[0001] The present invention relates to the technical field of medical devices, and in particular to an electric nursing treatment cart. Background Art

[0002] Nursing staff account for a large proportion among hospital technical staff, are highly professional, cover a wide range of aspects, and have a heavy workload. Usually, nursing staff carry out nursing work in relatively crowded wards. Therefore, corresponding nursing treatment carts are usually equipped, with corresponding drugs and nursing tools arranged on the nursing treatment carts to reduce the number of times nursing staff need to fetch items back and forth and relieve the work burden of nursing staff. Therefore, nursing treatment carts are essential medical devices in the daily work of nursing staff. In the prior art, the improvement of nursing treatment carts mainly focuses on the reasonable layout of the storage space of the nursing cart, in the hope of obtaining a nursing treatment cart that can accommodate more drugs and nursing tools and has a more scientific layout of drugs and nursing tools. For example, the invention patent with the publication number CN211512459U, a drug-sorting mobile nursing cart, is a technical solution for improving the spatial layout of the nursing cart. However, as the nursing treatment cart can accommodate more and more drugs and nursing tools, the load of the nursing treatment cart will also become heavier and heavier. Nursing staff pushing these medical treatment carts filled with drugs and nursing tools consume more and more physical strength, which instead increases the work burden of nursing staff from another aspect. Therefore, an electric nursing treatment cart that can turn flexibly in a crowded ward is an increasingly urgent need for front-line nursing staff. Summary of the Invention

[0014] To electrify the nursing treatment cart to reduce the work burden of nursing staff, it is necessary to consider how to solve the turning problem of the nursing treatment cart to meet the need of flexible turning in a crowded ward; for this purpose, this embodiment provides a technical solution for an electric nursing treatment cart.

[0015] Embodiment 1: Refer to Figures 1-5 , an electric nursing treatment cart, comprising a frame 1, a steerable Segway 2, and a connecting mechanism 3 connecting the rear end of the frame 1 and the middle part of the Segway 2; universal wheels 11 are provided at the four corners of the bottom surface of the frame 1; a rotating plate 12 extending backward is provided at the midpoint position of the rear end of the frame 1; a vertical rotating hole 121 is provided on the rotating plate 12; the connecting mechanism 3 includes an acting rod 31, a rotating rod 32, a vertical rod 33, and a hinge shaft 34; the acting rod 31 is horizontally arranged, and the two ends are respectively horizontally hinged to the outer shells of the universal wheels 11 at the rear end of the frame 1; the hinged positions of the two ends of the acting rod 31 with the outer shells of the universal wheels 11 and the rotating connection positions of the universal wheels 11 and the frame 1 are arranged in a parallelogram; the acting rod 31, the two universal wheels 11, and the frame 1 form a parallelogram linkage mechanism, and the lateral movement of the acting rod 31 can be converted into the synchronous deflection of the two universal wheels 11. Refer to Figure 5; The rear end of the rotating rod 32 is fixedly connected to the fixed part in the middle of the self-balancing vehicle 2; a horizontal long hole 322 in the same axial direction as the rotating rod 32 is provided at the front end of the rotating rod 32; a hinge hole 311 matching the horizontal long hole 322 is provided at the midpoint of the acting rod 31; a hinge shaft 34 passes through the horizontal long hole 322 and the hinge hole 311 to establish the connection relationship between the rotating rod 32 and the acting rod 31; the lower end of the vertical rod 33 is fixedly connected to the middle part of the rotating rod 32; the vertical rod 33 is in rotational cooperation with the rotating hole 121; changes will occur on the left and right sides of the self-balancing vehicle 2, that is, the steering of the self-balancing vehicle 2; the steering of the self-balancing vehicle 2 is prior art, and for example, the steering control method of a two-wheeled self-balancing vehicle in the invention patent with the publication number CN103770872B has been disclosed in detail, and will not be elaborated herein; after steering, the self-balancing vehicle 2 will necessarily cause a certain deflection of the rotating rod 32; see Figure 5 , when the self-balancing vehicle 2 turns to the right, it will cause the left wheel of the self-balancing vehicle 2 to exceed the right wheel of the self-balancing vehicle 2, which causes the rotating rod 32 to deflect to the right around the vertical rod 33; at the same time, the front end of the rotating rod 32 will force the entire acting rod 31 to move horizontally to the right; as for the front-back longitudinal movement of the acting rod 31, it can be adapted by the horizontal long hole 322 and the hinge shaft 34; in this way, the universal wheel 11 at the rear end of the vehicle frame 1 will turn to the left; then the universal wheel 11 at the front end of the vehicle frame 1 will automatically adapt to the steering as the entire nursing treatment vehicle moves, and the electric nursing treatment vehicle driven by the self-balancing vehicle 2 will turn to the left.

[0016] In this way, the nursing treatment vehicle can be changed from being manually pushed to being electrically driven by the self-balancing vehicle 2 and can be steered, which is suitable for use in crowded wards and reduces the work burden of nursing staff.

[0017] A grip 331 perpendicular to the rotating rod 32 is provided at the upper end of the vertical rod 33 for a nursing staff to hold when driving the electric nursing treatment vehicle to maintain body balance.

[0018] A brake 332 is also provided at the upper end of the vertical rod 33; a brake is provided inside the universal wheel 11 and is connected to the brake 332 through a brake cable 3321; the brake 332 is used for parking; at the upper end of the vertical rod 33, at a position very convenient for a nursing staff to operate with both hands, it is convenient for the nursing staff to control the brake inside the universal wheel 11 in time through the brake 332 for parking.

