Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a treatment vehicle for clinical use. Background Technology

[0002] Clinical treatment carts are typically used for transporting and storing medications, dressings, injection supplies, and other therapeutic items. To facilitate movement of the carts between wards, treatment rooms, and nursing stations, they are usually equipped with casters, some of which are swivel casters capable of free steering, improving the cart's ability to move and turn in confined spaces.

[0003] After the treatment cart is moved to its designated position, medical staff need to open storage drawers, retrieve or store treatment supplies, or operate the functional areas on the side of the cart. During these processes, the pulling or pushing forces applied by the medical staff can easily be transmitted through the cart to the casters, causing the cart to slip or deflect. This is especially true on slippery surfaces, when drawers contain heavy items, or when drawers offer significant resistance when opening or closing. Medical staff sometimes need to use one hand to support the cart while using the other to retrieve or store items, affecting the convenience and stability of the operation.

[0004] Existing treatment carts typically rely on the braking mechanisms of their casters to restrict movement. However, the braking positions of each caster are low and dispersed, often requiring individual operation, which is inconvenient. Furthermore, the cart may still rotate or slip slightly if some casters are not effectively braked. Additionally, if the waste disposal area is not closed promptly after use, the waste collection space may remain open to the outside, hindering the cleanliness of the surrounding environment and storage area. Therefore, it is necessary to improve the supporting anti-slip structure of the treatment cart during parking and use, while also incorporating the automatic closing function of the waste disposal area. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a treatment cart for clinical use, which enables the treatment cart to switch between a moving state and a supported state, and improves the stability of the treatment cart relative to the ground in the supported state.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A treatment cart for clinical use has a push handle attached to one side of its body. A storage drawer can be pulled out and housed within the body, which is supported by a base with casters attached to the bottom surface of the base. An anti-slip assembly is provided on the side of the body opposite the push handle. The support component of the anti-slip assembly can be raised and lowered along the height of the body, a limiting component is fixed relative to the body, and a locking component moves with the support component and can be disengaged from the limiting component.

[0007] The lower end of the support component is connected to an anti-slip pad, and the base forms a clearance groove corresponding to the downward movement path of the support component. The locking component and the limiting component engage to keep the support component in a stored position where the anti-slip pad is separated from the ground, or in a supported position where the support component moves downward and the anti-slip pad presses against the ground through the clearance groove.

[0008] Furthermore, the limiting member has a first limiting plate and a second limiting plate spaced apart along the lifting direction of the support member, with the engaging position of the first limiting plate higher than that of the second limiting plate. When the locking member engages with the first limiting plate, the support member remains in the retracted position; when the locking member engages with the second limiting plate, the support member remains in the supporting position.

[0009] Furthermore, the anti-slip pad is elastic. When the locking element engages with the second limiting plate, the anti-slip pad is compressed and undergoes elastic deformation, pressing against the ground in an interference fit.

[0010] Furthermore, the guide rail extends along the height direction of the housing and is fixed relative to the housing. The rollers are rotatably connected to the support and roll in cooperation with the guide rail. The guide rail restricts the support from deviating from the lifting direction and guides the support to move up and down.

[0011] Furthermore, the locking element is connected to the support element via a hinge seat. One end of the guide post is hinged to the hinge seat, and the locking cap is fitted onto the other end of the guide post and can move axially along the guide post. A circular plate is located at the end of the guide post that extends into the locking cap, and a spring surrounds the guide post and is clamped between the circular plate and the bottom of the locking cap.

[0012] Furthermore, when the locking cap is pulled along the guide post, the spring is compressed, and the locking cap disengages from the first or second limiting plate; after the locking cap is released, the spring drives the locking cap to reset, so that the locking cap engages with the first or second limiting plate.

[0013] Furthermore, a waste collection assembly is provided on one side of the box, and a waste disposal door is connected to the box in an openable and closable manner. The collection bin is housed inside the box and located inside the waste disposal door.

