As shown in Figure 1-3, blood collection auxiliary device includes half sole fixed plate 1 and the forearm that is flexibly connected with half sole fixed plate 1
Supporting plate 2, the upper surface of the two are provided with arc groove, and shape is consistent with palm and/or arm, meets ergonomics
Theory, half sole fixed plate 1 and be provided with empty slot on the side wall of forearm supporting plate 2, be provided on empty slot it is telescopic about
Band, half sole restraint strap 11 pass through fixed plate empty slot 12, and forearm restraint strap 21 passes through supporting plate empty slot 22, takes a blood sample for convenience,
It is provided with slack adjuster on restraint strap, unclamps restraint strap, when the palm of gathered person and/or arm are put into, adjust about
The slack adjuster of band makes palm and/or arm fixation, consequently facilitating finding radial artery, smoothly completes blood collection.Pine
Tight regulating device can be a flat bandage, one end of which is fixed on one of empty slot, and pass through corresponding another
A empty slot realizes the length adjustment of bandage then by tightening button, and one can also be arranged on empty slot and elastic stretch tight
Band draws high bandage, when the palm of gathered person and/or arm are put into, unclamp bandage, springs back bandage, to realize fixation
The palm and/or arm of gathered person, is also possible to other embodiment, if can elastic adjusting realize and fix, in this reality
With in novel protection scope.
It half sole fixed plate 1 and is pivotally connected with forearm supporting plate 2 by rotating device 3, specifically, being leaned in half sole fixed plate 1
Nearby the bottom of the side of arm supporting plate 2 is provided with axis hole, and rotation axis 31 sequentially passes through the axis hole of two sides, and with half sole fixed plate
1 is fixedly connected, and guarantees to be not in relatively rotate between rotation axis 31 and half sole fixed plate 1, can by being welded and fixed, or
Position limiting structure is set between rotation axis 31 and palm fixed plate 1, after rotation axis 31 passes through axis hole, the detent in rotation axis is stretched
Enter in the card slot in palm fixed plate, realizes and be engaged by clamping.
Arm supporting plate 2 is provided with first axle fixing clamp 32 and the second axis fixing clamp 33 close to the side of palm fixed plate,
The side of arm supporting plate 2 is provided with fixed plate 42, and fixed block 41 is mounted in fixed plate 42.Through-hole is provided on fixed block 41
43, in order to realize the rotation of palm fixed plate 1, rotation axis sequentially pass through fixed block 41, fixed plate 42, first axle fixing clamp 32,
Axis hole and the second axis fixing clamp 33, the diameter of through-hole 43 is slightly larger than the diameter of rotation axis, to make palm fixed plate 1 can be around rotation
The axis rotation of axis 31 forms angle between palm fixed plate 1 and arm supporting plate 2, to adapt to different gathered persons, in order to

41 clamping rotation axis 31 of block, rotation axis 31 cannot rotate in through-hole 43.
As illustrated in figures 4-5, blood collection auxiliary device provided by the utility model, in the specific implementation process, there are two types of different
Working condition.
Working condition 1: by the half sole restraint strap 11, forearm restraint strap 21 fixation after, palm and forearm are because of dorsiflexion
Radian is formed, keeps radial artery trend straight, beating point does not change after measuring.If the blood vessel on arm can be convenient at this time
It finds, does not need to adjust blood collection auxiliary device provided by the utility model under this state.
Working condition 2: the utility model under this state is to adjust the state shown after half sole fixed plate.Due to everyone
Vessel position it is not exactly the same, some people needs to use the adjusting machine of the utility model when radial artery is drawn blood
Structure assists finding radial artery.The step of adjusting are as follows: palm and arm are placed on blood collection auxiliary device by a., are passed through respectively about
Band is fixed；B. fixed mechanism handle 44 is unclamped；C. half sole fixed plate 1 is adjusted, palm and forearm radian form radian；D. manually
The mechanism that is locked handle 44.
By check experiment, in 20 crowds, because radial artery moves towards appearance 10 changed caused by unlocked dorsiflexion angle,
Appearance 10 of beating point change.After fixing dorsiflexion angle under equivalent assay conditions, radial artery moves towards appearance 1 changed, and fights
Dynamic point, which changes, not to be occurred.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
