AI Technical Summary
The number of blood collected in clinical trials has caused nurses to need to repeatedly contact the needle, which is at risk of being stabbed, and the prior art requires discarding 0.5 ml of blood to ensure the filling of normal saline.
A blood collection device for clinical trials is designed, including blood collection ducts, retention needles, base components, sealing parts, test tube support parts, snap-on components and blood collection test tubes. Through the installation of the test tube support, the blood collection test tube is connected to the blood collection duct to achieve needle-free blood collection, avoid the risk of stabbing, and save the patient's blood.
Needle-free blood collection is achieved, which avoids the risk of nurses being stabbed, saves patients' blood and avoids waste of blood.
