Abstract

A computerized medication dispensing cart and system for dispensing prepackaged unit-dose medications to a patient in a medical facility including a computer system on the cart for storing medication information regarding each patient provided by a pharmacy and a plurality of dispensers on the cart that automatically dispense prepackaged unit dosages of prescribed medications at the request of nursing personnel while making rounds. A separate dispenser on the cart is used to dispense each type of medication. An input device, such as a touch screen monitor, is mounted on the cart to permit nursing personnel to access the medication information regarding the patient and to request that the cart dispense the prescribed medications. A detector is mounted on each dispenser that detects the administration of the medications to the patient and records the time and date that the medications were administered.

Claims

1. A computerized unit dose medication dispensing cart for use in a medical facility comprising:

a cart for transporting prepackaged unit dose medications;

an input device mounted on said cart for generating a request signal to initiate the dispensing of the prepackaged unit dose medications for a patient;

a computer system mounted on said cart and coupled to the input device, the computer system having memory means for storing medication information relating to the patient and means for generating a dispense signal in response to the request signal;

a plurality of dispensing means mounted on said cart and coupled to said computer system, each dispensing means including a motor coupled to a plurality of rollers, the motor rotating the rollers in response to the dispense signal from said computer system, the rollers advancing a prepackaged unit dosage of a medication over the rollers and through a slit in the dispensing means from a stack of prepackaged unit dose medications stored in the dispensing means, each prepackaged unit dose medication dispensed through the slit being separable from the stack, said computer system transmitting the dispense signal only to the dispensing means dispensing a prepackaged unit dosage of a medication to be dispensed to the patient based on the medication information relating to the patient stored in said memory means; and

detection means mounted on said dispensing means and coupled to said computer system for detecting the dispensing of the prepackaged unit dose medications from said dispensing means, the computer system recording in the memory means that the dispensing of the prepackaged unit dose medication to the patient has occurred.

2. The computerized unit-dose medication dispensing cart of claim 1 wherein said plurality of dispensing means further comprises means for simultaneously dispensing a prepackaged unit dosage of each of the medications ordered for a patient from a pharmacy for administering by a nurse to a patient while the nurse is making rounds.

3. The computerized unit-dose medication dispensing cart of claim 1 wherein said plurality of dispensing means further comprises means for sequentially dispensing a prepackaged unit dosage of each of the medications ordered for a patient from a pharmacy for administering by a nurse to a patient while the nurse is making rounds.

4. The computerized unit-dose medication dispensing cart of claim 1 wherein said input device comprises a touch screen monitor.

5. The computerized unit-dose medication dispensing cart of claim 4 wherein said input device displays a digitized profile of each patient with the medication information of the patient to assist the nurse in verifying the identification of the patient.

6. The computerized unit-dose medication dispensing cart of claim 1 wherein said input device comprises a display monitor equipped with a mouse.

7. The computerized unit-dose medication dispensing cart of claim 1 wherein said input device comprises a display monitor equipped with a keyboard.

8. The computerized unit-dose medication dispensing cart of claim 1 wherein said computer system further comprises a communications port for connecting a modem to establish a two-way link with a pharmacy to transmit and receive medication information relating to a patient.

9. The computerized unit-dose medication dispensing cart of claim 1 wherein said computer system further comprises means for recording in the memory means information input by a nurse into the input device relating to a patient'"'"'s reaction to the administering of a medication.

10. The computerized unit-dose medication dispensing cart of claim 1 wherein said cart further comprises a plurality of storage drawers for storing medical supplies and medications that cannot be dispensed by said dispensing means.

11. A method for dispensing prepackaged unit-dose medications to a patient for use in a medical facility comprising:

transporting prepackaged unit-dose medications on a cart;

storing medication information relating to the patient in a computer system mounted on said cart;

generating a request signal to initiate the dispensing of prepackaged unit-dose medications for the patient from an input device mounted on said cart;

receiving the request signal at said computer system;

generating a dispense signal at said computer system in response to the request signal;

transmitting the dispense signal from said computer system to a plurality of dispensers storing a plurality of prepackaged unit dosages of a medication to be dispensed to the patient;

receiving the dispense signal at each of said plurality of dispensers;

rotating a plurality of rollers located within each of said plurality of dispensers in response to the dispense signal to advance a prepackaged unit dosage of a medication over the rollers and through a slit in each dispenser from a stack of prepackaged unit dose medications stored in each dispenser; and

detecting that the prepackaged unit-dose medications were dispensed from each dispenser.

12. The method of claim 11 further comprising the step of displaying a digitized profile of the patient from the input device to assist in verifying the patient'"'"'s identity.

13. The method of claim 11 further comprising the step of recording information relating to a patient'"'"'s reaction to the administering of a medication.

14. The method of claim 11 further comprising the step of connecting a modem to said computer system to establish a two-way link with a pharmacy.

15. The method of claim 14 further comprising the step of transmitting to the pharmacy information relating to the time and date that the prepackaged unit-dose medications were administered to the patient.

16. The method of claim 15 further comprising the step of receiving from the pharmacy information relating to medication orders developed by the pharmacist for the patient.
