A system for securely positioning a cervical spine during surgery includes a donut-shaped frame to receive and hold a patient's head, straps integrated into the donut-shaped frame to securely hold a patient's head within the harness at least one of a patient's chin and forehead, a rubber bladder can integrated with the harness locatable beneath a patient's neck, and a pump to provide air into the rubber bladder. Air pumped into the rubber bladder by the pump can cause a patient's neck to be lifted into an arch in preparation for and during cervical spine surgery. A release valve can be provided to release air from the rubber bladder and lower a patient's neck during and after surgery. Rods can be integrated into the donut-shaped frame at each side of the rubber bladder. The rods can affix the harness to an operating table.

One embodiment of the present invention is directed to a convertible chair-to-table apparatus configured for reversible use. The apparatus may have a headrest on the leg board of the chair to enable a patient to use the chair with the patient's torso on the leg board. The invention is also directed to a method of using the apparatus by moving a patient's torso between the leg board and the back board of the apparatus.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal while performing CPR by repeatedly compressing the chest. The method includes elevating the brain within a time period selected to be slow enough to permit a sufficient amount of blood to flow to the brain throughout the elevation time period. The method also includes regulating the intrathoracic pressure of the individual while performing CPR. The performance of chest compressions is stopped and after stopping the performance of chest compressions, the head, heart, and shoulders are promptly from the final elevation angle within a timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered.

Disclosed herein are system, method, and computer program product embodiments a 6 degree-of-freedom (6DoF) correction trajectory in order to compensate movement of a treatment target in a patient supported by a patient support end-effector. An embodiment operates by receiving a starting end-effector position, a starting clinical target position, and a target destination position. The target destination position corresponds to a position in space receiving targeted treatment from a treatment delivery device. The embodiment determines a destination end-effector position in 6DoF associated with the end-effector that would cause the target to be positioned on the target destination position. A trajectory is calculated between the starting end-effector position and the destination end-effector position. The embodiment transmits, to a mechanical device controlling movement of the end-effector, one or more signals causing the end-effector to move from the starting end-effector position to the destination end-effector position along the determined trajectory.

The present invention relates to an immobilization mask comprising a first layer comprising a low temperature thermoplastic material, the first layer having a first side and a second side; at least one dimensionally stable attachment section connected to the first layer; and at least one deformable molding member connected to the first side or to the second side of the first layer. The present invention also relates to a method of immobilizing a patient's body part, comprising the steps of applying an immobilization mask comprising a first layer having a low temperature thermoplastic material and at least one dimensionally stable attachment section connected to the first layer, wherein at least one deformable molding member is placed between the first layer and the patient's head; and molding the first layer tightly to the patient's head and to the molding member.

An OR table disposable cover includes a sheet, fluid absorbent on a top side, and fluid impermeable on an opposite, bottom side; a angled support wedge positioned in a head support region on the top side of the sheet; and a soft foam ring member on a top of the angled support which in concert with its underlying support wedge maintains a patient's head in a sniff position. Also provided is a barrier cover having a patient head support member adjacent one end, said head support member being canted at an about 15° angle to the cover, and an operating table carriage that interfaces with the patient either directly, or through a cushion that allows the patient's head to translate along an Y axis of the rail.

A fuel vaporizer including fuel injectors is described herein. The vaporizer includes a housing having a plurality of baffles defining a plurality of chambers, with each of the plurality of baffles defining an aperture between adjacent chamber, and the apertures define a flow path from the air inlet, through the plurality of chambers, and to the vapor outlet. A conduit extends through the baffles and chambers, and the conduit is adapted to accept a flow exhaust gas and transfer thermal energy from the exhaust gas to an airflow along the flow path A fuel injector is positioned in the housing to inject fuel into the flow path in the first chamber, the thermal energy from the conduit vaporizing the fuel injected into the airflow and producing the flow of vaporized fuel. The fuel vaporizer may include a heat exchanger pre-heating the airflow and electric heating elements supplementing the conduit heating.

A table column (1) for an operating table, having: a column head support (6); a column head (7) which is received in the column head support (6) and is height-adjustable in relation to it; a lifting drive (21) for adjusting the height of the column head (7) in relation to the column head support (6); and a cylindrical guide (23) that connects the column head (7) to the column head support (6) and is used to guide the column head (7) vertically when it is adjusted in height,
wherein the cylindrical guide (23) has a longitudinal groove (24) and two keys (26) engaging therein in order to secure the cylindrical guide (23) against rotation around its vertical axis, and wherein each key (26) comprises a main body and an engagement element which protrudes along an engagement direction and which engages in the engagement direction in the longitudinal groove (24), wherein the engagement elements of the two keys (26) are arranged offset to one another transverse to the longitudinal axis of the longitudinal groove (24), so that a pre-tension is generated in the cylindrical guide (23) transversely to the longitudinal axis of the longitudinal groove (24).

A spinal deformity correction and fusion surgery supporting device is capable of simplifying the operative procedures of a spinal deformity correction and fusion surgery by an operator to reduce the operative time and lessen the burden on the patient and achieving a more effective correction rate by the spinal deformity correction and fusion surgery. In this supporting device, the waist and the vicinity thereof are pressed from both sides in the left-right direction by a pair of waist pressing bodies, and the chest and the vicinity thereof are pressed from both sides in the left-right direction by a pair of chest pressing body to establish a trunk balance. In this state, the pair of chest pressing bodies and the pair of waist pressing bodies are moved away from each other to apply a tensile load to spinal deformity and a state in which the spinal deformity is corrected so as to approach a correction rate by the spinal deformity correction and fusion surgery can be maintained. As a result, a more effective correction rate is achieved by spinal deformity correction and fusion surgery while simplifying the operative procedures of spinal deformity correction and fusion surgery, shortening the operative time, and lessening the burden on the patient.
