Description

FIELD OF THE INVENTION

The present invention relates to a medical waste storage and transport system.

BACKGROUND OF THE INVENTION

This invention relates generally to a waste collection system for use in a hospital or a similar environment where assorted waste items are collected and disposed of without creating a hazard for patients or hospital personnel.

In hospitals, clinics and similar medical institutions, contamination continues to be of utmost concern. Hazardous patient care products such as sharps, tongue depressors and collection vials are disposed of in an appropriate hazardous waste container. In addition to hazardous patient care products, non-hazardous matter, laundry and/or recyclable items are commonly collected or disposed of in separate and distinct containers. The separate containers may be scattered across the hospital which may present a challenge for a medical practitioner to locate a particular container. Such an arrangement could cause a medical practitioner to inadvertently or intentionally deposit waste items in the wrong container.

Waste collection systems having a plurality of individual containers in one location currently exist, such as the stackable refuse container system disclosed in U.S. Pat. No. 5,445,397. The '397 patent discloses a stackable refuse container system that includes multiple stackable containers, each of which may be designated for holding a particular recyclable material. The containers are vertically stacked and a cart can be provided for transporting the stacked assembly to and from a curb. Each container may include a removable lid, a front portion of the lid being hingedly attached to provide access to the container and a second portion formed to engage and support a bottom of a complementary container.

Nevertheless, there remains a need for improved refuse receptacle systems in general and methods for separately disposing medical waste of different types in respective containers.

SUMMARY OF THE INVENTION

In one exemplary embodiment, a refuse receptacle system comprising a frame and a plurality of refuse containers supported by the frame is provided. Each of the refuse containers has a receptacle and a complimentary lid reciprocally movable with respect to the receptacle. The receptacle of each of the containers is supported by the frame and disposed at an angle in a range from about 10 to about 20 degrees from a vertical axis. A plurality of linkages are associated with the frame, whereby each linkage is coupled to the complimentary lid of one of the containers and is configured for reciprocation of the complementary lid between an open position and a closed position with respect to the receptacle.

In another exemplary embodiment, a refuse receptacle assembly configured for use with a plurality of refuse containers, each having a receptacle and a complimentary lid, is provided. The refuse receptacle assembly comprises a frame configured to support the receptacle of each of the containers at an angle in a range from about 10 to about 20 degrees from a vertical axis. A plurality of linkages are associated with the frame, whereby each linkage is configured to be coupled to a complimentary lid of one of the containers and is configured for reciprocation of the complementary lid between an open position and a closed position with respect to the receptacle.

In yet another exemplary embodiment, a method is provided for separately disposing of medical waste of different types in respective containers. The method includes the step of actuating a first foot pedal of a frame assembly to open a lid of a first container, thereby providing access to an interior of a receptacle of the first container. A first type of medical waste is deposited in the receptacle of the first container. A second foot pedal of the frame assembly is actuated to open a lid of a second container, thereby providing access to an interior of a receptacle of the second container. A second type of medical waste is deposited in the receptacle of the second container.

In still another exemplary embodiment, a method of configuring a plurality of containers for disposing of medical waste of different types in respective containers is provided. The method includes the step of positioning a receptacle of each container on a frame assembly at an angle in a range from about 10 to about 20 degrees from a vertical axis. The lids of the containers are positioned on the frame assembly for pivotal movement with respect to the complementary receptacles, whereby the lids of the containers are each operable with respective foot pedals.

DETAILED DESCRIPTION OF THE INVENTION

Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.

Referring generally to the figures, in one exemplary embodiment a refuse receptacle system 10, 10′, 110 comprising a frame 20 and a plurality of refuse containers supported by the frame 20 is provided. Each of the refuse containers have a receptacle 30 and a complimentary lid L_1-4 reciprocally movable with respect to the receptacle 30. The receptacle 30 of each of the containers is supported by the frame 20 and is disposed at an angle N in a range from about 10 to about 20 degrees from a vertical axis. A plurality of linkages K_1-4 are associated with the frame 20, whereby each linkage K_1-4 is coupled to the complimentary lid L_1-4 of one of the containers and is configured for reciprocation of the complementary lid L_1-4 between an open position and a closed position with respect to the receptacle 30.

