An improved nasal cannula for isolating, monitoring and measuring the content of a patients exhaled gases. The cannula includes an integral connector that is attached to the wall of a hollow nare to create a gas-tight interface. The other end of the connector is attached to tubing that forms an integral seal with the cannula port to create a continuous, gas-tight flow channel that is separated from the hollow cannula body. The integral connector provides a direct, isolated flow channel that eliminates the undesirable dead space in which exhaled gases from a patient can be entrapped and stagnate, resulting in cross contamination.

A method and apparatus are disclosed for determining a negative pressure generated by a suction pump of a topical negative pressure (TNP) system. The method includes the steps of disconnecting a drive voltage from a pump of the TNP system, determining an EMF generated by a free-wheeling element of the pump, selecting a new drive voltage for the pump and reconnecting the new drive voltage to the pump.

A method and apparatus for stimulating a muscle of a subject are provided. The apparatus comprises a signal generator for generating an electrical pulse signal of a frequency and a current amplitude for inducing contractions in the muscle, and an electrode apparatus for applying the signal to nerves associated with the muscle to be stimulated or adjacent the muscle of the subject for stimulating the muscle. The frequency and current amplitude of the electrical pulse signal are selected so as to maximize the bulk of the muscle being subjected to the contractions so as to generate a shivering phenomenon therein.

A composition for promoting the formation of clots in blood comprises a binder and a zeolite disposed in the binder, the zeolite having an adjusted calcium content. A method of forming a blood-clotting composition comprises the steps of providing a zeolite, combining the zeolite with a binder, and adjusting a calcium content of the zeolite to have an amount of calcium such that upon application of the composition to a wound, a heat of hydration is reduced and thereby heat transferred to the wound is reduced. A method of clotting blood flowing from a wound comprises the steps of applying a zeolite to the wound and maintaining the zeolite in contact with the wound for a predetermined amount of time. The zeolite preferably has an adjusted calcium content and is capable of producing a controllable blood clotting effect on the wound.

A flexible membrane is situated within a rigid or semi-rigid cap. The edge of the cap wall is adhesively fixed to the tissue surrounding the stoma. The interior of the cap is pressurized to press the membrane to seal the stoma against the discharge of solid and semi-solid waste. Gas escapes through a vent with a filter element. The cap can be pressurized by an external pump or an integral pump member situated on top of the cap. A relief valve prevents over pressurization. A collection pouch can be provided as part of a device. The device can be removably mounted on a standard two-piece faceplate.

The present invention discloses a stereoscopic display employing polarized eyewear. The basic component of the present invention stereoscopic display is a stereopolarizer, which is a polarized screen comprising microscopic sections of mutually extinguishing polarizing filters dispersed throughout the screen. To achieve the proper resolution, the size of the microscopic polarizing filter needs to be in order of micrometer, from a few microns to a few hundred of microns. The arrangement of the microscopic polarizing filters can be alternating stripes in horizontal, vertical, or any arbitrarily direction. The microscopic polarizing filters can be arranged in alternating pattern, such as alternating square or circle. The polarizer screen can be one sheet or can be a composite sheet, comprising two distinct polarizer filter sheet laminated together. Laser drilling is used to fabricate the microscopic polarizing filters, primarily due to ease of operation and appropriate microscopic sizes. Further, laser drilling and cutting can form angle holes in the stereopolarizer, which provides optimum focus viewing for horizontal perspective display.

An improved exercise device in the nature of a kettlebell. The device has a frame covered by a shroud that is configured to lessen the impact of the device on the user. There are a plurality of weights that can be easily attached and detached from the frame to increase or lessen the load to the user. The weights are designed so that they can be added or taken away without altering the center of gravity of the device or the external physical shape of the device. There is also a base that holds the device while the weights are being changed and which also interacts with the device to assist in that exchange. The attaching and detaching system includes a pin that is used to affix the weights to the frame. A dual locking system assures that the pin does not inadvertently come loose during use of the device.
