Capillary blood collecting device

A capillary blood collecting device, comprising:

• a fixing device including a first body and a second body pivotally connected, an accommodating cavity for accommodating a finger, for which blood-collection is to be performed, and a squeezing member for squeezing blood to a fingertip site, wherein the capillary blood collecting device is configured to detachably accommodate at least one skin puncture part on a side of the finger from which the blood-collection is to be performed, and the skin puncture part includes a blood lancet that is drivable to puncture the finger;
• a block member provided in the fixing device and away from the skin puncture part with respect to the squeezing member, so as to prevent blood in the finger from flowing back to a root of the finger upon pressurization by the squeezing member, the block member including a first block member disposed on the first body and a second block member disposed on the second body, the first block member and the second block member being disposed opposite to each other;
• and
• an actuating mechanism configured to actuate the first block member and the second block member first to clamp the root of the finger to pressurize the root of the finger, and then actuate the squeezing member to perform the squeezing.
