## Abstract

A decontamination device for medical material, including a support intended to receive and hold said medical material to be decontaminated on a predefined axis, a spraying means, a drying means and an irradiating means, wherein said spraying means is mounted in rotation about said predefined axis and in translation parallel to said predefined axis, in such a way that the spraying is directed towards said predefined axis, said drying means is mounted in translation parallel to said predefined axis, and said irradiating means is mounted in translation parallel to said predefined axis.

## Claims

### Claim 1

A decontamination device for medical material comprising:
a support intended to receive and hold said medical material to be decontaminated, a spraying mechanism, a drying mechanism and an irradiating mechanism, said drying mechanism and said irradiating mechanism further comprise a part forming a cylindrical passage, configured to receive said medical material to be decontaminated, wherein said spraying mechanism is configured to rotate about the longitudinal axis of symmetry of said cylindrical passage and in translation parallel to said axis of symmetry, in such a way that the spraying is directed towards said axis of symmetry, said drying mechanism produces an air knife and is mounted in translation parallel to said axis of symmetry, and said irradiating mechanism is mounted in translation parallel to said axis of symmetry, wherein the air knife passes through a trajectory forming an angle between 10° and 85° of said axis of symmetry.

### Claim 2 (depends on 1)

The decontamination device for medical material according to claim 1, comprising:
a support intended to receive and hold said medical material to be decontaminated, a spraying mechanism, a drying mechanism and an irradiating mechanism, said drying mechanism and said irradiating mechanism are included in a part forming a cylindrical passage, intended to receive said medical material to be decontaminated, characterised in that said support is mounted in rotation about the longitudinal axis of symmetry of said cylindrical passage and in translation on said axis of symmetry.

### Claim 3 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said irradiating mechanism forms a cylinder arranged on the inner surface of said annular part.

### Claim 4 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said drying mechanism is mounted in rotation about the axis of symmetry.

### Claim 5 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said irradiating mechanism is also mounted in rotation about the axis of symmetry.

### Claim 6 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said drying mechanism capable of producing an air knife is arranged annularly about the axis of symmetry.

### Claim 7 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said air knife is substantially perpendicular to the axis of symmetry.

### Claim 8 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said irradiating mechanism is a source of UV and preferentially of UV-C.

### Claim 9 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said irradiating mechanism is a source capable of emitting sequentially or simultaneously radiation belonging to the UV-A, UV-B and UV-C range.

### Claim 10 (depends on 1)

The decontamination device for medical material according to claim 1, wherein said spraying mechanism is a nebulisation means.
