The trachea cannula is a technique that a special trachea catheter is placed into a trachea through a glottis, and is called as the trachea cannula, which can keep the smooth of an airway, ventilate and supply oxygen and perform respiratory tract suction operation. The emergency trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction.

In the prior art, the trachea is deeply inserted into the respiratory tract, the trachea is in a blind insertion state, the operation is completely carried out by depending on the experience and judgment of medical staff, and even the intubation is difficult when the respiratory tract is blocked and the like.

Meanwhile, the blind insertion method is not beneficial to sucking out the foreign matters under the conditions of respiratory tract inflammation, foreign matter blockage and the like.

Some existing trachea cannula devices have the advantages that a miniature camera is additionally arranged in a trachea to capture the scene of the front end of the cannula and facilitate treatment of a focus by a doctor during intubation, for example, a patent number CN201820083412.X 'visible trachea cannula mechanism' comprises a cannula main body, a jack is formed in a first selected area of an annular wall of the cannula main body, a first auxiliary tube is formed in the jack, the wall thickness of the first selected area is at least larger than that of a second selected area, and an image collector is arranged at the front end in the auxiliary tube. The image collector is connected with an image receiver outside the auxiliary pipe through the image fiber of the auxiliary pipe.

However, the mechanism of the visual trachea cannula is still simpler, and the auxiliary light source and the camera in front of the camera are easily blocked by the sludge in the trachea, so that the image acquisition effect is poor.

In addition, after the front end of the tracheal cannula reaches the focus, the front end of the tracheal cannula cannot be well fixed in the negative pressure suction process, and the suction point is easy to deviate.

Disclosure of Invention

The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a visual trachea cannula comprises head, body, appearance ware mouth, tongue clamp plate, installs display screen fixed bolster and display screen on the tongue clamp plate, its characterized in that: the head of the visual trachea cannula is provided with a balloon, the center of the tube body is a negative pressure suction channel, a cable channel, an inflation channel, a balloon vent hole and a developing tank are arranged in the tube body, a miniature camera module and a miniature lighting module which are provided with a miniature image sensing chip and a miniature lens are further arranged in the head, and an inflation port and a Murphy's hole are formed beside the miniature lighting module.

The air charging port is connected with the Ruhr joint through the air charging channel.

The miniature lighting module is an LED light source arranged in the head, and the LED light source is arranged on two sides of the miniature lens in the head.

The display screen passes through the cable all the time with miniature camera module be connected to the display screen is through wired or wireless connection computer or mobile terminal equipment.

The tube body also comprises a transfusion channel and an illumination channel, wherein the illumination channel is a fiber channel.

Compared with the prior art, the utility model has the advantages of: the head of the tracheal cannula has good fixing effect. When the visual trachea cannula is inserted into a trachea, the head of the visual trachea cannula reaches a focus, the balloon is inflated through the balloon vent hole to expand the visual trachea cannula, the trachea is clamped, and the head of the visual trachea cannula is fixed. When the negative pressure suction is carried out, the head of the tracheal cannula is prevented from displacing.

An air charging channel is arranged near the micro lens and the micro lighting module, high-pressure air flow is pushed outwards, so that the sediment of an air pipe is prevented from being attached to the camera and the micro lighting module, and a good imaging effect is ensured. In addition, when the balloon is inflated to block the trachea, the inflation channel can also provide oxygen required by respiration for a patient.

It also has a spare fluid-conveying channel, which can reduce the blockage degree of the sludge and lubricate the air pipe by inputting lubricant. Is beneficial to the negative pressure suction operation.
