[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a hysterosalpingography tube. Background Art

[0002] The hysterosalpingography tube is a tool used for hysterosalpingography. Contrast agent is injected into the uterine cavity and fallopian tubes through a catheter. The flow of contrast agent through the uterine cavity and fallopian tubes is then observed using X-rays. The patency of the fallopian tubes, the location of obstruction, and the morphology of the uterine cavity are analyzed based on the imaging results.

[0003] In the prior art, a disposable intrauterine hydrotubation tube is required for hysteroscopic and laparoscopic treatment of infertility-related diseases. However, after the catheter of the existing disposable intrauterine hydrotubation tube is filled with water, its water control structure is easy to loosen and fall off, resulting in water leakage and reflux after water injection. In addition, when clinicians perform tubal hydrotubation treatment, they often need to clamp the catheter with curved forceps. This operation requires the cooperation of doctors and nurses, thereby increasing the workload of medical staff and the frequency of glove changes. In addition, cross-operation of medical staff increases the risk of surgical incision infection.

[0004] Therefore, a hysterosalpingography tube is needed to solve the problem that the catheter in the prior art is prone to reflux during use, causing inconvenience to medical staff. Utility Model Content

[0007] It should be noted in the scheme that the anti-backflow mechanism includes two connecting rods rotatably connected to the bottom surface of the moving rod, and two symmetrically arranged sliding grooves are opened on one side of the inner wall of the connecting sleeve corresponding to the movable groove. Slide blocks are fixed to the top surfaces of the two baffles, and the slide blocks are slidably connected to the inner walls of the sliding grooves. The bottom end of the connecting rod is rotatably connected to the top end of the slide block, and a second spring is fixed on the side of the two baffles that are away from each other, and the end of the second spring is fixed to the inner wall of the movable groove.

[0008] It is further worth explaining that the elastic component includes two fixed rods respectively fixed on both sides of the inner wall of the connecting sleeve, and a fixing ring is fixed on the end of the two fixed rods that is close to each other. The fixing ring is movably sleeved on the outer surface of the movable rod, and the outer surface of the movable rod is sleeved with a first spring. The top end of the first spring is fixed to the bottom surface of the resistance plate, and the bottom end of the first spring is fixed to the top surface of the fixing ring.

[0009] It should be further explained that a protrusion is fixed on the top surface of the abutment plate, and a cross-shaped through hole is opened on the surface of the protrusion.

[0010] As a preferred embodiment, a groove matching with the abutment disc is formed on one side of the inner wall of the connecting sleeve.

[0011] As a preferred implementation, a liquid inlet pipe is fixed to the liquid inlet end of the connecting sleeve.

[0012] Compared with the prior art, the hysterosalpingography tube provided by the utility model has at least the following beneficial effects:

[0013] (1) The injection head pushes the disc inward, so that the moving rod pushes the two connecting rods to move. The lower ends of the two connecting rods unfold and drive the two sliders to slide in the slide groove, so that the two baffles open, thereby infusing the branch tube. After the injection is completed, under the elastic force of the second spring, the two baffles are pushed to close and reset, thereby closing the liquid outlet to prevent backflow. At the same time, under the elastic force of the first spring, the disc is pushed against the inner wall of the connecting sleeve, so that the connecting sleeve remains in a closed state when not injecting. At the same time, it cooperates with the anti-backflow mechanism to further prevent liquid reflux, which brings convenience to the operation of medical staff while reducing the risk of cross infection.

[0014] (2) By matching the card slot with the resist disk, when not injecting, the resist disk is pressed in the card slot under the elastic force of the first spring, so as to better seal the connecting sleeve and improve the sealing performance of the resist disk, so that the liquid inlet tube can better cooperate with the injection head and improve the stability of the injection head when inserted for injection.

[0022] Further Figure 2 and Figure 3 As shown, it is worth specifically explaining that the backflow prevention mechanism includes two connecting rods 13 rotatably connected to the bottom surface of the movable rod 12, and two symmetrically arranged slide grooves 19 are opened on one side of the inner wall of the connecting sleeve 3 corresponding to the movable groove 17. The top surfaces of the two baffles 15 are fixed with sliders 16, and the sliders 16 are slidably connected to the inner walls of the slide grooves 19. The bottom ends of the connecting rods 13 are rotatably connected to the top ends of the sliders 16. The sides of the two baffles 15 that are away from each other are fixed with second springs 18, and the ends of the second springs 18 are fixed to the inner walls of the movable grooves 17. When the injection head is injecting, it pushes the disc 8 to move inward, thereby driving the movable rod 6 to move, so that the movable rod 12 pushes the two connecting rods 13 to move, and the lower ends of the two connecting rods 13 unfold and drive the two sliders 16 to slide in the slide grooves 19, so that the two baffles 15 are opened, thereby infusing the branch tube 2.

