Nitrile Gloves
What are Nitrile Gloves and Why Use Them?
Many people suffer from latex allergies. Nitrile gloves ;are preferred because they are made of synthetic rubber. This means that even if the glove wearer isn't allergic to latex, it still might be a good idea to switch to nitrile. ;
There are definitely uses for latex gloves, but as you'll soon see, nitrile gloves have many compelling advantages. Avoiding allergies is just the beginning. ;
1. Nitrile is also stronger than latex – in fact, it's up to 3 times more puncture resistant! Although you give up some strength and flexibility with nitrile, it's much more puncture-resistant than natural rubber gloves. And when you're dealing with sharp needles, you don't want to take any chances. ;
2. Due to improved manufacturing techniques, nitrile is closing the gap significantly with latex when it comes to comfort and dexterity. It used to be that there was a big difference in tactile sensation between nitrile and latex gloves. While that is still partially true, manufacturing techniques continue to improve, and the difference between latex and nitrile isn't as great as it once was.
All this, combined with the price stability of nitrile, has glove-wearers steadily migrating from latex to nitrile. ;
3. One final reason to "never bet on latex" has to do with price. The price of latex is incredibly volatile since it's made from natural rubber. Nitrile prices are a lot less volatile, and production techniques continue to get better. Since nitrile is a man-made product, the production is not as subject to the whims of Mother Nature as latex. NBR (nitrile butadiene rubber) is used in many different products – aeronautical application, footwear, any kind of molded goods, adhesives, sealants, sponges, foam, and also, of course, gloves.
What is a Glass Syringe?
A glass syringe ;is a glass barrel with a plunger. It is used to draw out or inject fluids and gasses. Glass syringes can have a variety of tips attached to them, from needles for vaccines to a wide tube for feeding baby animals. Originally, all syringes were made of glass, but plastics have emerged as a contending material.
A glass syringe contains much lower levels of contaminants that will react with delicate cures. They may leach traces of certain metals into medicine, but these trace amounts do not react with medicine as poorly as plastics. Unfortunately, the plungers of glass syringes may also be coated with silicone in order to make them slide more easily, and this lubricant can also react poorly with medicine.
Glass syringes are also a better choice when storing blood samples that will later be used for arteriolar blood gas (ABG) testing. An ABG test is used to determine the pH of blood, its level of oxygen and nitrogen, and many other attributes. It's used to diagnose many conditions, such as whether or not the blood is becoming oxygenated in the lungs. A glass syringe is less porous than plastic; therefore, fewer gasses will escape from the blood while it is being held for study.
Spinal Needles
Spinal needles ;vary in their design, usually regarding the tip geometry, but are fundamentally similar and usually come with a stylet and introducer needle. Larger spinal needles may not require an introducer. ; ;
Spinal needles are used to inject analgesia and/or anesthetic directly into the CSF usually at a point below the second lumbar vertebra. Spinal needles enter the cerebral spinal fluid (CSF) through the membranes surrounding the spinal cord. An introducer needle is used in some cases to stabilize the insertion of the needle and aid insertion through the tough skin. ; The needle and stylet are advanced towards the dura in the intervertebral space (the stylet stops tissue from blocking the needle during insertion). An introducer needle is used in some cases to stabilize the insertion of the needle. Once through the dura and in position, the introducer is removed and the removal of the stylet enables CSF to flow into the needle hub. CSF can be collected for diagnostic purposes or a syringe may be connected to the spinal needle to inject anesthetic agents or chemotherapy agents. ;
Whilst Quinke needles tend to cut through the dura (the tough outer membrane), pencil point designs such as the ; Sprotte and Whitacre are designed to part the fibers of the dura rather than cut them, minimizing damage to the dura fibers and reducing the risk of post-dural puncture headaches. ;
Epidural needles (such as the Tuohy needle) are larger, hollow needles that enter the epidural space. ; The curve of the needle is designed to enable an inserted cannula to be threaded into the epidural space at an angle. Once the cannula is in place the epidural needle is removed. Anesthesia and analgesia can be administered via the epidural cannula. ;
What Is a Micro-Cannula?
A micro-cannula ;is a very thin, tiny, flexible hollow tube with a smooth round tip. The sharp end is gone! Instead of many needle sticks, we only need a very few to provide entry points for the cannula. That means fewer needle marks, less pain, and far less probability of bruising.
What Are the Benefits of a Micro-Cannula over a Needle?
Micro-cannula injection requires a single entry point for a large area instead of many as occurs with a traditional needle. Because the tip of the cannula is smooth and rounded, small vessels are simply pushed out of the way instead of being cut – so instead of pain, you’ll most frequently experience little more than pressure.
Surgical Skin Staplers
Surgical skin staplers ;are medical devices that may be used in place of sutures. They can close large wounds or incisions more quickly and be less painful than stitches for patients. They are often used in minimally invasive surgery. They can also be used to close wounds in areas where the skin is tight against bone, in operations to remove organs, or to reconnect parts of internal organs.
Surgical skin staplers are generally made of plastic and loaded with a disposable cartridge of surgical staples. The staplers come in both reusable and disposable models. They resemble construction or industrial staplers and are designed to insert and close several staples at once.
The devices may be used internally to seal tissue during surgery. They are useful in minimally invasive surgery because they require only a narrow opening and can quickly cut and seal tissue and blood vessels. Skin staplers are used externally to close skin under high tension, such as on the skull or the trunk of the body.
What Is a Nebulizer Mask?
A nebulizer mask ;looks and is very similar to a regular oxygen mask commonly used in the hospital. Unlike a mouthpiece, it covers the mouth and nose and is usually held onto the face using an elastic band. Nebulizer treatments are commonly used by people who have respiratory disorders such as asthma, chronic obstructive pulmonary disease (COPD), or cystic fibrosis.
There are many different types of medications that can be nebulized including glucocorticoids, bronchodilators, antibiotics, and even just plain saline which is used to thin mucus secretions. Examples of some of the most commonly used medications include albuterol and budesonide.
Nebulizer machines require some training to be used properly, you should receive this training from a healthcare provider, nurse, or respiratory therapist prior to use. It is also important that medications that should not be mixed are not mixed and that the proper amount of medications is used.
Advantages of a Nebulizer Mask
The elastic band holding the mask in place makes it easier to be used passively because unlike a mouthpiece it doesn't have to be held in place. This is especially helpful for people who may be too weak to hold the mouthpiece or lack the necessary mobility to do so.
Some people may simply prefer the mask because it allows them to retain the use of their hands throughout the duration of the treatment.
Unlike a mouthpiece, the mask does not require you to breathe in a very specific way. When you use a mouthpiece the correct method of breathing is in through the mouth and out through your nose.
For small children or those who may have disabilities, such as a learning disability, this could be challenging. Not only must you be able to follow these instructions but it requires a certain amount of continual concentration throughout the duration of the treatment.
