Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a uterine cavity perfusion device. Background Technology

[0002] Intrauterine irrigation generally refers to the injection of medication or saline solution into the uterine cavity under ultrasound guidance through a specially designed connecting tube to treat certain diseases or diagnose certain intrauterine lesions. During the irrigation, the liquid in the syringe is pushed into the connecting tube and then into the uterine cavity. After all the liquid in the syringe is squeezed out, there is still liquid in the connecting tube, resulting in residual medication and affecting the treatment effect. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where, after all the liquid in the syringe is squeezed out and injected, there is still liquid in the connecting tube, resulting in residual medication and affecting the treatment effect. Therefore, this invention proposes a uterine cavity irrigation device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a uterine cavity irrigation device, including an injection cylinder, a connecting tube connected to the injection cylinder, a piston abutting inside the injection cylinder, a movable rod fixedly connected to the piston, the movable rod being fixed by a fixing mechanism, a conduit connected to the connecting tube, a connecting shell connected to the conduit, a movable plug abutting inside the connecting shell, the movable plug being moved by a moving mechanism, and a valve provided on the conduit.

[0006] Preferably, the fixing mechanism includes a fixing frame, which is fixedly connected to the injection cylinder, and a threaded post is threadedly connected to the fixing frame.

[0007] Preferably, a knob is fixedly connected to one end of the threaded column, and an abutment block is fixedly connected to the other end.

[0008] Preferably, a blocking part is fixedly connected to the connecting pipe.

[0009] Preferably, the moving mechanism includes a threaded rod, one end of which is fixedly connected to the moving plug, and the other end of which is threadedly connected to a threaded cylinder. The threaded cylinder is rotatably connected to a fixed lug via a bearing, and the fixed lug is fixedly connected to the injection cylinder.

[0010] Preferably, a limiting rod is fixedly connected to the movable plug, and a limiting hole is formed on the fixed ear, through which the limiting rod passes.

[0011] Preferably, the injection cylinder and the connecting shell are made of transparent plastic.

[0012] The uterine cavity irrigation device proposed in this utility model has the following advantages: by moving the moving plug through the moving mechanism, air is allowed to enter the connecting tube, which in turn pushes the liquid in the connecting tube to flow into the uterine cavity, thus avoiding the situation where there is still liquid in the connecting tube, which would lead to drug residue.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-4 A uterine cavity irrigation device includes an injection cylinder 3, a connecting tube 1 connected to the injection cylinder 3, a piston 9 abutting inside the injection cylinder 3, a movable rod 8 fixedly connected to the piston 9, and the movable rod 8 fixed by a fixing mechanism. A conduit 5 is connected to the connecting tube 1, and a connecting shell 4 is connected to the conduit 5. The connecting shell 4 is fixedly connected to the injection cylinder 3. The injection cylinder 3 and the connecting shell 4 are made of transparent plastic. A movable plug 11 abutting inside the connecting shell 4 is moved by a moving mechanism. A valve is provided on the conduit 5. When the liquid in the injection cylinder 3 is pushed out by the piston 9, the moving mechanism drives the movable plug 11 to move, allowing air to enter the connecting tube 1 and push the liquid in the connecting tube 1 to flow into the uterine cavity, thus avoiding the situation where there is still liquid in the connecting tube 1, resulting in drug residue.

[0020] A blocking part 2 is fixedly connected to the connecting tube 1. The blocking part 2 is made of silicone material and contacts the uterine cavity opening to block the uterine cavity opening and prevent the medicine from flowing out.

[0021] The moving mechanism includes a threaded rod 12, one end of which is fixedly connected to the moving plug 11, and the other end of which is threadedly connected to a threaded cylinder 13. The threaded cylinder 13 is rotatably connected to a fixed ear 15 via a bearing. The fixed ear 15 is fixedly connected to the injection cylinder 3. By rotating the threaded cylinder 13, the position of the adjusting threaded rod 12 in the threaded cylinder 13 is adjusted, thereby driving the moving plug 11 to move and squeezing the air in the connecting shell 4 into the connecting tube 1.

[0022] Example 2: In Example 1, when the moving mechanism drives the moving plug 11 to move, air pushes the piston 9, causing the piston 9 to move, which affects the extrusion of residual medicine. (Refer to...) Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the fixing mechanism includes a fixing frame 6, which is fixedly connected to the injection cylinder 3. A threaded post 7 is threaded through the fixing frame 6. A knob is fixedly connected to one end of the threaded post 7 and an abutment block 10 is fixedly connected to the other end. By rotating the threaded post 7, the abutment block 10 is abutted against the moving rod 8, which will fix the position of the piston 9 and prevent the piston 9 from moving.

[0023] In use, by inserting the connecting tube 1 into the uterine cavity, the blocking part 2 seals the uterine cavity. After the liquid is completely pushed out by the piston 9 by pushing the moving rod 8, the abutment block 10 is pressed against the moving rod 8 by rotating the threaded column 7, which fixes the position of the piston 9. Then, the valve is opened and the threaded cylinder 13 is rotated to adjust the position of the adjusting threaded rod 12 in the threaded cylinder 13, thereby driving the moving plug 11 to move, squeezing the air in the connecting shell 4 into the connecting tube 1, and pushing the liquid in the connecting tube 1 to move into the uterine cavity.

[0024] Example 3: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, a limiting rod 14 is fixedly connected to the movable plug 11, and a limiting hole is opened on the fixed ear 15. The limiting rod 14 passes through the limiting hole. By using the limiting rod 14 and the limiting hole, the movable plug 11 is limited, preventing the threaded rod 12 from rotating when the threaded cylinder 13 is rotated.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
