[0032] In order to keep the following description of the embodiments of the present utility model clear and concise, the detailed description of known functions and known components is omitted in the present utility model.
[0033] Embodiment 1
[0034] Please refer to Figures 1-5 As shown, in this embodiment, a sampling device is provided, including: a driving part 1 and a collecting part 2.
[0035] The driving part 1 is composed of a push-pull cylinder 3 and a push-pull rod 5. The push-pull rod 5 is arranged inside the push-pull cylinder 3, and one end of it slides through one end of the push-pull cylinder 3 to achieve telescopic movement; the collection part 2 includes a sampling cylinder 4 and a sampling swab 6. The sampling swab 6 is located inside the sampling cylinder 4 and is used to collect mycobacterium samples; the push-pull rod 5 controls the sampling swab 6 to move back and forth in the sampling cylinder 4 through a specific pushing component to complete the sampling operation.
[0036] To push the push-pull rod 5 to extend and retract and ensure its stability, a pushing component is designed in this embodiment; this component includes a limit slider 9 fixedly installed at one end of the push-pull rod 5. The limit slider 9 is slidably connected to the inner wall of the push-pull cylinder 3 to prevent the push-pull rod 5 from deflecting during movement. Three limit ridges 10 are also fixedly installed on the outer wall of the push-pull rod 5 and cooperate with two limit collar rings 14 inside the push-pull cylinder 3 to further limit the rotation of the push-pull rod 5; in addition, a chute 7 is provided on the outer wall of the push-pull cylinder 3. A fixing rod 8 on the push-pull rod 5 passes through the chute 7 and is slidably connected to it. By operating the fixing rod 8, the push-pull movement of the push-pull rod 5 can be realized.
[0037] To fix the push-pull rod 5 at a specific position, the pushing component also includes a plurality of positioning grooves 11 provided on the outer wall of the push-pull rod 5, three first elastic pieces 15 and first clamping columns 16 inside the push-pull cylinder 3. The plurality of positioning grooves 11 are divided into three groups and cooperate with the corresponding first elastic pieces 15 and first clamping columns 16; when the push-pull rod 5 moves, the first elastic piece 15 will drive the first clamping column 16 to snap into the corresponding positioning groove 11, thereby realizing the positioning of the push-pull rod 5; this positioning effect can ensure that the push-pull rod 5 will not move due to the action of gravity when it is stationary. When the user needs to move the push-pull rod 5, pushing and pulling the push-pull rod 5 forcefully can make it move normally.
[0038] Furthermore, a connecting component is also provided in this embodiment to realize the connection between the driving part 1 and the collection part 2; the connecting component mainly includes components such as a sealing slider 21, a connecting sleeve 22, a connecting head 12 and a second elastic piece 17; the sealing slider 21 is hermetically and slidably arranged inside the sampling cylinder 4 and is fixedly connected to one end of the sampling swab 6. The connecting sleeve 22 is fixedly installed on one side of the sealing slider 21 and is provided with a clamping hole 23. The extending end of the push-pull rod 5 is provided with a connecting head 12. A second elastic piece 17 is placed inside the connecting head 12, and a second clamping column 18 is fixed on one side of the second elastic piece 17; when the connecting head 12 is docked with the connecting sleeve 22, the second clamping column 18 is snapped into the clamping hole 23 under the action of the second elastic piece 17, realizing the connection between the push-pull rod 5 and the sampling swab 6, thereby driving the sampling swab 6 to perform sampling.
[0039] To further drive the sampling swab head 6, in this embodiment, a connecting pipe 19 is fixedly installed at one end of the push-pull cylinder 3, and a first snap ring 20 is provided on the outer wall of the connecting pipe 19; a second snap ring 24 that cooperates with the first snap ring 20 is provided on the inner wall of the sampling cylinder 4. The connection between the sampling cylinder 4 and the push-pull cylinder 3 is achieved through the engagement of the two, so as to realize the pushing out and retracting of the sampling swab head 6.
[0040] This application can be used in the technical field of medical sampling equipment, and can also be used in other fields applicable to this application.
[0041] Embodiment 2
[0042] Reference Figure 2 、 5 On the basis of Embodiment 1, an improvement is made: a sampling device for mycobacterium detection, which is applied to the technical field of medical sampling equipment;
[0043] In addition, a end cap 26 is provided at the end of the sampling cylinder 4 away from the push-pull cylinder 3 for closing the sampling cylinder 4; a third snap ring 25 is fixedly installed at one end of the inner wall of the sampling cylinder 4, and the end cap 26 is snap-fitted to the inner wall of the sampling cylinder 4 through the third snap ring 25; two grooves are also provided on the outer wall of the end cap 26 to facilitate disassembly operation.
[0044] The second snap ring 24 and the third snap ring 25 can also cooperate with the sealing slider 21 to limit the movement of the sealing slider 21, prevent the sealing slider 21 from falling off, and ensure good driving and sealed storage effects for the sampling swab head 6.
[0045] The usage process and working principle of the technical solution of this utility model are as follows:
[0046] When in use, the user can install the collection part 2 to be used at one end of the driving part 1. During installation, the user needs to stand up the sampling tube 4, remove the end cover 26, and then move the sealing slider 21 to one end of the sampling tube 4 under the action of gravity. The second clamping ring 24 can limit the movement of the sealing slider 21 to prevent the sealing slider 21 from falling off; then the user needs to insert the connecting head 12 into the connecting sleeve 22, so that the second clamping column 18 is clamped into the clamping hole 23 under the action of the second elastic sheet 17, and then the sampling tube 4 can be pushed close to the connecting head 12. The pipe 19 is connected to the push-pull tube 3 and the sampling tube 4 by squeezing and engaging the first clamping ring 20 and the second clamping ring 24. Then, the sampling swab head 6 is pushed out by the push-pull rod 5 to start sampling mycobacteria. When the user uses it, the push-pull rod 5 can be pushed out by pushing the fixing rod 8. When the push-pull rod 5 is pushed out, the three first elastic sheets 15 inside the push-pull tube 3 will drive the first clamping column 16 to continuously cling to the outer wall of the push-pull rod 5, and as the push-pull rod 5 moves, the three first clamping columns 16 will continuously align with the multiple positioning grooves 11. The push-pull rod 5 can be locked to fix it at multiple positions, so that it is convenient for users to push out and use sampling swab heads 6 of various specifications. When the user needs to continue to adjust the position of the push-pull rod 5, he only needs to push the fixing rod 8 with force; when the user uses the sampling swab head 6 to complete the sampling, the fixing rod 8 can be pushed in the reverse direction to complete the retraction of the push-pull rod 5. At this time, the sampling swab head 6 will also be retracted into the sampling tube 4, thereby completing the collection and preservation of the sampled sample; then the user can reverse the above operation, disassemble the sampling tube 4 and pull it for a distance, and after the connecting sleeve 22 is exposed, the second clamping column 18 can be pressed to complete the disassembly of the connecting sleeve 22, and then the driving part 1 and the collecting part 2 can be separated again, and the user can then cover the end cover 26 again to complete the sealing of the inside of the sampling tube 4, which can ensure the good preservation and transportation effect of the mycobacterium sampling sample; then the user can replace other collecting parts 2 for continuous detection; subsequently, it is only necessary to transport the multiple collecting parts 2 with the sampled samples to the detection area, and take out the internal sampling swab heads 6 for sample removal and detection.
[0047] It should be noted that, in the description of this specification, descriptions such as "first", "second", etc. are merely used to distinguish between various features and have no actual order or directional meaning, and this application is not limited to this.
