Description

Disposable special mask for nasal bronchoscopy

technical field

The utility model belongs to the technical field of medical equipment, and in particular relates to a disposable special mask for transnasal bronchoscopy.

Background technique

Bronchoscopy has been widely used in clinical practice as a means of diagnosis and treatment of respiratory diseases. As an invasive minimally invasive diagnosis and treatment technology, transnasal bronchoscopy requires a certain degree of cooperation from patients. When specialists perform transnasal bronchoscopy for patients, the bronchoscope is routinely inserted into the patient's trachea through the nostrils. Even if anesthetics are used, the operation often stimulates the patient to cough to varying degrees. Clinically, when medical staff perform this examination for patients with pulmonary infectious diseases or unexplained pulmonary infections, especially when examining patients with infectious diseases (such as tuberculosis, etc.) Locally formed aerosols contain a large number of pathogenic microorganisms, which can easily infect medical staff. Even when medical staff wear surgical masks, there is a significant risk of exposure. At present, no very effective protective measures have been taken for such situations in clinical practice.

In order to reduce the risk of exposure, the current general practice of medical staff is to wear a disposable medical surgical mask for patients with suspected infectious diseases, and then dig a moderately sized hole in the mask corresponding to the nostril, so that the bronchoscope can smoothly enter the patient through this hole. nasal cavity. On the one hand, this approach is because the size of the hole is not easy to control, and it is inconvenient to enter and exit the bronchoscope. At the same time, when providing oxygen for the patient, the nasal oxygen tube needs to be placed under the mask, which destroys the integrity of the mask and the sealing of the edges. Affect the protective effect of masks. On the other hand, the mask will cover the patient's face and lips. When the patient develops hypoxia and cyanosis, the medical staff cannot observe the color change of the patient's face and lips in time, and there are obvious safety hazards in the operation.
