The cover body is concavely formed the recess of operation gripping in its position being connected with the guide cone guide part, described recessed
Enter portion excessive with the lower surface arc of the cover body；The guide cone be colored transparent resin guide cone, the guide part with
The color of other parts is different, and the cover body is translucent Cowhells rubber cover body；
The blood drawing ensures that the operation of device includes：Cuvette cartridge is fashionable to an angle is rotated in the cover body, makes test tube light
It is transferred to, while bending the convex top, then test tube is outwards gently pulled out, makes all raised bendings and flexibility adds
Greatly, larger frictional force is formed with test tube, to clamp test tube, test tube is withstood the power of blood drawing needle pierces；Conversely, work as will
When test tube is extracted, first to one, test tube gently to the power in the cover body, make raised lax, then outside Spin tubes are easily to take
Go out；
The processing of the blood drawing protection device is comprised the following steps：
Step one：Processing guide cone：Two different colors of resin raw material is loaded into conical die heating, the raw material of guide part color
The bottom in mould, by a kind of raw material wire drawing of upper color in mould into tapered, heats, in the original of another color of cone tip part again
Expect wire drawing into guide part；Solidification：One-step solidification, heating, is solidified by different colours cure profile of different shapes and parameter,
Mould is poured out, secondary solidification is carried out；Coloring：In the maximum upper table face colouring for guide cone, led in drop on the through hole of guide part
To the coating of portion's color, coloured to the inner surface in through hole for guide part through hole by way of blowing；Cure process；
Step 2：Processing cover body；The mould of upper and lower two cover body point mould is made, the cavity of mould is the interior institute together with projection of mask slot
There is space, placing dividing plate in raised edge is separated out cover body together with the cavity of bossing and the cavity of mask slot space segment；
Translucent Cowhells rubber raw materials with natural rubber as major ingredient, are put into during cover body is together with the cavity of bossing in mould, will make
The material for making silochrom allows in mould in the cavity of mask slot space segment, takes away dividing plate, matched moulds heating vulcanization, while shaking
It is dynamic；According to the temperature and state modulator of rubber-moulding in heating, while the vibration frequency of the shape according to rubber-moulding is carried out
Vibration, becomes sulfidization molding and becomes vibration, and elastomeric material is molded at a temperature of 140 DEG C~160 DEG C, now silochrom material also not into
Type；After elastomeric material shaping, the projection in mask slot is routed up in die sinking, takes out silochrom, now silochrom shaping is not enough and
Softer, in the outer surface of cover body, raised inclined direction is driven arranged side by side projection to the direction of original notch using numerically controlled lathe
Multi-blade carries out smart car to multiple tracks projection；
Step 3：Guide cone is installed on cover body.
3. it is according to claim 1 and 2 blood drawing protection device processing method, it is characterised in that：The blood drawing protection dress
The guide cone bus and the angle of axis put are in the range of 75 °~83 °, and the cone bottom surface external diameter of described guide cone the top is big
External diameter is in the range of 4.5 millimeters~8 millimeters at the maximum external diameter of the cover body, the minimum of the cover body.
