Detailed Description
The utility model will be further described with reference to the following drawings and specific examples, which are not intended to limit the utility model thereto.
Example 1
As shown in fig. 1-5, the coronavirus nucleic acid sampling device provided by the present invention comprises a preservation liquid bottle 1, a cover body 2 and a thimble 9, wherein the inner top of the preservation liquid bottle 1 is fixedly connected with a support plate 7, the support plate 7 is provided with a notch 8, the bottom of the preservation liquid bottle 1 is annularly provided with three first plane structures 4, which are convenient for taking the preservation liquid bottle 1, the cover body 2 is internally and fixedly connected with a grid retaining ring 22, the grid retaining ring 22 is located at the middle part of the cover body 2, as shown in fig. 4-5, the bottom of the grid retaining ring 22 is fixedly connected with a convex liquid outlet 10, the vertical height of the bottom end of the convex liquid outlet 10 and the grid retaining ring 22 is smaller than the vertical height of the thick end of the thimble 9 and the upper part of the grid retaining ring 22, so that when the upper threaded cover area 21 is threadedly mounted on the preservation liquid bottle 1 (i.e. when the thick end of the thimble 9 is in contact with the support plate 7), the lower protective film 12 can be stably pushed through, the bottom of the convex liquid outlet 10 is provided with a lower protective film 12, the side wall of the cover 2 is annularly provided with three second plane structures 5, which facilitate the rotation and taking of the cover 2, as shown in fig. 4-5, the inside of the cover 2 is equally divided into two parts by a check retaining ring 22, the bottom of the cover 2 at the check retaining ring 22 is a lower screw cap area 20, the top of the cover 2 at the check retaining ring 22 is an upper screw cap area 21, an upper protective film 3 is connected in the top of the cover 2, the bottom of the upper protective film 3 is abutted against the thick end of the thimble 9, the connection position of the inner side wall of the upper protective film 3 and the upper screw cap area 21 is provided with an intermittent connection strip 6, as shown in fig. 2, the connection position of the upper protective film 3 and the upper screw cap area 21 is provided with an intermittent connection strip 6, but not provided with a whole circle, but a part of fixed connection position is left, thus the upper protective film 3 is prevented from falling off and directly covering on the support plate 7 to influence the liquid in the preservation bottle 1 And when the testing device is not used, the thimble 9 is limited, and the tip of the thimble 9 is abutted against the lower protective film 12.
When the device is used, a detector unscrews the cover body 2 from the top of the preservation liquid bottle 1, inserts the swab end into the preservation liquid bottle 1 through the notch 8 on the supporting plate 7, then removes the swab to be in contact with liquid in the preservation liquid bottle 1, then slightly shakes the swab, then the detector connects the other end of the cover body 2 with the top of the preservation liquid bottle 1 in a threaded mode, and the upper protective film 3 can be burst through the top opening of the preservation liquid bottle 1. Then the butt of thimble 9 can contact with the upper portion of backup pad 7, under the state of continuously screwing up, thimble 9 can break away from the constraint of three fixed strip 11, the pointed end of thimble 9 can break through the pointed lower protection film 12 of convex type liquid outlet 10, later the person of examining can extrude the liquid in the liquid storage bottle 1 from the breach department of lower protection film 12, only need exchange lid 2 from top to bottom, then screw up on the top of liquid storage bottle 1 can, the play liquid end of having avoided lid 2 needs prick the hole in advance, save one-step detection step, and then improved medical personnel's efficiency that detects.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
