Abstract

The utility model belongs to a laryngeal mask used for manual airway ventilation, in particular to an intranasal laryngeal mask with two-way conduits, which comprises a ventilation conduit, a cuff, an inflating conduit, an indicating vesicle, a non-return valve, a drainage conduit and a sucking disk, wherein the non-return valve is connected with the tail end of the indicating vesicle; the indicating vesicle is connected with the inflating conduit; the cuff adopts a V-shaped structure and wraps around the front end of the ventilation conduit; the inflating conduit is connected with the cuff; the drainage conduit is arranged inside the ventilation conduit, and the tail end of the drainage conduit extends out of the ventilation conduit; and the sucking disk is arranged at the tail end of the drainage conduit. The intranasal laryngeal mask causes less damage to tracheal mucosa of a patient, can achieve airway ventilation and sputum suction operation synchronously, can better achieve the sputum suction operation, brings greater convenience to the patient and medical staff through the intranasal design, and alleviates the discomfort of the patient.

Description

The bilateral pipeline laryngeal mask of per nasal
Technical field
This utility model relates to a kind of laryngeal mask of the artificial airway's of being used for ventilation, relates in particular to a kind of bilateral pipeline laryngeal mask of per nasal.
Background technology
At present; The device of when surgery anesthesia, keeping airway patency and control breathing mainly contains endotracheal tube and laryngeal mask; The endotracheal tube caliber is thicker; And the lower end is designed to pointed bore, insert and keep in the venting process heavier to throat and tunica mucosa tracheae damage, especially the long period postoperative throat and the related complication rate of tunica mucosa tracheae higher; The laryngeal mask caliber is also relatively thicker; And laryngeal mask air bag volume is bigger; Take position, whole oral cavity, can not utilize laryngopharyngeal mirror to check and stablize the foundation of air flue in some cases fast, pull out laryngeal mask and carry out tracheal intubation again; More time-consuming, and bigger laryngeal mask area is same bigger to patient's mucosa injury; In addition, most endotracheal tube and laryngeal mask all can not be inhaled the expectorant operation to the patient simultaneously; Perhaps can inhale the expectorant operation to the patient; But do not reach good suction expectorant effect, thereby, can not really make the patient realize breathing smooth and easy though realized airway pressure; The endotracheal tube that uses now all is that trans-oral is carried out the intubate operation with laryngeal mask, can bring very big inconvenience when doing operation such as oral cavity, esophagus when needs, and the while can not feel well when the patient uses.
The utility model content
This utility model is that provide to above-mentioned technical deficiency a kind of damages little, as can to realize the per nasal that airway pressure is synchronous with inhaling expectorant operation bilateral pipeline laryngeal mask to tunica mucosa tracheae.
A kind of bilateral pipeline laryngeal mask of per nasal comprises airway, cover capsule, inflating catheter, indication vesicle and check valve, and check valve is connected the end of indication vesicle; The indication vesicle is connected with inflating catheter, said inflating catheter with overlap capsule and link to each other, overlap the V-shaped structure of capsule and surround the front end of airway; This utility model also comprises drainage catheter and sucker; Said drainage catheter is arranged on airway inside, and end stretches out airway, and said sucker is arranged on the end of drainage catheter.
The position that said cover capsule contacts with airway is provided with a side mouth, and said inflating catheter is arranged on airway inside, and links to each other with said cover capsule through the side mouth.
Said inflating catheter is close to the airway inwall and is arranged on airway inside.
Said drainage catheter is close to the airway inwall and is arranged on airway inside.
It is bigger that the design that the V-shaped structure of the said cover capsule of this utility model surrounds the front end of airway has alleviated traditional laryngeal mask volume, oropharynx, tunica mucosa tracheae is prone to cause the problem of damage, and has good air-tightness.
The design of the said drainage catheter of this utility model can realize the patient airway ventilation and inhale carrying out synchronously of expectorant operation, the step that simplifies the operation, thus reach better ventilatory effect.
Said drainage catheter end is provided with the design of sucker, can make patient's suction expectorant operating efficiency higher.
Said drainage catheter and inflating catheter are arranged on the inner design of airway; And further say; Said drainage catheter and inflating catheter are close to the airway inwall and are arranged on the inner design of airway; Can only pass through the manufacturing dimension of the outer tube diameter of the said airway of control, satisfy the requirement that this utility model inserts through the nostril.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further detailed explanation:
Fig. 1 is the structural representation of the bilateral pipeline laryngeal mask of this utility model embodiment per nasal.
The specific embodiment
As shown in Figure 1, the bilateral pipeline laryngeal mask of a kind of per nasal of this utility model comprises airway 1, cover capsule 2, inflating catheter 3, indication vesicle 6 and check valve 7; Check valve 7 is connected the end of indication vesicle 6; Indication vesicle 6 is connected with inflating catheter 3, said inflating catheter 3 with overlap capsule and link to each other 2, overlap capsule 2 V-shaped structures and surround the front end of airway 1; This utility model also comprises drainage catheter 4 and sucker 5; Said drainage catheter 4 is close to airway 1 inwall and is arranged on airway 1 inside, and end stretches out airway 1, and said sucker 5 is arranged on the end of drainage catheter 4.
The position that said cover capsule 2 contacts with airway 1 is provided with a side mouth 8, and said inflating catheter 3 is close to airway 1 inwall and is arranged on airway 1 inside, and links to each other with said cover capsule 2 through side mouth 8.
The terminal sucker that is provided with of the said drainage catheter of present embodiment; Its sucker radius is much smaller than the airway radius; Guarantee that it is not attached on tunica mucosa tracheae or the bottleneck throat mucosa when inhaling the expectorant operation, the design that this kind has the drainage catheter of sucker can make patient's suction expectorant efficient higher.
The design of the said drainage catheter of present embodiment can realize the patient airway ventilation and inhale carrying out synchronously of expectorant operation, the step that simplifies the operation, thus reach better ventilatory effect.
Said drainage catheter and inflating catheter are close to the airway inwall and are arranged on the inner design of airway; Can make this utility model only pass through the manufacturing dimension of the outer tube diameter of the said airway of control; Satisfy the requirement that this utility model inserts through the nostril, make that simultaneously this utility model project organization is more reasonable.
Above-described only is the preferred implementation of this utility model; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from this utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that this utility model is implemented.
