Description
Technical field
The utility model is related to the field of medical instrument technology more particularly to a kind of CT contrast medium extravasation real time monitoring apparatus.
Background technology
CT enhancing scannings are by intravenous injection iodine contrast medium of the high pressure injector from patient, due to many reasons injection site
It is likely to occur iodine contrast medium to escape in surrounding soft tissue from blood vessel, as contrast medium exosmoses, and can cause local organization osmotic pressure
Increase, generate subcutaneous tissue swelling, pain, feeling of numbness, or even festers, the changes such as necrosis.The extravasation of monitoring contrast medium is main at present
It is to use eyes close-ups injection at one's side in patient by medical staff during high pressure injector injects iodine contrast medium
With the presence or absence of extravasation.This mode has the following defects.
First, since CT scan has radiation injury, while Enhanced CT has certain phase requirement, and medical staff one
As when being the bolus iodine contrast medium since high pressure injector, in scanning room close-ups patient injection site for a period of time,
Confirm it is without exception after leave scanning room, start CT scan.At this time high pressure injector continue bolus iodine contrast medium, and medical staff without
The extravasation situation of method close-ups injection site.So relying on the personal monitoring of medical staff's naked eyes close-ups at present
Method whole closely can not monitor whether iodine contrast medium exosmoses.Especially CT blood vessel imagings and CT Perfusion Imagings, often require that
High pressure injector bolus iodine contrast medium and CT scan are carried out at the same time, therefore, medical staff can only by preform injection physiological saline come
The ability to bear and extravasation risk of patient vessel are judged indirectly, and cannot the closely directly observation injection in bolus iodine contrast medium
Whether position there is contrast medium extravasation；
Second, for most patients, bolus iodine contrast medium Early observation is given birth to for a period of time or by preform injection
Reason brine judges that extravasation risk is all reliable indirectly.But few patients are due to poor (such as vein blood vessel of native blood vessel situation
Hardening, brittleness increase or blood vessel is too thin) or patient compliance's degree poor (such as infant, the elderly, prolonged illness body decline, obnubilation
Patient etc.), it sometimes appear that bolus iodine contrast medium early stage does not exosmose, but the later stage exosmoses；Or preform injection
The case where not exosmosing when physiological saline, but exosmosing when the bolus iodine contrast medium of back；
Third, although medical staff can link up with patient in advance, allow patient in feels pain by gesture to doctor
Shield personnel prompt contrast medium extravasation, but since patient experience is insufficient or the influence of intense strain, sometimes will appear and misdeem
Accidentally.Do not occur exosmosing and but terminate administration, influences entirely to check；Occur exosmosing but without terminating administration in time, add
Contrast medium extravasation is weighed.
Utility model content
The utility model is intended to provide CT contrast medium extravasation real time monitoring apparatus, and patient is worn in real time when CT enhances inspection
With, it can monitor whether patient's contrast medium injection position the case where contrast medium extravasation occurs.
