Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a head fixing device for children's bronchoscopic examination. Background Art

[0002] Bronchoscopes are soft, flexible, and have good illumination. They are also easy to operate and safe. Bronchoscopy and interventional treatment have become important means of diagnosis and treatment of respiratory diseases and have been widely used in clinical practice. As an invasive procedure, sedatives such as midazolam are often used before bronchoscopy. However, bronchoscope stimulation during the examination may still cause the child to become restless, which will affect the smooth progress of bronchoscopy and even lead to unplanned withdrawal of the scope or adverse reactions such as airway bleeding and mucosal injury. Therefore, good posture restraint can help the examination go smoothly and reduce accidental injuries to the child.

[0003] The flexible bronchoscope enters the airway through the child's nasal cavity for examination, irrigation and medication. After the mirror enters the airway, the child will produce involuntary resistance due to strong stimulation. Among them, the patient's head movement can directly affect the entry and operation safety of the bronchoscope. At present, it is common in clinical practice to use restraint belts to brake the patient's trunk, elbows, wrists, knees and other joints, which can control the child's limb movement to a certain extent, but there is a lack of head fixation devices. During the examination, an auxiliary operator is still required to fix the patient's head with both hands to play a certain restraining role. However, due to factors such as difficulty in controlling the force and fatigue caused by the long duration of the examination, human fixation cannot effectively control the violent shaking of the child's head when he is agitated, affecting the smooth progress of the examination, increasing the incidence of complications such as bleeding and injury, and may lead to prolonged examination operation time, increased operation risks and failure rates, and increased labor costs, resulting in a decrease in the success rate of a single examination or interference with the effect of interventional treatment, and also increasing the economic burden on patients.
