JPH04138175A - Pressure respiratory jacket for aircraft pilot - Google Patents

Abstract

PURPOSE:To effectively give a resisting pressure to the breast at the time of pressure respiration by disposing bladders mounted on a jacket body for aircraft pilot in the position pressing the breast side and back side of a pilot by expansion. CONSTITUTION:A jacket body 2 is provided with a bladder 3 on the breast side of a pilot and a bladder 4 on the back side, and the bladders 3, 4 are expanded by supplying a high pressure air through a horse 10 and a connecting pipe 9. The pilot wearing the jacket is pressed in the breast side and back side by the expanded bladders 3, 4, and receives a resisting pressure on the breast part at the time of pressure respiration, whereby the damage of the lungs is prevented, and the respiratory motion is assisted.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a jacket worn by an aircraft pilot when performing pressurized breathing.

(Prior Art) In recent years, as aircraft become more sophisticated, there are many cases in which passengers lose consciousness due to being exposed to large accelerations (G), leading to accidents.

As a result of research aimed at preventing such accidents, it has been recognized that increasing the breathing air pressure higher than the ambient pressure in accordance with acceleration is an effective measure to improve the acceleration resistance of passengers.

(Problems to be Solved by the Invention) However, if pressurized breathing air is supplied to the pilot, there is a risk that the pilot's lungs may be damaged, and there are also problems in that exhalation becomes difficult.

In order to solve this problem, it has been proposed to apply counter pressure to the pilot's chest, but at present no specific means for applying counter pressure has been provided.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a jacket that can effectively apply counterpressure to a pilot's chest when performing pressurized breathing.

(Means for Solving the Problems) The present invention is characterized by comprising a jacket main body worn by an aircraft pilot and a bladder attached to the jacket main body, and when the bladder expands, and the dorsal side.

(Function) According to the configuration of the present invention, when the bladder is inflated, the torso and dorsal sides of the aircraft pilot wearing the jacket body are pressed, and counterpressure during pressurized breathing is applied to the pilot's chest. can do.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

An aircraft pilot's pressurized breathing jacket 1 shown in FIGS. 1 to 3 includes a jacket body 2 and a pair of bladders 3 and 4 built into the jacket body 2 and attached thereto.

The jacket body 2 covers the pilot's torso, and has openings around the neck, arms, and torso of 5, 6°, and 7°.
The front side can be opened and closed with a zipper 8 for convenience when putting on and taking off.

One bladder 3 is built in the jacket body 2 on the pilot body side, and the other bladder 4 is built in the pilot back side. The bladders 3 and 4 are arranged at positions where, when expanded, they press the torso and dorsal sides of the pilot.

Furthermore, one bladder 3 and the other bladder 4 are communicated via a connecting pipe 9. The connecting pipe 9 is installed on the top shoulder side of the jacket body 2.

A flexible hose IO for supplying high-pressure gas is connected to the lower part of the bladder 3 on the pilot body side.

The hose 10 is connected to a high-pressure air source (not shown), and the bladders 3 and 4 are inflated by supplying high-pressure air therefrom. As a source of high pressure air, for example, bleed air from an aircraft engine is used.

The pilot wearing the above jacket is pressed by the expanded bladders 3 and 4 on his torso and dorsal sides.
During pressurized breathing, the chest receives counterpressure, which prevents damage to the lungs and assists in exhalation.

In addition, by placing the connecting pipe 9 on the pilot's shoulder of the jacket body 2, the movement of the pilot is not obstructed, and high-pressure air is supplied to the bladders 3 and 4 from a single point on the torso side. This makes it possible to effectively apply counterpressure to the pilot's chest for pressurized breathing with a simple structure.

Note that the present invention is not limited to the above embodiments,
It may be a bladder attached to the jacket body or one that presses against the pilot's torso and back sides.

(Effects of the Invention) According to the pressurized breathing jacket according to the present invention, the torso and dorsal sides of an aircraft pilot who performs pressurized breathing are pressed by the bladder, and counter pressure against pressurized breathing is applied to the pilot. It can prevent lung damage and assist in exhalation.
