[0003] How to add developing material to ordinary gauze? Patent No. 92216310 proposes an interlayer method, that is, the developer barium sulfate is filled between the two layers of rubber, and the developing gauze is embedded in ordinary gauze. The advantage is that the developing effect is good, but the disadvantage is that the barium sulfate powder may leak out and cannot be washed. , the developed gauze is too thick and lacks folding properties
The advantage is that it is easy to make, but the disadvantage is that it is inconvenient to use and cannot be folded
There are two disadvantages: one is that polyvinyl chloride is a chlorine-containing product, which has side effects on the human body and is not suitable for use in the human body. Some countries have already made legislation that does not allow polyvinyl chloride to be used in medical materials and food packaging materials; Thread-like, relatively thick, not washable, not easy to fold

Abstract

A medical developing fiber used and its production. We mix polypropylene, Barium sulfate, coupling molecules, plasticizer and lubricant together, mix round it, extrude it through plastic machine in fuse condition, cut grains and the masterbatch A comes into been. Drying masterbatch A and put it into screw extruder to extrude filature. Roll it into barrel (B) by strip roller to weave gauze. The fiber material made by this preparation belongs to green production. It has no poisonous side effect, good flexility, high strength, good tensibility and good latter processing. So it fits for the production of large-scale and consecutive. The gauze made by it has good development, can bear washing, bear pucker, has no poisonous and also can be disinfected in high temperature.

Description

technical field [0001] A fiber material for weaving medical gauze and a manufacturing method thereof. Background technique [0002] The doctor will count the amount of gauze before and after the operation. If there is a discrepancy, it may be left in the patient's body. At this time, it is necessary to confirm whether it is left in the patient's body. If it is ordinary gauze, there is no way to detect whether the gauze is left in the patient's body and where it is left. It can only be re-operated to search the patient's body, adding new pain to the patient. Therefore, medicine generally adopts the method for adding developing material in common gauze, so that whether gauze is left in the patient's body and where it is left in can be detected in advance with X-ray photography equipment outside the patient's body. This can avoid blind surgical search and reduce the suffering of patients. [0003] How to add developing material to ordinary gauze? Patent No. 92216310 propose...
