An ostomy plug is described comprising first and second chambers having adjacent ends coupled to, and in fluid communication with, each other. The first chamber may be for insertion into a stoma. The second chamber may contain fluid for inflating the first chamber when the second chamber is squeezed or otherwise compressed. The plug may have a figure-of-eight configuration. The plug may be configured to permit venting of flatus while obstructing escape of other body waste from the stoma. The plug may incorporate an insertion aid for aiding insertion into a stoma. The plug may also incorporate a device for regulating the inflation pressure of the fluid to avoid undesirably high inflation pressures in the stoma.

An apparatus for enhancing blood flow through a limb of a subject includes a compression sleeve extendable around the subject's limb and having a plurality of compressors situated next to one another along the sleeve. In use, the compressors compress the limb in sequence to move blood within the limb from one end of the sleeve to the other. In particular, as a said compressor begins to compress the limb, the compressor preceding it in sequence already compresses the limb, and the next preceding compressor in sequence ceases to compress the limb.

The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port. A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

A clothes structure with temperature falling device is provided, which has a fan provided in a low-permeability layer outside a clothes major body, and an air delivery space provided between the low-permeability layer and a lining layer inside. When the fan sucks the air from the outside of the clothes major body through air intake end and delivers the air to the inside of the clothes major body, air will flow uniformly in the air delivery space and to everywhere in the clothes major body. Then proper quantity of uniform air flow is output from an inner lining layer with meshes to everywhere of user's body to make user feeling cool and comfortable.

A device for adapting actual tire pressure of a tire of a wheel of a vehicle axle to a current setpoint tire pressure during travel includes a chassis-side central device and a wheel-related pneumatic pressure-control device. The pressure control device includes a second connection which is at the actual tire pressure. A control valve with an open position connects a first connection to the second connection, and with a blocking position blocks this connection. A pilot control valve performs pilot control of the control valve. The pressure control device also has a bypass line, which bypasses the control valve and the pilot control valve, connects the first connection to the second connection, and has a non-return valve which opens in the inflation direction of the tire and blocks in the deflation direction of the tire.

An occupant protection apparatus includes an airbag provided at a seat portion of a vehicle seat. The airbag is inflatable in such manner as to push up at least a part of a cushion body of the seat portion. At the time of collision of the vehicle, an ECU permits inflation of the airbag if a sensor senses that an occupant is seated on the seat, and inhibits inflation of the airbag if the sensor senses that no occupant is seated on the seat. Therefore, when no occupant is seated on the seat, inflation of the airbag is inhibited at a vehicle collision.

The present invention provides an effective oxygen generating materials, carbon dioxide absorbing materials, and transport system and transport method of live fishery products for use upon transporting live fishery products. An oxygen generating materials of the present invention is prepared by packaging solid peroxide and peroxide decomposition catalyst with a moisture-permeable material having a cup method moisture permeability (40° C., 90% RH) of more than 20 g/m2/24 hr and being impervious to water at normal pressure. Furthermore, a carbon dioxide absorbing materials are prepared by packaging alkaline earth metal hydroxide and/or oxide with a gas-permeable material having a Gurley method gas permeability (JIS P8117) of 0.1~3000 sec./100 ml of gas and being impervious to water at normal pressure. Moreover, the transport system of live fishery products are a transport system wherein the oxygen generating materials and carbon dioxide absorbing materials pertaining to the present invention are sealed inside a transport bag.

An angioplasty catheter and method for making and using the same. An angioplasty catheter comprises an inner tube having a proximal end, a distal end, and a lumen extending therethrough; an outer tube disposed over the inner tube, the outer tube having a proximal end and a distal end; a balloon coupled to the distal end of the outer tube; an inflation lumen defined between the inner tube and the outer tube, the inflation balloon in fluid communication with the balloon; and a support block coupled to the inner tube. In addition, a method for manufacturing an angioplasty catheter is disclosed.

A nest-like mattress is disclosed. The mattress comprises a multiple compartments and a nest-like fitting characterized in that the multiple inner compartments are soft, air-filled sac structure and are fitted within an individual cavity of the nest-like fitting, each air-filled inner compartment is provided with an independent nozzle, and the inner compartment has a pulling strap which allows mounting at corresponding cavity of the nest-like fitting, the nest-like fitting is provided with a plurality of cavities and each cavity allows an inner compartment and the air-filled inner compartments are located on the individual cavity, the lateral side opening of the fitting is provided with a covering cloth, the edge of the covering cloth and that of the fitting are mounted with zip or fastening/button member so as to close the side opening.

A catheter has an inflatable assembly at its distal portion, including a containment chamber, an axial core and a plurality of longitudinally oriented partitions extending from the axial core to the wall of the chamber to divide the containment chamber into at least four inflatable sectors. Hydraulic valves are connected to respective sectors to enable selective inflation of the sectors by a fluid when the valves are connected to a source of the fluid, and at least one surface electrode is mounted on each of the sectors. When introduced into a heart chamber and diametrically opposed sectors are inflated the assembly is stably fixed against the walls of the heart chamber and readings can be obtained from the surface electrodes of the inflated sectors.
