Microneedle bandage to stop bleeding

2023: Product Announcement

At the end of January 2023, the University of Pennsylvania (USA) presented a bandage with microneedles, which can quickly stop bleeding. The device received an array of biodegradable and biocompatible microneedles made using gelatin-methacryloyl biomaterial.

Microneedle bandage to stop bleeding

The device contains silicate nanoplates, which give it hemostatic properties, and the structure of the needles increases the surface area for contact with blood and helps to bind the dressing to damaged tissue. Uncontrolled bleeding after traumatic injury at the beginning of 2023 is the main cause of death of young people, so the development of new medical technologies that can quickly stop bleeding. A ready-to-use hemostatic bandage will be a particularly useful component in first aid kits or military field kits as a first line of defense against such situations.

According to researcher Amir Sheikha from Pennsylvania State University, with bleeding injuries, it is often the loss of blood, and not the injury itself, that is the cause of death. There is an unmet medical need for ready-to-use biomaterials that promote rapid blood clotting. The sheikh also added that excessive bleeding is a serious problem for human health for 2023, and the developed arrays of microneedles reduced the time of blood clotting from 11.5 minutes to 1.3 minutes. These 10 minutes can be the difference between life and death for patients.

At the end of January 2023, the researchers tested the bandage on a rat liver bleeding model, where it performed well and reduced bleeding by about 92% compared to the untreated control group. The bandage also outperformed commercial hemostat in reducing bleeding.^[1]
