Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a medical nursing trolley. Background Technology

[0002] In routine hospital nursing care, nursing carts are essential equipment for transporting medications, medical devices, and consumables, supporting nurses in various bedside treatment procedures from the nurses' station to the ward. In actual clinical practice, although nursing carts can be moved into the ward, when performing bedside nursing procedures such as intravenous infusions, dressing changes, or blood draws, nurses typically prefer to park the cart in a spacious area such as the nurses' station, aisle, or at the foot of the bed to improve efficiency, reduce noise from frequent cart movement, and avoid obstructing ward passageways. They then simply remove the tray containing the necessary items from the cart and carry the tray to the patient to perform the corresponding nursing care.

[0003] However, existing nursing trolleys and their accompanying trays are not adequately adapted to the aforementioned trolley-bed separation operation mode. In clinical practice, when nurses arrive at the bedside with the tray, due to the lack of a dedicated placement area, the tray often has to be temporarily placed on the bedside table, or even placed on the bed itself due to insufficient space on the bedside table. This irregular placement method is extremely unstable, easily causing the tray to tip over due to patient turning over or being touched, resulting in medication contamination or instruments slipping off. Furthermore, when the tray returns to the trolley for transport, it usually relies solely on gravity to remain in the groove, lacking a reliable limiting and fixing structure. When the trolley travels over bumpy surfaces such as elevators or small steps, the tray is prone to displacement or vibration, generating noise and affecting the safety of medical supplies. Therefore, there is an urgent need to improve existing technology and design a medical nursing device that can be securely locked to the trolley to ensure safe transport, and can also be easily attached to the bed rail after being detached from the trolley to adapt to clinical operations. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a medical care trolley to solve the problems of unstable placement of the tray at the bedside and unreliable fixation on the trolley.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medical care trolley includes a trolley body and multiple tray assemblies;

[0007] The top of the trolley body is provided with a tray placement area, which includes two baffles arranged opposite each other at the front and back, and multiple support crossbars connected between the two baffles;

[0008] The tray assembly is detachably placed within the tray placement area, and the tray assembly includes a box, hooks, locking components, and handles;

[0009] The hooks are provided on two opposite wide sides of the box body. The hooks are configured to engage with the support crossbar when the tray assembly is placed in the tray placement area, or to hang the tray assembly on an external support when the tray assembly is detached from the trolley body.

[0010] The locking components are disposed on two opposite narrow sides of the housing;

[0011] The handle is rotatably mounted at the top opening edge of the box body, and the handle has a flat state that is in contact with the opening edge of the box body and a non-flat state that is rotated and raised.

[0012] When the handle is in the flattened state, the handle cooperates with the locking component to lock the tray assembly within the tray placement area of ​​the trolley body; when the handle is in the non-flattened state, the locking component releases the locking of the tray assembly.

[0013] Furthermore, the handle has two rotating arms and a connecting crossbar connecting the two rotating arms, and the connecting crossbar is provided with a protruding ridge;

[0014] The locking assembly includes a lock box fixed to two opposite narrow sides of the housing, a lock cylinder disposed inside the lock box, and a return spring.

[0015] The top of the lock box is provided with a strip-shaped guide groove for the protruding ridge to be inserted; the lock box is provided with a lock cylinder slide cavity that communicates with the strip-shaped guide groove, and the lock cylinder is slidably disposed in the lock cylinder slide cavity;

[0016] One end of the lock cylinder is provided with an inclined block, and the inclined block has an inclined surface facing the strip guide groove;

[0017] The inclined block is normally located in the strip guide groove. When the protruding edge is inserted into or detached from the strip guide groove, the protruding edge cooperates with the inclined surface of the inclined block to drive the lock cylinder to move in the lock cylinder slide cavity.

[0018] Preferably, the lock cylinder further includes a connecting shaft and a locking pin fixedly connected to the inclined block; both the connecting shaft and the locking pin are round rods, and the diameter of the connecting shaft is smaller than the diameter of the locking pin;

[0019] The lock cylinder slide cavity is sequentially divided into a first cavity section, a second cavity section, and a third cavity section. The second cavity section and the third cavity section are shaft holes with diameters matching the diameters of the connecting shaft and the locking pin, respectively.

[0020] The inclined block is slidably disposed in the first cavity, the connecting shaft passes through the second cavity, and the locking pin is retractably disposed in the third cavity;

[0021] The reset spring is sleeved on the connecting shaft, with one end abutting against the inclined block and the other end abutting against the stepped surface formed between the first cavity segment and the second cavity segment.

