Jet injector

Jet injector is a type of medical device used for injections without a needle. They are powered by high pressure, forcing the medicine through a tiny orifice, creating a narrow jet of fluid that penetrates the skin.

History

The concept of jet injection began in the 1860s. The first patent was awarded to Marshall Lockhart, an American inventor, in the 1930s for a device that used a spring-loaded mechanism to deliver injections.

Design

Jet injectors are designed to deliver a precise dose of medication at a controlled rate. The device consists of a reservoir for the medication, a high-pressure mechanism, and a nozzle with a tiny orifice through which the medication is forced.

Types

There are several types of jet injectors, including single-dose, multi-dose, and disposable injectors. Single-dose injectors are used for one injection and then discarded. Multi-dose injectors can be used for multiple injections, and disposable injectors are designed to be used once and then thrown away.

Uses

Jet injectors are used in a variety of medical settings, including vaccination programs, diabetes management, and anesthesia delivery. They are also used in the military for mass immunization campaigns.

Advantages

The main advantage of jet injectors is that they do not require needles, reducing the risk of needlestick injury and bloodborne disease transmission. They also allow for rapid delivery of medication, making them ideal for mass vaccination campaigns.

Disadvantages

Despite their advantages, jet injectors have some disadvantages. They can cause pain and bruising at the injection site, and there is a risk of cross-contamination if the injector is not properly cleaned between uses.
