1. Field of the Invention
The invention generally relates to infection control systems used in hospitals, skilled nursing facilities, and in nursing homes, and more particularly to disposable trash bag systems for contaminated trash generated by patients lying in a hospital bed.
2. Description of the Related Art
Patients lying in a hospital bed generate personal trash such as gum, facial tissues, napkins, and paper towels that must be properly discarded to prevent the spread of infections.
While most patients know that the trash they generate may be contaminated and should be properly discarded, the personal trash they generate is sometimes left on the overbed table, on the bedding, or dropped on the floor because a trash receptacle was not within easy reach of the patient when lying in the bed. Eventually, the trash is picked up by a healthcare worker or by a family member and deposits it into floor trash receptacle. Unexpectedly, the worker or family member may be contaminated with germs and viruses from the patient.
Overbed tables are commonly used in a hospital to serve food or beverages to a patients lying in a bed. Overbed tables are also used by patients as support surfaces for temporarily holding books, magazines, or for writing or for playing cards. They typically include a rectangular table top mounted at one end to a height adjustable vertical column. The table top is a single, planar structure with a uniform thickness and made of hard, laminated plastic that can be thoroughly sanitized with a suitable disinfectant is manually applied by housekeeping personnel. The lower end of the vertical column is mounted on a low profile base with caster wheels that allows the base to easily roll across the floor and, if desired, extend under the bed. During use, the overbed table may be moved to different positions around the bed to accommodate different positions of a patient lying on a hospital bed, and to accommodate different pieces of medical equipment that may be setup around the bed.
What is needed is a disposable trash bag holder system that holds a disposable trash bag at different locations around a patient lying in different locations on a hospital bed. Such a system should enable the disposable trash bag to be selective moved to accommodate the different positions of the patient in the bed. What is also needed is a system that supports a trash bag in partially open configuration so trash can be easily deposited into the bag without manually manipulating the bag. What is also needed is a holder system that can store or position other objects commonly used by patients lying in a hospital bed including but not limited to beverage containers, tissue or swipe containers, writing implements, gum containers, etc.
What is also needed is a system that satisfies the above needs that does not interfere with commonly used housekeeping tasks employed to reduce bacterial and viral infections in the facility.
It is an object of the invention disclosed is to provide a disposable trash bag system that includes a holder designed to hold a disposable trash bag in a partially open configuration so it may be easily filled with soiled tissues or objects by the patient laying at different positions and locations in a hospital bed.
It is another object to provide a disposable trash bag system that uses the table top of an overbed table that can be easily moved to different gross locations around patient and can be manually disinfected with a suitable agent.
It is another object to provide such a system that uses a bag holder can be selectively attached and removed from the table top and allows the disposable bag to be easily inserted and removed from the holder using minimal contact to the table top surface, the holder or the bag.
It is a further object to provide a holder system that may also be used to store or conveniently position objects commonly used by patients lying in hospital bedding including but not limited to beverage containers, tissue or swipe containers, or writing implements, that also may contaminated.
These and other objects of the invention are met by system for preventing the spread of infection in a healthcare facility where patients positioned on beds generate personal trash or hold objects that may be contaminated. The system is designed to so the patient themselves may easily dispose of their trash directly into a disposable trash bag or store objects they commonly used so others do not have to handle the trash or the objects. A key feature of the system is using an overbed table that can be repositioned around the bed and a holding device can that selectively attached at any location to the overbed's table perimeter edge. The combined benefits of a moveable overbed table and a holding device can be attached at any location to the table's edge, allows a disposable bag or an object container to be positioned within easy reach of any patient lying in the bed.
More specifically, the system includes an overbed table with a flat, elongated table top with a bag holding device selectively attached at any location to the table top's perimeter side edge. In one embodiment, a bag holder is used in which a disposable trash bag is inserted and rests vertically via gravity over a support structure. Typical overbed tables have a table top that has a uniform thickness and a continuous exposed perimeter side edge. In one embodiment presented, the bag holding device includes two parts—a holding member and an intermediate member. In one embodiment, the holding member and intermediate member are detachable and prior to use, selectively attached to hold an opened disposable bag in a vertically configuration on the side of a table top. The intermediate member attached to the holding member is configured to sufficiently extend laterally from the perimeter side edge and can be selectively attach at any location to the overbed's perimeter side edge. When the bag holding device is made out of two components, the intermediate member may remain attached to the table top and the holding member may be selectively removed enabling housekeeping personal to sanitize the bag holder device and the table top surface.
In the embodiment shown, the holding member includes a rigid ring element with a center opening configured to receive a disposable trash bag closed at one end. The ring structure is circular and acts as a support surface for the upper edge of the disposable trash bag. In one embodiment shown, the disposable trash bag is similar to a small emesis bag with an outer plastic bag body closed at one end and with an upper cardboard ring member disposed around the bag body's top opening the top opening remains open at all times when hung from the ring element. The cardboard ring member also provides rigidity and acts as a semi-rigid support surface for holding the bag body on the ring element.
The ring element is a circular structure and the ring member is a complimentary structure that rests on top of the ring element when the trash bag is installed. In other embodiments, the ring element and the ring member may have other configurations that together temporarily hold the bag body in opened, vertically aligned position for filling.
