Description

Visual laryngeal mask with suction and pressure measurement functions

Technical Field

The utility model relates to a medical instrument, in particular to a laryngeal mask.

Background

To maintain the respiratory ventilation of a general anesthesia patient, a breathing channel must be established. The traditional approach is to use an endotracheal tube. But tracheal intubation has disadvantages: firstly, it is difficult to insert the tube into the trachea quickly and properly, since this is a highly skilled procedure, often with the aid of a visual laryngoscope or the like, and must be performed by a skilled operator. The beneficial effect of this approach is therefore not apparent in some situations where it is desirable to establish a breathing pathway in the patient as quickly as possible in order to strive for treatment time; secondly, the tracheal intubation is easy to cause hemodynamics fluctuation, throat pain or laryngeal spasm and the like in the intubation process, and certain potential safety hazards exist.

Laryngeal masks have been developed to address the above problems. The application of the laryngeal mask brings great convenience to clinical anesthesia, simultaneously reduces the pain of a patient in tracheal intubation, and reduces the throat complications of the patient.

The external structure of the traditional laryngeal mask comprises a breathing joint for gas exchange and a gas injection port for inflating a balloon in the laryngeal mask, but the traditional laryngeal mask lacks the real-time monitoring of the conditions in the trachea of a patient and the accuracy of controlling the pressure of the balloon.

Disclosure of Invention

In order to solve the above problem, the utility model provides a following scheme:

a laryngeal mask comprises a mask body, an air bag, a laryngeal mask air pipe and an air bag pressurization pipe, wherein one end of the laryngeal mask air pipe is communicated with the top end of the mask body, the air bag pressurization pipe is communicated with the air bag, the air bag is annularly arranged on the outer ring of the lower end of the mask body, a probing hole is formed in the inner wall of the mask body, a camera is arranged in the probing hole, and a pressure sensor is arranged in the air bag.

Furthermore, the cover body side wall is provided with a camera wire channel, and the camera wire channel is connected with the cover body side wall through one end and the other end and extends along the laryngeal mask trachea.

Further, the pressure sensor transmits data through wireless signals.

Furthermore, a sealing ring is arranged between the camera and the probing hole.

Further, the inner wall of the air bag is provided with a fixing sleeve for mounting the pressure sensor.

Furthermore, the exploratory hole is positioned on the side wall of the mask body and close to the air bag part, and the camera can shoot the internal condition of the laryngeal mask after the camera is placed in the exploratory hole.

Further, the camera is a rotatable camera.

The utility model discloses a patient's trachea inside condition is observed to the camera, through the accurate pressure to the accuse gasbag of pressure sensor, more easily to the internal situation of accuse patient and increase patient throat and tracheal comfort level, reduce patient throat or tracheal harm.

Detailed Description

The present invention will now be described in detail with reference to the accompanying drawings:

example 1: as shown in fig. 1, a laryngeal mask comprises a mask body 1, an air bag 2, a laryngeal mask air pipe 3 and an air bag pressurization pipe 4, wherein one end of the laryngeal mask air pipe 3 is communicated with the top end of the mask body 1, the air bag pressurization pipe 4 is communicated with the air bag 2, the air bag 2 is annularly arranged on the outer ring of the lower end of the mask body 1, a probing hole is formed in the inner wall of the mask body 1, a camera 5 is arranged in the probing hole, and a pressure sensor 6 is arranged in the air bag 2.

Further, the lateral wall of the cover body 1 is provided with a camera wire channel 7, and one end of the camera wire channel 7 is communicated with the side wall of the cover body 1 and the other end is attached to the lateral wall of the cover body and extends along the laryngeal mask trachea 3.

Further, the pressure sensor 6 transmits data by wireless signals.

Further, a sealing ring is arranged between the camera 5 and the probe hole.

Further, the inner wall of the air bag 2 is provided with a fixing sleeve for mounting a pressure sensor 6.

Furthermore, the exploratory hole is positioned on the side wall of the cover body 1 and close to the air bag 2, and the camera 5 is arranged in the exploratory hole, and then the lens of the camera 5 can irradiate the condition in the cover body 1.

Furthermore, the camera 5 is a rotatable camera, so that whether the laryngeal mask is well aligned and whether excessive secretions in the trachea need to be cleaned can be observed.

The utility model discloses a camera 5 observes the inside condition of patient's trachea, and is accurate through pressure sensor 6 to the pressure of accuse gasbag 2, reduces patient's throat or tracheal harm to the internal situation of accuse patient and increase patient's throat and tracheal comfort level more easily.
