Description

92792

The present invention relates to a method for producing a protective garment for hygienic conditions, such as a surgical garment, which protective garment is formed of a nonwoven fabric or the like as a disposable jacket. The invention also relates to a protective garment 10 produced by the method.

A wide variety of protective clothing for surgical and other treatments is known, the function of which is to prevent the transfer of microbes from the medical staff to the patient or vice versa. Surgical gowns 15 are often disposable and sterilized. In known protective garments, the garment is usually formed of several parts which are sewn together just like a normal garment. Since protective clothing is generally required to have the best possible protective effect and, on the other hand, easy handling in clothing, the protective clothing generally consists of an intact surface at the front, the so-called omlott principle for a closable jacket.

The disadvantage of sewn seams is their leakage in objects requiring absolute cleanliness, whereby it is possible that the clothing under the protective clothing of the wearer of the jacket becomes contaminated, e.g. through the blood or other liquids of the patient to be cut, when they wet the seam. In addition, the known protective garments have a large number of seams, because the garments are made of several parts to be sewn together.

Various other sealing methods for protective clothing are also known, including ultrasonic welding, adhesive tapes and various soy. However, there is no protective garment on the market in which the number of seams, taking into account the risk of contamination, is minimized in the design of the garment. The object of the present invention is to provide such a protective garment 92792, which is mainly characterized in that - the protective garment is cut in one piece into a blank comprising substantially sleeves and an upper part covering the upper body and a lower part covering the lower body and a taper between them, - glue or sealant is applied to the blank at the seams of the sleeves and the upper part, - the blank is folded by turning the upper part twice so that the front of the garment remains substantially seamless, and - the sleeves and the back-forming parts of the protective garment are glued or heat-sealed together.

Above all, the protective garment according to the invention is airtight and protects practically the entire body of the wearer, which is a considerable improvement from the point of view of hygiene. In addition, the manufacturing method according to the invention is inexpensive, which in turn is a basic condition for the economy of a disposable product.

Preferred embodiments of the method according to the invention and the protective clothing according to the invention are characterized by what is stated in the claims below.

The invention will now be described in more detail, by way of example, with reference to the accompanying drawing, in which Figure 1 shows a blank of a protective garment according to the invention, Figure 2 shows a protective garment according to the invention pre-seamed.

The protective garment blank 1 according to Fig. 1 is cut from a nonwoven fabric in one piece. For the sake of clarity, the left side of the blank is shown pre-folded and seamed as a protective garment according to the invention. It is found that when the blank is folded top part Ib e.g. as indicated by arrow 35-fold, and the sleeve is obtained that the back is • 92 792 3 therefrom and seamed substantially by a single operation. The blank separates the symmetrical parts of the upper body and the lower body 1b, respectively, and the opening 5 cut for the neck, separated by the reductions 1a at the armpits. folded e.g. according to Figure 1 and glued or heat sealed. The result is, according to Fig. 2, a protective garment 7 showing a substantially seamless seamless surface at the front. 10 With further reference to Fig. 1, the so-called the omlott strips are formed on the one hand by gluing or heat-sealing the strips 5a and 5b attached to the fabric and on the other hand from the strips 6a and 6b formed by cutting the strips from the side edges le of the lower body part of the blank.

The protective garment according to the invention according to Figure 2 does not have seams on its front, as shown above. At the front, only the strap 5b fastened at the waist height by gluing or heat-sealing 11a, which is tied together with the strap 6a when carrying the garment, is visible. Respectively, the straps 5a and 6b are tied together around the waist of the wearer. The collar of the garment can be closed: 25 eg with Velcro 8, which is also glued to the product.

It will be apparent to those skilled in the art that the various embodiments of the invention are not limited to the example set forth above, but may vary within the scope of the following claims.
