Method for the disinfection and the quality control of the disinfection of the hands of a user and apparatus for carrying out the method

Method apparatus and computer program for the disinfection and the quality control of the disinfection of the hands of a user, wherein the method comprises the following steps: dispensing a predetermined amount of the mixture of a disinfectant substance and a light reflection modifying substance on the hands to be disinfected; allowing the user to smear and rub the mixture on his/her hands; inserting the hands one after the other into an imaging compartment (11) of an apparatus (10) for disinfection quality control; illuminating the inserted hand with light sources (14) emitting light having a predetermined spectral distribution and intensity; recording the image of the hand (9) from both sides by cameras (16); processing the recorded image to provide distinction between areas of the hand contacted and non-contacted by the mixture, wherein the light reflection modifying substance is a substance that absorbs light in at least a predetermined wavelength range which is added to the disinfectant substance in an amount that decreases light absorption of areas treated by the mixture and retains at the same time disinfectant properties; the light source emits light to cover the predetermined range and the cameras have sensitivity in that range; furthermore, in the processing step areas of the hand (9) are made brighter which were not contacted previously by the mixture.

Non-invasive method to assess embryo competence

Non-invasive method to assess embryo competence

The efficiency of embryo implantation is surprisingly low in humans. This can either be attributed to the high rate of chromosomally abnormal embryos, or to uterine factors, if the embryo is chromosomally normal.

Multilayer device for treating wound dehiscence

Multilayer device for treating wound dehiscence

Multilayer structures with an adhesive layer are most often used for open wounds, seams and abrasions. The invention relates to a multilayer structure promoting wound healing for the treatment of Dehistence along the sutures, wherein the layers of the structure comprise an adhesive layer providing adhesion, characterized in that the structure comprises a carrier layer (1), an intermediate adhesive layer (2), a protective layer ( 3), a packaging, cover layer (4), wherein the carrier layer (1) and the intermediate adhesive layer (2) comprise a material-deficient part (5) enabling the treatment of the wound, the order of the layers being: packaging, cover layer (4). ), a carrier layer (1), an intermediate adhesive layer (2), a protective layer (3), and finally a packaging, cover layer (4).
