Syringe Syringe The hypodermic syringe, also known as the hypodermic needle, is a device used by medical professionals to transfer liquids into or out of the body. It is made up of a hollow needle, which is attached to a tube and a plunger. When the plunger handle is pulled back, fluids are drawn into the tube.

The fluid is forced out through the needle when the handle is pushed down. The syringe was introduced in the mid s and has steadily improved with the development of new materials and designs.

Today, it has become such an important medical tool that it is nearly a symbol synonymous with the practicing physician. History Since the advent of pharmaceutical drugs, methods for administering those drugs have been sought. Various important developments needed to occur before injections through a hypodermic syringe could be conceived.

Early nineteenth century physicians were not aware that drugs could be introduced into the body through the skin.

One early experiment that demonstrated this idea, however, was performed by Francois Magendie in In his published work, he outlined a method for introducing strychnine into a dog by using a coated wooden barb. Lesieur described another method for administering drugs through the skin, applying them directly to blisters on the skin.

Expanding on results from these experiments, G. Lafargue developed a procedure for introducing morphine under the skin using a lancet.

A drip needle was invented by F. Rynd in for the same purpose. However, he did not publish his method untileight years after the first hypodermic syringe was described. The first true hypodermic syringe was created by Alexander Wood in He modified a regular syringe, which at that time was used for treating birthmarks, by adding a needle.

He then used this new device for introducing morphine into the skin of patients who suffered from sleeping disorders. A few years later, he added a graduated scale on the barrel and a finer needle.

These modifications were enough to attract the attention of the rest of the medical community, resulting in its more widespread use. Over the years hypodermic syringes have undergone significant changes that have made them more efficient, more useful, and safer. One such improvement was the incorporation of a glass piston within the cylinder.

This innovation prevented leaks and reduced the chances of infections, making the device more reliable. The technology for the mass production of hypodermic syringes was developed in the late nineteenth century. As plastics developed, they were incorporated into the design, reducing cost and further improving safety.

Background The way in which a hypodermic needle works is simple.

Fluid, such as a drug or blood, is drawn up through a hollow needle into the main tube when the plunger handle is pulled back. As long as the needle tip remains in the fluid while the plunger handle is pulled, air will not enter. The user can determine exactly how much material is in the tube by reading the measuring marks on the side of the tube.

The liquid is dispensed out through the needle when the plunger handle is pushed back down. The term hypodermic syringe comes from the Greek words hypo, meaning under, and derma, meaning skin.

These terms are appropriate because they describe exactly how the device functions. The needle is used to pierce the top layer of the skin, and the material in the tube is injected in the layer below. In this subcutaneous layer, most injected materials will be readily accepted into the bloodstream and then circulated throughout the body.

A syringe is one of three primary methods for introducing a drug into the body.

The above mentioned advantages and design elements of this invention will become apparent from the following description taken in connection with the accompanying sketches, wherein is set forth by way of illustration and example, preferred embodiments of this invention. its novel pre-filled syringe concept ‘Syreen.’ A revolutionary ‘green’ syringe design Instead of glass, Syreen syringes are made with COP (cyclic olefin polymer) plastic, which has enabled Cambridge Consultants to shed the need for secondary packaging altogether, a first in this medical device arena. For the design of the mechanism to hold and secure the syringe during the process of needle insertion and syringe dosing, several concepts were generated. The following is a presentation of the feasible approaches to securing the syringe.

The others are transepidermal through the skin and oral. Using a hypodermic needle as the method of drug administration has some significant advantages over oral ingestion.

First, the drugs are protected from the digestive system. This prevents them from being chemically altered or broken down before they can be effective.

Second, since the active compounds are quickly absorbed into the bloodstream, they begin working faster. Finally, it is more difficult for the body to reject drugs that are administered by syringe.The first several pages will attempt to describe the design in everyday language, keeping numbers to a minimum and avoiding formulas and jargon.
