The second fixing sleeve 122 may have a second mating portion F2. The second fixing sleeve 122 and the first inner sleeve 131a are sleeved with each other. The cooperation of the first mating portion F1 and the second mating portion F2 limits translation of the first fixed sleeve 121 relative to the first inner sleeve 131a on the axis a. In addition, the second fixing sleeve 122 and the first inner sleeve 131a are slightly interference fit (i.e., a tight fit) with each other in structure to detachably connect the first cover 131 with the filter holder 120.
Referring to fig. 1A and 1B, in the present embodiment, the first fixing sleeve 121 may have a first engaging portion E1 (e.g. an annular groove). The second fixing sleeve 122 may have a second engaging portion E2 (e.g. an annular rib). The engagement of the first engagement portion E1 and the second engagement portion E2 restricts translation of the second fixing sleeve 122 relative to the first fixing sleeve 121 on the axis a, as shown in fig. 3. Accordingly, the second fixing sleeve 122 is detachably fixed to the first fixing sleeve 121 by the fitting between the first fitting portion E1 and the second fitting portion E2.
Referring to fig. 1A, 1B and 3, in the present embodiment, the first fixing sleeve 121 has one or more first guiding portions G1 (e.g. guiding ribs). The second fixing sleeve 122 may have one or more second guide portions G2 (e.g., guide grooves). The cooperation of the first guide G1 and the second guide G2 limits the rotation of the second fixing sleeve 122 relative to the first fixing sleeve 121 on the axis a. Accordingly, the second fixing sleeve 122 is detachably fixed to the first fixing sleeve 121 by the fitting between the first fitting portion E1 and the second fitting portion E2.
Referring to fig. 1A, 1B and 3, in the present embodiment, the second cover 132 has a second inner sleeve 132a. First fixation sleeve 121 and second inner sleeve 132a nest with one another to position filter holder 120 within second cover 132.
Referring to fig. 1A, 1B and 3, in the present embodiment, the first cover 131 has a first thread S1 (e.g. an internal thread). The second cover 132 has a second thread S2, and engagement of the first thread S1 with the second thread S2 connects the first cover 131 to the second cover 132.
Referring to fig. 1A, fig. 1B, and fig. 3, in the present embodiment, the virus collection assembly 100 further includes a sealing rubber ring 133, the first cover 131 is connected to the second cover 132, and the sealing rubber ring 133 is located between the first cover 131 and the second cover 132.
Referring to fig. 1A, 1B and 3, in the present embodiment, the filter holder 120, the first cover 131 and the second cover 132 may form a virus storage device 100a. In addition, the virus storage device 100a may also include other components, such as the sealing rubber ring 133 described above. In other words, the virus collection assembly 100 includes a blowing nozzle 110 and a virus storage device 100a.
A virus collection method according to an embodiment of the present invention is described below with reference to fig. 2A to 2K, and the components used in the virus collection assembly 100 shown in fig. 1A and 1B may be found. The virus collection method comprises the following steps.
Referring to FIG. 2A, one end of the nozzle 110 may be closed by a seal cap 70. In other embodiments, the seal cap 70 may be absent.
Referring to fig. 2B, after the sealing cap 70 is removed from the blowing nozzle 110, the blown gas from the subject is received through the blowing nozzle 110 to the gas collecting bag 50 communicating with the blowing nozzle 110.
Referring to fig. 2C, after the gas collecting bag 50 collects the gas blown out by the subject, a filter holder 120 is mounted to the blowing nozzle 110. Specifically, as shown in FIG. 2C, filter holder 120 may be removably coupled to first cover 131. Next, as shown in fig. 2D, filter holder 120 is detachably connected to blowing nozzle 110 via first cover 131. Thereafter, as shown in FIG. 2E, first cover 131 is detached from filter holder 120.
Referring to FIG. 2F, the gas collected in the gas collection bag 50 is pumped (e.g., by a pump) through the gas nozzle 110 such that the gas collected in the gas collection bag 50 flows through a filter 60 secured by the filter holder 120, as shown in FIG. 1A. Thus, microorganisms such as viruses in the gas flowing through filter 60 will remain on filter 60.
In this embodiment, filter 60 may be clamped via first and second fixation sleeves 121 and 122 of filter holder 120. In addition, filter 60 may be pre-attached to one end of second stationary sleeve 122 by a double sided film 62. Thus, double-sided film 62 ensures that filter 60 does not deviate in position during the process of first and second fixing sleeves 121 and 122 being nested with each other.
Referring to FIG. 2G, a first cover 131 is detachably coupled to filter holder 120. Specifically, as shown in FIG. 2G, first cover 131 and filter holder 120 are mated with each other on axis A. Next, as shown in fig. 2H, first cover 131 is rotated a specific angle with respect to air tap 110 to release the removable connection (e.g., the engagement between first latch L1 and second latch L2) between filter holder 120 and air tap 110. In this embodiment, first cover 131 and filter holder 120 are a slightly interference fit, i.e., a tight fit, in structure with each other. Thus, when filter holder 120 is not removably coupled to blowing nozzle 110, removing first cover 131 from blowing nozzle 110 may be associated with removing filter holder 120 from blowing nozzle 110.
Referring to FIG. 2I, after first cover 131 is detachably coupled to filter holder 120, filter holder 120 and its attached filter 60 are detached from blowing head 110 via first cover 131.
Referring to fig. 2J, the first cover 131 is connected to a second cover 132, such that the filter holder 120 and the filter 60 held thereby are accommodated in the first cover 131 and the second cover 132. Specifically, as shown in FIG. 2J, first cover 131 with filter holder 120 thereon may be moved toward second cover 132. Next, as shown in fig. 2K, the first cover 131 is detachably connected to the second cover 132 via engagement of the first screw S1 of the first cover 131 and the second screw S2 of the second cover 132.
In summary, in the present invention, the gas possibly containing the microorganism sample such as virus from the subject is collected by blowing, and the microorganism sample such as virus possibly existing in the gas is retained in the filter by sucking air. In addition, the filter disc fixer and the filter disc clamped by the same are taken out through the first cover body, and the filter disc fixer and the filter disc clamped by the same are stored through the first cover body and the second cover body which are assembled together, so that the subsequent preservation, transportation and testing operation of microorganism samples such as viruses and the like are facilitated.
