[0002] In the medical imaging department, there are many uterine and fallopian tube contrast examinations. In the current uterine and fallopian tube contrast examinations, it is necessary to place the contrast infusion tube into the patient's body, and then deliver the contrast agent to the patient's body through an external pipeline before the contrast work can be carried out.

[0003] In the prior art, after the contrast agent is delivered to the patient's body through the pipeline, there will still be a phenomenon of liquid residue inside the pipeline. Since the infusion connecting tube is directly connected to the pipeline of the infusion pump, the liquid medicine inside the infusion connecting tube is likely to flow back into the pipeline of the infusion pump, resulting in liquid medicine pollution and reducing the safety of using medical devices.

[0004] In summary, the utility model provides an adapter device for a contrast infusion connecting tube and an infusion pump pipeline to solve the above problems. Content of the Utility Model

Inside the threaded channel at the top end of the connecting sleeve and at the bottom end of the delivery pipe, a first mounting ring is embedded. The bottom end of the connecting sleeve is threadedly connected to the top end of the liquid outlet pipe. Inside the threaded channel at the bottom end of the connecting sleeve and at the top end of the liquid outlet pipe, a second mounting ring is embedded. A stainless steel filter screen is embedded in the inner ring surface of the first mounting ring, and a silicone sealing layer is embedded in the inner ring surface of the second mounting ring.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] See also Figures 1-5, the present utility model provides a technical solution: a transfer device for a contrast infusion connecting tube and an infusion pump pipeline, including a main conduit 1, a branch conduit 2 and a pipe joint 5.

The end of the branch conduit 2 far from the main conduit 1 is connected to a second threaded pipe head 4. The pipe joint 5 is threadedly connected to the bottom end of the main conduit 1. The bottom end of the pipe joint 5 is threadedly connected to a connecting tube 6. The bottom end of the connecting tube 6 is connected to a delivery tube 7. The bottom end of the delivery tube 7 is connected to a filtrating component 8. The bottom end of the filtrating component 8 is threadedly connected to a liquid outlet tube 9. Through an external infusion pump, the contrast agent for uterine and fallopian tube imaging can be directly pumped into the interior of the branch conduit 2 and the main conduit 1, and the contrast agent is sequentially transported from the main conduit 1 to the interior of the connecting tube 6, the delivery tube 7, the filtrating component 8 and the liquid outlet tube 9 for discharge. The bottom end of the liquid outlet tube 9 is connected to the port of a rubber thin tube in the patient's body, so that the contrast agent can be transported into the patient's body. Using an infusion pump to automatically inject the drug instead of the current manual injection of the drug by a special person during the contrast examination can avoid the radiation damage to the injection personnel. Moreover, after connecting the infusion pump to automatically inject the drug through this transfer device, during the uterine and fallopian tube imaging examination, the injection flow rate, control switch can be set according to the patient's condition, and the infusion pump will automatically alarm when the pressure is too high, solving the problem of uneven manual injection flow rate, improving the safety of the patient. The whole device is made of ABS material, acid and alkali resistant, high temperature resistant, high pressure resistant, sterilized by plasma, safe and economical, simple to operate, pollution-free, compatible with various size specifications, effectively reducing the consumables. The top end of the main conduit 1 is threadedly connected to the infusion pipeline of the external infusion pump through the first threaded pipe head 3. The branch conduit 2 is threadedly connected to the infusion pipeline of the external infusion pump through the second threaded pipe head 4. The pipe joint 5 is connected to the connecting tube 6, and the pipe joint 5 is connected to the main conduit 1.

[0027] Please refer to Figures 2-3 , the filtrating component 8 includes a connecting sleeve 81. The top end of the connecting sleeve 81 is threadedly connected to the bottom end of the delivery tube 7. Inside the threaded channel at the top end of the connecting sleeve 81 and at the bottom end of the delivery tube 7, a first mounting ring 82 is embedded. The bottom end of the connecting sleeve 81 is threadedly connected to the top end of the liquid outlet tube 9. Inside the threaded channel at the bottom end of the connecting sleeve 81 and at the top end of the liquid outlet tube 9, a second mounting ring 84 is embedded. Inside the inner ring surface of the first mounting ring 82, a stainless steel filter screen 83 is embedded. Inside the inner ring surface of the second mounting ring 84, a silica gel sealing layer 85 is embedded. The pore diameter of the filter holes of the stainless steel filter screen 83 is 20um - 30um, which can filter the incompletely fused powder lumps in the contrast agent and the fine glass slag mixed into the medicine water during the opening process of the ampoule bottle.

