A patient positioning apparatus (200) for use with a mattress comprises a first lateral tilt bladder (10) and a third lateral tilt bladder (14) configured to underlie a first side of the mattress, and a second lateral tilt bladder (12) and a fourth lateral tilt bladder (16) configured to underlie a second side of the mattress. The tilt bladders are inflatable to alter the position of a patient lying on the mattress, and inflation and/or deflation of the lateral tilt bladders is controllable by a controller (120). The first lateral tilt bladder is configured to tilt the patient's sternum towards the second side of the mattress when inflated, the second lateral tilt bladder is configured to tilt the patients sternum towards the first side of the mattress when inflated, the third lateral tilt bladder is configured to tilt the patients pelvis towards the second side of the mattress when inflated, and the fourth lateral tilt bladder is configured to tilt the patients pelvis towards the first side of the mattress when inflated. A first check valve (28) is configured to allow fluid communication in one direction from the third lateral tilt bladder to the first lateral tilt bladder, and a second check valve (30) is configured to allow fluid communication in one direction from the fourth lateral tilt bladder to the second lateral tilt bladder. In a preferred aspect, the first and second lateral tilt bladders extend in a longitudinal direction from a waist portion towards a head end of the patient positioning apparatus and have a length of between 690 mm and 950 mm. A mattress and mattress system are also provided.

A patient support system with chest compression system and harness assembly with sensor system. The harness assembly secures shoulders and hips of the patient on a patient support surface during transport. A chest compression system is integrated into the harness assembly in a manner that provides chest compressions to the patient while the patient is secured on the patient support surface. The tension of the harness assembly is selectively adjusted and/or a fluid bladder may be selectively expanded. A controller is in communication with the chest compression system and controls operation of the chest compression system. The sensor system is integrated into the harness assembly and in communication with the controller. The chest compression system may be removable from the harness assembly via an adapter. The chest compression system may be integrated into the patient support apparatus to secure the patient to the patient support surface while providing chest compressions.

Introduced here are methods, apparatuses, and systems for mitigating the contact pressure applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, a controller can vary the contact pressure on the human body by controllably inflating one or more chambers, deflating one or more chambers, or any combination thereof. By monitoring the pressure in each chamber over time, the controller can also gain an enhanced understanding of movement(s) performed by the human body when positioned on the pressure-mitigation apparatus.

A patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus. A barrier assembly is secured to the upper frame by a tab which is received into a receiver formed in a head end of the frame.

A patient support system is provided for use on a litter of a patient support apparatus. The patient support system includes an expandable patient support and a control assembly connectable to the expandable patient support. The control assembly includes an inflator and a controller configured to provide pressure in one or more inner bladders at a first value when the expandable patient support is at a first width and reduce the pressure in the one or more inner bladders to a second value, lower than the first value, in response to inflating one or more outer bladders to expand the expandable patient support to a second width.

The pressure sensing mat including a first portion and a second portion. The first portion may include a first conductive layer that may be sandwiched between a first non-conductive layer and a non-conductive layer that define a first set of channels that may at least partially enclose a first conductive strip that may extend in a first direction. The second portion may include a second conductive layer that may be sandwiched between a third non-conductive layer and a fourth non-conductive layer that may define a second set of channels that may at least partially enclose a second conductive strip that may extend in a second direction. The first conductive strip and the second conductive strip may form a capacitor that may be configured to provide a capacitance indicative of a pressure applied to the capacitor.

A lift system includes a hoist module, a support assembly which is movable relative to the hoist module, and a control system. The control system is adapted to enable a user to a) issue an operational command which causes the support assembly to move to an operational destination, and b) issue a stowage command which causes the support assembly to move to a stowage destination. The control system is also adapted to A) disregard the stowage command provided at least one condition is satisfied and/or B) encumber issuance of the stowage command Equivalently, the control system adaptation is to A1) disregard the stowage command provided at least one stowage contraindication condition is satisfied or A2) not disregard the stowage command provided at least one stowage noncontraindication condition is satisfied and/or B) encumber issuance of the stowage command.

A hospital bed may include a support structure, a controller, a pressure source coupled to the controller, and a hospital bed mattress carried by the support structure and having first and second ends, and first and second sides extending between the first and second ends. The hospital bed mattress may include bladders coupled to the pressure source. The bladders extend between the first and second ends and between the first and second sides and configured to provide pressure differential. The controller may be configured to pseudo-randomly adjust an internal pressure of each of the bladders.

A patient turning device for a patient support apparatus. The patient turning device includes a first and second bladder assembly each including a plurality of layers and seals defining a bladder volume. The bladder volumes are selectively inflatable with fluid to expand the respective bladder assembly, and consequently move a patient support surface of the patient support apparatus. A portion of a lower layer of the first bladder assembly and a portion of an upper layer of the second bladder assembly define an overlapping region of the bladder volumes. The patient turning device is coupled to an underside of a carrier sheet and positioned between a crib assembly and a bottom cover. An augmenting feature is configured to resiliently expand as at least one of the first and second bladder assemblies receives the fluid to move at least a portion of the crib assembly away from a patient support deck.

The present invention relates to an ambulance having an infectious disease blocking function and an interior pressure control method therefor, the ambulance having a driver seat, a vehicle body and an emergency care compartment which is mounted on the vehicle body and which has a space in which a patient can be placed, and comprising an air pressure regulation part for setting the inside of the emergency care compartment to have a positive pressure or a negative pressure, and a control part for selectively controlling a positive pressure or a negative pressure of the air pressure regulation part.
