Abstract
The utility model discloses a cervical dilator, which comprises a water pipe (1), wherein the water pipe (1) is divided into a blind end and a water injection end. A water bag (2) is attached to an outer wall of the water pipe (1), the water pipe (1) is provided with a water sucking hole (3) to be communicated with the water bag (2), and water sucking expansion materials (4) are contained in the water bag (2). Because the structure is adopted, water is injected from a water injection port when in use, the water sucking expansion materials in the water bag expand quickly after sucking water, and when the water bag expands to a required dimension, cervical dilating operation can be finished by stopping water injection. The cervical dilator has the advantages of adopting a relatively simple structure to achieve one-time continuous dilatation of the cervix, being low in production cost and simple to operate, avoiding possibility of iatrogenic infection caused by repeated operation, and greatly relieving pain of patients.
Description
Technical field
This utility model relates to the cervical dilator that a kind of gynecilogical operation is used, and specifically is a kind of cervical dilator of a persistence cervix dilating.
Background technology
Cervical dilator is gynecilogical operation apparatus, particularly artificial abortion's art commonly used, examines erasion, hysteroscope operation, all must the expansion of temporary dwelling palace neck before the art.The present clinical cervical dilator that uses is the expansion metal rod, divides the size that varies in size to expand the palace successively, and patient's pain is obvious when changing bigger yardage uterine-expanding rod, and repeatable operation like this, causes that the probability of nosocomial infection also can increase.Particularly hysteroscope operation is popularized, and requires the about 10 ~ 10.5mm of cervix dilating before the hysteroscope operation, if the cervix dilating failure, hysteroscope operation also just can't be accomplished smoothly.So press for an a kind of persistence cervix dilating, and can alleviate the cervical dilator of patient's pain.
The utility model content
This utility model technical issues that need to address provide a kind of economic health, and safety simple to operate is little to the patient body damage, the cervical dilator of a persistence cervix dilating that can ease the pain.
For solving the problems of the technologies described above; The technical scheme that this utility model adopts is: cervical dilator, comprise a water service pipe, and water service pipe one end is the water filling end; The other end is a cecum; The outer wall of water service pipe has been set up water pocket, and the water service pipe tube wall is provided with the suction hole that is communicated with water service pipe inside and water pocket, and water pocket includes water uptake expansion material.
Described water uptake expansion material is sodium polyacrylate and dry pulp.
Described water uptake expansion material is sodium polyacrylate and non-woven fabrics.
Described water pocket is a silica gel material.
Owing to adopted above-mentioned structure; By the water filling end water filling of water service pipe, the suction hole of water on the water service pipe tube wall enters in the water pocket during use, expands rapidly in the water uptake expansion material suction back in the water pocket; When water pocket is expanded to the yardstick that needs, stop water filling and promptly accomplish the operation of expansion palace.The utlity model has following beneficial effect: adopted simple relatively structure to realize a persistence expansion of cervix uteri; Production cost is low; Simple to operate, avoided having alleviated patient's pain significantly because of repeatable operation causes the possible of nosocomial infection.

The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing this utility model.
As shown in Figure 1, the described cervical dilator of this utility model comprises a water service pipe 1; Water service pipe 1 one ends are the water filling end; The other end is a cecum, and the outer wall of water service pipe 1 has been set up water pocket 2, and water pocket 2 is looped around the periphery of water service pipe 1; Water service pipe 1 tube wall is provided with the suction hole 3 that is communicated with water service pipe 1 inside and water pocket 2, and water pocket 2 includes water uptake expansion material 4.Water service pipe 1 is made by silica gel material with water pocket 2, and both can be and are made into integration.Water uptake expansion material 4 is that sodium polyacrylate adds dry pulp or non-woven fabrics and so on, and wherein, sodium polyacrylate is a kind of nontoxic macromolecule water uptake material, and dry pulp or non-woven fabrics are to be used for plastotype sodium polyacrylate expanded shape.During use; By the water filling port water filling, in the water pocket 2 expand rapidly in water uptake expansion material 4 suction backs, and the expansion yardstick is by the injection liquid volume control of syringe labelling; The shape of water pocket receives dry pulp or non-woven fabrics and so on plastotype after expanding; It is indeformable not rebound, and when being expanded to the yardstick that needs, stopping water filling and promptly accomplishes the operation of expansion palace.
In a word; The above-mentioned preferred implementation though this utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of this utility model only if such variation and remodeling have departed from the scope of this utility model.
Claims (4)
