The ancient Egyptians are reported to have fashioned catheters from papyrus, and the ancient Greeks from reeds. A flexible urinary catheter was invented by Benjamin Franklin for the use of his brother.

He's got catheters. (Tubes inserted when he needs to.)

The history of the sphygmomanometer, or blood pressure cuff, raises useful questions about the acceptance of new medical technologies.When the blood pressure cuff first appeared in U.S. medical practice in the first decade of the 1900s, it generated some concern and debate among physicians. Review of the medical literature, a systematic study of patient records from Massachusetts General Hospital, and consideration of events in Boston during this period suggest that physicians faced several important choices associated with the early acceptance of the cuff. \n\nThe introduction of the blood pressure cuff presented physicians with several different, competing methods for assessing the force of a patient's blood flow.Physicians chose to use the cuff in a manner that preserved their exclusive use of the new tool and maintained a high level of skill for their individual practices. An early proposal to introduce the new blood pressure cuff as a simple tool for nursing use met with resistance. Many physicians initially favored a competing practice of assessing the force of blood flow by pulse palpation. Physicians eventually dropped the practice of subjectively palpating the force of blood flow and came to rely increasingly on the measurement of blood pressure using auscultation. Even after adopting the cuff into practice, however, they had little interest in completely standardizing the use of the blood pressure cuff across the practices of individual physicians.

It was not until the middle ages that the scissors started to look the way we know them today. Leonardo DaVinci, famed painter of the Mona Lisa and outstanding inventor, is most frequently credited with inventing the modern sicssor formed from two separate pieces of metal, attached at a central pivot point. \n\nHowever tools with a similar look and function, yet clearly a different tool, have been dated to 1500BC, long before DaVinci's birth in 1452. These first scissors were quite different than the ones we have today, and were formed from one piece of metal, bent and sharpened on both ends in order to form the scissor blades. This basic scissors concept is still found today in the sheep shearing industry as the classic sheering instrument. \n\nClassic scissors are made of standard carbon steel. The higher the carbon content, the harder the scissors and the harder the scissors are, the longer they will perform their cutting function. Modern manufacturing techniques also include stainless steel. This alloy is rustproof, nickel-free, and can be well hardened. Acme has recently included titanium in its manufacturing process providing increased cutting performance and longevity.

There are several people and places where hockey is claimed to have originated. Some say Kingston, Ontario (ask Don Cherry), others in a place (I forget the name) in Nova Scotia. It was most likely College students looking to make use of the elements. Personally, I don't care where or how it was invented, I just care that it was!

This started with the Egyptians who thought a vein in the left hand ring finger traveled straight to the heart.

PIC stands for percutaneous intravenous catheter. Sometimes it is necessary to receive medicine or other fluids intravenously (in the vein). If it is needed for a long period of time, the doctor might consider a PIC line as the best option. PIC lines are long, flexible tubes inserted into a large vein, usually near the elbow. The tube (medically speaking, all tubes are called catheters) is threaded up the vein until its tip reaches the large veins inside the chest.A PIC line can remain in place for several weeks or more. They are especially helpful for patients who need to receive medication at home for a long time. It is not uncomfortable. Most people have no trouble with them, and they can remain quite active while having one in place. PIC lines have bandages which are placed over the insertion site to make sure it doesn't get accidentally tugged. This bandage has to be changed every day or two. A PIC line can be used for several kinds of injections, therefore, the patient does not have to be poked so many times.

It comes from Hermes' caduceus, which has long been a sign of medical symbology representing thus medicine... Its a staff with two snakes, sometimes one encircling it to the top... it may even look like a double helix...

WHERE?\nThe question of exactly where the transfer took place, and where the 'epidemic' officially first developed has always been controversial. Some have suggested that it is dangerous to even try to find out, as AIDS has frequently been blamed on an innocent person or group of individuals in the past. However, scientists remain keen to find the true origin of HIV, as most agree it is important to understand the virus and its epidemiology in order to fight it.\n\nSo did it definitely come from Africa?\nGiven the evidence we have already looked at, it is likely that Africa was indeed the continent where the transfer of HIV to humans first occurred (monkeys from Asia and South America have never been found to have SIVs that could cause HIV in humans). However, who exactly spread the virus from Africa , to America and beyond remains a mystery. It is quite possible that separate 'pockets' of the virus could have been developing in a number of different countries years before the first cases were ever officially identified, making it virtually impossible to trace one single source.

I believe it was the 15th or 16th century France.  And that was only for the upperclass.  In fact restrooms in any traditional sense were rare until the early 19th century anywhere.  The were referred to as bath houses or water closets before that point.  They were universal as well, jsut more seperated from the general public.\n\nAncient Rome just had holes in a rock bench along a long wall.  Men and women alike sat (or stood) side by side to do their business.  \n\nIt is thought that seperate restrooms were used to encourage chastity.  Women were innocent and should not be exposed to where men relieved themselves.  They were entirely to dainty to handle that.  Plus clothing was a factor.  Women had a lot more on.  These were days before tampons as well, so that created whole new problems at certain, ahem, times.

GURNEY is a kind of cot typed stretcher for carrying patients. \n\nA gurney, known as a trolley in British medical context, is the US term for a type of stretcher used in modern hospitals and ambulances in developed areas. A hospital gurney is a kind of narrow bed on a wheeled frame which may be adjustable in height. For ambulances, a collapsible gurney is a type of stretcher on a variable-height wheeled frame, the key value of which is to facilitate moving the patient onto a fixed bed or table on arrival at the emergency room. Both types may have straps to secure the patient.\n\nThe name gurney comes from its similarity to a horse-drawn cab patented in the USA in 1883 by J. Theodore Gurney. Advanced models of collapsible gurneys have a lower frame that can fold up on contact with the rear deck of the ambulance, and have a securing device that mates with a counterpart inside the ambulance to keep it from moving during transport. Shelves, hooks, and poles for medical equipment and intravenous medication are also frequently included-.

Excellent question... you actually made me look for the answer in Wikipedia. \n\n"In 1891, Karl Elsener, then owner of a company that made surgical equipment discovered (to his dismay) that the pocket knives supplied to the Swiss Army were in fact made in Germany. Outraged, he founded the Association of Swiss Master Cutlers. Its goal was simple: Swiss knives for the Swiss Army.\n\nElsener began working on what was the predecessor to the modern Swiss Army knife, called the "Soldier's Knife". The original had a wooden handle (as opposed to the plastic and metal seen today), and featured a blade, a screwdriver, a can opener, and a punch. This knife was sold to the Swiss army, but Elsener was not satisfied with its first incarnation. In 1896, after 5 years of hard work, Elsener managed to put blades on both sides of the handle using a special spring mechanism, allowing him to use the same spring to hold them in place, an innovation at the time. This allowed Elsener to put twice as many features on the knife; he added a second blade and a corkscrew."\n\nInteresting. It appear that Elsener, through his company Victorinox, was indeed the inventor of the Swiss Army Knife.
