Abstract
The invention discloses a medical inflatable dilator, and belongs to the field of medical instruments. The medical inflatable dilator comprises a dilator body, a connecting tube and an inflating device, wherein the dilator body comprises a hollow tubular air bag made of a soft rubber material, and an operating handle installed in the air bag; the inflating device comprises an inflatable ball and two one-way valves installed at an air inlet and an air outlet of the inflatable ball respectively, wherein an air release valve is also arranged on an air outlet pipe of the inflatable ball; one end of the connecting tube is connected with an air inlet/outlet of the air bag, and the other end of the connecting tube is connected with the air outlet pipe of the inflating device; and the air release valve is positioned between the connecting tube and the one-way valves. As the air bag of the dilator body is made of the soft rubber material, so that soft texture is realized, accordingly the dilator body does not irritate the vaginal wall when entering the vagina, and does not cause discomfort of patients; and after entering the vagina, due to the light weight, the dilator body can be supported on the vagina depending on friction force, so that a doctor does not need to hold the dilator body with hand, and can execute examination with both hands, and the operation is convenient.
Description
Technical field
The present invention relates to a kind of medical aerated dilator, belong to medical instruments field.
Background technology
At present, the vaginal dilator that adopts when obstetrics and gynecology hospital checks is generally the rustless steel manufacturing, mainly there is following several problem: because the dilator that rustless steel is made, quality is hard ice-cold, in use, easily make patient's vaginal mucosa impaired, and patient's vagina is when touching ice-cold dilator, can produce discomfort, impact checks effect; In addition, because the dilator weight of stainless steel is heavier, when checking, the doctor need one to hold handle, a hand inspection, and long-time the use easily makes arm produce feeling of fatigue.
In view of this, the inventor studies this, develops specially a kind of medical aerated dilator, and this case produces thus.
Summary of the invention
The purpose of this invention is to provide a kind of difficult stimulation vaginal wall and medical aerated dilator easy to use.
To achieve these goals, solution of the present invention is:
A kind of medical aerated dilator comprises expansion main body, connection tube and aerating device, and wherein, the expansion main body comprises the hollow tubular air bag made from the soft rubber material and is installed in the interior lever of air bag; Aerating device comprises inflatable ball, and 2 check valves that are installed in respectively on inflatable ball air inlet and the gas outlet, also be provided with vent valve on the escape pipe of inflatable ball, connection tube one end connects advancing/gas outlet of air bag, the other end connects the escape pipe of aerating device, and vent valve is between connection tube and check valve.
The length of described lever is longer than air bag, and the one end sticks on inside air bag by binding agent, and the other end is exposed at the air bag outside, and the doctor will expand main body by lever and import in the body.
As preferably, the hollow tubular air bag of described air bag for making with Emulsoid-film, the two ends of air bag seal by Emulsoid-film.
Described hollow tubular air bag is circular or oval.
Before the expansion main body was not filled with gas, its diameter was about 1 centimetre, stretched into vagina by the lever guiding, after the expansion main body stretches into vagina, doctor's manual squeezing inflatable ball, at this moment, vent valve is closed condition, gas in the inflatable ball enters air bag by connection tube, because be equipped with check valve on inflatable ball air inlet and the gas outlet, can prevent gas backstreaming, along with air is filled with air bag gradually, it is large that its diameter begins to become, and when reaching when checking required diameter, the doctor stops to push inflatable ball; After the doctor checks out, open vent valve, the gas in the air bag is discharged, the diameter that expand main body this moment retracts to about initial 1 centimetre, can extract easily externally, can not give the vaginal wall injury.
Medical aerated dilator of the present invention compared with prior art has the following advantages:
1, since the air bag of expansion main body make with Emulsoid-film, in fill air, quality is soft, can not stimulate vaginal wall when stretching into vagina, and can not make patient feel uncomfortable;
2, after the expansion main body enters vagina, since lightweight, rely on frictional force just can hang on the vagina, the doctor does not need to grasp, and both hands may be used to check, and are easy to operate.
Below in conjunction with drawings and the specific embodiments the present invention is done and to describe in further detail.
Description of drawings
Fig. 1 is the medical aerated dilator structural representation of the present embodiment;
Fig. 2 is the medical aerated dilator expansion body cross-section figure of the present embodiment.
The specific embodiment
As shown in Figure 1, a kind of medical aerated dilator comprises expansion main body 1, connection tube 2 and aerating device 3, and wherein, expansion main body 1 comprises the hollow tubular air bag 11 made from the soft rubber material and the lever 12 that is installed in the air bag 11; Aerating device 3 comprises inflatable ball 31, and 2 check valves 33 that are installed in respectively on inflatable ball 31 air inlets 35 and the gas outlet 36, also be provided with vent valve 34 on the escape pipe 32 of inflatable ball 31, connection tube 2 one ends connect advancing/gas outlet of air bag 11, the other end connects the escape pipe 32 of aerating device 3, and vent valve 34 is between connection tube 2 and check valve 33.
Described lever 12 is an elongated plastic bar, and its length is longer than air bag 11, one ends and is sticked on air bag 11 inside by glue, and the other end is exposed at air bag 11 outsides, and the doctor will expand main body 1 by lever 12 and import in the body.
As shown in Figure 2, in the present embodiment, the hollow elliptical tubulose air bag of described air bag 11 for making with Emulsoid-film, the two ends of the ellipse shape tubulose of air bag 11 hollows seal by Emulsoid-film.Air bag 11 also can be made with other soft rubber materials, as long as make expansion main body and vaginal wall contact portion pliable and tough, has elasticity and harmless getting final product.
The described inflatable ball 31 of the present embodiment is an air bag with air inlet 35 and gas outlet 36, by the manual squeezing air bag, finishes aerification function.The escape pipe 32 of aerating device 3 and expansion the advancing of main body 1/gas outlet link to each other by connection tube 2, before expansion main body 1 is not filled with gas, its diameter is about 1 centimetre, stretch into vagina by lever 12 guiding, after expansion main body 1 stretches into vagina, doctor's manual squeezing inflatable ball 31, at this moment, vent valve 34 is closed condition, and the gas in the inflatable ball 31 enters air bag 11 by connection tube 2, because the air inlet 35 of inflatable ball 31 and gas outlet 36 are provided with check valve 33, can prevent gas backstreaming, along with air is filled with air bag 11 gradually, it is large that its diameter begins to become, when reaching when checking required diameter, the doctor stops to push inflatable ball 31; After the doctor checks out, open vent valve 34, the gases in the air bag 11 are discharged, the diameter that expand main body 1 this moment retracts to about initial 1 centimetre, can extract easily externally, can not give the vaginal wall injury.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present invention to its suitable variation or modification of doing.
