This blood sampling collection from heel device working principle that blood was collected are as follows:
For this blood sampling collection from heel device under to cock, the key 2 is in rear working position, the top surface of hook platform 2 52 with it is described
The top surface of locating notch 41-2 abuts；The strip cylinder 13-2a of the guide post 13-2 is sleeved on the straight guiding hole portion 41-
In 6a-1；The blade 42 is in rear working position；Go out the edge of a knife 11 described in blade face；
When blood was collected, outlet is first imposed into downward pressing force to the portion 21 that presses of key 2 against blood sampling site is needed
F, key 2 is surrounded to be rotated clockwise with zygostyle 22-3, and spring 3 is further compressed；Key 2 is in the case where continuing stress condition, inclined-plane
One 22-2 is in contact with two 51-1 of inclined-plane, and the key 2, which is surrounded, is rotated clockwise to preceding working position with zygostyle 22-3, is driven item 5
When clockwise bending deformation reaches a certain level, one 22-2 of inclined-plane and two 51-1 of inclined-plane disengaging, hook platform 1 and hook portion 22-1
Formation is engaged, while positioning surface 41-3 is also detached from hook platform 2 52, control of the knife rest 41 departing from transmission item 5；Knife at this time
Frame 41 is mobile to 11 direction of the edge of a knife out under the elastic force effect of spring 3, and knife rest 41 moves forward to circle guiding hole portion 41-6a-2 and leads
It is engaged to limited post formation；Blade shifts to out the edge of a knife 11, until guide post 13-2 is oriented to hole portion 41-6a- completely into circle
Knife rest 41 cannot move still further below when 2, i.e., blade determines the piercing depth of heel；Spring 3 does not reach still freely at this time
Length, knife rest 41 is rotated counterclockwise by the cylindrical body 13-2b that elastic force effect begins around guide post 13-2, to make knife rest 41
Motion profile arc is become from straight line, while the inner wall sliding of the arcuately bent plate of spring 3, when spring 3 slides to arc bent plate
When the 41-5 of side block side, blade, which retracts in shell 1, deviates from 11 position of the edge of a knife, completes blood sampling movement.
The Blood collection of this fixed point sliding ensure that by the depth and size of blood sampling site wound, will not bring to patient
It is unexpected that pain also can satisfy the amount of test blood night expected from medical staff.It is to be noted that completed until blood sampling acts,
Spring 3 does not reach drift still, to guarantee that knife rest 41 is persistently made by elastic force without opposite direction movement occurs
Blade exposes again, causes to accidentally injure.In triggering, with hook portion 22-1 once being clamped will not reset, this is also avoided hook platform 1
The possibility that key 2 and transmission item 5 reset；It is disposable blood taking device use this guarantees the blood sampling collection from heel device of the utility model
Product will not be reused.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
Embodiment should not be considered as limiting the scope of the present invention.It is made according to the scope of application of this utility model equal
Deng variation and improvement etc., should all still return within the patent covering scope of the utility model.
