Abstract
Apparatus and methods related to an underbody support for supporting a body of a being, such as during surgery to prevent contact pressure injuries. In certain embodiments, the underbody support may include one or more inflatable chambers enclosing a volume. At least one of the inflatable chambers may include one or more compression sensitive switches for monitoring the volume of the inflatable chamber, and the one or more compression sensitive switches may be located within the inflatable chamber. In some embodiments the one or more compression sensitive switches are sized to close when the said inflatable chamber is deflated to a desired residual volume.
Core Innovation
The document describes patient-securing overlays and a patient-securing draw sheet for securing a patient to an underbody support during surgery. The overlays include a sheet of fabric that is separate from the underbody support and that at least partially covers the underbody support while having an upper surface configured to contact the patient and a lower surface configured to contact the underbody support.
The fabric is at least partially coated on both the upper surface and the lower surface with three-dimensional friction enhancing elements comprising plastic or rubber. The elements on the lower surface grip the upper surface of the underbody support, and the elements on the upper surface grip at least a portion of a back of the patient, increasing a coefficient of friction and preventing the patient from inadvertently slipping off of the underbody support.
The document further provides a patient-securing draw sheet configured to be positioned over an upper surface of the patient-securing overlay for lifting a patient. The draw sheet is separate from the patient-securing overlay and includes three-dimensional friction enhancing elements in a three-dimensional raised pattern or three-dimensional raised dots, comprising plastic or rubber, configured to reduce sliding of the patient relative to the underbody support.
For a configuration in which the underbody support is secured to a surgical table and the surgical table is tilted into a head-down Trendelenburg position, the overlay is configured to resist sliding of the patient relative to the underbody support and to the surgical table, and the underbody support is configured to be coupled to the surgical table so that the sheet of fabric is indirectly attached to the surgical table.
Claims Coverage
The provided excerpt includes four independent claims, each centered on using three-dimensional friction enhancing elements on fabric sheets to resist sliding and to manage sliding risk under surgical conditions including head-down Trendelenburg.
Patient-securing overlay with three-dimensional friction enhancing elements on both sides
A patient-securing overlay comprising a separate sheet of fabric with an upper surface configured to be in contact with the patient and a lower surface configured to be in contact with an upper surface of the underbody support, both surfaces at least partially coated with three-dimensional friction enhancing elements comprising plastic or rubber, the elements being oriented so that lower-surface elements grip the upper surface of the underbody support and upper-surface elements grip at least a portion of a back of the patient to increase a coefficient of friction.
Method of restricting sliding using a fabric overlay between patient and underbody support
A method of restricting a sliding motion of a patient on an underbody support secured to a surgical table by placing a patient-securing overlay between the upper surface of the underbody support and the patient, where a separate sheet of fabric has an upper surface contacting the patient and a lower surface contacting the underbody support, is coated on both sides with three-dimensional friction enhancing elements comprising plastic or rubber oriented to grip the underbody support and grip a back of the patient, and includes positioning the patient so that the elements increase a coefficient of friction between the sheet and the underbody support.
Patient-securing overlay indirectly attached for resisting sliding during head-down Trendelenburg
A patient-securing overlay for a patient secured to an underbody support secured to a surgical table, the overlay including a separate sheet of fabric with upper and lower surfaces at least partially covered and at least partially coated on both sides with three-dimensional friction enhancing elements comprising plastic or rubber, oriented so that lower-surface elements grip the upper surface of the underbody support to increase a coefficient of friction and upper-surface elements grip a back of the patient, and the overlay being configured so that the sheet of fabric is indirectly attached to the surgical table via coupling of the underbody support, to resist sliding of the patient relative to the underbody support and to the surgical table when the surgical table is tilted into a head-down Trendelenburg position.
Patient-securing draw sheet with raised three-dimensional friction enhancing elements
A patient-securing draw sheet comprising a draw sheet configured to be positioned over an upper surface of the patient-securing overlay for lifting a patient, where the draw sheet is separate from the patient-securing overlay and includes a sheet of fabric with an upper surface configured to be in contact with the patient and a lower surface configured to be in contact with the upper surface of the patient-securing overlay, and includes three-dimensional friction enhancing elements comprising a three-dimensional raised pattern or three-dimensional raised dots of plastic or rubber configured to reduce sliding of the patient relative to the underbody support.
Across the independent claims, the core claim coverage centers on fabric-based patient-securing overlays and a patient-securing draw sheet using oriented three-dimensional friction enhancing elements to grip both the underbody support and the patient’s back, including configurations that resist sliding during head-down Trendelenburg via an underbody-support coupling to the surgical table.
Stated Advantages
Resists sliding of the patient relative to the underbody support and, in the Trendelenburg configuration, relative to the surgical table as well.
Increases a coefficient of friction between the sheet of fabric and the underbody support.
Prevents the patient from inadvertently slipping off of the underbody support.
Supports the patient during surgery.
Reduces sliding of the patient relative to the underbody support when using the patient-securing draw sheet.
Documented Applications
Surgery in which a patient is secured to an underbody support and wherein the surgical table may be tilted into a head-down Trendelenburg position.
