Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright it is described in further detail.
Embodiment of the present invention provides and a kind of makes in the fluid infusion device for being administered patient
Fluid passage calibrating installation, this fluid passage calibrating installation can be used for calibrating various different fluid (example
As, can be to the various liquid that the patient of such as mankind, animal etc is administered, gas etc.) flow through stream
The flow of body passage, fluid passage is the pipeline closed.Wherein, flow flows through fluid in being the unit time
The Fluid Volume of the cross section of passage, Fluid Volume can calculate with volume.In some embodiments,
Fluid can include liquid medicine, such as, insulin etc..When the fluid of infusion is insulin,
The unit of flow can be unit/hour (unit/hour), wherein, unit/hour in unit and the changing of milliliter
Calculating ratio is 100:1, say, that 1 milliliter is 100 units.Fluid passage calibrating installation can include adjusting machine
Structure, this correcting mechanism has the part engaged with fluid passage, and this part can be at multiple positions and fluid
Channel engagement, for example, it is possible to arrival end in fluid passage, the port of export or at arrival end and the port of export
Between optional position engage or installation calibrating mechanism.The joint of correcting mechanism and fluid passage can also be adopted
With various ways, connect or the mode etc. that removably connects it is for instance possible to use fixing.Embodiment party of the present invention
The fluid passage that formula relates to is to can be used for the fluid passage that the pipeline aperture that is administered patient is less, it
Cross sectional shape can be circular, it is also possible to for other shapes easily fabricated in manufacturing process.Stream
The aperture of body passage be can be 1 μm to 200 μ m any one or more (such as, more than or
Equal to 2), such as, aperture can be 1 μm, 2 μm, 3 μm, 5 μm, 7 μm, 10 μm, 20 μm,
Any one or more in 30 μm, 50 μm, 100 μm, 150 μm, 200 μm.
Correcting mechanism can by via or flow through correcting mechanism fluid circulation area change come
Change the flow of the fluid flowed out from outlet flow channels end, for example, it is possible to reduce via correcting mechanism
The flow of the fluid that the circulation area of fluid flows out with the port of export reduced from fluid passage.Such as, right
During the flow of fluid detects in fluid passage, find that the flow of fluid is more than set in advance
Flow standard value, say, that in fluid passage the deviation of the flow of fluid and flow standard value be on the occasion of,
Can correspondingly be selected to reduce via the correcting mechanism of the circulation area of its fluid calibrate this on the occasion of
Deviation.
