Description
Technical Field
[0001] This utility model relates to the technical field of biological experiments, and in particular to a sampling bag for biological experiments that can be quickly sealed. Background Technology
[0002] Biological experiments are an important part of scientific research, involving multiple aspects such as the collection, preservation, and analysis of biological samples. In this process, sampling bags, as temporary storage containers for biological samples, play a crucial protective role. They not only prevent samples from being contaminated by the external environment, but also effectively prevent leakage or deterioration of samples during collection and transportation.
[0003] When it is necessary to seal the sampling bags, traditional methods such as tying with ropes or clips are simple and convenient, but they cannot guarantee a tight seal. This can lead to sample leakage or contamination during the preservation and transportation of biological samples, thus affecting the accuracy of experimental results. Therefore, most people use heat sealing or adhesive sealing methods. However, these methods require additional tools or equipment, and are difficult to reopen after sealing. The operation is cumbersome, and improper operation may damage the sampling bag or the sample, causing inconvenience to biological experiments. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, this utility model provides a sampling bag for biological experiments that can be quickly sealed. Through the setting of the sealing mechanism, the sampling bag can be sealed quickly and reliably. Moving the lever moves the squeezing block and presses the bag opening into the slot. With the help of the sealing strip, the sealing performance is enhanced, preventing sample leakage and contamination. Moving the lever in the opposite direction can easily open the sampling bag. The operation is simple and quick, ensuring the safety and stability of biological samples during collection, transportation and storage.
[0006] To achieve the above objectives, the first aspect of this utility model provides a sampling bag for biological experiments that can be quickly sealed, comprising: a sampling bag and a sealing mechanism. The sealing mechanism is disposed on the outer wall of the sampling bag and includes a sealing strip, a squeezing block and a pushing block. The sealing strip is disposed on the outer wall of the sampling bag, and a groove is formed on the outer wall of the sealing strip. The squeezing block is disposed on the inner wall of the groove, and the pushing block is disposed on the outer wall of the squeezing block. A slot is formed on the inner wall of the sealing strip.
[0007] In addition, the biological experimental sampling bag that can be quickly sealed according to the present invention may also have the following additional technical features:
[0008] Specifically, an exhaust assembly is provided on the outer wall of the sampling bag. The exhaust assembly includes an exhaust pipe, a limiting plate, a spring, and a sealing plate. One end of the exhaust pipe is connected to the sampling bag, the limiting plate is set on the inner wall of the exhaust pipe, the spring is set inside the exhaust pipe, and one end of the spring is connected to the limiting plate. The sealing plate is connected to the other end of the spring.

Detailed Implementation
[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0022] The following describes an embodiment of the present invention with reference to the accompanying drawings: a sampling bag for biological experiments that can be quickly sealed.
[0023] like Figures 1-4 As shown in the figure, a biological experimental sampling bag that can be quickly sealed according to an embodiment of the present invention includes: a sampling bag 1 and a sealing mechanism 2.
[0024] The sealing mechanism 2 is installed on the outer wall of the sampling bag 1. The sealing mechanism 2 includes a sealing strip 21, a squeezing block 23, and a pushing block 24.
[0025] A sealing strip 21 is set on the outer wall of the sampling bag 1. A groove 22 is provided on the outer wall of the sealing strip 21. A squeezing block 23 is set on the inner wall of the groove 22. A pusher block 24 is set on the outer wall of the squeezing block 23. A slot 26 is provided on the inner wall of the sealing strip 21.
[0026] Specifically, when it is necessary to seal the sampling bag 1, the pressing block 23 is moved within the slide groove 22 by first moving the toggle block 24, thereby pressing the opening of the sampling bag 1 into the slot 26. During the sealing process, simply moving the toggle block 24 from the initial end to the other end of the slot 26 completes the compression and fixation of the opening of the sampling bag 1. The sealing strip 27 provided on the inner wall of the slot 26 effectively enhances the sealing performance, preventing leakage of biological samples inside the sampling bag 1 or external contamination.
[0027] When it is necessary to open the sampling bag 1, simply reverse the lever 24 to make the squeezing block 23 move in the opposite direction within the slide groove 22, thereby releasing the squeezing of the opening of the sampling bag 1 and making it easy to open the sampling bag 1. This method is not only simple and quick to operate, but also has a reliable sealing effect, which can effectively ensure the safety and stability of biological samples during collection, transportation and storage.
[0028] In one embodiment of this application, such as Figure 4As shown, an exhaust assembly 3 is provided on the outer wall of the sampling bag 1.
[0029] The exhaust assembly 3 includes an exhaust pipe 31, a limiting plate 32, a spring 33, and a sealing plate 34.
[0030] One end of the exhaust pipe 31 is connected to the sampling bag 1. The limiting plate 32 is set on the inner wall of the exhaust pipe 31. The spring 33 is set inside the exhaust pipe 31, and one end of the spring 33 is connected to the limiting plate 32. The sealing plate 34 is connected to the other end of the spring 33.
[0031] Specifically, when venting is required inside the sampling bag 1, simply squeeze the sampling bag 1 to push the sealing plate 34 with the internal gas. The sealing plate 34 compresses the spring 33. At this time, the exhaust pipe 31 is connected to the inside of the sampling bag 1, and the gas is discharged through the exhaust pipe 31. After venting is completed, the elasticity of the spring 33 causes the sealing plate 34 to reset and re-seal the exhaust pipe 31, preventing outside air from entering the sampling bag 1. This achieves the functions of venting and automatic sealing of the sampling bag 1, effectively avoiding the risk of biological sample contamination that may occur when venting by opening the bag opening of the sampling bag 1, and ensuring the purity of the biological sample during sampling and subsequent processing.
