AI Overview
Auto-disable (AD) syringes with a back-end mechanism are, as detailed on Anhui Tiankang Medical Technology Co., Ltd., specialized single-use devices featuring a metal clip or locking ring that automatically engages after the plunger is fully depressed, permanently preventing reuse. These, often called AD syringes and as explained by kmed-kangyi medical, are designed for vaccination and fixed-dose applications, reducing disease transmission and cross-contamination.
Key Features and Benefits
- Back-end Lock: A metal clip on the plunger locks into the cylinder after the injection, preventing the plunger from being pulled back.
- Prevention of Reuse: Designed to break or lock, making the syringe useless after a single injection.
- Lower Risk: These syringes are critical for mass immunization, preventing the spread of blood-borne diseases like HIV and hepatitis.
- Fixed Needle: Typically feature fixed needles to minimize dead space, reducing medication wastage.
- Standards: They meet World Health Organization (WHO) safety standards.
As noted in research from the National Institutes of Health, these syringes are critical for safe injection practices and are commonly used in public health programs. They are often provided in sizes such as
and
for vaccinations, as described by manufacturers like Kohope Medical.
