## Background
FIELD OF THE INVENTION
The present invention relates generally to dispensing articles, and more specifically, to a vending machine for dispensing scrubs with time expiring badges and associated methods.
BACKGROUND OF THE INVENTION
In sterile patient care areas such as an operating room, a medical lab, or a procedural room, personnel typically wear surgical scrubs and caps. According to national regulatory guidelines, properly laundered scrubs should be worn when a person enters a sterile department and removed before leaving. Compliance to this protocol in and out of the operating room may be important in reducing cross contamination and healthcare-associated infections.
These regulatory guidelines may not only be applicable to hospital personnel, but also to sales representatives or vendors that enter an operating room to witness procedures and sell medical devices and implants. Typically, the hospital provides the sales representatives or vendors with scrubs at the hospital's own expense. However, the monitoring and tracking of the daily inventory of these scrubs can be difficult and expensive. Scrubs may be consistently lost resulting in further expense to the hospital.
Due to issues with inventory control, sales representatives or vendors may find it increasingly difficult to find a full set of scrubs in an appropriate size at any one hospital. As a result, it is not uncommon for a sales representative to continue wearing the same set of surgical scrubs throughout the day while visiting different hospitals.
Scrub dispensing devices have been developed to control the inventory and distribution of scrubs in a medical facility. For example, U.S. Pat. No. 5,638,985 to Fitzgerald et. al, discloses a vending machine for dispensing articles, such as scrub garments, that has multiple rows of slots that can store the scrubs. The rows are vertically stacked with a separate lockable door on each level and between each slot so that only a single slot may be accessible. Additionally, U.S. Pat. No. 6,223,934 to Shoenfeld, discloses a scrub dispenser cabinet for dispensing differently sized garment tops and bottoms to customers. A user is able select a preferred size scrub which is then dispensed via a system of wheels and belts. Also related to scrub dispensing, U.S. Pat. No. 7,474,938 to Poliner discloses an interactive automated article dispensing device that also includes a user credit tracking system for tracking a number of articles a user is authorized to have dispensed.
Unfortunately, these systems may not reduce the likelihood of the dispensed scrub from being worn by a user over a long period of time in different hospitals and operating rooms. Thus, further improvements may be desirable.
SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide a vending machine for dispensing scrubs to address inventory issues and address the possibility of scrubs being worn in multiple hospitals in the same day, for example. The vending machine may include a housing configured to store different sized scrubs. The vending machine also may include a scrub dispenser, a labeler, a controller carried by the housing. The controller may be configured to cooperate with the scrub dispenser to dispense a selected sized scrub. The controller may also be configured to cooperate with the labeler to generate a time expiring badge for the selected sized scrub. The labeler may be configured to print indicia on a first badge substrate, and the first badge substrate may be attachable to a second badge substrate carried by the selected sized scrub to define the time expiring badge. Accordingly, the dispenser provides inventory for scrub dispensing, and the time expiring badge may discourage over-extended wearing of the dispensed scrubs.
The vending machine may also include a communications interface carried by the housing and coupled to the controller. The controller may be configured to communicate with a remote station via the communications interface. The controller may be configured to receive user authorization from the remote station. Additionally, the controller may be configured to receive data relating to the selected sized scrub from the remote station. Further, the controller may be configured to receive user related information from the remote station and incorporate the user related information in the time expiring badge. The user related information may include, for example, at least one of a user name, a hospital where the user is, and a date of authorization of the user.
Additionally, the vending machine may also include a user interface carried by the housing. The controller may be configured to cooperate with the user interface to identify the user.
A method aspect is directed to a method for vending different sized scrubs stored in a housing of a vending machine for scrubs. The method may include operating a controller carried by the housing to cooperate with a scrub dispenser carried by the housing to dispense a selected sized scrub, and cooperate with a labeler carried by the housing to generate a time expiring badge for the selected sized scrub.

