Description

A cranial ultrasound auxiliary device for bedside dynamic monitoring technology

technical field

The application relates to a cranial ultrasound auxiliary device for bedside dynamic monitoring technology, which belongs to the technical field of medical auxiliary equipment.

Background technique

At present, cranial ultrasonography in clinical application mainly includes: transcranial Doppler (TCD), transcranial color-code real time sonography (TCCS), transcranial contrast-enhanced ultrasound , t-CEUS).

Among them, TCD has the longest development history and the most widely used cranial ultrasonography technique. Because adult patients are covered by the skull, it is difficult for sound waves to penetrate the skull for imaging. Therefore, when performing TCD examination, the operator needs to hold the probe and repeatedly probe at the weak part of the patient's pterional skull in order to obtain intracranial blood flow signals. Due to the small detection window, it is often easy to shift and lose blood flow signals. Therefore, the TCD auxiliary bracket was born to help the operator perform the inspection (as shown in Figure 1). Currently, the auxiliary bracket includes a head fixing component and a probe fixing component. The internal fixation component is that two cross straps are set on the skull, and the probe A is fixed on the probe fixation component.

TCCS technology combines the color Doppler mode on the basis of TCD two-dimensional gray-scale images to obtain more clear information on the distribution and course of intracranial blood vessels, which is convenient for the examiner to adjust the angle between the sound beam and blood vessels to obtain more accurate Doppler Le blood flow spectrum. At the same time, it can also observe intracranial structural abnormalities, dynamically evaluate cerebral blood flow regulation function, and evaluate brain tissue perfusion through contrast mode (ie t-CEUS technology). During the inspection, the operator holds a high-frequency ultrasound probe and also selects the weak point of the skull or the defect of the skull at the temporal point for exploration. Like the traditional TCD examination, the TCCS examination window through the temporal window is small, and the hand-held probe is easy to shift and lose the image, so the stability of the relative position of the probe and the skull is highly required. However, there is still a lack of auxiliary devices for this examination clinically, and the existing TCD auxiliary brackets cannot be used universally, and are not suitable for wearing and fixing for critically ill patients in the supine position.

In summary, the disadvantages of the existing TCD auxiliary brackets are: 1) it is only suitable for specific TCD inspection probes, and it is not universal with TCCS probes; Pressure sores; 3) Some neurologically ill patients have different degrees of skull defects after decompressive craniectomy, so they cannot wear the auxiliary device.
