Examples
As shown in fig. 1, this embodiment provides a disposable sterile sampler, and the outside of the sampler is provided with a sleeve 1, which can provide protection for the sterile environment of the sampling head 7 before and after sampling, and prevent the sampling head 7 from being polluted by pollutants in other environments.
Different from the prior art, the sampling tube 2 of the sampler is arranged in the sleeve 1, the outer side of the sampling tube 2 is provided with the movable plate 5 which can rotate around the axial direction, the sampling tube 2 is fixed on the movable plate 5, the movable plate 5 and the push rod 3 are of an integrated structure, and the bottom of the push rod 3 is provided with a T-shaped grab handle 4 which is convenient to push and rotate. Thus, the sampler of the present utility model is able to control the forward, backward and rotational movement of the sampling tube 2 within the sleeve 1 by means of the grip 4 outside the sleeve 1.
The fixed plate 6 is arranged on the outer side of the movable plate 5, a gap exists between the fixed plate 6 and the movable plate 5, and limiting components are arranged at the upper end and the lower end of the fixed plate 6 on the inner wall of the sleeve 1, and limit components limit the fixed plate 6 to move forwards or backwards only and cannot be driven to rotate by the movable plate 5. The clearance between fixed plate 6 and fly leaf 5 makes fly leaf 5 can not touch fixed plate 6 in the pivoted, avoids the friction, makes push rod 3 operation simpler and more convenient.
The sampling head 7 of the sampler is arranged on the base 8, and the width of the base 8 is larger than that of the sampling head 7. The bottom of the base 8 is a cylinder, a thread structure is arranged on the bottom, and matched threaded holes are formed in the top of the sampling tube 2, so that the sampling head 7 can be fixed on the sampling tube 2, and a waterproof rubber ring is arranged above the threaded holes, so that buffer liquid in the sampling tube 2 is prevented from being spilled.
The middle part of base 8 is polygonal cylinder, is preferably the regular hexahedron that is convenient for process, is equipped with the supporting regular hexagon hole in base 8 middle part on the fixed plate 6, and the fixed plate 6 is smooth with the contact surface of base 8. When the sampling head 7 is required to be stored in the sampling tube 2, the movable plate 5 drives the sampling tube 2 to rotate by rotating the push rod 3, and the base 8 fixed on the sampling tube 2 also has a rotating trend at the moment, but because the middle part of the base 8 is a regular hexahedron and is contacted with the fixed plate 6, the base 8 needs to drive the fixed plate 6 to rotate, and the fixed plate 6 is limited by the limiting component, so that the base 8 cannot be driven to rotate by the movable plate 5, and the sampling tube 2 and the base 8 relatively rotate. Because the contact surface of the thread structure, the fixing plate 6 and the base 8 is smooth and the base 8 is fixed by the fixing plate 6, the movable plate 5 and the sampling tube 2 can move upwards along the base 8 and push the fixing plate 6 upwards, when the sampling tube 2 moves upwards along the threads to the middle of the base 8, the base 8 and the sampling head 7 can fall into the sampling tube 2 through the action of gravity, so that the sampling head 7 can be stored.
The inner wall on the export of sampler sleeve 1 is provided with disposable airtight film 9, and push rod 3 is provided with airtight piston for realize inside sterile environment and the seal of sampler jointly. The sampling head 7 can easily penetrate the airtight film 9 during sampling, and the sampling head 7 can retract into the sleeve 1 to be brought out of the body after sampling, so that pollutants which are stained to other environments are avoided. After the sampling head is taken out of the body, the sampling head 7 falls into the sampling tube 2 by rotating the push rod 3, the movable plate 5 and the sampling tube 2 are pulled out by the push rod 3, the sampling tube 2 is taken down from the movable plate 5 in time, and a cap is covered, so that aseptic pollution-free sampling is realized to the greatest extent.
Finally, it is to be understood that the above embodiments are merely exemplary embodiments employed for the purpose of illustrating the principles of the present utility model, however, the present utility model is not limited thereto.
