A single-stage pressure-resistant testing device for medical dialysis paper

Abstract

The invention relates to a single-stage pressure-resistant testing equipment for medical dialysis paper. The equipment includes a test base plate and test dialysis paper; the middle part of an upper end surface of the test plate is provided with a pull test device; two tension devices are symmetrically installed on both sides of the upper end surface of the test plate; a beginning end of the dialysis paper penetrates from a tension device at the right side of the test base paper; the middle part of the test dialysis paper penetrates through the pull test device; the pull test device can conduct a third-stage tensile test on the test dialysis paper; taking the average value of the three tensile test as a final test value, thereby eliminating the accidental error in manual test tensile test. The compressive property test has high precision, and the tension devices can carry out self tension adjustment on both sides of the test dialysis paper, and no manual adjustment of tension is needed. The invention can realize the accurate automatic tension test function of compression performance of the dialysis paper.

Description

technical field [0001] The invention relates to the technical field of medical dialysis paper manufacturing, in particular to a single-stage anti-pressure detection device for 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. Existing testing...
