Device for the self-collection of cells from the cervix, relating to a device designed for allowing women themselves to carry out the collection of cells from the cervix, with the aim of being able to diagnose women with precancerous lesions or cancer, who, for different reasons, lack the possibility of going to the gynecologist or refuse a pelvic examination. To this end, the device is marketed packaged in a package where it is already prepared and sterilized to be used directly without any previous operation, beyond the removal of a cap for covering and protecting the area which is introduced into the vagina and where the sample is collected and which, once collected, serves for protecting said area once again.
