What is Cannula and brief about its types

A cannula is a small tube inserted into a person's body cavity, such as their nose, or into a vein by doctors. They're used by doctors to drain fluid, give medication, and deliver oxygen.

 

Cannulas are divided into two categories:

Cannulas for IVs: IV cannulas are short, flexible tubes that doctors insert into a vein.

Cannulas for the nose: Nasal cannulas are flexible tubes that supply oxygen and rest within the nostrils.

Cannula for IV

To place an IV cannula in a person's arm, a doctor or nurse will conduct the following:

 

They will ask the individual to lie or sit with one arm exposed and stretched by their side.

They'll pick a spot in the person's arm to implant the needle. This is usually the person's non-dominant side, and it involves an area with the cleanest veins.

An alcohol wipe will be used to clean this region.

Above this location, they'll tie a tourniquet. A tourniquet is a tight-knit band used by doctors to stop the flow of blood. Although it may be unpleasant, the doctor or nurse will only leave it in place for a minute.

They will warn the person that they will be scratched before inserting the needle into the vein.

The needle's sole purpose is to penetrate the skin and vein in order to enter the cannula into the vein. The needle is withdrawn from the vein as the cannula slips over the needle and into the vein.

Medical tape or a dressing, such as a wrap or specific bandage, is used to secure the cannula in place.

The only discomfort associated with inserting an IV cannula is the scratch caused by the needle puncturing the skin.

 

Nasal cannula

If a person feels faint or anxious during the procedure, they should inform the doctor or nurse who is fitting the cannula.

To place a nasal cannula, a doctor or nurse will do the following:

 

If possible, they will ask the client to sit up straight to allow their lungs to expand.

They'll plug the flow metre into a power outlet and connect it to a nozzle.

They'll turn on the flow metre and make sure the oxygen is flowing freely.

The nasal cannula will be inserted into a person's nose; the prongs on the cannula will keep it in position just inside the nostrils.

They'll coil the tubing around someone's ears and place the plastic slider under their chin to keep it in place.

Every two hours, they will assess the person's comfort and the pressure of the cannula on the skin. Every 4–8 hours, they will check the flow rate.

ESD Bags are used to store sensitive electronic components that can be easily influenced by electrostatic discharge (ESD)

Image
An ESD bag is an antistatic bag used for storing electronic components. These components are susceptible to electrostatic discharge, a form of damage that can cause the entire system to shut down. An ESD bag keeps these electronic parts safe and secure. However, it can't protect all electronic parts from ESD. According to the " Coherent Market Insights " Global Industry Insights, Trends, Outlook, and Opportunity Analysis of ESD Bags Market . ESD Bags Market ESD bags are usually black. They contain vacuum-deposited aluminum. They meet two requirements: low charging and an electrostatic discharge shielding barrier. They also have a longer shelf life. Moisture protection is also a must. Prior to vacuum sealing, a moisture monitor card or desiccant pack is placed in the bag. Bondline offers both metallized and non-metallic barrier bags. The black ones are the most popular. A good ESD bag will protect electronic devices against ESD. Some of them are moisture barrier bags...