[0028] Please refer to Figures 2-3, the top end of the connecting sleeve 81 is connected to the bottom end of the delivery pipe 7, and the bottom end of the connecting sleeve 81 is connected to the top end of the liquid outlet pipe 9. The outer ring surfaces of the first mounting ring 82 and the second mounting ring 84 at the separated ends are both convex rings. The outer diameters of the first mounting ring 82 and the second mounting ring 84 are both larger than the inner diameter of the connecting sleeve 81. By rotating the connecting sleeve 81 in the reverse direction, the connecting sleeve 81 can be detached from the bottom end of the delivery pipe 7, and the impurities filtered out at the top of the stainless steel filter screen 83 can be cleaned. Moreover, by rotating the connecting sleeve 81 and the liquid outlet pipe 9 in the reverse direction, the entire filtrate pipe fitting 8 can be detached, which is convenient for disinfection and cleaning.

[0029] Please refer to Figures 3-5 , the top end of the first mounting ring 82 is connected to the bottom end of the second mounting ring 84. A cross cut is provided between the top and bottom of the center of the silicone sealing layer 85. When the device does not deliver the contrast agent as a whole, the cross cut of the silicone sealing layer 85 will be in a closed state. When the device is delivering the contrast agent, the water flow pumped by the external infusion pump will impact and open the cross cut of the silicone sealing layer 85, opening the infusion channel for the normal delivery of the contrast agent. When the infusion pump stops delivering, the cross opening of the silicone sealing layer 85 will automatically close due to the deformation recovery ability of the silicone, thereby blocking the channel between the liquid at the liquid outlet pipe 9 and the delivery pipe 7, avoiding the phenomenon of liquid backflow inside the liquid outlet pipe 9, and reducing the drug contamination generated during the uterine and fallopian tube imaging.

[0030] Specific implementation method: The contrast agent for uterine and fallopian tube imaging can be directly pumped into the interior of the branch pipe 2 and the main pipe 1 through an external infusion pump, and the contrast agent is sequentially delivered from the main pipe 1 to the interior of the connecting pipe 6, the delivery pipe 7, the filtrate pipe fitting 8 and the liquid outlet pipe 9 for discharge. The bottom end of the liquid outlet pipe 9 is connected to the port of the rubber thin pipe inside the patient's body, so that the contrast agent can be delivered into the patient's body. Using the infusion pump to automatically push the drug replaces the need for a dedicated person to manually inject the drug during the current imaging examination, thereby avoiding the radiation damage to the drug injection personnel. Moreover, after connecting the infusion pump to automatically push the drug through this adapter device, during the uterine and fallopian tube imaging examination, the injection flow rate, control switch can be set according to the patient's condition, and the infusion pump will automatically alarm when the pressure is too high, solving the problem of uneven manual injection flow rate, improving the safety of patients. The whole device is made of ABS material, acid and alkali resistant, high temperature resistant, high pressure resistant, sterilized by plasma, safe and economical, simple to operate, pollution-free, compatible with various size specifications, and effectively reducing the consumables.

[0031] When the device is delivering contrast fluid, the water flow pumped by the external infusion pump will impact the cross-cut of the silicone sealing layer 85, open the infusion channel, and carry out normal delivery of the contrast fluid. When the infusion pump stops delivering, the cross-opening of the silicone sealing layer 85 will automatically close due to the deformation recovery ability of the silicone, thereby blocking the channel between the liquid at the outlet tube 9 and the delivery tube 7, avoiding the phenomenon of liquid reflux in the outlet tube 9, reducing the contamination of the drug solution generated during uterine and fallopian tube angiography, and effectively improving the safety of medical equipment.

[0032] A stainless steel filter 83 is embedded in the inner ring surface of the first mounting ring 82, and a silicone sealing layer 85 is embedded in the inner ring surface of the second mounting ring 84. The filter pore size of the stainless steel filter 83 is 20um-30um, which can filter out the incompletely fused powder agglomerates in the contrast solution and the fine glass slag mixed into the solution during the opening process of the ampoule, thereby improving the contrast effect of the uterus and fallopian tube, and at the same time improving the safety of the contrast surgery.

[0033] By rotating the connecting sleeve 81 in the opposite direction, the connecting sleeve 81 can be removed from the bottom end of the delivery pipe 7, and the impurities filtered out from the top of the stainless steel filter screen 83 can be cleaned. In addition, by rotating the connecting sleeve 81 and the liquid outlet pipe 9 in the opposite direction, the filtrate pipe fitting 8 can be removed as a whole, which is convenient for disinfection and cleaning, thereby improving the convenience of cleaning the adapter.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
