Description

Nasal double channel laryngeal mask

technical field

The utility model relates to a laryngeal mask for artificial airway ventilation, in particular to a nasal double-channel laryngeal mask. the

Background technique

At present, the devices for maintaining airway patency and controlling breathing during surgical anesthesia mainly include tracheal tube and laryngeal mask. The mucosal injury is serious, especially the complications related to the laryngeal and tracheal mucosa after a long period of time after operation; However, it is not possible to quickly use the laryngoscope to check and establish a stable airway. It is time-consuming to remove the laryngeal mask and then perform tracheal intubation, and the larger laryngeal mask area also causes greater damage to the patient's mucosa; in addition, most tracheal Neither the catheter nor the laryngeal mask can perform sputum suction on the patient at the same time, or can perform sputum suction on the patient, but they cannot achieve a good sputum suction effect, so that although airway ventilation is achieved, the patient cannot really achieve smooth breathing The endotracheal tube and the laryngeal mask used now all carry out the intubation operation through the oral cavity, which will bring great inconvenience when operations such as the oral cavity and esophagus need to be done, and the patient will feel uncomfortable when using it. the

Utility model content

The utility model provides a transnasal double-channel laryngeal mask with less damage to the tracheal mucous membrane and synchronous airway ventilation and sputum suction operation aimed at the above technical deficiencies. the

A nasal double-channel laryngeal mask, including a ventilation catheter, a cuff, an inflation catheter, an indicator capsule and a one-way valve, the one-way valve is connected to the end of the indicator capsule, and the indicator capsule is connected to the inflation catheter. The inflation catheter is connected with the cuff, and the cuff is V-shaped and wraps around the front end of the ventilation catheter. The utility model also includes a drainage catheter and a suction cup. The suction cup is arranged at the end of the drainage catheter. the

A side port is provided at the position where the cuff is in contact with the ventilation catheter, and the inflation catheter is arranged inside the ventilation catheter and connected to the cuff through the side port. the

The inflation conduit is arranged inside the ventilation conduit close to the inner wall of the ventilation conduit. the

The drainage catheter is arranged inside the ventilation catheter close to the inner wall of the ventilation catheter. the

The cuff of the utility model wraps around the front end of the ventilation catheter in a V-shaped structure, which alleviates the problem that the traditional laryngeal mask is large in size and easily causes damage to the oropharynx and tracheal mucosa, and has good air tightness. the

The design of the drainage catheter described in the utility model can realize the synchronization of the patient's airway ventilation and sputum suction operation, simplify the operation steps, and thus achieve better ventilation effect. the

The suction cup is arranged at the end of the drainage catheter, so that the operation efficiency of suctioning the patient is higher. the

The design that the drainage conduit and the inflation conduit are arranged inside the ventilation conduit, and furthermore, the design that the drainage conduit and the inflation conduit are arranged inside the ventilation conduit close to the inner wall of the ventilation conduit can be controlled only by controlling the outer tube of the ventilation conduit The manufacturing size of diameter meets the requirement of the utility model inserted through the nostril. the

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

Fig. 1 is a schematic structural view of a transnasal double-channel laryngeal mask according to an embodiment of the present invention. the

Detailed ways

As shown in Figure 1, the utility model is a kind of nasal two-way pipeline laryngeal mask, comprising a ventilation catheter 1, a cuff 2, an inflation catheter 3, an indicating vesicle 6 and a one-way valve 7, the one-way valve 7 is connected to the indicating The end of the vesicle 6 indicates that the vesicle 6 is connected to the inflation catheter 3, and the inflation catheter 3 is connected to the cuff 2. The cuff 2 is in a V-shaped structure and wraps around the front end of the ventilation catheter 1. The utility model also includes drainage Conduit 4 and suction cup 5 , the drainage catheter 4 is arranged inside the ventilation catheter 1 close to the inner wall of the ventilation catheter 1 , and the end protrudes from the ventilation catheter 1 , and the suction cup 5 is arranged at the end of the drainage catheter 4 . the

The position where the cuff 2 is in contact with the ventilation catheter 1 is provided with a side port 8 , the inflation catheter 3 is arranged inside the ventilation catheter 1 close to the inner wall of the ventilation catheter 1 , and is connected to the cuff 2 through the side port 8 . the

The suction cup provided at the end of the drainage catheter described in this embodiment has a radius much smaller than that of the ventilation catheter, so that it is not attached to the tracheal mucosa or the mucous membrane of the throat during sputum suction operation. The design of this drainage catheter with a suction cup can be Make suction more efficient for patients. the

The design of the drainage catheter described in this embodiment can realize the synchronous operation of the patient's airway ventilation and sputum suction, simplify the operation steps, and thus achieve a better ventilation effect. the

The design that the drainage catheter and the inflation catheter are arranged close to the inner wall of the ventilation catheter and arranged inside the ventilation catheter can make the utility model meet the requirements of the utility model inserted through the nostrils only by controlling the manufacturing size of the outer diameter of the ventilation catheter , making the design structure of the utility model more reasonable at the same time. the

The above is only the preferred embodiment of the present utility model, it should be pointed out that for those skilled in the art, under the premise of not departing from the structure of the present utility model, some deformations and improvements can also be made, and these will not affect the present utility model. Effects of utility model implementation and practicability of patents. the
