Arthrogryposis: 3D printed exoskeleton

2012-08-15T18:32:00.000+01:00

3D printing technology is opening up a new branch in hospital sector. Developments in the current 3D printing technology is aiding to the realisation of personalised medicine. Now with this technology individual hospitals can be transformed into small scale manufacturing sector. One of the best example on the realisation of 3D printing in hospital sector is discussed on the video of Emma a toddler diagnosed with arthrogryposis (a congenital disease condition were the patient is unable to move arms without assistance). When exoskeleton for adults are struggling to be realised on commercial basis, 3D printing of exoskeleton on one to one basis for kids seems to be easily put into practise by a skilled biomedical engineer using CAD and 3D printer. There is a great prospects to this technology as scientist around the world are trying to find more and more materials that can be printed using a a 3D printer. One group of scientist from Cornell university are on the verge of 3D organ printing.

The complete implantation procedure of hearing aid is shown in the implantation procedure page of the blog.

Software to learn anatomy

2012-01-11T00:28:00.001+00:00

Biodigital is a web based application that helps to understand the anatomy of human body. Its software based on advanced HTML 5 and webGL technology, currently it performs well on certain browser as that are stable to an extent. Biodigital is a good platform for educating students from secondary school to even in professional medical or bioengineering studies.Virtual body is also a software that help in learning anatomy.
This software's can be easily installed by students for learning or physician to give a presentation.

Flowrest is an advanced device which can be used to deliver medicine requiring a specific humidity and temperature non invasive respiratory support. Design and working of each component of the device is described in the video below.

Care innovation connect

2012-01-10T23:54:00.000+00:00

Care innovation connect is a programme to remove the social isolation problems commonly seen among the elderly people. The software helps various care providing organisation to keep an eye on health of all the members by doing proper easy surveys, passing right informations and maintain alerts. This could evolve as a platform from which virtual consultation or telemedicine applications can be launched.

Robots for brain stem stroke patients.

2012-01-10T23:40:00.000+00:00

Brain stem stroke recovered patient or quadriplegic patient finds it very hard to do basic day today activities of life. One of the possible solution to this problem is by developing robots that can complement quadriplegic patient activities. Robots can be used to navigate around the room according to desire to keep an object at place, to do basic activities like reading newspaper, sending mails, shaving etc. Providing accurate interface robot quadriplegics is a tough technological challenge.In future Brain interfaces will overrule all the current interfaces based on eye movement, vocal command and touch.

Surgical smoke capture device

2012-01-10T23:17:00.000+00:00

Electro-surgical technique is a widely accepted tool for cutting, coagulation, dessicate tissue. On application of high frequency electric current on tissues, smoke containing traces of carcinogens, viruses, bacteria are produced. Since surgical rooms has only limited air circulation long exposure to this gas can result in respiratory problems to surgeons and operative room staff. Surgical smoke capture device can be easily deployed on the area of interest at ease.

Miniaturised diagnostic lab

2012-01-07T22:11:00.001+00:00

Lab on a chip or Miniaturised lab are new technological development in the field of cost effective diagnosis techniques that having same benchmark as that of conventional equipments. These development takes place as a result of advanced development in field of Molecular biology, Microchemistry, Nano materials, Microelectronics etc in the last decade. Cost effective diagnosis will continue to evolve as a large population in the world lives in remote area and due to the importance of better diagnosis in primary healthcare centre.

Non surgical artificial retinal device

2012-01-07T16:16:00.000+00:00

More than 10 million people around the world suffers from a retinal disease known as macular degeneration resulting in loss of eyesight. Macular tissues are found in the retina which plays a major role in identifying lights.
Treatment to this condition using drugs are effective to only a small fraction of population, but development in therapeutic devices for solving this problem looks promising. Device shown in the video is different from the current available devices that can just distinguish high contrast images. This device works by producing encoded signal that matches the signal produced by bipolar and amacrine cells to the neural network.

Exoskeleton - Mobility tool for paraplegics.

2011-12-14T09:11:00.003+00:00

Over the last 1500 years people who lost lower limb are using passive crutches and wheelchairs for mobility. Ever since advancements in robotic field, a new avenue is opened up to provide powered mobility option to paraplegic. Exoskeleton developed by esko comprise of 4 motors, 15 sensors and microprocessor which are used to sense environment and act accordingly to provide mobility. Miniaturising motors and battery with equivalent torque and current rating respectively could bring amazing commercial viability of this sort of products. Micro and nano electromechanical device development hold the future of exoskeleton. Video demonstrate study on powered exoskeleton.

Need for - Tuning of cochlear implants

2011-12-14T01:33:00.000+00:00

Cochlear implants are on of the most successfully implantable device that can restore hearing loss. But to the surprise still with most advanced hearing implants can't help a person to differentiate sound of musical instrument or enjoy every fine note that can be recognised by a person with normal hearing. Digital signal processing algorithms and real time sensor has to be improved to fill this gap, Dr charles of Johns hopkins institute demonstrate its significance in the video.

Solution for most undetected disorder: Sleep apnea

2011-12-02T02:01:00.001+00:00

Ideally its a condition described by physician were neurological simulators fail to excite muscles around tongue leading to airway block and thus the disturbing Hzzzzzzzz sound. Diagnosing these symptoms with accurate data set is a tough process. Conventionally to do this patient has to stay overnight in the lab, which itself lead to an error as its not the normal environment were subject takes normal sleep. Video on diagnosis describes a miniaturised device that can generate data accurately yo normal lab equipment and the treatment video shows a therapeutic solution to this disease using a electrical simulator.