[0019] A U-shaped clamp 321 is provided at the front end of the rotating rod 32; the acting rod 31 passes through the middle of the U-shaped clamp 321; the horizontal long hole 322 is provided on both sides of the U-shaped clamp 321; the U-shaped clamp 321 not only plays the role of connecting the acting rod 31, but also plays the role of limiting the extreme deflection angle of the rotating rod 32; when the rotating rod 32 deflects to the extreme position, the inner end of the U-shaped clamp 321 will interfere with the acting rod 31 to prevent the rotating rod 32 from deflecting excessively and causing an accident due to the nursing treatment vehicle turning too sharply.

[0020] The frame 1 includes a vertical storage compartment 13 at the front end and a multi-layer storage compartment 141 at the rear end; the multi-layer storage compartment 141 includes several layers of storage compartments 141; the multi-layer storage compartment 141 and the vertical storage compartment 13 can be used to simply store medicines and nursing tools; for example, the multi-layer storage compartment 141 is used to store medicines and nursing tools; liquids for intravenous injection are relatively heavy and can be placed in the storage compartment 141 on the bottom layer; nursing tools are less heavy and can be placed in the middle storage compartment 141; solid medicines or smaller nursing tools that are frequently used are placed in the storage compartment 141 on a higher layer; and the vertical storage compartment 13 can be used to hold medical waste.

[0021] There are several rotating plates 12, which are respectively arranged at the center position of the rear end of the storage compartment 141; the middle part of the vertical rod 33 passes through the rotating hole 121 on each rotating plate 12; these rotating holes 121 can not only cooperate with the vertical rod 33 to form a rotating pair, but also provide horizontal limit for the setting of the vertical rod 33; when the nursing staff supports the handle 331, the deflection and deformation of the vertical rod 33 are avoided.

[0022] A fence 15 is provided on the top of the frame 1; medicines or nursing tools can also be temporarily stored on the top of the frame 1; these medicines or nursing tools generally need to be used immediately; the purpose of placing them on the top of the frame 1 is to facilitate access; for example, liquid that needs intravenous injection immediately can be directly placed on the top of the frame 1 after mixing, and the room number and bed number can be annotated on the bottle label of the liquid; for example, a moxibustion device that needs to be used immediately can also be placed on the top of the frame 1 to avoid the electric nursing treatment vehicle arriving in a crowded ward and being unable to be taken out from the inside of the frame 1; and the fence 15 is to avoid medicines or nursing tools from sliding off the top of the frame 1 during transportation; the fence 15 is mainly arranged on the multi-layer storage compartment 141.

[0023] Working principle of this embodiment: The power for the electric nursing treatment vehicle to move forward, backward and turn comes from the balance vehicle 2, which can reduce the workload of nursing staff in transporting medicines and nursing tools in the ward; according to the steering operation of the balance vehicle 2, the present invention can change the deflection direction of the universal wheel 11 at the rear end of the frame 1, thereby realizing the steering of the entire electric nursing vehicle; the steering process of the present invention is as follows: ① The nursing staff operates the balance vehicle 2 in the reverse direction according to the desired direction; ② The turning of the balancing vehicle 2 causes the rotating rod 32 to deflect accordingly around the vertical rod 33; ③ The deflection of the rotating rod 32 acts on the action rod 31 through the front end of the rotating rod 32, so that the action rod 31 drives the universal wheel 11 at the rear end of the frame 1 to deflect in the opposite direction to the operation direction of the balancing vehicle 2; ④ Operate the balance vehicle 2 to move forward stably, and the electric nursing treatment vehicle moves with the help of the state of the wheels of the balance vehicle 2 and the state of the universal wheels 11 at the rear end of the frame 1; ⑤The universal wheel 11 at the front end of the vehicle frame 1 deflects following the movement, and the electric nursing treatment vehicle realizes steering. For the forward and backward movement of this new embodiment, after the nursing staff adjusts the deflection state of the universal wheel 11 at the rear end of the vehicle frame 1 and the state of the wheels of the balance vehicle 2 to a straight-line walking state, then drive.

[0024] Embodiment 2: The technical solution of Embodiment 2 is basically the same as that of Embodiment 1, and the same parts will not be repeated. The differences are as follows: The vehicle frame 1 includes a side opening door and an internal compartment; the side opening door is arranged on one side of the vehicle frame 1 and is slidably connected to the vehicle frame 1 at the bottom; the internal compartments are horizontally evenly distributed in the internal space; similar to the invention patent of a mobile nursing cart for medicine distribution with the publication number CN211512459U, the side opening door of the vehicle frame 1 in this embodiment is a sliding door structure; this side opening door structure reduces the occupation in the width direction of the electric nursing treatment vehicle, so that in a crowded ward, as long as there is enough space in the length direction of the electric nursing treatment vehicle, the side opening door can be opened to take the drugs or nursing tools displayed on the internal compartment; and the internal compartments can also reasonably arrange the drugs or nursing tools according to the size of their respective accommodation spaces, making the storage of drugs or nursing tools on the nursing cart more reasonable and scientific.

[0025] There are several rotating plates 12, which are vertically evenly distributed on the rear end face of the vehicle frame 1; the middle part of the vertical rod 33 passes through the rotating holes 121 on each rotating plate 12; the rotating plates 12 and the rotating holes 121 on the rotating plates 12 are used to establish a stable connection between this type of vehicle frame 1 and the connecting mechanism 3.

[0026] Embodiment 3: The technical solution of Embodiment 3 is basically the same as that of Embodiment 2, and the same parts will not be repeated. The differences are as follows: The outer end of the side opening door is hinged to the vehicle frame 1; this type of side opening door structure is a conventional side door opening structure in the prior art; compared with Embodiment 2, after this side opening door structure is fully opened, the drugs or nursing tools in the internal compartment can be seen at a glance without visual dead angles, which is extremely convenient for the nursing staff to overall control the drugs or nursing tools in the vehicle frame 1.
