Such a mount interface provides rapid and secure locking of a latch to the latching assembly. ## Claims ### Claim 1 A mount interface comprising: a latch; a latching assembly configured to receive the latch so as to lock the latch at a set position with respect to the latching assembly, wherein the latching assembly includes a housing provided with an irregular orifice configured to receive the latch; a first plug disposed in the housing so that a first portion of the irregular orifice overlies the first plug; and a second plug disposed in the housing adjacent the first plug so that a second portion of the irregular orifice overlies the second plug, wherein the second portion is adjacent the first portion, wherein the irregular orifice is keyhole shaped with at least a circular portion contiguous with an elongated portion, and the circular portion overlies both the first plug and partially the second plug and the elongated portion overlies partially the second plug and not the first plug. ### Claim 2 (depends on 1) The mount interface according to claim 1, wherein when the latch is locked at the set position, the latch is in contact with the first plug and the second plug. ### Claim 3 (depends on 1) The mount interface according to claim 1, wherein the first plug and the second plug are moveable in a transverse direction parallel to one another. ### Claim 4 (depends on 3) The mount interface according to claim 3, wherein the first plug and the second plug are each spring-biased towards an external surface of the housing. ### Claim 5 (depends on 4) The mount interlace according to claim 4, wherein when the latch is disengaged from the latching assembly the first plug and the second plug are each spring-biased into a position in which at least one surface of the first plug and at least one surface of the second plug are substantially flush with the external surface of the housing. ### Claim 6 (depends on 5) The mount interface according to claim 5, wherein when the at least one surface of the first plug and the at least one surface of the second plug are substantially flush with the external surface of the housing, then the first plug abuts the second plug. ### Claim 7 (depends on 6) The mount interface of claim 6, wherein when the latch is locked in the set position, then the first plug and the second plug do not abut one another. ### Claim 8 (depends on 1) The mount interface of claim 1, further comprising a non-linear link connected at one end to the first plug and pivotally connected to the housing. ### Claim 9 (depends on 8) The mount interface of claim 8, wherein the non-linear link is connected at a second end to a release button so that when pressure is exerted on the release button, the release button is depressed towards an interior of the housing and the non-linear link pivots so as to move the first plug away from the first portion of the irregular orifice. ### Claim 10 (depends on 9) The mount interface of claim 9, wherein the non-linear link comprises a linear portion connected to a minor bend portion by a major bend portion. ### Claim 11 (depends on 1) The mount interface of claim 1, wherein the latch is cylindrical and includes a neck portion having a diameter that is smaller than a diameter of a head portion that is connected to the neck portion, and wherein the diameter of the head portion is smaller than a diameter of the circular portion of the irregular orifice and the diameter of the head portion is larger than a maximum width of the elongated portion of the irregular orifice. ### Claim 12 (depends on 1) A heart-lung machine comprises the mount interface according to claim 1, comprising: a frame, and wherein the mount interface is connected to the frame. ### Claim 13 (depends on 12) The heart-lung machine according to claim 12, wherein the latch is connected to the frame and the latching assembly is connected to a medical device, or wherein the latch is connected to the medical device and the latching assembly is connected to the frame. ### Claim 14 (depends on 13) The heart-lung machine according to claim 13, wherein the medical device is selected from the group consisting of a centrifugal blood pump, a venous reservoir, an oxygenator, a venous clamp and a medical graphical user interface display apparatus.
