Double-side vacuum large volume injection and process for detecting liquid leakage rapidly

Abstract

The invention relates to double-side vacuum large volume injection and a process for detecting liquid leakage rapidly. The large volume injection comprises internal package, medicinal liquid in a bag and an external protective bag outside the internal package. The process for detecting the liquid leakage of the internal package comprises the following steps of: vacuumizing a space between the external protective bag and the internal package, wherein the relative vacuum degree is from -0.05 Pa to -0.1 Pa; placing the injection in a temporary storehouse for 13 to 15 days; turning the large volume injection out to detect under illumination of 2,000 Lux, wherein when obvious water mist or droplet between the large volume injection and the external protective bag is detected, micro-leakage is generated; and removing the large volume injection with micro-leakage. Due to the adoption of the process, the large volume injection with micro-leakage or potential micro-leakage can be exposed rapidly in 15 days and the large volume injection can be removed, so that the process reduces leakage rate of the manufactured bags to 0.003 to 0.005 percent and ensures the health of the people.

Description

technical field [0001] The invention relates to the field of manufacturing large-capacity injections for medical use. Background technique [0002] Large-capacity injections, that is, for intravenous infusion, including glass bottle infusion, plastic bottle infusion, soft bag infusion and upright infusion bag, and infusion bag can be packed vertically. [0003] During the production, packaging, and delivery of large-capacity injections, micropores or micro-slits may occur in very few packages due to accidental factors, resulting in leakage of the liquid medicine. [0004] Such as glass bottle infusion, in the process of production, packaging or transportation, due to the collision between glass bottles; in the process of blow molding of plastic bottles, there may be factors such as uneven thickness on the local bottle body, resulting in leaks or leaks ;Soft bag infusion or vertical infusion bag, vertical infusion bag, because of the edge sealing process around the bag body ...

Problems solved by technology

On the other hand: other external factors (such as harmful gases, air) will also affect the stability and biological characteristics of the liquid medicine, which may cause the liquid medicine to deteriorate or cause harm to the patient's body.

[0007] In terms of controlling the microleakage of large-capacity infusions, most infusion manufacturers can only use artificial quality control in the production process to prevent products with microleakage from leaving the factory. However, due to the diversity and status of microleakage products The inconspicuousness, it is difficult to effectively artificially control
