Abstract

Claims (33)

1 . A transport system for transporting items between sterile and non-sterile environments, comprising:

a transport device that has opposite first and second ends and opposite first and second sides;

a wheel base assembly separate from the transport device, the wheel base assembly comprising a platform and a plurality of wheels attached thereto, the platform being configured to slidably receive and support the transport device, and at least one wheel of the plurality of wheels has a braking mechanism configured to stop the respective wheel;

a locking mechanism that releasably couples the transport device and the wheel base assembly; and

a cleaning device at the wheel base assembly configured to clean a surface of the transport device as the transport device is loaded onto or unloaded from the wheel base assembly.

2 . The transport system of claim 1 , wherein the first end of the transport device includes a handle.

3 . The transport system of claim 1 , wherein the cleaning device is a sponge or a scraping device.

4 . The transport system of claim 1 , wherein one or both of the first and second sides has a guide rail for guiding the wheel base assembly onto the platform.

5 . The transport system of claim 4 , wherein one or both of the first and second sides of the transport device has one or more guide wheel configured to engage the guide rail.

6 . The transport system of claim 1 , wherein the transport device and wheel base assembly are formed of autoclavable materials.

7 . The transport system of claim 1 , wherein said locking mechanism fixedly couples the transport device to the wheel base assembly whereby the transport device is fixed with respect to the wheel base assembly.

8 . A transport system for transporting items between sterile and non-sterile environments, comprising:

a transport device that has opposite first and second ends and opposite first and second sides;

a wheel base assembly separate from the transport device, the wheel base assembly comprising a platform and a plurality of wheels attached thereto, the platform being configured to slidably receive and support the transport device, and at least one wheel of the plurality of wheels has a braking mechanism configured to stop the respective wheel; and

a locking mechanism that releasably couples the transport device and the wheel base assembly, wherein the locking mechanism includes a spring biased rod coupled to the transport device and a corresponding opening in the wheel base assembly configured to receive the rod when aligned therewith.

9 . A transport system for transporting items between sterile and non-sterile environments, comprising:

a transport device that has opposite first and second ends and opposite first and second sides;

a wheel base assembly separate from the transport device, the wheel base assembly comprising a platform and a plurality of wheels attached thereto, the platform being configured to slidably receive and support the transport device, and at least one wheel of the plurality of wheels has a braking mechanism configured to stop the respective wheel; and

a locking mechanism that releasably couples the transport device and the wheel base assembly;

a rotatable actuation mechanism associated with the braking mechanism, the rotatable actuation mechanism is configured to move between an open position at which no stopping force is applied by the braking mechanism, and a braking position at which the actuation mechanism causes the braking mechanism to apply a stopping force, wherein the rotatable actuation mechanism includes a handle at the first end of the transport device that extends upward above the platform of the wheel base assembly.

10 . The transport system of claim 9 , wherein the rotatable actuation mechanism includes a horizontal bar that is coupled to a handle and extends horizontally between at least two braking mechanisms.

11 . A transport system for transporting items between sterile and non-sterile environments, comprising:

a transport device;

first and second wheel base assemblies separate from the transport device, each of the first and second wheel base assemblies comprising a platform and a plurality of wheels attached thereto, the platform being configured to slidably receive and support the transport device, and at least one wheel of the plurality of wheels having a braking mechanism;

a locking mechanism that releasably couples the transport device to one of the first and second wheel base assemblies; and

a cleaning device at the first wheel base assembly configured to clean a bottom surface of the transport device when loading and unloading the transport device.

12 . The transport system of claim 11 , wherein the platform of each of the first and second wheel base assemblies has a flat and smooth sliding surface for loading and unloading the transport device.

13 . The transport system of claim 11 , wherein the first and second wheel base assemblies are identical.

14 . The transport system of claim 11 , wherein the first wheel base assembly is in the sterile environment and the second wheel base assembly is in the non-sterile environment.

15 . The transport system of claim 14 , wherein the first wheel base assembly is formed of autoclavable material.

16 . The transport system of claim 11 , wherein the first wheel base assembly has a stop tab coupled to another end of the wheel base assembly opposite the cleaning device that extends vertically above the platform, wherein the stop tab is configured to prevent the transport device sliding past the stop tab.

17 . The transport system of claim 11 , wherein the locking mechanism includes a spring biased rod coupled to the transport device and a corresponding opening in one of the first and second wheel base assemblies, the opening is configured to receive the rod when aligned therewith.

18 . The transport system of claim 11 , wherein each of the first and second wheel base assemblies includes a rotatable actuation mechanism associated with the braking mechanism, the rotatable actuation mechanism is configured to move between an open position, at which no stopping force is applied by the braking mechanism, and a braking position, at which the actuation mechanism causes the braking mechanism to apply a stopping force.
