System and method for predicting patient falls

A patient fall prediction system receives video image frames from a surveillance camera positioned in a patient's room and analyses the video image frames for movement that may be a precursor to a patient fall. In set up phase, the viewpoint of the camera is directed at a risk area associated with patient falls, beds, chairs, wheelchairs, etc. A risk area is defined graphically in the viewport. The patient fall prediction system generates a plurality of concurrent motion detection zones that are situated proximate to the graphic markings of the risk areas. These motion detection zones are monitored for changes between video image frames that indicate a movement. The pattern of detections is recorded and compared to a fall movement detection signature. One fall movement detection signature is a sequential detection order from the motion detection zone closest to the risk area in the frames associated with patient falls, to the motion detection zone farthest away from the risk area. The patient fall prediction system continually monitors the motion detection zones for changes between image frames and compiles detections lists that are compared to known movement detection signatures, such as a fall movement detection signature. Once a match is identified, the patient fall prediction system issues a fall warning to a healthcare provider.

Patient position monitoring device

The disclosed invention is a patient monitoring system that employs a pressure sensitive pad. The pad is placed beneath a patient who is lying in bed or sitting in a chair. When weight is removed from the pad, an alarm is given. The pad comprises an upper layer of circuitry and a lower layer of circuitry. When the respective layers of circuitry are in contact, the alarm remains off, but when the layers of circuitry become separated, the alarm is given. This invention is generally for use in hospitals and nursing homes to alert caregivers when a patient falls out of a bed or a wheelchair; or if a patient otherwise leaves a bed or chair against the wishes of the caregiver. This situation is of special concern with elderly patients, post operational patients, and / or at night when nursing staffs are reduced.

Method for acclimating a CPAP therapy patient to prescribed pressure

A method for acclimating a CPAP therapy patient to a prescribed pressure while the patient falls asleep. During an initial startup period, the CPAP apparatus applies a therapeutic IPAP pressure to the patient's airway and a lower initial EPAP pressure to the patient's airway. The EPAP pressure is ramped up to the IPAP pressure over a sufficient time for the patient to fall asleep. In a modified embodiment, both the initial IPAP pressure and the initial EPAP pressure are less than the prescribed therapeutic pressure. The IPAP and EPAP pressures are then independently ramped up to the prescribed therapeutic pressure.

Noise Correcting Patient Fall Risk State System and Method for Predicting Patient Falls

A patient fall prediction system from noise corrected surveillance video by identifying patient fall risk states. A hierarchy of discrete patient fall risk states, from no risk, to intermediate risk to critical risk, describe a patient fall risk. The system transitions from state to state based on changes detected in corresponding areas between a current video frame and a background frame. A set of fall risk state transition rules govern the entry into new fall risk states. A video frame is subdivided into multiple predetermined areas, at least two contain images of the patient. The number of false alarms are reduced by accurately defining fall risk state transition rules and by reducing the opportunity for noise to impact the state transition results. Frames that contain new changes are excluded from fall risk state processing, i.e., the first video frame that might cause an erroneous elevated fall risk state is culled.
