Description

Airway intubation system

The present invention relates to an airway intubation system, and more particularly, to an airway intubation device used to secure an airway of an emergency patient.

The airway intubation system is used to secure the airway of the patient through which oxygen, medicine, etc., and plays an important role in saving unconscious emergency patients. It consists of an airway intubation device inserted into the airway side of the patient and a syringe for injecting air therein for the safety of the patient.

The airway intubation device includes an airway intubation tube that is inserted into the patient's airway, which is a long, narrow tube formed with an inflatable baloon located at the distal end. When the airway is secured, the end of the airway intubation tube is inserted into the trachea of the patient through the laryngeal inlet (or glottic opening) through the patient's mouth.

Once the airway intubation is made, the balloon is inflated to maintain internal lining and tightness of the trachea, i.e. to prevent foreign objects from entering the lungs into the lungs.

On the other hand, such balloon expansion is performed after the airway intubation is correctly performed.

Conventionally, a stethoscope is used several times to confirm the correct intubation and the position of the airway intubation tube. Through this, the airway intubation device is correctly inserted into the airway and the end of the airway intubation device is located in the airway. You will be asked to check. Such a method has a problem in that a doctor spends a lot of time considering the situation of the emergency patient.

Failure of the airway intubation occurs for a variety of causes, and in some cases, as the airway intubation tube enters the esophagus behind the airway.

In the event of an airway intubation failure, the doctor will attempt to intubate again and use a stethoscope to confirm the correct intubation.

Although the oxygen supply should be made very quickly after the airway is secured by the emergency patient, if the patient spends a lot of time to determine the correct airway intubation, it can greatly affect the patient's life. There is an urgent need to shorten the time to do this.

In order to solve the problems of the prior art as described above, the present invention is to propose an airway intubation system that can quickly and easily determine whether the correct airway intubation.

The rear open end 21 may comprise an adapter 23 for connecting to an oxygen supply device, such as a medical gas supply or anesthesia, an oxygen supply or other aeration device or ventilator.

The flexible tube 22 is comprised of a flexible, semi-rigid, soft plastic material that is not limited to polyethylene, polypropylene, or the like to facilitate airway intubation.

In addition, the flexible tube 22 has a first air passage A serving as a movement passage to the airway side of the air introduced from the respirator or the like, and an air movement passage from the syringe to the expansion portion 24 to be described below. Two air passages B are provided.

Meanwhile, the airway intubation device 20 includes an expansion part 24 (ballon or curf) expanded by air introduced from the outside after airway intubation, and an anterior open end 25 inserted into the airway 6 part during airway intubation. can do.

The inflation portion 24 prevents air from leaking between the flexible tubes 22 after airway intubation, and further prevents foreign matter in the esophagus 4 or airway 6 from entering the lungs.

On the other hand, in the direction of the rear open end of the inflation section 24, a flow valve 26 is provided which is connected to an air injection means such as a syringe 28. The flow valve 26 passes air only in one direction and blocks air in the reverse direction, and may have a structure as shown in FIGS. 4 to 5.

As shown in FIGS. 4-5, the flow valve 26 includes a ball 48 connected to the bias spring 47 to pass or block the air injected through the opening 41.

Air injected into the flow valve 26 is supplied through the air line 27 to the expansion portion 24 along the second air passage B of the flexible tube 22.

Meanwhile, as shown in FIG. 3, the light emitting portion 30 is provided at a predetermined position of the airway intubation device 20, preferably at the front open end 25.

3 is an enlarged view of FIG. 2C.

Preferably, the light emitting portion 30 is located on the front wall of the balloon 24 of the flexible tube 22 and connected to the light emitting portion so that it can be best identified in the neck skin without disturbing air flow by an oxygen respirator or the like. 31 may be arranged to be connected to the connection terminal of the flow valve by traveling with the second air passage (B).

The electric wire 31 for supplying power to the light emitting part 30 extends toward the flow valve 26 along the second air passage B and the air line 27 described above at the light emitting part 30 side.

After the airway intubation, the light emitting unit 30 is turned on by supplying power to the light emitting unit 30 of the airway intubation device 20.

