The invention relates to estimation of a patient's propensity to suffer from symptomatic hypotension during extracorporeal blood treatment. An electromagnetic test signal, which is applied over a thoracic region of the patient via at least one transmitter electrode. A result signal produced in response to the test signal is received via at least one receiver electrode on the patient. A test parameter is derived based on the result signal. The test parameter expresses a fluid status of the thoracic region of the patient, and it is determined whether the test parameter fulfills an alarm criterion. If the test parameter fulfills an alarm criteria, an alarm signal is generated. This signal indicates that the patient is hypotension prone, and that appropriate measures should be taken.

A seat mounted side impact airbag module for protecting an occupant of a vehicle has an airbag with a first inflation chamber for engaging the pelvic region of the vehicle occupant and a second inflation chamber for engaging the thoracic region of the vehicle occupant. The inflation chambers are separated by a chamber separator. An inflator provides inflation gas to fill the airbag housed in a tubular housing manifold having a first aperture and a second aperture. The housing manifold is shaped to retain the inflator and create two discrete flows of inflation gas. A first flow of inflation gas goes into the first inflation chamber via the first aperture and a second flow of inflation gas goes into the second inflation chamber via the second aperture. The chamber separator is tightly sealed around the housing manifold to prevent the first flow and second flow to pass into the other inflation chamber. The chamber separator may be rubber coated with the housing manifold having a recess adapted to accept and hold the chamber separator sealed in a gas tight manner around the exterior of the housing manifold.

A system for manipulating a heart during cardiac surgery links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the system for manipulating a heart during cardiac surgery of the present invention. The system is an improvement on the retractor disclosed in parent application Ser. No. 08/936,184 filed on Sep. 17, 1997 and locates a suspension head near the apical region of the heart and a gross support near the base of the heart near the AV groove. A frame is positioned within the patient's thoracic region and moves with the patient, and a surgical target immobilizer can be used to assist in the movement of the heart if desired. A special suction cup is used which accommodates multiplanar movement of the heart and the myocardium while also preventing heart tissue from interrupting the suction being applied to the heart. One form of the system can be used in minimally invasive surgery.

The brassiere prevents gravitation of the breast tissue to the lateral sides, keeps the breast tissue away from the mid center, and supports the weight of the breasts. The brassiere is designed to promote less pain, less wound complications, esthetically improved wound healing, less heat generation, improved wound inspection and access for wound care, while maintaining support and dignity.

One embodiment of an orthopedic posture brace comprising a holster strap that forms two arm loops when attached to an axial strap and two abdominal straps. When worn, the holster straps encircle the user's shoulders. The axial strap will rest against the thoracic region of the user's back. After the two abdominal straps pass through a loop at the bottom of the axial strap, the two ends not connected to the holster strap may be fastened together around the front of the user's abdomen. Tightening the ends of the abdominal strap will cause tension in the holster straps urging the user's shoulders rearward to encourage proper spinal alignment and reduced slouching or hunching over. The amount of tension generated by tightening the abdominal straps will determine how far back toward the spinal column the user's shoulders are pulled.

What is disclosed is a system and method for processing a video acquired using a 2D monocular video camera system to assess respiratory function of a subject of interest. In various embodiments hereof, respiration-related video signals are obtained from a temporal sequence of 3D surface maps that have been reconstructed based on an amount of distortion detected in a pattern placed over the subject's thoracic region (chest area) during video acquisition relative to known spatial characteristics of an undistorted reference pattern. Volume data and frequency information are obtained from the processed video signals to estimate chest volume and respiration rate. Other respiratory function estimations of the subject in the video can also be derived. The obtained estimations are communicated to a medical professional for assessment. The teachings hereof find their uses in settings where it is desirable to assess patient respiratory function in a non-contact, remote sensing environment.
