Wisman High Voltage Power Supply for Ampoule Bottle, Penicillin Bottle Oxygen Resistance, Residual Oxygen, Sealing and Other Medical Supplies Sealing Test Solutions

Application Specification

Background

The sealing test solution of medical supplies has high stability and reliability, high acquisition accuracy, and continuous adjustable output voltage; Overvoltage, overcurrent, arc and other protection; Control interface adopts industrial interface, from the power supply principle to the overall structure in accordance with industrial design; High integration, high determination accuracy, high detection accuracy; Easy to control, easy to operate.

In order to realize the comprehensive monitoring of the quality of biomedical packaging, that is, the quality and efficiency control of packaging production line - the quality inspection and control of packaging products, and the comprehensive detection of drug packaging safety risks, pharmaceutical enterprises and pharmaceutical packaging material manufacturers must have professional, scientific and convenient drug packaging testing instruments and control means.

Wisman high voltage power supply, has been committed to pharmaceutical packaging quality testing technology research and development and services, with professional testing power equipment tailored for pharmaceutical packaging, can provide enterprises with convenient, reasonable and accurate packaging quality testing solutions.

The sealing test solution for medical supplies is specially designed for medical celling bottles, ampoules, cartridge bottles, infusion bottles, infusion bags, BFS, tablet bottles, eye drops bottles, pre-filled syringes and other containers to achieve rapid, efficient and safe detection of defective products in ampoules and Celling bottles, improve detection efficiency and reliability.

As one of the commonly used packaging forms of medicine, ampoules and xylin bottles, some testing items need to be focused on. At the same time, with the official promulgation and implementation of the 2015 version of the pharmaceutical packaging material standard, GB/T2637-2016 and YBB related standards, the quality and performance testing of ampoules and Xylin bottles has a more detailed and specific implementation basis. The test items that need to be focused on are: the oxygen resistance test of ampoules and Xylin bottle packaging, the residual oxygen detection and the sealing performance test.

Implementation Principle

As shown in Figure 1, the two ends of the packaging container are respectively connected with two electrodes, the emitter and the receiver. C1 and C2 respectively represent the capacitance formed between the transmitting electrode and the container solution, and between the receiving electrode and the container solution (due to the insulation barrier of the outer wall of the container, the electrode cannot contact the solution, so the capacitance is formed). Z1 and Z2 respectively represent the capacitive reactance generated by C1 and C2. R stands for the resistance of the solution itself.

When the packaging container is intact and there is no leakage, the detection loop as shown in Figure 2 generates induced micro-current I1, that is, I1=V/ (Z1+R+Z2).

When the packaging container leaks, the capacitance formed between the outer wall of the container and the electrode disappears, that is, breakdown, so that the capacitance reactance generated by the capacitor is zero, at this time the induced micro current generated in the detection loop is I2, that is, I2=V/(R+Z2), as shown in Figure 3 equivalent circuit diagram.

Judging whether the packaging container is leaking or not depends on the current measured in the detection loop, and the difference in current △I, that is, △I=I2-I1, is used as the criterion for judging whether the container is qualified.
