Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of dizzy checkout equipment, relate in particular to the dizzy detector of a kind of eyeshield formula, be mainly used in the detection analysis of the dizzy symptom of nystagmus.
Background technology
Dizzyly be considered to for a long time a kind of very difficult definition, cannot measure, diagnose the syndrome that is full of challenge, treatment and is full of problem.Subjective sensation when its outbreak can be summarized as Four types.(1) dizzy: a kind of rotation sense of self and external environment; (2) faint: the sensation before a kind of fainting or while being about to faint; (3) unbalance: a kind of sensation that cannot keep balance; (4) dizzy or non-specific dizziness: a kind of more ambiguous, dizzy or dizzy sensation of being difficult to describe.This Four types affects clinical practice so far, but constantly suffers in recent years the query of clinical practice and research.17 hospitals by under 5 famous medical college of the U.S.'s state-run commune hospital fund support have participated in research, by following the tracks of 300 many cases patients with vertigo, find that patient over half can not affirm its symptom or describe accurately.This research is also respectively from the angle of more than 400 emergency treatment doctors and 300 many cases Emergency Patients, further studied the effect of 4 kinds of classical subjective sensation types in diagnosis.Found that, the error of overemphasizing or rely on the type of subjective sensation to diagnose is larger, the probability of mistaken diagnosis is higher, too relies on the character of subjective sensation to differentiate that source of disease uncertainty is larger, in conjunction with other features of paresthesia epilepsy and bedside inspection carrys out difference maincenter and periphery may be more accurate.HINTS bedside method of diagnosis is exactly wherein a kind of.HINTS is being collectively referred to as of a pulse testing, nystagmus, eye three bedside inspections of deflection.The sensitivity of HINTS bedside inspection technique and accuracy, all higher than early mri, especially contribute to the false vestibular neuronitis of differentiating that in acute vertiginous syndrome vestibular neuronitis and apoplexy cause.
No. 200510041843.7 patents of Chinese patent disclose a kind of Electronystagmogram, ear ending blood flow signal synchronous analyzer for detecting, be used for dizzy disease to diagnose, its general information is as follows: cause nystagmus and the dizzy autonomic nervous dysfunction of causing according to dizzy, thereby the peripheral vessel spasm that causes face causes face's tip blood supply insufficiency, the clinical symptoms of ear ending blood supply insufficiency, launch directive eyeball surface by low-light, form hot spot-form the hot spot of beating when nystagmus hot spot at eyeball surface, the hot spot of beating adopts video camera (CCD) to obtain nystagmic image, and by grating device by nystagmic kinematic axis to differentiating nystagmus horizontal vibration amplitude or vertical amplitude, or unordered trembling, grating device is horizontal grate, in the time of nystagmus horizontal vibration amplitude, hot spot is beated and is broadcast figure for horizontal continuity, in the time of nystagmus vertical amplitude because grating device is horizontal grate, the hot spot seriality of beating is cut into breakpoint ripple figure by horizontal grate, gather by ccd signal, computer processing calculates frequency, amplitude, identification nystagmus is vertical amplitude or horizontal vibration amplitude.The problem that this detecting instrument exists has: (1) detect dizzy according to one of be only vertical amplitude or horizontal vibration amplitude nystagmus, not intuitively Electronystagmogram or accurately nystagmus data as diagnosis basis; (2) when the position of grating is incorrect, can be to nystagmic kinematic axis to causing a deviation; (3) in the time that low-light transmitting is inhomogeneous or angle is incorrect, also may be to nystagmic kinematic axis to causing a deviation.(4) because the formation of hot spot is the hot spot that eyeball surface forms, not the light directly being sent by pupil, cause diagnostic result may occur error.(5) relate to computer and host computer, integrated level is low, and cost is relatively high; In addition, it is bulky, detects and makes troubles to Diagnosis of Vertigo.