[0023] Further Figure 2 and Figure 4As shown, it is worth explaining in detail that the elastic component includes two fixed rods 4 respectively fixed on both sides of the inner wall of the connecting sleeve 3, and a fixing ring 5 is fixed at one end of the two fixed rods 4 that is close to each other. The fixing ring 5 is movably sleeved on the outer surface of the movable rod 6, and the outer surface of the movable rod 6 is sleeved with a first spring 7. The top end of the first spring 7 is fixed to the bottom surface of the resistance plate 8, and the bottom end of the first spring 7 is fixed to the top surface of the fixing ring 5. Under the elastic force of the first spring 7, the resistance plate 8 is pushed against the inner wall of the connecting sleeve 3, so that the connecting sleeve 3 remains in a closed state when not injecting, and at the same time cooperates with the anti-backflow mechanism to further prevent liquid reflux.

[0024] Further Figure 2 As shown, it is worth explaining in detail that a protrusion 9 is fixed to the top surface of the disc 8, and a cross-shaped through hole 10 is opened on the surface of the protrusion 9. When the injection head is inserted into the connecting sleeve 3, the liquid outlet end of the injection head abuts against the end of the protrusion 9, thereby better pushing the disc 8 to move, thereby opening the connecting sleeve 3 for liquid injection, wherein the cross-shaped through hole 10 facilitates the outflow of the injection liquid.

[0025] This scheme has the following working process: after the catheter 1 of the existing disposable intrauterine hydroanatomy tube is filled with water, its water control structure is easy to loosen and fall off, causing leakage and reflux after water injection, and when clinical doctors perform tubal hydrotherapy, they often need to clamp the catheter 1 with curved forceps. This operation requires the cooperation of doctors and nurses, thereby increasing the workload of medical staff and the frequency of changing gloves, and the cross-operation of medical staff increases the risk of surgical incision infection. When the injection head is inserted into the connecting sleeve 3, the liquid outlet end of the injection head abuts against the end of the protrusion 9, thereby better pushing the disc 8 to move, thereby opening the connecting sleeve 3 for injection, wherein the cross-shaped through hole 10 is convenient for injection When the injection head is inserted into the connecting sleeve 3, the receiving plate 8 is pushed inward to move, thereby driving the movable rod 6 to move, so that the movable rod 12 pushes the two connecting rods 13 to move, and the lower ends of the two connecting rods 13 are unfolded and drive the two sliders 16 to slide in the slide groove 19, so that the two baffles 15 are opened, so as to infuse the branch tube 2. After the injection, the injection head is pulled out, and under the elastic force of the second spring 18, the two baffles 15 are pushed to close and reset, thereby closing the liquid outlet 14 to prevent backflow. At the same time, under the elastic force of the first spring 7, the receiving plate 8 is pushed against the inner wall of the connecting sleeve 3, so that the connecting sleeve 3 remains closed when not injecting.

[0026] According to the above working process, it can be known that: during the process of inserting the injection head into the connecting sleeve 3, the anti-disk 8 will be pushed to move inward, thereby driving the movable rod 6 to move, so that the movable rod 12 pushes the two connecting rods 13 to move, and the lower ends of the two connecting rods 13 are unfolded and drive the two sliders 16 to slide in the slide groove 19, so that the two baffles 15 are opened, thereby infusing the branch tube 2. After the injection is completed, under the elastic force of the second spring 18, the two baffles 15 are pushed to close and reset, thereby closing the liquid outlet 14 to prevent backflow. At the same time, under the elastic force of the first spring 7, the anti-disk 8 is pushed against the inner wall of the connecting sleeve 3, so that the connecting sleeve 3 remains in a closed state when not injecting, and cooperates with the anti-backflow mechanism to further prevent liquid reflux, which brings convenience to the operation of medical staff while reducing the risk of cross infection.

[0027] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that a slot 20 matching with the disc 8 is provided on one side of the inner wall of the connecting sleeve 3, wherein the slot 20 is adapted to the disc 8.
