Disposable Medical Face mask

Disposable Medical Face mask

Our foray into medical consumables market began with the launch of O-Care medical face mask when Covid-19 broke out in the first quarter of 2020. It is no more breaking news that COVID-19 pandemic has changed the face of the world and people living in it. Economy, Education, Businesses, Religion, Sports, Entertainment and other human activities were disrupted since the evolution of this pandemic. The world is yet to find a reliable preventive vaccine or a curative drug to arrest this scourge. Respiratory hygiene has taken a center stage in curbing the spread of this contagious virus. Wearing a face mark is also one of the ways of preventing yourself from other carriers and ensuring that you don‘t transmit the virus to other innocent people in case you are already a victim. It was a shock for us to learn prior to Covid19 pandemic that there was no local medical face mask manufacturing facility in Nigeria. It is this gap that Transgreen Nigeria Limited is here to fill and to contribute her quota in fighting pandemics and to promote health security in the country.

There are two major classifications of Face Mask

Non-Medical Face Masks (Non-Surgical or Community Masks) include various forms of self-made or face covers; made of cloths, textiles or other materials such as rubber or paper. They may protect from pollen and dust but has zero protection against bacteria and all known viruses. Depending on the material used in the production, they may pose a health respiratory risk.

Medical Face Masks (also referred to as Surgical Masks) is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. It protects from airborne infectious diseases such as bacteria and viruses, bodily fluids and particulate matter.

A surgical or medical mask helps block:
• Large particle droplets
• Splashes/sprays
• Splatter

Medical Face masks are commonly used in surgeries and outpatient department (OPD) sessions in order to shield medical professionals from possible contaminations. With advent of Covid19 pandemic the use of medical face mask has extended beyond the hospitals. All health-conscious persons who wants to be genuinely protected from the contagious virus have adapted medical face mask as part of his or her daily clothing whether at home or outside the home.

Disposable Medical Syringes:

O-Care Syringes is the second product of Transgreen Nigeria Limited. It was designed through observance of all the industry best practices in a “class 100,000 clean room environment.” It comes in four different sizes of 0.5ml, 2ml, 5ml and 10ml.
 
The hypodermic medical syringe 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-1800s and has steadily improved with the development of new materials and designs. Today, it has become such an important medical consumable/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 1809. In his published work, he outlined a method for introducing strychnine into a dog by using a coated wooden barb. In 1825, A. J. 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. V. Lafargue developed a procedure for introducing morphine under the skin using a lancet. A drip needle was invented by F. Rynd in 1844 for the same purpose. However, he did not publish his method until 1861, eight years after the first hypodermic syringe was described.
 
The first true hypodermic syringe was created by Alexander Wood in 1853. 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.

THE PRODUCT – HYPODERMIC SYRINGES

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 others are trans epidermal (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 to work faster. Finally, it is more difficult for the body to reject drugs that are administered by syringe. Trans epidermal drug administration is a relatively new technology, and its effects are generally not as immediate as direct injection.
 
Syringe Design
There are many hypodermic syringes designs available. However, all of them have the same general features, including a barrel, plunger, needle.
 
The barrel is the part of the hypodermic needle that contains the material that is injected or withdrawn. A movable plunger is contained within this tube. The width of the barrel is variable. Some manufacturers make short, wide tubes, and others make long, thin ones. The exact design will depend to some extent on how the device will be used. The end of the barrel to which the needle is attached is tapered. This ensures that only the desired amount of material will be dispensed through the needle. At the base of the barrel away from the needle attachment, two arms flare out. These pieces allow the needle user to press on the plunger with the thumb while holding the tube in place with two fingers. The other end of the barrel is tapered.
 
The plunger, which is responsible for creating the vacuum to draw up materials and then discharge them, is made of a long, straight piece with a handle at one end and a rubber plunger head on the other. The rubber head fits snugly against the walls of the barrel, making an airtight seal. In addition to ensuring an accurate amount of material is drawn in, the squeegee action of the plunger head keeps materials off the inner walls of the tube.
 
The needle is the part of the device that actually pierces the layers of the skin. Depending on how deep the injection or fluid extraction will be, the needle orifice can be thinner or wider, and its length varies. It can also be permanently affixed to the body of the syringe or interchangeable. For the latter type of system, a variety of needles would be available to use for different applications. To prevent accidental needle stick injuries, a protective cap is placed over the top of the needle when it is not in use.

Syringe is made up of 3 parts: Needle, Barrel and Plunger
