Hold blood for 15 seconds with a sponge syringe

To limit the risk of death due to excessive blood loss, RevMedX company in Oregon (USA) has developed an effective effective hemostatic method, especially the wound due to the bullet on the battlefield which is cause of 80% of deaths among wounded soldiers.

According to RevMedX, the device called XStat is an improved syringe containing tiny sponges. When injected into the wound, they hatch and cover the wound's mouth and stop bleeding for only 15 seconds. According to American medical doctor and designer John Steinbaugh, his team initially experimented by spraying foam into the wound. Although the blood stops flowing, the blood pressure of the injured is too high, causing the sponge to quickly drift away. They then decided to use sponges of the size of a small pill made from wood pulp coated with anticoagulant and antimicrobial chitosan.

Manufacturers said that the ambulance soldiers on the battlefield could easily use Xstat, by inserting a syringe into the wound's mouth and pressing the plunger to inject sponges. In addition, each sponge is marked with an "X" visible on the X-ray film to ensure they are not stored in the body.

After an animal test showed that the sponge had a rapid hemostatic effect, the team was funded by the US military for $ 5 million to complete the product. RevMedX is currently waiting for the US Food and Drug Administration (FDA) to authorize product circulation. It is known that RevMedx is also developing syringes with 3 different sizes to treat many types of wounds and it is expected that each syringe will cost about 100 USD.
