Description

Auxiliary frame in TCD diagnosis senile dementia process

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to auxiliary frame of TCD diagnosis senile dementia in-process.

Background

Transcranial Doppler (TCD) is a non-invasive cerebrovascular disease examination method for detecting the blood flow dynamics and blood flow physiological parameters of intracranial main artery by using the ultrasonic Doppler effect, and by means of pulse Doppler technology and 2MHz transmission frequency, an ultrasonic sound beam can penetrate the thinner part of skull to trace the Doppler signal of intracranial arterial blood flow so as to reflect the functional state of cerebral vessels. Recent studies have shown that TCD has high accuracy and specificity for the diagnosis of senile dementia, and is gradually applied in medicine, while temporal window and occipital window are the main human detection windows for senile dementia.

The temporal window is positioned above the zygomatic arch, and the area from the lateral margin of the orbit to the middle of the front of the ear is generally within the range of the temporal scale of 1-5cm in front of the ear, and can be further divided into 3 areas of the front, middle and back, which become the front, middle and back temples; MCA (middle cerebral artery), ICA (internal carotid artery end), ACA (anterior cerebral artery), and PCA (posterior cerebral artery) were detectable at the temporal window; the occipital window is positioned 2-3cm below the occipital bulge, and in the area which is 2cm beside the left and right midline, when the occipital window is detected, the head and the neck of the occipital window are bent forwards in a prone position so as to expose the large occipital hole and facilitate the transcranial ultrasonic beam detection; VA (vertebral artery), BA (basilar artery), and sometimes PICA (lower posterior cerebellar artery) were detectable at the occipital window.

When the senile dementia is diagnosed, because the occipital window and the temporal window need to be measured at the same time, a patient needs to change the body position in the detection process, which brings unnecessary troubles to the elderly; in TCD detection, because long-time imaging is needed, the detection time is different from 0.5h to 2h, medical staff needs to cling to the skull of a patient by using external force for a long time, and the TCD detection is very inconvenient; meanwhile, the sliding caused by the clothes can also cause unnecessary interference on the final result, and can possibly cause the occurrence of false positive results; chinese patent CN201720419758.8 discloses a fixing frame for ultrasonic probes of a transcranial doppler monitor, which comprises two ultrasonic probes, the fixing frame comprises: the clamping piece comprises two opposite end parts and an elastic body for connecting the two end parts, and the elastic body drives the two end parts to respectively provide clamping force to the inner side; and two cover bodies, its inboard has the binding face that is used for with human head both sides detection window binding, two cover bodies are fixed respectively on two tip of holder, two ultrasonic probe set up respectively on two cover bodies, ultrasonic probe's detection face protrusion binding face, this mount can make ultrasonic probe stabilize binding in monitoring position, eliminate because of the handheld ultrasonic probe shake of medical staff or patient's head removes and lead to ultrasonic probe and detection window to take place the displacement, nevertheless still need the patient to change the position, and only can fix the probe of temporal window department, the flexibility is lower.