[0032] In one embodiment of this application, such as Figure 3 As shown, a first anti-slip groove 25 is provided on the outer wall of the lever 24, and a sealing strip 27 is provided on the inner wall of the slot 26.
[0033] Understandably, the first anti-slip groove 25 greatly increases the friction of the outer wall of the lever 24. When the operator needs to move the lever 24 to seal or open the sampling bag 1, even if the hands are wearing gloves, it is not easy to slip, thus ensuring the accuracy and convenience of the operation. The sealing strip 27 is made of a soft and elastic material and fits tightly against the inner wall of the slot 26. When the squeezing block 23 presses the opening of the sampling bag 1 into the slot 26, the sealing strip 27 is squeezed and deformed, thus making close contact with the opening of the sampling bag 1, thereby achieving a sealing effect and further preventing biological samples from leaking or being contaminated by the outside world, ensuring the accuracy and reliability of biological experiments.
[0034] In one embodiment of this application, such as Figure 4 As shown, a sealing cap 4 is provided on the outer wall of the exhaust pipe 31, and the exhaust pipe 31 and the sealing cap 4 are connected by threads.
[0035] Understandably, the sealing cap 4 can further enhance the sealing performance of the exhaust pipe 31. When exhaust operation is not required, the sealing cap 4 can be tightly screwed onto the exhaust pipe 31 through the threaded connection, which can effectively prevent external air, moisture or other impurities from entering the exhaust pipe 31 and causing pollution to the exhaust pipe 31.
[0036] In one embodiment of this application, such as Figure 4 As shown, a second anti-slip groove 5 is provided on the outer wall of the sealing cover 4, and a guide rod 35 is provided on the outer wall of the sealing plate 34.
[0037] Understandably, the second anti-slip groove 5 further increases the friction coefficient of the outer wall of the sealing cap 4. This ensures that when operators rotate the sealing cap 4 to tighten or loosen it, even if their hands are wet or they are wearing gloves, they can maintain sufficient grip and prevent operational errors caused by slipping. This ensures that the sealing effect of the exhaust assembly 3 is not affected. At the same time, when the sealing cap 4 is connected to the exhaust pipe 31 by threads, the sealing cap 4 will press against the guide rod 35, preventing the sealing plate 34 from moving. This ensures that the exhaust pipe 31 is always in a reliable sealing state when not venting, providing more stable protection for the biological samples in the sampling bag 1.
[0038] In one embodiment of this application, such as Figure 2 As shown, a hanging strap 6 is provided on the outer wall of the sampling bag 1.
[0039] Understandably, the design of the strap 6 greatly facilitates the carrying and storage of the sampling bag 1. During biological experiments, researchers often need to carry multiple sampling bags 1 and other experimental equipment at the same time. The design of the strap 6 allows the sampling bag 1 to be easily hung on the experimental cart, hook, or on the researcher's waist, which not only saves space but also avoids the risk of contamination that may be caused by placing the sampling bag 1 randomly.
[0040] Working principle: When sealing the sampling bag 1 is required, the pressing block 23 is moved within the slide groove 22 by moving the toggle block 24, thereby pressing the opening of the sampling bag 1 into the slot 26. During the sealing process, simply moving the toggle block 24 from the initial end to the other end of the slot 26 completes the compression and fixation of the opening of the sampling bag 1. The sealing strip 27 on the inner wall of the slot 26 effectively enhances the sealing performance, preventing leakage of biological samples from the sampling bag 1 or contamination from the outside environment.
[0041] When it is necessary to open the sampling bag 1, simply reverse the lever 24 to move the squeezing block 23 in the reverse direction within the slide groove 22, releasing the squeezing of the sampling bag 1 opening, and the sampling bag 1 can be easily opened. This is not only simple and quick to operate, but also has a reliable sealing effect, effectively ensuring the safety and stability of biological samples during collection, transportation, and storage. At the same time, through the setting of the exhaust component 3, when it is necessary to exhaust the sampling bag 1, simply squeeze the sampling bag 1 to make the internal gas push the sealing plate 34, and the sealing plate 34 compresses the spring 33. At this time, the exhaust pipe 31 is connected to the inside of the sampling bag 1, and the gas is discharged through the exhaust pipe 31. After the exhaust is completed, the elasticity of the spring 33 causes the sealing plate 34 to reset, re-sealing the exhaust pipe 31 to prevent outside air from entering the sampling bag 1. This realizes the exhaust and automatic sealing functions of the sampling bag 1, effectively avoiding the risk of biological sample contamination that may occur when the sampling bag 1 opening is opened for exhaust operation, and ensuring the purity of biological samples during sampling and subsequent processing.
[0042] In summary, this utility model provides a biological experimental sampling bag that can be quickly sealed. Through the sealing mechanism 2, the sampling bag 1 can be sealed quickly and reliably. Moving the lever 24 moves the squeezing block 23, pressing the bag opening into the slot 26. The sealing strip 27 enhances the sealing performance, preventing sample leakage and contamination. Moving the lever 24 in the opposite direction can easily open the sampling bag 1. The operation is simple and quick, ensuring the safety and stability of biological samples during collection, transportation and storage.
