vacuum plaster to make wounds heal faster: hi-tech dressing sucks out dead tissue, bacteria and debris
The scientific dressing draws from the wound death tissue, bacteria and debris that may hinder the healing process and cause infection.
At the same time, vacuum action helps to encourage blood to flow into the wound, bring oxygen and immune cells, and speed up the healing process.
Many studies have shown that this technology
Called negative pressure wound therapyis effective.
However, the previous device was the battery-
Patients who need to be charged or powered from the power supply and often need to be hospitalized for a few weeks.
This new manual activation device is much smaller and lighter than its predecessor.
The disposable device, called Nanova, consists of a standard dressing, which is connected by a plastic pipe to a vacuum pump about the size of the phone.
The patient can activate it by holding it down with his hand.
This will create a vacuum in the pump for three days.
The vacuum pump is a pipe with a piston inside.
There is a hole at the end of the tube, there is-Valve inside.
When you push the piston down, the air is discharged through the valve, which prevents the air from returning to the pipe, resulting in a vacuum.
After three days, the patient pump out again and start the cycle again.
The disposable dressing currently available is 18 cm by 18 cm;
They have silicone edges to form a center layer of water absorption that seals and collects liquid.
Other negative pressure units need to be replaced after a week as they are full of scrap but Nanova can last for 30 days.
Then throw away the whole system including dressing and vacuum.
This treatment is suitable for all types of open wounds, but may be particularly useful for patients with chronic or infected wounds such as foot ulcers and pressure sore, as well as diabetes and multiple hardening --
Situations that may result in nerve damage and loss of sensation, so patients may not notice their injuries until they are infected.
In recent years, several devices have been available to help patients receive negative pressure wound treatment at home, but Nanova-from U. S.
Is the first to be activated manually.
Avance Solo, for example, is a vacuum device with a small can for collecting waste water taken out of the wound.
The other is called PICO, there is no tank, but the fluid is absorbed in the absorption layer inside the dressing.
But additional training is required for these electrical equipment to work, and new pumps are not required.
Recently approved for use in the UK, the device is now available on the NHS.
Dr Bav Shergill, dermatologist and surgeon at Queen Victoria Hospital NHS Foundation Trust, said: \"This is a new way to bring the benefits of vacuum pumps to wounds --
Treat the patient at home.
\"Chronic wounds cost the NHS a few poundds a year, so if it works and costs a lot, it could be a useful addition to traditional dressings --effective.
At the same time, new dressings made of horse tissue also help to speed up wound healing.
This plaster that looks like a standard dressing contains sterilized tissues extracted from the tendon of the horse, which are particularly rich in collagen.
This tough fiber material provides a stand to help the hardto-
Wounds heal faster.
In a trial at the Florida NFRMC wound treatment center, 20 patients with chronic leg ulcers will be injected with horse pastenamed bio-ConneKt -
Or a normal \"placebo\" plaster for up to six months.
Can be replaced as needed.