[0014] Furthermore, the disposal flap is located inside the waste disposal door, and the hinge extends along the upper side of the disposal flap, rotatably connecting the disposal flap to the waste disposal door. A torsion spring is sleeved around the hinge, with one end of the torsion spring abutting against the waste disposal door and the other end abutting against the disposal flap, allowing the disposal flap to be pushed and flipped towards the collection bin, and to return to its original position after the external force is removed.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: By adjusting the support components and engaging the locking and limiting components, the anti-slip mat can switch between a storage position off the ground and a support position touching the ground. When the treatment cart needs to be moved, the anti-slip mat leaves the ground without affecting the normal rolling of the casters; when the treatment cart is parked and in use, the anti-slip mat presses against the ground, providing additional ground restraint for the cart.

[0016] The anti-slip mats undergo elastic deformation at the support position, which helps to improve their adhesion to the ground and increase the friction between the anti-slip mats and the ground, thereby reducing the possibility of the treatment cart slipping when pulling out storage drawers or taking out items.

[0017] The discharge flap can be reset by a torsion spring after waste is discharged, thereby shortening the time the waste discharge position remains open and reducing the adverse effects on the environment around the treatment vehicle caused by failure to close the discharge position in time.

[0020] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0021] like Figure 1 and Figure 2 As shown, a clinical treatment cart includes a housing 1, with a push handle 11 attached to one side, allowing medical staff to move the cart. A pull-out storage drawer 2 is housed within the housing 1 for storing medications, gauze, cotton swabs, and other treatment supplies used during clinical procedures. The housing 1 is supported by a base 3, with casters 32 attached to the bottom of the base 3, enabling the cart to move within wards, treatment rooms, or nursing areas.

[0022] An anti-slip component 4 is provided on the side of the housing 1 away from the push handle 11. The anti-slip component 4 can switch between a retracted state and a supported state. When the anti-slip component 4 is in the retracted state, its lower end is separated from the ground, and the treatment cart moves normally by means of the casters 32; when the anti-slip component 4 is switched to the supported state, its lower end presses against the ground, and the friction between the anti-slip component 4 and the ground restricts the slippage of the treatment cart.

[0023] The anti-slip component 4 includes a limiting member 41, a support member 42, a locking member 43, a roller 44, and a guide rail 45. The guide rail 45 extends along the height direction of the housing 1 and is fixed relative to the housing 1. The support member 42 is located on the outside of the housing 1, and its extension direction corresponds to the extension direction of the guide rail 45. The support member 42 can move up and down along the guide rail 45. An anti-slip pad 421 is connected to the lower end of the support member 42. The anti-slip pad 421 is used to abut against the ground after the support member 42 moves down.

[0024] The base 3 forms a clearance groove 31 along the downward movement path of the support member 42. The clearance groove 31 is located below the anti-slip pad 421, so that when the support member 42 moves downward, the anti-slip pad 421 can extend to the bottom of the base 3 through the clearance groove 31; when the support member 42 is in the upper position, the anti-slip pad 421 is above the ground and does not affect the rolling and turning of the caster 32.

[0025] like Figure 3 and Figure 4 As shown, roller 44 is rotatably connected to support member 42, and the wheel surface of roller 44 mates with guide rail 45. When support member 42 moves up and down, roller 44 rolls along guide rail 45, so that the direction of movement of support member 42 is constrained by guide rail 45, reducing lateral offset and swaying of support member 42 during movement.

[0026] Rollers 44 are spaced apart along the height of the support member 42, so that both the upper and lower parts of the support member 42 are guided by the guide rail 45. When the support member 42 is subjected to a downward force, the rollers 44 roll downward along the guide rail 45; when the support member 42 is subjected to an upward force, the rollers 44 roll upward along the guide rail 45. Through the rolling cooperation between the rollers 44 and the guide rail 45, the resistance when the support member 42 moves up and down can be reduced, allowing the anti-slip component 4 to complete the state switching more smoothly.

[0027] The limiting member 41 is arranged adjacent to the moving path of the support member 42 and remains fixed relative to the housing 1. The limiting member 41 includes a first limiting plate 411 and a second limiting plate 412, which are spaced apart along the moving direction of the support member 42. The first limiting plate 411 corresponds to the upper position of the support member 42, and the second limiting plate 412 corresponds to the lower position of the support member 42.

[0028] The locking member 43 is connected to the support member 42 and moves up and down synchronously with the support member 42. The locking member 43 can engage with the first limiting plate 411 and the second limiting plate 412 respectively, thereby keeping the support member 42 at different heights.

