The collection assembly includes a spatula 6, a connecting tube 603, an extraction tube 302 and a negative pressure generator. The spatula 6 is fixedly arranged on the outer peripheral surface of the second rotating shaft 5, the spatula 6 is correspondingly arranged with the scraping plate 101, and one end, far away from the second rotating shaft 5, of the spatula 6 is tangential to the inner wall of the scraping plate 101, so that the spatula 6 can collect samples on the scraping plate 101. The second rotating shaft 5 is internally provided with a sampling hole 602, the connection part of the spatula 6 and the second rotating shaft 5 is provided with a communication hole 601, and the communication hole 601 is communicated with the sampling hole 602. The connecting pipe 603 is rotatably connected to one end, far away from the spatula 6, of the sampling hole 602, a fixing rod 604 is fixedly arranged inside the pipe body 1, and the fixing rod 604 is fixedly connected with the connecting pipe 603. The end of the connecting tube 603 remote from the sampling hole 602 is fitted with a one-way valve 702 on the sampling cartridge 7. The negative pressure emitter is fixedly arranged in the handle 3, one end of the air extraction pipe 302 is fixedly communicated with the negative pressure generator, and the other end of the air extraction pipe 302 is matched with the one-way valve 702 at one end, far away from the connecting pipe 603, of the sampling box 7. When the handle 3 is installed, the connection tube 603 is inserted into the check valve 702 at one end of the sampling cartridge 7, so that the connection tube 603 communicates with the inside of the sampling cartridge 7. And the air exhaust pipe 302 is inserted into the one-way valve 702 at the other end of the sampling box 7, so that the air exhaust pipe 302 is communicated with the inside of the sampling box 7.

A control button 301 is fixedly arranged on the handle 3. The handle 3 is internally and fixedly provided with a controller, and the control button 301, the negative pressure generator and the double-headed motor 4 are electrically connected with the controller. The double-headed motor 4 and the negative pressure generator are controlled to work through the control button 301 and the controller, so that the sampling work is more convenient and quicker.

Working principle: in use, a new sampling cassette 7 is first removed. Then the handle 3 is unscrewed from the tube body 1, and the second protruding block 701 on the sampling box 7 is aligned with the clamping groove on the inner wall of the tube body 1 and is put in. The suction tube 302 on the handle 3 is then aligned with the one-way valve 702 of the sampling cartridge 7 near the end of the handle 3 and the one-way valve 702 is inserted. Then the handle 3 is screwed down, the handle 3 gradually moves towards the direction of the tube body 1, the top block 304 on the handle 3 presses the sampling box 7, and the connecting tube 603 is further inserted into the one-way valve 702 at the other end of the sampling box 7. With the tightening of the handle 3, the top block 304 stably fixes the sampling cassette 7 in the tube body 1.

Then, the hand-held handle 3 is used for inserting the tube body 1 into the cervical canal by rotating the sleeve 2, and after the sampling depth is reached, the double-headed motor 4 and the negative pressure generator are controlled to be started by the control button 301. The double-headed motor drives the rotating sleeve 2 to rotate through the first supporting rod 203, so that the rotating sleeve 2 drives the push block 201 to rotate. When the push block 201 is separated from the scraping plate 101, the scraping plate 101 rotates outside the tube body 1 by taking the first rotating shaft 102 as a center of a circle under the action of the torsion spring, so that the scraping plate 101 is in contact with the inner wall of the cervical canal. Along with the continuous rotation of the rotating sleeve 2, the pushing block 201 gradually extrudes the scraping plate 101, so that the scraping plate 101 rotates towards the tube body 1 by taking the first rotating shaft 102 as the center of a circle, and the scraping plate 101 scrapes samples on the inner wall of the cervical canal.

At the same time, the double-headed motor 4 drives the second rotating shaft 5 to rotate, so that the second rotating shaft 5 drives the spatula 6 to rotate. So that the spatula 6, when in contact with the scraping plate 101, collects the sample on the scraping plate 101 into the spatula 6. Since the negative pressure generator at this time vacuums the inside of the sampling cartridge 7 and the connection tube 603 through the suction tube 302, the air pressure in the communication hole 601 and the spatula 6 is low, and when a sample enters the spatula 6, it is sucked into the communication hole 601 and enters the sampling cartridge 7 through the sampling hole 602 and the connection tube 603. Since the through hole of the sampling box 7 is provided in the middle, the sample can fall on the arc-shaped inner wall of the sampling box 7.

As the double-headed motor 4 continues to rotate, the scraping plate 101 is continuously opened and closed to sample. When the sampling is finished, the double-headed motor 4 and the negative pressure generator are turned off by the control button 301. After the control button 301 is pressed, the output shaft of the double-headed motor 4 can be rotated to the position before starting up, so that the rotating sleeve 2 drives the push block 201 to completely press the scraping plate 101 back into the pipe body 1, and the pipe body 1 is conveniently pulled out. And then the double-headed motor 4 is closed, and the tube body is pulled out.

Finally, the sample can be stored or detected by unscrewing the handle 3. As the handle 3 moves away from the body 1, the suction tube 302 is pulled out of the check valve 702, and the check valve 702 is closed. The cartridge is then pulled out of the tube 1, at which time the connecting tube 603 is pulled out of the other one-way valve 702. After the sample cartridge is removed, both check valves 702 are closed, avoiding sample spillage or contamination.

Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
