Problems solved by technology

When doctors use a flexible laryngeal mask, they often judge whether the laryngeal mask fits the pharynx cavity through experience. Since they cannot directly and accurately judge, the laryngeal mask may shift, leak, and fold back, which may cause users to experience Flatulence, severe regurgitation or aspiration, reducing the effectiveness of the laryngeal mask airway

Embodiment 1

[0032] see figure 1 and figure 2 , this embodiment provides a visual laryngeal mask with a bending function, which includes a flexible ventilation tube 1, a mask part 2 formed at the distal end of the flexible ventilation tube, and a visualization device; The ventilation cavity extending from the distal end, the flexible ventilation tube 1 is equipped with a spring 3 inside the tube wall so that the ventilation tube can be bent and deformed. In this way, it can be adapted to some special diagnosis and treatment patients by changing the placement position and bending angle of the flexible ventilation tube 1 Situations, such as for patients undergoing facial surgery, due to surgical needs, the ventilation tube needs to be moved to the corner of the mouth or other positions without shifting the position of the air bag. The traditional plastic ventilation tube cannot achieve displacement, but the ventilation tube provided by this embodiment Then effectively solve above-mentioned...

Embodiment 2

[0051] see figure 1 , this embodiment provides a visual laryngeal mask system, the visual system includes the visual laryngeal mask described in Embodiment 1 above, the difference is that the visual device is structurally deformed; specifically,

[0052] The visual device includes a first visual device and a second visual device, and the structure of the first visual device and the second visual device refers to the visual device involved in CN110694156A; the first visual device and the second visual device Both have:

[0053] A camera assembly, the camera assembly imaging through the first observation window and the second observation window;

[0054] A connecting wire 55, the connecting wire extends from the near end toward the far end, and the far end of the connecting wire is connected with the camera assembly

[0055] connected, the remote end of the connection line is connected to a display screen;

[0056] Handle 56, the handle is connected with the connection line, ...

Abstract

The invention aims to provides a visual laryngeal mask with a bending function. The visual laryngeal mask includes a flexible vent tube, a mask part and a visual device, wherein the mask part is arranged at the distal end of the flexible vent tube, a vent cavity which extends from the proximal end to the distal end is formed by the vent tube, and a spring is installed inside the tube wall of the flexible vent tube, so that bending deformation of the vent tube is realized; the mask part includes a bowl body and a capsule body, the capsule body is arranged on the bowl body, and the bowl body extends from the proximal end to the distal end; the bowl body has a ventral surface and a back surface which are opposite, a hole which communicates with the vent tube is formed in the ventral surface of the bowl body, and the visual device comprises a first camera assembly, a second camera assembly and a display member; and the first camera assembly is arranged at the ventral surface of the bowl body, the second camera assembly is arranged at the distal end of the bowl body, and the display member is used for displaying images of the first camera assembly and second camera assembly.

Description

technical field [0001] The invention belongs to the field of visual medical equipment, in particular to a bendable laryngeal mask with a visual function. Background technique [0002] The flexible laryngeal mask is a supraglottic artificial airway device specially designed for head, neck and upper torso surgery. The mask is easy to operate, less respiratory tract irritation, stable hemodynamics, and less postoperative complications, and the reinforced endotracheal tube has the advantages of bendability, bending resistance, and no interference with the surgical field. , the fixed position is flexible, leaving a large space for doctors to operate in the oral cavity and head and neck, and it has less damage to the patient's oropharynx and throat, so it can be widely used clinically. When doctors use a flexible laryngeal mask, they often judge whether the laryngeal mask fits the pharynx cavity through experience. Since they cannot directly and accurately judge, the laryngeal ma...
