Description

Technical Field

[0001] The invention relates to the technical field related to medical devices, and in particular to a device for fixing the head of a child during bronchoscopic alveolar lavage. Background Art

[0002] Bronchoalveolar lavage is a new technology developed on the basis of fiberoptic bronchoscopy. It is a method of using a bronchoscope to inject normal saline into the bronchoalveoli and then aspirate it, collect the effective liquid on the alveolar surface, and examine its cellular components and soluble substances. It is clinically used to diagnose a variety of lung diseases, such as alveolitis, pulmonary fibrosis, asbestosis, lung cancer, pneumocystis carinii, pulmonary alveolar proteinosis, etc. Clinical diagnosis, differential diagnosis, and study the etiology, pathogenesis, evaluation of efficacy and prognosis of lung diseases. At present, the following problems may occur when performing bronchoalveolar lavage:

[0003] 1. Most of the current modern beds have the function of adjusting the body position angle. However, during bronchoalveolar lavage, the patient needs to keep the head tilted back to insert the bronchoscope into the body for alveolar lavage. However, if the patient keeps the head tilted back for a long time, he will easily get tired and uncomfortable. Over time, the patient's head is also prone to move, which can easily cause harm to the patient, especially for children. The head is easy to move, and someone needs to fix the child's head, which will cause serious physical exhaustion over a long period of time.

[0004] 2. At present, during bronchoalveolar lavage, it is difficult to adjust the height of the patient's head according to the patient's body shape and actual situation. The support height cannot be adjusted quickly according to different patients, and there is a lack of support for the patient's back, resulting in reduced patient comfort;

[0005] 3. Currently, when performing bronchoalveolar lavage, in order to ensure the lavage effect and prevent the bronchoscope from contacting the patient's face and bed, the bronchoscope needs to be lifted, which can easily cause fatigue over time. Summary of the invention
