Correspondingly, a second rubber sleeve is fixed at the lower opening of the cylinder mouth, and the second thread is set on the second rubber sleeve. The first rubber sleeve and the second rubber sleeve can be fixed to the cylinder body and the cylinder mouth by gluing or other methods.

[0028] During design, the first rubber sleeve can be fixed on the inner wall of the cylinder body, that is, the outer wall of the first rubber sleeve is fixed on the inner wall of the cylinder body, and the inner wall of the first rubber sleeve is provided with a first thread. Correspondingly, the second rubber sleeve can be fixed on the outer wall of the cylinder mouth, that is, the outer wall of the second rubber sleeve is fixed on the outer wall of the cylinder mouth, and the outer wall of the second rubber sleeve is provided with a second thread.

[0029] In addition, the first rubber sleeve can also be fixed on the outer wall of the cylinder body. Correspondingly, the second rubber sleeve can be fixed on the inner wall of the cylinder mouth.

[0030] Furthermore, in order to ensure that the net bucket will not easily shake relative to the cylinder body after being placed inside the cylinder body, the utility model also provides a sealing sleeve 8 (such as a sealing sleeve 8) on the upper outer wall of the net bucket or the inner wall of the cylinder body for closing the gap between the net bucket and the cylinder body. Figure 1 As shown, the sealing sleeve is fixed on the inner wall of the cylinder body), and the sealing sleeve is a rubber sleeve that can be fixed on the inner wall of the cylinder body or the outer wall of the net barrel by bonding.

[0031] In order to facilitate taking and placing the net bucket, a vertical handle 7 is provided on the net bucket, such as at the center, and the height of the handle is greater than the height of the net bucket.

[0032] Below, taking the cylinder body and the cylinder mouth being separated, and the net bucket and the net bucket bracket being fixed together as an integrated structure as an example, the use process of the medical anti-pollution waste liquid cylinder of the utility model is briefly described:

[0033] Place the net bucket with the net bucket bracket in the body of the waste liquid cylinder, and then assemble the body and the mouth of the cylinder to form a waste liquid cylinder; then, place the assembled waste liquid cylinder in the experimental area, and place the waste liquid used for the experiment and sharp objects such as discarded sample pipette tips into the waste liquid cylinder through the opening of the mouth of the cylinder. Sharp objects such as sample pipette tips will remain in the net bucket, and the waste liquid will flow into the body of the cylinder through the mesh of the net bucket. After the experiment is completed, separate the body and mouth of the waste liquid cylinder, take out the net bucket in the body, and then place the sharp sample pipette tips and other solid waste collected in the net bucket into a sharps box or special container, pour the waste liquid collected in the waste liquid cylinder into a waste liquid bag, and finally clean and disinfect all parts of the waste liquid cylinder.

[0034] The utility model medical anti-pollution waste liquid cylinder has the following advantages during the test process: ① The assembled waste liquid cylinder can be placed in the experimental area, such as a biological safety cabinet, for easy storage and safe use. ② During the operation, the waste liquid in the pipette gun or pipette is placed in the waste liquid cylinder, and the splashing liquid will splash onto the surrounding cylinder wall. However, due to the circuitous design of the mouth of the waste liquid cylinder, the possibility of liquid splashing onto the surface of the operating instrument is reduced. ③ The discarded sample pipette tips are placed in the waste liquid cylinder. Since a net bucket is placed inside the cylinder body, the sharp sample pipette tips can be separated from the waste liquid. ④ After the experimental operation is completed, the cylinder body is separated from the cylinder mouth, and the net bucket inside the cylinder body is taken out. The items collected in the net bucket can be placed in a sharps box or a special container to reduce punctures to cleaning personnel; and the waste liquid collected in the cylinder body can be poured into a waste liquid bag without flowing out and polluting the environment. ⑤Finally, the waste liquid tank can be cleaned, assembled and dried for later use; if a sterile operation experiment is designed, the various components of the waste liquid tank can be placed in a pressure cooker for disinfection and assembled for later use.
