Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a head and neck fixing auxiliary device. Background Art
[0002] Ultrasonic examination is a method of examination using the physical properties of ultrasound. It uses the laws of reflection, refraction, absorption and attenuation of ultrasound when it propagates in the human body and encounters different tissues and organs. The disease is diagnosed by using instruments to display the reflection and attenuation of ultrasound by organs and tissues in the body. The body position for ultrasound examination varies according to the different parts of the examination. When conducting an ultrasound examination, the doctor will guide the patient to adopt an appropriate body position and posture according to the specific situation to ensure the accuracy and reliability of the examination. Common body positions include supine, lateral, knee-chest, etc. Some older patients have difficulty changing positions and often require assistance from multiple people, which greatly affects the efficiency of the examination. In particular, critically ill patients or patients with limited mobility need to change positions multiple times to meet the examination needs of different positions during bedside ultrasound examinations of the head and neck. It is difficult for patients to change positions, it takes a long time, and it is difficult to assist, which greatly affects the efficiency and quality of the examination.
[0003] In the existing patent CN220327803U, an adjustable head and neck positioning frame for radiotherapy is disclosed, comprising: a main body, a storage cavity is opened on one side of the top of the main body, and a positioning ring for supporting and positioning the patient's head and neck is arranged inside the storage cavity; an adjustment component, the adjustment component is arranged in the main body, and is used to adjust the positioning ring to change the angle between the positioning ring and the patient's head and neck. In this device, the angle adjustment of the positioning ring is achieved by the engagement of the annular rack to adapt to the patient's body position changes.
[0004] However, in the existing device, the angle of the neck is adjusted by gear rack meshing, which cannot quickly achieve large angle adjustment. The angle adjustment range of one side is small and inflexible, and cannot adapt to the patient's position changes during the examination. In addition, in the existing device, it can only achieve neck adjustment, and the angle of the head cannot change with the angle adjustment of the neck, which is inconvenient to use.