In another exemplary embodiment, a refuse receptacle assembly 10, 10′, 110 configured for use with a plurality of refuse containers, each having a receptacle 30 and a complimentary lid L_1-4, is provided. The refuse receptacle assembly 10, 10′, 110 comprises a frame 20 configured to support the receptacle 30 of each of the containers at an angle N in a range from about 10 to about 20 degrees from a vertical axis. A plurality of linkages K_1-4 are associated with the frame 20, whereby each linkage K_1-4 is configured to be coupled to a complimentary lid L_1-4 of one of the containers and is configured for reciprocation of the complementary lid L_1-4 between an open position and a closed position with respect to the receptacle 30.

In yet another exemplary embodiment, a method of separately disposing of medical waste of different types in respective containers is provided. The method comprises the step of actuating a first foot pedal F₁, F₁₀₂ of a frame assembly 20 to open a lid L₁, L₁₀₂ of a first container, thereby providing access to an interior of a receptacle 30 of the first container. A first type of medical waste is deposited in the receptacle 30 of the first container. A second foot pedal F₂, F₁₀₂ of the frame assembly 20 is actuated to open a lid L₂, L₁₀₂ of a second container, thereby providing access to an interior of a receptacle 30 of the second container. A second type of medical waste is deposited in the receptacle 30 of the second container.

In still another exemplary embodiment, a method of configuring a plurality of containers for disposing of medical waste of different types in the respective containers is provided. The method comprises the step of positioning a receptacle 30 of each container on a frame assembly 20 at an angle N in a range from about 10 to about 20 degrees from a vertical axis. The lids L_1-4 of the containers are positioned on the frame assembly 20 for pivotal movement with respect to the complementary receptacles 30, whereby the lids L_1-4 of the containers are each operable with respective foot pedals F_1-4.

Referring now to FIGS. 1-4, a multiple container cart assembly embodying exemplary aspects of this invention is generally designated by the numeral “10.” The multiple container cart assembly 10, 10′ includes a transportable cart assembly 20 and four container assemblies that are mounted onto the cart assembly 20. Each container assembly includes a receptacle or container 30 that is configured to store waste and a pivotable lid L_1-4. If so desired, the different containers 30 are intended to accept different waste matter, such as medical waste, general waste, recyclables, laundry, etc. That is to say, if so desired, each container may hold a different type of waste or contaminated matter.

The multiple container cart assembly 10′ illustrated in FIG. 1 shows one lid L_1′ in an open position and foot pedal F_1′ in a depressed position. The remaining lids are illustrated in a closed position. The multiple container cart assembly 10 illustrated in FIGS. 2 and 3 show all lids L_1-4 in a closed position. In an open position of the lid, the container assembly is configured to receive waste. In a closed position of the lid, the container assembly is not configured to receive waste. Although not illustrated herein, a locking device may be utilized to restrict access to any of the containers.

Briefly referring to the overall operation of assembly 10, the lids L_1-4 of the containers are initially in a closed position as shown in FIGS. 2 and 3. To insert refuse or any other object into any one of the containers, the user depresses an appropriate foot pedal F_1-4 thereby pivoting the pivoting arm assembly A_1-4 and corresponding lid L_1-4 to an open position. The user deposits the refuse into the open container and releases the foot pedal F_1-4. Thereafter, the lid pivots to a closed position, by virtue of the weight of the lid (aided or unaided by additional biasing means such as a spring or a weight), and the foot pedal naturally returns to its initial position.

It should be understood that foot pedal F₁ is indirectly connected to pivoting arm assembly A₁ that engages lid L₁. Similarly, foot pedal F₂ is indirectly connected to pivoting arm assembly A₂ that engages lid L₂, and so forth. The kinematic relationship between the foot pedal and its corresponding pivoting arm will be described in further detail later.

The multiple container cart assembly 10, 10′ is commonly employed in a hospital or medical office setting. In such a setting it is desirable to maximize the capacity of the cart assembly to accept more waste, and, yet conversely, it is also desirable to minimize the size of the overall assembly so that the assembly consumes minimal floor space in the hospital. Furthermore, it is also desirable to position the containers such that they are user-accessible (i.e., in reach) so that the user may deposit refuse into the appropriate containers, replace a filled container with an empty container, or replace a refuse bag with minimal effort. This is especially advantageous in an environment, such as a medical environment, in which medical waste must be sorted for appropriate disposal.

