Rigid bronchoscopes are used for diagnosis and treatment of a variety of indications of the bronchial system. In particular, in interventional diagnosis and treatment means such as foreign body extraction, tumor ablation or stent implantation, the hard bronchoscope has been praised as the golden standard. A key factor in these medical approaches is ensuring that the working channel of the bronchoscope is as spacious as possible. This may facilitate simultaneous or separate access of various medical forceps and instruments to the desired treatment site. Advantages of rigid bronchoscopy techniques over flexible bronchoscopy techniques include the ability to maintain airway passage, the treatment of large hemoptysis, shorter interventional treatment times, and the acquisition of large biopsy specimens. Some procedures must be performed with rigid bronchoscopes, such as the seizing of highly difficult foreign bodies, the insertion of silicone stents, and the removal of various stents. In use, from an anaesthetic perspective we find the following problems: 1. the hard bronchoscope is easy to damage teeth when inserted; 2. the rigid bronchoscope cannot seal the air passage, and the conventional mechanical ventilation cannot be used.

The utility model discloses a following technical scheme realizes above-mentioned purpose:
a ventilation auxiliary device for hard bronchoscope examination comprises an air duct, wherein one end of the air duct is connected with a breathing machine through an air inlet connector, and the other end of the air duct is provided with an air outlet; the mid-mounting of air duct has the anti-reflux cover that is used for preventing gaseous backward flow, prevent the reflux cover with movable nested has the mouth of a bite between the connector admits air.
Preferably, the backflow prevention sleeve is a soft rubber sleeve.
Preferably, the backflow prevention sleeve comprises an integrally formed gas blocking ring and a sleeve body, and the sleeve body is sleeved with the gas guide tube and tightly attached to the outer wall of the gas guide tube.
Preferably, the gas baffle ring is elliptical.
Preferably, the mouthpiece is made of silica gel.
Preferably, the mouthpiece comprises a mouth blocking part, a bite part and a tooth blocking part which are integrally formed, and the bite part is movably connected with the air guide tube in a nested manner.
Preferably, the mouth blocking part is an arc-shaped patch which can be attached to the lips.
To sum up, the utility model has the advantages that: the anti-reflux sleeve is tightly attached to the middle part of the air duct, so that reflux leakage in the air duct of a patient can be prevented, air leakage is reduced, the patient can obtain satisfactory tidal volume, minute ventilation volume, air duct pressure and normal exhaled carbon dioxide in the checking process, air pressure injury caused by air duct drying and jet ventilation caused by high flow is avoided, and oxygen reserve of the patient is increased. And the teeth of the patient can be protected by adopting the mouthpiece.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a ventilation auxiliary device for hard bronchoscope examination, which comprises an air duct 1, wherein one end of the air duct 1 is connected with a breathing machine through an air inlet connector 1a, and the other end is provided with an air outlet 1 b; the breathing machine can provide oxygen for the patient, and the patient is ensured to be examined and treated under the breathing of a normal physiological state to the maximum extent. The mid-mounting of air duct 1 has the backflow prevention cover 3 that is used for preventing gaseous backward flow, backflow prevention cover 3 with movable nested has mouthpiece 2 between the connector 1a that admits air. The backflow prevention sleeve 3 can reduce air leakage, maximally seals an air passage on the premise of not influencing the operation of a doctor, and is matched with a breathing machine to inhale oxygen, so that the safety of a patient is ensured. When the patient with the hard bronchoscope uses the device, the patient bites the mouthpiece 2, and the teeth can be prevented from being damaged.
