[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0022] Referring to Figures 1-3 , an embodiment provided by the present utility model: An airbag - type cervical dilator with a protection function includes an expansion airbag 1. An expansion frame 2 is fixedly connected to the outer periphery of the expansion airbag 1. A one - way valve 6 is fixedly connected to the left side of the rear end of the expansion airbag 1. The one - way valve 6 is connected to an air inlet pipe 8 through a buckle one 7 and a buckle two 13. An air outlet pipe 4 is fixedly connected to the right side of the rear end of the expansion airbag 1. An operation hole 16 is provided in the middle of the rear side of the expansion airbag 1. A buffer film one 14 is provided on the inner wall of the rear end of the air inlet pipe 8. A plurality of expansion frames 2 located on the outer periphery of the expansion airbag 1. The front ends of the plurality of expansion frames 2 are all rotatably connected to an insertion frame 3. The air outlet pipe 4 fixedly connected to the right side of the rear end of the expansion airbag 1. An air outlet valve 5 is provided at the rear end of the air outlet pipe 4. An inflation airbag 9 is fixedly connected to the rear end of the air inlet pipe 8;
[0023] Specifically, first, by adjusting the angle between the insertion rack 3 and the expansion rack 2, it is convenient to insert the dilator into the patient's cervix. Then, by pressing the air inlet balloon 9, the gas flows into the interior of the intake pipe 8 and then into the interior of the expansion balloon 1 after being buffered by the first buffer membrane 14. By varying the pressure applied to the interior of the air inlet balloon 9, the first buffer membrane 14 changes the aperture size according to the gas volume and flow rate, achieving the mitigation of the gas generated by pressing, avoiding excessive gas flowing into the interior of the expansion balloon 1 and causing the sudden expansion of the expansion balloon 1 to drive the sudden expansion of the expansion rack 2, which would cause pain to the patient and affect the patient's usage experience, thus protecting the patient. At the same time, the gas flowing into the expansion balloon 1 fills the interior of the expansion balloon 1 through the function of the one-way valve 6 to prevent air leakage. After the expansion balloon 1 expands, it drives the expansion rack 2 to prop up the patient's cervix, facilitating medical staff to perform operations on its interior through the operation hole 16. After the operation is completed, the gas inside the expansion balloon 1 can be discharged by opening the air outlet valve 5, facilitating the removal of the dilator. Also, when the intake pipe 8 is damaged, the intake pipe 8 can be quickly replaced by opening the first buckle 7 and the second buckle 13, which helps improve the work efficiency of repairing and replacing the intake pipe 8.
[0024] Two sealing rings 12 are respectively fixedly connected to the rear end of the one-way valve 6 and the front end of the intake pipe 8. A first buckle 7 is arranged on the upper side of the two sealing rings 12, and a second buckle 13 is arranged on the lower side of the two sealing rings 12. The left and right ends of the second buckle 13 and the first buckle 7 are connected by a locking component. Four locking blocks 10 are respectively fixedly connected to the left and right ends of the first buckle 7 and the second buckle 13. The outer walls of the upper locking block 10 and the lower locking block 10 are threadedly connected with a lock shell 11. A first buffer membrane 14 is fixedly connected to the inner wall of the rear end of the intake pipe 8. A second buffer membrane 15 is arranged behind the first buffer membrane 14;
[0025] Specifically, the aperture of the first buffer membrane 14 is smaller than that of the second buffer membrane 15. At the same time, both the first buffer membrane 14 and the second buffer membrane 15 are elastic and can scale, achieving more effective buffering of the gas generated by the air inlet balloon 9, controlling the gas flow rate and volume flowing into the intake pipe 8, avoiding excessive gas volume and flow rate flowing into the intake pipe 8 and the interior of the expansion balloon 1, which would cause the sudden expansion of the expansion balloon 1 and cause pain to the patient, thus protecting the patient. Also, when the intake pipe 8 is damaged, after unscrewing the lock shell 11 from the outer wall of the locking block 10, the intake pipe 8 and the one-way valve 6 can be disassembled by opening the first buckle 7 and the second buckle 13, facilitating the quick replacement of the intake pipe 8 and improving the work efficiency of replacing and repairing the intake pipe 8.
[0026] Working principle: First, by adjusting the angle between the insertion frame 3 and the expansion frame 2, it is convenient to insert the dilator into the cervix of the patient. Then, by pressing the inflation balloon 9, the gas flows into the interior of the intake pipe 8 and then into the interior of the expansion balloon 1 after being buffered by the first buffer membrane 14 and the second buffer membrane 15. By varying the pressure applied to the interior of the inflation balloon 9, the first buffer membrane 14 and the second buffer membrane 15 change the aperture size according to the gas volume and flow rate, achieving the mitigation of the gas generated by pressing, avoiding excessive gas flowing into the interior of the expansion balloon 1, which may cause the sudden expansion of the expansion balloon 1 and drive the sudden expansion of the expansion frame 2, causing pain to the patient and affecting the patient's usage experience, thus protecting the patient. At the same time, the gas flowing into the expansion balloon 1 makes the gas fill the interior of the expansion balloon 1 through the function of the one-way valve 6 to avoid air leakage. After the expansion balloon 1 expands, it drives the expansion frame 2 to prop up the cervix of the patient, facilitating the medical staff to operate on the interior through the operation hole 16. After the operation is completed, the gas inside the expansion balloon 1 can be discharged by opening the air outlet valve 5, facilitating the removal of the dilator. At the same time, when the intake pipe 8 is damaged, the lock shell 11 can be unscrewed from the outer wall of the lock block 10, and then the intake pipe 8 and the one-way valve 6 can be disassembled by opening between the first buckle 7 and the second buckle 13, realizing the quick replacement of the intake pipe 8 and facilitating the improvement of the work efficiency of the repair and replacement of the intake pipe 8.
[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
