Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-5, the present invention provides the following technical solutions: disposable cervical dilatation mould, including cervical expansion rod 1, the one end integrated into one piece of cervical expansion rod 1 has handle piece 4, and cervical expansion rod 1 is equipped with water injection hole 6 with the inside of handle piece 4, and the bottom surface of handle piece 4 is run through to the one end of water injection hole 6, and water injection hole 6 is convenient for medical personnel to use the syringe to the inside water injection of cervical expansion rod 1.

Cervical expansion rod 1 is different from one end integrated into one piece stopper rod 3 of handle piece 4, cervical expansion rod 1 has seted up interior groove 2 that contracts near the one end outside surface of stopper rod 3, the bottom surface of handle piece 4 is located the outside of water injection hole 6 and has seted up and has moved back position groove 7, the inner wall that moves back position groove 7 is fixed with rubber ring 8 through glue bonding, there is shutoff ring 9 in rubber ring 8's inboard through the integrated into one piece that moulds plastics, in this embodiment, move back position groove 7 and be convenient for rubber ring 8 to place inside it, rubber ring 8 is used for fixed shutoff ring 9.
