This FDA-Approved Medical Syringe Fills Bullet Wounds in 20 Seconds


Xstat Rapid Hemostasis System – Designed to Control Haemorrhaging

Around 30 – 40% of civilian death from traumatic injury is due to haemorrhaging and 33 – 56% of them tend to die prior to reaching the hospital according to the United States Army Institute of Surgical Research.The best option of survival is to staunch the flow of blood as rapidly as possible. Hence a newly approved medical device has come up. The Xstat Rapid Hemostasis System is mainly a syringe filled with tiny sponges which is now made available to people. It has been designed to control haemorrhaging especially for bleeding which cannot be stopped with a tourniquet.

The sponge filled syringe tends to fill gunshot wounds within 20 seconds and the device which had been formerly limited to military use, has received approval for use on the general population in America. Recently the Food and Drug Administration had cleared the syringe which is designed to prevent the flow of blood from an open wound, for use on adult and adolescent citizens. The Xstat had been initially developed for use by the military, wherein the risk of traumatic injury and bullet wounds was higher than in the civilian population.

Sterile Sponges of Cellulose

It was earlier organized in 2014, though the FDA has now finished evaluating the device and has made it available for use by first responders in case of an accident, shooting or natural disaster. In the Xstat syringe there are 92 tablet-sized sterile sponges made up of cellulose which is intended to stop the bleeding in wounds that do not stop easily by any other means.

Bleeding can usually tend to be effectively slowed with simple tourniquet which restricts the flow of blood to the injury. However a bullet wound or any other deep injury would be difficult to close. In such a situation, the Xstat is inserted into the wound and activated to release the sponge wherein each sponge tends to have an x-ray marker so that doctors can ensure that they are all removed from the body later on.

The Verge reports that the syringe tends to work on wounds that cannot be stopped with the use of a tourniquet which is a compression tool developed to control haemorrhaging. These may be wounds in the groin or the armpit.

Control on Severe Life Threatening Bleeding

As per io9, the Xstat Rapid Hemostasis System tends to work by filling a wound with a group of sponges which tends to expand rapidly thereby blocking the flow of the blood and provides pressure cause the bleeding to stop. According to Dr William Maisel, acting director of the Office of Device Evaluation in the FDA’s Centre for Devices and Radiological Health had mentioned in a press release issued by RevMedX which manufactures the devices, that `when a product is developed for use in the battlefield it is usually intended to work in worst case scenario where advanced care would not be immediately available.

 It is exciting to see this technology transition in helping civilian first responders control some severe life threatening bleeding at the time of the trauma scene’. Each applicator tends to absorb around a pint of blood and works up to four hours which provides adequate time for the injured person to receive surgery for the wound.
