[0002] It is a closed infusion device that is completely implanted in the human body. It consists of a port body buried under the skin and a catheter inserted into the vein. It provides a safe infusion channel for patients undergoing cancer chemotherapy and avoids the stimulation of peripheral blood vessels by chemotherapy drugs. The fully implantable infusion port in the arm is referred to as the arm port. The port body is buried on the inner side of the upper arm, but when in use, a nurse needs to insert a special non-destructive needle into the port body to complete catheter function evaluation, infusion, blood transfusion and other treatments. The infusion port performs operations such as flushing and sealing the tube through puncture.

When the lying plate 3 is rotated, the upper rotating arm 41 will push the first connecting column 42 due to the different rotation radius from the lying plate 3. Since the first connecting column 42 moves in the sliding groove 8 in the fixed block 6, the first connecting column 42 will move toward the second connecting column 47 under the push of the upper rotating arm 41. Similarly, when the leg lifting plate 5 moves, it will drive the lower rotating arm 48 to rotate, and due to the extrusion of the first connecting column 42 and the second connecting column 47, the first lifting plate 43 and the second lifting plate 46 will lift the armrest 44 under the extrusion.

At this time, the pressing plate 456 is pressed to press down the end of the first lever 457 close to the pressing plate 456. At this time, the other end of the first lever 457 is tilted, and at the same time, the tilted end of the first lever 457 lifts the second lever 458. After the end of the second lever 458 close to the first lever 457 is tilted, the other end will drop. At this time, the fixing plate 459 will drive the rubber ring 4510 to press down until the rubber ring 4510 fits the patient's skin and reveals the outline of the infusion port.

[0020] The inner surface of the support frame 2 is rotatably connected to the outer surface of the lying board 3, and the inner surface of the support frame 2 is rotatably connected to the outer surface of the leg-lifting board 5. A sliding groove 8 is provided in the wall of the lying board 3. A fixed block 6 is fixedly connected to the outer surface of the lying board 3, and a movable groove 7 is provided in the wall of the fixed block 6. The outer surface of the lying board 3 is rotatably connected to the inner surface of the upper rotating arm 41, and the outer surface of the leg-lifting board 5 is rotatably connected to the inner surface of the lower rotating arm 48. The outer surfaces of the first connecting column 42 and the second connecting column 47 are both slidably connected to the inner surface of the fixed block 6. The rising armrest 44 can guide the patient's upper arm to be placed at a suitable angle, providing a support plane for maintenance operations, so as to reduce the workload caused by repeated guidance during nurse operations.

[0021] The outer surface of the sliding plate 451 is slidably connected to the inner surface of the armrest 44, the upper surface of the bottom of the magnetic base 452 contacts the lower surface of the magnetic block 453, the inner surface of the first lever 457 is rotationally connected to the outer surface of the sliding block 455, the inner surface of the second lever 458 is rotationally connected to the outer surface of the sliding block 455, the outer surface of the fixed plate 459 is slidably connected to the inner surface of the sliding block 455, the patient's arm is placed in front of the armrest 44, the sliding plate 451 is moved so that the elastic ring 454 reaches the vicinity of the infusion port, the magnetic block 453 is pushed into the sliding plate 451, and the magnetic block 453 is placed in the magnetic base 452 for position fixation, and the sliding block 455 is moved until the rubber ring 4510 reaches above the infusion port.

[0022] Working principle:

[0023] A positioning device 45 is set, and the patient's arm is placed in front of the armrest 44. After the sliding plate 451 is moved so that the elastic ring 454 reaches the vicinity of the infusion port, the magnetic block 453 is pushed into the sliding plate 451, and the magnetic block 453 is placed in the magnetic base 452 for position fixation, and the sliding block 455 is moved until the rubber ring 4510 reaches above the infusion port. At this time, the pressing plate 456 is pressed to press down the end of the first lever 457 close to the pressing plate 456. At this time, the other end of the first lever 457 is tilted, and at the same time, the tilted end of the first lever 457 lifts the second lever 458. After the end of the second lever 458 close to the first lever 457 is tilted, the other end will drop. At this time, the fixing plate 459 will drive the rubber ring 4510 to press down until the rubber ring 4510 fits the patient's skin and the outline of the infusion port is revealed, so as to facilitate medical staff to find the location of the infusion port.

[0024] When in use, a lifting device 4 is provided. For different maintenance needs of patients, corresponding maintenance postures of the patients need to be selected. The lying board 3 and the leg-lifting board 5 on the support frame 2 can be moved selectively to form a reclining chair shape with the upper surface of the support seat 1. The support seat 1, the lying board 3 and the leg-lifting board 5 can also be selected to form a seat shape. When the reclining chair shape is changed to the seat shape, the upper rotating arm 41 leaves the movable groove 7 of the fixed block 6. At the same time, the upper rotating arm 41 will push the first connecting column 42 due to the different rotation radius from the lying board 3. Since the first connecting column 42 is in the sliding groove 8 in the fixed block 6 The first connecting column 42 moves inward, so the first connecting column 42 will move toward the second connecting column 47 under the push of the upper rotating arm 41. Similarly, when the leg lifting board 5 moves, it will drive the lower rotating arm 48 to rotate, and at the same time push the second connecting column 47 close to the first connecting column 42. Because the rotational connection position of the first lifting plate 43 and the second lifting plate 46 and the armrest 44 is fixed, and due to the squeezing of the first connecting column 42 and the second connecting column 47, the first lifting plate 43 and the second lifting plate 46 will lift the armrest 44 under the squeezing action, so that the height of the armrest 44 can adapt to patients with different postures.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
