New practical ampoule patent brief description

The Department of Immunology, Tianjin Medical University obtained a patent for a new type of practical ampoule, patent application number from Mr. Yongchuan Yong. The utility model discloses an ampoule, which is composed of a bottle body, a bottle neck, a bottle bubble, a color point, a main nick, a secondary nick, and a lateral nick. Two minor nicks were cut at intervals of 1 to 2 mm on both sides of the main nick on the bottleneck annular surface just below the color point. According to the requirement of the ampoule breaking force control, two side nicks are cut at 1 to 2 mm apart on both sides of the two sub-slits. For breaking force control of larger capacity specification ampoules, multiple scores can be taken from the neck of the bottleneck, each nick being 1 to 4 mm apart. Because of the reduced breaking force of Ampoule, it can be opened by freehand and facilitates clinical work. Its cost is low and its quality control is stable. The position of the opening of the ampule and the shape of the opening are also controlled to a certain extent, which reduces particulate pollution and saves manpower and material resources.
