New Bio-polymer Micro-needle by BITS Pilani || Painless Injection


in medical care an injection is the
fastest way to introduced medication be it a drug vaccine or other therapeutic
agents into the body using a needle and syringe injections are amongst the most
common healthcare procedures in the world naturally it’s imperative that
injections are injected safely so that they do not harm the patient or expose
healthcare workers to unnecessary risks added to this is the fear and anxiety
that patients especially children face when they are given an injection with
the help of recent advancements in precision engineering researchers from
Hyderabad based BITS Pilani campus have successfully designed by a polymer-based
micro needle devices for vaccine delivery and for cosmetic applications
the needle of a of a syringe that we use for subcutaneous injection is about 1.5
centimeters in length so we are talking about reducing the size of the needle
anywhere from 20 to 30 times by using in the form of micro needles these
needles can be applied as a patch on the skin right and then we wear them for
anywhere from a minute to up to so many hours so that the drug from the needles
can be diffused into the tissue Dr. Venkatam RamShree Krishna and his team of
researchers started exploring better options for injecting medicines and
vaccines which can be painlessly injected using new materials which are
also degradable another reason for finding alternative degradable materials
in place of conventional injections are problems associated with the disposal
and the huge environmental costs they carry the team has successfully made
micro needles using bio polymer called zine which is found in corn and has been
used in manufacturing of biodegradable plastics fibers cosmetics textiles and
is also considered save for pharmaceutical applications microneedle based devices have been
found stable and effective for injecting several injections vaccines and also for
cosmetic treatments perhaps the biggest advantage is the microneedle patch patch
refers to a device with several bio polymeric needles coated with the
medicine ready to be injected once a patch or a sticker is fixed on the body
the coated drug starts diffusing into the skin slowly as compared with the
normal syringe these needles do not cause much injury and are minimally
invasive the initiative by dr. Venkat Vamsi Krishna to find alternatives to
the conventional syringes using bio polymers is indeed praiseworthy and will
go a long way in alleviating the pain that children as well as adults face
when getting injections
