Preferably, the pipe diameter of the second pipe member tapers from the first end to the second end.
Preferably, the second pipe fitting is made of flexible materials.
Preferably, the second end edge of the second pipe is rounded.
Preferably, the aperture of the first tube member allows the sampling rod to pass therethrough while the sampling head is not.
Preferably, the storage unit has a cylindrical shape.
Preferably, the pipe diameter of the second pipe fitting is larger than the pipe diameter of the first pipe fitting.
The utility model has at least the following advantages:
1. the sampling swab of the device can hide the sampling head in the second tube when entering and exiting the nasal cavity, so as to prevent the pollution of vestibular skin and nasal hair field planting microorganisms to the sampling head.
2. The center of the two ends of the first pipe fitting is provided with the holes, so that the moving direction of the sampling swab in the pipe cavity is fixed, the pipe wall is prevented from being scratched by the sampling head, the pollution is avoided, and the sample loss is reduced.
Drawings
FIG. 1 is a schematic cross-sectional view of a nasal cavity sampling preservation device of the present utility model;
fig. 2 is a schematic cross-sectional structure of the first tube and the storage part of the present utility model.
Detailed Description
Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a nasal cavity sampling and preserving device. As shown in fig. 1, the nasal cavity sampling and storing device provided in this embodiment includes a sampling unit 10, a storing unit 20, and a sampling swab 30. The sampling swab 30 includes a sampling shaft 31 and a sampling head 32 at the end of the sampling shaft 31, and the sampling swab 30 may be a conventional swab, in this embodiment a cotton swab. The sampling portion 10 includes a first pipe 11 and a second pipe 12. The centers of the two ends of the first pipe fitting 11 are respectively provided with an opening 13. The openings 13 at both ends of the first tube member 11 are only penetrated by the sampling rod 31, and the sampling head 32 is not penetrated. That is, the diameter of the aperture 13 is greater than the diameter of the sampling rod 31 and less than the diameter of the sampling head 32.
The second tube 12 includes a first end 121 and a second end 122. The end of the first pipe 11 is detachably connected to the first end 121 of the second pipe 12, for example, the end of the first pipe 11 is screwed to the first end 121 of the second pipe 12, or the end of the first pipe 11 is clamped to the first end 121 of the second pipe 12. The sampling rod 31 of the sampling swab 30 is movable through the two apertures 13 and has the sampling head 32 located within the second tube member 12. The pipe diameter of the second pipe member 12 is slightly larger than that of the first pipe member 11.
To facilitate insertion of the second tube member 12 into the nasal cavity without injuring the nasal cavity, the tube diameter of the second tube member 12 tapers from the first end 121 to the second end 122; the second pipe fitting 12 is made of flexible materials; the second end 122 of the second tube member 12 is rounded.
The storage part 20 is cylindrical, the storage liquid 21 is contained in the storage part 20, and the end of the storage part 20 can be connected with the end of the first pipe 11 in a matching manner. For example, the end of the holder 20 is identical in structure to the first end 121 of the second tube 12, so that the holder 20 can be connected to the first tube 11 in the same manner as the second tube 12.
The device using method comprises the following steps:
after the second tube 12 of the sampling portion 10 is placed in the anterior nares, it is gently pushed inward about 1 cm to block the nasal hair. Pushing the nasal swab forward to contact the corresponding nasal cavity for sampling, and after the sample is collected, pulling the sampling head 32 back into the second tube 12, and removing the entire device from the nostril.
After the sampling head 32 is pulled up to a position close to the first pipe 11, the first pipe 11 and the second pipe 12 are separated. The sampling swab 30 fitted over the first tube 11 is then connected to the storage unit 20, and the sampling head 32 is immersed in the storage liquid 21 (as shown in fig. 2) to complete the sampling.
After the sampling head 32 is sufficiently immersed, the preservation solution 21 is taken out for detection.
Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
