Impact of Medical Technology Advancement on Human Civilization

Filed under: 2014 — Tags: — Winson @ 7:16 AM

Medical technology involves the procedures, equipments and processes through which medical care is delivered to the patient. Medical technology is an advanced technology and has an impact on human civilization. Advances in the medical technology improves the treatment with decreasing the risk. The advancement in the medical technology reduces the errors and protects the patient’s life.

The advancement of medical technology includes, advanced techniques, advanced equipments and discovery of new medicines.

Advanced techniques: Technological advancement in medical care plays an important role to save patient’s life.

  • Sensor and wearable technology: Sensor and wearable devices are used to collect the patient data. These sensors are placed on the patients body. These sensors acts as an alarm which sends information to the health care provider. It sends information when a patient fall down from bed, it also gives information if any infection occurs at the site of surgery. This decreases the failure of surgeries and decreases the risk after treatment.
  • Telemedicine: Telemedicine uses telecommunication or IT to get medical health care even though we are far. Most of the rural areas do not get all the services provided in the metropolitan cities, telemedicine helps them in emergency cases. Patients in ICU containing telehealth services are recovered faster than patients in normal ICU.
  • Pharmacogenomics: It is the study of genetic variations in response to drugs. Tailoring treatment plans to individuals and anticipating the onset of certain diseases offers promising benefits for healthcare efficiency and diagnostic accuracy. Pharmacogenomics helps to reduce the excess healthcare spending due to adverse drug events, misdiagnoses and other unnecessary costs.

Medical equipments: Advancement of medical equipments like diagnosis and surgical equipments reduces the risks and treat the diseases without any risk or failure.

  • In older days, neonatal deaths were more due to lack of equipment to diagnose and treat diseases. Now a days advancement in the medical equipments increases the child birth rates. Medical equipments include special ventilators and artificial pulmonary surfactants to treat lungs and breathing problems in infants. These advanced equipments saves the infant’s life.
  • Another advanced technology in case of heart attacks. In olden days, most of the people die if heart attack occurs. Later, Lidocaine was used to treat arrhythmia condition of heart and later by pass surgery to treat heart attacks.
    Later angioplasty was used to treat revascularization along with stems to open the closed valves. Now a days, better diagnostic equipments have come that detects the abnormal heart beat and drug eluting stents.

By use of advanced equipments, patients life is improved without any risk and the mortality rate was decreased from the past decades.

Discovery of new medicines: Medicines also play an important role in the treatment of diseases. In olden days, there is no medicine for some diseases like cancer and HIV. Now a days new medicines are developed to treat in early stages and control or relieve from symptoms of disease in advanced stages.

Types of Airbags and How an Airbag Works

Filed under: 2014 — Tags: — Winson @ 7:31 AM

An airbag is a safety device that protects the passenger in the event of a collision, by restricting their movement and inducing a slow reduction of the body’s momentum as opposed to coming to an abrupt halt. The greatest thing about an air bag is that along with the seat belt, it can reduce death in a collision by about 30%.

How does an airbag help in safety?
During a collision, the body of the passenger would continue to move forward, even if the vehicle has come to a sudden halt. This is because of the momentum carried by the body. So, in a collision, the upper part of the body hits the steering wheel or the dashboard hard causing fatal injuries or death. In high speeds, the passenger’s head even collides with the wind shield. This is extremely dangerous.

An airbag prevents the passenger from being thrown toward the dashboard. It also slows down the process of the body’s motion coming to zero velocity.

How is an airbag deployed?
There are collision detectors installed along with the airbags. When a collision happens, these sensors detect it, and send the signal to the airbag. In the airbag, this signal triggers a reaction between sodium azide and potassium nitrate. This reaction releases nitrogen gas which inflates the air bag. All of this happens under a fraction of a second and after the deployment, the nitrogen gas escapes through holes in the airbag to cause deflation in order for the passenger to move.

