Abstract

The invention provides a disposable cervical dilator attached with a medicine film, and a preparation method of the disposable cervical dilator with the medicine film. The cervical dilator is attached with the medicine film of local anesthetics; when the disposable cervical dilator is used, the medicine film is swollen and dissolved under body temperature; and medicines in the medicine film are released out, and are absorbed by a cervical mucous membrane, so that pain of patients is relieved, and occurrences of adverse reactions are reduced. The disposable cervical dilator with the medicine film is convenient to use, and simple and feasible in preparation process; the related pharmaceutic adjuvants are all easy to purchase and are low in cost; and the disposable cervical dilator has good social and economic benefits.

Description

technical field [0001] The invention relates to a medical device for dilating the cervix that is commonly used clinically in obstetrics and gynecology, in particular to a disposable cervical dilator with a drug film.

At present, cervical dilators are widely used in obstetrics and gynecology clinical operations, such as artificial abortion, hysteroscopy, placement and removal of intrauterine devices, and diagnostic curettage. [0003] There are many types of instruments for cervical dilation. The commonly used one in clinic is disposable cervical dilator, which consists of a group of expansion rods with diameters ranging from thin to thick. The cross-sectional diameter is constant. The function must start with the expansion rod with a thinner diameter, and it must be replaced until it meets the requirements. The disadvantage is...
