In the above technical solution, the device further includes a sliding rail portion 510, a sliding block portion 520, and a limiting portion 530, where the sliding rail portion 510 is connected to the collecting container 300, the sliding block portion 520 may slide on the sliding rail portion 510, the extending direction of the sliding rail portion 510 is a direction from an inner bottom wall of the collecting container 300 to a collecting opening of the collecting container 300, when the sliding block portion 520 is fixed, the collecting container 300 may move from the inner bottom wall of the collecting container 300 to the collecting opening direction of the collecting container 300, so as to achieve that the second nozzle is close to or far from the inner bottom of the collecting container 300, the sliding block portion 520 may be connected to the catheter 200, not only can satisfy the functional requirement, but also can improve the integration of the device, and avoid occupying too much space, and both ends of the sliding rail portion 510 may also be provided with the limiting portion 530, the limiting portion 530 may abut against the sliding block portion 520 when the sliding block portion 520 slides to both ends of the sliding rail portion 510, and the limiting portion 520 may continue sliding to slide, thereby avoiding the sliding block portion 520 from being separated from the sliding rail portion 510, and being beneficial to improving the safety of the device.
In some examples, the rail portion 510, the slider portion 520, and the stopper portion 530 are all made of thermoplastic resin.
In the above technical solution, the sliding rail portion 510, the sliding block portion 520 and the limiting portion 530 are all made of thermoplastic resin, for example, polyethylene can be used to improve the corrosion resistance of the sliding rail portion 510, the sliding block portion 520 and the limiting portion 530, the sliding rail portion 510, the sliding block portion 520 and the limiting portion 530 are inevitably contacted with the liquid chemical agent after long-term use, and the improvement of the corrosion resistance of the sliding rail portion 510, the sliding block portion 520 and the limiting portion 530 can avoid the failure of the sliding rail portion 510, the sliding block portion 520 and the limiting portion 530 due to chemical corrosion, which is beneficial to improving the service life of the device.
