In some developing countries, when patients hemorrhage blood during childbirth, doctors use a ladle and cheesecloth to perform auto-transfusion — gathering and recycling blood for the same patient during a medical procedure. This DIY method is necessary because the machinery and supplies typically used for transfusions are so costly. Sisu Global Health designed Hemafuse, a handheld, mechanical device for intraoperative autotransfusion of blood collected from an internal hemorrhage, meant to replace or augment donor blood in emergency situations. The device is a semi-reusable device that can be used up to 50 times with one-time-use, disposable filters. In between uses, the main body of the device is sterilized. Hemafuse can be used in most situations of hemothorax and hemoperiteneum (including incidents of blunt trauma and early pregnancy complications) and exclusion criteria include threats of malignancy (cancer) or sepsis.
