45results about How to "Preventing inflation" patented technology

A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the user. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.

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.

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.

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.

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.

An airbag includes a tuck that is formed by tucking a part of the outer circumferential wall toward an interior of the airbag. The tuck includes two opposing walls, a turn-round region that forms a bottom of the tuck and outermost ends of the opposing walls adjacent to and continuing to an outer surface of the airbag. The airbag further includes a temporary joint that joins the opposing walls of the tuck together in such a manner as to disjoint when an inner pressure of the airbag at inflation is increased. The temporary joint is formed into such a line that extends toward the turn-round region and has a first end proximate the outermost ends and a second end in the vicinity of the turn-round region.

A method of preventing inadvertent inflation of an implantable prosthetic includes biasing a valve assembly such that an outlet is substantially closed and using inadvertent pressure increases from the inlet to supplement the biasing of the valve assembly. It may further include the step of preventing fluid flow through the outlet by selectively varying fluid pressure within a bypass passageway having a first end which is in fluid communication with an inlet and a second end which is in fluid communication with a chamber. And, may also additionally include the step of displacing a flexible abutting wall disposed between the chamber and the valve assembly so that the abutting wall is caused to contact the valve assembly and urge the valve assembly into a closed position when the fluid pressure within the chamber exceeds a predetermined amount.

An impact protection apparatus is provided, comprising a gas container configured to hold a compressed gas and an inflatable member configured to be inflated by the gas and function as an airbag of a movable object, such as an aerial vehicle. A valve controls flow of gas from the container to the inflatable member in response to a signal from a valve controller. The valve and valve controller are powered by an independent power source than one or more other systems of the movable object. A safety mechanism may also be provided that, unless deactivated, prevents inflation of the inflatable member.

An inflatable structure may be formed from a single piece of flexible film. The inflatable structure may include quilting seals which divide the inflatable chamber. The inflatable structure may include a one-way valve including an internal valve opening, a channel, and an external valve opening. A locator aperture positioned in the channel may be surrounded by a valve position-retention seal. A corresponding inflation device fills the inflatable structure with air and may do so without requiring heat sealing or insertion into the one-way valve. The inflation device may include a mechanical registration device configured to engage the locator aperture and position the one-way valve at a desired position with respect to an outlet of a source of pressurized air. The inflation device may detect when the inflatable structure is filled with a desired amount of air and automatically shut off the source of pressurized air.

A vehicle side air bag apparatus includes: a bag that is housed within a side portion outside in a seat back in a vehicle width direction and inflates and expands to a vehicle front side of the side portion by supplying gas; an up-down partition that partitions the bag into lower and upper bag portions; a right-left partition which partitions the lower bag portion into left and right chambers, to which a right-left communication port is provided and which inhibits inflation of the lower bag portion in an upper and lower direction by being extended in the inflation and expansion state; an inflator provided in the upper bag portion; and a flow regulating portion that distributes gas into one of the left and right chambers and the upper bag portion and limits gas flow from the one chambers to the upper bag portion by a check valve portion.

The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow.
