According to foreign media reports, Swedish scientists have recently invented a new type of medical implantable hearing aid that can replace the middle ear to restore the normal hearing. Patients who have lost hearing can use this new implantable hearing aid instead of the middle ear to regain normal hearing. This unique device was developed by Chalmers University of Technology in Sweden and successfully applied to implant surgery.
The hearing aid is implanted under the skull of a patient less than six centimeters behind the ear. The use of the skull to transmit sound waves to the inner ear, the so-called bone conduction, successfully gave the patient access to hearing. The researchers said, "50% of the sound people hear is transmitted from the bones, so this sound sounds natural."
The figure can restore normal hearing by implanting a bone conduction hearing aid into the middle ear.
This new type of implantable hearing aid is called a bone conduction hearing aid. Unlike other hearing aids, this bone conduction hearing aid does not require a fixture, so there is no need to worry about losing some small parts or causing skin damage at the implant. infection.
This technique is used to treat patients who have lost hearing due to prolonged inflammation of the outer or middle ear, bone disease, or congenital external ear dysfunction. For these patients, bone conduction hearing aids work very well. In addition, this new implantable hearing aid can help some patients with inner ear injuries.
The researchers hope to get the results of the first clinical trial early this year. For the future of this technology, they said: "We plan to extend this technology to treat ordinary patients within one to two years. We are in this technology. The development phase requires a lot of investment to quickly apply new technologies."
Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
