Abstract

An autonomous medical waste collection assembly. A base supports a waste canister in fluid communication with a manifold receiver, and a suction pump. A controller is in electronic communication with a powered wheel and configured to transmit a movement signal for a motor to power the powered wheel to move the assembly along a floor surface. The assembly may be operable in an autonomous mode in which the powered wheel automatically moves the assembly along the floor surface, and a manual mode in which resistance from the powered wheel is negated to provide for manual movement of the assembly. The controller may be further configured to steer the assembly based on a current location input signal, and a disposal location input signal from a locator network within the medical facility that is indicative of a location of a disposal station.

First claim

The invention claimed is:

1. An autonomous medical waste collection assembly for collecting medical waste within a medical facility, the autonomous medical waste collection assembly comprising:
a base;
wheels supporting the base with at least one of the wheels being a powered wheel configured to be powered by a motor;
a waste collection unit supported by the base and comprising a manifold receiver configured to removably receive a manifold to which a suction tube is couplable, a waste canister in fluid communication with the manifold receiver, and a suction pump in fluid communication with the waste canister and configured to draw medical waste from a patient through the suction tube and the manifold to be collected in the waste canister; and
a controller in electronic communication with the powered wheel and configured to transmit a movement signal for the motor to power the powered wheel to move the autonomous medical waste collection assembly along a floor surface.

2. The autonomous medical waste collection assembly of claim 1 , wherein the controller is further configured to initiate a waste disposal protocol in which the controller operates the powered wheel to move the autonomous medical waste collection assembly along the floor surface to be coupled with a disposal station for emptying the waste canister.

3. The autonomous medical waste collection assembly of claim 2 , further comprising a waste sensor in communication with the controller and configured to sense an amount of the medical waste contained within the waste canister, and wherein the controller is further configured to initiate the waste disposal protocol based on the amount of the medical waste within the waste canister.

4. The autonomous medical waste collection assembly of claim 2 , further comprising memory in electronic communication with the controller and storing a disposal schedule of one or more times to initiate the waste disposal protocol, and wherein the controller is configured to operate the powered wheel according to the disposal schedule.

5. The autonomous medical waste collection assembly of claim 4 , wherein the controller is further configured to not initiate the waste disposal protocol according to the disposal schedule if a state of the autonomous medical waste collection assembly is indicative of an ongoing surgical procedure.

6. The autonomous medical waste collection assembly of claim 4 , wherein the disposal schedule is configured to be wirelessly received via a hospital network of the medical facility to be stored on the memory.

7. The autonomous medical waste collection assembly of claim 4 , wherein the memory stores instructions for a quick docking mode in which the waste canister is cleaned by the disposal station for a first duration, and an extended docking mode in which the waste canister is cleaned by the disposal station for a second duration greater than the first duration, and wherein the controller is configured to facilitate operation of the disposal station in one of the docking modes according to the disposal schedule.

8. The autonomous medical waste collection assembly of claim 1 , wherein the controller is further to receive indication of a state of the suction pump, and prevent operation of the powered wheel if the state is indicative of an ongoing surgical procedure.

9. The autonomous medical waste collection assembly of claim 1 , wherein the manifold receiver comprises a manifold sensor in electronic communication with the controller and configured to detect absence or presence of the manifold, and wherein the controller is further configured to operate or prevent operation of the powered wheel based on data received from the manifold sensor.

10. The autonomous medical waste collection assembly of claim 1 , further comprising a battery in communication with the controller, wherein the controller is further configured to initiate a charging protocol in which the controller operates the powered wheel to move the autonomous medical waste collection assembly along the floor surface to be coupled with a charging station to charge the battery, and not initiate the charging protocol if a state of the autonomous medical waste collection assembly is indicative of an ongoing surgical procedure.

11. The autonomous medical waste collection assembly of claim 10 , memory in communication with the controller and storing instructions, and wherein the controller is configured to facilitate operation of a disposal station to simultaneously perform a waste disposal protocol and the charging protocol according to the instructions.

12. The autonomous medical waste collection assembly of claim 10 , further comprising memory in communication with the controller and storing a charging schedule of one or more times to initiate the charging protocol, and wherein the controller is configured to operate the powered wheel according to the charging schedule.

13. The autonomous medical waste collection assembly of claim 1 , wherein the controller comprises a wireless module configured to be arranged in wireless communication with locator sensors of the medical facility, wherein the controller is configured to control the powered wheel to steer the autonomous medical waste collection assembly based on data received from the locator sensors.

14. The autonomous medical waste collection assembly of claim 1 , wherein the autonomous medical waste collection assembly is operable in an autonomous mode in which the powered wheel automatically moves the autonomous medical waste collection assembly along a floor surface, and a manual mode in which resistance from the powered wheel is negated to provide for manual movement of the autonomous medical waste collection assembly along the floor surface.

15. An autonomous medical waste collection assembly for collecting medical waste within a medical facility, the autonomous medical waste collection assembly comprising:
a base;
wheels supporting the base with at least one of the wheels being a powered wheel configured to be powered by a motor;
a waste collection unit supported by the base and comprising a waste canister for receiving medical waste from a patient, and a suction pump in fluid communication with and configured to draw suction on the waste canister; and
a controller configured to operate the autonomous medical waste collection assembly is operable in an autonomous mode in which the powered wheel automatically moves the autonomous medical waste collection assembly along a floor surface, and a manual mode in which resistance from the powered wheel is negated to provide for manual movement of the autonomous medical waste collection assembly along the floor surface.

16. The autonomous medical waste collection assembly of claim 15 , further comprising a clutch mechanism coupled to the powered wheel and in communication with the controller, wherein the clutch mechanism is configured to be operated by the controller in the manual mode to operably decouple from the powered wheel.

17. The autonomous medical waste collection assembly of claim 15 , further comprising a lift mechanism coupled to the powered wheel and in communication with the controller, wherein the lift mechanism is configured to be operated by the controller in the manual mode to move the powered wheel away from the floor surface to provide for the manual movement of the autonomous medical waste collection assembly.

18. An autonomous medical waste collection assembly for collecting medical waste within a medical facility that includes a disposal station, the autonomous medical waste co
