Detailed Description
The nucleic acid sampling reagent tube according to the present invention will be described in detail below with reference to the drawings.
The reagent vessel cap 20 of the present application comprises an upper cover 22 and a lower cover 21 made of plastic.
The lower cap 21 is formed in a cylindrical shape, and a first female screw is formed on the inner circumference of the lower end thereof to be coupled with a first male screw on the outer circumference of the upper end of the reagent vessel 10; an annular inner edge extending inwards is formed at the upper end of the lower cover 21, and a second internal thread is formed on the inner circumferential surface 23 of the inner edge; the outer peripheral surface of the lower cover 21 is formed as a rough surface; the second side of the outer circumferential surface of the lower cover 21 is formed with a convex tooth 27.
The upper cover 22 is formed in a plate shape; a through hole is formed at the center of the upper cover 22, a third internal thread is formed on the inner circumferential surface of the through hole, a bolt 25 is installed in the through hole, a cylindrical coupling head 24 is formed at the lower end of the bolt 25, and a second external thread corresponding to the second internal thread is formed on the outer circumference of the coupling head 24; a disc-shaped first handle 28 is formed at the upper end of the bolt 25; the first handle 28 is positioned on the upper side of the upper cover 22, and the combining head 24 is positioned on the lower side of the upper cover 22; a recess 2B is formed in the middle of the lower side of the upper cover 22 to receive the coupling head 24; a second end of the outer circumference of the upper cap 22 is formed with a catch 26 corresponding to the teeth 27.
A ring of first rubber ring 2A protruding upward is fixedly formed on the inner edge, and the first rubber ring 2A is used for sealing a gap between the upper cover 22 and the lower cover 21 when the upper cover and the lower cover are combined together.
The top of the upper cover 22 is formed with a ring of second rubber ring 29 projecting upward, the second rubber ring 29 serving to seal a gap between the first handle 28 and the top of the upper cover 22 when the disc-shaped first handle 28 abuts against the top of the upper cover 22.
The first end outside the lower end of the upper cover 22 and the first end outside the upper end of the lower cover 21 are rotatably connected together, for example, by a plastic connecting strip 2C.
The upper end of the catch 26 is formed with a second handle, fig. 5, which is a boss formed on the upper end of the catch 26, to facilitate disengagement of the catch 26 from the teeth 27.
The lower end of the coupling head 24 is formed with a guide slope to facilitate the entry of the coupling head 24 into the annular inner edge of the lower cap 21.
In a standby state (for example, during transportation), the upper cover and the lower cover are combined together not only by the snap but also by the bolt, so that the upper cover and the lower cover are prevented from being accidentally separated during transportation.
Before use, the bolt is rotated upwards to make the combining head separated from the lower cover and enter the concave part of the upper cover, so that the upper cover and the lower cover are combined together only by means of buckling.
When the device is used, when a nurse needs to put a cotton swab with a collected sample into the reagent tube, the upper end of the buckle of the cover cap is pressed, and the buckle is separated from the convex teeth, so that the upper cover is separated from the lower cover; after the cotton swab is placed into the tube body, the buckle and the convex teeth are buckled again.
Finally (before transportation), the first handle is rotated to screw the combining head at the lower end of the bolt into the lower cover until the first handle is tightly pressed on the upper cover, so that the upper cover and the lower cover are firmly combined into a whole to avoid being opened accidentally during transportation. The operation of the step can be carried out by holding the rough surface of the periphery of the lower cover, so that the operation is not influenced by the disinfectant on the gloves and does not skid.
In the application, the reagent tube cap is decomposed into the upper cover and the lower cover, the opening of the reagent tube cap is also decomposed into two forms of loose combination and firm combination, and only the loose combination mode is adopted on the collection site, so that the rapid collection is convenient; and a firm combination mode is adopted in the transportation process, so that the cap cannot be accidentally loosened in the transportation process.