The containers on the top row are also positioned so as to provide clearance for the rotation of the container lids on the bottom row. This allows free usage of the various containers without physical interference among their moving components.

It has been discovered that it is advantageous to position the entire body of the container 30 onto the cart assembly 20 at an angle “N” (see FIG. 3) relative to a vertical axis to satisfy the aforementioned space constraints such as those found in a hospital setting. In one exemplary embodiment the angle N is about 10 to about 20 degrees. In another exemplary embodiment, the angle N is preferably about 15 degrees. Although all of the containers 30 are positioned at the angle N, as illustrated in the figures, the containers may be positioned at different angles relative to one another. Furthermore, although the entire body of receptacle 30 is angled with respect to a vertical axis in this embodiment, in another exemplary embodiment not illustrated herein, only the top of the container body is angled with respect to a vertical axis.

The height, the width, and the length of the assembly can be selected based on the capacity, quantity, and shape of the containers that the assembly accommodates because the capacity, quantity, and/or shape of the containers can vary widely in a single assembly or from one assembly to another.

Referring specifically to FIG. 4, each container 30 is mounted onto a set of two support arms 52, which are fixedly coupled to the frame (one support arm shown in FIG. 4). More specifically, a mounting portion 31 formed on both sides of each container 30 is positioned to receive the mounting segments 63 of the support arms 52 (see FIG. 8). In addition to operating as a mount for the container, mounting portion 31 is also provided as a handle for the user to grasp upon removing and/or installing the container or a lip of the receptacle component of the container. Another mounting portion 131, which is identical to mounting portion 31, is more clearly illustrated in FIG. 13. The mounting portion 31 merely rests on the support arms 52, as the support arms 52 and the container are not fastened together. Thus, the container 30 is readily removable from the cart assembly 20.

The mounting portion 31 may also be in the form of an aperture, lip, shoulder or protrusion, for example, formed on the body of the container. Although one mounting arrangement is illustrated in the figures, it should be understood that a number of other mounting arrangements are contemplated. For example, the container may be fixedly mounted to the support arm 52 with a fastener. Moreover, the container may be simply positioned within a cavity 23 of the cart body or directly coupled to the cart body 24 (the cart body 24 is exclusively illustrated in FIG. 11). It will be appreciated that the container may be positioned at the cart assembly in a wide variety of manners and can be releasably or fixedly mounted to a portion, such as a frame portion, in any number of ways, depending upon the preference of the user, the configuration of the container(s), and other factors.

The container 30 may be composed of a rubber or plastic material and formed by any forming process, such as rotational molding, blow molding or injection molding. Alternatively, the container body may be composed of a metallic material that is substantially puncture resistant. The container 30 and lid L_1-4 may also be any commonly available waste container such as those comprised of a receptacle and lid combination.

As illustrated in FIG. 4, the lid L_1-4 is not directly coupled to the receptacle 30. A gap “G” optionally exists between the Lid L_1-4 and the container 30 to accommodate the lid retaining segments 56 and 57 (See FIG. 8) of the pivoting arm assembly A_1-4 However, in another exemplary embodiment, the lid is pivotably coupled to either the container 30 or the cart shell 24.

Referring now to FIGS. 5-8, the cart assembly 20 of this exemplary embodiment generally comprises a frame 40, four linkage assemblies K_1-4 mounted to the frame, and a hollow cart shell 24 (omitted for clarity in FIGS. 5-8) positioned to conceal a portion of the frame 40.

The frame 40 generally includes the base plate 22 and an arrangement of rigid bars and beams fastened or welded together. More particularly, the frame includes vertical members 42 fixedly mounted to the base plate 22 and cross members 41 fixedly mounted to the vertical members 42. The cross members 41 are positioned to stabilize, support and reinforce the entire frame assembly. A C-beam 43 is fixedly mounted to rear vertical members 42, and a bracket 44 is mounted to front vertical members 42 (best shown in FIG. 6).

