Description
Technical field
The present invention relates to fitting of medical apparatus and medical instruments field, more particularly to a kind of portion as speed governing groove
Part.
Background technology
Speed-regulating part in current infusion regulator is provided with one or more than one speed governing grooves, connects equipped with cross-sectional area
The speed governing groove of continuous change；Or the speed governing groove equipped with sectional type varying cross-section product.Because clinical transfusion is to infusion regulator
Adjusting speed accuracy require very high, and adjusting speed accuracy is often depending on the cross-sectional area precision of speed governing groove, especially in fine flow
When measuring speed governing, the cross-sectional area of speed governing groove with μm2As measurement unit.
Most speed governing groove is designed using open groove absolutely, to pull unhardened modeling when avoiding withdrawing pattern after being molded
Expect and cause speed governing face uneven, injection mold needs to set the inclination angle of low-angle, and speed governing groove generally forms after injection
The cell body opening width of speed governing groove is more than the slot bottom width of same plumb cut, generally inverted trapezoidal, semicircle.
But above-mentioned speed-regulating part is substantially produced by being molded after manufacture mould, because mould in process of production
Precision, die wear degree, identical material and physicochemical property, the production technology of different batches（As injection temperature, mold temperature,
Injection pressure, injection speed etc.）Etc. the precision of speed governing groove can be had an impact.Often there is 5~20 μm of error, very
It is very high in fine flow speed governing groove segment, error rate to higher.In existing transfusion speed regulator, in fine flow speed governing, adjust
Fast error generally reaches more than 10%, and most finished product error reaches 15~30%, part finished product error be even more than 30% with
On, even in, often there is also the unstable situation of quality, causing potential safety hazard with a batch of finished product.Especially declined in heart
Exhaust, kidney failure etc. to entering the very sensitive patient of liquid measure or need to precisely input the patient of salvage drug, easily cause medical thing
Therefore or even jeopardize patients ' lives.
On the other hand, because needing to be applied to the sealing gasket of various material matter in most infusion regulator, and sealing gasket exists
Deformation occurs after compression, protrudes into open speed governing groove, changes the actual cross-sectional area of speed governing groove.At continuous same angle
Degree or concentric are open, and sealing gasket can be allowed to be more easy to protrude into groove.Especially in the larger speed governing groove segment of flow velocity, open groove
Opening it is bigger, influence it is bigger.
Because transfusion precision does not meet clinical expection, and calculate into liquid measure it is to be easier to the side of implementation at present by determining drop speed
Method, therefore clinically still dripped with regulation based on fast common transfusion adjuster.
