Product Description
It
is often used in medicine, medical needle needle specifications
general points: normal wall, thin walled, ultra thin, rigid
performance and its sharpness directly affect the degree of the
patient's pain, countries in the GB - *********1 -
manufacturing
In
the standard of stainless steel needle tube for medical machine,
the rigid size of medical injection needle tube is specified, and
the production unit must be strictly implemented.
Principle
of needle tube rigid test method:
Measure
the deflection value of the needle tube by applying a specified
force to the center of the specified span of the supported
needle.
Technical
parameters:
Deflection
measurement range: **5mm accuracy + 0.*1mm.
Setting
load: 5.***0n accuracy + 0.1n.
Shelf
distance: ***5mm accuracy 0.5mm.
Needle
tube specifications:.3mm*3.4mm (normal wall, thin wall, ultrathin
wall)
Loading
speed: the accuracy of v=1mm/min is 0.1mm/min.
Dimensions:
**0mmx**0mmx**0mm.

Test
method:
Rigid-take
right amount of the separated and glass syringes, abandon rigid
test instrument [can pass the push rod to *0 N shi (precision is:
+ / - 0.1 N), the force vertically downward effect on the needle.
The lower end of the push rod
By
a mutual into *0 ° Angle of mode shape and curvature radius of
cylinder of LMM, the push rod width at least 5 mm, displacement
measurement precision of the instrument for muscle (see figure
1), the adjustment of the needle and just according to the
requirements of the following
Test
instrument: a) the span to be measured in table l needle
specifications corresponding numerical: b) made of push rod end
surface is located in the center of the span: c) makes the needle
with two needle be vertical and the push rod, the
same
The
center line of the needle tube and the center line of the shelf
are coincident. According to the span and load conditions
specified in table l, the test is carried out: according to the
corresponding force of the needle tube in table l, the speed of
lmmlmin is used to push the needle through the push
rod.
The
pipe bending force is applied downward to measure and record the
deflection of the needle tube at the force point, to 0.*1mm. The
injection needle should have good rigidity, and the large
deflection should meet the requirements of table l.
Test
procedure:
1.
Place the needle tube on the rigid test instrument and adjust the
needle tube and the rigid test instrument as
follows:
Make
the span to be the corresponding value in table 2.
The
end of the push rod is at the center of the span;
Keep
the needle tube perpendicular to the two holding posts and the
push rod, and align the center line of the needle tube with the
center line of the shelf.
2.
The force that corresponds to the nominal specification of the
syringe in table 2 is used to apply bending force to the needle
tube at a rate of 1mm/min.
3.
Measure and record the deflection of the needle tube at the force
point to 0.*1mm.
