Description

Technical Field

[0001] The invention relates to the technical field of intensive care, in particular to a dressing changing device and a dressing changing method for an ICU intensive care unit. Background Art

[0002] In the ICU, dressing change is a crucial link, which involves the stabilization and recovery of the patient's condition. Infusion agents are a key part of the dressing change process, including saline, glucose solution, antibiotic solution, etc.

[0003] The patent with application number CN202210909905.5 discloses a medical tower crane for ICU, including a beam frame, two carriers are arranged at the bottom of the beam frame along the direction of movement, and a holding tube for accommodating infusion bottles is arranged on the side wall of any of the two carriers. The inside of the holding tube is distributed with several cavities in a circular shape. After each infusion bottle is placed in the cavity, its bottle mouth passes through the bottom of the cavity and is exposed outside the cavity. The present invention realizes automated infusion and fluid exchange, avoids manual operation, and thus greatly reduces the workload of medical staff.

[0004] Existing ICU dressing change devices often rely on multiple or highly complex drive mechanisms to execute the dressing change process, which not only significantly increases the overall complexity and manufacturing cost of the equipment, but also the integration of a large number of mechanical components and drive devices leads to a large mass of the dressing change system, which brings many inconveniences to the lifting, relocation and daily operation of the equipment. In addition, these traditional devices often lack a built-in drug oscillation mechanism and cannot effectively prevent the precipitation of drugs in the infusion bag due to long-term standing, which may affect the uniform distribution of the drug and the expected effect of infusion therapy, posing a potential risk to the patient's treatment effect.

[0005] In view of this, we propose a dressing changing device and a dressing changing method for an ICU intensive care unit. Summary of the invention

[0016] On the other hand, the present invention also provides a dressing change method for an ICU intensive care unit, using the above-mentioned dressing change device for an ICU intensive care unit, comprising the following steps: S1. First, the medical staff hangs several prepared infusion bags under several hooks in the suspension device in sequence, and fixes the infusion plug inside the fixing clip; S2. Then, the telescopic rod of the electric push rod is controlled to move upward, thereby driving the fixing clamp to move upward as a whole, and then the infusion plug is inserted into the infusion bag above it. The medical staff evacuates the air in the infusion tube and inserts the infusion needle into the patient; S3. Afterwards, when the medicine in the infusion bag is delivered, the telescopic rod of the electric push rod is controlled to move downward, and the infusion plug moves away from the interior of the infusion bag together with the downwardly moving fixing clip; S4.

Subsequently, when the liquids in the several infusion bags have been transported and shut off, the medical staff can remove the infusion bags from the several hooks.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The dressing changing device and dressing changing method used in the ICU intensive care unit can pull out the infusion plug from the old infusion bag by controlling the telescopic rod of the electric push rod to move up and down, and then drive the suspension device to rotate, and move the new infusion bag above the infusion plug. When the telescopic rod continues to move upward, the liquid plug is immediately inserted into the new infusion bag, thereby reducing the investment in additional driving equipment while completing the patient's dressing change work, greatly reducing the weight of the overall dressing changing system, and reducing the burden on the hoisting structure.

[0018] 2. In the dressing changing device and dressing changing method used in the ICU intensive care unit, when the outer sleeve rotates outside the fixed cylinder, the docking gear contacts the outer sleeve ring gear and rotates, driving the hook to swing back and forth, thereby driving the medicine in the infusion bag to oscillate, thereby preventing the medicine from settling at the bottom of the bag after being left still for a long time, and making the components mixed more evenly, thereby ensuring the effect and safety of the infusion.

[0031] Furthermore, the infusion bag 510 is used to store therapeutic drugs, and the cylindrical plug 511 cooperates with the structure in the rotating device 300 to ensure the stability of the bottom end of the infusion bag 510. After the infusion plug 520 is inserted into the interior of the infusion bag 510, the therapeutic drugs are introduced into the interior of the infusion tube, and cooperate with the drip bucket 530 and the flow regulator 540 to ensure that the drugs are smoothly delivered into the patient's body.

The inner cylinder wall of the rotating cylinder 310 is provided with a cylinder wall convex groove 311 for providing a moving range for the outer convex rod 270. Specifically, the size of the convex groove 311 on the cylinder wall is matched with the size of the end of the outer convex rod 270, and the rotating disk 320 is clamped and fixed on the outer wall of the rotating cylinder 310.

At this time, the telescopic rod that continues to move downward drives the outer convex rod 270 to move in the convex groove 311 of the cylinder wall, thereby driving the rotating cylinder 310 and the outer sleeve long cylinder 410 to rotate; S5, after the outer convex rod 270 moves to the bottom groove wall of the barrel wall convex groove 311, the telescopic rod of the electric push rod 260 is controlled to move upward again, and the rotating barrel 310 is driven to rotate and move the new infusion bag 510 to the top of the infusion plug 520; S6. Afterwards, as the outer convex rod 270 continues to move upward in the vertical groove of the barrel wall convex groove 311, the infusion plug 520 is re-inserted into the upper infusion bag 510 along with the fixing clip 280, and the infusion treatment for the patient continues through the infusion system 500; S7, when the rotating cylinder 310 rotates outside the fixed cylinder 210, the docking gear 431 in the swinging part 430 contacts the outer ring gear 230 and rotates, thereby driving the lever 432 to rotate; S8, after the lever 432 rotates, the position where the protruding rod at the end thereof contacts the inner wall of the movable frame 433 is continuously changed, thereby driving the movable frame 433 to reciprocate, and then driving the limit slide bar 434 and the hook 435 to reciprocate, thereby driving the infusion bag 510 to swing continuously; S9. Subsequently, when the liquids in the infusion bags 510 are all transported and closed, the medical staff can remove the infusion bags 510 from the hooks 435.