[0029] When the locking member 43 engages with the first limiting plate 411, the support member 42 is held in the upper position, the anti-slip mat 421 is separated from the ground, and the casters 32 provide support and movement for the treatment cart. This state corresponds to the stowed state of the anti-slip component 4, which prevents the anti-slip mat 421 from obstructing the normal movement of the treatment cart.

[0030] After the locking member 43 is released from the engagement with the first limiting plate 411, the support member 42 can move downward along the guide rail 45. As the support member 42 moves downward, the anti-slip pad 421 gradually approaches the ground and extends below the base 3 through the clearance groove 31. When the locking member 43 moves to the position corresponding to the second limiting plate 412, the locking member 43 engages with the second limiting plate 412, keeping the support member 42 in the lower position.

[0031] When the support member 42 is held in the lower position, the anti-slip pad 421 presses against the ground. The anti-slip pad 421 is made of a material capable of elastic deformation, such as rubber or an elastic material. The locking height corresponding to the second limiting plate 412 ensures that the anti-slip pad 421 forms an interference fit with the ground after the support member 42 is locked.

[0032] When the anti-slip mat 421 forms an interference fit with the ground, it undergoes elastic deformation due to the combined compression of the support member 42 and the ground. This elastic deformation increases the actual contact area between the anti-slip mat 421 and the ground, and generates a continuous pressure on the ground. Therefore, when medical staff pull the storage drawer 2, retrieve or place items, or apply a horizontal force to the box 1, the friction between the anti-slip mat 421 and the ground limits the slippage of the treatment cart caused by the applied force.

[0033] The anti-slip mat 421 allows the casters 32 to remain fully off the ground while in a supported position. The anti-slip mat 421 can bear part of the load on the treatment cart, reducing the load on the casters 32. Simultaneously, the friction between the anti-slip mat 421 and the ground increases the resistance the treatment cart needs to overcome when moving. This arrangement maintains the overall stability of the treatment cart while reducing cart movement caused by pulling out the storage drawer 2.

[0034] like Figure 5 As shown, the locking member 43 includes a locking cap 431, a spring 432, a guide post 433, and a hinge seat 434. The locking member 43 is connected to the support member 42 through the hinge seat 434, so that the locking member 43 can move up and down synchronously with the support member 42.

[0035] One end of the guide post 433 is connected to the hinge seat 434, and the other end of the guide post 433 extends toward the locking cap 431. The locking cap 431 is sleeved on the guide post 433 and can move along the axial direction of the guide post 433. A circular plate 4331 is provided at the end of the guide post 433 that extends into the locking cap 431, and the circular plate 4331 is located inside the locking cap 431.

[0036] A spring 432 is arranged around a guide post 433, with one end of the spring 432 abutting against a circular plate 4331 and the other end abutting against the bottom of a locking cap 431. The circular plate 4331 supports one end of the spring 432 and restricts the spring 432 from disengaging from its corresponding position along the guide post 433.

[0037] When the locking cap 431 moves away from the limiting member 41, the locking cap 431 is displaced relative to the guide post 433 and compresses the spring 432, causing the locking cap 431 to disengage from the first limiting plate 411 or the second limiting plate 412. After the locking cap 431 is released, the support member 42 can move up and down along the guide rail 45 under the action of external force.

[0038] After the support member 42 moves to the height corresponding to the first limiting plate 411 or the second limiting plate 412, the locking cap 431 is released. The spring 432 returns to its original deformation and pushes the locking cap 431 back to its original position, so that the locking cap 431 is re-engaged with the corresponding first limiting plate 411 or second limiting plate 412. Through the reset action provided by the spring 432, the locking cap 431 can maintain the corresponding engaged state after the operator releases their grip.

[0039] The hinge seat 434 provides the guide post 433 with a certain rotational adjustment space relative to the support member 42. When the locking cap 431 approaches the first limiting plate 411 or the second limiting plate 412, the locking member 43 can swing appropriately according to the contact position, so that the locking cap 431 corresponds with the first limiting plate 411 or the second limiting plate 412, which facilitates locking and unlocking.

