Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a PICC dressing change arm support device. Background Technology

[0002] PICC placement, also known as peripherally inserted central venous catheterization, involves inserting a catheter into a vein in the arm and reaching a large vein close to the heart. This avoids direct contact between chemotherapy drugs and the veins in the arm. Because of the fast blood flow in the large vein, the drugs can be quickly dispersed and diluted, preventing them from irritating the blood vessels.

[0003] According to Chinese Patent No. CN217660546U, a PICC dressing change auxiliary support and arm support device are disclosed. The PICC dressing change auxiliary support includes: a fixing component; a first connecting arm, one end of which is rotatably mounted on the fixing component. A first support plate is provided on the first connecting arm, and an elastic buckle is provided on one side of the first support plate for engaging the PICC tube. Although this device can provide effective support, it cannot be adjusted according to the arm length and thickness of different patients, thus requiring the purchase of support devices of different sizes. This not only increases costs but also requires medical staff to find the corresponding support devices, increasing the difficulty of the work and reducing work efficiency. Therefore, we propose a PICC dressing change arm support device to solve the above problems. Utility Model Content

A forearm support cylinder 10 is hinged to the forearm support cylinder 10. A second adjusting rod 11 is slidably connected inside the forearm support cylinder 10. A second through groove 12 is opened on the upper surface of the forearm support cylinder 10. A set of limiting blocks 13 are provided inside both the first through groove 8 and the second through groove 12. A locking block 14 is engaged inside each limiting block 13. The upper surfaces of two locking blocks 14 are jointly fixedly connected to the upper arm support plate 15, and the upper surfaces of the other two locking blocks 14 are jointly fixedly connected to the forearm support plate 16. The bottom of the first adjusting rod 7... Both the top surface of the boom support cylinder 6 and the bottom surface of the second adjusting rod 11 are provided with equidistant limiting holes 17. Both the bottom surface of the boom support cylinder 6 and the bottom surface of the forearm support cylinder 10 are provided with equidistant through holes 18. The interior of the limiting holes 17 and the interior of the through holes 18 are threaded together with limiting screws 19. The boom support cylinder 6, the first adjusting rod 7, the first through groove 8, the second hinge 9, the forearm support cylinder 10, the second adjusting rod 11, the second through groove 12, the boom support plate 15 and the forearm support plate 16 are provided. The position between the upper arm support plate 15 and the forearm support plate 16 can be adjusted according to the patient's own arm length. At the same time, the cooperation of the limiting block 13 and the locking block 14 allows the patient to change the size of the upper arm support plate 15 and the forearm support plate 16 according to the thickness of the arm. The first adjusting rod 7 and the second adjusting rod 11 can be fixed through the limiting hole 17, the through hole 18 and the limiting screw 19 to ensure the stability of the upper arm support plate 15 and the forearm support plate 16 after adjustment.

[0023] The inner walls of the boom support cylinder 6 and the forearm support cylinder 10 are slidably connected to limit plates 20. The left side of one limit plate 20 is fixedly connected to the right end of the first adjusting rod 7, and the left side of the other limit plate 20 is fixedly connected to the right end of the second adjusting rod 11.

The heat-insulating pad 21 ensures the temperature when the patient is in contact with the heat-insulating pad 21.

[0025] The working principle of this utility model is as follows:

[0026] During adjustment, first loosen the two limiting screws 19 to disassemble. Then, replace the corresponding upper arm support plate 15 and forearm support plate 16 according to the patient's arm width. Next, pull the upper arm support plate 15, which will cause the first adjusting rod 7 to slide inside the upper arm support cylinder 6. At the same time, it will cause the limiting block 13 to move. After sliding to a suitable distance and aligning the limiting hole 17 and the through hole 18, screw the limiting screw 19 into the through hole 18 and the limiting hole 17 to limit the first adjusting rod 7, thereby completing the adjustment according to the arm size. The forearm adjustment is the same as the above steps.
