Background

A laryngeal mask is a medical device for supraglottic ventilation that can be used to maintain breathing in an unconscious patient, such as a patient under general anesthesia, to establish a breathing passage for the patient. It is compared to endotracheal intubation, which requires a glottis pass through, for low flare, difficult airways may be difficult to insert in place, and the airways may be damaged after use by the patient. The laryngeal mask does not need other auxiliary appliances when in use, does not damage tissues such as oral cavity, teeth, air passages, vocal cords and the like of a patient, and is used more than an endotracheal tube in some developed countries and is in an increasing trend.

However, the laryngeal mask has problems in use, such as displacement if the position of the patient changes, or the laryngeal mask is accidentally touched by the doctor during the operation to cause the laryngeal mask to be displaced, so that anesthetic gas leaks; in addition, when the laryngeal mask is used, the patient may be agitated to bite the tube body of the laryngeal mask to ventilate when the patient is not enough in anesthesia amount or is about to recover, so that gas leakage is caused.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: comprising a gas-filled tube 1.

Wherein, one end of the inflation tube 1 is fixedly connected with an indicating air bag 5.

The indicating air bag 5 can be used for measuring when being inflated and fixed, and the phenomenon that an air passage is damaged due to overlarge inflation or falls off due to undersized inflation is avoided.

Wherein, one end of the indication air bag 5 is fixedly connected with a one-way valve 6.

Wherein, check valve 6 can carry out one-way admission when aerifing, avoids aerifing the in-process gas and spills.

Wherein, the other end of the inflation tube 1 is fixedly connected with a cuff 2.

Wherein the cuff 2 can serve as a relay and can also be replaced after use of the airway tube 3.

Wherein, one end of the cuff 2 is sleeved with an airway tube 3.

Wherein the airway tube 3 can deliver gas to establish a breathing passage for the patient.

Wherein, the both sides of the surface of one end of the ventilation catheter 3 are fixedly connected with bite-blocks 7, and the surface of the bite-block 7 is fixedly connected with a fixing belt 8.

Wherein, the bite block 7 can solve the problems of fracture and bite of the ventilation catheter, and the fixing band 8 can solve the problem of displacement of the laryngeal mask in the using process.

Wherein, one end of the ventilation catheter 3 is fixedly connected with a joint 4.

Wherein the joint 4 can be connected with the laryngeal mask and is convenient to replace after use.

Furthermore, the cuff 2 is triangular, one corner of the cuff is a socket, and one side of the cuff is fixedly connected with the inflation tube 1.

Wherein the socket can be replaced after use of the airway tube 3 as a transition.

Furthermore, the surface of the bite block 7 is provided with a plurality of holes.

Wherein, can be according to the weight of patient and the head type system in different trompils, satisfied different patients' operation requirement.

Further, the fixing belt 8 and the bite block 7 are fixedly connected through an opening, and the fixing mode can be a knotting mode or a self-adhesion mode.

Wherein, connect the back more stable, avoid droing in the use.

Furthermore, an internal thread is arranged inside one end of the ventilation catheter 3, an external thread connector is arranged at one end of the connector 4, and the ventilation catheter 3 and the connector 4 are in threaded connection through the internal thread and the external thread connector.

Wherein, can be convenient for more change after using to be convenient for accomodate when not using more.

The working principle is as follows: when the laryngeal mask airway device is used, the airway tube 3 is in threaded connection with the connector 4, then the airway tube 3 is inserted into the cuff 2, the fixing bands 8 are tied in different holes of the bite block 7 according to the weight and the head shape of a patient, the using requirements of different patients are met, and the situation that the patient feels restless and bites the tube body of the laryngeal mask for ventilation when the patient is not enough in anesthesia amount or needs to wake up is avoided, so that gas leakage is caused.
