Description

Technical Field

[0001] The utility model relates to the technical field of medical trolleys, in particular to an auxiliary trolley. Background Art

[0002] With the continuous advancement of medical technology, patients pay more and more attention to early activities and walking during the recovery process after surgery, which helps promote physical recovery and reduce the occurrence of complications. However, for postoperative patients who need continuous infusion, how to maintain the stability and safety of infusion during walking has become a challenge.

[0003] The traditional way of postoperative infusion is to hang the infusion bottle above the bed or use an infusion stand to fix it. This method limits the patient's range of movement and is not conducive to early recovery. In order to solve this problem, a trolley that assists patients with postoperative infusion tubes to move around came into being.

[0004] This trolley was originally designed to help postoperative patients maintain stability and safety during infusion while walking. It is usually equipped with an infusion stand that can hold the infusion bottle and move on wheels. With the help of the trolley, patients can walk freely while ensuring that the infusion will not be affected.

[0005] For example, a Chinese utility model patent (CN218280026U) discloses a mobile cart, which solves the following problem: some cardiology patients need to stay in bed for a long time and need to be connected to monitors, injection pumps, infusion devices and other equipment, which means that they can only eat and go to the toilet in bed. If they want to leave the bed forcibly, they have to carry the above-mentioned equipment, which is very inconvenient.

[0006] The device includes a frame, wheels and a connecting device between the frame and wheels. The frame includes handrails on both sides and connecting rods connecting the handrails on both sides. The handrails include a vertical section, an inclined section one, a horizontal section and an inclined section two. The bottom and top of the handrails on both sides are connected by a plurality of connecting rods. The vertical section of the handrails on each side is provided with a plurality of supporting rods arranged at intervals from top to bottom. The supporting rod includes a horizontal section and rising sections at both ends of the horizontal section. The rising sections are tilted upward to play a supporting and limiting role. The utility model can provide convenience for critically ill patients to get up to use the toilet and walk, reduce the difficulty of getting up and the burden of carrying various instruments, and also provide convenience for patients to recover after surgery.

[0007] When using the above technology, it was found that the following technical problems exist in the prior art: the device lacks a suitable lifting structure, which makes the device unable to adapt to patients of different heights or body positions, increasing the risk of infusion tube falling off, and there is no suitable auxiliary rest structure, which may cause the patient to be unable to rest in the first time, causing physical discomfort and fatigue, and increasing discomfort. For this reason, we designed an auxiliary trolley to provide another technical solution to the above technical problems. Utility Model Content

[0046] A plurality of hooks are fixed on both sides of the bottom of the frame 1, and drainage devices such as drainage bags or flushing bags can be hung thereon.

[0047] The utility model provides an auxiliary trolley. The device can be adjusted according to the height and body position of the patient through the design of the lifting mechanism, ensuring that the infusion bottle is at a suitable height. Whether it is a tall patient or a short patient, they can find the infusion height that suits them best, avoiding the twisting or pulling of the infusion tube, and improving the comfort and safety of the infusion.

[0048] The device can provide patients with rest as soon as possible through the design of an auxiliary rest structure. This is especially important for patients who need to lie on the trolley for a long time, and can effectively reduce physical fatigue and discomfort.

[0049] The use process of an auxiliary trolley provided by the utility model is as follows: the user holds the handles on both sides of the top of the frame 1 with both hands, pushes the device to walk back and forth, which helps the patient recover. When the height of the hook 22 needs to be adjusted, the user energizes the second motor 14 to rotate, and the output end of the second motor 14 drives the first bevel gear 15 to rotate. Since one side of the first bevel gear 15 is meshed and connected with the second bevel gear 16, the rotation of the first bevel gear 15 drives the second bevel gear 16 to rotate, and then drives the second rotating rod 17 and the screw rod 18 to rotate. Since the outer side of the screw rod 18 is threadedly connected with a lifting sleeve 19, the rotation of the screw rod 18 drives the lifting sleeve 19 and the limit block 20 to slide and rise along the outer side of the limit rod 21. Since a hook 22 is fixed on one side of the lifting sleeve 19, the height of the hook 22 can be adjusted, which can meet the needs of different patients, improve the safety and comfort of infusion, expand the patient's range of activities, and facilitate medical treatment. The nursing operation of the nursing staff is of great significance for promoting the patient's recovery and improving the quality of medical care; when the patient needs to rest, the user energizes the hydraulic cylinder 12, and the output end of the hydraulic cylinder 12 drives the rack 11 to disengage the meshing connection with the gear 10, and then the user energizes the first motor 5 to rotate, thereby making the output end of the first motor 5 drive the worm 6 to rotate. Since the bottom of the worm 6 is meshed with the worm wheel 7, the rotation of the worm 6 drives the worm wheel 7 to rotate, and then drives the first rotating rod 8 and the rest seat 9 to rotate. After the rest seat 9 is adjusted to a suitable angle, the user energizes the hydraulic cylinder 12, so that the rack 11 resumes the meshing connection with the gear 10, ensuring the rotation stability of the rest seat 9, and the patient can sit on the top of the rest seat 9 to get a rest, which can ensure that the patient remains stable on the trolley to prevent accidents during movement or transportation. This provides additional safety protection for the patient and reduces potential safety risks.