Different types of airbags

Frontal airbag
Frontal air bags are designed to prevent occupants from anything that is at the front portion of the car, like dashboard, steering wheel or wind shield. Since 1998, frontal airbags have been a standard in all the vehicles. Frontal airbags do not eliminate the need for seat belts. And they also do not protect the passenger in rear collision or a rollover. The amount of protection an airbag can offer depends a lot on whether the seat belt is fastened or not. Seat belts keep the passenger in the proper position to ensure protection by the airbag. An important thing to keep in mind is, if the seat belt is not on while in a collision, airbags can cause fatal injuries to the passenger.

Side torso airbag
This protects the passenger from injury to the ribcage and the pelvis. This airbags deploys in between the passenger and the door. Special designs are being included recently and these protect the passenger even in a roll over crash.

Side curtain airbag
The side curtain airbag deploys from the roof and protects the passenger from rollover injuries. Roll sensing side curtain bags are usually used in SUVs and pickup trucks because they are prone to rollovers. But in case the driver in taking the vehicle off road, he can disable the feature.

Knee airbag
This airbag is meant to protect the knees since the knee too is highly exposed while in a collision. These airbags deploy just below the steering wheel. The knee airbag has been increasingly used in cars since 2000.

Seat cushion airbag
The seat cushion airbag prevents the pelvis from diving below the lap belt in a collision.

Center airbag
This is meant to protect the rear passengers from head injuries. It deploys from the rear center seat. In 2012, General Motors introduced a center airbag which deploys from the driver seat.

Seat belt airbag
This is actually a seat belt that can be used like any other seat belt. But in a collision, the seat belt inflates and offers extra protection.

Pedestrian airbag
Pedestrian airbags are different in that they protect the pedestrian as opposed to the passengers. It was introduced in Volvo V40 in 2012 and it deploys from the car bonnet, so that the impact of the car on the pedestrian’s body is reduced.

The Working of a Hydraulic Braking System

Filed under: 2014 — Tags: — Ralph C Dreher @ 7:17 AM

A hydraulic brake system is one that uses brake fluid to transfer pressure to the wheels. In this system, when the brake pedal is pressed, force is exerted on the push rod, which in turn pressurizes the brake fluid, which pushes the pads against the rotor disc to stop the vehicle. A hydraulic braking system has the following parts.

  • Master cylinder
    This consists of a cylinder filled with brake fluid, a brake fluid reservoir, one or two pistons, ports from the main cylinder to the brake fluid reservoir and a return spring. The master cylinder receives pressure from the brake lever and conveys it to the hydraulic lines that start from it.
  • Wheel cylinder
    Similar to the master cylinder, the wheel cylinder receives pressure from the brake fluid and pushes the brake caliper pistons against the disc.
  • Brake fluid (or brake oil) pipelines
    These pipelines carry the brake fluid and connect the master cylinder to the wheels cylinder in each wheel.
  • Caliper assembly
    The caliper assembly contains the brake caliper pistons and the rotor disc. The caliper assembly is the component which is actually involved in the process of slowing down the wheel.

Working
When the brake pedal is pressed, the push rod presses the master cylinder’s piston. The piston pressurizes the brake fluid in the cylinder. The fluid moves through the pipelines and reaches the caliper assembly. At the caliper assembly, there are two pistons one on each side of the rotor disc and they are connected to the brake fluid. The brake fluid pressurizes each of the pistons from both the sides, and pushes them towards the rotor disc. Since there is a one way movement of the brake fluid due to the pressure from the brake lever, it is displaced in the brake fluid reservoir. This process leads to a frictional motion between the brake calipers and the rotor disc, and thus braking happens. And when the brake lever is released, the return spring in the master cylinder pushes the master piston to its original position and the displaced brake fluid returns back to the pipelines.

Brake fade
Brake fading is a common disadvantage of the hydraulic braking system. It is caused due to the following reasons:

  • When hydraulic brakes are subjected to heavy work like descending down a steep inclination, they produce a lot of heat. This might, in extreme conditions, vaporize the braking fluid. This causes ineffective or weak pressure in the caliper assembly and thus faded braking.
  • Due to continuous usage, the pads which cause friction over the rotor disc may become soft due to wearing. This also causes ineffective braking. It thus becomes important to check the brake pads regularly, and if necessary, replace it.
