Patent number: 5324003Abstract: A camper jack for mounting on a camper body, the jack having an extensible leg projectable from a hollow jack housing and attached to the camper body along the length of the housing. A piston cooperating in a cylinder in the extensible leg extends the leg from the housing. A hydraulic fluid reservoir is formed in the extensible leg in an annular space surrounding the cylinder. A valve block is coextensive with the extensible leg at the foot of the leg and contains the valves and pumping piston for the jack. Valving in the valve block permits manual extension and retraction of the extensible leg. Grooves are provided in a novel needle valve allowing control of the rate of flow of the hydraulic fluid. Pumping motion is controlled by a pump handle receiver.Type: GrantFiled: November 30, 1992Date of Patent: June 28, 1994Inventor: C. Martin Rasmussen

Patent number: 5322253Abstract: A universal mounting system for attaching any of a variety of I.V. devices to an I.V. pole. The mounting system has both a C-clamp and a spring-actuated clamp. The C-clamp attaches to the I.V. pole with a threaded stud that is manually adjustable with a knob. The spring-actuated clamp secures the I.V. device and is pivotally connected to the C-clamp by a pivot-screw that extends through both a spring and a non-threaded bore that is formed in the C-clamp, and exits at a recess area on the C-clamp. The pivot-screw is threaded into a threaded bore that extends through a projection on the spring-actuated clamp. The projection fits within the recess to prevent pivoting of the spring-actuated clamp relative to the C-clamp. The spring-actuated clamp has two aligned, opposing and spring-loaded clips for holding I.V. devices. The clips pivot and fulcrum together at a pivot point between the ends of each clip so as to bring the clip ends together to a clamped position on an I.V. device.Type: GrantFiled: December 2, 1992Date of Patent: June 21, 1994Assignee: Merit Medical Systems, Inc.Inventor: Brian Stevens

Patent number: 5309604Abstract: A clip device for holding flexible tubing in a coiled arrangement, where one end of the tubing is connected to an external device, such as an infusion pump. The clip has a bore formed through it at one end so that the clip may be slidably and permanently mounted on the flexible tubing. The clip also includes two C-shaped channels, one located at the bottom of the clip and the other along a side of the clip, that are sized to receive and frictionally engage the loops formed in the flexible tubing. The tubing is then coiled and firmly held in the coiled state by looping and engaging each loop in one of the C-shaped channels. The clip is capable of firmly holding the tubing in a coiled state, but the C-shaped channels are shaped and oriented on the clip such that when a user needs to use the flexible tubing, the user may pull on the free end of the flexible tubing whereby the loops are released from the C-shaped channels resulting in the uncoiling of the tubing.Type: GrantFiled: March 11, 1993Date of Patent: May 10, 1994Assignee: Merit Medical Systems, Inc.Inventor: C. Eric Poulsen

Patent number: 5292099Abstract: The invention comprises a display mounted document holder devised to clamp to a display monitor, having a document platen on either the right side or the left side, or both sides, wherein the document platen can be positioned vertically in a plurality of positions, and wherein the document platen is normally tilted and oriented so as to substantially face the user, but is capable of being tilted in a variety of angles. The document platen may be swung from a position substantially facing a user to a position substantially facing the side of the display monitor to free valuable working space. The document platen is swung by means of a hinge located on the arm which secures the position of the document holder relative to the display monitor. The hinging action is monitored by a locking mechanism which may be operated from either the left or right sides of the display monitor. The document platen also incorporates a copy marker and a copy clamp.Type: GrantFiled: February 26, 1992Date of Patent: March 8, 1994Assignee: William R. IshamInventors: William R. Isham, Dale A.

Patent number: 5291951Abstract: Fire fighting apparatus for generating air compressed foam having both a water and a surfactant metering device for dispensing controlled and discrete quantities of both into a mixing conduit where they combine into a foam solution. The foam solution is combined with air prior to being injected within a compression chamber of an air compressor device. Foam is generated by compression of the air-foam solution and then is discharged through a discharge device. The air compression device is also controlled to dispense a discrete quantity of foam therefrom in correlation with the discrete quantities dispensed from the other two metering devices. The quantitative dispensing coordination of the air compression device with the two metering devices makes all three devices both relational and proportional in the cooperative generation of compressed air foam, and thus ensures prompt production of constant quality foam.Type: GrantFiled: December 28, 1992Date of Patent: March 8, 1994Assignee: Utah La Grange, Inc.Inventor: James W. Morand

Patent number: 5291887Abstract: The present invention is directed to novel methods and apparatus for noninvasively collecting substances through mucosal tissues. The concentration of a substance in blood is monitored noninvasively by correlation with the amount of the substance which permeates a mucosal membrane into a substance receiving medium over a specified time period. The substance receiving medium may include an substance permeation enhancer capable of increasing the substance permeability across the mucosal membrane. The substance receiving medium is positioned against the mucosal membrane. After sufficient time delay, the substance receiving medium is removed and analyzed for the concentration of a substance to be measured using known analytical techniques.The apparatus within the scope of the present invention includes means for supporting the substance receiving medium. The means for supporting the receiving medium provides an added benefit of isolating the substance receiving medium from contamination sources.Type: GrantFiled: June 2, 1992Date of Patent: March 8, 1994Assignee: Anesta CorporationInventors: Theodore H. Stanley, Jie Zhang
