What is an autoinjector?
Auto-injector is a medical device designed to provide a pre-dose of the drug. There are many variants; Their relative ease of using patients or other untrained persons makes the auto-injector an ideal tool for rapid administration of drugs rescue life. Although they have evolved for patients hesitating to injure their own drugs, world militants have accepted the equipment for soldiers who may have to serve antidots for chemical war agents. Since 2011, research has been conducted in creating more reliable and safer auto-injectors. Before use, the patient removes a plastic cap protecting the syringe assembly. At this point, the needle is not visible because it is still inside the device. Placing the automatic injector on the thigh, the patient presses the button on the opposite end of the injector. The button releases the spring that quickly puts the needle and administration. Depending on the type of injection, the device may indicate when the patient can remove the needle.
alllitariansils around the world are one of the largest customers of automatic injectors. For example, an automatic injector containing antidote for chemical war agents is a standard equipment for soldiers serving in the United States armed forces. Chemical war reagents are rapidly acting on the human nervous system, which means that soldiers have only seconds to serve drugs saving life like atropine. Atropine, although it has many medical uses, is an antidote against organophosphate poisoning. The administration of one dose of atropine protects against sarin, VX, tabun and soman, some of the most common chemicals.
Although automatic injector plays a major role that protects soldiers, civilian patients with different health conditions benefit from the use of equipment. For examples, many individuals susceptible to severe allergic reactions, the injector's epinephrine car has a injection. A patient or someone close can use the injection to preventanaphylactic shock. Patients with multiple sclerosis regularly use auto-injectors containing interferon to slow down the disease progression. Regardless of the easy use of equipment, patients and those who spend a long time with patients, they should learn the right techniques for drug administration.
Since the automatic injector is a widely used piece of medical equipment, research continues to produce better injectors. For example, because the army needs long lifetime injectors, newer injectors have plastic syringes rather than glass. Another research has once made a bulky current injector to the size of the pen size used diabetics to supply insulin.
