Description
Technical field
This utility model belongs to armarium, is specifically related to the high pressure injector with pressure detecting function.
Background technology
High pressure injector is one of device to be used in armarium, for by contrast agent, saline it
The liquid of class injects human body, is used for strengthening the effect of medical imaging, such as enhancing X-ray or magnetography
Effect.
At present, the major technique of detection high pressure injector pressure is for being injected part (example by machine internal detection syringe
As being positioned at the piston within syringe) pressure thus be transferred to machine internal sensor through bearing portions, reach
The effect of feedback injection pressure.It is to say, pressure transducer is arranged in high pressure injector by prior art,
To detect the load pressure of syringe inner carrier, thus optionally adjust the rotating speed of motor.Bearing of syringe inner carrier
Carry the injection pressure of pressure and human body, although both exist certain relation, but be not meant to that both are
With, thus there is certain defect in existing this kind of technology, i.e. examined the feedback regulation function of injection pressure
The pressure data surveyed is the most accurate.
Utility model content
This utility model is in order to solve the above-mentioned technical problem existing for prior art, it is provided that have pressure detecting
The high pressure injector of function, this technical scheme, by detecting the injection pressure of high pressure injector syringe needle side, is come anti-
The rotating speed of feedback regulation motor, thus reach more accurately to adjust the purpose of human injection's pressure.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that have pressure detecting merit
The high pressure injector of energy, including syringe, piston, motor, control circuit, pressure transducer and holding wire,
Piston is arranged in syringe, and pressure transducer is arranged on the needle end of syringe, and pressure transducer passes through holding wire
Electrically connecting with control circuit, motor electrically connects with control circuit；Pressure transducer is at the syringe needle of high pressure injector
End gathers the injection pressure of human body, and by holding wire output detections result to control circuit, control circuit root
Testing result according to pressure transducer controls the rotating speed of motor, thus regulates high pressure injector.
Preferably, described holding wire is and the structure of integrated pressure sensors formula；Described holding wire can also be
Pluggable structure.
Preferably, described pressure transducer removably connects with syringe；Described pressure transducer can also and pin
Cylinder is one-body molded.
Principle of the present utility model is: one end of high pressure injector syringe is connected with high pressure injector, the other end
(i.e. that one end of syringe needle) is connected with pressure transducer, when patient is at injecting fluid, such as during contrast agent, and pressure
The force value of force sensor measuring patient positions also is sent to be positioned at high pressure injector machine by holding wire in real time
Internal control circuit, is analyzed current pressure values by control circuit and processes, when force value exceedes pre-
If limit value time, then stop motor, thus protect the safety of patient to greatest extent.
Compared with prior art, this utility model have the advantages that high pressure injector syringe needle that
End arranges pressure transducer, the injection pressure of detection patient, and pressure transducer uses disposable pressure sensor,
Have that measurement is highly sensitive, data are accurate, null offset is little, Heat stability is good, dielectric withstanding voltage intensity are high,
The features such as measurement scope is wide, the injection pressure data detected are more accurate, and sensitivity is higher.
