Abstract

Sturdily mounting a disposable medical device by rotatably attaching a back plate to a back brace, biasing the back plate toward the medical device and employing a camming means on the back plate cooperating with a tab on the device to rotate the plate away from the device as the device is initially slid onto the mount and to return the plate to lock the device in place when the device is slid fully onto the mount.

Claims

1. A mount for supporting a medical device, said mount comprising:

a brace member for supporting a medical device placed alongside thereof,

a horizontal track on said brace member for cooperating with a horizontal lip on said device to guide said device as it is slid onto said mount, said track defining an insertion direction,

a back plate rotatably attached to a shaft which is attached to said brace member, whereby rotation of said back plate about the longitudinal axis of said shaft is allowed, said plate being rotatable away from said device from a locking position to an insertion position, said back plate including a gripping portion to allow manual rotation of said plate,

means for biasing said back plate toward said medical device, said means being operably attached to said back plate,

a stop member attached to said brace member for stopping rotation of said back plate toward said medical device beyond said locking position, and

camming means on said back plate including

a first surface inclined with respect to said insertion direction when said back plate is in said locking position for cooperating with a tab on said medical device to rotate said back plate away from said device into said insertion position as said device is slid onto said mount and

a second surface substantially perpendicular to said insertion direction when said back plate is in said locking position, said second surface cooperating with said tab to allow said biasing means to return said back plate to said locking position after said tab passes said first surface, thereby locking said device in place when said device is fully slid onto said mount.

2. The mount of claim 1 further comprising a tubular fluid coupling for receiving internally a tubular fitting extending from said device and for providing support for said device when said device is slid onto said mount.

3. The mount of claim 1 wherein said first surface is the inclined surface of a ramp portion on said backplate and the second surface includes the inner wall of a groove in said ramp portion.

4. The mount of claim 1 wherein said back plate is rotatable about a vertical axis.

5. The mount of claim 1 wherein said means for biasing said back plate toward said medical device causes said back plate to snappably engage said tab when said device is fully slid onto said mount.

6. The mount of claim 1 wherein said back plate further comprises a lever for acting against said tab to initiate movement of said device out of said mount when said back plate is rotated away from said device.

7. The mount of claim 6 wherein said mount further comprises a tubular fluid coupling for receiving a tubular fitting extending from said device, said coupling having an internal O-ring for sealing between said coupling and said fitting and said lever providing enough force to overcome the resistance said O-ring and coupling impart when removing said device from said mount.

8. The mount of claim 1 wherein said horizontal track has a horizontal grooved portion for engaging said lip of said medical device and thereby providing added support for said device.