[0040] When the treatment cart needs to be switched from the supported state to the mobile state, first pull the locking cap 431 to separate it from the second limiting plate 412; then move the support member 42 upward, causing the roller 44 to roll upward along the guide rail 45, and the anti-slip pad 421 to gradually release its interference fit with the ground and lift off the ground. When the locking member 43 reaches the position corresponding to the first limiting plate 411, release the locking cap 431, and the spring 432 drives the locking cap 431 to engage with the first limiting plate 411, thereby keeping the support member 42 in the stored position.

[0041] When anti-slip support is needed for the treatment cart, pull the locking cap 431 to release the engagement between the locking cap 431 and the first limiting plate 411, and then move the support member 42 down along the guide rail 45. The anti-slip pad 421 moves down the base 3 through the clearance groove 31 and contacts the ground. When the locking cap 431 reaches the position corresponding to the second limiting plate 412, release the locking cap 431, so that the locking cap 431 engages with the second limiting plate 412. At this time, the anti-slip pad 421 remains elastically pressed against the ground.

[0042] like Figure 2 and Figure 7 As shown, the container 1 is also equipped with a waste collection assembly 5, which includes a waste disposal door 51. A collection bin 6 is housed inside the container 1 and located inside the waste disposal door 51, for receiving waste generated during clinical treatment.

[0043] Waste disposal door 51 is closable and openable to the housing 1. When the collection bin 6 needs to be cleaned or replaced, the waste disposal door 51 can be opened to expose the collection bin 6 from inside the housing 1 so that the collection bin 6 can be removed. After cleaning or replacement, the collection bin 6 is placed back into the housing 1 and the waste disposal door 51 is closed.

[0044] The waste disposal door 51 is equipped with a disposal flap 511. The disposal flap 511 forms an openable part for daily waste disposal, allowing medical staff to put cotton swabs, gauze, gloves or packaging materials into the collection bin 6 without opening the entire waste disposal door 51 during normal use.

[0045] The upper side of the dispensing flap 511 is rotatably connected to the waste disposal door 51 via a hinge 53. The hinge 53 extends along the upper side of the dispensing flap 511, allowing the dispensing flap 511 to rotate around the hinge 53 toward the collection bin 6. When the dispensing flap 511 is in the closed position, it covers the dispensing position on the waste disposal door 51; when the dispensing flap 511 is subjected to an inward pushing force, it rotates around the hinge 53 toward the collection bin 6, thereby forming a channel for waste to pass through.

[0046] A torsion spring 52 is wound around a hinge shaft 53. One end of the torsion spring 52 abuts against the waste disposal door 51, and the other end abuts against the disposal flap 511. When the disposal flap 511 is pushed and flips around the hinge shaft 53, the torsion spring 52 undergoes elastic deformation and accumulates a restoring force. When the external force acting on the disposal flap 511 is removed, the torsion spring 52 releases its elastic force, driving the disposal flap 511 to rotate in the opposite direction around the hinge shaft 53, so that the disposal flap 511 returns to the closed position.

[0047] When disposing of waste, medical staff can use the waste or their hands to push the disposal flap 511, causing it to flip inwards into the container 1. The waste then falls into the collection bin 6 through the space created by the flap 511. After the waste passes through, the flap 511 automatically resets under the action of the torsion spring 52, re-covering the disposal position on the waste disposal door 51, thus preventing the disposal position from remaining open after use.

[0048] When using the treatment cart, medical staff first move the cart to the desired position using the push handle 11. Once in position, the locking member 43 is released from the first limiting plate 411, and the support member 42 moves downwards along the guide rail 45. When the anti-slip pad 421 presses against the ground, the locking member 43 engages with the second limiting plate 412, and the support member 42 is held in the supporting position by the second limiting plate 412. At this time, medical staff can pull out the storage drawer 2 to retrieve and place treatment supplies. The friction generated by the anti-slip pad 421 reduces movement of the treatment cart during the pulling action.

[0049] When waste is generated during treatment, the inward-pushing flap 511 can be pushed inward to dispose of the waste into the collection bin 6. After disposal, the inward-pushing flap 511 returns to the closed position under the action of the torsion spring 52. When treatment is completed and the treatment cart needs to be moved, the locking cap 431 is separated from the second limiting plate 412, the support member 42 is lifted upward to make the anti-slip pad 421 leave the ground, and then the locking cap 431 is engaged with the first limiting plate 411, and the treatment cart can then resume movement via the casters 32.

[0050] 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.
