Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in figure 1, the size-adjustable medical mouth gag comprises a mouth-opening air bag 1 and an inflating air bag 2. The expansion state of the mouth-opening air bag 1 is a circular truncated cone shape with a small front part and a large rear part. The inflatable balloon 2 is connected with the rear end of the mouth opening air bag 1 through an inflatable tube 3 and repeatedly presses the mouth opening air bag 1 to input air, so that the mouth opening air bag 1 expands in the oral cavity of a patient to achieve mouth opening exercise of the patient. The outer side wall of the rear part of the mouth-opening air bag 1 is provided with a circle of groove 9 for the occlusion of the teeth of a patient, the rear end of the mouth-opening air bag is also provided with an exhaust pipe 10, and the exhaust pipe is provided with a valve for blocking or conducting the exhaust pipe. An air inlet pipe 4 for sucking air into the inflatable balloon 2 is arranged on the inflatable balloon, and flow restrictors 5 for limiting the air to flow forwards in one direction only along the direction from the inflatable balloon 2 to the mouth-opening airbag 1 are respectively fixed in the air inlet pipe 4 and the inflatable pipe 3.
As shown in fig. 2, the flow restrictor 5 is made of an elastic silicone material and has a tip facing the inflatable balloon 2 in the air inlet tube 4 or facing the mouth-opening balloon 1 in the inflation tube 3. The two opposite sides of the flow restrictor 5 are thick circular arc wall structures 6, the other two opposite sides of the flow restrictor 5 are inclined thin-plate structures 7, one ends of the inclined thin-plate structures 7 are mutually butted and form the tip of the flow restrictor 5, and then the ends of the inclined thin-plate structures 7 which are mutually butted are spread by air when the air flows along the direction from the inflatable balloon 2 to the flaring balloon 1 so as to continue to flow forwards.
As shown in fig. 3-5, a shoulder structure 8 protruding outward is disposed at a larger end of the flow restrictor 5, clamping grooves matched with the shoulders are disposed on the inner walls of the air inlet tube 4 and the air charging tube 3 at positions corresponding to the shoulders, and the flow restrictor 5 is fixedly mounted in the air inlet tube 4 and the air charging tube 3 through the matching between the shoulders and the clamping grooves.
When using the mouth gag, the uninflated and expanded mouth gag 1 is first placed in the mouth of the patient and the patient's teeth are guaranteed to align and bite into the groove 9 at the back of the mouth gag 1. Then, the open-mouthed balloon 1 is inflated by repeatedly pressing the inflatable balloon 2. When pressing inflatable balloon 2, its inside gas can get into gas tube 3 and intake pipe 4:
when the air entering the inflation tube 3 reaches the position of the flow restrictor 5 in the inflation tube 3, the end parts of the inclined sheet structures 7 at two sides of the flow restrictor 5, which are abutted against each other, are expanded outwards under the action of air pressure, and then the end parts of the inclined sheet structures 7, which are abutted against each other, are expanded by the air (the thick arc wall structure 6 has a certain thickness and has non-deformation strength). Therefore, the air introduced into the inflation tube 3 smoothly enters the open-mouthed airbag 1 through the flow restrictor 5 in the inflation tube 3 to inflate the open-mouthed airbag 1.
When the air entering the air inlet pipe 4 reaches the position of the flow restrictor 5 in the air inlet pipe 4, the end parts of the inclined sheet structures 7 at the two sides of the flow restrictor 5, which are mutually abutted, can be inwardly shrunk and attached under the action of air pressure, so that the end parts of the inclined sheet structures 7, which are mutually abutted, can seal the tip end of the flow restrictor 5, finally, the air cannot be discharged from the air inlet pipe 4, and when the inflatable balloon 2 is pressed, the air in the air inlet pipe 4 can completely enter the flaring balloon 1.
After pressing the inflatable balloon 2, it recovers its original shape while sucking air. With the same principle, in the process of air suction of the inflatable balloon 2, external air can smoothly enter the inflatable balloon through the flow restrictor 5 in the air inlet pipe 4, and meanwhile, air cannot flow back from the mouth-opening airbag 1 through the air inlet pipe 4. Therefore, the inflation of the open-mouthed airbag 1 can be achieved by repeatedly pressing the inflatable balloon 2.
The mouth-opening air bag 1 can be continuously expanded along with the inflation, when the mouth-opening air bag is expanded to meet the mouth-opening exercise requirement, the inflation of the mouth-opening air bag 1 by pressing the inflatable air bag 2 can be stopped, and the mouth-opening exercise can be started at the moment. After the mouth opening exercise is finished, the valve on the exhaust pipe 10 is opened, the gas in the mouth opening air bag 1 is exhausted, and the mouth opening air bag 1 is taken out from the oral cavity of the patient after being contracted.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
