Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable foot blood sampling device for newborns. Background Art

[0002] At present, medical institutions generally use lancets to draw blood during routine blood collection. Although this method allows one person to draw blood with one needle and avoid cross infection, patients directly see the needle and develop fear (especially children); another method is to use the lancet with a lancet pen, install the lancet in the lancet pen, remove the lancet after the needle is injected, and install another lancet for reuse. Since the lancet pen is reused countless times, it is very easy to cause cross infection. Therefore, how to effectively avoid the shortcomings of existing blood collection devices and ensure safety and eliminate hidden dangers is a technical problem that needs to be solved urgently by existing blood collection devices.
