摘要:
A ventilator intended to be connected to a patient for breathing therapy has a control unit having an input for receiving EMG signals from an EMG detector and an output for an EMG based control signal and a pneumatic unit for generating breathing gas flows dependent on the EMG based control signal is described. The ventilator has a detector for determining a parameter related to breathing dynamics for the patient, this detector being connected to the control unit and control unit controlling the pneumatic unit dependent on the parameter related to breathing dynamics in the case of loss of EMG signals at the input.

A delivery apparatus for pressurized medical liquids comprising a reservoir for medical liquid and a pressurizing means configured for pressurizing medical liquid to a driving pressure; with a diffusion barrier arranged to float on medical liquid in the reservoir and disposed to cover substantially the entire surface of the medical liquid in the reservoir for the purpose of preventing diffusion of gas present in the reservoir into the medical liquid.

A basketball game includes a generally planar backboard supporting a circular hoop having a basketball net extending downwardly therefrom. A center housing is supported beneath the hoop and secured to the backboard. A pair of score indicators having digital score indicating displays are supported on either side of the backboard. A pair of slap actuated depressible slap-pads are secured to and supported by the indicator housings. A flexible score sensor is secured to the center housing and extends into the net passage. The score sensor includes a flexible joint having a flex gauge or strain gauge operative therewith to provide an electrical signal each time the ball is successfully shot by a player and passes through the hoop and basketball net. In the preferred play pattern, the player having successfully scored a basket is able to increment the player's indicated score by slapping the appropriate one of the slap-pads following the successful shot. In the absence of a successful preceding shot, the slap-pads remain ineffective and operation thereof fails to alter the displayed player's score. A multi-jointed, generally tubular support frame supports the backboard and basketball hoop at a predetermined adjustable height.

A vaporizer arrangement for a breathing apparatus serves the double purpose of vaporizer and pressurized supply of vapor-containing gas for direct delivery to a patient. The vaporizer arrangement has at least a first gas inlet channel for conveying a flow of a carrier gas into a vaporization chamber, a vaporizer for vaporizing a liquid into the carrier gas in the vaporization chamber, and a gas outlet channel for conveying a flow of vapor-containing carrier gas out of the vaporization chamber and toward the patient. The vaporizer arrangement further has a gas flow regulator that maintains the carrier gas within the vaporization chamber at an overpressure, and that controls the flow of vapor-containing carrier gas out of the vaporization chamber in a variable manner.

A valve arrangement has a valve housing with an inlet and an outlet and a flow regulator including a porous body that is displaceable in the valve housing between the inlet and the outlet. The porous body blocks flow between the inlet and the outlet except for flow through the porous body. The displacement of the porous body between the inlet and the outlet proportionally varies a size of an outer surface of the porous body that is exposed to the outlet, thereby regulating fluid flow between the inlet and the outlet.

A passive optical component directs first electromagnetic radiation incident on the component in a first direction and second electromagnetic radiation incident on the component in a second direction to a mutual direction. The optical component comprises an interacting surface which is arranged to interact with said first and second electromagnetic radiation. The interacting surface comprises first portions, each having a surface extending in a third direction, which is essentially perpendicular to the mutual direction, and second portions, each having a surface extending in a fourth direction. The optical component reflects essentially all the first electromagnetic radiation and transmits at least a significant portion of the second electromagnetic radiation for directing the first and the second electromagnetic radiation to a mutual direction. An optical system and a method using the passive optical component are also shown.

In a method and breathing apparatus for assessing pulmonary stress, wherein pressure controlled flow of respiratory gas is generated, an ensuing flow is measured, resistance and compliance are determined based on measured pressure and flow and a stress index value is determined based on pressure, flow, resistance and compliance. The stress index value is 1 when no stress is present, ≧1 when there is a risk for overdistension and ≦1 when alveolar units are at a risk of being cyclically closed and opened. Implemented in a breathing apparatus the method can be used to assist an operator in diagnostic and therapeutic considerations in relation to a patient.
