US Patent:

8096986, Jan 17, 2012

Filed:

Aug 24, 2009

Appl. No.:

12/583572

Inventors:

John Anderson Armistead - Easley SC, US

International Classification:

A61M 27/00

US Classification:

604544, 604256, 604264

Abstract:

While waiting for prostate-size-reducing drugs or herbs to have an effect, it's often necessary to have a catheter, like the Foley, inserted into the bladder. Urine passing through such collects in a plastic bag which must be drained, regularly, and is awkward to carry and difficult to disguise under clothing. In lieu of a Foley, full-length self-cathetering is less awkward, but the recurring process can irritate the urethra and prostate, and increase the chance of getting cystitis. The present new catheter type has a barb-like tip to retain such inside the bladder. A urine drainage inlet is located less than an inch below the barb. The easy drainage of urine is facilitated simply by pushing the catheter upward until the inlet opening is inside the bladder. Because the required insertion distance is much reduced, there's less likelihood of there being irritation of the organs, and less likelihood of getting cystitis.

Abstract:

Instant Reading Oil Dipstick Improvements is a near universal design with most assembly done by the manufacturer. The customers can easily adapt such to match their existing dipstick geometry by pushing the adjustable parts to the correct location, where they will remain. The air valve is within a single, machined brass cone that adapts to the metal tube and seals in the engine vacuum. A new tubular plastic air seal around the wire handle increases reliability. And a cone shaped rubber squeegee will automatically remove oil from the outside of the tubing as the dipstick is withdrawn from the crankcase.

Inventors:

John Anderson Armistead - Easley SC, US

International Classification:

G01F 23/04

US Classification:

33722

Abstract:

The present instant reading oil dipstick automatically extracts a representative column of oil from the crankcase oil reservoir. Such is done inside of a translucent fluoroplastic tube. A machined brass slide valve, with sealing O-rings, fits inside of the metal dipstick tubing leading into the engine crankcase. When the dipstick is withdrawn for checking oil level, the slide valve automatically closes over an air vent in the plastic tubing, thus preventing the oil that is inside the bottom of the tubing from running out. The oil level can be ascertained, easily—even in low light levels—without having to wipe off the oil from the outside of the dipstick, and without having to reinsert the dipstick one or more times.

Abstract:

Standard bow knots—which are favored on lace-up shoes—are prone to come untied. The latter is both an inconvenience and a safety issue. But no bow knot can come untied until one end of the bow has passed back through the loosened knot. The present bow retainer clips are unitary, bent wire, spring clips which fit through the upper grommets of lace-up shoes. Such clips have recesses which are aligned with a row of grommets on either the left or right side of a shoe. While the bow knot is being tied, one or both halves of the bow on either side of the knot are inserted under the clip. The wire of the latter will indent and grip the shoelace so as to make it difficult or impossible for such to be pulled back through the knot. But by deliberately removing the bow portions from under the bow retaining clips, the bows can be untied in a conventional manner. These functional bow retainer clips are small and decorative, and can be used as attachment points for jewelry charms, if desired.

US Classification:

Abstract:

Temporary relief from urine retention often accompanying prostate gland enlargement can be had by catheterization. Conventional catheters extend through the sensitive tip of the penis, causing pain, and preventing sexual relations. This invention places a valve inside the urethra that has an attached, proximal catheter which passes through the prostate into the bladder. Such valve can be opened at will by applying finger pressure against the distal valve tip and pushing upward toward the prostate. The latter tip can be felt inside the urethra, near the juncture between the penis and the scrotum. With the valve in the open position, the bladder can be nearly fully voided, regardless of the degree of enlargement of the prostate. This efficient and easy drainage of the bladder can eliminate the need to endure the painful surgical enlargement of the prostate duct—which can cause an inability to father children, normally, and may cause incontinence.

International Classification:

A61M 27/00

US Classification:

604544

Abstract:

Problems associated with prostate enlargement can be negated by using the present valved catheter. Such can be inserted and removed by the user. The catheter is retained in place by a flexible, foldable tee bar attached to the valve plug, which in turn is attached to a stretchy Nylon line. To actuate the valve, the plug can be pulled out of the upper catheter simply by pulling on the distal end of the catheter, allowing urine to drain. When the user has an erection, the penis engulfs the entire valved catheter. That helps to assure that reproductive functions will not be affected.
