Description

[Detailed explanation of the invention] "Industrial application field" This invention is used to anesthetize the patient and use a bronchial fiberscope to inspect the endotracheal tube in order to ensure the patient's breathing during surgery and treatment. The present invention relates to a mask for an endotracheal tube that is inserted into the trachea.

"Prior Art" As is well known, during endotracheal intubation due to anesthesia, it is difficult to expand the larynx using a normal laryngoscope, and endotracheal intubation under direct vision is sometimes impossible. in this case,
Using a bronchial fiberscope, pass the scope through the endotracheal tube, extend the tip of the scope with the tip of the tube, and perform intubation while confirming the position within the trachea. However, such intubation takes time and must be performed under controlled breathing using a mask.

Conventional endotracheal intubation masks of this type include an endotracheal intubation adapter, which is used as a guide when intubating an endotracheal tube into a patient's trachea using a bronchial fiberscope, and is attached to a normal mask. It is known that it can be used as When assuming a patient for whom endotracheal intubation is difficult, an endotracheal intubation adapter is attached to the mask, and the endotracheal tube is inserted into the trachea using the endotracheal fiberscope using the endotracheal intubation adapter. That's what I do.

``Problem to be solved by the invention'' However, in the case of the conventional endotracheal tube mask described above, it is difficult to attach the endotracheal tube to a normal mask and insert the endotracheal tube through the endotracheal intubation adapter. This is inserted into the patient's trachea using a bronchial fiberscope, but some patients may have difficulty in intubation when inserting the endotracheal tube. An adapter for endotracheal intubation must be attached, which is cumbersome to attach and detach, and the structure is such that the adapter is attached to the mask, making the mask larger, bulkier, and heavier. However, it is difficult to secure the device to the patient's face, making it difficult to perform endotracheal intubation, and it is also expensive.

This invention was made in view of the above-mentioned problems, and aims to provide a mask for endotracheal intubation that solves the above-mentioned problems of conventional masks.

"Means for Solving the Problem" In order to achieve the above-mentioned purpose, this invention provides a transparent cup-shaped mask body that covers the patient's lips and nose area, and anesthetic gas is placed at a predetermined position on the mask body. An introduction port is formed, and an insertion port for the endotracheal tube is formed on the front side of the mask body, and an insertion hole having a diameter slightly smaller than the outer diameter of the endotracheal tube is formed on the outer surface of the insertion port. In addition to providing a formed membrane body, a valve leaf that can be opened only from the outside to the inside of the mask main body is provided on the inner surface side of the insertion port.

``Function'' According to the endotracheal intubation mask of this invention, anesthetic gas is introduced into the mask body from the anesthetic gas inlet to increase the internal pressure within the mask body, thereby causing the valve leaflet to move inside the insertion port. When in close contact, the insertion port is closed and used as an anesthesia mask. In addition, by simply inserting the endotracheal tube through the insertion hole of the membrane body through the insertion hole formed in the mask body, the endotracheal tube can be inserted while pushing the valve leaflet provided on the inner surface of the insertion port inward. It is inserted into the mask and held in a tight fit state in the insertion hole of the membrane body, and is used as a mask for endotracheal intubation.

"Example" This invention will be described below with reference to the drawings. 1st
Figures 3 through 3 show an embodiment of the endotracheal intubation mask of the present invention.

Reference numeral 1 in the figure is an endotracheal intubation mask for intubating an endotracheal tube into the trachea through the patient's mouth or nose to ensure the patient's breathing during surgery or treatment. This endotracheal intubation mask 1 includes a mat part 2 that closely contacts the face near the outer periphery of the patient's lips and nose (not shown), and a mat part 2 that is fixed to the upper surface side of the mat part 2 to cover the lips and nose. It consists of a transparent cup-shaped mask body 3.

In this embodiment, the mat portion 2 is a donut-shaped rubber balloon provided with an air port 2a,
A rubber balloon is inflated by blowing air into it. The cup-shaped mask body 3 has a front surface that is flat with respect to the face, and a circular anesthetic gas inlet 4 is formed on the side of the mask body 3.
There is an insertion port 5 for the endotracheal tube on the front of the mask body.
is formed.

Further, on the outer surface of the insertion port 5, a membrane 7 made of a rubber sheet and having an insertion hole 7a with a diameter slightly smaller than the outer diameter of the endotracheal tube 6 (see Fig. 3) is glued around the entire circumference. and the insertion port 5
The inner surface of the mask body 3 can be opened only from the outside to the inside, that is, a valve membrane 8 made of a rubber sheet and having the function of a check valve is bonded to one end side of the insertion port 5. It has a fixed structure.

Next, the operation of the endotracheal intubation mask configured as described above will be explained.

In the endotracheal intubation mask 1 of this embodiment, by introducing anesthetic gas into the mask body 3 from the anesthetic gas inlet 4, the valve leaflets 7 are caused to move inside the mask body 3 due to internal pressure, as shown in FIG. The insertion port 5 is closed in a state in close contact with the inside of the insertion port 5, and is used as an anesthesia mask. Further, as shown in FIG. 3, the endotracheal tube 6 is inserted through the insertion hole 7a of the membrane body 7 from the insertion port 5 on the front side of the mask body 3.
Just insert the endotracheal tube 6 into the insertion port 5.
is inserted into the mask body 3 while pushing and bending the valve membrane 8 provided on the inner surface side of the membrane body 7 inward, and is held in a tight fit state in the insertion hole 7a of the membrane body 7,
Used as a mask for endotracheal intubation.

Therefore, in the endotracheal intubation mask of the present invention, the endotracheal tube 6 can be inserted into the mask body 3 from the insertion port 5 even in the case of a patient for whom endotracheal intubation is difficult when inserting the endotracheal tube. It can be easily used as a mask for endotracheal intubation by simply inserting it. Furthermore, in this state, it can be used simultaneously as an anesthesia mask and an endotracheal intubation mask, and the endotracheal tube can be intubated into the trachea while administering anesthesia. This endotracheal intubation mask has a simple structure, with just a membrane and a valve leaflet attached to the insertion port of the mask body, so it has a simple shape, is lightweight, does not add bulk, and is comfortable for patients. It is easy to fix on the face and can be made at low cost.

In the above embodiment, a donut-shaped rubber balloon was used for the mat portion 2, but the balloon is not limited to this, and any material that fits well and adheres to the face, such as a sponge, may be used. . Moreover, the shape of the mask body may be any shape as long as it covers the face.