[0022] Furthermore, the inner side of the enclosure plate is provided with a limiting groove that matches the shape of the lock box, and a locking hole is provided on the side wall of the limiting groove;

[0023] When the handle rotates from the non-flattened state to the flattened state, the protruding edge enters the strip guide groove and cooperates with the inclined surface of the inclined block, driving the inclined block to move deeper into the first cavity, thereby causing the locking pin to extend out of the third cavity and be inserted into the locking hole.

[0024] When the handle rotates from the flattened state to the non-flattened state, the protruding edge disengages from the strip guide groove. Under the action of the reset spring, the inclined block moves towards the strip guide groove, causing the locking pin to retract from the locking hole to the third cavity section to achieve unlocking.

[0025] Preferably, a connecting seat is provided at the opening edge of the upper end of the box body, and the two rotating arms of the handle are rotatably mounted on the connecting seat by means of a pin.

[0026] Furthermore, the trolley body has a multi-layer structure, including multiple drawer layers and a bottom open storage layer. Storage drawers are provided in the drawer layers, and a base plate is provided at the bottom of the open storage layer. One side of the base plate extends outward to form an auxiliary support platform.

[0027] Preferably, the trolley body further includes a trash can assembly, the bottom of which is placed on the auxiliary support platform; the side of the trash can assembly is provided with a positioning hook, and the trolley body is provided with a corresponding hanging rod, the positioning hook being connected to the hanging rod to limit the lateral displacement of the trash can assembly.

[0028] Furthermore, the trash can assembly includes a can body and a can lid, the can lid being rotatably hinged to the upper end of the can body via a connecting rod.

[0029] The core of this utility model's disclosed medical nursing trolley lies in the coordinated design of the tray assembly's hooks, handles, and locking components, enabling a single component to function adaptably in two scenarios. Compared to existing technologies, this utility model offers significant advantages: Firstly, the linkage between the handle's position and the locking component allows the tray to lock automatically and reliably upon being placed on the trolley, effectively resisting transport bumps and completely solving the problem of insecure fixation. Secondly, the dual-purpose design of the hooks allows the tray to be conveniently and stably attached to external supports such as bed rails after being detached from the trolley, providing nurses with a reliable bedside work platform and solving the problem of unstable bedside placement. The entire solution is intuitive to operate, requires no additional tools, and significantly improves the safety, standardization, and efficiency of nursing work. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] In traditional nursing trolley systems, the tray assembly can usually only be temporarily placed on the bedside table or bed after being detached from the trolley body. It lacks a dedicated and stable mounting structure, which poses a risk of tipping over. At the same time, the tray is placed on the trolley by gravity alone and lacks a reliable locking mechanism. It is prone to displacement during transportation and may affect the safety of medical supplies.

[0044] Based on this, and to improve the problems in related technologies, embodiments of this application provide a medical care trolley, such as... Figures 1 to 4As shown, the cart includes a trolley body 100 and multiple tray assemblies 200. The top of the trolley body 100 has a tray placement area 110, which includes two opposing side panels 111 and multiple support crossbars 112 connected between the two side panels 111. The tray assemblies 200 are detachably placed within the tray placement area 110. Each tray assembly 200 includes a housing 210, hooks 220, locking components 240, and a handle 230. The hooks 220 are located on two opposing wide sides of the housing 210 and are configured to engage with the support crossbars 112 when the tray assembly 200 is placed in the tray placement area 110, or to attach the tray assembly 200 to an external support when it is detached from the trolley body 100. The locking components 240 are located on two opposing narrow sides of the housing 210. The handle 230 is rotatably mounted on the top opening edge of the box body 210, and the handle 230 has a flat state that is flush with the opening edge of the box body 210 and a non-flat state that is rotated and tilted up. When the handle 230 is in the flat state, the handle 230 cooperates with the locking component 240 to lock the tray assembly 200 within the tray placement area 110 of the trolley body 100; when the handle 230 is in the non-flat state, the locking component 240 releases the locking of the tray assembly 200.

