APPARATUS FOR PRODUCING ARTIFICIAL BREATHING OR RESPIRATION Filed Nov. 12, 1955 J Nor'cji TL Patented Dec. 29, 1936 APPARATUS FOR; PRODUCING ARTIFICIAL BREATHING R RESPIRATION Josef August Nordin, Stockholm, de ns or to Aktiebolage't Stille-Werner, Stockholm, Sweden, a corporation of Sweden Application November 12, 1935, Serial No. 49,406 In Sweden November 21, 1934 6 Claims. (o1. ms-3e) The present invention relates to such'apparatus for producing artificial breathing or respiration,

which consists of a shield-like hood or casing intended to be placed over the breast and belly of a patient, so that an intermediate space is formed between the body and the hood, in which space the air pressure can be reduced or raised.

Such breathing hoods should preferably be easy is liable to cause an lnjurious cooling action on the patient being attended. Moreover, considering that the respiratory movements of the body should not be checked as regards certain portions of the body and that, accordingly, too firm a bearing pressure and too straight a fit will generally be undesirable, it is obvious that the provision I of a reliable and simple tightening device is of very great importance.

Accordingtothe present invention this is accomplished owing to the fact that in combination with the hood proper a flexible, soft pad is employed, on which the relatively rigid shanks of the'hood bear on both sides of the patient, round whom the hood and the pad are clasped together by means of one or several belts, straps or the like, so that the shanksof the hood sink down into the pad and the rims of the latter will conveniently be bent up towards the shanks of the hood, and that to the end portions of the hood are fastened relatively thick, flexible tightening strips or the like adapted to fit tightly against the body of the patient, f. i. by means of belts or straps, the pad being, moreover, arranged for joining on to said tightening strips.

An embodiment of the invention is illustrated on the accompanying drawing, in which Figure 1 is a side view of the breathing apparatus in question applied to the patient to be attended, and

Figure 2 is a tranverse section through the apparatus.

The hood I, made of a suitable material, is relatively rigid and may have approximately the shape shown by the drawing, and it should be so dimensioned that there exists a relatively large space between the hood, on the one hand, and the breast and belly of the patient as well as the lateral portions of the thorax, on the other hand (see Figure 2). The shanks of the hood bear on a fiexible, soft pad 2 under which is arranged a relatively wide belt 3, the ends of which are secured to supporting or carrying members 4, which, by means of the belt 3 support the pad 2. To'the carrying members 4 are secured belt portions 5 which can be strapped together by means of a belt 6 provided over the hood, the rims of the pad being, in this way, bent upwardly against the shanks of the hood, while at the same time the edges of the shank are depressed to some extent into the soft pad, with the result that a completely reliable tight fit is accomplished between the pad and the shanks of the hood.

For the purpose of effecting a tight fit between the end portions of the hood and the body of the patient, relatively thick, flexible tightening strips suitably consisting of rubber are fastened to said end portions. Secured to the strips 1 are loops 8, or the like, which form guides for belts 9 or the like extending approximately parallel to the outer edges of the strips at a distance therefrom. These belts are passed through rings Ill secured to relatively wide belts l I provided under I the pad 2.

to projections [2 on the hood and are adapted to depress the strips into close engagement with the which may be coupled a flexible tube leading to a device (not shown) producing fluctuations of pressure in the hood.

The application and the removal of the hood will evidently cause no difficulties whatever, but can be effected by some simple manipulations which may need no detailed explanation. Within certain limits one and the same hood may be employed for patients of different size, which, of;

course, involves an essential advantage.

The supporting or carrying members flare sub- The ends of the belts 3 are fastened v stantially intended to be used in case'thepad and the patient are placed on a yielding support, for instance, on a litter or a bed. If the support is more steady the carrying members may be omitted, in which case the belt 3 and the belt portions 5 are made in one piece. It is not absolutely necessary to have the belts 9 guided on the strips 1 in the manner shown in the drawing.
