Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary device used for bleeding air from a cuff of a laryngeal mask used for securing an airway in anesthesia, intensive care and emergency care.

[0002]

2. Description of the Related Art As shown in FIG. 1, a laryngeal mask 1 is formed by attaching a hollow cuff 3 to the periphery of an egg-shaped mask body 2 and communicating with a breathing hole 2a formed in the mask body 2. The respiratory tube 4 is connected to the tube connecting portion 4a on the rear surface, and the air tube 5 for injecting air is connected to the air tube connecting portion 5a at the rear end of the peripheral edge of the cuff 3. In this state, the laryngeal mask 1 is inserted into the larynx of the patient, and then the cuff 3 is inflated to cover the larynx with the mask 1 to secure an airway. In addition, there are a plurality of types of laryngeal masks having different sizes, and they are used properly according to the physique of the patient. Conventionally,
As described above, the cuff 3
The air in the cuff 3 was evacuated by a syringe connected to the air tube 5 while pressing the airbag against a flat portion such as a table.

[0003]

[Problem to be solved by the invention] By the way, the cuff 3
As shown in FIG. 1B, it is necessary to constrict the back of the mask body 2 so as to warp, but if the cuff 3 is simply vented, the cuff 3 may be kinked or wrinkled. The cuff 3 cannot be properly constricted, and it may be difficult to insert the laryngeal mask 1 into the larynx. The present invention has been made in view of the above circumstances, and has as its object to provide an assisting device that can properly squeeze the cuff 3.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is an auxiliary device used for deflating a cuff provided on the periphery of a mask of a laryngeal mask by bleeding air. It is characterized by comprising at least one of a female member having a concave contact surface conforming to the front shape of the cuff in a folded state, and a male member having a convex contact surface conforming to the rear shape of the cuff. .

[0005]

The cuff contracts into a shape along the contact surface by pressing the contact surface of the mold member against the cuff and bleeding air. Thus, the cuff can be properly constricted with a regular shape matching the contact surface.

The auxiliary device may be composed of one male and female mold member, but it is more effective to use both male and female mold members.

[0007]

FIG. 2 shows an example of the auxiliary device of the present invention. The device includes a female member 6 having a substantially oval-shaped concave abutting surface 6a conforming to the front shape of the cuff 3 in a state where the cuff 3 is curved so as to warp to the back surface of the mask body 2, and the back surface of the cuff 3 A male member 7 having a substantially oval-shaped convex contact surface 7a conforming to the shape, and the female member 6 is provided with a ball joint 6b at the center of the distal end, while the male member 7 is provided on the upper surface. An arm-shaped arm member 7b is integrally formed, and the tip of the arm member 7b is connected to the ball joint 6b so that the male member 7 can be pivoted and pivoted at the tip of the female member 6. Supported.

The female member 6 has a concave portion 6c formed at the rear end of the peripheral portion of the concave contact surface 6a so as to coincide with the air tube connecting portion 5a. The connection portion 5a is prevented from contacting and bending with the female mold member 6, so that air can be removed smoothly. The male member 7 is provided with a breathing tube connecting portion 4 at the rear end of the convex contact surface 7a.
The escape groove 7c is formed so that the convex contact portion 7a does not interfere with the respiratory tube connection portion 4a when the male member 7 is pressed against the cuff 3.

Next, a method of using the auxiliary device will be described. First, the laryngeal mask 1 is set such that the front surface of the cuff 3 faces the concave contact surface 6a of the female die 6 as shown in FIG. Next, as described above, the male member pivotally supported on the distal end of the female member 6.
By rotating the member 7 and pressing the convex contact portion 7a against the back surface of the cuff 3 by a syringe (not shown) connected to the air tube 5, the convex contact surface 7a becomes concave as shown in FIG. Interfacing 6
The air in the cuff 3 is evacuated until the value matches a. At this time, the convex contact surface 7a sequentially contacts the front end to the rear end of the cuff 3 and pushes out the air in the cuff 3 from the farthest portion of the air tube connecting portion 5a toward the connecting portion 5a. The air is evenly evacuated and contracts along the contact surfaces 6a and 7a. As a result, the cuff 3 can be constricted to a correct state with no kinks or wrinkles in a regular shape that matches the contact surfaces 6a and 7a. Note that by using an auxiliary device corresponding to the laryngeal mask 1 having a different size and configured in the same manner as the above-mentioned auxiliary device, the other laryngeal mask 1 can be similarly squeezed.

In this embodiment, a pair of male and female members 6, 7
Are provided so as to be freely movable toward and away from each other, but a female member 6 having a plurality of concave contact surfaces 6a having different sizes, and a convex contact surface 7a corresponding to the plurality of concave contact surfaces 6a are provided. It is also possible to constitute an auxiliary device with a plurality of male members 7 provided with the above, and to provide the male and female members 6, 7 without being connected.

In this embodiment, the cuff 3 is evacuated using the male and female mold members 6, 7, but the contact surface of one of the male and female mold members 6, 7 is cuffed. The air inside the cuff 3 may be evacuated while being pressed against the cuff 3.

The laryngeal mask 1 is subjected to autoclave disinfection and regeneration. Therefore, if the material of the auxiliary device can withstand a temperature of about 150 ° C., after the shape of the laryngeal mask 1 is adjusted, it can be sterilized together with the auxiliary device. In addition, before inserting the laryngeal mask 1, cuff 3
It is also useful in emergency situations where time is required to keep the shape clean and save time.

[0013]

As is clear from the above description, according to the present invention, the cuff of the laryngeal mask can be constricted to a correct state without kinks or wrinkles in a regular shape. It will be easier.
