Germ-free surgical laundry.

The surgical linen used in clinics and hospitals is generally cleaned immediately before use sterilized, i.e. made sterile, which is a loss of precious time, especially if every lost Minute can have serious implications for the patient's life.

To avoid these disadvantages, it has already been proposed to keep the sterile surgical clothes in carefully airtight plastic packaging. However, there is no guarantee that the surgical clothes will still be free of germs when they are removed from the packaging is, because the smallest crack in the packaging or even a pinprick is enough to question the sterility, which in turn is an irresponsible risk as it can have deadly poles.

According to the invention, therefore, surgical underwear that has been made sterile in a carefully sealed airtight plastic packaging be created, the purity of which in the At the moment of use it can be determined perfectly and instantly at a glance or, if necessary, with a handle.

The surgical underwear proposed according to the invention is thereby characterized in that they are in an airtight and permeable for the sterilizing agent used, evacuated plastic packaging is folded up so that it has the strength of wood. Therefore, if the If the packaging only has a tiny hole such as a needle prick, the surgical clothing absorbs it by penetrating it the air in a few moments its normal softness, so that due to the stiffness of the surgical clothes lets you determine immediately whether it is still free of germs.

In the drawing, an embodiment of the invention is shown, namely shows:

Fig. 1 is a plan view, and

FIG. 2 shows a section along the line II-II in FIG. 1.

The surgical underwear 1 shown in the drawing is folded inside a packaging made of a plastic film which surrounds it on one longitudinal side 2. The free longitudinal edges 3, as well as the two free transverse edges 4 and 5 of the packaging are after the formation of the air void

in the package formed in this way airtight with each other welded.

A plastic is used for the packaging that is airtight but permeable to the sterilizing agent. that is used for the surgical clothing in the packaging. This agent can be made from steam, gas or Radiation exist. Substances that have this dual property have are known, so that an appropriate material can be selected.

Before the packaging is hermetically sealed and sterilized together with the surgical clothing it contains, an indicator strip is inserted that changes color during sterilization. In this case, a section 6 is arranged on one upper side of the folded surgical underwear, an adjoining section 7 in the middle of the underwear and a further section 8 on the other side of the underwear. Due to the color of the indicator strip, the sterility of the laundry can be determined, and the section 7 located in the middle of the laundry shows whether the sterilization has taken place not only on the surface but also into the interior of the laundry .

Due to the rigidity of the surgical underwear, it can be determined immediately that the sterility is still given, and if the indicator strip is also continuously discolored,
