Wearable Patch: A new invention of scientists to inject medicine into the layers of the skin without piercing the needle.
American researchers have launched another new treatment method in the history of medicine. A method of injecting medicine from the skin without piercing the needle was invented. For this, the researchers of Massachusetts Institute of Technology in America have created a device like a patch (Wearable patch) which is easily attached to the skin. Drugs are added to this patch and are designed to be injected into the body through the skin. Its specialty is that the drug is injected into the layers of the skin without the need for a needle to be inserted.
Currently we are treating illnesses with injections or medicine. But sometimes the injections cause a lot of pain to the patient. Some medicines are bitter and make the mouth tingle. Moreover it has to pass through the digestive system. This can lead to gastric problems. The latest patch will be checked for these.
Testing like this..
The patch uses ultrasonic waves to create tiny channels in the dermis layer. It then injects the drug through these channels painlessly. After that, it makes sure that the drug has an effect on the target area.
Niacinamide, a B vitamin found in sunscreens and moisturizers, has been tested experimentally by Massachusetts researchers. It was tested by inserting it into the body with the help of an ultrasound patch. It gave good results. The researchers revealed that the drug worked almost 36 times better in this approach compared to the ratio of the drug going into the skin. While the micro needling process used to take six hours to inject drugs, this procedure took only half an hour, he said.
- How does it work?
This light weight patch can be easily worn on the skin. It is embedded with piezoelectric transducers. It helps to convert electric current into mechanical energy. Once activated, these transducers generate pressure. Scatter the skin cells and form micro-routes to allow the drug to penetrate. This medicine goes into the body.
- More research in the future
At present, this device is designed to deliver medicine only through the skin. In the future, it will be modified so that the drug goes into the blood vessels of the body. Once this patch is available, hormones like progesterone can be delivered in a simple way in the body. Also, can such devices be made to treat deadly diseases like cancer? Researchers are investigating the issue.
