- the compartment 20 defines a cavity 21.
- the cavity 21 extends inside the central body 1.
- the central body 1 is not full: its interior is hollowed out facing the compartment 20.
- the compartment 20 and the cavity 21 can be lined with a membrane or a film of any material or contain a container, and form a cubicle 6.
- the hollow cubicle 6 is cylindrical in shape and its height is between 0.2 cm and 1 cm.
- the cavity 21 of the compartment 20 and / or of the central body 1, or the cubicle 6, contains all or part of the allergen composition to be inoculated into the patient.
- the compartment 20, or where appropriate the cubicle 6, has or carries at its lower end 7 a multi-point needle 8, which is intended to perforate the skin when pressure is exerted by the doctor on the pressure member 3 and to allow penetration of the allergen composition.
- FIG. 5 represents a multi-point needle 8 which comprises at least one crown 12 on which the points 13 are positioned or fixed.
- the needle 8 has several concentric crowns 12, in order to increase the number of points while maintaining a restricted diameter for the needle, and in order to improve the penetration of the allergenic composition into the skin of the patient.
- the multi-point needle 8 contains eight points 13 also distributed, said 8 points 13 being distributed over one or two crowns.
- the multipoint needle 8 has two concentric rings of diameter from 1.5 to 3.5 mm, each crown having 4 points 13 of length from 1 to 3 mm, angularly positioned alternately.
- the central body is integral over its entire circumference with a bending crown 16.
- This crown has the same external shape as the central body, so as to be fixed over its entire circumference or its perimeter to the external periphery of the central body 1.
- the ring bending 16 allows a controlled vertical translation of the central body 1 when vertical pressure is applied to the pressing member 3.
- the ring bending 16 is made of materials allowing it to be flexible and resilient, in order to accompany and limit the descent of the central body 1 during a pressure exerted on the pressure and gripping member 3.
- This bending ring 16 must have a width sufficient to fully accompany the descent of the central body 1 when the member 3 is pressed.
- the allergen composition to be inoculated is not only found in compartment 20 or cavity 21 or cubicle 6 but also in space 14.
- the outer end of the crown 16 is integral over its entire circumference or perimeter with a rigid support 17.
- the purpose of this rigid support 17 is to position and maintain the kit on the patient's arm. Its inner periphery is therefore of the same shape as the shape of the outer periphery of the crown 16.
- the anchoring point of the outer end of the crown 16 on the rigid support 17 is solidly dimensioned, so as to that the crown 16 can withstand the pressure applied via the pressure and gripping member 3 without detaching from the rigid support 17.
- the skin kit according to the invention comprises a blister 15 fixed on the underside of the support 17 and covering the the entire bottom surface of the kit. This blister 15 makes it possible to close the spaces 14, and the compartments 20 or the cubicles 6, containing the allergen composition (s). This blister is removable to allow the test to be carried out.
- the cutaneous diagnostic kit for atopy can comprise three central bodies 1.
- Each of the central bodies 1 can contain in its cavity 21 its compartment 20 and / or its central body 1 , or in its cubicle 6, as well as in its space 14, an allergen composition to be inoculated.
- This allergen composition can be different from one central body to another, on the same kit.
- the kit according to the invention can carry as many different allergenic compositions as there are central bodies. In this way, in a single application of the device according to the invention, the doctor will be able to determine different allergies in a patient.
- the central bodies are separated from each other, on the same kit, by variable distances.
- the distance 9 separating the first and the second central body is different from the distance 10 separating the second and the third central body, each of said distances 9 and 10 being different of the distance 11 separating the first and the third central body.
- the difference in value between the distances separating the different central bodies may allow easier identification when reading the test of the allergen compositions applied by each central body.
- the distance 9 is between 1 cm and 3 cm
- the distance 10 is between 2 cm and 4 cm
- the distance 11 is between 3 cm and 7 cm. In this way, the distances 9, 10 and 11 are large enough to avoid overlaps between the reactions of the different central bodies, as well as errors in the interpretation of the reactions caused between the allergenic composition and the skin.
- the skin kit according to the invention can be produced from a single molded piece.
- the skin kit according to the invention comprises at least one allergen composition, located in the cavity 21 of the compartment 20 and / or of the central body 1, or in the cubicle 6, as well as in the space 14 existing between the blister 15 and the lower faces 18 and 19 of the bending ring 16 and of the central body 1.
- the pressure which is exerted on the pressure and gripping member 3 has two consequences: on the one hand, the multi-point needle 8 will penetrate in the patient's skin, allowing an intradermal presentation of the allergen composition.
- the allergen composition also being in the space (14), the pressure on the pressure member 3 will allow an epidermal presentation of the allergen composition, this presentation on the patient's skin taking place within the limits of the circle defined by the edge 5 in contact with the patient's skin.
- the allergen composition contained in the central body is preferably in the form of a gel, which prevents it from flowing out of the space (14) when the blister
- the allergen composition (s) contained in the kit of the invention each comprise a mixture of allergens, each mixture being composed of allergens belonging to a specific class of allergens responsible for the most frequent allergies.
- the mixture consists of the different allergens of its class in equal proportions.
- the volume of a mixture is therefore 0.5 ⁇ l to 2 ⁇ l, and the concentration of allergens is 100 to 300 IR / ml with a preference of 300 IR when this is technically possible.
- a mixture corresponding to a central body consists of allergens of the pollen class, which may contain grass, herbaceous and tree pollen.
- This mixture of pollen allergens may contain a high peptide concentration of PR10 proteins, pectase lyase and profilins, natural or synthetic. These proteins are the major major proteins of the pollen class.
- the allergen composition may moreover comprise a mixture of food allergens, which may contain a high peptide concentration of chitinases, of Lipid Transfer Proteins, natural or synthetic.
- the allergen composition may comprise a mixture of domestic environmental allergens, which may be composed of allergens of mites, dander of dogs and cats, as well as molds. This mixture of domestic environmental allergens can include a high peptide concentration of tropomyosins, profilins and cystine proteases, natural or synthetic.
- the mixture of allergens comprises, in equal proportion, the various allergens or their major major proteins of each of the three classes already mentioned: class of pollens, class of allergens food, class of allergens of the domestic environment.