According to the present invention, whether the airway intubation device 20 is correctly inserted into the airway 6 is confirmed through the light emitting unit 30.

From the airway (6) to the skin side of the neck is approximately 1cm thick, when the light emitting unit 30 is turned on, it is possible to check whether the light emitted from the skin side of the neck thyroid cartilage (7) directly below. .

According to the present invention, there is provided a light emitting portion 30 having an intensity that can penetrate the skin thickness of the neck within about 1cm, and further provides a green light contrasted with the color of the skin so as to easily check whether the light emission The light emitting unit 30 for emitting light may be provided. However, the present invention is not limited to green light, and the light wavelength of the light emitting unit 30 is not limited as long as it can be seen through the skin.

 In the present invention, to limit the intensity of the light irradiated from the light emitting unit 30 is to prevent the light transmitted to the side of the skin when the airway intubation device 20 is inserted in the wrong position.

When the airway intubation device 20 is inserted into the esophagus 4, the skin thickness from the skin side of the neck to the esophagus exceeds 1 cm. According to the present invention, the intensity of light irradiated from the light emitting part 30 is limited. In this case, even if the light emitting unit 30 is turned on, it is impossible to check whether the light is emitted from the skin side of the neck.

According to the present invention, the insertion of the airway intubation device 20 determines whether accurate airway intubation is made through the lighting of the light emitting unit 30, and furthermore, the position of the front open end 25 of the airway intubation device 20 can be accurately determined. Can be.

Therefore, it is possible to immediately know the failure of the airway intubation that is frequently trial and error in the emergency situation (that is, when the intubation is inserted into the esophagus rather than the airway), which can greatly help the life of the emergency patient.

In FIG. 3, the light emitting unit 30 is illustrated as being disposed on the side of the balloon 24. However, the light emitting unit 30 is not limited thereto, and the light emitting unit 30 may be applied without limitation if the light emitting unit 30 is adjacent to the airway 6. It will be appreciated by those skilled in the art that the position of the light emitting portion 30 can be located anywhere on the inner circumferential surface of the flexible tube 22 so that the light emitting unit 30 can be located within the airway without limitation.

Meanwhile, according to an exemplary embodiment of the present invention, a process of supplying power to the light emitting unit 30 is performed at the same time as the airway intubation.

4 to 5 illustrate various structures for supplying power to the light emitting unit 30.

4 to 5, the airway intubation system according to the present invention may include a syringe 28 equipped with a power supply 40.

The present invention allows the power supply 40 and the light emitting portion 30 mounted on the syringe 28 to be electrically connected at the same time that the syringe 28 is connected to the flow valve 26.

As described above, the air inlet 44 of the syringe 28 is fitted to the flow valve 26 to prevent foreign matter or the like from entering the lungs after the flexible tube 22 is inserted into the airway 6, As the piston of the syringe 28 is compressed, air is injected into the expansion part 24.

At this time, as shown in Figures 4 to 5, the syringe 28 according to the present invention is provided with a configuration that can supply power to the light emitting unit 30 is faster and more convenient than using a separate external power supply device It is possible to supply power to the light emitting unit 30.

The method of supplying power to the light emitting unit 30 may be variously applied.

First, referring to FIG. 4, a connection terminal 43 connected to the power supply 40 of the syringe 28 is formed on one surface of the flow valve 26, that is, on the opening 41 side.

Here, the connection terminal 43 may be connected to the wire 31 extending from the light emitting part 30, and may have a shape protruding in a direction opposite to the inflow direction of air on one surface of the flow valve 26 as shown in FIG. 4. .

The protruding connection terminal 43 is located at a predetermined position of the syringe 28 when the air inlet 44 of the syringe 28 is fitted to the opening 41 side of the flow valve 26 for air injection. It is electrically connected to the formed power supply part 40.

On the other hand, as shown in Figure 4, the power supply 40 may be mounted in a predetermined housing (45). In this case, one side of the housing 45, that is, one side of the air injecting direction is formed with a groove-shaped connecting portion 46 into which the connecting terminal 43 may be fitted.

Here, the connecting portion 46 corresponds to the connecting terminal 43 when the air injecting portion 44 and the central axis of the opening portion 41 are in parallel, that is, when the air injecting portion 44 is fitted into the opening portion 41. It can be formed in the position to.

