A cervical collar having an anterior component including a main support, an intermediate support pivotally connecting to the main support at a rear portion of the anterior component, and forming a frontal opening with the main support. An adjustment mechanism connects the main support to the intermediate support and locks a position of the intermediate support relative to the main support at a front portion of anterior component. The adjustment mechanism has an actuator for disengaging the main support from the intermediate support at the front portion and permits the intermediate support to pivot relative to the main support at the rear portion to vary a height of the frontal opening. A posterior component of the cervical collar is adapted to provide improved anterior-posterior and lateral occipital support.

This utility model discloses a head-mounted support and surgical field imaging device. The head-mounted support includes: a front support for wearing on the forehead; a rear support for wearing on the occipital bone; the front and rear supports are connected by a connecting strap; and at least two mounting bases, each switchably mounted on the front side wall of the front support, and each mounting base is used to accommodate different functional devices. Multiple mounting bases can be selectively mounted on the front support, and different mounting bases can accommodate different functional devices. Thus, by changing the mounting base, the functional device mounted on the head-mounted support can be changed. Users can select the required functional device according to their actual needs, install it on the corresponding mounting base, and then install that mounting base on the front support, making the head-mounted support compatible with different functional devices, thereby improving the ease of use of the head-mounted support.

The invention relates to an intracranial pressure noninvasive detection model construction method based on FVEP multi-feature positioning, and belongs to the technical field of medical equipment. According to the method, a visual evoked potential signal transmitted by a visual pathway is obtained at the occipital bone of a human body on the basis of flash stimulation with certain frequency, certain light intensity and certain stimulation times of a specific light source by utilizing the relevance between an FVEP signal and intracranial pressure, and signal processing and multi-feature extraction are performed on the visual evoked potential signal under multiple times of flash stimulation; and a flash visual evoked potential multi-feature data set is constructed, so that a non-invasive intracranial pressure detection model is constructed, and non-invasive detection reflecting the brain pressure state of a human body is realized. According to the method, the robustness of the FVEP signal multi-feature positioning algorithm is effectively improved, so that the noninvasive intracranial pressure detection model has higher detection precision and stability, the change of the craniocerebral pressure state is revealed more reliably, and a higher-precision intracranial pressure noninvasive detection means is provided for clinic.
