage vessel and the precise control of the entire sampling and transfer process help maintain the integrity of the biological samples and avoid contamination and deterioration during the collection, transfer, and storage process, thus providing a reliable sample basis for subsequent biological detection.

[0016] 2. Place the telescopic contact rod on the surface of the object. The telescopic contact rod may come into contact with different surfaces or objects. The elastic force of the spring can allow the telescopic contact rod to adapt to different contact conditions and maintain a stable contact pressure, thereby ensuring the accuracy and reliability of sampling. The stable support of the positioning seat and the elastic adaptability of the telescopic contact rod help to improve the sampling accuracy of the sampler in different environments and conditions.

A water level detection element 10 is movably connected to the right end of the electronic component 9. A positioning seat 11 is movably connected to the lower side of the outer wall surface of the sampler 1. Spring rods 12 are fixedly connected to the top of the left and right sides inside the positioning seat 11. A spring 13 is wrapped around the outer wall surface of the spring rod 12. A telescopic contact rod 14 is slidably connected to the outer wall surface of the spring rod 12. Handles 15 are fixedly connected to the upper left and right ends of the sampler 1.

[0023] The working principle of this utility model is as follows: When using this utility model, firstly, the operator holds the handle 15 and lifts the sampler 1 to the object where a sample needs to be taken. After selecting a suitable sampling position, the sampler 1 is used for sampling. The telescopic contact rod 14 is placed on the surface of the object. The telescopic contact rod 14 may come into contact with different surfaces or objects. The elastic force of the spring 13 allows the telescopic contact rod 14 to adapt to different contact conditions, maintaining a stable contact pressure, thereby ensuring the accuracy and reliability of the sampling. The sampler 1 is then pressed down, causing the pointed end of the sampling tube 4 to pass through the surface of the object. The operator can then start the first sampling circulation pump 6 via the control button 17. Under its suction, the biological sample is drawn from the sampling tube 4 into the first sampling tube 5. The first sampling circulation pump 6 can control the sampling speed and flow rate, ensuring that the sample is extracted according to the predetermined requirements. The amount extracted can also be adjusted according to different testing needs. The biological sample extracted by the first sampling circulation pump 6 flows into the sample storage container 8 through the first sample outlet tube 7. The sample storage container 8 is used to store the collected biological samples. Its material and design may have functions such as preventing sample deterioration and leakage to ensure the integrity of the sample before testing. Electronic components 9 and 10 play a control and monitoring role in the sampler 1. The water level detection element 10 is used to detect the sample liquid level in the sample storage container 8 and transmit the liquid level information to the controller 18. The controller 18 processes the information and presents it digitally on the display screen 16. The operator extracts samples as needed. When a sample is needed, the operator can start the second sampling pump 20 through the control button 17. Under the suction of the second sampling pump 20, the biological sample is sucked from the sample storage container 8 into the second sampling tube 19. The second sampling pump 20 can also control the sample extraction speed and flow rate to ensure that the sample is extracted according to the predetermined requirements. The amount extracted can also be adjusted according to different testing needs. The biological sample extracted by the second sampling pump 20 can be introduced into the biological detector through the second sample outlet tube 22.
