Product structure And Composition
The heel blood collection device is composed of a shell, a spring,
a blade and elastic parts; the shell and elastic parts are made of
acrylonitrile-butadiene-benzodiene (ABS); the spring is made of
carbon spring steel wire; the blade is made of stainless steel
production
Product Performance
- The appearance of the heel blood collector should be clean, free of
obvious burrs, stains and defects and other injection defects; the
blade should not have defects such as burrs and hooks.

fits without obvious misalignment.
- The surface hardness of the blade is not less than 350HV10; the
surface roughness Ra value of the blade is not more than 0.4μm.
- The corrosion resistance of the blade of the heel blood collection
device should reach level b (corrosion marks can be removed by
wiping).
- The blade of the heel blood collector can be retracted after use,
and the blade is in the housing.

Usage Method
1. Put the baby on his back, clean the area where the blood is to
be collected with a sterile cotton pad, and let it dry naturally,
and do not touch the sterilized area.
2. Remove the outer packaging of the blood sampling device. Do not
place the blood sampling device in an unsterilized place. Remove
the safety buckle of the blood sampling device. Do not push the
launch button or touch the blade.
3. Raise the baby's feet to a position higher than his heart,
choose a safe blood collection position according to the "Schematic
Diagram of Infant Blood Collection", and align the blood collection
port of the blood collection device vertically at the blood
collection site.
4. When the flat end of the blood sampling port is in light contact
with the skin, press the launch button to collect blood, and
quickly move the blood sampling device to the blood collection
site.
5. Gently wipe off the first drop of blood with dry sterile gauze.
6.1 Appropriate light pressure, use the blood sample collection
tube to collect an appropriate amount of blood sample, after the
blood collection, use dry sterile gauze to lightly press the
incision to stop the bleeding and prevent hematoma.
6.2 Appropriate light pressure, drop the blood directly on the
blood carrier card for sampling, and collect at least 3 blood spots
in a row. After blood sampling, use dry sterile gauze to lightly
press the incision to stop the bleeding and prevent hematoma.
Contraindication
1. Unless absolutely necessary, do not use it for infants
(including fever).
2. Do not collect blood samples repeatedly at the same location.
3. Do not use for infants with swelling, infection or inflammation
at the puncture site.
4. Do not use for infants and young children whose puncture site is
damaged by skin diseases or skin.
5. Avoid selecting the skin that has been sampled and within 2mm of
the sampling point as the blood sampling location.
Matters Needing Attention
1. If the safety buckle of the blood collection device is lost or
broken, do not use it.
2. The blood collection device is for one-time use, please replace
with a new blood collection device every time you collect blood.
3. The safe area for infants and young children to take blood
samples is to draw a line parallel to the side of the foot from the
middle of the fourth toe and a line parallel to the side of the
foot from the big toe.
4. When disinfecting the blood collection site, the disinfection
diameter should be more than 2cm.
5. Underdeveloped blood vessels may cause insufficient blood flow.
6. If the heel needs to be warmed up, 42°C-44°C is beneficial to
promote blood flow, but over 44°C will cause burns.
7. The blood collection device should be close to the blood
collection site and the needle should be inserted vertically, but
not too hard, so as not to cause a deeper and harmful wound depth.
8. When using the blood collection device, be alert at all times to
avoid accidentally injuring yourself and others.
9. After blood collection, you must pay attention to the place
where the blood is taken to prevent recurring bleeding or
inflammation.
10. The blood collection device is sterilized by irradiation, and
the validity period is 3 years. If it exceeds the validity period,
it is strictly prohibited to use it.
11. The blood sampling device after use may be contagious and
cannot be discarded at will to prevent pollution and injury
Keep In Storage
It should be stored in an environment where the relative humidity
does not exceed 80%, the temperature does not exceed 45°C, and
there is no corrosive gas, in a cool, dry, well-ventilated, and
clean environment.
