Description
Technical field
This utility model is related to medical instruments field, specifically, is that one kind is applied to battlefield craniocerebral trauma particularly neck
The portable rapid screening device of the tremulous pulse cavernous fistula wounded.
Background technology
Craniocerebral trauma has complexity of seriousness, the universality occurring and diagnoses and treatment of harm etc. in Battlefield trauma injuries
Feature.According to up-to-date domestic data statistics at present, craniocerebral injury incidence rate is 3 ‰, is only second to extremity wound, ranked second position；It is lethal
Rate is 25%, and disability rate 26.1% ranked first position, and basis cranii blood vessel injury can have a strong impact on patient's prognosis, greatly reduces me
Army continues the combat time.Traumatic carotid-cavernous fistulas (traumatic carotid cavernous fistula, TCCF)
Refer to that the carotid artery being caused by wound or its branch flow directly into a kind of arteriovenous communication of cavernous sinus, be the most normal in craniocerebral trauma
One of type seen.The clinical symptoms of TCCF include blepharoedema, and eyeball projects forward, progressive visual deterioration, extraocular muscles fiber crops
Numbness, nervous system dysfunction, eye is beaten with pulse and is beaten.Patient's audible and intracranial blowing murmur, night is more so, right
The Quality of Life of patient is larger.
Because TCCF happening part is hidden, often result in the wounded and fail to obtain corresponding rescue, delay treatment opportunity in time, increase
The wounded are lethal, disability rate, have a strong impact on the fighting capacity level of my army.At present, clinically the goldstandard of diagnosis TCCF is numeral
Subtractive angiography (DSA), is the angiographic method carrying out associated image by electronic computer, and it is appliance computer journey
Sequence is imaged twice to be completed.Before injection contrast agent, carry out first being imaged for the first time, and with computer, image is changed
Digital signal is become to store.After injection contrast agent, re-imaging is simultaneously converted into digital signal.Digital subtraction twice, eliminates phase
Same signal, obtains a blood-vessel image only having contrast agent, it is exactly Digital Subtraction cerebrovascular that this technology is applied to cerebrovascular
Shadowgraph technique.This technology is disadvantageous in that instrument is excessively huge, is unfavorable for that battlefield carries, simultaneously measurement process invasive,
Need to inject contrast agent, process is complicated, be not suitable with that battlefield is in emergency circumstances quick, motor-driven, easily require.Therefore research is new just
Take formula TCCF diagnostic instrumentss to have very important significance for war wound Rapid Screening.
Content of the invention
The purpose of this utility model is to provide a kind of novel portable for the diagnostic equipment of war wound Rapid Screening TCCF.
For achieving the above object, this utility model provides a kind of portable TCCF rapid screening device, including survey meter, and
