3) by pipeline communication, the end of threeway (D) one is connected to pressure sensor.Water level is identified into cylinder (E) with mobile clip to be fixed on
Higher than the position of urine kinematic analysis instrument pressure sensor, the butterfly valve (F) under water level mark cylinder is opened, is opened from water level mark cylinder
Mouthful medical two level pure water is injected, be allowed to full of measurement pipeline, discharged and block threeway (D) and pressure sensor with plug after bubble
Redundancy port, and disconnected and the connection of pressure sensor using the butterfly valve of threeway (D).
Vertical adjustment：In the case where expansion link is in fully compensated state, the upper and lower alignment (place of steel plate of upper and lower support (H-2, H-3) is confirmed
In a plane).After being completely stretched, weight (H-1) hangs on to upper bracket (H-2) opening position, regulating box pin screwing,
Make the gap of weight point alignment lower carriage (H-3), show expansion link perpendicular to horizontal plane during alignment.
With reference to the calibration of zero-bit：Water level mark collet chuck is held into (the B- on the outermost pull bar of telescoping tube with movable clip (G)
1), the height of adjustment mark cylinder, it (is preferably the shame of patient with reference to zero-bit to make its reference zero-bit substantially with urinating kinematic analysis instrument
At synostosis, but actual reference zero-bit is depending on installation site, generally urine kinematic analysis instrument by correction force snesor rubber
Glued membrane Nang centre-heights, or the handrail center height of collection urine closestool) quite.One section of 50cm or so flexible pipe one end is accessed
With leading directly to air by the redundancy port of correction force snesor, the other end, its end face forms spillwag chute, by spillwag chute and refers to zero-bit
Alignment.The butterfly valve of swivel tee (D), the present apparatus is established with pressure sensor and connect, mark cylinder water level and flexible pipe spillwag chute
Difference in height can cause the flowing of liquid in pipe, the height of appropriate regulation mark cylinder (water if necessary, need to be supplemented in time), make redundancy
During liquid level in the flexible pipe of port side (but in pipe water and do not spill over) concordant with its spilling plane, soft liquid in pipe is in static shape
State.It can be seen from hydrostatics principle, now identify concave meniscus lower edge in cylinder and be in same level (two liquid levels with spilling plane
Straight-through air, pressure differential zero).The sub- lower edge of collet chuck will be identified to align with concave meniscus lower edge in mark cylinder, if under pull bar clip
Height indicated by edge is xcm, and now, the hydraulic pressure that pressure sensor is born is the zero-bit pressure of reference bit.In this state
Under pressure sensor is returned to zero, realize the calibration of zero-bit.
The calibration of other pressure spots：Water level mark cylinder is handled with the mark collet chuck sub-folder of movable clip, and collet chuck will be identified
Sub- lower edge aligns with concave meniscus lower edge in water level mark cylinder；Pull bar clip is clamped in the top of each measurement pull bar respectively, this
When pull bar clip lower edge should be in close contact with measuring the top of pull bar, such as appreciable change occurs for the water level in water level mark cylinder
When, fine motion mark cylinder makes the sub- lower edge of mark collet chuck keep aliging with concave meniscus lower edge in water level mark cylinder；Pressure sensor is held
The hydraulic pressure received is respectively (50-x) cmH (relative to zero-bit pressure is referred to)2O、(100-x)cmH2O and (150-x) cmH2O。
This hydraulic devices urinates kinematic analysis instrument pressure measxurement using medical two level pure water as working media after being convenient to calibration
The cleaning of passage, reduce the probability of patient's infection, there is the advantages of accurate, simple to operate measurement, portable convenience, improve urine
Security, reliability and the operating efficiency of kinematic analysis instrument pressure calibration.
Device in the present invention, it is 4.90~19.61kPa (50~200cmH that can quickly produce pressure limit2O) hydraulic pressure
(limits of error are ± 1%), the calibration available for urine kinematic analysis instrument pressure parameter.
For the device illustrated in each embodiment of the present invention, within the spirit and principles of the invention, made
Any modification, equivalent substitution and improvements etc., should be included in the scope of the protection.
