A vacuum system for applying vacuum to the body cavity of a patient where a flow switch is provided that is located upstream of a vacuum regulator that can be adjusted to establish the level of vacuum desired to be applied to the patient. The flow switch provides an easy device for the caregiver to activate to fully and positively occlude the vacuum line to the patient. In one embodiment, the flow switch is constructed integral with a regulator having an rotatable actuator having a knob that is rotated to adjust the level of vacuum to the patient such the a caregiver can simply push the actuator knob inwardly to occlude the flow in the patient line and thereafter rotate the actuator knob to establish the desired level of vacuum to the patient.

An infant incubator tilt mechanism is disclosed that allows infinite adjustment of the tilt angle of the infant mattress within certain limits. The mechanism includes a bent rod positioned within the infant incubator itself and underlying the infant bed and which has an offset portion that engages a bed lifter. As the bent rod is rotated about an axis, the bent rod moves the bed lifter to raise and/or lower the infant bed. One end of the bent rod extends outwardly to the exterior of the infant compartment and is rotatable by an exterior mechanism having a lead screw that is rotated by the operator to cause lateral movement of a link mechanism along an axis at about ninety degrees to the axis of rotation of the bent rod. The lateral movement of the link is again translated into rotational movement and connects to the bent rod to translate that rotational movement to the bent rod. The entire tilt mechanism is readily removable so as to be easily cleaned.

An infant care apparatus such as an incubator or infant warmer having a mattress for supporting the infant on an infant platform that can, at times, by fully rotated 360 degrees to obtain full access to the infant. In the incubator, a translation platform can be slid into and out of the infant compartment and the mattress tray is pivoted to that translation platform so as to rotate at a pivot point that connects the mattress tray to the translation platform. Accordingly, when all of the doors of the infant incubator are in the closed position, the mattress tray is constrained from rotational movement but that mattress tray can be rotated a full 360 degrees whenever both doors are open or when the translation platform has been moved to a position at least partially exterior of the infant compartment. In all, the apparatus provides easy and convenient access to the infant for carrying out procedures on the infant while it is still supported by the infant care apparatus.

An infant warming apparatus that functions both as an infant incubator as well as an infant warmer. The apparatus has a heater that moves vertically with respect to an infant support during the change in function between an infant incubator and infant warmer. A powered motive system, such as an electric motor, powers the movement of the heater between its upper and its lower positions. The heater also has a door or doors that are open when the heater is in it upper position so that the heater can direct energy toward the infant to warm the infant when acting as an infant warmer. When closed, the doors isolate the heater to prevent the inadvertent touching of the heater by the infant or attending personnel. A safety interlock system is provided that prevents the heater from being activated unless it is in its upper position and the door or doors are fully open. In addition, the interlock system also monitors the downward movement of the heater and discontinues that downward movement if the heater reaches a predetermined position and the door or doors are still in the open position.

A powered motive system, such as an electric motor, powers the movement of the heater between its upper and its lower positions. The heater also has a door or doors that are open when the heater is at or nearing the upper position so that the heater can direct energy toward the infant to warm the infant when acting as an infant warmer. The doors close at or shortly after the heater commences movement to the lower position. When closed, the doors isolate the heater to prevent the inadvertent touching of the heater by the infant or attending personnel and prevents the further radiating of infrared energy towards the infant. The mechanism operates automatically without any reminder to the user or action by the user. A vent is also provided in the heater housing that ventilates the housing when the heater is in its upper position and closes to confine the housing when the heater is in its lower position.

An infant care center or infant care warmer having as it source of heat, a radiant heater that includes a reflector in the shape of a quadratic surface of revolution consisting of a paraboloid, an ellipsoid or a hyperboloid. The shape allows the heater to be positioned at the head of the infant care apparatus and out of the way of the attending personnel and yet deliver sufficient heat to provide warmth to the infant. An infrared energy emitter is positioned at substantially the focal point of the geometric configuration of the reflector to provide radiant energy to be reflected toward an infant resting on a planar surface underneath the heater. While out of the way of the infant and the attending personnel, the radiant heater provides a generally uniform footprint of heat to the infant.

An infant care apparatus having a door latching mechanism that provides a positive latching of a door to the hood of the apparatus. The mechanism has a door latching assembly that is affixed to the door and which is latched to a floating catch housing that is affixed to the hood in a manner that the floating catch housing is vertically movable with respect to the hood. When the door is moved into its closed, latched position, the door latching assembly vertically aligns the floating catch housing so that a movable latch member is correctly oriented with respect to latch openings in the floating catch housing so that the movable catch member can enter the latch openings sufficiently to assure a positive, secure latch therebetween.

A needle valve including a deformable seal positioned between the distal end of the needle and a hard, mechanical seat between the needle and the valve housing. The deformable seal is able to seal around the movable needle but is protected from serious deformation by the hard mechanical seat that is located so as to prevent the needle from entering the deformable seat beyond a predetermined amount. Thus the deformable seal does not extrude due to the entrance of the needle and wear is reduced.

A heated humidifier for an infant incubator wherein the flow of air through the humidifier that picks up water vapor from the surface of the water is controlled in response to the temperature of the heater used to heat the water. In the preferred embodiment, the heater is an active heater located above the surface of the water and includes an extruded heat exchanger that depends downwardly from the heater to below the level of the water. A thermal actuator is located in good heat transfer association with the extruded heat exchanger at a point above the surface of the water and that thermal actuator controls the position of a valve in the outlet of the humidifier.

An incubator having a mattress tray that underlies and supports an infant. The mattress tray is movable from a first position where it is entirely within the controlled atmosphere of the infant compartment to a second position outside that infant compartment and when moved to the second position, a warm flow of air is provided to warm the infant. The outside position of the mattress thereby allows considerable access to the infant to carry out procedures by attending personnel that would not be possible within the confined infant compartment and yet the invent is warmed by the flow of warm air.
