FIELD OF THE TECHNOLOGY
The present disclosure relates generally to hygiene practices, and more particularly to improved infection control station systems and methods.
BACKGROUND
Applicants desire systems and methods for hygiene practices to improve infection control and inventory management, without the drawbacks presented by the traditional systems and methods.
SUMMARY
In accordance with the present disclosure, control stations and methods are provided to ensure proper hygiene practices and inventory management. This disclosure provides improved patient room arrangements and user control stations that are convenient, efficient, and safe for the user, particularly when used in medical environments.
In one embodiment of the present disclosure, a patient infection control and inventory management arrangement includes a patient evaluation and treatment area, at least one patient bed, and a user control station typically aligned adjacent the entry and exit access. The arrangement typically includes a substantially enclosed patient evaluation and treatment area, i.e. a medical room, a patient hospital room, or the like, having at least one entry and exit access. The patient bed is typically positioned within the treatment area. The control station typically includes a supply inventory management system, a user interface, and an automated activation system. Typically, the supply inventory management system has a plurality of picking compartments housing infection control inventory and a counter in communication with the picking compartments to detect and monitor usage of the inventory. The control station, including the user interface, typically identifies a user and automatically coordinates best hygiene practice steps based on the user identification. The automated activation system typically activates the station to allow access to the picking compartments and to generate the best hygiene practice steps when the identified user enters a predetermined proximity of the control station.
In particular examples, the patient infection control and inventory management arrangement includes a user alignment floor mat. In some examples, the user alignment floor mat may be spaced from the user interface, or the like, to properly align the user for full view and/or function with the control station.
In another embodiment, a user control station positioned in a patient infection control room includes a user interface, an automated activation system, and a sterilizer system. The user interface typically identifies a user and generates best hygiene practice instructional steps, for instance to operate the user station based on the user identification. The automated activation system typically activates the station to generate the instructional steps when a user enters a predetermined proximity of the station. The sterilizer system typically includes an ultraviolet radiation source that is generally aligned, for instance in an illumination path or the like, with a sterilizing bay, or similar area, to sanitize a user's personal device or the like.
In some examples, the user interface includes a telescoping connection to rotate and pivot the user interface about the control station. The user interface may include a touch-screen monitor having a staff entry portal and a visitor entry portal, for instance the staff entry portal may allow a predetermined access within the user station and the visitor entry portal may allow limited predetermined access within the control station. The user interface may include a staff best-hygiene practices instructional video and a visitor best-hygiene practices instructional video. The automated activation system may include a triggering device, for instance a sensor curtain, a camera, a motion sensor, an RFID recognition sensor, a combination thereof, and the like. The sterilizer system may include an ultraviolet waste container sanitizer. The control station may be repositionable around the infection control room.
In yet another embodiment, a user control station positioned in a patient infection control room may include a plurality of picking compartments, a plurality of inventory replacement slots, an automated activation system, and a counter system. Typically, the plurality of picking compartments have a body to generally house infection control inventory, and the like, and a picking opening to expose the infection control inventory, and the like. The plurality of inventory replacement slots are typically positioned adjacent to the picking compartments and to access to the picking compartments for replacing the inventory. The automated activation system typically activates the station to allow access to the picking compartments, for instance when a user enters a predetermined proximity of the control station. The counter is typically in communication with the picking compartments and detects and monitors usage of the inventory, i.e. the counter may deduct supplies used from an inventory listing or similar database in communication with the control station.
In some examples, the automated activation system includes a triggering device, for instance a sensor curtain, a camera, a motion sensor, a radio frequency identification (RFID) sensor, a combination thereof, and the like. The picking compartments may include gown picking compartment, a plurality of safety glove sizes picking compartments, a face mask picking compartment, a combination thereof, and the like. The safety glove picking compartments may include a large glove picking compartment, a medium glove picking compartment, a small glove picking compartment, a combination thereof, and the like.
The counter may count a used gown, a used glove, a used face mask, a combination thereof, and the like. The counter may include a low level alert to indicate a low inventory based on deductions of supplies used from the inventory listing/database. For instance, the low level alert may be an electronic message delivered to a remote device or the like.
In particular examples, the lower portion may have a plurality of supply compartments that are generally positioned below the picking compartments. For instance, the supply compartments may include a first compartment to store gloves, masks and gown supplies; a second compartment to store soap, sanitizer, and paper towels; and a third compartment to store miscellaneous supplies. The control station may include a keyless autolocking system to lock any of the picking compartments and the like. Further, the control station may be repositionable around the infection control room.
One aspect of the present disclosure is to provide a medical patient room with improved hygiene control for staff and visitors. In some examples, the room includes control stations having auto-inventoried picking compartments. In other examples, the control stations include sanitizing components to sanitize a variety of user, i.e. visitor and staff, materials.
Another aspect of the disclosure is to provide a control station with secured refill storage. In particular examples, the control stations include automated sensing systems and user interface instructions.
The above summary was intended to summarize certain embodiments of the present disclosure. Embodiments will be set forth in more detail in the figures and description of embodiments below. It will be apparent, however, that the description of embodiments is not intended to limit the present inventions, the scope of which should be properly determined by the appended claims.
