Abstract
The invention relates to the field of filtration equipment, and discloses a preparation method of a PE folded filter element material and a filter device thereof. The folded filter element is fixedly connected with a tee pipe, and the large particulate matter in the liquid is filtered through the folded filter element. The through pipe is connected, the sealing plug is detachably connected with the liquid inlet joint, the conduit is connected with the three-way pipe, and the liquid is output through the conduit. The injection shell is slidably connected with the shell, and the needle body communicates with the injection shell, so that the injection shell can slide relative to the shell to put the needle body into the shell. During the infusion, the clamping column fixes the injection shell and the shell. When the needle is pulled out, the clamping ring is turned to make the clamping column close to the clamping groove and allow the clamping column to slide in the clamping groove, so that the injection shell slides. The spring is fixedly connected with the shell, and the spring can Drive the injection shell back into the shell, thereby pulling the needle body into the shell, avoiding injury to medical staff.
Description
technical field [0001] The invention relates to the field of filtering equipment, in particular to a preparation method of a PE pleated filter element material and a filtering device thereof. Background technique [0002] With the improvement of people's living standards, indwelling needles with less damage to blood vessels have been widely used in clinical practice. However, after the puncture needle is drawn out during the infusion operation, it is separated from the indwelling needle, and the needle tip is easy to stab medical staff or other personnel, causing injury and cross infection to medical staff. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a preparation method of a PE pleated filter element material and a filtering device thereof, aiming at solving the problem that the existing indwelling needle is easily injured to medical staff after being taken out. [0004] In order to achieve the above object, in the first aspect, t...
