Abstract
The utility model relates to a laryngeal mask ventilating device. The laryngeal mask ventilating device comprises a conduit joint, an air flue conduit, a connecting joint, an air bag, an air inflation pipe, an indicating air bag and a one way valve. The conduit joint is arranged at one end of the air flue conduit, the other end of the air flue conduit is connected with the air bag by the connecting joint, the air inflation pipe is connected with the air bag, and the indicating air bag and the one way valve are arranged on the air inflation pipe. The laryngeal mask ventilating device is characterized in that the air flue conduit and the connecting joint are formed in an integral manner, the air flue conduit is arc-shaped, and the curvature radius is selected within 140 to 160mm. the laryngeal mask ventilating device can ensure the smoothness by the integral forming, and the structure is reliable. Compared with the prior art, the laryngeal mask ventilating device has the following beneficial effects: when a laryngeal mask is inserted into and pulled out, slight injury can be incurred at inner wall mucosa of an air flue; practices prove that cardiovascular systems have weak response in operation, and the sore throat probability of patients after operation is fairly low; moreover, the curvature radius of the air flue conduit is improved, so as to lead the operation to be easily carried out, and reduce pains of the patients as well.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to the laryngeal mask airway device of using when surgery anesthesia or critical patient rescue.
Background technology
When surgery anesthesia and critical patient rescued, setting up effective artificial airway in the very first time had crucial meaning to improving salvage success rate.For keeping respiratory ventilation, Chang Yong artificial airway device comprises breathing mask, tracheal intubation, laryngeal mask etc. now.Though breathing mask is simple and easy to do, generally can not provide positive pressure ventilation, and the efficient of ventilation depends on patient's autonomous respiration to be also noted that whether respiratory airway is unimpeded, more be the mode of tracheal intubation and laryngeal mask so nowadays use.
Laryngeal mask is compared with tracheal intubation, has the following advantages again: 1. the patient kept autonomous respiration when laryngeal mask was inserted, and did not need laryngoscope when the patient operates, and can carry out under the blind spy; 2. laryngeal mask is not inserted trachea, stimulate little, easily tolerance; 3. laryngeal mask inserts and extracts hemodynamic effects little; 4. little to the influence of intraocular pressure and intracranial pressure; Laryngeal mask time of inserting short, be easy to grasp.
Yet still there is certain defective in existing laryngeal mask, shows: as shown in Figure 1, airway tube 2 and jointing 3 are original papers independently, and both cooperate by agglutinating mode, can cause the joint portion rough like this, form ladder easily, can damage be arranged to air flue inwall mucosa during insertion, and easily come off; In addition, the flexibility of airway tube 2 is big, does not meet human engineering, and resilience force is big when inserting trachea.
The utility model content
The purpose of this utility model provides a kind of laryngeal mask airway device, and to the damage of air flue inwall mucosa, and Stability Analysis of Structures provides flexibility suitable airway tube simultaneously in the time of can reducing to insert.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of laryngeal mask airway device, comprise: catheter adapter, airway tube, jointing, air bag, gas tube, pilot balloon and check valve, catheter adapter is arranged on an end of airway tube, the airway tube other end is connected with air bag by jointing, gas tube is connected with air bag, and pilot balloon and check valve are arranged on the gas tube; It is characterized in that described airway tube and jointing are one-body molded.
Wherein, described airway tube is an arcuation, and its radius of curvature is chosen between 140～160mm.
Airway tube in the laryngeal mask that this utility model provides and jointing are integrated, can guarantee smoothness, and reliable in structure, compared with prior art has following beneficial effect: when inserting and extracting, damage to air flue inwall mucosa is little, facts have proved that the painstaking effort system response is little during operation, the probability of patients after surgery throat pain is very little; In addition, the improvement of endotracheal tube radius of curvature makes and reduces patient's misery simultaneously by easier the carrying out of operation.
Description of drawings
Fig. 1 is a kind of sketch map of existing laryngeal mask airway device;
Fig. 2 is the integrated airway tube that this utility model adopted and the sectional view of jointing;
The laryngeal mask schematic representation of apparatus that Fig. 3 provides for this utility model.
The specific embodiment
As shown in Figure 2, it is integrated that this utility model adopts airway tube 21 and jointing 31, can guarantee smoothness, and Stability Analysis of Structures; And the radius of curvature of control airway tube 21 is between 140～160mm, and by clinical verification, this range of curvature radius is based on that human engineering and clinical practice obtain.As shown in Figure 3, the laryngeal mask airway device that this utility model provides comprises: catheter adapter 1, integrated airway tube 21 and jointing 31, air bag 4, gas tube 5, pilot balloon 6 and check valve 7, catheter adapter 1 is arranged on an end of airway tube 21, jointing 31 is connected with air bag 4, gas tube 5 is connected with air bag 4, and pilot balloon 6 and check valve 7 are arranged on the gas tube 5.
Claims (2)
1. laryngeal mask airway device, comprise: catheter adapter, airway tube, jointing, air bag, gas tube, pilot balloon and check valve, catheter adapter is arranged on an end of airway tube, the airway tube other end is connected with air bag by jointing, gas tube is connected with air bag, and pilot balloon and check valve are arranged on the gas tube; It is characterized in that described airway tube and jointing are one-body molded.
2. laryngeal mask airway device according to claim 1 is characterized in that, described airway tube is an arcuation, and its radius of curvature is chosen between 140～160mm.
