Flexible, biodegradable and anti-microbial new advanced form of Intra Uterine Contraceptive Device (IUCD)

Three young engineers of the premier institute of IIT Kharagpur  Mr. Bhuvaneshwaran Subramanian, Selvakumar M & Dibyendu Gouri  developed a flexible, biodegradable and anti-microbial new, advanced form of Intrauterine Contraceptive Device (IUCD).
Intrauterine Contraceptive Device (IUCD) is a uterine implantable fertility-control device which prevents implantation of embryo but sometimes causes trauma, leading to cramps and microbial infection. Also, because of the fixed shape and size, it is not appropriate for anatomy of uterine cavity of every woman. Thus, a new form of IUCD, having controlled biodegradability, anti-microbial and radio-opaque properties, has been developed by them.

IUCD1

The IUCD developed , when introduced into the uterine cavity, adopts a shape that matches with that of the individual uterine cavity. At the same time its shape changes continuously in accordance with the uterine-cavity changes, though being resistant to spontaneous expulsion. It also has a hollow tube of segmented polyurethane (SPU) polymer, doped with Bismuth oxide, which is filled with spongy foam and grafted with aloevera and neem extracts which are non-toxic and destroy sperm cells. 

IUCD2

After implantation of this new form of IUCD, the flexible property helps accommodate inside the dynamic uterine environment and the biodegradable property minimises the rejection mechanism by the endom etrial tissues. SPU also releases antibiotic fragments which render the inner wall of the uterine cavity antimicrobial and protects the individual from sexually transmitted diseases. It solves the problem of cramps and perforation. The fertility can be restored after complete degradation of the new form of antimicrobial IUCD.

For this flexible ,biodegradable and a nti-microbial new advanced form of Intrauterine Contraceptive Device (IUCD) , they received Gandhian Young Technology Innovation Award 2016 organized by BIRAC-SRISTI at Rashtrapati Bhawan, New Delhi.

Device that monitors the vitals of mother and fetus during labor

Vichal, an Electronics engineer from Kodagu district, Karnataka has completed her M. Tech from BMS College of Engineering, Bangalore. Healthcare is always the cause she cared about the most, the reason being, it directly affects the lives of people. She always wanted to utilize her skills to contribute something to this field that will save millions of lives. That is the reason she chose to do her master’s in Biomedical Engineering. Since childhood, science has been my favorite subject and was very enthused in making science models and projects.

Vichal P M

As a part of her Master’s degree in Biomedical engineering, she began her field survey. She visited hospitals, spoke to gynecologists and understood the problems being faced during labor. She saw that there were around 20 mothers going through labor at the same time and comparatively very limited staff to keep monitoring their vitals which is supposed to be done at least on an hourly basis during the 8 to 12 hours duration of labor. When any complication or abnormalities happen in this duration, timely intervention is the key to save both the mother and fetus.

After learning about all this, she went through the WHO statistics of maternal and fetal mortality and to her surprise she found out that globally about 287,000 women died in 2010 of complications during pregnancy or childbirth and there were 2.6 million stillbirths globally with more than 8200 deaths a day. Majority of these cases happened in developing countries like India which made her realize that there is a huge necessity for an affordable device which will help in detecting abnormalities and notify so that immediate care and attention is given in order to reduce the mortality rate.

Vichal P M- Prototype

 Hence began her research on pregnancy, labor and childbirth. She collected as much  information she could gather from the internet, by talking to doctors and visiting  hospitals which helped me in the design and development of the device. The device  can be worn with help of a belt around the abdomen of the mother. It continuously  monitors the contractions happening, heart rate of the fetus and mother and also body  temperature of the mother. These parameters are important to be monitored during  labor and they are continuously displayed on the device itself. Any deviation from the  normal values in any of these parameters will indicate that there is some abnormality  and hence an alarm notifies the concerned personnel to immediately analyze the  problem and take action.

vichal P M- Award With support from my guide Dr. Manish Arora, Assistant professor Appaji M Abhishek  and  clinical inputs from Dr. Lavanya Kiran, the project is now in the stage of  prototype.  The aim is  to improve the prototype to a product so that it reaches the end  users and  helps in reducing  the maternal and fetal deaths caused during labor. By  the support  provided by BIRAC-SRISTI GYTI awards-2016, I’m hoping that I’ll make it  happen. If  successful, this device can be used in hospitals, Primary Health centers  and even at  homes. Also, midwives can carry it around during their visits. It does not  require any  expertise to operate, it will be affordable and an easily portable device.  The vital parameters being displayed on the screen (NC-Number of contractions,  DUR-Duration of each contraction, FHR- Fetal heart rate, MHR-Maternal Heart Rate, TEMP-Maternal body temperature)

Can titanium foam potentially substitute the bone grafts?

Two young researchers of the premier institute of IIT Kharagpur, Mr. Kausik Kapat and Mr. Pavan Kumar Srivas received Gandhian Young Technology Innovation Award 2016 organized by BIRAC-SRISTI at Rashtrapati Bhawan, New Delhi for developing simple cost-effective bone fracture healing promoter using porous metal plugs.

Kausik-Kapat

 

They developed a novel process for bioactive titanium foam which assists quick fixing of critical bone fracture. The foam also solves issues of implants loosening and post-implantation failure by strongly bonding with native bone.

 

Product prototype- Kausik Kapat

Thedeveloped process could be a platform technology forfabricating various dense, porous and graded implants for different load bearing applications like spinal shunt, cancellous bone, dental root, mandible or any other implants to address traumatic injury, skeletal degenerative diseases including osteoporosis.

The indigenously manufactured implants would potentially substitute the imported ones offering affordability to the common population of the country. This technological innovation was carried out at Biomaterials and Tissue Engineering Laboratory in School of Medical Science & Technology under the mentorship of Prof. SantanuDhara.