Referring initially to FIGS. 1 and 2, a vending machine 10 for scrubs is now described. The vending machine 10 illustratively includes a vending machine housing 12 configured to store a plurality of different sized scrubs 14. The scrubs may be, for example, a scrub shirt, a scrub pants, scrub shoe covers, a scrub cap, a scrub coverall, a lab coat, and the like. As those skilled in the art will appreciate, other scrub garments may be stored in the vending machine housing 12. In one embodiment, the plurality of different sized scrubs 14 may be arranged into a plurality of different scrub packs, with each scrub pack including scrubs of the same size. As one in the art will appreciate, this configuration may increase the likelihood that a user 16 may receive a full scrub outfit with each scrub being of the same size. Additionally, a scrub pack can provide additional rigidly and make dispensing of the scrubs easier. However, it may be possible that individual scrub garments are arranged in the vending machine. A Radio-Frequency Identification Tag may also be carried by the scrub to help monitor the location of each scrub. Of course, other technologies and techniques for monitoring the location of scrubs may be used.
In some embodiments, a scrub holding device may be carried by the vending machine housing 12 to support the plurality of different sized scrubs 14. The scrub holding device may include one or more shelves, trays, slots, cubbies, or the like. Advantageously, this configuration may allow the plurality of different sized scrubs 14 to be arranged in the vending machine housing 12 by size.
A scrub dispenser 18, a labeler 20, and a controller 22 are also carried by the vending machine housing 12. The controller 22 is configured to cooperate with the scrub dispenser 18 to dispense a selected sized scrub 24. In one embodiment, the scrub dispenser 18 may include a helical dispensing member, a motor coupled to the helical dispensing member, and a receiving bin. Advantageously, a scrub may be placed proximate the helical dispensing member and as the helical dispensing member rotates, the foremost scrub may be pushed into a receiving bin from which a user 16 can retrieve the selected sized scrub 24. Those of skill in the art will, however, appreciate other electrical mechanical arrangements for dispensing scrubs.
The controller 22 may cooperate with the labeler 20 to generate a time expiring badge 26 for the selected sized scrub 24. The labeler 20 may be, for example, a thermal printer, an ink-jet printer, or other printing devices known to those skilled in the art.

As recognized by those skilled in the art, other information may be received by the controller 22′. The remote station 44′ may also receive information from the controller 22′, for example, a number and size of the scrubs in the vending machine, a date and time a scrub is dispensed. Of course, other information may be sent between the controller 22′ and the remote station 44′.
The remote station 44′ may include a processor 46′ and a memory 50′ coupled thereto. The processor may be configured to receive the user related information from at least one user input device 52′ wirelessly connected thereto. The processor 46′ may also be configured to receive account information, such as, a password, user preferences, a user identification, a membership identification, and credit related information from the user input device. Of course, other information may be received by the processor 46′ from the user input device 52′, as those skilled in the art will appreciate. The user input device 52′ may be a mobile wireless communications device, for example, a cellular telephone, smart phone, or tablet. The user input device 52′ may be another type of electronic device capable of communicating with the processor over the internet, for example, a laptop computer, desktop computer, or the like. In some embodiments, a Quick-Response (“QR”) code is carried by the vending machine housing 12′ that may be entered into the user input device. The user related information and account information may be stored in the memory.
The processor 46′ may be configured to perform functions in cooperation with the controller 22′ and the user input device 52′. For example, the processor 46′ may determine if the user 16′ is authorized to receive scrubs from a particular vending machine 10′. The processor 46′ may determine if credit information is sufficient and upon a determination that the credit information is sufficient, send data related to a selected sized scrub 24′ to the controller 22′ and deduct a value from the credit information. The processor 46′ may also determine the number and size of different sized scrubs 14′ carried by the vending machine housing 12′ and generate the same to a user 16. The processor 46′ may monitor and display images of various activity, for example, a user's purchase history, a vending machine's dispense history, the time and location a scrub is dispensed, the user 16 to whom a scrub is dispensed, user location over a period of time, sales related information. In some embodiments, the processor 46′ may display this information only if an account is authorized. As will be appreciated by those skilled in the art, the remote station 44′ may include a non-transitory computer readable medium that performs the functions of the processor 46′ identified above.
