Abstract

The system is designed for use in a hospital for tracking hand washing and other medical care related tasks. It includes multiple disinfectant soap dispenser devices connected to a network server that provide confirmation that caregivers are in compliance with hospital rules regarding hand cleanliness and the performance of other patient maintenance or treatment procedures. The system individually identifies each disinfectant soap dispenser device, identifies the location of the device associated with each patient and identifies each authorized caregiver or unauthorized recorded person using the device. The device identifies its location, the identity of caregiver, the time and date of use of device, and same is recorded in a network server as part of patient records.

Claims

20. A method for tracking hand washing and other tasks in a facility having multiple locations performed by a system that includes multiple devices connected to a network server, each of which devices including a microcontroller, data entry means, a display, a fingerprint reader and a disinfectant dispenser, the method comprising the following steps:

(a) registering individuals as authorized users by entering their identification information and fingerprints in the network server;

(b) registering devices by entering information as to the location of the device in the network server upon installation at the location;

(c) reading the fingerprint of individual scanned on the fingerprint reader the device and forwarding same to the network server;

(d) comparing the read fingerprint with fingerprints entered into the network server to determine if a match is present and if so;

(e) storing the user identification, location and time at the network server;

(f) sending a message to microcontroller of the device to activate the dispenser associated with device; and

(g) recording the activation of dispenser, location of associated device and time of activation in the network server.

1. A system for tracking hand washing and other tasks in a facility having multiple locations, the system comprising:

a device associated with each location, each said device comprising a fingerprint reader, a liquid dispenser, means for driving said dispenser, a microcontroller including a memory for storing the location associated with the device, means for displaying a task to be performed by an authorized user at the stored location and means for a user to enter confirmation that the displayed task has been completed; and

a network server operably connected to each said device comprising a memory containing information about authorized users, including their fingerprints, means for determining whether a read fingerprint matches a stored fingerprint and a task to be performed by a particular authorized user at the location associated with the device, means for recording confirmation entered on the device that the task has been completed, as well as the identity of the identified user and the time and date confirmation is entered.

2. The system of claim 1 wherein said displaying means includes an LCD display operably connected to said microcontroller.

3. The system of claim 1 wherein said means for entering confirmation includes a keypad operably connected to said microcontroller.

4. The system of claim 1 wherein said displaying means and the means for entering confirmation comprise a touch sensitive screen.

5. The system of claim 1 further comprising means for comparing the stored fingerprints and the read fingerprint to determine if the read fingerprint matches a stored fingerprint, indicating an authorized user.

6. The system of claim 1 wherein said driving means comprises a drive circuit connected between said dispenser and said microcontroller.

7. The system of claim 1 wherein memory comprises a non-volatile EEPROM.

8. The system of claim 1 further comprising means of connecting each of said devices with said network server.

9. The system of claim 8 wherein said connecting means comprises an Ethernet module connected between said microcontroller and said network server.

10. The system of claim 8 wherein said connecting means comprises wireless connecting means.

11. The system of claim 1 further comprising an electronic record keeping system operably connected to said network server.

12. The system of claim 1 further comprising an electronic financial record keeping system operably connected to said network server.

13. The system of claim 1 wherein said network server comprises means for accessing the list of stored tasks for an identified user to perform at the location associated with a device and means for forwarding same to said microcontroller for display by the device.

14. The system of claim 1 wherein said task comprises hand washing.

15. The system of claim 1 wherein said facility is a medical facility.

16. The system of claim 1 wherein said authorized user is a healthcare professional including a doctor, nurse, aid or other caregiver.

17. The system of claim 1 further comprising means for activating said dispenser to dispense disinfectant to an unauthorized user.

18. The system of claim 1 wherein said device comprises an enclosure comprising said fingerprint reader and said microcontroller.

19. The system of claim 18 further comprising a separate enclosure and wherein said dispenser is situated in said separate enclosure.

21. The method of claim 20 further comprising the steps of:

(h) determining the class of an authorized user;

(i) accessing the network server to identify a task to be performed by a authorized user of the determined class at the location associated with the device;

(j) sending a message from the network server to the device indicating the determined task;

(k) displaying the task message on device display;

(l) determining if confirmation of task completion is entered on device; and

, if so,

(m) recording confirmation of task completion in the network server.

22. The method of claim 20 wherein the step of sending a message from the network server to the device indicating the determined task comprises the steps of:

(p) the authorized user swiping his or her finger a second time at the fingerprint reader of the same device;

(q) determining again if the individual is authorized; and

repeating steps (i) through (m).

23. The method of claim 20 further comprising the steps of (r) comparing the read fingerprint with fingerprints entered into the network server to determine if a match is present and if not, (s) displaying a message on the device display asking if the unknown user wants liquid from the dispenser;

(t) receiving confirmation that the unknown user want liquid within a given time period and (u) activating the dispenser.

21-1. The method of claim 20 wherein the step of registering individuals comprises the steps of (n) entering the fingerprint of the individual in the network server through a fingerprint reader connected to the server and (o) entering information regarding the professional qualifications of the individual in the network server.
