Successfully developed non-needle syringe

Researchers at the Massachusetts Institute of Technology (MIT) have said they have successfully built a high-pressure syringe that can deliver drugs through the skin without the need for needles. More specifically, this syringe can also be programmed into the dosage of the drug as well as the depth that the drug needs to reach.

Decades earlier, scientists have been trying to develop solutions to put drugs into the body and one of the solutions they found was medical medicine. However, the disadvantage of this patch is that only the drugs with the smaller pore size go through the skin.

Later, due to the increasing demand for non-needle syringes, many other scientists also thought of high-pressure syringes to inject drugs into the skin like the MIT group, and some of those syringes are actually has been commercialized in the market. However, the disadvantages of these syringes are that they are not customizable in terms of dosage and injection pressure, because their mechanism is based on the thrust of the accompanying spring.

Faced with that situation, the MIT team decided to develop a syringe that could transfer the amount of medication it wanted to the arbitrary depth under the skin. Instead of using springs, they used a device with another mechanism called the Lorentz force stimulator (Lorentz-force actuator).

This exciter has a small but very powerful magnet surrounded by a coil attached to the piston inside the syringe. When the current flows through the coil, this stimulator will interact with the magnetic field and create very strong force pushing the piston forward, causing high pressure and high velocity spray through the syringe tip to penetrate deeper. skin. The size that this injection leaves is only as small as that of mosquitoes.

The advantage of the new mechanism is that the pressure on the drug can always be adjusted by reducing the current flowing through the tube. Therefore, it allows to precisely and accurately adjust the amount of medicine and drug depth to the skin.

During the experiment, the group also found that the same drug pressure but with different subjects / skin areas, the penetration depth of the drug is also different. Since then, profiles corresponding to different subjects such as children, women, middle-aged . have been created by the group in order to create convenience when using in practice.

In terms of the effect of the new syringe, scientists say that besides reducing pain for injecting people as well as the absence of venous anomalies, it also helps doctors to avoid infection by any disease. be hit by a needle. It is not uncommon for medical staff to work with traditional syringes.

The team said they are currently working on another version of the device that works to deliver the drug in the form of solid powder through the skin by programming the vibrating device, thereby turning the powder into a "liquid" form. ' . In this form, drug powder can be transferred through the skin like in the case of liquid.

It is known that this new syringe will appear in the near future in the market. At that time, it is certain that there will be no fear of pain during the injection.
