Description

Technical Field

[0001] The utility model relates to the technical field of infusion, in particular to an adjustable lifting device for maintaining an upper arm fully implantable infusion port. Background Art

[0002] An infusion port (PORT) is a closed infusion device that is completely implanted in the human body and can provide patients with long-term venous vascular access. An infusion port is a closed infusion device that is completely implanted in the human body, including a catheter portion with its tip located in the superior vena cava and an injection seat buried under the skin; it consists of three parts: a non-destructive needle (butterfly wing needle), a catheter inserted into the subclavian vein, and an injection seat (port body) buried under the skin and connected to the infusion needle. The injection seat connects the catheter inserted into the subclavian vein to form a long-term vascular access, playing a role similar to that of a port, so it is called an "infusion port". It establishes a central venous access and is suitable for cancer patients who undergo long-term chemotherapy, repeated blood draws, blood transfusions, and those who require long-term intravenous nutrition.

[0003] However, in the prior art, although the traditional lifting device can adjust the height, some patients' arms cannot be completely lifted vertically. Therefore, if only the height is adjusted but the angle cannot be adjusted during use, it will cause pain to the patient when placing his arm on the lifting board. At the same time, the lifting boards in the current lifting devices are mostly fixed. Therefore, if there are many patients and the height does not need to be changed during use, the traditional equipment still needs to change the position of the lifting board to lift the patients in multiple positions, resulting in a waste of time.

[0042] The upper surface of the support column 4 is fixedly connected with a fixed ball 11, and the outer wall of the fixed ball 11 is slidably connected with a sliding shell 12. The outer wall of the sliding shell 12 is fixedly connected with the outer wall of the support rod 9. The inner wall of the support column 4 is slidably connected with a slider 14. A sliding groove is provided in the wall of the support column 4, so that the slider 14 can slide in the sliding groove in the support column 4. The end of the slider 14 away from the support column 4 is rotatably connected with a fixed plate 13, and the outer wall of the fixed plate 13 is meshed with the outer wall of the gear 72.

A circular hole 34 is opened on the outer wall of the pillar 2, and the end of the limiting column 32 away from the handle 31 contacts the inner wall of the pillar 2.

[0043] Working principle:

[0044] When in use, the base 1 is placed on the ground to fix the lifting device, and the support column 4 is slid along the pillar 2. When the support column 4 slides to a suitable height, the fixing mechanism 3 is used to fix the position of the support column 4. At this time, the limiting column 32 in the fixing mechanism 3 is slid into the circular hole 34 on the pillar 2, and the limiting column 32 is fixed to the support column 4. At the same time, when the position of the support column 4 needs to be changed again, it is only necessary to pull the handle 31 outward to force the handle 31 to drive the limiting column 32 to slide out of the pillar 2. At the same time, a tension spring 33 is fixed between the handle 31 and the support column 4. Therefore, when the tension applied to the handle 31 is released, the elastic action of the tension spring 33 forces the handle 31 to drive the limiting column 32 to slide back into the pillar 2. When the support column 4 is slid, the resistance rod 6 located under the support column 4 will force the movement of the support column 4 to slow down, so that when the patient's arm is placed on the support plate 8, the movement amplitude of the support column 4 is reduced, thereby reducing the vibration of the arm.

[0045] After the support column 4 is changed to force the support plate 8 to the appropriate position, the support plate 8 can be slid to the desired position. At this time, the adjusting mechanism 7 can be adjusted. By rotating the turning handle 73 in the adjusting mechanism 7, the turning handle 73 can be forced to drive the gear 72 to rotate. When the gear 72 rotates, the toothed plate 15 meshing with the gear 72 and the fixed plate 13 can be forced to move relative to each other. The fixed plate 13 is connected to the support column 4 through the slider 14, and the toothed plate 15 is connected to the support rod 9. Therefore, when the gear 72 rotates, the height position of the support rod 9 can be changed. At the same time, because the position of the support rod 9 changes, the angle of the support plate 8 is changed synchronously. When it is adjusted to the desired position, the limiting rod 74 is inserted into the fixed shell 71 to fix the position of the turning handle 73, thereby fixing the position of the support rod 9, and because the slider 14 slides in the support column 4, and the bottom of the support rod 9 is connected to the fixed ball 11 through the sliding shell 12, the support rod 9 can be made to move in a circle along the support column 4 to adapt to patients in different positions.

[0046] When the height position is suitable for the patient's arm, the rotating mechanism 5 can be adjusted and the limit handle 51 in the rotating mechanism 5 can be taken out. At this time, the support plate 8 can be rotated along the rotating shaft 52. When it is adjusted to the required position, the limit handle 51 can be inserted through the support plate 8 into the limit plate 53, and a limit hole 54 is opened on the limit plate 53, so that the support plate 8 can be fixed on the limit plate 53.
