FIELD OF THE INVENTION
The present invention relates to a pad assembly, system, kit, and method for maintaining a patient's position during a medical procedure on a support table and, more particularly, to a surgical patient positioner pad system secures and holds the body of the patient in Trendelenburg, reverse Trendelenburg, and/or Fowler's position during a surgical procedure.
BACKGROUND OF THE INVENTION
Conventional patient positioner systems for surgical procedures that incline the support table may injury nerves, skin and other trauma to the patient, e.g. in Trendelenburg, reverse Trendelenburg, and/or other positions. Table inclinations straps are used across the patient's chest to restrain the torso of the patient; however, straps have disadvantages in obstructing ventilation and breathing and may cause pressure injury to nerves, skin, and other trauma injurious to the patient. A headrest may further be used in conjunction with conventional positioning system at additional cost to the patient positioning product.
Conventional Trendelenburg positioner systems also may use a foam pad that contours to the body (e.g. foam, closed-cell foam, memory foam) and straps prevent patient sliding thereby increasing the cost of manufacture and medical waste. Certain pad constructions can have disadvantages by not draining fluids that can lead to further complications such as trap moisture which can place patients at risk for skin maceration, skin tears, bed sore, pressure ulcer, decubitis ulcer and other hospital-acquired pressure injuries (HAPIs). Conventional Trendelenburg positioning pad systems have further disadvantages due to numerosity of parts, sterility, comfort, disposability, waste generated per procedure, and associated manufacturing costs. Consequently, there is a long-felt need for a positioner system for a support table with a lower cost and simplified construction utilizing a disposable drape that operably connects to a patient to the support table pad and a pad assembly with fluid channels for holding the patient during surgical procedures.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an apparatus, system and method to secure a patient on a support table in a desired position that is maintained throughout the duration of the surgical procedure.
It is an object of the present invention to provide a reusable article of manufacture of a support table pad, for operably connecting to a patient positioning system that maintains a patient in a desired position on the support table.
It is an object of the present invention to provide an article of manufacture of a drape and/or sheet, for operably connecting to the support table pad to a patient positioning system that maintains a patient in a desired position on the support table.
It is an object of the present invention to provide an article of manufacture of a patient positioning system having a patient pad having a loop fabric and/or loop foam for operably connecting to hook portions on a drape or sheet that operably connects to a support table pad to maintain a patient in a desired position on the support table.