[0045] The tray placement area 110 of the trolley body 100 forms the basic support frame of the tray assembly 200, and the baffle 111 is used to limit the forward and backward displacement of the tray assembly 200. The tray assembly 200 is an independently usable unit. The box body 210 serves as a container, and the hooks 220 on its wide side have a dual function: when on the trolley, they are vertically engaged with the support crossbar 112, providing initial fixation; when bedside operation is required, the nurse can lift the entire tray assembly 200 by the handle 230 and use the same hook 220 to suspend it on an external support such as a bed rail, transforming it into a stable bedside worktable. The locking component 240 is the core component ensuring safe transport, and its status is linked to that of the handle 230. When the nurse presses the handle 230 down to a flat position where it is flush with the edge of the box 210, the locking mechanism is automatically triggered, rigidly fixing the tray to the trolley. When the tray needs to be retrieved, the handle 230 is simply pulled up to a raised, non-flat position, and the locking mechanism is automatically released.

[0046] The beneficial effects of this technical solution lie in its systematic resolution of two major clinical pain points: unstable tray placement on the trolley and lack of suitable bedside storage. The dual-purpose design of the hook 220 on the tray assembly 200 and the linkage mechanism between the handle 230 and the locking component 240 systematically address these issues. The hook 220 ensures a reliable and compliant temporary storage location for the tray after it is removed from the trolley, avoiding the safety risks associated with placing it on the bed or crowded bedside tables. The linkage locking mechanism ensures the tray can withstand bumps during transport, preventing accidental displacement or unlocking, greatly improving the safety of medical supply transport. The overall design is intuitive, requiring no additional steps or tools, significantly optimizing the efficiency and standardization of nursing procedures.

[0047] Alternatively, in some embodiments, such as Figure 3 As shown, the handle 230 has two rotating arms 231 and a connecting crossbar 232 connecting the two rotating arms 231. The connecting crossbar 232 has a protruding ridge 233. The locking assembly 240 includes a lock box 241 fixed to the narrow side of the housing 210, a lock cylinder 242 disposed in the lock box 241, and a return spring 243. The top of the lock box 241 has a strip-shaped guide groove 2411 for the protruding ridge 233 to be inserted; the lock box 241 has a lock cylinder slide cavity 2412 communicating with the strip-shaped guide groove 2411, and the lock cylinder 242 is slidably disposed in the lock cylinder slide cavity 2412. One end of the lock cylinder 242 has a wedge 2421, and the wedge 2421 has an inclined surface facing the strip-shaped guide groove 2411. The inclined block 2421 is normally located in the strip guide groove 2411. When the protruding ridge 233 is inserted into or removed from the strip guide groove 2411, the protruding ridge 233 contacts and presses against the inclined surface of the inclined block 2421, thereby driving the lock cylinder 242 to move horizontally within the lock cylinder slide cavity 2412.

[0048] This preferred embodiment details the mechanical linkage structure between the handle 230 and the locking assembly 240. When the handle 230 is pressed down to a flat position, the protruding ridge 233 slides along the inclined surface of the wedge block 2421. The inclined surface decomposes the vertical downward pressure, generating a force that pushes the lock cylinder 242 horizontally inward, thereby achieving locking. The strip guide groove 2411 precisely guides the movement path of the protruding ridge 233, ensuring the accuracy and repeatability of the action. The return spring 243 provides a constant return force, preparing for unlocking.

[0049] The beneficial effects of this design are that it converts rotational motion into linear motion using the principle of inclined planes. The structure is simple and efficient, and it possesses self-locking properties, effectively preventing the lock cylinder from accidentally springing back due to inertia under bumps and vibrations, thus ensuring absolute stability of the locked state. Furthermore, this linkage mechanism is completely integrated into daily operations; nurses can lock and unlock simply by pressing down or pulling the handle, eliminating the need to find additional latches or buttons, greatly improving operational convenience.

[0050] As a specific implementation scheme, the protruding ridge 233 can be designed as a transverse ridge of a certain length to increase the contact area and stability with the inclined block 2421. The inclined angle of the inclined block 2421 can preferably be between 45° and 60° to achieve a balance between effort saving and effective stroke. The lock box 241 can be precision machined from metal to ensure the dimensional accuracy and wear resistance of the strip guide groove 2411 and the lock cylinder slide cavity 2412.

[0051] Alternatively, in some embodiments, such as Figures 6 to 8 As shown, the lock cylinder 242 also includes a connecting shaft 2422 and a locking pin 2423 fixedly connected to the inclined block 2421; both the connecting shaft 2422 and the locking pin 2423 are round rods, and the diameter of the connecting shaft 2422 is smaller than the diameter of the locking pin 2423. The lock cylinder slide cavity 2412 is sequentially divided into a first cavity section, a second cavity section, and a third cavity section, with the second and third cavity sections having shaft holes whose diameters match the diameters of the connecting shaft 2422 and the locking pin 2423, respectively. The inclined block 2421 is slidably disposed in the first cavity section, the connecting shaft 2422 passes through the second cavity section, and the locking pin 2423 is telescopically disposed in the third cavity section. A return spring 243 is sleeved on the connecting shaft 2422, with one end abutting against the inclined block 2421 and the other end abutting against the stepped surface formed between the first and second cavity sections.