In the embodiment shown, the intermediate member includes an upper leaf that slides over or snaps fits over the top surface of the overbed's table top, and a lower leaf that slides over or snaps fits over the bottom surface of the overbed table top. The upper and lower leaves are spring-biased to apply light forces on opposite top and bottom surfaces to hold the intermediate member over the perimeter edge of the table top. In other embodiments, the intermediate member may have other configurations that enable it to selectively attach to perimeter edge of the table top.
As mentioned above, In one embodiment, the bag holding device is made of two separate parts—a holding member and an intermediate member. It should be understood that the bag holding device may be one part wherein the holding member and the intermediate member may be integrally attached or formed together.
In other embodiments, the disposable bag is replaced with one or two types of container holders designed to hold other loose objects or containers. In one embodiment, the container holder is a cup-style holder that includes an upper ring member configured to rest on top of the ring element and a downward extending cup with pendent side walls and a bottom surface. In another embodiment, the container holder is a cage-style structure made of two or more U-shaped clips connected together and configured to be supported and held by the ring element when inserted into the center opening on the ring element. In both embodiments, central storage areas are formed in which objects handled by the patient may be placed.
It should also be understood, that the system is defined as used with an overbed table typically used with large beds in which patients are position for rest and medical treatment in a medical treatment facility or department, such beds as a hospital, a medical clinic, a retirement center, an outpatient surgical facility, an alcohol or drug treatment facility, a prison, or a school. It should be understood however, that other types of table top structures may be used in place of the overbed table.
During use, the overbed table may be selectively moved to different locations around the bed that accommodates the patient's position and the medical equipment around the bed. A suitable location on the perimeter edge for the intermediate member is then selected that places the disposable bag or container object for holding an object in a convenient location for the patient. The intermediate member is then attached to the perimeter edge. A disposable bag or container holder is then selected and extended through the ring element's center opening. Discarded personal trash can then be disposed into the bag body or a beverage container, tissue or swipes container or a writing implement may be in the container holder.
The system 8 includes a holding member 40, one of two intermediate members 60 or 70 disposed between the holding member 40 and the table's perimeter side edge 25, 25′, respectively. In one embodiment, the holding member 40 includes a flat ring element 41 and a laterally extending receiving body 42. Formed inside the ring element 41 is a center opening 46 configured to receive a disposable trash bag 80 or container 90, 100 described further below.
The disposable trash bag 80 is similar to a small emesis bag with an outer plastic bag body 81 with a semi-rigid upper ring 82 disposed around its top opening. In one embodiment, the upper ring 82 is made of cardboard or paper that provides weight and mass and acts as a semi-rigid support surface for expanding and holding the bag body 81 on the top surface of the ring element 41. The bag body 81 has a volume of approximately 1 quart.
Attached or formed on the outside surface of the receiving body 42 is a receiver 50 that includes at least one slot 52 designed to receive a sleeve member 62 or 72 formed on the two intermediate members 60, 70, respectively. Both intermediate members 60, 70 include a biased perimeter edge engaging member designed to snap fit over the table top's top surface 26. The first embodiment of the intermediate member 60 shown in
In a second embodiment, shown in
As shown more clearly in
During use, the overbed table 10 may be moved so the table top 24 can be positioned at any desirable location adjacent or partially over the patient. The intermediate member 60 or 70 may be moved to any desired location on the perimeter side edge 25, 25′, respectively, to accommodate the table top's new location relative to the patient.
In another embodiment, the disposable trash bag 80 is replaced with one or two types of container holders, a cup-style container holder 90 and a cage-style container holder 100, each configured for placement inside the center opening on the ring element 41.
The holders 90 and 100 may be made of disposable material, such as stiff cardboard, paper stock material, or made of non-disposable material, such as plastic or metallic material.
An overbed table 10 is first selected and positioned at a desired location over the bed that accommodates the needs of the patient and the healthcare worker. A holding member 40 with a suitable intermediate member 60 and 70 configured to engage the perimeter side edge 25, 25′ of the table top 24, 24′, respectively, is then selected. A suitable location on the perimeter edge 25, 25′ for the holding member 40 is then selected so trash may be easily placed into the trash bag 80 when attached thereto. The intermediate member 60 or 70 is then attached to the perimeter side edge 25, 25′ on the overbed table 10. The upper and lower leaves 66, 68 and 76, 78 on the intermediate member 60 and 70, respectively, are pulled apart and pressed onto the perimeter side edge 25, 25′, respectively. The slots 52 and 54 on the receiver 50 are then aligned over the vertical sleeve member 62, 72 and the receiver 50 is then forced downward to engage the intermediate member 60, 70, respectively. Alternatively, the intermediate member 60 or 70 may be attached to the sleeve member 62, 72 prior to attaching the intermediate member 60 or 70 to the perimeter side edge 25, 25′.
If a disposable trash bag 80 is desired, it is unfolded, and inserted into the center hole 46 formed in the ring element 41. The disposable bag's outer bag body 81 extends through the center opening 46 and the upper ring 82 is disposed over and positioned against the top surface of the upper flat ring element 41. Trash may then be disposed into the bag body 81. When full, the trash bag 80 expands and hangs downward from the upper ring element 41. The full trash bag 80 may be removed and discarded from the ring element 41 and replaced with a new trash bag 80. When the location of the disposable trash bag 80 is changed or when the table top 24, 24′ needs to be cleaned with a suitable disinfectant, the intermediate members 60 and 70 are detached from the perimeter side edge 25, 25′.
If a container holder is desired, then either the cup-style container holder 90 is selected or a cage-style holder 100 is selected. Which container holder 90, 100 is selected depends on the object to be stored.