Referring still to the frame assembly 40, two rectangular mounting brackets 54 are fastened or welded to the C-beam 43 to support the top row of containers 30, and two mounting brackets 54 are fastened or welded to the C-beam 43 to support the top row of containers 30. Four sets of support arms 52 are welded or fastened to the front side of the respective mounting brackets 54. As mentioned previously, each container 30 is positioned on a complimentary set of support arms 52. A support rod 62 extending between each set of support arms 52 and fastened thereto is provided to reinforce the support arms 52.

Four sets of support rods 61 (best shown in FIG. 6) are welded or fastened to the front side of respective mounting brackets 54. It should be understood that the support rods 61 do not rotate or translate, rather, the support rods are fixed in position and the arm assembly (described in further detail below) pivots about them. A support rod 58 is welded or fastened to the front side of the mounting brackets 54, as best illustrated in FIG. 9. The purpose of the support rod 58 will be described in further detail later with respect to the linkages.

An optional set of wheels or casters 21 are pivotably mounted to the underside of the base plate 22. Although not shown, an optional handle or other apparatus mounted to the exterior of the cart shell 24 or frame assembly 40 may be provided to guide the motive assembly 10. It is envisioned that a motor or other device (not shown) could be linked to the wheels to provide automated motion.

A pedal bracket 45 and a set of four pulleys P_1-4 are fixedly mounted to the top side of the base plate 22, the purpose of which will be described in further detail later with reference to the linkages.

The frame assembly 40 components may have any cross sectional shape, as they are not limited to the illustrations, and may be composed of any common rigid material, such as steel or aluminum, to effectively support the containers 30. The frame 40 is not limited to the illustration shown, as the bars and the beams may be arranged in many different configurations to sufficiently support the containers and the cart shell 24.

The cart assembly 20 of the exemplary embodiment illustrated in FIGS. 5, 7 and 9 includes four separate linkages K_1-4 mounted to the frame 40. Each linkage assembly of this exemplary embodiment includes a foot pedal F_1-4 pivotably coupled to one end of a cable C_1-4 and a pivoting arm assembly A_1-4 pivotably coupled to an opposing end of the cable C_1-4, respectively. It should be appreciated that any number of linkage assemblies K_1-N can be employed according to this exemplary embodiment, each includes a foot pedal F_1-N pivotably coupled to one end of a cable C_1-N and a pivoting arm assembly A_1-N pivotably coupled to an opposing end of the cable C_1-N, respectively. Inasmuch as the separate linkages K_1-4 are substantially equivalent in structure and operation, linkage K₃ will be described in detail with the understanding that like reference numerals will be used for like structure in each linkage. Accordingly, linkage K₃ is singularly illustrated in FIGS. 6, 8 and 10 (linkages K_{1, 2, 4} have been omitted for brevity).

Referring now to the linkage assembly K₃ illustrated in FIGS. 6, 8 and 10, the foot pedal F₃ pivots about a rod 59. The rod 59 extends into an aperture defined in a pedal bracket 45, as best illustrated in FIG. 6. A nut, pin or other fastener (not shown) captivates the rod 59 within the pedal bracket aperture, although it should be understood that the fastener permits rotation of rod 59 about the aperture. The cable C₃ is pivotably or otherwise coupled to an end portion of the pivoting foot pedal F₃.

The cable is thereafter routed through a pulley P₃ and is pivotably or otherwise coupled to a cable connecting arm 55 of the pivoting arm assembly A₃. The pivoting arm assembly comprises a bracket 51, a wire-form pivoting arm 50 fixedly mounted to the underside of the bracket 51, and the cable connecting arm 55 which is fastened or welded to the rear side of the bracket 51. The bracket 51 includes an aperture through which a support rod 61 is inserted, such that the bracket 51 pivots about the fixed support rod 61.

As best illustrated in FIG. 8, the bracket 51 includes a lid retaining segment 56 which engages the rear end of a lid. Similarly, the pivoting arm 50 includes a lid retaining segment 57 which engages the front end of the lid. Another lid retaining bracket 60 fixedly mounted to the pivoting arm 50 engages the sides of the lid. In combination, the lid retaining segments 56, 57 and 60 retain the lid in a substantially fixed position, and accordingly, the lid (e.g., L₃) pivots along with the pivoting arm assembly A₃.

