Description

Adjustable intubation aid

This invention relates to an adjustable intubation aid, in particular to an adjustable intubation aid for easily inserting an endotracheal tube into a patient's trachea.

According to the report, when a patient wants to undergo intubation treatment, medical staff will insert an endotracheal tube through the patient's mouth, throat and glottis to enter the deep part of the trachea, and assist with a ventilator to solve problems such as difficulty breathing, weak breathing or respiratory failure.

Since endotracheal tubes are generally made of softer medical materials, during intubation, the endotracheal tube made of soft materials must be passed through the patient's mouth, through the throat and avoid the glottis to enter the deep part of the trachea. Due to the curvature of the throat and trachea of the human body, the intubation work is difficult and often takes a lot of time for medical staff. Especially when the patient is in critical condition and urgently needs emergency rescue, it is even more important to complete the intubation work quickly.

The Republic of China Publication No. 201509450 discloses an "intubation assisting device" suitable for inserting an endotracheal tube into a patient's trachea. The endotracheal tube includes a tube body and a distal end. The intubation assisting device includes a movable tubular cleaning rod, a grip controller, and a viewing device. The movable tubular cleaning rod is flexible and has a head, a body, a tail section, and a pair of cracks passing through the body and the tail section along a self-axis. The tail section is divided into a first and a second driven piece by the pair of cracks. The viewing device has a slender body and a viewing head. The slender body and the viewing head can slide forward and backward along the axis and pass through the grip controller and an inner hole of the head section of the movable tubular cleaning rod. When the first and second driven pieces produce relative movement, the head section can simultaneously drive the distal end of the endotracheal tube and the viewing head to swing.

The above-disclosed "intubation assisting device" patent has a complex structure and is inconvenient to operate. In particular, the cleaning and disinfection work after use becomes troublesome and inconvenient. Therefore, it has not been widely used by medical staff so far.

In view of this, how to easily and quickly insert the endotracheal tube into the patient's trachea, the conventional intubation assist device does need to be improved.

In order to solve the above problems, the main purpose of this invention is to provide an adjustable intubation aid that can help workers easily and quickly insert an endotracheal tube into the patient's trachea.

The second purpose of this invention is to provide an adjustable intubation aid with low cost, so that the adjustable intubation aid can be discarded after use, so as to reduce the cleaning and disinfection work after use, so as to reduce the workload of workers and reduce cross-infection.

The directions or similar terms described in the entire text of this work, such as "front", "back", "left", "right", "upper (top)", "lower (bottom)", "inside", "outside", "side", etc., are mainly for reference to the directions of the attached drawings. Each direction or similar terms are only used to assist in the description and understanding of the various embodiments of this work, and are not used to limit this work.

The quantifiers "one" or "a" used in the components and parts described in this work are only for the convenience of use and to provide the general meaning of the scope of this work; in this work, they should be interpreted as including one or at least one, and the concept of a single number also includes the plural case, unless it is obvious that it means otherwise.

The adjustable intubation aid of the invention may include: a body having a first end and a second end, the arc formed between the first end and the second end having an inner arc surface, and the second end having a head; a control string having a first end and a second end, the first end being connected to the inner arc surface of the body, the second end having a pull portion, the pull portion having an open groove, the open groove being used for the body to be placed through the opening; and a probe made of a soft material, the probe covering the first end of the body.

Accordingly, the adjustable intubation aid of the invention can be inserted into the hollow passage of the endotracheal tube. Thus, when the deep end of the endotracheal tube touches the wall of the laryngeal orifice and forms an obstruction and cannot be smoothly advanced, the worker can pull the pull portion to make the probe bend and deform toward a curvature center of the inner arc surface so that the deep end of the endotracheal tube is no longer obstructed, and the endotracheal tube and the deep end can be easily and smoothly advanced to the airway. The adjustable intubation aid of the invention can be discarded after use, which has the effect of reducing the cleaning and disinfection work after use, thereby reducing the workload of the worker and reducing cross infection.

The main body is designed to have a cross-sectional size that gradually decreases from the second end toward the first end. In this way, the main body can have appropriate strength and the probe can be easily bent and deformed.

The body forms a diameter difference portion adjacent to the first end by means of the diameter difference. Thus, the probe of the body can be more easily bent and deformed by the diameter difference portion.

The first end of the control string is connected to the inner arc surface between the diameter difference portion and the first end of the body. In this way, the probe of the body has the effect of being easier to bend and deform.

The control string and the main body are made by an integrated molding method. In this way, the control string and the main body can be firmly connected, and there will be no separation between the two.

The connection between the control string and the main body is to first make one of the components of the control string or the main body, and then place the manufactured component into a mold for forming the other component for overmolding. In this way, the control string and the main body can be firmly connected, and there will be no separation between the two.

At least one groove wall of the opening groove has a protruding protrusion to reduce the distance between the two groove walls of the opening groove. This can prevent the body from coming out of the opening.

The probe is covered by placing the formed body into a molding mold and then injecting the probe. In this way, the probe can cover the first end of the body, which can prevent the probe from contacting the patient's throat wall and causing damage.

The adjustable intubation aid of the invention further includes an endotracheal tube, which has a hollow channel and an in-depth end and an operating end. Thus, the adjustable intubation aid of the invention can make the endotracheal tube easily and smoothly continue to advance, so as to penetrate into the patient's airway.

The probe extends through the hollow passage of the endotracheal tube. Thus, the adjustable intubation aid of the invention can make the endotracheal tube easily and smoothly continue to advance, so as to penetrate into the patient's airway.
