Modern medicine would be impossible without many plastic medical products that we take for granted. Did you go to the hospital? Plastic is everywhere, from gloves to sterile syringes, from venous blood bags to viscous bandages for IV tubes or heart valves. Plastic packaging is especially suitable for medical applications. Because of its excellent barrier performance, it can safely prevent pollution. Innovations in plastics are making new procedures possible. Imagine artificial plastic hearts, antimicrobial plastics or body parts, tailored to the needs of patients and printed on a 3D printer.
Reoval of blocked vessels
In ** heart surgery, small tubes (catheters) are used to open blood vessels, and deposits that block them can be broken down by a tiny spiral implant, a vascular stent. It is located in the treated arteries, made of plastics specially developed for the medical field, and contains active substances.
prosthesis
Plastics are now used as plastic surgery equipment, where they align, support or correct deformities. They can even improve the function of the body's active parts or replace the body parts to take over their main functions. Synthetic materials also play a vital role in diseased arteries that cannot be helped by vascular support. The affected aorta was removed and the gap was bridged with a flexible plastic prosthesis. Because of this, the lifeline of the body once again plays its full role.
Artificial cornea
Eye injuries or chronic inflammation, such as corneal erosion, can damage vision. If the chance of successful transplantation is small, prosthetic limbs are the hope. Artificial corneas made of special silicone resin are now available for treatment. Thickness is only 0.3 to 0.5 mm. It is highly transparent, flexible and biomechanically similar to natural cornea. It can restore clear vision again.
Deaf-aid
People with severely impaired hearing can now use plastic implants to normalize the sound they hear. The implant consists of many components - a microphone, a transmission device connected to a computer worn on the body, a stimulator and an electrode carrier with 16 electrodes for 16 different frequency ranges. When it converts sound pulses into electrical pulses, it bypasses the damaged cells and directly stimulates the auditory nerves.
Plastic pill capsules
Plastic pill capsules release appropriate doses of active ingredients at appropriate time. Polymers based on tartaric acid decompose gradually and release active ingredients slowly over a long period of time. These customized medicines help to avoid taking large amounts of tablets regularly.
