Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to implantable drug delivery devices. Background Technology

[0002] Implantable drug delivery devices, also known as infusion ports, are drug delivery devices implanted under the skin. Compared to peripherally inserted central venous catheters or central venous catheters, bacteria do not have a pathway to multiply at the catheter opening or migrate into the catheter interior, causing infection. They are safer and suitable for patients requiring long-term injections, such as those undergoing long-term chemotherapy or long-term intravenous infusions.

[0003] While existing implantable drug delivery devices can save medical staff time and facilitate patient treatment, the connectors of the connecting catheters cannot be cleaned in a timely manner, making it impossible to prevent bacterial infections caused by the connecting catheters. Furthermore, unused drug delivery devices cannot be neatly arranged during use, which can easily cause confusion when retrieving them and increase working time. Utility Model Content

[0024] Specifically, the disassembly and assembly mechanism 4 includes a limiting rod 41, a limiting groove 42, an elastic clamping plate 43, a limiting ring 44, and a closing mechanism 45. One side of the limiting rod 41 is fixedly connected to the first pipe 3. The side of the second pipe 5 near the limiting rod 41 has a limiting groove 42. The inner side of the limiting groove 42 is provided with an elastic clamping plate 43. The inner side of the second pipe 5 near the elastic clamping plate 43 is fixedly connected with a limiting ring 44. The inner side of the first pipe 3 is provided with a closing mechanism 45.

[0025] By adopting the above technical solution, during normal operation, the limiting rod 41 is locked in the limiting groove 42 and fixed by two elastic clamps 43. At this time, pipe 1 3, pipe 2 5 and connecting joint 6 are interconnected. The limiting rod 41 is fixed on pipe 1 3 and pipe 1 3 is connected to the main body 1 of the device. When it is necessary to disassemble the connecting joint 6, hold the connecting joint 6 and pipe 2 5 and rotate clockwise to make the limiting rod 41 disengage from the elastic clamps 43. Then pull the connecting joint 6 out along the limiting groove 42 for cleaning. The sealing mechanism 45 can block pipe 1 3 to prevent unused main body 1 from being contaminated.

[0026] Specifically, the closing mechanism 45 includes a slot 451, a cardboard 452, and a pull ring 453. The slot 451 is provided inside the pipe 3, the cardboard 452 is provided inside the slot 451, and the pull ring 453 is fixedly connected to the side of the cardboard 452 away from the slot 451.

[0027] By adopting the above technical solution, in the unused device, the cardboard 452 is inserted inside the slot 451, which can effectively isolate dust. When the device is activated, the cardboard 452 needs to be pulled out by pulling the pull ring 453.

[0028] Specifically, a sealing gasket 46 is provided on the side of pipe 3 near the cardboard 452.

[0029] By adopting the above technical solution, when the pipe 3 abuts against the limiting ring 44, the sealing gasket 46 can prevent the medicine from flowing out along the gap.

[0030] In this embodiment, the main body 1 of the device can contain the liquid medicine. The main body 1 is fixed inside the human body through the suture fixing hole 8. The connecting joint 6 can be connected to the catheter. During normal operation, the limiting rod 41 is stuck in the limiting groove 42 and is fixed by two elastic clamps 43. At this time, the first pipe 3, the second pipe 5 and the connecting joint 6 are interconnected. The limiting rod 41 is fixed on the first pipe 3, and the first pipe 3 is connected to the main body 1 of the device. When it is necessary to disassemble the connecting joint 6, hold the connecting joint 6 and the second pipe 5 and turn clockwise. The limit rod 41 is disengaged from the elastic clamp 43, and then the connecting joint 6 is pulled out along the limit groove 42 for cleaning. In unused devices, cardboard 452 is inserted inside the slot 451 to effectively isolate dust. When the device is activated, the pull ring 453 needs to be pulled to remove the cardboard 452. When the pipe 3 is pressed against the limit ring 44, the sealing gasket 46 can prevent the liquid from flowing out along the gap. By screwing the limit rod 41 into the elastic clamp 43, the connecting joint 6 can be fixed for easy subsequent cleaning.
