Abstract:
1. Vaginal speculum comprising: two spoon blades which form a spoon blade assembly configured to be introduced into a vagina, said spoon blades being elongated and position substantially alongside and opposite each other, wherein the one spoon blade at one end of the spoon blade assembly comprises two bodies to form a housing of essentially U-shaped cross-section and the other spoon blade is hingeable with respect to the one spoon blade around a hinge axis, wherein the speculum has a closed state when the spoon blades are in a position in which they have been brought together and a opened state when the blades are spread at an internal end of the speculum, wherein the exterior of the U-shaped housing is shaped for accommodating said housing in the mouth of the vagina after the spoon blades have been introduced into the vagina, wherein the housing is provided with at least one surface that tapers in the closed state and the opened state, with respect to the longitudinal direction of the speculum in the direction of the external part thereof; said tapering surface for holding said housing in place, in both the closed state and opened state, in the vagina by the musculus sphincter ani externus and/or the musculus bulbocavernosus is able to act/engage when the speculum is in the position in which it has been inserted in the vagina and is ready for use, such that a compressive force pushing the speculum into the vagina is exerted on said tapering surface, wherein said hinge axis is arranged such that, when the speculum is inserted into the vagina, said hinge axis lies inside the mouth of the vagina, and wherein the at least one tapering surface forms part of an indentation made in the housing.
