Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of dizzy checkout equipment, particularly relate to the dizzy detector of a kind of eyeshield formula, be mainly used in the detection analysis of nystagmus vertigo symptoms.
Background technology
Dizzyly be considered to a kind of very difficult definition for a long time, cannot measure, diagnose be full of challenge, syndrome that treatment is full of problem.Subjective sensation during its outbreak can be summarized as Four types.(1) dizzy: a kind of rotation sense of self and external environment; (2) faint: a kind of faint before or the sensation that is about to when fainting; (3) unbalance: a kind of sensation that cannot keep balancing; (4) dizzy or non-specific dizziness: a kind of more ambiguous, sensation of being difficult to giddy or the dizziness described.This Four types affects clinical practice so far, but constantly suffers the query of clinical practice and research in recent years.17 hospitals belonging to 5 famous medical college of U.S. National Institutes fund support take part in research, by following the tracks of 300 many cases patients with vertigo, find that patient over half can not affirm or describe accurately its symptom.This research also respectively from the angle of more than 400 emergency physicians and 300 many cases Emergency Patients, further study the effect of 4 kinds of classical subjective sensation types in diagnosis.Found that, the error overemphasized or rely on the type of subjective sensation to carry out diagnosing is larger, the probability of mistaken diagnosis is higher, undue rely on the character of subjective sensation to differentiate source of disease uncertainty is comparatively large, in conjunction with paresthesia epilepsy other features and maincenter is distinguished in bedside inspection and periphery may be more accurate.HINTS bedside method of diagnosis is exactly wherein a kind of.HINTS is a pulse testing, nystagmus, being collectively referred to as of eye deflection three bedside inspections.The sensitivity of HINTS bedside inspection technique and accuracy, all higher than early mri, especially contribute to the false vestibular neuronitis differentiating that in acute vertiginous syndrome vestibular neuronitis and apoplexy cause.
No. 200510041843.7, Chinese patent patent discloses a kind of Electronystagmogram, ear ending blood flow signal synchronous analyzer for detecting, be used for diagnosing dizzy disease, its general information is as follows: cause nystagmus according to dizzy and dizzyly cause autonomic nervous dysfunction, thus cause the peripheral vessel spasm of face to cause face's tip blood supply insufficiency, the clinical symptoms of ear ending blood supply insufficiency, directive eyeball surface is launched by low-light, hot spot-namely form the hot spot of beating when nystagmus hot spot is formed 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 resolution nystagmus horizontal vibration amplitude or vertical amplitude, or unordered trembling, grating device is horizontal grate, when nystagmus horizontal vibration amplitude, hot spot is beated for horizontal continuity broadcasts figure, when nystagmus vertical amplitude because grating device is horizontal grate, hot spot seriality of beating is cut into breakpoint ripple figure by horizontal grate, gathered by ccd signal, computer disposal calculates frequency, amplitude, identify that nystagmus is vertical amplitude or horizontal vibration amplitude.This detecting instrument Problems existing 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) position when grating is incorrect, can to nystagmic kinematic axis to causing a deviation; (3) when low-light transmitting is uneven or angle is incorrect, also may to nystagmic kinematic axis to causing a deviation.(4) because the formation of hot spot is the hot spot that eyeball surface is formed, not the light directly sent by pupil, cause diagnostic result to occur error.(5) relate to computer and host computer, integrated level is low, and cost is relatively high; In addition, it is bulky, and detecting to Diagnosis of Vertigo makes troubles.
