The invention relates to a medical device, a method of identifying a blood vessel and a method of manufacturing a blood vessel positioning system. A pressure-based vascular positioning system includes a pressure-based vascular locator device coupled to a needle or catheter. A pressure-based vascular locator device may include a proximal end having a gas-permeable membrane and first and second chambers. The first chamber and the second chamber may be separated by an interior wall. Each of the first and second chambers includes a proximal opening and a chamber opening having a pressure-enabled valve disposed therein. The pressure-based vascular locator device may further include a gas-permeable membrane configured to cover the proximal opening of the first chamber and the proximal opening of the second chamber. Each of the chambers includes a window that enables a user to observe the contents of each chamber. A method of identifying a blood vessel includes visually checking whether blood is present in each cham
