Abstract
Skin test device has a film backing. The film backing is made of silicone, and is marked off into divisions by grooves. The divisions each have a different sample containing a suspected allergen. The film backing has a see-through feature and the condition of the skin can visually be checked when the film backing is staying on the skin. The divisions are easily separable from each other. When certain samples cause significant allergic reactions, the divisions corresponding to those samples can be removed immediately.
Claims20
A skin test device comprising:
- a film backing;
- and
- a sample that is placed on one surface of said film backing, the sample containing a suspected allergen, wherein
- said film backing is transparent of said film backing at least at the portion where said sample is placed, and
- said film backing is marked off into divisions, the divisions each having a different sample placed thereon, wherein
- the divisions of said film backing are easily separable from each other.

A skin test device comprising:
- a film backing;
- and
- a sample that is placed on one surface of said film backing, the sample containing a suspected allergen, wherein
- said film backing is see-through from only one side to the other of said film backing at least at the portion where said sample is placed, and
- wherein said film backing is marked off into divisions, the divisions each having a different sample placed thereon, wherein
- the divisions of said film backing are easily separable from each other.
3 more elements
A skin test device comprising:
- a film backing;
- and
- an adhesive layer provided at a predetermined position on one surface of said film backing to secure said film backing to the skin of a subject, at least two hollow spaces being provided in said film backing at a predetermined position, a hollow space of the at least two hollow spaces having such a size that is required to place a sample containing suspected allergen on the skin while keeping said film backing affixed to the skin, wherein
- said film backing is see-through at least along the periphery of the hollow space, and
- a see-through cover film that is adapted to be placed over the other surface of said film backing so that the hollow space is covered with said cover film while said film backing is secured to the skin, said cover film being for preventing the sample placed on the skin from running out of the hollow space, wherein said film backing has at least two hollow spaces formed therein and said cover film extends over all hollow spaces, said cover film being marked off into two or more cover sections that correspond to the respective hollow spaces so that the cover sections are easily separable from each other.

A skin test device comprising:
- a film backing;
- an adhesive layer provided at a predetermined position on one surface of said film backing to secure said film backing to the skin of a subject, at least two hollow spaces being provided in said film backing at a predetermined location, a hollow space of the at least two hollow spaces having such a size that is required to place a sample containing suspected allergen on the skin while keeping said film backing stay on the skin, wherein
- said film backing is see-through from only one side to the other at least along the periphery of the hollow space, a see-through cover film that is adapted to be placed over the other surface of said film backing so that the hollow space is covered with said cover film while said film backing is secured to the skin, said cover film being for preventing the sample placed on the skin from running out of the hollow space, wherein said film backing has at least two hollow spaces formed therein and said cover film extends over all hollow spaces, said cover film being marked off into two or more cover sections that correspond to the respective hollow spaces so that the cover sections are easily separable from each other.
A skin test device comprising:
- a film backing;
- an adhesive layer provided at a predetermined position on one surface of said film backing to secure said film backing to the skin of a subject;
- and
- at least one keeper region that is provided on one surface of said film backing, said keeper region being for keeping a sample that contains a suspected allergen, wherein
- said film backing is see-through from either side at least at the portion corresponding to said keeper region, and
- wherein said film backing is marked off into divisions, the divisions each having a different keeper, wherein
- the divisions of said film backing are easily separable from each other.
