Technical Field

The invention belongs to the technical field of A61F6/08 pessaries, and particularly relates to an adjustable pessary.

Background

A pessary is a medical appliance used for treating female uterine prolapse and is generally made of polyethylene and silicon rubber materials. The common pessary on the market can not be adjusted in size, for example, the circular pessary is generally provided with five outer diameter specifications of 51 MM, 57 MM, 64 MM, 70 MM and 76 MM. Before the test bed is used, a patient needs to be tested to be suitable for which specification, and the unsuitable pessary can only be discarded during the test, so that unnecessary waste is caused.

Chinese patent document CN 104622620a discloses an adjustable pessary, which comprises an umbrella-shaped support made of elastic material, wherein the umbrella-shaped support is similar to an inverted umbrella, and can be retracted before being pushed into vagina, so as to be conveniently pushed into vagina. After the pessary reaches a preset position, the movable sheet push rod pushes the movable sheet to move so as to realize the transverse expansion of the pessary body, thereby fixing the pessary at the uterine orifice. The disadvantages of the scheme are that: because the space in the vagina is narrow, the two moving modes of the movable sheet push rod provided by the scheme both need to rotate the movable sheet push rod, and the moving mode is not easy to implement in the vagina.

The main inventor of the present application, namely the main inventor of the above patent scheme, has formed the present application in the process of solving the above practical difficulties.