In use, when the foot pedal F₃ is depressed (i.e. rotated in a counterclockwise direction when viewed from the right) the foot pedal pulls the cable C₃ along the pulley P₃, which in turn rotates the cable connection arm 55 downward in a clockwise direction. The entire pivoting arm assembly A₃ and lid (e.g., L₃) rotates in the clockwise direction along with the cable connection arm 55.

A dampening element 53 is optionally included to facilitate smooth and controlled rotation of the lid. One end of the dampening element is pivotably coupled to the support rod 58, as best illustrated in FIG. 9, and the other end of the dampening element 53 is pivotably coupled to the rear side of bracket 51, as best illustrated in FIG. 8. The dampening element 53 may be pivotably mounted to both bracket 51 and support rod 58 so that it is permitted to pivot along with the pivoting arm assembly A₃. The dampening element of this exemplary embodiment may be any commonly available spring or strut known in the art.

The pivoting arm assemblies A_1-4 and foot pedals F_1-4 may have any cross-sectional shape, as they are not limited to those in the illustrations, and may be composed of any common rigid material, such as steel or aluminum. The cables C_1-4 may be composed of any flexible, non-yielding material having a sufficient tensile strength for its intended purpose.

An exemplary embodiment of a cart shell 24 is illustrated in FIG. 11. The cart shell comprises four cavities 23 positioned to accommodate the container bodies 30. Each cavity includes an aperture(s) 25 to accommodate the respective linkages K_1-4. The cart shell embodiment illustrated herein does not cover or conceal the bottom side and rear side of the cart assembly 10. However, in another exemplary embodiment, the cart shell may cover either the bottom side or rear side of the cart assembly 10 if so desired. The cart body may be formed by a forming process, such as rotational molding, blow molding or injection molding. Alternatively, the cart shell may be composed of individual components fastened together.

The design of the side walls 26 and sloping walls 27 are ornamental features of the cart shell 24 illustrated in FIG. 11. The cart shell can have a wide variety of ornamental shapes and configurations, including a variety of proportions, thicknesses, cross-sections, and curvatures.

Another exemplary embodiment of a multiple container cart assembly 110 is illustrated in FIGS. 12 and 13. The multiple container cart assembly 110 generally includes two vertically adjacent containers 130 having lids L₁₀₁ and L₁₀₂ that are mounted onto a cart assembly 120. Accordingly, similar to the prior exemplary embodiment, two foot pedals F₁₀₁ and F₁₀₂ are provided to pivot the lids L₁₀₁ and L₁₀₂, respectively, between an open and a closed position (as shown).

Since the cart assembly 110 includes two containers 30, the cart shell 124 differs from the cart shell 24 illustrated in the previous embodiment. That is, cart shell 124 includes two cavities instead of four cavities to accommodate the containers. An accessory tray 126 is optionally mounted to either the cart frame or the cart shell 124. The tray 126 may be a storage bin to stow a supply of gloves, for example, or any other commonly used item.

As best illustrated in FIG. 13, a support rod 123 is fixedly mounted to either the frame or the cart shell 124. In practice, a waste bag (not shown) is coupled or suspended from the rod 123 to accept medical or other waste. A lid 127 is either hingedly coupled to the rod 123, the frame or the cart shell 124, to pivot between an open position and a closed position (as shown). In the open position of lid 127, a user may deposit waste into the bag. Unlike lids L₁₀₁ and L₁₀₂, a foot pedal and corresponding linkage is not coupled to lid 127, thus, in use, the user pivots the lid between an open position and a closed position by hand. However, it is contemplated that a linkage similar to the previously described linkages may be incorporated to engage lid 127.

While preferred embodiments of the invention have been shown and described herein, it will be understood that such embodiments are provided by way of example only. Numerous variations, changes and substitutions will occur to those skilled in the art without departing from the spirit of the invention. Accordingly, it is intended that the appended claims cover all such variations as fall within the spirit and scope of the invention.

Furthermore, it should be understood that the structure of the frame 40 and linkages K_1-4 may deviate from the illustrations, as numerous configurations of both the frame 40 and linkages K_1-4 are contemplated. Although four containers 30 are illustrated herein, the multiple container cart assembly 10 may include any number of containers. The containers may be of any adequate size to achieve the same purpose and may be positioned in any orientation depending upon the needs of the user. Furthermore, although the containers are positioned on a single side of the cart, the containers may be positioned on opposite sides of the cart.
