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 HFJ

Embodiment 1

[0027] refer to figure 1 , figure 2 with image 3 A double-tube tooth pad protective high-frequency jet oxygen suction deflector is shown, including an oropharyngeal drainage tube 1, a sputum suction tube 2, an occlusal pad cover 3 and a sleeve 4; the sleeve 4 runs through A sputum suction tube external interface 401 for passing through the sputum suction tube 2 is provided, and the front end of the sleeve 4 is provided with a guide tube bayonet 402 for clamping the oropharyngeal guide tube 1 , the The guide tube bayonet 402 runs through the casing 4 transversely; a retaining ring 403 for limiting is provided on the outer wall of the casing 4, and the snap-in gasket 3 is assembled on the outside of the casing 4, and snaps together The pad cover 3 is limited to the left side of the retaining ring 403, and the inner side of the occlusal pad cover 3 is injection-molded with an inner opening 302 for clamping the oropharyngeal drainage tube 1. A sub-connector 5 is provided at t...

Embodiment 2

[0031] refer to Figure 4 with Figure 5 As shown, the difference from Example 1 is that a fixing hole 411 for fixing the occlusal cushion 3 is processed on the surface of the retaining ring 4, and a spherical hole is formed on the right end of the occlusal cushion 3 by injection molding. The positioning block 311 passes through the fixing hole 411 to the right after the positioning block 311 is deformed, and at this time, the occlusal pad cover 3 and the retaining ring 4 are fixed.

Embodiment 3

[0033] refer to Image 6 , Figure 7 , Figure 8 with Figure 9 As shown, it is an embodiment of the present invention, the sub-connector 5 includes a socket pipe 501, and the left side of the socket pipe 501 has a plurality of tapered sealing surfaces 511, and a sealing surface is formed between two adjacent sealing surfaces 511. The fault surface 512 is formed by injection molding on the outer wall of the insertion tube 501 to form a first retaining ring 502, and the first retaining ring 502 is located at the right side of the sealing surface 511; the right end of the insertion tube 501 is formed by injection molding There is a joint 503, the inner side of the joint 503 is injection-molded with an inner tube 504, and a communicating inner hole 513 is formed between the inner tube 504 and the insertion tube 501; between the joint 503 and the insertion tube 501 A plurality of reinforcing plates 514 are formed by injection molding; the female connector 6 includes a first ins...

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...
