Description
Technical field
The present invention relates to technical field of medical equipment, specially a kind of pressure activated automates contrast apparatus.
Background technology
Conventional Ultrasound cardiogram is widely used in cardiovascular diagnosis at present, but it is when showing micro right-left shunt
Then sensibility is relatively low, is easy to ignore the relevant disease of right-left shunt, such as acleistocardia and pulmonary arteriovenous fistula.And right heartfelt wishes
Learning radiography can be sharp by oscillation physiological saline inject in patient peripheral's venous system, on the basis of conventional Ultrasound cardiogram
With following two principles：1) 10 microns of Contrast agent bubbles >, it is about 15 microns average, pulmonary capillaries net, Bu Nengjin cannot be passed through
Enter a left side and feels concerned about system；2) there are apparent acoustic impedance differences with blood for microvesicle, can clearly be shown individual microvesicle (micro blood flows of low speed)
Show.More detailed right-left shunt information is provided, especially in intracardiac structure (wherein based on acleistocardia) and intrapulmonary
Extremely there is important diagnostic value in the diagnosis shunted.
Patient, which first coordinates, when right heart acoustic contrast carries out Valsalva actions, i.e. patient first blows air blowing detection device
Gas, when it is 40mmHg to measure blow gas pressure, then through peripheral intravenous injection contrast agent, currently used contrast agent is that oscillation is given birth to
Brine microvesicle is managed, two syringes are connected by medical threeway, one of syringe loads physiological saline 9ml, another dress
Air 1ml is carried, medical staff alternately pushes two syringes manually, and physiological saline is vibrated into milky contrast agent microbubble,
This method generates the advantages that bubble velocity is fast, bubble is intensive, economy, safety, non-evident effect.But there is also many for the operation
It is insufficient：1) push of syringe alternating is obstructed larger, is easy to cause medical staff's both hands fatigue, and especially multiple injection or patient's amount is more
When, cause contrast agent microbubble to be formed not up to standard, influences the judgement of diagnosis；2) between different medical workers there is operation technique
Different, especially women medical worker hand-power gas is less than normal, is easy fatigue, and it is unstable to hold syringe, be easy to cause syringe fall off or
Contrast agent microbubble forms not up to standard；3) since the difference of operator's qualification, injection speed have differences, it cannot achieve standard
Change, stability operation；4) at medical treatment peak period, since medical staff is in short supply, and acoustic contrast is cumbersome, seriously affects inspection
Efficiency is surveyed, patient's Waiting time is delayed.
