Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a sample separating and extracting device for HPV detection comprises a protective shell 1, a spring 2, a fixed plate 3, a limiting block 4, a movable box 5, a poking wheel 6, a gear 7, a rotating shaft 8, a silica gel pad 9, a soft brush 10, a shielding plate 11, an inlet and an outlet 12, a partition plate 13, a sliding chute 14, an end cover 15 and sealing rubber 16, wherein the spring 2 is fixed in the protective shell 1, the right end of the spring 2 is fixed on the fixed plate 3, the limiting block 4 is fixed at the lower end of the fixed plate 3, the limiting block 4 is arranged in the protective shell 1, the movable box 5 is fixed at the upper end of the fixed plate 3, the poking wheel 6 is fixed on a bearing in the movable box 5, the poking wheel 6 is mutually connected with the gear 7, the gear 7 is fixed on the rotating shaft 8, the rotating shaft 8 is fixed on the movable box 5 by a bearing, the silica gel pad 9 is fixed at the tail end of the rotating shaft 8, the silica gel pad 9 is provided with the soft brush 10, the shielding plate 11 is fixed on the protective shell 1, and sunshade 11 and activity case 5 interconnect, seted up exit 12 on the protecting sheathing 1, and the protecting sheathing 1 internal fixation has a baffle 13 to seted up spout 14 on the baffle 13, be provided with fixed plate 3 in the spout 14 simultaneously, end cover 15 and protecting sheathing 1 interconnect, and the inboard sealing rubber 16 that is fixed with of end cover 15.

The fixed plate 3 and the protective shell 1 form an elastic mechanism through the spring 2, the fixed plate 3 and the protective shell 1 form a sliding mechanism through the limiting block 4, when the sample extraction device is used up, the movable box 5 is loosened, the movable box 5 automatically restores to the original position under the action of the spring 2, and the limiting block 4 is used for ensuring that the movable box 5 keeps stable in the movement process.

The diameter of thumb wheel 6 is greater than the diameter of gear 7, and 2-4mm of the planar distance of the upper end of thumb wheel 6 from the planar distance of the upper end of movable box 5, through stirring thumb wheel 6, can drive thumb wheel 6 and rotate, and the transmission effect between cooperation thumb wheel 6 and gear 7 can make rotation axis 8 carry out stable rotation to the convenience is to the extraction of sample.

The rotating shaft 8 and the movable box 5 are vertically distributed, the length of the rotating shaft 8 is 8-10cm, and when the movable box 5 is pushed to drive the rotating shaft 8 to move, the problem that a detected person feels uncomfortable when a sample is stuck by the silica gel pad 9 and the soft brush 10 at the front end of the rotating shaft 8 is avoided through the fixed length of the rotating shaft 8.

Be sliding connection between sunshade 11 and the protecting sheathing 1, and sunshade 11 is beta structure, when the activity case 5 removed, through the folding flexible effect of sunshade 11, can be convenient for activity case 5 moves, guarantees again to use the completion back, and protecting sheathing 1 can form relative confined space through sunshade 11 and keeps the protection to the sample, can avoid the sample to lose or be contaminated, can avoid again leading to the fact the infection with the contact of other people.

For parallel distribution between baffle 13 and the rotation axis 8, and baffle 13 passes through and constitutes slide mechanism between spout 14 and the fixed plate 3, when the movable box 5 removes, drives fixed plate 3 and moves together, through the limiting displacement of spout 14 on the baffle 13, avoids fixed plate 3 to rock, and then guarantees fixed plate 3 and removes the stability of in-process.

The working principle is as follows: as shown in fig. 1-4, when using the sample separation and extraction device for HPV detection, firstly, both hands of a sampling person are protected, the protective housing 1 is taken out, the end cap 15 is pulled out for use, when using, the movable box 5 is pushed forward, so as to drive the fixed plate 3 and the limit block 4 to move forward, further the fixed plate 3 slides in the chute 14 on the partition plate 13, and the limit block 4 slides in the slot at the bottom end of the protective housing 1, so as to ensure the stability of the movable box 5 in the moving process, when moving the movable box 5, the rotating shaft 8, the silica gel pad 9 and the soft brush 10 are driven to move leftward, and the shielding plate 11 moves leftward, folds and contracts, the rotating shaft 8, the silica gel pad 9 and the soft brush 10 move outward through the inlet and outlet 12 on the protective housing 1, so as to make the rotating shaft 8, the silica gel pad 9 and the soft brush 10 enter the female vagina for sample extraction, and the length of the rotation axis 8 is defined so as to avoid discomfort for the patient during the sample extraction;

when the sample is extracted, in order to ensure the quality of the sample, the dial wheel 6 can be shifted, the rotating shaft 8, the silica gel pad 9 and the soft brush 10 can be rotated through the rotating action of the dial wheel 6 and the gear 7, so that the quality of the sample is ensured, the silica gel pad 9 and the soft brush 10 are made of soft materials and cannot damage the female body, after the extraction is completed, the movable box 5 is loosened, the whole device is restored under the action of the spring 2, so that the rotating shaft 8, the silica gel pad 9 and the soft brush 10 move rightwards to enter the protective shell 1, the shielding plate 11 moves rightwards to expand and block the opening, the end cover 15 covers the inlet and the outlet 12 at the left end of the protective shell 1, the protective shell 1 is sealed under the action of the sealing rubber 16, the protective shell 1 forms a relatively closed environment to protect and store the sample, and the sample is prevented from being damaged and directly contacted with an outsider, therefore, the safety of the sample is ensured, the health of the outsiders is protected, and the occurrence of contact type infection is avoided, which is the working principle of the sample separation and extraction device for HPV detection.

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 invention, the scope of which is defined in the appended claims and their equivalents.
