Double-tube bite block protection type high-frequency oxygen jet sputum suction fluid director

Abstract

The invention discloses a double-tube bite block protection type high-frequency oxygen jet sputum suction fluid director, which comprises an oropharyngeal fluid director, a sputum suction tube, an occlusion pad sleeve and a sleeve, wherein a sputum suction tube outer connector penetrating through the sputum suction tube is transversely arranged on the sleeve in a penetrating mode; a fluid directorbayonet for clamping the oropharyngeal fluid director is arranged at the front end of the sleeve; and the fluid director bayonet transversely penetrates through the sleeve; a check ring for limitingis arranged on the outer wall of the sleeve; and the occlusion pad sleeve is assembled outside the sleeve. The double-tube bite block protection type high-frequency oxygen jet sputum suction fluid director has a simple structure and is convenient to operate, is capable of conveying oxygen to a patient and smoothening sputum suction and exhausting through a double-tube seaming cushion cover type silica gel oropharyngeal airway, helps reduce pains of the patient, lowers the cost, is safe and stable to use, and is widely applicable to various devices of high-frequency oxygen jet, sputum suction and flow guide breathing for dyspnea patients.

Description

technical field [0001] The invention relates to a double-tube dental pad protective high-frequency jet oxygen sputum suction deflector. Background technique [0002] With the aggravation of air pollution, the incidence of lung diseases is increasing year by year. Lung cancer ranks first among malignant tumors, reaching 787,000 people nationwide. More and more patients need Painless VedioBronchoscopes (PLVB) diagnosis and treatment. Good ventilation measures are of great significance to the smooth implementation of PLVB. Various ventilation measures commonly used at present have certain defects. For example, the existing ventilation-mediated tools compete with electronic bronchoscopes (VedioBronchoscopes, PLVB) for airway space, and anesthesiologists are often required to stand on the head for face masks during operations. Pressurized assisted ventilation will cause a lot of inconvenience in LVB operation and rescue. Therefore, how to avoid airway competition, facilitate ve...

Problems solved by technology

However, in the PLVB examination, it was found that nasal cannula-mediated HFJV has jet pressure, which can easily lead to nasal cannula prolapse, poor ventilation, and dependence on the permeability of the nasal cavity, and the side with better nasal cavity permeability is usually the LVB insertion route. There are disadvantages, and there is also the possibility of dry turbinates and upper respiratory secretions being blown into the lungs to cause or aggravate lung infections; although HFJV mediated by endoscopic masks, endotracheal tubes, and laryngeal masks can significantly improve the ventilation effect compared with nasal catheters, However, it does not effectively solve the problem of the competition between the ventilation tool and the LVB for airway space, nor can it effectively strengthen the suction in a timely manner to 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.