As shown in FIG. 4, in the case of providing the connecting terminal 43 and the connecting portion 46, power may be supplied to the light emitting portion 30 just before the syringe 28 injects air into the flow valve 26. Through this, it is possible to determine whether the airway intubation device 20 is correctly positioned in the airway 6.

On the other hand, Figure 5 is a diagram showing a power supply structure to the light emitting unit according to another embodiment of the present invention.

As shown in FIG. 5, in the airway intubation apparatus according to the present invention, a connection terminal 50 to which an electric wire 31 extending from the light emitting part 30 is connected is formed on one surface of the flow valve 26.

Here, unlike the illustrated in FIG. 4, the connection terminal 50 is not protruded from the flow valve 26, and may be formed in a closed curved surface (preferably circular) on one surface of the flow valve 26.

In this case, the connection terminal 50 may include a first connection terminal 51 corresponding to the positive electrode and a second connection terminal 52 corresponding to the negative electrode, between the first and second connection terminals 51 and 52. An insulating layer 53 for electrical insulation may be provided.

On the other hand, when the connection terminal 50 is provided as described above, the syringe 28 according to the present invention, as shown in Figure 5, the connection portion 54 formed on a predetermined position on the outer peripheral surface of the air injection portion 44 is formed do.

Herein, the connection part 54 formed in the syringe 28 is connected to the power supply part 40, and corresponds to the first connection part 55 and the second connection terminal 52 corresponding to the first connection terminal 51. The second connector 56 may be included, and an insulating layer 57 may be provided between the first and second connectors 55 and 56.

At this time, the connection terminals 51 and 52 formed on one surface of the flow valve 26 and the connection portions 55 and 56 and the insulation layer 57 formed on the outer circumferential surface of the air injection portion 44 are fitted with each other. It may be a closed curved surface of a size that can be bitten, and preferably each of the circular shape having the same diameter.

In such a configuration, since the direction in which the air injecting portion 44 is inserted into the opening portion 41 is not limited, power can be more conveniently supplied to the light emitting portion 30.

On the other hand, when a connecting terminal is provided on the flow valve 26 side and a means for connecting with the connecting terminal is provided on the syringe 28 side, it is necessary to confirm correctly that it is electrically connected correctly.

Since the light emitting unit 30 according to the present invention is inserted into the human body, it may not directly determine whether power is supplied to the light emitting unit 30, and there may be an error in determining whether accurate airway intubation is performed.

For example, if the light emitting unit 30 is not turned on due to an incorrect connection between the light emitting unit 30 and the power supply unit 40 even though the airway intubation is correctly performed, light does not penetrate from the side of the skin of the neck. Intubation may be judged to be incorrect.

Such an incorrect connection may occur due to a lack of electricity remaining in the power supply 40 or a poor contact between the connection terminal and the connection portion.

In order to prevent this, according to the present invention, a notification means 58 is provided on one side of the airway intubation device 20.

Here, the notifying means 58 may include an acoustic means for outputting sound or an LED for emitting light according to the electricity supply.

The notification means 58 according to the present invention is connected to the wire 31 extending from the light emitting portion 30. In this way, when the notification means 58 is provided, electricity is supplied to the notification means 58 only when the above-described connection terminal and the connection part connected to the power supply part 40 are correctly contacted.

Accordingly, the doctor can immediately check whether the correct electrical connection is made through the alarm sound or the light output from the notification means 58 after the power supply attempt.

As shown in FIG. 6, after confirming the electrical connection, the doctor confirms whether the airway intubation device 20 is correctly inserted through the neck skin observation of the patient, and confirms the end position of the airway intubation device. After the determination, air is injected into the expansion part 24 by applying pressure to the piston of the syringe 28.

According to the present invention can immediately confirm the failure of the airway intubation undergoing a lot of trial and error in an emergency situation can greatly contribute to the maintenance of life of emergency patients.

On the other hand, while the power supply is described as being mounted to the syringe, those skilled in the art will understand that it may be possible to provide only the connection portion connected to the power supply in a position adjacent to the air inlet.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention.
