A multi-level test equipment for compressive performance of medical dialysis paper

Abstract

The invention relates to medical dialyzing paper compression resistance multilevel test equipment. The equipment comprises a test bottom plate and test dialyzing paper. A tension test device is installed in the middle of the upper end face of the test bottom plate. Two tensioning devices are symmetrically installed on the two sides of the upper end face of the test bottom plate. The head end of the test dialyzing paper penetrates in the tensioning device located on the right side of the test bottom plate. The middle of the test dialyzing paper penetrates through the tension test device. The tail end of the test dialyzing paper penetrates out of the tensioning device located on the left side of the test bottom plate. The tension test device can be used for conducting a three-level tension test on the test dialyzing paper under the assistance of the two tensioning devices. The average value of three tension test values is taken as the final test value, so that accidental errors existing in a manual tension test are eliminated, and the compression resistance test precision is high; the tensioning devices can conduct self-tension adjustment on the two sides of the test dialyzing paper, and therefore manual tension adjustment is not needed. Through the equipment, a precise and automatic tension test function of compression resistance of the dialyzing paper can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical dialysis paper manufacturing, in particular to a multi-stage test equipment for the compressive performance of medical dialysis paper. Background technique [0002] Dialysis paper is mostly used in medical sterilization. One side is high-density polyethylene. It is mainly used for sterilization of some high-end third-class medical device blister packaging. The advantage of dialysis paper is that it can enter and exit steam, but it is impermeable. It can be sealed with a sealing machine from time to time; performance testing is always required before the new dialysis paper is produced and leaves the factory. The poorer the ability, the worse the toughness of the dialysis paper. When it is over-extruded or has a sharp part when packing, the dialysis paper with low toughness is easy to be punctured, which leads to sterilization failure. Compressive performance testing must be carried out before. Ex...
