Description

Technical Field

[0001] The invention belongs to the technical field of ICU nursing, and specifically refers to an infusion auxiliary device for ICU nursing. Background Art

[0002] ICU stands for Intensive Care Unit. Patients in ICU need a lot of infusion therapy every day. However, patients in ICU are usually unable to move normally, and nursing staff need to keep an eye on the progress of infusion, which is very inconvenient. In addition, in order to prevent the occurrence of pressure sores, patients need to be turned over regularly. When turning over, the patient's arm can easily cause the infusion tube to shake, and the infusion tube can drag the infusion bottle or infusion bag to shake, which can easily cause the infusion bottle or infusion bag to fall. When using the infusion tube for infusion, the infusion tube is generally too long, causing a long part of the infusion tube to hang in the air. If it cannot be effectively stored, it may affect the infusion and even cause secondary damage to the patient. Summary of the invention

The number of teeth of the third gear 67 is much larger than the number of teeth of the fourth gear 68.

[0043] A base 69 is provided at the bottom end of the telescopic infusion stand 1, and a universal wheel 23 is provided at the bottom of the base 69 to facilitate the movement of the device.

[0044] When in use, first adjust the height of the telescopic infusion stand 1 so that the suspension rod 7 and the hook 8 are lowered, the hand wheel 66 rotates to drive the third gear 67 to rotate, the third gear 67 drives the worm 60 to rotate through the fourth gear 68, the worm 60 rotates to drive the worm wheel 61 to rotate, the worm wheel 61 drives the adjusting gear 59 to rotate, and the adjusting gear 59 drives the adjusting rack 64 to move, so that the inner rod 56 slides downward along the outer tube 57, and the suspension rod 7 stops rotating the hand wheel 66 after it drops to a suitable height, and then the infusion bottle or infusion bag is fixed. Taking the infusion bottle as an example, turn the infusion bottle over and clamp the bottle cap of the infusion bottle at the bottom end of the clamping part 22 and push the infusion bottle along the clamping part 22 so that the transition between the bottle cap and the bottle body of the infusion bottle is clamped in the clamping part 22, and then continue to push the infusion bottle. The bottle drives the sliding sleeve 9 to slide along the suspension rod 7 through the end cover clamp 13, the tensioning sleeve 12 and the tensioning shaft 10. In the initial state, under the action of gravity, the upper wall of the sliding sleeve 9 fits with the upper wall of the suspension rod 7 and can slide freely to adjust the position. When the infusion bottle is aligned with the hook 8, stop pushing the infusion bottle, and then pull up the infusion bottle so that the bottom of the infusion bottle is hung on the hook 8. The bottle cap of the infusion bottle drives the tensioning sleeve 12 to compress the tensioning spring 11 and move up through the end cover clamp 13. The tensioning spring 11 pushes the sliding sleeve 9 to move up, and the bottom wall of the sliding sleeve 9 is close to the bottom wall of the suspension rod 7, so that the locking tooth 20 is stuck in the locking groove 19. The locking tooth 20 and the locking groove 19 limit the sliding sleeve 9 so that it cannot slide. The tensioning spring 11 makes the infusion bottle tensioned between the hook 8 and the end cover clamp 13. The bottle is tensioned and hung to fix the infusion bottle, so that when the infusion tube shakes, the infusion bottle will not shake with it, and then the bottle stopper puncture tool of the infusion set is inserted into the infusion bottle, and then the hand-cranked wheel 66 is reversed, thereby driving the inner rod 56 to slide upward along the outer tube 57, and the inner rod 56 drives the suspension rod 7 and the hook 8 as well as the suspended infusion bottle to move upward and reset, and then the hand-wearing piece 6 is worn on the patient's hand, and the rope 70 is pulled outward so that the rope 70 is completely pulled out, and then the middle part of the infusion tube is clamped into the clamping hole 41, and then the infusion tube is clamped into the guide sliding hole 37 through the oblique sliding hole 38. In the initial state, the slide seat 35 is arranged at the uppermost end of the screw rod 24, and the guide sliding hole 37 is aligned with the upper part of the circumferential side wall of the reel 25. At this time, the patient's hand is moved to a suitable position, Then the rope 70 is loosened, and the winding spring 31 drives the driven reel 26 to reverse and reset. The driven reel 26 drives the reel 25 to rotate through the driving gear 45, the concentric gear 1 46, the concentric gear 2 47, and the driven gear 48. The rotation of the reel 25 drives the infusion tube to be wound on the side wall of the reel 25. At the same time, the driven gear 48 drives the screw 24 to rotate synchronously through the first gear 49 and the second gear 50. The screw 24 drives the slide 35 to move downward, and the slide 35 drives the guide plate 36 and the infusion tube clamped on the guide plate 36 to move downward, so that the infusion tube is evenly wound from top to bottom on the outside of the reel 25 to avoid the infusion tubes from piling up and affecting the delivery of the drug solution. After the storage is completed, the injection needle is inserted into the patient's skin and fixed with tape for infusion. During the infusion process,When the patient's hand moves, the rope 70 will move with it. When the hand-worn part 6 is away from the storage box 4, the rope 70 pulls the driven reel 26 to rotate, and the driven reel 26 drives the reel 25 to rotate and unwind through the transmission gear set 1 33, so that the length of the infusion tube adapts to the distance of the patient's hand. When the hand-worn part 6 is close to the storage box 4, the coil spring 31 drives the driven reel 26 to rotate and rewind the rope 70 to ensure that the rope 70 is taut. The driven reel 26 drives the reel 25 to reverse through the transmission gear set 1 33 to rewind the infusion tube to avoid the infusion tube being too long.
