The EggNest Protect is an integrated scatter radiation protection shielding system. The intended purpose of the EggNest Protect is to protect all healthcare workers in the x-ray procedure room from scatter radiation during medical procedures employing imaging in the range of 70-100 keV energy levels [1], as well as to limit radiation exposure to the head of the patient during cardiac procedures.
The Base Platform is covered with a detachable vinyl-covered mattress that provides for patient comfort. See Figure 1 for an image of the EggNest Protect Base System.

Figure 2: Side Flex Shield Connectors The Side Flex Shields are designed to be flexible in order to move with the motion of the x-ray gantry to allow for imaging angles. The shields contain semi-flexible stays that maintain the shape of the shielding and prevent them from impinging on the x-ray emitter and blocking the x-ray images of the patient.

Figure 5: Side Flex Shields retracted Using the buckles on either end of the shield, they can be buckled to themselves to bundle the shielding and prevent it from moving during the procedure as shown in Figure 6. Figure 6: Retracted shields buckled When the need for steep angled imaging is complete, the shields can be unbuckled and returned to their fully deployed configuration to provide maximum scatter radiation protection.
Figure 7: Opening radial drawer Head Flex Shields The Head Flex Shields are also vinyl-covered curtains that contain material that has the radiation- shielding equivalent of 0.5mm lead. These shields are mounted to a base plate that is designed to mount to connector recesses in the base system upper half as shown in Figure 8.
Arm Positioning System The Arm Positioning System is designed to hold the right arm of the patient during procedures that require radial, ulnar, brachial or axillary access. This system is designed to reside upon the rail of the upper base system as shown in Figure 9 using the channel components on the underside of the system.
The Arm Positioning System has an optional Arm Holder that can be used to support the wrist of the patient in an extended position to facilitate radial artery access. This Arm Holder latches into the base of the arm positioning system as shown in Figure 11. If the Arm Holder is not needed for a procedure, it can be removed and the patient arm placed directly on the Arm Positioning Base.
Figure 13: Side Flip Shield Placement The shielding flip board consists of x-ray shielding material that is laminated between thin sheets of carbon fiber. The jam board is placed under the patient mattress through a slot in the upper base table rail and can be used in conjunction with other system components such as the Arm Positioning System.
Designed to ride along the inner rail on the patient right side of the EggNest Protect system as shown in Figure 17, they provide the greatest protection when fully extended and moved up into the armpit of the patient under the sterile drape.
EggNest Protect Base System. This mattress component is mounted to the table in the x-ray laboratory in a position caudal to the end of the EggNest Protect Mattress and can be provided in two different lengths depending on the available space on the lab table.
Installation of the EggNest™ Protect System The EggNest Protect is designed to rest on a standard x-ray table by replacing the OEM patient mattress. Step 1: Prepare the X-ray table Remove existing X-ray table mattress and thoroughly clean the table surface.
Step 4: Place Mattress Topper on top of Base Platform Once the Base Platform is secured on the x-ray table, place the Mattress on the Base Platform.Ensure that the Velcro strips on the underside of the Mattress align with the Velcro strips on the Base Platform.
Insert the connector stop on the head end of the tube and attach the distal latch mechanism as shown in Figure 25. Figure 25: Connector and distal latch Step 6: Attach the Head Flex Shields The Head Flex Shields are installed by aligning the tabs on the Head Flex Shield hardware with the slots in the head of the Base System and dropping them into place.
Step 8: Mount the Clear Spot Shield The Clear Spot Shield is mounted to the EggNest Protect by inserting the cylindrical base of the pole into the receiver mount found on the slide rail attached to the patient left side of the system as shown in Figure 29.
Figure 30: Side Flip Shield Insertion These shields can be flipped down for patient transfer and back up for clinical use, or removed from the table for patient transfer if desired. Figure 31: Side Flip Shield articulation Step 10: Install the Head Flip Shields The Head Flip Shields are removable shields that are placed around the head of the patient.
The Head Flip Shields at the sides of the patient head are placed by aligning the guide pins into the receiving holes on the left- and right-side rails. These shields may also be rotated up to provide protection around the sides of the patient head during procedures. See Figures 33 and 34.

There are two anchor strap loops installed in the Base System beneath the patient mattress.These loops are intended for use to install a Patient Strap based on hospital recommendations. Egg Medical provides a Velcro strap that can be used for securing the patient to the table by threading the strap through the loops as shown in Figure 38.
6. If loading from a patient bed, slide the bed next to the EggNest Protect a. Using a sliding board or hover mat, move the patient from the bed to the EggNest Protect b. Take care that neither the patient bed or the EggNest Protect move as the patient could fall through the gap 7.
6. Rotate the Clear Spot Shield back into ready position Operation During Procedure In general, the EggNest Protect operates passively during the procedure. The c-arm x-ray gantry can be rotated to achieve the desired radiographic views. The x-ray gantry may contact the EggNest Protect Flex Shields when rotated out of the PA projection.
Patient Loading Like all patient transfers, transferring a patient from a bed or gurney to the EggNest Protect has a risk of patient injury due to falling or pinching during transfer. To minimize the risk of transfer, use care in patient movement and minimize the gap between the EggNest Protect and the transfer device.
If the Flex Shielding or another component of the EggNest Protect is in contact with the x-ray tube housing, move the table or the x-ray gantry in order to disengage the systems. If the Flex Shielding is stuck on the c-arm, gently lift the Flex Shielding to disengage. In any case, DO NOT force the EggNest Protect or c-arm components past each other.
The carbon fiber base system is made from materials similar to those used for many x-ray tables. The vinyl mattress is durable and cleanable, though it may become discolored if cleaned with an unapproved cleaning agent. The EggNest Protect should be cleaned between uses with one of the following cleaning solutions: Cleaning Agent Manufacturer...
Product Disposal If the EggNest Protect is to be removed from service at the end of useful life, it can be disposed in normal waste streams with the exception of the Clear Spot Shield which must be returned to Egg...