[0052] The lock cylinder 242 is a moving unit composed of a wedge block 2421, a slender connecting shaft 2422, and a thicker locking pin 2423. The lock cylinder slide cavity 2412 is designed with a stepped hole based on the dimensions of these three parts. The second cavity section serves as a precision guide hole for the connecting shaft 2422, strictly limiting its radial wobble and ensuring that the lock cylinder 242 can only move smoothly along the axis. The third cavity section fits tightly with the locking pin 2423, ensuring its precise extension direction. The return spring 243 is coaxially sleeved on the connecting shaft 2422, receiving uniform force and ensuring stable operation.

[0053] The beneficial effect of this design is that the guiding function of the connecting shaft 2422 eliminates the radial play of the lock cylinder 242 during movement, ensuring that the movement trajectory of the entire lock cylinder 242 is strictly linear after the wedge block 2421 is subjected to force. This allows the locking pin 2423 to accurately align with the target position each time it extends, avoiding jamming or wear caused by movement deviation. The larger diameter locking pin 2423 provides stronger shear resistance, ensuring locking strength.

[0054] Alternatively, in some embodiments, such as Figure 6 and Figure 7As shown, the inner side of the enclosure 111 is provided with a limiting groove 113 that matches the shape of the lock box 241, and a locking hole 114 is provided on the side wall of the limiting groove 113. When the handle 230 is rotated from the non-flat state to the flat state, the protrusion 233 enters the strip guide groove 2411 and cooperates with the inclined surface of the inclined block 2421, driving the inclined block 2421 to move deeper into the lock cylinder slide cavity 2412, thereby driving the locking pin 2423 to extend out of the lock box 241 and insert into the locking hole 114; when the handle 230 is rotated from the flat state to the non-flat state, the protrusion 233 disengages from the strip guide groove 2411, and under the action of the return spring 243, the inclined block 2421 moves in the opposite direction, driving the locking pin 2423 to retract from the locking hole 114 into the lock box 241 to achieve unlocking.

[0055] It is understandable that the limiting groove 113 is not only used to accommodate the lock box 241, but more importantly, it is used to perform preliminary lateral and longitudinal positioning of the tray assembly 200 after it is placed in place, ensuring that the lock box 241 fits against the inner wall of the limiting groove 113, thereby automatically aligning the axis of the locking hole 114 with the axis of the locking pin 2423. The depth of the locking hole 114 ensures that the locking pin 2423 can be fully inserted, forming a rigid limiting connection.

[0056] The beneficial effect of this scheme is that the limiting groove 113 provides the first-level positioning and anti-shaking constraint, while the locking pin 2423 inserted into the locking hole 114 provides the final-level mechanical locking that resists displacement and vibration in all directions.

[0057] Alternatively, in some embodiments, such as Figure 3 As shown, a connecting seat 211 is provided at the opening edge of the upper end of the box body 210, and the two rotating arms 231 of the handle 230 are rotatably mounted on the connecting seat 211 by means of a pin.

[0058] The connecting seat 211 is a protruding structure independent of the side wall of the box 210, and it usually has a shaft hole. A pin acts as a pivot, passing through the through hole at the end of the rotating arm 231 and the shaft hole of the connecting seat 211, forming a rotating hinge. By using the independent connecting seat 211, the stress point of the handle is transferred from the relatively weak side wall of the box 210 to a specially reinforced structure, improving the overall mechanical strength and durability. The pin-type hinge is a low-friction rotary joint, ensuring that the handle 230 remains smooth even after long-term frequent use, and will not become loose or stuck due to wear.

[0059] Alternatively, in some embodiments, such as Figure 1 and Figure 2 As shown, the trolley body 100 has a multi-layer structure, including multiple drawer layers and an open storage layer at the bottom. Storage drawers 300 are provided in the drawer layers, and a base plate is provided at the bottom of the open storage layer. One side of the base plate extends outward to form an auxiliary support platform 410.

