Background

CT examination of the cranium is a method of examining the cranium by CT. The skull CT is a novel examination method which is convenient, rapid, safe, painless and atraumatic to examine, and can clearly display the anatomical relationship of different cross sections of the skull and the specific brain tissue structure. Thereby greatly improving the detection rate of pathological changes and the accuracy of diagnosis. In general, CT images hard tissues better than soft tissues. The skull CT examination has important significance for diagnosing most diseases of the cranium, the skull and the scalp. In recent years, with the wide clinical application of cranial CT examination, especially cranial vascular imaging and cranial perfusion imaging techniques in acute cerebral infarction, qualified and clear image quality is especially important for accurate diagnosis by radiologists. Cranial CTA, CTP examinations typically require the patient to be supine on a CT scanning bed, adducted to the mandible, and require the patient to have both external concha orifices equidistant from the table top. Clinically, the patient who has autonomic consciousness, quiet generally can cooperate with the CT technician to accomplish the head CT inspection, however, the patient of dysphoria delirium, unconsciousness then can't cooperate, often need the family members to assist fixed patient's head in the computer lab, it is consuming time and labouring, the family members also accompany and receive unnecessary radiation, under the condition that the patient is seriously uncoordinated, then need many times of repeated scanning to accomplish the inspection reluctantly, image quality is not exempted from the influence, consequently, be unfavorable for clinically we to this kind of critical patient's diagnosis and treatment, and many times of repeated scanning can make the patient need stand many times of radiation irradiation, lead to the patient's health to suffer unnecessary damage. The lack of an effective skull fixer can enable a fussy critically ill patient to independently cooperate with a CT technician to complete skull CT examination so as to better assist a physician in accurate diagnosis and treatment.

The utility model discloses further set up: the patient pillow is characterized in that a gravity plate is arranged on the bottom surface of the placing groove corresponding to the position of a patient occipital bone, the gravity plate is embedded in the supporting plate, a pressure sensor is arranged in the gravity plate and comprises a pressure sensitive element and a signal processing unit, and the signal processing unit is in communication connection with an external inflating motor to realize the opening of the external inflating motor.

The technical scheme is adopted, and the method has the advantages that: the pressure sensor is adopted, when the head of a patient is placed on the gravity plate, a pressure sensitive element of the pressure sensor receives information and transmits the information to the external inflating motor through the signal processing unit, the external inflating motor receives communication and starts to enable the air bag to start inflating and expanding, the pressure sensor can be a Gibbage JC-1000-HSM type diffusion silicon pressure sensor, the pressure sensor does not introduce much to the functional structure of the pressure sensor in the prior art, and the air bag can better fit the head of the patient to wrap the head of the patient due to the arrangement of the pressure sensor.

The utility model discloses further set up: the outer surface of the first air bag and the outer surface of the second air bag are embedded with temperature sensors, and the temperature sensors are in communication connection with an external inflating motor through communication lines to achieve closing of the external inflating motor.

The technical scheme is adopted, and the method has the advantages that: adopt temperature sensor, when the gasbag contradicts patient's skin, temperature sensor transmits the message of receiving for outside air inflation motor, outside air inflation motor received the message and closed outside air inflation motor's operation this moment, make the gasbag stop expanding, above-mentioned temperature sensor can be for the sie yi ling STT-E platinum resistance temperature sensor, this sensor does not do more for prior art to its functional structure, it sets up on the gasbag, when this sensor contact tip and human surface contact, respond to human surface temperature and transmit the message for outside air inflation motor, make outside air inflation motor close.
