Borosilicate glass sleeve for pen type syringe and preparation method of borosilicate glass sleeve

Abstract

The invention relates to pharmaceutical glass, in particular to a borosilicate glass sleeve for a pen type syringe and a preparation method of the borosilicate glass sleeve. The borosilicate glass sleeve is characterized by comprising chemical composition of SiO2, Al2O3, B2O3, K2O, Na2O, CaO, MgO, BaO and Fe2O3. The preparation method includes steps: firstly, using a forming machine to forming the pharmaceutical neutral borosilicate glass sleeve; secondly, annealing the formed glass sleeve in an electric annealing furnace; thirdly, visually checking the glass sleeve, and fourthly, packaging and storing. The borosilicate glass sleeve and the preparation method have the advantages that the glass performance can reach the first-level waterproof requirement by means of the materials and the preparation method, content of silica, alumina and boron trioxide is high, and content of alkali metallic oxide is low, so that high chemical stability, thermal stability and mechanical strength or products can be guaranteed.

Description

technical field [0001] The invention relates to a medicinal glass, in particular to a borosilicate glass sleeve for a pen type injector and a preparation method thereof. Background technique [0002] For a long time, the injection products produced by Chinese pharmaceutical companies have been packaged in traditional packaging. The pen-type syringe is a new generation of injection packaging container that appeared in the international market in 2002. Its appearance better meets people's needs for easy use and safe medication. requirements, and will lead to epoch-making changes in the packaging of water injection and powder injection products and the way of clinical medication. [0003] There are two defects in traditional injection packaging: First, there are hidden dangers in the safety of patients' medication. Before the injection is used, when the operator breaks the ampoule, fine glass powder will be produced. These glass powders may be mixed with the medicine and cause...

Problems solved by technology

[0003] There are two defects in the traditional injection packaging: First, there are hidden dangers in the patient's medication safety

Before the injection is used, when the operator breaks the ampoule, it will produce fine glass powder, which may be mixed with the medicine and cause harm to the patient; at the same time, when the injection is sucked into the syringe, the medicine is exposed to the air , prone to particulate and microbial contamination

Second, the use process is complicated and inefficient

[0004] In addition, traditional packaging will indirectly cause some social problems, such as a large number of disposable plastic syringes will form white pollution, and there is a danger of spreading diseases such as AIDS during use and recycling.
