JPH11178926A - Gas supplier for breathing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To secure an easy posture for moving by equipping a handle and casters to make moving easier and making the length of the handle freely adjustable in a gas supplier for breathing used mainly for the home oxygen therapy of a respiratory disease patient. SOLUTION: A handle 1 and casters 5 are equipped on the main body of this gas supplier for breathing. When the length of the handle 1 is to be changed, a screw 2 is loosened to take up/down the handle 1 to an arbitrary position and then the screw is fastened to fix the handle 1. A storing type chair 3 is attached to the handle 1 or the main body and casters 5 to the main body via springs 7. When a weight is loaded on the main body, springs 7 are contracted and stoppers 4 equipped under the main body are grounded on the caster grounding plane to float casters. When the storing type chair 3 is to be used, a double folding seat face fixed by hooks is drawn forward to be flat so that the seat face is supported by the upper part of the main body and several supporting points, and then used as a chair.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a respiratory gas supply device mainly used for home oxygen therapy for patients with respiratory diseases, and the length of a handle can be arbitrarily changed according to the height of the user. The present invention relates to a respiratory gas supply device that can be moved in a posture with a small load and that can be rested by an attached chair at any place.

[0002]

2. Description of the Related Art Oxygen therapy for providing oxygen-enriched gas to patients with respiratory diseases, especially oxygen therapy at home,
In recent years, wealth has become more important and popular. In these oxygen therapies, portable respiratory gas supply devices that can be used not only indoors but also outdoors have recently been used.

[0003] The portable respiratory gas supply apparatus has only a moving fixed handle and a moving caster as an attached function. Therefore, when the patient moves with the portable respiratory gas supply device, it is necessary to take a posture that matches the fixed handle. It was hanging. In addition, the burden on the body increased the degree of fatigue, and even if you wanted to sit down for a break, there were not many benches installed on your daily life road, and you could not rest.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems. By changing the length of the handle, the moving posture can be made easier. To realize a respiratory gas supply device that can take a break at the same place.

[0005]

According to the present invention, there is provided a breathing gas supply apparatus comprising a handle and a caster for facilitating movement, the length of the handle being arbitrarily changed, and a retractable chair. The caster is attached to the handle or the main body via a spring, and when the weight is applied to the main body, the spring contracts, and the stopper provided at the lower part of the main body contacts the caster grounding surface. , A caster for disabling a gas supply for respiration.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an external view of the entire apparatus. FIG. 2 shows details of the handle. FIG. 3 shows the details of the retractable chair. FIG. 4 shows details of the stopper portion. FIG. 2 shows a method of adjusting the handle (1). This adjustment method has the simplest structure, in which the screw (2) is loosened, the handle (1) is moved up and down, the screw (2) is tightened at an arbitrary position, and the handle (1) is fixed.
In a complicated structure, there is a method in which a grip switch is provided in the handle grip portion, and the hook fixing the handle is released by gripping the switch to adjust the position of the handle.

[0007] When the retractable chair (3) is used, FIG.
As described above, the folded seat surface fixed with a hook or magnet or the like is flattened toward the front, and the seat surface is supported by the upper part of the main body and several fulcrums, so that it can be used as a chair. As shown in FIG. 4, the operation mechanism of the stopper (4) connects the respiratory gas supply device and the caster (5) with the support (6) and inserts the spring (7) between them. Spring when added (7)
Are compressed, and the stopper (4) projects and works.

[0008]

By using the respiratory gas supply device of the present invention, the handle can be adjusted according to the operator's comfortable posture, and the retractable chair allows the user to sit at any place.
It is suitable as a portable respiratory gas supply device.
