Hypodermic
A hypodermic needle (from Greek ὑπο- (''hypo-'' = under), and δέρμα (''derma'' = skin)), one of a category of medical tools which enter the skin, called sharps, is a very thin, hollow tube with one sharp tip. It is commonly used with a syringe, a hand-operated device with a plunger, to inject substances into the body (e.g., saline solution, solutions containing various drugs or liquid medicines) or extract fluids from the body (e.g., blood). Large-bore hypodermic intervention is especially useful in catastrophic blood loss or treating shock. A hypodermic needle is used for rapid delivery of liquids, or when the injected substance cannot be ingested, either because it would not be absorbed (as with insulin), or because it would harm the liver. It is also useful to deliver certain medications that cannot be delivered orally due to vomiting. There are many possible routes for an injection, with intramuscular (into a muscle) and intravenous (into a vein) being the ...

Syringe And Hypodermic
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle or tubing to direct the flow into and out of the barrel. Syringes are frequently used in clinical medicine to administer injections, infuse intravenous therapy into the bloodstream, apply compounds such as glue or lubricant, and draw/measure liquids. There are also prefilled syringes (disposable syringes marketed with liquid inside). The word "syringe" is derived from the Greek σύριγξ (''syrinx'', meaning "Pan flute", "tube").

Charles Hunter (physician)
Charles Hunter (18358 August 1878) was an English physician best known for coining the word " hypodermic" and for realising that injections of morphine could relieve pain anywhere in the body, regardless of where the injection was delivered. Life Charles Hunter was the only son of surgeon Dr John Charles Hunter of Belgrave Square, London. Hunter qualified as a Member of the Royal College of Surgeons in 1856. He then became House Surgeon at St George's Hospital in London and also worked at the Royal Pimlico Dispensary. Hypodermic research and debate over injection methods Hunter was very early in his career when he became interested in using syringes to administer injections of pain relief. In the 1860s, he improved on the design of the syringe that had been invented by Alexander Wood by adding the needle point and lateral opening. He also created a locking mechanism to prevent the needle from becoming detached when the plunger was pushed. Hunter initially followed Wood's method ...

Intravenous
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Rynd
Francis Rynd AM, MRCS, MRIA (1801–1861) was an Irish physician, known for inventing the hollow needle used in hypodermic syringes. Background Rynd was born in Dublin, Ireland, in 1801 to James Rynd and his third wife Hester Fleetwood, of Ryndville Castle, County Meath and Derryvolan, County Fermanagh, Ireland, respectively. Rynd attended medical school at Trinity College, Dublin, where he was reputed to be a "wayward" student, known for his busy social life and love of fox hunting. Career Rynd worked at the Meath Hospital in Dublin. At the Meath Hospital he trained under surgeon Sir Philip Crampton. Rynd became a member of the Royal College of Surgeons in 1830.

Single-use Medical Devices
Single-use medical devices include any medical equipment, instrument or apparatus having the ability to only be used once in a hospital or clinic and then disposed. The Food and Drug Administration defines this as any device entitled by its manufacturer that it is intended use is for one single patient and one procedure only. It is not reusable, therefore has a short lifespan, and is limited to one patient. There are countless types of single use medical devices, ranging from external, such as plastic gumboots, gloves and bandages merely used to assist a patient to more complex and internal devices, consisting of sharp blades, needles and tubes. Both these devices are single used, because of multiple reasons, but mainly, as it came in contact with radioactivity, blood, infection and disease or human tissue and must therefore be terminated. Each country has its own strict legislation regarding medical waste and the reprocessing of medical devices in hospitals and clinics.__TOC__ ...

Charles Pravaz
Charles Gabriel Pravaz (24 March 1791 – 24 June 1853), a French orthopedic surgeon, pioneered the hypodermic syringe. While the concept dated to Galen, the modern syringe is thought to have originated in 15th-century Italy, although it took several centuries for the device to develop. In 1657 the Englishmen Christopher Wren and Robert Boyle conducted experiments on syringe-like devices, while about 1720 the French physician Dominique Anel developed the modern pump syringe as a device to clean wounds using suction. Clinicians could not perform injections without an incision until Irish physician Francis Rynd invented the hollow needle in 1844. In 1853, wanting to inject iron perchloride coagulant Coagulant can refer to: * Flocculation * Coagulation of the blood * Coagulation (water treatment) See also * Coagulation (other) Coagulation is the process by which blood forms clots.

Agar
Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori ('' Gracilaria'') and "tengusa" ('' Gelidiaceae''). As found in nature, agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling. These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum. The processing of food-grade agar removes the agaropectin, and the commercial product is essentially pure agarose. Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative; an appetite suppressant; a vegan substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and ot ...
