Double-tube dental pad protective high-frequency jet oxygen sputum suction deflector

Abstract

The invention relates to a double-pipe bite block protection type high-frequency oxygen jet and sputum aspiration fluid director, in particular to double-pipe bite block protection type high-frequency oxygen jet and sputum aspiration fluid director device equipment used for patients with dyspnea. According to the double-pipe bite block protection type high-frequency oxygen jet and sputum aspiration fluid director, an expansion end oropharynx flow guide pipe and a sputum aspiration pipe are sleeved with a bite block sleeve, a flow guide pipe outlet is communicated with the expansion end oropharynx flow guide pipe, and penetrates through the bite block sleeve to be communicated with a flow guide pipe inlet, one end of the sputum aspiration pipe is inserted into the oral cavity, the middle of the sputum aspiration pipe is sleeved with the bite block sleeve and a bite block fender, the other end of the sputum aspiration pipe is communicated with a sputum aspirator, one end of the flow guide pipe inlet is connected with an internal thread conical inserting pipe, an internal thread is connected to an external thread connector, and an external thread conical inserting pipe is communicated with a high-frequency oxygen jet breathing machine. The double-pipe bite block protection type high-frequency oxygen jet and sputum aspiration fluid director has the advantages that the structure is simple, operation is convenient, the double-pipe type bite block sleeve is adopted, oxygen conveying and sputum aspiration for the patients are smooth, cost is lowered, use is safe and stable, and the double-pipe bite block protection type high-frequency oxygen jet and sputum aspiration fluid director is widely used for the high-frequency oxygen jet and sputum aspiration fluid director equipment for the patients with dyspnea.

Description

technical field [0001] The invention relates to a double-tube dental pad protective high-frequency jet oxygen sputum suction deflector, in particular to a double-tube tooth pad protective high-frequency jet oxygen suction deflector device for patients with dyspnea. Background technique [0002] Fiberoptic bronchoscopy (Fibreoptic bronchoscopy, FOB) is a common tool for the examination and treatment of respiratory diseases at present. It is difficult to carry out follow-up treatment that requires multiple operations. In response to this problem, painless FOB examination under intravenous general anesthesia has been widely used clinically in recent years to improve patient compliance. However, because general anesthetics generally have an inhibitory effect on breathing, and most patients with lung disease are elderly, preoperative lung function is often low, and the ventilation path is occupied during the FOB operation, resulting in narrow airway space. Therefore, painless FOB...

Problems solved by technology

However, in the painless FOB examination, it was found that the nasal cannula-mediated HFJV has jet pressure, which can easily cause the nasal cannula to prolapse, and poor ventilation depends on the permeability of the nasal cavity, and the side with better nasal cavity permeability is usually the FOB insertion route At the same time, there is also the possibility of dry turbinates and upper respiratory secretions being blown into the lungs to cause or aggravate lung infection; although HFJV mediated by endoscopic masks, endotracheal tubes, and laryngeal masks can significantly improve the ventilation effect compared with nasal catheters , but it does not effectively solve the problem of the competition between the ventilation tool and the FOB for airway space, nor can it effectively deal with the problem of hypoxia caused by backflow aspiration, and the cost of the three is relatively high, and the operation is not easy enough
