Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a vaginal douche for cervical cancer radiotherapy. Background Art

[0002] During the process of cervical cancer radiotherapy, the vagina needs to be washed and cleaned multiple times a day. However, the existing douche is simply rod-shaped, and during the washing process, the washing fluid is likely to flow into the uterine cavity, thus affecting the health of the patient. At the same time, since the used washing fluid needs to be drained and new washing fluid needs to be injected multiple times during the washing process, in the existing technology, when draining the used washing fluid, the douche needs to be taken out from the patient's vagina, and after draining, the douche is inserted into the patient's vagina again to inject new washing fluid.

[0076] Based on the above, by arranging the airbag 101 at the front end of the inflator, after inserting the flushing tube 10 into the patient's vagina during use, the airbag 101 can be inflated through the inflatable airbag 101 to make the airbag 101 bulge, thereby closing the patient's vagina to prevent the flushing liquid from entering the uterine cavity during flushing. After the inflation of the airbag 101 is completed, the adjustment can be carried out through the adjusting member to connect the first drainage tube 301 and the flushing tube 10. In this way, by squeezing the inflatable balloon 30, the flushing liquid in the liquid storage device 302 can be sent into the flushing tube 10 to flush the patient's vagina. After the flushing is completed, the control valve 402 of the second drainage tube 401 can be opened, and the flushing liquid in the patient's vagina can be drawn out through the negative pressure bottle 40. In this way, it is possible to replace the flushing liquid without pulling out the flushing tube 10. The operation is simple, the flushing is fast, time-saving and labor-saving, greatly reducing the workload of medical staff.

[0077] Preferably, in an embodiment of the present invention, the adjusting member 20 includes a first connecting member 201 and a second connecting member 202.

[0080] In this way, since the upper end of the second connecting member 202 is slidably arranged in the second installation groove 2012, then the connection between the first drainage tube 301 and the air guide tube 102 or the flushing tube 10 can be adjusted by adjusting the position of the second connecting member 202 in the second installation groove 2012.

[0081] Preferably, in an embodiment of the present invention, a connecting tube 20111 is provided in the middle of the bottom of the first installation groove 2011. The upper end of the connecting tube 20111 is communicated with the air guide tube 102. A first through hole 20121 is provided in the middle of the bottom of the second installation groove 2012. The first through hole 20121 is communicated with the connecting tube 20111. The diameter of the first through hole 20121 is smaller than the diameter of the connecting tube 20111. A plurality of second through holes 20122 are distributed around the first through hole 20121. The upper and lower ends of the second through holes 20122 respectively penetrate through the first installation groove 2011 and the second installation groove 2012;

[0082] A cavity is formed inside the lower end of the second connecting member 202. A flow passage 2021 is provided in the middle of the second connecting member. The flow passage 2021 communicates with the cavity. A plurality of conical protrusions 2022 are provided at intervals on the upper end surface of the second connecting member 202.

An extension portion 2024 is provided in the middle of the upper end surface of the second connecting member 202. The upper end of the extension portion 2024 is inserted into the connecting pipe 20111. A sealing piece 2025 is provided at the upper end of the extension portion 2024;

[0083] When the conical protrusion 2022 is inserted into the second through hole 20122, the first drainage tube 301 communicates with the air guide tube 102. When the conical protrusion 2022 is located above the second through hole 20122, the first drainage tube 301 communicates with the flushing tube 10.

[0084] Based on the above, since the lower end of the second connecting member 202 is inserted into the second installation groove 2012, and the upper end of the connecting pipe 20111 communicates with the air guide tube 102, and a first through hole 20121 is provided in the middle of the bottom of the second installation groove 2012, and the first through hole 20121 communicates with the connecting pipe 20111, then, so that the air guide tube 102 communicates with the second installation groove 2012. At the same time, since a cavity is formed inside the lower end of the second connecting member 202, a flow passage 2021 is provided in the middle of the second connecting member, the flow passage 2021 communicates with the cavity, and a plurality of third through holes 2023 are distributed on the upper end surface of the second connecting member 202, and the plurality of third through holes 2023 all penetrate into the cavity, then, it can be made that the first drainage tube 301 communicates with the air guide tube 102, so as to inflate the airbag 101 through the inflation balloon 30;

Then, when the second connecting member 202 moves downward, the sealing piece 2025 can seal the first through hole 20121. At this time, communication between the first drainage pipe 301 and the air guide pipe 102 is cut off. At the same time, since a plurality of second through holes 20122 are distributed around the first through hole 20121, and a plurality of conical protrusions 2022 are arranged at intervals on an upper end surface of the second connecting member 202. Then, when the sealing piece 2025 seals the first through hole 20121, the conical protrusions 2022 are located above the second through holes 20122. At this time, the first drainage pipe 301 is communicated with the flushing pipe 10, and the flushing liquid in the liquid storage device 302 can be conveyed into the vagina of a patient through the inflation balloon 30 for flushing;

[0086] On the contrary, when the second connecting member 202 moves upward, the sealing piece 2025 moves away from the first through hole 20121, and the conical protrusions 2022 are inserted into the second through holes 20122 to seal the second through holes 20122.