[0060] The trolley's multi-layered structure enables functional zoning. Drawer shelves can be used to store items requiring dust protection, categorization, or a degree of privacy, such as medications, syringes, sterile dressings, and nursing documentation. The open storage layer at the bottom, without doors or lids, offers the most convenient access and is suitable for storing larger bottled liquids, boxes, or readily available public items. The auxiliary platform 410 is an additional platform extending horizontally from the bottom base plate, providing dedicated space for the subsequent trash can assembly 500 and also serving as a multi-functional extension countertop.

[0061] The beneficial effects of this solution are that the drawer layers enable refined management of items, complying with the "three checks and seven verifications" principle for medicines and consumables, and effectively reducing the time nurses spend searching for items. The bottom open storage layer provides flexible space for handling large quantities of supplies. The specially designed auxiliary support 410 provides a separate placement area for the trash can assembly, away from internal cleaning items, in accordance with infection control zoning principles.

[0062] As one specific implementation, the storage drawer 300 can use damped silent slides to ensure smooth and quiet sliding. A transparent label bag can be provided on the front of the drawer for easy identification of the contents. The surface of the auxiliary support 410 can be treated with an anti-slip finish, such as by attaching an anti-slip mat or processing an anti-slip texture. As an alternative embodiment, the auxiliary support 410 can also be designed to be flip-up and retractable, reducing the width of the trolley when not in use, making it easier to pass through narrow ward doors and corridors.

[0063] Alternatively, in some embodiments, such as Figure 2 As shown, the trolley body 100 also includes a trash can assembly 500, the bottom of which is placed on an auxiliary support 410; a positioning hook 510 is provided on the side of the trash can assembly 500, and a corresponding hanging rod is provided on the trolley body 100. The positioning hook 510 is connected to the hanging rod to limit the lateral displacement of the trash can assembly 500.

[0064] The positioning hook 510 is typically a J-shaped or L-shaped metal hook, installed on the side of the trash can. The matching hanging rod is a round rod horizontally fixed to the frame (such as a column) of the trolley body 100. In use, first place the bottom of the trash can on the auxiliary support 410, and then hang the positioning hook 510 on its side onto the matching hanging rod to complete the fixation.

[0065] The beneficial effect of this design is that it provides a quick and reliable anti-tipping securing solution for medical waste bins. The auxiliary support 410 bears the vertical load, while the side hook-and-bar mechanism is specifically designed to resist the horizontal inertial forces generated when the cart starts, stops, turns, and bumps.

[0066] Optionally, in some embodiments, the trash can assembly 500 includes a body and a lid 520, the lid 520 being rotatably hinged to the upper end of the body via a link 530.

[0067] The core of this design lies in the linkage 530, which connects the lid 520 to the container body. When it is necessary to open the lid to dispose of waste, the operator (such as a nurse) simply lifts the lid 520, and the linkage 530 causes the lid 520 to rotate around the hinge point, lifting it upwards or to the side and suspending it. During this process, the lid 520 remains connected to the container body via the linkage 530, requiring no removal from the container body or placement on the ground, bed, or other potentially contaminated surfaces.

[0068] In summary, the working principle of this medical nursing trolley forms an efficient and smooth operational closed loop around the state transition of the tray assembly 200. At the start of the operation, the nurse places the tray assembly 200, equipped with the necessary nursing supplies, into the tray placement area 110 on the top of the trolley. At this time, the tray assembly 200 is naturally hooked onto the support crossbar 112 via the hooks 220 on its side. Subsequently, the nurse presses down the handle 230 until it is flat against the edge of the box 210. This action drives the locking cylinder 242 in the locking assembly 240 through the protrusion 233 on the handle 230, ultimately causing the locking pin 2423 to extend and securely insert into the locking hole 114 inside the baffle plate 111, thereby achieving rigid locking of the tray on the trolley and ensuring safety and stability during transport. When the trolley arrives at the ward and bedside procedures are needed, the nurse simply pulls up the handle 230 to the tilted position, releasing the lock. The entire tray assembly 200 can then be easily removed by the handle 230 and securely hung on the bed rail using the same hook 220, instantly creating a reliable and highly adaptable temporary workbench for clinical workflow. Simultaneously, the multi-layered storage structure of the trolley body 100 provides continuous material support for operations, while the trash can assembly 500, fixed to the auxiliary support 410 by the positioning hook 510, can be easily removed and placed beside the bed, enabling immediate and standardized collection of medical waste. The entire workflow is seamless, integrating multiple functions such as stable transportation, convenient access, bedside mounting, material support, and waste management into one efficient mobile nursing workstation, significantly improving the efficiency, safety, and standardization of clinical nursing work.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
