Description

Video airway endscope

TECHNICAL FIELD The present invention relates to a video airway intubator, and more particularly, to a video airway intubator, which makes it easy to observe the intubation path of a tube for ventilation.

In general, tracheal insertion tubes (hereinafter referred to as 'tubes') are used to artificially breathe in patients who cannot breathe on their own.

For example, in order to perform anesthesia and artificial respiration during surgery, or to artificially breathe a patient who is in an unconscious state due to an accident, the tube is inserted into an organ to supply air or an anesthetic.

In this case, since the tube is disposed in the respiratory part of the human body, care must be taken when intubating the tube, and care must be taken not to transmit pain to the patient before intubation of the tube is performed.

At this time, an intubator is provided to intubate the tube into the trachea of the patient.

The intubator is provided so that the tube is inserted into the trachea of the human body, and the insertion path of the tube can be observed from the outside of the human body, and the tube is inserted into the trachea by the guide of the intubator.

Hereinafter, a conventional intubator will be described with reference to FIG. 1.

As shown in FIG. 1, the intubator is composed of a main body 10, a stylet 20, and a lens 30.

The main body 10 includes a power supply device, and the stylet 20 and the lens 30 are installed at one side and the other side of the main body 10, respectively.

The stylet 20 is a portion to be inserted into the organ of the human body together with the tube 40, one end thereof is provided with a viewer 21 for showing the organ of the human body.

At this time, a plurality of optical fibers are installed inside the stylet 20, which are arranged around the viewer 21.

That is, when a separate light emitting device 50 is installed in the main body 10 to provide light, the light is emitted along the optical fiber to illuminate the organs of the human body.

Accordingly, the organs of the human body can be observed more clearly.

In addition, the lens 30 displays an organ of the human body photographed by the viewer 21, and is installed at the other side of the main body 10 as shown in FIG. 1.

Looking at the process of intubating the tube using a conventional intubator having such a configuration as follows.

After inserting the tube 40 to be inserted into the stylet 20 of the intubator, the tubelet 40 is inserted into the patient's trachea.

At this time, a separate light emitting device 50 is mounted on the main body 10 so that the optical fiber emits light.

At this time, the operator closes the eye to the lens 30 and observes the insertion path of the stylet 20 seen by the viewer 21 to treat the insertion of the stylet 20.

Thereafter, when the insertion of the stylet 20 into the trachea of the patient is completed, the stylet 20 is removed from the trachea of the patient.

At this time, the tube 40 is inserted into the trachea of the patient, and only the stylet 20 comes out.

Thereafter, by connecting a ventilator (not shown) to one end of the tube 40 exposed to the outside of the patient, the intubation treatment for the tube 40 is completed.

However, the conventional intubator has the following problems.

First, there was a problem that the operator is very uncomfortable as well as to secure the field of view by attaching the eye to the lens 30 to observe the insertion path of the stylet 20.

That is, the operator has to take care while looking at the surrounding environment as well as the insertion path of the stylet 20, and the field of view has been narrowed due to the conventional configuration of the lens 30.

Second, since the operator must close the eye to the lens 30, the distance between the patient and the operator is closer.

As a result, there was a risk that the operator would be infected from the patient.

Third, since a separate light emitting device 50 is required for irradiation of light, it is not only cumbersome for the treatment process but also has a problem of low economic efficiency.

In addition, since the indirect irradiation method, there was a problem that the brightness of the light falls.

Fourth, when bleeding occurs in the patient's organs or there is a foreign object, there was a problem that the viewer (21) is blocked by these to take a picture of the insertion path properly.

Fifth, there was a problem that the replacement for the tube 40 is not made efficiently.

That is, in the case of a critical patient, the tube 40 inserted into the trachea should be replaced periodically, because if the inserted tube 40 is left for a long time, the bladder constituting the tube 40 may be damaged.

In addition, replacement of the tube 40 is necessary because mucus, such as sputum, may occur in the patient's organs and cause the patient's organs to be blocked.

However, in the case of the conventional intubator, in order to replace the tube 40, there is a disadvantage that the existing tube 40 must be removed and started again from the beginning.

This not only lowered the efficiency of the tube 40 replacement procedure, but also resulted in patient pain.

Sixth, depending on the height of the operator, the operator must bend the back, in order to eliminate this inconvenience, the patient has to adjust the height of the lying bed, which also caused very troublesome and uncomfortable.
