Abstract

The invention discloses a dialyzer end cover. The dialyzer end cover comprises a cover body, wherein a cover mouth for a Luer interface is arranged on the cover body in a manner of extending upwards from the cover body; the cover body comprises a cover top and a cover wall, wherein a cavity is formed between the cover top and the cover wall; the cover mouth is connected to the cover top and communicates with the cover top; and an annular welding line which has the same axis as the cover top is arranged on one side close to the cover wall, of the inner surface of the cover top, the width of thewelding line is 0.7-0.8mm, and the width of the welding line is 0.5-1.0mm. The invention also provides a welding technology. The welding technology comprises a welding technology of the dialyzer endcover. The welding technology of the dialyzer end cover comprises the following steps of step 1, enabling the dialyzer end cover and a dialyzer body to be in cooperation and alignment; and step 2, performing welding work on the dialyzer end cover by an ultrasonic welding head, the welding depth is 0.8mm, the amplitude is maintained to be 85%, the pressure maintaining time is 2 seconds, the weldingtime is 0.3-0.8 seconds, and the output energy is 300-700 Joule. According to the dialyzer end cover and the welding technology thereof disclosed by the invention, the welding intensity between the dialyzer end cover and the dialyzer body is improved, and side leakage is avoided.

Description

technical field [0001] The invention relates to a dialyzer end cover welding process. Background technique [0002] At present, the existing dialyzer end caps are prone to side leakage due to the fitting method when they are combined, and the welded end caps are unreasonable in design, resulting in poor results after welding and prone to openings And other issues. Contents of the invention [0003] The purpose of the present invention is to provide a dialyzer end cap and its welding process, improve the welding strength between the dialyzer end cap and the dialyzer end cap, and avoid side leakage. [0004] In order to achieve the above object, the present invention provides a dialyzer end cap, which includes a cover body, and the cover body extends from the top with a cover mouth for the Luer interface; the cover body includes a cover top and a The top forms the cover wall of the cavity, the cover mouth is connected to the cover top and communicates with the cover top; t...
